Solar road studs, as an important part of modern transportation infrastructure, play a pivotal role in ensuring road safety. Whether in the dark of night, or bad weather conditions, they can continue to light, for drivers to clearly outline the road contours, lane boundaries and dangerous areas, effectively guiding the driver's line of sight, significantly reducing the incidence of traffic accidents. For example, in some mountainous areas of the road, due to the many curves, poor line of sight, solar road studs can be in the night and bad weather, through the flashing lights to remind drivers of the road ahead, reduce the road due to see the accidents caused by the road.
However, effective maintenance is essential to keep solar road studs in optimal working condition at all times. If not properly maintained, the road studs may suffer from abnormal light emission, shortened battery life and other problems, thus weakening their proper function of traffic safety and security. This not only affects the traveling experience of road users, but also poses a potential threat to life and property safety. Therefore, it is important to understand and master the correct maintenance method of solar road studs.
The first step in the maintenance of solar road studs is to ensure that the surface of the road studs is clean. This is an important factor in ensuring that the optical properties of the solar road studs are not affected, and that the solar panels can fully absorb the sunlight and provide sufficient power for the operation of the road studs.
Cleaning frequency is mainly based on the environment in which the road stud to determine. In the dust, gravel more road, such as construction sites near the edge of the desert highway, due to a large number of particles are easy to quickly cover the surface of the road stud, blocking the solar panels to absorb the sunlight and LED light, it is recommended that at least once a month to clean. In the vehicle exhaust emissions serious, industrial pollution in the region, the surface of the road stud is easy to adhere to the oil and chemical pollutants, these substances not only affect the aesthetic, but also may corrode the road stud shell, the frequency of cleaning should be maintained at about once a month to prevent the long-term accumulation of pollutants on the road stud caused by damage.
And in the environment of cleaner areas can be appropriate to reduce the cleaning frequency.
Microfiber cloth: adsorption of dust ability, soft texture, will not scratch the surface of the road stud, is the first choice for cleaning tools.
Soft Brush: Ideal for penetrating deep into the crevices and corners of the road stud to remove stubborn dirt and debris.
mild detergent: recommended diluted neutral detergent solution, can effectively remove dirt, but will not corrode the road studs material.
Pre-treatment: Use a soft bristle brush to gently sweep away large particles of dust and debris from the surface of the road stud to avoid scratching the surface with subsequent wiping particles.
Initial wipe: Soak a soft microfiber cloth in a diluted neutral detergent solution, wring it out until half-dry, and gently wipe the solar panels, LED lights and housings. For stubborn stains, you can add moderate force, but do not use excessive force.
Residual Cleaning: Wash the soft cloth with water and wipe the dowel twice to thoroughly remove the cleaning agent residue and prevent corrosion.
Drying: Wipe the surface of the road stud with a dry, soft cloth to ensure that no moisture remains and to prevent moisture from penetrating and causing short circuits or rusting of parts.
Solar panels are the energy source of solar road studs, and their performance is directly related to whether the road studs can continue to work stably. Regular checking of the solar panels to ensure that they are in good condition is a key part of the maintenance of solar road studs.
Visual inspection is the most basic and intuitive method of solar panel inspection. First, look carefully at the surface of the solar panel to see if there are any cracks, breaks or scratches. Next, look for dirt buildup on the surface of the solar panel, such as dust, leaves, bird droppings, and so on. In addition, pay attention to the edges and frames of the solar panel for signs of looseness, deformation or corrosion.
In addition to visual inspection, the output power of solar panels should be tested regularly to accurately determine whether they are performing properly. To test the output power of solar panels, you can use professional solar panel testers, which can accurately measure the current, voltage and power parameters of solar panels under different lighting conditions. If you do not have a professional tester, you can also use a multimeter for simple measurement.
The battery in the solar road stud, as a key component for storing solar energy and providing electricity for the road stud to glow at night, its performance and life expectancy directly affects the stability and continuous effectiveness of the road stud. Therefore, reasonable maintenance of the battery is an important part to ensure the normal operation of the solar road stud.
Solar road studs use a variety of battery types, common nickel-metal hydride batteries, lithium batteries and lead-acid batteries, each type of battery has a different life expectancy:
Nickel-metal hydride batteries: usually can be charged and discharged 500 - 1,000 times the cycle. Nickel-metal hydride (Ni-MH) batteries: can usually perform 500 - 1000 charge/discharge cycles. If a complete charge/discharge cycle is performed once a day, the theoretical service life is about 1.5 - 3 years.
Lithium batteries: Better performance, up to 1000 - 2000 charge/discharge cycles. Based on the same frequency of use, the service life can be 3 - 6 years.
Lead-acid battery: Although the cost is lower, the number of charge/discharge cycles is relatively small, about 300 - 500 times, under normal use, the life span is about 1 - 2 years.
However, in actual use, these theoretical lifespans are significantly affected by a variety of factors:
Temperature: High temperatures accelerate the internal chemical reaction of the battery, leading to aging of the plates and drying out of the electrolyte; low temperatures increase the internal resistance of the battery, reduce the activity of the chemical reaction, and affect the battery capacity and charging/discharging performance.
Charging and discharging mode: excessive charging will generate too much heat, accelerating the decomposition of internal battery chemicals; excessive discharging will lead to plate sulfurization, reducing the battery's power storage capacity. If the charging control circuit fails, leaving the battery in a long-term overcharge or overdischarge state, the battery life may be shortened by more than half.
When the battery of the solar road stud has the following conditions, you need to consider replacing it:
Luminescence time shortening: the light-emitting time of the road stud is significantly shorter, it is likely that the battery's ability to store electricity has decreased. With the aging of the battery, the internal chemical activity is reduced, and can not store enough electricity.
Luminous brightness weakened: If the brightness of the road stud is significantly dimmer, it may be that the battery power is insufficient to provide sufficient driving voltage for the LED lights, resulting in reduced luminous intensity.
Charging abnormality: the battery charging time is significantly longer, or can not be fully charged under normal light, indicating that the battery charging performance has been seriously degraded.
When solar road stud is exposed to the outdoors for a long period of time and subjected to the crushing and impact of vehicles as well as the erosion of the natural environment, its components may become loosened or damaged. Timely detection and treatment of these problems is essential to ensure the normal operation and service life of solar road studs.
When checking whether the parts of the solar road stud are loose, the first thing to do is to check the appearance. You can gently shake the road stud with your hand to feel its overall stability. If the road stud has obvious shaking, that its fixation with the ground may be a problem, you need to further check the installation parts, such as whether the installation screws are loose, fall off, or whether the adhesive at the bottom of the road stud is ineffective. In some of the road frequently subjected to large vehicles run over the road, the connection between the road stud and the ground is more likely to appear loose.
Next, carefully look at the various components of the solar road studs, such as solar panels, LED lampshade, shell, etc., to observe the connection between them whether there is an increase in the gap between the parts, sealant cracking and other phenomena.
In addition, forroad studs with internal wiring connections, it is necessary to open the shell (under the premise of ensuring safety and without damaging the road stud), and check the wiring soldering points and connections. Loose solder joints can lead to poor contact with the circuit, causing the road stud to work intermittently or not.
Repair and replacement of loose parts varies depending on the type of part and the cause of the looseness. If the mounting screws are loose, use a suitable screwdriver or wrench to retighten the screws to the specified torque value. During the tightening process, pay attention to the uniformity of force to avoid slipping of the screws or damage to the studs due to over-exertion of force. If the screws are damaged or lost, replace them with screws of the same specification.
For solar road studs loosening due to adhesive failure, you need to clean off the bottom of the road studs and the installation of the old adhesive, the use of cleaners to remove residual glue and impurities, to ensure that the surface is clean and dry. Then, apply an appropriate amount of high-quality adhesive, such as epoxy resin adhesive, to re-fix the road stud in place. During the curing process of the adhesive, keep the road stud stable and avoid its movement.
When the components of the solar road studs are damaged, they should be replaced in time. If the solar panel is cracked, broken, and can not generate electricity normally, you need to replace the solar panel with a new one . Choose a solar panel that matches the originalroad stud model and make sure its power, size and other parameters are consistent . During the replacement process, carefully remove the old solar panel, be careful not to damage other parts, and then follow the correct installation method to fix the new solar panel and connect the wiring.
If the LED lampshade is broken or damaged, it will affect the light-emitting effect and waterproof performance of the road stud, and also need to be replaced. Purchase the appropriate LED lampshade, remove the damaged lampshade, clean the installation area, and then install a new lampshade to ensure that the lampshade and the road studs shell fit tightly and seal well.
If the spigot housing is severely damaged, resulting in exposure of internal components or reduced protection, the entire spigot should be replaced. When replacing the road studs, follow the installation specification to ensure that the newroad studs are firmly installed, accurately positioned, and consistently spaced and aligned with the surroundingroad studs to ensure the consistency and effectiveness of the road marking.
Solar road studs are mainly used in outdoor, need to face different extreme weather conditions, in different weather conditions, you need to take targeted protective measures for solar road studs to ensure their normal operation.
Rainstorms can easily cause water to accumulate around the road stud or even seep inside, damaging the electronic components. You need to ensure smooth drainage at the installation location: check the drainage holes regularly, clear the leaves, mud and other clogging debris in a timely manner to ensure the normal operation of the drainage system, to avoid damage to the road stud due to water.
Continuous high temperature will make the road stud working temperature soaring, accelerating the aging of the battery and component performance degradation. Heat-insulating materials, such as heat-insulating mats, can be laid around the road stud to block the heat transfer from the road surface. At the same time, avoid maintenance during high-temperature hours to prevent burns and additional damage to the road stud.
Low temperature causes the battery capacity to plummet and the electrolyte to solidify, which affects the operation of the road stud. In snowy days, we should clean up the snow on the solar panel in time to avoid blocking the charging effect; when cleaning up, prohibit the use of sharp tools to prevent scratching the surface of the road stud to ensure its normal operation.
Strong winds may blow down debris and damage the road stud or make it loose. It is necessary to regularly check the firmness of the installation, increase the fixing screws or replace the strong base; before the arrival of strong winds, clean up the surrounding billboards, tree branches and other items that are easily blown by the wind; if you find any damaged or looseroad studs, immediately repair or replace them to eliminate potential safety hazards.
Detailed record of the maintenance information of the solar road stud is an important work that can not be ignored, which provides a strong support for the long-term stable operation and scientific management of the road stud. Maintenance records are like the solar road stud's “health file”, recording the bits and pieces of its use in the process, to help us find potential problems in a timely manner, to develop a reasonable maintenance program, to extend the service life of the road stud.
Every time you maintain, you should accurately record the time of maintenance, accurate to the specific date and time point . This helps us to analyze the working condition of the road stud over time, such as by comparing the maintenance records of different times, to determine whether the frequency of the road stud problem increases, so as to adjust the maintenance strategy in a timely manner.
Maintenance content is also a key part of the record . To describe in detail the specific operations carried out by the maintenance, such as cleaning solar studs, record the type of detergent used, cleaning methods and steps; check the solar panel, record whether to find cracks, dirt buildup and treatment measures; test the battery, record the battery voltage, capacity and other parameters, as well as the existence of charging anomalies and other issues. These detailed records of maintenance content can provide a reference for subsequent maintenance work, and when similar problems occur again, solutions can be quickly found.
In addition, the information of replacement parts must also be recorded clearly. If solar panels, batteries, LED covers, etc. are replaced during maintenance, the name, brand, model, date of manufacture, and reason for replacement should be recorded. This not only helps us to keep track of the quality and service life of the parts, but also makes it easier to find and purchase the right parts when needed.
Regular and proper maintenance is very important for solar road studs. It can ensure that the solar road studs always keep good working condition, and steadily play its role of guiding traffic and ensuring safety, effectively reduce the probability of traffic accidents, and provide reliable safety for road users. At the same time, reasonable maintenance can extend the service life of the solar road studs, reduce the replacement and maintenance costs, and improve the investment efficiency of transportation facilities.
