Description

Technical Field

[0001] The present invention relates to the technical field of solar energy equipment, in particular to a solar photovoltaic array system with a self-cleaning and maintenance function. Background Art

[0002] A solar photovoltaic array system is an energy system that uses photovoltaic technology to convert solar energy into electricity. It primarily consists of photovoltaic modules, inverters, mounting systems, and electrical accessories. Advantages of this system lie in its renewable nature, modular design, and low maintenance requirements. It is widely used in residential, commercial, and large-scale power plants to reduce greenhouse gas emissions and lower energy costs. However, in actual operation, photovoltaic array systems face several challenges, particularly in terms of maintenance and performance in harsh environments. The following are some of the main issues currently encountered in solar photovoltaic array systems:

[0003] First, prolonged exposure to intense sunlight can affect photovoltaic mounts, causing them to be subject to high temperatures. Different materials, due to varying coefficients of thermal expansion, can generate internal thermal stress. This can lead to structural fatigue or damage, impacting the stability of the entire mount and the performance and lifespan of the solar panels. Secondly, due to high temperatures and environmental factors such as temperature fluctuations, humidity changes, and ultraviolet radiation, snail patterns and surface cracks may appear on the surface of the solar photovoltaic array. This not only affects the aesthetics of the components but can also reduce the panels' photovoltaic conversion efficiency and further diminish photovoltaic power generation. Currently, manual cleaning and repair are often used, which is a significant workload for large-scale solar photovoltaic array systems.

During the sliding process of the screw rod driving slide 24, the driving gear set 241 inside the screw rod driving slide 24 will mesh with the tooth plate 211 and rotate, and the rotating driving gear set 241 will mesh and transmit the driven gear set 242 on its side, and then the driven gear set 242 will drive the cam 243 in the middle position to rotate, and the cam 243 will rotate. During the process, the limiting slide 244 is pushed intermittently, so that the limiting slide 244 moves back and forth along the specified path while compressing the return spring 246. The reciprocating limiting slide 244 pushes and pulls the screw rod 245, and in the process of pushing and pulling the screw rod 245, the screw rod 245 cooperates with the butterfly plate 251 to rotate and drive the lightweight roller tube 25, so that the lightweight roller tube 25 rotates along the bearing end of the screw drive slide 24. Before the lightweight roller tube 25 rotates or is in the initial position, the water inside the water wheel groove 212 will enter the water chamber 254 through the pipeline assembly 23, and then enter the water flushing plate 2511 from the water chamber 254 to wash the solar array 3 covered by the water flushing plate 2511, and the flushing water will go along the water flushing plate The attached plate 2511 is transported to the water outlet 214 by the output water interface 256 and the pipeline assembly 23, and is transported to the water reservoir by the water outlet 214. When the lightweight roller tube 25 rotates, the screw rod 245 will push the water piston 252 to slide along the inner wall of the lightweight roller tube 25. While pushing the glue piston 253 to move, the water interface 256 will be gradually blocked to stop flushing the solar array 3. Then the lightweight roller tube 25 will drive the soft wipe 2512 to rotate to a position in contact with the solar array 3, wipe the flushing position dry, and then the lightweight roller tube 25 will continue to rotate and gradually rotate the glue attached plate 2513 to a position in contact with the solar array 3. During this process, the water piston 252 will gradually come into contact with the glue piston 253. , and pushes the glue piston 253 to move. When the glue pressing plate 2513 is in the initial position of the water flushing plate 2511, the water piston 252 will push the glue piston 253 to remove the blockage of the glue interface 257, and then the glue supply pump 221 will suck the liquid glue inside the glue box 22 into the interior of the glue pressing plate 2513, and flow to the surface of the solar array 3. As the glue supply pump 221 applies pressure, the liquid glue will be pressed into the gaps on the surface of the solar array 3, and then the liquid glue corresponding to the surface of the solar array 3 will be sucked into the interior of the glue suction tube cavity 27, and under the suction of the suction pump 222, it will flow back into the interior of the glue box 22, and then the lightweight roller 25 will continue to rotate, so that the soft hanging cotton pad 2514 will evenly coat the liquid glue retained on the surface of the solar array 3.

The cam 243 is driven by the toothed plate 211 to drive the driving gear set 241 in a meshing manner during the movement of the screw-driven slider 24, so that the cam 243 pushes the screw rod 245 to move back and forth in a straight line in an intermittent manner, and in the process of movement, the butterfly hole plate 251 is cooperated to drive the lightweight roller 25 to rotate, so that the rotating lightweight roller 25 can cooperate with the glue supply pump 221, the suction pump 222, the water piston 252, the glue piston 253, the pipeline assembly 23 and the telescopic piston rod 26 to realize the washing, wiping, drying, gluing and wiping operations on the surface of the solar array 3 within a small moving distance, so as to deal with dirt, snail marks and gaps on the surface of the solar array 3. Compared with the current manual processing method, it can greatly reduce the workload of the staff, ensure the working efficiency of the solar array 3, and be more conducive to improving the service life of the solar array 3, and effectively alleviate the aging problem of the solar array 3.

[0052] Working principle: When working, first assemble the solar photovoltaic array system according to the supporting body 1 in the figure, then connect the water pump 121 to the water reservoir, and connect the outlet pipe 214 to the filtered water tank inside the water reservoir. Then, after the circuit system of the solar photovoltaic array system is improved, it can be used. During use, as the sun rises, sunlight will shine on the surface of the photosensitive and thermal sensing elements on the water pump 121 (the photosensitive and thermal sensing elements will dynamically detect the intensity of sunlight and the heat conducted by sunlight, and feedback the detected values to the control end of the water pump 121, so as to dynamically adjust the power of the water pump 121. The maximum value of the adjustment will not exceed the maximum rated power of the water pump 121). As the temperature rises and the light intensity increases, the power of the water pump 121 will gradually increase, and the amount of water entering the front connecting pipe rack 12 will gradually increase. Then the water will enter the support rack 11 along the front connecting pipe rack 12, and the support rack 11 will pass through the first connecting pipe rack. The water pipe 112 enters the interior of the array positioning pipe rack 13, and then enters the interior of the rear connecting pipe rack 15 through the second connecting water pipe 151 from the array positioning pipe rack 13, and is diverted to both sides by the rear connecting pipe rack 15 into the interior of the rear supporting pipe rack 11, and is transported upward along the supporting pipe rack 11 into the interior of the movable drain pipe 114. While compressing the hydraulic spring 1151, the extension valve stem 115 is pushed upward, so that the extension valve stem 115 pushes the movable steel frame 14 upward through the movable connecting piece 116, and then the movable steel frame 14 will drive the structure it carries to dynamically rotate with the upper end of the front supporting pipe rack 11 as the fulcrum, so that the solar photovoltaic array system can be adjusted according to the sunlight. Dynamic adjustment and comprehensive cooling treatment of the supporting body 1. At the same time, the water flow of the upward extended valve stem 115 will flow through the valve seat 1142, the interface on the side of the movable drain pipe 114, the corresponding pipeline assembly 23 and the water inlet pipe 213 into the interior of the water wheel groove 212, and hydraulically drive the water wheel body 217, so that the water wheel body 217 drives the two-way reciprocating screw rod 216 to rotate, and the rotating two-way reciprocating screw rod 216 will drive the screw rod to drive the slide 24 to slide back and forth along the slide frame 21. During the sliding process of the screw rod driven slide 24, the driving gear set 241 inside the screw rod driven slide 24 will mesh with the tooth plate 211 and rotate, and the rotating driving gear set 241 will The driven gear set 242 on its side is meshed and driven, and then the driven gear set 242 will drive the cam 243 in the middle position to rotate, and the cam 243 will intermittently push the limiting slide 244 during the rotation process, so that the limiting slide 244 moves back and forth along the specified path while compressing the return spring 246. The reciprocating limiting slide 244 pushes and pulls the spiral rod 245, and in the process of pushing and pulling the spiral rod 245, the spiral rod 245 cooperates with the butterfly hole plate 251 to rotate and drive the lightweight roller 25, so that the lightweight roller 25 rotates along the bearing end of the screw drive slide 24. Before the lightweight roller 25 rotates or when it is in the initial position,The water inside the water wheel groove 212 will enter the interior of the water chamber 254 through the pipe assembly 23, and then enter the interior of the water flushing plate 2511 from the water chamber 254 to wash the solar array 3 covered by the water flushing plate 2511, and the flushing water will be transported along the water flushing plate 2511 through the output water interface 256 and the pipe assembly 23 to the water outlet pipe 214, and then transported from the water outlet pipe 214 to the water reservoir. When the lightweight roller tube 25 rotates, the spiral rod 245 will push the water piston 252 to slide along the inner wall of the lightweight roller tube 25, and while pushing the glue piston 253 to move, it will gradually block the water interface 256, stop flushing the solar array 3, and then the lightweight roller tube 25 rotates. The roller tube 25 will drive the soft wiper 2512 to rotate to the position of contact with the solar array 3, wipe the flushing position and dry it, then the lightweight roller tube 25 will continue to rotate and gradually rotate the glue pressing plate 2513 to the position of contact with the solar array 3. During this process, the water piston 252 will gradually contact the glue piston 253 and push the glue piston 253 to move. When the glue pressing plate 2513 is in the initial position of the water flushing plate 2511, the water piston 252 will push the glue piston 253 to remove the blockage of the glue interface 257, and then the glue supply pump 221 will suck the liquid glue inside the glue box 22 into the space where the glue piston 253 spring is expanded, and the space is filled with glue. The liquid glue enters the interior of the glue pressing plate 2513 and flows to the surface of the solar array 3. As the glue supply pump 221 applies pressure, the liquid glue will be pressed into the gap on the surface of the solar array 3. Then the glue supply pump 221 stops. At the same time, due to the movement of the glue piston 253, the hydraulic liquid inside the hydraulic chamber 255 will be pushed into the interior of the telescopic piston rod 26, causing the telescopic piston rod 26 to gradually extend. At this time, the one-way valve 271 will open under the action of the liquid glue pressure, the suction pump 222 and the negative pressure of the telescopic piston rod 26, and then the liquid glue corresponding to the surface of the solar array 3 will be sucked into the interior of the glue suction tube cavity 27, and then will flow back into the glue box under the suction of the suction pump 222. 22, and then the lightweight roller tube 25 will continue to rotate, so that the soft hanging cotton pad 2514 moves to the glue pressing position on the surface of the solar array 3, and evenly applies the liquid glue retained on the surface of the solar array 3, so that a layer of protective glue film is formed on the surface of the solar array 3 (the glue film will be removed during the cleaning process after it dries). Then the lightweight roller tube 25 will be reset to its initial state under the action of the reset spring 246. The above processing process is achieved by the screw driving the slide 24 to drive the lightweight roller tube 25 to move stepwise along the surface of the solar array 3 (each processing area is connected or has a small overlapping part, and there is no gap), and the above processing process will be continuously executed in conjunction with the water pump 121.

The specific time is adjusted according to actual needs to adjust the power of the water pump 121 (this power refers to the maximum rated power of the water pump 121 when it is working, and you can choose to replace the water pump 121 with a different rated power).
