Description

Technical Field

[0001] This utility model belongs to the field of clean energy technology, and more specifically, it relates to an automatic dust and snow removal device for photovoltaic modules. Background Technology

[0002] Photovoltaic modules primarily collect sunlight through solar panels. Through energy conversion, solar radiation is directly or indirectly converted into electrical energy via the photoelectric effect or photochemical effect. This electrical energy is then stored in batteries and discharged externally as needed, thus achieving efficient utilization of solar energy. Solar panels are typically exposed directly in open areas, and over time, dust and snow can accumulate on them, hindering sunlight absorption and potentially breaking the panels. Therefore, automatic dust and snow removal devices are needed to clean the surface of the solar panels.

[0003] Based on the above, existing automatic dust and snow removal devices for solar panels typically use cleaning brushes to repeatedly brush away the dust or snow covering the surface of the solar panels when they are not in use at night. However, the brushes cannot adsorb dust and other impurities without being moistened, resulting in limited cleaning effectiveness. In addition, continuous dry rubbing on the solar panels can also damage their surface. Therefore, the use of this type of dust and snow removal device is somewhat limited. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an automatic dust and snow removal device for photovoltaic modules, thereby solving the problem that existing dust and snow removal devices for photovoltaic modules are prone to damaging the photovoltaic modules during cleaning.

[0005] This utility model provides an automatic dust and snow removal device for photovoltaic modules, which is achieved by the following specific technical means:

[0006] An automatic dust and snow removal device for photovoltaic modules includes a base. Two sets of rectangular bases are placed parallel to each other. Insertion holes are provided at both ends of the base, into which vertical fixing frames are inserted. The vertical fixing frames inserted into the two sets of bases are of unequal length. A fixing plate is provided at the lower part of each vertical fixing frame, and the fixing plate is fixed to the base by fixing bolts. An oblique fixing frame is fixedly connected to one side of each vertical fixing frame via a fixing seat and a first bolt pair. A U-shaped connecting rod is fixedly connected to the upper ends of the vertical and oblique fixing frames via a fixing seat and a first bolt pair. A mounting plate is connected above the connecting rod via a second bolt pair. A sleeve is fitted onto the bolt of the second bolt pair, and the sleeve supports the connecting rod between the mounting plate and the mounting plate. Two sets of mounting plates are parallel to each other, and a mounting groove is provided on opposite sides of each mounting plate. A photovoltaic module is placed in the mounting groove. A cleaning brush surface is placed on top of each photovoltaic module, and a brush is adhered to the bottom surface of the cleaning brush surface. Two second fixing steel wires are provided below the photovoltaic module. A spraying mechanism is provided below the photovoltaic module.

[0007] Furthermore, each end of the mounting plate is rotatably connected to a set of pulleys, and the center of one side of the pulley is fixedly connected to the shaft of the drive motor. The pulleys at both ends are fitted with a first fixing steel wire, which is in the shape of a ring. The cleaning brush surface and both sides of the second fixing steel wire are connected to the first fixing steel wire.

[0008] Furthermore, the spraying mechanism includes a water spray pipe with multiple sets of nozzles evenly spaced on it. All nozzles face the photovoltaic module. The water spray pipe is connected to a water pump through a pipe section one, and the water pump is connected to a water storage tank through a pipe section two. A water inlet is provided on one side of the water storage tank, and a sealing plug is inserted into the water inlet.

[0009] Furthermore, both ends of the water spray pipe are fitted into the mounting bracket, and the mounting bracket is fixed to the connecting rod by a third bolt pair.

[0010] Furthermore, a water injection pipe is connected to one side of the water storage tank, the water injection pipe is inclined upward, and a guide channel is connected to the other end. A collection channel is connected above the guide channel. The collection channel is located below the photovoltaic module, and lifting lugs are set on both sides of the collection channel. Hooks are set at the lower ends of the two sets of mounting plates, and the lifting lugs are suspended on the hooks.

[0011] Furthermore, the connection between the collection tank and the guide tank is provided with dense filter holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, by setting up a water pump, a water storage tank, a water spray pipe and nozzles, allows the water in the water storage tank to be drawn into the water spray pipe before cleaning the photovoltaic modules at night. Then, the water is sprayed onto the cleaning brush surface through the nozzles to moisten it. After being moistened, dust is easily attracted, resulting in a better cleaning effect on the photovoltaic modules. At the same time, it avoids continuous dry friction on the photovoltaic modules during cleaning, which can damage the surface of the photovoltaic modules.

[0014] 2. This utility model incorporates a water injection pipe, a diversion channel, and a collection channel. The collection channel collects the snow cleaned off the photovoltaic modules. After the snow melts, it is recycled into the water storage tank through the diversion channel and the water injection pipe. Generally, it is not necessary to manually add water to the water storage tank. By setting a filter hole at the bottom of the collection channel, it is prevented that fallen leaves and other debris cleaned off the photovoltaic modules enter the collection channel and then flow into the water storage tank with the snow melt water, causing blockage.

A sleeve 31 is fitted on the bolt of the second bolt 9, and the sleeve 31 is supported between the connecting rod 8 and the mounting plate 10. There are two sets of mounting plates 10, which are parallel to each other. A placement groove is opened on the opposite side of the mounting plate 10, and a photovoltaic module 11 is placed in the placement groove. A cleaning brush surface 14 is covered on the top of the photovoltaic module 11. A brush is attached to the bottom surface of the cleaning brush surface 14. Two second fixing steel wires 15 are set below the photovoltaic module 11. A spraying mechanism is set below the photovoltaic module 11.

[0027] Among them, such as Figure 1 and Figure 2 As shown, each end of the mounting plate 10 is rotatably connected to a set of pulleys 12. The center of one side of the pulley 12 is fixedly connected to the shaft of the drive motor. The pulleys 12 at both ends are fitted with first fixing wires 13, which are in the shape of rings. The cleaning brush surface 14 and the second fixing wire 15 are both connected to the first fixing wires 13. The second fixing wire 15 is controlled by the drive motor to rotate around the two sets of pulleys 12. During the day when the photovoltaic module 11 is working, only the two first fixing wires 13 are placed on the surface of the photovoltaic module 11. At night when the photovoltaic module 11 enters the cleaning state, the cleaning brush surface 14 on the back is rotated to the surface of the photovoltaic module 11 through the drive motor and the pulleys 12 to perform cleaning operations.

[0028] Among them, such as Figure 2 and Figure 4As shown, the spraying mechanism includes a water spray pipe 16, with multiple sets of nozzles 17 evenly spaced on the water spray pipe 16, all of which face the photovoltaic module 11. Both ends of the water spray pipe 16 are fitted into the mounting bracket 18, which is fixed to the connecting rod 8 by a third bolt pair 19. The water spray pipe 16 is connected to a water pump 21 via pipe section 20, and the water pump 21 is connected to a water storage tank 23 via pipe section 22. A water inlet 24 is provided on one side of the water storage tank 23, and a sealing plug is inserted into the water inlet 24.

The water injection pipe 25 is inclined upward and connected to a guide channel 26 at the other end. A collection tank 27 is connected above the guide channel 26.

After the snow melts, it is recycled into the water storage tank 23 through the guide channel 26 and the water injection pipe 25. Generally, it is not necessary to manually add water to the water storage tank 23. By setting filter holes 28 at the bottom of the collection tank 27, it is prevented that fallen leaves and other debris cleared from the photovoltaic module 11 enter the collection tank 27 and then flow into the water storage tank 23 with the snow melt water, causing blockage.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this invention, the second fixed steel wire 15 is controlled by a drive motor to rotate around two sets of pulleys 12. During the daytime operation of the photovoltaic module 11, only the two first fixed steel wires 13 are placed on the surface of the photovoltaic module 11.

The snow that is cleaned off enters the collection tank 27. After the snow in the collection tank 27 melts and is filtered through the filter hole 28, it is collected into the water storage tank 23 through the guide channel 26 and the water injection pipe 25 as spray water for wetting the cleaning brush surface 14. It should be noted that before cleaning the photovoltaic module 11 at night, the spray water in the water storage tank 23 must be led to the spray pipe 16 through the water pump 21, and then the spray water is sprayed onto the cleaning brush surface 14 through the nozzle 17 for wetting.
