They are usually composed of solar cells, a support structure, and other related components. When installing a photovoltaic module, a photovoltaic module fixing device is required to install and fix it.

[0003] A Chinese patent with the publication number CN118889956B discloses a photovoltaic module installation device and a photovoltaic system, including a lower frame. The top of the lower frame is fixed with an upper frame. The front side of the lower frame extends horizontally forward, and the rear side of the lower frame extends vertically upward. A first frame is provided on the front side of the upper frame. The first frame is parallel above the front side of the lower frame and is hinged to the front side of the lower frame. A second frame is provided on the rear side of the upper frame. A first assembly frame is provided inside the first frame, and a second assembly frame is provided inside the second frame. Through a plurality of assembly frames, when the first electric cylinder is energized and the rod moves forward, it pushes the second frame to deflect upward around the second rotating shaft. The second frame drives the first frame to deflect upward, and the first frame and the second frame drive the first assembly frame and the second assembly frame to deflect upward. When the first frame and the second frame deflect upward to the same inclined plane, they also drive the first assembly frame and the second assembly frame to deflect upward to the same inclined plane, and the photovoltaic panel in the first assembly frame will also face the sun, thereby improving the energy absorption effect.

Also, since a plurality of circular gears 251 are sequentially provided on one side of the circular gear 251, through the cooperation of the circular gears 251, a plurality of cleaning brushes 252 all rotate, so that the cleaning brush 252 rotates while moving, facilitating the cleaning of the attachments on the photovoltaic panel 12, solving the problem of inconvenient and rapid cleaning of the photovoltaic panel 12, and being beneficial to the conversion of light energy into electrical energy.

[0029] As Figure 1 and Figure 6 shown, a water delivery pipe 24 is fixedly connected to the top side wall of the moving frame 25. A plurality of water spray pipes 241 are fixedly connected to the bottom of the water delivery pipe 24, and rotary nozzles are installed on the water spray pipes 241. A collection tank 36 is fixedly connected to the bottom of the water collecting tank 35. A communicating pipe 38 is fixedly connected to the bottom of the collection tank 36. One end of the communicating pipe 38 is provided with a water tank 381 and a water pump 382. The output end of the water pump 382 is provided with a telescopic pipe 383, and one end of the telescopic pipe 383 is fixedly connected to the water delivery pipe 24 in a communicating manner.

[0030] The communicating pipe 38 and the telescopic pipe 383 provided by the present invention are used to convey water flow during use. After the bird droppings or other attachments on the photovoltaic panel 12 are dried and caked, it is not easy to be cleaned and dropped by the cleaning brush 252, and the photovoltaic panel 12 needs to be rinsed. The filtered water flows into the water tank 381 through the communicating pipe 38. Under the action of the water pump 382, the water in the water tank 381 is conveyed upward to the water delivery pipe 24 through the telescopic pipe 383. The water in the water delivery pipe 24 is sprayed out through the water spray pipes 241, and rotary nozzles are provided on the water spray pipes 241, facilitating the expansion of the spraying area and improving the cleaning effect of the photovoltaic panel 12.

[0031] As Figure 5 and Figure 6 shown, a drain pipe 37 is fixedly connected to the bottom of the collection tank 36, and a control valve is installed on the drain pipe 37. The scraper 33 is slidably connected to the water collecting tank 35, and the bottom of the scraper 33 is attached to the inner wall of the bottom of the collection tank 36. A plurality of filter holes are opened at the bottom of the water collecting tank 35. A filter plate is installed at the bottom of the collection tank 36, and the filter plate is arranged at the top of one end of the communicating pipe 38.

[0032] The collection tank 36 and the filter plate provided by the present invention are used to filter the mud in water during use. Large-particle impurities are filtered through the water chute 35, and small-particle impurities are filtered through the collection tank 36. The scraper 33 is in contact with the bottoms of the water chute 35 and the collection tank 36 respectively, facilitating scraping the sediment and impurities at the bottoms of the water chute 35 and the collection tank 36 to prevent blockage. By providing the drain pipe 37, it is convenient to discharge the small particles and impurities in the collection tank 36.

[0033] As Figure 2 As shown, a drying box 26 is fixedly connected to the bottom side wall of the moving frame 25. A plurality of fans 261 are provided inside the drying box 26. A plurality of heating wires 262 are fixedly connected to the bottom of the drying box 26.

[0034] The drying box 26 provided by the present invention is used to quickly dry the moisture on the surface of the photovoltaic panel 12 during use. After the rinsing is completed, the fans 261 and the heating wires 262 need to be powered on. The heat of the heating wires 262 is quickly sprayed on the photovoltaic panel 12 through the fans 261 for drying to reduce dust adhesion. If the light intensity is high, drying may not be required.

[0035] As Figure 6 and Figure 7 As shown, four telescopic mechanisms are provided below the bottom plate 1. The telescopic mechanisms are respectively arranged at the four corners of the bottom plate 1. The telescopic mechanism includes a fixed column 4. A sliding cavity is formed inside each fixed column 4. A telescopic column 41 is slidably connected inside each sliding cavity. The top of each sliding cavity is rotatably connected to a third lead screw 43 through a bearing. The telescopic columns 41 are all threadedly connected to the outside of the third lead screw 43. A third bevel gear 44 is fixedly connected to the top end of the third lead screw 43. Each fixed column 4 is rotatably connected to a fourth bevel gear 45 through a rotating shaft. The fourth bevel gears 45 are respectively meshed with the adjacent third bevel gears 44. A rotating block 42 is fixedly connected to one end of each rotating shaft.

[0036] Due to the diversification of current building settings, the top may not be flat, and the bottom surface of the open space may also be uneven. When installing the photovoltaic panel 12, if the bottom is uneven, it may cause the photovoltaic panel 12 to be unbalanced and additional support rods need to be welded. The fixed column 4 and the telescopic column 41 provided by the present invention are used to adjust the balance of the photovoltaic panel 12 during use. By rotating the rotating block 42, the rotating block 42 drives the fourth bevel gear 45 to rotate through the rotating shaft. The fourth bevel gear 45 drives the third bevel gear 44 to rotate. The third bevel gear 44 drives the third lead screw 43 to rotate. The third lead screw 43 drives the telescopic column 41 to move up and down until the four corners of the photovoltaic panel 12 are balanced, realizing the function of adjusting the balance of the photovoltaic panel 12.

[0037] As Figure 8As shown in the figure, four connecting plates 5 are fixedly connected to the side wall of the water trough 35 close to the fixed column 4; two rectangular plates 52 are fixedly connected to each of the two fixed columns 4 close to the water trough 35; a double-headed ball screw 53 is rotatably connected between the two rectangular plates 52, and two L-shaped inserts 51 are threadedly connected to the double-headed ball screw 53, and the L-shaped inserts 51 are inserted into the connecting plates 5; one end of the double-headed ball screw 53 is fixedly connected with a handle 55; two slide bars 54 are fixedly connected between the two rectangular plates 52, and the L-shaped inserts 51 are slidably connected to the slide bars 54.

[0038] The L-shaped insert 51 provided by the present invention is used to fix the water trough 35 during use. By rotating the handle 55, the handle 55 drives the double-headed ball screw 53 to rotate, and the double-headed ball screw 53 drives the L-shaped insert 51 to move to both sides until it is inserted into the connecting plate 5, realizing the installation of the water trough 35. During the movement of the L-shaped insert 51, the L-shaped insert 51 slides on the slide bar 54, and the slide bar 54 limits the L-shaped insert 51 to move in the horizontal direction.

[0039] As Figure 6 and Figure 9 shown, the top of the other two fixed columns 4 is fixedly connected with a top plate 72; the top of the top plate 72 is fixedly connected with an electric push rod 73; the bottom of the bottom plate 1 is fixedly connected with two slide rails 7; a sliding frame 71 is installed below the slide rails 7 through universal wheels; the top of the sliding frame 71 is fixedly connected with a push plate 74, and the output end of the electric push rod 73 is fixedly connected to the push plate 74; two side plates 76 are symmetrically fixedly connected to the side wall of the electric push rod 73; two slide bars 75 are fixedly connected to the push plate 74, and the slide bars 75 are respectively slidably connected to the side plates 76.

[0040] The sliding frame 71 provided by the present invention is used to adjust the angle of the photovoltaic panel 12 during use. When it is monitored by the sensing module 61 and the angle of the photovoltaic panel 12 needs to be adjusted, the electric push rod 73 is energized, the output end of the electric push rod 73 pushes the push plate 74, and the push plate 74 drives the sliding frame 71 to move. The sliding frame 71 moves to different positions, and the universal wheels cooperate with the slide rails 7 to drive one end of the bottom plate 1 and the photovoltaic panel 12 to rotate up or down, realizing the function of adjusting the angle of the photovoltaic panel 12 and improving the energy conversion rate of the solar energy industry; during the movement of the push plate 74, the push plate 74 drives the slide bars 75 to slide on the side plates 76, limiting the push plate 74 to move in a stable state.

[0041] As Figure 1 shown, an installation plate 6 is fixedly connected to one end side wall of the bottom plate 1, and a sensing module 61 is installed on the installation plate 6, including a light sensor, a wind direction sensor and a current sensor.

[0042] The sensor module 61 provided by the present invention is used to monitor light intensity, wind direction and current when in use. By monitoring the light intensity and angle, it is convenient to control the power supply and propulsion amount of the electric push rod 73, so as to adjust the angle of the photovoltaic panel 12; by monitoring the wind direction, the angle of the photovoltaic panel 12 is adjusted to reduce the damage to the photovoltaic panel 12 caused by wind; by monitoring the current, it is convenient to monitor the output current and voltage of the photovoltaic cell assembly. By real-time monitoring the changes in current and voltage, the system can calculate the power generation in real time, and can also promptly discover and resolve faults or abnormal conditions of the photovoltaic assembly according to abnormal changes in current and voltage, thereby ensuring the stable operation of the solar energy industry power generation system.

[0043] Working principle: The technical field of solar energy industry includes the installation of photovoltaic modules. Because dust, sand and other impurities in the air will gradually accumulate on the surface of photovoltaic modules, reducing the transmittance of light, the solar radiation energy received by the photovoltaic modules will decrease, thereby reducing the power generation efficiency, and photovoltaic modules are usually installed above buildings or on open ground, which is inconvenient to clean, thereby reducing the conversion of light energy into electrical energy in the solar energy industry; the cleaning unit provided by the present invention is used to clean the photovoltaic panel 12 when in use, by turning on the motor 23, the motor 23 drives the first screw rod 2 to rotate through the output shaft, and the moving block 22 is driven to reciprocate through the first screw rod 2, and the moving frame 25 and the cleaning brush 252 are driven to reciprocate through the moving block 22, and the surface of the photovoltaic panel 12 is scrubbed by the cleaning brush 252; wherein the first screw rod 2 drives the threaded The sleeve 221 rotates, and the first bevel gear 222 is driven to rotate through the threaded sleeve 221, and the second bevel gear 223 is driven to rotate through the first bevel gear 222, and the rotating shaft and the first rotating wheel 224 are driven to rotate through the second bevel gear 223, and the belt 225 is driven to rotate through the first rotating wheel 224, and the second rotating wheel 226 is driven to rotate through the belt 225, and the connected rotating rod 253, circular gear 251 and cleaning brush 252 are driven to rotate through the second rotating wheel 226. Because a plurality of circular gears 251 are sequentially arranged on one side of the circular gear 251, through the cooperation of the circular gear 251, a plurality of cleaning brushes 252 are all rotated, so that the cleaning brush 252 can rotate at the same time during the movement, so that it is convenient to clean the attachments on the photovoltaic panel 12, solves the problem of inconvenient and quick cleaning of the photovoltaic panel 12, and is beneficial to the conversion of light energy into electrical energy.

[0044] During the rotation of the first lead screw 2, the first lead screw 2 drives the worm 32 to rotate. The worm 32 drives the worm wheel 31 to rotate, and the worm wheel 31 drives the second lead screw 3 to rotate. The second lead screw 3 drives the scraper 33 to reciprocate, and the scraper 33 scrapes the impurities on the water collecting tank 35 to prevent the impurities from blocking the filter holes at the bottom of the water collecting tank 35. When bird droppings or other attachments dry on the photovoltaic panel 12, it is not easy to clean and drop them through the cleaning brush 252, and the photovoltaic panel 12 needs to be rinsed. The filtered water flows into the water tank 381 through the connecting pipe 38. Under the action of the water pump 382, the water in the water tank 381 is conveyed upward through the telescopic pipe 383 to the water delivery pipe 24. The water in the water delivery pipe 24 is ejected through the water spraying pipe 241, and the water spraying pipe 241 is provided with rotating nozzles to facilitate expanding the spraying area and improving the cleaning effect of the photovoltaic panel 12.

[0045] After the rinsing is completed, the fan 261 and the heating wire 262 need to be powered on. The heat of the heating wire 262 is quickly sprayed on the photovoltaic panel 12 by the fan 261 for drying to reduce dust adhesion. If the light intensity is high, drying may not be necessary.

[0046] When adjusting the balance of the photovoltaic panel 12, by rotating the rotary block 42, the rotary block 42 drives the fourth bevel gear 45 to rotate through the rotating shaft. The fourth bevel gear 45 drives the third bevel gear 44 to rotate, and the third bevel gear 44 drives the third lead screw 43 to rotate. The third lead screw 43 drives the telescopic column 41 to move up and down until the four corners of the photovoltaic panel 12 are balanced, realizing the function of adjusting the balance of the photovoltaic panel 12.

[0047] When it is necessary to adjust the angle of the photovoltaic panel 12 through the monitoring of the sensing module 61, the electric push rod 73 is powered on. The output end of the electric push rod 73 pushes the push plate 74, and the push plate 74 drives the sliding frame 71 to move. The sliding frame 71 moves to different positions and drives one end of the bottom plate 1 and the photovoltaic panel 12 to rotate up or down through the cooperation of the universal wheels and the slide rail 7, realizing the function of adjusting the angle of the photovoltaic panel 12 and improving the energy conversion rate of the solar energy industry. During the movement of the push plate 74, the push plate 74 drives the sliding rod 75 to slide on the side plate 76 to limit the push plate 74 to move in a stable state.
