Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic equipment, in particular to an automatic snow removal device for photovoltaic components. Background Art

[0002] Photovoltaic (PV), short for solar photovoltaic power generation, is a power generation system that converts sunlight's radiant energy into electricity. Using semiconductor photovoltaic cells, the photovoltaic effect creates a direct conversion of solar energy into electricity. From an industry chain perspective, the PV industry encompasses upstream links such as silicon material and wafer production, midstream links such as cell and module manufacturing, and downstream links such as the construction and operation of PV power generation systems. It occupies a crucial position within the solar energy industry, representing a rapidly developing sector with significant economic and energy strategic significance.

[0003] Photovoltaic (PV) panels may be covered with snow in winter or in snowy areas, significantly reducing power generation efficiency. Therefore, developing effective snow removal technologies is crucial to improving the energy yield and economic efficiency of PV systems.

[0004] The patent application with publication number CN116938124A applies for photovoltaic module snow removal equipment. By installing a snow removal plate and a snow removal roller on the front side of the frame on the surface of the photovoltaic module, the snow removal plate and the snow removal roller are driven by a crawler-type walking mechanism under the drive of a power mechanism, and the snow removal plate removes floating snow on the surface of the photovoltaic module along the direction of travel; at the same time, the frame cooperates with the edge of the photovoltaic module through a limiting guide assembly, and can move along the surface of the photovoltaic module from one end to the other, thereby completing the snow removal work of the photovoltaic module.

[0005] In the prior art, scraping and knocking are usually used to remove snow from photovoltaic panels. However, due to the gaps between photovoltaic panels, the snow in the gaps cannot be removed well when scraping and knocking is used. In low temperature weather, the remaining snow water can easily freeze into ice, which can easily affect the operating efficiency of the photovoltaic panels. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem that after the snow removal process on the photovoltaic modules is completed, the snow remaining on the photovoltaic modules is easily condensed into ice when it melts in low temperature climate, thereby affecting the operating efficiency of the photovoltaic modules.

[0007] In order to solve the above technical problems, the present invention provides an automatic snow removal device for photovoltaic components, comprising a photovoltaic panel placement area, wherein a plurality of photovoltaic panels are placed in the photovoltaic panel placement area, shift boxes are symmetrically arranged on both sides of the photovoltaic panel placement area, and connecting rods are fixedly installed between the two ends of the two shift boxes, a screw is arranged inside one of the shift boxes, and a polished rod is arranged inside the other shift box, and the outer walls of the screw and the polished rod are both provided with rectangular blocks, a rack is arranged between the two rectangular blocks, a snow removal box is fixedly installed directly below the rack, a motor is fixedly installed at one end of the screw, and a casual assembly is arranged on the outside of the connecting rod, the casual assembly is used to connect and assemble the device with the photovoltaic panel placement area, and a snow removal assembly is arranged inside the snow removal box, and the snow removal assembly is used to clear snow on the photovoltaic panel placement area; By using the portable component on the connecting rod to connect the device with the photovoltaic panel placement area, the device and the photovoltaic panel placement area form a whole. By connecting an external detection device, when the snow stops falling, the motor drives the screw to rotate. When the screw rotates, it drives one of the moment blocks to move, and the other moment block will slide on the light rod, so that the two moment blocks are fed horizontally to drive the snow removal component in the snow removal box at the bottom of the frame to clear the snow on the photovoltaic panel placement area. The motor is used to drive the snow removal component in the snow removal box to move back and forth, so as to achieve the purpose of clearing the snow on the photovoltaic panel placement area.

[0008] In one embodiment of the present invention, the casual assembly includes a limit box, which is slidably connected to the outer wall of the connecting rod, and the upper clamping arm block and the lower clamping arm block are symmetrically slidably connected inside the limit box. A rotating cylinder is fixedly installed on the inner wall of the limit box, and a gear is fixedly installed on the output end of the rotating cylinder. The teeth of the gear are engaged with the teeth on the upper clamping arm block and the lower clamping arm block. During installation, the limit box is moved to the position corresponding to the four corners of the photovoltaic panel placement area, and then the rotating cylinder in the limit box is started to drive the gear to rotate. When the gear rotates, it drives the upper clamping arm block and the lower clamping arm block toward the photovoltaic panel. The upper and lower surfaces of the panel placement area move. When the upper clamping arm block and the lower clamping arm block move to fit the upper and lower surfaces of the photovoltaic panel placement area, the rotating cylinder stops rotating. At this time, the upper clamping arm block and the lower clamping arm block complete the connection between the device and one corner of the photovoltaic panel placement area. Subsequently, the device is connected to the remaining triangles of the photovoltaic panel placement area in sequence according to this step to complete the installation of the device and the photovoltaic panel placement area. The upper clamping arm block and the lower clamping arm block are used to move and clamp the photovoltaic panel placement area for installation, which facilitates installation and disassembly and also makes the device suitable for photovoltaic panel placement areas of different thicknesses.

[0009] In one embodiment of the present invention, a cover is provided on the outside of one of the connecting rods, and the cover is used to protect the motor and the snow removal box to prevent the motor and the snow removal box from being damaged by prolonged exposure to rain and snow. During operation, by providing a cover on the outside of the motor and the snow removal box, the safety of the two can be greatly protected in rainy and snowy weather when not in operation, and the motor and the snow removal box can be prevented from being damaged due to external factors when not in operation.

[0010] In one embodiment of the present invention, the snow removal assembly includes a snow scraper box, a square box is fixedly installed on the inner wall of the snow scraper box, a pneumatic element is fixedly installed on the top of the snow scraper box and the square box, a plurality of vertical shafts are fixedly installed on the top of the pneumatic element, the plurality of vertical shafts are slidably connected to the inner wall of the snow scraper box, a push spring is provided between the plurality of vertical shafts and the inner wall of the snow scraper box, a plurality of hollow shafts are fixedly installed on the top of the inner wall of the snow scraper box, the outer walls of the plurality of vertical shafts are slidably connected to the inner walls of the plurality of hollow shafts respectively, when the motor drives the snow scraper box to move and remove snow through the square block, when the snow scraper box moves to above the photovoltaic panel placement area, due to the light The height of the photovoltaic panels arranged in the photovoltaic panel placement area is lower than the normal height of the photovoltaic panel placement area. The push spring in the snow removal box will push the air pressure element to drive the hollow shaft to move downward in the vertical axis. The snow scraper box and the square box will be driven by the air pressure element to move downward to fit the surface of the photovoltaic panels in the photovoltaic panel placement area. Then, the motor drives the snow removal box to move back and forth continuously, thereby pushing the snow on the photovoltaic panels in the photovoltaic panel placement area to the outside of the photovoltaic panel placement area for snow removal operations. The elastic thrust of the push spring drives the snow scraper box to fit the surface of the photovoltaic panels in the photovoltaic panel placement area, and can operate on photovoltaic panels of different heights.

[0011] In one embodiment of the present invention, snow scrapers are symmetrically arranged on both sides of the bottom of the snow scraper box. When the snow scraper box is attached to the surface of the photovoltaic panel in the photovoltaic panel placement area, the snow removal box is driven to move by the motor, so that the snow scrapers at the bottom of the snow scraper box scrape and push the snow on the photovoltaic panel to achieve the purpose of snow removal. It should be noted here that a rubber protective cover is provided on the outside of the snow scraper, and the snow scrapers are symmetrically arranged at the bottom of the snow scraper box, so as to achieve the purpose of reciprocating removal of snow in the photovoltaic panel placement area.

[0012] In one embodiment of the present invention, a hair dryer is provided inside the snow scraper box, and heaters are symmetrically fixedly installed on the inner wall of the snow scraper box, and a heat pipe is fixedly installed between the two heaters. When the snow scraper box drives the snow scraper to scrape and push the photovoltaic panels in the photovoltaic panel placement area, the heater in the snow scraper box heats the heat pipe, and then the hair dryer blows the heat pipe. When the snow scraper is pushing the snow, the hair dryer and heater on the opposite side operate, thereby performing a heat blowing operation on the surface of the photovoltaic panels in the photovoltaic panel placement area after pushing the snow, and melting the residual snow on the photovoltaic panels in the photovoltaic panel placement area, thereby melting ice and water.

[0013] In one embodiment of the present invention, air outlets are symmetrically provided at the bottom of the snow scraper box. The two air outlets are respectively arranged directly above the two snow scrapers. Both air outlets are opened as oblique blowing outlets. When the snow scrapers push the snow, the blower on the opposite side blows out hot air. Since the shape of the air outlet is an oblique blowing outlet, the hot air will be blown out from the air outlet to the surface of the photovoltaic panel in the photovoltaic panel placement area, and the remaining snow will be melted by heat.

[0014] In one embodiment of the present invention, a plurality of air pressure flow tubes are fixedly installed at the bottom of the air pressure element, and one end of the plurality of air pressure flow tubes passes through the top of the rectangular box and is arranged on the square inside the rectangular box. The inner wall of the rectangular box is slidably connected with a salt water pressure plate. The bottom of the salt water pressure plate and the bottom of the rectangular box are between the bottom of the salt water pressure plate and the bottom of the rectangular box. Salt water is placed inside the salt water. When the snow scraper pushes the snow in the photovoltaic panel placement area, the air pressure element in the snow scraper box squeezes the salt water pressure plate in the rectangular box through the air pressure flow tube. When the salt water pressure plate is under pressure, the salt water placed between the bottom of the salt water pressure plate and the bottom of the rectangular box will be pressed out of the rectangular box. The salt water will flow out and eventually remain on the surface of the photovoltaic panels in the photovoltaic panel placement area. Since salt will lower the freezing point of water after dissolving in water, spreading salt water on the surface of the photovoltaic panels can effectively prevent the photovoltaic panels from freezing. This prevents the hot wind from melting the remaining snow into water. In low temperature climates, the water will freeze on the surface of the photovoltaic panels. The motor will then drive the snow scraper to scrape back and forth, and the hot air blown out from the air outlet will blow back and forth on the photovoltaic panels. The salt water effectively blocks the water, and the salt water mixture accumulated on the photovoltaic panels will be continuously blown by the hot wind until it evaporates, thereby achieving ice and snow prevention in the photovoltaic panel placement area.

[0015] In one embodiment of the present invention, the inner wall of the rectangular box is symmetrically fixed with strips, and the bottom of the inner wall of the rectangular box is symmetrically provided with water-blocking plates, and the two water-blocking plates are slidably connected to the bottoms of the two strips respectively. Two sets of limited-slip shafts are symmetrically provided at the bottom of the inner wall of the rectangular box, and the two sets of limited-slip shafts are slidably connected to the inner walls of the two water-blocking plates respectively. A set of return springs is provided between the two water-blocking plates and the inner wall of the rectangular box, and the two sets of return springs are respectively provided on the outside of the two sets of limited-slip shafts. A brine leak is opened at the bottom of the rectangular box, and the bottoms of the two water-blocking plates are placed directly above the brine leak. When the brine pressure plate is pressed down, the brine pressure plate pushes the brine to expel the water-blocking plates and squeeze the return springs to slide on the limited-slip shafts, and the two water-blocking plates will move to both sides, and the brine leak located at the bottom of the two water-blocking plates will open. Through the continuous pressure of the brine pressure plate, the brine will be pressurized and drip out of the brine leak, so that the brine placed in the rectangular box flows out of the rectangular box, thereby controlling the flow of brine.

[0016] In one embodiment of the present invention, the bottom of the snow scraper box is rotatably connected to a salt-coated shaft. When brine flows out from the brine leak, the brine will fall on the surface of the salt-coated shaft. Then, the snow scraper box is driven by a motor to continuously move on the photovoltaic module, and the salt-coated shaft will roll on the photovoltaic module. The brine falling on the salt-coated shaft will be stained by the photovoltaic module through the rolling of the salt-coated shaft, so that the brine covers the scraped photovoltaic module, preventing the melted snow from freezing due to the hot wind. Finally, the brine mixture on the photovoltaic module is evaporated by the hot air blown back and forth from the air outlet, thereby achieving the effect of snow removal and anti-icing.

[0017] The above technical solution of the present invention has the following advantages over the prior art: The present invention describes an automatic snow removal device for photovoltaic modules. When a snow scraper box drives a snow scraper to scrape and push the photovoltaic panels in the photovoltaic panel placement area, the heater in the snow scraper box heats the heat conduction tube, and then the blower blows the heat conduction tube. When the snow scraper is pushing the snow, the blower and heater on the opposite side operate, thereby performing a heat blowing operation on the surface of the photovoltaic panels in the photovoltaic panel placement area after the snow is pushed, melting the residual snow on the photovoltaic panels in the photovoltaic panel placement area, thereby melting ice and turning water.

[0018] The present invention relates to an automatic snow removal device for photovoltaic modules. When a snow scraper pushes the accumulated snow in the photovoltaic panel placement area, a pneumatic element squeezes the brine pressure plate in a rectangular box. The brine placed between the bottom of the brine pressure plate and the bottom of the rectangular box is pressed and falls from the rectangular box onto the surface of the salt-coated shaft. Subsequently, the snow scraper box is driven by a motor to continuously move on the photovoltaic module. The salt-coated shaft rolls on the photovoltaic module. The brine dropped on the salt-coated shaft is stained by the rolling of the salt-coated shaft, thereby covering the scraped photovoltaic module with brine, preventing the melted snow from freezing due to the hot wind. Finally, the brine mixture on the photovoltaic module is evaporated by the hot wind blown back and forth from the air outlet, thereby achieving the effect of snow removal and anti-icing.

[0019] The automatic snow removal device for photovoltaic components described in the present invention drives the gear to rotate by rotating the cylinder. When the gear rotates, it drives the upper clamping arm block and the lower clamping arm block to move toward the upper and lower surfaces of the photovoltaic panel placement area. When the upper clamping arm block and the lower clamping arm block move to fit the upper and lower surfaces of the photovoltaic panel placement area, the connection between the device and one corner of the photovoltaic panel placement area is completed. Subsequently, the device is connected to the remaining triangles of the photovoltaic panel placement area in sequence according to this step to complete the installation of the device and the photovoltaic panel placement area. The upper clamping arm block and the lower clamping arm block are used to move and clamp the photovoltaic panel placement area for installation, which facilitates installation and disassembly and also makes the device suitable for photovoltaic panel placement areas of different thicknesses. By moving the portable component on the connecting rod, it can be adapted to photovoltaic panel placement areas of different widths.

[0020] The automatic snow removal device for photovoltaic modules described in the present invention uses a motor to drive a snow removal box to move and remove snow. When the snow removal box moves above the photovoltaic panel placement area, the push spring in the snow removal box pushes the snow scraper box and the matrix box to move down and fit the photovoltaic panel surface in the photovoltaic panel placement area. Then, the motor drives the snow removal box to move back and forth continuously, thereby pushing the snow accumulated on the photovoltaic panels in the photovoltaic panel placement area to the outside of the photovoltaic panel placement area to perform snow removal operations. The elastic thrust of the push spring drives the snow scraper box to fit the photovoltaic panel surface in the photovoltaic panel placement area, and operations can be performed on photovoltaic panels of different heights.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0025] like Figures 1 to 11 As shown, an automatic snow removal device for photovoltaic components of the present invention includes a photovoltaic panel placement area 1, in which a plurality of photovoltaic panels are placed, shift boxes 3 are symmetrically arranged on both sides of the photovoltaic panel placement area 1, and connecting rods 4 are fixedly installed between the two ends of the two shift boxes 3, a screw 6 is arranged inside one of the shift boxes 3, and a polished rod 7 is arranged inside the other shift box 3, and the outer walls of the screw 6 and the polished rod 7 are both provided with rectangular blocks 9, and a rack 8 is provided between the two rectangular blocks 9, and a snow removal box 15 is fixedly installed just below the rack 8, and a motor 5 is fixedly installed at one end of the screw 6, and a casual assembly is provided on the outside of the connecting rod 4, and the casual assembly is used to connect and assemble the device with the photovoltaic panel placement area 1, and a snow removal assembly is provided inside the snow removal box 15, and the snow removal assembly is used to clear snow on the photovoltaic panel placement area 1; In the prior art, scraping and knocking are usually used to remove snow from photovoltaic modules. However, due to the gaps between photovoltaic modules, the snow in the gaps cannot be removed properly when scraping and knocking is used. In cold weather, the remaining snow water easily freezes into ice, which can easily affect the operating efficiency of the photovoltaic modules. By using the portable assembly on the connecting rod 4 to connect the device to the photovoltaic panel placement area 1, the device and the photovoltaic panel placement area 1 form a whole. By connecting an external detection device, when the snow falls, the motor 5 drives the screw 6 to rotate. When the screw 6 rotates, it drives one of the moment blocks 9 to move, and the other moment block 9 will slide on the light rod 7. Thus, the two moment blocks 9 are fed horizontally to drive the snow removal assembly in the snow removal box 15 at the bottom of the frame rod 8 to clear the snow on the photovoltaic panel placement area 1. By using the motor 5 to drive the snow removal assembly in the snow removal box 15 The reciprocating movement can clear the snow on the photovoltaic panel placement area 1, thereby solving the problem in the prior art that due to the presence of gaps between photovoltaic modules, the snow in the gaps cannot be well cleared when scraping and knocking the snow, and the residual snow water in low temperature weather can easily freeze into ice, which can easily affect the operating efficiency of the photovoltaic modules. It should be noted here that the casual component provided on the connecting rod 4 is in a sliding connection with the connecting rod 4. By moving the casual component on the connecting rod 4, it can be adapted to photovoltaic panel placement areas 1 of different widths.

[0026] like Figures 4 and 5 As shown, in one embodiment of the present invention, the casual wear assembly includes a limit box 11, which is slidably connected to the outer wall of the connecting rod 4. The upper clamping arm block 10 and the lower clamping arm block 12 are symmetrically slidably connected inside the limit box 11. A rotary cylinder 14 is fixedly installed on the inner wall of the limit box 11, and a gear 13 is fixedly installed on the output end of the rotary cylinder 14. The teeth of the gear 13 mesh with the teeth on the upper clamping arm block 10 and the lower clamping arm block 12; During installation, the limit box 11 is moved to the position corresponding to the four corners of the photovoltaic panel placement area 1, and then the rotating cylinder 14 in the limit box 11 is started to drive the gear 13 to rotate. When the gear 13 rotates, it drives the upper clamping arm block 10 and the lower clamping arm block 12 to move toward the upper and lower surfaces of the photovoltaic panel placement area 1. When the upper clamping arm block 10 and the lower clamping arm block 12 move to fit the upper and lower surfaces of the photovoltaic panel placement area 1, the rotating cylinder 14 stops rotating. At this time, the upper clamping arm block 10 and the lower clamping arm block 12 complete the connection between the device and one corner of the photovoltaic panel placement area 1. Subsequently, the device is connected to the remaining triangles of the photovoltaic panel placement area 1 in this step to complete the installation of the device and the photovoltaic panel placement area 1. The upper clamping arm block 10 and the lower clamping arm block 12 are used to move and clamp the photovoltaic panel placement area 1 for installation, which is convenient for installation and disassembly and can also make the device suitable for photovoltaic panel placement areas 1 of different thicknesses.

[0027] like Figures 1 to 3 As shown, in one embodiment of the present invention, a cover 2 is provided on the outside of one of the connecting rods 4. The cover 2 is used to protect the motor 5 and the snow removal box 15 to prevent the motor 5 and the snow removal box 15 from being damaged by prolonged exposure to rain and snow. During operation, by providing a cover 2 outside the motor 5 and the snow removal box 15, the safety of the two can be greatly protected in rainy and snowy weather when not in operation, and the motor 5 and the snow removal box 15 can be prevented from being damaged due to external factors when not in operation.

[0028] like Figures 6 to 11 As shown, in one embodiment of the present invention, the snow removal assembly includes a snow scraper box 19, a rectangular box 20 is fixedly installed on the inner wall of the snow scraper box 19, a pneumatic element 18 is fixedly installed on the top of the snow scraper box 19 and the rectangular box 20, a plurality of vertical shafts 34 are fixedly installed on the top of the pneumatic element 18, the plurality of vertical shafts 34 are slidably connected to the inner wall of the snow removal box 15, a pusher spring 16 is provided between the plurality of vertical shafts 34 and the inner wall of the snow removal box 15, a plurality of hollow shafts 17 are fixedly installed on the top of the inner wall of the snow removal box 15, and the outer walls of the plurality of vertical shafts 34 are slidably connected to the inner walls of the plurality of hollow shafts 17 respectively; When the motor 5 drives the snow removal box 15 to move and remove snow through the moment block 9, when the snow removal box 15 moves to the top of the photovoltaic panel placement area 1, since the height of the photovoltaic panels arranged in the photovoltaic panel placement area 1 is lower than the normal height of the photovoltaic panel placement area 1, the pusher spring 16 in the snow removal box 15 will push the air pressure element 18 to drive the hollow shaft 17 to move downward in the vertical shaft 34, and the snow scraping box 19 and the moment box 20 will be driven by the air pressure element 18 to move downward to fit the surface of the photovoltaic panel in the photovoltaic panel placement area 1, and then the snow removal box 15 will be driven by the motor 5. The snow scraper box 19 is driven by the elastic thrust of the push spring 16 to fit the surface of the photovoltaic panels in the photovoltaic panel placement area 1, and can operate on photovoltaic panels of different heights. It should be noted here that the initial position of the snow removal box 15 should be placed at the edge of the photovoltaic panel placement area 1, and the laying height of the photovoltaic panels set in the photovoltaic panel placement area 1 should be in a regular state. A rubber protective cover is provided at the bottom of the snow scraper box 19.

[0029] like Figures 8 and 9 As shown, in one embodiment of the present invention, snow scrapers 22 are symmetrically provided on both sides of the bottom of the snow scraper box 19; When the snow scraper box 19 is attached to the surface of the photovoltaic panel in the photovoltaic panel placement area 1, the motor 5 drives the snow removal box 15 to move, so that the snow scraper 22 at the bottom of the snow scraper box 19 scrapes and pushes the snow on the photovoltaic panel to achieve the purpose of snow removal. It should be noted here that a rubber protective cover is provided on the outside of the snow scraper 22, and the snow scraper 22 is symmetrically arranged at the bottom of the snow scraper box 19, thereby achieving the purpose of reciprocatingly clearing the snow in the photovoltaic panel placement area 1.

[0030] like Figures 9 and 10As shown, in one embodiment of the present invention, a blower 25 is provided inside the snow scraper box 19, heaters 24 are symmetrically fixedly installed on the inner wall of the snow scraper box 19, and a heat pipe 26 is fixedly installed between the two heaters 24; When the snow scraper box 19 drives the snow scraper 22 to scrape and push the photovoltaic panels in the photovoltaic panel placement area 1, the heater 24 in the snow scraper box 19 heats the heat conduction pipe 26, and then the blower 25 blows the heat conduction pipe 26. When the snow scraper 22 is pushing snow, the blower 25 and the heater 24 on the opposite side operate, thereby performing a heat blowing operation on the surface of the photovoltaic panels in the photovoltaic panel placement area 1 after pushing the snow, and melting the residual snow on the photovoltaic panels in the photovoltaic panel placement area 1, which has the effect of melting ice and turning into water. It should be noted here that the wind temperature emitted from the heat conduction pipe 26 blown by the blower 25 needs to be actually measured and calculated.

[0031] like Figures 8 to 10 As shown, in one embodiment of the present invention, the bottom of the snow scraper box 19 is symmetrically provided with air outlets 23, and the two air outlets 23 are respectively provided directly above the two snow scrapers 22, and the two air outlets 23 are both provided as oblique blowing ports; When the snow scraper 22 pushes the snow, the blower 25 on the opposite side blows out hot air. Since the shape of the air outlet 23 is an oblique blowing shape, the hot air will be blown out from the air outlet 23 to the surface of the photovoltaic panel in the photovoltaic panel placement area 1 to perform thermal melting operations on the remaining snow. It should be noted here that the opening slope of the air outlet 23 needs to be calculated based on actual measurements.

[0032] like Figures 9 to 11 As shown, in one embodiment of the present invention, a plurality of air pressure flow tubes 27 are fixedly installed at the bottom of the air pressure element 18, one end of each of the plurality of air pressure flow tubes 27 passes through the top of the rectangular box 20 and is arranged on the square inside the rectangular box 20, and a brine pressure plate 28 is slidably connected to the inner wall of the rectangular box 20. The bottom of the brine pressure plate 28 and the bottom of the rectangular box 20 are between the brine placement area, and brine is placed inside. When the snow scraper 22 pushes the snow in the photovoltaic panel placement area 1, the air pressure element 18 in the snow scraper box 19 squeezes the salt water pressure plate 28 in the rectangular box 20 through the air pressure flow tube 27. When the salt water pressure plate 28 is under pressure, the salt water placed between the bottom of the salt water pressure plate 28 and the bottom of the rectangular box 20 will be pressed out of the rectangular box 20 and finally retained on the surface of the photovoltaic panel in the photovoltaic panel placement area 1. Since salt will lower the freezing point of water after dissolving in water, laying salt water on the surface of the photovoltaic panel can effectively prevent the photovoltaic panel from freezing and prevent ice from forming. When the hot wind melts the remaining snow into water, in low temperature climates, the water freezes on the surface of the photovoltaic panel, and then the motor 5 drives the snow scraper 22 to scrape back and forth, and the hot air blown out from the air outlet 23 will blow back and forth on the photovoltaic panel. The brine effectively blocks the water, and the brine mixture accumulated on the photovoltaic panel will be continuously blown by the hot wind until it evaporates, thereby achieving ice and snow removal in the photovoltaic panel placement area 1. It should be noted here that the salt content of the brine placed in the matrix box 20 needs to be actually measured, and a sealing ring is provided on the edge of the brine pressure plate 28.

[0033] like Figures 9 to 11 As shown, in one embodiment of the present invention, strips 30 are symmetrically fixedly installed on the inner wall of the rectangular box 20, and water blocking plates 29 are symmetrically provided on the bottom of the inner wall of the rectangular box 20. The two water blocking plates 29 are slidably connected to the bottoms of the two strips 30 respectively. Two sets of limited-slip shafts 32 are symmetrically provided on the bottom of the inner wall of the rectangular box 20. The two sets of limited-slip shafts 32 are slidably connected to the inner walls of the two water blocking plates 29 respectively. A set of return springs 31 is provided between the two water blocking plates 29 and the inner wall of the rectangular box 20. The two sets of return springs 31 are respectively provided on the outside of the two sets of limited-slip shafts 32. A brine leak 33 is opened at the bottom of the rectangular box 20, and the bottoms of the two water blocking plates 29 are placed directly above the brine leak 33. When the brine pressure plate 28 is pressed down, the brine pressure plate 28 pushes the brine to discharge the water blocking plate 29 and squeeze the return spring 31 to slide on the limited sliding shaft 32, and the two water blocking plates 29 will move to both sides, and the brine leak 33 located at the bottom of the two water blocking plates 29 will open. Through the continuous pressure of the brine pressure plate 28, the brine will be pressurized and drip out of the brine leak 33, so that the brine placed in the rectangular box 20 flows out of the rectangular box 20, which plays a role in controlling the flow of brine. It should be noted here that the opening specifications of the brine leak 33 need to be actually measured and calculated, and the bottom of the two water blocking plates 29 are provided with sealing colloid.

[0034] like Figures 9 to 11 As shown, in one embodiment of the present invention, the bottom of the snow scraper box 19 is rotatably connected to a salt coating shaft 21; When the brine flows out from the brine leak 33, the outflowing brine will fall on the surface of the salt coating shaft 21, and then the motor 5 drives the snow scraper box 19 to continuously move on the photovoltaic module, and the salt coating shaft 21 will roll on the photovoltaic module. The brine falling on the salt coating shaft 21 will be stained by the rolling of the salt coating shaft 21, so that the brine covers the scraped photovoltaic module, preventing the snow melted by the hot wind from freezing. Finally, the brine mixture on the photovoltaic module is evaporated by the hot air blown back and forth from the air outlet 23, thereby achieving the effect of snow removal and anti-icing.

[0035] Working principle: By using the casual assembly on the connecting rod 4 to connect the device to the photovoltaic panel placement area 1, the device and the photovoltaic panel placement area 1 form a whole. By connecting an external detection device, when the snow falls, the motor 5 drives the screw 6 to rotate. When the screw 6 rotates, it drives one of the moment blocks 9 to move, and the other moment block 9 will slide on the light rod 7. The two moment blocks 9 are fed horizontally to drive the snow removal assembly in the snow removal box 15 at the bottom of the frame rod 8 to clear the snow on the photovoltaic panel placement area 1. By using the motor 5 to drive the snow removal assembly in the snow removal box 15 The reciprocating movement of the snow assembly enables the snow on the photovoltaic panel placement area 1 to be cleared, thereby solving the problem in the prior art that due to the gaps between the photovoltaic panels, the snow in the gaps cannot be well cleared when the snow is scraped by knocking, and the residual snow water in low temperature weather can easily freeze into ice, which can easily affect the operating efficiency of the photovoltaic panels. It should be noted that the casual assembly provided on the connecting rod 4 is in a sliding connection with the connecting rod 4. By moving the casual assembly on the connecting rod 4, it can be adapted to photovoltaic panel placement areas 1 of different widths; During installation, the limit box 11 is moved to the position corresponding to the four corners of the photovoltaic panel placement area 1, and then the rotating cylinder 14 in the limit box 11 is started to drive the gear 13 to rotate. When the gear 13 rotates, it drives the upper clamping arm block 10 and the lower clamping arm block 12 to move toward the upper and lower surfaces of the photovoltaic panel placement area 1. When the upper clamping arm block 10 and the lower clamping arm block 12 move to fit the upper and lower surfaces of the photovoltaic panel placement area 1, the rotating cylinder 14 stops rotating. At this time, the upper clamping arm block 10 and the lower clamping arm block 12 complete the connection between the device and one corner of the photovoltaic panel placement area 1, and then the device is connected to the remaining triangles of the photovoltaic panel placement area 1 in this step to complete the installation of the device and the photovoltaic panel placement area 1. The upper clamping arm block 10 and the lower clamping arm block 12 are used to move and clamp the photovoltaic panel placement area 1 for installation, which is convenient for installation and disassembly and can also make the device suitable for photovoltaic panel placement areas 1 of different thicknesses; When working, by providing a cover 2 outside the motor 5 and the snow removal box 15, the safety of the two can be greatly protected in rainy and snowy weather when not working, and the motor 5 and the snow removal box 15 can be prevented from being damaged by external factors when not working; When the motor 5 drives the snow removal box 15 to move and remove snow through the moment block 9, when the snow removal box 15 moves above the photovoltaic panel placement area 1, since the height of the photovoltaic panels arranged in the photovoltaic panel placement area 1 is lower than the normal height of the photovoltaic panel placement area 1, the pusher spring 16 in the snow removal box 15 will push the air pressure element 18 to drive the hollow shaft 17 to move downward in the vertical shaft 34, and the snow scraper box 19 and the moment box 20 will be driven by the air pressure element 18 to move downward to fit the surface of the photovoltaic panels in the photovoltaic panel placement area 1, and then the motor 5 drives the snow removal box 15 to move back and forth continuously, thereby pushing the snow on the photovoltaic panels in the photovoltaic panel placement area 1 to the outside of the photovoltaic panel placement area 1 to perform snow removal operations. The elastic thrust of the pusher spring 16 drives the snow scraper box 19 to fit the surface of the photovoltaic panels in the photovoltaic panel placement area 1, so that operations can be performed on photovoltaic panels of different heights. When the snow scraper box 19 is attached to the surface of the photovoltaic panel in the photovoltaic panel placement area 1, the motor 5 drives the snow removal box 15 to move, so that the snow scraper 22 at the bottom of the snow scraper box 19 scrapes and pushes the snow on the photovoltaic panel to achieve the snow removal effect. It should be noted that the snow scraper 22 is provided with a rubber protective cover on the outside. The snow scraper 22 is symmetrically arranged at the bottom of the snow scraper box 19, thereby achieving the reciprocating removal of snow in the photovoltaic panel placement area 1. When the snow scraper box 19 drives the snow scraper 22 to scrape and push the photovoltaic panels in the photovoltaic panel placement area 1, the heater 24 in the snow scraper box 19 heats the heat conducting pipe 26, and then the blower 25 blows the heat conducting pipe 26. When the snow scraper 22 pushes the snow, the blower 25 and the heater 24 on the opposite side work, thereby performing a heat blowing operation on the surface of the photovoltaic panels in the photovoltaic panel placement area 1 after the snow is pushed, and melting the residual snow on the photovoltaic panels in the photovoltaic panel placement area 1, thereby playing the role of melting ice and turning into water; When the snow scraper 22 is scraping the snow, the blower 25 on the opposite side blows out hot air. Since the air outlet 23 is in the shape of an oblique blowing port, the hot air will be blown out from the air outlet 23 to the surface of the photovoltaic panels in the photovoltaic panel placement area 1, melting the remaining snow. When the snow scraper 22 pushes the accumulated snow in the photovoltaic panel placement area 1, the air pressure element 18 in the snow scraper box 19 squeezes the salt water pressure plate 28 in the rectangular box 20 through the air pressure flow tube 27. When the salt water pressure plate 28 is under pressure, the salt water placed between the bottom of the salt water pressure plate 28 and the bottom of the rectangular box 20 will be pressed out of the rectangular box 20 and finally retained on the surface of the photovoltaic panel in the photovoltaic panel placement area 1. Since salt will lower the freezing point of water after dissolving in water, laying salt water on the surface of the photovoltaic panel can effectively prevent the photovoltaic panel from freezing, and prevent the water from freezing on the surface of the photovoltaic panel in low temperature climate after the hot wind melts the remaining snow into water. Then, the motor 5 drives the snow scraper 22 to scrape and push back and forth, and the hot air blown out from the air outlet 23 will blow back and forth on the photovoltaic panel. The salt water effectively blocks the water, and the salt water mixture accumulated on the photovoltaic panel will be continuously blown by the hot wind until it evaporates, thereby achieving ice and snow prevention in the photovoltaic panel placement area 1. When the brine pressure plate 28 is pressed down, the brine pressure plate 28 pushes the brine expulsion water blocking plate 29 to squeeze the return spring 31 to slide on the limited sliding shaft 32, and the two water blocking plates 29 will move to both sides, and the brine leakage holes 33 located at the bottom of the two water blocking plates 29 will open. With the continuous pressure of the brine pressure plate 28, the brine will be pressurized and drip out of the brine leakage holes 33, so that the brine in the rectangular box 20 flows out of the rectangular box 20, which plays a role in controlling the flow of brine. When the brine flows out from the brine leak 33, the outflowing brine will fall on the surface of the salt coating shaft 21, and then the motor 5 drives the snow scraper box 19 to continuously move on the photovoltaic module, and the salt coating shaft 21 will roll on the photovoltaic module. The brine falling on the salt coating shaft 21 will be stained by the rolling of the salt coating shaft 21, so that the brine covers the scraped photovoltaic module, preventing the snow melted by the hot wind from freezing. Finally, the brine mixture on the photovoltaic module is evaporated by the hot air blown back and forth from the air outlet 23, thereby achieving the effect of snow removal and anti-icing.
