Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel protection technology, specifically to a protective device for solar photovoltaic panels in extremely cold rain and snow conditions. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. It mainly consists of three parts: solar panels, a controller, and an inverter, with the main components being electronic devices. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. These modules, along with components such as power controllers, form a photovoltaic power generation device. In photovoltaic power generation, the solar panel is the most crucial component.

[0003] Existing extreme cold and snow protection devices for solar photovoltaic panels include a support panel and a photovoltaic panel. A support block is fixedly installed on the upper surface of the support panel, and a telescopic plate and a fixed plate are also located on the upper surface of the support panel. A flipping component is installed on the side of the support block to extend and retract the telescopic plate, simultaneously flipping the telescopic plate and the fixed plate to cover the photovoltaic panel. The flipping component includes a mounting plate and a transmission module. A toothed plate is fixedly connected to the side of the telescopic plate near the support block, and a gear corresponding to the toothed plate is fixedly installed on the side of the mounting plate away from the support block. In the aforementioned application, the flipping component causes the telescopic plate to extend from the bottom of the fixed plate, and with the cooperation of a baffle, the photovoltaic panel is protected under the telescopic plate and the fixed plate, preventing damage to the photovoltaic panel from severe weather. However, when using a cleaning plate for snow removal in existing extreme cold and snow protection devices for solar photovoltaic panels, the use of a cleaning plate on only one side results in poor cleaning effectiveness for the device, thus affecting the overall protective effect of the device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a protective device for solar photovoltaic panels in extremely cold weather, rain, and snow, solving the problems mentioned in the background section. To achieve the above objectives, this invention is implemented through the following technical solution: a protective device for solar photovoltaic panels in extremely cold weather, rain, and snow, comprising a shelf, a photovoltaic panel body mounted on the top of the shelf, and a protective plate driven by a servo motor rotatably connected to the top of the shelf;

[0005] A base is fixedly connected to the top of the protective plate. A reciprocating screw driven by a servo motor is rotatably connected inside the base. A sliding block is threadedly connected to the outer side of the reciprocating screw. A cleaning plate is rotatably connected to the side of the sliding block. A fixing rod is fixedly connected to the side of the base. A limiting rod is fixedly connected to the side of the fixing rod. A limiting plate is rotatably connected to the bottom of the limiting rod via a torsion spring. A gravity iron column is installed inside the cleaning plate. A magnetic adsorption block is installed on the bottom inner wall of the protective plate. A spraying assembly for spraying salt water solution is installed on the top of the protective plate. A limiting assembly for limiting the spraying frequency of the salt water solution is also installed on the top of the protective plate. Through the arrangement of these components, the device uses both ends of the cleaning plate to perform corresponding snow removal operations sequentially, improving the snow removal effect and thus enhancing the overall protective effect of the device.

[0006] Preferably, the sliding block is located inside the storage seat and is in a sliding connection with the storage seat.

[0007] Preferably, there are two cleaning plates, which are symmetrically distributed about the sliding block.

[0008] Preferably, the spraying assembly includes a second fixed rod, a first bevel gear connected to the outer side of the reciprocating screw, a through-type rotating shaft rotatably connected to the side of the second fixed rod, a second bevel gear fixedly connected to the bottom of the rotating shaft, a first sprocket fixedly connected to the outer side of the rotating shaft, a chain mounted on the outer side of the first sprocket, a liquid pump mounted on the side of the shelf, a pipe fixedly connected to the side of the first fixed rod, a hose connected between the pipe and the liquid pump, a pipe joint rotatably connected to the bottom of the pipe, a second sprocket fixedly connected to the outer side of the pipe joint, and a nozzle fixedly connected to the bottom of the pipe joint. By configuring the spraying assembly, the brine solution can be sprayed rotatably onto the top of the protective plate, increasing the coverage area of ​​the brine solution on the top of the protective plate and further improving the snow removal effect of the device.

[0009] Preferably, the second bevel gear is located at the top of the first bevel gear and is in mesh with the first bevel gear.

[0010] Preferably, the end of the chain furthest from the first sprocket is fitted to the outer side of the second sprocket.

[0011] Preferably, the limiting component includes a hydraulic chamber, one end of which is slidably connected to a force-bearing rod, and the other end of which is slidably connected to an arc-shaped rod. A spring is fitted to the side of the force-bearing rod. A through-hole rotating block is rotatably connected inside the pipe, a force-bearing plate is fixedly connected to the outside of the rotating block, and a block is fixedly connected to the bottom of the rotating block. By setting up the limiting component, salt water solution can be intermittently sprayed onto the top of the protective plate, improving snow removal efficiency while reducing waste of salt water solution, making the device easier to use.

[0012] Preferably, the force-bearing plate is located on the side of the arc-shaped rod and is fixed to the arc-shaped rod.

[0013] This invention provides a protective device for solar photovoltaic panels in extremely cold weather, rain, and snow. It has the following beneficial effects:

[0014] (1) The solar photovoltaic panel uses an extreme cold rain and snow protection device. It uses a reciprocating screw driven by a servo motor, along with a placement seat, sliding block, fixed rod one, limiting rod, torsion spring, limiting plate, gravity iron column and magnetic adsorption block, so that the two ends of the cleaning plate of the device can perform corresponding snow removal operations in sequence, which improves the snow removal effect of the device and thus improves the overall protection effect of the device.

[0015] (2) The solar photovoltaic panel is protected against extreme cold rain and snow. When the reciprocating screw rotates, it works with the fixed rod 2, bevel gear 1, rotating shaft, bevel gear 2, sprocket 1, chain, liquid pump, pipe, hose, pipe joint, sprocket 2 and nozzle to spray the salt water solution onto the top of the protective panel, which increases the coverage of the salt water solution on the top of the protective panel and further improves the snow removal effect of the device.

[0016] (3) The solar photovoltaic panel is used for extreme cold rain and snow protection device. When the sliding block moves back and forth in the horizontal direction and moves towards the force rod, it can intermittently spray salt water solution onto the top of the protective plate in conjunction with the hydraulic chamber, arc rod, spring, rotating block, force plate and blocking block. This improves the snow removal effect while reducing the waste of salt water solution, making the device easier to use. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1, please refer to Figures 1-4 A protective device for solar photovoltaic panels in extreme cold rain and snow includes a shelf 100, a photovoltaic panel body 200 mounted on the top of the shelf 100, and a protective plate 300 driven by a servo motor rotatably connected to the top of the shelf 100.

[0031] A shelf 401 is fixedly connected to the top of the protective plate 300. A reciprocating screw 402 driven by a servo motor is rotatably connected inside the shelf 401. A sliding block 403 is threadedly connected to the outer side of the reciprocating screw 402. The sliding block 403 is located inside the shelf 401 and is in a sliding connection with it. A cleaning plate 404 is rotatably connected to the side of the sliding block 403. Two cleaning plates 404 are provided, symmetrically distributed about the sliding block 403. When the reciprocating screw 402 driven by the servo motor is activated, it begins to rotate. Because the sliding block 403, threaded onto the reciprocating screw 402, is restricted by the shelf 401, it reciprocates horizontally. The sliding block 403 then drives the cleaning plate 404, which is rotatably connected to it, to reciprocate horizontally.

[0032] A fixing rod 405 is fixedly connected to the side of the storage seat 401. A limiting rod 406 is fixedly connected to the side of the fixing rod 405. A limiting plate 408 is rotatably connected to the bottom of the limiting rod 406 via a torsion spring 407. A gravity iron column 409 is installed inside the cleaning plate 404. A magnetic adsorption block 410 is installed on the bottom side of the inner wall of the protective plate 300. When the cleaning plate 404 moves to the limiting rod 406, it is compressed by the limiting plate 408. Because the limiting plate 408 is restricted by the limiting rod 406, it cannot rotate around the torsion spring 407. This causes the cleaning plate 404 to rotate under the action of the limiting plate 408, and simultaneously, due to its own inertia, it rotates by more than 90 degrees but less than 270 degrees. The gravity iron column 409 inside the cleaning plate 404 then moves to the other side under the attraction of the magnetic adsorption block 410, thus maintaining the cleaning plate 404 in a state of 180-degree rotation. At this time, the other side of the cleaning plate 404... The cleaning plate 404 rotates to a position close to the top of the protective plate 300. As the reciprocating screw 402 continues to rotate, causing the sliding block 403 to reset, the cleaning plate 404 can press against the limiting plate 408 from the other side. Because the attraction between the gravity iron column 409 and the magnetic adsorption block 410 is greater than the torque of the torsion spring 407, when the cleaning plate 404 presses against the limiting plate 408, the limiting plate 408 rotates around the torsion spring 407, thus removing the restriction on the cleaning plate 404 and allowing it to reset with the sliding block 403. In this way, the two sides of the cleaning plate 404 can sequentially perform snow removal operations on the top side of the protective plate 300. This improves the snow removal effect of the device, thereby improving the overall protective effect of the device.

[0033] The top of the protective plate 300 is equipped with a spraying component 500 for spraying out a salt solution, and the top of the protective plate 300 is equipped with a limiting component 600 for limiting the spraying frequency of the salt solution.

[0034] In use, the reciprocating screw 402 driven by the servo motor is activated, causing it to rotate. Because the sliding block 403, threaded onto the reciprocating screw 402, is restricted by the mounting base 401, the sliding block 403 reciprocates horizontally. The sliding block 403 then drives the cleaning plate 404, which is rotatably connected to it, to reciprocate horizontally. When the cleaning plate 404 reaches the limiting rod 406, it is compressed by the limiting plate 408. Because the limiting plate 408 is restricted by the limiting rod 406, it cannot rotate around the torsion spring 407. Therefore, the cleaning plate 404 rotates under the action of the limiting plate 408, and simultaneously, due to its own inertia, it rotates more than 90 degrees but less than 270 degrees. The gravity iron inside the cleaning plate 404... The column 409 then moves to the other side under the attraction of the magnetic adsorption block 410, thus maintaining the cleaning plate 404 in a state of 180-degree rotation. At this time, the other side of the cleaning plate 404 rotates to a position close to the top of the protective plate 300. When the reciprocating screw 402 continues to rotate, driving the sliding block 403 to reset, the cleaning plate 404 can squeeze the limiting plate 408 from the other side. Because the attraction between the gravity iron column 409 and the magnetic adsorption block 410 is greater than the torsion of the torsion spring 407 itself, when the cleaning plate 404 squeezes the limiting plate 408, the limiting plate 408 rotates around the torsion spring 407 as the axis, thereby removing the restriction on the cleaning plate 404, allowing the cleaning plate 404 to reset with the sliding block 403. In this way, the two sides of the cleaning plate 404 can sequentially perform snow removal operations on the top side of the protective plate 300.

[0035] Example 2, please refer to Figures 1-6 Based on Embodiment 1, the ejection assembly 500 includes a second fixed rod 501, a first bevel gear 502 connected to the outer side of a reciprocating screw 402, and a through-type rotating shaft 503 rotatably connected to the side of the second fixed rod 501. A second bevel gear 504 is fixedly connected to the bottom of the rotating shaft 503, and the second bevel gear 504 is located at the top of the first bevel gear 502 and is meshed with the first bevel gear 502. When the reciprocating screw 402 rotates, it drives the first bevel gear 502, which is connected to the reciprocating screw 402, to rotate. This causes the first bevel gear 502 to drive the second bevel gear 504, which meshes with the first bevel gear 502, to rotate. The second bevel gear 504 then drives the rotating shaft 503, which is fixedly connected to the second bevel gear 504, to rotate.

[0036] A sprocket 505 is fixedly connected to the outer side of the rotating shaft 503. A chain 506 is mounted on the outer side of the sprocket 505. A liquid pump 507 is mounted on the side of the shelf 100. A pipe 508 is fixedly connected to the side of the fixing rod 405. A hose 509 is mounted between the pipe 508 and the liquid pump 507. A pipe connector 510 is rotatably connected to the bottom of the pipe 508. A sprocket 511 is fixedly connected to the outer side of the pipe connector 510. The end of the chain 506 away from the sprocket 505 is mounted on the outer side of the sprocket 511. A nozzle 512 is fixedly connected to the bottom of the pipe connector 510. When the rotating shaft 503 rotates, it drives the sprocket 505, which is fixedly connected to the shaft 503, to rotate. At this time, the liquid pump 507 is activated, and a brine solution is introduced into the pipe 508 through the hose 509. This, combined with the chain 506 mounted on the outside of the sprocket 505, causes the sprocket 511, which is driven by the chain 506 to rotate. The sprocket 511 then drives the pipe connector 510, which is fixedly connected to it, to rotate. The pipe connector 510 then drives the nozzle 512, fixed at its bottom, to rotate, spraying the brine solution from the pipe 508 into the pipe connector 510 through the nozzle 512 onto the top of the protective plate 300. This increases the coverage of the brine solution on the top of the protective plate 300, further improving the snow removal effect of the device.

[0037] In use, based on Embodiment 1, when the reciprocating screw 402 rotates, it drives the bevel gear 502, which is connected to the reciprocating screw 402, to rotate. This causes the bevel gear 502 to drive the bevel gear 504, which meshes with the bevel gear 502, to rotate. The bevel gear 504 then drives the rotating shaft 503, which is fixedly connected to the bevel gear 504, to rotate. This causes the rotating shaft 503 to drive the sprocket 505, which is fixedly connected to the rotating shaft 503, to rotate. At this time, the liquid pump 507 is activated, and liquid is pumped through the hose 509 to... A brine solution is introduced into pipe 508, and then a chain 506 mounted on the outside of sprocket 1 505 causes sprocket 2 511, which is connected to sprocket 1 505 via chain 506, to rotate. Sprocket 2 511 then drives pipe joint 510, which is fixedly connected to sprocket 2 511, to rotate. Pipe joint 510 then drives nozzle 512, which is fixed at its bottom, to rotate. The brine solution injected from pipe 508 into pipe joint 510 is sprayed through nozzle 512 to the top of protective plate 300.

[0038] Example 3, please refer to Figures 1-8Based on Embodiments 1 and 2, the limiting component 600 includes a hydraulic chamber 601. One end of the hydraulic chamber 601 is slidably connected to a force-bearing rod 602, and the other end of the hydraulic chamber 601 is slidably connected to an arc-shaped rod 603. A spring 604 is mounted on the side of the force-bearing rod 602. When the sliding block 403 reciprocates in the horizontal direction and moves towards the force-bearing rod 602, it can compress the force-bearing rod 602 and drive it to move laterally. This, in conjunction with the hydraulic chamber 601 slidably connected to the force-bearing rod 602, increases the pressure inside the hydraulic chamber 601, thereby driving the arc-shaped rod 603 slidably connected to the hydraulic chamber 601 to move.

[0039] A through-hole rotating block 605 is rotatably connected inside the pipe 508. A force-bearing plate 606 is fixedly connected to the outside of the rotating block 605. The force-bearing plate 606 is located on the side of the arc-shaped rod 603 and is fixed to the arc-shaped rod 603. A block 607 is fixedly connected to the bottom of the rotating block 605. When the arc-shaped rod 603 moves, it causes the force-bearing plate 606, which is fixedly connected to the arc-shaped rod 603, to rotate. The force-bearing plate 606 causes the rotating block 605, which is fixedly connected to the force-bearing plate 605, to rotate. This causes the block 607, which is fixedly connected to the rotating block 605, to rotate, opening the pipe 508 that was originally closed by the block 607, thereby spraying out the brine solution.

[0040] As the sliding block 403 continues to move away from the force-bearing rod 602, the force-bearing rod 602 loses the restraint of the sliding block 403 and resets under the action of the spring 604. Similarly, the block 607 resets, restoring the pipe 508 to a closed state. In this way, salt water solution can be intermittently sprayed onto the top of the protective plate 300. This improves the snow removal effect while reducing the waste of salt water solution, making the device easier to use.

[0041] In use, based on Embodiments 1 and 2, when the sliding block 403 reciprocates in the horizontal direction and moves towards the force-bearing rod 602, it can compress the force-bearing rod 602 and drive it to move laterally. This, combined with the hydraulic chamber 601 slidably connected to the force-bearing rod 602, increases the pressure within the hydraulic chamber 601, causing the arc-shaped rod 603 slidably connected to the hydraulic chamber 601 to move. This causes the arc-shaped rod 603 to drive the force-bearing plate 606, which is fixedly connected to the arc-shaped rod 603, to rotate. The force-bearing plate 606 then rotates, causing the force-bearing plate 606, which is fixedly connected to the force-bearing plate 606, to rotate. The rotating block 605, which is fixedly connected, rotates, causing the blocking block 607, which is fixedly connected to the rotating block 605, to rotate, thus opening the pipe 508 that was originally closed by the blocking block 607, thereby spraying out the brine solution. When the sliding block 403 continues to move away from the force rod 602, the force rod 602 loses the restraint of the sliding block 403 and resets under the action of the spring 604. Similarly, the blocking block 607 resets, restoring the pipe 508 to the closed state. In this way, brine solution can be intermittently sprayed onto the top of the protective plate 300.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
