Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to an adjustable photovoltaic support for distributed photovoltaic panels. Background Technology

[0002] A photovoltaic (PV) system, or solar photovoltaic power generation system, is a new type of power generation technology that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. During installation, the PV modules need to be reliably fixed using a dedicated PV bracket to ensure stable system operation.

[0003] While existing photovoltaic (PV) mounting systems can adjust the angle of PV panels, in cold winter regions, snow accumulation on the PV panel surface creates uneven weight distribution, resulting in a lateral thrust that shifts the center of the PV panel, altering its original tilt angle. This prevents the panel from operating according to the predetermined angle adjustment plan, leading to reduced solar radiation reception in certain areas. Therefore, we propose an adjustable PV mounting system for distributed PV panels. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an adjustable photovoltaic support for distributed photovoltaic panels.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An adjustable photovoltaic (PV) bracket for distributed photovoltaic (PV) power generation includes a base. Two support rods are symmetrically fixed to the top of the base. A PV panel mounting frame is rotatably mounted on the top of the two support rods to fix the PV panel. A reset mechanism is provided on the outside of the PV panel mounting frame to clear snow from the PV panel surface. This reset mechanism can clear snow from the PV panel surface to prevent snow from blocking sunlight and significantly reducing the amount of light energy received by the PV panel, thus reducing its power generation. Below the PV panel mounting frame is a collection mechanism for collecting or heating snow. The collection mechanism can collect snow that has fallen onto the PV panel. The increased weight of the collection mechanism causes it to rotate the PV panel mounting frame, turning it from an inclined position to a vertical position. The collection mechanism can also heat the collected snow to make it hot water. When the PV panel mounting frame changes from an inclined position to a vertical position, the reset mechanism clears the snow from the PV panel.

[0007] As a preferred embodiment of the present invention, the reset mechanism includes a limiting frame disposed outside the photovoltaic panel fixing frame, a fixing rod fixed between the limiting frame and the photovoltaic panel fixing frame, a motor fixed at the bottom of the two fixing rods, a scraper for cleaning snow above the lifting plate, a lifting mechanism between the lifting plate and the motor, and a flipping mechanism between the lifting plate and the scraper. The flipping mechanism drives the scraper to rotate, changing the scraper from a vertical state to a vertical state, and flipping the scraper to the side of the photovoltaic panel with snow. The lifting mechanism drives the lifting plate to rise and fall, and the lifting plate drives the scraper to rise and fall, and the scraper cleans the snow on the surface of the photovoltaic panel.

[0008] As a preferred embodiment of the present invention, the lifting mechanism includes a fixed plate fixed to the bottom of the motor and an inclined rod hinged between the base and the photovoltaic panel mounting frame. The output shaft of the fixed plate is fixed with a threaded rod. A baffle is fixed on the side of the lifting plate away from the photovoltaic panel mounting frame. The baffle has a threaded hole adapted to the threaded rod. A sliding groove is provided at the end of the limiting frame away from the photovoltaic panel mounting frame. A protrusion is provided on the side of the lifting plate facing the limiting frame. The protrusion is inserted into the sliding groove. Through the cooperation of the protrusion and the sliding groove, the limiting frame limits the lifting plate. The output shaft of the fixed plate drives the threaded rod to rotate. The threaded rod cooperates with the threaded hole of the baffle, causing the baffle to drive the lifting plate to move vertically up and down. The lifting plate drives the scraper to move vertically up and down, so that the scraper cleans the snow on the surface of the photovoltaic panel.

[0009] As a preferred embodiment of the present invention, the flipping mechanism includes a U-shaped connecting frame fixed on the photovoltaic panel mounting frame and a rotating rod rotatably mounted on the outside of the lifting plate. A connecting rod is fixed between the rotating rod and the scraper. A gear is fixed to the outer wall of the rotating rod. A rack that meshes with the gear is also fixed inside the U-shaped connecting frame. A limiting ring is fixed to the end of the rotating rod away from the connecting rod. A locking block is fixed to the outer wall of the limiting ring. A locking groove that matches the limiting ring is opened at the top of the lifting plate. A locking groove that matches the locking block is opened above the limiting groove. When the lifting plate moves downward, the lifting plate drives the rotating rod to move downward. The rotating rod drives the gear to move downward. The gear and the rack mesh to drive the gear to rotate counterclockwise by 90 degrees. The gear drives the connecting rod to rotate counterclockwise by 90 degrees through the rotating rod. The connecting rod drives the scraper to rotate counterclockwise by 90 degrees, so that the scraper rotates to the side of the photovoltaic panel with snow accumulation.

[0010] As a preferred embodiment of the present invention, a guide block is hinged to the end of the inclined rod away from the photovoltaic panel mounting frame. A guide groove is provided on the top of the base to facilitate the movement of the guide block. A return spring is also provided between the guide block and the guide groove. A guide rail block is fixed to the outer wall of the guide block. A guide rail groove adapted to the guide rail block is provided on the inner wall of the guide groove. The guide rail block is connected to the guide rail groove. When the photovoltaic panel mounting frame rotates, the photovoltaic panel mounting frame pushes the inclined rod to move. The inclined rod pushes the guide block to move along the inside of the guide groove. The guide block compresses the return spring, making the length of the return spring shorter.

[0011] As a preferred embodiment of the present invention, the storage mechanism includes a positioning shaft rotatably installed inside the photovoltaic panel mounting frame. Limiting plates are provided at both ends of the positioning shaft, and a storage basket is fixed to the bottom of both limiting plates. The middle of the storage basket is recessed inward to form a snow storage trough. A positioning groove is provided in the middle of the limiting plates to facilitate the sliding of the positioning shaft. The positioning shaft is located within the positioning groove. Snow on the surface of the photovoltaic panel moves downward under the influence of gravity, causing the snow to enter the snow storage trough, increasing the weight of the storage basket. This change in weight causes the storage basket to move downward. The storage basket, through the limiting plates, drives the positioning shaft to move downward. The positioning shaft drives the photovoltaic panel mounting frame to rotate around the top of the support rod, changing the photovoltaic panel mounting frame from an inclined state to a vertical state.

[0012] As a preferred embodiment of the present invention, a storage battery is fixed to the bottom of the storage basket, and a touch switch is fixed to the outer wall of the storage basket. A pressure rod is also fixed to the bottom of the photovoltaic panel mounting frame. A heating tube is installed inside the snow storage tank, and a water outlet pipe is also fixed to the bottom of the storage basket. The touch switch and the limiting plate are located on the same side. The touch switch is connected to the storage battery through a wire. The storage battery is connected to the heating tube and the motor through wires respectively. When the photovoltaic panel mounting frame is in a vertical state, the photovoltaic panel mounting frame drives the pressure rod to contact the touch switch. The touch switch sets the storage battery to the open state, and the storage battery provides power to the heating tube and the scraper.

[0013] As a preferred embodiment of the present invention, the top of the base is further provided with a water storage tank for storing snow water. A water pump for drawing snow water from the side of the water storage tank is provided, and a nozzle is provided at the outlet of the water pump. The upper half of the water storage tank is provided with a support frame and a water inlet trough adapted to the water outlet pipe. When the photovoltaic panel mounting bracket is in a vertical position, the water outlet pipe moves into the water inlet trough, allowing the snow water in the collection basket to flow into the water storage tank. After the water pump draws the snow water from the water storage tank, the water is sprayed onto the surface of the photovoltaic panel through the nozzle, further improving the cleaning effect.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] 1. This invention effectively removes snow from the surface of photovoltaic panels by using a combination of a reset mechanism, a storage mechanism, a lifting mechanism, a flipping mechanism, a lifting plate, and a scraper, ensuring that the photovoltaic panels can operate stably according to a predetermined angle adjustment plan, thereby maintaining their solar radiation reception and improving power generation efficiency.

[0016] 2. This invention, through the cooperation of structures such as storage basket, limiting plate, positioning shaft, fixing frame and support rod, makes the photovoltaic panel fixing frame change from an inclined state to a vertical state. This not only allows the snow piled on the inclined photovoltaic panel to fall off automatically due to gravity, but also facilitates the maintenance, cleaning and angle adjustment of the photovoltaic panel.

[0017] 3. The present invention, through the cooperation of structures such as guide block, guide groove, guide rail block and guide rail groove, prevents the guide block from dislodging from the guide groove during movement, ensures that the guide block always runs stably within the guide groove, and further enhances the movement stability of the guide block;

[0018] 4. The present invention limits the lifting plate by using a combination of structures such as a limiting frame, a lifting plate, a protrusion and a sliding groove, which prevents the lifting plate from deflecting, improves the accuracy and stability of the lifting plate during the lifting process, and greatly enhances the durability and safety of the entire device, avoiding mechanical failures or safety hazards that may be caused by the deflection of the lifting plate.

[0019] 5. Through the cooperation of the storage basket, battery, positioning shaft and limiting plate, the present invention ensures that the center of gravity of the battery and the storage basket as a whole is always stably kept directly below the storage basket, thereby ensuring that the storage basket can automatically restore and maintain a vertical state under various working conditions, which significantly improves the stability and practicality of the storage device.

[0020] 6. This invention uses a combination of a water pump, a water tank, and a nozzle to spray water onto the surface of the photovoltaic panel. The strong and uniform water pressure washes away dust, dirt, and organic pollutants, increasing the service life of the photovoltaic panel. Attached Figure Description

[0038] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0039] Example: The present invention provides, as follows Figure 1 and Figure 2 The adjustable photovoltaic support for distributed photovoltaic power generation panels shown includes a base 1, two support rods 2 are symmetrically fixed on the top of the base 1, and a photovoltaic panel fixing frame 3 for fixing the photovoltaic panels is rotatably installed on the top of the two support rods 2.

[0040] As can be seen from the above, when using the photovoltaic panel, after the base 1 is installed in the designated position, the photovoltaic panel fixing frame 3 is supported by the support rod 2, and the tilt angle of the photovoltaic panel fixing frame 3 is adjusted before the photovoltaic panel is installed on the photovoltaic panel fixing frame 3.

[0041] refer to Figure 3 and Figure 4 As shown, the photovoltaic panel mounting bracket 3 is externally equipped with a reset mechanism 4 for cleaning snow from the surface of the photovoltaic panel. (Refer to...) Figure 4 , Figure 5 and Figure 6 As shown, the reset mechanism 4 includes a limiting frame 401 disposed outside the photovoltaic panel fixing frame 3. A fixing rod 402 is fixed between the limiting frame 401 and the photovoltaic panel fixing frame 3. A motor 414 is fixed to the bottom of the two fixing rods 402. A scraper 404 for clearing snow is also disposed above the lifting plate 403. A lifting mechanism is also disposed between the lifting plate 403 and the motor 414. (See reference) Figure 6 and Figure 7As shown, the lifting mechanism includes a fixed plate 413 fixed to the bottom of the motor 414 and a diagonal rod 415 hinged between the base 1 and the photovoltaic panel mounting frame 3. The output shaft of the fixed plate 413 is fixed with a threaded rod 406. A baffle is fixed on the side of the lifting plate 403 away from the photovoltaic panel mounting frame 3. The baffle has a threaded hole that matches the threaded rod 406. The reset mechanism 4 can clean the snow on the surface of the photovoltaic panel to prevent snow from covering the surface of the photovoltaic panel, which would block the sunlight and greatly reduce the light energy received by the photovoltaic panel, thus leading to a decrease in its power generation. The limiting frame 401 has a groove at the end away from the photovoltaic panel fixing frame 3. The lifting plate 403 has a protrusion on the side facing the limiting frame 401. The protrusion is inserted into the groove. Through the cooperation of the protrusion and the groove, the limiting frame 401 limits the lifting plate 403. The output shaft of the fixing plate 413 drives the threaded rod 406 to rotate. The threaded rod 406 cooperates with the threaded hole of the baffle, so that the baffle drives the lifting plate 403 to move vertically up and down. The lifting plate 403 drives the scraper 404 to move vertically up and down, so that the scraper 404 cleans the snow on the surface of the photovoltaic panel.

[0042] refer to Figure 7 , Figure 8 and Figure 9 As shown, a flipping mechanism is provided between the lifting plate 403 and the scraper 404. The flipping mechanism includes a U-shaped connecting frame 410 fixed on the photovoltaic panel mounting frame 3 and a rotating rod 408 rotatably installed outside the lifting plate 403. A connecting rod 405 is fixed between the rotating rod 408 and the scraper 404. A gear 409 is fixed to the outer wall of the rotating rod 408. A rack 412 that meshes with the gear 409 is also fixed inside the U-shaped connecting frame 410. A limit ring 411 is also fixed to the end of the rotating rod 408 away from the connecting rod 405. The flipping mechanism drives the scraper 404 to rotate, changing the scraper 404 from a vertical state to a vertical state, and flipping the scraper 404 to the side of the photovoltaic panel with snow accumulation. The lifting mechanism drives the lifting plate 403 to rise and fall, and the lifting plate 403 drives the scraper 404 to move forward. The lifting plate 403 moves downwards, and the scraper 404 cleans the snow on the surface of the photovoltaic panel. A locking block is fixed to the outer wall of the limiting ring 411. The top of the lifting plate 403 has a locking groove that matches the limiting ring 411, and a locking groove that matches the locking block is opened above the limiting groove. When the lifting plate 403 moves downwards, the lifting plate 403 drives the rotating rod 408 to move downwards. The rotating rod 408 drives the gear 409 to move downwards. The gear 409 cooperates with the rack 412 to drive the gear 409 to rotate 90 degrees counterclockwise. The gear 409 drives the rotating rod 408 to rotate 90 degrees counterclockwise. The gear 409 drives the connecting rod 405 to rotate 90 degrees counterclockwise. The connecting rod 405 drives the scraper 404 to rotate 90 degrees counterclockwise, so that the scraper 404 rotates to the side of the photovoltaic panel with snow.

[0043] refer to Figure 10 and Figure 11 As shown, a guide block 416 is hinged to the end of the inclined rod 415 away from the photovoltaic panel mounting frame 3. A guide groove is provided on the top of the base 1 to facilitate the movement of the guide block 416. A return spring 407 is also provided between the guide block 416 and the guide groove. A guide rail block is fixed to the outer wall of the guide block 416. A guide rail groove is provided on the inner wall of the guide groove to match the guide rail block. The guide rail block and the guide rail groove are connected. When the photovoltaic panel mounting frame 3 rotates, the photovoltaic panel mounting frame 3 pushes the inclined rod 415 to move. The inclined rod 415 pushes the guide block 416 to move along the inside of the guide groove. The guide block 416 compresses the return spring 407, making the length of the return spring 407 shorter.

[0044] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when there is snow on the surface of the photovoltaic panel and the angle needs to be adjusted, the output shaft of the fixed plate 413 drives the threaded rod 406 to rotate. The threaded rod 406 engages with the threaded hole of the baffle, causing the baffle to drive the lifting plate 403 to move vertically up and down. When the lifting plate 403 moves downward, it drives the rotating rod 408 to move downward. The rotating rod 408 drives the gear 409 to move downward. The gear 409 engages with the rack 412, causing the gear 409 to rotate 90 degrees counterclockwise. The gear 409 rotates 9 degrees counterclockwise through the rotating rod 408. At 0 degrees, gear 409 drives connecting rod 405 to rotate 90 degrees counterclockwise via rotating rod 408. Connecting rod 405 drives scraper 404 to rotate 90 degrees counterclockwise, so that scraper 404 rotates to the side of photovoltaic panel with snow. Lifting plate 403 drives scraper 404 to move vertically up and down, so that scraper 404 cleans the snow on the surface of photovoltaic panel, so that the center of gravity of photovoltaic panel is restored. Reset spring 407 releases elastic force to push guide block 416 to move, so that guide block 416 pushes inclined rod 415 to move, and inclined rod 415 moves photovoltaic panel fixing frame 3 to the initial position.

[0045] refer to Figure 3 and Figure 4 As shown, a snow collection mechanism 5 for collecting or heating snow is installed below the photovoltaic panel mounting frame 3, for reference. Figure 12 and Figure 13 As shown, the storage mechanism 5 includes a positioning shaft 503 rotatably installed inside the photovoltaic panel mounting frame 3. Both ends of the positioning shaft 503 are provided with limit plates 504. The bottom of the two limit plates 504 are fixed together with a storage basket 501. The middle of the storage basket 501 is recessed inward to form a snow storage trough. The middle of the limit plate 504 is provided with a positioning groove to facilitate the sliding of the positioning shaft 503. The positioning shaft 503 is located in the positioning groove. The storage mechanism 5 can collect the snow that slides off the photovoltaic panel. The snow accumulation increases the weight of the storage mechanism 5, causing the storage mechanism 5 to drive the photovoltaic panel mounting frame 3 to rotate.

[0046] refer to Figure 14 and Figure 15 As shown, a storage battery 502 is fixed to the bottom of the storage basket 501, and a touch switch 506 is fixed to the outer wall of the storage basket 501. A pressure rod 508 is also fixed to the bottom of the photovoltaic panel mounting bracket 3. A heating tube 507 is installed inside the snow storage tank, and a water outlet pipe 505 is also fixed to the bottom of the storage basket 501. The touch switch 506 and the limit plate 504 are located on the same side. The touch switch 506 is connected to the storage battery 502 through a wire. The storage battery 502 is connected to the heating tube 507 and the motor 414 through wires respectively. When the photovoltaic panel mounting bracket 3 is in a vertical state, the photovoltaic panel mounting bracket 3 drives the pressure rod 508 to contact the touch switch 506. The touch switch 506 sets the storage battery 502 to the open state, and the storage battery 502 provides power to the heating tube 507 and the scraper 404.

[0047] refer to Figure 16 As shown, the top of the base 1 is also equipped with a water storage tank 6 for storing snow water. The side of the water storage tank 6 is equipped with a water pump 7 for drawing the snow water inside. The water outlet of the water pump 7 is equipped with a nozzle 8. The upper half of the water storage tank 6 is equipped with a support frame and a water inlet trough that are compatible with the water outlet pipe 505. When the photovoltaic panel fixing frame 3 is in a vertical state, the water outlet pipe 505 moves into the water inlet trough and draws the snow water inside the collection basket 501 into the water storage tank 6. After the water pump 7 draws the snow water inside the water storage tank 6, the water is sprayed onto the surface of the photovoltaic panel through the nozzle 8 to further improve the cleaning effect.

[0048] refer to Figure 12 , Figure 13 and Figure 14 As shown, the snow on the surface of the photovoltaic panel moves downward under the influence of gravity, causing the snow to enter the interior of the snow storage trough, increasing the weight of the storage basket 501. The change in weight of the storage basket 501 causes it to move downward. The storage basket 501 drives the positioning shaft 503 to move downward through the limiting plate 504. The positioning shaft 503 drives the photovoltaic panel fixing frame 3 to rotate around the top of the support rod 2, changing the photovoltaic panel fixing frame 3 from an inclined state to a vertical state.

[0049] Working principle:

[0050] Snow on the surface of the photovoltaic panel moves downwards due to gravity, entering the snow storage trough and increasing the weight of the collection basket 501. This change in weight causes the collection basket 501 to move downwards. The collection basket 501, via the limiting plate 504, drives the positioning shaft 503 downwards. The positioning shaft 503 causes the photovoltaic panel fixing frame 3 to rotate around the top of the support rod 2, changing it from an inclined state to a vertical state. The photovoltaic panel fixing frame 3 causes the pressure rod 508 to contact the touch switch 506, which sets the battery 502 to the open state. The battery 502 provides power to the heating tube 507 and the scraper 404. The output shaft of the fixing plate 413 drives the threaded rod 406 to rotate. The threaded rod 406 engages with the threaded hole of the baffle, causing the baffle to move the lifting plate 403 vertically up and down. When the lifting plate 403 moves downwards... During movement, the lifting plate 403 drives the rotating rod 408 to move downwards, the rotating rod 408 drives the gear 409 to move downwards, the gear 409 engages with the rack 412 to rotate the gear 409 counterclockwise by 90 degrees, the gear 409 rotates counterclockwise by 90 degrees through the rotating rod 408, the gear 409 rotates counterclockwise by 90 degrees through the rotating rod 408, the connecting rod 405 rotates counterclockwise by 90 degrees through the rotating rod 408, the connecting rod 405 rotates counterclockwise by 90 degrees, causing the scraper 404 to rotate to the side of the photovoltaic panel with snow accumulation, the lifting plate 403 drives the scraper 404 to move vertically up and down, so that the scraper 404 cleans the snow accumulation on the surface of the photovoltaic panel, so that the center of gravity of the photovoltaic panel is restored, the reset spring 407 releases its elastic force to push the guide block 416 to move, so that the guide block 416 pushes the inclined rod 415 to move, the inclined rod 415 moves the photovoltaic panel fixing frame 3 to the initial position.
