Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically to an angle adjustment device for solar photovoltaic power generation. Background Technology

[0002] Solar photovoltaic systems, also known as photovoltaics, are facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. Photovoltaic panels often encounter problems such as cleaning difficulties and time-consuming and laborious angle adjustments.

[0003] Patent CN211457061U discloses a photovoltaic panel angle adjustment device, relating to the field of solar power generation technology. The device includes a mounting frame, a base, a solar altitude tracking device, a photovoltaic panel, and a solar azimuth tracking device. The photovoltaic panel angle adjustment device provided by this patent can track the sun's position in two dimensions to achieve maximum solar energy conversion efficiency. This device can achieve consistent movement of multiple photovoltaic panels using two hydraulic cylinders. Although this device solves the problem of adjusting the vertical angle of the photovoltaic panel, the angle adjustment is limited. Therefore, an angle adjustment device for solar photovoltaic power generation is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an angle adjustment device for solar photovoltaic power generation, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an angle adjustment device for solar photovoltaic power generation, including a base plate, an angle adjustment mechanism disposed on the top of the base plate, a motor disposed at the rear of the angle adjustment mechanism, a photovoltaic panel disposed on the top of the angle adjustment mechanism, a cleaning mechanism slidably connected to the surface of the photovoltaic panel, a reciprocating lead screw disposed on the left side of the photovoltaic panel, and a collection chamber disposed at the front of the photovoltaic panel; the angle adjustment mechanism includes a second bevel gear, a spiral rod, a moving block, and a stroke rod, the spiral rod being fixedly connected to the output end of the motor, the second bevel gear being fixedly connected to the outer circumferential surface of the spiral rod, the moving block being movably connected to the outer circumferential surface of the spiral rod, and the stroke rod being rotatably connected to the top of the moving block; the angle adjustment mechanism also includes a first bevel gear, a fixed column, and a rotating plate, The rotating plate is fixedly connected to the bottom of the motor, the fixed column is rotatably connected to the bottom of the rotating plate, the first bevel gear is fixedly connected to the outer circumference of the fixed column, the first bevel gear meshes with the second bevel gear, and the stroke rod is rotatably connected to the photovoltaic panel. The device is placed under the sun, and then the motor is started, driving the screw rod to rotate, which in turn drives the moving block to move along the threaded groove of the screw rod. As the moving block moves, it drives the stroke rod to adjust the angle, thereby adjusting the angle of the top photovoltaic panel and increasing the contact area between the photovoltaic panel and sunlight. While the motor drives the screw rod to rotate, it also drives the second bevel gear to rotate. The second bevel gear meshes with the first bevel gear, causing the rotating plate to rotate and thus driving the photovoltaic panel to rotate, allowing for further angle adjustments.

[0006] Preferably, the cleaning mechanism includes a rotating rod, bristles, a small motor, and a device block. The small motor is mounted on the top of a reciprocating lead screw. The device block is movably connected to the outer circumferential surface of the reciprocating lead screw. The rotating rod is rotatably connected to the right side of the device block. The bristles are fixedly connected to the outer circumferential surface of the rotating rod. The cleaning mechanism also includes a scraper and a striking rod. The scraper is fixedly connected to the right side of the device block. The striking rod is rotatably connected to the outer circumferential surface of the rotating rod via a torsion spring. The bristles, the scraper, and the striking rod are in contact with the surface of the photovoltaic panel. When the photovoltaic panel needs cleaning, the motor is started, which drives the reciprocating screw at the output end to rotate. This causes the device block to move back and forth on the screw groove. As the device block moves back and forth, it drives the rotating rod to move back and forth. While the rotating rod is moving back and forth, the bristles on its surface clean the surface of the photovoltaic panel. At the same time, the friction between the bristles and the surface of the photovoltaic panel causes the rotating rod to rotate, which in turn causes the striking rod to tap the surface of the photovoltaic panel, allowing the dust to fall more effectively into the collection chamber at the bottom. As the device block moves back and forth, it drives the scraper to scrape away large impurities on the surface of the photovoltaic panel, thus achieving the purpose of cleaning the photovoltaic panel.

[0007] Preferably, the collection chamber includes a rhombus-shaped block, a crossbar, a leveling rod, a return spring, a guide plate, and a chamber wall. The rhombus-shaped block is fixedly connected to the front of the spiral rod, the chamber wall is fixedly connected to the front of the rotating plate, the guide plate is fixedly connected to the front wall of the chamber wall, the crossbar is slidably connected to the inner wall of the guide plate, the leveling rod is fixedly connected to the outer circumferential surface of the crossbar, one end of the return spring is fixedly connected to the outer circumferential surface of the guide plate, and the other end of the return spring is fixedly connected to the inner wall of the chamber wall. The rhombus-shaped block contacts the crossbar, and a plurality of leveling rods are provided, which are evenly arrayed on the outer circumferential surface of the crossbar. The bottom plate includes... The system includes a limiting groove, a fixing rod, and a chassis. The fixing rod is fixedly connected to the bottom of the rotating plate, and the chassis is rotatably connected to the bottom of the fixing column. The limiting groove is located on the top of the chassis, and the fixing rod is slidably connected to the inner wall of the limiting groove. When impurities on the surface of the photovoltaic panel are scraped off into the collection chamber by the cleaning mechanism, the spiral rod rotates while driving the front diamond block to rotate. As the diamond block rotates, it drives the crossbar to move laterally, contracting inward and causing the leveling rod to move laterally before being elastically reset by the return spring. Under the reciprocating motion of the leveling rod, the dust inside the collection chamber is spread evenly, preventing excessive accumulation of dust in one place and causing leakage.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. The angle adjustment device for solar photovoltaic power generation, through the cooperation of the motor, drive screw, bevel gear two, and bevel gear one, causes the motor to drive the screw to rotate while also driving bevel gear two to rotate. While rotating, bevel gear two meshes with bevel gear one, causing the rotating plate to rotate and thus driving the photovoltaic panel to rotate, allowing the photovoltaic panel to be adjusted to more angles.

[0010] 2. The angle adjustment device for solar photovoltaic power generation, in cooperation with the striking rod, the collection chamber, and the device block, causes the striking rod to strike the surface of the photovoltaic panel, allowing dust to fall better into the collection chamber at the bottom. At the same time, the device block moves back and forth, driving the scraper to scrape off large impurities on the surface of the photovoltaic panel, thereby achieving the purpose of cleaning the photovoltaic panel.

[0011] 3. The angle adjustment device for solar photovoltaic power generation, through the cooperation of the drive crossbar, the leveling bar, and the collection chamber, causes the drive crossbar to move laterally and retract inward, driving the leveling bar to move laterally and then being elastically reset by the return spring. Under the reciprocating motion of the leveling bar, the dust inside the collection chamber will be spread evenly, preventing excessive accumulation of dust in a certain place and causing leakage.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-6One embodiment of the present invention is as follows: an angle adjustment device for solar photovoltaic power generation includes a base plate 6, an angle adjustment mechanism 3 is provided on the top of the base plate 6, a motor 2 is provided at the rear of the angle adjustment mechanism 3, a photovoltaic panel 1 is provided on the top of the angle adjustment mechanism 3, a cleaning mechanism 4 is slidably connected to the surface of the photovoltaic panel 1, a reciprocating screw 7 is provided on the left side of the photovoltaic panel 1, and a collection chamber 5 is provided at the front of the photovoltaic panel 1; the angle adjustment mechanism 3 includes a bevel gear 302, a screw rod 304, a moving block 306, and a stroke rod 307, the screw rod 304 is fixedly connected to the output end of the motor 2, and the bevel gear 302... 302 is fixedly connected to the outer circumferential surface of the screw rod 304, the moving block 306 is movably connected to the outer circumferential surface of the screw rod 304, and the stroke rod 307 is rotatably connected to the top of the moving block 306; the angle adjustment mechanism 3 also includes a bevel gear 301, a fixed column 303, and a rotating plate 305. The rotating plate 305 is fixedly connected to the bottom of the motor 2, the fixed column 303 is rotatably connected to the bottom of the rotating plate 305, the bevel gear 301 is fixedly connected to the outer circumferential surface of the fixed column 303, the bevel gear 301 meshes with the bevel gear 302, and the stroke rod 307 is rotatably connected to the photovoltaic panel 1.

[0021] The cleaning mechanism 4 includes a rotating rod 401, bristles 402, a small motor 403, and a device block 405. The small motor 403 is located on the top of the reciprocating lead screw 7. The device block 405 is movably connected to the outer circumferential surface of the reciprocating lead screw 7. The rotating rod 401 is rotatably connected to the right side of the device block 405. The bristles 402 are fixedly connected to the outer circumferential surface of the rotating rod 401. The cleaning mechanism 4 also includes a scraper 404 and a striking rod 406. The scraper 404 is fixedly connected to the right side of the device block 405. The striking rod 406 is rotatably connected to the outer circumferential surface of the rotating rod 401 via a torsion spring. The bristles 402 are in contact with the surface of the photovoltaic panel 1, the scraper 404 is in contact with the surface of the photovoltaic panel 1, and the striking rod 406 is in contact with the surface of the photovoltaic panel 1.

[0022] Working principle: Place the device under the sun, then start the motor 2 to drive the screw rod 304 to rotate, which in turn drives the moving block 306 to move on the threaded groove of the screw rod 304. As the moving block 306 moves, it drives the travel rod 307 to adjust the angle, thereby adjusting the angle of the photovoltaic panel 1 at the top, thus increasing the contact area between the photovoltaic panel 1 and the sunlight. While the motor 2 drives the screw rod 304 to rotate, it also drives the second bevel gear 302 to rotate. As the second bevel gear 302 rotates, it meshes with the first bevel gear 301, causing the rotating plate 305 to rotate, which in turn drives the photovoltaic panel 1 to rotate, allowing the photovoltaic panel 1 to be adjusted to a wider angle.

[0023] When the photovoltaic panel 1 needs cleaning, the small motor 403 is started, which drives the reciprocating screw 7 at the output end to rotate, causing the device block 405 to move back and forth on the screw groove of the reciprocating screw 7. When the device block 405 moves back and forth, it drives the rotating rod 401 to move back and forth. While the rotating rod 401 moves back and forth, the bristles 402 on its surface clean the surface of the photovoltaic panel 1. At the same time, the friction between the bristles 402 and the surface of the photovoltaic panel 1 causes the rotating rod 401 to rotate, which causes the striking rod 406 to strike the surface of the photovoltaic panel 1, allowing the dust to fall better into the collection chamber 5 at the bottom. While the device block 405 moves back and forth, it drives the scraper 404 to scrape off the coarse impurities on the surface of the photovoltaic panel 1, thus achieving the purpose of cleaning the photovoltaic panel 1.

[0025] Working principle: When impurities on the surface of photovoltaic panel 1 are scraped off into collection chamber 5 by cleaning mechanism 4, the spiral rod 304 rotates while driving the front diamond block 501 to rotate. The diamond block 501 rotates while driving the crossbar 502 to move laterally, contracting inward and driving the leveling rod 503 to move laterally. Then, the return spring 504 elastically resets the leveling rod 503.
