[0005] The utility model discloses a photovoltaic bracket with adjustable inclination angle, which aims to solve the technical problem that the inclination angle of a photovoltaic panel is adjusted by the cooperation of a ratchet and a pawl. If the inclination angle of the photovoltaic panel is adjusted to a large extent, the torque deflected to one side under the action of gravity is large, and the inclination angle of the photovoltaic panel is easily loosened and the fixation is not stable enough by only relying on the pawl to resist the ratchet wheel.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A photovoltaic bracket with adjustable inclination angle comprises a base and a riser fixedly arranged at the upper end of the base, a photovoltaic panel is arranged on one side of the riser, and also comprises: an angle adjustment mechanism: the angle adjustment mechanism comprises a threaded rod rotatably connected to the riser, a push block is threadedly connected to the threaded rod, a guide member for limiting is fixedly arranged on one side of the push block, a through plate is fixedly arranged on the other side of the push block, a through groove is opened on the outer peripheral surface of the riser, a circular frame is fixedly arranged on the through plate passing through the through groove, an end plate is fixedly arranged on the upper end of the riser, a servo motor is fixedly arranged on the upper end of the end plate, the top end of the threaded rod passes through the end plate and is fixedly arranged on the output end of the servo motor, and a rotating member for connecting the photovoltaic panel is arranged on the outer side of the end plate; a cleaning mechanism: the cleaning mechanism is fixedly arranged on one side of the photovoltaic panel, and the cleaning mechanism is used to clean the photovoltaic panel.

[0008] In this solution, the servo motor and the matching time relay can drive the threaded rod to rotate at the set time, thereby controlling the circular frame to move downward at different distances and push the rotating part to control the inclination angle of the photovoltaic panel in different time periods, thereby increasing the area of ​​contact between the photovoltaic panel and light, and through the cleaning mechanism, impurities stuck on the photovoltaic panel can be scraped off.

[0009] In a preferred solution, the guide member includes a slider fixedly arranged on one side of the push block, a slide rail is fixedly arranged on the inner circumferential surface of the vertical pipe, the slider is slidably connected in the slide rail, the rotating member includes a support frame rotatably connected to the outer side of the end plate, the support frame is fixedly arranged on one side of the photovoltaic panel, a first connecting frame is fixedly arranged on one side of the circular frame, a support plate is rotatably connected in the first connecting frame, one end of the support plate is rotatably connected to a second connecting frame, and the second connecting frame is fixedly arranged on one side of the photovoltaic panel.

[0010] By setting two symmetrical sets of sliders and rails, the push block can be limited so that it will not rotate along with the rotation of the threaded rod. When the circular frame moves, the support plate will be pushed to rotate. When the inclination angle of the support plate changes, the photovoltaic panel will be pushed to deflect around the rotation axis of the support frame, thereby adjusting the inclination angle of the photovoltaic panel.

[0011] In a preferred embodiment, the cleaning mechanism includes a guide rail fixedly arranged on the side of the photovoltaic panel, a guide block is slidably connected in the guide rail, a U-shaped frame is fixedly arranged on one side of the guide block, a scraper is fixedly arranged on the inner wall of the U-shaped frame, an L-shaped plate is fixedly arranged at one end of the U-shaped frame, a piston rod is rotatably connected to one side of the L-shaped plate, one end of the piston rod is rotatably connected to the other side of the circular frame, a spray part for sprinkling water is embedded in the piston rod, the spray part includes a one-way valve embedded in one side of the piston rod, a guide pipe is embedded in the other side of the piston rod away from the one-way valve, a water storage barrel is fixedly arranged on the upper end of the base, a water outlet pipe is embedded in one side of the water storage barrel, a diversion pipe is fixedly arranged on the upper end of the U-shaped frame, and a nozzle is installed on the diversion pipe.

[0012] By setting a piston rod, the circular frame can move downward while driving the scraper to move along the photovoltaic panel to remove impurities on the photovoltaic panel. When the circular frame moves upward and resets, the piston rod can transport the water in the water storage barrel to the diversion pipe and spray it out through the nozzle, further improving the cleaning effect.

[0013] The utility model provides a photovoltaic bracket with adjustable inclination angle through improvement, which has the following improvements and advantages compared with the prior art:

[0014] First: In the utility model, when the servo motor drives the threaded rod to rotate forward or reverse, it will drive the push block to move upward or downward, and its circular frame will move along with it. When the circular frame moves upward or downward, it will push the support plate. After the support plate is pushed, its inclination angle will change, and then push the photovoltaic panel to change the inclination angle of the photovoltaic panel. After the servo motor stops, the circular frame is difficult to move, so that the photovoltaic panel can stay stably in the adjusted position and be fixed more stably.

[0015] Second: In the utility model, when the circular frame moves, its piston rod shortens or lengthens as it moves upward or downward, thereby driving the scraper to move along the photovoltaic panel to scrape off impurities thereon, and when the piston rod shortens, the water stored therein is pressed into the diversion pipe and then sprayed out from the nozzle, thereby cleaning the photovoltaic panel while scraping, further improving the cleaning effect.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] The utility model discloses a photovoltaic bracket with adjustable inclination angle, which is mainly used to adjust the inclination angle of the photovoltaic panel through the cooperation of the ratchet and pawl. If the inclination angle of the photovoltaic panel is adjusted to a large extent, the torque deflected to one side under the action of gravity is large, and the inclination angle of the photovoltaic panel is fixed only by the pawl against the ratchet wheel, which is prone to looseness and the fixation is not stable enough.

[0024] Reference Figure 1 , Figure 2 and Figure 4, a photovoltaic bracket with adjustable inclination, comprising a base 1 and a riser 2 fixedly arranged at the upper end of the base 1, a photovoltaic panel 13 is arranged on one side of the riser 2, and also comprising: an angle adjustment mechanism: the angle adjustment mechanism comprises a threaded rod 3 rotatably connected to the riser 2, a push block 4 is threadedly connected to the threaded rod 3, a guide member for limiting is fixedly arranged on one side of the push block 4, a through plate 7 is fixedly arranged on the other side of the push block 4, a through groove 8 is opened on the outer circumferential surface of the riser 2, a circular frame 9 is fixedly arranged on the through plate 7 passing through the through groove 8, an end plate 10 is fixedly arranged on the upper end of the riser 2, a servo motor 11 is fixedly arranged on the upper end of the end plate 10, the top end of the threaded rod 3 passes through the end plate 10 and is fixedly arranged at the output end of the servo motor 11, and a rotating member for connecting the photovoltaic panel 13 is arranged on the outer side of the end plate 10; a cleaning mechanism: the cleaning mechanism is fixedly arranged on one side of the photovoltaic panel 13, and the cleaning mechanism is used to clean the photovoltaic panel 13.

[0025] In this solution, the servo motor 11 and the matching time relay can drive the threaded rod 3 to rotate at the set time. When the threaded rod 3 initially rotates, it will push the circular frame 9 to move downward, and push the photovoltaic panel 13 to one side through the rotating part, so as to adjust the inclination angle of the photovoltaic panel 13 according to the angle of sunlight in different time periods. When the servo motor 11 is started for the last time, the servo motor 11 drives the threaded rod 3 to rotate in the opposite direction, so that the photovoltaic panel 13 is completely reset at one time to prepare for the next adjustment. Through the cleaning mechanism, the photovoltaic panel 13 can be cleaned while adjusting the angle.

[0026] Among them, the guide member includes a slider 5 fixedly arranged on one side of the push block 4, a slide rail 6 is fixedly arranged on the inner circumference of the vertical pipe 2, and the slider 5 is slidably connected in the slide rail 6. By arranging a group of sliders 5 and slide rails 6 on both sides of the push block 4, the push block 4 can be limited so that the push block 4 will not rotate with the rotation of the threaded rod 3, and then the circular frame 9 can be stably driven to move upward or downward.

[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, the rotating member includes a support frame 12 rotatably connected to the outside of the end plate 10, the support frame 12 is fixedly arranged on one side of the photovoltaic panel 13, a first connection frame 14 is fixedly arranged on one side of the circular frame 9, a support plate 15 is rotatably connected in the first connection frame 14, one end of the support plate 15 is rotatably connected to a second connection frame 16, and the second connection frame 16 is fixedly arranged on one side of the photovoltaic panel 13.

[0028] When the circular frame 9 moves upward or downward, the first connecting frame 14 will be driven to move at the same time. Since the two ends of the support plate 15 are rotatably connected to the first connecting frame 14 and the second connecting frame 16, when the first connecting frame 14 moves, the inclination angle of the support plate 15 will also change accordingly, thereby pushing the photovoltaic panel 13 to deflect around the rotation point of the support frame 12. When the servo motor 11 stops, the circular frame 9 cannot move again, so that the photovoltaic panel 13 can stay in the adjusted position more stably and be fixed more firmly.

[0029] Reference Figure 1 and Figure 3 In a preferred embodiment, the cleaning mechanism includes a guide rail 17 fixedly arranged on the side of the photovoltaic panel 13, a guide block 18 is slidably connected in the guide rail 17, a U-shaped frame 19 is fixedly arranged on one side of the guide block 18, a scraper 20 is fixedly arranged on the inner wall of the U-shaped frame 19, an L-shaped plate 21 is fixedly arranged at one end of the U-shaped frame 19, a piston rod 22 is rotatably connected to one side of the L-shaped plate 21, one end of the piston rod 22 is rotatably connected to the other side of the circular frame 9, and a spraying member for sprinkling water is embedded in the piston rod 22.

[0030] Specifically, when the circular frame 9 moves downward, its piston rod 22 will push the L-shaped plate 21, and then drive the scraper 20 in the U-shaped frame 19 to move downward along the photovoltaic panel 13. At the same time, the piston rod 22 extends and the inclination angle changes, so that the scraper 20 can move smoothly downward along the photovoltaic panel 13. Similarly, when the circular frame 9 drives the U-shaped frame 19 to move upward, the piston rod 22 will shorten.

[0031] Furthermore, the length of the scraper 20 is equal to the length of the photovoltaic panel 13, and the spacing between the photovoltaic panel 13 and the inner side of the U-shaped frame 19 is equal to the thickness of the scraper 20, so that the scraping surface of the scraper 20 can fit with the photovoltaic panel 13. When moving, it can better scrape off impurities stuck on the photovoltaic panel 13. At the same time, due to the equal length, there will be no cleaning dead corners.

[0032] Reference Figure 1 and Figure 2 In a preferred embodiment, the spray part includes a one-way valve 23 embedded in one side of the piston rod 22, a guide pipe 24 is embedded in the other side of the piston rod 22 away from the one-way valve 23, a water storage barrel 25 is fixedly provided on the upper end of the base 1, a water outlet pipe 26 is embedded in one side of the water storage barrel 25, a diversion pipe 27 is fixedly provided on the upper end of the U-shaped frame 19, and a nozzle 28 is installed on the diversion pipe 27.

[0033] It is worth mentioning that the one-way valve 23 is connected to one end of the water outlet pipe 26 through a plastic hose, and the guide pipe 24 is connected to the diversion pipe 27 through a plastic hose. When the piston rod 22 is extended, the water in the water storage barrel 25 can be drawn into the piston rod 22 through the one-way valve 23 and the matching plastic hose. When the piston rod 22 is shortened, the guide pipe 24 transports the water flow to the diversion pipe 27 through the plastic hose and sprays it out through the nozzle 28. Therefore, when the scraper 20 moves upward, the nozzle 28 sprays water to further improve the cleaning effect.

[0034] Working principle: When in use, the servo motor 11 will start within the set time under the action of the matching time relay, and then drive the threaded rod 3 to rotate. In the initial stage, while the threaded rod 3 rotates, its circular frame 9 moves downward. While the circular frame 9 moves downward, it will push the support plate 15. After the support plate 15 is pushed, its inclination angle changes, and then pushes the photovoltaic panel 13. After the photovoltaic panel 13 is thrust, it deflects to one side by a certain angle under the action of the support frame 12, and then stops. In the second stage, the servo motor 11 rotates again and continues to change the angle of the photovoltaic panel 13 to one side. The same is true in the third stage, so that the angle of the photovoltaic panel 13 can be changed automatically according to the angle of sunlight in the area. In the fourth stage, the threaded rod 3 rotates in the opposite direction, driving the photovoltaic panel 13 to completely reset and prepare for tomorrow's work. Since the servo motor 11 has a self-locking device, after stopping, its threaded rod 3 cannot rotate again, and the circular frame 9 cannot move either, so that the photovoltaic panel 13 can stay in the adjusted position more stably and be fixed more stably.

[0035] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
