Description

Technical Field

[0001] This application relates to the technical field of photovoltaic support equipment, and in particular to an intelligent tracking photovoltaic support. Background Art

[0002] Currently, due to the increasing scarcity of resources, while solar energy is inexhaustible and does not cause pollution, people are using solar energy more and more. Existing solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. They are generally made of aluminum alloy, carbon steel and stainless steel.

[0003] In related technologies, Chinese Patent Publication No. CN214101294U discloses a dust-removing and snow-proof tracking solar photovoltaic bracket, including a bracket mechanism. A photovoltaic panel is fixedly installed at the top of the bracket mechanism. A support mechanism is rotatably connected to the side of the bracket mechanism. Two support mechanisms are symmetrically arranged on the left and right sides of the bracket mechanism. A cleaning mechanism is rotatably connected between the two support mechanisms and is placed tangentially on the top surface of the support mechanism. Two pneumatic mechanisms are rotatably connected to the front of the bracket mechanism and are symmetrically arranged on the front and rear sides of the bracket mechanism. The pneumatic mechanisms are connected to the cleaning mechanism through the support mechanism. The cleaning mechanism is tangential to the photovoltaic panel. As the photovoltaic panel rotates, it drives the cleaning mechanism to move, thereby cleaning dust and snow from the surface of the photovoltaic panel and ensuring that the photovoltaic panel can absorb light energy normally.

[0004] Regarding the aforementioned technologies, the inventors believe that the photovoltaic panel drives the cleaning mechanism to clean during rotation, so the cleaning area of ​​the photovoltaic panel is relatively small, and there are areas that the cleaning mechanism cannot reach. These areas accumulate a lot of dust, which leads to a decrease in the absorption efficiency of solar energy, thereby reducing the utilization rate of the photovoltaic panel. Summary of the Invention

[0005] To improve the utilization rate of photovoltaic panels, this invention provides an intelligent tracking photovoltaic bracket.

[0006] The intelligent tracking photovoltaic bracket provided by this invention adopts the following technical solution:

[0007] A smart tracking photovoltaic bracket includes a bracket mechanism. The bracket mechanism includes a support rod and a support frame connected to the support rod. The support rod is connected to a rotating component for adjusting the angle of the support frame. A photovoltaic panel is connected to the support frame. A cleaning component for cleaning the photovoltaic panel is connected to the support frame. A sliding bracket for supporting the cleaning component is connected to the support frame. The sliding bracket includes a placement plate connected to the support frame. The length of the placement plate is greater than the length of the support frame. The rotating component is connected to a synchronization mechanism that drives the cleaning component to move synchronously with the rotating component.

[0008] By adopting the above technical solution, the orientation of the photovoltaic panel needs to be adjusted according to the angle of sunlight. The rotating component drives the support frame to rotate, and the rotation of the support frame drives the photovoltaic panel to rotate. At the same time, the rotating component drives the synchronous mechanism to move, and the synchronous mechanism drives the cleaning component to move. Since the length of the placement plate is greater than the length of the support frame, the cleaning component can be detached from the photovoltaic panel, so that the cleaning component can clean the photovoltaic panel completely, thereby improving the utilization rate of the photovoltaic panel.

[0009] Preferably, the rotating assembly includes a rotating shaft fixedly connected to the support frame, a driving component for driving the rotating shaft to rotate, the rotating shaft being rotatably connected to the support rod, and the rotating shaft being connected to the synchronization mechanism.

[0010] By adopting the above technical solution, the driving component drives the rotating shaft to rotate, the rotating shaft drives the support frame to rotate, the support frame rotates and drives the photovoltaic panel to rotate, the rotating shaft simultaneously drives the synchronous mechanism to move, the synchronous mechanism drives the cleaning component to move and clean the photovoltaic panel, thereby improving the utilization rate of the photovoltaic panel.

[0011] Preferably, the synchronization mechanism includes a synchronization component connected to the rotating shaft, the synchronization component including a gear fixedly connected to the rotating shaft and a rack meshing with the gear, the length direction of the rack being perpendicular to the length direction of the rotating shaft.

[0012] By adopting the above technical solution, the rotating shaft drives the support frame to rotate, which in turn drives the gear to rotate. The gear drives the rack to move, and the direction of the rack's movement is perpendicular to the length direction of the rotating shaft. This allows the cleaning component to move on the photovoltaic panel, cleaning the photovoltaic panel and improving its utilization rate.

[0013] Preferably, the synchronization mechanism further includes a fixing component connected to the rack, the fixing component including a fixing cylinder fixedly connected to the rack, a fixing rod slidably connected to the fixing cylinder, a return spring placed inside the fixing cylinder and connected to the fixing cylinder, the return spring being connected to the fixing rod, the fixing cylinder being sleeved on the fixing rod, and the fixing rod being connected to the cleaning component.

[0014] By adopting the above technical solution, the rack moves, causing the fixed cylinder to move, which in turn moves the fixed rod, which in turn moves the cleaning component. During the rotation of the support frame, the distance between the support frame and the rack constantly changes, allowing the return spring to contract or extend, thus facilitating the sliding of the fixed rod.

[0015] Preferably, the sliding bracket further includes a support column fixedly connected to the support frame, and the length direction of the placement plate is parallel to the length direction of the rack.

[0016] By adopting the above technical solution, the support column increases the height of the placement plate and support frame, facilitating the placement of gears with larger diameters and preventing the rack from moving too short a distance, which could lead to incomplete cleaning of the photovoltaic panels and reduce their utilization rate. Simultaneously, the support column increases the gap between the placement plate and support frame, preventing the photovoltaic panels from contacting the frame, reducing dust accumulation, and making cleaning easier. The placement plate and rack must be parallel in their length directions to enable the rack to drive the fixed cylinder during movement, which in turn drives the fixed rod, which in turn moves the cleaning assembly.

[0017] Preferably, the cleaning component includes a slider slidably connected to the placement frame, a sliding rod connected to the slider, and a cleaning component connected to the sliding rod, wherein the fixing rod is rotatably connected to the slider.

[0018] By adopting the above technical solution, the slider drives the sliding rod to slide on the placement plate. The sliding rod moves the cleaning component, which then cleans the photovoltaic panel. The placement plate supports the slider and restricts its position, preventing the slider from causing the cleaning component to shake during sliding.

[0019] Preferably, the support frame is connected to a working rod on its side wall in the same direction as the rotation axis, and the top of the working rod is flush with the top of the photovoltaic panel.

[0020] By adopting the above technical solution, when cleaning the photovoltaic panel, the cleaning block collides with the edge of the photovoltaic panel and rotates. The sliding rod cooperates with the rotated cleaning block to achieve contact between the cleaning component and the photovoltaic panel. The slider continues to slide, allowing the cleaning component to clean the photovoltaic panel. The slider slides from both ends of the placement plate, and the sidewalls of the cleaning component that abut against the photovoltaic panel are different, resulting in a more thorough cleaning of the photovoltaic panel. The action rod reduces wear on the end face of the photovoltaic panel caused by the cleaning component.

[0021] Preferably, the support frame is fixedly connected to a support plate, the support plate has a sliding hole, and a bolt threadedly connected to the support rod is placed in the sliding hole, the bolt being slidably connected to the support plate.

[0022] By adopting the above technical solution, the sliding hole and bolt combination restricts the position of the support frame. At the same time, the bolt and the support rod are threaded together, which increases the support force of the support plate on the support frame, prevents the support frame from separating from the support rod, makes the support frame more stable, and increases the service life of the support frame.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. The rotating component belt drives the cleaning component to move through the support mechanism. The cleaning component cleans the photovoltaic panel during the movement. Only one driving component is used to achieve the rotation and cleaning of the photovoltaic panel at the same time.

[0025] 2. Because the length of the placement plate is greater than the length of the placement frame, the cleaning component can clean the entire photovoltaic panel, preventing dust accumulation on the photovoltaic panel and improving the utilization rate of the photovoltaic panel.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] A smart tracking photovoltaic bracket, referring to Figure 1 and Figure 2 It includes a support mechanism 1, a photovoltaic panel 2, a rotating component 4, and a cleaning component 7. The photovoltaic panel 2 is connected to the support mechanism, the rotating component 4 is connected to the support mechanism 1 to adjust the angle of the photovoltaic panel 2, and the cleaning component 7 is connected to the support mechanism 1 and the photovoltaic panel 2 to clean the photovoltaic panel 2.

[0034] Reference Figure 1 and Figure 2 The support mechanism 1 includes a support rod 11 and a support frame 12. The support rod 11 is cuboid in shape, vertically installed and fixed to the ground. The top of the support rod 11 is connected to the support frame 12. The support frame 12 is a horizontally installed cuboid frame. A reinforcing rod 121, also cuboid in shape, is connected to the inner wall of the support frame 12 along its width direction. The length of the reinforcing rod 121 is the same as the length of the support frame 12. The side wall of the support frame 12 away from the support rod 11 is fixedly connected to the bottom of the photovoltaic panel 2. The photovoltaic panel 2 covers the support frame 12. The reinforcing rod 121 increases the supporting force of the support frame 12 on the photovoltaic panel 2.

[0035] Reference Figure 1 A support plate 3 is provided between the support rod 11 and the support frame 12. The support plate 3 is a plate-shaped body with a semi-circular cross-section. The axis of the support plate 3 is perpendicular to the axis of the support rod 11. The two free ends of the support plate 3 are fixedly connected to the side wall of the reinforcing rod 121 away from the photovoltaic panel 2. A semi-circular sliding hole 31 is opened on the side wall of the support plate 3. A bolt is placed in the sliding hole 31. The bolt is placed horizontally and is slidably connected to the support plate 3. The bolt is threadedly connected to the support rod 11 to realize the sliding connection between the support plate 3 and the support rod 11. The support plate 3 increases the support of the support rod 11 for the support frame 12, and the sliding hole 31 restricts the rotation angle of the support frame 12.

[0036] Reference Figure 1 The support rod 11 is connected to the rotating assembly 4. The rotating assembly 4 includes a driving component and a rotating shaft 42. To achieve the same purpose, the driving component can be a motor 41, an engine, etc. In this embodiment, a motor 41 is selected. The motor 41 is fixedly connected to a placement platform. The rotating shaft 42 is horizontally arranged. The driving rod of the motor 41 is fixedly connected to one end of the rotating shaft 42. The circumferential wall of the rotating shaft 42 is fixedly connected to the support frame 12. A placement groove 111 is opened at the top of the support rod 11. The rotating shaft 42 is placed in the placement groove 111 and rotatably connected to the top of the support rod 11.

[0037] Motor 41 drives rotating shaft 42 to rotate, rotating shaft 42 drives support frame 12 to rotate, and support frame 12 drives photovoltaic panel 2 to rotate. Support rod 11 supports rotating shaft 42.

[0038] Reference Figure 2 and Figure 3A synchronization mechanism 5 is connected to the end of the rotating shaft 42 away from the motor 41. The synchronization mechanism 5 includes a synchronization component 51 and a fixed component 52. The synchronization component 51 is connected to the fixed component 52. The synchronization component 51 includes a gear 511 and a rack 512. The gear 511 is fixedly connected to the rotating shaft 42. The rack 512 is horizontally arranged, and its length direction is perpendicular to the length direction of the rotating shaft 42. The rack 512 meshes with the gear 511. The rotating shaft 42 drives the support frame 12 to rotate, and at the same time, it drives the gear 511 to rotate. The gear 511 drives the rack 512 to move.

[0039] Reference Figure 4 A support assembly 9 is connected to the side wall of the support rod 11. The support assembly 9 includes a first connecting plate 91 and a second connecting plate 92. The first connecting plate 91 is rectangular and horizontally arranged. One end of the first connecting plate 91 is fixedly connected to the side wall of the support rod 11, and the other end is fixedly connected to the second connecting plate 92. The second connecting plate 92 is also rectangular and horizontally arranged. The length direction of the second connecting plate 92 is perpendicular to the length direction of the rotation shaft 42. A groove 921 matching the rack 512 is provided on the top of the second connecting plate 92. The length of the groove 921 is the same as the length of the second connecting plate 92. The rack 512 is placed in the groove 921 and is slidably connected to the second connecting plate 92. The groove 921 on the second connecting plate 92 restricts the direction of movement of the rack 512.

[0040] Reference Figure 2 and Figure 3 A fixing component 52 is fixedly connected to the side wall of the rack 512. The fixing component 52 includes a fixing cylinder 521, a fixing rod 522, and a return spring 523. The fixing cylinder 521 is vertically arranged, and the outer wall of the fixing cylinder 521 is fixedly connected to the side wall of the gear 511 away from the support rod 11. The fixing rod 522 is L-shaped, and the vertical section of the fixing rod 522 extends into the fixing cylinder 521 and is fixedly connected to a protrusion 5221. The protrusion 5221 is slidably connected to the inner wall of the fixing cylinder 521. The return spring 523 is vertically arranged, and the top of the return spring 523 is fixedly connected to the bottom of the protrusion 5221. The bottom of the return spring 523 is fixedly connected to the fixing cylinder 521.

[0041] The protrusion 5221 is slidably connected to the fixed cylinder 521, which in turn makes the fixed rod 522 slidably connected to the fixed cylinder 521. During the rotation of the support frame 12, the fixed cylinder 521 moves in the vertical direction, and the return spring 523 facilitates the movement of the support rod 11 in the vertical direction.

[0042] Reference Figure 2The support frame 12 is connected to a sliding bracket 6. The sliding bracket 6 includes a support column 61 and a placement plate 62. Multiple support columns 61 are vertically arranged, and the bottom of the support column 61 is fixedly connected to the support frame 12. Two placement plates 62 are horizontally arranged. The length direction of the two placement plates 62 is parallel to the length direction of the rack 512. The top of the support column 61 is fixedly connected to the bottom of the placement plate 62. The length of the placement plate 62 is greater than the length of the support frame 12.

[0043] The support column 61 increases the height of the placement plate 62 and the support frame 12, which makes it easier to place the gear 511 with a larger diameter and prevents the rack 512 from moving too short a distance.

[0044] Reference Figure 3 The placement plate 62 has a sliding cavity 621 inside, the length of which is greater than the length of the support frame 12. Both placement plates 62 have through holes 622 on their adjacent sidewalls, which communicate with the sliding cavity 621. The length of the through hole 622 is the same as the length of the sliding cavity 621, but the height of the through hole 622 is less than the height of the sliding cavity 621. The placement plate 62 restricts the movement direction of the slider 71.

[0045] Reference Figure 3 The placement plate 62 is connected to a cleaning component 7, which includes a slider 71, a sliding rod 72, and a cleaning block 73. Two sliders 71 and two sliding rods 72 are provided. The two sliders 71 are respectively placed in the sliding cavities 621 of the two placement plates 62. The sliding rod 72 is L-shaped, with its horizontal section placed in a through hole 622 and fixedly connected to the slider 71. The horizontal section of the fixing rod 522 passes through the through hole 622 and is rotatably connected to the slider 71. The fixing rod 522 drives the slider 71 to move, and the slider 71 drives the sliding rod 72 to move synchronously.

[0046] Reference Figure 2 and Figure 3 The cleaning block 73 is rectangular in shape, and all the edges of the cleaning block 73 are rounded. The bottom ends of the vertical sections of the two sliding rods 72 are rotatably connected to the two ends of the cleaning block 73 respectively. A cleaning cloth 731 is fitted on the cleaning block 73. The inner wall of the cleaning cloth 731 is fixedly connected to the outer wall of the cleaning block 73, and the outer wall of the cleaning cloth 731 abuts against the top of the photovoltaic panel 2.

[0047] Because the sliding rod 72 is rotatably connected to the cleaning block 73, when the slider 71 starts to slide from one end of the placement plate 62, the cleaning block 73 collides with the edge of the photovoltaic panel 2 and rotates. The sliding rod 72 cooperates with the rotated cleaning block 73 to ensure that the cleaning cloth 731 is in close contact with the photovoltaic panel 2. The slider 71 continues to slide, allowing the cleaning cloth 731 to clean the photovoltaic panel 2. The slider 71 slides from both ends of the placement plate 62, and the sidewalls of the cleaning cloth 731 that contacts the photovoltaic panel 2 are different, resulting in a more thorough cleaning of the photovoltaic panel 2.

[0048] Reference Figure 2 and Figure 3 An actuating rod 8 is connected to the side wall of the support frame 12, which is in the same length direction as the rotating shaft 42. The actuating rod 8 is cuboid in shape, and its length direction is the same as that of the cleaning block 73. The top of the actuating rod 8 is flush with the top of the photovoltaic panel 2. The actuating rod 8 will not collide with the end face of the photovoltaic panel 2 when the cleaning block 73 starts to move, thereby reducing the mutual wear between the photovoltaic panel 2 and the cleaning cloth 731.

[0049] The operating principle of this application is as follows: Motor 41 drives rotating shaft 42 to rotate, rotating shaft 42 drives support frame 12 to rotate, and simultaneously rotating shaft 42 drives gear 511 to rotate, gear 511 drives fixed cylinder 521 to move, fixed cylinder 521 drives fixed rod 522 to move, fixed rod 522 drives slider 71 to move on placement plate 62, slider 71 drives sliding rod 72 to move, sliding rod 72 drives cleaning block 73 to move, cleaning cloth 731 is fitted on cleaning block 73 and cleans photovoltaic panel 2. Only one drive is used, reducing energy consumption. Since the length of placement plate 62 is greater than the length of support frame 12, cleaning block 73 can be detached from photovoltaic panel 2. Therefore, cleaning block 73 drives cleaning cloth 731 to thoroughly clean photovoltaic panel 2, preventing dust from accumulating on the surface of photovoltaic panel 2, thereby improving the utilization rate of photovoltaic panel 2.

[0050] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
