Description

Technical Field

[0001] This application relates to the field of photovoltaic bracket design, and more particularly to an adjustable solar photovoltaic bracket. Background Technology

[0002] Solar photovoltaic (PV) panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. When in use, solar PV panels are often placed, installed, and fixed by a solar PV support system, and the support structure is an important component of the solar PV support system.

[0003] The existing support structure is not only used for the installation and fixing of photovoltaic panels, but also for flexibly adjusting the installation angle of photovoltaic panels according to sunlight or season. Usually, the adjustment components used to adjust the support structure are often located on the outside of the photovoltaic bracket. Without supervision, outsiders may touch the adjustment components, causing the installation angle of the photovoltaic panels to change, which in turn creates a large deviation angle between the photovoltaic panels and the sunlight, affecting the power generation efficiency of the photovoltaic panels. This needs to be improved. Summary of the Invention

[0004] Based on this, this application provides an adjustable solar photovoltaic bracket that can reduce the chance of unexpected changes in the installation angle of the photovoltaic bracket and ensure the power generation efficiency of the photovoltaic panels.

[0005] The adjustable solar photovoltaic bracket provided in this application adopts the following technical solution:

[0006] An adjustable solar photovoltaic support includes a main beam, at least one support column, and at least one semi-circular plate frame, wherein the support column is fixed to the foundation carrier, the top of the support column is provided with a rotating structure, and the main beam is fixedly installed on the rotating structure.

[0007] The semi-circular frame is fixed to the main beam and is used to install photovoltaic panels. An adjustment mechanism is provided between the semi-circular frame and the support column to adjust the angle of the semi-circular frame, and the support column is equipped with a locking mechanism for positioning the rotation angle of the semi-circular frame.

[0008] The locking mechanism includes a rotating rod, a first plate, a rocker arm assembly, a second plate, and a sliding rod. The rotating rod is rotatably connected to the support column, and the axis of the rotating rod is perpendicular to the extension direction of the main beam. The first plate is fixedly sleeved on the rotating rod, and a housing assembly for covering the rotating rod and the first plate is fixed on the side of the support column.

[0009] The sliding rod is movably inserted through the support column. The sliding rod moves in the same direction as the extension direction of the main beam. The sliding rod is fixed with a limiting component for locking the adjustment mechanism. In use, the adjustment mechanism is locked by the limiting component. The second plate is rotatably sleeved on the sliding rod, and the second plate and the sliding rod are axially linked.

[0010] One end of the rocker arm component is rotatably connected to the first plate, and the rotation axis of the rocker arm component and the first plate is set in the same direction as the central axis of the rotating rod; the other end of the rocker arm component is movably connected to the second plate through a movable structure, and the rocker arm component and the second plate are rotatably connected, and the rotation axis of the second plate and the rocker arm component is perpendicular to the central axis of the rotating rod.

[0011] By adopting the above technical solution, this application adjusts the installation angle of the semi-circular frame through an adjustment mechanism, thereby adjusting the angle of the photovoltaic panel installed on the semi-circular frame. This ensures that sunlight shines directly onto the photovoltaic panel in different seasons, guaranteeing the power generation efficiency of the photovoltaic panel. Furthermore, the locking mechanism can lock the adjustment mechanism, keeping the installation angle of the semi-circular frame fixed.

[0012] Specifically, after the angle of the semi-circular frame is determined, the first plate is rotated by manipulating the rotating rod. The first plate drives the rocker arm to move in a direction perpendicular to the central axis of the rotating rod, which in turn drives the second plate to move in the same direction. At this point, the axial linkage between the second plate and the sliding rod allows the sliding rod to move along its own axis, thereby locking the adjusting mechanism with a limiting component. This maintains the fixed angle of the semi-circular frame and reduces the possibility of deflection if an external person bumps into it. Simultaneously, the housing component mounted on the support column protects the rotating rod, reducing the likelihood of accidental unlocking of the limiting component due to external personnel impacting it. This further reduces the possibility of unintended changes in the photovoltaic panel's installation angle, ensuring the photovoltaic panel maintains good power generation efficiency.

[0013] Optionally, the movable structure includes a strip hole in the second plate, a through hole in the rocker arm component, and a connector that is rotatably inserted between the strip hole and the through hole. The connecting component is movably disposed within the strip hole. One end of the connector has a head, and the other end of the connector is connected to a locking cap. The locking cap and the head together clamp and limit the rocker arm component and the second plate.

[0014] By adopting the above technical solution, by inserting the connector through the strip hole and the through hole, and after the end of the connector abuts against the rocker arm component or the second plate, the locking cap is connected to the end of the connector away from the end. This allows the locking cap and the end to clamp the rocker arm component and the second plate together. At this time, the connector can move within the strip hole, which is beneficial for the smooth rotation and avoidance of the rocker arm component when the locking mechanism is activated, and reduces interference between components or even jamming.

[0015] Optionally, the inner bottom wall of the housing component is provided with a telescopic mechanism, which is located on the outer side of the first plate; wherein,

[0016] The telescopic mechanism includes a fixed column fixed to the housing component, a movable column movably inserted into the fixed column, and a compression spring disposed between the fixed column and the movable column. The compression spring is used to force the movable column to move away from the fixed column.

[0017] When the photovoltaic bracket is reset from the adjustment state to the use state, the first plate can abut against the movable column and force the movable column to move downward; in the use state, the first plate abuts against the side of the movable column.

[0018] By adopting the above technical solution, when the photovoltaic bracket needs to be reset from the adjustment state to the use state, the rotating rod is rotated to drive the first plate to rotate downward. The first plate can abut against the movable column and force the movable column to move downward. At this time, the compression spring is in the contracted state. After the limiting component locks the limiting adjustment mechanism, the photovoltaic panel is in the use state. At this time, the first plate leaves the movable column and moves to the outer side of the movable column. The elastic force of the compression spring acting on the movable column can force the movable column to automatically reset, and the first plate can abut against the side of the movable column, thereby realizing the positioning of the first plate and the rotating rod, reducing the arbitrary rotation of the rotating rod, and maintaining the installation angle of the semi-circular bracket and the photovoltaic panel.

[0019] Optionally, the housing component has an operating hole that communicates with the interior, and the side of the housing component has a movable plate for opening and closing the operating hole. The movable plate is vertically slidably connected to the housing component. A connecting rod is fixed between the movable plate and the movable column. When the operating hole is in the open state, the movable column moves to below the first plate.

[0020] By adopting the above technical solution, and by setting a vertically sliding movable plate, and connecting the movable plate and the movable column through a connecting rod, the movable column normally remains in a position away from the fixed column under the elastic force of the compression spring. At this time, the movable plate can remain closed in the operating hole, reducing the possibility of external personnel rotating the rotating rod and causing the locking mechanism to be released. In addition, when the operator needs to unlock the locking mechanism to adjust the installation angle of the photovoltaic panel, by forcing the movable plate to move downward, the movable column can be automatically driven to retract into the fixed column, so that the operator can operate the rotating rod to rotate.

[0021] Optionally, the locking mechanism also includes an operating lever for controlling the rotation of the rotating lever, the end of the operating lever being provided with a spline block, and the end of the rotating lever being provided with a spline groove that engages with the spline block.

[0022] The movable plate is equipped with a lock hole. The inner diameter of both the operating hole and the lock hole are matched with the outer diameter of the control lever. When the movable column moves to the bottom of the first plate, the lock hole and the operating hole are aligned so that the control lever can be inserted.

[0023] By adopting the above technical solution, when the operator forces the movable plate to move and moves the lock hole to a position directly opposite the operating hole, the operating lever is inserted into the lock hole and the operating hole, which can restrict the reset movement of the movable plate so as to facilitate the smooth rotation of the rotating lever. At this time, through the cooperation of the spline block and the spline groove, the circumferential linkage of the operating lever and the rotating lever can be realized. The operator can easily drive the rotating lever to rotate through the operating lever, thereby allowing the limiting component to smoothly disengage from the adjustment mechanism for unlocking.

[0024] Optionally, a counterweight is connected to the end of the first plate furthest from the rotating rod.

[0025] By adopting the above technical solution, and by setting a counterweight, the weight of the counterweight acts normally on the first plate, which can force the first plate to automatically rotate downward to the limit position, so that the first plate can be stopped against the side of the movable column, reducing the possibility of arbitrary rotation of the rotating rod.

[0026] Optionally, the adjustment mechanism includes an arc-shaped rack and a meshing gear that meshes with it; wherein, the arc-shaped rack is integrally formed on the outer arc surface of the semi-arc plate frame, the support column fixing frame is provided with a mounting bracket, and the meshing gear is rotatably mounted on the mounting bracket; the limiting component is used to engage with the meshing gear for locking.

[0027] By adopting the above technical solution, through the cooperation of the arc rack and the meshing gear, after the limiting component disengages from the meshing gear, the semi-arc plate frame can be directly moved to adjust the angle of the semi-arc plate frame, which has the advantages of quick adjustment and convenient use; after the angle of the semi-arc plate frame is determined, by making the limiting component re-engage with the meshing gear and lock it, the rotation angle of the semi-arc plate frame can be maintained.

[0028] Optionally, the limiting component includes a connecting plate and a locking accessory. The connecting plate is fixedly sleeved on the sliding rod, and the locking accessory is connected to the connecting plate. The side of the meshing gear is provided with an annular tooth groove, and the side of the locking accessory is provided with an annular tooth block. In use, the annular tooth block and the annular tooth groove mesh together.

[0029] By adopting the above technical solution, in the use state, by matching and locking the annular tooth block of the lock accessory with the annular tooth groove of the meshing gear, the rotation of the meshing gear can be restricted, thereby maintaining the rotation angle of the semi-arc plate frame.

[0030] Optionally, the lock fitting has an extension pin on its side, and the connecting plate has a movable slot. The extension pin is fitted into the movable slot. The side of the extension pin away from the annular tooth block has a stop. A tension spring is connected between the stop and the connecting plate. In use, the tension spring is under tension.

[0031] By adopting the above technical solution, through the design of the extension post and the movable slot, the locking device can be movably installed on the connecting plate. In use, when the locking device abuts against the meshing gear, and the annular tooth block and annular tooth groove are matched and engaged, the stop can move away from the connecting plate and keep the tension spring in a stretched state. At this time, when the rotating rod is subjected to force and rotates unexpectedly, causing the sliding rod to move, the elastic force of the tension spring acting on the extension post can force the locking device to always abut against the annular tooth groove, maintaining the engagement of the annular tooth block and annular tooth groove. This can further reduce the possibility of unexpected changes in the installation angle of the photovoltaic panel and ensure that the photovoltaic panel maintains good power generation efficiency.

[0032] Optionally, there are two meshing gears, which are spaced apart from each other on the mounting bracket.

[0033] By adopting the above technical solution, and setting the number of meshing gears to two, after the limiting component disengages from the meshing gears, the two meshing gears serve as two fulcrums supporting the semi-arc plate frame, which helps to improve the stability of the semi-arc plate frame and reduce the possibility of arbitrary rotation of the semi-arc plate frame.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. By setting a housing component covering the rotating rod and the first plate, the rotating rod can be protected, reducing the possibility of external personnel hitting the rotating rod or the limit component being accidentally unlocked, thus maintaining the installation angle of the photovoltaic panel and ensuring that the photovoltaic panel has good power generation efficiency;

[0036] 2. By setting up a telescopic mechanism, when the photovoltaic bracket is reset from the adjustment state to the use state, the first plate can smoothly force the movable column to move downward; when the first plate leaves the movable column and moves to the outer side of the photovoltaic panel, the movable column automatically resets, and the first plate can abut against the side of the movable column, reducing the arbitrary rotation of the rotating rod, so that the installation angle of the semi-circular bracket and the photovoltaic panel can be maintained.

[0037] 3. By setting an annular tooth block and an annular tooth groove, in use, the annular tooth block of the lock accessory is matched and locked in the annular tooth groove of the meshing gear, which can restrict the rotation of the meshing gear, thereby maintaining the rotation angle of the semi-arc plate frame.

Detailed Implementation

[0049] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0050] This application discloses an adjustable solar photovoltaic bracket.

[0051] Reference Figure 1 An adjustable solar photovoltaic support structure includes a main beam 1, at least one support column 2, and at least one semi-circular plate frame 3. In this embodiment, there are multiple support columns 2 and semi-circular plate frames 3. Each support column 2 is fixed to a foundation carrier, such as the ground or roof, and all support columns 2 are arranged in a row with equidistant spacing between adjacent support columns 2. A rotating structure 4 is fixed to the top of each support column 2, and the main beam 1 is fixedly installed on the rotating structure 4, allowing the main beam 1 to rotate relative to the support column 2.

[0052] Specifically, refer to Figure 2 The rotating structure 4 includes two bearings 41 and two bushings 42. The side of each bearing 41 has a rectangular first mounting groove 411. Furthermore, the main beam 1 has a rectangular cross-section. When the two bearings 41 are fixedly connected by fasteners 43, the two first mounting grooves 411 face each other, forming a positioning space for clamping and fixing the main beam 1. The outer arc surface of each bearing 41 has an annular groove 412, and the two bushings 42 are fitted into the two annular grooves 412, allowing the two bearings 41 to rotate together within the two bushings 42. (See also...) Figure 3 The bushing 42 is also fixed to the top of the support column 2 by fasteners 43, thereby allowing the main beam 1 to be rotated and installed on the top of the support column 2.

[0053] The semi-circular frame 3 is configured as a semi-circular frame. The side of the semi-circular frame 3 is provided with a second mounting groove 38, through which the semi-circular frame 3 can be fitted onto the main beam 1. After the semi-circular frame 3 is installed, it is threadedly connected to the main beam 1 using connecting bolts 39. The connecting bolts 39 can pass through the second mounting groove 38, and the connecting bolts 39 and the inner bottom wall of the second mounting groove 38 can jointly clamp and position the main beam 1, so that the semi-circular frame 3 is firmly fixed to the main beam 1. The fixed semi-circular frame 3 is used to install photovoltaic panels. In this embodiment, there are multiple semi-circular frames 3, and all semi-circular frames 3 are spaced apart along the extension direction of the main beam 1.

[0054] Reference Figure 3 An adjustment mechanism 5 is provided between the semi-circular frame 3 and the support column 2 to adjust the angle of the semi-circular frame 3. Specifically, the adjustment mechanism 5 includes an arc-shaped rack 51 and meshing gears 52. The arc-shaped rack 51 is integrally formed on the outer arc surface of the semi-circular frame 3. A mounting bracket 21 is fixedly mounted on the side of the support column 2. There are two meshing gears 52, which are rotatably mounted on the mounting bracket 21 and spaced apart. Each meshing gear 52 meshes with the arc-shaped rack 51, thereby adjusting the installation angle of the photovoltaic panel by rotating the semi-circular frame 3. The two meshing gears 52 form two fulcrums to improve the stability of the semi-circular frame 3 and reduce the possibility of arbitrary rotation of the semi-circular frame 3.

[0055] A locking mechanism 6 is installed on the outside of the support column 2 to position the rotation angle of the semi-circular plate frame 3; see reference. Figure 4 The locking mechanism 6 includes a rotating rod 61, a first plate 62, a rocker arm 63, a second plate 64, and a sliding rod 65. The rotating rod 61 is rotatably connected to one side of the support column 2, and the axis of the rotating rod 61 is perpendicular to the extension direction of the main beam 1. The first plate 62 is fixedly sleeved on the rotating rod 61, so that the first plate 62 can rotate with the rotating rod 61.

[0056] The sliding rod 65 is movably inserted through each support column 2, and the direction of movement of the sliding rod 65 is the same as the extension direction of the main beam 1; the second plate 64 is rotatably sleeved on the sliding rod 65, and the second plate 64 and the sliding rod 65 are axially linked. See details. Figure 5 The outer circumferential surface of the sliding rod 65 is provided with an embedded groove 651. The width of the embedded groove 651 is equal to the thickness of the second plate 64. The second plate 64 can be rotatably fitted into the embedded groove 651, so that when the second plate 64 moves along the axis of the sliding rod 65, it can smoothly drive the sliding rod 65 to move together.

[0057] One end of the rocker arm component 63 is rotatably connected to the first plate 62 via a connecting shaft 632, and the axis of rotation of the connecting shaft 632 is set in the same direction as the central axis of the rotating rod 61. When the rotating rod 61 rotates, the first plate 62 can drive the rocker arm to rotate around the central axis of the rotating rod 61, so that the distance between the rocker arm component 63 and the rotating rod 61 changes.

[0058] The other end of the rocker arm component 63 is movably connected to the second plate 64 via a movable structure; specifically, the movable structure includes a strip hole 641, a through hole 631, and a connector 66. The strip hole 641 is opened through the second plate 64, and the extension direction of the strip hole 641 is in the same direction as the extension direction of the second plate 64; the through hole 631 is opened through the rocker arm component 63.

[0059] The connector 66 is rotatably inserted into the through hole 631 and the strip hole 641. One end of the connector 66 has an integrally formed end head 661, and the other end of the connector 66 is threadedly connected to a locking cap 67. Through the cooperation of the end head 661 and the locking cap 67, the limiting rocker arm component 63 and the second plate 64 are clamped together, so that the rocker arm component 63 is rotatably connected to the second plate 64, while the connector 66 can move in the strip hole 641. This enables the rocker arm component 63 to rotate smoothly and avoid obstacles when the rotating rod 61 moves, reducing interference between components and even jamming.

[0060] Back Figure 4 It should be noted that the central axis of the connector 66 is the axis of rotation of the second plate 64 and the rocker arm component 63. The central axis of the connector 66 is perpendicular to the central axis of the rotating rod 61. When the rotating rod 61 rotates and moves the rocker arm component 63, the sliding rod 65 can move together with the rocker arm component 63 through the second plate 64.

[0061] Back Figure 3 The sliding rod 65 is fixed with multiple limiting components 7, the number of which is equal to the number of the semi-circular frame 3. Each limiting component 7 is correspondingly disposed on the outside of the meshing gear 52, and is used to engage and lock with the meshing gear 52. In use, this restricts the rotation of the meshing gear 52, reduces the possibility of accidental changes in the installation angle of the photovoltaic panel, and maintains the angle of the semi-circular frame 3 and the photovoltaic panel installed on it. In adjustment mode, the limiting components 7 can disengage from the meshing gear 52, allowing operators to smoothly rotate the semi-circular frame 3 to adjust the installation angle of the photovoltaic panel, thereby ensuring that sunlight shines directly on the photovoltaic panel in different seasons and ensuring the power generation efficiency of the photovoltaic panel.

[0062] It should be noted that the usage state mentioned in this application refers to the state in which the photovoltaic panel is fixed and the angle remains unchanged, and it is able to receive solar energy and convert it into electrical energy to generate electricity; in addition, the adjustment state mentioned in this application refers to the state in which the operator can push the semi-circular plate frame 3 to rotate it, so that the operator can easily adjust the installation angle of the photovoltaic panel.

[0063] Specifically, refer to Figure 3 , Figure 6 The limiting component 7 includes a connecting plate 71 and a locking accessory 72. The connecting plate 71 is fixedly sleeved on the sliding rod 65, and a through movable slot 711 is provided on the side of the connecting plate 71. The locking accessory 72 has an integrally formed extension post 722 on its side. The cross-sectional shape of the extension post 722 is rectangular, and the outer diameter of the extension post 722 is equal to the inner diameter of the movable slot 711, so that the extension post 722 can be movably inserted into the movable slot 711. An integrally formed stop 723 is provided on the side of the extension post 722 away from the annular toothed block 721. A tension spring 73 is connected between the stop 723 and the connecting plate 71. The tension spring 73 can always generate an elastic force acting on the stop 723, forcing the stop 723 to normally abut against the connecting plate 71.

[0064] The lock fitting 72 has an annular toothed block 721 on its side, which is integrally formed with the lock fitting 72. The meshing gear 52 has an annular toothed groove 521 on its side. In use, the annular toothed block 721 can mesh with the annular toothed groove 521, thereby restricting the rotation of the meshing gear 52. At this time, the stop 723 can be spaced apart from the connecting plate 71, so that the tension spring 73 is in a stressed state. The elastic force generated by the tension spring 73 on the extension post 722 can force the annular toothed block 721 to mesh tightly with the annular toothed groove 521, further reducing the possibility of accidental changes in the installation angle of the photovoltaic panel.

[0065] Additionally, returning Figure 3 A housing component 8 is fixed to the side of the support column 2. The housing component 8 covers the rotating rod 61 and the first plate 62, protecting the rotating rod 61 and reducing the possibility of accidental rotation by external personnel. (Refer to...) Figure 7 The housing component 8 has an operating hole 81 that communicates with the interior, and the operating hole 81 is directly opposite to the rotating rod 61. A vertically sliding movable plate 82 is installed on the side of the housing component 8. The movable plate 82 has a locking hole 821, and the inner diameter of the locking hole 821 is adapted to the inner diameter of the operating hole 81. In the adjustment state, the movable plate 82 can be moved to a position where the locking hole 821 is directly opposite the operating hole 81.

[0066] The locking mechanism 6 also includes an operating lever 68 for controlling the rotation of the rotating lever 61. One end of the operating lever 68 is provided with an integrally formed spline block 681, and the other end of the operating lever 68 is fixed with a handle, which allows the operating lever 68 to be easily rotated. It should be noted that the outer diameter of the operating lever 68 is equal to the inner diameter of the operating hole 81; the end of the rotating lever 61 is provided with a spline groove 611 that mates with the spline block 681. When the locking hole 821 and the operating hole 81 are aligned, the operating lever 68 is inserted into the locking hole 821 and the operating hole 81, so that the spline block 681 matches into the spline groove 611. Rotating the operating lever 68 can smoothly drive the rotating lever 61 to rotate, thereby causing the annular tooth block 721 to disengage from the annular tooth groove 521, so that the photovoltaic bracket is in an adjusted state.

[0067] Back Figure 4 The inner bottom wall of the housing component 8 is provided with a telescopic mechanism 9, which is located on the outer side of the first plate 62; at the same time, refer to Figure 8 The telescopic mechanism 9 includes a fixed column 91, a movable column 92, and a compression spring 93. The fixed column 91 is fixed to the bottom wall of the housing component 8. The top of the fixed column 91 is provided with a movable groove 911, and the movable column 92 is movably inserted into the movable groove 911. The compression spring 93 is disposed inside the movable groove 911. One end of the compression spring 93 abuts against the bottom wall of the movable groove 911, and the other end of the compression spring 93 abuts against the movable column 92. The compression spring 93 can always generate an elastic force acting on the movable column 92, thereby forcing the movable column 92 to move away from the fixed column 91.

[0068] When the photovoltaic bracket returns from the adjustment state to the use state, the first plate 62 can abut against the movable column 92 and force the movable column 92 to move downward. At this time, the compression spring 93 is in the force-retracted state; back to Figure 4 A counterweight 621 is attached to the end of the first plate 62 furthest from the rotating rod 61. The counterweight 621, under its own weight, exerts a pulling force on the first plate 62 greater than the elastic force of the compression spring 93, allowing the first plate 62 to smoothly force the movable column 92 to retract inward, thus resetting the photovoltaic bracket to its usable state. Furthermore, after the photovoltaic bracket is reset to its usable state, the first plate 62 moves away from the movable column 92; the movable column 92 automatically resets under the elastic force of the compression spring 93, allowing the first plate 62 to rest against the side of the movable column 92, further restricting the rotation of the rotating rod 61.

[0069] Additionally, a connecting rod 921 is fixed to the side of the movable column 92, and the end of the connecting rod 921 away from the movable column 92 is fixedly connected to the movable plate 82, while referring to... Figure 7When the movable plate 82 moves to the position where the lock hole 821 is directly opposite the operating hole 81, the movable column 92 can automatically move to the bottom of the first plate 62 so that the operator can easily insert the operating lever 68 into the housing component 8 and drive the rotating lever 61 to rotate to release the lock on the adjustment mechanism 5.

[0070] It should be noted that in this embodiment, the inner diameter of the lock hole 821 is larger than the outer diameter of the operating lever 68, and the inner bottom wall of the lock hole 821 is provided with a serrated part 822. The outer peripheral surface of the operating lever 68 is partially provided with a serrated groove 682. When the operating lever 68 is rotated and the locking accessory 72 is disengaged from the meshing gear 52, the movable plate 82 naturally returns to its original position under the elastic force of the compression spring 93. The serrated part 822 can be matched and locked in the serrated groove 682, thereby restricting the rotation of the operating lever 68 and keeping the position of the locking accessory 72 maintained. After the angle of the semi-arc plate frame 3 is adjusted, the operating lever 68 is pulled out directly. Under the pulling force of the counterweight block 621, the first plate 62 can automatically force the movable column 92 to move downward, thereby automatically returning the first plate 62 to its original position, and the photovoltaic bracket can automatically be put into use.

[0071] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
