Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically a single-column, multi-degree-of-freedom frame-type photovoltaic support and its installation method. Background Technology

[0002] A photovoltaic panel is a power generation device that generates direct current when exposed to sunlight. It is mainly composed of photovoltaic cells, which are usually made of semiconductor materials (such as silicon).

[0003] Photovoltaic panels offer significant advantages in environmental protection and energy utilization. First, photovoltaic power generation produces no pollutants, achieving zero emissions and helping to reduce greenhouse gas emissions and combat global warming. Second, photovoltaic panels can greatly reduce reliance on traditional electricity sources, especially in areas with abundant sunshine, meeting the electricity needs of households or industries and thus saving on electricity bills.

[0004] When installing photovoltaic panels, they are usually installed using photovoltaic brackets. After the photovoltaic panels are installed, they are usually fixed by bolts or welding. When the seasons change, the optimal angle of sunlight will also change. If the angle of the photovoltaic panels needs to be adjusted, the bolts need to be loosened. Frequent adjustments may cause the bracket structure to loosen, and the tilt angle of the photovoltaic panels also needs to be measured before adjustment, which increases the difficulty of installation. Summary of the Invention

[0005] The purpose of this invention is to provide a single-column, multi-degree-of-freedom frame-type photovoltaic support and its installation method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A single-column, multi-degree-of-freedom frame-type photovoltaic support system includes:

[0008] A base plate, and a hollow column rotatably mounted on the base plate, wherein a support plate is provided at the end of the hollow column, and a support column sleeved on the hollow column is provided on the base plate;

[0011] A two-way locking mechanism is provided on the support column and connected to the hollow column to restrict the rotation of the hollow column;

[0012] An unlocking rotating component is disposed on the support plate and connected to the bidirectional locking mechanism. The receiving plate is provided with a follow-up adjustment mechanism connected to the unlocking rotating component and the receiving rod. When the bidirectional locking mechanism moves, the unlocking rotating component can drive the receiving rod to rotate through the follow-up adjustment mechanism, so as to adjust the sway angle of the receiving frame through the fixed plate.

[0013] A receiving and control mechanism is set on the fixed plate and connected to the receiving frame. Multiple equally spaced horizontal plates are connected to the receiving and control mechanism, which can drive the horizontal plates to move equidistantly or close together.

[0015] As a further embodiment of the present invention: the elastic component includes a groove formed on the outer circumference of the hollow column, and the inner wall of the sliding sleeve is provided with a sliding block that is slidably connected to the groove;

[0016] It also includes a fixing ring installed on the hollow column, and a spring is sleeved on the hollow column, with the two ends of the spring abutting against the handwheel and the fixing ring respectively.

[0017] As a further embodiment of the present invention: the unlocking rotating assembly includes a rotating rod rotatably mounted on the support plate and slidably connected to the hollow column, a guide groove is provided on the outer circumferential wall of the rotating rod, and a first limiting block is provided on the sliding block to slidably engage with the guide groove;

[0018] It also includes a turntable mounted on the end of the rotating rod, the turntable having protrusions.

[0019] As a further embodiment of the present invention: the follow-up control mechanism includes a guide post mounted on the receiving plate, a guide sleeve slidably mounted on the guide post, a movable plate provided on the side wall of the guide sleeve, a groove provided on the movable plate that slidably engages with the protrusion, and a driven component connected to the receiving rod provided on the guide sleeve.

[0020] As a further embodiment of the present invention: the driven component includes a third spiral groove formed on the receiving rod, a movable sleeve is slidably mounted on the receiving rod, a second limiting block is provided on the inner wall of the movable sleeve to slidably engage with the third spiral groove, and a follower ring is provided on the movable sleeve to be fixedly connected to the guide sleeve.

[0021] As a further embodiment of the present invention: the receiving and control mechanism includes a second slot formed on the receiving frame and arranged symmetrically, a plurality of movable blocks slidably installed in the second slot and distributed at equal intervals, the movable blocks being fixedly connected to the cross plate, the movable blocks being provided with limit posts, and the receiving frame being provided with a sliding component connected to the limit posts.

[0022] As a further embodiment of the present invention: the sliding component includes a first slot formed on the receiving frame and arranged symmetrically, a sliding plate is slidably installed in the first slot, a plurality of inclined slots are formed on the sliding plate, the inclined slots are slidably connected to the limiting post, and a bidirectional moving structure connected to the sliding plate is provided on the fixing plate.

[0023] As a further embodiment of the present invention: the bidirectional moving structure includes a bidirectional lead screw rotatably mounted on the fixed plate, and symmetrically arranged threaded sleeves are movably mounted on the bidirectional lead screw. The threaded sleeves are threadedly engaged with the bidirectional lead screw, and a limiting ring is provided on the threaded sleeves that is fixedly connected to the sliding plate.

[0024] An installation method for a single-column, multi-degree-of-freedom frame-type photovoltaic support includes the following steps:

[0025] Step 1: When installing photovoltaic panels, the receiving and regulating mechanism can be driven to adjust the spacing between the horizontal plates. After adjustment, the photovoltaic panels can be installed on the horizontal plates.

[0026] Step 2: When it is necessary to adjust the direction of the photovoltaic panel, control the movement of the two-way locking mechanism so that the hollow column can rotate freely, thereby adjusting the angle of the photovoltaic panel through the supporting frame;

[0027] Step 3: The two-way locking mechanism will also drive the unlocking rotating component to move, and drive the receiving rod to rotate through the follow-up adjustment mechanism, so as to adjust the angle between the receiving frame and the hollow column through the fixed plate;

[0028] Step 4: After the adjustment is completed, the position of the hollow column and the unlocking rotating component is locked again under the action of the two-way locking mechanism to lock the position of the photovoltaic panel.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can adjust the angle and orientation of the photovoltaic panel according to the angle of sunlight and the season of sunlight. Specifically, when installing the photovoltaic panel, the spacing between the horizontal plates can be adjusted by the receiving and adjusting mechanism to make the horizontal plates unfold at equal intervals, so as to ensure the stability of the photovoltaic panel installation. After the photovoltaic panel is installed, the angle of the hollow column and the receiving frame can be locked simultaneously under the action of the bidirectional locking mechanism. When it is necessary to adjust the angle of the photovoltaic panel, the movement of the bidirectional locking mechanism can be controlled so that the hollow column is no longer locked. At the same time, the bidirectional locking mechanism can also adjust the angle of the hollow column to change the orientation of the photovoltaic panel. The bidirectional locking mechanism will also drive the unlocking rotating component to move, so as to control the rotation of the receiving rod under the action of the following adjusting mechanism, so as to adjust the angle of the photovoltaic panel through the fixing plate and the receiving frame. After the adjustment is completed, the bidirectional locking mechanism resets and locks the photovoltaic panel again.

[0030] By controlling the reciprocating motion of the sliding sleeve once, the angle of the supporting frame can be adjusted accordingly, and each adjustment corresponds to the changes of the four seasons. In contrast, traditional brackets require loosening the fastening bolts, measuring the required adjustment angle, and then adjusting the angle of the photovoltaic panel. Therefore, compared with traditional brackets, this application has the advantages of simple operation, no need to measure the sway angle, and quick self-locking after the angle adjustment is completed.

[0031] By controlling the horizontal plates to unfold at equal intervals, photovoltaic panels of different sizes can be installed. The horizontal plates balance the supporting force on the photovoltaic panels, thereby increasing the applicability and stability of this mounting bracket. Furthermore, during the installation process, the spacing between the baffles can be adjusted to provide clamping force on both sides of the photovoltaic panels, thus assisting in the installation of the photovoltaic panels.

[0044] 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.

[0045] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0046] Please see Figures 1-11 In this embodiment of the invention, a single-column multi-degree-of-freedom frame-type photovoltaic support includes:

[0047] The base plate 1 and the hollow column 4 rotatably mounted on the base plate 1, the hollow column 4 having a support plate 5 at its end, and the base plate 1 having a support column 2 sleeved on the hollow column 4.

[0048] Also includes:

[0049] A receiving plate 11 is installed on the support plate 5 and is symmetrically arranged. A receiving rod 15 is rotatably installed on the receiving plate 11. A fixing plate 18 is symmetrically arranged at the end of the receiving rod 15. A receiving frame 19 is provided at the end of the fixing plate 18.

[0050] A two-way locking mechanism is provided on the support column 2 and connected to the hollow column 4 to restrict the rotation of the hollow column 4;

[0051] An unlocking rotating component is provided on the support plate 5 and connected to the bidirectional locking mechanism. The receiving plate 11 is provided with a follow-up adjustment mechanism connected to the unlocking rotating component and the receiving rod 15. When the bidirectional locking mechanism moves, the unlocking rotating component can drive the receiving rod 15 to rotate through the follow-up adjustment mechanism, so as to adjust the sway angle of the receiving frame 19 through the fixed plate 18.

[0052] A receiving and control mechanism is set on the fixed plate 18 and connected to the receiving frame 19. Multiple equally spaced horizontal plates 21 are connected to the receiving and control mechanism. The receiving and control mechanism can drive the horizontal plates 21 to move equidistantly or close together.

[0053] Specifically, during photovoltaic panel installation, since there may be some dimensional deviation between the photovoltaic panel and the supporting frame 19, the position of the horizontal plate 21 needs to be adjusted. At this time, the supporting control mechanism can be driven to move, controlling multiple horizontal plates 21 to unfold or move closer together at equal intervals until the dimensions of the horizontal plate 21 and the photovoltaic panel are adapted. Then, the photovoltaic panel can be installed on the horizontal plate 21. In order to increase the power generation efficiency of the photovoltaic panel, the tilt angle and orientation of the photovoltaic panel need to be adjusted according to seasonal changes. At this time, the bidirectional locking mechanism can be driven to move, so that the hollow column 4 is no longer locked, thereby achieving bidirectional locking. The locking mechanism controls the hollow column 4 to deflect to the required angle. At the same time, the bidirectional locking mechanism also drives the unlocking rotating component to move, so as to drive the receiving rod 15 to rotate through the receiving adjustment mechanism. This allows the fixed plate 18 to adjust the deflection angle of the receiving frame 19, so that the photovoltaic panel can reach the required tilt angle and orientation angle. After the adjustment is completed, the bidirectional locking mechanism resets and can also lock the position of the photovoltaic panel. By moving the bidirectional locking mechanism, the photovoltaic panel can be adjusted in multiple degrees of freedom, so as to achieve efficient and fast adjustment while ensuring the stability of the photovoltaic panel.

[0054] Please see Figure 1 , Figure 2 , Figure 6 , Figure 7 The bidirectional locking mechanism includes a limiting tooth 3 installed at the end of the support column 2, a sliding sleeve 8 slidably installed on the hollow column 4, a handwheel 803 provided on the sliding sleeve 8, a follower tooth 9 that cooperates with the limiting tooth 3 at the end of the sliding sleeve 8, an elastic component connected to the sliding sleeve 8 provided on the hollow column 4, wherein the elastic component includes a groove 401 formed on the outer circumference of the hollow column 4, a sliding block 801 slidably connected to the groove 401 provided on the inner wall of the sliding sleeve 8; it also includes a fixing ring 6 installed on the hollow column 4, a spring 27 sleeved on the hollow column 4, and the two ends of the spring 27 abutting against the handwheel 803 and the fixing ring 6 respectively.

[0055] In detail, initially, spring 27 is compressed, causing the sliding sleeve 8 to reach the end of its stroke towards the base plate 1. The sliding sleeve 8 controls the follower tooth 9 to engage with the limit tooth 3. Since the support column 2 is fixed, the sliding sleeve 8 cannot rotate. Simultaneously, the sliding sleeve 8 locks the hollow column 4 via the sliding block 801 and the groove 401. When adjusting the orientation of the photovoltaic panel, the handwheel 803 can be held, causing the sliding sleeve 8 to move along the length of the hollow column 4 and away from the base plate 1, thus compressing spring 27. The sliding sleeve 8 also drives the follower tooth... The movement of the follower tooth 9 separates from the limiting tooth 3, allowing the hollow column 4 to rotate freely. At this time, the sliding sleeve 8 can be driven to rotate via the handwheel 803, which in turn drives the hollow column 4 to rotate via the sliding block 801 and the slide groove 401, thereby causing the support plate 5 to rotate. The support plate 5 will adjust the orientation of the receiving frame 19 via the receiving plate 11, the receiving rod 15, and the fixing plate 18 to adjust the orientation of the photovoltaic panel. After the adjustment is completed, the force applied to the handwheel 803 is removed, the spring 27 is released elastically, and the sliding sleeve 8 is driven to move towards the initial position until the follower tooth 9 engages with the limiting tooth 3 again, thus locking the hollow column 4 again.

[0056] Preferably, the optimal orientation of the photovoltaic panel changes with the seasons. Typically, the photovoltaic panel should face due south to maximize power generation. However, the optimal orientation may vary in different seasons. Existing photovoltaic supports usually lock the bracket angle with bolts. Adjusting the bracket orientation requires loosening the bolts, which can cause the bracket to wobble. In this application, adjustment is achieved simply by controlling the movement of the sliding sleeve 8. Therefore, during normal use, the spring 27 locks the position of the sliding sleeve 8. Simultaneously, the orientation of the photovoltaic panel is locked by the action of the follower tooth 9 and the limit tooth 3. When the season changes, simply controlling the movement of the sliding sleeve 8 unlocks the hollow column 4, thus facilitating the adjustment of the photovoltaic panel orientation while ensuring the stability of the bracket during adjustment. After adjustment, the photovoltaic panel orientation is automatically locked. Furthermore, the fixing ring 6 is also equipped with symmetrically arranged reinforcing connecting plates 601 fixedly connected to the support plate 5. The reinforcing connecting plates 601 increase the stability of the support plate 5, thereby enhancing the support performance for the photovoltaic panel.

[0057] Please see Figures 1-6The unlocking rotating assembly includes a rotating rod 7 rotatably mounted on the support plate 5 and slidably connected to the hollow column 4. A guide groove is provided on the outer circumferential wall of the rotating rod 7. A first limiting block 802 is provided on the sliding block 801 and slidably engaged with the guide groove. It also includes a turntable 10 installed at the end of the rotating rod 7. A protrusion 1001 is provided on the turntable 10.

[0058] It should be noted that there are four groups of guide grooves distributed equidistantly around the circumference, and each group of guide grooves can be divided into four segments, namely the first vertical groove 701, the first spiral groove 702, the second vertical groove 703, and the second spiral groove 704. The ends of the first vertical groove 701, the first spiral groove 702, the second vertical groove 703, and the second spiral groove 704 are connected to each other in sequence. The pitch and the number of spiral turns of the first spiral groove 702 and the second spiral groove 704 are equal, and the number of spiral turns of the first spiral groove 702 and the second spiral groove 704 is one-eighth of a turn.

[0059] In the initial state, under the action of spring 27, the sliding sleeve 8 is located at the end of its stroke in the direction of the base plate 1, so that the sliding block 801 is located at the end of its stroke on one side of the slide groove 401, and the first limiting block 802 is located at the connection position between one of the first vertical grooves 701 and the second spiral groove 704.

[0060] When the angle of the photovoltaic panel needs to be adjusted, the sliding sleeve 8 can be controlled to move towards the fixed ring 6, thereby driving the sliding block 801 to slide along the groove 401. The sliding block 801 will also drive the first limiting block 802 to move along the length direction of the first vertical groove 701. Under the action of the first limiting block 802 and the first vertical groove 701, the angle of the rotating rod 7 can be locked. When the first limiting block 802 disengages from the first vertical groove 701 and enters the first spiral groove 702, the rotating rod 7 rotates, thereby driving the turntable 10 to move, so as to drive the follow-up adjustment mechanism to move through the protrusion 1001. Under the action of the follow-up adjustment mechanism, the receiving rod 15 is driven to rotate, so as to adjust the included angle between the photovoltaic panel and the hollow column 4 through the fixed plate 18 and the receiving frame 19.

[0061] When the first limiting block 802 moves and the first spiral groove 702 is in the connected position with the second vertical groove 703, the rotating rod 7 rotates 45°. At this time, the force applied to the handwheel 803 is removed, and under the action of the spring 27, the sliding sleeve 8 moves toward the initial position to drive the first limiting block 802 to slide along the length direction of the second vertical groove 703. During this process, the rotating rod 7 will not rotate. When the first limiting block 802 disengages from the second vertical groove 703 and enters the second spiral groove 704, the rotating rod 7 continues to rotate, causing the angle of the photovoltaic panel to continue to change.

[0062] When the first limiting block 802 moves to the position where the first vertical groove 701 and the second spiral groove 704 are connected, the rotating rod 7 rotates 45° again and reciprocates once through the sliding sleeve 8. This controls the rotating rod 7 to rotate a quarter turn to adjust the angle of the photovoltaic panel. After the adjustment is completed, the angle of the rotating rod 7 can be locked under the action of the first limiting block 802 and the first vertical groove 701, thereby ensuring the effect of automatically locking the angle of the photovoltaic panel after the angle adjustment is completed.

[0063] Preferably, by cooperating with the guide groove and the first limiting block 802, the angle of the photovoltaic panel can be locked when the photovoltaic panel is in normal use. When adjusting the angle of the photovoltaic panel, the angle can be unlocked first and then adjusted, and the angle of the photovoltaic panel can be locked again after the adjustment is completed.

[0064] Please see Figures 1-4 , Figures 8-10 The follow-up control mechanism includes a guide post 12 mounted on the receiving plate 11, a guide sleeve 13 slidably mounted on the guide post 12, a movable plate 14 provided on the side wall of the guide sleeve 13, a groove 1401 provided on the movable plate 14 that slidably engages with the protrusion 1001, a driven component provided on the guide sleeve 13 that is connected to the receiving rod 15, wherein the driven component includes a third spiral groove 1501 provided on the receiving rod 15, a movable sleeve 16 slidably mounted on the receiving rod 15, a second limiting block 1601 provided on the inner wall of the movable sleeve 16 that slidably engages with the third spiral groove 1501, and a follow-up ring 17 fixedly connected to the guide sleeve 13 provided on the movable sleeve 16.

[0065] Furthermore, taking the photovoltaic panel in summer as an example, in the initial state, under the action of the protrusion 1001 and the groove 1401, the movable plate 14 is positioned at the end of its stroke towards one of the receiving plates 11. The guide sleeve 13 and the follower ring 17 control the movable sleeve 16 to be positioned at the end of its stroke on one side of the receiving rod 15. At this time, the second limiting block 1601 is positioned at the end of its stroke on one side of the third spiral groove 1501. Under the action of the receiving rod 15 and the fixed plate 18, the angle between the receiving frame 19 and the hollow column 4 is minimized, maximizing the area of ​​sunlight received by the photovoltaic panel. When autumn arrives, the angle between the receiving frame 19 and the hollow column 4 needs to be increased. At this time, under the action of the sliding sleeve 8, the sliding block 801 drives the first limiting block 802 to slide in the guide groove, unlocking the rotating rod 7 and causing it to rotate 45°, thereby driving the turntable 10 to rotate. The turntable 10 also drives the movable plate 14 to move through the protrusion 1001 and the groove 1401, thus driving... The guide sleeve 13 moves along the length of the guide post 12. The guide sleeve 13 also drives the movable sleeve 16 to move along the length of the receiving rod 15 via the follower ring 17, thereby controlling the second limiting block 1601 to slide within the third spiral groove 1501. Since the guide sleeve 13 and guide post 12 provide guidance, they ensure that the movable sleeve 16 does not deflect during movement. Therefore, under the action of the second limiting block 1601 and the third spiral groove 1501, the receiving rod 15 rotates to allow passage. The angle between the supporting frame 19 and the hollow column 4 is reduced by the fixed plate 18. After the sliding sleeve 8 is reset, the rotating rod 7 rotates 45° again. At this time, the guide sleeve 13 moves to the center position of the two supporting plates 11, so that the second limiting block 1601 moves to the middle position of the third spiral groove 1501, thereby reducing the angle between the supporting frame 19 and the hollow column 4 again. At this time, the photovoltaic panel angle adjustment is completed. Under the action of the first limiting block 802 and the guide groove, the rotating rod 7 is locked again.

[0066] Preferably, when winter arrives, the angle between the supporting frame 19 and the hollow column 4 needs to be reduced again. At this time, the sliding sleeve 8 reciprocates once more, causing the turntable 10 to rotate another quarter turn, so that the second limiting block 1601 moves to the end of its stroke on the other side of the third spiral groove 1501. When spring arrives, the angle between the supporting frame 19 and the hollow column 4 needs to be increased. The sliding sleeve 8 reciprocates once more, causing the second limiting block 1601 to return to the middle position of the third spiral groove 1501. When summer arrives again, the turntable 10 is just... Rotating one full turn causes the second limit block 1601 to return to the initial position of the third spiral groove 1501. Through the above operation, the sliding sleeve 8 can be driven to reciprocate once during seasonal changes, thereby adjusting the angle of the supporting frame 19 accordingly. Each adjustment corresponds to the four seasons. In contrast, traditional brackets require loosening the fastening bolts, measuring the required adjustment angle, and then adjusting the photovoltaic panel angle. Therefore, compared with traditional brackets, this application has the advantages of simple operation, no need to measure the sway angle, and quick self-locking after the angle adjustment is completed.

[0067] Please see Figure 1 , Figure 2 , Figure 4 , Figure 8 , Figure 11 The receiving and adjusting mechanism includes a second slot 1902 symmetrically arranged on the receiving frame 19. Multiple movable blocks 20 equidistantly distributed are slidably installed in the second slot 1902. The movable blocks 20 are fixedly connected to the horizontal plate 21. Limiting posts 23 are provided on the movable blocks 20. A sliding assembly connected to the limiting posts 23 is provided on the receiving frame 19. The sliding assembly includes a first slot 1901 symmetrically arranged on the receiving frame 19. A sliding plate is slidably installed in the first slot 1901. 24. The sliding plate 24 is provided with a plurality of inclined grooves 2401, the inclined grooves 2401 being slidably connected to the limiting post 23. The fixed plate 18 is provided with a bidirectional moving structure connected to the sliding plate 24. The aforementioned bidirectional moving structure includes a bidirectional lead screw 25 rotatably mounted on the fixed plate 18. Threaded sleeves 26 are symmetrically arranged and movably mounted on the bidirectional lead screw 25. The threaded sleeves 26 are threadedly engaged with the bidirectional lead screw 25. A limiting ring 2601 fixedly connected to the sliding plate 24 is provided on the threaded sleeves 26.

[0068] Furthermore, multiple inclined slots 2401 are provided. The distance between the ends of each inclined slot 2401 that are close to each other is the same, and the distance between the ends of each inclined slot 2401 that are far from each other is also the same. Four sets of horizontal plates 21 are provided, and baffles 22 are installed on the two horizontal plates 21 that are far from each other. In the initial state, under the action of the bidirectional screw 25, the distance between the two sliding plates 24 is maximized, so that the limiting post 23 is located at the end of the inclined slot 2401 with the smaller distance. Under the action of the inclined slot 2401 and the limiting post 23, the distance between adjacent moving blocks 20 is equal and the distance is minimized. Therefore, the adjacent horizontal plates 21 are equidistant and the distance is minimized. When it is necessary to install photovoltaic panels, the bidirectional screw 25 rotates, causing the two threaded sleeves 26 to move, thereby driving the sliding plate 24 along the length of the first slot 1901 through the limiting ring 2601. The sliding direction, the first slot 1901 and the sliding plate 24 have a guiding function, so that the threaded sleeve 26 moves along the length direction of the double-acting screw 25 and does not rotate with the double-acting screw 25. The sliding plate 24 also drives the inclined groove 2401 to move, so that the limiting post 23 slides along the length direction of the inclined groove 2401. Under the action of the limiting post 23, multiple movable blocks 20 are controlled to slide along the length direction of the second slot 1902 and make equidistant unfolding movements, so that the distance between the horizontal plates 21 increases, thereby increasing the distance between the two baffles 22. When the distance between the two baffles 22 is equivalent to that of the photovoltaic panel, the photovoltaic panel can be installed between the two baffles 22 and fixedly connected to the horizontal plate 21 by bolts or other means. Under the action of the baffles 22, the support force on both sides of the photovoltaic panel can be provided to ensure the optimal stability of the photovoltaic panel during installation.

[0069] Preferably, by controlling the horizontal plates 21 to unfold at equal intervals, photovoltaic panels of different sizes can be installed, and the horizontal plates 21 balance the supporting force on the photovoltaic panels, thereby increasing the applicability and stability of this mounting bracket. Furthermore, during the installation process, by adjusting the spacing between the baffles 22, clamping force can be provided to both sides of the photovoltaic panels, thereby assisting in the installation of the photovoltaic panels.

[0070] An installation method for a single-column, multi-degree-of-freedom frame-type photovoltaic support includes the following steps:

[0071] Step 1: When installing the photovoltaic panel, the receiving and regulating mechanism can be driven to adjust the spacing between the horizontal plates 21. After the adjustment is completed, the photovoltaic panel can be installed on the horizontal plate 21.

[0072] Step 2: When it is necessary to adjust the direction of the photovoltaic panel, control the movement of the bidirectional locking mechanism so that the hollow column can rotate freely, so as to adjust the angle of the photovoltaic panel through the supporting frame 19;

[0073] Step 3: The bidirectional locking mechanism will also drive the unlocking rotating component to move, and drive the receiving rod 15 to rotate through the follow-up adjustment mechanism, so as to adjust the angle between the receiving frame 19 and the hollow column 4 through the fixing plate 18.

[0074] Step 4: After the adjustment is completed, the position of the hollow column and the unlocking rotating component is locked again under the action of the two-way locking mechanism to lock the position of the photovoltaic panel.

[0075] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0076] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
