[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a single-column multi-degree-of-freedom frame-type photovoltaic support and an installation method thereof. Background Art

[0002] ‌Photovoltaic panels are power generation devices that produce direct current electricity when exposed to sunlight. They are mainly composed of photovoltaic cells, which are usually made of semiconductor materials (such as silicon).

[0003] Photovoltaic panels have significant advantages in environmental protection and energy utilization. First, photovoltaic power generation does not produce any pollutants, achieving zero emissions, which helps reduce greenhouse gas emissions and combat global warming. Second, photovoltaic panels can greatly reduce dependence on traditional power resources, especially in areas with sufficient sunshine, and can meet the power needs of households or industries, thereby saving electricity bills.

[0015] A method for installing a single-column multi-degree-of-freedom frame-type photovoltaic support comprises the following steps: Step 1: When installing the photovoltaic panels, the receiving and regulating mechanism can be driven to move to adjust the spacing between the horizontal plates. When the adjustment is completed, the photovoltaic panels can be installed on the horizontal plates; Step 2: When the direction of the photovoltaic panel needs to be adjusted, the two-way locking mechanism is controlled to move so that the hollow column can rotate freely to adjust the angle of the photovoltaic panel through the receiving frame; Step 3: The two-way locking mechanism also drives the unlocking rotating assembly to move, and drives the receiving rod to rotate through the follow-up regulating mechanism, so as to adjust the angle between the receiving frame and the hollow column through the fixing plate; Step 4: After the adjustment is completed, the position of the hollow column and the unlocking rotating assembly is locked again under the action of the two-way locking mechanism to lock the position of the photovoltaic panel.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application can adjust the angle and orientation of the photovoltaic panel according to the lighting angle and the lighting season. Specifically, when installing the photovoltaic panel, the spacing between the horizontal plates can be adjusted by the receiving and regulating mechanism so that the horizontal plates are equidistantly spread out to ensure the stability of the photovoltaic panel installation. When the photovoltaic panel is installed, the angle of the hollow column and the receiving frame can be synchronously locked under the action of the two-way locking mechanism. When the angle of the photovoltaic panel needs to be adjusted, the two-way locking mechanism can be controlled to move so that the hollow column is no longer locked. At the same time, the two-way locking mechanism can also adjust the angle of the hollow column to change the orientation of the photovoltaic panel. The two-way locking mechanism will also drive the unlocking rotating assembly to move through the follow-up regulating mechanism. Under the action of the follow-up regulating mechanism, the receiving rod is controlled to rotate to adjust the angle of the photovoltaic panel through the fixed plate and the receiving frame. When the adjustment is completed, the two-way locking mechanism is reset and the photovoltaic panel is locked again.

[0017] By controlling the sliding sleeve to move back and forth once, the angle of the supporting frame can be adjusted accordingly, and each adjustment corresponds to the changes of the four seasons. For traditional brackets, it is necessary to loosen the fastening bolts, measure the required adjustment angle, and then adjust the angle of the photovoltaic panel. Therefore, compared with traditional brackets, the present application has the advantages of simple operation, no need to measure the yaw angle, and quick self-locking effect after the angle adjustment is completed.

[0018] By controlling the equidistant expansion of the horizontal plates, photovoltaic panels of different sizes can be installed, and the supporting force of the photovoltaic panels can be balanced by the horizontal plates, thereby increasing the application range of the mounting bracket and the stability during use. During the installation process, by adjusting the spacing between the baffles, clamping force can also be provided to both sides of the photovoltaic panel, thereby assisting the installation of the photovoltaic panel.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0033] See also Figure 1 to Figure 11 In an embodiment of the present invention, a single-column multi-degree-of-freedom frame-type photovoltaic support comprises: A bottom plate 1, and a hollow column 4 rotatably mounted on the bottom plate 1, a support plate 5 is provided at the end of the hollow column 4, and a support column 2 sleeved on the hollow column 4 is provided on the bottom plate 1; Also includes: A receiving plate 11 is mounted on the support plate 5 and is symmetrically arranged. A receiving rod 15 is rotatably mounted on the receiving plate 11. A symmetrically arranged fixing plate 18 is arranged at the end of the receiving rod 15. A receiving frame 19 is arranged at the end of the fixing plate 18. A two-way locking mechanism, provided on the support column 2 and connected to the hollow column 4, for limiting the rotation of the hollow column 4; An unlocking rotating assembly is arranged on the supporting plate 5 and connected to the bidirectional locking mechanism. A follow-up regulating mechanism connected to the unlocking rotating assembly and the receiving rod 15 is arranged on the receiving plate 11. When the bidirectional locking mechanism moves, the unlocking rotating assembly can drive the receiving rod 15 to rotate through the follow-up regulating mechanism, so as to adjust the swing angle of the receiving frame 19 through the fixing plate 18. The receiving and regulating mechanism is arranged on the fixed plate 18 and connected to the receiving frame 19. A plurality of equidistantly distributed transverse plates 21 are connected to the receiving and regulating mechanism. The receiving and regulating mechanism can drive the transverse plates 21 to perform equidistant expansion or approaching movements.

[0034] Specifically, when installing the photovoltaic panel, since the size between the photovoltaic panel and the receiving frame 19 may have a certain deviation, it is necessary to adjust the position of the cross plate 21. At this time, the receiving and regulating mechanism can be driven to move to control multiple cross plates 21 to expand or move equidistantly until the cross plate 21 is adapted to the size of the photovoltaic panel. The photovoltaic panel can be installed on the cross plate 21. In order to increase the power generation efficiency of the photovoltaic panel, it is necessary to adjust the deflection angle and direction of the photovoltaic panel itself according to seasonal changes. At this time, the two-way locking mechanism can be driven to move so that the hollow column 4 is no longer locked, thereby The stop mechanism controls the hollow column 4 to deflect to the required angle. At the same time, the two-way locking mechanism will also drive the unlocking rotating assembly to move, so as to drive the receiving rod 15 to rotate through the receiving regulating mechanism, thereby adjusting the deflection angle of the receiving frame 19 through the fixed plate 18, so that the photovoltaic panel can reach the required swing angle and orientation angle. After the adjustment is completed, the two-way locking mechanism is reset and the position of the photovoltaic panel can be locked. Through the movement of the two-way locking mechanism, the photovoltaic panel can be adjusted in multiple degrees of freedom, so as to achieve efficient and fast adjustment while ensuring that the photovoltaic panel remains stable.

[0035] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 The two-way locking mechanism includes a limit tooth 3 installed at the end of the support column 2, a sliding sleeve 8 is slidably installed on the hollow column 4, a handwheel 803 is provided on the sliding sleeve 8, and a follower tooth 9 cooperating with the limit tooth 3 is provided at the end of the sliding sleeve 8. An elastic component connected with the sliding sleeve 8 is provided on the hollow column 4, wherein the elastic component includes a slide groove 401 opened on the outer wall of the circumference of the hollow column 4, and a sliding block 801 slidably connected with the slide groove 401 is provided on the inner wall of the sliding sleeve 8; it also includes a fixing ring 6 installed on the hollow column 4, and a spring 27 is sleeved on the hollow column 4, and the two ends of the spring 27 are respectively abutted against the handwheel 803 and the fixing ring 6.

[0036] In detail, in the initial state, the spring 27 is in a compressed state, so that the sliding sleeve 8 is located at the end of the stroke toward the bottom plate 1, and the sliding sleeve 8 will control the follower latch 9 and the limit latch 3 to be in an engaged state. Since the support column 2 is in a fixed state, the sliding sleeve 8 cannot rotate either. At the same time, the sliding sleeve 8 will lock the hollow column 4 through the sliding block 801 and the sliding groove 401. When the direction of the photovoltaic panel needs to be adjusted, the hand wheel 803 can be held and the sliding sleeve 8 can be driven to move along the length direction of the hollow column 4 and move in the direction away from the bottom plate 1 to compress the spring 27. The sliding sleeve 8 will also drive the follower latch 9 to move. 9 moves, so that the follower tooth 9 is separated from the limit tooth 3, so that the hollow column 4 can rotate freely. At this time, the sliding sleeve 8 can be driven to rotate by the handwheel 803, so that the hollow column 4 can be driven to rotate by the sliding block 801 and the slide groove 401, so as to drive the support plate 5 to rotate. The support plate 5 will adjust the direction of the receiving frame 19 through the receiving plate 11, the receiving rod 15 and the fixed plate 18 to adjust the direction of the photovoltaic panel. When the adjustment is completed, the force applied to the handwheel 803 is removed, the spring 27 is elastically released, and drives the sliding sleeve 8 to move toward the initial position until the follower tooth 9 is engaged with the limit tooth 3 again, and the hollow column 4 is locked again.

[0037] Preferably, the best orientation of the photovoltaic panel will change with the change of seasons. Generally, the photovoltaic panel should face due south to obtain the maximum power generation. However, in different seasons, the best orientation may be different. When the existing photovoltaic bracket is in use, the bracket angle is usually locked by bolts. When adjusting the bracket orientation, the bolts need to be loosened, and the bracket may shake during adjustment. However, when adjusting, the present application only needs to control the movement of the sliding sleeve 8. Therefore, in normal use, the spring 27 can lock the position of the sliding sleeve 8. At the same time, under the action of the follower latch 9 and the limit latch 3, the orientation of the photovoltaic panel can be locked. When the season changes, only the sliding sleeve 8 needs to be controlled to move to unlock the hollow column 4, so that it is easy to adjust the orientation of the photovoltaic panel, and the stability of the bracket during adjustment can be ensured. After the adjustment is completed, the orientation of the photovoltaic panel is automatically locked. Among them, the fixing ring 6 is also equipped with a reinforcement connecting plate 601 that is symmetrically arranged and fixedly connected to the support plate 5. Under the action of the reinforcement connecting plate 601, the stability of the support plate 5 can be increased to increase the supporting performance of the photovoltaic panel.

[0038] See also Figure 1-Figure 6The unlocking rotation 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 circumferential outer wall of the rotating rod 7, and a first limit block 802 is provided on the sliding block 801 to slide and engage with the guide groove; it also includes a turntable 10 installed at the end of the rotating rod 7, and a protrusion 1001 is provided on the turntable 10.

[0039] It should be noted that there are four groups of guide grooves equidistantly distributed around the circumference, and each group of guide grooves can be divided into four sections, 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.

[0040] In the initial state, under the action of the spring 27, the sliding sleeve 8 is located at the end of the stroke toward the base plate 1, so that the sliding block 801 is located at the end of the stroke on one side of the slide groove 401, and the first limit block 802 is located at the connection position between one of the first vertical grooves 701 and the second spiral groove 704.

[0041] When the angle of the photovoltaic panel needs to be adjusted, the sliding sleeve 8 can be controlled to move toward the fixing ring 6, thereby driving the sliding block 801 to slide along the sliding groove 401, and the sliding block 801 will also drive the first limit block 802 to move along the length direction of the first vertical groove 701. Under the action of the first limit block 802 and the first vertical groove 701, the angle of the rotating rod 7 can be locked. When the first limit 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 regulating mechanism to move through the protrusion 1001. Under the action of the follow-up regulating mechanism, the receiving rod 15 is driven to rotate, so as to adjust the angle between the photovoltaic panel and the hollow column 4 through the fixing plate 18 and the receiving frame 19.

[0042] When the first limit block 802 moves and the first spiral groove 702 is connected to the second vertical groove 703, the rotating rod 7 rotates 45°. At this time, the force applied to the hand wheel 803 is removed. Under the action of the spring 27, the sliding sleeve 8 moves toward the initial position to drive the first limit 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 limit block 802 disengages from the second vertical groove 703 and enters the second spiral groove 704, the rotating rod 7 continues to rotate, so that the angle of the photovoltaic panel continues to change.

[0043] When the first limit block 802 moves to the connection position of the next first vertical groove 701 and the second spiral groove 704, the rotating rod 7 rotates 45° again. Through the reciprocating movement of the sliding sleeve 8 once, the rotating rod 7 can be controlled to rotate a quarter of a turn to adjust the angle of the photovoltaic panel. When the adjustment is completed, under the action of the first limit block 802 and the first vertical groove 701, the angle of the rotating rod 7 can be locked, thereby ensuring that the angle of the photovoltaic panel is automatically locked after the angle adjustment is completed.

[0044] Preferably, through the cooperation between the guide groove and the first limit 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, it can be unlocked first and then adjusted, and after the adjustment is completed, the angle of the photovoltaic panel can be locked again.

[0045] See also Figure 1-Figure 4 , Figure 8-Figure 10 The follow-up regulating mechanism includes a guide column 12 installed on the receiving plate 11, a guide sleeve 13 is slidably installed on the guide column 12, a movable plate 14 is provided on the side wall of the guide sleeve 13, a groove 1401 is provided on the movable plate 14 and is slidably engaged with the protrusion 1001, a follower component connected with the receiving rod 15 is provided on the guide sleeve 13, wherein the follower component includes a third spiral groove 1501 provided on the receiving rod 15, a movable sleeve 16 is slidably installed on the receiving rod 15, a second limit block 1601 is slidably engaged with the third spiral groove 1501 is provided on the inner wall of the movable sleeve 16, and a follower ring 17 fixedly connected with the guide sleeve 13 is provided on the movable sleeve 16.

[0046] Further, in the case of the photovoltaic panel being in summer, in the initial state, under the action of the protrusion 1001 and the groove 1401, the movable plate 14 is located at the end of the stroke toward one of the receiving plates 11, so that the movable sleeve 16 is controlled to be located at the end of the stroke on the side of the receiving rod 15 through the guide sleeve 13 and the follower ring 17. At this time, the second limit block 1601 is located at the end of the stroke on the 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, so that the photovoltaic panel can receive the maximum radiation area of ​​sunlight. When it is autumn, it is necessary to increase the angle between the receiving frame 19 and the hollow column 4. At this time, under the action of the sliding sleeve 8, the first limit block 802 is driven to slide in the guide groove through the sliding block 801, so that the rotating rod 7 is unlocked and rotated 45° first, thereby driving the turntable 10 to rotate. The turntable 10 will also drive the movable plate 14 to move through the protrusion 1001 and the groove 1401 to drive The guide sleeve 13 moves along the length direction of the guide column 12, and the guide sleeve 13 also drives the movable sleeve 16 to move along the length direction of the receiving rod 15 through the follower ring 17 to control the second limit block 1601 to slide in the third spiral groove 1501. Since the guide sleeve 13 and the guide column 12 have a guiding function, it can be ensured that the movable sleeve 16 will not deflect during movement. Therefore, under the action of the second limit block 1601 and the third spiral groove 1501, the receiving rod 15 rotates to pass The angle between the receiving frame 19 and the hollow column 4 is reduced through the fixed plate 18. After the sliding sleeve 8 is reset, the rotating rod 7 is rotated 45° again. At this time, the guide sleeve 13 moves to the center position of the two receiving plates 11, so that the second limit block 1601 moves to the middle position of the third spiral groove 1501, thereby reducing the angle between the receiving frame 19 and the hollow column 4 again. At this time, the angle adjustment of the photovoltaic panel is completed, and under the action of the first limit block 802 and the guide groove, the rotating rod 7 is locked again.

[0047] Preferably, when winter comes, the angle between the receiving frame 19 and the hollow column 4 needs to be reduced again. At this time, the sliding sleeve 8 reciprocates again, so that the turntable 10 rotates a quarter of a turn again, so that the second limit block 1601 moves to the end of the stroke on the other side of the third spiral groove 1501. When spring comes, the angle between the receiving frame 19 and the hollow column 4 needs to be increased, and the sliding sleeve 8 reciprocates again once, so that the second limit block 1601 returns to the middle position of the third spiral groove 1501 again. When summer comes again, the turntable 10 is just After one rotation, the second limit block 1601 returns to the initial position of the third spiral groove 1501. Through the above operation, when the seasons change, the sliding sleeve 8 can be driven to reciprocate once to adjust the angle of the supporting frame 19 accordingly, and each adjustment corresponds to the changes of the four seasons. For traditional brackets, it is necessary to loosen the fastening bolts, measure the required adjustment angle, and then adjust the angle of the photovoltaic panel. Therefore, compared with traditional brackets, the present application has the advantages of simple operation, no need to measure the yaw angle, and quick self-locking after the angle adjustment is completed.

[0048] See also Figure 1 , Figure 2 , Figure 4 , Figure 8 , Fig.11 The receiving and regulating mechanism includes a second card slot 1902 which is symmetrically arranged on the receiving frame 19, and a plurality of movable blocks 20 which are equidistantly distributed are slidably installed in the second card slot 1902, and the movable blocks 20 are fixedly connected to the cross plate 21, and a limiting column 23 is arranged on the movable block 20, and a sliding component connected to the limiting column 23 is arranged on the receiving frame 19, wherein the sliding component includes a first card slot 1901 which is symmetrically arranged on the receiving frame 19, and a sliding plate is slidably installed in the first card slot 1901 24, a plurality of inclined grooves 2401 are provided on the sliding plate 24, and the inclined grooves 2401 are slidably connected to the limiting column 23, and a bidirectional movable structure connected to the sliding plate 24 is provided on the fixed plate 18, and the bidirectional movable structure mentioned above includes a bidirectional screw rod 25 rotatably mounted on the fixed plate 18, and a symmetrically arranged threaded sleeve 26 is movably mounted on the bidirectional screw rod 25, and the threaded sleeve 26 is threadedly matched with the bidirectional screw rod 25, and a limiting ring 2601 fixedly connected to the sliding plate 24 is provided on the threaded sleeve 26.

[0049] Furthermore, there are multiple inclined grooves 2401, and the spacing between the ends of each inclined groove 2401 that are close to each other is the same, and the spacing between the ends of each inclined groove 2401 that are far away from each other is also the same. There are four groups of cross plates 21, and baffles 22 are installed on two cross plates 21 that are far away from each other. In the initial state, under the action of the two-way screw rod 25, the spacing between the two sliding plates 24 is maximized, so that the limiting column 23 is located at the end with a smaller spacing between the ends of the inclined groove 2401. Under the action of the inclined groove 2401 and the limiting column 23, the spacing between adjacent movable blocks 20 is equal and the spacing is the smallest. Therefore, the adjacent cross plates 21 are equidistant and the spacing is the smallest. When it is necessary to install the photovoltaic panel, at this time, the two-way screw rod 25 rotates to move the two threaded sleeves 26, thereby driving the sliding plate 24 along the length of the first slot 1901 through the limiting ring 2601. The first card slot 1901 and the sliding plate 24 have a guiding function, so that the threaded sleeve 26 moves along the length direction of the bidirectional screw rod 25 and will not rotate with the bidirectional screw rod 25. The sliding plate 24 will also drive the inclined slot 2401 to move, so that the limiting column 23 slides along the length direction of the inclined slot 2401. Under the action of the limiting column 23, multiple movable blocks 20 are controlled to slide along the length direction of the second card slot 1902, and perform equidistant expansion movements, so that the spacing between the cross plates 21 is increased to increase the spacing between the two baffles 22. When the spacing between the two baffles 22 is equivalent to that of the photovoltaic panel, the photovoltaic panel can be installed between the two baffles 22 at this time, and the photovoltaic panel and the cross plate 21 are fixedly connected by bolts or the like. Under the action of the baffle 22, supporting force can be provided to both sides of the photovoltaic panel to ensure the best stability of the photovoltaic panel during installation.

[0050] Preferably, by controlling the horizontal plates 21 to be equidistantly spread out, photovoltaic panels of different sizes can be installed, and the supporting force on the photovoltaic panels can be balanced by the horizontal plates 21, thereby increasing the scope of application of the mounting bracket and its stability during use. In addition, 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 the installation of the photovoltaic panels.

[0051] A method for installing a single-column multi-degree-of-freedom frame-type photovoltaic support comprises the following steps: Step 1: When installing the photovoltaic panel, the receiving and regulating mechanism can be driven to move 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; Step 2: When the direction of the photovoltaic panel needs to be adjusted, the two-way locking mechanism is controlled to move so that the hollow column can rotate freely to adjust the angle of the photovoltaic panel through the receiving frame 19; Step 3: The two-way locking mechanism also drives the unlocking rotating assembly to move, and drives the receiving rod 15 to rotate through the follow-up regulating mechanism, so as to adjust the angle between the receiving frame 19 and the hollow column 4 through the fixing plate 18; Step 4: After the adjustment is completed, the position of the hollow column and the unlocking rotating assembly is locked again under the action of the two-way locking mechanism to lock the position of the photovoltaic panel.
