Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and specifically to a wind-resistant and earthquake-resistant self-balancing photovoltaic bracket and an assembly method thereof. Background Art

[0002] The use of photovoltaic panels not only has significant environmental and economic benefits, but also promotes technological innovation and social development. By reducing dependence on fossil fuels, lowering energy costs, enhancing energy independence, and promoting employment, photovoltaic panels provide important support for achieving sustainable development goals.

[0003] To ensure the power generation efficiency of photovoltaic panels, their installation locations are generally in areas without external object obstruction, such as rooftops, water surfaces, plateaus, etc. These areas all have a common characteristic, that is, the natural wind force is relatively large. In order to enable photovoltaic panels to have better power generation efficiency, existing photovoltaic panel brackets all have the ability to adjust the angle within a certain range. Although this can further improve the power generation efficiency of photovoltaic panels, it also has certain drawbacks. The main problem is that in order to finely adjust the angle of the photovoltaic panel, the photovoltaic panel needs to be rotatably connected to the photovoltaic panel bracket, that is, there is a rotating shaft between the two. When the external wind force acts on the photovoltaic panel, the acting force will be transmitted to this rotating shaft, and excessive wind force is likely to cause the risk of deformation or even fracture of this rotating shaft, affecting the stable operation of the photovoltaic panel. Summary of the Invention

[0004] The purpose of the present invention is to provide a wind-resistant and earthquake-resistant self-balancing photovoltaic bracket and an assembly method thereof to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A wind-resistant and earthquake-resistant self-balancing photovoltaic bracket, comprising: A support frame, on which a pitching bracket with an adjustable pitching angle is arranged, and a trigger bracket is connected to the pitching bracket; A connecting frame, rotatably installed on the pitching bracket, multiple groups of parallel photovoltaic panel bodies are rotatably installed on the connecting frame, and a contact wheel is rotatably installed on the side of the connecting frame; An elastic support assembly, connecting the pitching bracket, and a holding position and two release positions are formed on the elastic support assembly. When wind force exceeding a predetermined level acts on the photovoltaic panel body, the contact wheel can be switched from the holding position to the release position; An energy storage structure, connecting the photovoltaic panel body, and the energy storage structure can drive the photovoltaic panel body to perform a deflection action; The locking shaft is connected to the energy storage structure. The locking shaft cooperates with the trigger frame and can cause the energy storage structure to act when the abutting wheel switches from the holding position to the release position, so as to drive multiple groups of the photovoltaic panel bodies to switch from a coplanar state to a non-coplanar state.

[0006] As a further solution of the present invention: The elastic support assembly includes a pressing plate slidably arranged along the length direction of the pitching bracket. A sliding groove is arranged on the pressing plate, and the sliding groove is slidably connected with a sliding block arranged on the pitching bracket; A connecting rod is also slidably installed in the sliding groove. A first cylindrical spring is sleeved on the connecting rod. One end of the first cylindrical spring is connected to the inner wall of the sliding groove, and the other end is connected to the sliding block.

[0007] As a further solution of the present invention: A limiting groove is arranged at one end of the pressing plate away from the sliding groove. A set of release grooves are arranged on each side of the limiting groove. The limiting groove forms the holding position, and the two release grooves form two release positions; The limiting groove and the release groove are connected by two inclined surfaces, and a protrusion protruding away from the sliding groove is formed at the connection of the two inclined surfaces.

[0008] As a further solution of the present invention: The energy storage structure includes an extension rod connected to the rotating shaft of the photovoltaic panel body. A connecting shaft is arranged at one end of the extension rod away from the rotating shaft of the photovoltaic panel body; The energy storage structure further includes a release kit connected to the connecting frame. A side moving plate is connected to the release kit. Connecting grooves for rolling connection with the connecting shaft are equidistantly arranged on the side moving plate, and the side moving plate is connected to the locking shaft.

[0009] As a further solution of the present invention: The release kit includes a guide rod installed on the connecting frame. The guide rod is slidably connected with a guiding member detachably installed on the side moving plate; The release kit further includes a second cylindrical spring sleeved on the guide rod. One end of the second cylindrical spring is connected to the connecting frame, and the other end is connected to the side moving plate.

[0010] As a further solution of the present invention: A retention groove is arranged on one side of the guiding member away from the side moving plate. The retention groove is in abutting fit with a stop shaft arranged on the guide rod.

[0011] As a further solution of the present invention: The trigger frame extends to the inner side of the side moving plate and is in abutting fit with the locking shaft; An arc portion is provided at one end of the trigger frame away from the pitching bracket. A protruding stop portion is provided on the side of the arc portion facing the side moving plate. When the abutting wheel is switched into the release groove, the locking shaft can be separated from the stop portion.

[0012] As a further solution of the present invention: An adjusting rod is rotatably installed on the support frame. A plurality of through holes are equidistantly arranged along the length direction of the adjusting rod. The connecting shaft installed on the pitching bracket is adapted to the through holes. When the connecting shaft is placed in different through holes, the pitching angle of the pitching bracket can be changed.

[0013] An assembling method of an anti-wind and anti-seismic self-balancing photovoltaic bracket as described above includes the following steps: Step 1: Place the support frame on the concrete foundation and tighten it with bolts. The bolt models are M6, M8 or M10. Step 2: Install the photovoltaic panel body and the energy storage structure on the connecting frame, and then connect the connecting frame to the pitching bracket. Step 3: Install the elastic support assembly on the pitching bracket. By pressing the elastic support structure, the abutting wheel is made to enter the limit groove. Step 4: Adjust the pitching angle of the pitching bracket. The pitching angle is controlled within 30° to 60°, and then the assembly is completed.

[0014] Compared with the prior art, the beneficial effects of the present invention are: First, when the external wind force level is less than the preset level, on the one hand, it can make the photovoltaic panel body deflect at a small angle to buffer the force of the wind acting on the photovoltaic panel body, so as to reduce the forces borne by the support frame, the rotating shafts of the support frame and the pitching bracket, and the rotating shafts of the connecting frame and the pitching bracket. On the other hand, it can keep the photovoltaic panel body within a certain angle range. And because this angle range is very small, the photovoltaic panel body can still have a good power generation effect. Secondly, when the external wind force level is greater than the preset level, the energy storage structure is used to make the photovoltaic panel body deflect until the photovoltaic panel body can deflect to a horizontal state. At this time, the windward area of the photovoltaic panel body is the smallest, so that even if the external wind force level is greater than the preset wind force level, the wind forces on the photovoltaic panel body, the connecting frame, the pitching bracket and the support frame are very small, and the structural stability of the support frame, the rotating shafts of the support frame and the pitching bracket, and the rotating shafts of the connecting frame and the pitching bracket is ensured. By providing the guiding member, the hysteresis groove and the stop shaft, by adjusting the position of the guiding member, the side moving plate can move a certain distance relative to the guiding rod and then stop moving, so that the deflection angle of the photovoltaic panel body can be adjusted, so as to ensure that the photovoltaic panel body can be deflected to a horizontal state by adjusting the position of the guiding member under the condition that the initial angles of the pitching bracket and the connecting frame are different.

Detailed Description of the Invention

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, which can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0028] Please refer to Figures 1 to 10 , in the embodiments of the present invention, a wind and earthquake resistant self-balancing photovoltaic bracket includes: a support frame 1, a connecting frame 12, an elastic support assembly, an energy storage structure, and a locking shaft 1702.

[0029] A pitching bracket 3 with an adjustable pitching angle is provided on the support frame 1, and a trigger frame 21 is connected to the pitching bracket 3. Specifically, an adjusting rod 2 is rotatably installed on the support frame 1, and a plurality of through holes are equidistantly arranged along the length direction of the adjusting rod 2. A coupling shaft 301 installed on the pitching bracket 3 is adapted to the through holes; When the coupling shaft 301 is placed in different through holes, the pitching angle of the pitching bracket 3 can be changed. When the coupling shaft 301 is inserted into different through holes, bolts are also required to connect the coupling shaft 301 and the adjusting rod 2 to prevent loosening between the two, resulting in an unstable angle of the photovoltaic panel body 14 and affecting its power generation efficiency.

[0030] In the initial state, the pitching bracket 3 maintains a state parallel to the photovoltaic panel body 14. At this time, the pitching angles of the pitching bracket 3 and the photovoltaic panel body 14 can be adjusted according to the area where the installation position is located, so that the photovoltaic panel body 14 can obtain the best power generation effect. Specifically, by inserting the coupling shaft 301 into different through holes, the pitching angle of the pitching bracket 3 can be changed. Among them, the support frame 1, the pitching bracket 3, and the adjusting rod 2 can form a triangular structure. By using the stability of the triangle, the pitching bracket 3 and the photovoltaic panel body 14 can have higher stability at a predetermined pitching angle.

[0031] It should be noted that for the angle adjustment of the pitching bracket 3, the technical means adopted can not only be the above-mentioned solution, but also other methods, such as using an electric drive method (electric telescopic rod, air cylinder or hydraulic cylinder). One end of these electric drive methods is rotatably connected to the support frame 1, and the other end is rotatably connected to the pitching bracket 3.

[0032] Please refer to Figures 6 to 7 , the connecting frame 12 is rotatably installed on the pitching bracket 3. A plurality of groups of parallel photovoltaic panel bodies 14 are rotatably installed on the connecting frame 12, and a contact wheel 13 is rotatably installed on the side of the connecting frame 12; The elastic support assembly is connected to the pitching bracket 3. A holding position and two release positions are formed on the elastic support assembly. When wind force exceeding a predetermined level acts on the photovoltaic panel body 14, the contact wheel 13 can be switched from the holding position to the release position.

[0033] In this embodiment, the contact wheel 13 has two position states. One is the state of being in the holding position. At this time, the connecting frame 12 is in a state parallel to the pitching bracket 3, so that the photovoltaic panel body 14 has an angle more conducive to its power generation. The other is the state of being in the release position. At this time, the external force acting on the photovoltaic panel body 14 is greater than the maximum force that the photovoltaic bracket is set to bear. And in this state, the trigger frame 21 has the ability to trigger the energy storage assembly to act, so that a plurality of groups of photovoltaic panel bodies 14 are switched to a horizontal state to reduce the windward area and avoid damage to the support frame 1, the rotating shafts of the support frame 1 and the pitching bracket 3, and the rotating shafts of the connecting frame 12 and the pitching bracket 3 due to excessive force when the wind force acts on the photovoltaic panel body 14.

[0034] The elastic support assembly includes a pressure application plate 6 slidably arranged along the length direction of the pitching bracket 3. A sliding groove 601 is arranged on the pressure application plate 6, and the sliding groove 601 is slidably connected with a sliding block 4 arranged on the pitching bracket 3. Further, a fitting groove 602 is also arranged on the pressure application plate 6, and the fitting groove 602 is in rolling connection with a guiding groove wheel 5 rotatably installed on the pitching bracket 3 to improve the connection stability between the pressure application plate 6 and the pitching bracket 3 and ensure that when the pressure application plate 6 moves, it can move stably along the length direction of the pitching bracket 3; A connecting rod 7 is also slidably installed in the sliding groove 601. A first cylindrical spring 8 is sleeved on the connecting rod 7. One end of the first cylindrical spring 8 is connected to the inner wall of the sliding groove 601, and the other end is connected to the sliding block 4; One end of the pressing plate 6 away from the sliding groove 601 is provided with a limiting groove 9, and a set of release grooves 10 are arranged on each side of the limiting groove 9. The limiting groove 9 forms the holding position, and the two sets of release grooves 10 form two release positions. Among them, the limiting groove 9 and the release groove 10 are connected by two inclined surfaces 11, and a protrusion protruding away from the sliding groove 601 is formed at the connection of the two inclined surfaces 11.

[0035] In the initial state, the first cylindrical spring 8 is in a compressed state. When there is no wind outside, the first cylindrical spring 8 can drive the pressing plate 6 to move towards the abutting wheel 13. At this time, the abutting wheel 13 can be restricted in the limiting groove 9, so as to ensure the parallel state between the connecting frame 12, the photovoltaic panel body 14 and the pitching bracket 3, and enable the photovoltaic panel body 14 to have a better and more stable angle to maintain continuous and efficient power generation of the photovoltaic panel body 14.

[0036] When the external wind force level is less than the predetermined wind force level, the wind force can act on the connecting frame 12 through the photovoltaic panel body 14. At this time, the connecting frame 12 will generate a torque and deflect along its rotation center. During this process, the abutting wheel 13 will perform a circular motion, so that the abutting wheel 13 can disengage from the limiting groove 9 and move along the inclined surface 11 connected to the limiting groove 9 towards the protrusion. At this time, since the radius of the circular motion of the abutting wheel 13 is constant, the pressing plate 6 has a tendency to be squeezed towards the first cylindrical spring 8, so that the first cylindrical spring 8 can be further compressed. At the same time, the first cylindrical spring 8 enables the abutting wheel 13 to move in the reverse direction and reset to the limiting groove 9 by providing a reverse acting force. That is, when the external wind force is lower than the wind force of the predetermined level, the abutting wheel 13 has a certain effect of being corrected, so that the connecting frame 12 tends to be parallel to the pitching bracket 3. On the one hand, this can enable the photovoltaic panel body 14 to deflect at a small angle to buffer the acting force of the wind on the photovoltaic panel body 14, so as to reduce the acting forces borne by the rotating shafts of the support frame 1, the support frame 1 and the pitching bracket 3, and the rotating shafts of the connecting frame 12 and the pitching bracket 3. On the other hand, it can enable the photovoltaic panel body 14 to be maintained within a certain angle range, and because this angle range is very small, the photovoltaic panel body 14 can still have a good power generation effect.

[0037] When the external wind force level is greater than the preset wind force level, similarly, the abutting wheel 13 will also move along the inclined surface 11 connected to the limiting groove 9. At this time, the abutting wheel 13 will move past the protruding part. Subsequently, when the first cylindrical spring 8 releases its elastic potential energy, it can cause the abutting wheel 13 to move along the inclined surface 11 connected to the release groove 10 into the release groove 10. During this process, the trigger frame 21 can release the energy storage structure, and the energy storage structure is used to deflect the photovoltaic panel body 14 until the photovoltaic panel body 14 can be deflected to a horizontal state. At this time, the windward area of the photovoltaic panel body 14 is the smallest, so that even if the external wind force level is greater than the preset wind force level, the wind force acting on the photovoltaic panel body 14, the connecting frame 12, the pitching bracket 3 and the support frame 1 is very small, and it is ensured that when the external wind force level is greater than the preset wind force level, the support frame 1, the rotating shaft between the support frame 1 and the pitching bracket 3, and the rotating shaft between the connecting frame 12 and the pitching bracket 3 will not be damaged.

[0038] Please refer to Figures 8 to 10 , the energy storage structure is connected to the photovoltaic panel body 14, and the energy storage structure can drive the photovoltaic panel body 14 to perform a deflection action; The energy storage structure includes an extension rod 15 connected to the rotating shaft of the photovoltaic panel body 14, and a connecting shaft 16 is provided at one end of the extension rod 15 away from the rotating shaft of the photovoltaic panel body 14; The energy storage structure further includes a release kit connected to the connecting frame 12. A side moving plate 17 is connected to the release kit. Connecting grooves 1701 that are in rolling connection with the connecting shaft 16 are equidistantly arranged on the side moving plate 17, and the side moving plate 17 is connected to the locking shaft 1702, wherein multiple groups of connecting grooves 1701 are arranged in parallel; The release kit includes a guide rod 19 installed on the connecting frame 12, and the guide rod 19 is slidably connected to a guide member 18 detachably installed on the side moving plate 17; The release kit further includes a second cylindrical spring 20 sleeved on the guide rod 19. One end of the second cylindrical spring 20 is connected to the connecting frame 12, and the other end is connected to the side moving plate 17.

[0039] In the initial state, the side movable plate 17 is in a locked state. At this time, the cooperation between the connecting groove 1701 and the connecting shaft 16 can make multiple groups of photovoltaic panel bodies 14 coplanar. In this state, when the pitch angle of the connecting frame 12 is appropriate, it can ensure that each photovoltaic panel body 14 has the best power generation effect. When the external wind force level is greater than the preset wind force level, the abutment wheel 13 can move toward the release groove 10, that is, the connecting frame 12 can be deflected relative to the pitch bracket 3. At this time, the trigger frame 21 will also follow the pitch bracket 3 to deflect relative to the connecting frame 12, and the side movable plate 17 can be unlocked. After the side movable plate 17 is unlocked, the second columnar spring 20 will release the elastic potential energy and drive the side movable plate 17 to move along the length direction of the guide rod 19. At this time, the connecting groove 1701 cooperates with the connecting shaft 16 to drive the photovoltaic panel body 14 to deflect to the horizontal, thereby reducing the windward area of ​​the photovoltaic panel body 14 under this wind condition.

[0040] Furthermore, since the multiple groups of connection grooves 1701 are arranged in parallel, when the side moving plate 17 moves, the multiple groups of photovoltaic panel bodies 14 can be deflected synchronously, and while maintaining parallelism, the windward area generated by the multiple groups of photovoltaic panel bodies 14 can be reduced.

[0041] Based on the above arrangement, when the external wind force level is greater than the preset wind force level, the side movable plate 17 can be unlocked, driving multiple groups of photovoltaic panel bodies 14 to move, thereby reducing the windward area of ​​the photovoltaic panel bodies 14, and further reducing the force borne by the support frame 1, the rotation axis of the support frame 1 and the pitch bracket 3, and the rotation axis of the connecting frame 12 and the pitch bracket 3 when the wind acts on the photovoltaic panel body 14.

[0042] A retardation groove 1801 is provided on a side of the guide member 18 away from the side movable plate 17 , and the retardation groove 1801 is abutted and adapted with a stop shaft 1901 provided on the guide rod 19 .

[0043] In the initial state, the stop shaft 1901 is in the hysteresis groove 1801 and does not abut against the hysteresis groove 1801. When the side movable plate 17 is driven by the second cylindrical spring 20 to move, the stop shaft 1901 will move relative to the side wall of the hysteresis groove 1801 until the stop shaft 1901 abuts against the side wall of the hysteresis groove 1801, so that the photovoltaic panel body 14 can be deflected to a horizontal state, thereby improving the stability of the photovoltaic panel body 14 after being deflected to a horizontal state.

[0044] It should also be noted that when the photovoltaic panel body 14 deflects to the horizontal state, it can be understood that the levelness of the photovoltaic panel body 14 is close to the horizontal state, rather than the completely horizontal state. The main reason is that when the abutting wheels 13 are in the two release slots 10, the angle of the connecting frame 12 itself will also change. Although this angle change is extremely small, it will cause a certain angle between the photovoltaic panel body 14 and the horizontal plane when it deflects to the final state. Of course, this angle is very small, so that the photovoltaic panel body 14 is nearly in the horizontal state after the angle is switched, so as to reduce its windward area.

[0045] Furthermore, since the initial angles of the pitching bracket 3 and the connecting frame 12 can be adjusted, when the pitching bracket 3 and the connecting frame 12 are in different angles, the angles that the photovoltaic panel body 14 needs to rotate to deflect to the horizontal state are different. For example: when the pitching angles of the pitching bracket 3 and the connecting frame 12 are 30°, the photovoltaic panel body 14 needs to deflect 30° when deflecting to the horizontal state, and when the pitching angles of the pitching bracket 3 and the connecting frame 12 are 60°, the photovoltaic panel body 14 needs to deflect 60° when deflecting to the horizontal state. In this application, the guiding member 18 is detachably installed on the side moving plate 17. At this time, by adjusting the position of the guiding member 18, the side moving plate 17 can move a certain distance relative to the guiding rod 19 and then stop moving, so as to realize the adjustment of the deflection angle of the photovoltaic panel body 14, so as to ensure that when the initial angles of the pitching bracket 3 and the connecting frame 12 are different, the photovoltaic panel body 14 can be in the horizontal state after deflection by adjusting the position of the guiding member 18.

[0046] Please refer to Figure 10 , the locking shaft 1702 is connected to the energy storage structure, and the locking shaft 1702 cooperates with the trigger frame 21, and can make the energy storage structure act when the abutting wheel 13 switches from the holding position to the release position, so as to drive multiple groups of the photovoltaic panel bodies 14 to switch from the coplanar state to the non-coplanar state; The trigger frame 21 extends to the inner side of the side moving plate 17 and abuts and adapts to the locking shaft 1702; One end of the trigger frame 21 away from the pitching bracket 3 is provided with an arc portion 2101, and a protruding stop portion 22 is provided on the side of the arc portion 2101 facing the side moving plate 17. When the abutting wheel 13 switches to the release slot 10, the locking shaft 1702 can be separated from the stop portion 22. Among them, the stop portion 22 is also arc-shaped, and the center of the stop portion 22 is concentric with the rotation center of the connecting frame 12.

[0047] In the initial state, the locking shaft 1702 is in a state of abutting against the middle part of the stop portion 22. When the abutting wheel 13 moves along the limiting groove 9 and the inclined surfaces 11 on both sides thereof and has not moved past the protruding portion, the locking shaft 1702 can slide relative to the stop portion 22, but the two will still be in an abutting state. In this state, it can be understood that the external wind force level is less than the predetermined wind force level. The connecting frame 12 buffers the wind force through deflection, but the position of the side moving plate 17 relative to the connecting frame 12 will not change, and it can ensure that multiple groups of photovoltaic panel bodies 14 remain coplanar, so that the photovoltaic panel bodies 14 can have a more stable power generation effect.

[0048] When the abutting wheel 13 moves past the protruding portion, the stop portion 22 will be separated from the locking shaft 1702. At this time, the side moving plate 17 can be released, thereby driving the photovoltaic panel body 14 to deflect to a horizontal state to reduce the windward area of the photovoltaic panel body 14.

[0049] As an embodiment of the present invention, an assembling method of the wind-resistant and shock-absorbing self-balancing photovoltaic support as described above is also proposed, including the following steps: Step 1: Place the support frame 1 on the concrete foundation and tighten it with bolts. The bolt models are M6, M8 or M10; Step 2: Install the photovoltaic panel body 14 and the energy storage structure on the connecting frame 12, and then connect the connecting frame 12 with the pitching support 3; Step 3: Install the elastic support assembly on the pitching support 3. By pressing the elastic support structure, the abutting wheel 13 is made to enter the limiting groove 9; Step 4: Adjust the pitching angle of the pitching support 3, and the pitching angle is controlled within 30° to 60°, and then the assembly is completed.
