Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically a wind-resistant and shock-resistant self-balancing photovoltaic support and its assembly method. Background Technology

[0002] The use of photovoltaic (PV) 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, increasing energy independence, and promoting employment, PV panels provide important support for achieving the Sustainable Development Goals.

[0003] To ensure the power generation efficiency of photovoltaic (PV) panels, they are generally installed in areas without external obstructions, such as rooftops, water surfaces, and plateaus. These areas share a common characteristic: strong natural winds. To improve the power generation efficiency of PV panels, existing PV panel supports have a certain range of angle adjustment capabilities. While this can further improve the power generation efficiency of PV panels, it also creates certain drawbacks. The main issue is that to allow for fine-tuning of the PV panel angle, the PV panel needs to be rotatably connected to the PV panel support, meaning there is a pivot between them. When external wind forces act on the PV panel, the force is transmitted to this pivot. Excessive wind force can easily cause the pivot to deform or even break, affecting the stable operation of the PV panel. Summary of the Invention

[0004] The purpose of this invention is to provide a wind-resistant and earthquake-resistant self-balancing photovoltaic support and its assembly method, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A wind- and earthquake-resistant self-balancing photovoltaic support system includes:

[0007] A support frame, on which a pitch bracket with an adjustable pitch angle is provided, and a trigger frame is connected to the pitch bracket;

[0008] A connecting frame is rotatably mounted on the pitch support, and multiple sets of parallel photovoltaic panel bodies are rotatably mounted on the connecting frame. Abutment wheels are rotatably mounted on the side of the connecting frame.

[0009] An elastic support assembly is connected to the pitch support bracket. The elastic support assembly has a holding position and two sets of release positions. When wind force exceeding a predetermined level acts on the photovoltaic panel body, the abutment wheel can be switched from the holding position to the release position.

[0010] An energy storage structure is connected to the photovoltaic panel body, and the energy storage structure can drive the photovoltaic panel body to perform a deflection action;

[0011] A 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 move when the abutment wheel switches from the holding position to the releasing position, so as to drive multiple sets of photovoltaic panels to switch from a coplanar state to a non-coplanar state.

[0012] As a further aspect of the present invention: the elastic support assembly includes a pressure plate that is slidably disposed along the length direction of the pitch support, the pressure plate being provided with a sliding groove, and the sliding groove being slidably connected to a slider disposed on the pitch support;

[0013] A connecting rod is also slidably installed inside the 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 groove, and the other end is connected to the slider.

[0014] As a further embodiment of the present invention: a limiting groove is provided at the end of the pressure plate away from the slide groove, and a set of release grooves is provided on the side of each limiting groove, the limiting grooves form the holding position, and the two sets of release grooves form two sets of release positions;

[0015] The limiting groove and the release groove are connected by two sets of inclined surfaces, and an outward protrusion is formed at the connection of the two sets of inclined surfaces, which protrudes away from the sliding groove.

[0016] As a further embodiment of the present invention: the energy storage structure includes an extension rod connected to the rotating shaft of the photovoltaic panel body, and a connecting shaft is provided at the end of the extension rod away from the rotating shaft of the photovoltaic panel body;

[0017] The energy storage structure also includes a release kit that connects to the connecting frame. A side moving plate is connected to the release kit. The side moving plate is provided with connecting grooves that are equidistant from each other and are tactilely connected to the connecting shaft. The side moving plate is also connected to the locking shaft.

[0018] As a further embodiment of the present invention: the release kit includes a guide rod mounted on the connecting frame, the guide rod being slidably connected to a guide member detachably mounted on the side moving plate;

[0019] The release kit also includes a second cylindrical spring sleeved on the guide rod, one end of which is connected to the connecting frame and the other end of which is connected to the side moving plate.

[0020] As a further embodiment of the present invention: a hysteresis groove is provided on the side of the guide member away from the side moving plate, and the hysteresis groove is adapted to abut against the stop shaft provided on the guide rod.

[0021] As a further embodiment of the present invention: the trigger frame extends to the inner side of the side moving plate and abuts against and is adapted to the locking shaft;

[0022] The trigger frame has an arc-shaped portion at one end away from the pitch support, and a protruding stop portion is provided on the side of the arc-shaped portion facing the side moving plate. When the abutment wheel is switched into the release groove, the locking shaft can separate from the stop portion.

[0023] As a further embodiment of the present invention: an adjusting rod is rotatably mounted on the support frame, and the adjusting rod has a plurality of through holes equidistantly arranged along its length direction, and the connecting shaft mounted on the pitch support is adapted to the through holes;

[0024] When the connecting shaft is placed in different through holes, the pitch angle of the pitch support can be changed.

[0025] An assembly method for a wind-resistant and earthquake-resistant self-balancing photovoltaic support as described above includes the following steps:

[0026] Step 1: Place the support frame on the concrete foundation and tighten it with bolts of type M6, M8 or M10.

[0027] Step 2: Install the photovoltaic panel body and energy storage structure onto the connecting frame, and then connect the connecting frame to the pitch support;

[0028] Step 3: Install the elastic support assembly onto the pitch bracket, and press the elastic support structure to allow the abutment wheel to enter the limiting groove;

[0029] Step 4: Adjust the pitch angle of the pitch support, controlling it between 30° and 60°, and then complete the assembly.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] First, when the external wind force is lower than the preset level, the photovoltaic panel body can be deflected at a small angle to buffer the force of the wind on the photovoltaic panel body, thereby reducing the force on the pivot points of the support frame, the support frame and the pitch support, and the connecting frame and the pitch support. On the other hand, the photovoltaic panel body can be kept within a certain angle range, and because the angle range is very small, the photovoltaic panel body can still have good power generation effect. Second, when the external wind force is higher than the preset level, the energy storage structure is used to deflect the photovoltaic panel body until the photovoltaic panel body can be deflected to a horizontal state. At this time, the windward area of ​​the photovoltaic panel body is minimized, so that even if the external wind force is higher than the preset wind force level, the wind force on the photovoltaic panel body, the connecting frame, the pitch support and the support frame is very small, thus ensuring the structural stability of the pivot points of the support frame, the support frame and the pitch support, and the connecting frame and the pitch support.

[0032] By using guides, hysteresis grooves, and stop shafts, the position of the guides can be adjusted to allow the side moving plate to move a certain distance relative to the guide rod and then stop moving. This allows for adjustment of the deflection angle of the photovoltaic panel body, ensuring that even with different initial angles of the pitch support and connecting frame, the photovoltaic panel body can be kept horizontal after deflection by adjusting the position of the guides.

[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 1-10 In this embodiment of the invention, a wind-resistant and shock-resistant self-balancing photovoltaic support includes: a support frame 1, a connecting frame 12, an elastic support component, an energy storage structure, and a locking shaft 1702.

[0047] The support frame 1 is provided with a pitch bracket 3 whose pitch angle can be adjusted. A trigger frame 21 is connected to the pitch bracket 3. Specifically, an adjusting rod 2 is rotatably installed on the support frame 1. The adjusting rod 2 has multiple through holes equidistantly arranged along its length direction. The connecting shaft 301 installed on the pitch bracket 3 is adapted to the through holes.

[0048] When the connecting shaft 301 is placed in different through holes, the pitch angle of the pitch support 3 can be changed. When the connecting shaft 301 is inserted into different through holes, bolts are also needed to connect the connecting shaft 301 and the adjusting rod 2 to prevent them from becoming loose, which would cause the angle of the photovoltaic panel body 14 to be unstable and affect its power generation efficiency.

[0049] In the initial state, the pitch support 3 is parallel to the photovoltaic panel body 14. At this time, the pitch angle of the pitch support 3 and the photovoltaic panel body 14 can be adjusted according to the area where the installation location is located so that the photovoltaic panel body 14 can obtain the best power generation effect. Specifically, by inserting the coupling 301 into different through holes, the pitch angle of the pitch support 3 can be changed. In this process, the support frame 1, the pitch support 3, and the adjusting rod 2 can form a triangular structure. Utilizing the stability of the triangle, the pitch support 3 and the photovoltaic panel body 14 can have higher stability at the predetermined pitch angle.

[0050] It should be noted that, for the angle adjustment of the pitch support 3, the technical means can not only adopt the above-mentioned scheme, but also other methods, such as electric drive (electric telescopic rod, 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 pitch support 3.

[0051] Please see Figures 6-7 The connecting frame 12 is rotatably mounted on the pitch support 3, and multiple sets of parallel photovoltaic panel bodies 14 are rotatably mounted on the connecting frame 12. Abutment wheels 13 are rotatably mounted on the side of the connecting frame 12.

[0052] The elastic support assembly is connected to the pitch support 3. The elastic support assembly has a holding position and two sets of release positions. When wind force exceeding a predetermined level acts on the photovoltaic panel body 14, the abutment wheel 13 can switch from the holding position to the release position.

[0053] In this embodiment, the abutment wheel 13 has two position states. The first is the holding position, in which the connecting frame 12 is parallel to the pitch support 3, so that the photovoltaic panel body 14 has an angle more conducive to its power generation. The second is the releasing position, in which the external force acting on the photovoltaic panel body 14 is greater than the maximum force that the photovoltaic support can withstand. In this state, the trigger frame 21 has the ability to trigger the energy storage component to switch multiple sets of photovoltaic panel bodies 14 to a horizontal state, so as to reduce the windward area and avoid damage to the support frame 1, the pivot of the support frame 1 and the pitch support 3, and the pivot of the connecting frame 12 and the pitch support 3 due to excessive force when the wind acts on the photovoltaic panel body 14.

[0054] The elastic support assembly includes a pressure plate 6 that is slidably disposed along the length of the pitch support 3. The pressure plate 6 is provided with a sliding groove 601, which is slidably connected to a slider 4 disposed on the pitch support 3. Furthermore, the pressure plate 6 is also provided with a fitting groove 602, which is rotatably connected to a guide wheel 5 rotatably mounted on the pitch support 3 to improve the connection stability between the pressure plate 6 and the pitch support 3 and ensure that the pressure plate 6 can move stably along the length of the pitch support 3 when it moves.

[0055] A connecting rod 7 is also slidably installed in the slide 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 slide groove 601, and the other end is connected to the slider 4.

[0056] The pressure plate 6 is provided with a limiting groove 9 at one end away from the slide groove 601. Each side of the limiting groove 9 is provided with a set of release grooves 10. The limiting groove 9 forms the holding position, and the two sets of release grooves 10 form two sets of release positions. The limiting groove 9 and the release groove 10 are connected by two sets of inclined surfaces 11. The connection of the two sets of inclined surfaces 11 forms an outward protrusion that protrudes away from the slide groove 601.

[0057] In the initial state, the first columnar spring 8 is compressed. When there is no wind, the first columnar spring 8 can drive the pressure plate 6 to move toward the abutment wheel 13. At this time, the abutment wheel 13 can be restricted in the limiting groove 9, thereby ensuring the parallel state between the connecting frame 12, the photovoltaic panel body 14 and the pitch support 3, so that the photovoltaic panel body 14 can have a better and more stable angle, so as to maintain the photovoltaic panel body 14 can generate electricity continuously and efficiently.

[0058] When the external wind force is less than the predetermined wind force, 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 torque and deflect along its rotation center. During this process, the abutment wheel 13 will make a circular motion, allowing the abutment wheel 13 to disengage from the limiting groove 9 and move towards the outward protrusion along the inclined surface 11 connected to the limiting groove 9. Since the radius of the circular motion of the abutment wheel 13 is constant, the pressure plate 6 has a tendency to be squeezed towards the first columnar spring 8, allowing the first columnar spring 8 to be further compressed. At the same time, the first columnar spring 8 provides a counterforce, allowing the abutment wheel 13 to... The reverse movement and reset to the limiting groove 9 means that when the external wind force is lower than the predetermined level, the abutment wheel 13 has a certain correction effect, making the connecting frame 12 tend to be parallel to the pitch support 3. On the one hand, this can make the photovoltaic panel body 14 deflect at a small angle to buffer the force of the wind on the photovoltaic panel body 14, thereby reducing the force borne by the support frame 1, the pivot of the support frame 1 and the pitch support 3, and the pivot of the connecting frame 12 and the pitch support 3. On the other hand, it can keep the photovoltaic panel body 14 within a certain angle range, and since the angle range is very small, the photovoltaic panel body 14 can still have a good power generation effect.

[0059] When the external wind force level is greater than the preset wind force level, the abutment wheel 13 will move along the inclined surface 11 connected to the limiting groove 9. At this time, the abutment wheel 13 will move past the protrusion. Then, when the first columnar spring 8 releases its elastic potential energy, the abutment wheel 13 can 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 can be 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 on the photovoltaic panel body 14, the connecting frame 12, the pitch support 3 and the support frame 1 is very small. This ensures that the support frame 1, the pivot of the support frame 1 and the pitch support 3 and the pivot of the connecting frame 12 and the pitch support 3 will not be damaged when the external wind force level is greater than the preset wind force level.

[0060] Please see Figures 8-10 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;

[0061] 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.

[0062] The energy storage structure also includes a release kit that connects to the connecting frame 12. A side moving plate 17 is connected to the release kit. The side moving plate 17 is provided with connecting grooves 1701 that are equidistant from each other and are tactilely connected to the connecting shaft 16. The side moving plate 17 is connected to the locking shaft 1702. Multiple sets of connecting grooves 1701 are arranged in parallel.

[0063] The release kit includes a guide rod 19 mounted on the connecting frame 12, the guide rod 19 being slidably connected to a guide 18 detachably mounted on the side moving plate 17;

[0064] The release kit also includes a second cylindrical spring 20 sleeved on the guide rod 19, one end of the second cylindrical spring 20 being connected to the connecting frame 12 and the other end being connected to the side moving plate 17.

[0065] In the initial state, the side-moving plate 17 is locked. At this time, the cooperation between the connecting groove 1701 and the connecting shaft 16 enables multiple photovoltaic panel bodies 14 to be coplanar. In this state, when the pitch angle of the connecting frame 12 is appropriate, the photovoltaic panel body 14 can be guaranteed to have 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 towards the release groove 10, that is, the connecting frame 12 can deflect relative to the pitch support 3. At this time, the trigger frame 21 will also deflect relative to the connecting frame 12 along with the pitch support 3, and the side-moving plate 17 can be unlocked. After the side-moving plate 17 is unlocked, the second columnar spring 20 will release elastic potential energy and drive the side-moving plate 17 to move along the length direction of the guide rod 19. At this time, the cooperation between the connecting groove 1701 and the connecting shaft 16 can drive the photovoltaic panel body 14 to deflect to the horizontal, thereby reducing the windward area of ​​the photovoltaic panel body 14 under the wind force conditions.

[0066] Furthermore, since the multiple sets of connecting slots 1701 are arranged in parallel, when the side moving plate 17 moves, the multiple sets of photovoltaic panel bodies 14 can deflect synchronously, maintaining parallelism while reducing the windward area generated by the multiple sets of photovoltaic panel bodies 14.

[0067] Based on the above settings, when the external wind force level is greater than the preset wind force level, the side-moving plate 17 can be unlocked, driving multiple sets of photovoltaic panel bodies 14 to move, thereby reducing the windward area of ​​the photovoltaic panel body 14, and thus reducing the force borne by the support frame 1, the pivot of the support frame 1 and the pitch support 3, and the pivot of the connecting frame 12 and the pitch support 3 when the wind acts on the photovoltaic panel body 14.

[0068] The guide 18 is provided with a hysteresis groove 1801 on the side away from the side moving plate 17, and the hysteresis groove 1801 abuts and is adapted to the stop shaft 1901 provided on the guide rod 19.

[0069] 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 plate 17 is driven to move by the second columnar spring 20, 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 just deflect to a horizontal state, thereby improving the stability of the photovoltaic panel body 14 after it deflects to a horizontal state.

[0070] It should also be noted that the photovoltaic panel body 14 being deflected to a horizontal state can be understood as the photovoltaic panel body 14 being close to a horizontal state, rather than a completely horizontal state. The main reason is that when the abutment wheel 13 is 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 the photovoltaic panel body 14 to have a certain angle with the horizontal plane when it is deflected to the final state. Of course, this angle is very small, so that the photovoltaic panel body 14 is almost horizontal after the angle is switched, thereby reducing its windward area.

[0071] Furthermore, since the initial angles of the pitch support 3 and the connecting frame 12 are adjustable, the angle of rotation required for the photovoltaic panel body 14 to deflect to a horizontal state varies depending on the pitch support 3 and the connecting frame 12 being at different angles. For example, when the pitch angle of the pitch support 3 and the connecting frame 12 is 30°, the photovoltaic panel body 14 needs to deflect 30° to a horizontal state; when the pitch angle of the pitch support 3 and the connecting frame 12 is 60°, the photovoltaic panel body 14 needs to deflect 60° to a horizontal state. In this application, the guide 18 is detachably mounted on the side moving plate 17. By adjusting the position of the guide 18, the side moving plate 17 can move a certain distance relative to the guide rod 19 and then stop moving, thereby adjusting the deflection angle of the photovoltaic panel body 14. This ensures that, regardless of the initial angles of the pitch support 3 and the connecting frame 12, the photovoltaic panel body 14 can be deflected to a horizontal state by adjusting the position of the guide 18.

[0072] Please see Figure 10 The locking shaft 1702 is connected to the energy storage structure. The locking shaft 1702 cooperates with the trigger frame 21 and can cause the energy storage structure to move when the abutment wheel 13 switches from the holding position to the releasing position, so as to drive multiple sets of photovoltaic panel bodies 14 to switch from a coplanar state to a non-coplanar state.

[0073] The trigger frame 21 extends to the inner side of the side moving plate 17 and is adapted to abut against the locking shaft 1702;

[0074] The trigger frame 21 has an arc-shaped portion 2101 at one end away from the pitch support 3. The arc-shaped portion 2101 has a protruding stop portion 22 on the side facing the side moving plate 17. When the abutment wheel 13 is switched into the release groove 10, the locking shaft 1702 can separate from the stop portion 22. 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.

[0075] In the initial state, the locking shaft 1702 is in contact with the middle of the stop part 22. When the abutting wheel 13 moves with the limiting groove 9 and the inclined surfaces 11 on both sides without moving past the protrusion, the locking shaft 1702 can slide relative to the stop part 22, but the two will still be in contact. In this state, it can be understood that the external wind force is less than the predetermined wind force, and the connecting frame 12 buffers the wind force by deflection. However, the position of the side moving plate 17 relative to the connecting frame 12 will not change, so as to ensure that the multiple photovoltaic panel bodies 14 remain in a coplanar state, so that the photovoltaic panel bodies 14 can have a more stable power generation effect.

[0076] When the abutment wheel 13 moves past the outer protrusion, the stop part 22 will separate 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, so as to reduce the windward area of ​​the photovoltaic panel body 14.

[0077] As an embodiment of the present invention, an assembly method for a wind-resistant and earthquake-resistant self-balancing photovoltaic support as described above is also proposed, comprising the following steps:

[0078] Step 1: Place support frame 1 on the concrete foundation and tighten it with bolts of type M6, M8 or M10.

[0079] Step 2: Install the photovoltaic panel body 14 and the energy storage structure onto the connecting frame 12, and then connect the connecting frame 12 to the pitch support 3;

[0080] Step 3: Install the elastic support assembly onto the pitch bracket 3, and press the elastic support structure to make the abutment wheel 13 enter the limiting groove 9;

[0081] Step 4: Adjust the pitch angle of the pitch support 3, controlling the pitch angle between 30° and 60°, and then complete the assembly.
