Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, specifically a wind-resistant and stable solar panel support device. Background Technology

[0002] Solar panel support devices are key supporting structures used to fix and support solar panels. Their core function is to ensure that solar panels can be stably installed in different scenarios such as rooftops, ground, and water surfaces. They are usually composed of metal brackets (such as aluminum alloys and galvanized steel), connectors, and fasteners. They need to have characteristics such as wind resistance, earthquake resistance, and corrosion resistance to adapt to long-term outdoor use. They are an important component of solar power generation systems to ensure safety and power generation performance.

[0003] Chinese patent CN119743084A discloses a wind-resistant device for photovoltaic panels, including a base plate, multiple photovoltaic panel bodies, and an adjustment mechanism. Multiple rotating plates are rotatably connected to the top of the base plate via a rotating shaft. A sliding sleeve is fixedly connected to the top of each rotating plate, and a sliding support plate is slidably inserted into the sliding sleeve. Both sides of the sliding support plate have arc-shaped grooves, and a guide shaft is fixedly connected between the inner walls of the two ends of the arc-shaped grooves. Springs are sleeved on both ends of the guide shafts, with one end of each spring fixedly connected to the inner wall of one end of the arc-shaped groove. This invention, by pushing the sliding support plate within the sliding sleeve under wind pressure, causes the fixed sliding sleeve to move along the guide shaft, thereby causing the springs to contract. This reduces the impact of wind on the photovoltaic panel body. Simultaneously, a damper further buffers the photovoltaic panel body, preventing damage.

[0004] As shown in the aforementioned patent, existing technologies for wind resistance of photovoltaic panels generally utilize the elasticity of springs to provide auxiliary support. When the wind blows, the photovoltaic panel is compressed by the springs, causing it to rotate horizontally, thereby reducing the wind force on the photovoltaic panel. However, due to the large area of ​​the photovoltaic panel, it takes a certain amount of time for the panel to rotate, and it may still be damaged when subjected to sudden strong gusts of wind.

[0005] Therefore, it is necessary to provide a wind-resistant and stable solar panel support device to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a wind-resistant and stable solar panel support device. By setting up a rotatable rotating seat, an elastic buffer component and a connecting seat, it solves the problems of slow rotation response of photovoltaic panels and easy damage under sudden strong gusts in the prior art, and effectively improves the wind protection capability of photovoltaic panels in the initial stage of gusts.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a wind-resistant and stable solar panel support device, comprising a support frame and a plurality of support mechanisms for supporting the support frame, wherein the support mechanism comprises a support leg, a connecting seat, a rotating seat rotatably mounted on the top of the support leg, and an elastic buffer assembly disposed between the rotating seat and the connecting seat, wherein the two ends of the elastic buffer assembly are respectively connected to the rotating seat and the connecting seat, and the top ends of the plurality of connecting seats are fixedly connected to the support frame.

[0008] A further configuration of the present invention is as follows: the elastic buffer assembly includes a support cylinder, a connecting column, a spring, and a piston. The end of the support cylinder away from the connecting seat is fixedly connected to the rotating seat. The piston is slidably installed inside the support cylinder. One end of the connecting column extends into the support cylinder and is fixedly connected to the piston. The other end of the connecting column is fixedly connected to the connecting seat. The side wall of the piston away from the connecting column is elastically connected to the inner side wall of the support cylinder through the spring.

[0009] A further feature of the present invention is that a limiting rod is fixedly installed on the outer wall of the connecting column, the limiting rod penetrates the end wall of the support cylinder, and the limiting rod slides in cooperation with the support cylinder.

[0010] A further feature of the present invention is that the bottom of the rotating base has an installation cavity, and the top of the support leg extends into the installation cavity.

[0011] A further feature of the present invention is that: the top of the support leg is provided with a plurality of sliding grooves, a sliding column is slidably installed in the sliding groove, a ball is embedded in the top of the sliding column, a second spring is fixedly connected to the bottom of the sliding column, the bottom end of the second spring is fixedly connected to the bottom inner wall of the sliding groove, and a plurality of grooves adapted to the ball are provided on the top inner wall of the mounting cavity.

[0012] A further feature of the present invention is that: a cavity is provided inside the connecting column, an elastic bladder is installed in the cavity, a plurality of connecting holes are provided on the piston, the inner cavity of the support cylinder is connected to the inner cavity of the elastic bladder through the connecting holes, and the inner cavities of the support cylinder, the connecting holes and the elastic bladder are filled with oil.

[0013] A further feature of the present invention is that: a through hole one is provided on the side of the connecting column away from the piston, and a through hole two is provided on the connecting seat. A filter screen is provided on the side of the through hole two away from the connecting column, and the through hole two communicates with the cavity through the through hole one.

[0014] A further feature of the present invention is that an oil filling port is provided on the support cylinder, and a cap is provided on the oil filling port.

[0015] A further feature of the present invention is that: a mounting hole is provided on the rotating seat, a mounting cylinder is fixedly installed in the mounting hole, a slider is slidably arranged in the mounting cylinder, a magnetic block is fixedly installed on the slider, the magnetic block is magnetically attracted to the piston, and an adjustment component for adjusting the position of the slider is provided on the mounting cylinder.

When encountering a sudden strong gust, if there is a deviation between the wind direction and the extension direction of the elastic buffer component, the connecting seat, the elastic buffer component, and the rotating seat can rotate together around the axis of the support leg, so that the extension direction of the elastic buffer component quickly aligns with the wind direction. Then, the extension of the elastic buffer component further buffers the wind force, solving the problem of slow rotation response of photovoltaic panels and easy damage under sudden strong gusts in the prior art, and effectively improving the wind resistance protection capability of photovoltaic panels in the initial stage of gusts. Meanwhile, this solution enhances the buffering effect and avoids frequent swaying in light winds by using the magnetic cooperation between the magnetic block and the piston, the damping effect generated by the flow of oil between the support cylinder and the elastic bladder, and the rotational resistance adjustment structure formed by the cooperation between the sliding column and the groove. Compared with the traditional technology that requires multiple buffer components to cope with wind forces in different directions, this invention enables a single elastic buffer component to buffer wind forces in any direction through a rotational adjustment mechanism. While ensuring wind resistance and stability, it reduces the amount of buffer components used, lowers production costs, and reduces overall costs. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Please see Figures 1 to 8In this embodiment of the invention, a wind-resistant and stable solar panel support device includes a support frame 9 and multiple support mechanisms for supporting the support frame 9. The multiple support mechanisms are arranged in a rectangular array, preferably four. Each support mechanism includes a support leg 1, a connecting seat 6, a rotating seat 2 rotatably mounted on the top of the support leg 1, and an elastic buffer assembly disposed between the rotating seat 2 and the connecting seat 6. Both ends of the elastic buffer assembly are connected to the rotating seat 2 and the connecting seat 6, respectively. The tops of the multiple connecting seats 6 are fixedly connected to the support frame 9, specifically by bolts. A base 22 is fixedly mounted at the bottom of the support leg 1, and the base 22 is bolted to a concrete base on the ground. The photovoltaic panel is mounted on the support frame 9. When the wind blows, if the wind direction deviates from the extension direction of the elastic buffer assembly's telescopic end, the connecting seat 6, the elastic buffer assembly, and the rotating seat 2 rotate together around the axis of the support leg 1, causing the extension direction of the elastic buffer assembly's telescopic end to... In the same direction as the wind, the support frame 9 and the photovoltaic panels installed on top of it can move during the rotation of the rotating seat 2. This moderate movement under wind force provides a certain degree of buffering. Furthermore, after the rotating seat 2 has rotated, the elastic buffer component can stretch under the wind force, further enhancing the buffering effect. This allows for rapid response and buffering in strong winds. Traditional designs often use multiple buffer components to buffer wind forces from different directions, but this solution, due to the rotatable design of the rotating seat 2, elastic buffer component, and connecting seat 6, allows the elastic buffer component to buffer wind forces from any direction, resulting in better buffering performance, reducing the number of buffer components and lowering costs. It should be noted that this solution can be used in conjunction with the patented solution cited in the background technology. A buffering mechanism is also provided at the bottom of the photovoltaic panel to allow it to rotate. The buffering design of this solution is mainly suitable for the initial buffering stage of strong gusts; subsequent wind-avoidance design of the rotating photovoltaic panel is still needed to achieve wind resistance.

[0022] This invention achieves rapid response and buffering in the initial stage of strong gusts by setting up a rotatable rotating seat 2, an elastic buffer component, and a connecting seat 6 in a coordinated structure. When encountering a sudden strong gust, if there is a deviation between the wind direction and the extension / retraction direction of the elastic buffer component, the connecting seat 6, the elastic buffer component, and the rotating seat 2 can rotate together around the axis of the support leg 1, so that the extension / retraction direction of the elastic buffer component quickly aligns with the wind direction. Then, the extension of the elastic buffer component further buffers the wind force, solving the problem of slow rotation response of photovoltaic panels and easy damage under sudden strong gusts in the prior art, effectively improving the wind resistance of photovoltaic panels in the initial stage of gusts. Compared with the traditional technology that requires multiple buffer components to cope with wind forces in different directions, this invention uses a rotation adjustment mechanism so that a single elastic buffer component can buffer wind forces in any direction. While ensuring wind resistance stability, it reduces the number of buffer components used, lowers production costs, and achieves the beneficial effect of balancing buffering effect and economy.

[0023] In this embodiment, preferably, the elastic buffer assembly includes a support cylinder 3, a connecting column 5, a spring 7, and a piston 4. The end of the support cylinder 3 away from the connecting seat 6 is fixedly connected to the rotating seat 2. The piston 4 is slidably installed inside the support cylinder 3. One end of the connecting column 5 extends into the support cylinder 3 and is fixedly connected to the piston 4. The other end of the connecting column 5 is fixedly connected to the connecting seat 6. The side wall of the piston 4 away from the connecting column 5 is elastically connected to the inner side wall of the support cylinder 3 through the spring 7. The connecting column 5 is the telescopic end of the elastic buffer assembly. When there is no wind, the spring 7 is in its natural state. Under the action of wind, the support frame 9 drives the connecting seat 6 to move, thereby driving the connecting column 5 to move away from the rotating seat 2, thus stretching the spring 7. The resistance of the spring 7 when it is stretched plays a buffering role.

[0024] In this embodiment, preferably, a limiting rod 8 is fixedly installed on the outer wall of the connecting column 5. The limiting rod 8 penetrates the end wall of the support cylinder 3 and slides with the support cylinder 3. By setting the limiting rod 8, the connecting column 5 can be limited, so that the connecting column 5 can only slide relative to the support cylinder 3 and cannot rotate relative to the support cylinder 3. A telescopic sealing sleeve 10 is sleeved on the connecting column 5. One end of the telescopic sealing sleeve 10 is fixedly connected to the connecting seat 6, and the other end of the telescopic sealing sleeve 10 is fixedly connected to the end wall of the support cylinder 3. The telescopic sealing sleeve 10 is made of elastic rubber and has a corrugated structure, so that the telescopic sealing sleeve 10 can extend and retract. The telescopic sealing sleeve 10 can protect the connecting column 5 and prevent external dust from adhering to the outer wall of the connecting column 5.

[0025] In this embodiment, preferably, the bottom of the rotating seat 2 has a mounting cavity 203, and the top of the support leg 1 extends into the mounting cavity 203; a bearing 11 is sleeved on the top of the support leg 1, and the bearing 11 is disposed in the mounting cavity 203. The support leg 1 is rotatably connected to the rotating seat 2 through the bearing 11 to reduce friction; the top of the support leg 1 has multiple sliding grooves 101, and a sliding column 12 is slidably installed in the sliding groove 101. A ball bearing 13 is embedded in the top of the sliding column 12, and a spring 14 is fixedly connected to the bottom of the sliding column 12. The bottom end of the second spring 14 is fixedly connected to the bottom inner wall of the slide groove 101. The top inner wall of the mounting cavity 203 is provided with a plurality of grooves 201 that are adapted to the ball 13. When the rotating seat 2 rotates, the ball 13 intermittently extends into the groove 201. When the ball 13 extends into the groove 201, it can increase the resistance of the rotation of the rotating seat 2, so that the rotating seat 2 will not rotate when the external wind force is small, so as to prevent the rotating seat 2 from rotating frequently and reducing its service life. In addition, the rotating seat 2 has a certain resistance when rotating, which can play a certain buffering role in windy weather.

[0026] In this embodiment, preferably, the connecting column 5 has a cavity 501 inside, and an elastic bladder 15 is installed inside the cavity 501. The piston 4 has multiple connecting holes 401. The inner cavity of the support cylinder 3 is connected to the inner cavity of the elastic bladder 15 through the connecting holes 401. The inner cavities of the support cylinder 3, the connecting holes 401, and the elastic bladder 15 are filled with oil, such as hydraulic oil, methyl silicone oil, or synthetic damping oil. When the piston 4 moves, the oil flows between the support cylinder 3 and the elastic bladder 15 through the connecting holes 401, so that the movement of the piston 4 has a certain damping, which can further improve the buffering effect and effectively prevent the connecting seat 6 from frequently swaying back and forth in light winds. The elastic bladder 15 has a certain elasticity and can expand and contract. The elastic bladder 15 can be made of materials such as nitrile rubber or thermoplastic polyurethane elastomer.

[0027] In this embodiment, preferably, the connecting post 5 has a through hole 502 on the side away from the piston 4, and the connecting seat 6 has a through hole 601. The side of the through hole 601 away from the connecting post 5 is provided with a filter screen, and the through hole 601 is connected to the cavity 501 through the through hole 502. With the through holes 502 and 601, the air in the cavity 501 can be exchanged with the external environment when the elastic bladder 15 expands and contracts, and the filter screen can prevent large particles of impurities from entering the cavity 501.

[0028] In this embodiment, preferably, the support cylinder 3 is provided with a filling port 21, and the filling port 21 is provided with a cap. Oil can be filled into the support cylinder 3 through the filling port 21, and different oils can be replaced through the filling port 21 according to the usage requirements.

[0029] Please see Figure 3 and Figure 9 In this embodiment of the invention, the rotating seat 2 has a mounting hole 202, and a mounting cylinder 16 is fixedly installed in the mounting hole 202. A slider 19 is slidably arranged in the mounting cylinder 16, and a magnetic block 20 is fixedly installed on the slider 19. The magnetic block 20 is magnetically attracted to the piston 4. The middle part of the piston 4 is made of a magnetic material. The mounting cylinder 16 is provided with an adjustment component for adjusting the position of the slider 19. The adjustment component includes a screw 17 and a knob 18. One end of the screw 17 is rotatably connected to the slider 19, and the other end of the screw 17 is fixedly connected to the knob 18. The screw 17 passes through the mounting cylinder 16. The screw 17 is threadedly connected to the side wall of the mounting cylinder 16. The magnetic block 20 can generate a magnetic attraction force on the piston 4, which increases the resistance when the piston 4 drives the spring 7 to stretch, thereby improving the buffering effect. The magnitude of the magnetic attraction force can be adjusted by moving the magnetic block 20. When the weight of the photovoltaic panel installed on the support frame 9 is large, the magnetic block 20 can be adjusted to be closer to the piston 4 to improve the buffering effect and adapt to photovoltaic panels of different specifications. When adjusting the position of the magnetic block 20, the screw 17 is rotated by the knob 18. When the screw 17 rotates, it can drive the slider 19 to move, thereby driving the magnetic block 20 to move, thereby adjusting the position of the magnetic block 20.

[0030] Working principle: When encountering strong winds, if there is a deviation between the wind direction and the extension direction of the elastic buffer component, the connecting seat 6, the elastic buffer component, and the rotating seat 2 will rotate together around the axis of the supporting leg 1 to quickly adjust the extension direction of the elastic buffer component to be consistent with the wind direction. During this process, the support frame 9 and the photovoltaic panel move together to initially buffer the wind impact. After the rotation adjustment is completed, the connecting column 5 in the elastic buffer component will drive the piston 4 to stretch the spring 7 under the action of the wind. The tension resistance of the spring 7 will be used to further buffer the wind force, realizing a rapid response and initial buffering of wind force in any direction. The buffering effect of the elastic buffer assembly is further enhanced by the synergy of multiple structures: when the piston 4 moves, the oil in the inner cavity of the support cylinder 3 and the elastic bladder 15 flows through the connecting hole 401. The oil flow damping prevents the connecting seat 6 from shaking frequently in a light wind and improves the buffering performance. At the same time, the elastic bladder 15 can expand and contract with the flow of oil. The sliding column 12, spring 14 and ball 13 at the bottom of the rotating seat 2 cooperate to prevent the rotating seat 2 from rotating randomly when the external wind force is small, reducing the wear and tear on the device caused by frequent rotation. In strong winds, the ball 13 and the groove 201 provide a certain rotational resistance to assist in buffering. The device can also flexibly adjust the buffering capacity according to the specifications of the photovoltaic panel: the magnetic block 20 inside the mounting cylinder 16 on the rotating seat 2 is magnetically attracted to the piston 4, which can increase the resistance of the piston 4 tension spring 7. By adjusting the component to rotate the knob 18, the screw 17 moves the slider 19, thereby changing the distance between the magnetic block 20 and the piston 4, and adjusting the magnetic attraction force to adapt to photovoltaic panels of different weights, ensuring that a good wind-resistant buffering effect can be maintained in different scenarios.
