Description

Technical Field

[0001] This invention relates to the field of windproof support technology, specifically to a windproof device for photovoltaic equipment. Background Technology

[0002] Photovoltaic panels, also known as solar photovoltaic panels, are the core components of photovoltaic power generation systems. Their core function is to convert solar energy into electrical energy through the photovoltaic effect. A photovoltaic power station is a photovoltaic power generation system that uses solar energy to directly convert light energy into electrical energy through photovoltaic modules and then connects to the public power grid to transmit electricity. It is a green power project that is currently strongly encouraged by the country. In photovoltaic power stations in remote areas, in order to receive high-quality sunlight over a large area and save ground space, and to prevent equipment from covering roads or grasslands, photovoltaic panels and other equipment are often directly fixed at high places by brackets.

[0003] However, due to factors such as the angle of sunlight, photovoltaic panels are often installed at an angle, which significantly obstructs horizontal airflow, reducing wind speed at that height. Meanwhile, the wind speed above the panels is faster, creating a low-pressure area above the panels. This results in the photovoltaic equipment being subjected to an upward thrust, which can easily cause the support structure to break and the photovoltaic panels to be blown away, causing equipment damage or even injuring pedestrians, threatening life and property safety. Furthermore, the support structure has poor wind resistance, affecting the power generation stability and safety of the photovoltaic power station. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a windproof device for photovoltaic equipment, which has a concave shell-shaped windproof platform set at high altitude, and the photovoltaic equipment is set in the concave pit of the windproof platform. The windproof platform shape guides the airflow and transfers the low pressure area to the lower part, thereby improving the windproof and wind-resistant capabilities of the photovoltaic equipment.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A windproof device for photovoltaic equipment includes a support frame, which has a hollow frame structure and multiple such frames are evenly arranged along the circumference, with their bottoms respectively connected and fixed to the ground. The top of the support is horizontally equipped with a steering adjustment module, and the steering adjustment module is equipped with an angle flipping module. The angle flipping module is equipped with a windproof platform, and photovoltaic equipment is installed on the windproof platform. The windproof platform is a concave shell structure with a downward-facing top and an imperfectly spherical bottom. It includes a platform frame with a wind-guiding skin on the platform frame. The photovoltaic equipment is horizontally installed on the windproof platform along the top surface of the wind-guiding skin. The windproof platform can be flipped up and down by an angle-flipping module and rotated horizontally by a steering adjustment module.

[0006] Furthermore, the tilting module includes a directional rotating ring, which is horizontally positioned directly below the windproof platform. A tilting limiting structure and a lateral support structure are provided between the top of the ring and the platform frame. The tilting limiting structure is positioned along the front-to-back direction, and a pair of lateral support structures are mirrored on the left and right sides of the tilting limiting structure. A tilting adjustment component is provided between the tilting limiting structure and the platform frame, and the platform frame tilts back and forth along the tilting limiting structure via the tilting adjustment component.

[0007] Furthermore, the deflection limiting structure includes a limiting arc rail fixed on the directional rotating ring. The limiting arc rail is an arc-shaped U-shaped groove structure with the opening facing upward and both ends bent upward. Limiting arc plates are respectively provided on the top of the two side plates of the limiting arc rail, and limiting pulleys are respectively rotatably provided on the inner wall. Multiple limiting pulleys are evenly arranged along the limiting arc rail. A vertical plate is erected at the bottom of the platform frame, and an arc-shaped limiting slide plate is provided at the bottom of the vertical plate. The limiting slide plate is slidably arranged in the limiting arc rail, and its top abuts against the limiting arc plate, and its bottom abuts against each limiting pulley.

[0008] Furthermore, the deflection adjustment assembly includes an adjustment box, which is located at the bottom of the limiting arc rail and has a vertical gear rotatably mounted inside. A pair of vertical plates are erected at the bottom of the platform frame, and a deflection rack is erected at the bottom of the platform frame between the two vertical plates. The deflection rack is an arc-shaped incomplete toothed ring structure, and its bottom meshes with the vertical gear.

[0009] Furthermore, a worm gear box is provided on one side of the adjustment box, and a meshing worm wheel and worm are rotatably arranged inside the worm gear box. The worm wheel shaft is connected to the vertical gear shaft, and the worm shaft is connected to the deflection motor drive shaft provided on the limiting arc rail.

[0010] Furthermore, the lateral support structure includes a side arc rail, which is arranged parallel to the limiting arc rail, and is provided with a lateral arc plate on its top. Support pulleys are rotatably provided on the inner wall. A side support plate is vertically provided at the bottom of the platform frame corresponding to the side arc rail, and an arc-shaped support slide plate is provided at the bottom of the side support plate. The support slide plate is slidably arranged in the side arc rail, and its top abuts against the side arc plate and its bottom abuts against each support pulley.

[0011] Furthermore, the upright plate, side support plate, and deflection rack are each provided with multiple ventilation guide holes that run from left to right.

[0012] Furthermore, the steering adjustment module includes a support ring, which is horizontally disposed on the top of each bracket. A directional rotating ring is rotatably disposed on the support ring, and its bottom is connected to the top surface of a steering gear ring rotatably disposed inside the support ring. A steering gear that meshes with the steering gear ring is rotatably disposed on one side of the support ring.

[0013] The advantages of this invention compared with the prior art are as follows: 1. This invention sets up a concave shell-shaped windproof platform at high altitude, and the photovoltaic equipment is set in the concave pit of the windproof platform. The shape of the windproof platform guides the airflow and transfers the low-pressure area to the lower part, thereby converting the upward thrust that is originally easy to generate into downward pressure, preventing the top equipment from being blown away. In addition, the bottom surface of the windproof platform is spherical, which can disperse the rising airflow through the guidance, improving the wind resistance of the photovoltaic equipment and making it safer to use. 2. This invention can adjust the deflection angle and direction of the windproof platform, improve the direct angle between the photovoltaic panel and sunlight, increase power generation and conversion efficiency, and make it more convenient to use; 3. The windproof platform of this invention is set at a high place, and only a support is set on the ground. It occupies less ground space and has less impact, and causes less damage and impact on the surrounding environment. It is more convenient and environmentally friendly to use.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] A windproof device for photovoltaic equipment, combined with attached Figure 1 Appendix Figure 2 Appendix Figure 3 As shown, the device includes a steering adjustment module 3, which is horizontally positioned. Multiple supports 4 are evenly arranged around the bottom, and an angle-flipping module 2 is positioned at the top. A windproof platform 1 is mounted on the angle-flipping module 2, and a photovoltaic device 5 is installed on the windproof platform 1. The supports 4 have a hollow frame structure to reduce their weight and wind resistance. In the above structure, the windproof platform 1 is flipped up and down by the angle-flipping module 2 and rotated horizontally by the steering adjustment module 3. The photovoltaic device 5 is less affected by airflow through the windproof platform 1, thus improving its wind resistance.

[0029] Combined with appendix Figure 1 Appendix Figure 10 Appendix Figure 11 Appendix Figure 12 As shown, the windproof platform 1 is a concave shell structure with a downward-facing top and an imperfectly spherical bottom surface. It includes a platform frame 11, which is adapted to the shape of the windproof platform 1. A wind-guiding skin 12 is provided on the outside. The wind-guiding skin 12 is made of plastic or foam gel (to reduce its own weight) and has good flame retardancy, corrosion resistance (for long-term exposure) and insulation. Photovoltaic equipment 5, such as photovoltaic panels, is arranged horizontally and installed in the windproof platform 1 along the top surface of the wind-guiding skin 12 via a mounting bracket 51.

[0030] As described above, the windproof platform 1 is horizontally or slightly tilted at a high altitude. When the airflow at the corresponding altitude blows onto the windproof platform 1, it is guided by the air guide skin 12 and deflected to the sides and downwards in area B. This causes the airflow below the windproof platform 1 to converge and accelerate, forming a low-pressure area in area B below the windproof platform 1 (the faster the gas flow, the lower the pressure in this area). Meanwhile, the airflow velocity in area A above the windproof platform 1 is normal (or slightly decreased), forming a high-pressure area. Under the action of air pressure, the lateral airflow exerts downward pressure on the windproof platform 1, improving the windproof capability and stability of the windproof platform 1. Furthermore, the rising airflow below the windproof platform 1, after impacting the bottom of the windproof platform 1, is guided by the air guide skin 12 and deflected outwards, reducing the upward external force on the windproof platform 1 and minimizing the impact of vertical airflow on the windproof platform 1.

[0031] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 7 As shown, the tilting and flipping module 2 includes a directional rotating ring 21, which is horizontally positioned directly below the windproof platform 1. A tilting limiting structure 22 and a lateral support structure 23 are provided between the top of the rotating ring and the platform frame 11. The tilting limiting structure 22 is positioned along the front-back direction, and a pair of lateral support structures 23 are mirrored on the left and right sides of the tilting limiting structure 22. A tilting adjustment component 24 is provided between the tilting limiting structure 22 and the platform frame 11, and the platform frame 11 can be tilted back and forth along the tilting limiting structure 22 via the tilting adjustment component 24.

[0032] Combined with appendix Figure 4 Appendix Figure 5 Appendix Figure 7 As shown, the deflection limiting structure 22 includes a limiting arc rail 222 fixed on the directional rotating ring 21. The limiting arc rail 222 is an arc-shaped U-shaped groove structure with the opening facing upward and both ends bent upward. Limiting arc plates 223 are respectively provided on the top of the two side plates of the limiting arc rail 222, and limiting pulleys 224 are respectively rotatably provided on the inner wall. Multiple limiting pulleys 224 are evenly arranged along the limiting arc rail 222. A vertical plate 221 is erected at the bottom of the platform frame 11, and an arc-shaped limiting slide plate 225 is provided at the bottom of the vertical plate 221. The limiting slide plate 225 is slidably arranged in the limiting arc rail 222, and its top abuts against the limiting arc plate 223, and its bottom abuts against each limiting pulley 224. Multiple ventilation guide holes 25 are provided on the vertical plate 221 (to reduce the wind resistance to the side wind and allow the airflow to converge and accelerate below the windproof platform 1).

[0033] Combined with appendix Figure 4 Appendix Figure 6 Appendix Figure 7As shown, the lateral support structure 23 includes a side arc rail 232, which is parallel to the limiting arc rail 222. The top of the side arc rail 232 is provided with a lateral arc plate 233, and the inner wall is provided with a support pulley 234. The bottom of the platform frame 11 is provided with a side support plate 231 vertically corresponding to the side arc rail 232. The bottom of the side support plate 231 is provided with an arc-shaped support slide plate 235. The support slide plate 235 is slidably disposed in the side arc rail 232, and its top abuts against the side arc plate 233 and its bottom abuts against each support pulley 234. The side support plate 231 is provided with a plurality of ventilation guide holes 25 that run through the left and right sides.

[0034] Combined with appendix Figure 4 Appendix Figure 5 Appendix Figure 8 As shown, the deflection adjustment assembly 24 includes an adjustment box 243, which is located at the bottom of the limiting arc rail 222 and has a vertical gear 241 rotatably mounted inside. A pair of vertical plates 221 are erected at the bottom of the platform frame 11, and a deflection rack 242 is erected at the bottom of the platform frame 11 between the two vertical plates 221. The deflection rack 242 is an arc-shaped incomplete toothed ring structure, and its bottom meshes with the vertical gear 241. A worm gear box 247 is provided on one side of the adjustment box 243. A worm wheel 244 and a worm 245 are rotatably mounted inside the worm gear box 247, and the rotating shaft of the worm wheel 244 is connected to the rotating shaft of the vertical gear 241. The rotating shaft of the worm 245 is connected to the drive shaft of the deflection motor 246 provided on the limiting arc rail 222. The deflection rack 242 is provided with multiple ventilation guide holes 25 that pass through from left to right.

[0035] As described above, the windproof platform 1 is balanced and limited by the deflection limiting structure 22 and the lateral support structure 23. The lateral airflow passes through the bottom of the windproof platform 1 through the ventilation guide holes 25, reducing the obstruction of the lateral wind by the deflection tilting module 2. This allows the airflow to converge and accelerate below the windproof platform 1, forming a low-pressure area. The deflection motor 246 is then started, which drives the vertical gear 241 to rotate through the worm gear 244 and worm 245. The deflection rack 242 drives the windproof platform 1 to tilt and flip slightly up and down, adjusting the illumination angle of the photovoltaic equipment 5 and improving the power generation efficiency of the photovoltaic equipment 5.

[0036] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 9As shown, the steering adjustment module 3 includes a support ring 31, which is horizontally disposed on the top of each bracket 4. A directional rotating ring 21 is rotatably disposed on the support ring 31, and its bottom is connected to the top surface of a steering gear ring 32 rotatably disposed inside the support ring 31. A steering gear 33 that meshes with the steering gear ring 32 is rotatably disposed on one side of the support ring 31. A motor bracket 36 is disposed on one side of the bottom of the support ring 31, and a steering motor 35 is disposed on the motor bracket 36. The rotating shaft of the steering gear 33 is connected to the output shaft of a reduction gearbox 34 disposed at the bottom of the support ring 31, and the drive shaft of the steering motor 35 is connected to the input shaft of the reduction gearbox 34.

[0037] As described above, after the steering motor 35 is started, the steering gear 33 drives the steering ring 32 to rotate, causing the directional rotating ring 21 to rotate on the support ring 31, adjusting the horizontal direction of the windproof platform 1 and the photovoltaic equipment 5, so that the photovoltaic equipment 5 can follow the sun (the rotation angle of the steering adjustment module 3 is less than 180° and the speed is relatively slow), adjusting the illumination angle of the photovoltaic equipment 5, and improving the power generation efficiency of the photovoltaic equipment 5.

[0038] As described above, rainwater drainage pipes are installed at the wind guide skin 12 and other required locations to drain water and prevent rainwater accumulation. In this embodiment, corresponding control devices, power supply systems, and monitoring equipment are provided to control the steering adjustment module 3 and the tilt angle flipping module 2 according to the sunlight. The control devices, power supply systems, monitoring equipment, and related equipment and usage methods are all existing mature technologies in the photovoltaic power generation field.

[0039] In specific implementations of this invention, the contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Working principle of the invention: The windproof platform 1 is flipped up and down by the tilting module 2 and rotated horizontally by the steering adjustment module 3 to adjust the illumination angle of the photovoltaic equipment 5, thereby improving the power generation efficiency of the photovoltaic equipment 5. During the process, the windproof platform 1 is set horizontally or slightly tilted at a high altitude. After the airflow at the corresponding height blows onto the windproof platform 1, it is guided by the wind guide skin 12 and deflected to the sides and downwards to area B. This causes the airflow below the windproof platform 1 to converge and accelerate, forming a low-pressure area in area B below the windproof platform 1 (the faster the gas flow, the lower the pressure in this area). Meanwhile, the airflow velocity in area A above the windproof platform 1 is normal (or slightly decreased), forming a high-pressure area. Under the action of air pressure, the lateral airflow exerts downward pressure on the windproof platform 1, improving the windproof capability and stability of the windproof platform 1. In addition, the rising airflow below the windproof platform 1, after hitting the bottom of the windproof platform 1, is guided by the wind guide skin 12 and deflected outwards, reducing the upward external force on the windproof platform 1 and reducing the impact of vertical airflow on the windproof platform 1.
