Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a photovoltaic power generation device with high wind resistance and stability. Background Art

[0002] Photovoltaic power generation equipment is to install photovoltaic panels on a fixed bracket with the light-receiving surface facing the sun to receive sunlight and convert solar energy into electrical energy. In order to make the sunlight shine vertically on the photovoltaic panel and increase the conversion efficiency, photovoltaic power generation equipment is mostly placed at an angle.

[0003] Photovoltaic power generation equipment is often installed in the wild, mountainous tidal flats and other places with harsh environments. These places are often hit by strong winds. If it faces the wind from the front, it is fine. If it faces the wind from the back, the photovoltaic panel may be blown to deformation or even fly off. For this reason, a wind-resistant and high-stability photovoltaic power generation device is provided (see patent number: 202221647409.9 for details). The device includes a device body, the device body includes a first fixing frame and a second fixing frame, the height of the first fixing frame is lower than the height of the second fixing frame, and the first fixing frame and the second fixing frame are both fixed to the ground by nails, the first fixing frame and the second fixing frame are embedded with a bottom frame, and the top of the first fixing frame and the second fixing frame is connected to the solar panel body; a wind shield mechanism, the wind shield mechanism includes a wind shield, and the utility model adopts a V-shaped guiding design of the wind shield, which is beneficial to the fact that when the back of the device is exposed to wind, the airflow will not directly act on the back of the solar panel body, thereby reducing lift and reducing the possibility of loosening and falling off.

[0004] However, some existing wind-resistant and high-stability photovoltaic power generation equipment mostly rely on additional wind shields to protect the photovoltaic power generation equipment. However, when the wind is strong, the wind shield may be directly blown down and damage the photovoltaic power generation equipment, posing a safety hazard. Moreover, adding wind shields cannot reduce the windward surface of the photovoltaic power generation equipment, and there is still a possibility of being blown over. In addition, if the photovoltaic power generation equipment is to be protected, the area of ​​the wind shield must be large enough, which also increases the installation cost. Utility Model Content

[0005] The purpose of the utility model is to provide a wind-resistant and highly stable photovoltaic power generation device in order to solve the problems that some current wind-resistant photovoltaic power generation devices have safety hazards when the wind is relatively strong, cannot reduce the wind-exposed area of ​​the photovoltaic power generation devices, and have high installation costs.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a wind-resistant and highly stable photovoltaic power generation device, comprising:

[0007] A first supporting assembly, used to support the photovoltaic power generation equipment;

[0008] A second supporting assembly, located on one side of the first supporting assembly;

[0009] A photovoltaic panel, located on top of the first supporting assembly and used for photovoltaic power generation;

[0010] A lifting assembly located at one end of the photovoltaic panel and the second supporting assembly;

[0011] The first supporting assembly comprises a front column and a rear column, the number of the front columns and the rear columns are both two groups, and damping blocks are provided at the tops of the two groups of front columns and rear columns near one end of the photovoltaic panel, and panel racks are provided at the tops of the two groups of front columns and rear columns near one end of the photovoltaic panel, the second supporting assembly comprises a left diagonal brace and a right diagonal brace, and connecting rods are provided at the tops of adjacent sides of the left diagonal brace and the right diagonal brace, and the lifting assembly comprises a windmill, a pinion shaft is provided at the middle position of one end of the windmill, a pinion is provided on the outside of the pinion shaft and at one end of the windmill, a large gear shaft is rotatably connected to the top of one end of the left diagonal brace, a large gear is provided on the outside of the large gear shaft, the pinion gear is meshed with the large gear, a connecting rod is movably connected to the bottom of one end of the large gear, and a lifting rod is provided at the bottom of one end of the connecting rod.

[0012] As a further solution of the utility model: a rotary hinge is provided at the top of one end of the front column, and the front column is movably connected to the electric panel frame through the rotary hinge.

[0013] As a further solution of the utility model: the top of one end of the connecting rod is rotatably connected to the bottom of one end of the large gear through a rotating shaft, and the bottom of one end of the connecting rod is rotatably connected to the lifting rod.

[0014] As a further solution of the utility model: one end of the lifting rod away from the connecting rod is fixedly connected to the electric board frame.

[0015] As a further solution of the utility model: a slider is provided on one end of the rotating hinge close to the electric panel frame, and a strip slide groove matching the slider is provided on one side of both ends of the electric panel frame close to the front column, and both ends of the electric panel frame close to the front column are slidably connected to the front column through the mutual cooperation of the slider and the strip slide groove.

[0016] As a further solution of the utility model: the photovoltaic panel is installed on the top of the panel frame, and the bottom of the front column and the rear column are both provided with counterweight blocks.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. Fix the device by setting the lifting component. When in use, the rear end of the photovoltaic power generation equipment is affected by wind, and the wind will directly blow the windmill, causing the windmill to rotate counterclockwise, thereby driving the small gear shaft in the center of the windmill to rotate, and then driving the small gear to rotate counterclockwise. Because the large gear is meshed with the small gear, the large gear rotates clockwise, driving the rotating shaft on the large gear to rotate clockwise around the large gear shaft. Because one end of the connecting rod is connected to the rotating shaft and the other end is connected to the lifting rod fixed in the slot, the connecting rod will move clockwise with the lifting rod as the center while moving upward, and then pull the lifting rod along the slide groove of the rear column on the first supporting assembly to lift the front end of the photovoltaic panel. When the height is lifted to the highest, it is blocked by the damping block on the first supporting assembly and the gear stops rotating. At this time, the photovoltaic panel is roughly parallel to the ground, reducing the wind-exposed area.

[0019] 2. Through the setting of the first supporting component, it was found that if the front end of the photovoltaic panel is simply lifted during use, the photovoltaic panel will break. Therefore, there is also a corresponding strip slide groove at the connection between the panel frame and the front column of the first supporting component, so that when the front end of the photovoltaic panel moves upward, the whole panel moves backward horizontally, eliminating the safety hazard. Moreover, counterweight blocks are provided at the bottom of the front column and the rear column to make the photovoltaic power generation equipment more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The working principle of the utility model is:

[0038] The device is fixed, the first support assembly 2 is installed, and then the second support assembly 3 is installed. The lifting assembly 4 is fixed on the second support assembly 3 through the small gear shaft 402 and the large gear shaft 403 of the lifting assembly 4. The first support assembly 2, the second support assembly 3 and the lifting assembly 4 are connected together through the lifting rod 407. Finally, the photovoltaic panel 1 is fixed on the first support assembly 2 to complete the installation operation. When in use, the rear end of the photovoltaic power generation equipment is affected by wind, and the wind will directly blow the windmill 401, causing the windmill 401 to rotate counterclockwise, thereby driving the small gear shaft 402 in the center of the windmill 401 to rotate, and then driving the small gear 404 to rotate counterclockwise. Because the large gear 405 is meshed with the small gear 404, the large gear 405 rotates clockwise, driving the rotating shaft 408 on the large gear 405 to rotate clockwise around the large gear shaft 403. Because one end of the connecting rod 406 is connected to the rotating shaft 408 The connecting rod 406 is connected to the front column 202, and the other end is connected to the lifting rod 407 fixed in the slot, so the connecting rod 406 will move clockwise with the lifting rod 407 as the center while moving upward, and then pull the lifting rod 407 along the slide groove of the rear column 203 on the first support assembly 2 to lift the front end of the photovoltaic panel 1. When the height is raised to the highest, it is blocked by the damping block 205 on the first support assembly 2, and the gear stops rotating. At this time, the photovoltaic panel 1 is roughly parallel to the ground, reducing the wind-exposed area. In addition, during use, if the front end of the photovoltaic panel 1 is simply lifted, it will cause the photovoltaic panel 1 to break. Therefore, there is also a corresponding strip slide groove at the connection between the panel frame 204 of the first support assembly 2 and the front column 202, so that when the front end of the photovoltaic panel 1 moves upward, the whole moves backward horizontally, eliminating the safety hazard. Moreover, counterweight blocks are provided at the bottom of the front column 202 and the rear column 203 to make the photovoltaic power generation equipment more stable.
