Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panels, and in particular relates to a photovoltaic windproof device. Background Art

[0002] With the intensification of the global energy crisis and rising awareness of environmental protection, solar power generation has attracted widespread attention as a clean, renewable energy source. As the core component of a solar power generation system, the stability and durability of photovoltaic panels are crucial to the efficiency of the entire power generation system.

[0003] Existing photovoltaic panel brackets are often designed with a focus on cost control and neglect adaptability to extreme weather conditions. In strong winds, these brackets are prone to deformation, damage, and even causing photovoltaic panels to fall off, which not only affects power generation efficiency but may also cause safety hazards and economic losses. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic windbreak device with good windbreak effect in response to the above-mentioned technical problems.

[0005] In view of this, the utility model provides a photovoltaic wind protection device, including a support frame, any two adjacent support frames are rotatably connected to the upper part with a mounting plate, a driving unit is arranged between the mounting plate and the support frame, and the driving unit can drive the mounting plate to rotate, and several of the above-mentioned mounting plates are connected to the same reinforcement plate at the bottom, and the reinforcement plates are symmetrically arranged on both sides of the mounting plate along the arrangement direction of the support frames, and the reinforcement plates are connected to a pressing assembly, which can connect the photovoltaic panel and the reinforcement plate.

[0006] In the present technical solution, a photovoltaic panel is provided on the mounting plate, and a driving unit is provided between the mounting plate and the support frame. When there is strong wind, the driving unit drives the mounting plate to rotate relative to the support frame so that it is parallel to the wind direction or at a certain angle, which can significantly reduce the area directly subjected to wind force, thereby reducing the structural load caused by wind pressure; by symmetrically arranging reinforcement plates on both sides of the bottom of the mounting plate, several mounting plates are connected in series, and the reinforcement plates are connected with a pressure component, which can connect the photovoltaic panel and the reinforcement plate, thereby improving the safety and reliability of the overall structure.

[0007] In the above technical solution, further, the pressure component includes a first pressure member and a second pressure member. The first pressure member is arranged on one side of the end photovoltaic panel, and the first pressure member can buckle the connection between the photovoltaic panel and the reinforcement plate. The second pressure member is arranged between any two photovoltaic panels, and the second pressure member can press the connection between the photovoltaic panels on both sides and the reinforcement plate.

[0008] In the above technical solution, further, the reinforcement plate is a C-shaped channel steel with an opening facing upward.

[0009] In the above technical solution, further, the first pressure member includes a "Z"-shaped first pressure plate, one end of the first pressure plate is against the top of the photovoltaic panel, and the other end is against the top of the reinforcement plate. A fastening bolt is passed through one side of the first pressure plate and the reinforcement plate, and the fastening bolt is threadedly connected to a first limit block in the reinforcement plate.

[0010] In this technical solution, the second pressing member includes a second pressing plate in the shape of a Chinese character "J". The second pressing plate is penetrated by fastening bolts. The connection method between the second pressing plate and the reinforcement plate is the same as that of the first pressing block.

[0011] In this technical solution, the pressure plates in the first pressure member and the second pressure member are fixedly connected to the reinforcement plate. The pressure plates can effectively press the photovoltaic panels, improve the stability of the photovoltaic panel setting, and prevent the photovoltaic panels from detaching from the mounting plates in strong winds, causing economic losses and endangering personal safety.

[0012] In the above technical solution, further, the driving unit includes a first motor, the first motor is fixedly connected to the support frame, the first motor is transmission-connected to the driving rod, the driving rod is rotationally connected to the support seat, the support seat is fixedly connected to the top of the support frame, and a connecting block is provided at the bottom of the mounting plate, and the connecting block and the driving rod are fixedly connected.

[0013] In the present technical solution, the transmission connection between the first motor and the driving rod is a common sprocket chain transmission connection, that is, sprockets are coaxially fixedly connected at the output end of the first motor and one side of the driving rod, and a chain is connected between the two sprockets. The driving rod is driven to rotate by the first motor, and the driving mounting plate is driven to rotate relative to the support frame so that it is parallel to the wind direction or at a certain angle, which can significantly reduce the area directly subjected to wind force, thereby reducing the structural load caused by wind pressure.

[0014] In the above technical solution, further, the support frame includes first support plates connected in an equilateral triangle, second support plates are connected between the first support plates, and the second support plates are connected to the middle parts of any adjacent first support plates.

[0015] In this technical solution, the first support plate and the second support plate are made of steel structural materials, such as steel or alloy steel, which have good compression and bending resistance. The support plates are designed in an equilateral triangle arrangement, which has high stability.

[0016] In the above technical solution, further, when the number of photovoltaic panels on the mounting plate is greater than one, a third pressure member is connected between the photovoltaic panels, and the third pressure member includes a third pressure plate in the shape of a "J". The middle part of the third pressure plate is threadedly connected to the mounting plate, and the third pressure plate can press the photovoltaic panels connected on both sides.

[0017] In this technical solution, the third pressure plate and the second pressure plate are similar in shape, both are in the shape of an inverted "J", and the middle part is threadedly connected to the mounting plate, which can effectively press the photovoltaic panels on both sides. In conjunction with the first pressure piece and the second pressure piece, the photovoltaic panels can be fully fixed to improve the safety and reliability of the overall structure.

[0018] In the above technical solution, further, a ventilation gap of 50-100 mm is left between the mounting plates.

[0019] In this technical solution, the size of this gap can be adjusted based on the specific installation environment and the size of the photovoltaic panel. For example, in snowy or windy areas, a larger gap may be required to allow for snow or wind to pass through. Furthermore, a well-designed gap can effectively prevent shadowing, improve heat dissipation, and facilitate maintenance and cleaning.

[0020] In the above technical solution, further, it also includes a wind direction sensor and a controller, and the wind direction sensor and the controller are electrically connected to the first motor.

[0021] In this technical solution, the wind direction sensor, the controller and the first motor are electrically connected. The wind direction and speed data provided by the wind direction sensor can be used to control the first motor to work through the controller, thereby driving the mounting plate to rotate. The wind direction sensor and the controller in this utility model are both existing technologies, and the electrical connection method is also a well-known attempt, so it will not be elaborated.

[0022] The beneficial effects of the utility model are:

[0023] 1. A photovoltaic panel is installed on the mounting plate, and a drive unit is installed between the mounting plate and the support frame. When there is strong wind, the drive unit drives the mounting plate to rotate relative to the support frame, making it parallel to the wind direction or at a certain angle. This can significantly reduce the area directly exposed to wind force, thereby reducing the structural load caused by wind pressure. By symmetrically arranging reinforcement plates on both sides of the bottom of the mounting plate, several mounting plates are connected in series, and the reinforcement plates are connected to a pressure component. The pressure component can connect the photovoltaic panel and the reinforcement plates, thereby improving the safety and reliability of the overall structure.

[0024] 2. The support frame includes first support plates connected in an equilateral triangle shape, second support plates connected between the first support plates, and the second support plates connected to the middle parts of any adjacent first support plates.

[0025] 3. Leave a 50-100mm ventilation gap between mounting panels. The size of this gap can be adjusted according to the specific installation environment and the size of the photovoltaic panels. For example, in snowy areas or areas with strong winds, a larger gap may be required to allow for snow accumulation or wind to pass through. At the same time, a reasonable gap design can effectively prevent shadows, improve heat dissipation, and facilitate maintenance and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
