Description

Technical Field

[0001] This utility model relates to the field of rooftop photovoltaic technology, specifically to an adjustable-angle rooftop photovoltaic wind-resistant fixing device. Background Technology

[0002] Rooftop photovoltaics, also known as distributed photovoltaics, refers to a technology that installs solar panels on the roofs of residential, commercial, or industrial buildings to directly convert solar energy into electrical energy. With the continuous development of rooftop photovoltaic technology, various rooftop photovoltaic devices have emerged, such as an adjustable-angle rooftop photovoltaic wind-resistant fixing device.

[0003] Currently, most rooftop solar panels on the market are directly fixed to the roof with bolts. This results in a loose connection between the panels and the roof, and unstable fixing of the components to the brackets. Strong winds can easily enter from under the tilted solar panels, generating an upward force that could cause the entire panel to be overturned or fall off. Furthermore, the tilt angle of the rooftop solar panels is fixed after installation, making later adjustments difficult. Therefore, we propose an adjustable-angle rooftop solar wind-resistant fixing device that can guide the airflow upwards from the tilted solar panels, reducing the risk of overturning, and allows for quick adjustment of the panel tilt angle later on. It is also easy to operate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable-angle rooftop photovoltaic wind-resistant fixing device. It has the advantages of guiding the wind flow of the tilted photovoltaic panels upward, reducing the risk of overturning, and allowing for quick adjustment of the photovoltaic panel's tilt angle later. It is also simple to operate. This solves the problems of current rooftop photovoltaic panels, which are generally fixed to the roof with bolts. Strong winds can easily enter from under the tilted photovoltaic panels, generating an upward force through the tilted panels, posing a risk of overturning or falling off. Furthermore, the tilt angle of the rooftop photovoltaic panels is fixed after installation, making subsequent adjustments difficult.

[0005] To achieve the above-mentioned goals of guiding the wind flow of tilted photovoltaic panels upward, reducing the risk of overturning, and allowing for quick adjustment of the photovoltaic panel's tilt angle in the later stages, with simple operation, this utility model provides the following technical solution: an adjustable-angle roof photovoltaic wind-resistant fixing device, including a fixing box, a connecting rod fixedly connected to the right side of the fixing box, a fixing block fixedly connected to the right side of the connecting rod, a photovoltaic panel body movably connected to the top of the fixing block, and an adjustment mechanism provided at the bottom of the photovoltaic panel body; The adjustment mechanism includes a fixed plate, a side baffle, an extension plate, a rubber column, a threaded rod, a lead screw assembly, a movable block, and a movable rod. The fixed plate is fixedly connected to the left side of the photovoltaic panel body. The side baffle is movably connected to the bottom of the fixed plate. An extension plate is provided at the bottom of the side baffle. A rubber column is fixedly connected to the bottom of the extension plate. A threaded rod is provided inside the fixed box. A lead screw assembly is provided outside the threaded rod. A movable block is fixedly connected to the top of the lead screw assembly. A movable rod is fixedly connected to the top of the movable block.

[0006] Furthermore, two sliders are fixedly connected to the outside of the extension plate, and the outside of the side baffle is provided with a groove that matches the two sliders.

[0007] Furthermore, a fixed cylinder is welded to the bottom of the photovoltaic panel body, and a rotating rod is provided inside the fixed cylinder. The movable rod is movably connected to the photovoltaic panel body through the rotating rod and the fixed cylinder.

[0008] Furthermore, a bearing is provided inside the fixing box, and the threaded rod is movably connected to the fixing box through the bearing.

[0009] Furthermore, a handle is fixedly connected to the outside of the threaded rod, and the outside of the threaded rod is provided with a frosted texture.

[0010] Furthermore, the top of the fixed box is provided with a movable groove, and the movable block is adapted to the movable groove.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: This adjustable-angle rooftop photovoltaic wind-resistant fixing device, through the setting of an adjustment mechanism, allows for the fixing of the fixing box and fixing block to the roof with ground nails when the photovoltaic panels need to be fixed. Then, by rotating the threaded rod, the screw assembly moves to the right, thereby pushing the movable block to move horizontally, and the elevation angle of the photovoltaic panel body can be adjusted. At the same time, the extension plate moves downward on the side baffle, thereby blocking the wind on the left. The wind blowing left and right only generates a downward force, and passes forward and backward without resistance. This adjustment mechanism can guide the airflow of the tilted photovoltaic panel upward, reducing the risk of overturning, and can quickly adjust the elevation angle of the photovoltaic panel later. The operation is simple. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 An adjustable-angle rooftop photovoltaic wind-resistant fixing device in this embodiment includes a fixing box 1, a connecting rod 2 fixedly connected to the right side of the fixing box 1, a fixing block 3 fixedly connected to the right side of the connecting rod 2, a photovoltaic panel body 4 movably connected to the top of the fixing block 3, and an adjustment mechanism 5 provided at the bottom of the photovoltaic panel body 4. The adjustment mechanism 5 includes a fixed plate 501, a side baffle 502, an extension plate 503, a rubber column 504, a threaded rod 505, a lead screw assembly 506, a movable block 507, and a movable rod 508. The fixed plate 501 is fixedly connected to the left side of the photovoltaic panel body 4. The side baffle 502 is movably connected to the bottom of the fixed plate 501. An extension plate 503 is provided at the bottom of the side baffle 502. The rubber column 504 is fixedly connected to the bottom of the extension plate 503. The threaded rod 505 is provided inside the fixed box 1. The lead screw assembly 506 is provided outside the threaded rod 505. The movable block 507 is fixedly connected to the top of the lead screw assembly 506. The movable rod 508 is fixedly connected to the top of the movable block 507.

[0016] In the implementation of the case, the extension plate 503 is externally fixedly connected to two sliders 6, and the side baffle 502 is externally provided with a sliding groove 7 that matches the two sliders 6. The cooperation between the sliders 6 and the sliding groove 7 provides precise guidance for the up and down movement of the extension plate 503, ensuring that it remains stable and does not tilt during the adjustment process. This design allows the extension plate to extend and retract smoothly and always maintain a tight fit with the side baffle, thereby continuously and effectively blocking the airflow below when the angle of the photovoltaic panel changes, enhancing the reliability of the wind resistance effect.

[0017] In the implementation of the case, a fixed cylinder 8 is welded to the bottom of the photovoltaic panel body 4. A rotating rod is set inside the fixed cylinder 8. The movable rod 508 is movably connected to the photovoltaic panel body 4 through the rotating rod and the fixed cylinder 8. The fixed cylinder 8 and the rotating rod form a sturdy and flexible hinge point, which converts the linear thrust of the movable rod 508 into the rotational motion of the photovoltaic panel, realizing stepless adjustment of the angle. At the same time, this structure evenly transmits the force on the adjustment mechanism to the photovoltaic panel frame, avoiding stress concentration and improving the structural strength and durability of the entire device.

[0018] In the implementation of the case, the fixed box 1 is equipped with a bearing 9 inside. The threaded rod 505 is movably connected to the fixed box 1 through the bearing 9. The bearing 9 greatly reduces the frictional resistance when the threaded rod 505 rotates, making it easier and smoother to adjust the angle through the handle 10. It ensures the concentricity of the threaded rod 505, making it run smoothly and avoiding jamming and wear, thereby improving the operating experience of the adjustment process and the service life of the device.

[0019] In the case implementation, the threaded rod 505 is externally fixedly connected to a handle 10. The threaded rod 505 has a frosted texture on its exterior. The handle 10 provides a good human-machine interface, making it convenient for construction personnel to apply force. The frosted texture (or anti-slip texture) on the threaded rod 505 significantly increases the friction between the hand and the handle, preventing slippage during adjustment and ensuring safe, accurate and efficient operation.

[0020] In the implementation of the case, the top of the fixed box 1 is provided with a movable groove 11, and the movable block 507 is adapted to the movable groove 11. The movable groove 11 provides a limited path for the movement of the movable block 507, ensuring that it can only perform horizontal linear motion, thereby accurately converting the rotational motion of the lead screw assembly into linear thrust. This not only ensures the accuracy of angle adjustment, but also prevents the movable block from twisting or shifting during the movement, playing a key role in the stability and reliability of the entire transmission system.

[0021] When implementing this procedure, please follow these steps: 1) When it is necessary to fix the photovoltaic panels, first fix the fixing box 1 and fixing block 3 to the roof with ground nails; 2) Then, by rotating the threaded rod 505, the screw assembly 506 moves to the right, thereby pushing the movable block 507 to move horizontally, and the elevation angle of the photovoltaic panel body 4 can be adjusted. 3) Then, the extension plate 503 moves downward on the side baffle 502 to block the wind on the left side; 4) Finally, the wind blowing left and right will only generate a downward force, and there will be no resistance when passing forward and backward.

[0022] In summary, this adjustable-angle rooftop photovoltaic wind-resistant fixing device, through the setting of the adjustment mechanism 5, allows for the following steps when fixing the photovoltaic panels: first, the fixing box 1 and fixing block 3 are fixed to the roof with ground nails; then, by rotating the threaded rod 505, the screw assembly 506 moves to the right, thereby pushing the movable block 507 to move horizontally, thus adjusting the elevation angle of the photovoltaic panel body 4. At the same time, the extension plate 503 moves downward on the side baffle 502, thereby blocking the wind from the left. The wind blowing left and right only generates a downward force, and passes forward and backward without resistance. This adjustment mechanism 5 can guide the wind flow of the tilted photovoltaic panel upward, reducing the risk of overturning, and can quickly adjust the elevation angle of the photovoltaic panel later, making it simple to operate.
