Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically a dynamic load adaptive photovoltaic support. Background Technology

[0002] To facilitate the installation of photovoltaic (PV) modules, they are typically mounted on support structures. Traditional PV support structures usually employ fixed-angle installations or rely on motors or hydraulic systems to adjust the angle to adapt to environmental changes. However, this design has several drawbacks: motors or hydraulic systems require continuous power supply, making them prone to failure in remote areas or severe weather, resulting in high maintenance costs; under strong winds, the large windward area of ​​the PV panels, coupled with the lack of a buffer structure on the support structure, makes it susceptible to wind pressure impacts that can cause structural deformation or overturning; when snow covers the PV panels, manual cleaning or single-electric heating for snow removal is required, which is inefficient and energy-intensive; some adjustable support structures cannot automatically reset after the wind pressure dissipates, requiring manual intervention. For example, CN119602683A discloses a high-wind protection device for PV tracking support structures, which reduces wind resistance by deploying a protective plate, but requires complex mechanical linkages and cannot address snow accumulation issues; CN220830426U discloses a self-adjusting PV support structure that relies on an electric push rod to adjust the support height, which is energy-intensive and cannot adapt to environmental changes. Therefore, there is an urgent need for a photovoltaic support system that does not require continuous power supply and can adapt to wind pressure and snow accumulation. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The gradual rotator 4 includes a cylindrical body 41 and a base 42. A rotating shaft 43 is fixedly connected to the middle of the cylindrical body 41, and a circular block 44 is fixedly connected to the middle of the rotating shaft 43. The surface of the circular block 44 is provided with a first arc-shaped groove 45 and a second arc-shaped groove 46. A first torsion spring 47 is provided on the top of the base 42, with one end of the first torsion spring 47 extending into the second arc-shaped groove 46. A second torsion spring 48 is fixedly connected to the top of the inner wall of the cylindrical body 41, with one end of the second torsion spring 48 extending into the first arc-shaped groove 45. A damping ring 49 is provided on the side of the circular block 44 and slides against the inner wall of the cylindrical body 41. A connecting flange 411 is fixedly connected to one end of the rotating shaft 43, and a connecting flange 411 is fixedly connected to the top of the base 42. The rotating support 410 adapted to shaft 43 is fixedly connected to the bottom of the fixed base 5 and the connecting flange 411. When the fixed base 5 rotates around the rotating shaft 43 in one direction, one side of the second arc groove 46 is blocked by the first torsion spring 47 and rotates slowly. At the same time, one end of the second torsion spring 48 located in the first arc groove 45 moves freely along the length of the first arc groove 45.

The transverse auxiliary groove 133 is an arc-shaped groove with a radius of curvature of 10mm. The transverse auxiliary groove 133 has a depth of 3mm and a width of 2mm. The surfaces of the longitudinal main groove 132 and the transverse auxiliary groove 133 are provided with a superhydrophobic coating. The superhydrophobic coating is a sprayed fluorosilane nano-coating with a thickness of 50nm.

[0043] When the photovoltaic panel 13 is subjected to frontal wind force, the elastic support rod 11 is compressed, the movable seat 9 slides along the connecting shaft 15 and compresses the first spring 17, thereby reducing the tilt angle of the photovoltaic mounting frame 8; when subjected to lateral wind force, one side of the elastic support rod 11 is compressed and the other side of the elastic support rod 11 is extended, and the fixed base frame 5 drives the gentle rotator 4 to rotate to reduce wind pressure; the gentle rotator 4 can rotate in both directions, and when there is no wind, the torsion spring built into the gentle rotator 4 drives the fixed base frame 5 to reset; the heating wire 134 is linked with the electric telescopic rod 14 to heat and de-ice in snowy environments and vibrate the photovoltaic mounting frame 8 to shake off the snow.

[0044] Supporting rollers 6 are fixedly connected to the four corners of the bottom of the fixed base frame 5. The surface of the rotating base 3 is provided with arc-shaped grooves that are adapted to the supporting rollers 6.

The connecting ball head 76 is movably connected to one side of the photovoltaic mounting frame 8. When wind blows onto the photovoltaic panel surface, it generates a downward vertical force. The spring-loaded support 7 can reduce the vibration of the photovoltaic panel caused by wind.

[0046] The elastic support rod 11 includes a hollow rod 111 and a solid rod 112. The solid rod 112 is slidably connected to the hollow rod 111, and one end of the solid rod 112 extends into the interior of the hollow rod 111. One end of the hollow rod 111 is fixedly connected to a damper 114 that is slidably connected to the inner wall of the hollow rod 111.

Through the second spring 115 and the third spring 116, the elastic support rod 11 can contract and extend, thus playing a buffering role when dealing with lateral wind forces.

[0047] An ultrasonic snow depth sensor 19 is fixedly connected to the edge of the photovoltaic mounting frame 8, and a control box 20 is fixedly connected to the bottom side of the connecting beam 2. The output end of the ultrasonic snow depth sensor 19 is electrically connected to the controller inside the control box 20. The controller controls the start and stop of the electric telescopic rod 14 and the heating wire 134 according to the snow depth data, so as to automatically remove the snow on the surface of the photovoltaic panel, avoiding manual cleaning or natural melting, and improving the efficiency of photovoltaic power generation.

[0048] A wind speed sensor 21 is also installed on one side of the connecting beam 2. The wind speed sensor 21 is electrically connected to the controller in the control box 20. The controller adjusts the extension and retraction of the electric telescopic rod 14 according to the wind speed sensor signal, and adjusts the tilt angle of the photovoltaic mounting frame 8. When dealing with strong winds, i.e., wind speeds exceeding 20 m / s, the tilt angle is actively reduced, thereby reducing the pressure on the photovoltaic panel.

[0049] The top of the fixed base 5 is fixedly connected to a T-shaped slide rail that is compatible with the movable seat 9. The length direction of the T-shaped slide rail is consistent with the length direction of the connecting shaft 15, which ensures the stability of the movable seat 9.
