Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: an automatic snow removal mechanism for a solar panel photovoltaic module, including a substrate 1, a track groove 2, a track rod 3, a movable plate 4, a bottom pulley 5, a bottom plate 6, a limit groove 7, a return spring 8, a servo motor 9, a cam 10, a drag-reducing roller 11, a vertical plate 12, a spring telescopic rod 13, a mounting bracket 14, a photovoltaic panel 15, a middle frame 16, a trigger plate 17 and a middle pulley 18. A track groove 2 is opened on the substrate 1, a track rod 3 is fixedly installed in the track groove 2, the track rod 3 penetrates through a hole horizontally opened in the middle of the movable plate 4, the movable plate 4 is arranged in the track groove 2, a bottom pulley 5 is installed on the bottom surface of the movable plate 4, and the bottom end of the bottom pulley 5 is attached to the inner bottom surface of the track groove 2. One end of the top surface of the substrate 1 is fixedly installed with a servo motor 9, a cam 10 is fixedly installed on the output shaft of the servo motor 9, one end of the cam 10 is attached to the drag-reducing roller 11, the drag-reducing roller 11 is rotatably installed on the side surface of the vertical plate 12, the vertical plate 12 is fixedly installed on the top surface of the substrate 1, a spring telescopic rod 13 is fixedly installed on the top surface of the movable plate 4, the top end of the spring telescopic rod 13 is fixed with a mounting bracket 14, a photovoltaic panel 15 is installed at the top end of the mounting bracket 14, the edge of the top surface of the substrate 1 is connected and fixed to the bottom end of the middle frame 16, a trigger plate 17 is fixed on the top surface of the middle frame 16, one end of the trigger plate 17 is attached to the bottom end of the middle pulley 18, and the middle pulley 18 is rotatably installed at the center of the bottom surface of the mounting bracket 14.

[0021] The hole horizontally opened in the middle of the movable plate 4 in this example is in sliding connection with the track rod 3, and the track rods 3 are horizontally symmetrically distributed about the center of the movable plate 4. The above structural design ensures that the movable plate 4 can perform a stable horizontal sliding displacement along the track rod 3.

[0022] A bottom plate 6 is fixedly installed on the bottom surface of the movable plate 4. The bottom end of the bottom plate 6 is attached to one end inside the limit groove 7. The limit groove 7 is opened on the inner bottom surface of the track groove 2. A return spring 8 is fixedly installed on one side of the bottom plate 6. The end of the return spring 8 is fixed to the other end inside the limit groove 7. The above structural design enables the protruding part of the cam 10 to push the vertical plate 12 and the movable plate 4 to move horizontally by squeezing the resistance reduction roller 11, and the bottom plate 6 can move horizontally synchronously and squeeze the return spring 8 to store elastic potential energy.

[0023] The cams 10 are symmetrically distributed about the center of the vertical plate 12. The resistance reduction rollers 11 are densely installed at equal intervals on the vertical plate 12. The above structural design enables the cam 10 to stably rotate to push the resistance reduction rollers 11 on the vertical plate 12 and drive the vertical plate 12 and the movable plate 4 to move stably horizontally.

[0024] The spring telescopic rods 13 are symmetrically distributed about the center of the mounting frame 14. The linear distance between the spring telescopic rods 13 and the side surface of the middle frame 16 is greater than the length of the limit groove 7. The above structural design can ensure the stability of the mounting frame 14 and ensure that when the movable plate 4 drives the middle frame 16 to move horizontally, it will not collide with the spring telescopic rods 13.

[0025] The middle pulleys 18 are equally spaced at the bottom end of the trigger plate 17. The joint surface between the trigger plate 17 and the middle pulleys 18 is set as an arc surface. The above structural design enables the middle pulleys 18 to be squeezed by the arc surface of the trigger plate 17 when moving horizontally and drive the mounting frame 14 to move vertically stably.

[0026] Working principle: When using this device, control the servo motor 9 to drive the cam 10 to rotate stably in one direction. When the cam 10 rotates, its protruding part first squeezes and pushes the resistance reduction roller 11 to push Figure 2 the vertical plate 12 and the movable plate 4 in the middle to slide horizontally to the left along the track groove 2. When the movable plate 4 moves to the left, it drives the bottom plate 6 to slide horizontally along the limit groove 7 and squeeze the return spring 8. Then the protruding part of the cam 10 rotates away from the resistance reduction roller 11, and the vertical plate 12 and the movable plate 4 slide to the right and reset under the elastic force of the return spring 8. In this way, the movable plate 4 drives the spring telescopic rod 13, the mounting frame 14 and the photovoltaic panel 15 to perform small horizontal vibrations;

[0027] At the same time, the mounting frame 14 drives the middle pulleys 18 to displace synchronously. When the middle pulleys 18 move to the left following the mounting frame 14 in the middle, they are squeezed by the curved surface of the trigger plate 17 and rise. The middle pulleys 18 drive the mounting frame 14 and the photovoltaic panel 15 to rise and stretch the spring telescopic rods 13. Then when the middle pulleys 18 follow Figure 2 the mounting frame 14 in the middle to move to the left, Figure 2When the mounting bracket 14 moves rightward and resets, the middle pulley 18 moves away from the trigger plate 17. Under the elastic force of the spring telescopic rod 13 and the gravity of the mounting bracket 14 and the photovoltaic panel 15, the mounting bracket 14 and the photovoltaic panel 15 move downward and reset. In this way, the mounting bracket 14 and the photovoltaic panel 15 vibrate vertically while following the movable plate 4 to perform horizontal vibration, quickly shaking off the snow on the surface of the photovoltaic panel 15. This is the working principle of the automatic snow removal mechanism of this solar panel photovoltaic module.
