The left side of the first fixing plate 301 is rotatably connected to the first connecting block 307, and the right side of the first connecting block 307 is rotatably connected to the second connecting block 317. The right side of the first fixing plate 301 is fixedly connected to the sun position sensor 306. The outer wall of the first fixing plate 301 is fixedly connected to the telescopic rod 305. There are four telescopic rods 305, which are respectively fixedly connected to the four corners of the first fixing plate 301. The top of the telescopic rod 305 is fixedly connected to the microlens plate 304. By providing the focusing plate 316 and the microlens plate 304, the microlens plate 304 can use the focusing effect of the microlens to focus sunlight from a larger range to the light receiving area of the photovoltaic module. On the surface, not only the light intensity per unit area is increased, but also the photovoltaic module can absorb and utilize sunlight more effectively. The focusing plate 316 further converges and guides the light focused by the microlens plate 304. This secondary focusing effect can further increase the light intensity on the photovoltaic module, thereby improving the photoelectric conversion efficiency. By providing the microlens plate 304 and the telescopic rod 305, the microlens plate 304 can be freely adjusted in height, so that the microlens plate 304 can adjust the focal position of the light to better match the light-receiving surface of the photovoltaic module.

[0037] Working principle: When the weather is clear, the staff can start the equipment remotely. After receiving the start-up command, the control system sends a start-up signal to each component. After receiving the start-up signal, the first motor 206 starts to operate immediately. The first motor 206 drives the slide bar 205 to rotate. Because the cover plate 203, the waterproof layer 201 and the slide bar 205 are fixedly connected, the first motor 206 will drive the cover plate 203 and the waterproof layer 201 to retract. After retracting to the preset position, the hydraulic rod 208 is activated. The hydraulic rod 208 pushes the internal structure to rise smoothly until it reaches the preset optimal height, ensuring that the photovoltaic component can maximize the capture of sunlight without causing unnecessary shadows. Then the control system controls the second motor 406 to start, and the second motor 406 drives the lead screw 405 to rotate. The rotational motion is converted into linear motion through the sliding connection between the slider 404 and the lead screw 405, and the slider 404 and the support rod 402 adopt a rotational connection to limit its left and right movement, and the support rod 402 is rotationally connected to the third connecting block 408. Therefore, the power generated by the lead screw 405 drives the connecting rod 401 to move upward. The connecting rod 401 is fixedly connected to the first fixing plate 301, which is fixedly connected to the second connecting block 317. The second connecting block 317 is rotatably connected to the first connecting block 307, and the first connecting block 307 is fixedly connected to the connecting plate 403. Therefore, the first fixing plate 301 does not rise as a whole, but instead one end of the first fixing plate 301 rises in a fan shape, thereby achieving precise change in the angle of the photovoltaic module. The third motor 411 is started and drives the rotating plate 412 to rotate through the gearbox 410. The rotating plate 412 is fixedly connected to the connecting plate 403, and the second fixing plate 409 is slidably connected to the connecting plate 403. Therefore, the grab plate drives the connecting plate 403 to rotate, thereby enabling the photovoltaic module to rotate. The sun position sensor 306 sends a signal to the control system in real time according to the position of the sun. The control system controls the rotation and angle of the photovoltaic module based on the signal to ensure that the photovoltaic module always faces the sun to maximize the amount of direct sunlight it receives.

[0038] When the weather is bad, the staff can remotely shut down the equipment, and the control system will send corresponding signals to each component. The second motor 406 is started, and the second motor 406 drives the lead screw 405 to rotate. Through the cooperation of the slider 404, the connecting rod 401, the first fixing plate 301, the second connecting block 317, the connecting plate 403 and the support rod 402, the photovoltaic component is restored to a horizontal position. The third motor 411 is started, and through the cooperation of the gearbox 410, the rotating plate 412 and the connecting plate 403, the photovoltaic component is restored to its initial orientation. Then the hydraulic rod 208 contracts, driving the photovoltaic component back into the box body 1. Finally, the first motor 206 is started, driving the slide bar 205 to be guided by the roller 204, so that the waterproof layer 201 and the cover plate 203 are closed. The waterproof layer 201 can effectively prevent moisture from penetrating into the interior of the photovoltaic component, while the cover plate can prevent natural disasters such as wind, snow, hail or other foreign objects from directly impacting the photovoltaic component.
