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. Embodiment

[0020] Please refer to Figure 1-4, a dust removal device for a photovoltaic panel used in photovoltaic power generation, including a fixed platform 1. An installation groove 2 is formed in the middle of the fixed platform 1. Support legs 3 are fixedly connected to the bottom of the fixed platform 1. A dust removal device is arranged at the upper end of the fixed platform 1. The dust removal device includes a fixed frame 401. The fixed frame 401 is fixedly connected to the upper end of the fixed platform 1. A spring A 402 is fixedly connected to the inner top of the fixed frame 401. The bottom of the spring A 402 is fixedly connected to a mounting plate 403. The bottom of the mounting plate 403 is fixedly connected to a U-shaped plate 404. A connecting block 405 is movably connected inside the U-shaped plate 404. A fixed block 406 is fixedly connected to the upper end of the mounting plate 403. An installation cavity 407 is formed inside the fixed block 406. A moving rod A 408 is slidably connected to the right side of the fixed block 406. A stop block 409 is fixedly connected to one end of the moving rod A 408 located inside the installation cavity 407. A spring B 410 is movably sleeved outside the moving rod A 408. The two ends of the spring B 410 are respectively fixedly connected to the inner wall of the installation cavity 407 and the stop block 409. A moving rod B 411 is slidably connected to the lower end of the fixed block 406. The bottom of the moving rod B 411 penetrates through the U-shaped plate 404. A push block 412 is fixedly connected to the top of the moving rod B 411. A spring C 413 is movably sleeved outside the moving rod B 411. The two ends of the spring C 413 are respectively fixedly connected to the push block 412 and the installation cavity 407. A positioning hole 414 is formed in the upper end of the connecting block 405. A dust removal roller 415 is rotatably connected between the connecting blocks 405.

[0021] The parts of the two ends of the mounting plate 403 located inside the fixed frame 401 are slidably connected to the inner wall of the fixed frame 401.

[0022] The upper end of the push block 412 and the side surface of the stop block 409 are both provided with inclined surfaces and are matched with each other.

[0023] The inner diameter size of the positioning hole 414 is the same as the outer diameter of the moving rod B 411.

[0024] In this embodiment, by setting the dust removal device, when dust removing photovoltaic panels with different thicknesses, the dust removal roller 415 can always be kept in close contact with the surface of the photovoltaic panel 3, and at the same time, it is convenient to replace the dust removal roller 415, so as to ensure the dust removal effect.

[0025] During use, when the dust removal roller 415 needs to be replaced, pull the moving rod A408 outward, so that it compresses the spring B410 and drives the stopper 409 to move outward. Then, the push block 412 will lose its restriction, and under the action of the spring C413, it will push the push block 412 upward, driving the moving rod B411 upward, and then leaving the inside of the positioning hole 414 at the upper end of the connecting block 405. Then, the connecting block 405 can be pulled out from the side of the C-shaped plate 404. Then, a new connecting block 405 is placed inside the C-shaped plate 404. At this time, release the moving rod A408. It should be noted that the elastic force of the spring B410 is greater than that of the spring C413. Then, under the action of the spring B410, it will drive the stopper 409 to move inward, and then push the push block 412 downward, driving the moving rod B411 into the inside of the positioning hole 414, so that the new connecting block 405 and the dust removal roller 415 can be replaced. At the same time, the spring A402 will always ensure that the dust removal roller 415 is in close contact with the surface of the photovoltaic panel 3. Embodiment
