[0035] A substrate 20 is fixedly connected to the side of the photovoltaic panel 19, and a dust removal mechanism is arranged inside the substrate 20. The dust removal mechanism includes a second motor 21 arranged inside the substrate 20, and a transmission rod 22 is arranged at the output end of the second motor 21. A gear 23 is fixedly connected to the side of the transmission rod 22 away from the second motor 21, and a rack belt 24 is meshed and connected to the side of the gear 23. An elastic wiper 25 is fixedly connected to the side of the rack belt 24 away from the gear 23. The operation of the second motor 21 causes the elastic wiper 25 to change from a static state to a sliding state outside the photovoltaic panel 19;

[0036] The protection box 1 is fixedly connected to the bottom plate 2, the threaded rod 4 is rotatably connected to the bottom plate 2, and the movable frame 5 is slidably connected to the bottom plate 2;

[0037] The first telescopic bracket 6 is rotatably connected to a first sliding rod 7 on one side close to the bottom plate 2;

[0038] A slide groove 8 is provided inside the upper part of the bottom plate 2, and the slide groove 8 is slidably connected to the first slide rod 7;

[0041] The base plate 20 and the second motor 21 are fixedly connected, and the elastic wiper plate 25 and the photovoltaic panel 19 are slidably connected.

[0042] In this embodiment, the protection mechanism provided inside the protection box 1 is started, and the first motor 3 fixedly installed above the base plate 2 in the protection mechanism starts to run. When the first motor 3 is running, it starts to control the threaded rod 4 provided at its output end to rotate, and the other end of the threaded rod 4 rotates outside the base plate 2. The threaded rod 4 is externally threadedly connected with a moving frame 5. When the threaded rod 4 rotates inside the moving frame 5, a spiral force is generated.

When the support plate 10 descends, the second telescopic bracket 11 rotatably connected between the bottom plate 2 and the support plate 10 will also shrink. When the support plate 10 descends, it drives the bracket rod 12 fixedly connected thereto to descend. The bracket rod 12 drives the photovoltaic panel 19 and other components arranged thereon to descend, so that they all descend to the inside of the protection box 1. When the wind is strong or there are debris hitting, it can play a good protective role.

[0043] A substrate 20 is fixedly connected to the side of the photovoltaic panel 19, and a dust removal mechanism arranged inside the substrate 20 is started. The second motor 21 fixedly connected to the inside of the substrate 20 in the dust removal mechanism starts to run. When the second motor 21 runs, it starts to control the transmission rod 22 arranged at its output end to rotate. A gear 23 is fixedly connected to the side of the transmission rod 22 away from the second motor 21. When the transmission rod 22 rotates, it drives the gear 23 to start rotating. When the gear 23 rotates, it drives the rack belt 24 meshing with its side to start rotating. An elastic wiper plate 25 is fixedly connected above the rack belt 24. When the rack belt 24 moves, it drives the elastic wiper plate 25 to start moving. An elastic convex body is arranged on the surface of the elastic wiper plate 25, and the elastic wiper plate 25 is slidably connected to the outside of the photovoltaic panel 19, so that the elastic wiper plate 25 starts to slide on the outside of the photovoltaic panel 19 to remove dust on the outside of the photovoltaic panel 19.

[0047] The side of the rack belt 24 away from the gear 23 is meshedly connected with a rack rod 26 , and the side of the rack rod 26 away from the rack belt 24 is rotationally connected to the base plate 20 .

[0048] In this embodiment, a first driving assembly 13 is arranged above the bracket rod 12. When the first driving assembly 13 is in operation, it can drive the gear transmission assembly 14 arranged at its output end to start rotating. A main bracket 15 is fixedly connected above a gear inside the gear transmission assembly 14. When the gear transmission assembly 14 rotates, the main bracket 15 starts to rotate. The main bracket 15 can drive the photovoltaic panel 19 arranged above it to rotate 360 ​​degrees on the plane.
