[0031] Slide grooves 10 are provided on both sides of the bottom of the protection box 3. The two slide grooves 10 are respectively located on the two sides of the glass cover 4, and one side of the inner wall of the two slide grooves 10 is slidably sleeved with sliders 11. The two sliders 11 are respectively fixedly installed on both sides of the top of the horizontal bar 7, and the two sliders 11 are located on both sides of the brush 8.

[0032] The two sides of the outer wall at the top of the protection box 3 are fixedly installed with fixing ears 12, and the inner cavity of the fixing ears 12 is threadedly connected with bolts 13, and the fixing ears 12 are fixedly installed on the bottom of the body 1 through the bolts 13. Among them, the setting of the two fixing ears 12 and the bolts 13 realizes the protection box 3 as a whole under the fixed assembly at the bottom of the body 1. When necessary, the protection box 3 can also be disassembled, thereby facilitating the inspection and maintenance of the internal mapping camera 5. Before disassembling the protection box 3, it is necessary to use the multi-section electric push rod 9 to drive the horizontal bar 7 so that it is horizontally away from the bottom of the protection box 3, and at this time, each slider 11 is also separated from each slide groove 10. The middle part of the four side ends of the protection box 3 is penetrated with a through groove 14, and the inner wall of each through groove 14 is fixedly installed with a filter 15, and the outer end surface of each filter 15 is flush with the outer wall of the protection box 3.

Buffer pads 18 are fixedly installed on the bottom of the two base frames 16, and the buffer pads 18 are made of rubber material.

[0034] The implementation principle of this embodiment is: when in use, the external remote controller controls the body 1 and the wings 2, so that the entire UAV equipment is in flight, and the glass cover 4 and the surveying and mapping camera 5 are used to realize aerial photography and mapping. In the process of flight and mapping, the dust and impurities adhered to the glass cover 4 are accumulated on the outer surface of the glass cover 4, thereby avoiding direct contamination of the lens on the surveying and mapping camera 5.

[0035] The multi-section electric push rod 9 can be controlled regularly so that it drives the horizontal bar 7 to perform horizontal reciprocating motion under the protective box 3, and at the same time, the dust and impurities adhered to the outer surface of the glass cover 4 can be cleaned by using the brush 8, so as to avoid affecting the mapping clarity of the mapping camera 5, and there is no need for the drone equipment to return for cleaning operations. During this process, the two sliders 11 slide and cooperate on the inner walls of the two slide grooves 10 respectively.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
