Example 5: referring to fig. 2, 5 and 6, an unmanned aerial vehicle for highway surveying based on regional chain big data is basically the same as that in embodiment 1, further, a water tank 7 is fixedly connected to an inner wall of the top of a housing 1, a water pump 701 is fixedly connected to an inner wall of the housing 1, a second nozzle 704 is arranged on one side of a high-definition camera 404, an input end of the water pump 701 is connected with the water tank 7 through a first water pipe 702, and an output end of the water pump 701 is connected with the second nozzle 704 through a second water pipe 703; the water pump 701 is started, the water pump 701 can convey water in the water tank 7 into the second water pipe 703 through the first water pipe 702, and then the water is sprayed out through the second spray nozzle 704, so that dust attached to the high-definition camera 404 can be cleaned.

Example 6: referring to fig. 1 and 2, an unmanned aerial vehicle for highway surveying based on regional chain big data is basically the same as that in embodiment 1, and further, the upper end and the lower end of a hollow sleeve 101 are provided with filter screens 102; through the upper and lower both ends of filter screen 102 joint at hollow sleeve 101, can avoid the plastic bag that unmanned aerial vehicle descends to raise on the way to be drawn into screw 201.

Example 7: referring to fig. 2 and 5, an unmanned aerial vehicle for highway surveying based on regional chain big data is substantially the same as that of embodiment 1, and further, a non-slip mat 606 is fixedly connected to the bottom of the base 604; when unmanned aerial vehicle descends and contacts with ground, form for the preparation of rubber material through slipmat 606, can effectively play the antiskid effect to the friction on reducible base 604 and ground improves the life of base 604.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
