[0031] Furthermore, the transfer platform 2 includes a rectangular frame 2-1 and two groups of ear seats 2-2. The ear seats 2-2 are truss structures.

The first driving motor 3-1 is fixedly arranged vertically downward in the inner cavity of the rectangular frame 2-1, and the output shaft of the first driving motor 3-1 extends out of the bottom plate of the rectangular frame 2-1 and is arranged below.

[0032] Furthermore, the top surface of the rectangular frame 2-1 is fixedly connected to the bottom surface of the drone 1 through bolts. After the work is completed, the transfer platform 2 can be disassembled by removing the bolts, which is convenient and fast.

[0033] Furthermore, the material of the transfer platform 2 is a carbon fiber board. The carbon fiber board has good rigidity, high strength, high fatigue resistance and reliability, and is light in weight.

[0034] Furthermore, the X-axis rotation device 4 includes a rotating frame 4-1 and a second driving motor 4-2. The rotating frame 4-1 is an inverted "U" shape structure. The second driving motor 4-2 is fixedly arranged on the outside of a group of side plates of the rotating frame 4-1, and the output shaft of the second driving motor 4-2 passes through the side plate of the rotating frame 4-1 and is arranged between the two side plates of the rotating frame 4-1.

The middle part of the top surface of the rotating frame 4-1 is fixedly arranged at the bottom end of the output shaft of the first driving motor 3-1, and the first driving motor 3-1 drives the rotating frame 4-1 to rotate around the Z-axis.

[0035] Furthermore, a number of groups of reinforcing plates 4-3 are arranged between the top plate and the side plates of the rotating frame 4-1. The setting of the reinforcing plates 4-3 enhances the force-bearing strength of the rotating frame 4-1.

[0036] Furthermore, the negative pressure dust suction device 5 includes a fan barrel 5-1, a fan 5-2, a dust cup 5-3, a dust suction pipe 5-4 and a fixed frame 5-5, and the fixed frame 5-5 is symmetrically provided with fixed shafts 5-5-1 on both sides, and the fixed frame 5-5 is arranged between the two side plates of the rotating frame 4-1, and one group of the fixed shafts 5-5-1 is coaxially fixedly connected with the output shaft of the second drive motor 4-2, and the other group of the fixed shafts 5-5-1 is rotatably connected with the side plate of the rotating frame 4-1 on the same side, and the second drive motor 4-2 drives the fixed frame 5-5 to rotate around the X axis; the fixed frame 5-5 can rotate around the axis of the fixed shaft 5-5-1. The dust suction pipe 5-4 can be extended into some narrow gaps, which is convenient and efficient for dust treatment in various occasions.

[0037] The fan barrel 5-1 is fixed on the top surface of the fixing frame 5-5, the fan 5-2 is fixed in the fan barrel 5-1, and the dust cup 5-3 is fixed on the front side of the fixing frame 5-5; the front side wall of the dust cup 5-3 is provided with an air inlet 5-3-1, and the top of the dust cup 5-3 is provided with a plurality of air outlets 5-3-2, the air inlet 5-3-1 is connected with one end of the dust suction pipe 5-4, and the plurality of air outlets 5-3-2 are connected with the fan barrel 5-1 through pipes respectively; a filter screen 5-3-3 is provided in the dust cup 5-3, the filter screen 5-3-3 is a cylindrical structure, and a plurality of groups of filter holes are provided on the filter screen 5-3-3, and one side of the filter screen 5-3-3 is connected with the air inlet 5-3-1 of the dust cup 5-3; the other end of the dust suction pipe 5-4 is a flat structure. When vacuuming is required, the control system controls the fan 5-2 to work, and the fan 5-2 rotates at high speed to form a negative pressure difference. Under the action of the strong negative pressure difference, air and dust are sucked into the vacuum tube 5-4 in the form of negative energy, and then enter the filter 5-3-3 in the dust cup 5-3. The dust stays in the filter 5-3-3, and the air enters the fan barrel 5-1 from above and is discharged.

[0038] Further, a lighting device 7 is provided on the front side of the dust cup 5-3 above the dust suction pipe 5-4.

The material level sensor 8 detects the amount of dust in the filter 5-3-3. When too much dust accumulates, the material level sensor 8 transmits a signal to the control system, and the staff processes the filter 5-3-3.

[0040] Furthermore, the UAV is a multi-rotor UAV, which can take off and land vertically, hover in the air, and has a simple structure and flexible operation.

[0041] The working process of the present invention is as follows: when it is necessary to deal with dust at a place above the factory, the staff operates the drone 1 to move to the designated upper area, and the camera 6 captures and transmits the actual situation. According to the actual dust collection position, the control system controls the first drive motor 3-1 and the second drive motor 4-2 to work and adjusts the position of the negative pressure dust collection device 5.

[0042] After the position is adjusted, the control system controls the fan 5-2 to start working, and negative pressure is generated in the fan cylinder 5-1, so that the dust and air at the position to be vacuumed enter the filter 5-3-3 in the dust cup 5-3 through the vacuum pipe 5-4. After being filtered by the filter 5-3-3, the dust stays in the filter 5-3-3, and the air enters the fan cylinder 1 through the pipeline and is discharged. It can adapt to complex and chaotic steel beam structures.
