step 1: connecting an unmanned aerial vehicle: connecting the mounting box 2 of the electric spark detection device to the lower part of the unmanned aerial vehicle;

step 2: adjusting the included angle of the plane: according to the characteristics of the actual high-rise steel structure to be detected, starting a steering engine 508 on one side, driving a cam plate 510 to extrude a driving motor 504 in contact with the cam plate forward by the steering engine 508 until a second end face gear 506 on an output shaft of the driving motor 504 is meshed with a first end face gear 405 in front of the driving motor, then starting the driving motor 504, driving a rotating shaft 404 in front of the driving motor 504 to rotate by gear transmission, driving the rotating shaft 404 on the other side to rotate synchronously by belt transmission, and driving one sliding block 408 on two sides to move forward and the other sliding block 408 on two sides to move backward due to the fact that the thread pitches of external threads on the rotating shafts 404 on two sides are the same and the rotating directions are opposite, so that the angle deflection of a sheet metal plate III 410 on the horizontal plane is realized, and finally the angle adjustment;

step 3: adjusting the space included angle: after the plane included angle adjustment in Step2 is completed, the enabled steering engine 508 is restored to an initial device, the started driving motor 504 is also synchronously restored to an initial position, at the moment, the gear 505 on the output shaft of the driving motor 504 is meshed with the gear ring 305 on the sheet metal pipe I302, the gear 505 on the output shaft of the driving motor 504 on the opposite side is always meshed with the gear ring 305, then the driving motor 504 on one side is enabled according to the characteristics of the actual high-rise steel structure to be detected, the driving motor 504 drives the sheet metal pipe I302 and the high-pressure probe 102 to rotate after gear transmission, the probe brush 103 at the front end is driven to synchronously rotate, and the probe brush 103 obtains a certain space included angle in a three-dimensional space;

step 4: hoisting the instrument: the detection instrument with the debugged state of the probe brush 103 in Step2 or Step3 is hoisted to the high-rise steel structure to be detected by the unmanned aerial vehicle, and the electric spark detection of the surface coating of the high-rise steel structure is started, and of course, the space attitude of the probe brush 103 can be adjusted in real time by the method of installing Step2 and Step3 according to the actual detection requirement in the detection process.

In summary, the electric spark detection device for the surface coating of the high-rise steel structure in the invention is applied in practice: the high-pressure probe 102 can be fixedly installed through the first hand-screwed screw 304 in the probe installation mechanism 3, the probe brush 103 can be fixedly installed through the second hand-screwed screw 402 in the probe brush installation mechanism 4, the space attitude of the probe brush 103 can be adjusted through the driving motor 504 and the steering engine 508 in the probe brush adjusting mechanism 5, and the host 101 can be fixedly installed through the third hand-screwed screw 602 in the host installation mechanism 6. The electric spark detection device disclosed by the invention is arranged below the unmanned aerial vehicle, so that the electric spark detection of the surface coating of the high-rise steel structure can be realized, and the practical problems that the existing electric spark detector is not easy to operate in the high-rise steel structure, and the overhead vehicle is expensive in use cost and limited in use place even if the overhead vehicle is used are solved. Therefore, the electric spark detection device for the surface coating of the high-rise steel structure has the characteristics of reasonable structure, convenience in disassembly and assembly, convenience in detection and strong adaptability to detection objects and detection environments.

The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
