Simultaneously, the GPS positioning module 6 continuously receives satellite signals to provide geographical coordinates for the device. When a suspected defect area is detected by the high-definition camera 5, the inspection vehicle 1 moves to the vicinity of the defect point and stops. Subsequently, the telescopic component starts working, extending the sampling component to reach directly above the defect point. Then, the lifting component is activated, causing the sampling component on the mounting plate 8 to gradually descend and collect samples from the defect point. Before collection, the dust and debris are blown away from the defect point by the dust blowing component to avoid interference with the sample.

Then, the lifting motor 13 drives the lead screw 11 to rotate, which drives the mounting plate 8 connected to it through the lead screw nut 12 to descend smoothly along the guide rod 14.

[0037] Reference Figure 4 Specifically: the soot blowing assembly includes a fan 30 fixedly installed on the mounting plate 8, and an air blowing hood 31 is fixedly installed at the air outlet of the fan 30;

[0038] Before drilling samples, the dust blowing assembly is started first.

[0041] Working principle: During the movement of the inspection vehicle 1, the high-definition camera 5 continuously collects images of the road surface. Simultaneously, the GPS positioning module 6 continuously receives satellite signals to provide geographical coordinates for the device. When a suspected defect area is detected by the high-definition camera 5, the inspection vehicle 1 moves to the vicinity of the defect point and stops. Subsequently, the telescopic component starts working, extending the sampling component to directly above the defect point. Then, the lifting component starts, causing the sampling component on the mounting plate 8 to gradually descend and collect samples from the defect point. Before collection, the dust and debris are blown away from the defect point by the dust blowing component to avoid interference with the sample.

[0042] The cylinder 10 pushes the sliding column 9 to slide outward inside the testing vehicle 1, thereby pushing out the fixing plate 7 and the entire sampling assembly. The guide wheel 32 ensures the smooth sliding of the sliding column 9. Then, the lifting motor 13 drives the lead screw 11 to rotate, which drives the mounting plate 8 connected to it through the lead screw nut 12 to descend smoothly along the guide rod 14.

[0043] Before drilling samples, the dust blowing assembly is started first. The fan 30 generates airflow and blows it through the air blowing hood 31 toward the road surface at the bottom of the sampling assembly, blowing away loose dust and debris to ensure that the collected samples are not affected by surface contaminants.

[0044] Then, the drilling motor 17 starts, transmitting power to the rotating shaft 16 through the drive wheel 18, belt 20, and driven wheel 19, driving the drill barrel 21 and drill bit 22 to rotate at high speed, while drilling the road surface. The drilled sample enters the drill barrel 21. The drill barrel 21 and rotating shaft 16, and the drill bit 22 and drill barrel 21 are all connected by threads, realizing quick replacement and modular combination. After drilling the sample, the two sub-tubes 25 can be opened to directly take out the sample of the disease point. At the same time, the water pump 26 can be started during the drilling process to draw water from the water tank 28 through the water suction pipe 27, and then pump it into the hollow rotating shaft 16 through the drain pipe 29, and finally flow into the drill barrel 21. This water flow can cool the drill bit 22. After drilling is completed, the lifting motor 13 reverses and lifts the mounting plate 8 and the sampling component with the obtained physical sample back to the initial position. Finally, the cylinder 10 is retracted to pull the entire sampling component back to the initial position.
