[0029] The roadblock clearing mechanism 2 includes: a support plate 201, a first cylinder 202, a roadblock clearing shell 203, an air jet hole 204, a flexible air pipe 205, a first air pump 206, a driving motor 207, and a spiral brush 208. The support plate 201 is connected to one side of the trolley 1 by bolts. The first cylinder 202 is connected to the bottom of the support plate 201. The roadblock clearing shell 203 is connected to the bottom of the first cylinder 202. The air jet hole 204 is opened at the bottom of the roadblock clearing shell 203. The flexible air pipe 205 is connected above the roadblock clearing shell 203. The other end of the flexible air pipe 205 is connected to the first air pump 206.

The other end of the spiral brush 208 is rotatably connected to the inner wall of the roadblock clearing shell 203.

[0030] During specific implementation, the first cylinder 202 is activated to push the obstacle-removing shell 203 downward, bringing the spiral roller brush 208 into contact with the ground. When encountering a relatively large obstacle, the obstacle is pushed aside by the obstacle-removing shell 203. The first air pump 206 sends external air into the obstacle-removing shell 203 and then sprays it out onto the ground through the air nozzles 204, blowing up smaller obstacles such as dust in the depressions. Then, the drive motor 207 drives the spiral roller brush 208 to rotate, sweeping the smaller obstacles on the ground to one side to prevent them from affecting road surface detection, so as to enable the road surface damage detection device to remove obstacles.

[0031] Refer to Figure 1 、 Figure 5 and Figure 6 It can be seen that the marking mechanism 7 includes: a storage tank 701, a flexible liquid pipe 702, a shunt pipe 703, a solenoid valve 704, a nozzle 705, an adapter plate 706, and a second air pump 707. The upper surface of the trolley 1 near the U-shaped plate 801 and the control cabinet 3 is bolted with a storage tank 701. One side of the storage tank 701 is connected with a flexible liquid pipe 702. The flexible liquid pipe 702 passes through the inner wall of the trolley 1 and is connected with a shunt pipe 703. The lower part of the shunt pipe 703 is connected with a solenoid valve 704. The lower part of the solenoid valve 704 is connected with a nozzle 705. One side of the solenoid valve 704 is connected with an adapter plate 706. The adapter plate 706 is connected to one side of the housing 804. The upper surface of the control cabinet 3 is connected with a second air pump 707. The second air pump 707 is connected to one side of the storage tank 701.

[0032] During specific implementation, the second air pump 707 is activated to send external air into the storage tank 701, increasing the pressure inside the storage tank 701. The pigment in the storage tank 701 is sent into the shunt pipe 703 through the flexible liquid pipe 702. After being distributed by the shunt pipe 703, it is sent into multiple groups of solenoid valves 704. When road surface damage is detected, the nearby solenoid valve 704 is opened, and the pigment is sprayed out from the nozzle 705 to mark the road surface, so as to enable the road surface damage detection device to mark the damaged road surface.

[0033] In summary, when using the pavement damage detection device with an obstacle clearing structure, first, pour the pigment into the storage tank 701. Connect the pavement damage detection device to the vehicle through the hanging parts on one side, or manually push the pavement damage detection device to move it. Start the second cylinder 802 to make the roller 807 contact the ground, and start the first cylinder 202 to make the spiral brush 208 contact the ground. Then start the second air pump 707 to pressurize the storage tank 701. The obstacle clearing shell 203 pushes larger obstacles to one side, and the air jet holes 204 eject high-pressure gas to blow up impurities. The drive motor 207 drives the spiral brush 208 to rotate to sweep the impurities to one side. When the roller 807 encounters a damaged pothole beside the road, the spring 808 pushes the roller 807 into the pothole. The infrared distance sensor 809 emits infrared light and receives it after being reflected by the outer ring rod 806. Calculate the distance based on the time from when the infrared light is emitted to when it is received and the propagation speed of the infrared light. If the fluctuation range of the distance is large, the pavement at that place is damaged. Open the nearby solenoid valve 704 to eject the pigment for marking. The camera 6 records the image of the pavement in real time and takes pictures of the marked places. At the same time, the FPGA control device 4 stores the damaged positions recorded by the positioning device 5 and the images taken by the camera 6. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
