Description

Technical Field

[0001] This utility model relates to the field of underground disease detection, specifically to a radar detection device for underground road diseases. Background Technology

[0002] Underground road defects generally include cavities, voids, loose structures, and water-rich structures. To ensure the safe and stable operation of urban infrastructure and eliminate the safety hazards posed by underground cavities, geological exploration is necessary. Ground-penetrating radar (GPR) technology, as an emerging and popular technology in the field of exploration, is widely used in the detection of underground road defects due to its non-destructive, rapid, and accurate detection characteristics, playing a crucial role in preventing road collapse accidents.

[0003] The existing technology has the following shortcomings: The radar signals emitted by the existing road underground defect radar detection devices are usually emitted vertically downwards from the ground. However, in urban environments, there are many areas with dense underground pipelines. The dense underground pipelines may cause radar signals to overlap and become confused, affecting the clarity and reliability of the measurement data. Furthermore, underground pipes, rocks, roots and other foreign objects may also cause radar signal reflection and scattering, resulting in serious interference and greatly affecting the data interpretation efficiency of the road underground defect radar detection device.

[0004] Therefore, it is necessary to invent and improve a new type of radar detection device for underground road defects. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road underground defect radar detection device, comprising a detection vehicle body, a camera fixedly installed at the front end of the detection vehicle body, a first radar transmitter fixedly installed at the center of the bottom surface of the detection vehicle body, the first radar transmitter being used to detect road underground defects vertically downwards, a slide rail being provided at the center of the top surface of the detection vehicle body, the slide rail extending to the end of the detection vehicle body away from the camera, a detachable detection device being installed inside the slide rail, the detachable detection device being used to separate the detection vehicle body and detect the area below the first radar transmitter obliquely.

[0006] Preferably, the detachable detection device includes a detachable vehicle body, which has a U-shaped structure and is slidably installed in a slide rail.

[0007] Preferably, grooves are provided on both sides of the bottom surface of the separating vehicle body, and a hydraulic lifting rod is fixedly installed in the groove of the bottom surface of the separating vehicle body. A wheel plate is fixedly installed at the lower output end of the hydraulic lifting rod, and rollers are provided at both ends of the bottom surface of the wheel plate. The rollers roll on the slide rail.

[0008] Preferably, a second radar transmitter is rotatably mounted in the middle of the separated vehicle body, with the radar generating and receiving structure of the second radar transmitter facing downwards. Motors are embedded in both sides of the separated vehicle body, and the output end of the motor is fixedly connected to the side rotating shaft of the second radar transmitter.

[0009] Preferably, hooks are fixedly installed on both sides of the top surface of the separation vehicle body, and two sets of winding rollers are fixedly installed on the side of the top surface of the detection vehicle body near the camera. One end of the winding roller is connected to a motor, and a rope is wound around the outer wall of the winding roller. The rope extends to the hooks and is connected to the hooks.

[0010] Preferably, the detection vehicle is equipped with an identification module and a signal transmission module, and the camera and the first radar transmitter are both electrically connected to the identification module inside the detection vehicle.

[0011] Preferably, pulleys are fixedly installed at the four corners of the bottom surface of the detection vehicle, and trolley handles are fixedly installed on both sides of the top surface of the detection vehicle, with the trolley handles extending diagonally upward toward the side away from the camera.

[0012] The beneficial effects of this utility model are: when the first radar transmitter detects dense underground pipelines or foreign objects such as rocks and roots directly below, the separation detection device is activated to separate from the detection vehicle and detect the area directly below the first radar transmitter from a distance at an angle, thereby bypassing foreign objects to detect underground road defects.
