Description

Technical Field

[0001] This utility model relates to the field of ground penetrating radar technology, specifically a protective ground penetrating radar. Background Technology

[0002] Ground penetrating radar (GPR) is widely used in engineering geological exploration, road inspection, pipeline detection, and other fields. Most protective GPRs are manually handheld or fixedly mounted on the bottom of a vehicle for detection, which has problems such as low operation and detection efficiency and susceptibility to damage from external impacts. To improve detection accuracy and safety, some devices use robotic arms or guide rail mechanisms to move the radar. However, these structures are usually large, lack flexibility, and are inconvenient to install, disassemble, maintain, and replace. Therefore, they do not meet the current needs. In response, we propose a protective GPR. Utility Model Content
