Underground pipeline detection device suitable for outdoor complex environment

The utility model relates to the technical field of detection devices, in particular to an underground pipeline detection device suitable for an outdoor complex environment, which comprises a receiver, a protection pad is fixedly connected to the outer side of the receiver, a damping plate is fixedly connected to the outer side of the protection pad, and a first spring is fixedly connected to the top end of the damping plate. The top end of the first spring is fixedly connected with a fixing frame, the outer side of the fixing frame is fixedly connected with a supporting plate, and the receiver is slidably connected with the supporting plate. Through the arrangement of a damping plate, a damping damper, the first spring, a second spring and a pulley, due to the fact that underground pipeline detection is carried out outdoors, the road environment is complex; when the receiver passes through the uneven road, the receiver can jolt severely, and the device has a damping effect on the receiver and avoids violent
