Pipe flow state monitoring device for drainage pipe network temperature and use method of pipe flow state monitoring device

The invention belongs to the technical field of monitoring, and particularly relates to a pipe flow state monitoring device for drainage pipe network temperature and a use method of the pipe flow state monitoring device. The top surface of the abutting disc is rotatably connected with an antenna, the top surface of the abutting disc is fixedly connected with a pair of damping sockets made of an elastic material, the lower surface of the antenna is covered with damping rubber, copper sheets are arranged between the lower surface of the antenna and the damping sockets, and the bottom surface of the abutting disc is fixedly connected with a connecting shell; the manhole cover is pried open, the probe is thrown into water, it is ensured that the conductivity probe has degrees, the antenna is parallel to the damping socket, then the antenna and the damping socket are inserted into an inspection well hole, then the antenna is rotated, the antenna is clamped above the well hole, the effect of quick hole-opening-free
