EXPLORATION DEVICE FOR DETECTING LOCATION OF SEWER FACILITY

摘要

An exploration device for detecting the location of a sewage facility comprises: a CCTV vehicle which moves in a sewage pipe; a camera unit which is installed in the CCTV vehicle and photographs the front and top of the sewage pipe to identify the direction of the sewage pipe and the location of a connection pipe connected to the sewage pipe; a telescopic cylinder which is installed in the CCTV vehicle; a fluid supply unit which transfers the end of the telescopic cylinder to the top of the connection pipe by driving the telescopic cylinder; a magnetic field generating unit which is arranged on the end of the telescopic cylinder and provides a magnetic field to the inside of the connection pipe; and a movable magnetic field detector which identifies the location of the connection pipe connected to the sewage pipe by detecting the magnetic field on the ground.
