Portable buried pipe cable route detection system

The invention discloses a portable buried pipe cable route detection system. A hanging fish is fixedly mounted on the side board of an operation ship through a hanger; under the drive of a sonar electronic box, a transmitting transducer array in the hanging fish is used for transmitting low-frequency sound wave signals; a receiving transducer array in the hanging fish is used for receiving echo signals of a buried pipe cable, and the signals are input into the sonar electronic box; the sonar electronic box is used for transmitting, receiving, processing and transmitting low-frequency sound signals, and displaying the sound image of the image of the buried pipe cable and positioning the position of the pipe cable through low-frequency signals; due to the fact that the detection system is hung on the side board of the ship through the hanger, a large A frame or a gantry crane is not needed, and the detection system is lighter; and the detection system is directly arranged on the side board of the ship and does
