The invention provides a pipeline pressure detection device. The pipeline pressure detection device comprises an outer ring sleeve part, an inner ring sleeve part, a first magnet and a second magnet, wherein the outer ring sleeve part is arranged on the outer wall of the pipe body, the first magnet is fixedly connected to the outer ring sleeve part, the inner ring sleeve part is arranged on the inner wall of the pipe body, and the second magnet is fixedly connected to the inner ring sleeve part. The outer ring sleeve part moves on the pipe body, so that the first magnet fixedly connected to the outer ring sleeve part drives the second magnet and the inner ring sleeve part fixedly connected with the second magnet to move in the pipe body, wherein the inner ring sleeve part comprises an inner ring elastic sleeve and a fixing ring, and the fixing ring is arranged on the inner wall of the inner ring elastic sleeve in a sleeving mode. A plurality of pressure switches are arranged on the fixing ring, indicating lam
