An anti-sedimentation drainage pipe

Abstract

The invention discloses an anti-deposit drain pipe which comprises a pipe body (1) circular in the drift diameter direction and two ball bearings. Outer rings (2) of the bearings are connected with the inner wall faces of the two ends of the pipe body (1) respectively. Inner rings (3) of the two bearings are connected obliquely through four triangular prisms (4). Water flow must impact on all the side faces of the triangular prisms (4) when passing through the pipe body (1) in parallel so as to push all the triangular prisms (4) and the inner rings (3) of the bearings to rotate in the pipe body (1), so a stirrer is formed, water flow containing rain dirt passes through the pipe body (1) in a rotating and stirring state, and thus the deposit of dirt on the inner wall of the pipe body (1) is avoided or reduced. If necessary, the pipe body (1) can be dredged to maintain the stirring function of the pipe body (1) by manually rotating the triangular prisms (4) at open caisson facility adjacent to the pipe body (1).

Description

technical field [0001] The invention belongs to drainage pipes, and more specifically relates to an anti-silting drainage pipe. Background technique [0002] An existing drainage pipe buried horizontally in the ground has been used for a long time, and the lower inner wall of the pipe body will be deposited due to mud settlement, so that the diameter of the pipe body becomes smaller and smaller. Because the drainage pipe is often buried underground, it is difficult to replace or Difficult to clear. Therefore, it is of great significance to provide an anti-silting drain pipe. Contents of the invention [0003] It is an object of the present invention to provide a drainpipe that is anti-silting. [0004] An anti-silting drainage pipe of the present invention comprises a pipe body with a circular diameter, two ball bearings, the outer rings of each bearing are respectively connected to the inner wall surfaces at both ends of the pipe body, and the two bearings The inner ri...
