Corrugated pipe structure and manufacturing method thereof

Abstract

The invention discloses a corrugated pipe structure and a manufacturing method thereof, and belongs to the field of corrugated pipes. The corrugated pipe structure comprises a pipe body, a plurality of treatment mechanisms, a pair of discharging and sucking mechanisms and a driving mechanism. The section of the pipe body is in a corrugated shape, the treatment mechanisms are installed at the concave positions of corrugations on the inner side of the pipe body, every two adjacent treatment mechanisms are in transmission, the treatment mechanisms are used for dredging blockages at the corrugated positions in the pipe body, and the driving mechanism drives the treatment mechanisms to swing to dredge the blockages on the inner wall of the pipe body. The pair of discharging and sucking mechanisms are symmetrically mounted on the outer side of the pipe body without corrugations relative to the center of the pipe body; the corrugated pipe is guided to be unfolded and contracted in a telescopic mode so as to compress and release transported objects; meanwhile, a translation force is converted into a rotation force, an arc-shaped gear ring in the corrugated pipe is rotated, a damage rod is driven in a meshing mode to damage the transported objects, the transported objects cannot be accumulated and blocked, and an evacuation force is formed.

Description

technical field [0001] The present invention relates to the field of bellows, more specifically, to a bellows structure and a manufacturing method thereof. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. Bellows are widely used in instruments and meters, and their main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end drives the poin...

AI Technical Summary

Problems solved by technology

Bellows are often combined with displacement sensors to form a pressure sensor whose output is electricity. Sometimes it is also used as an isolation element, and it can also be used to transport some materials, such as cement or mud. It is easy to cause the follow-up work to be impossible. The blockage is divided into blockage at the connection, blockage in the pipe and full blockage. General equipment cannot deal with the blockage at these two positions, and the treatment effect is not good enough.
