Upward-floating and downward-diving driving mechanism of all-water pipeline robot

Abstract

The invention discloses an upward-floating and downward-diving driving mechanism of an all-water pipeline robot. The mechanism comprises a steering engine and a shell, wherein the steering engine is fixed in the shell in a sealed mode, an output shaft of the steering engine extends out of the shell and is connected with a pipeline robot body through a first connecting piece, and the end, away fromthe output shaft of the steering engine, of the shell is rotationally connected with the pipeline robot body through a second connecting piece. According to the mechanism, the steering engine is arranged, the pipeline robot body is rotationally connected with the steering engine, the steering engine is arranged in the pipeline robot body, and the pipeline robot body is driven to rotate within a set range through rotation of the steering engine, so that the motion posture of the all-water pipeline robot is changed, and the robot can perform upward floating and downward diving in an all-water pipeline so as to carry out omnibearing detection on the pipeline; besides, the steering engine is fixedly connected with other components, so that the weight of the driving mechanism is increased, andit is guaranteed that the pipeline robot body deflects on the premise that the posture of the driving mechanism cannot be changed; and the driving mechanism is simple in structure, easy to machine and assemble, easy to control and high in control precision.

Description

technical field [0001] The invention belongs to the field of pipeline robots, and in particular relates to a floating and diving driving mechanism for a full-water pipeline robot. Background technique [0002] The environment of municipal pipelines is very harsh, and after long-term use, it is prone to corrosion, fatigue damage, or potential internal defects of the pipeline to develop into damage and cause leakage accidents, etc., especially for water pipelines, which are also prone to blockage and other accidents. Therefore, the in-pipe detection and desilting of pipelines is a very important practical project. At present, most of the in-pipe detection and decontamination are performed manually, which is limited by factors such as pipeline size and harsh environment, resulting in high work intensity and low work efficiency. [0003] Based on this problem, pipeline robots have appeared at present. The pipeline robot researched by the applicant in the early stage is suitable...
