Underwater robot driving roller

Abstract

The invention discloses an underwater robot driving roller. The underwater robot driving roller comprises an inner barrel and an outer barrel which sleeves the inner barrel in a rotating mode, and a motor is fixedly arranged in the inner barrel; a first flange, a motor cover, a first connecting piece and a second connecting piece are coaxially arranged in the axial direction of an output shaft ofthe motor in sequence; the motor cover comprises a disc body and a first column-shaped body which is arranged in the center of the disc body and is integrally formed with the disc body; a first through hole is formed in the center of the first column-shaped body in the axial direction, and a second column-shaped body is rotationally inserted into the first through hole; and a second through hole and a third through hole are formed in the first connecting piece in the axial direction, the output shaft of the motor is inserted into the second through hole, and the output shaft of the motor is fixedly connected with the first connecting piece through a key. The output shaft of the motor is directly connected with the first connecting piece through the key, the outer peripheral surface of thefirst connecting piece is fixedly connected with the outer barrel, the motor is fixedly connected with the inner barrel, then the motor drives the first connecting piece to rotate so as to drive the outer barrel to rotate, the power transmission efficiency is high, the energy loss is small, and the outer barrel is guaranteed to rotate normally.

Description

technical field [0001] The invention relates to an underwater robot driving drum. 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 the size of the pipeline and the harsh environment, resulting in high work intensity and low work efficiency. The problem currently arises with pipeline bots. [0003] One of the key technologies of the pipeline robot is that it must have good waterproof performance. The existing patent discloses a driving roller, application number 201710896...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a driving drum for an underwater robot, which solves the technical problem that the driving drum in the prior art uses a permanent magnet motor and a permanent magnet coupling for power transmission, and the power transmission efficiency is too low, resulting in the drum not rotating normally
