Robot for detecting drainage pipeline video

Abstract

The invention discloses a robot for detecting drainage pipeline video, which belongs to mechanical equipment for a pipeline. The integral structure of the robot comprises an image pickup system, a lens control system, a body driving mechanism, a software control and data transmission system and an illumination device. The members have the following relationships that: the driving system loads other systems to crawl in the pipeline, the lens control system is used for adjusting the position and angle of the image pickup system, the image pickup system acquires internal information of the illuminated pipeline, and finally the information is output to a computer screen through the data transmission system. The robot has small size, and is suitable for observing the environment in a sewer with the pipe diameter of 300 to 800 millimeters and the filling degree of no more than 50 percent; the gravity center of the body is low, so the robot is not easy to turn to one side; and the integral weight is lighter so as to facilitate field operation of workers.

Description

technical field [0001] The invention relates to an instrument for pipelines, in particular to a video inspection robot for drainage pipelines. Background technique [0002] Pipeline inspection robot is an opto-mechanical-electrical integration system that can automatically walk along the inside of the pipeline, carry one or more sensors and operating machinery, and perform a series of pipeline operations under the remote operation of the operator or the automatic control of the computer. Drainage pipeline inspection robots can be used for pipe network acceptance, defect detection, dredging, repairing and other work. [0003] A complete pipeline detection robot system should be composed of a mobile carrier (crawler), a pipeline internal environment recognition and detection system, a signal transmission and power transmission system, and a control system. A general video inspection robot for drainage pipes should meet the following conditions: camera connected to the compute...

AI Technical Summary

Problems solved by technology

Existing drainage pipeline robots require the pipeline to be dry or with less water during the operation process. If necessary, the upstream sewage must be blocked to prevent the fuselage from being submerged in sewage during detection and unable to work.

[0006] For the pipelines in southern regions or some industrial areas in China, the drainage pipelines are in a state of high filling degree for a long time, the sewage in the drainage pipelines is not easy to drain away, and it is not suitable for blocking the upstream water, which brings problems to the work of the pipeline inspection robot.

In addition, the existing domestic robots are relatively heavy, which brings inconvenience to the staff during the operation; at the same time, it is prone to rollover when walking in a pipeline with a small diameter
