Video detection camera automatic centering device in pipe

Abstract

The invention discloses an automatic centering device mainly used for a camera to detect videos in a pipe. The video detection camera automatic centering device in the pipe keeps the camera in the central position of a pipeline all the time. The centering device is mainly composed of a central cylinder, sleeves, springs, supporting rods and the like, wherein the camera is arranged inside the central cylinder, the two sleeves are arranged on the central cylinder, one sleeve is axially fixed, the other sleeve can slide freely on a central cylinder body, a supporting part is composed of three sets of supporting rods, the supporting robs are distributed in a 120-degree circumference mode, each supporting rod is composed of a supporting rod body, a wheel, a pin, a clamp ring and corresponding parts, the two supporting rods respectively arranged on the two sleeves are crossed and are connected through the pins, each supporting rod is provided with a small hole to fix a spring, the springs play a role in guaranteeing that the three sets of supporting rods are contacted with the pipe wall all the time, and through the assembly of different positions of three motion secondary connecting holes in the middles of the supporting rods, three connecting schemes of the supporting rods are obtained, and therefore the centering device is applicable to work in a large pipe diameter range.

Description

technical field [0001] The invention relates to an adjustable automatic centering device of a camera mainly used for in-pipe video detection in the field of pipeline engineering. Background technique [0002] At present, domestic and foreign methods for detecting the inner wall of pipelines generally use camera video detection, and most of the cameras are directly installed on the pipeline robot, that is, mainly relying on the action carrier-pipeline robot, the existing pipeline video detection The camera does not solve the problem of being located in the center of the pipeline well, or ignores this aspect of the problem. The result is: the camera effect is not ideal, and the situation around the inside of the pipeline cannot be observed clearly at the same time. [0003] The present invention uses an automatic centering device to improve the position of the camera to achieve the best video detection effect. For circular pipelines, the best camera position should be at the ...

AI Technical Summary

Problems solved by technology

For circular pipelines, the best camera position should be at the center of the pipeline. General camera equipment is directly fixed on the traveling device, and the traveling device is limited by its own structure, so the camera cannot always be centered at the center of the pipeline. It greatly limits the visual range of the camera and affects the accurate judgment of the actual situation inside the pipeline.
