Pipeline inner wall cleaning robot, control circuit and work method

Abstract

The invention discloses a pipeline inner wall cleaning robot, a control circuit and a work method. A motor and guide shafts are installed on a lower installation plate, the lower ends of the guide shafts are fixed to the lower installation plate, and a screw rod is in threaded connection with a nut. At least three radial telescopic assemblies are arranged on the nut in the circumferential direction. Small linear motors are symmetrically arranged on the upper side and the lower side of a large linear motor in each radial telescopic assembly, wherein a piston of the large linear motor is fixed to the position of the center of a rubber block, and a piston rod of each small linear motor is fixed to a radial moving block. Two sealing fixing devices are symmetrically arranged on the upper side and the lower side of a rolling brush, and a set of liquid passing holes are evenly distributed in the edge of a fixing disc in each sealing fixing device in the circumferential direction. The upper end of the screw rod is rotationally matched with the fixing disc of the lower fixing sealing device, and the upper ends of the guide shafts are fixed to the fixing disc; and a rolling brush motor is installed on the fixing disc of the upper sealing fixing device. According to the pipe inner wall cleaning robot, the control circuit and the work method, dirt on the inner wall of a pipeline can be cleanly and efficiently removed.

Description

technical field [0001] The invention belongs to the field of pipeline cleaning, and in particular relates to a pipeline inner wall cleaning robot, a control circuit and a working method. Background technique [0002] In the material or chemical industry, the cleanliness of the inner wall of the reaction medium conveying pipeline is an important part of determining the purity of the product, so it is often necessary to use cleaning agents for professional cleaning. At present, manual cleaning is the most common cleaning method and is commonly used in daily work. However, for some pipelines such as vertical installation, too long, too large or too small inner diameter, manual cleaning often has defects such as low cleanliness, low efficiency, and high labor costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipeline inner wall cleaning robot, which intends to clean the pipeline inner wall through the pipelin...
