Self-adaptive variable-diameter cleaning system in pipe

Abstract

The invention discloses a self-adaptive variable-diameter cleaning system in a pipe. The self-adaptive variable-diameter cleaning system comprises a shaft rod and a plurality of sets of mechanical arms, wherein one end of the shaft rod is connected with a rotary driving device, a bearing platform is arranged at the other end of the shaft rod, a fixed seat and a sliding seat are sequentially arranged on the shaft rod in the direction from the rotary driving device to the bearing platform, the fixed seat is fixedly connected with the shaft rod, the sliding seat is connected to the shaft rod in asliding mode and can move along the shaft rod, a compression spring is arranged between the sliding seat and the bearing platform, and the compression spring is arranged on the shaft rod in a sleeving mode; and the mechanical arms are arranged on the shaft rod in a surrounding mode, each mechanical arm comprises a cleaning head, a supporting rod and an adjusting rod, one end of each supporting rod is hinged to the corresponding cleaning head, the other end of each supporting rod is hinged to the fixed seat, one end of each adjusting rod is hinged to the middle of the corresponding supportingrod, and the other end of each adjusting rod is hinged to the sliding seat.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to an adaptive diameter-variable cleaning system in a pipeline. Background technique [0002] The diameter of the inner wall of the current large-scale cable casing generally changes within Φ270-Φ600, and its inner wall surface is a Φ270-Φ600 inner cone surface or a combination of multiple discontinuous inner cone surfaces. When installing the bushing, the inner wall of the bushing needs to be cleaned to ensure that the inner wall is clean and free of impurities such as stains, dust, and tiny particles, so as to ensure insulation safety under high voltage and ultra-high voltage. Conventional cleaning equipment is difficult to adapt to its pipe diameter. Therefore, at present, the cleaning of large-scale cable terminal casings still adopts manual cleaning, which is difficult and inefficient. In order to prevent dirt from being carried into the pipeline or cause secondary p...

Conventional cleaning equipment is difficult to adapt to its pipe diameter

Therefore, at present, the cleaning of large-scale cable terminal casings still adopts manual cleaning, which is difficult and inefficient. In order to prevent dirt from being carried into the pipeline or cause secondary pollution, it is necessary to wrap the whole body with plastic wrap before entering the narrow and long pipeline. cleaning inside, the working space is limited and it is impossible to do a comprehensive cleaning
