Water jet cleaning system for large-diameter deep well

Abstract

The invention discloses a water jet cleaning method for a large-diameter deep well, and belongs to the technical field of water jet cleaning application. The water jet cleaning method is characterized in that a cleaning manner is determined to be multi-spray-gun rotating water jet cleaning according to structural characteristics of the inner wall of the large-diameter deep well and the attributes of attachments on the well wall; multiple spray guns evenly distributed in the circumferential direction can rotate around the axis of the deep well under the drive of a rotating mechanism, and move in the axial direction of the deep well under the drive of a telescopic mechanism; the cleaning quality and the cleaning effect are observed through a video monitoring method; video monitoring cameras and a driving motor of the telescopic mechanism of a cleaning device are fixed on a worktable; the structural size of the worktable is designed according to the inner diameter of the deep well and a safety requirement; the structure of the worktable is designed according to a strength criterion; a high pressure water pipe in the well and a cable harness get in and out of the deep well via an extending and retracting mechanism; control buttons of the motor and the cameras are integrated in a portable control box; and a high pressure water pump and an electric hoist are independently controlled. The water jet cleaning method disclosed by the invention solves the problem that the large-diameter deep well cannot be automatically cleaned.

Description

technical field [0001] A water jet cleaning system for a large-diameter deep well belongs to the field of water jet cleaning application technology, and relates to the technology of cleaning residues on the inner wall of a large-diameter deep well, in particular to the technology of cleaning the residues on the inner wall of a large-diameter deep well. Background technique [0002] After each work of a large-diameter deep well, there will be many solid particles attached to the inner wall of the deep well. At present, the existing cleaning method is to adopt a manual cleaning method. Due to the large inner diameter and length of the deep well, there are deficiencies in manual cleaning, mainly because it takes a long time and the cleaning is not comprehensive. Water jet cleaning technology provides a technical basis for non-contact cleaning of large-diameter deep wells. However, there is no water jet cleaning equipment for large-diameter deep well cleaning at present. Con...
