Abstract

<P>PROBLEM TO BE SOLVED: To provide an in-well screen cleaning device whose body is hanged with a wire rope and is lowered down and lifted up in a well to substantially shorten a work time for more efficient cleaning work in the well. <P>SOLUTION: A motor fitted with a wire brush is hanged with a wire rope, and is inserted in a pipe. A motor shaft is fitted with the wire brush rotating eccentrically, which is pushed against a helical coil of a screen while being vibrated. As a result, the needle points of the brush prick scales to remove them. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

ボーリング井戸のスクリーン洗浄。 Screen cleaning of boring wells.

ボーリング井戸の取水部スクリーンの洗浄はボーリングマシーンを使用し、ボーリングロッドの先端にワイヤーブラシを取り付け回転させながら上下させスクリーンの目に詰まったスケールを除去する方法や高圧水を噴出してスケール除去している。 The boring well intake screen is cleaned using a boring machine, with a wire brush attached to the tip of the boring rod and rotating up and down to remove the scale clogged by the screen or by jetting high pressure water to remove the scale. ing.

本件は特にワイヤーを螺旋に形成したスクリーンの洗浄に着目している。
従来の洗浄方式ではボーリングロッドの脱着に費やされる時間が施工時間の大半を占め非能率である。又、ワイヤーブラシを回転させて洗浄する方法にあってはスクリーンの縦軸ロッドにワイヤーブラシの先端が当るために螺旋ワイヤーの内部まで洗浄できない。 This case pays particular attention to the cleaning of screens in which wires are spirally formed.
In the conventional cleaning method, the time spent for detaching the boring rod accounts for most of the construction time and is inefficient. Further, in the method of cleaning by rotating the wire brush, the tip of the wire brush hits the longitudinal axis rod of the screen, so that the inside of the spiral wire cannot be cleaned.

本案はワイヤーロープで洗浄機本体を吊り下げスクリーン部まで短時間で移動させる。 In this plan, the main body of the washing machine is suspended by a wire rope and moved to the screen in a short time.

ワイヤーブラシを回転させると装置本体が逆方向に回転し、ワイヤーロープ、及び電源コードの損傷を招く危険性があるのでワイヤーブラシを回転させること無く振動と、ブラシ先端の押付け効果でスケール除去を考えている。 If the wire brush is rotated, the main body of the device rotates in the opposite direction, which may cause damage to the wire rope and power cord. ing.

洗浄機本体をワイヤーロープで井戸内に吊降し、吊り上げが出来ることで作業時間が大幅に短縮される。 The washing machine body can be suspended in the well with a wire rope and lifted up, greatly reducing the work time.

ブラシ先端部を振動させながら押し付けることでスクリーンの細部までブラシの針先で突くようにブラシを作用させる事で洗浄効果が増大する。 By pressing the brush tip while vibrating the brush, the cleaning effect is increased by operating the brush so that the details of the screen poke with the tip of the brush.

Claims

In the well cleaning apparatus, the apparatus stabilizing wire brush 2 is attached to the upper and lower sides of the motor 1, the entire apparatus is vibrated by the vibration generating plate 3, the screen surface is cleaned, and the wire brush 4 is rotated eccentrically. As a result, the wire brush penetrates into the screen while vibrating, thereby improving the cleaning effect. In-well screen cleaning device characterized by a structure that can clean every corner of the screen without rotating the wire brush.
