Description

Automatic deep-well dredger

Automatically the deep-well dredger belongs to deep-well desilting equipment field.

The general life-span of present deep-well is all about 20 years, because the water source descends, the wall casing life-span, reasons such as geology variation, the easy silting in shaft bottom, accumulate over a long period, the water capacity of well can reduce gradually, until withered, again because wall casing is elongated, bring great difficulty to desilting, traditional deep-well desilting mode is to drill again at the aboveground rig that utilizes, and motor is aboveground, through power transmission shaft power is passed on the drill bit, the expense height, 200 yuan/meter on every drilling depth is installed complicated, time-consuming, generally about 30 days, dredging effect is poor, the power transmission shaft work destructible borehole wall, poor reliability.

The purpose of this utility model just is to overcome the deficiencies in the prior art, provide a kind of dredging effect good, do not destroy hole diameter, install very simple, reduction of erection time, the automatic deep-well dredger of raising the efficiency greatly.

The purpose of this utility model realizes in the following way:

This automatic deep-well dredger, comprising: carrier pipe is characterized in that: continuous double pump is set, and automatic controller, carrier pipe, main pump, inferior pump, agitator link to each other successively.

The purpose of this utility model also can realize in the following way:

Described automatic deep-well dredger, it is characterized in that: the double pump that links to each other is main submersible pump 3, inferior foul water pump 4, blowdown flexible pipe 1, blowdown steel pipe 2, submersible pump 3, foul water pump 4, agitator 5 link to each other successively, liquid level sensor 6 is by holding wire 13, and submersible pump 3, foul water pump 4 link to each other with automatic controller 10 by

lead

11,12.

Described automatic deep-well dredger is characterized in that: the well head top also is provided with hoisting device 9, clamping plate 7, and hoisting device 9 links to each other with clamping plate 7 by rope.

Described automatic deep-well dredger is characterized in that: liquid level sensor 6 is arranged on agitator 5 one sides.

Described automatic deep-well dredger is characterized in that: blowdown flexible pipe 1 links to each other with blowdown steel pipe 2 by elbow 8.

Described automatic deep-well dredger, it is characterized in that: automatic controller 10 also comprises: time relay LSJ1-LSJ3, auxiliary reclay KA, A.C. contactor KM1-KM5, knob SA1-SA3, liquid level display controller 11, liquid level sensor 6.

Automatic deep-well dredger of the present utility model, main inventive point is the double pump that adopts primary and secondary to link to each other, automatically control.Submersible pump 3 is as main pump, foul water pump 4 is as time pump, foul water pump 4 bottoms connect agitator 5, submersible pump 3 tops link to each other with blowdown flexible pipe 1 through blowdown steel pipe 2 elbows 8, and the well head top is provided with hoisting device 9, clamping plate 7, and hoisting device 9 links to each other with clamping plate 7 by rope, in order to realize automatic control, in agitator 5 one sides liquid level sensor 6 is set, liquid level sensor 6 links to each other with automatic controller 10 by holding wire 13 in deep-well mud.Because the particular design of automatic deep-well dredger, have dredging effect good, do not destroy the borehole wall, install very simple, greatly the reduction of erection time, advantage such as raise the efficiency, generally a bite deep-well is carried out desilting with automatic deep-well dredger of the present utility model, only needed to finish in two days, surplus reduction of erection time 20 reduce expenses 70%, and strengthened safety, reliability greatly in the sky.

Fig. 1 is the structural representation of automatic deep-well dredger of the present utility model;

Fig. 2 is the electric control theory figure of automatic deep-well dredger of the present utility model;

Fig. 1-2 is the most preferred embodiment of automatic deep-well dredger of the present utility model, among Fig. 1: 1 blowdown flexible pipe, 2 blowdown steel pipes, 3 submersible pumps, 4 sensors, 5 foul water pumps, 6 agitators, 7 hoisting devices, 8 elbows, 9 clamping plate, 10 automatic controllers, 11,12 leads, 13 holding wires, 14 liquid level display controllers.Among Fig. 2: M2 foul water pump of M1 master's submersible pump 3 motor 4 motor LSJ1-LSJ3 time relay KA auxiliary reclay KM1-KM5 A.C. contactor QF automatic air-break switch GDH-10 motor protector FR thermal relay QZB-40 self coupling reducing transformer S1, S2 liquid level sensor contact SA1 changeover switch SB1-SB3 knob FU1-FU2 fuse HL1-HL3 indicator lamp L1-L3 triple line A1-A2 ammeter.

Below in conjunction with accompanying drawing automatic deep-well dredger of the present utility model is described further: the automatic deep-well dredger of making a playscript with stage directions utility model as Fig. 1-2, the double pump that adopts primary and secondary to link to each other, the automatic controller of matching design, by agitator to mixing of precipitated mud and sand for many years, and be transported to main submersible pump, by main submersible pump mixture is proposed ground by carrier pipe, thereby finish deep-well desilting work.Automatic deep-well dredger of the present utility model, the abrading section all adopts the high duty alloy high-abrasive material, thereby strengthens service life of equipment, adopts the holding circuit that is provided with in liquid level sensor and the automatic controller, has avoided burning motor because of mud blocks.The course of work is as follows: after water pump installs, connect power supply, begin to go into the well by the requirement of normal submersible pump mounting process, behind the inferior foul water pump contact water surface, sensor obtains signal, at first changeover switch SA1 just being switched to changes, after liquid level sensor 6 has obtained the water signal, its contact S1, the S2 closure, contactor KM4 work, its main contacts closure, the inferior foul water pump work of just changing a job, agitator 5 begins to stir, and delays time after 5 minutes, presses the SB2 button, contactor KM2, KM3 work, its main contacts closure is connected auto-transformer QZB-40 operation, main motor for submerged pump M1 reduced-voltage starting, after time relay LSJ1 time-delay, disconnect contactor KM2, KM3 connects contactor KM1 work, its main contacts closure, sewage is carried in main submersible pump 3 normal operations, when run into mud feeding-up or when running into hard thing time foul water pump 4 motor M2 ammeter A2 electric currents indication rise, operating personnel should switch to backward position by hoisting device 9 rise water pumps with inferior foul water pump 4 changeover switch SA1 rapidly, recover normal until inferior foul water pump 4 motor M2 ammeter A2, continue slow drilling depth, so repeatedly, per 3 meters is a working cycles, strict controlled footage speed.Within 0.1 meter of the per minute, finish until desilting.Clamping plate 7 blowdown steel pipe 2 usefulness that fix are used during the slow drilling depth of hoisting device 9.Deep-well dredger of the present utility model has replaced the method that traditional trepan dredges a well, thereby significantly reduces the expense of deep-well desilting, can reduce expenses 70%.Sky surplus reduction of erection time 20.And safety, reliability have been strengthened greatly.
