Description
Technical field
The utility model belongs to well washing apparatus technical field, more particularly to a kind of motor-pumped well well washing apparatus.
Background technology
Motor-pumped well due to the presence of silt in well and sinks to the reasons such as shaft bottom, shadow after the completion of well-digging or in use
Ring the water quality of the water outlet of motor-pumped well.Well-flushing after revolution direct circulation mainly using extracting at present, due to washed device and cleaning side
Method limits, and well-flushing has following defect at present：First, due to cleaning when water pump location apart from sediment farther out, well casing is thicker, water
It is slow to flow upward velocity, bulky sediment or the big sediment of density are not easy to be extracted, and cause well-flushing not thorough；Second,
Motor-pumped well water yield is small, it is necessary to which intermittent cleaning, is not only cleaned not thoroughly, and the cleaning frequency is grown, and cleaning cost is high.
Utility model content
Problem to be solved in the utility model be just to provide it is a kind of cleaning thoroughly, the machine that cleaning performance is good, the cleaning frequency is short
Well well washing apparatus.
To solve the above problems, the technical scheme that uses of the utility model motor-pumped well well washing apparatus for：Including immersible pump and position
Sleeve pipe on the outside of immersible pump, the delivery port of the immersible pump connect with water outlet hollow drill, in the water outlet hollow drill
Outside is provided with reducer union, and described sleeve pipe is threadedly coupled with the reducer union, and described sleeve pipe lower end is connected with hollow into water
Drilling rod, it is described enter water hollow drill lower end be provided with drill bit, blasthole is provided with the drill bit, in the reducer union
On be provided with cable aperture, the cable of the immersible pump passes through described cable aperture, the cable aperture and the cable seal.
Its additional technical feature is：
The aperture of the blasthole enters the diameter of water hollow drill endoporus less than described in；
The aperture of the blasthole enters the 3/4 of water hollow drill endoporus for described in；
The water outlet hollow drill upper end is connected with sedimentation basin, and time connected with well head is provided with the sedimentation basin upper end
Water pipe.
Motor-pumped well well washing apparatus provided by the utility model compared with prior art, has advantages below：First, due to bag
Include immersible pump and the sleeve pipe on the outside of immersible pump, the delivery port of the immersible pump connects with water outlet hollow drill, it is described go out
Reducer union is provided with the outside of water hollow drill, described sleeve pipe is threadedly coupled with the reducer union, and described sleeve pipe lower end connects
Be connected into water hollow drill, it is described enter water hollow drill lower end be provided with drill bit, be provided with blasthole on the drill bit,
Be provided with cable aperture in the reducer union, the cable of the immersible pump passes through described cable aperture, the cable aperture with it is described
Cable seal, sediment upper surface is measured first apart from the distance between dynamic water level, is set according to measurement result into water core drill
The length of bar, make close to sediment upper surface, immersible pump to be located at below dynamic water level below drill bit, when immersible pump is opened, in sleeve pipe
Negative pressure is formed with entering in water hollow drill, the water with sediments such as silts enters water hollow drill, Ran Houjing from blasthole
Water outlet hollow drill is output to ground, and it is smaller to enter the diameter of bore of water hollow drill and water outlet hollow drill, current upward velocity
Greatly, and near with sediment distance, iron filings that the larger silt particle of density, the borehole wall come off etc. can be extracted, and cleaning is more thorough
Bottom, as sediment is reduced, its upper surface moves down, and can gradually increase the length of water outlet hollow drill as needed, diving
Pump and enter water hollow drill position and move down, make bit location all the time close to sediment；Second, because the aperture of the blasthole is small
In it is described enter water hollow drill endoporus diameter, the aperture of the blasthole be preferably it is described enter water hollow drill endoporus 3/4,
So, being more than or equal to the debris of water hollow drill internal diameter can not enter in drill pipe bore, avoid in water hollow drill
Hole plug；Third, because the water outlet hollow drill upper end is connected with sedimentation basin, it is provided with the sedimentation basin upper end and well head
The return pipe of connection, when well water yield is more, water can be expelled directly out, when water yield is smaller, the band of extraction
There is the water of the sediments such as silt after sedimentation basin precipitates, clear water is flowed back in well again, and cleaning need not be interrupted, and cleaning is more
Thoroughly.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model motor-pumped well well washing apparatus.
Embodiment
The structure and use principle of the utility model motor-pumped well well washing apparatus are done with reference to the accompanying drawings and detailed description
It is further described.
As shown in figure 1, the structural representation of the utility model motor-pumped well well washing apparatus, the utility model motor-pumped well well washing apparatus bag
Immersible pump 1 and the sleeve pipe 2 positioned at the outside of immersible pump 1 are included, the delivery port 3 of immersible pump 1 connects with water outlet hollow drill 4, in water outlet
The outside of hollow drill 4 is provided with reducer union 5, and sleeve pipe 2 is threadedly coupled with reducer union 5, and the lower end of sleeve pipe 2 is connected with empty into water
Heart drilling rod 6, drill bit 7 is provided with entering the lower end of water hollow drill 6, blasthole 8 is provided with drill bit 7, is set in reducer union 5
Cable aperture 12 is equipped with, the cable 9 of immersible pump 1 passes through cable aperture 12, and cable aperture 12 seals with cable 9.
Sediment upper surface is measured first apart from the distance between dynamic water level, is set according to measurement result into water hollow drill
6 length, the lower section of drill bit 7 is located at close to sediment upper surface, immersible pump 1 below dynamic water level, when immersible pump 1 is opened, covering
Pipe 2 enters water hollow drill 6 with formation negative pressure, the water with sediments such as silts in water hollow drill 6 is entered from blasthole, so
It is output to by water outlet hollow drill 4 outside well, it is smaller to enter the diameter of bore of water hollow drill 6 and water outlet hollow drill 4, on current
It is big to return speed, and it is near with sediment distance, and iron filings that the larger silt particle of density, the borehole wall come off etc. can be extracted, cleaning
It is more thorough.As sediment is reduced, its upper surface moves down, and can gradually increase the length of water outlet hollow drill 4 as needed
Degree, immersible pump 1 and enters the position of water hollow drill 6 and moves down, and makes the position of drill bit 7 all the time close to sediment.
The aperture of blasthole 8 is less than the diameter into the endoporus of water hollow drill 6, and the aperture of blasthole 8 is preferably hollow into water
The 3/4 of the endoporus of drilling rod 6, so, being more than or equal to the debris of water hollow drill internal diameter can not enter in drill pipe bore, avoid
Enter water hollow drill inner reversible cycle.
The upper end of water outlet hollow drill 4 is connected with sedimentation basin 10, and the backwater connected with well head is provided with the upper end of sedimentation basin 10
Pipe 11, when well water yield is more, water can be expelled directly out, when water yield is smaller, extraction carries silt etc.
The water of sediment is after the precipitation of sedimentation basin 10, and clear water is flowed back in well again, and cleaning need not be interrupted, and cleaning is more thorough.
The scope of protection of the utility model is not limited solely to above-described embodiment, as long as structure is washed with the utility model motor-pumped well
Well apparatus structure is identical, just falls the scope in the utility model protection.
