Description

A kind of simple well-washing device

Technical field

The utility model is related to a kind of well-washing device, specifically, being to be related to a kind of mining area into the special drifting well-flushing of hole sleeve Device.

Background technology

Have in mud, sediment and the borehole wall mudcake, rust and water-bearing layer hole when hydrology drilling and wellhole stifled Plug thing etc., in order to make that clear water outflow is flowed out in water-bearing layer, it usually needs cleaned.

At present, the method for well-flushing usually has following several：Clear water is pumped into former drilling pump, that is, after clear water changes slurry, then Well-flushing is continued cycling through, claims water flushing, stops clear water cycle, is carried up and down with piston is continuous in well casing, causes stress excitement, Borehole wall mudcake is destroyed, while dredges water-bearing layer hole, claims piston well-flushing；Piston well-flushing needs alternate repetition to carry out, before bailing test, First using centrifugal pump or air compressor, groundwater abstraction reaches water clearly and stablizes water outlet, then carry out bailing test, referred to as pumps Well-flushing and compressed air well-flushing are inhaled, in addition with carbon dioxide well-flushing, pickling well.

The above method is required for expending a large amount of water when cleaning, and cleans not thorough enough.

Utility model content

For the above, it is good that the purpose of this utility model is to provide a kind of practical convenient, cleaning performance, saves energy consumption Simple well-washing device.

For this purpose, technical solution provided by the utility model is such：

A kind of simple well-washing device, including hollow steel pipe, multiple through-holes are distributed in the even tube wall of the hollow steel pipe, each Through-hole penetrates a plurality of steel wire rope, and the steel cord ends are located on the outside of hollow steel pipe, and are distributed to form cleaning head into umbrella, The hollow steel pipe upper end is equipped with the internal thread being adapted with outer drill rod.

Further, above-mentioned a kind of simple well-washing device, it is logical that the steel wire rope crosses through arranging up and down for not homonymy Hole, the steel wire rope are in net distribution in hollow steel pipe.

Further, above-mentioned a kind of simple well-washing device, the through-hole are plum blossom hole.

Compared with prior art, technical solution provided by the utility model is rotating drive hollow steel pipe by outer drill rod Rotation, so as to drive cleaning head that can effectively clean borehole wall tamper in wall friction.Its through-hole uses plum blossom hole, is conducive to The stationary positioned of steel wire rope, steel wire rope cross through the through-hole arranged up and down of not homonymy, effectively prevent steel wire rope and are cleaning It is broken in the process, has reasonable in design, the production is simple and convenient, practical convenient, cleaning performance are good and can be according to being washed caliber The advantages that size changes well-washing device diameter, use scope is wide, can be used with popularity.

Description of the drawings

Fig. 1 is simple well-washing device dimensional structure diagram provided by the utility model.

Fig. 2 is that simple well-washing device provided by the utility model prolongs axis view.

Specific embodiment

With reference to embodiment and Figure of description, claims hereof is done it is further specifically It is bright, but do not form any restrictions to the utility model.

Embodiment 1

A kind of simple well-washing device provided by the utility model, refering to Fig. 1 and Fig. 2, including hollow steel pipe 1, the hollow steel Multiple through-holes 2 are distributed in the even tube wall of pipe 1, and each through-hole 2 penetrates a plurality of steel wire rope 3, and 3 end of steel wire rope is located at sky 1 outside of heart steel pipe, and be distributed to form cleaning head 5 into umbrella, using umbrella steel wire rope cleaning head, be conducive to increase cleaning by force Degree increases cleaning area.1 upper end of hollow steel pipe is equipped with the internal thread 4 being adapted with outer drill rod, is specifically needing In use, the external screw thread of the internal thread of hollow steel pipe 1 and outer drill rod is tightened.

Originally it washes in wall device, the steel wire rope 3 crosses through the through-hole 2 arranged up and down of not homonymy, and the steel wire rope 3 is in sky In net distribution in heart steel pipe 1, be conducive to increase the pulling force of steel wire rope 3, increase service life.

Originally it washes in wall device, the through-hole 2 is plum blossom hole, is conducive to the stationary positioned of steel wire rope 3, and cleaning performance is good.

Originally wall device is washed in use, the external screw thread of the internal thread of hollow steel pipe 1 and outer drill rod is tightened, and drilling rod rotation drives Hollow steel pipe rotates, so as to drive cleaning head that can effectively clean borehole wall tamper in wall friction.

While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case of the principle and spirit for not departing from the utility model, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
