Mud increases the permeability around screen pipe, well is made to reach due stable water yield.
Currently, there are two types of methods for piston well-flushing, one is methods drilling rod lifting and push piston, and another kind is wirerope
The method for lifting piston, existing piston well washing apparatus major defect are, different according to the diameter of drilling well mouth, need replacing difference
The piston apparatus of diameter, so that piston well-flushing working efficiency is low.
Utility model content
In order to overcome the shortcomings of that existing hydrogeological well washing apparatus, the utility model provide a kind of adaptive hole of gravity type
Diameter well-flushing piston apparatus.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the adaptive aperture well-flushing piston dress of gravity type
It sets, including, cylinder and capsule, the cylinder are in hollow cylindrical shape, and the top of cylinder is equipped with nozzle, the side of cylinder
It is symmetrically arranged with two vertical guiding gutters, the nozzle of cylinder is equipped with cover board, and the cover board is fixedly connected with that there are two settings to exist
The intracorporal arc block water plate of cylinder, the intracorporal two arc block water plates of the cylinder are bonded two guiding gutters；The arc water blocking
On piece is equipped with the strip projected parts for the cross spacing when guiding gutter moves up and down, and the bottom surface of the cylinder is equipped with bottom valve, institute
Suspension hook is additionally provided at the top of the cylinder stated.
The capsule is connected by two guiding gutters with inner barrel around the lateral surface for being connected to cylinder, capsule；
The top of capsule is equipped with vent valve.
Two arc block water plates can move up and down in cylinder along guiding gutter.
The adaptive aperture well-flushing piston apparatus of this gravity type is put into well, after the present apparatus is submerged under water, cylinder bottom surface
Bottom valve is washed open by hydraulic pressure, and water and mud enter cylinder, and cover board moves up the cylinder opened at the top of cylinder in cylinder under the action of hydraulic pressure
Mouthful, meanwhile, cover board drives two arc block water plates to move up in cylinder along guiding gutter；Arc block water plate opens guiding gutter,
So that capsule is connected by the guiding gutter of two cylinders with inner barrel；Water and mud enter capsule by cylinder and are allowed to swollen
It is swollen；After capsule is constantly expanded into the size for adapting to hole wall, this piston apparatus stops downlink, the bottom valve of the cover board of nozzle and bottom according to
It is slowly closed by gravity, cover board, which moves down, drives two arc block water plates to move down in cylinder along guiding gutter；Arc gear
Water piece closes guiding gutter, so that capsule has been filled with water and mud, keeps being expanded into the volume after the size for adapting to hole wall, this piston
When device uplink, bottom valve is closed, and arc block water plate closes guiding gutter, and the water and mud for being filled with capsule will not be discharged, and realizes sealing
Effect.
The utility model has the beneficial effect that the present apparatus may expand adaptive pore size, is suitable for different pore size
Drilling well-flushing, the liquid for being trapped in capsule increases the volume of piston body, and liquid is sealed by arc block water plate in capsule body
Closing will not be discharged, and ensure that the leakproofness of piston apparatus, and well-flushing efficiency can be greatly improved, and water and mud are filled in cylinder and capsule
Inside, piston apparatus uplink, since capsule expansion before has been adapted to pore size, so sealing effect is preferable, piston apparatus
Uplink generates negative pressure, forms pressure difference, destroys borehole wall mudcake, enters underground water in well, and carry out the fine particles such as landwaste,
The thick liquid on piston apparatus top flows out well head during lifting, during lifting repeatedly, sticky mud quilt in well
Underground water displacement, easy lifting auxiliary and power device, which is arranged, by well head can carry out piston well-flushing operation, can open at any time
Well-flushing work is opened up, dramatically saves manpower, and reduce well-flushing cost.
