Abstract
The utility model relates to a coalbed gas takes out and adopts rotation type water conservancy slot nozzle, including the pole of intaking, the bottom shutoff of the pole of intaking sets up the delivery port on the wall, the outside rotatable rotatory nozzle that is connected with of the pole of intaking, the inside delivery port that corresponds of rotatory nozzle is equipped with annular water cavity, and water cavity circumference is equipped with a plurality of spouts, the spout sets and to transmit spout spun water jet for rotatory nozzle and to promote the at the uniform velocity rotatory guide plate of rotatory nozzle, and this nozzle has changed the tradition and has leaned on the pole rotation of intaking and carry out the operation of coal seam water conservancy slot, utilizes the counter -force of water jet to promote rotatory nozzle steady rotation, and avoided promptly the intaking pole and a large amount of energy of the direct friction consumption in coal seam have improved efficiency again, have reduced intensity of labour.
Description
Technical field
The utility model relates to a kind of hydraulic slotted liner technique nozzle, specifically the rotary hydraulic slotted liner technique nozzle of a kind of coal bed gas extraction.
Background technology
Coal bed gas extraction is the basic prophylactico-therapeutic measures avoiding coal mine gas disaster to occur, hydraulic turbulence forms the flat slot of certain space by water jet in inside, coal seam, make coal body stress relaxation, release after slot, destroy, break, UNICOM crack is formed near slot, with at double or ten permeability improving coal seam several fold, thus effectively improve gas migration speed, then extraction is carried out to coal-bed gas, make gassy seam become present low gas or without gassy seam, fundamentally avoid Gas Disaster to occur.
A gap to be cut in coal body inside, the shower nozzle of hydraulic slotted liner technique will be allowed to realize rotating.At present conventional method is when carrying out hydraulic slotted liner technique in the borehole, rotates the rotation that water inlet bar realizes shower nozzle, water inlet bar and coal body direct friction when this mode causes rotation, and its rotating speed is not easy control, troublesome poeration and wasting time and energy.
Utility model content
For above-mentioned prior art Problems existing, the utility model proposes a kind of rotary hydraulic slotted liner technique nozzle, adopt the water jet principle of reaction, improving water bar rotating manner is swivel nozzle mode, not only revolves speed during operation evenly, and efficiently, easy and simple to handle.
To achieve these goals, the technical solution adopted in the utility model is: a kind of rotary hydraulic slotted liner technique nozzle, comprises into water bar, and the bottom shutoff of water inlet bar, bar wall sets out the mouth of a river; Described water inlet bar outer rotatable be connected with swivel nozzle, the inner corresponding delivery port of swivel nozzle is provided with annular water chamber, and water cavity is circumferentially with multiple spout; Described spout is equipped and the water jet that spout sprays can be passed to swivel nozzle and promote the deflector that swivel nozzle at the uniform velocity rotates.
Described deflector is arcuate structure, and its one end is fixed on the side of spout, and the other end is free end, tilt to extend to the opposite side of spout, and the water conservancy diversion direction of each deflector is contrary with the rotation direction of swivel nozzle.
The width of described deflector is not less than the diameter of spout.
Described delivery port at least arranges two, and circumference is distributed on on water bar bar wall.
Described spout at least arranges two.
The bore of described spout is less than the bore of delivery port.
The end of described water inlet bar is by nut shutoff, and nut is threaded with water inlet bar, and the diameter of nut is greater than the diameter of swivel nozzle.
Described water inlet bar is provided with alignment pin, and swivel nozzle is limited between alignment pin and nut.
The beneficial effects of the utility model: this nozzle changes tradition and rotates the mode of operation of carrying out coal seam hydraulic slotted liner technique by water inlet bar, the counter-force of water jet is utilized to promote swivel nozzle uniform rotation, namely avoid and consume mass energy into water bar and coal seam direct friction, turn improve efficiency, reduce labour intensity.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of rotary hydraulic slotted liner technique nozzle, comprises into water bar 1, and the bottom shutoff of water inlet bar 1, bar wall sets out the mouth of a river 8; Described water inlet bar 1 outer rotatable be connected with swivel nozzle 5, the inner corresponding delivery port 8 of swivel nozzle 5 is provided with annular water chamber 3, and water cavity is circumferentially with multiple spout 7; Described spout 7 is equipped and the water jet that spout 7 sprays can be passed to swivel nozzle 5 and promote the deflector 4 that swivel nozzle 5 at the uniform velocity rotates.
Described deflector 4 is arcuate structure, and its one end is fixed on the side of spout 7, and the other end is free end, tilt to extend to the opposite side of spout 7, and the water conservancy diversion direction of each deflector 4 is contrary with the rotation direction of swivel nozzle 5.
The width of described deflector 4 is not less than the diameter of spout 7.
Described delivery port 8 at least arranges two, and circumference is distributed on on water bar 1 bar wall.
Described spout 7 at least arranges two.
The bore of described spout 7 is less than the bore of delivery port 8.
The end of described water inlet bar 1 is by nut 6 shutoff, and nut 6 is threaded with water inlet bar 1, and the diameter of nut 6 is greater than the diameter of swivel nozzle 5.
Described water inlet bar 1 is provided with alignment pin 2, and swivel nozzle 5 is limited between alignment pin 2 and nut 6.
During use, current enter annular water chamber 3 by delivery port 8 by water inlet bar 1, then sprayed by spout 7, current are through deflector 4 water conservancy diversion, tangential direction along swivel nozzle 5 sprays, and produce the uniform rotation of reaction force promotion swivel nozzle 5, and arranging of nut 6 can prevent swivel nozzle 5 from touching drill hole wall, ensures that it runs well.Only need that this nozzle is replaced traditional structure nozzle can use, easy to operate, time saving and energy saving.
