Above-mentioned upper support ring is fixedly connected on the reducing step.
Be connected with tube connector between above-mentioned biscuit cutter and the stay pipe.
Contrast as can be known, prior art is only washed the stifled shale thing of nose end open by mediation boring and by current, but because the complicated component of charges in the old dead zone, materials such as coal cinder, coal slime, rubble, rock dust are arranged, along with old empty water flows in discharging water, current carry the shale thing and may compile the aperture again and stop up boring once more, and problem is manifested once again.The present invention has changed uncertainty and the low guaranteed of prior art in solving plug-hole, not to manage to dredge the shale thing, but propose to prevent that by pre-pipe laying the shale thing from entering the anti-blocking method of boring breakthroughly, bottom, goaf in drill tip is buried stay pipe in advance underground, and make the pre-pipe laying mouth of pipe exceed the shale layer, thereby a large amount of old empty water can freely be flowed down by the high-order aperture of reproducing, the shale thing generally can not enter boring simultaneously, reduce the possibility of the blocked water proof of holing, greatly increased the success rate of the unrestrained old empty water of single boring.
Compared with prior art, the following advantage of tool of the present invention:
1, utilize stay pipe to do dummy hole and penetrate the shale layer, stop in the unrestrained water that the shale logistics goes into boring, it is blocked fundamentally effectively to prevent to hole;
2, adopt this method to visit and need not repeatedly open-work in the engineering that discharges water or move the brill punching again, saved drilling project amount and engineering time, greatly improved operating efficiency, reduced engineering cost;
3, this equipment mechanism is simple, is convenient to processing and fabricating;
4, this installs easy to use simple and directly, is convenient to the Field Force and manipulates;

Embodiment 1
Referring to Fig. 1-Fig. 2, the anti-blocking aperture apparatus of a kind of unrestrained boring of old empty water, comprise the drill bit 1 that connects successively from top to bottom, stay pipe 2, the expanding mechanism that is provided with on pipe nipple 7 and the stay pipe 2, be provided with spilled water hole on drill bit 1 and the stay pipe 2 and pass through thread connection between the two, stay pipe 1 and pipe nipple 7 pass through splined, the tube wall internal diameter of stay pipe 2 is up big and down small, transition position is provided with the reducing step, described expanding mechanism comprises upper support ring 6, spring 4, lower support ring 9 and linkage, upper support ring 6 is connected with the two ends of spring 4 respectively with lower support ring 9, two free ends of two linkages are fixed in upper support ring 6 and lower support ring 9 respectively, two linkages are arranged in the vertical chute of offering on the tube wall 8, and upper support ring 6 is fixedly connected on the inwall of stay pipe 2.
In order to be provided with conveniently, upper support ring 6 is fixedly connected on the reducing step in the stay pipe 2.
The above drill bit is that outer rim is the form of structure of wedge shape, can change the gradient and the thickness of drill bit during use according to the boring stopping state, stops up section so that drill bit passes smoothly;
Using method of the present invention is: after spy discharges water boring whole hole withdraws from drilling rod, if the flow of old empty water is little in the boring, or the no old empty water outflow that is blocked of holing, can on common drilling rod, connect pipe nipple 7, the stay pipe 2 of packed into spring 4, support bar 5, upper support ring 6 and lower support ring 9 is installed on pipe nipple 7 then, on stay pipe 2, is connected drill bit 1 again.Because boring is to go up uphole, under the action of gravity of things such as drill bit 1 and stay pipe 2, spring 4 is subjected to force compresses, and support bar 5 closes up in chute 8.To be in this device that closes up state and put into hell, and owing to there is spline to connect between pipe nipple 7 and the stay pipe 2, can drives pipe nipple 7 after drilling rod rotates and rotate, pipe nipple 7 rotations can drive stay pipe 2 successively and drill bit 1 rotates.The normal upwards cleaning bottom of hole of beginning creeps into, because this device has drill bit 1, the boring idol has the hole of collapsing undergauge can not influence normally to creep into.Drill bit 1 enters the plug-hole place, strengthen pump amount pump pressure and wash away the plug-hole material, and suitably increase the rig rotating speed, but creeping into feeding rate will control well, sweep out the plug-hole thing up to drill bit 1 and enter the goaf, this moment, slush pump can pressure release, if termination of pumping and dismantle the water pigtail that is connected between drilling rod and the water pipe, have a large amount of old empty current in the drilling rod and come out, show that the goaf and the mouth of pipe that this device has entered foreign material such as being full of water, rubble, coal slime have been higher than the shale layer.Under the extruding of shale thing, stay pipe is swept along in the shale thing, and stop to creep into this moment, withdraw from drilling rod downwards, spring 3 extends at once and opens support bar 5, and stay pipe 2 is fixed in the old dead zone in the foreign material such as shale thing, makes that support bar is unlikely in discharging water afterwards falls into boring.After support bar opens, progressively drilling rod is withdrawed from boring, can begin formal unrestrained water, reduce to absolute altitude place, drill bit aperture up to the water level of old empty water is dredged.Also can continue unrestrained old empty water its water level reduced to minimum spilled water hole place absolute altitude if spilled water hole all stops up this moment, and the aperture of spilled water hole is little, has the shale thing to enter can be washed away by top-down flowing water in the pipe and can plug-hole.
This device is the disposable articles for use that make, and enters behind the goaf not recyclablely, though material has consumption, compared with manpower and materials and time cost that open-work or new punching are again consumed, overall benefit is far better.
Because the mixed and disorderly complexity of old dead zone deposit if the thickness of shale thing is bigger, can increase tube connector according to its thickness between drill bit 1 and stay pipe 2, this tube connector is that normal basket gets final product.
