Abstract
The utility model relates to an underground water exploring and draining hole drilling anti-spraying device, which belongs to the technical field of an underground water exploring and draining device in a mine. The underground water exploring and draining hole drilling anti-spraying device used at present easily generates large amplitude swing for a drill tool to cause a drill hole to deflect, rock or coal dust sundries easily block the drill hole and the control of the draining water quantity is bad so that the construction places are easy to submerge. The utility model is characterized in that a sealing cavity pipe 2, the inner part of which is provided with a baffle plate 3, is respectively connected with a fixed water draining part pipe 4 and a pressurizing cap 1 through screw threads and a water draining pipe 6 and a flange disc 5 are fixedly connected to the fixed water draining part pipe 4. The utility model has the advantages that the anti-spraying device solves the fixed problem so as to ensure that the drill tool can not generate swing in the drilling process; the utility model solves the problem that rock or coal dust sundries block the drill hole in the drilling process; the water draining pipe is additionally connected with a control gate valve so as to control the size of draining water quantity; the accident that construction place is submerged because the draining water quantity is greater than water draining quantity of a big pump is prevented.
Description
Technical field: the utility model relates to the mine and visits the jettison gear technical field with the down-hole, is that the boring blowout hookup that discharges water is visited in the down-hole more specifically.
Background technology: the coal mine test of using at present discharges water, and the easy swing that takes place by a relatively large margin makes the empty mark deflection of boring to blowout hookup to drilling tool, rock or ickings foreign material easily stop up boring, amount of water to be discharged control is not the fine job location of easily flooding, and the bad water outlet of sealing is many in the boring procedure.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is that the boring blowout hookup that discharges water is visited in a kind of down-hole of design.Its technical scheme is: the sealing lumen 2 that inside is provided with baffle plate 3 is connected and fixed sluicing portion pipe 4 respectively and adds gland 1 by screw thread, fixedly fixedly connected tapping pipe 6 of difference and flange 5 on the sluicing portion pipe 4.The advantage of this utility model is: this blowout hookup has solved a fixedly difficult problem well, thereby guarantee that drilling tool does not take place significantly to swing in drilling process, thereby avoid holing empty mark deflection, solve rock or the ickings foreign material in the drilling process and stopped up a boring difficult problem, tapping pipe adjunction control gate valve, the size of control amount of water to be discharged, to prevent that amount of water to be discharged from causing the job location accident of flooding greater than the displacement of big pump, be beneficial to rotating freely and the empty mark of stable boring of drilling rod, sealing reduces water outlet, empties the back and forms the annular seal space of storing airtight packing, and there is the gland of adding the outer end, the outer silk of outer snare is used to push packing to reach the purpose of airtight minimizing current after tightening.
Description of drawings: this accompanying drawing is the utility model structural representation.In the accompanying drawing: 1, add gland, 2, the sealing lumen, 3, baffle plate, 4, fixedly sluicing portion manages, 5, flange, 6, tapping pipe.
The specific embodiment: the sealing lumen 2 that inside is provided with baffle plate 3 is connected and fixed sluicing portion pipe 4 respectively and adds gland 1 by screw thread, fixedly fixedly connected tapping pipe 6 of difference and flange 5 on the sluicing portion pipe 4.Fixedly the flange 5 of sluicing portion pipe 4 and the butt joint of casing flange dish fix during concrete enforcement, drilling rod is penetrated connection sealing lumen 2, first-class drill bit, Butt sealing lumen 2 and fixing sluicing portion pipe 4, fill in packing, the first-class gland 1 that adds, starting rig normally creeps into, during soon saturating old man pools zone, tighten and add gland 1 and be used to push packing to reach the purpose of airtight minimizing current, open the drain valve on the tapping pipe 6, guarantee the quick outflow that current and coal are let out thing, can the controlled water flow size can in time get rid of clast that probing forms again and bit freezing not.
Claims (1)
1, the boring blowout hookup that discharges water is visited in the down-hole, it is characterized in that: the sealing lumen (2) that inside is provided with baffle plate (3) is connected and fixed sluicing portion pipe (4) respectively and adds gland (1) by screw thread, and fixedly sluicing portion pipe (4) is gone up fixedly connected tapping pipe (6) and flange (5) respectively.
