Description
Technical field
The present invention relates to a kind of fire extinguishing medium irrigation device, especially a kind of fire extinguishing medium irrigation device that is applicable to coal mine ground drilling.
Background technology
Therefore there are large tracts of land coalfield fire in Xinjiang of China, Ningxia, and shallow embeddings such as Inner Mongol, Shanxi, northeast are hidden in coal seam pit mining and the strip mining transformation process and also had spontaneous combustion of coal seam, annual and coal amount loss reaches 10,000,000 tons.This class spontaneous combustion disaster burning things which may cause a fire disaster point is nearer apart from the face of land, generally adopts face of land construction drill, and firing-fighting mediums such as tube sealing perfusion yellow mud, gel, three-phase froth are administered then.In the filling process for the range of scatter that increases firing-fighting medium, prevent that firing-fighting medium from overflowing ground along boring, improve the fire extinguishing effect, need carry out sealing of hole to intrusion pipe in holing.At present, the method for sealing of employing has cement mortar or organic resin etc., and these class methods utilize intrusion pipe and the drill hole wall of the coagulability of cement mortar or organic resin in will holing to condense into an integral body to prevent overflowing of firing-fighting medium.There is following problem in this method in the practice of construction process: at first need during material sealing of holes such as (1) cement mortar or organic resin placing isolator apart from the position of boring certain depth, then cement injection or organic resin between boring and intrusion pipe.This method construction period is longer, and sealing of hole of normal condition needs 5～10min.In addition, the normal appearance causes the sealing of hole failure to need secondary hole sealing because of the isolator placement is bad.Moreover could pour into after also need waiting sealing material to solidify fully, incur loss through delay the improvement time.(2) produce a large amount of toxic and harmfuls in the coal spontaneous combustion process, during sealing of hole as quick blocking not being carried out in boring, toxic and harmful can be scurried to the face of land along boring, and harmful gas concentration is higher around the boring, and the people is under the high concentration pernicious gas environment very big to the body and mind injury for a long time.(3) fire extinguishing boring is after using cement mortar or organic resin sealing of hole, and because of cement mortar or organic resin condensation cure, the fire extinguishing medium irrigation pipe in causing holing can't reclaim, reuse; General construction drill is more in the spontaneous combustion of coal seam hazard management process of the shallow face of land, and this has just caused the great wasting of resources; (4) it is crucial observing regulation effect in the hazard management process, and the observation of regulation effect is got gas sample and temperature test analysis more usually by detaching pipelines in the drill-pouring governance process at present, and test process is loaded down with trivial details.Current, during administering, shallow face of land spontaneous combustion of coal seam do not have also that a kind of specially that fire extinguishing is administered at surface drilling is simple to operate, easy to use, reusable and be easy to the fire extinguishing medium irrigation device of collecting temperature and gas.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of simple in structurely, install, convenient disassembly, easy to use, reusable fire extinguishing medium irrigation device for coal mine ground drilling.
Technical scheme: fire extinguishing medium irrigation device for coal mine ground drilling of the present invention, it comprises the reducing steel pipe of L-shaped elbow, and the arrival end external diameter of reducing steel pipe is provided with the back-off groove, and the elbow corner of reducing steel pipe is provided with gas, temperature acquisition mouth; The straight length of reducing steel pipe is provided with location adjusting device; Location adjusting device is by the sleeve pipe that is located in the drill hole wall aperture, links to each other, is located at the I-shaped carriage outside the drill hole wall aperture with sleeve pipe, and the rotary handle that is located on the I-shaped carriage with reducing steel pipe threaded engagement constitutes; The bottom of reducing steel pipe is set with gum sleeve for being trumpet-shaped awl column casing on the external diameter of awl column casing, and the bottom of awl column casing is provided with the external screw thread outlet; The length sum of sleeve pipe and post rubber tube and the equal in length that is trumpet-shaped awl column casing.
The bottom of described sleeve pipe is provided with the back-up ring that blocks gum sleeve; Described gas, temperature acquisition mouth place are provided with by-pass valve control; The length of described gum sleeve is between 50-70cm.
Beneficial effect: the present invention is easy to use, only need fire extinguishing medium irrigation device is inserted boring, I-shaped carriage by location adjusting device is supported in the aperture with whole device for casting, adjust the Way in of device for casting, utilize the round tray of I-shaped carriage bottom to cover the fire extinguishing drilling orifice simultaneously, the interior toxic and harmful that prevents to hole is gushed out and is injured the constructor; The reducing steel pipe can be adjusted up and down, according to on-site actual situations, move down by rotating on the rotary handle drive reducing steel pipe integral, move by going up of awl cylinder position, utilizing the superior retractility of rubber tube to order about gum sleeve radially expands, make the outer matsurface of gum sleeve be close to drill hole wall, stop firing-fighting medium to overflow from the aperture, put the isolator complicated processes of cement injection or organic resin between boring and intrusion pipe again when having reduced material sealing of hole such as conventional cement mortar or organic resin earlier, can avoid simultaneously the phenomenon of a sealing of hole failure, wait for the time of solidifying after having saved cement injection or organic resin, the set-up time is short, the single borehole set-up time is no more than 2min.Fire extinguishing medium irrigation is opened temperature gas acquisition port valve temperature, gas in holing is gathered after a period of time, the examination perfusion effect need not detaching pipelines and carries out thermometric, gets gas.Pour into the back backward rotation rotary handle that finishes the reducing steel pipe is moved down, gum sleeve shrinks and restores to the original state, and the taking-up device for casting is used for next boring of putting out a fire to be used, and has realized the repeated use of device for casting, has saved financial cost.It is simple in structure, and is easy to use, and sealing of hole is quick, reusable, has practicality widely.
