Abstract
A portable blast hole drainage device comprises a drainage pipe and an air pipe, wherein an air bag is arranged outside the pipe wall of the upper part of the drainage pipe in a sealing mode and is in contact with the inner wall of a blast hole; one end of the air pipe is connected with the air compression device, the other end of the air pipe is provided with a first air branch pipe and a second air branch pipe, and the first air branch pipe and the second air branch pipe are respectively provided with a first valve and a second valve; the first air branch pipe is communicated with the inner cavity of the air bag, and the second air branch pipe penetrates through the air bag. When the utility model drains water, the drain pipe is extended into the blast hole; opening the first valve and closing the second valve; the air bag is inflated through the first air branch pipe, the air bag is in complete contact with the inner wall of the blast hole, so that the bottom of the blast hole and the air bag form a closed cavity, the first valve is closed, the second valve is opened, the pressure in the closed cavity formed by the bottom of the blast hole and the air bag is continuously increased, and the water in the blast hole is continuously extruded from the water drainage pipe. The utility model is of an integral structure, convenient carrying, installation and disassembly.
Description
Technical field
A kind of the utility model category opencut guarded drainage technical field, and in particular to portable Shothole pumping gear.
Background technology
The easy ponding of blasthole and drainage of explosive hole difficulty are the hard nut to cracks of always puzzlement air bench blasting work.Blasthole
Ponding will make non-watertight explosive fail, phenomenon of miss-firing；Since water-proof explosive is mostly oil, density is relatively low, blasthole ponding
Water-proof explosive can be made to float, design shot depth is not achieved in the practical powder charge of blasthole, and then influences demolition effect.Existing blasthole row
Water installations such as " the drainage of explosive hole method and device of more ecads（Wuhan University of Technology, 104654937A）", a kind of " mine blasthole
Drainage equipment（Benxi Steel Plate Co., Ltd., 205533055U）", a kind of " deep blasting hole water drainage device in vapour-pressure type（China's meter
Measure university, 206092061U）", a kind of " efficient drainage arrangement of blasthole（：Guizhou University, 206556521U）" etc. all have knot
The features such as structure is complicated, site requirement is stringent, in view of step demolition of strip mines region have raw material and power supply is poor, explosion when
Between require the features such as nervous, work site environment is severe, above-mentioned several mine drainage of explosive hole equipment in practical applications often by
In complicated, installing and dismounting difficulty, subsequent blasting work cannot be influenced in time by the ponding discharge in blasthole.
Utility model content
The utility model provides a kind of portable Shothole pumping gear, and the ponding in blasthole can be discharged rapidly：
The utility model is achieved through the following technical solutions：
A kind of portable Shothole pumping gear, including drainpipe and tracheae, the drainpipe top tube wall external seal are set
It is equipped with gas bag, gas bag is contacted with blasthole inner wall sealing；Described tracheae one end is connect with air compression plant, and the tracheae other end is equipped with
It is respectively equipped with the first valve and second in first air branch pipe and the second air branch pipe, the first air branch pipe and the second air branch pipe
Valve；First air branch pipe is connected to gas bag inner cavity, and the second air branch pipe runs through gas bag.
The water inlet of the drainpipe is equipped with strainer.
The beneficial effects of the utility model：The utility model stretches into drainpipe in blasthole in draining；Open the first valve
Door closes the second valve；Give gas bag inflation by the first air branch pipe, the full contact of gas bag and blasthole inner wall make blasthole bottom with
Gas bag forms a closed cavity, closes first the second valve of valve opening, as blasthole bottom and gas bag formation one are close
The pressure in cavity closed constantly increases, and the water in blasthole is constantly extruded from drainpipe.The utility model is overall structure, just
In carrying, installation and dismounting；Drainage power is compressed air, with outdoor blasthole perforator as same power resources, is not necessarily to
External impetus；When mine drainage of explosive hole task is little, this practicality can also serve as mine proper drainage pipe and use, can with mine its
The unified storage of his drainage pipeline, transport.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1, drainpipe；2, gas bag；3, strainer；4, tracheae；5, the first valve；6, the second valve；7, water outlet；8、
Water inlet；9, air compression plant；10, the first air branch pipe；11, the second air branch pipe.
Specific implementation mode
Referring to Fig. 1, a kind of portable Shothole pumping gear, including drainpipe 1 and tracheae 4,1 upper tube of the drainpipe
Wall external seal is provided with gas bag 2, and gas bag 2 is contacted with blasthole inner wall sealing；4 one end of the tracheae is connect with air compression plant 9,
4 other end of tracheae is equipped with the first air branch pipe 10 and the second air branch pipe 11, the first air branch pipe 10 and the second air branch pipe 11
On be respectively equipped with the first valve 5 and the second valve 6；First air branch pipe 10 is connected to 2 inner cavity of gas bag, the second air branch pipe
11 run through gas bag 2.
It is equipped with strainer 3 at the water inlet 8 of the drainpipe 1, prevents impurities in water from entering drainpipe and causes water-pipe blockage.
Drainpipe 1 is establishment rubber material, and 1 outer diameter of drainpipe is the 80% of ponding blasthole diameter；Wall thickness 10mm；Length 8m；
Fixing water inlet 8 in drainpipe 1 has filter bowl（3）.Gas bag 2 is attached to away from the 1m of drainpipe top；2 material of gas bag is butyl rubber
Glue, wall thickness 10mm are not less than 250mm full of external profile diameter after gas；In first air branch pipe 10 and the second air branch pipe 11 respectively
Equipped with the first valve 5 and the second valve 6；First air branch pipe 10 is connected to 2 inner cavity of gas bag, and the second air branch pipe 11 runs through
Gas bag 2 is not communicated with 2 inner cavity of gas bag.
Specific work process：In draining, the utility model is stretched into blasthole, 1 water inlet 8 of drainpipe is in lower outlet
7 upper；It opens the first valve 5 and closes the second valve 6；It is inflated to gas bag 2 by the first air branch pipe 10, in gas bag 2 and blasthole
Wall completely attaches to and then blasthole bottom is made to form a closed cavity with gas bag 2, closes the first valve 5 and opens the second valve 6,
Air compression plant 9 is constantly ventilated in the closed cavity；As a closed cavity is formed on blasthole bottom and gas bag
Interior pressure constantly increases, and the water in blasthole is constantly extruded from drainpipe, after there is no water from the discharge of drainpipe 1, closes
Second valve 6 disconnects tracheae 4 and is connect with air compression plant 9, after opening valve 5 makes gas bag be deflated to shrivelled state, drainer
It completes.
