Abstract
The utility model discloses a kind of convenient drainage arrangements of deep hole, including collector pipe compatible with blasthole diameter, in the lower end of collector pipe, cutting ferrule is set, described cutting ferrule one end outer wall is caught in the lower end of collector pipe, the cutting ferrule other end is provided with through-hole, it is covered in the through-hole inner face and matches elastic open seal cover with through-hole, one end of open seal cover is provided with the locating piece for fixing open seal cover.Using the technical program, under natural conditions, fan-shaped open seal cover is in closed state；When draining, drainage arrangement lower end is pressed into the blasthole of ponding, open seal cover is opened by water slug pressure under the action of external force and water, when device carries upwards, due to the active force that water in device is downward, open seal cover is covered on through-hole by the downward pressure of water, to make through-hole seal, after device is all finally proposed blasthole, water is poured out, a draining is completed, repeatedly cycle 90% or more water can will be discharged outside blasthole in blasthole.
Description
Technical field
The utility model is related to the outdoor cubic metre of earth and stone, levelling of the land, flat base engineering explosion Shothole pumping gear, especially
A kind of convenient drainage arrangement of deep hole.
Background technology
In the blasting engineerings such as levelling of the land engineering explosion, the cubic metre of earth and stone, blasthole ponding is relatively conventional when rainy season, by water
It influences, explosive utilization rate is low, in fact it could happen that miss-fire, the bad control of explosive payload, dose dress cannot reach ideal demolition effect, medicine less
Amount dress is more even to cause safety accident.
Utility model content
The utility model is intended to provide a kind of convenient drainage arrangement of deep hole, it is ensured that drainage arrangement is simple in structure, is conveniently operated.
To achieve the above object, the utility model provides the following technical solutions:
A kind of convenient drainage arrangement of deep hole, including collector pipe compatible with blasthole diameter are arranged in the lower end of collector pipe
Cutting ferrule, described cutting ferrule one end outer wall are caught in the lower end of collector pipe, the cutting ferrule other end are provided with through-hole, in the through-hole
Inner face is covered with to match elastic open seal cover with through-hole, and one end of open seal cover is provided with the locating piece for fixing open seal cover.
Fan-shaped cross section for the open seal cover.
As a further improvement, being provided with torsionspring, one end of torsionspring one end and open seal cover in locating piece side
Connection.
As a further improvement, diaphragm seal is arranged in through-hole edge surrounding, sealed in the off state convenient for open seal cover logical
Hole.
Using above-mentioned technical proposal, under natural conditions, fan-shaped open seal cover is in closed state；When draining, by drainage arrangement
Lower end is pressed into the blasthole of ponding, and open seal cover is opened by water slug pressure under the action of external force and water, under drainage arrangement
Drawdown degree is deeper, and open seal cover open angle is bigger, when pushed up at open seal cover most short side to drainage arrangement bottom into 45 degree of angles, unpacking
Lid open angle is not further added by, into drainage arrangement water start it is constant.Device starts to contact the water surface to by artificial complete pressure
It is in water to this whole process of blasthole bottom and flows into unit state；After device lower end is all contacted with blasthole bottom, it will arrange
Water installations up carry, and when device carries upwards, due to the active force that water in device is downward, the downward pressure of water covers open seal cover
On through-hole, to make through-hole seal, after device is all finally proposed blasthole, water is poured out, that is, completes a draining,
Repeatedly cycle 90% or more water can will be discharged outside blasthole in blasthole.
Description of the drawings

Fig. 2 is another structural schematic diagram of the utility model in nature
Fig. 3 is structural schematic diagram of the utility model in hull-borne；
Fig. 4；The structural schematic diagram of open seal cover；
In attached drawing：1 collector pipe, 2 cutting ferrule, 21 through-hole, 22 side wall, 3 open seal cover, 4 locating piece, 5 torsionspring.
Specific implementation mode
With reference to 1-Fig. 4 of figure, a kind of convenient drainage arrangement of deep hole, including collector pipe 1 compatible with blasthole diameter, it catchments
Pipe 1 is pvc pipe, and 1 diameter of collector pipe is determined according to blasthole diameter, and the length of collector pipe 1 is slightly larger than blast hole depth.
Cutting ferrule 2 is set in the lower end of collector pipe 1, that is, cutting ferrule 2 is assemblied in the lower end of collector pipe 1, cutting ferrule 2 can be torn open
It unloads, 2 one end side wall 22 of the cutting ferrule is caught in the lower end of collector pipe 1, and 2 one end side wall 22 of cutting ferrule and the inner wall of collector pipe 1 are interference
Cooperation.
2 other end of the cutting ferrule is provided with through-hole 21, fan-shaped cross section in the through-hole 21,21 inner face of through-hole
It is covered with and matches elastic open seal cover 3 with through-hole 21, the cross section of certain open seal cover 3 is fan-shaped, is provided in one end of open seal cover 3
Locating piece 4 for fixing open seal cover 3, locating piece 4 are fixed on 2 end face of cutting ferrule with pin.
As a further improvement, being provided with torsionspring 5,5 one end of torsionspring and open seal cover 3 in 4 side of locating piece
One end connects, and certainly, during collector pipe 1 is inserted into blasthole, the torsion of torsionspring 5 is necessarily less than the water of blasthole to open seal cover
3 pressure, setting torsionspring 5 is convenient for increase open seal cover 3 to the leakproofness of through-hole 21.
As a further improvement, diaphragm seal is arranged in 21 edge surrounding of through-hole, sealed in the off state convenient for open seal cover
Through-hole does not draw diaphragm seal in attached drawing.
