Description
Technical field
The present invention relates to a kind of borehole sealing test unit, relate in particular to a kind of test unit for simulation both-end shutoff boring effect.
Background technology
In the colliery, especially fissure zone is grown in the ripe coal mine roof plate, usually need to detect the size in top board crack with the leak hunting method of vector of water filling, namely hole to roof by specialized equipment, water filling in a certain section of boring, water permeates in top board by the crack, when water filling reaches capacity, according to actual water injection rate, namely wastage, judge the size in crack in the top board, thereby draw the development degree in crack.
But in actual applications, existing equipment can only detect wastage, the relation between detection wastage that can't be quantitative and water injection pressure, the water injection time.To same coal seam, its wastage of different water injection pressures and water injection time probably is different, and at the workplace of some feature, its difference may be very large.
In the prior art, wastage and water injection pressure, the clear and definite corresponding relation of water injection time do not have suitable test unit and equipment to determine above-mentioned relation yet.This situation has affected the application of both-end shutoff crack detection method greatly.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of boring both-end shutoff simulator stand, comprises support and simulation water injection pipe,
Described support comprises base, platen and hydraulic cylinder, described platen is the rectangle sheet metal, the one end is free end, the other end is hinged on the described base, described hydraulic cylinder is fixedly installed on the described base, the piston of described hydraulic cylinder is fixedly connected with described platen, is used for promoting described platen and rotates around its jointed shaft, to adjust the angle between itself and the base;
Described simulation water injection pipe is fixedly installed on the described platen, the sealed plug sealing in its two ends, have a plurality of water inlets and a plurality of Multifunctional mouth on the pipe shaft of described simulation water injection pipe, described water inlet axially evenly distributes along described simulation water injection pipe, at least one water inlet connects water pump, the water inlet that does not connect water pump uses plug seal, and described Multifunctional mouth connects the crack simulator along the axial distribution of described simulation water injection pipe at least one described Multifunctional mouth.
Bonding pressure table on preferred at least one described Multifunctional mouth.
Preferred described simulation water injection pipe has many, and many simulation water injection pipes are set in parallel on the described platen.
The invention has the advantages that: simple in structure, failure rate is low; But the angle of free adjustment simulation water injection pipe is fully simulated the water filling situation of holing under the different angles; Water inlet evenly distributes along pipe shaft, avoids the pressure surge of water filling on the impact of test figure; Multifunctional mouth is set, changes the purposes of Multifunctional mouth by changing external equipment, easy to use.

Embodiment
Referring to accompanying drawing 1-2, it has described a specific embodiment of boring both-end shutoff simulator stand of the present invention.This testing table mainly comprises support and simulation water injection pipe.
Support integral body is made of metal, comprising base, platen and hydraulic cylinder.Platen is the rectangle sheet metal, and it is the basis of carrying simulation water injection equipment.The four edges of platen is called after first side, Second Edge, the 3rd limit and the 4th limit successively, and its first side is free end, and the 3rd limit is hinged on the base, and it can be rotated around the 3rd limit.Hydraulic cylinder is fixedly installed on the base and directly and places on the ground, and its piston is fixedly connected with platen, is used for promoting platen and rotates around its jointed shaft the 3rd limit, to adjust the angle between platen and the base.
The simulation water injection pipe is the core component of testing table, and it is fixed on the platen, preferably with vertical setting the in jointed shaft the 3rd limit of platen.Water injection pipe is roughly cylindrical shape, and the sealed plug sealing in its two ends has a plurality of water inlets and a plurality of Multifunctional mouth on the pipe shaft of water injection pipe, and water inlet and Multifunctional mouth arrange in the both sides of pipe shaft respectively.Water inlet axially evenly distributes along the simulation water injection pipe, and one or more water inlets connect water pump, is used for to the water injection pipe water filling, connects general pressure table and flowmeter on the water pump, and the water inlet that does not connect water pump uses plug seal, avoids leaking.Multifunctional mouth can be installed the devices such as crack simulator or tensimeter along the axial distribution of simulation water injection pipe on it.The crack simulator is used for crack and the space in simulation coal seam, can use the blind pipe with aperture or finedraw to be used as the crack simulator, also can use other suitable parts, by adjusting size and the quantity of aperture and finedraw, just can simulate different crack situations.Be the better concrete environment of simulation, can different crack simulators be installed at the Multifunctional mouth of a plurality of different positions.As shown in this embodiment, in totally three Multifunctional mouths, below two Multifunctional mouths the crack simulators are installed, above setting pressure table on Multifunctional mouth, same, do not connect crack simulator or manometric Multifunctional mouth if having, also need to use plug seal, leak avoiding.
For carrying out simultaneously a plurality of tests, many simulation water injection pipes can be set, many simulation water injection pipes can be set in parallel on the platen.
In use, at first need according to actual conditions, at the simulation water injection pipe suitable crack simulator is set, then open water pump priming, record simultaneously manometric reading in general pressure table, flowmeter and the simulation water injection pipe, and the drafting time plot, thereby draw in the situation of different cracks amount the relation of different injection pressure, water injection rate and water injection time.
The above; only be the better embodiment of patent of the present invention; but the protection domain of patent of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that patent of the present invention discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of patent of the present invention.
