Description
Technical field
The present invention relates to the air feed system being used in mine.
Background technology
With the development of pit mining technology, often constructed using big cross section in underground, this causes the gas use of underground
Amount increase.To solve the problems, such as that gas safety employs the air supply device of high-power blower at present, the air supply device is by located at lane
Air duct in road is blown to tunnel, so that gas is discharged along return air circuit.The security of this drawing-off gas mode with
Air force in blower fan feeding tunnel is relevant, if the air quantity in feeding tunnel is more than safe air quantity, return meet
Gas density necessarily exceed regulation, so as to cause great potential safety hazard, if the air quantity of blower fan is too small, underground can not be made again
Gas fully discharge, have hidden danger to the personal safety of downhole operations personnel.Due to all not having on current air supply device and air duct
The device of air force is controlled according to real-time condition, therefore the security of drawing-off gas is relatively low.
The content of the invention
The invention provides a kind of air feed system in mine, the gas by real-time detection return meet is dense
Degree automatically controls the air quantity in feeding tunnel, improves the security of mine operation.
The present invention is for the air feed system in mine, including is arranged on the air duct in tunnel, and air duct is provided with and return air line
The part flow arrangement of road connection, the part flow arrangement is connected by motor with control device, and the input of control device is connected at
The methane Concentration Measurement device of return meet.The effect of part flow arrangement is that the wind in air duct is diverted in return air circuit,
Reduce the air quantity in air duct.Methane Concentration Measurement device uses existing device, when methane Concentration Measurement device is detected
After the gas density of return meet reaches given threshold, control device is sent signal to, control device starts motor, leads to
Part flow arrangement is crossed to shunt the air quantity in air duct.As a result of above-mentioned automatic detection, the mode for automatically controlling, it is not necessary to
Manually part flow arrangement is controlled, while reducing person works' amount, additionally it is possible to real-time monitoring and control gas concentration, pole
The security of big raising mine operation.
Specifically, described part flow arrangement includes thering is an input and two three-way connections of output end, described two
Individual output end is respectively equipped with control valve, and two output ends connect air duct and return air circuit respectively, by two controls of output end
The cooperation of valve is controlled to the air quantity in the air quantity in air duct and return air circuit.
Further, the linkage structure for making described two control valve synchronous backwards opening/closing is provided with described three-way connection,
When a control valve does closing motion, another control valve does breakdown action simultaneously, is achieved in two outputs of Synchronization Control
The air quantity at end.
A kind of concrete structure for controlling valve is, the control valve includes folding valve plate, and for control valve plate open/
The pull rope for closing, two pull ropes of the valve plate of control valve are wrapped in same rotating shaft with mutually opposite direction, rotating shaft
One end connects described motor through the outer wall of three-port structure.It is described to be wrapped in same rotating shaft with mutually opposite direction
Pull rope, piece wound clockwise of the pull rope being connected with two valve plates for referring in rotating shaft, another wrapped anti-clockwise, this
Sample necessarily causes that two pull ropes one take up when rotating shaft is driven by motor and rotated, and one is loosened, and realizes two valve plates simultaneously
Opposite action.
Further, part flow arrangement is located at the exit in tunnel and near the air inlet side of air duct.Because return converges
Be typically at conjunction in tunnel near exit, thus by part flow arrangement located at tunnel exit air duct air inlet, so from point
The wind of stream device shunting will not be sent in the return air circuit of tunnel depths, it is to avoid offset the effect of shunting indirectly.
Further, described control device is single chip computer architecture, the control program those skilled in the art in single-chip microcomputer
Can be realized according to conventional programming mode, not be present invention content.Single-chip microcomputer is real-time by methane Concentration Measurement device
The concentration of detection, the opening time of controlled motor, is achieved in intelligence, automatically controls the opening/closing of part flow arrangement difference output end
Time.
The present invention is capable of the gas density of real-time detection return meet for the air feed system in mine, and automatically
The air quantity in control feeding tunnel, reduces the gas density of return meet, effectively increases the security of mine operation.
Specific embodiment with reference to embodiments, is described in further detail again to the above of the invention.
But this scope for being interpreted as above-mentioned theme of the invention should not be only limitted to following example.Think above-mentioned technology of the invention is not departed from
In the case of thinking, according to various replacements or change that ordinary skill knowledge and customary means are made, this hair all should be included in
In bright scope.
