The utility model discloses to detect with controlling element integratedly in by mining NULL DC power supply control box, and be equipped with the detection that the super temperature of belt conveyor and burning smog were accomplished to outside mining smoke transducer, mining temperature sensor and mining flame proof solenoid valve, control flame proof solenoid valve switches on the cooling of sprinkling, eliminates the accident at in the bud, has that equipment operation is simple, the wiring is convenient, the operation stably, the maintenance simply, input cost low grade advantage.
Description
Technical field
This utility model is used in be had in damp (methane) and the mine of coal dust, it is possible in conveyer running when overtemperature or generation smog, controlling electromagnetic valve even load and automatically works, carrying out watering cooling, thus avoiding bigger security incident.
Background technology
Ribbon conveyer be colliery production process in the visual plant of raw coal transportation; ribbon conveyer usually can because of overload in running; belt creep or bearing wear cause belt conveyer roller to seize up or bearing local temperature is too high and the pyrophoricity accident that causes; in there is damp (methane) and the mine of coal dust, it is also possible to set off an explosion.The solution in current most of colliery has manual inspection and adopts embedded control system to carry out detecting and report to the police.The method of manual inspection has the disadvantage in that labor strength is big and can not find overtemperature trouble point in time, thus incuring loss through delay the process time to cause bigger security incident；Adopt the detection of embedded system and the method reported to the police, there is system wiring complexity, the shortcomings such as input cost is big, and operation easier is big, general personnel not easily grasp.
Summary of the invention
The purpose of this utility model is in that to provide a kind of automatic sprinkling dust suppression device for mines, Detection & Controling element is integrated in one piece of mine explosion-suppression and intrinsic safety type DC power control case having discrete component to constitute, it is equipped with the mine smoke sensor of outside, mining temperature sensor and mine explosion-suppression electromagnetic valve and completes the detection of ribbon conveyer overtemperature and combustion fumes, control electromagnetic valve of explosion isolation conducting and carry out watering cooling, accident is eliminated in bud.
The technical scheme that this utility model adopts for achieving the above object is:
A kind of automatic sprinkling dust suppression device for mines, including mine explosion-suppression and intrinsic safety type DC power control case, mine smoke sensor, mining temperature sensor, mine explosion-suppression electromagnetic valve and supply channel, described mine smoke sensor, mining temperature sensor, mine explosion-suppression electromagnetic valve are connected with mine explosion-suppression and intrinsic safety type DC power control case respectively, mine smoke sensor is connected with mining temperature sensor, and mine explosion-suppression electromagnetic valve is connected with supply channel.
Further, described mine explosion-suppression and intrinsic safety type DC power control case is made up of discrete component, and Detection & Controling element is integrated by described discrete component.
Further, described Smoke Sensor connects+12V power supply.
The beneficial effects of the utility model are: Detection & Controling element is integrated in one piece of mine explosion-suppression and intrinsic safety type DC power control case having discrete component to constitute by this utility model, it is equipped with the mine smoke sensor of outside, mining temperature sensor and mine explosion-suppression electromagnetic valve and completes the detection of ribbon conveyer overtemperature and combustion fumes, control electromagnetic valve of explosion isolation conducting and carry out watering cooling, accident is eliminated in bud, have that equipment is simple to operate, easy-to-connect, stable, safeguard the advantages such as simple, input cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of automatic sprinkling dust suppression device for mines.
Detailed description of the invention
Following by specific embodiment and in conjunction with accompanying drawing, this utility model is described.These embodiments are provided so that the disclosure will be entirely clear from, and scope of the present utility model is fully conveyed to those skilled in the art.
This automatic sprinkling dust suppression device for mines is made up of mine explosion-suppression and intrinsic safety type DC power control case 1, mine smoke sensor 2, mining temperature sensor 3, mine explosion-suppression electromagnetic valve 4 and supply channel, mine smoke sensor, mining temperature sensor, mine explosion-suppression electromagnetic valve are connected with mine explosion-suppression and intrinsic safety type DC power control case respectively, mine smoke sensor is connected with mining temperature sensor, and mine explosion-suppression electromagnetic valve is connected with supply channel.Device composition frame chart is as it is shown in figure 1, device work process is as follows:
(1) work process of DC power control case: plus, after 127V power supply, exporting+12V DC voltage between G and 0 and work for Smoke Sensor between 9# and 8#.During normal operation, controlling end j0 is high level, and 1# and 9# is obstructed, and electromagnetic valve does not work, and does not also sprinkle water.When j0 is low level, 1# and 9# connects, electromagnetic valve work, starts watering.
(2) work process of overtemperature watering: being a normal opened contact inside temperature sensor, its two ends are coupled with j0 and 0 end of DC power control case, when the temperature increases (42 DEG C ± 2 DEG C), junction closure, j0 becomes 0 level, makes 1# and 9# connect, electromagnetic valve obtains electric work, carries out watering cooling.
(3) work process of smog watering: Smoke Sensor must have+12V power supply to work, and is a normal opened contact between YW end and 0, when protecting when there being smog to reach; junction closure, j0 becomes 0 level, makes 1# and 9# connect; electromagnetic valve obtains electric work, carries out watering cooling.
Detection & Controling element is integrated in a mine explosion-suppression and intrinsic safety type DC power control case having discrete component to constitute by this utility model, be equipped with the mine smoke sensor of outside, mining temperature sensor and mine explosion-suppression electromagnetic valve complete the detection of ribbon conveyer overtemperature and combustion fumes and control electromagnetic valve of explosion isolation conducting and carry out watering cooling, accident is eliminated in bud, have that equipment is simple to operate, easy-to-connect, stable, safeguard the advantages such as simple, input cost is low.
It should be noted that; above-mentioned specific embodiment is merely exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and deformation on the basis of above-described embodiment, and these improve or deformation all falls within protection domain of the present utility model.
