Description
Technical field:
The utility model relates to the Protrudent set of guarding against contrary wind for gas that uses under a kind of coal mine.
Background technology:
Gas is outstanding to be one of the major casualty factor in colliery, and it is under the unexpected release action of the inner mash gas dynamic in coal seam, coal and gas is gushed out fast caused the accident.Outstanding the mostly occurring of large-scale gas has the driving face of outburst danger, very easily causes whole exploiting field to cause gas explosion against the wind after the generation, and the coal of gushing out stops up and destroys tunnel, the safety that is greatly threatening down-hole miner.According to outstanding crash analysis, inducing when occurring in the coal road driving more than 95% and blowing out is outstanding.When the workman implements the bursting work of coal road driving at present, all be to hide behind the safety area the staff, implement to blow out operating process again, the workman can not initiatively prevent the harm of coal and gas burst accident effectively, in case generation gas burst accident, very easily cause ventilation system contrary wind even gas explosion, enlarge damaging range and involve other area.
The utility model content:
The purpose of this utility model provides a kind of after driving face generation gas is outstanding, can stop outstanding energy unofficial biography, and the gas of avoiding gushing out causes against the wind to other area impact, effectively reduces the Protrudent set of guarding against contrary wind for gas of outstanding accident impact scope.
To achieve these goals, the utility model comprises: Holder for hanging household utensiles, doorframe, high-pressure air pipe, air-operated solenoid valve, signal processor, turning cylinder, the protrusion-dispelling door-plate, Removable hook, cylinder, gas is given prominence to sensor, Removable hook is connected on the Holder for hanging household utensiles by little rotating shaft, doorframe is fixed on tunnel wall and the back, the outstanding inductor of gas is hung on back, cylinder, air-operated solenoid valve, signal processor is fixed on the back, cylinder is connected with high-pressure air pipe and is controlled by air-operated solenoid valve, the protrusion-dispelling door-plate is connected to the top of doorframe by turning cylinder, the left end of protrusion-dispelling door-plate is supported by Removable hook, and the piston termination of cylinder is connected with Removable hook.
Like this, when coal road driving face generation gas burst accident, form the gas that very big impact involves high concentration, the outstanding sensor of gas is transported to signal processor with outstanding induced signal, signal processor control air-powered electromagnetic valve events, air-operated solenoid valve is connected high-pressure air pipe, the piston head drive Removable hook of cylinder is moved to the left, the left end of protrusion-dispelling door-plate loses the support of hook, hurtle down by deadweight, cover on doorframe, the tunnel is closed, stop outstanding energy unofficial biography, avoid outstanding gas and coal to feed through to other area, outstanding influence basin is narrowed down between this device and the driving face, prevent against the wind and the expansion of accident, reduce economic loss, ensured miner's life security.Have characteristics such as simple in structure, safe and practical, that effect is obvious.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model comprises: Holder for hanging household utensiles 2, doorframe 6, high-pressure air pipe 7, air-operated solenoid valve 8, signal processor 9, turning cylinder 11, protrusion-dispelling door-plate 12, Removable hook 13, cylinder 14, the outstanding sensor 15 of gas.Removable hook 13 is connected on the Holder for hanging household utensiles 2 by little rotating shaft, and Removable hook 13 can rotate.Doorframe 6 is fixed on tunnel wall and the back, the outstanding sensor 15 of gas should hang with the nearer back 1 of driving face on, the outstanding sensor 15 of gas be that gas concentration sensor or gas are given prominence to pressure sensor.Cylinder 14, air-operated solenoid valve 8, signal processor 9 are fixed on the back 1, and air-operated solenoid valve 8 and signal processor 9 should be arranged on the right part certain distance of doorframe 6, when blowing out to satisfy to the requirement of its supply voltage grade.The outstanding sensor 15 of gas is connected to the input of signal processor, output control air-operated solenoid valve 8 actions of signal processor 9, cylinder 14 is connected with high-pressure air pipe 7 and by air-operated solenoid valve 8 controls, the source of the gas of high-pressure air pipe can be provided by the down-hole high pressure self-help apparatus.Protrusion-dispelling door-plate 12 is connected to the top of doorframe 6 by turning cylinder 11, the left end of protrusion-dispelling door-plate 12 is supported by Removable hook 13, protrusion-dispelling door-plate 12 adopts wood materials to be processed into, and produces spark in the time of can avoiding protrusion-dispelling door-plate 12 with the doorframe collision, and the piston termination of cylinder 14 is connected with Removable hook 13.On back 1, be fixed with fixed pulley 4, be fixed with movable pulley 3 on protrusion-dispelling door-plate 12, an end of pull rope 5 is fixed on the back 1, and the other end is fixed on the hand winch 10 by movable pulley and fixed pulley, so that after protrusion-dispelling door-plate 12 cuts out, utilize hand winch to open easily.Signal processor 9 is provided with reset button, and control cylinder drives the Removable hook move left and right easily, makes the state that the miner is arranged on the protrusion-dispelling door-plate smoothly to be needed.Air-operated solenoid valve 8, signal processor 9, the outstanding sensor 15 of gas should adopt essential safe type, the sensitivity induction numerical value of the outstanding sensor 15 of gas, should adjust setting according to on-site actual situations, to guarantee in normal condition and the Shi Buhui that blows out action, and sensitive reliable when gas is outstanding, and meet the safety regulations in coal mine requirement.
