Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the present invention is further illustrated.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of blast mining face blows out rear wind and water combined spraying automatic open device, the unlatching
Device includes being made up of purification water curtain device 2 and control circuit；Purification water curtain device 2 includes shower nozzle 2-1, geomantic omen pipe 2-2, wind band
2-4, water band 2-5；Geomantic omen pipe 2-2 is T-shaped triple valve, and the supervisor of the T-shaped triple valve is connected by pipeline with shower nozzle 2-1, the T
It is connected respectively with wind band 2-4, water band 2-5 on the bifurcated pipe of type triple valve.Shower nozzle 2-1 by geomantic omen pipe 2-2 and wind band 2-4,
Water band 2-5 is connected；Control circuit includes voltage sensitive sensor 8 and the time relay 9；The normally opened contact S1 of voltage sensitive sensor 8 with
The coil of the time relay 9 mutually concatenates, the normally opened contact S2 of the time relay 9 with the normally opened contact S1 phases of voltage sensitive sensor 8 simultaneously
Connect；The coil of the time relay 9 electrically connects with wind with 2-4 and water with the motorized adjustment ball valve 10 in 2-5 respectively further through wire,
To start and stop motorized adjustment ball valve 10, so as on or off wind band 2-4 and water band 2-5.
Shower nozzle 2-1 is made using Φ 108mm pipeline processing, and both ends are welded with the thick steel plate 2a of 6mm, on shower nozzle 2-1
Provided with the spray eye 2b that multiple rows of aperture is 5mm.Two neighboring spray eye 2b level intervals are 15mm, and vertical spacing is 15mm；Multiple sprays
It is in equilateral triangle shape between eye 2b.
The time relay 9 uses power-off delay relay, and the power cut off delay time that power-off delay relay is set is
25min, the set power cut off delay time to be achieved, automatically cut off the power supply of motorized adjustment ball valve 10, so as to cut off wind band 2-4,
Water band 2-5 pipelines.
Wind is connected with Φ 108mm high-pressure air hoses again with 2-4 and water with the pipeline that 2-5 is Φ 25mm, Φ 25mm wind band 2-4
Logical, Φ 25mm water band 2-5 is connected with Φ 108mm high-pressure water pipes again.
Wind band 2-4 and water band 2-5 are fixed on tunnel by drawstring 6 and holding card 11 and helped.
The present invention another technical scheme be：
A kind of blast mining face blows out rear wind and water combined spraying automatic open device, and the opening device is included by purification water curtain device
2 and control circuit composition；Purification water curtain device 2 includes shower nozzle 2-1, geomantic omen pipe 2-2, wind band 2-4, water band 2-5；Geomantic omen pipe 2-2
For Y shape steel tubes, the supervisor of the Y shape steel tubes is connected with shower nozzle 2-1, passes through snap joint 2-3 on the bifurcated pipe of Y shape steel tubes respectively
It is connected with wind band 2-4, water band 2-5.Shower nozzle 2-1 is connected by geomantic omen pipe 2-2 with wind band 2-4, water band 2-5；Control circuit
Including voltage sensitive sensor 8 and the time relay 9；The normally opened contact S1 of voltage sensitive sensor 8 mutually goes here and there with the coil of the time relay 9
Connect, the normally opened contact S2 of the time relay 9 and the normally opened contact S1 phases of voltage sensitive sensor 8 simultaneously connect；The coil of the time relay 9 is again
Electrically connected respectively with wind with 2-4 and water with the motorized adjustment ball valve 10 in 2-5 by wire, to start and stop motorized adjustment ball valve
10, so as on or off wind band 2-4 and water band 2-5.
The present invention principle be：
The shock wave when device make use of the gun diging face to blow out, causes voltage sensitive sensor to act due to shock wave,
So as to furthermore achieved that voltage sensitive sensor normally opened contact S1 is closed, therefore it is electric to cause time relay coil to obtain, so as to enter again
One step realizes time relay normally open contact S2 closures, and the time relay realizes self-insurance, only reaching the time relay
After set time delay, relay coil just can dead electricity, so as to ultimately result in motorized adjustment ball valve dead electricity and cut off with
Wind that shower nozzle is connected, water lines.
As shown in Fig. 2 the requirement of the device in use is as follows：
1）, the device effectively make use of shock wave when blowing out, so as to realize pressure-responsive using shock wave when blowing out
The action of device 8, so as to ultimately result in the Φ 25mm wind being connected with shower nozzle 2-1, water band is connected, and the device has also passed through power-off in addition
Time-delay relay, which realizes, automatically cuts off air feed, supply channel.
2）, the wind and water combined sprayer unit be installed on and met head on away from driving face 1 in the range of 50 ~ 150m, if installation position
Distance is put to meet head on too closely, not having maximally effective atomizing de-dusting effect not only, but also can damage because moving back and forth equipment of meeting head on
The bad automatic sprayer；If the spraying automatic open device mounting distance meets head on too far, equally to will also result in atomizing de-dusting effect
Fruit declines, and is also possible to that to blow out place too remote because of its distance in addition, so as to cause shock wave that voltage sensitive sensor 8 can not be promoted to act；
The device shower nozzle 2-1 is anchored at back 4 by anchor pole 3, and shower nozzle 2-1 is arranged on tunnel center, away from lane
Road bottom plate 5 is not less than 2000mm, can either ensure the power of shock wave and can realize the action of pressure-responsive 8, and and can reaches
Guarantee equipment of meeting head on moves back and forth the problem of will not damaging the auto spraying dust arrester；
3）, the voltage sensitive sensor 8 used in the device be installed on tunnel and help, and the distance away from tunnel side cannot be less than 200mm, separately
Outside, and the device installation site is able to ensure that and realizes that voltage sensitive sensor 8 acts using shock wave when blowing out；
4）, all kinds of electrical equipments used in the device be explosion-proof component, and the electrical equipment involved by the device must not pacify
Mounted in the place for having water drenching, electrical equipment coil voltage used is 127V；
5）, power cut off delay time for setting of power-off delay relay used in the device be 25min, therefore the 25min after blowing out
The power-off delay relay coil is by automatic dead electricity afterwards, so as to cause the normally opened contact of the time relay 9 to disconnect, so as to eventually through
Motorized adjustment ball valve 10 has cut off Φ 25mm water bands and Φ 25mm wind bands.
With prior art ratio, the present invention is distinguished and admirable to the dust-laden in mine laneway to be purified, can be with the elimination of all standing
Dust；The setting of the present invention simultaneously does not influence personnel in lane and passed through, and the current after purification are thoroughly discharged by gutter, and discharge water is also
Reusable edible.
Shock wave when blowing out rationally effectively is make use of, it is achieved thereby that the action of voltage sensitive sensor 8, so as to further
Realize motorized adjustment ball valve 10 and obtain effect that is electric and causing wind to be automatically opened up with 2-4, water with 2-5, avoid and manually open
Open the troublesome problem of wind power ganged sprayer unit.
The principle of power-off delay relay coil automatic dead electricity after delay time is rationally effectively make use of, so as to lead
Its normally opened contact is caused to disconnect, so as to further result in the dead electricity of motorized adjustment ball valve 10 being serially connected with Φ 25mm wind band, water band, most
Cause motorized adjustment ball valve 10 to be closed eventually and realize wind, water band and Φ 108mm high-pressure water pipes and Φ 108mm high-pressure air hoses break
Open.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
