Detailed description of the invention (the present embodiment is only one of numerous embodiment, is not the full content of claim, does not have restriction to claim)

The utility model is primarily of limit switch 1, valve 2, rope 3, spring 4 forms, limit switch 1 is provided with normally closed interlock and normally open contact, it is characterized in that: limit switch 1 and valve 2 are fixedly installed on other object, valve handle 5 acts on to enable possition by spring 4 by valve 2, rope 3 is arranged on directly over combustibles, the shift bar 6 of limit switch 1 is pulled to compression position and valve handle 5 is pulled to closed position by the two ends of rope 3 respectively, or on the shift bar 6 that one end of two ropes 3 is separately positioned on limit switch 1 and valve handle 5, and two rope 3 other ends are arranged on other object, or one end of rope 3 controls an interlock body 7, this interlock body 7 controls the shift bar 6 of limit switch 1 more respectively or/and the valve handle 5 of valve 2.The vertical direction of described rope 3 is provided with the blade 8 that can cut off rope 3, and this blade 8 is connected with stressed plate 9 by link gear.Because the shift bar 6 of limit switch 1 is pulled to compression position and valve handle 5 is pulled to closed position by the two ends of rope 3 respectively, normally closed interlock on limit switch 1 and normally open contact state is now just in time contrary with original state, and valve 2 is also in closed condition, at this moment the normally open contact on supply socket circuit is serially connected in because the compression of rope 3 is just in conducting state, supply socket there is electric current export, the shower nozzle 10 being arranged on combustibles surrounding is pulled to closed position due to valve handle 5 by rope 3, does not have extinguishing chemical ejection in shower nozzle 10; And be originally serially connected in the normally closed interlock in warning circuit due to the compression of rope 3 and be just in off-state, the warning so alarm can not pipe.When fire incident occurs, the spontaneous combustion of fault electrical equipment produces flare, rope 3 above combustibles can be blown during flare burning, such limit switch 1 shift bar 6 and valve handle 5 just lose the constraint of rope 3 and homing, such supply socket will cause circuit to be cut off because serial connection limit switch 1 in circuit resets, thus ensures safety; And originally do not have the warning circuit of conducting will cause circuit turn-on because of the reset of serial connection limit switch 1 in circuit, thus cause the warning that pipes of warning circuit, put out a fire in order to remind people; Same valve handle 5 resets after the constraint losing rope 3 under the effect of spring 4, the valve 2 of original closedown is opened because of the reset of valve handle 5, at this moment extinguishing chemical just sprays to burning objects by valve 2 from shower nozzle 10, and flare can be extinguished in the starting stage in most cases.

Specific embodiment of the utility model two as shown in Figure 2, the present embodiment and the difference of embodiment one are that the rope 3 on limit switch 1 shift bar 6 is separately fixed on different objects with the rope 3 on valve handle 5, and the object that can arrive and successively control is set respectively, what such as arranged by the rope 3 on limit switch 1 shift bar 6 is lower, can arrive first cuts off the electricity supply sprays the scheme of extinguishing chemical again, and other side is roughly the same.

Specific embodiment of the utility model three as shown in Figure 3, the difference of the present embodiment and upper two embodiments is that rope 3 first drives the body 7 that links, and the body 7 that links is provided with the space supplying the control handle of shift bar 6 and valve handle 5 and other parts to enter, when rope 3 blows because interlock body 7 to lose after the constraint of rope 3 return under the action of the spring, the control handle of these correspondences just enters space corresponding on interlock body 7 under the effect of spring or elastomeric objects, the action of these control handles causes being controlled object and works according to the requirement of subscribing, thus arrival expected effect.The embodiment of this interlock body structure has many, and the technical scheme that the similar structure of every employing reaches this patent same effect also belongs to the art of this patent characteristic range.

Specific embodiment of the utility model four as shown in Figure 4, the difference of the present embodiment and upper several embodiment is that rope 3 is not blown by flare, but by a set of link gear band cutting blade 7, rope 3 is cut off, because the generation of electrical equipment accident occurs cruelly to explode phenomenon sometimes, and the generation of sudden and violent fried phenomenon not necessarily has flare sometimes, if rope 3 is not blown, the warning originally considered, automatic fire-extinguishing function just possibly cannot realize, so the generation that this structure explodes accident cruelly for electrical equipment designs; During sudden and violent fried generation, stressed plate 8 blows by sudden and violent fried shock wave, and stressed plate 8 rotates the motion of rear drive steel wire, then cuts rope 3 by pierce tap cutting blade 7, just can automatic cut-off power and self-extinguishing after rope 3 is cut-off.

Although maximum feature of the present utility model is to touch control device for control circuit, itself need not consume electric energy, and reliability is high, and the life-span is long, and cost is low.In the utility model, extinguishing chemical is except adopting powder extinguishing agent, except carbon dioxide extinguishing agent, also can adopting running water, because now circuit is cut off, and running water can ejecting extinguishing for a long time.

Right of the present utility model is except the above-mentioned embodiment exemplified; for embodiment still its technical characteristic and the identical embodiment of this claim content that some do not exemplify in description, also belong to the claims of this patent completely.
