Abstract

The invention discloses a self-extinguishment insulation box. The self-extinguishment insulation box comprises a box body. Two exhaust hoods are arranged on the top wall in the box body. A foam sprayer is arranged on the portion, between the two exhaust hoods, of the top wall of the box body. Smoke sensors are arranged on the side walls of the box body. A time delay switch is arranged in the foam sprayer and electrically connected with the smoke sensors. The exhaust hoods are connected with corresponding exhaust pipes. Each exhaust pipe extends to the corresponding side wall of the box body along the top wall of the box body, then extends to the bottom of the box body along the corresponding side wall of the box body, then penetrates out of the corresponding side wall of the box body and extends into a filtering box upwards. The filtering box is fixed to the side wall of the outer portion of the box body and filled with filtering liquid. The height of the liquid level of the filtering liquid is higher than that of pipe openings of the exhaust pipes. By the adoption of the self-extinguishment insulation box, automatic extinguishment can be achieved when an electric appliance in the box fails and is on fire, the insulation box can be effectively prevented from bursting when the arcing failure is generated in the box body, and emission of poisonous and harmful gas generated due to the failure can be reduced.

Description

A kind of from putting out a fire insulated case

Technical field

The present invention relates to a kind of from putting out a fire insulated case.

Background technology

Insulated case has been obtained for being widely applied in the installation process of power equipment, but in the process used, equipment in case is likely to occur arcing fault, gas can be heated to expand rapidly and impact casing, cause tank breaks thus other equipment of damaging around casing, cause bigger potential safety hazard.

Summary of the invention

Present invention is generally directed to the technical problem existing for prior art, thus providing a kind of to be prevented from the insulated case of casing explosion when there is arcing fault.

The present invention is a kind of from putting out a fire insulated case, including casing, the roof of box house is provided with two exhaust hoods, box top wall between two exhaust hoods is provided with foam sprinkler, the sidewall of casing is provided with Smoke Sensor, delay switch, delay switch and Smoke Sensor electrical connection it is additionally provided with in the inside of foam sprinkler；Described exhaust hood is connected with exhaustor, exhaustor extends to wall box along box top wall, box bottom is extended to again along wall box, then pass from wall box, and extend upwardly in Rose Box, Rose Box is fixed on the sidewall outside casing, is provided with filtrate in Rose Box, and the liquid level of filtrate is higher than exhaustor mouth of pipe height.

Further, being provided with relief valve on the exhaustor of box house, the height of relief valve is higher than the liquid level of filtrate.

Further, described exhaust hood is for falling infundibulate.

Further, the sidewall of the Rose Box above filtrate is provided with the water stopping thresholds of bending downwards.

Further, the open top of described Rose Box, peristome envelope has thin film.

Further, the quantity of described Smoke Sensor is for two.

The invention has the beneficial effects as follows: can the self-extinguishing when in-box electric appliance breaks down on fire, and effectively can prevent insulated case from burst when box house generation arcing fault, and the discharge of toxic and harmful because of fault generation can be reduced.

Accompanying drawing explanation

In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is a kind of structural representation from insulated case of putting out a fire of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.

One as shown in Figure 1 is from putting out a fire insulated case, including casing 1, roof within casing 1 is provided with two exhaust hoods 2, casing 1 roof between two exhaust hoods 2 is provided with foam sprinkler 9, the sidewall of casing 1 is provided with Smoke Sensor 10, it is additionally provided with delay switch, delay switch and Smoke Sensor 10 to be electrically connected in the inside of foam sprinkler 9；Described exhaust hood 2 is connected with exhaustor 3, exhaustor 3 extends to casing 1 sidewall along box top wall, extend to bottom casing 1 along casing 1 sidewall again, then pass from casing 1 sidewall, and extend upwardly in Rose Box 4, Rose Box 4 is fixed on the sidewall outside casing 1, is provided with filtrate 5 in Rose Box 4, and the liquid level of filtrate 5 is higher than the exhaustor mouth of pipe 6 height.

In order to prevent entering inside casing 1 because rocking filtrate 5 in transportation, being provided with relief valve 7 on the exhaustor within casing 1, the height of relief valve 7 is higher than the liquid level of filtrate 5.

In order to strengthen the effect of aerofluxus, described exhaust hood 2 is for falling infundibulate.

In order to reduce filtrate 5 because casing 1 rocks the case mouth on Rose Box 4 and seals the impact produced, the sidewall of the Rose Box 4 above filtrate 5 is provided with the water stopping thresholds 8 of bending downwards.

When using, before casing 1 is installed and put in place, entering casing 1 inside to prevent casing 1 from rocking the filtrate 5 within Rose Box 4, relief valve 7 is closed, and after casing 1 is installed and fixed, opens relief valve 7.Once there is arcing fault in the inside of casing 1, the toxic and harmful produced can sharply expand, by exhaust hood 2 then through exhaustor 3, finally it is drained in filtrate 5, toxic gas is filtered and understands absorption portion gas by filtrate 5, if residual gas still has bigger pressure, thin film bursting can be discharged to the outside of Rose Box 4, meanwhile signal is passed to delay switch after sensing smog by Smoke Sensor 10, delay switch time delay about 4 seconds triggers foam sprinkler 9 by pressurized foaming agent ejection fire extinguishing, the Main Function of delay switch is to prevent the sprinkling foam when moment casing 1 internal high pressure that casing 1 breaks down to be further exacerbated by casing 1 internal pressure, so time delay regular hour rear pressure to be buffered recovers to start fire extinguishing again after normally.

The above, be only the specific embodiment of the present invention, but protection scope of the present invention be not limited thereto, any change expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with claims protection defined.
