Abstract
The utility model provides a vehicle engine cabin automatic fire extinguisher based on a thermal fuse, comprising a thermal fuse, a normally closed relay, a solenoid valve and a gas bomb, wherein the thermal fuse is a conductor with a low fusion point, an insulating layer is wrapped on the outer surface of the thermal fuse, the thermal fuse is wound on the inflammable part in the vehicle engine cabin, the thermal fuse is connected to the input loop of the normally closed relay, the solenoid valve is connected to the output loop of the normally closed relay, the solenoid valve is mounted on the opening of the gas bomb, and compressed liquid carbon dioxide is stored in the gas bomb. The storage battery of the vehicle is used for supplying power to the vehicle engine cabin automatic fire extinguisher based on the thermal fuse, the output loop of the normally closed relay is disconnected after the input loop of the normally closed relay is closed and electrified, and the output loop of the normally closed relay is closed after the input loop of the normally closed relay is disconnected. After the thermal fuse is fused, the input loop of the normally closed relay is disconnected and the output loop of the normally closed relay is immediately closed, the solenoid valve connected with the output loop of the normally closed relay is opened, and the compressed liquid carbon dioxide stored in the gas bomb is sprayed out from the opening of the gas bomb for fire extinguishing and cooling of the vehicle engine cabin.
Description
Technical field
A kind of vehicle startup cabin Automatic Fire Extinguisher based on thermo-fuse especially is about to the on fire or firm device that automatically starts fire-extinguishing function concurrently when on fire in the vehicle startup cabin.
Background technology
There is no automatic fire extinguisher in existing vehicle startup cabin, in the engine bin that, long-time driving high because of temperature, collision or circuit, oil circuit are aging etc. causes, the accident of spontaneous combustion happens occasionally, can vehicle be burnt fully in the very short time after spontaneous combustion in engine bin, even jeopardize occupant's life security, use existing fire extinguisher usually to have little time to extinguish the blaze, vehicle is scrapped by burning.
Summary of the invention
In order to overcome the deficiency that there is no automatic fire extinguisher in existing vehicle startup cabin, the utility model provides a kind of vehicle startup cabin Automatic Fire Extinguisher based on thermo-fuse, should be about to based on vehicle startup cabin Automatic Fire Extinguisher of thermo-fuse on fire or just when on fire in the vehicle startup cabin, and automatically start fire-extinguishing function concurrently the vehicle startup cabin is put out a fire and lowered the temperature.
The technical scheme that its technical problem that solves the utility model adopts is: should be comprised of thermo-fuse, normally closed relay, electromagnetic gas valve and gas bomb based on the vehicle startup cabin Automatic Fire Extinguisher of thermo-fuse, thermo-fuse is the lower conductor of fusing point, its outer surface is wrapped in insulating barrier, it is looped around the inflammable position in the vehicle startup cabin, thermo-fuse is connected to the input circuit of normally closed relay, electromagnetic gas valve is connected to the output loop of normally closed relay, electromagnetic gas valve is arranged on the gas storage bottleneck, is storing the compressed liquid carbon dioxide in gas bomb.
Should use based on the vehicle startup cabin Automatic Fire Extinguisher of thermo-fuse the storage battery power supply of vehicle, normally closed relay its output loop after the closed energising of its input circuit disconnects, after its input circuit opens circuit, its output loop is closed, and electromagnetic gas valve is opened after the closed energising of output loop of normally closed relay.
Thermo-fuse runs into high temperature melting and has no progeny, the input circuit of normally closed relay opens circuit, and its output loop is closed immediately, and the electromagnetic gas valve that is connected to its output loop is opened, compressed liquid carbon dioxide in gas bomb is put out a fire and lowers the temperature the vehicle startup cabin from the ejection of gas storage bottleneck.
The beneficial effects of the utility model are, this vehicle startup cabin Automatic Fire Extinguisher is simple in structure, with low cost, the vehicle startup cabin be about on fire or just can in time put out a fire and lower the temperature when on fire, and can to causing any adverse effect in engine bin, can effectively not prevent the generation of incidents of spontaneous combustion in the vehicle startup cabin after the startup fire-extinguishing function concurrently.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. thermo-fuses in figure, 2. normally closed relay, 3. electromagnetic gas valve, 4. gas bomb, 5. power interface.
The specific embodiment
Should be formed by thermo-fuse (1), normally closed relay (2), electromagnetic gas valve (3) and gas bomb (4) based on the vehicle startup cabin Automatic Fire Extinguisher of thermo-fuse, thermo-fuse is the lower conductor of fusing point, its outer surface is wrapped in insulating barrier, it is looped around the inflammable position in the vehicle startup cabin, thermo-fuse is connected to the input circuit of normally closed relay, electromagnetic gas valve is connected to the output loop of normally closed relay, electromagnetic gas valve is arranged on the gas storage bottleneck, is storing the compressed liquid carbon dioxide in gas bomb.
Should use based on the vehicle startup cabin Automatic Fire Extinguisher of thermo-fuse the storage battery power supply of vehicle, normally closed relay its output loop after the closed energising of its input circuit disconnects, after its input circuit opens circuit, its output loop is closed, and electromagnetic gas valve is opened after the closed energising of output loop of normally closed relay.
Thermo-fuse runs into high temperature melting and has no progeny, the input circuit of normally closed relay opens circuit, and its output loop is closed immediately, and the electromagnetic gas valve that is connected to its output loop is opened, compressed liquid carbon dioxide in gas bomb is put out a fire and lowers the temperature the vehicle startup cabin from the ejection of gas storage bottleneck.
Above disclosed be only the application's a specific embodiment, but the application is not limited thereto, the thinkable variation of any those skilled in the art all should fall in the application's protection domain.
Claims (2)
