Abstract

The utility model relates to an automatic fire extinguisher of a vehicular engine housing, which is composed of temperature sensors, a singlechip micro-computer, a gas guide pipe, program control gas valves and a gas storage cylinder, wherein compressed liquid carbon dioxide is filled in the gas storage cylinder; the gas guide pipe is connected onto the cylinder mouth of the gas storage cylinder and extends to flammable parts in the engine housing from the cylinder mouth; a plurality of exhaust holes are arranged on the gas guide pipe; the program control gas valves are arranged on the exhaust holes; the temperature sensors corresponding to the program control gas valves on the exhaust holes are arranged near the exhaust holes; the signal input end of the program control gas valve is connected with the signal output end of the singlechip micro-computer; and the signal output end of the temperature sensor is connected with the signal input end of the singlechip micro-computer. According to the utility model, the singlechip micro-computer operating a monitoring program obtains temperature values measured by various temperature sensors in real time; and in addition, in the event of detecting that the measured temperature value is up to or beyond a pre-set value, the program control gas value corresponding to the temperature sensor is opened, so that carbon dioxide is ejected to extinguish fire and cool.

Description

Vehicle startup cabin Automatic Fire Extinguisher

Technical field

A kind of vehicle startup cabin Automatic Fire Extinguisher, especially in vehicle startup cabin certain or the many places temperature meet or exceed when setting value and automatically start the device of fire-extinguishing function concurrently.

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, when this vehicle startup cabin Automatic Fire Extinguisher certain or many places temperature in the vehicle startup cabin being detected meet or exceed setting value, automatically start fire-extinguishing function concurrently and put out a fire in the corresponding position and lower the temperature.

the technical scheme that its technical problem that solves the utility model adopts is: this vehicle startup cabin Automatic Fire Extinguisher is by temperature sensor, single-chip microcomputer, wireway, program control air valve and gas bomb form, the compressed liquid carbon dioxide is housed in gas bomb, wireway is connected on the bottleneck of gas bomb, and extend to each inflammable parts in engine bin from bottle mouth position, wireway is provided with a plurality of steam vents, steam vent is provided with program control air valve, the steam vent side is provided with the temperature sensor corresponding with the program control air valve on this steam vent, the signal input part of program control air valve is connected with the signal output part of single-chip microcomputer, the signal output part of temperature sensor is connected with the signal input part of single-chip microcomputer.

This vehicle startup cabin Automatic Fire Extinguisher uses the storage battery power supply of vehicle, and program control air valve is for can accept the monolithic processor controlled air valve that opens and closes operation.

Moving the temperature value that each temperature sensor of single-chip microcomputer Real-time Obtaining of monitoring facilities records, when it detects the temperature value that records and meets or exceeds the sensor of setting value, namely control the program control air valve corresponding with this temperature sensor and open, the ejection carbon dioxide is put out a fire and lowers the temperature.

The beneficial effects of the utility model are, this vehicle startup cabin Automatic Fire Extinguisher is about on fire or just can in time start fire-extinguishing function concurrently when on fire in the vehicle startup cabin, 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 the utility model structural representation.

(1) wireway in figure, (2) temperature sensor, (3) program control air valve, (4) gas bomb.

The specific embodiment

this vehicle startup cabin Automatic Fire Extinguisher is by temperature sensor (2), single-chip microcomputer, wireway (1), program control air valve (3) and gas bomb (4) form, the compressed liquid carbon dioxide is housed in gas bomb, wireway is connected on the bottleneck of gas bomb, and extend to each inflammable parts in engine bin from bottle mouth position, wireway is provided with a plurality of steam vents, steam vent is provided with program control air valve, the steam vent side is provided with the temperature sensor corresponding with the program control air valve on this steam vent, the signal input part of program control air valve is connected with the signal output part of single-chip microcomputer, the signal output part of temperature sensor is connected with the signal input part of single-chip microcomputer.

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.
