Abstract

The utility model discloses an automobile automatic fire-fighting device, which comprises a fire extinguisher. The fire extinguisher is provided with an electromagnetic-valve switch which is connected with a controller controlling the close and open of the electromagnetic-valve switch; the controller is connected with a machinery-type sensor or a thermosensitive-type sensor component or a gas-sensitive sensor component through a gate, and controls the close and open of the electromagnetic-valve switch. The utility model adopts the machinery-type sensor or the thermosensitive-type sensor or the gas-sensitive sensor component to receive collision and thermal and gas signals, and can also adopts one of the forms to receive signals and open the fire extinguisher; no matter when the automobile is collided or reaches the limited thermal value, the utility model can ensure the fire extinguisher to open rapidly and automatically puts out the fire, which greatly guarantees the safety of drivers and passengers.

Description

The automobile automatic fire-fighting device

Technical field

The utility model belongs to fire-fighting equipment, relates to a kind of fire plant, particularly a kind of automobile automatic fire-fighting device.

Background technology

Along with the raising day by day of expanding economy and people's living standard, incident is the fast development of highway and the improvement of urban traffic road, and automobile has more been come into family.But because the traffic accident that growth brought of automobile is also being risen year by year, wherein the ratio that accounts for of the collision of automobile in the process of travelling is very big, though present automobile all is provided with safety device, as safety belt, air bag, but the traffic accident that is caused owing to collision also can not be ignored to the disaster that people bring.Because gasoline very easily burns, some serious collisions can cause the gasoline in the car to burn mostly, sometimes because weather conditions are overheated, automobile is under steam because circuit wearing and tearing, aging, short circuit, forging iron all to cause generation burning on fire, and burning often occurs between the engine of automobile the time, the particularity of automobile itself structure in addition, the preceding bonnet of automobile bump or burn after can't open, be not easy in time to put out a fire to save life and property after taking place at fire, passengers inside the car's safety of life and property will be subjected to serious threat.

The fire-fighting equipment that disposes on present most automobile generally is a hand fire extinguisher, when burning or collision take place automobile, because the occupant often is stuck in the car, often can't use hand fire extinguisher.

Three, technology contents

The present invention is the shortcoming that overcomes above-mentioned prior art, provides a kind of when fire takes place, the automobile automatic fire-fighting device that can put out a fire effectively and timely.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of automobile automatic fire-fighting device, comprise a fire extinguisher, be characterized in, fire extinguisher is provided with an electromagnetic valve switch, shut the controller that is connected with the control electromagnetic valve switch at valve opening solenoid, controller by one or door be connected with mechanical sensor, heat-sensitive type senser element and gas-sensitive sensor device.

Other characteristics of the present utility model are that described mechanical sensor adopts mercury tube or tongue tube.

Described controller comprises a controllable silicon, connect controller on the silicon controlled trigger electrode, be connected in parallel to current transformer and oil circuit switch transformer on the silicon controlled major loop, current transformer is connected with electromagnetic valve switch, and oil circuit switch transformer and oil circuit switch interconnect.

In the described fire extinguisher liquid extinguisher or fire foam or powder extinguishing agent.

The utility model adopts mechanical sensor and heat-sensitive type sensor to receive collision and thermal signal, no matter is that automobile bumps or heat arrives limit value, fire extinguisher is opened automatically fast put out a fire, and can protect driver and passenger's safety greatly.

The specific embodiment

The present invention is described in further detail below in conjunction with embodiment that accompanying drawing and inventor provide.

Referring to accompanying drawing, a kind of automobile automatic fire-fighting device, comprise a fire extinguisher 1, it is characterized in that, fire extinguisher 1 is provided with an electromagnetic valve switch 2, on electromagnetic valve switch 2, be connected with the controller 4 of control electromagnetic valve switch, controller 4 by one or door be connected with mechanical sensor 3, heat-sensitive type senser element 5 and gas-sensitive sensor device 6.

Mechanical sensor 3 adopts mercury tube or tongue tube.

Referring to Fig. 3, controller 4 comprises a controllable silicon 401, connect controller 4 on the trigger electrode of controllable silicon 401, be connected in parallel to current transformer 402 and oil circuit switch transformer 403 on the major loop of controllable silicon 401, current transformer 402 is connected with electromagnetic valve switch 2, and oil circuit switch transformer 403 interconnects with the oil circuit switch.

Controller one end can adopt temperature and resistance R2 and equivalent conventional, electric-resistance R1, R3, R4 to constitute bridge circuit is connected to controllable silicon 401 as temperature sensor trigger electrode.When resistance R 2 changed, the output of bridge circuit changed, by R5 with the triode conducting, make the colelctor electrode of triode that signal output be arranged, can make controllable silicon 401 conductings by output current, open electromagnetic valve switch, make the extinguishing chemical ejection in the fire extinguisher 1, resistance R 6 is used for current limliting.

In the fire extinguisher 1 liquid extinguisher or fire foam or powder extinguishing agent.

The utility model can be installed in the interior locus near engine of preceding bonnet of automobile, the power supply of device adopts the direct current on the automobile, mechanical sensor 3 is vertically laid, heat-sensitive type senser element 5 and gas-sensitive sensor device 6 be placed on engine near, be used to monitor the thermal signal and the gas signal of engine.Its operation principle is, if when serious collision takes place automobile, mechanical sensor 3 is knocked down, and the mercury in the sensor makes contacting in the pipe, and electromagnetic valve switch 2 is connected, and opens fire extinguisher 1; If detecting near the temperature of engine, heat-sensitive type senser element 5 surpasses setting value, balance is broken, make its conducting for signal of trigger electrode output of controllable silicon 401, or gas-sensitive sensor device 6 monitors the gas of gasoline above the peculiar smell or the flue gas that set value or plastics catch fire, the current transformer 402 that then is arranged on the controllable silicon passes to electromagnetic valve switch 2 with signal, make electromagnetic valve switch 2 open fire extinguisher 1, oil circuit switch transformer 403 turn-offs oil circuit simultaneously, to prevent that fuel tank from continuing fuel feeding, causes bigger accident.

Certainly, only can make with the mechanical sensor form in the mill, only also can make with heat-sensitive type senser element form or gas-sensitive sensor device, also can adopt compound mode wherein.Fire extinguisher 1 adopts fluid extinguisher or foam annihilator or dry powder extinguisher, can be arranged on the different parts near the space of engine according to the extinguishing chemical that adopts.
