Abstract
The utility model discloses an automatic fire-fighting device which can automatically detect around condition and inject fire retardant, comprising a casing with an injector, a fire retardant in the casing, a film covering on the injector which can satisfy the preset voltage endurance, and a blaster fixed in the casing. The utility model is characterized in that the blaster is substantially composed of a film which can satisfy the preset voltage endurance, a gas generator and an igniter covered in the film, the igniter is connected to the output of control circuit, and at least one sensor is connected to the signal input of control circuit. In application, the utility model can be mounted on site, and when the sensor detects the dangerous condition, the igniter will blast the gas generator, thereby generating much high-pressure gas, breaking sealed film and injecting out the fire retardant, and extinguishing the fire hazard.
Description
Technical field
The utility model relates to and a kind ofly can detect surrounding environment, and the automatic automatic fire extinguisher of spray fire extinguishing agent automatically.
Background technology
In recent years, in industry, the growing growth of communications, each electric appliances or industrial malignant fire accident also happen occasionally, and bring heavy losses for country, enterprise.And existing fire-extinguishing apparatus, particularly traditional hand extinguisher, because the restriction that needs the special messenger to operate and be subjected to putting position, in case breaking out of fire often can not in time be found and be stamped out a fire.For example, the easy fire position of automobile generally all concentrates in the engine nacelle, and the motorbus cabin is at body tail, in case the driver of catching fire is difficult for realizing usually have the accident of vehicle spontaneous combustion to take place, gently then car is ruined, heavy then people dies.Existing vehicle is typically equipped with hand extinguisher, but often finds that the condition of a fire is late, promptly uses hand extinguisher to extinguish the blaze after waiting discovery, vehicle also major part burn.As some buildings, though fire fighting device is arranged, the intensity of a fire is big when also having the discovery condition of a fire, the difficulty of putting out a fire to save life and property in addition.Positions such as same cable duct, distribution box are also on fire easily, but general unmanned guard has caused very big loss when finding the condition of a fire.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of and be installed in required occasion, can detect surrounding environment automatically, and the automatic fire extinguisher of spray fire extinguishing agent automatically.
For achieving the above object, the concrete technical scheme that the utility model adopts is: described automatic fire extinguisher, mainly comprise: a housing that is provided with jet, be placed with extinguishing chemical in the housing, the film that withstand voltage satisfied setting requires is sealed on jet, also is set with initiator in housing; The film that initiator is mainly required by withstand voltage satisfied setting, gas-forming agent and the ignition device that is coated in the film are formed, ignition device is connected with the output of control circuit device, and at least one sensor is connected with the signal input part of control circuit device.
A kind of further technical scheme of the utility model is: be fixed with a mounting bracket in the outside of housing, the control circuit device is installed in the mounting bracket.
Above-mentioned control circuit device mainly is made of sensor signal input circuit device, logic comparator circuit device, execution output circuit device and power supply; The output of sensor signal input circuit device is connected with the input of logic comparator circuit device, and the output of logic comparator circuit device is connected with the input of carrying out the output circuit device.
Above-mentioned sensor can be temperature sensor or Smoke Sensor.
Above-mentioned housing is steel, the housing that is spurting.As being the housing of horn shape or parabolic shape.
The utility model has the advantages that: described automatic fire extinguisher can be installed in required place, because sensor can be responded to the variation of ambient temperature or smog etc. constantly, in case detect dangerous situation, the control circuit device just can make ignition device send spark, thereby ignite gas-forming agent rapidly, moment produces a large amount of gases at high pressure, and breaks through the film that seals and with the extinguishing chemical ejection, realize the purpose that stamps out a fire.
Description of drawings
Fig. 1 is the structural representation of automatic fire extinguisher described in the utility model;
Fig. 2 is the circuit block diagram of the control circuit device described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As shown in Figure 1, in the present embodiment, described automatic fire extinguisher mainly comprises: a housing 9 that is provided with jet, be placed with extinguishing chemical 3 in the housing 9, and the film 2 that withstand voltage satisfied setting requires is sealed on jet, also is set with initiator in housing 9; The film 4 that initiator is mainly required by withstand voltage satisfied setting, gas-forming agent 5 and the ignition device 6 that is coated in the film are formed, ignition device 6 is connected with the output of control circuit device 7, and at least one sensor 1 is connected with the signal input part of control circuit device 7.Be fixed with a mounting bracket 8 in the outside of housing 9, control circuit device 7 is installed in the mounting bracket 8.In actual use, described housing 9 can be made and is spurting by the steel material---as: can be the horn shape of steel or parabolic shape etc.; Described extinguishing chemical 3 can be an ammonium phosphate powder extinguishing agent; Described gas-forming agent 5 mainly is by pin acid potassium, sell sour sodium, the magnesium powder is formulated; The film 4 that film 2 that described withstand voltage satisfied setting requires and withstand voltage satisfied setting require all can adopt the aluminium film; Described sensor can be temperature sensor or Smoke Sensor, and can dispose a plurality of sensors according to the needs of field of employment.As shown in Figure 2, described control circuit device 7 mainly is made of sensor signal input circuit device, logic comparator circuit device, execution output circuit device and power supply, and described power supply can be selected dry cell or vehicle power etc. for use; These circuit arrangements of above-mentioned formation control circuit device 7 are all commonly used in sensor control field, the circuit engineering of maturation, so be not described in detail in the utility model.
The operation principle of the automatic fire extinguisher of said structure is: at first this device is installed in required place, and the jet of housing 9 is aimed at inflammable position, again sensor 1 is arranged in suitable place.When pyrophoricity accident takes place when, sensor 1 will detect these abnormal conditions, control circuit device 7 is according to sensor 1 detected signal, by logic relatively after, make ignition device 6 igniting by carrying out the output circuit device, ignite gas-forming agent 5 rapidly, in aluminium film 4, will produce a large amount of gases moment, the pressure moment sharp increase in the aluminium film 4, because the requirement of withstand voltage of aluminium film 4 is can be predefined, thereby when its internal pressure during greater than aluminium film 4 withstand voltage, aluminium film 4 will be broken through, and is same, aluminium film 2 also can be broken through, final gases at high pressure will spray housings 9 with extinguishing chemical 3, and spray to the place of appointment, realize the purpose of fire extinguishing.
