Description
Technical field
The utility model relates to a kind of vehicle-mounted fire extinguishing system.
Background technology
Automobile also brings a lot of potential safety hazard while bringing convenience to the life of people, and according to investigations, the whole nation has at least up to a hundred vehicle spontaneous combustion events to occur every year, and the reason of self-burning of vehicle mainly contains following four kinds:
1, leak electricity.During engine operation, ignition coil temperature sharply raises, and is easy to produce high pressure electric leakage, causes electric leakage place temperature and constantly raises, the gasoline that ignition engines, carburetor etc. leak, cause spontaneous combustion.
2, leakage of oil.The gasoline leaked is the most direct combustibles, and therefore the maintenance of oil circuit seems abnormal important.
3, electrical equipment inefficacy short circuit.There is melting welding due to contact sintering in some starting switch, starter switch cannot discharge, and causes starter to start (the starter clean boot time is 5S) for a long time, and it is on fire to cause engine to generate heat.
4, contact resistance is excessive, and wiring circuit contact is unreal, and the large generation heat energy of local electric resistive, causes combustible material on fire.
In order to prevent self-burning of vehicle from causing further loss to the personnel of riding and vehicle, traffic requires that vehicle must be furnished with Extinguisher.But the intensity of a fire can spread instantaneously after self-burning of vehicle, by bus personnel are receiving scaring afterwards not as good as adopting fire fighting with fire extinguisher, and therefore, the fire extinguisher of automobile standby is concerning fall flat a lot of spontaneous combustion automobile.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide one to be positioned at engine nacelle, can automatically detect and the vehicle-mounted fire extinguishing system of putting out a fire.
For solving the problem, the utility model is by the following technical solutions: a kind of vehicle-mounted fire extinguishing system, comprise heat detection device, manual actuation of button, extinguishing device and controller, extinguishing device comprises tank body and executing agency, described heat detection device is electrically connected with controller, controller is electrically connected with the executing agency of extinguishing device, it is characterized in that, also comprise motor and base, described extinguishing device is fixed on described base, described base is arranged in engine nacelle by motor is rotating, the executing agency of described extinguishing device comprises magnetic valve, magnetic valve is arranged on the shower nozzle of tank body, described controller drives described motor by motor drive circuit, and controller drives magnetic valve by driving circuit for electromagnetic valve, described manual actuation of button is for controlling the start and stop of described motor and magnetic valve.
Further, the utility model also comprises an indicator lamp, and described indicator lamp is in parallel with magnetic valve.
In order to make the fire extinguishing scope of extinguishing device larger, preferably, the shower nozzle of described tank body is flat mouth.
In order to the Timeliness coverage condition of a fire, further, described heat detection device comprises Smoke Sensor and temperature sensor.
The beneficial effects of the utility model are: its cost is lower, install simple, good reliability; Its base can rotate, and achieves multiple position attack; When automatic control system fault, manually fire extinguishing can be realized by start button.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
As shown in Figure 1, the utility model comprises heat detection device, manual actuation of button, extinguishing device, controller, motor and base.
Extinguishing device comprises tank body and executing agency, tank body adopts existing fire extinguisher tank, at the nozzle place of tank body, executing agency is set, executing agency of the present utility model adopts magnetic valve, controller drives magnetic valve by driving circuit for electromagnetic valve, and the dry powder in tank body is sprayed, and driving circuit for electromagnetic valve is that photo-coupler drives, this drive circuit is the conventional techniques means of those skilled in the art, here repeats no more.In order to make the fire extinguishing scope of extinguishing device larger, preferably, the shower nozzle of described tank body is flat mouth.
In order to the Timeliness coverage condition of a fire, described heat detection device comprises Smoke Sensor and temperature sensor, Smoke Sensor and temperature sensor are electrically connected with controller respectively, like this, even if the temperature in enging cabin does not reach the design temperature of temperature sensor, as long as there is smog to occur, can extinguishing device be opened equally, improve the reliability of this system.
Described extinguishing device is fixed on described base, base is circular, described base is arranged on (motor is fixed on engine nacelle inwall, and the rotating shaft of motor is connected with base, is realized the rotation of base by drive motor) in engine nacelle by motor is rotating.Described controller drives described motor by motor drive circuit, and motor drive circuit is those skilled in the art's known technology means, therefore no longer describes in detail.Described manual actuation of button is arranged on the middle control operating desk of driver's cabin, manual actuation of button is one, control the start and stop of motor and magnetic valve simultaneously, connected mode for manual actuation of button has multiple, can be in parallel with motor drive circuit and driving circuit for electromagnetic valve, or an electric power loop is set on motor and magnetic valve again, manual actuation of button is connected in this loop.
The utility model also comprises an indicator lamp, and described indicator lamp is in parallel with magnetic valve, is driven together with magnetic valve by driving circuit for electromagnetic valve.Indicator lamp is arranged in driver's cabin, and when solenoid valves works, indicator lamp is bright, carries out in order to indicate fire-fighting work.
Operation principle of the present utility model is: after catching fire in enging cabin, in cabin, temperature raises, signal is sent to controller by temperature sensor, even if the temperature in cabin is for reaching temperature sensor setting value, smog in cabin also can be detected by Smoke Sensor, thus signal is sent to controller.After controller receives the signal of heat detection device, drive electromagnetic valve work, extinguishing device starts spray powder fire extinguishing, and meanwhile, controller drive motor works, base rotation, and to the comprehensive injection in cabin, fire extinguishing is without dead angle.
If driver finds that the indicator lamp in driver's cabin is not bright, namely extinguishing device does not work, then manually can carry out the rotation of manual controlled fire-extinguishing device work and base by start button.
The above has made detailed description to preferred embodiment of the present utility model and embodiment by reference to the accompanying drawings; but the utility model is not limited to the above-described embodiment and examples; for those skilled in the art; without departing from the concept of the premise utility; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
