The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Consult Fig. 1, a kind of batteries of electric automobile insulating box automatic fire extinguisher described in the utility model, comprising: on-vehicle battery insulating box 1, sensor 2, data acquisition and signal processing 3, single-chip microcomputer 4, extinguishing device 5, on-vehicle battery is encapsulated in battery thermostat 1, under different ambient temperature conditions, can keep battery operated temperature constant, temperature sensor and smoke detector 2 are arranged on on-vehicle battery, temperature and smog information detected in real time, first data acquisition and signal processing 3 carry out filtering to the temperature and the smoke signal that gather, the Noise and Interference that filtering mixes, then filtered analog signal is amplified and sampled, and temperature and smog value after processing are passed to single-chip microcomputer 4, and with single-chip microcomputer 4 in the temperature and the smog parameter normal range (NR) that have set compare, if overrun, starting warning device reports to the police, single-chip microcomputer 4 sends control signal to electric vacuum pump simultaneously, electric vacuum pump is started working, rapidly by gas vacuum pumping in airtight insulating box, in vacuum, on-vehicle battery stops burning, fire is extinguished fast, the temperature of obtaining when single-chip microcomputer 4 returns to normal range (NR), when atmospheric pressure value drops to a particular value, and INO, air enters insulating box 1, and to guarantee that insulating box 1 opens smoothly, normally closed intake valve cuts out automatically afterwards, and battery thermostat 1 recovers normal work.
Consult Fig. 2, a kind of batteries of electric automobile insulating box automatic fire extinguisher described in the utility model, its workflow is, first the signal of sensor 2 is carried out to acquisition and processing, then will in the temperature of obtaining and smog value input single-chip microcomputer 4, compare with the normal range (NR) of input before, if within normal range (NR), keep original duty, and continue monitor temperature and smog value; If overrun, starts that warning system is reported to the police and extinguishing device 5 is put out a fire.
Consult Fig. 3, a kind of batteries of electric automobile insulating box automatic fire extinguisher described in the utility model, the course of work of normally closed intake valve is, after having put out a fire, in insulating box 1, it is vacuum state, and temperature reduces, when baroceptor and temperature sensor 2 detect battery thermostat 1 internal pressure and temperature and reduce, by signal feedback to single-chip microcomputer 4, with single-chip microcomputer 4 setting pressures and temperature value comparison, when being less than setting value, single-chip microcomputer 4 is controlled normally closed intake valve energising and is opened, in insulating box 1, enter air, when baroceptor detects air pressure and is elevated to certain value, information is fed back in single-chip microcomputer 4, single-chip microcomputer 4 controls normally closed intake valve power-off and cuts out, complete intake process.
A kind of batteries of electric automobile insulating box automatic fire extinguisher described in the utility model, by design batteries of electric automobile insulating box automatic fire extinguisher, can be real-time battery temperature and smokescope be monitored, when having battery fire hazard, can realize the function of intelligent fire fighting, effectively reduce the harm of automobile fire, improve vehicle safety, in the situation that not deviating from the utility model essence, batteries of electric automobile insulating box 1 automatic fire extinguisher 5 can be revised accordingly and is out of shape, but within these corresponding changes all should belong to the claim protection domain under the utility model.
