Automobile automatic fire safety device

technical field

The utility model relates to the protection of means of transportation, in particular to an automatic fire extinguishing device for automobiles, which belongs to the technical field of international patent classification A62C3/07.

Background technique

The oil circuits and circuits of automobile engines are relatively concentrated, and the speed is high during operation. Fires are prone to occur and develop quickly. If they cannot be extinguished in time, they will soon spread to the fuel tank, causing the fuel tank to explode. The consequences are unimaginable. In the prior art, portable dry powder fire extinguishers and portable foam fire extinguishers are mainly used to extinguish automobile fires, but the fire extinguishing effect is limited. Affected by human factors, it is impossible to automatically perceive the fire when a fire occurs, and start the fire extinguishing device to extinguish it. Therefore, it is lagging and unsafe, which will cause unnecessary property losses to the country, units, and individuals, and even cause casualties.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned deficiencies of the prior art, and to provide a timely fire extinguishing, high efficiency and good safety automatic fire safety device for automobiles.

The purpose of this utility model is achieved through the following technical solutions.

An automatic fire safety device for automobiles, which is composed of a fire extinguisher, an oil circuit solenoid valve, a main power switch and a smoke alarm. The fire extinguisher is connected with a nozzle and is provided with a sub-valve, which corresponds to the sensor of the smoke alarm. In the flammable part of the car; the signal output of the smoke alarm is respectively connected to: the sub-valve of the fire extinguisher nozzle, connected to the solenoid valve of the oil circuit through a diode, connected to the main power switch through a diode, and connected to the main power switch through a diode. Fire extinguisher main valve connection.

A temperature-sensing self-starting device—a constant-temperature nozzle is arranged at the nozzle. The temperature-sensing nozzle is a temperature-sensitive glass bubble, and a superconducting heat-sensitive wire is wound outside the temperature-sensitive glass bubble.

The utility model has reasonable structural design and convenient installation and use. When a fire occurs in a car, it can automatically start the fire extinguishing device to put out the fire, automatically cut off the oil circuit and the circuit, avoid the rapid spread of the fire, and has high fire extinguishing efficiency and good safety. A function to protect the safety of the car.

Detailed ways

The automatic fire safety device for automobiles of the utility model is composed of a fire extinguisher 1, an oil circuit solenoid valve 2, a power switch 3, 4 and a smoke alarm 12; the fire extinguisher 1 is connected with nozzles 5, 6, 7, and is provided with a sub-valve F1 , F2, F3, the sub-valves correspond to the sensors of the smoke alarm 12, and are installed in the parts prone to spontaneous combustion of the automobile. The signal output terminal of the smoke alarm 12 is connected to the branch valve of the nozzle of the fire extinguisher 1, connected to the solenoid valve 2 of the oil circuit through a diode, connected to the power switch through a diode, and connected to the main valve of the fire extinguisher through a diode. connect. When the sensor of the smoke alarm detects that there is smoke generated, that is, there is a spontaneous combustion signal of the car, the relay in the smoke alarm is closed and turned on, and a current signal is sent out; the signal is transmitted to the nozzle of the fire extinguisher through a wire. Sub-valve, so that the sub-valve is opened; fire extinguishing is carried out after the main valve of the fire extinguisher is opened. The second is to transmit to the oil circuit solenoid valve 2 through a diode, so that the oil circuit solenoid valve 2 is closed, cut off the combustion power supply, and prevent the fire from spreading along the oil circuit; the third is to transmit to the power switch through a diode, so that the switch is opened and stops. Power supply to prevent the fire from spreading through the wire; the fourth is to transmit it to the main valve of the fire extinguisher through a diode, so that the main valve of the fire extinguisher is opened to implement fire extinguishing.

The utility model has a novel and reasonable design, can detect fire in time and directly and automatically start fire extinguishing, cut off the oil circuit and electric circuit, avoid the spread of fire, and protect the safety of the vehicle. When multiple sets of smoke alarms are connected in parallel, and fire extinguishers are connected with multiple nozzles in parallel, it can be installed in multiple places prone to spontaneous combustion in the car to realize multi-point monitoring and independently implement fire extinguishing tasks. Referring to Fig. 1, the oil solenoid valve 2 is installed on the oil supply pipe, and the main power switch is installed at the output end of the storage battery. Three groups of smoke alarms 12 are provided, and three nozzles 5, 6, 7 are connected to the fire extinguisher 1, which are paired with the smoke sensors of the smoke alarms 12 respectively, and are respectively installed in three places prone to spontaneous combustion of the automobile. The three output signal lines of the smoke alarm 12 are respectively connected with sub-valve F1 of nozzle 5, sub-valve F2 of nozzle 6 and sub-valve F3 of nozzle 7; The third is to connect with the main power switch 3 through diodes D2, D5 and D8 respectively; the fourth is to connect with the power switch 3 of fire extinguisher 1 through diodes D3, D6 and D9 respectively. If spontaneous combustion occurs in any one of the three natural parts, fire extinguishing and treatment can be carried out at that place. If spontaneous combustion occurs in multiple parts, fire extinguishing and treatment can be carried out at the same time. Referring to Fig. 2, the nozzle is provided with a constant temperature nozzle 9, which is made of a temperature-sensitive glass bubble and has the function of automatic temperature sensing; a superconducting heat-sensitive wire 10 is wound on the outside of the temperature-sensitive glass bubble, and the nozzle There is also a pressure indicator 11.
