Description

The utility model relates to devices for preventing the ignition of a vehicle, preventing the spread of fire.

There are various methods and devices for extinguishing a fire in a car and having varying degrees of effectiveness.

As analogues of the proposed solution were considered:

- automatic fire extinguishing system "MAG", consisting of a fire extinguisher and a cord that responds to an increase in temperature or open flame (website: http: www.autoreview.ru/new_site/yeer2001/n07/tife/Jiere.htm);

- a device containing a fire extinguishing aerosol generator, the resistor of which is supplied with a signal from a fire sensor, while at the same time a signal is sent from the fire sensor to turn off the battery and starter and to block the ignition, while simultaneously shutting off the fuel supply (patent No. 513433 A62C 35/13, RU);

- a device built on the basis of the solution presented above, in which sound and light alarm are output to the car interior (patent No. 78077 А62С 35/13, RU).

An automatic fire extinguishing device on a car according to patent No. 78077, including a fire extinguishing aerosol generator, heat detectors and an alarm system, was selected as a prototype.

An automatic fire extinguishing device on mobile transport and technological vehicles includes an inertial contact sensor, which supplies a control signal to two relays with normally closed contacts, which disconnect the battery ground and starter, as well as block the ignition switch, as a result of which fuel from the gas tank stops flowing or a gas cylinder, a fire detector (sensor) that turns off the vehicle’s electrical system and supplies a control signal to the extinguishing aerosol generator.

The disadvantages of the prototype: a fire extinguishing aerosol generator (GOA) contains a squib, which is unacceptable in a vehicle with people;

the aerosol is evenly distributed throughout the entire space (engine compartment, cab, trunk, etc.), and is not directed to potentially hazardous areas of ignition. In addition, it seems that the proposed system is unnecessarily complicated, which reduces the reliability of the fire extinguishing system. In addition, a failure in any of the elements of the fire extinguishing system may cause a cutoff in the supply of fuel and electricity while the car is moving.

The purpose of the proposed technical solution is the localization of the resulting fire and its complete cessation.

This goal is achieved by the fact that in the engine compartment place a fire-extinguishing aerosol generator, which is connected by pipelines to areas of increased risk of fire. In this case, the pipelines are connected to the aerosol generator via electrovalves, which are electrically connected to the fire detector, as well as to the valve display and joystick.

Simultaneously with the supply of pipelines to the fire zones in the engine compartment, the pipelines are connected to the brake devices of the car.

The automatic device for extinguishing a fire in a car (in a car) is shown in Fig. 1 and includes: a fire extinguishing aerosol generator 1, a nozzle in the form of a comb 2 for connecting pipelines 3 to it for supplying a fire extinguishing aerosol to fire hazard zones, electric valves 4, fire detectors (sensors ) 5, on / off switch (joystick) 6, display 7 in the car cabin, power supply (current) 8.

The device operates as follows.

In the event of a fire or when the temperature rises in the zone of increased fire hazard, a fire detector 5 electrically connected to the vehicle’s battery (8) receives an electric signal to the electrovalves 4 and the extinguishing aerosol from the generator 1 through the nozzle 2 and the pipe 3 enters the ignition zone (possible fire) . At the same time, the electric valves for opening the extinguishing agent supply pipelines are connected to the on-off switch installed in the car interior and are connected to the manual control device (joystick), and fire detectors are connected to the display in the car.

When the driver is inside the car and the display (7) shows signs of fire (fire signal), the extinguishing operation can be carried out from the passenger compartment using the joystick control (6).
