The fire of the can be quickly and easily extinguished, the bottom surface is formed open and can be easily installed around the fire vehicle without the need to move the fire vehicle with a crane, etc., and through the injection of air in advance, the fire vehicle It relates to a tubular vehicle fire extinguishing device that can be easily transported and installed around the circumference, and which allows fire-fighting water to be quickly and easily injected into a fire vehicle due to pre-injected air when fire-fighting water is injected.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and inclusion in this section is not an admission that it is prior art.

In general, electric vehicles, unlike gasoline vehicles, include a battery, a power converter (inverter), and an electric motor.

Among them, the battery is an energy storage device that stores electricity for driving an electric motor and driving a vehicle, and a power converter is a device that converts electrical energy of a battery to generate a necessary driving force. It is rotated and driven by the converted electric energy to drive the electric vehicle.

These electric vehicles have the advantage of being eco-friendly, but have a fatal disadvantage that is difficult to extinguish fire. Batteries, which are energy storage devices applied to electric vehicles, are densely arranged with high-capacity battery cells in accordance with space and weight constraints and installed in a sealed form to minimize physical impact from the outside. Evolution is relatively difficult.

Therefore, when a fire occurs in the battery of an electric vehicle due to pressure, overheating, vibration, shock, short circuit, overcharging, discharging, etc., the separator, which is a safety device, is damaged, accompanied by a thermal runaway phenomenon in which the temperature rises to thousands to tens of thousands of degrees. As the fire does not go out until it is completely burned out, there is no choice but to extinguish the fire that appears outside with fire extinguishing water until it is completely burned out. It is impossible to extinguish the fire until it burns down. In addition, it is known that when a fire occurs in an electric vehicle, more than 10 times more water is required than the water required to extinguish a fire in an internal combustion locomotive.

As an example of a method for facilitating fire extinguishing of an electric vehicle, Korean Patent Registration No. 10-1998280 (published on July 9, 2019) has a plurality of lithium-ion batteries stored in the lower space of the vehicle body of the electric vehicle, and on one side An electric vehicle battery unit in which a plurality of nozzles and fire detection sensors are installed; a compressed gas cylinder installed in the electric vehicle and in which inert gas is compressed and stored; a plurality of fire extinguishing cylinders installed in the electric vehicle and storing fire extinguishing powder; It consists of one main pipe connected to the gas injection port of the compressed gas cylinder and branch pipes branching from the main pipe and having the same number as the number of fire extinguisher cylinders, and branching from the main pipe and the main pipe first. A compressed gas pipe in which a compressed gas valve located between the main pipe and opening and closing the compressed gas pipe is installed; One end is connected to the fire extinguishing powder injection port of the fire extinguisher cylinder, the branch pipe of the compressed gas pipe is connected to one side to form a T shape, and the other end is connected to each nozzle of the electric vehicle battery unit Fire extinguisher pipe; and a control unit that keeps the compressed gas valve closed in normal times and opens the compressed gas valve when a fire detection signal is received from the fire detection sensor so that compressed gas is sprayed from the gas nozzle. .

Korean Patent Publication No. 10-2021-0057278 (published on May 21, 2021) discloses a volume expansion sensor mounted on each cell in order to detect the expansion of a cell of an energy storage system of an electric vehicle, and an expansion in the volume expansion sensor. A cooling means for injecting an extinguishing agent to cool the temperature of the detected cell, a fire detection means for detecting a fire inside the energy storage system, and the energy storage for extinguishing a fire when a fire is detected by the fire detection means. Disclosed is a fire extinguishing device of an energy storage system for an electric vehicle, comprising a fire extinguishing means for injecting a fire extinguishing agent into the system.

However, as described above, the conventional fire extinguishing device of an electric vehicle detects and extinguishes a fire in a battery at an early stage so as to prevent a fire in a battery from being activated, and does not include a configuration for extinguishing a fire in an already activated electric vehicle. There is a problem that doesn't.

On the other hand, in countries such as the United States and Norway, in the event of a fire in an electric vehicle, water is sprinkled on the vehicle, then the vehicle is covered with a fire blanket folded in water, and then the electric vehicle is lifted with a crane and submerged in a water tank.

However, in reality such as Korea, in the case of a fire in an electric vehicle in a place such as a parking lot of an apartment, it is difficult to apply it because it is not easy to access a crane and install a water tank. There is a problem that can cause a major accident.
