It relates to a tubular vehicle fire extinguishing device that allows the fire of a fire to be quickly and easily extinguished, and more specifically, the bottom surface is formed open so that it is easily installed around the fire vehicle without the need to move the vehicle with a crane or the like It relates to a tubular vehicle fire extinguishing device capable of quickly and easily extinguishing a fire by submerging a fire-producing vehicle through the supply of fire-fighting water.

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.

For example, in the event of a fire in a vehicle such as an electric car, the fire in the vehicle is isolated from the adjacent vehicle and the fire is extinguished through the supply of fire-fighting water and subsequent flooding. It is intended to provide a tubular vehicle fire extinguishing device that can be quickly and easily extinguished.
