Description

Tube type vehicle fire extinguishing device {TUBE TYPE APPARATUS FOR EXTINGUISHING FIRE OF VEHICLE}

The disclosed content is that, for example, when a fire occurs in a vehicle such as an electric vehicle, the vehicle in which the fire occurred is isolated from adjacent vehicles and the fire is extinguished through spraying of fire-fighting water and resulting flooding, thereby extinguishing the vehicle without spreading the fire to adjacent vehicles. A tube-type vehicle that can extinguish fires quickly and easily, and is formed in the form of a closed bulkhead with the upper and lower sides open so that it can be easily installed around a vehicle in fire without the need to move the vehicle in fire with a crane, etc. It is about fire extinguishing devices.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and is not admitted to be prior art by inclusion in this section.

Generally, unlike gasoline vehicles, electric vehicles include a battery, a power conversion device (inverter), and an electric motor.

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

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

Therefore, if a fire occurs in the battery of an electric vehicle due to pressure, overheating, vibration, shock, short circuit, overcharging, or discharging, the separator, which is a safety device, is damaged, causing a thermal runaway phenomenon in which the temperature rises by thousands to tens of thousands of degrees, and the battery is damaged. As the fire has the characteristic of not being extinguished until it is completely burned out, there is no choice but to extinguish the external flames with fire extinguishing water until the fire is completely burned out. Due to the thermal runaway fire characteristics of these electric vehicles, after the fire is activated, It is impossible to extinguish the fire until it is completely destroyed. Additionally, it is known that when a fire occurs in an electric vehicle, more than 10 times more water is required than that required to extinguish a fire in an internal combustion engine vehicle.

As an example of a method to facilitate fire extinguishment of electric vehicles, in Republic of Korea Patent Registration No. 10-1998280 (announced on July 9, 2019), a plurality of lithium-ion batteries are stored in the lower space of the body of an electric vehicle, and are located on one side. An electric vehicle battery unit equipped with multiple nozzles and fire detection sensors; A compressed gas cylinder installed in the electric vehicle and storing compressed inert gas; A plurality of fire extinguisher containers 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 a main pipe and a branch pipe first branching from the main pipe. A compressed gas pipe installed with a compressed gas valve that opens and closes the main pipe; A fire extinguisher pipe at one end connected to the fire extinguishing powder injection port of the fire extinguisher cylinder, at one side of which a branch pipe of the compressed gas pipe is connected to form a T shape, and at the other end connected to each nozzle of the electric vehicle battery unit; 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 a fire detection sensor to inject compressed gas from the gas injection port. .

Republic of Korea Patent Publication No. 10-2021-0057278 (published on May 21, 2021) discloses a volume expansion detection sensor mounted on each cell to detect expansion of a cell of an energy storage system of an electric vehicle, and expansion in the volume expansion detection sensor. Cooling means for spraying a fire extinguishing agent to cool the temperature of the detected cell, fire detection means for detecting a fire inside the energy storage system, and storing the energy to extinguish the fire when the fire detection means detects the fire. A fire extinguishing device for an energy storage system for an electric vehicle is disclosed, which includes a fire extinguishing means for spraying a fire extinguishing agent into the interior of the system.

However, the conventional fire extinguishing device for electric vehicles as described above only prevents battery fires from being activated by detecting and extinguishing battery fires at an early stage, and does not include a component for extinguishing fires in already activated electric vehicles. There is a problem that does not exist.

Meanwhile, in countries such as the United States and Norway, when a fire occurs in an electric vehicle, a method of spraying water on the vehicle, covering the vehicle with a fire blanket folded in water, then lifting the electric vehicle with a crane and submerging it in a water tank is also used.

However, in reality like Korea, for example, if an electric vehicle fire occurs in a place such as an apartment parking lot, it is difficult to apply because it is not easy to access the crane and install a water tank. In particular, the fire of the electric vehicle spreads to adjacent vehicles. There is a problem that can cause a major accident.

It is preferable that the support belt 240 is surrounded on the outer surface of the water tube 210 described above. This support belt 240 serves to reinforce and increase the pressure resistance against water pressure by surrounding and supporting the outer surface of the water tube 210 in the form of a closed loop, and is usually provided with a harness-type coupler at the end. It is formed from a fibrous belt.

To install the support belt 240, a belt ring into which the support belt 240 is inserted is formed on the outer surface of the water tube 210.

Additionally, as shown in FIG. 9, opposing inner sides of the water tube 210 may be connected to each other by webbing 250.

The webbing 250 serves to prevent the water tube 210 from opening outward due to water pressure by forcing the opposing inner sides of the water tube 210 to maintain a certain gap, and is formed as a regular fiber belt. It is possible, but preferably flame retardant.

This webbing 250 may be installed instead of the support belt 240 as shown in FIG. 8, or may be installed together with the support belt 240 as shown in FIG. 9.

Hereinafter, a method of using the tubular vehicle fire extinguishing device 200 according to another embodiment of the disclosed content will be described with reference to FIGS. 6 to 10 as follows.

When the vehicle (3) on fire is confirmed, the vehicle (3) on fire is covered with suffocating fire extinguishing foam to prevent the spread of the fire, and the fire extinguishing operation is carried out in parallel by spraying water toward the vehicle (3) on fire from the outside. When the water tube 210 is installed around the outer circumference of the fire-generating vehicle 3 and the pipe 5 for supplying fire-fighting water is connected to the fire-fighting water inlet 211, the water tube 210 is filled with fire-fighting water. As the water tube 210 surrounds the fire-generated vehicle 3, a water tank in the form of a closed partition is formed around the re-occurring vehicle 3, and at the same time, the water flows toward the fire-generated vehicle 3 through the fire-fighting water outlet 213. Firefighting water is sprayed and supplied, and as shown in FIG. 8, the fire vehicle 3 is submerged in a water tank in the form of a closed partition and the fire is extinguished.

Therefore, for example, when a fire occurs in a vehicle such as an electric vehicle, as shown in FIG. 9, the fire vehicle 3 is adjacent to the vehicle through a water tank in the form of a closed partition formed by a water tube 210 filled with fire-fighting water. The fire is extinguished by isolating it from the vehicle and at the same time submerging the fire-generating vehicle (3) into a water tank in the form of a closed partition by supplying fire-fighting water through the water tube (210), thereby preventing the fire from spreading to adjacent vehicles. It can be evolved quickly and easily.

At this time, the tubular vehicle fire extinguishing device 200 according to another embodiment of the disclosed content has open upper and lower surfaces, so that it can be installed around the fire vehicle 3 without the need to move the fire vehicle 3 with a crane or the like. Since it can be easily installed, fires in vehicles that are on fire can be extinguished more quickly and easily.

In addition, in the case of the tubular vehicle fire extinguishing device 200 according to the disclosed embodiment, a water leak prevention flap 220 is attached to the bottom of the water tube 210, and the inner bottom of the water tube 210 and the water leak prevention flap 220 As the packing material 230 is inserted in between, the firefighting water supplied from the water tube 210 into the water tank in the form of a closed partition can be prevented from leaking to the outside through the water tube 210 and the bottom surface.

In addition, in the case of the tubular vehicle fire extinguishing device 200 according to the disclosed embodiment, the outer surface of the water tube 210 is each surrounded by a support belt 240 and the water tube 210 is connected by a webbing 250. As the inner surfaces are each connected and supported, water pressure resistance characteristics can be increased.

In the above-described tubular vehicle fire extinguishing device 200, when not in use or when use is completed, the firefighting water charged in the water tube 210 is forcibly discharged through, for example, connection to a drain pump, and then discharged as shown in FIG. 10. It is desirable to store it in a rolled-up storage bag (7). This storage bag 7 is preferably provided with a carrying handle.
