Description

Tubular vehicle fire extinguishing device

The disclosed content is that, for example, when a fire occurs in a vehicle such as an electric vehicle, the fire in the vehicle is quickly extinguished without spreading to the outside through the spraying of fire-fighting water and the resulting flooding as it is installed to surround the vehicle in question. The bottom surface is open so that it can be quickly and easily installed around the fire vehicle, so there is no need to lift the fire vehicle using a crane or the like and move it into a separate fire extinguishing tank. This relates to a tubular vehicle fire extinguishing device that allows a water tank to be formed in a short period of time.

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.

For example, in the event of a fire in a vehicle such as an electric vehicle, it is installed to surround the vehicle where the fire occurred, so that the fire in the vehicle where the fire broke out can be extinguished quickly without spreading to the outside through the spraying of firefighting water and the resulting flooding. We would like to provide a tube-type vehicle fire extinguishing device.

In addition, the bottom is open and can be quickly and easily installed around the fire vehicle, so there is no need to lift the fire vehicle using a crane or move it into a separate fire extinguishing water tank. It is a closed water tank surrounding the fire vehicle. The aim is to provide a tube-type vehicle fire extinguishing device that can be formed in a short period of time, enabling a more rapid response to vehicle fires.

Hereinafter, the configuration and effects of the preferred embodiment will be examined with reference to the attached drawings. For reference, in the drawings below, each component is omitted or schematically shown for convenience and clarity, and the size of each component does not reflect the actual size. In addition, the same reference numerals refer to the same components throughout the specification, and reference numerals for the same components in individual drawings will be omitted.

The tubular vehicle fire extinguishing device 100 according to an embodiment of the disclosed content isolates the fire-generating vehicle 3 from adjacent vehicles when a fire occurs in a vehicle such as an electric vehicle, sprays fire-fighting water, and causes flooding. As shown in FIGS. 1 to 4, the lower water is formed in a closed form to surround the fire-generating vehicle 3 and has a charged water inlet 111 on the outside through which the charged water is injected. It is integrally connected to the upper part of the tube 110 and the lower water tube 110, is formed in a closed form to surround the fire vehicle 3, and stands up according to the filling of the fire-fighting water sprayed on the fire vehicle 3. The upper skirt 120 is provided on the top of the upper skirt 120 and the top of the upper skirt 120 is levitated according to the filling of the fire-fighting water sprayed on the fire vehicle 3. It includes a buoyancy material 130 that allows it to stand up.

Here, the lower water tube 110 forms a closed tube, such as a rectangle, to surround the lower side of the fire vehicle 3, and is formed as a tube so that air or fire-fighting water can be filled inside. .

In addition, the lower water tube 110 preferably has a cross-section of various shapes such as circular, oval, and trapezoid when filling the filled water. For example, it is preferably made of a waterproof fabric such as neoprene, and at least the inner side is flame retardant. It is preferable that it is treated or non-combustible.

A charged water injection port 111 through which charged water is injected is formed on the outside of the lower water tube 110. This charging water inlet 111 allows the pipe 5 for supplying fire-fighting water to be connected, and has a similar configuration to a normal faucet connection port.

In addition, the charged water injection port 111 is preferably formed on the lower side of the outer side of the lower water tube 110, and is configured to be open and closed by a separate cap, so that the pipe 5 can be connected by removing the cap only when necessary. It is desirable to have

An air injection outlet 113 through which air is injected or discharged may be additionally provided on the outside of the lower water tube 110. In a state in which the fire-fighting water charged in the lower water tube 110 is forcibly drained, the lower water tubes 110 themselves stick together, so that when fire-fighting water is injected in the future, the charged water flows into the lower water tube through the charged water injection port 111. There are cases where it is not properly injected into (110). In the disclosed content, air is pre-injected into the lower water tube 110 through the air injection outlet 113 prior to injection of the filled water, so that the lower water tube 110 is connected to each other. In a non-stick state, the charged water can be injected more effectively. Additionally, the air injection outlet 113 allows the air pre-charged in the lower water tube 110 to be exhausted when the charged water is injected through the charged water inlet 111.

The air injection outlet 113 is preferably formed on the upper side of the outer side of the lower water tube 110, and is preferably formed to be openable and closed by a separate stopper so that it can be opened only when necessary.

The upper skirt 120 is integrally connected to the upper part of the aforementioned lower water tube 110. The upper skirt 120 is closed along the upper circumference of the lower water tube 110 to surround the upper side of the fire vehicle 3 while standing up due to buoyancy as the fire-fighting water is charged to the fire vehicle. is formed

The upper skirt 120 is attached to the inside based on the vertical center line of the lower water tube 110 as shown in FIG. 2 to more easily support the water pressure caused by fire-fighting water, and slopes inward toward the top. It is preferable that it extends, but depending on the embodiment, it may be attached on the vertical center line of the lower water tube 110 or outside of the vertical center line of the lower water tube 110.

In addition, the upper skirt 120 is preferably made of a waterproof fabric of the same material as the lower water tube 110, such as neoprene, and at least the inner side is preferably treated with flame retardant or non-combustible treatment.

A buoyancy material 130 is provided at the top of the above-described upper skirt 120. The buoyancy material 130 serves to cause the upper skirt 120 to stand by levitating the upper end of the upper skirt 120 through buoyancy according to the charging of fire-fighting water sprayed to the fire vehicle.

This buoyancy material 130 can be formed of ordinary synthetic resin foam. In this case, the buoyancy material 130 may be inserted and fixed along the entire upper circumference of the above-described upper skirt 120, or may be inserted and fixed in multiple pieces spaced apart along the upper circumference of the above-described upper skirt 120. In addition, the buoyancy material 130 may be built inseparably at the top of the above-described upper skirt 120, and depending on the embodiment, may be formed so that it can be inserted into the top of the upper skirt 120 when necessary. .

Additionally, the buoyancy material 130 can be formed in the form of an air tube at the top of the upper skirt 120.

The leak prevention flap 140 is pressed by the water pressure of the water charged in the lower water tube 110 and comes into close contact with the floor, preventing fire-fighting water from leaking to the outside through between the bottom and the bottom of the lower water tube 110. It plays a role.

In addition, the water leak prevention flaps 140 are arranged in multiple numbers connected to each other along the bottom circumference of the lower water tube, and are preferably connected to each other along the zigzag connection line 141 as shown in the partial bottom view of FIG. 1. . In this case, as the joint portion of the water leak prevention flap 140 is connected in a zigzag shape, water leakage through the joint portion can be prevented to a minimum.

This water leak prevention flap 140 can be formed of a regular waterproof fabric or waterproof mat having a certain thickness.

As shown in FIG. 2, a packing material 150 may be inserted between the inner bottom of the aforementioned lower water tube 110 and the water leak prevention flap 140. The packing material 150 seals the space between the inner bottom of the lower water tube 110 and the anti-leakage flap 140, so that the water pressure caused by firefighting water is directly directed to the joint area between the lower water tube 110 and the anti-leakage flap 140. By preventing pressure, it serves to prevent rupture of the joint area of the leak prevention flap 140 and resulting water leaks. It can be formed as a bar-shaped packing made of a material such as silicone or urethane, and can also be formed in the form of an air tube. .

It is desirable to have a wedge-shaped cross-section.

In addition, instead of the above-mentioned packing material 150, there is a packing material on the inner bottom of the lower water tube 110 or the inner upper surface of the leakage prevention flap 140 that expands upon injection of air or water and takes on the role of the packing material 150. The tube body may be installed.

The inner upper surface of the aforementioned lower water tube 110 and the inner surface of the upper skirt 120 are connected by a reinforcing flap 160. The reinforcement flap 160 reinforces the connection between the lower water tube 110 and the upper skirt 120 by allowing the upper skirt 120 to be more firmly connected to the inner upper surface of the lower water tube 110. Even when water pressure from fire-fighting water is applied, the upper skirt 120 is supported so that it does not spread outward any further, so that the pressure resistance characteristics can be increased, and a plurality of them are arranged spaced apart along the inner circumference of the upper skirt 120.

The lower end of the reinforcement flap 160 extends downwardly curved toward the inside so as to correspond to the inner upper surface of the lower water tube 110, and preferably has a shape that converges toward a point on the inner side of the upper skirt 120 toward the top. do.

This reinforcement flap 160 is preferably made of the same waterproof fabric as the lower water tube 110 and the upper skirt 120, such as neoprene.

It is preferable that the support belt 170 is surrounded by the outer surface of the above-described lower water tube 110 and the outer surface of the upper skirt 120. This support belt 170 surrounds and supports the outer surface of the lower water tube 110 and the outer surface of the upper skirt 120 in a closed loop, thereby reinforcing and increasing the internal pressure characteristics against the water pressure caused by fire-fighting water. By doing this, it is formed as a conventional fiber belt provided with a harness-type coupler at the end.

To install the support belt 170, a belt ring into which the support belt 170 is inserted is formed on the outer surface of the lower water tube 110 and the outer surface of the upper skirt 120.

Additionally, as shown in FIG. 4, the facing inner surface of the lower water tube 110 and the facing inner surface of the upper skirt 120 may be connected to each other by webbing 180.

The webbing 180 forces the facing inside of the lower water tube 110 to maintain a certain gap and forces the facing inside of the upper skirt 120 to maintain a certain gap, so that the lower water tube 110 can be used for firefighting water. It serves to prevent the belt from spreading outward due to water pressure, and can be formed as a regular fiber belt, but it is preferable that it is flame retardant treated.

This webbing 180 may be installed instead of the support belt 170, or may be installed together with the support belt 170 as shown in FIG. 4.

Hereinafter, a method of using the tubular vehicle fire extinguishing device 100 according to an embodiment of the disclosed content will be described with reference to FIGS. 1 to 5 as follows.
