The present invention cannot only greatly reduce the amount of water required for extinguishment of the electric vehicle catching fire, but also the non-conductive property of water mist may prevent the high voltage of the lithium-ion battery of electric vehicle from causing damages to surrounding people.

Description

Flat electric vehicle fire extinguishing facilities

The invention relates to a fire-fighting facility, in particular to a planar fire-fighting and fire-fighting system for extinguishing and cooling electric vehicles.

The electricity required to drive electric vehicles, electric motorcycles, etc. is mainly stored in batteries, whether it is a pure electric vehicle (Battery Electric Vehicle, BEV), a hybrid electric vehicle (Hybrid Electric Vehicle, HEV), or a plug-in hybrid electric vehicle. Vehicles (Plug-In Hybrid Electric Vehicle, PHEV) or Fuel Cell Electric Vehicle (FCEV) need to be equipped with batteries that can store and supply large currents. Since the 1990s, rechargeable lithium-ion batteries, with their high energy density and no memory effect, have not only solved the battery life problem of electric vehicles, but also driven the continued development of electric vehicles.

However, the problem with lithium-ion batteries is that when they catch fire due to various reasons such as short circuit, high temperature, or collision... even if the flame outside the lithium-ion battery is extinguished, the high temperature will still accelerate the chemical reaction inside the battery. High temperatures continue to occur, so the lithium-ion battery must continue to cool down until it is completely cooled to avoid re-ignition of the battery and thus prevent disasters.

Therefore, when using the traditional method of water jet irrigation to extinguish fires, extinguishing fires on electric vehicles often requires several times the time and amount of water compared to extinguishing fires on traditional gasoline and diesel vehicles. This is not only time-consuming and water-consuming, but may also affect the response to other disasters. Rescue operations, and more importantly, if you do not remember to cut off the high-voltage cables immediately to cut off the power supply, it is easy for firefighters to receive electric shock. Therefore, when an electric vehicle catches fire, in addition to calling professional firefighters, It is difficult for ordinary people to put out fires on their own without assistance.

In view of the problems existing in the prior art mentioned above, the object of the present invention is to provide a planar electric vehicle fire extinguishing facility that can effectively and safely extinguish the fire of burning electric vehicles.

In order to achieve the above object, the technical means adopted in the present invention is to make a flat electric vehicle fire extinguishing facility include: A peripheral wall extends upward from the ground and surrounds a parking space, with an entrance and exit formed on the peripheral wall; A water mist fire extinguishing equipment, which is installed above the parking space and can spray water mist toward the parking space; A waterproof door assembly is installed close to the entrance and exit, and has a controllable and automatically retractable waterproof door that can selectively close the entrance.

Among the flat electric vehicle fire-extinguishing facilities described above: The ground in the parking space can be recessed to form a transverse groove, and the inner surface of the peripheral wall can be recessed to be formed with two longitudinal guide grooves. The two longitudinal guide grooves are respectively located on both sides of the entrance and exit, and are arranged oppositely. Both ends of the groove are respectively connected to the two longitudinal guide grooves, and sealing strips are respectively embedded in the transverse groove and the two longitudinal guide grooves; When the waterproof door closes the entrance and exit, the peripheral edge of the waterproof door protrudes into the transverse guide groove and the two longitudinal guide grooves, and presses against the sealing strips in the transverse guide groove and the two longitudinal guide grooves.

The planar electric vehicle fire extinguishing and firefighting facility can further include a fire door assembly, which is installed near the entrance and exit. The aforementioned waterproof door assembly is located between the fire door assembly and the entrance and exit. The fire door assembly has A fire door that can be controlled and automatically retracted.

When an electric vehicle parked in the planar electric vehicle fire extinguishing facility of the present invention catches fire, first use the fire door to block fire, smoke and hot air in the parking space, and use the waterproof door to close the entrance and exit of the parking space, and then Then start the water mist generating component to spray water mist on the burning electric vehicle to extinguish the fire and cool down. With the blocking of the waterproof door, the accumulated water formed by the accumulation of water mist will gradually submerge the electric vehicle in the space formed by the peripheral wall and the waterproof door, so that the lithium-ion battery in the electric vehicle can be soaked in the water to continuously cool down. Prevent re-ignition. Since there is no need to continuously pour water on the electric vehicle during the cooling process, the amount of water required to extinguish the electric vehicle fire can be greatly reduced. The non-conductive properties of water mist can also prevent the lithium-ion battery of the electric vehicle from burning. The high voltage will cause harm to the surrounding people. In addition, the high-pressure water mist emitted by the water mist fire extinguishing equipment can also suppress, surround and wash the highly toxic smoke and dust, causing it to fall into the water, thereby protecting the safety of people in the parking space.

The technical means adopted by the present invention to achieve the intended invention purpose will be further described below with reference to the drawings and preferred embodiments of the present invention.

Referring to Figures 1 and 3, the planar electric vehicle fire extinguishing facility of the present invention is arranged on a ground 40 and has a peripheral wall 10, a water mist fire extinguishing equipment 20, a waterproof door assembly 31 and a fire door assembly 32 .

The peripheral wall 10 extends upward from the ground 40 and surrounds a parking space 11 . An entrance 12 is formed on the peripheral wall 10 . The parking space 11 can accommodate at least one electric vehicle 50 . The electric vehicle 50 can be parked through the entrance 12 Entering and exiting the parking space11.

Referring further to FIGS. 5 and 6 , the ground 40 in the parking space 11 is concavely formed with a transverse groove 13 , and the inner surface of the peripheral wall 10 is concavely formed with two longitudinal guide grooves 14 . The two longitudinal guide grooves 14 are concavely formed. They are respectively located on both sides of the entrance and exit 12 and are arranged oppositely. The two ends of the transverse groove 13 are connected to the two longitudinal guide grooves 14 respectively. Seal strips 131 are embedded in the transverse groove 13 and the two longitudinal guide grooves 14 respectively. ,141.

In the preferred embodiment of the present invention, when viewed from above, the peripheral wall 10 is generally U-shaped and surrounds a rectangular parking space 11. The parking space 11 can accommodate an electric vehicle, but the peripheral wall 10 and the parking space 11 are not connected to each other. The shape of the space 11 is not limited to this, and the parking space 11 can also be formed into a type capable of parking multiple electric vehicles or electric motorcycles according to actual needs and design.

The water mist fire extinguishing equipment 20 is installed above the parking space 11 and can spray water mist toward the parking space 11 . Among them, since the water mist is discontinuous water particles and has non-conductive characteristics, it can not only be used to extinguish the fire on the electric vehicle 50, but can also effectively prevent the high voltage of the lithium-ion battery of the electric vehicle 50 from affecting firefighters. Cause harm.

Referring to Figures 1, 3 and 4, the waterproof door assembly 31 is installed close to the entrance and exit 12, and is positioned corresponding to the transverse groove 13 and the two longitudinal guide grooves 14. The waterproof door assembly 31 has a function. The waterproof door 311 is controlled and automatically retractable. The waterproof door 311 can selectively close the entrance and exit 12. When the waterproof door 31 closes the entrance and exit 12, the periphery of the waterproof door 31 protrudes from the transverse groove 13 and the transverse groove 13. The two longitudinal guide grooves 14 press against the transverse groove 13 and the sealing strips 131 and 141 in the two longitudinal guide grooves 14 to prevent liquid from flowing into or out of the parking space 11 from the entrance and exit 12 .

The fire door assembly 32 is installed close to the entrance and exit 12. The waterproof door assembly 31 is located between the fire door assembly 32 and the entrance and exit 12. The fire door assembly 32 has a controllable and automatically retractable fire door 321. The fire door 321 can selectively block between the waterproof door 311 and the electric vehicle 50 .

As shown in Figure 1, during normal use, the waterproof door 311 of the waterproof door assembly 31 and the fire door 321 of the fire door assembly 32 are in a stowed state, so that the entrance and exit 12 of the parking space 11 is open for vehicles to enter and exit.

As shown in Figure 2, when the electric vehicle 50 parked in the flat electric vehicle fire extinguisher of the present invention catches fire, the fire door 321 of the fire door assembly 32 is first driven to extend outward, and the electric vehicle 50 is burned. The generated fire, smoke and heat are blocked in the parking space 11 to ensure that the fire in the parking space 11 will not spread outward; at the same time, the waterproof door 311 of the waterproof door assembly 31 is also driven along the parking space 11 . The longitudinal guide groove 14 moves until it extends into the transverse groove 13 and presses against the sealing strip 131 in the transverse groove 13, thereby closing the entrance and exit 12 of the parking space 11; then the water mist generating assembly 20 can be started. The burning electric vehicle 50 sprays water mist for fire extinguishing and cooling. After the water mist contacts the flame, it will produce cooling and suffocation effects due to evaporation of water vapor, thereby achieving the purpose of suppressing the fire or extinguishing the fire. In addition, when the protection object is a water-soluble flammable liquid, the oxygen dilution effect of water mist can be used to extinguish the fire; for oil fires, water mist particles can be used to form a non-combustible emulsion layer.

Blocked by the waterproof door 311, the accumulated water formed by the accumulation of water mist will gradually submerge the electric vehicle 50 in the space formed by the peripheral wall 10 and the waterproof door 311, allowing the lithium-ion battery in the electric vehicle 50 to soak in the water. The water continues to cool down until the chemical reactions that produce high temperatures inside the lithium-ion battery stop, preventing re-ignition. Among them, since there is no need to continuously pour water on the electric vehicle 50 during the cooling process, the amount of water required to extinguish the fire of the electric vehicle 50 can be greatly reduced, and the non-conductive characteristics of the water mist can prevent the lithium-ion battery of the electric vehicle 50 from being used. High voltage can cause harm to people around you. In addition, the high-pressure water mist emitted by the water mist fire extinguishing equipment can also suppress, surround and wash the highly toxic smoke and dust, causing it to fall into the water, thereby protecting the safety of people in the parking space.
