Description

Lifting electric vehicle fire extinguishing facilities

The invention relates to a fire-fighting facility, in particular to a lift-type electric vehicle fire-fighting and fire-fighting facility used 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 lift-type electric vehicle fire extinguishing and firefighting 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 lifting type electric vehicle fire extinguishing facility include: A pit formed by an indentation downward from a ground surface; A lifting platform is installed in the pit. The top of the lifting platform is provided with a bearing plate. The bearing plate can be driven to move upward to be flush with the ground or move downward into the pit. , the load-bearing board can be used for parking electric vehicles; A water mist fire extinguishing equipment is installed above the pit and is positioned corresponding to the lifting platform. The water mist fire extinguishing equipment can spray water mist toward the lifting platform corresponding to the position; A drainage system is installed in the pit, and the drainage system is used to drain the liquid accumulated in the pit.

In the lift-type electric vehicle fire-fighting facility, the drainage system can include at least one drainage channel. The at least one drainage channel is formed in an inner peripheral wall surrounding the pit and connects the pit and the bottom of the pit. Externally, each drainage channel is provided with a channel cover, which can be driven to selectively close the drainage channel.

In the lift-type electric vehicle fire extinguishing facility, the channel cover can be installed on the inner peripheral wall of the pit, and the channel cover can be driven to move laterally, thereby selectively closing the corresponding of drainage channels.

When an electric vehicle parked on the lift-type electric vehicle fire extinguishing facility of the present invention catches fire, the bearing plate of the lifting platform is first driven to move downward, and the electric vehicle is moved into the pit. At the same time, the channel cover of the drainage system The plate is also driven to close the drainage channel, and then the water mist generating component can be started to spray high-pressure water mist on the burning electric vehicle in the pit to extinguish the fire and cool down. In this way, the accumulated water formed by the accumulation of water mist will gradually submerge the electric vehicle in the pit, so that the lithium-ion battery in the electric vehicle can be soaked in the water to continuously cool down to prevent re-ignition. Among them, due to the cooling process There is no need to continuously pour water on the electric vehicle, so the amount of water required to extinguish the electric vehicle fire can be greatly reduced. The non-conductive properties of the water mist can prevent the high voltage of the lithium-ion battery of the electric vehicle from causing harm to 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 lift-type electric vehicle fire-extinguishing facility of the present invention includes a pit 10, a lifting platform 20, a water mist fire-extinguishing equipment 30 and a drainage system 40.

The pit 10 is formed by being concave downward from a ground surface AA. The pit 10 has an inner peripheral wall 11 surrounding the pit 10 .

The water mist fire extinguishing equipment 30 is installed above the pit 10 and is positioned corresponding to the lifting platform 20. The water mist fire extinguishing equipment 30 can spray water mist toward the lifting platform 20 corresponding to the position. 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.

The drainage system 40 is installed in the pit 10 , and the drainage system 40 is used to drain the liquid accumulated in the pit 10 . In a preferred embodiment of the present invention, the drainage system 40 includes at least one drainage channel 41, which is formed in the inner peripheral wall 11 surrounding the pit 10 and connects the pit 10 and the bottom. Outside the pit 10 , each drainage channel 41 is provided with a channel cover 42 . The channel cover 42 can be driven to selectively close the drainage channel 41 so that liquid cannot circulate in the drainage channel 41 .
