Description

Technical Field

[0001] The present invention relates to the field of fire protection technology, and in particular to an automatic fire extinguishing system for charging and parking areas of new energy vehicles and a control method thereof. Background Art

[0002] New energy vehicle parking spaces are suitable for parking lots, residential areas, charging stations and other scenarios, and can be used for parking and charging new energy vehicles. However, existing parking spaces generally only have temperature sensors installed on the top. The starting point of thermal runaway of the lithium battery of new energy vehicles is inside the battery pack. The roof temperature may lag in reflecting the actual fire situation and cannot provide timely warnings. At the same time, mechanical parking spaces or ground locks block the bottom of the vehicle, resulting in a lack of monitoring under the vehicle, making it impossible to directly capture abnormal surface temperature of the battery pack, resulting in a temperature monitoring blind spot in the current parking space. In addition, traditional fire sprinklers are usually installed on the top of the parking space. In the early stage of thermal runaway of the lithium battery, the fire sprinklers are blocked by vehicles and cannot extinguish the fire in time, and the deployment of fire extinguishing equipment is not reasonable. Summary of the Invention

[0036] See also Figure 1-Figure 5 , an embodiment of the present invention provides an automatic fire extinguishing system for a new energy vehicle charging and parking area, comprising:

[0037] A fire extinguishing agent tank 10, used for storing fire extinguishing agent;

[0038] The fire extinguishing module 20 includes a plurality of horizontal fire extinguishing integrated devices 21 and a plurality of full-coverage fire extinguishing devices 22 connected to the fire extinguishing agent tank 10. The plurality of horizontal fire extinguishing integrated devices 21 are respectively arranged at each parking space 50, and the plurality of full-coverage fire extinguishing devices 22 are respectively arranged above each parking space 50. Each horizontal fire extinguishing integrated device 21 is equipped with an under-vehicle fire detector 30.

[0039] The fire host control device 40 is electrically connected to the under-vehicle fire detector 30, the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of each parking space 50, and is used to receive the fire detection signals collected by the under-vehicle fire detector 30 of each parking space 50, and convert the fire detection signals into corresponding fire extinguishing control signals to control the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of the corresponding parking space 50 to automatically extinguish the fire in different areas.

[0040] In this embodiment, the fire extinguishing agent tank 10 may comprise a pressure-storage container, and the fire extinguishing agent comprises a lithium battery-specific fire extinguishing agent. Compressed nitrogen is provided in the pressure-storage container as a propulsion source, and a spray device controls the discharge of the lithium battery-specific fire extinguishing agent from the pressure-storage container. Using a lithium battery-specific fire extinguishing agent can more quickly and effectively control fires than using water, resulting in high fire extinguishing efficiency.

[0041] There are generally multiple parking spaces 50 for new energy vehicles. In this embodiment, each parking space 50 is equipped with a fire extinguishing module 20 .

[0042] Specifically, the fire extinguishing module 20 includes a plurality of horizontal fire extinguishing integrated devices 21 and a plurality of full-coverage fire extinguishing devices 22 connected to the fire extinguishing agent tank 10. The plurality of horizontal fire extinguishing integrated devices 21 are respectively arranged at each parking space 50. When a new energy vehicle is parked, the horizontal fire extinguishing integrated device 21 is located below the new energy vehicle. The plurality of full-coverage fire extinguishing devices 22 are respectively arranged above each parking space 50, such as at the position of the awning or the top of the garage. When a new energy vehicle catches fire, the horizontal fire extinguishing integrated device 30 close to the fire source can automatically extinguish the fire below the new energy vehicle in time to control the fire. The full-coverage fire extinguishing device 22 has a large spraying area and can automatically extinguish the fire from above the new energy vehicle to prevent the fire from spreading. The fire extinguishing device of this embodiment is reasonably deployed.

[0043] Each horizontal fire extinguishing integrated device 21 is equipped with an undercar fire detector 30, which can read environmental parameters in real time and independently detect the fire situation in each parking space 50. It can also be used to formulate more efficient and appropriate fire fighting measures according to different environmental parameters.

[0044] In a specific embodiment, the under-vehicle fire detector 30 includes a composite fire detection sensor that can detect ambient temperature, smoke concentration, combustible gas (such as H2, CH4, etc.) concentration, etc., and output temperature signals, smoke concentration signals, combustible gas concentration signals, etc. to achieve accurate fire monitoring.

[0045] The fire host control device 40 is electrically connected to the undercar fire detectors 30, the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of each parking space 50, forming a one-master-multiple-control fire monitoring mechanism.

[0046] Specifically, multiple parking spaces 50 are divided into different fire monitoring areas. When a new energy vehicle in a parking space 50 burns, it will cause changes in the surrounding temperature and some gas concentrations. The undercar fire detector 30 on the parking space 50 will immediately capture the changes in the surrounding environment and transmit the detection signal to the fire host control device 40. The detection signal includes a fire detection signal and a non-fire detection signal. The fire host control device 40 receives the fire detection signal collected by the undercar fire detector 30 of the parking space 50, and then converts the fire detection signal into a corresponding fire extinguishing control signal to control the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of the parking space 50 to automatically extinguish the fire in different areas. At the same time, the fire host control device 40 can also link the alarm device to sound an alarm, and link the original garage's fire extinguishing system to extinguish the fire, making fire prevention and control more effective.

[0047] See also Figure 1In a specific embodiment, the fire extinguishing agent tank 10 and the fire host control device 40 are arranged on one side of all parking spaces 50, and multiple horizontal fire extinguishing integrated devices 21 and multiple full-coverage fire extinguishing devices 22 are longitudinally arranged in the corresponding parking space 50 area.

[0048] In this embodiment, the fire extinguisher tank 10 and the fire control unit 40 are located on one side of each parking space 50, facilitating the delivery of fire extinguisher and the management of the fire extinguishing modules 20 without hindering vehicle access. Multiple horizontal fire extinguishing integrated devices 21 and multiple full-coverage fire extinguishing devices 22 are positioned longitudinally (in the direction of new energy vehicle access) within the corresponding parking spaces 50, facilitating precise fire extinguishing of vehicles in those spaces.

[0049] See also Figure 1-Figure 3 In a specific embodiment, each of the horizontal fire extinguishing integrated devices 21 includes a shell 211, a first nozzle 212, a first solenoid valve 213 and a first pipeline 214. The shell 211 is set at each parking space 50, and the under-vehicle fire detector 30, the first nozzle 212 and the first solenoid valve 213 are set on the shell 211. The first nozzle 212 is connected to the fire extinguishing agent tank 10 through the first pipeline 214, and the first solenoid valve 213 is electrically connected to the fire host control device 40.

[0050] In this embodiment, the housing 211 of the horizontal integrated fire extinguishing device 21 is installed in each parking space 50. Housing 211 houses an under-vehicle fire detector 30, a first nozzle 212, and a first solenoid valve 213. The under-vehicle fire detector 30 can detect fires in each parking space 50 in real time. Upon detecting a fire, it transmits a fire detection signal to the fire control unit 40. Upon receiving the fire detection signal for that parking space 50, the fire control unit 40 controls the opening of the first solenoid valve 213 in that parking space 50, allowing the fire extinguishing agent in the first pipeline 214 to be sprayed from the first nozzle 212, achieving automatic zoned fire extinguishing.

[0051] The horizontal fire extinguishing integrated device 21 of this embodiment is small in size and is suitable for newly installed parking spaces for new energy vehicles, and is also very convenient for replacing and renovating existing parking spaces for new energy vehicles. In addition, the housing 211 can be made of metal material, which is economical and efficient.

[0052] See also Figure 2-Figure 3 In a specific embodiment, there are multiple first nozzles 212, and the shell 211 includes a top surface 2111, a bottom surface and a ring side surface 2112. The top surface 2111 and the ring side surface 2112 are both provided with multiple fire extinguishing holes, and multiple first nozzles 212 extend from the corresponding fire extinguishing holes respectively.

[0053] In this embodiment, multi-angle fire extinguishing through holes are opened on the shell 211, and multiple first nozzles 212 extend from the corresponding fire extinguishing through holes respectively, so as to realize full-angle spraying of fire extinguishing agent and improve fire extinguishing efficiency.

[0054] See also Figure 2-Figure 3 In a specific embodiment, the first pipeline 214 includes a first transport pipeline 2141 and multiple first branch pipelines 2142, the first transport pipeline 2141 is respectively connected to the fire extinguishing agent tank 10 and communicates with multiple first branch pipelines 2142, the first solenoid valve 213 is arranged at the connection between the first transport pipeline 2141 and the multiple first branch pipelines 2142, and the multiple first branch pipelines 2142 are arranged inside the shell 211 and connected to the corresponding first nozzles 212.

[0055] In this embodiment, when the first solenoid valve 213 of a certain parking space 50 is controlled to open, the fire extinguishing agent in the fire extinguishing agent tank 10 is transported to the multiple first branch pipelines 2142 through the first transport pipeline 2141, and then sprayed from the multiple first nozzles 212, and the fire extinguishing control is precise.

[0056] See also Figure 1-Figure 3 In a specific embodiment, the ring side surfaces 2112 are all sloped surfaces, and the top surface 2111 and the ring side surfaces 2112 are both provided with a plurality of air holes 215 .

[0057] In this embodiment, the side surfaces 2112 of each housing 211 are sloped. This slope enhances collision resistance and significantly reduces rebound forces, whether for pedestrians stepping on or vehicles running over the horizontal fire extinguishing integrated device 21. Furthermore, the housing 211 is thick and features ventilation holes 215, which protect the internal components while ensuring air circulation inside and outside, ensuring the proper functioning of the undercar fire detector 30.

[0058] See also Figure 1 and Figure 5 In a specific embodiment, each of the full-coverage fire extinguishing devices 22 includes a second nozzle 221, a second solenoid valve 222, and a second pipeline 223. The second pipeline 223 is arranged above each parking space 50. The second nozzle 221 and the second solenoid valve 222 are arranged on the second pipeline 223. The second nozzle 221 is connected to the fire extinguishing agent tank 10 through the second pipeline 223, and the second solenoid valve 222 is electrically connected to the fire host control device 40.

[0059] In this embodiment, when the second solenoid valve 222 of a certain parking space 50 is controlled to open, the fire extinguishing agent in the fire extinguishing agent tank 10 is transported through the second pipeline 223 and then sprayed out from the second nozzle 221. In conjunction with the horizontal fire extinguishing integrated device 21, the fire extinguishing control is precise.

[0060] See also Figure 5 In a specific embodiment, each second pipeline 223 is provided with a plurality of second nozzles 221 along the longitudinal direction of the parking space 50 .

[0061] In this embodiment, a plurality of second nozzles 221 are arranged on the second pipeline 223 at intervals along the longitudinal direction of the parking space 50, so as to realize the spraying of fire extinguishing agent at multiple positions and improve the fire extinguishing efficiency.

[0062] To sum up, compared with the existing technology, the embodiment of the present invention provides an automatic fire extinguishing system for charging and parking areas of new energy vehicles, in which an under-vehicle fire detector 30, a horizontal fire extinguishing integrated device 21 and a full-coverage fire extinguishing device 22 are arranged in each parking space 50. The fire host control device 40 receives the fire detection signal collected by the under-vehicle fire detector 30 of each parking space 50, and converts the fire detection signal into a corresponding fire extinguishing control signal to control the horizontal fire extinguishing integrated device 21 and the full-coverage fire extinguishing device 22 of the corresponding parking space 50 to automatically extinguish the fire in a zoned manner. By configuring an under-vehicle fire detector 30 and a dual fire extinguishing device in each parking space 50 and a one-master and multi-control fire monitoring mechanism, accurate fire monitoring and zoned fire extinguishing of new energy vehicle parking spaces are achieved, thereby improving fire extinguishing efficiency and effectiveness.
