[0067]

[0068] The embodiments of the present disclosure are described in detail below with reference to the embodiments and drawings, but the embodiments of the present disclosure are not limited thereto. Specific embodiment 1:

[0070] The present disclosure provides an embodiment:

[0071] As Figure 1 , a rapid fire extinguishing system for new energy vehicles, comprising: a linkage controller 1, a telescopic fireproof heat shield 2, a liquid spraying unit 3, a collection component 4, a liquid discharge component 5, an audible and visual alarm component 6, and a communication component 7; wherein the telescopic fireproof heat shield 2, such as an electric telescopic rod, is electrically connected with the linkage controller 1, and is used to stretch or retract by using the instructions sent by the linkage controller 1 to form a liquid blocking cofferdam or lift the cofferdam around the vehicle to be extinguished; the liquid spraying unit 3, such as a spray head, is arranged on the telescopic fireproof heat shield 2, and is used to spray liquid to the vehicle to be extinguished in the liquid blocking cofferdam for fire extinguishing; the collection component 4 is arranged on the telescopic fireproof heat shield 2, and is used to collect environmental data, such as temperature, smoke, flammable or harmful gas, etc., around the vehicle to be extinguished; the linkage controller 1 is electrically connected with the collection component 4, and is used to collect the environmental data; and the environmental data is judged, and a control instruction is issued; the liquid spraying unit 3 is electrically connected with the linkage controller 1, and is used to work according to the instructions sent by the linkage controller 1. The output end of the liquid spraying unit 3 faces the vehicle to be extinguished, and the input end is connected with the external liquid supply unit, such as a fire sprinkler system or a container filled with fire extinguishing liquid; the linkage controller 1 can be any programmable control element, such as a single-chip microcomputer, etc.

[0072] In order to more specifically illustrate the specific technical solutions of the embodiment, the placement place of the new energy vehicle can be specifically the new energy vehicle parking lot.

[0073] Specifically, as Figure 2 , the telescopic fireproof heat shield 2 comprises a support 201, four telescopic assemblies 202, a flexible member 203, and a sealing assembly 204. The support 201 is arranged above the place where the vehicle is placed, such as above the garage. One end of each of the four telescopic assemblies 202 is arranged on the support 201 and located directly above each vehicle. The four telescopic assemblies 202 form a square. The flexible member 203 is arranged outside the telescopic assembly 202 and is used to form a liquid blocking cofferdam. The flexible member 203 can be a waterproof and high-temperature-resistant fireproof cloth, such as a glass fiber cloth, a ceramic fiber cloth, or other lightweight non-combustible materials with high fire resistance. It can be reused and is easy to replace if damaged. Preferably, the length and width of the flexible member 203 are set according to the size of the parking space, and the height is preferably 0.5-1.5 meters. The telescopic assembly 202, the support 201, and the like are preferably made of metal materials such as galvanized steel plates and stainless steel plates, which have strong support stability. The sealing assembly 204 is arranged at the bottom of the flexible member 203 and is used to improve the sealing performance of the liquid blocking cofferdam. The liquid spraying unit 3 and the collecting assembly 4 can be arranged on the support 201. The support 201 can be arranged on the top of the garage. The telescopic assembly 202 is electrically connected to the linkage controller 1 and is telescoped according to the instructions of the linkage controller 1. In the event of a fire, it is telescoped from the support 201 to the ground and forms a liquid blocking cofferdam around the vehicle to be extinguished.

[0074] As Figure 3 , in order to prevent the cooling liquid in the liquid blocking cofferdam from leaking, the sealing assembly 204 comprises a liquid pumping unit 2041 and a flexible sealing cylinder member 2042. The liquid pumping unit 2041, such as a water pump, is arranged on one side of the telescopic assembly 202 close to the ground. The input end of the liquid pumping unit 2041 is arranged towards the inside of the liquid blocking cofferdam and is used to pump the cooling liquid. The flexible sealing cylinder member 2042 is arranged at one end of the flexible member 203 close to the ground. The head and tail of the flexible sealing cylinder member 2042 are connected and connected to the output end of the liquid pumping unit 2041 through a pipeline. The liquid pumping unit 2041 is electrically connected to the linkage controller 1 and is used to inject liquid into the flexible sealing cylinder member 2042 after receiving the liquid pumping instruction from the linkage controller 1 to form a seal at the bottom of the liquid blocking cofferdam. Preferably, the material of the flexible sealing cylinder member 2042 is the same as that of the flexible member 203. Figure 3When in use, the water in the liquid-blocking cofferdam is pumped into the flexible sealing cylinder 2042 through the liquid pumping unit 2041, so that it is filled with liquid. Due to the action of gravity, the flexible sealing cylinder 2042 will deform with the ground. In the initial stage, a small amount of liquid droplets are allowed to overflow briefly. After the flexible cylinder is fully in contact with the ground, it can effectively prevent the cooling liquid from flowing out. At the same time, the telescopic assembly 202 can also be pulled downward to maintain the stability of the telescopic assembly 202 and prevent the liquid level from increasing, causing the telescopic assembly 202 to deflect. Similarly, after the fire is extinguished, the linkage controller 1 sends a liquid pumping instruction to the liquid pumping unit 2041 to pump out the liquid in the flexible sealing cylinder 2042 and restore the flexible sealing cylinder 2042 to its original state. Figure 3 The arrow direction in the figure is the flow direction diagram of the water supply from the pumping unit 2041 to the flexible sealing cylinder 2042.

[0075] In order to improve the cooling effect, the retractable fire-fighting heat insulation cover 2 may further include: a liquid temperature detection unit; the liquid temperature detection unit is arranged on the flexible part 203, and is used to detect the liquid temperature data in the liquid retaining cofferdam; the linkage controller 1 is electrically connected to the liquid temperature detection unit, and is used to control the flow rate or liquid supply mode of the spray unit 3 according to the liquid temperature data, to ensure that the fire can be quickly controlled, and the tram can be continuously cooled in the later stage to prevent re-ignition.

[0076] In order to increase identifiability, the rapid fire extinguishing system described in this embodiment also includes: an audible and visual alarm component 6 and a communication component 7; the audible and visual alarm component 6 is electrically connected to the linkage controller 1, and is used to perform audible and visual alarms according to the alarm signal issued by the linkage controller 1; the communication component 7 is electrically connected to the linkage controller 1, and is used to send alarm information to the fire control center according to the alarm signal issued by the linkage controller 1.

[0077] In order to prevent the flow of fire-fighting wastewater and pollute the environment, such as Figure 4 and Figure 5 The rapid fire extinguishing system for energy storage station fires also includes: a drainage component 5; the drainage component 5 includes: at least one drainage unit 501, a drainage pipeline 502, and a liquid reservoir 503; wherein the drainage unit 501, such as a controllable floor drain, is located on the inner side of the retractable fire-fighting heat insulation cover 2; one end of the drainage pipeline 502 is connected to the drainage unit 501 and is arranged underground where the vehicle to be extinguished is placed; a controllable valve is provided in the drainage pipeline to control the on-off; the liquid reservoir 503 is connected to the other end of the drainage pipeline 502 for collecting waste liquid generated by fire extinguishing.

[0078] The quick fire extinguishing system described in the specific embodiment 1 is not limited to extinguishing fire of the new energy vehicle, and any energy storage station with a battery cluster can use the technical solution in the specific embodiment 1. For example, when a dangerous signal of the battery cluster is detected in the energy storage station, the battery cluster is popped out, placed on the guide rail by the mechanical hand or the tray, transported to the bottom of the liquid retaining weir, and subjected to the fire extinguishing scheme as in the specific embodiment 1. Specific embodiment 2:

[0080] The present disclosure provides an embodiment:

[0081] On the basis of the specific embodiment 1, the present disclosure further provides an embodiment.

[0082] In order to improve the effect, the liquid drainage assembly 5 can also be preferably:

[0083] The liquid drainage assembly 5, such as Figure 6 and 7 , comprises at least one liquid drainage groove 504 and a liquid storage pool 503; wherein the liquid drainage groove 504 is arranged on the ground for placing the vehicle to be extinguished, and is located below the telescopic fireproof cover 2, for receiving waste liquid when the telescopic fireproof cover 2 is lifted by the linkage controller 1; the liquid storage pool 503 is arranged in communication with any of the liquid drainage grooves 504, for collecting waste liquid generated by fire extinguishing; the width of the liquid drainage groove 504 is greater than the width of the sealing assembly 204 in the telescopic fireproof cover 2.

[0084] The liquid drainage assembly 5 disclosed in the embodiment collects waste water through the liquid drainage groove 504, while the specific embodiment 1 does not have the liquid drainage groove 504, and waste water is collected through the liquid drainage pipeline 502; at the same time, the liquid drainage groove 504 provided in the embodiment can also prevent waste water from flowing.

[0085] In addition to improving the waste water collection structure, the technical solution provided in the embodiment also has a structure for preventing waste water from overflowing; specifically:

[0086] For example Figure 8 and Figure 9 , the diameter of the flexible sealing cylinder 2042 is less than the width of the liquid drainage groove 504, so that the flexible sealing cylinder 2042 is extruded by gravity and the ground after being put into the liquid drainage groove 504, deforms, and a small amount of liquid droplets overflowing in the initial stage are all collected in the liquid drainage groove 504; and the liquid drainage unit 501 is arranged at the bottom of the liquid drainage groove 504, so that the waste water after fire extinguishing flows from the bottom of the weir to the liquid drainage groove 504, and is collected in the drainage pipeline network.

[0087] Especially need to explain is, after the fire is extinguished, the need to carry out waste liquid collection work. Because the flexible sealing cylinder member 2042 is arranged in the drainage groove 504 in the embodiment, the waste liquid is easy to be stirred and overflow from the drainage groove 504 in the process of lifting the flexible sealing cylinder member 2042, resulting in failure of waste liquid collection.

[0088] In view of this, the structure of the flexible sealing cylinder member 2042 is further optimized in the embodiment.

[0089] Specifically, the bottom of the flexible sealing cylinder member 2042, that is, the side towards the bottom of the drainage groove 504, is provided with an extension 2042A and a plurality of fixing portions 2042B; wherein the material of the extension 2042A is consistent with the flexible member 203, and when the flexible sealing cylinder member 2042 is pulled out of the drainage groove 504, the end of the extension 2042A is fixedly connected with the bottom of the drainage groove 504 through the fixing portion 2042B, so that the stirred waste liquid cannot overflow from the secondary cofferdam formed by the extension 2042A, and the waste liquid collection effect is ensured. Figure 8 and Figure 9 S in the above formula is the position of the permanent magnet.

[0090] And for the fixing portion 2042B connected with the bottom of the drainage groove 504, the connection can be achieved by means of an electromagnet. The fixing portion 2042B is arranged at the end of the extension 2042A towards the drainage groove 504, and is electrically connected with the linkage controller 1; when the telescopic fireproof heat shield 2 receives the falling signal, the fixing portion 2042B is electrified to generate a heterogeneous magnetic field with another permanent magnet embedded in the drainage groove 504. When the fixing portion 2042B falls into the drainage groove 504, the fixing portion 2042B is attracted to the permanent magnet, so that the extension 2042A is stacked in the drainage groove 504; preferably, the permanent magnet is located outside the drainage unit 501 to prevent the extension 2042A from blocking the drainage unit 501. After the collection of waste liquid is completed, the fixing portion 2042B is de-energized and separated from the permanent magnet by sending a command by the linkage controller 1, and the telescopic fireproof heat shield 2 is reset.

[0091] Figure 9 The position relationship of the extension 2042A, the fixing portion 2042B and the drainage unit 501 when the flexible sealing cylinder member 2042 completely falls down is shown. Specific embodiment 3:

[0093] The present disclosure also provides an embodiment:

[0094] As Figure 10A quick fire extinguishing method for new energy vehicles, based on the quick fire extinguishing system of embodiment 1, the specific fire extinguishing steps include: detecting the temperature information, smoke information and gas information of any vehicle top, and sending the above data to the linkage controller; in this example, the sensor is arranged on the top of the vehicle, and the position of the vehicle to be extinguished can be obtained according to the temperature information, smoke information and gas information; the telescopic fireproof heat shield 2 is telescoped from top to bottom to form a liquid retaining cofferdam around the vehicle to be extinguished; liquid is sprayed into the liquid retaining cofferdam to extinguish the vehicle to be extinguished.

[0095] It should be noted that: in this embodiment, "obtaining the position of the vehicle to be extinguished through temperature information, smoke information and gas information" is prior art, which will not be described herein.

[0096] Specifically, spraying liquid into the liquid retaining cofferdam to extinguish the vehicle to be extinguished includes: when the telescopic fireproof heat shield 2 is lowered to the ground, the vehicle to be extinguished is flooded by continuous liquid flow for extinguishing; the continuous liquid flow can be used as a first liquid supply mode; through the above continuous liquid supply mode, the vehicle to be extinguished can be quickly flooded; and after the vehicle to be extinguished is flooded, a continuous low temperature and oxygen isolation environment is formed for the battery pack inside the vehicle to be extinguished, effectively inhibiting the thermal runaway reaction of the battery pack and its propagation process, and then quickly extinguishing the vehicle to be extinguished. The liquid temperature in the liquid retaining cofferdam is continuously collected, if the open fire is extinguished and the liquid temperature does not exceed the preset temperature threshold within the preset time, the liquid spraying mode is switched from continuous fast to intermittent slow. Due to the characteristics of battery fire, although the vehicle to be extinguished is flooded, if the vehicle to be extinguished is exposed to air again within a short time, there is still a possibility of rekindling; at this time, the vehicle to be extinguished is immersed in the cofferdam for a certain period of time, such as 1-2h, and the liquid temperature does not rise again, which can ensure that the vehicle to be extinguished cannot rekindle; the liquid spraying assembly is closed, and the underground liquid drainage system is started to collect wastewater.

[0097] Alternatively, the liquid temperature in the liquid retaining cofferdam is continuously collected, and if the liquid temperature exceeds a preset temperature threshold within a preset time or the open fire is not extinguished, the underground liquid drainage system is started; at the same time, the first liquid supply mode is continued to flood the vehicle to be extinguished, and when the open fire is extinguished and the liquid temperature data is lower than the preset temperature threshold within a preset time, the underground liquid drainage system is closed, the liquid spraying mode is switched from continuous fast to intermittent slow, and cooling is maintained. If the liquid temperature does not rise within a certain time, such as 1-2h, it can be ensured that the vehicle to be extinguished cannot be re-ignited; the liquid spraying assembly is closed, and the underground liquid drainage system is started. The preset temperature threshold is 50-80℃; the preset time is 30-60min; the intermittent slow flow rate is controlled at 40%-60% of the continuous liquid flow, and the interval of each liquid supply is controlled at 10-20min. The liquid extinguishing agent sprayed by the liquid spraying assembly can be one of water, high-pressure fine water mist, perfluorohexone and other extinguishing agents that are liquid at room temperature. The liquid supply speed of the first liquid supply mode can be adjusted according to the actual situation. For example, after the liquid retaining cofferdam is formed, the flow rate is preferably adjusted to reach the height of the door handle of the vehicle to be extinguished within 3 minutes.

[0098] The starting of the underground liquid drainage system includes: draining liquid through the liquid drainage unit 501; or lifting the telescopic fireproof heat shield 2 to make the liquid flow from the bottom of the telescopic fireproof heat shield 2 into the liquid drainage groove 504 for collection, preventing the waste liquid from flowing.

[0099] It should be noted that the new energy vehicle charging station and parking lot disclosed in the embodiment can be used in any fixed battery group application to extinguish fire using the rapid fire extinguishing method.

[0100] The above only describes the preferred embodiments of the disclosure and is not intended to limit the disclosure. Any modifications, equivalent replacements and improvements made within the spirit and principles of the disclosure shall be included in the protection scope of the disclosure.
