[0002] With the popularity of electric vehicles, battery swap cabinets have been widely used as a convenient way to replenish energy. However, the frequent fire accidents in the use of battery swap cabinets have not only caused serious property losses, but also threatened public safety. The causes of fire in the battery swap cabinet in the prior art are diverse and complex, mainly including battery line short circuit, battery pack imbalance, battery material problems, and electrical failures.

[0040] See also Figure 1 to Figure 5 In the disclosed embodiment, a power exchange cabinet with a fire extinguishing function includes a cabinet 1, in which a plurality of compartments 2 for storing battery modules are arranged, a fire extinguishing water tank 3 arranged below the compartment 2, a sensing device 4, a central platform 5, and a control system 6; the compartment 2 includes a battery ejection compartment 21, a battery tray 22, a sliding device 23, and a compartment fire extinguishing system 24, wherein the sliding device 23 is arranged between the battery ejection compartment 21 and the battery tray 22, and the compartment fire extinguishing system 24 is arranged above the battery ejection compartment 21; the fire extinguishing water tank 3 is arranged below the compartment 2, and the fire extinguishing water tank 3 is an open structure. The sensing device 4 is distributed on the mounting surface above the interior of the compartment 2 and is electrically connected to the control system 6; the central platform 5 is electrically connected to the control system 6.

[0041] In this embodiment, the electrical connection between the control system and the central platform enables the battery exchange cabinet to be remotely monitored and managed, facilitating the timely discovery and handling of potential safety hazards.

[0042] like Figures 2-3As shown, the battery ejection compartment 21 includes an ejection tray 211, an ejection support frame 212, a temperature sensing pin 213, and a compression spring 214. The lower surfaces of the left and right sides of the ejection tray 211 are fixedly connected to the sliding surface of the sliding device 23. The ejection support frame 212 includes a connecting rod 2121, a front connecting plate 2122, a rear connecting plate 2123, a transverse connecting plate 2124, and a back plate 2125. The connecting rod 2121 is connected between the front connecting plate 2122 and the rear connecting plate 2123. The front connecting plate 2122 and the rear connecting plate 2123 are symmetrically arranged. The transverse connecting plate 2124 fixedly connects the rear connecting plates 2123 on both sides. The compression spring 214 runs through the connecting rod 2121. In this embodiment, the design of the ejection tray, the ejection support frame, the temperature sensing pin and other components not only realizes the rapid ejection of the battery, but also ensures the stability and reliability of the structure.

[0043] The battery tray 22 is fixed to the upper surface in the warehouse body 2, and the bottom surface of the battery tray 22 is fixed to the fixed surface of the sliding device 23. The battery tray 22 includes a tray bottom plate 221 and a tray connecting frame 222, wherein the fixed surface of the sliding device 23 is fixed to the upper surfaces of the left and right sides of the tray bottom plate 221, and the tray connecting frame 222 is vertically fixedly installed on the upper surface of the tray bottom plate 221. The tray connecting frame 222 includes left and right vertical upright plates 2221, a tray cross beam 2222, and an ejection warehouse connecting block 2223. The ejection warehouse connecting block 2223 is fixedly connected to the left and right sides of the tray cross beam 2222. A connecting hole is provided in the ejection warehouse connecting block 2223, and the connecting hole is concentrically connected to the connecting rod 2121.

[0044] Furthermore, the ejection support frame 212 further includes a temperature sensing connecting plate 2126, which is fixed at the center of the transverse connecting plate 2124 and has a center hole at the front end. The front end of the tray crossbeam 2222 further includes a crossbeam temperature connecting plate 2224, which has a connecting hole of the same size as the center hole of the temperature sensing connecting plate 2126, and the temperature sensing pin 213 is inserted through the connecting hole and the center hole.

[0045] Preferably, the compression spring 214 is in a compressed state between the tray connection frame 222 and the ejection support frame 212, the ejection spring 214 is made of high temperature resistant material, and the temperature sensing pin 213 is made of combustible plastic. The compression spring and the fire extinguishing connector and other components are made of high temperature resistant material, which can maintain normal operation in a high temperature environment, thereby improving the overall fire resistance of the power exchange cabinet.

[0046] In this example, the temperature sensing pin 213 fixes the ejection tray 211 and the ejection support frame 212 together when the battery is not on fire, and the ejection spring 214 is in a compressed state. When a fire occurs, the temperature sensing pin 213 becomes soft due to the high temperature, and the ejection tray 211 is separated from the ejection support frame 212 under the action of the ejection spring 214, and the battery is ejected into the fire extinguishing water tank 3. By providing an ejection mechanism of the temperature sensing pin and the compression spring, this embodiment can quickly eject the battery into the fire extinguishing water tank when the battery catches fire, effectively isolate the fire source and extinguish the flame, and greatly reduce the possibility of fire and the risk of spreading.

[0047] It should be noted that the temperature sensing pin is not limited to combustible plastics, and any material with a melting point exceeding 300° can be used, which will not be elaborated again.

[0048] like Figure 4 As shown, the warehouse fire extinguishing system 24 includes a monitoring device 241, a fire extinguishing device 242 and a connecting device 243, wherein the monitoring device 241 includes an airbag 2411 and a piston rod 2412, the fire extinguishing device 242 includes a nozzle 2421 and a fire extinguishing fuel bottle 2422, the connecting device 243 includes a fire extinguishing connecting piece 2431 and a connecting hose 2432, the monitoring device 241 is arranged on the upper surface of the ejection support frame 212, and the connecting device connects the monitoring device 241 and the fire extinguishing device 242 together; the airbag 2411, the piston rod 2412, and the fire extinguishing connecting piece 2431 are on the same axis, the piston rod 2412 passes through the airbag 2411 and passes through the center position of the connecting piece 2431, the nozzle 2421 is connected to the fire extinguishing connecting piece 2431, and the connecting hose 2432 is connected to the fire extinguishing fuel bottle 2422 and the fire extinguishing connecting piece 2431 in sequence. Through the installation of fire-extinguishing water tanks and fire-extinguishing fuel bottles, the power exchange cabinet can adapt to fire situations of different scales and types, improving the flexibility and applicability of its fire-fighting capabilities.

[0049] The airbag 2411 includes an airbag body 24111 and an airbag connecting tube 24112. The airbag connecting tube 24112 is connected to the rear end of the airbag body 24111. The airbag body 24111 is filled with compressed air. The piston rod 2412 includes a piston connecting rod 24121 and a piston connecting block 24122. The piston connecting rod 24121 is placed inside the airbag connecting tube 24112. The piston connecting block 24122 is placed inside the center of the fire extinguishing connecting piece 2431, and a through hole is set at the center position in the left and right directions. The fire extinguishing connecting piece 2431 has a connecting hole at the center position in the up and down directions that can be centrally aligned with the through hole.

[0050] Furthermore, the fire extinguishing connecting piece 2431 includes a cavity 24311 and a hose connecting block 24312. The cavity 24311 is a vertically symmetrical structure and is provided with a connecting hole. The connecting hole is a stepped hole, and the stepped holes are symmetrically arranged up and down. The hose connecting block 24312 is stepped and has a connecting hole inside. The hose connecting block 24312 is placed in the upper stepped hole of the fire extinguishing connecting piece 2431, and the lower stepped hole is connected to the nozzle 2421.

[0051] The cavity 24311 is sealed and connected to the hose connecting block 24312. One end of the connecting hose 2432 is nested and connected to the hose connecting block 24312, and the other end is connected to the fire extinguishing fuel bottle 2422. The fire extinguishing fuel bottle 2422 is arranged on the rear side of the fire extinguishing water tank 3, and the fire extinguishing fuel bottle 2422 can be connected to multiple sets of hoses.

[0052] In this example, when the battery in the bin body catches fire, the bin body temperature rises, and the airbag body 24111 expands due to the heat, pushing the piston connecting block 24122 so that the through hole of the piston connecting block 24122 coincides with the connecting hole of the hose connecting block 24312, and then the nozzle 2421 can spray out the fire extinguishing agent. This embodiment further enhances the fire extinguishing effect through the design of the bin body fire extinguishing system, including the airbag expansion pushing the piston connecting block to spray out the fire extinguishing agent, and ensures the safety of the battery exchange cabinet and the surrounding environment.

[0053] like Figure 1 As shown, the fire extinguishing water tank 3 is arranged below the warehouse body 2, and the fire extinguishing water tank 3 is filled with a fire extinguishing agent, which is composed of water and a flame retardant. This combination of fire extinguishing agents can more effectively extinguish battery fires and prevent re-ignition.

[0054] A liquid level gauge is provided in the fire extinguishing water tank 3, and the liquid level gauge is set to the highest position and the lowest position. A solenoid valve is provided on the right side of the fire extinguishing water tank, and the solenoid valve is electrically connected to the liquid level gauge. The provision of the liquid level gauge and the solenoid valve in this embodiment ensures that the fire extinguishing agent in the fire extinguishing water tank is sufficient, while reducing the frequency and cost of manual maintenance.

[0055] In this embodiment, the fire extinguishing water tank is connected to an external water source, and when the liquid level of the fire extinguishing water tank 3 reaches the lowest level, the water is connected by a solenoid valve.

[0056] In this embodiment, the sensing device includes a temperature sensing device and a smoke sensing device. The temperature sensing device and the smoke sensing device are arranged below the warehouse. When the temperature sensor senses that the temperature change in the warehouse exceeds a preset threshold, an alarm is triggered and the central platform is notified. When the smoke sensing device senses that the smoke concentration in the warehouse exceeds a preset threshold, an alarm is triggered and the central platform is notified. The sensing device (including the temperature sensing device and the smoke sensing device) of this embodiment can monitor the temperature and smoke concentration in the warehouse in real time. Once the preset threshold is exceeded, an alarm is triggered and the central platform is notified, thereby realizing timely discovery and rapid response to fire.

[0057] The fire extinguishing tank contains a fire extinguishing agent consisting of water and flame retardant. This combination can more effectively extinguish battery fires and prevent re-ignition.

[0058] Preferably, the control system consists of multiple warehouse control systems and fire extinguishing water tank control systems, wherein the warehouse control system controls the power supply inside the warehouse. When the temperature sensing device and the smoke sensing device inside the warehouse exceed the preset threshold value, the central platform receives the signal and sends a power-off command to the warehouse control system. When the liquid level meter reaches the lowest position, the central platform receives the signal and sends a water connection command to the fire extinguishing water tank control system.

[0059] The working principle of the present invention is as follows: when the battery is charging in the warehouse, the ejection tray and the ejection support frame are fixed together by the temperature sensing pin and the compression spring. If the battery suddenly catches fire, the temperature in the warehouse will rise rapidly, the temperature sensing pin will soften due to the heat, and the ejection support frame will be ejected into the fire extinguishing water tank under the warehouse under the force of the compression spring to extinguish the battery; at the same time, the airbag body expands due to the heat and pushes the piston connecting block so that the through hole of the piston connecting block coincides with the connecting hole of the hose connecting block, and then the nozzle sprays the fire extinguishing agent to extinguish the fire in the warehouse.

[0060] The above specific implementations do not constitute a limitation on the protection scope of the present disclosure. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
