[0034] Please see Figures 1 to 5This utility model provides an embodiment of a fire-safe battery charging and energy storage cabinet, including a cabinet body 100. A battery rack 200 is arranged inside the cabinet body 100. The battery rack 200 includes a support frame 201 and a battery placement rack 202. Multiple battery placement racks 202 are arranged horizontally between two support frames 201. The upper surface of the battery placement rack 202 is covered with a mica board. Multiple battery packs are placed on the battery placement rack 202. Multiple fire extinguishing mechanisms 300 are included. One fire extinguishing mechanism 300 is located at the top of the inner cavity of the cabinet body 100. The other fire extinguishing mechanisms 300 are respectively located at the bottom of the multiple battery placement racks 202, so that the multiple fire extinguishing mechanisms 300 are respectively located above the multiple battery placement racks 202. Each fire extinguishing mechanism 300 corresponds to a single battery pack.

[0035] The fire extinguishing mechanism 300 includes a linear module 301 and a bend 304. The linear module 301 is fixed to the top of the inner cavity of the cabinet 100 and the bottom of multiple battery storage racks 202. The linear module 301 includes a lead screw frame, in which a lead screw is rotatably mounted. The lead screw is connected to a stepper motor at one end of the lead screw frame. The stepper motor is selected and used by technical personnel in this field according to the actual situation. A nut is threaded onto the lead screw, which serves as the moving end of the linear module 301. The stepper motor drives the lead screw to rotate, causing the nut to move along the lead screw. A connecting plate A302 is provided at the moving end of the linear module 301. The connecting plate A302 moves with the nut that serves as the moving end of the linear module 301; a connecting plate B303 is installed at the bottom of the connecting plate A302, a fixing plate 306 is installed at the bottom of the battery rack 202, a connecting pipe 308 is installed on the fixing plate 306, a delivery pump and a fire extinguishing agent compartment are installed inside the cabinet 100, the inlet end of the connecting pipe 308 is connected to the outlet end of the delivery pump through a pipe, and the inlet end of the delivery pump is connected to the outlet end of the fire extinguishing agent compartment through a pipe; a valve 309 is installed at the inlet end of the connecting pipe 308, the valve 309 is a solenoid valve, and the solenoid valve is selected and used by the technical personnel of this profession according to the actual situation.

[0036] The bend 304 passes through and is fixed on the connecting plate B303. The nozzle 305 is installed at the outlet end of the bend 304. The outlet end of the connecting pipe 308 is connected to the inlet end of the bend 304 by a telescopic pipe 307, which is a corrugated pipe.

[0037] When a fire occurs in the battery pack, sensors installed on the corresponding floor of the cabinet 100 detect smoke, combustible gases, etc., and the fire prevention and extinguishing control system inside the cabinet 100 executes the fire extinguishing command. The fire prevention and extinguishing control system includes a dedicated fire controller that communicates in real time with the BMS and EMS. The valve 309 on the floor where the burning battery pack is located is opened, and the delivery pump delivers the extinguishing agent in the extinguishing agent chamber to the connecting pipe 308 through which the valve 309 is opened. The extinguishing agent is sprayed out from the nozzle 305 after passing through the telescopic pipe 307 to extinguish the fire in the battery pack. At the same time, the linear module 301 drives the connecting plate A302 to move laterally back and forth, and the connecting plate B303 moves accordingly, causing the nozzle 305 to move back and forth. The telescopic pipe 307 extends and retracts accordingly, and the reciprocating nozzle 305 extinguishes the fire in the battery pack over a wide area.

[0038] This utility model, by setting up a linear module 301, connecting plate A302, connecting plate B303, bend 304, nozzle 305, fixing plate 306, telescopic pipe 307 and connecting pipe 308, has the advantages of the nozzle 305 reciprocating and spraying fire extinguishing agent over a wide area to extinguish the fire on the battery pack, and solves the problem of the cumbersome setting of multiple nozzles 305 and corresponding connecting pipes.

[0039] Please see Figures 3 to 5 This utility model provides an embodiment of a fire safety battery charging and energy storage cabinet. Four guide rods 310 are provided on a fixed plate 306. The guide rods 310 pass through a connecting plate B303. The four guide rods 310 are distributed around a telescopic tube 307 and parallel to the telescopic tube 307, forming a limiting mechanism for the telescopic tube 307. The telescopic tube 307 is supported on two of the guide rods 310. The limiting mechanism formed by the four guide rods 310 is used for the telescopic tube 307. Due to gravity, the telescopic tube 307 will sag. The two guide rods 310 below the telescopic tube 307 support the telescopic tube 307, ensuring that the telescopic tube 307 is in a normally telescopic state. The two guide rods 310 above the telescopic tube 307 limit the contraction and arching of the telescopic tube 307, ensuring that the telescopic tube 307 is in a normally telescopic state.

[0040] The guide rod 310 covers the travel range of the linear module 301, and the connecting plate B303 moves along the guide rod 310 throughout its entire travel.

[0041] This utility model has the advantage of setting guide rods 310, and having a limiting mechanism formed by four guide rods 310 for supporting the telescopic tube 307, so that the telescopic tube 307 is in a normal telescopic state and the normal telescopic extension and retraction of the telescopic tube 307 is not affected.

[0042] Please see Figure 6This utility model provides an embodiment of a fire safety battery charging and energy storage cabinet. The fire extinguishing mechanism 300 further includes a bracket 311. The top of the bracket 311 is fixed to the bottom of the nozzle 305. A truncated cone 312 is provided at the bottom of the bracket 311, with the tip of the truncated cone 312 facing the nozzle 305. When the extinguishing agent sprayed from the nozzle 305 comes into contact with the truncated cone 312, the tip of the truncated cone 312 disperses the sprayed extinguishing agent, thereby expanding the spray range of the extinguishing agent.

[0043] The bottom of the truncated cone 312 is provided with a flow divider 313, which includes a connecting ring 3131 and multiple flow dividers 3132. The connecting ring 3131 is located on the outer periphery of the bottom of the truncated cone 312, and the multiple flow dividers 3132 are evenly distributed and fixed on the circumferential surface of the connecting ring 3131. A space 3133 for the extinguishing agent to pass through is provided between any two adjacent flow dividers 3132. The flow dividers 3132 are inclined, with the end away from the truncated cone 312 being the lower end and the end facing the truncated cone 312 being the higher end. The extinguishing agent passing through the truncated cone 312 passes through the inclined flow dividers 3132 again, which further diffuses the extinguishing agent, further expanding the spray range of the extinguishing agent. In addition, some of the extinguishing agent passes through the space 3133, reducing the blind spot of the extinguishing agent spray.

[0044] This utility model, by setting up a bracket 311, a truncated cone 312, a connecting ring 3131, a diverter 3132, and a space 3133, has the advantages of further expanding the spray range of the extinguishing agent and enhancing the extinguishing effect; and that some of the extinguishing agent passes through the space 3133, reducing the extinguishing blind spot.

[0045] Working principle: When a fire occurs in the battery pack inside cabinet 100, the sensor installed on the corresponding layer of the battery pack inside cabinet 100 detects smoke, combustible gases, etc. The fire prevention and extinguishing control system inside cabinet 100 executes the extinguishing command, and the valve 309 on the layer where the burning battery pack is located is opened. The delivery pump delivers the extinguishing agent in the extinguishing agent chamber to the connecting pipe 308 of the opened valve 309. After passing through the telescopic pipe 307, the extinguishing agent is sprayed out from the nozzle 305, and the extinguishing agent sprayed from the nozzle 305 comes into contact with the fire. Upon reaching the truncated cone 312, the extinguishing agent passes through the inclined diverter plate 3132 again, where it is dispersed. Some of the extinguishing agent passes through the space 3133 to extinguish the fire on the battery pack. The linear module 301 drives the connecting plate A302 to move laterally back and forth, and the connecting plate B303 moves along the guide rod 310, causing the nozzle 305 to move back and forth. The telescopic tube 307 extends and retracts accordingly, and the nozzle 305 sprays the extinguishing agent to extinguish the fire on the battery pack.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
