[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0031] Reference Figures 1-4 This utility model provides an embodiment of a forklift fire-fighting device, including an on-board battery assembly 1. The on-board battery assembly 1, as a primary power structure for new energy sources, reduces pollution, improves energy efficiency, is clean, and offers high economic benefits and lower operating costs. The on-board battery assembly 1, along with all other structures of this utility model, is installed inside the forklift drive bay. An on-board drive motor 2 is installed on the front of the on-board battery assembly 1 and connected to it via an electrical circuit. A storage frame 7 is installed on the left side of the on-board battery assembly 1, and a [missing information - likely a device name or component] is installed on the right side of the on-board battery assembly 1. A servo motor 8 is fixedly connected to a fan 10 at its drive end. Smoke sensors 3 and temperature sensors 4 are respectively installed on the front left and right sides of the vehicle battery assembly 1. A refrigeration box 6 is embedded in the inner wall of the top of the storage frame 7. A refrigeration plate is installed inside the refrigeration box 6 to lower the internal temperature to the minimum in order to preserve liquid carbon dioxide. Limiting components are provided on the inner walls of the front and rear sides of the storage frame 7. An electronically controlled exhaust valve 5 is installed on the right end of the refrigeration box 6. Locking blocks 9 are fixedly connected to the lower right side of both the front and rear ends of the refrigeration box 6. Limiting holes 16 are opened on the left end of each locking block 9.

[0032] Specifically, the smoke sensor 3 and the electronically controlled exhaust valve 5 are respectively connected to the externally installed processor via circuits. When the vehicle battery pack 1 and the vehicle drive motor 2 catch fire, the smoke generated will be detected by the smoke sensor 3. At this time, the smoke sensor 3 transmits an electrical signal to the processor, and then the processor controls the electronically controlled exhaust valve 5 to open, so that the air inside and outside the refrigeration box 6 can circulate. The liquid carbon dioxide in the refrigeration box 6 vaporizes and is discharged around the vehicle battery pack 1 and the vehicle drive motor 2 to extinguish the fire. The temperature sensor 4 and the servo motor 8 are respectively connected to the externally installed processor via circuits. When the temperature of the vehicle battery pack 1 or the vehicle drive motor 2 rises, the heat generated will cause the internal environment of the drive compartment to rise. At this time, after the temperature sensor 4 detects the temperature rise, it transmits an electrical signal to the processor. The processor then controls the servo motor 8 to start and rotate the fan 10 to blow air onto the vehicle battery pack 1 and the vehicle drive motor 2 to cool their surfaces and prevent the circuit components from burning due to excessive temperature.

[0033] Specifically, the limiting component includes a slider 15, the outer wall of which is slidably connected to the lower inner wall of the front and rear ends of the storage frame 7. A connecting plate 11 is fixedly connected to the top of each slider 15, and a pin 14 is fixedly connected to the right end of each connecting plate 11. The shape of the outer wall of the pin 14 matches the shape of the inner wall of the limiting hole 16. A sliding rod 12 is slidably connected to the inner wall of each slider 15, and both ends of the sliding rod 12 are fixedly connected to the corresponding lower inner wall of the storage frame 7. A spring 13 is fixedly connected to the left end of each slider 15 near the outer side of the sliding rod 12, and the left end of the spring 13 is fixedly connected to the lower side of the storage frame 7. Corresponding to the inner wall, by pulling the connecting plate 11, the bottom slider 15 slides outward on the slide rod 12 and squeezes the spring 13. The connecting plate 11, with the plug 14, disengages from the limiting hole 16, releasing the limit on the locking block 9. Then, the refrigeration box 6 is taken out of the storage frame 7. The locking block 9 will disengage from the storage frame 7 through the notches on both sides of the storage frame 7, realizing the disassembly and removal of the refrigeration box 6 from the inside of the drive compartment. This facilitates the re-injection of liquid carbon dioxide into the refrigeration box 6 to prevent continued use in case of emergencies. The top of the plug 14 is respectively attached to the inner walls of the front and rear sides of the top of the storage frame 7.

[0034] Working principle: First, the smoke sensor 3 and temperature sensor 4 installed inside the drive compartment monitor the vehicle battery pack 1 and vehicle drive motor 2 in real time. When the temperature of the vehicle battery pack 1 or vehicle drive motor 2 rises, the heat generated will cause the internal environment of the drive compartment to rise. At this time, after the temperature sensor 4 detects the temperature rise, it transmits an electrical signal to the processor. The processor then controls the servo motor 8 to start and drive the fan 10 to rotate, blowing air onto the vehicle battery pack 1 and vehicle drive motor 2 to cool their surfaces and prevent the circuit components from burning due to overheating. When the vehicle battery pack 1 or vehicle drive motor 2 catches fire, the smoke generated will be detected by the smoke sensor 3. Sensor 3 transmits an electrical signal to the processor, which then controls the electronically controlled exhaust valve 5 to open, allowing air to circulate inside and outside the refrigeration box 6. The liquid carbon dioxide inside the refrigeration box 6 vaporizes and is discharged around the vehicle battery assembly 1 and the vehicle drive motor 2 to extinguish the fire. Afterward, by pulling the connecting plate 11, the bottom slider 15 slides outward on the slide rod 12 and squeezes the spring 13. The connecting plate 11, along with the plug 14, disengages from the limiting hole 16, releasing the locking block 9. The refrigeration box 6 is then removed from the storage frame 7, and the locking block 9 disengages from the storage frame 7 through the notches on both sides of the storage frame 7, thus enabling the refrigeration box 6 to be disassembled and removed from the drive compartment. This facilitates the re-injection of liquid carbon dioxide into the refrigeration box 6 to prevent continued use in case of emergencies.
