Description

Technical Field

[0001] This utility model relates to the field of battery box technology, and more specifically, to a battery box fire-fighting device. Background Technology

[0002] In existing battery box safety protection technologies, the system typically consists of a multi-layered physical protection structure, a status monitoring module, and a basic response mechanism. The main body of the battery box adopts a composite structure of a metal alloy shell and fireproof and heat-insulating materials. Internally, the battery cells are physically fixed and electrically isolated through a modular frame. Pressure relief valves, explosion-proof membranes, and other pressure release devices are also installed to cope with internal gas expansion. Patent document CN117815600A discloses a fire-fighting device and method for a containerized energy storage device. The fire-fighting device has fire-fighting components installed inside the box and a receiving cavity containing multiple battery boxes. Each battery box has a fire vent. The fire-fighting components include a primary unit, a secondary unit, and a tertiary unit. In the event of a fire, the first fire extinguisher of the primary unit sprays fire extinguishing water into the battery box through a fire extinguishing pipe. The induction wire of the secondary unit senses the temperature inside the box, and when it exceeds a target value, the second fire extinguisher activates to extinguish the fire. The sprinkler pipe of the tertiary unit is connected to fire-fighting water and sprays it into the box to extinguish the fire.

[0003] However, existing technologies suffer from delayed emergency response when safety incidents such as internal short circuits or thermal runaway occur in the battery pack. Temperature sensors only trigger alarms when a threshold is reached, and thermal runaway involves rapid temperature increases, resulting in an excessively short warning window. Gas detection is limited by sampling cycles and the time required for component analysis, making it difficult to determine the fault level promptly. Physical protection structures can only delay, not prevent, the spread of the accident. More critically, existing systems lack integrated rapid response modules; each safety component operates independently with linear response logic, failing to simultaneously initiate critical measures such as fire suppression, isolation, and cooling in the early stages of an accident, leading to low accident handling efficiency.

[0017] To address the problem of the inability to quickly move a battery box when it poses a safety hazard, this utility model has the following advantages:

[0018] A hollow, sealed chamber comprising a first chamber and a second chamber is formed by a frame assembly. This, combined with the structural linkage of the rotating and sliding units in the transfer assembly, enables the directional transfer and fire isolation of the battery box. When the battery box enters the first chamber, the transfer assembly is horizontal: the rotating plate, held horizontally by a limiting part, supports the battery box, while the sliding unit is fixed at an inclined angle inside the first chamber, with its height near the rotating unit greater than that near the fire-fighting assembly. When an emergency response is triggered, the limiting part disengages from the rotating plate, and the rotating plate, under its own weight, rotates around the sliding unit to an inclined position, causing the battery box to slide along the surface of the rotating plate to the inclined sliding unit surface, and then continues to move towards the second chamber under gravity. During this process, the first door unit closes to form a sealed chamber to prevent the spread of external fire, and the fire-fighting assembly simultaneously activates and releases extinguishing media into the second chamber. By combining the state switching of the rotating unit with the tilting angle of the sliding unit, the battery box can be quickly removed from the accident area and directionally transferred to the fire handling space. At the same time, the sealed chamber is used to physically isolate the accident battery box from the external environment, so that the battery box can be quickly reached the fire station for accident handling.

Unless otherwise stated, "a plurality of" means two or more.

[0028] In this embodiment, during the actual operation of the existing battery box fire suppression system, there is a functional defect in the structural fit between the frame assembly 01 and the transfer assembly 02. When the battery box enters the device, the horizontal state holding mechanism of the rotating unit 21 lacks a reliable triggering mechanism, causing the rotating plate 211 to fail to release the constraint of the limiting part 213 in a timely manner according to the emergency command, and the battery box remains in the first chamber and cannot initiate the transfer process. Figure 1As shown, this embodiment discloses a battery box fire-fighting device, which may include a frame assembly 01, a fire-fighting component 03, and a transfer component 02. The frame assembly 01 may include a frame unit 11 and a first door unit 12. The first door unit 12 may be movably connected to the frame unit 11. When the first door unit 12 is closed, the frame unit 11 and the first door unit 12 may form a hollow sealed chamber. The hollow sealed chamber may be divided into a first chamber and a second chamber. The first chamber may be located near the first door unit 12. The fire-fighting component 03 may be disposed in the second chamber. The transfer component 02 may be disposed in the first chamber. The transfer component 02 may include a rotating unit 21 and a sliding unit 22. The sliding unit 22 may be inclined. The height of the sliding unit 22 near the rotating unit 21 may be greater than the height of the side near the fire-fighting component 03. The rotating unit 21 may include a rotating plate 211 and a limiting part 213. The rotating plate 211 may be rotatably connected to the sliding unit 22. The transfer component 02 may have a horizontal state and a rotating state. In the horizontal state, the limiting part 213 abuts against the rotating plate 211 to keep the rotating plate 211 horizontal. In the rotating state, the limiting part 213 and the rotating plate 211 are spaced apart, and the rotating plate 211 can rotate around the sliding unit 22 under its own weight. The frame unit 11 and the first door unit 12 form a sealed chamber to divide the space area. The fire-fighting component 03 is set in the second chamber for centralized treatment. The transfer component 02 forms a battery box transfer channel by switching the state of the inclined sliding unit 22 and the rotating plate 211. After the limiting part is released, the rotating plate 211 rotates under its own weight to form an inclined guide surface. Combined with the slope design of the sliding unit 22, the battery box is directionally slidably transferred, which allows the battery box to be transferred quickly and ultimately solves the problem of low battery box transfer efficiency during emergency treatment. In some other embodiments, the rotating unit 21 may also include a rotating shaft 212 and a third driving part 214. The rotating shaft 212 may be connected to the sliding unit 22, and the rotating plate 211 may be rotatably connected to the sliding unit 22 via the rotating shaft 212. The third driving part 214 may be electrically connected to the limiting part 213, thereby controlling the state of the transfer component 02 through the limiting part 213.

[0029] In this embodiment, as Figure 2As shown, the sliding unit 22 may include a tilting platform 221 and a sliding plate 222. The tilting platform 221 may be connected to the sliding plate 222. The tilting platform 221 may be tilted. The tilting platform 221 may be connected to the frame unit 11. The height of the tilting platform 221 near the rotating unit 21 may be greater than the height near the fire-fighting component 03. The rotating plate 211 may be rotatably connected to the tilting platform 221. The rotating state may include a limiting part 213 spaced apart from the rotating plate 211, and the rotating plate 211 may rotate around the tilting platform 221 under its own weight. At the same time, when the battery box is placed on the rotating plate 211, the center of gravity of the battery box will also shift relative to the rotation axis towards the side closer to the fire-fighting component 03, thereby allowing the battery box to further increase its transfer speed under its own weight, realizing rapid transfer of the battery box. The tilting platform 221 and the sliding plate 222 form a continuous tilting surface to provide a stable sliding base. The rotating plate 211 rotates around the tilting platform 221 to form a switchable receiving transition structure. Through the height difference design, the battery box moves along the tilting platform 221 towards the fire-fighting component 03 under the action of gravity, and finally realizes the efficient transfer of the accident battery box from the receiving position to the processing position.

[0030] In this embodiment, as Figure 3 As shown, the first door unit 12 may include a first movable door 121 and a first drive unit 122. The first movable door 121 may be drivenly connected to the first drive unit 122. The first movable door 121 may be movably connected to the frame unit 11. When the first movable door 121 is closed, the frame unit 11 and the first movable door 121 may form a hollow sealed chamber. The first chamber may be close to the first movable door 121. The drive unit controls the opening and closing of the movable door to form a variable sealing structure. When open, it provides an inlet channel for the battery box. When closed, it cooperates with the frame unit 11 to construct a closed processing space, effectively blocking the external environment and the accident area.

[0031] In this embodiment, as Figure 5 As shown, the frame assembly 01 may further include a second door unit 13. The second door unit 13 may include a second movable door 131 and a second drive unit 132. The second movable door 131 may be drivenly connected to the second drive unit 132. The second movable door 131 may be movably connected to the frame unit 11. When the first movable door 121 and the second movable door 131 are closed, the frame unit 11, the first movable door 121, and the second movable door 131 may form a hollow sealed chamber. The second chamber may be located close to the second movable door 131. The second door unit 13 and the first door unit 12 work together to construct a bidirectional sealing system. After processing, the second movable door 131 is opened to form a safe exit, preventing the processed battery box from contaminating the operating area.

[0032] In this embodiment, as Figure 2As shown, the fire-fighting component 03 may include a receiving unit 31 and a fire-fighting unit 32. The receiving unit 31 may be connected to the frame unit 11. The fire-fighting unit 32 may be connected to the frame unit 11, and the receiving unit 31 and the frame unit 11 may be spaced apart to form a fire-fighting space. The receiving unit 31 provides a battery box positioning and support function, and the spatial separation design between the fire-fighting unit 32 and the receiving unit 31 forms an independent fire-fighting area, ensuring that the fire-fighting medium is concentrated on the target object.

[0033] In this embodiment, as Figure 1 As shown, the receiving unit 31 may include a receiving trolley 311, a fourth drive unit 312, a track 313, a locking part 314, and a first collecting part 315. The track 313 may be connected to the frame unit 11. The receiving trolley 311 may be movably connected to the track 313. The locking part 314 may be connected to the track 313. The first collecting part 315 may be connected to the track 313. The receiving trolley 311 may also include multiple first holes. The multiple first holes may penetrate the receiving trolley 311. The first collecting part 315 may be located below the first holes. The body of the receiving trolley 311 may be recessed towards the side near the track 313 to form a groove. The receiving unit 31 may include a receiving state, in which the battery box may be placed in the groove of the receiving trolley 311, and the locking part 314 may abut against the receiving trolley 311 to restrict its movement. When the battery box moves from the sliding unit 22 to the receiving trolley 311, the receiving trolley 311 can move on the track 313, allowing the battery box to enter the fire-fighting space for fire-fighting treatment. The track 313 cooperates with the drive unit to achieve directional movement of the receiving trolley 311, the groove structure provides stable support, the first hole and the collection unit form a waste liquid discharge channel, and the locking part 314 fixes the position of the receiving trolley 311 to ensure stable operation of the treatment process.

[0034] In this embodiment, the receiving unit 31 may further include a buffer pad 316. The buffer pad 316 may be disposed on the receiving trolley 311. One side of the buffer pad 316 may abut against the receiving trolley 311. The buffer pad 316 may include a plurality of second holes. The plurality of second holes may penetrate the buffer pad 316. During the movement of the battery box, the buffer pad 316 can absorb impact energy through elastic deformation, thereby enabling the battery box to move stably. The second holes keep the waste liquid flowing smoothly, and the dual-function design takes into account both protection performance and discharge efficiency.

[0035] In this embodiment, the fire-fighting unit 32 may include a first sensor 321, a second sensor 322, and a first fire extinguishing unit 323. The first sensor 321 may be connected to the frame unit 11. The second sensor 322 may be connected to the frame unit 11. The first sensor 321 may be a temperature sensor for detecting the temperature of the battery compartment. The second sensor 322 may be a smoke sensor for detecting the smoke concentration in the fire-fighting space. The first fire extinguishing unit 323 may be connected to the frame unit 11. The first sensor 321 may be electrically connected to the first fire extinguishing unit 323. The second sensor 322 may be electrically connected to the first fire extinguishing unit 323. The fire extinguishing state may include the first fire extinguishing unit 323 spraying fire extinguishing material into the fire-fighting space. In other embodiments, the fire-fighting unit 32 may also include a second fire extinguishing unit 324, which may spray a cooling medium to cool the battery compartment. Multiple sensors collaboratively detect fire parameters, triggering the first fire extinguishing unit 323 and the second fire extinguishing unit 324 to precisely spray the medium, achieving rapid response and automated processing through electrical signal linkage.

[0036] In this embodiment, the fire suppression component 03 may further include a gas handling unit 33. For example... Figure 4 As shown, the gas processing unit 33 may include a second collection unit 331 and a gas processor 332. The second collection unit 331 may be connected to the frame unit 11. The second collection unit 331 may be installed at the top of the fire-fighting space. The gas processor 332 may be connected to the frame unit 11. The top collection unit captures rising harmful gases, and the processor performs purification treatment to prevent the accumulation of toxic gases and secondary pollution.

[0037] In this embodiment, the frame unit 11 may include a frame 111 and a housing 112. The frame 111 may be connected to the housing 112. The housing 112 may be a hollow cavity. The frame 111 may be disposed within the hollow cavity. Figure 6 As shown, the first door unit 12 can be movably connected to the housing 112. When the first door unit 12 is closed, the housing 112 and the first door unit 12 can form a hollow sealed chamber. The frame 111 provides structural support strength, and the hollow design of the housing 112 forms a sealing boundary. This dual structure ensures the overall stability and airtightness of the device.

[0038] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
