Description

Technical Field

[0001] This utility model relates to the field of battery cabinet technology, and in particular to a fire protection device applied to a battery cabinet. Background Technology

[0002] With the rapid development of electric vehicles and the restriction of motorcycles in some cities, electric two-wheelers have become widespread. Each vehicle is equipped with at least one battery. Electric vehicle users need to charge the battery during use. However, the emergence of lithium battery charging and swapping cabinets allows users to continue riding simply by replacing the battery. The lithium batteries in the charging and swapping cabinets are shared components, and a single lithium battery may need to be charged multiple times a day. Lithium batteries are prone to fire during charging, and since there are multiple lithium batteries in the charging and swapping cabinet, if one lithium battery catches fire, the fire can spread and cause a greater safety hazard. Therefore, fire-fighting equipment is provided.

[0003] In existing technology, when a battery catches fire, a smoke detector will generally detect it and trigger a fire extinguisher to extinguish the fire inside the battery cabinet. However, although this method of extinguishing the fire is effective, it cannot accurately locate the fire point and may damage other components inside the battery cabinet. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where, when a battery catches fire, a smoke alarm typically detects it and triggers a fire extinguisher to extinguish the fire inside the battery cabinet. However, while this method extinguishes the fire, it cannot accurately pinpoint the extinguishing point and may damage other components inside the battery cabinet. Therefore, this invention proposes a fire-fighting device for use in battery cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fire-fighting device for a battery cabinet includes a cabinet, a plurality of charging bases installed inside the cabinet, a plurality of charging slots for charging batteries inside each charging base, a cabinet door corresponding to each charging slot on the outside of the cabinet, and a smoke sensor installed inside the cabinet. The fire-fighting device for a battery cabinet further includes: The mobile positioning mechanism includes a positioning seat correspondingly installed on the upper part of each of the charging seats, a spray plate movably disposed between the positioning seat and the charging seat, and a nozzle fixed to the bottom of the spray plate for extinguishing fire sources. The spray plate is connected to a fire extinguishing device through an air supply pipe. A fire source tracker is provided at the bottom of the spray plate. A positioning screw is rotatably disposed inside the positioning seat. A moving block connected to the spray plate is sleeved on the positioning screw. The moving block has a threaded hole along its length that engages with the positioning screw. A drive component connected to the positioning screw and used to drive the mobile positioning mechanism to track the fire source is installed on the positioning seat.

[0006] Furthermore, the driving assembly includes a driving rod rotatably disposed within the positioning seat, with a first bevel gear and a second bevel gear respectively fixedly fixed at one end of the driving rod near the positioning screw, and a driving motor connected to the driving rod mounted on the positioning seat.

[0007] Furthermore, a limiting block is slidably installed between the top of the moving block and the top wall of the positioning seat for moving the moving block horizontally along the positioning seat under the drive of the positioning screw.

[0008] Furthermore, the fire extinguishing device is a carbon dioxide gas cylinder fixed to one side of the cabinet and connected to the spray plate via a gas supply pipe, and the gas supply pipe is equipped with a solenoid valve.

[0009] Furthermore, the gas transmission pipe is a two-way pipe, and each branch of the two-way pipe is equipped with a one-way valve.

[0010] Furthermore, each of the charging docks has heat dissipation holes at its bottom corresponding to the charging slot.

[0011] Compared with the prior art, the advantages of this utility model are: 1. In this solution, the smoke sensor and the fire source tracker on the spray plate work together. Once the battery spontaneously combusts, both sensors will detect the fire and send signals to the controller, enabling the controller to accurately know the fire situation and the specific ignition point (i.e., the location of the spontaneously combusting battery in the charging slot). Compared with the existing technology that relies solely on the smoke alarm, this greatly improves the accuracy of fire source location. 2. After receiving the signal, the controller of this solution drives the motor to run. With the meshing of the first and second bevel gears, the engagement of the positioning screw and the threaded hole, and the limiting action of the limit block on the moving block, the spray plate can be accurately moved to the fire source position for positioning. This ensures that the subsequent fire extinguishing action is aimed at the exact ignition point and avoids damage to other components caused by blind fire extinguishing. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] Compared to existing technologies, this application, through a mobile positioning mechanism and a drive component, enables the drive component to precisely locate the fire source, ensuring that subsequent fire extinguishing actions target the exact point of origin and avoiding damage to other components caused by indiscriminate fire suppression. For details, please refer to... Figure 2 As shown, a fire protection device applied to a battery cabinet 1 includes a cabinet 1, a plurality of charging bases 3 are installed inside the cabinet 1, a plurality of charging slots for charging batteries are provided inside the charging bases 3, and a heat dissipation hole 301 is provided at the bottom of each charging base 3 corresponding to the charging slot. A cabinet door 5 is provided on the outside of the cabinet 1 corresponding to each charging slot, and a smoke sensor 7 is provided inside the cabinet 1.

[0017] As described above, the heat generated when the battery is charging in the charging slot can be smoothly dissipated through the heat dissipation hole 301, which helps to maintain a reasonable temperature environment inside the battery and cabinet 1, ensure the normal operation of the equipment, and extend the service life of related components.

[0018] Better, such as Figure 1 and Figure 2As shown, a fire-fighting device applied to a battery cabinet 1 further includes: a mobile positioning mechanism, including a positioning seat 2 correspondingly installed on the upper part of each charging base 3, a spray plate 203 movably disposed between the positioning seat 2 and the charging base 3, and a nozzle 204 fixed at the bottom of the spray plate 203 for extinguishing fire sources. The spray plate 203 is connected to a fire extinguishing device through a gas supply pipe 205. A fire source tracker 208 is provided at the bottom of the spray plate 203. A positioning screw 201 is rotatably disposed inside the positioning seat 2. A moving block 202 connected to the spray plate 203 is sleeved on the positioning screw 201. The moving block 202 has a threaded hole along its length that engages with the positioning screw 201. The fire extinguishing device is a carbon dioxide gas cylinder 210 fixed on one side of the cabinet 1 and connected to the spray plate 203 through the gas supply pipe 205. A solenoid valve 206 is provided on the gas supply pipe 205. The gas supply pipe 205 is a two-way pipe, and a one-way valve 207 is provided on each branch of the two-way pipe.

[0019] As described above, the spray plate 203 moves with the moving block 202, and the fire source location can be accurately located using the fire source tracker 208. The fire source tracker 208 is model ZDMS0.6 / 5S, and other devices with precise temperature measurement infrared thermal imaging lenses and high-definition visible light cameras can also be used. The solenoid valve 206 and the one-way valve 207 are opened, allowing the gas in the carbon dioxide cylinder 210 to be delivered to the spray plate 203 through the gas supply pipe 205. The gas is then sprayed towards the fire source location by the nozzle 204, thereby achieving precise fire extinguishing. This avoids spraying large amounts of fire extinguishing materials and prevents the fire from spreading and damaging other components inside the cabinet 1. The fire extinguishing device here is not limited to the carbon dioxide cylinder 210; aerosol fire extinguishers, fire extinguishers, and heptafluoropropane fire extinguishers can also be used.

[0020] Better, such as Figure 2 and Figure 3 As shown, a drive assembly connected to the positioning screw 201 is installed on the positioning base 2 to drive the moving positioning mechanism to track the fire source. The drive assembly includes a drive rod 4 rotatably disposed in the positioning base 2. A first bevel gear 401 and a second bevel gear 402 are respectively fixed and meshed at one end of the drive rod 4 near the positioning screw 201. A drive motor connected to the drive rod 4 is installed on the positioning base 2. A limiting block 209 is slidably installed between the top of the moving block 202 and the top wall of the positioning base 2 to make the moving block 202 move in the horizontal direction of the positioning base 2 under the drive of the positioning screw 201.

[0021] As described above, the output shaft of the drive motor begins to rotate, which in turn drives the connected drive rod 4 to rotate synchronously. Thanks to the precise meshing between the first bevel gear 401 and the second bevel gear 402, the positioning screw 201 rotates along with it. Because the positioning screw 201 is tightly screwed into the threaded hole, and the limit block 209 accurately limits the movement block 202, it is ensured that the movement block 202 can stably drive the spray plate 203 to move precisely towards the fire source and be positioned.

[0022] Better, such as Figure 1 , Figure 2 and Figure 3 As shown, a controller 6 is installed on the cabinet 1, which is connected to the solenoid valve 206, the check valve 207, the fire source tracker 208, and the smoke sensor 7.

[0023] Based on the above, when the smoke sensor 7 and the fire source tracker 208 locate the fire source, they send a signal to the controller 6, which then opens the solenoid valve 206 and the check valve 207 to release carbon dioxide gas for fire extinguishing.

[0024] The implementation principle of a fire-fighting device applied to a battery cabinet 1 according to an embodiment of this application is as follows: In actual operation, when it is necessary to remove the battery from the cabinet 1, simply open the corresponding cabinet door 5 to easily remove the battery placed in the charging slot. During the charging process of the battery in the charging slot, the heat generated can be effectively dissipated through the specially designed heat dissipation holes 301. If, unfortunately, the battery in the battery cabinet 1 spontaneously combusts, the sensitive smoke sensor 7 will quickly detect the abnormal situation and promptly transmit a signal to the controller 6; at the same time, the fire source tracker 208 equipped on the spray plate 203 will also accurately detect the location of the spontaneously combusting battery and similarly send a relevant signal to the controller 6.

[0025] Upon receiving these signals, the controller 6 immediately starts the drive motor. The output shaft of the drive motor begins to rotate, which in turn drives the connected drive rod 4 to rotate synchronously. Thanks to the precise meshing between the first bevel gear 401 and the second bevel gear 402, the positioning screw 201 rotates along with it. Because the positioning screw 201 is tightly screwed into the threaded hole, and the limit block 209 accurately limits the moving block 202, it is ensured that the moving block 202 can stably drive the spray plate 203 to move precisely towards the fire source and position it.

[0026] During this process, the controller 6 also simultaneously opens the solenoid valve 206 and the corresponding one-way valve 207 on the branch of the gas supply pipe 205. In this way, the gas stored in the carbon dioxide tank 210 is smoothly delivered along the gas supply pipe 205 to the spray plate 203, and then precisely and rapidly sprayed through the nozzle 204 to extinguish the fire. This design not only achieves a highly efficient fire extinguishing effect and effectively curbs the spread of the fire, but also greatly reduces the risk of damage to other components inside the battery cabinet 1, thereby mitigating potential losses to a certain extent.

[0027] It should be noted that in the existing technology, when a battery catches fire, the smoke alarm usually detects the fire and triggers a fire extinguisher to extinguish the fire in the entire battery cabinet. However, this traditional fire extinguishing method has obvious shortcomings, namely, it cannot accurately locate the fire point and can easily cause unnecessary damage to other components inside the battery cabinet during the fire extinguishing process.

[0028] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0029] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
