Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, specifically a fire extinguishing device for an energy storage container. Background Technology

[0002] As is well known, existing fire extinguishing methods for energy storage batteries mostly use gaseous fire extinguishing agents such as heptafluoropropane and perfluorohexanone. Gas fire extinguishing can effectively extinguish open flames in energy storage batteries, but it has limited effect on cooling the batteries.

[0003] A search revealed a Chinese patent (publication number: CN219440521U) that discloses a fire extinguishing device for an energy storage container, including a high-pressure fine water mist system. This system can spray water at high pressure into an extremely fine mist, which has strong penetrability and can effectively extinguish open flames in energy storage batteries. In addition, water can absorb a large amount of heat during the vaporization process, and prolonged spraying can effectively reduce the temperature of the energy storage container, preventing further reactions inside the burning lithium battery, thereby effectively extinguishing the fire.

[0004] However, when the batteries inside the container are cooled by spraying, the water is subjected to high temperature and produces a large amount of steam, which increases the air pressure inside the container. Since the above-mentioned device is not equipped with an exhaust device, when the air pressure inside the container reaches a certain value, it will squeeze the container body and the door, causing them to deform and resulting in the container being scrapped. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a fire extinguishing device for energy storage containers, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fire extinguishing device for an energy storage container, comprising a container body, two double doors installed at the rear of the container body, multiple ventilation holes on the top of the container body, and an exhaust assembly mounted on the container body installed on the top of the ventilation holes, a fixing frame installed inside the exhaust assembly, a cover plate assembly slidably connected to the fixing frame, a spring fitted on the cover plate assembly, and a high-pressure fine water mist system and a water recovery system installed on the container body.

[0009] Furthermore, the exhaust assembly includes an exhaust pipe, the bottom of which is fixedly connected to a connecting ring.

[0010] Furthermore, the cover assembly includes a slide rod, one end of which is fixedly connected to a cap that matches the exhaust pipe, and the other end is connected to a connecting block, with a spring positioned between the connecting block and the fixing bracket.

[0011] Furthermore, the fixing frame includes a fixing block, a sliding hole in the middle of the fixing block, and multiple evenly distributed connecting rods connected to the inner wall of the exhaust pipe on the side wall.

[0012] Furthermore, the slide bar is a square bar and matches the sliding hole of the fixing block.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a fire extinguishing device for energy storage containers, which has the following beneficial effects:

[0015] 1. The fire extinguishing device for this energy storage container uses a spring to push the connecting block, which causes the sliding rod to close the cap on the exhaust pipe, preventing other substances from entering the container and protecting the battery clusters placed inside.

[0016] Second, the fire extinguishing device for this energy storage container, when the battery cluster is subjected to high temperature or combustion, the high-pressure fine water mist system extinguishes and cools the battery cluster. During this process, water forms steam, which increases the gas pressure inside the container. This can push the cap to detach from the exhaust pipe and discharge it outward, thereby reducing the internal air pressure of the container and preventing the internal air pressure from gradually increasing and damaging the container.

[0020] 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.

[0021] Please see Figure 1-2The present invention relates to an energy storage container fire extinguishing device, comprising a container body 1, with two double doors installed at the rear of the container body 1, a high-pressure fine water mist system 2 and a water recycling system 10 installed on the container body 1, and a battery cluster placed inside. The above is the prior art and will not be described in detail.

[0022] The top of the container body 1 has multiple ventilation holes, and an exhaust assembly 3 is installed on the top of the ventilation holes. The exhaust assembly 3 includes an exhaust pipe, and a connecting ring is fixedly connected to the bottom of the exhaust pipe. The inner diameter of the exhaust pipe is equal to the diameter of the ventilation hole. The connecting ring is connected to the top of the container body 1 by welding. When the high-pressure fine water mist system 2 sprays water to cool the battery cluster inside the container body 1, the steam formed by the heated water can be discharged outward along the exhaust pipe, causing the air pressure inside the container body 1 to be too high.

[0023] The exhaust pipe is equipped with a fixing frame 4. The fixing frame 4 includes a fixing block. The fixing block has a sliding hole in the middle and multiple evenly distributed connecting rods connected to the inner wall of the exhaust pipe on its side wall. The sliding rod 8 is a square rod that matches the sliding hole of the fixing block. A cover plate assembly 5 is slidably connected to the sliding hole. The cover plate assembly 5 includes a sliding rod 8. One end of the sliding rod 8 is fixedly connected to a cap 7 that matches the exhaust pipe, and the other end is connected to a connecting block 6. A spring 9 is fitted on the sliding rod 8 and is placed between the connecting block 6 and the fixing frame 4.

[0024] When the internal air pressure of container body 1 reaches a certain level, the gas can push the cap 7, which disengages from the exhaust pipe, causing the slide bar 8 to slide on the fixed frame 4. At the same time, the spring 9 is compressed, and the gas is discharged from the exhaust pipe, reducing the internal pressure of container body 1.

[0025] In summary, when the battery clusters overheat or burn, the high-pressure fine water mist system 2 sprays water onto the battery clusters inside the container 1 to cool them down and extinguish the fire. During this process, when the water encounters high temperature or burning substances, the water vaporizes, increasing the air pressure inside the container 1. The gas pushes the cap 7, causing it to detach from the exhaust pipe. At the same time, the slide rod 8 slides on the fixed frame 4, and the spring 9 mounted on the slide rod 8 is compressed by the connecting block 6.

[0026] When the battery cluster inside container 1 cools down or the fire is extinguished, the gas pressure inside container 1 decreases, the spring 9 gradually returns to its original shape, and pushes the connecting block 6, causing the slide rod 8 to drive the cap 7 to close the exhaust pipe, preventing rainwater or other substances from entering container 1 and protecting the battery cluster.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
