Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, and in particular to a fireproof device for commercial energy storage cabinets. Background Technology

[0002] Energy storage cabinets are the basic unit of energy storage equipment. A single energy storage cabinet can store a huge amount of electricity every day, essentially functioning as a large power bank. The internal cavity houses stacked energy storage battery packs for convenient daily battery swapping. However, a fireproof energy storage cabinet, as described in patent application CN220967937 U, uses internally layered partitions for storage and positioning. It lacks a square isolation frame connecting the insulation cotton filling layer, and cannot form a separate cavity to isolate the battery packs. This makes them prone to interconnection, affecting safety. Furthermore, it cannot accurately locate and extinguish fires, resulting in low efficiency and insufficient stability. Therefore, we propose a fireproof device for commercial energy storage cabinets. Utility Model Content

[0004] This utility model discloses a fireproof device for a commercial energy storage cabinet, comprising a cabinet body, a fixed plate fixedly connected inside the cabinet body, a partition fixedly connected to the front side of the fixed plate, a storage cavity formed inside the partition, a square isolation frame fixedly connected to the inner side of the storage cavity, a heat insulation cotton filling layer provided between the square isolation frame and the partition, a connecting seat and a nozzle fixedly connected inside the square isolation frame, and a fireproof structure provided at the rear side of the cabinet body. The fireproof structure includes a storage tank and a fixed pipe fixedly connected to the bottom of the storage tank. The storage tank is fixedly installed at the upper end of the cabinet body, the fixed pipe is fixedly connected to the back of the fixed plate, a branch pipe is fixedly welded to the side of the fixed pipe, and a solenoid valve is fixedly installed on the side of the branch pipe. The outlet of the solenoid valve is fixedly connected to the nozzle.

[0005] In the above scheme, the storage cavity has four layers, which are evenly distributed on the front surface of the fixed plate.

[0006] In the above scheme, both the branch pipe and the solenoid valve have four layers and are fixedly connected to the back of the fixing plate.

[0007] In the above scheme, a protective plate is hinged to the rear side of the cabinet, and a heat dissipation component is fixedly connected to one side of the protective plate. The heat dissipation component includes a fixed cylinder and a fan fixedly installed inside the fixed cylinder. The fixed cylinder is fixedly connected to the outer surface of the protective plate.

[0008] In the above scheme, a positioning ring is threaded onto the end of the fixed cylinder, and an annular positioning groove is provided on the inner side of the positioning ring.

[0009] In the above scheme, a breathable filter plate is pressed inside the annular positioning groove, and the breathable filter plate is located at the end of the fixed cylinder.

[0010] In the above scheme, a rotating rod is rotatably installed at the middle position of the air-permeable filter plate, and a cleaning scraper is fixedly connected to the surface of the rotating rod.

[0011] The advantages and beneficial effects of this utility model in the above solution are as follows: This utility model provides a fireproof device for a commercial energy storage cabinet. By connecting the partition with the fixed plate inside the cabinet, a separate storage cavity is formed. Combined with the square isolation frame and the heat insulation cotton filling layer, the battery pack can be stored separately, which is conducive to separating them and reducing mutual influence.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1-5 As shown, this utility model is a fireproof device for a commercial energy storage cabinet, including a cabinet body 1. A fixed plate 11 is fixedly connected inside the cabinet body 1. A partition 12 is fixedly connected to the front side of the fixed plate 11. A storage cavity 13 is formed inside the partition 12. The partition 12, which is connected longitudinally and laterally, can separate independent storage cavities 13. When one location heats up, it will not affect other locations, resulting in high safety and stability. Each space can be equipped with a cabinet door for easy opening and replacement of the battery pack. It can be used for commercial battery swapping and has high adaptability. A square isolation frame 14 is fixedly connected to the inner side of the storage cavity 13. A heat insulation cotton filling layer 15 is provided between the square isolation frame 14 and the partition 12. The square isolation frame 14 forms a double-layer structure, and the heat insulation cotton filling layer 15 is positioned inside the gap, which can improve the heat insulation effect and further reduce mutual interference, ensuring safety and stability. A connecting seat 16 and a nozzle 17 are fixedly connected inside the square isolation frame 14. The connecting seat 16 can be connected to the back wire, which facilitates the connection of the battery. The battery pack is charged, while the nozzle 17, combined with a sensor, detects high temperature and then individually controls the spraying of carbon dioxide or foam for fire extinguishing, improving fire resistance and facilitating combined use. The rear of the cabinet 1 is equipped with a fireproof structure 2, which includes a storage tank 21 and a fixed pipe 22 fixedly connected to the bottom of the storage tank 21. The storage tank 21 is fixedly installed at the top of the cabinet 1. The installation of the storage tank 21 at the top position facilitates external maintenance and timely replenishment of fire extinguishing materials. The fixed pipe 22 is fixedly connected to the back of the fixed plate 11. A branch pipe 23 is fixedly welded to the side of the fixed pipe 22. A solenoid valve 24 is fixedly installed on the side of the branch pipe 23. The solenoid valve 24 is connected in parallel to the control board through a circuit and uniformly installed on the back of the fixed plate 11. It can be separated from the front battery pack, which is safe and easy to control. The outlet of the solenoid valve 24 is fixedly connected to the nozzle 17. The storage tank 21 can store different types of fire extinguishing materials and can be electrically controlled to open, so that the nozzle 17 sprays out to cool and extinguish the fire, improving the fire resistance effect.

[0021] In practical use, the cabinet 1 can be installed outdoors. The battery pack can be stored separately in the storage cavity 13, or it can be charged and stored by connecting the charging head with the connector 16. This makes it convenient for users to replace the battery pack separately, which is conducive to commercial operation. When some parts malfunction and overheat, the solenoid valve 24 at the corresponding position can be opened to spray fire extinguishing material directly into the separate storage cavity 13. After filling the storage cavity 13, the external air is isolated. On the one hand, it can extinguish the fire directly, and on the other hand, it can reduce the impact on other parts, reduce maintenance costs, and facilitate combined use.

[0022] Furthermore, the storage cavity 13 has four layers, which are evenly distributed on the front surface of the fixing plate 11.

[0023] Furthermore, both the branch pipe 23 and the solenoid valve 24 have four layers and are fixedly connected to the back of the fixing plate 11. By setting up a multi-layer structure, they can correspond to the interior of the corresponding storage cavity 13, which is conducive to individual control for fire extinguishing.

[0024] Furthermore, a protective plate 25 is hinged to the rear side of the cabinet 1, and a heat dissipation component 3 is fixedly connected to one side of the protective plate 25. The heat dissipation component 3 includes a fixed cylinder 31 and a fan 32 fixedly installed inside the fixed cylinder 31. The fixed cylinder 31 is fixedly connected to the outer surface of the protective plate 25. The heat dissipation component can be connected and positioned at the back through the protective plate, and can blow air to cool the inside. Combined with the fixed plate 11 to carry out large-area heat exchange, it can cool and protect the storage cavity 13 on the front side, which is highly safe.

[0025] Furthermore, a positioning ring 33 is threaded onto the end of the fixed cylinder 31, and an annular positioning groove 34 is provided on the inner side of the positioning ring 33.

[0026] Furthermore, the annular positioning groove 34 has a permeable filter plate 35 pressed inside. The permeable filter plate 35 is located at the end of the fixed cylinder 31 and is installed on the fixed cylinder 31 by the positioning ring 33 thread. The permeable filter plate 35 can be installed by snapping it into the annular positioning groove 34. On the one hand, it filters the external air to prevent it from entering the interior and causing interference. On the other hand, it protects the position of the fan 32 to prevent damage and ensure safety and stability.

[0027] Furthermore, a rotating rod 36 is rotatably installed in the middle of the air-permeable filter plate 35, and a cleaning scraper 37 is fixedly connected to the surface of the rotating rod 36. The cleaning scraper 37 can clean the surface of the air-permeable filter plate 35, which is conducive to combined use.

[0028] In practical use, the protective plate 25 can be closed and locked to isolate and protect the back of the cabinet 1. The fan 32 can blow outside air into the cabinet 1 to cool the fixed plate 11. Excess air can flow out through the installation gaps for easy recycling. However, after prolonged air intake, some impurities may adhere to the breathable filter plate 35. During maintenance, the cleaning scraper 37 can be manually rotated along the surface of the breathable filter plate 35 to scrape and clean it, which is convenient and efficient. Alternatively, the positioning ring 33 can be removed, and the breathable filter plate 35 can be directly removed for all-round rinsing to avoid clogging and has high adaptability.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
