Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof equipment, in particular to a fire-extinguishing explosion-proof cabinet. Background Art

[0002] In the electronic product manufacturing industry where lithium batteries are core components, strict destructive testing of lithium batteries is a vital link. These tests include high temperature, low temperature, drop, overcharge, over discharge and other extreme conditions to ensure that the battery can maintain stable performance in various environments. However, the batteries after these tests often have certain safety hazards, such as possible risks of smoke and fire.

[0003] The traditional practice is to place the tested battery directly into an explosion-proof cabinet. Although this measure can control potential safety risks to a certain extent, it also brings a series of new problems. On the one hand, if the battery catches fire in the explosion-proof cabinet, it is likely to ignite other products in the cabinet, which will not only interfere with the ongoing tests of other products, but may also cause a chain reaction and cause greater safety hazards. On the other hand, once a deflagration occurs in the explosion-proof cabinet, it is often only possible to passively wait for the fire to extinguish naturally before observation and recording can be carried out. This undoubtedly increases the difficulty of data collection, and is also not conducive to quickly determining the specific location of the fire source, which has a serious impact on the analysis and evaluation of the test results. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a fire-extinguishing explosion-proof cabinet to solve the problem that a fire of a battery in an explosion-proof cabinet may ignite other products in the cabinet, which may not only interfere with the ongoing tests of other products, but may also cause a chain reaction and lead to greater safety hazards. Once a deflagration occurs in the explosion-proof cabinet, observation and recording can only be carried out passively after the fire is naturally extinguished, which undoubtedly increases the difficulty of data collection and is not conducive to quickly determining the specific location of the fire source, thereby having a serious impact on the analysis and evaluation of the test results.

[0014] As a preferred technical solution of the present utility model, a plurality of storage cavities are divided in the first storage box, and the storage cavities correspond to the first discharge ports one by one.

[0015] As a preferred technical solution of the utility model, the storage cavity is in a funnel shape near the first discharge port, the diameter of which gradually decreases from top to bottom.

[0016] Compared with the prior art, in the fire-extinguishing and explosion-proof cabinet of the present invention, when the tested batteries or products are placed in the first storage slot, if a fire occurs in a battery or product in a certain first storage slot, the temperature rise will trigger the fire source reaction fire extinguishing device at the corresponding first discharge port.

[0033] See also Figures 1 to 5 The embodiment of the utility model discloses a fire-extinguishing and explosion-proof cabinet, which includes: a cabinet body 1, a first storage layer 11 is provided in the cabinet body 1, a plurality of first storage grooves 111 are provided on the first storage layer 11, a first storage box 12 is provided above the first storage layer 11, the first storage box 12 is used to store materials for fire extinguishing, the first storage box 12 is provided with a plurality of first discharge ports 121 on one side of the first storage layer 11, the first discharge ports 121 correspond to the first storage grooves 111 one by one, a fire source reaction fire extinguishing device 2 is provided at the first discharge port 121, when a fire occurs in the first storage groove 111, the fire source reaction fire extinguishing device 2 of the first discharge port 121 corresponding to the first storage groove 111 above the first storage groove 111 responds, so that the first discharge port 121 is changed from a blocked state to a conducting state.

[0034] It should be explained that the fire source reaction fire extinguishing device 2 is a temperature-sensitive trigger mechanism. When a fire occurs in the lithium battery in the first storage slot 111, the temperature will rise rapidly. When the temperature reaches the preset threshold of the fire source reaction fire extinguishing device 2, the device will respond, so that the originally blocked first discharge port 121 is turned on, thereby releasing the fire extinguishing material and quickly extinguishing the burning lithium battery. Optionally, the fire extinguishing material stored in the first storage box 12 can be sand, dry powder, foam fire extinguishing agent, etc. In this embodiment, the fire extinguishing material stored in the first storage box 12 is sand.

[0035] Furthermore, a second storage layer 13 is provided in the cabinet body 1, and a plurality of second storage grooves 131 are provided on the second storage layer 13. A second storage box 14 is provided above the second storage layer 13. The second storage box 14 is used to store materials for fire extinguishing. The second storage box 14 is provided with a plurality of second discharge ports 141 on the side facing the second storage layer 13. The second discharge ports 141 correspond one-to-one to the second storage grooves 131, and a fire source reaction fire extinguishing device 2 is provided at the second discharge port 141; the second storage layer 13 and the second storage box 14 are located below the first storage layer 11, or the second storage layer 13 and the second storage box 14 are located above the first storage box 12.

[0036] In this embodiment, the second storage layer 13 and the second storage box 14 are added. The second storage layer 13 and the second storage box 14 can be located below the first storage layer 11 to form a two-layer structure to increase the storage capacity of the cabinet 1. Alternatively, they can also be located above the first storage box 12 to form a stacked structure, making the entire cabinet 1 more compact in height, further improving the space utilization of the cabinet 1. Whether the lithium battery in the first storage slot 111 or the second storage slot 131 catches fire, the corresponding fire source reaction fire extinguishing device 2 will respond quickly and release fire extinguishing materials to extinguish the fire.

[0037] Specifically, when designing a fire-proof and explosion-proof cabinet, the volume of the second storage tank 131 is larger or smaller than the volume of the first storage tank 111, taking into account the diversity of test requirements. It is understandable that the specific size of the volume depends on the actual application scenario and test requirements. For example, if the test needs to accommodate larger-sized lithium batteries, the volume of the second storage tank 131 will be designed to be relatively large; conversely, if small lithium batteries are mainly tested, the volume can be reduced accordingly. In short, the first storage tank 111 and the second storage tank 131 with different volume sizes can accommodate more test objects of different models and sizes.

[0038] Specifically, the fire source reaction fire extinguishing device 2 is a fusible alloy, which is an alloy material with a low melting point. When a fire occurs in the lithium battery in the first storage slot 111 or the second storage slot 131 and the temperature rises rapidly, the fusible alloy will melt rapidly, causing the originally blocked first discharge port 121 or the second discharge port 141 to become conductive. Once the first discharge port 121 or the second discharge port 141 is conductive, the fire extinguishing material in the first storage box 12 or the second storage box 14 will be sprayed onto the burning lithium battery, thereby achieving rapid fire extinguishing.

[0039] Further, the cabinet body 1 is provided with a cabinet door 3, the first storage box 12 is movably arranged in the cabinet body 1, and a handle 122 is provided on the side of the first storage box 12 facing the cabinet door 3. It can be understood that the first storage box 12 is movably arranged in the cabinet body 1, that is, the first storage box 12 can be taken out or put back from the cabinet body 1, and the user can easily check and replace the fire extinguishing materials in the first storage box 12. The first storage box 12 is provided with a handle 122 on the side facing the cabinet door 3, so that the user can easily pull out or push in the first storage box 12 through the handle 122. Optionally, the second storage box 14 is also movably connected to the cabinet body 1, and a handle 122 is provided on it.

[0040] Specifically, the first storage box 12 is slidably connected to the cabinet 1. The sliding connection makes it easy and quick to access the first storage box 12. The user only needs to gently pull the first storage box 12 to slide it out, which is convenient for checking, replenishing or replacing the fire extinguishing materials therein.

[0041] Specifically, the first storage box 12 is provided with a feeding port connected to the interior of the first storage box 12, and the feeding port is used to replenish or add fire extinguishing materials into the first storage box 12. Optionally, the feeding port is arranged on the top of the first storage box 12, so that the user can perform the feeding operation.

[0042] Furthermore, the cabinet body 1 is made of stainless steel flame retardant material, which has excellent flame retardant properties and can maintain its structural stability at high temperatures, effectively preventing the spread of fire. This is crucial for fire-extinguishing and explosion-proof cabinets that store flammable and explosive items, and can reduce the risk of fire to a certain extent.

[0043] Furthermore, a plurality of storage cavities 123 are separated in the first storage box 12 , and the storage cavities 123 correspond to the first discharge ports 121 one by one.

[0044] Specifically, the storage cavity 123 near the first discharge port 121 is in a funnel shape with a diameter gradually decreasing from top to bottom.

[0045] In this embodiment, the portion of the storage cavity 123 near the first discharge port 121 is funnel-shaped, that is, the diameter gradually decreases from top to bottom, which helps the material flow to the first discharge port 121 more smoothly under the action of gravity, ensuring that the fire-extinguishing material can be released quickly and effectively when needed.

[0046] Compared with the prior art, in the fire-extinguishing and explosion-proof cabinet of the present invention, when the tested batteries or products are placed in the first storage slot, if a fire occurs in a battery or product in a certain first storage slot, the temperature rise will trigger the fire source reaction fire extinguishing device at the corresponding first discharge port. After the fire source reaction fire extinguishing device responds, the first discharge port changes from a blocked state to a conductive state, and the fire extinguishing material in the first storage box is directly sprayed onto the battery or product on fire through the first discharge port, thereby quickly controlling the fire, reducing the risk of igniting other products due to the fire of the battery or product, and reducing the possibility of a chain reaction. Since the fire is controlled in time, data collection and result analysis can be more convenient, thereby improving the accuracy and reliability of the test results.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
