Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage systems, in particular to an energy storage cabinet with fire explosion prevention device. BACKGROUND

[0002] At present, energy storage systems are widely used in various power and industrial scenarios. As a core component, the energy storage cabinet usually contains a large number of battery modules for storing and releasing electrical energy. Although the existing energy storage cabinet considers the conventional protection of the battery in the design, such as temperature sensor, smoke alarm and other safety measures, these designs mainly focus on the monitoring and basic protection of the equipment during daily operation, and do not fully consider the fire and explosion risks that may occur in extreme situations. When the battery fails such as thermal runaway, high temperature and high pressure gas may be generated inside the energy storage cabinet. If these conditions cannot be effectively controlled, fire or explosion may occur, which may cause serious damage to the equipment and the surrounding environment.

[0003] The traditional energy storage cabinet is difficult to provide effective pressure release and temperature control in such fire or explosion emergencies. Since the energy storage cabinet is usually designed to be sealed, once a fire occurs, the pressure and temperature inside the cabinet body can easily accumulate, and there is a lack of sufficient channels to quickly release these pressures, which may lead to an explosion and thus expand the loss. On the other hand, since the fire often spreads from the battery module upwards, the top cover of the traditional energy storage cabinet does not have an effective fire extinguishing channel at the initial stage of the fire, and it is difficult to quickly pour fire extinguishing liquid or coolant through the top to control the fire. This design deficiency makes the existing energy storage cabinet unable to timely and effectively handle emergency situations in the face of fire and explosion. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to at least overcome one deficiency of the prior art, and to provide an energy storage cabinet with a fire explosion prevention device. When a fire or explosion occurs inside the energy storage cabinet, the high pressure gas can be effectively released, and a convenient top channel is provided for fire extinguishing operations, thereby improving the safety and emergency handling capability of the energy storage cabinet in extreme situations.

[0005] To achieve the above-mentioned purpose, the present application discloses an energy storage cabinet with a fire explosion prevention device, which comprises a cabinet body and a fire explosion prevention device arranged on the top surface of the cabinet body.

[0006] Among them, the top surface of the cabinet body is provided with an opening matched with the explosion-proof device, and the explosion-proof device seals the opening. During the operation of the energy storage cabinet, when a fire or explosion occurs, the explosion-proof device can quickly release the high pressure gas accumulated inside the cabinet body, thereby effectively preventing more serious accidents caused by excessive internal pressure.

[0007] The structure of the explosion-proof device comprises a first fixing member and a second fixing member fixed on the top surface of the cabinet body, and the explosion-proof cover plate is hinged to the first fixing member through a rotating shaft member.

[0008] The rotating shaft member is installed between the first fixing member and the explosion-proof cover plate, and the rotating shaft member can enable the explosion-proof cover plate to be flipped open under the action of a certain pressure. The other side of the explosion-proof cover plate is provided with an elastic buckle which is matched with a buckle position on the second fixing member, thereby firmly constraining the other side of the explosion-proof cover plate on the second fixing member, so as to ensure that the explosion-proof cover plate is stably sealed to the opening under normal circumstances.

[0009] Further, the first fixing member is provided with a limiting plate matched with the explosion-proof cover plate. The limiting plate functions to limit the downward range of the explosion-proof cover plate, and provides support force for the closed explosion-proof cover plate.

[0010] In the preferred embodiment, the rotating shaft member is made of plastic material which can be hot-melted under high-temperature environment, and the hot-melt temperature is lower than 200 degrees. The plastic material can be melted after the fire occurs, thereby avoiding the situation that the rotating shaft member is stuck or cannot be opened due to excessively high temperature.

[0011] Through the application of the hot-melt plastic, the rotating shaft member can smoothly open the explosion-proof cover plate under the condition of fire or explosion, and rapidly release the high-pressure gas accumulated in the cabinet body, thereby effectively reducing the danger caused by the fire or explosion.

[0012] The explosion-proof device of the present application is designed with precise structure, so that the energy storage cabinet can timely release the high-pressure gas in the interior when the fire or explosion occurs, thereby providing a convenient passage for fire extinguishing operation. The design of the explosion-proof device not only enhances the safety of the energy storage cabinet under extreme conditions, but also ensures the reliability of the device in normal use, and improves the overall emergency handling capability of the energy storage cabinet.

[0013] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation manners will be further disclosed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0023] Understood, I will add a label to each component according to your requirements, and the following is the updated embodiment: EMBODIMENT

[0024] The present embodiment describes in detail a kind of energy storage cabinet 1 with fire explosion-proof device, the energy storage cabinet 1 is designed to meet the requirements of high-pressure gas release and fire extinguishing operation of energy storage system in fire or explosion situation.The explosion-proof device design of energy storage cabinet 1 can effectively deal with the fire or explosion risk caused by battery module failure of energy storage system, and provide reliable pressure release and fire extinguishing passage in extreme case.The structure, connection relationship between each component, working principle and implementation technology of energy storage cabinet 1 will be described in detail as follows.

[0025] Referring to the drawings Figure 1The main body of the energy storage cabinet is the cabinet body 1, which is mainly composed of metal alloy materials or composite materials, ensuring sufficient strength and structural stability to withstand internal and external pressure changes in high temperature and high pressure environments. An opening (not shown in the figure) is provided on the top of the cabinet body 1 to cooperate with the explosion-proof device 2. The position and size of the opening are accurately designed to ensure that the explosion-proof device 2 can timely release the internal accumulated pressure. The design of the opening enables the explosion-proof device 2 to smoothly open in the case of high temperature or explosion, thereby avoiding explosion or deformation of the cabinet body 1 due to excessive pressure.

[0026] Referring to the accompanying drawings Figures 1-3 In this embodiment, the main structure of the explosion-proof device 2 includes a first fixing member 4 fixed on the top surface 3 of the cabinet body 1, a second fixing member 5, and an explosion-proof cover plate 6 connecting these components. The explosion-proof cover plate 6 is hinged to the first fixing member 4 through a hinge member 7. In this embodiment, the hinge member 7 is made of plastic material that can melt under high temperature conditions. This design solves the problem that traditional metal hinge members may not open normally in high temperature environments. Specifically, the hinge member 7 can be made of high temperature resistant plastic materials such as polypropylene (PP) or polyethylene (PE), which can melt or soften under fire or explosion high temperature conditions, thereby avoiding jamming and enabling the explosion-proof cover plate 6 to open quickly to release high pressure gas.

[0027] The first fixing member 4 and the second fixing member 5 are fixed on the top surface 3 of the cabinet body 1 by bolts or welding, ensuring that the explosion-proof device 2 can be stably maintained in the specified position under normal use and fire conditions. The first fixing member 4 is usually made of high-strength metal alloy material, which has good high-temperature resistance and corrosion resistance to prevent failure in high-temperature or corrosive environments. The second fixing member 5 is provided with a buckle position for cooperating with the elastic buckle 8, ensuring that the explosion-proof cover plate 6 will not be accidentally opened due to external force or vibration under normal conditions.

[0028] The other side of the explosion-proof cover plate 6 is provided with an elastic buckle 8, which cooperates with the buckle position 9 on the second fixing member 5 to fix the explosion-proof cover plate 6 on the top surface 3 of the cabinet body 1. Under normal circumstances, the elastic buckle 8 firmly locks the explosion-proof cover plate 6 to prevent the cover plate 6 from loosening due to pressure at the opening or external influences. The buckle 8 is designed with elastic materials such as spring steel or high-strength plastic to ensure reliable elasticity and strength during long-term use. When a fire or explosion occurs, the gas pressure in the cabinet body 1 rapidly increases, and the elastic buckle 8 will be disconnected from the buckle position 9 due to the pressure, thereby causing the explosion-proof cover plate 6 to open quickly to release high pressure gas.

[0029] Further, the first fixing member 4 is provided with a limiting plate 10 cooperating with the explosion-proof cover plate 6. The limiting plate 10 limits the downward range of the explosion-proof cover plate 6 and provides support force for the closed explosion-proof cover plate 6. The limiting plate 10 ensures the stable fixation of the explosion-proof cover plate 6 after being closed by contacting the explosion-proof cover plate 6 and prevents the explosion-proof cover plate 6 from being accidentally opened or loosened due to external force or other factors.

[0030] The limiting plate 10 is usually made of high-strength metal material to ensure that it still provides sufficient strength and stability in a high-temperature and high-pressure environment, ensuring that the explosion-proof cover plate 6 can still be normally fixed under extreme conditions.

[0031] For the material selection of the rotating shaft member 7, the embodiment particularly selects a plastic material that can melt under high-temperature conditions. The core principle of this design is that when a fire or explosion occurs, the temperature in the area where the rotating shaft member 7 is located will rapidly rise. The traditional metal rotating shaft member may not work normally due to high-temperature expansion or hardening. The rotating shaft member 7 made of meltable plastic material can prevent the rotating shaft member 7 from being stuck by melting mechanism, ensuring that the explosion-proof cover plate 6 can be smoothly opened to release the pressure inside the energy storage cabinet 1. The selected plastic materials such as polypropylene (PP) and polyethylene (PE) have high melting points and good thermal stability, which can continue to maintain the melting or softening properties under high-temperature fire environment, and will not cause system failure due to local temperature rise.

[0032] In addition, the explosion-proof cover plate 6 of the explosion-proof device 2 is made of aluminum alloy or stainless steel material. The advantages of aluminum alloy or stainless steel are its good high-temperature resistance, corrosion resistance and strength, which can ensure that the explosion-proof cover plate 6 still maintains structural integrity when a fire or explosion occurs, and will not be broken or deformed. The stability of these materials in a high-temperature environment allows the explosion-proof cover plate 6 to be smoothly opened without being affected by the decline in material performance, thereby providing sufficient space for pressure release.

[0033] The explosion-proof device 2 in the energy storage cabinet of the embodiment not only can effectively release the high-pressure gas inside the energy storage cabinet, but also can provide a convenient entrance for fire extinguishing operation. When a fire or explosion occurs, the fire-fighting personnel can quickly inject fire extinguishing liquid or coolant into the energy storage cabinet through the top opening, thereby timely suppressing the fire and preventing the fire from spreading. The explosion-proof device 2 of the energy storage cabinet can be quickly opened at the initial stage of the fire, thereby effectively controlling the development of the fire and reducing the loss caused by the explosion or out-of-control of the energy storage cabinet.

[0034] For the technical content not described in detail in this embodiment, such as other components of the energy storage cabinet (such as the temperature control system, the protection circuit of the battery module, etc.), these parts belong to the common technical knowledge of those skilled in the art, and do not need to be further expanded in this embodiment. The focus of this embodiment is the specific design of the explosion-proof device 2 and its working principle, and to ensure that it has high efficient emergency response capability in extreme conditions such as fire explosion.

[0035] Overall, the explosion-proof device 2 of the energy storage cabinet provided in this embodiment can effectively deal with the high-pressure gas accumulated in the energy storage cabinet in the case of fire or explosion and provide a convenient channel for fire extinguishing operation by adopting a precisely designed structure and a rotating shaft member 7 with melting characteristics at high temperature. The design of the explosion-proof device 2 not only improves the safety performance of the energy storage cabinet, but also improves its stability and reliability under extreme conditions, providing a strong guarantee for the safe operation of the energy storage system in high-risk environments.

[0036] Although exemplary embodiments of the present disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims.
