[0040] Currently, explosion venting devices in energy storage battery cabinets are typically designed at the top to prevent damage to the surrounding area in the event of an explosion. Simultaneously, to prevent environmental influence on the explosion venting device, a protective panel is often installed on it. The explosion venting device must rapidly release pressure in the event of an explosion to prevent increased destructive force, while the protective panel needs to provide protection without compromising its explosion venting function. The installation mechanism needs to strike a balance between robustness and ease of removal, ensuring the protective panel is securely installed under normal conditions but can be quickly and safely detached in the event of an explosion. Furthermore, the control of debris from the protective panel is also an essential aspect of the design, as the panel may become flying debris in the event of an explosion, and the design must limit its dispersion distance.

[0041] In view of this, the present application provides an explosion relief device that can secure the protective panel to the body without affecting the explosion relief effect, thereby solving at least part of the above-mentioned technical problems.

[0042] Please refer to Figures 1 and 2. In this embodiment, the explosion relief device includes a body 100, an explosion relief plate 200, a protective panel 300, and a weak member 400. The body 100 has an opening 110. The explosion relief plate 200 is installed on the body 100 and covers the opening 110. The protective panel 300 is disposed on the side of the body 100 with the opening 110 and is disposed opposite to the explosion relief plate 200 at a distance. The protective panel 300 is connected to the body 100 through the weak member 400. The weak member 400 is configured to break when the explosion relief plate 200 is depressurized, so that the protective panel 300 can be detached from the body 100.

[0043] It should be noted that the explosion relief panel 200 is a safety device designed to rapidly release internal pressure in the event of an explosion or sudden pressure increase within an enclosed space, preventing damage to equipment or structures. Its main function is to automatically open when the pressure reaches a predetermined threshold, releasing excessive pressure to protect equipment and the surrounding environment. Explosion relief panels 200 are commonly used in industrial facilities, energy storage systems, chemical plants, grain processing plants, and other locations where explosive gases, dust, or other flammable substances may be present. Common explosion relief panels 200 include an explosion relief panel body, an explosion relief door, and a pressure relief valve, etc., and the technology is relatively mature and will not be described in detail in this embodiment.

[0044] This embodiment, by installing a pressure relief plate 200 on the main body 100 and connecting the protective panel 300 with a weak link 400, can rapidly release pressure when internal pressure suddenly increases, preventing damage to the main body 100 due to excessive pressure, thereby improving overall safety. Under normal operating conditions, the protective panel 300 is securely connected to the main body 100 via the weak link 400, ensuring structural stability and integrity, and not affecting the daily use and maintenance of the equipment. The design of the weak link 400 ensures that it will break when a specific pressure is reached, allowing the protective panel 300 to quickly detach from the main body 100, achieving a highly efficient pressure relief effect and reducing the impact of an explosion on the equipment and the environment. In summary, this pressure relief device design, through structural optimization, achieves the technical effects of safety, stability, and efficient pressure relief, and is suitable for energy storage application scenarios requiring high safety standards.

[0045] In some embodiments, referring to Figures 3 and 4, the weak member 400 includes a main body 410 and a first connecting portion 420. The main body 410 is disposed on the side of the protective panel 300 opposite to the body 100. The main body 410 has a mounting hole 412 for the first connecting portion 420 to pass through and a weak hole 411 surrounding the mounting hole 412, forming a weak region 413 between the mounting hole 412 and the weak hole 411. In the event of depressurization of the explosion relief plate 200, the weak region 413 breaks to allow communication between the mounting hole 412 and the weak hole 411. In the event of depressurization of the explosion relief plate 200, the main body 410 breaks to allow the protective panel 300 to detach from the body 100.

[0046] It should be noted that, referring to Figure 5, the first connecting portion 420 includes a first end 421 and a second end 422 connected together. The first end 421 passes through the main body 410 and the protective panel 300 and connects to the body 100. The second end 422 presses the main body 410 and the protective panel 300 onto the body 100. The shape of the main body 410 can be circular, quadrilateral, elliptical, etc., as long as the orthographic projection of the main body 410 on the body 100 is greater than the orthographic projection of the second end 422 on the body 100. In this embodiment, the specific shape of the main body 410 is not limited. To facilitate the connection between the first connecting portion 420 and the body 100, the body 100 is provided with a mounting groove. After the first end 421 passes through the main body 410 and the protective panel 300 in sequence, it extends into the mounting groove to achieve a tight connection with the body 100. At the same time, the second end 422 presses the protective panel 300 towards the body 100, thereby forming a stable connection between the protective panel 300 and the body 100. When the explosion relief plate 200 depressurizes, the main body 410 breaks, preventing the first connecting part 420 from continuing to fasten the main body 410. At this time, the protective panel 300 loses the fastening effect of the main body 410 and can quickly detach from the body 100. This design ensures that in the event of excessive internal pressure in the body 100, the explosion relief plate 200 can effectively release pressure without being affected by the protective panel 300, thereby protecting the safety of the body 100 and the surrounding environment.

[0047] In some examples, the main body 410 uses a gasket, and the first connecting part 420 uses a bolt. The combination of the gasket, bolt, and nut provides a simple and effective connection, ensuring quick release of the protective panel 300 when needed. The gasket can be made of a fragile material, such as a thin metal sheet or high-strength plastic, which breaks rapidly under excessive pressure. The gasket can be circular, quadrilateral, or elliptical, depending on design requirements, but the key is that its projected area on the body 100 must be larger than that of the bolt. As the main body 410, the gasket provides a vulnerable point that is prone to breakage; when the internal pressure exceeds the design threshold, the gasket will break first, releasing the protective panel 300. The bolt is typically made of high-strength metal to ensure a reliable connection under normal operating conditions. The bolt passes through the gasket and the protective panel 300 and extends into a mounting groove in the body 100. By tightening the bolt, the protective panel 300 is pressed against the body 100, forming a secure connection. The bolt provides both pressing and securing of the protective panel 300. After the gasket breaks, the bolt loses its ability to press against the protective panel 300, allowing the protective panel 300 to quickly detach from the body 100. Under normal operating conditions, the bolt securely fixes the protective panel 300 to the body 100 through the gasket. When the internal pressure of the body 100 becomes too high, the gasket breaks first, causing the bolt to be unable to continue applying pressure to the protective panel 300. After losing its fixation, the protective panel 300 can quickly detach from the body 100, releasing internal pressure and ensuring safety. This design utilizes the fragility of the gasket and the high-strength fixing capacity of the bolt to provide an effective pressure relief mechanism, ensuring rapid response in emergency situations and protecting the equipment and the surrounding environment.

[0048] It should be noted that the weak point 413 is designed to break quickly when the explosion relief plate 200 needs to be depressurized. The weak point 413 can be made of a thinner or lower-strength material, and it will break first when the internal pressure of the main body 100 reaches a certain level. After breakage, the mounting hole 412 connects with the weak point 411, and the second end 422 does not contact the broken main body 410, preventing the main body 410 from continuing to apply pressure to the protective panel 300, allowing the protective panel 300 to quickly detach from the main body 100. In other words, the explosion relief process becomes more controllable and efficient through the weak point 413. The connection between the mounting hole 412 and the weak point 411 prevents the second end 422 from forming a mechanical connection with the broken main body 410 (the second end 422 does not contact the broken main body 410), thus ensuring that the protective panel 300 can detach from the main body 100 in time when the pressure is too high, avoiding potential damage to the main body 100 and the surrounding environment. This structure not only improves the response speed of the explosion relief plate 200, but also enhances the safety and reliability of the overall system.

[0049] In some examples, the main body 410 has a weak hole 411. To ensure that the protective panel 300 can quickly detach from the main body 100 during explosion venting, this weak hole 411 is arranged in an arc shape around the mounting hole 412. The central angle of the arc shape is greater than 180° and less than 360°. This design ensures that the weak area 413 can break in time when the internal pressure of the main body 100 reaches a certain level. By designing the weak hole 411 as an arc shape with a central angle greater than 180°, a clear weak area 413 is structurally formed. This design makes the weak area 413 more likely to break under internal pressure, so that the mounting hole 412 communicates with the weak hole 411, and the second end 422 does not contact the broken main body 410. This feature ensures that the protective panel 300 can quickly detach from the main body 100 when the pressure is too high, providing timely pressure relief.

[0050] In some examples, as shown in Figure 4, the main body 410 has multiple weak holes 411 spaced around the mounting holes 412. Specifically, the multiple weak holes 411 are evenly distributed around the mounting holes 412, and this layout can be symmetrical to ensure uniform stress distribution throughout the structure. The shape of the weak holes 411 can be circular, elliptical, arc-shaped, or other suitable geometry to meet specific design requirements. By setting multiple weak holes 411, stress concentration can be effectively reduced. Stress concentration often leads to material fatigue and fracture, while evenly distributed weak holes 411 help to disperse stress over a larger area, thereby improving the durability and reliability of the structure. The area between the weak holes 411 and the mounting holes 412 is designed as a weak zone 413. The design of multiple weak holes 411 not only contributes to the physical performance of the structure but also enhances its functionality. For example, during the explosion relief process of the explosion relief panel 200, the layout of the weak holes 411 can ensure that the protective panel 300 can quickly detach in the event of excessive pressure, thereby protecting the equipment and the surrounding environment. By rationally designing the number and distribution of the weak holes 411, the expected performance targets can be achieved without significantly increasing manufacturing complexity. This design can typically reduce material costs and processing difficulty.

[0051] In some embodiments, the design optimizes the performance of the explosion relief device through specific distance relationships. Specifically, as shown in Figure 3, the maximum distance between the center of the weak hole 411 and the center of the mounting hole 412 is defined as the first distance L1, and the maximum distance between the second end 422 and the center of the mounting hole 412 is defined as the second distance L2. The design requires that L1 > L2. This distance relationship design helps ensure that the weak area 413 fractures preferentially when the pressure is too high. Since L1 is greater than L2, the weak area 413 between the weak hole 411 and the mounting hole 412 is structurally more susceptible to stress concentration, thus making it more prone to fracture when the pressure increases. This design ensures that during the explosion relief process, the weak area 413 can quickly form an avoidance hole 414, allowing the protective panel 300 to detach from the body 100 in a timely manner. Through this optimization of distance relationships, the protective panel 300 can respond quickly when the pressure is too high, providing higher safety and reliability.

[0052] Furthermore, the second distance L2 must be greater than the radius of the mounting hole 412. This ensures that in the event of excessive pressure or explosion venting, fracture is more likely to occur in the predetermined weak point 413. This design strategy of controlling the fracture location helps ensure the predictability and safety of the explosion venting process. By optimizing the distance relationship, ensuring that the weak point 413 fractures preferentially in the event of excessive pressure allows for the rapid formation of the clearance hole 414. This design enables the protective panel 300 to detach from the body 100 in a timely manner, thereby effectively releasing internal pressure and preventing greater structural damage or safety accidents.

[0053] In some embodiments, referring to Figure 6, the explosion relief device further includes a second connecting portion 500. One end of the second connecting portion 500 is connected to the protective panel 300, and the other end is connected to the body 100. The second connecting portion 500 is folded between the protective panel 300 and the body 100. It should be noted that the introduction of the second connecting portion 500 provides additional support and flexibility for the installation and function of the protective panel 300. The second connecting portion 500 can be made of flexible yet strong materials, such as metal springs, rubber bands, or high-strength fiber ropes. This design allows it to remain compact under normal conditions while being able to unfold quickly when needed. One end of the second connecting portion 500 is fixed to the protective panel 300, and the other end is fixed to the body 100. The connection method can be hinged, bolted, or welded, ensuring a stable connection during normal use. Its length and elasticity are not specifically limited, as long as sufficient cushioning is provided to prevent the panel from flying too far when the protective panel 300 is detached. In other words, in the event of an explosion or a sudden increase in pressure, the second connection 500 can provide a buffer when the protective panel 300 detaches, slowing down the scattering speed of the protective panel 300, thereby controlling the scattering distance of the control panel and reducing potential hazards to the surrounding environment and personnel. Its design ensures that after the weak component 400 breaks, the protective panel 300 can quickly and safely detach from the main body 100.

[0054] In some embodiments, as shown in FIG1, a plurality of weak links 400 are introduced into the design, which are circumferentially spaced around the protective panel 300. The multiple weak links 400 are used to secure the protective panel 300 to the body 100, and are circumferentially spaced around the protective panel 300. This design ensures that the protective panel 300 is securely connected to the body 100 under normal operating conditions. The primary function of the weak links 400 is to provide sufficient connection strength under normal conditions to maintain the stability of the protective panel 300. However, in emergency situations such as explosions or sudden pressure increases, these weak links 400 will preferentially break, allowing the protective panel 300 to quickly detach from the body 100, thereby releasing internal pressure and protecting the equipment and personnel. By circumferentially spaced multiple weak links 400, a uniform distribution of connection strength can be achieved. This layout helps prevent loosening or displacement of the protective panel 300 during normal use, while ensuring that the panel can be released simultaneously at multiple points in emergency situations, avoiding excessive stress on a single connection point. This design strategy not only improves the fixation reliability of the protective panel 300, but also enhances the system's safety and responsiveness under extreme conditions. By precisely designing the number, location, and material properties of the weak points 400, effective detachment in emergency situations can be ensured without affecting normal use.

[0055] In some embodiments, there are multiple second connecting portions 500, which are circumferentially spaced around the protective panel 300. This design helps ensure that the protective panel 300 does not detach too far in an uncontrolled manner when it is ejected. The evenly distributed multiple second connecting portions 500 help control the scattering distance of the control panel, improving the safety and reliability of the system. Even in emergency situations, the presence of multiple connecting portions provides redundancy, ensuring that the detachment process of the protective panel 300 is controllable.

[0056] In some embodiments, as shown in FIG6, the protective panel 300 has a first side 310 and a second side 320 disposed opposite to each other. The first side 310 is mechanically hinged to the body 100 (any hinged structure between the protective panel 300 and the body 100 can be used in this embodiment; no specific limitation is made to the hinge structure here). This allows the protective panel 300 to rotate relative to the body 100 about the first side 310 as a rotation axis, maintaining structural stability under normal conditions. At least one weak member 400 is provided on the second side 320.

[0057] It should be noted that the weak component 400 includes structures such as a main body 410 and a first connecting part 420 (the main body 410 may be made of easily broken components such as gaskets, and the first connecting part 420 may be made of bolts, etc.). The main body 410 has a mounting hole 412 and a weak hole 411 arranged around it, forming a weak area 413 between the two. The first end 421 of the first connecting part 420 passes through the mounting hole 412 of the main body 410 and the protective panel 300 in sequence, and extends into the mounting groove of the body 100 to achieve a fastening connection. Its second end 422 presses the main body 410 and the protective panel 300 onto the body 100, and the outer diameter of the second end 422 is larger than the diameter of the mounting hole 412.

[0058] During the explosion venting process, when the internal pressure of the main body 100 reaches a certain level, the explosion venting plate 200 opens to release pressure. The weak area 413 of the main body 410 of the weak component 400 on the second side 320 will break first, causing the mounting hole 412 to connect with the weak hole 411. The first connecting part 420 will no longer be in contact with the broken main body 410, thus causing the protective panel 300 to lose its fastening force at the second side 320. At this time, the protective panel 300 will rotate and open about the first side 310 as an axis. It will not completely detach from the main body 100, but it can release the excessive pressure inside the main body 100 in time, effectively achieving the purpose of explosion venting and ensuring the safety of the equipment and the surrounding environment.

[0059] In some embodiments, as shown in FIG6, the explosion relief device further includes a support portion 600, which is disposed around the opening 110 and connected to the body 100. The protective panel 300 is connected to the support portion 600, and a third distance L3 exists between the protective panel 300 and the explosion relief plate 200, satisfying 15mm≤L3≤25mm. The spatial interval between the two is precisely constructed by the height and installation position of the support portion 600.

[0060] It should be noted that one end of the support 600 is fixedly connected to the main body 100, while the other end firmly supports the protective panel 300, maintaining a predetermined distance between them. The value of the third distance L3 is not arbitrarily determined, but rather is decided by comprehensively considering the flatness of the protective panel 300 and the amount of deformation that may occur due to impact from foreign objects. On the one hand, the flatness of the protective panel 300 must be taken into account to ensure that it is flat after installation, avoiding the mutual compression and deformation of the protective panel 300 and the explosion relief plate 200 due to insufficient distance. On the other hand, the amount of deformation that may be caused by impact from foreign objects must also be considered to ensure that the protective panel 300 still has sufficient buffer space when subjected to accidental impact, preventing excessive deformation that could hinder the normal pressure relief of the explosion relief plate 200.

[0061] It should be noted that the support 600 has two opposing parts, one of which is connected to the first side 310 and the other is connected to the second side 320. This connection method helps to stably position the protective panel 300 on the side of the main body 100 where the opening 110 is located, ensuring the positional stability of the protective panel 300 in the normal state. It also provides a reliable support foundation for the protective panel 300 to rotate and open around the first side 310 as an axis during explosion venting, ensuring the smooth progress of the explosion venting process.

[0062] In some embodiments, as shown in FIG6, based on further considerations of the safety and reliability of the explosion venting device, the distance between the support portion 600 and the explosion venting plate 200 is specifically set to be greater than the distance between the protective panel 300 and the explosion venting plate 200 in the explosion venting direction of the explosion venting device. Specifically, the distance between the support portion 600 and the explosion venting plate 200 refers to the vertical distance between the end face of the support portion 600 away from the explosion venting plate 200 and the explosion venting plate 200; while the distance between the protective panel 300 and the explosion venting plate 200 is the vertical distance between the end face of the protective panel 300 away from the explosion venting plate 200 and the explosion venting plate 200.

[0063] It should be noted that, from a spatial layout perspective, this distance setting method, with the explosion venting direction as the height direction, ensures that the end face of the support part 600 furthest from the explosion venting plate 200 is higher than the end face of the protective panel 300. During the explosion venting process, when the explosion venting plate 200 opens to release internal pressure, and the protective panel 300 is ejected under pressure impact, the support part 600, with its higher position and surrounding layout, naturally guides and constrains the movement trajectory of the protective panel 300. The guiding effect of the support part 600 on the protective panel 300 effectively prevents the protective panel 300 from shifting or flipping significantly during ejection, thus preventing it from colliding with surrounding equipment and structures due to irregular movement and causing additional damage. Furthermore, it ensures that the protective panel 300 moves quickly and smoothly along the preset explosion venting channel, allowing for efficient release of internal pressure and minimizing the impact of pressure retention on the explosion venting device and the surrounding environment. At the same time, this design can further precisely control the movement direction and speed of the protective panel 300 by optimizing the shape, size and installation angle of the support part 600, so as to achieve refined management of the explosion venting process and significantly improve the overall performance and safety of the explosion venting device.
