Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0035] In the description of this application, it should be understood that the terms "upper," "lower," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, "multiple" means two or more, and "at least one" can refer to one, two, or more, unless otherwise explicitly specified. The terms "first," "second," etc., are only for the convenience of description and are used to name parts or embodiments by number, and do not imply any order of importance between the parts or embodiments.

[0036] It should also be noted that in the accompanying drawings of this application, an arrow marked X is used to indicate the explosion venting direction X. The introduction of the explosion venting direction X in the description of this application is to more clearly define the structure and relative positional relationships of the components in the explosion venting device. In actual implementation, the explosion venting direction X is generally the vertical direction, or the height direction.

[0037] As an introduction to this application embodiment, the explosion venting device, as one of the key safety protection devices, has the core function of releasing pressure and gas in an orderly manner through preset weak points or special devices, such as pressure relief valves or explosion venting plates 11, when the pressure in a confined space reaches a potentially dangerous level, thereby avoiding serious accidents such as structural damage, explosion shock waves, and the release of harmful chemicals. However, during the explosion venting process, the explosion venting plate 11 is prone to malfunction under significant force. For example, when the energy storage container 1 faces thermal runaway of the internal battery cells, there is a problem of flammable gas accumulation and a sharp increase in internal pressure, which may trigger an explosion risk. Under significant force, the explosion venting plate 11 may fly off. Currently, explosion venting plates 11 on the market are generally installed on the top of the energy storage container 1, with no obstructions directly above them. If the explosion venting plate 11 is installed inside the container and there are obstructions on top, it may prevent the explosion venting plate 11 from fully opening, thus affecting the complete release of pressure and increasing the potential risk of explosion.

[0038] In view of the above, this application provides an explosion relief device, which aims to solve at least one of the above-mentioned technical problems.

[0039] Please refer to Figure 1. An embodiment of this application discloses a deflation device, including a deflation assembly 10 and a shielding assembly 20. The deflation assembly 10 is disposed on a mounting surface 100 having a deflation port 101. The deflation assembly 10 includes a deflation plate 11, which covers the deflation port 101. The deflation plate 11 has a deflation direction X. At least a portion of the shielding assembly 20 is spaced apart from the deflation plate 11 along the deflation direction X to shield the deflation plate 11. It should be understood that when the pressure in the confined space reaches the detonation pressure of the deflation plate 11, the deflation plate 11 can move or rotate relative to the mounting surface 100 to open the deflation port 101, thereby releasing the internal pressure of the device and preventing the deflation plate 11 from flying off due to excessive internal pressure, which could then affect the external environment. When the explosion relief plate 11 is in operation, the shielding component 20 can limit the range of motion of the explosion relief plate 11 to block the explosion relief plate 11 from moving during the explosion relief action, effectively solving the problem of traditional explosion relief plates 11 being easily blown away. At the same time, it can also shield the contents flying out of the explosion relief port 101 to reduce the impact on the external environment and surrounding personnel.

[0040] It is important to understand that the shielding component 20 can employ an elastic mesh structure. This elastic mesh is woven from aramid fibers, possessing high strength and toughness. The elastic mesh can buffer and restrict the movement of the explosion relief plate 11, preventing it from collapsing. Simultaneously, the mesh can intercept contents ejected from the explosion relief port 101. The mesh size can be designed according to actual needs, effectively blocking larger objects while allowing some gas to escape smoothly. After the explosion is vented, the elastic mesh can recover its shape due to its elasticity, facilitating subsequent inspection and maintenance.

[0041] It is also important to understand that the shielding component 20 can adopt a magnetic buffer structure. During the explosion venting action, the shielding component 20 and the explosion venting plate 11 may not be in contact, that is, the principle of like poles repelling is used to provide resistance to the opening of the explosion venting plate 11. A magnetic buffer strip is set in the direction of movement of the explosion venting plate 11. The magnetic buffer strip is made of a composite of highly magnetic material and buffer rubber. When the explosion venting plate 11 moves to a certain position, it comes into contact with the magnetic buffer strip. Through the magnetic force and the buffering effect of the rubber, the speed of the explosion venting plate 11 is reduced.

[0042] Referring to Figure 2, in some embodiments, the shielding assembly 20 includes a shielding plate 21. In the explosion venting direction X, the shielding plate 21 is spaced apart from the explosion venting plate 11. During the explosion venting action, the explosion venting plate 11 can abut against the shielding plate 21. It should be understood that the explosion venting action refers to the explosion venting plate 11 detaching from the mounting surface under impact and moving away from the mounting surface. When the explosion venting plate 11 detaches from the mounting surface 100, the shielding plate 21 provides abutment to prevent the explosion venting plate 11 from flying off, limiting the movement stroke of the explosion venting plate 11 and reducing the hazard. When the explosion venting plate 11 rotates relative to the mounting surface 100, the end of the explosion venting plate 11 away from the mounting surface 100 can abut against the shielding plate 21, thereby limiting the movement path of the explosion venting plate 11 without affecting its normal operation, preventing the explosion venting plate 11 from detaching from the mounting surface 100 due to excessive impact during the explosion venting process, and reducing the threat of the explosion venting plate 11 flying off to surrounding personnel or equipment. It is also important to understand that the distance between the rotating end of the explosion relief plate 11 and the end of the explosion relief plate 11 away from the mounting surface 100 needs to be greater than the distance between the baffle plate 21 and the explosion relief plate 11. This is to ensure that the explosion relief plate 11 can abut against the baffle plate 21 during normal opening, so as to disperse the impact force received by the explosion relief plate 11, ensure the reliability and service life of the explosion relief plate 11, and make it move along a predetermined trajectory during the explosion relief process, thereby avoiding disorderly scattering.

[0043] Please refer to Figures 3 and 4. In some embodiments, the explosion venting device further includes a connecting assembly 30. The connecting assembly 30 includes a first bracket 31 and a first connector 32. The first bracket 31 connects to the shielding plate 21 and supports the shielding plate 21, which is spaced apart from the explosion venting plate 11. The first connector 32 connects the shielding plate 21 and the first bracket 31 respectively. The first connector 32 has a weak point 320. When the explosion venting plate 11 and the shielding plate 21 abut against each other, the first connector 32 breaks at the weak point 320, and the shielding plate 21 separates from the first bracket 31. It should be understood that by setting the connecting assembly 30, the shielding plate 21 and the explosion venting plate 11 are spaced apart, and the supporting plate is fixed. When the explosion relief plate 11 abuts against the shielding plate 21, the impact force on the explosion relief plate 11 will be transmitted to the shielding plate 21. Force transmission occurs between the shielding plate 21 and the connecting component 30, which causes the first connecting member 32 to break at the weak part 320, thereby realizing the separation of the shielding plate 21 from the first support 31. The above design can effectively disperse and absorb the impact force, avoid damage to the device due to excessive force or cause secondary danger, and significantly improve the overall safety.

[0044] It is also important to understand that the design of the weak point 320 of the first connector 32 ensures fracture under predetermined conditions (such as high pressure during explosion venting), avoiding structural damage under unexpected circumstances. Through the fracture design of the connector, the enormous impact force generated during explosion venting can be effectively absorbed and dispersed, reducing the impact on other components and thus optimizing energy management throughout the explosion venting process. After the baffle 21 detaches from the first support 31, it can be easily replaced or repaired, not only reducing maintenance costs but also improving the maintainability and flexibility of the explosion venting device.

[0045] Referring to Figure 5, in some embodiments, the baffle plate 21 has an assembly hole 210; the first connecting member 32 includes a screw 321 and a venting gasket 322. The screw 321 passes through the venting gasket 322 and the assembly hole 210, and is connected to the first bracket 31. The baffle plate 21 is sandwiched between the first bracket 31 and the venting gasket 322; the weak part 320 is provided on the venting gasket 322, and the orthographic projection of the screw 321 on the baffle plate 21 is located within the assembly hole 210. It should be understood that the first connecting member 32, composed of the screw 321 and the venting gasket 322, fixes the baffle plate 21 and the first bracket 31. At the same time, the baffle plate 21 is sandwiched between the first bracket 31 and the venting gasket 322, so that during the explosion venting process, the force can be evenly distributed on the venting gasket 322, thereby reducing local stress concentration and the risk of potential structural damage. The weak point 320 is located on the explosion venting gasket 322. When the explosion venting pressure reaches a predetermined value, the weak point 320 of the explosion venting gasket 322 breaks first, allowing the baffle plate 21 to disengage smoothly from the first bracket 31. This design not only ensures the safety of the explosion venting process but also prevents secondary damage caused by excessive strength of the connecting parts, significantly improving the stability and reliability of the explosion venting device during the explosion venting process. Simultaneously, the replaceable explosion venting gasket 322 design extends the service life of the explosion venting device and reduces maintenance costs.

[0046] Specifically, the weak point 320 in this application can be manifested as a thinned area on the explosion vent gasket 322. In addition, the weak point 320 can also be manifested as a specific area on the explosion vent gasket 322 where the force transmission path is relatively narrow. For example, multiple through openings are designed on the explosion vent gasket 322, and the area between adjacent openings constitutes a weak area.

[0047] Please refer to Figures 1, 2, and 3. In some embodiments, the connecting assembly 30 further includes a second bracket 33. The second bracket 33 connects to and supports the shielding plate 21, and is located on the side of the shielding plate 21 away from the first bracket 31. Multiple first connectors 32 are provided, with at least one first connector 32 connecting the shielding plate 21 and the second bracket 33 respectively. When the explosion relief plate 11 abuts against the shielding plate 21, the shielding plate 21 can detach from the second bracket 33. It should be understood that by providing the second bracket 33, and positioning it on the side of the shielding plate 21 away from the first bracket 31, additional support is provided for the shielding plate 21, ensuring its stability before explosion relief and maintaining the overall stability of the device. Secondly, by connecting the baffle plate 21 and the second bracket 33 through at least one first connector 32, the baffle plate 21 can detach from the second bracket 33 when the explosion relief plate 11 abuts against the baffle plate 21, ensuring that the explosion relief plate 11 opens smoothly under high pressure and avoiding incomplete or delayed pressure relief due to structural jamming. Furthermore, this ensures that the load on the baffle plate 21 is evenly distributed when the explosion relief plate 11 abuts against the baffle plate 21, reducing local stress concentration, improving the stability of the baffle plate 21, making the opening process of the explosion relief plate 11 more stable, and reducing the risk of the baffle plate 21 collapsing.

[0048] It is also important to understand that the shield 21 is connected to the first bracket 31 and the second bracket 33 by the first connector 32, which makes the shield 21 easy to install and remove, and reduces maintenance costs and time.

[0049] Referring to Figures 1 and 2, in some embodiments, the explosion relief device further includes a traction rope 40, which is connected to the shielding plate 21. It should be understood that the traction rope 40 can be connected to a fixed object outside the explosion relief device, or it can be connected to the first support 31 or the second support 33. The traction rope 40 restricts the movement path of the shielding plate 21, preventing it from flying off after being impacted by the explosion relief plate 11, thus reducing the threat to the surrounding environment and personnel.

[0050] Referring to Figure 6, in some embodiments, the explosion relief plate 11 includes a first sidewall 111 and a plurality of second sidewalls 112, which are arranged circumferentially. The first sidewall 111 is rotatably connected to the mounting surface 100. The explosion relief assembly 10 also includes a weak member 113, and the second sidewalls 112 are connected to the mounting surface 100 through the weak member 113. It should be understood that the first sidewall 111 of the explosion relief plate 11 is rotatably connected to the mounting surface 100. By setting a plurality of weak members 113 to connect the second sidewalls 112 to the mounting surface 100, during the explosion relief process, the weak member 113 breaks, causing the second sidewalls 112 of the explosion relief plate 11 to detach from the mounting surface 100. The explosion relief plate 11 then rotates around the first sidewall 111 relative to the mounting surface 100, improving the controllability and safety of the explosion relief process and avoiding the fragmentation and secondary injuries caused by traditional explosive explosion relief. The weak component 113 can break under a preset pressure, thereby causing the second sidewall 112 to move or fall off. This controllable failure mechanism ensures the safety and efficiency of the pressure relief process.

[0051] It should be understood that by providing weak elements 113 on each of the second sidewalls 112 of the explosion relief plate 11, and by arranging the weak elements 113 evenly in the circumferential direction, a uniform pressure relief area is formed, making the explosion relief process more balanced and stable.

[0052] Referring to Figure 6, in some embodiments, the explosion relief plate 11 and the weak member 113 are integrally formed. It should be understood that the weak member 113 can be a thin-walled structure protruding from the explosion relief plate 11, and the number of weak members 113 is multiple and they are evenly spaced along the extension direction of the second sidewall 112.

[0053] Please refer to Figure 2. This application also discloses an energy storage container 1. The energy storage container 1 has a mounting surface 100, and an explosion vent 101 is provided on the mounting surface 100. The energy storage container 1 includes the explosion venting device described in the above embodiments. The energy storage container 1 disclosed in this application includes the explosion venting device as described in the above embodiments, and therefore can possess all the technical features and effects of the aforementioned explosion venting device, which will not be repeated here.

[0054] Referring to Figure 2, in some embodiments, the energy storage container 1 includes a first container 102 and a second container 103. An air cooler 2 is mounted on the first container 102. The air cooler 2 and the second container 103 are located on the same side of the first container 102 and spaced apart from each other. A mounting surface 100 is located on the first container 102, and a vent 101 is located between the air cooler 2 and the second container 103. The venting device also includes a traction rope 40, which connects the baffle plate 21 to the second container 103. It should be understood that placing the vent 101 between the air cooler 2 and the second container 103 effectively prevents the vented gas from directly impacting critical equipment or personnel, improving overall safety. Simultaneously, the air cooler 2 and the second container 103 being on the same side and spaced apart from each other helps optimize airflow and improve heat dissipation efficiency.

[0055] It is also important to understand that the explosion relief device is located between the air cooler 2 and the second housing 103, which reduces the space occupied on the energy storage container 1 and makes its structural layout compact.

[0056] In some embodiments, the first bracket 31 can be disposed on the outer casing of the air cooler 2, and the second bracket 33 can be disposed on the second housing 103, as shown in FIG2. Furthermore, in other embodiments, the first bracket 31 and the second bracket 33 can be disposed on other fixed structures, and the specific installation positions can be adaptively selected.

[0057] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
