[0095] The core of the present application is to provide an explosion venting device and an energy storage cabinet to solve the problem that the explosion venting function of the explosion venting device is easy to fail.

[0096] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0097] Generally, the explosion venting device mainly vents explosion by breaking the weak point on the metal plate by the explosion shock wave. The explosion venting device has the disadvantages of high manufacturing cost and high use cost. At present, in order to solve the problem of high cost, the explosion venting device more adopts the structure form of explosion venting plate cooperating with explosion venting connecting piece. Specifically, the explosion venting connecting piece is fixed to the explosion venting window of the cabinet body from the outside of the explosion venting plate. The scheme mainly utilizes the explosion impact force received by the explosion venting plate to drive the part of the explosion venting connecting piece located outside the explosion venting plate to deform, so that the explosion venting plate can be separated from the explosion venting connecting piece to realize explosion venting. However, under the structure of the explosion venting device, since the part of the explosion venting connecting piece deformed is exposed to the external environment of the cabinet body, the explosion venting connecting piece is easy to be affected by the external environment and rusted to cause the explosion venting function to fail.

[0098] Therefore, with reference to Figure 1 and Figure 2 in combination with 3- Figure 8 , the embodiment of the present application provides an explosion venting device for being installed to the explosion venting window 10 of the cabinet body 1, so as to timely vent explosion through the explosion venting device when the cabinet body 1 reaches the explosion venting pressure. The explosion venting device specifically comprises an explosion venting plate 2 and an explosion venting connecting piece 3. The explosion venting plate 2 is used in a sealing and cooperating manner to cover the explosion venting window 10 of the cabinet body 1. The explosion venting window 10 is an opening structure designed on the cabinet body 1 to realize pressure relief. The side of the explosion venting plate 2 facing the explosion venting window 10 is provided with a fixed base 21. The fixed base 21 is specifically a component extending from the side of the explosion venting plate 2 facing the explosion venting window 10 to the side of the explosion venting window 10, that is, on the side of the explosion venting plate 2 away from the external environment. The explosion venting connecting piece 3 is arranged in the cabinet 1 and is mainly used to fix the explosion venting plate 2 to the window edge 101 of the explosion venting window 10. Specifically, the explosion venting connecting piece 3 connects the fixed base 21 and the window edge 101 of the explosion venting window 10. The connection mode of the explosion venting connecting piece 3 and the window edge 101 can be direct connection, such as the structure that the explosion venting connecting piece 3 is directly connected to the structure of the window edge 101, or indirect connection, such as the structure that the explosion venting connecting piece 3 is connected to the additional component arranged on the window edge 101, such as Figure 3The fixing member 104 is arranged on the window edge 101, which refers to the opening edge of the explosion venting window 10, and can be understood as a window frame structure. It is worth mentioning that those skilled in the art should understand that the explosion venting connecting member 3 has an explosion venting disengagement capability, that is, when the disengagement force of the explosion venting plate 2 relative to the window edge 101 exceeds the preset disengagement force required for explosion venting, the explosion venting connecting member 3 can disengage the corresponding components connected thereto, thereby achieving the basic function of disengaging the explosion venting plate 2 from the explosion venting window 10 to complete the explosion venting.

[0099] In the actual application process of the explosion venting device provided in the present application, when the explosion venting plate 2 is sealed and matched to the explosion venting window 10, the fixed base 21 is arranged on the side of the explosion venting plate 2 facing the explosion venting window 10, and the explosion venting connecting member 3 is arranged in the cabinet 1, and the fixed base 21 and the window edge 101 of the explosion venting window 10 are connected through the explosion venting connecting member 3, thereby avoiding the problem of failure of the explosion venting function caused by aging and rusting of the explosion venting connecting member 3 due to the influence of the external environment.

[0100] In some specific embodiments, referring to Figure 1 and Figure 2 in combination with 3- Figure 10 As shown, the above-mentioned explosion venting connecting member 3 can have a first connecting end 31 and a second connecting end 32, the first connecting end 31 is used for direct connection (such as the connection mode shown in Figures 4-6 ) or indirect connection (such as the connection mode shown in Figure 3 ), and the first connecting end 31 can be configured as a deformable connecting end 30, and the second connecting end 32 is used for fixed base 21 connection, and the connection mode can be detachable connection, such as threaded connection and the like, or can be designed as an integral fixed connection, such as welding and the like. Among them, the detachable connection mode is more convenient for repeated use, which helps to reduce the use cost. In addition, the fixed base 21 can be designed as an integral structure, that is, the second connecting end 32 of at least two explosion venting connecting members 3 is connected to one fixed base 21, or the second connecting end 32 of each explosion venting connecting member 3 corresponds to one fixed base 21, at which time the fixed base 21 can be designed as a support column structure, such as a threaded inner hole arranged on the support column when threaded connection is adopted.

[0101] Theoretically, at least one of the first connecting end 31 and the second connecting end 32 is configured as a deformable connecting end 30, i.e. the explosion venting connecting piece 3 has the function of explosion venting disengagement, i.e. the first connecting end 31 is configured as a deformable connecting end 30, or the second connecting end 32 is configured as a deformable connecting end 30, or both the first connecting end 31 and the second connecting end 32 are configured as deformable connecting ends 30, in the case that the disengagement force of the explosion venting plate 2 relative to the window edge 101 exceeds the preset disengagement force required for explosion venting, the deformable connecting end 30 deforms and disengages from the corresponding part to which it is connected.

[0102] It should be noted that only the case where the first connecting end 31 is configured as a deformable connecting end 30 and the second connecting end 32 is configured as a fixed connecting end is shown in the drawings of the present application. The cases where the second connecting end 32 is configured as a deformable connecting end 30 and the first connecting end 31 is configured as a fixed connecting end, and the cases where both the first connecting end 31 and the second connecting end 32 are configured as deformable connecting ends 30 are similar to the former, and even without drawings, it will not affect the understanding of the scheme itself by those skilled in the art, for example, when the second connecting end 32 is configured as a deformable connecting end 30, the corresponding fixed base 21 can be designed as a T-shaped sliding groove structure, the deformable connecting end 30 can be installed on this side by sliding into the T-shaped sliding groove, and the first connecting end 31 is fixed to the window edge 101 by tightening. Among them, referring to Figures 3-10 , the arrangement mode in which the first connecting end 31 is configured as a deformable connecting end 30 and the second connecting end 32 is configured as a fixed connecting end is more convenient for disassembly, maintenance and replacement.

[0103] In further embodiments, referring to Figures 3-6 , the side of the window edge 101 facing the explosion venting plate 2 has a first stepped surface 4, and the side of the explosion venting plate 2 facing the explosion venting window 10 is sealed and matched with the first stepped surface 4 through a sealing assembly 5. By designing the window edge 101 in the form of a stepped surface, on the one hand, it can be more convenient for positioning and installation during assembly between the explosion venting plate 2 and the window edge 101, and on the other hand, it can make the cooperation between the explosion venting plate 2 and the window edge 101 more stable and reliable, and more easily achieve sealing, for example, multiple sealing structures can be designed in the stepped surface 4. Among them, the specific form of the sealing assembly 5 can be a conventional sealing structure form such as foamed silicone, epdm rubber strip, etc., or can be a side clamping type sealing rubber strip as shown in Figure 11 , which has the characteristics of better resilience and higher reliability, and the specific selection and use can be made according to the specific structure form of the window edge 101, which is not limited more specifically here.

[0104] In further embodiments, referring to Figures 3-6As shown, the sealing assembly 5 can specifically include a first sealing member 51 and a second sealing member 52, the first stepped surface 4 includes a first step surface 41 and a second step surface 42 arranged in a stepped manner towards the window center of the explosion vent 10, the first sealing member 51 is arranged on the first step surface 41, and the second sealing member 52 is arranged on the second step surface 42. By designing the sealing assembly 5 in the form of the first sealing member 51 and the second sealing member 52, and cooperating with the two step surfaces respectively, the stepped double sealing can be realized, and the sealing function of the cabinet body 1 is ensured.

[0105] In some specific embodiments, with reference to Figure 3 As shown, the first stepped surface 4 can be specifically configured as a stepped surface formed by folding the window edge 101 towards the first direction and then bending it away from the window center of the explosion vent 10, that is, the first stepped surface 4 is arranged on the bent portion 1012 of the window edge 101, the folded portion 1011 of the window edge 101 is arranged near the window center of the explosion vent 10 and provided with a fixing member 104, and the first connecting end 31 is connected to the fixing member 104, that is, the first connecting end 31 is indirectly connected to the window edge 101; the second stepped surface is arranged on the side of the explosion vent plate 2 facing the explosion vent 10, and the second stepped surface has a third step surface and a fourth step surface, wherein the third step surface is matched with the first step surface 41, and the fourth step surface is matched with the second step surface 42, the first sealing member 51 is arranged between the first step surface 41 and the third step surface, and the second sealing member 52 is arranged between the second step surface 42 and the fourth step surface; the first direction is specifically configured as the direction of the explosion vent 10 facing the explosion vent plate 2. By designing in this structure, the structure processing of the window edge 101 of the explosion vent 10 of the cabinet body 1 is simpler, and the structure is stable and reliable. In addition, by designing the fixing member 104 to be connected with the first connecting end 31, it is more convenient to replace and maintain subsequently, and the problem that the entire cabinet 1 cannot be used after the connected part of the first connecting end 31 is damaged is avoided.

[0106] In some specific embodiments, with reference to Figure 4As shown, the first stepped surface 4 can also be configured as a stepped surface formed by folding the window edge 101 towards the window center side of the venting window 10 after folding towards the first direction, at this time the window edge 101 has a folded part 1011 and a bent part 1012, and the specific processing method can be but not limited to stamping forming. The second stepped surface is arranged on the side of the venting panel 2 facing the venting window 10, the second stepped surface has a third stepped surface and a fourth stepped surface, the third stepped surface is matched with the first stepped surface, the first sealing element 51 is arranged between the third stepped surface and the first stepped surface 41, the fourth stepped surface is arranged opposite to the second stepped surface 42, the fixed base 21 is arranged on the fourth stepped surface, the second sealing element 52 is arranged between the fixed base 21 and the second stepped surface 42, and the first connecting end 31 is connected to the side of the bent part 1012 of the window edge 101 away from the second stepped surface 42; wherein the first direction is configured as the direction of the venting window 10 facing the venting panel 2. By designing the above structure, the production and processing of the cabinet body 1 are more convenient, and at the same time, since the fixed base 21 is designed on the fourth stepped surface of the second stepped surface, it can fix the second sealing element 52 arranged on the second stepped surface 42 to some extent, which is more convenient for the installation of the sealing element.

[0107] Referring to Figure 5 As shown, the edge of the window edge 101 is folded towards the first direction and bent towards the window center side of the venting window 10 to form a ridge structure 103, the ridge structure 103 includes a ridge top 103a and inner edge ridges 103b and outer edge ridges 103c on both sides of the ridge top 103a, wherein the inner edge ridges 103b are arranged close to the window center side of the venting window 10, the first stepped surface 41 is formed on the outer edge ridges 103c, and the second stepped surface 42 is formed on the ridge top 103a; the second stepped surface is arranged on the side of the venting panel 2 facing the venting window 10, the second stepped surface has a third stepped surface and a fourth stepped surface, the third stepped surface is matched with the first stepped surface, the first sealing element 51 is arranged between the third stepped surface and the first stepped surface 41, the fourth stepped surface is arranged opposite to the second stepped surface 42, the second sealing element 52 is arranged between the fourth stepped surface and the second stepped surface 42, the fixed base 21 is arranged on the fourth stepped surface and arranged opposite to the inner edge ridges 103b, and the first connecting end 31 is connected to the inner edge ridges 103b; wherein the first direction is configured as the direction of the venting window 10 facing the venting panel 2. By designing this structure, not only the structural strength of the window edge can be enhanced, but also no additional fixing element needs to be designed outside the window 101, only the structure matched with the first connecting end 31 needs to be designed on the inner edge ridges 103b.

[0108] In some specific embodiments, referring to Figure 6As shown, the first step surface 4 can be specifically configured as a step surface formed by folding the window edge 101 towards the center side of the window of the explosion vent 10 after folding towards the second direction, at which time the window edge 101 has a folded portion 1011 and a bent portion 1012, the first sealing member 51 is arranged between the first step surface 41 and the edge of the explosion vent plate 2, the fixed base 21 is arranged opposite to the second step surface 42, the second sealing member 52 is arranged between the fixed base 21 and the second step surface 42, and the first connecting end 31 is connected to the side of the bent portion 1012 of the window edge 101 away from the second step surface 42; wherein the second direction is configured as the direction of the explosion vent plate 2 towards the explosion vent 10.

By rotating the rod portion of the bolt 3a into the threads of the fixed base 21, the head of the bolt 3a and the explosion vent gasket 3b can pull the explosion vent plate 2 towards the explosion vent 10, so that the explosion vent plate 2 can be more tightly covered on the explosion vent 10. After the explosion vent gasket 3b is forced to deform, the head of the bolt 3a can be separated from the connecting hole 102, so that the fastening force between the explosion vent plate 2 and the window edge 101 disappears, realizing the explosion vent function. By designing the explosion vent connecting piece 3 as an explosion vent bolt structure, the structure is simpler, and the production and large-scale production are facilitated.

[0110] It should be noted that the specific structure of the explosion vent gasket 3b can be selected and designed according to actual needs, such as Figure 12a As shown, the explosion vent gasket 3b is designed as a common circular gasket. When the explosion vent gasket 3b is designed as a circular gasket, a weak structure 3c can also be arranged on the circular gasket, which can be specifically designed as at least one row of radially arranged holes arranged on the circular gasket, and when there are multiple rows of holes, the multiple rows of holes are distributed in a circumferential direction at equal intervals, such as Figure 12b As shown, the structure of three rows of holes; the weak structure 3c can also be designed as Figure 12cThe structure shown in the figure is a circular gasket with holes distributed in the circumference. In addition, referring to Figure 12d As shown, the explosion venting gasket 3b can also be designed as a structure of a flat circular gasket, which is easier to fall off on the short axis side of the flat circle. Referring to Figure 12e As shown, the explosion venting gasket 3b can also be designed as a structure of a double circular gasket, which has two gasket perforations respectively located at the center positions of the two circles of the double circular gasket. In this structure of the explosion venting gasket, the corresponding connecting hole 102 is a waist-shaped hole, which can install two bolts at a time and is easier to deform, and is suitable for the case where the explosion venting pressure is relatively small. In actual application, the structure of the explosion venting gasket 3b can be selected according to actual needs, and no more specific limitations are made here.

[0111] Of course, it can be understood that in addition to being designed as an explosion venting bolt, the explosion venting connecting piece 3 can also be designed as other structures, such as a connecting stud connected to the fixed base 21 and limited by a limiting pin inserted into the connecting hole 102. The limiting pin can be forced to deform, so that the connecting stud can be separated from the connecting hole 102 to realize the explosion venting function. For example, the deformable connecting end 30 can be designed as a rubber limiting piece or other easily deformable structure. In the explosion venting working condition, the explosion venting connecting piece 3 can also be forced to deform to release the connection state to realize the explosion venting function. In actual application, the configuration can be selected according to actual needs, and no more specific limitations are made here.

[0112] In some specific embodiments, referring to Figure 2 , Figure 13 and Figure 14 The number of the above-mentioned explosion venting connecting pieces 3 can be multiple, and arranged at intervals along the circumference of the window edge 101, such as uniformly arranged at equal intervals. The specific number of the explosion venting connecting pieces 3 can be selected according to actual needs. Of course, it can be understood that the number of the above-mentioned explosion venting connecting pieces 3 can also be single, as long as it can realize explosion venting connection.

[0113] It should be noted that, referring to Figure 14 When the number of the explosion venting connecting pieces 3 is multiple, the deformation separation force of any two explosion venting connecting pieces 3 can be designed to be the same, that is, the specifications of the explosion venting connecting pieces 3 are the same. It can also be that the deformation separation force of the explosion venting connecting piece 3 connected to the first strength position 2a of the explosion venting plate 2 is smaller than the deformation separation force of the explosion venting connecting piece 3 connected to the second strength position 2b of the explosion venting plate 2, wherein the anti-deformation strength corresponding to the first strength position 2a of the explosion venting plate 2 is smaller than the anti-deformation strength corresponding to the second strength position 2b of the explosion venting plate 2, such as referring to Figure 14The anti-deformation strength of the positions corresponding to the four corners of the explosion venting plate 2 is lower than that of other positions of the explosion venting plate 2. By designing the explosion venting connectors 3 at the positions prone to deformation, i.e., the weak positions, to have a relatively low shape deformation force, the weak positions can preferentially deform to vent the explosion, where the preferential deformation refers to the weak positions preferentially generating a disengagement gap. The weak positions are mainly used for a working condition in which the pressure inside the cabinet 1 is relatively small. When the internal pressure of the cabinet 1 is relatively large, the explosion venting connectors 3 corresponding to the first strength position 2a and the explosion venting connectors 3 corresponding to the second strength position 2b will both disengage from the shape. This structure is mainly suitable for a working condition in which the pressure inside the cabinet 1 is relatively large, and can achieve stepped explosion venting. By designing the explosion venting connectors 3 in this structure, the replacement frequency of the explosion venting plate can be effectively reduced according to different explosion venting scenes, the use cost is greatly reduced, and the safety performance of the energy storage box is improved.

[0114] In addition, it should be noted that the explosion venting plate 2 can be designed in a rectangular structure or a circular structure. In the circular structure, the weak positions of the explosion venting plate 2 can be achieved by thinning or other methods. In actual application, the design can be selected according to actual needs, and no more specific limitations are made here.

[0115] In some specific embodiments, referring to Figures 1-4 The side of the explosion venting plate 2 facing the explosion venting window 10 can also be provided with a heat preservation structure 6, which can include a heat preservation shell 61 and a heat preservation material 62. The heat preservation shell 61 and the explosion venting plate 2 form a heat preservation cavity, and the heat preservation material 62 is filled in the heat preservation cavity. By designing the heat preservation structure 6, the heat preservation performance of the cabinet 1 can be further improved.

[0116] In some specific embodiments, the explosion venting device can also include an anti-falling assembly 7 connected between the explosion venting plate 2 and the explosion venting window 10 to prevent the explosion venting plate 2 from falling off when the explosion venting plate 2 is disengaged from the explosion venting window 10. Thus, the safety hazard caused by the explosion venting plate 2 flying out can be avoided.

[0117] In further embodiments, referring to Figures 3-10 The anti-falling assembly 7 can include at least one of a hinge 71, an anti-falling cable 72, and a telescopic pull rod. The hinge 71 is used to hinge one side edge of the explosion venting plate 2 to one side window edge 101 of the explosion venting window 10. One end of the anti-falling cable 72 is connected to the explosion venting window 10, and the other end is connected to the side of the explosion venting plate 2 facing the explosion venting window 10. One end of the telescopic pull rod is connected to the explosion venting window 10, and the other end is connected to the side of the explosion venting plate 2 facing the explosion venting window 10. For example, referring to Figs. 9 and Figure 10The anti-falling assembly 7 comprises a hinge 71 and an anti-falling cable 72, wherein the hinge 71 is used to hinge one side edge of the explosion venting plate 2 to one side window edge 101 of the explosion venting window 10; one end of the anti-falling cable 72 is connected to the explosion venting window 10, and the other end is connected to one side of the explosion venting plate 2 facing the explosion venting window 10, and the connection position of the anti-falling cable 72 on the explosion venting plate 2 is away from the hinge position of the explosion venting plate 2. In this way, the anti-falling effect of the explosion venting plate 2 is better.

[0118] Referring to FIGS. 15, 16 and 17, in combination with FIGS. 1-14, Figure 1 and Figure 2 It is to be understood that the explosion venting device can be installed on the top wall 11 or any side wall 12 of the cabinet 1.

Since the explosion venting device has the above-mentioned technical effects, the energy storage cabinet provided with the explosion venting device should also have corresponding technical effects, which will not be described here again. It is worth mentioning that, compared with the explosion venting device arranged on the top wall 11, the opening of the explosion venting plate 2 of the explosion venting device arranged on the side wall 12 (such as the door plate) does not need to consider the gravity of the explosion venting plate 2 or the presence of accumulated snow, and the timeliness of the opening of the explosion venting plate 2 is better.
