Description

Technical Field

[0001] The present application belongs to the technical field of explosion-proof energy storage equipment, and in particular, relates to an explosion relief device and energy storage equipment. Background Art

[0002] During the use of the energy storage cabinet, if there is a rapid rise in pressure in the closed structure, and the structural strength is not enough to withstand the explosion pressure, the entire energy storage cabinet is likely to explode and cause significant losses and casualties. Therefore, it is often necessary to install an explosion relief plate on the energy storage cabinet to release pressure by utilizing its deformation and damage during the explosion, so as to control the occurrence of the explosion or minimize the degree of the explosion. However, when the explosion relief plate is set on the side wall of the energy storage cabinet, when the explosion relief plate is fully opened due to the impact of the explosion, it is easy to release the explosion pressure and flames laterally to the surrounding environment, endangering surrounding buildings, passing vehicles and personnel, etc. Utility Model Content

[0052] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0053] Reference below Figure 1-Figure 10 The explosion relief device provided in the embodiment of the present application is described, and the explosion relief device includes an explosion relief plate 100, a guide device 200 and a limit device 300.

[0054] The explosion venting plate 100 is arranged at the explosion venting opening of the energy storage cabinet side wall 900. The material of the explosion venting plate 100 includes but is not limited to sheet metal, stainless steel, aluminum alloy or titanium alloy. It should be noted that the size and specific position of the explosion venting opening can be designed according to actual needs, and this embodiment does not impose specific restrictions on this. The connection method between the explosion venting plate 100 and the energy storage cabinet side wall 900 includes but is not limited to bolt connection, rivet connection or welding.

[0055] In this embodiment, the explosion venting plate 100 is threadedly connected to the energy storage cabinet side wall 900 on all sides, so as to ensure that the entire explosion venting plate 100 is in close contact with the energy storage cabinet side wall 900 to seal the explosion venting port, thereby ensuring the overall sealing performance of the energy storage cabinet. It should be noted that the size of the explosion venting plate 100 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0056] In this embodiment, the explosion relief plate 100 is located on the right side of the energy storage cabinet 900. For ease of understanding, the front-to-back direction in this embodiment refers to the width direction of the energy storage cabinet, the left-right direction refers to the length direction of the energy storage cabinet, and the up-down direction refers to the height direction of the energy storage cabinet.

[0057] The guide device 200 is installed on the side wall where the explosion relief plate 100 is located, and the guide device 200 and the energy storage cabinet side wall 900 are surrounded to form an escape space with an opening, wherein in the case of an explosion, at least part of the explosion relief plate 100 is separated from the energy storage cabinet side wall 900 to allow the explosive to move along the opening direction. The connection method between the guide device 200 and the energy storage cabinet side wall 900 includes but is not limited to bolt connection, rivet connection or welding.

[0058] Similarly, in this embodiment, the guide device 200 is also installed on the right side of the energy storage cabinet.

[0059] It can be understood that when the pressure inside the energy storage cabinet rises rapidly due to the explosion, the explosion relief plate 100 is pressurized and forced to at least partially separate from the energy storage cabinet, so that the explosion relief port is exposed to release the explosive (pressure and flame) in the energy storage cabinet, and because a refuge space with an opening is formed between the side wall 900 of the energy storage cabinet and the guide device 200, the pressure and flame in the energy storage cabinet can be released from the opening of the preset refuge space, so as to control the splashing direction of the explosive and minimize the damage to the buildings around the energy storage cabinet and passing vehicles and personnel.

[0060] According to the explosion relief device provided in the embodiment of the present application, the guide device 200 and the side wall 900 of the energy storage cabinet are used to enclose a refuge space with an opening, so that when an explosion occurs, the pressure and flame in the energy storage cabinet can only be released from the opening, thereby controlling the direction of the splash of the explosive and avoiding damage to the buildings around the energy storage cabinet and passing vehicles and personnel as much as possible.

[0061] It should be noted that, when the front and back sides of the explosion venting panel 100 are relatively arranged along the front-to-back direction, the opening of the avoidance space may be at least one of the left, right, upward or downward; when the front and back sides of the explosion venting panel 100 are relatively arranged along the left-to-right direction, the opening of the avoidance space may be at least one of the front, rear, upward or downward, and this embodiment does not impose specific restrictions on this.

[0062] In some embodiments, Figures 1 to 10 As shown, the limiting device 300 is installed on the guide device 200 and is located in the avoidance space, and is used to limit the explosion relief plate 100 from being separated from the guide device 200 in the explosion relief situation.

[0063] It is understandable that when an explosion occurs, the explosion venting plate 100 will first detach from the side wall 900 of the energy storage cabinet due to the impact force of the explosion. Due to the existence of the guide device 200, the explosion venting plate 100 after detachment will contact the guide plate 220 of the guide device 200. Since the impact force of the explosion is large, the explosion venting plate 100 will rebound due to a large reaction force after contacting the guide plate 220 of the guide device 200. In this embodiment, the change of the explosion venting direction is achieved by avoiding the opening of the space. The explosion venting plate 100 is limited by the limiting device 300, which can prevent the explosion venting plate 100 from rebounding due to the reaction force and approaching the side wall 900 of the energy storage cabinet again, thereby blocking the explosion venting port and ensuring the explosion venting efficiency as much as possible.

[0064] In some embodiments, Figures 4 to 6 As shown, the guide device 200 includes two side plates 210 and a guide plate 220, the two side plates 210 are arranged opposite to each other, and the two side plates 210 are connected to the energy storage cabinet side wall 900; the two ends of the guide plate 220 are respectively connected to the two side plates 210, wherein the guide plate 220, the two side plates 210 and the energy storage cabinet side wall 900 are surrounded to form an escape space with an opening. The materials of the side plates 210 and the guide plates 220 include but are not limited to sheet metal, stainless steel, aluminum alloy or titanium alloy. The connection method between the side plates 210 and the energy storage cabinet side wall 900 and the connection method between the side plates 210 and the guide plates 220 include but are not limited to bolt connection, rivet connection or welding.

[0065] It is understandable that, since the guide device 200 is installed on the right side wall of the energy storage cabinet, the two side panels 210 are relatively arranged on both sides of the guide plate 220 along the front-to-back direction, that is, the right side wall of the energy storage cabinet, one side panel 210, the guide plate 220 and the other side panel 210 are sequentially connected to form an escape space. It is understandable that before the explosion occurs, one side of the explosion venting plate 100 covers the explosion venting port to ensure the overall sealing of the energy storage cabinet, and the energy storage cabinet is used normally. After the explosion occurs, the explosion venting plate 100 is separated from the side wall 900 of the energy storage cabinet, so that the explosives released from the explosion venting port can fly out from the opening.

[0066] In some implementations, such as Figures 1 to 3 As shown, considering the upward movement of hot air, the opening of the avoidance space is upward, thereby further reducing the impact on the surrounding environment, vehicles and personnel. It should be noted that the size of the upward opening can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0067] In this embodiment, the escape space also has a downward opening, that is, the upper end and the lower end of the guide plate 220 are respectively at a certain distance from the energy storage cabinet side wall 900, so as to further improve the air explosion relief efficiency. Of course, in some embodiments, the lower end of the guide plate 220 may also abut against the energy storage cabinet side wall 900 to improve the stability of the connection between the guide device 200 and the energy storage cabinet side wall 900, and ensure that the explosion relief plate 100 is always located in the escape space after the explosion occurs, so as to avoid the explosion relief plate 100 being separated from the energy storage cabinet side wall 900 as a whole, causing damage to surrounding buildings, passing vehicles and personnel.

[0068] In this embodiment, the side plate 210 and the guide plate 220 are an integrally formed structure to ensure the overall strength of the guide device 200 .

[0069] In some embodiments, Figures 4 to 6 As shown, the guide plate 220 is inclined from top to bottom toward the direction close to the side wall 900 of the energy storage cabinet.

[0070] It can be understood that by setting the guide plate 220 at an angle, on the one hand, it can guide the movement of the explosion venting plate 100 during the explosion venting process, so that the explosion venting plate 100 as a whole can rotate around the lower end of the explosion venting plate 100 as the axis and then approach the inner wall of the guide plate 220, thereby increasing the contact area between the explosion venting plate 100 and the guide plate 220 as much as possible; on the other hand, based on the principle of upward movement of hot air, the cross-sectional area of ​​the avoidance space gradually increases from bottom to top, further accelerating the explosion venting speed.

[0071] In some embodiments, Figures 1 to 10 As shown, the guide plate 220 is provided with first through holes 2201 for pressure relief to further improve the explosion relief efficiency. It should be noted that the number and specific distribution of the first through holes 2201 can be designed according to actual needs, and this embodiment does not impose any specific restrictions on this.

[0072] In some embodiments, Figure 5 and Figure 6 As shown, the guide plate 220 includes at least two guide segments 221 connected in sequence along the horizontal direction, and two adjacent guide segments 221 are arranged at an angle so that the guide plate 220 as a whole protrudes outward.

[0073] It should be noted that “outward” refers to the direction away from the side wall 900 of the energy storage cabinet. In this embodiment, bulging outward means bulging to the right.

[0074] It can be understood that, since the two adjacent guide segments 221 in the front-to-back direction are arranged at an angle so that the guide plate 220 as a whole protrudes in the direction away from the side wall 900 of the energy storage cabinet, when the explosion venting plate 100 approaches the guide plate 220 under the action of pressure, the explosion venting plate 100 can be further deformed, that is, the explosion venting plate 100 gradually bulges outward and deforms until it is snap-fitted with the guide plate 220. It can be understood that the final shape of the explosion venting plate 100 after deformation is consistent with the combined shape of the multiple guide segments 221. Since the explosion venting plate 100 has been deformed, its rebound in the guide device 200 will be restrained. In this way, not only can the deformation of the explosion venting plate 100 be accelerated to release as much explosion pressure as possible, but also a certain limiting effect can be played on the explosion venting plate 100, further avoiding the rebound and closure of the explosion venting plate 100 caused by excessive impact force. It should be noted that the number of the guide segments 221 and the angle between two adjacent guide segments 221 can be designed according to actual needs, and this embodiment does not impose any specific restrictions on this.

[0075] In some embodiments, Figure 5 and Figure 6 As shown, the distance between the two side plates 210 away from one end of the energy storage cabinet side wall 900 is smaller than the distance between the two side plates 210 close to one end of the energy storage cabinet side wall 900, thereby further guiding the movement of the explosion venting plate 100, enhancing the deformation degree of the explosion venting plate 100, and further improving the buffering performance and limiting effect.

[0076] For example, in this embodiment, Figure 5 and Figure 6 As shown, the side plate 210 includes a mounting section 211 and a connecting section 212, the mounting section 211 is connected to the energy storage cabinet side wall 900, and the two sides of the connecting section 212 are respectively connected to the mounting section 211 and the guide plate 220. Specifically, the connecting section 212 can be inclined inward relative to the mounting section 211, that is, the two connecting sections 212 are closer to each other as they are farther away from the side wall 900 of the energy storage cabinet. In this way, the distance between the two side plates 210 away from one end of the energy storage cabinet side wall 900 is smaller than the distance between the two side plates 210 close to one end of the energy storage cabinet side wall 900. Optionally, the distance between the two mounting sections 211 can remain unchanged, while the distance between the two connecting sections 212 can be gradually reduced.

[0077] In some embodiments, the connection strength between the bottom side of the explosion venting plate 100 and the energy storage cabinet side wall 900 is greater than the connection strength between the other three sides of the explosion venting plate 100 and the energy storage cabinet side wall 900 .

[0078] It can be understood that when an explosion occurs, since the connection strength between the bottom side of the explosion venting plate 100 and the side wall 900 of the energy storage cabinet is greater than the connection strength between the other three sides of the explosion venting plate 100 and the side wall 900 of the energy storage cabinet, the bottom side of the explosion venting plate 100 is connected to the side wall 900 of the energy storage cabinet, while the top side, left side and right side of the explosion venting plate 100 are separated from the side wall 900 of the energy storage cabinet, so that the explosion venting plate 100 as a whole can be rotated along the bottom side of the explosion venting plate 100 as the rotation axis by a certain angle until one side of the explosion venting plate 100 abuts against the guide plate 220, thereby ensuring that the pressure and flame of the energy storage cabinet can be released from the upward opening of the avoidance space, and also preventing the explosion venting plate 100 from being separated from the side wall 900 of the energy storage cabinet as a whole, further ensuring the safety of the use of the energy storage cabinet.

[0079] In some embodiments, Figures 1 to 4 , Figure 7 and Figure 8 As shown, the limiting device 300 is arranged on the side plate 210 of the guide device 200, and the limiting device 300 includes at least two stoppers 310, and the stoppers 310 switch between a first position and a second position, wherein when the stoppers 310 are in the first position, the explosion venting plate 100 can be avoided, and when the stoppers 300 are in the second position, they can cooperate with the explosion venting plate 100 to limit the position.

[0080] It can be understood that, in the event of an explosion, the stopper 310 is first in the first position to avoid the explosion venting plate 100, thereby facilitating the explosion venting plate 100 to approach the guide plate 220 until the side of the explosion venting plate 100 away from the side wall 900 of the energy storage cabinet contacts the guide plate 220. Subsequently, when the explosion venting plate 100 rebounds toward the side wall 900 of the energy storage cabinet due to the reaction force, the stopper 310 is in the second position so that when the explosion venting plate 100 rebounds, the outer wall of the stopper 310 abuts against the side of the explosion venting plate close to the side wall 900 of the energy storage cabinet. The stopper 310 and the explosion venting plate 100 are limited and cooperated to force the explosion venting plate 100 to be unable to continue to approach the side wall 900 of the energy storage cabinet, so that the explosion venting plate 100 rotates again in the direction away from the side wall 900 of the energy storage cabinet under the action of gravity until the explosion venting plate 100 abuts against the guide plate 220 again, thereby ensuring that the entire explosion venting plate and the opening are not blocked by the explosion venting plate 100.

[0081] In some embodiments, Figure 3 , Figure 7 and Figure 8As shown, the side plate 210 includes a second through hole 213, the stopper 310 is a stopper plate 311, one side of the stopper plate 311 is connected to one side of the second through hole 213, and the movable side of the stopper plate 311 is folded to the inside of the avoidance space; wherein, in the event of an explosion, the explosion venting plate 100 moves from a position close to the side wall 900 of the energy storage cabinet to the guide plate 220, and when the explosion venting plate 100 passes through the stopper plate 311, the movable side of the stopper plate 311 and the explosion venting plate 100 guide cooperate so that the stopper plate 311 is suitable for moving from the first position to the second position, and when the stopper plate 311 is in the second position, the stopper plate 311 and the explosion venting plate 100 abut. The material of the stopper plate 311 includes but is not limited to stainless steel, aluminum alloy or titanium alloy. It should be noted that the size, shape and specific position of the second through hole 213 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0082] It is understandable that in the event of an explosion, the explosion venting plate 100 rushes through the stop plate 311 and abuts against the guide plate 220 under the action of a strong impact force, and drives the connection between the stop plate 311 and the side plate 210 to deform so that the movable side of the stop plate 311 moves to the second position. At this time, compared with when the stop plate 311 is in the first position, the angle between the stop plate 311 and the inner side surface of the side plate 210 changes. Specifically, when the stop plate 311 is in the first position, the angle between the stop plate 311 and the inner side surface of the side plate 210 is smaller than the angle between the stop plate 311 and the inner side surface of the side plate 210 when the stop plate 311 is in the second position. If the explosion venting plate 100 rebounds, it will stop moving when it rebounds to contact the side of the stop plate 311 away from the side wall 900 of the energy storage cabinet. This is because the rebound force at this time is smaller than the deformation force at the connection between the stop plate 311 and the side plate 210, so the explosion venting plate 100 is forced to be unable to continue to move in the direction close to the side wall 900 of the energy storage cabinet, thereby limiting the explosion venting plate 100.

[0083] In some embodiments, Figure 3 and Figure 7 As shown, in order to ensure the strength of the connection between the stop plate 311 and the side plate 210, the stop plate 311 and the side plate 210 are integrally formed.

[0084] In some embodiments, Figure 8 and Fig. 9As shown, the stopper 310 includes a stopper block 3122 and an elastic member 3123, wherein the stopper block 3122 is installed in the second through hole 213 so that the stopper block 3122 at least partially extends into the inner side of the avoidance space; the elastic member 3123 is arranged between the stopper block 3122 and the guide device 200, wherein, in the event of an explosion, the explosion relief plate 100 moves from a position close to the side wall 900 of the energy storage cabinet to the guide plate 220, and when the explosion relief plate 100 passes through the stopper block 3122, the elastic member 3123 drives the stopper block 3122 to move from the second position to the first position, wherein, when the stopper block 3122 is in the second position, the stopper block abuts against the guide device 200 and the explosion relief plate 100 respectively. The stopper block 3122 is made of stainless steel, aluminum alloy or titanium alloy, etc. The elastic member 3123 includes but is not limited to a spring or a torsion spring.

[0085] It can be understood that when the explosion venting plate 100 moves and approaches the guide plate 220 under the action of the explosion impact force, the stop block 3122 contacts the side of the explosion venting plate 100 away from the side wall 900 of the energy storage cabinet, so that the stop block 3122 moves from the second position to the first position, and drives the elastic member 3123 to deform; when the explosion venting plate 100 abuts against the guide plate 220, the elastic member 3123 has driven the stop block 3122 to move from the first position to the second position under the action of its own resilience; when the explosion venting plate 100 rebounds due to the reaction force, the stop block 3122 abuts against the side of the explosion venting plate 100 close to the side wall 900 of the energy storage cabinet and the guide device 200 at the same time, so that the explosion venting plate 100 is forced to be unable to continue to move in the direction close to the side wall 900 of the energy storage cabinet, thereby achieving the limitation of the explosion venting plate 100.

[0086] In this embodiment, Figure 8 and Fig. 9 As shown, the stopper 310 also includes a fixing seat 3121, the fixing seat 3121 is mounted on the outer wall of the side plate 210, the stopper 3122 is rotatably mounted on the fixing seat 3121 along the vertical axis, and the elastic member 3123 is respectively connected to the fixing seat 3121 and the stopper 3122 to achieve the switching of the stopper 3122 between the first position and the second position. The fixing seat 3121 is made of stainless steel, aluminum alloy or titanium alloy. The connection method between the fixing seat 3121 and the side plate 210 includes but is not limited to bolt connection, rivet connection or snap connection.

[0087] It can be understood that the stop block 3122 is rotatably installed on the fixed seat 3121 through the rotating shaft 3124, and the axis of the rotating shaft 3124 is parallel to the up and down direction. When the explosion venting plate 100 moves under the action of the explosion impact force and approaches the guide plate 220, the explosion venting plate 100 can make the stop block 3122 rotate to the first position in the direction close to the guide plate 220, and drive the elastic member 3123 to deform, so that the explosion venting plate 100 can pass through the area. When the explosion venting plate 100 passes through this area, the elastic member 3123 has driven the stop block 3122 to rotate in the opposite direction to the initial position under the action of its own rebound force. When the explosion venting plate 100 rebounds, the explosion venting plate 100 contacts the stop block 3122, which will cause the stop block 3122 to continue to rotate in the opposite direction to the second position and drive the elastic member 3123 to deform. It can be understood that at this time, the stop block 3122 will abut against the explosion venting plate 100, resulting in the explosion venting plate 100 being unable to pass through this area. In this way, since the stop block 3122 abuts against the second through hole 213 or the inner wall of the fixing seat 3121, the explosion venting plate 100 is forced to be unable to continue to move in the direction close to the side wall 900 of the energy storage cabinet, thereby causing the explosion venting plate 100 to move toward the guide plate 220 again, and the elastic member 3123 also drives the stop block 3122 back to the initial position under the action of its own rebound force, thereby preventing the explosion venting plate 100 from rebounding to close the explosion venting port.

[0088] Optionally, the fixing seat 3121 is in a "X" shape to make the overall structure of the limiting device 300 as compact as possible.

[0089] Of course, in some other embodiments, the stop block 3122 is installed on the fixing seat 3121 by being moved in the horizontal direction, so that the stop block 3122 can be switched between the first position and the second position.

[0090] It can be understood that the stopper block 3122 is slidably mounted on the fixing seat 3121 along the front-back direction through the slider guide rail. When the explosion venting plate 100 moves under the action of the explosion impact force and approaches the guide plate 220, the explosion venting plate 100 causes the stopper block 3122 to move outward from the second position to the first position at the second through hole 213, and drives the elastic member 3123 to deform, so that the explosion venting plate 100 can pass through the area. After the explosion venting plate 100 passes through the area, the elastic member 3123 has driven the stopper block 3122 from the first position back to the second position under the action of its own resilience. When the explosion venting plate 100 rebounds, the stopper block 3122 abuts against the explosion venting plate 100. At the same time, since the stopper block 3122 abuts against the inner wall of the second through hole 213 or the fixing seat 3121, the explosion venting plate 100 is forced to be unable to continue to move in the direction close to the side wall 900 of the energy storage cabinet, so that the explosion venting plate 100 abuts against the guide plate 220 again.

[0091] In some embodiments, Figure 8 and Fig. 9As shown, a side of the stop block 3122 close to the energy storage cabinet side wall 900 has a guide surface for guiding the stop block 3122 when it moves to the first position.

[0092] In this embodiment, the guide surface is inclined from inside to outside in a direction close to the energy storage cabinet side wall 900. It should be noted that the inclination of the guide surface can be designed according to actual needs, and this embodiment does not impose any specific restrictions on this.

[0093] In some embodiments, Fig.10 As shown, the limiting device 300 includes at least one piercing member 320, which is installed on a side of the guide device 200 away from the side wall 900 of the energy storage cabinet and is located in the avoidance space, wherein, in the event of an explosion, the piercing member 320 can pierce the explosion relief plate 100. The material of the piercing member 320 may include but is not limited to stainless steel, aluminum alloy or titanium alloy. The connection method between the piercing member 320 and the guide device 200 includes but is not limited to bolt connection, rivet connection, welding or snap connection, etc.

[0094] It is understandable that when the explosion venting plate 100 is close to the guide plate 220, the piercing member 320 can pierce the side of the explosion venting plate 100 away from the energy storage cabinet side wall 900 or even pierce the entire explosion venting plate 100 under the action of the impact force, which can also play a role in limiting the rebound of the explosion venting plate 100. In this embodiment, at least two piercing members 320 are installed on the guide plate 220. It should be noted that the number and specific parts of the piercing members 320 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0095] It should be noted that when the guide device 200 is Figure 4 As shown, that is, the side of the guide plate 220 away from the energy storage cabinet is a plane, and the limiting device 300 includes but is not limited to at least one of the stop plate 311, the stop block 3122 and the piercing member 320; when the guide device 200 is as shown Figure 5 and Figure 6 As shown, the side of the guide segment 221 away from the energy storage cabinet includes at least two guide segments 221 connected in sequence at an angle, and the limiting device 300 only includes the piercing member 320.

[0096] The embodiment of the present application also provides an energy storage device.

[0097] like Figures 1 to 3 As shown, the energy storage device includes an energy storage cabinet and the above-mentioned explosion relief device, and the explosion relief device is installed on the side wall 900 of the energy storage cabinet.

[0098] According to the energy storage device provided in the embodiment of the present application, a refuge space with an opening is formed by using the guide device 200 and the side wall 900 of the energy storage cabinet in the explosion relief device, so that the pressure and flame in the energy storage cabinet can only be released from the opening when an explosion occurs, thereby achieving precise control of the size and direction of the explosion, and avoiding damage to buildings around the energy storage cabinet and passing vehicles and personnel as much as possible.
