Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage cabinets, and in particular relates to an explosion relief device for an energy storage cabinet. Background Art

[0002] With the development and application of clean energy, energy storage systems are increasingly used in power systems. As an important component of the energy storage system, energy storage cabinets play a key role in ensuring energy storage and release. However, since dangerous situations such as overheating, overpressure or gas leakage may occur inside the energy storage cabinet, an effective safety protection measure is needed to avoid potential safety accidents. At present, common energy storage cabinets on the market mainly rely on passive explosion relief solutions. When the flammable gas generated by thermal runaway inside the energy storage cabinet gathers and generates heat, causing the pressure to rise to the explosion condition, the explosion relief device passively pops open to release the explosion pressure. This solution has low controllability. When the preload force of the explosion relief device is greater than the explosion relief pressure, the explosion relief device may not be able to pop open in time; when the preload force of the explosion relief device is less than the explosion relief pressure, it may cause premature explosion relief. In addition, the time when the explosion relief device pops open is uncontrollable, and it is impossible to warn the surrounding area in advance, which poses certain safety risks. Utility Model Content

[0003] The utility model aims to solve the above problems in the prior art and to provide an explosion relief device for an energy storage cabinet which can actively vent explosions and has high controllability and safety.

[0004] The purpose of the utility model can be achieved through the following technical solutions, an explosion relief device for an energy storage cabinet, comprising:

[0005] A cabinet door, wherein the cabinet door is provided with an opening for releasing pressure during explosion;

[0006] An explosion relief structure, the explosion relief structure comprising an explosion relief plate rotatably arranged on the cabinet door and blocking the opening;

[0007] An active explosion relief component, the active explosion relief component includes a detection structure and a driving structure detachably arranged on the cabinet door, the detection structure forms a communication connection with the driving structure to detect the temperature, pressure and gas concentration value inside the energy storage cabinet and form a detection signal, the driving structure includes a movable rod that moves relative to the explosion relief plate, and the movable rod has a first moving position. When the driving structure receives the detection signal, the movable rod moves to the first moving position, drives the explosion relief plate to rotate, and releases the blockage of the opening.

[0008] In the explosion venting device of an energy storage cabinet described above, the movable rod is arranged perpendicular to the explosion venting plate. When the movable rod moves to the first moving position, the movable rod abuts against the explosion venting plate and pushes the explosion venting plate to rotate away from the movable rod direction to release the blockage of the opening.

[0009] In the explosion venting device of an energy storage cabinet described above, the driving structure includes a driving member that forms a communication connection with the detection structure. The output end of the driving member is connected to the movable rod. When the driving member receives the detection signal, it drives the movable rod to move to the first moving position.

[0010] In the explosion venting device of an energy storage cabinet described above, the driving member is a driving motor, a driving cylinder, a hydraulic cylinder or a spring driving structure.

[0011] In the explosion venting device of an energy storage cabinet described above, one end of the explosion venting plate is rotatably connected to the cabinet door, and the other end is connected to the cabinet door through an explosion venting sheet. When the movable rod moves to the first moving position, the explosion venting sheet ruptures under the thrust of the movable rod, causing the explosion venting plate to rotate away from the movable rod direction.

[0012] In the explosion venting device of an energy storage cabinet described above, the explosion venting plate is rotatably connected to the cabinet door through a hinge structure.

[0013] In the explosion venting device of an energy storage cabinet described above, a strengthening frame is further provided on the side of the cabinet door facing the inside of the energy storage cabinet.

[0015] In the explosion venting device of an energy storage cabinet described above, the detection structure includes a temperature sensor, a pressure sensor and a gas sensor.

[0016] In the explosion venting device of an energy storage cabinet described above, a heat insulation plate is further included and is detachably arranged on the side of the explosion venting plate facing the driving structure.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: By arranging a rotatable explosion venting plate on the cabinet door, a detection structure for detecting the internal temperature, pressure and gas concentration value of the energy storage cabinet, and a driving structure that forms a communication connection with the detection structure, and enabling the driving structure to drive the explosion venting plate to rotate for active explosion venting according to the detection signal, the controllability and timeliness of explosion venting are effectively improved, thereby ensuring the reliability and safety of the explosion venting of the energy storage cabinet.

Specific embodiments

[0022] The following are specific embodiments of the present utility model in conjunction with the drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0023] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0024] As Figures 1 to 3 shown, an explosion venting device for an energy storage cabinet includes a cabinet door 100, an explosion venting structure 200, a detection structure 300, a driving structure 400, a strengthening frame 500, and a heat insulation plate 600.

[0025] As Figures 1 to 3 shown, an explosion venting device for an energy storage cabinet includes:

[0026] The cabinet door 100 is provided with an opening 110 thereon for releasing pressure during explosion venting;

[0027] The explosion venting structure 200 includes an explosion venting plate 210 rotatably arranged on the cabinet door 100 and forming a blockage for the opening 110;

[0028] The active explosion relief assembly includes a detection structure 300 and a drive structure 400 detachably disposed on the cabinet door 100. The detection structure 300 forms a communication connection with the drive structure 400 to detect the temperature, pressure and gas concentration value inside the energy storage cabinet and form a detection signal. The drive structure 400 includes a movable rod 410 that moves relative to the explosion relief plate 210, and the movable rod 410 has a first moving position. When the drive structure 400 receives the detection signal, the movable rod 410 moves to the first moving position, driving the explosion relief plate 210 to rotate, unblocking the opening 110, and realizing active explosion relief. This explosion relief method can actively start explosion relief when abnormal temperature, pressure or gas concentration inside the energy storage cabinet is detected, effectively improving the controllability and timeliness of explosion relief, thereby ensuring the reliability and safety of explosion relief of the energy storage cabinet.

[0029] Specifically, if Figures 1 to 3 As shown, in this embodiment, the energy storage cabinet includes at least one cabinet door 100, and a rectangular opening 110 is provided on the cabinet door 100 to release pressure during explosion relief to prevent the explosion relief from damaging the internal components of the energy storage cabinet.

[0030] In this embodiment, the side of the cabinet door 100 facing the inside of the energy storage cabinet is provided with an explosion relief structure 200, and the explosion relief structure 200 includes an explosion relief plate 210 rotatably provided on the cabinet door 100 and blocking the opening 110. On the one hand, the rotatable design enables the energy storage cabinet to vent explosions through the opening 110 when in the explosion relief state, and on the other hand, the blocking design enables the cabinet door 100 to be in a sealed state under normal circumstances to prevent the external environment from affecting the inside of the energy storage cabinet.

[0031] In this embodiment, the explosion relief plate 210 is rectangular, and its size is adapted to the opening 110 .

[0032] In this embodiment, one end of the explosion venting plate 210 is rotatably connected to the cabinet door 100, and the other end is connected to the cabinet door 100 through the explosion venting plate 220. The explosion venting plate 210 can be rotated away from the opening 110 by the rupture of the explosion venting plate 220 to achieve explosion venting. The design of the explosion venting plate 220 ensures that it can be quickly ruptured under the thrust of the movable rod 410, ensuring that the explosion venting plate 210 can be rotated in time.

[0033] It should be noted that the explosion venting piece 220 allows the explosion venting plate 210 to not only be pushed by the movable rod 410 to rupture the explosion venting piece 220 for active explosion venting, but also be ruptured by the explosion pressure to perform passive explosion venting, effectively enriching the explosion venting methods of the energy storage cabinet.

[0034] In this embodiment, the explosion vent panel 210 is rotatably connected to the cabinet door 100 through a hinge structure 230 at the other end. Preferably, there are two sets of the hinge structures 230 arranged in a line. This ensures the reliability of the connection between the explosion vent panel 210 and the cabinet door 100, and at the same time can prevent the explosion vent panel 210 from detaching from the cabinet door 100 after explosion and injuring people or other objects, effectively improving the safety of the explosion vent device.

[0035] To further improve the heat insulation performance of the energy storage cabinet, in this embodiment, it further includes a heat insulation panel 600 detachably arranged on the side of the explosion vent panel 210 facing the driving structure 400. The heat insulation panel 600 is made of materials such as rock wool, glass wool, ceramic fiber or composite materials. On the one hand, it can effectively reduce the influence of the external environment on the inside of the energy storage cabinet. On the other hand, it can also reduce the impact of hot air flow on the explosion vent panel 210 during explosion, effectively improving the service life of the energy storage cabinet and the explosion vent structure 200.

[0036] To achieve active explosion venting, in this embodiment, there is also an active explosion venting component. The active explosion venting component includes a detection structure 300 and a driving structure 400 detachably arranged on the side of the cabinet door 100 facing the inside of the energy storage cabinet. The detection structure 300 and the driving structure 400 are in communication connection, used to detect the temperature, pressure and gas concentration values inside the energy storage cabinet and form a detection signal as a condition for triggering the start of the driving structure 400. The driving structure 400 includes a movable rod 410 that moves relative to the explosion vent panel 210. The movable rod 410 has a first moving position, used to push the explosion vent panel 210 according to the detection signal, drive the explosion vent panel 210 to rotate, release the blockage of the opening 110, and achieve active explosion venting. Compared with the traditional passive explosion venting method, this active explosion venting method can perform explosion venting flexibly and actively according to the internal state of the energy storage cabinet. It not only effectively improves the controllability and timeliness of explosion venting, but also can give an early warning of the active explosion venting time to reserve time for personnel evacuation, further ensuring safety.

[0037] In this embodiment, the detection structure 300 includes a temperature sensor 310, a pressure sensor 320 and a gas sensor 330 arranged in a line and installed on the top of the reinforcing frame 500, used to detect the temperature, pressure and gas concentration values inside the energy storage cabinet respectively, realizing comprehensive monitoring of the internal state of the energy storage cabinet, improving the detection accuracy, and at the same time ensuring timely response in various abnormal situations.

[0038] In this embodiment, the driving structure 400 includes a driving part 420 arranged on the reinforcing frame 500 and in communication connection with the detection structure 300. The output end of the driving part 420 is connected to the movable rod 410. When the driving part 420 receives the detection signal, it drives the movable rod 410 to move to the first moving position. This enables the driving structure 400 to accurately control the movement of the movable rod 410 according to the detection signal and achieve effective driving of the movable rod 410.

[0039] In this embodiment, the driving member 420 is a driving motor or a driving cylinder or a hydraulic cylinder or a spring driving structure 400, which provides a variety of power source options for the explosion relief device, allowing users to flexibly configure it according to actual needs.

[0040] In this embodiment, the movable rod 410 is arranged vertically with the explosion venting plate 210. When the movable rod 410 moves to the first moving position, the movable rod 410 abuts against the explosion venting plate 210 and pushes the explosion venting plate 210 to rotate away from the movable rod 410, so as to release the blockage of the opening 110 and realize active explosion venting. This vertical arrangement ensures that the movable rod 410 can directly act on the explosion venting plate 210, quickly push the explosion venting plate 210 to rotate, reduce the response time, and improve the explosion venting efficiency.

[0041] In this embodiment, when the movable rod 410 moves to the first moving position, it abuts against the explosion venting plate 210 and applies a thrust to the explosion venting plate 210, so that the explosion venting plate 220 breaks under the thrust of the movable rod 410, thereby separating one end of the explosion venting plate 210 from the cabinet door 100 and rotating in a direction away from the movable rod 410.

[0042] In this embodiment, the movable rod 410 has a first moving position and a second moving position. When the movable rod 410 is in the first moving position, the end of the movable rod 410 extends into the opening 110. When the movable rod 410 is in the second moving position, the end of the movable rod 410 retracts outside the opening 110.

[0043] In order to improve the strength of the cabinet door 100, in this embodiment, a reinforcement frame 500 is further provided on the side of the cabinet door 100 facing the inside of the energy storage cabinet, and the reinforcement frame 500 is arranged circumferentially along the opening 110, and the driving structure 400 is detachably arranged on the reinforcement frame 500. The arrangement of the reinforcement frame 500 effectively improves the strength and stability of the cabinet door 100 opening, and further ensures the stability and integrity of the cabinet door 100 after explosion relief.

[0044] In this embodiment, the explosion relief plate 210 is connected to the end of the reinforcement frame 500 away from the hinge structure 230 through the explosion relief piece 220, which ensures the strength and reliability of the connection and improves the convenience of replacing the explosion relief piece 220 after it is damaged.

[0045] It should be noted that, in this embodiment, the driving structure 400 can be arranged at one end of the reinforcing frame 500 close to the hinge structure 230, or can be arranged at one end of the reinforcing frame 500 close to the explosion vent panel 220. In the former case, with the same moving stroke, the explosion vent plate 210 can be sprung open at a larger angle, realizing the rapid springing open of the explosion vent plate 210. In the latter case, the driving force required by the driving structure 400 can be reduced. Preferably, in this embodiment, the driving structure 400 is arranged at one end of the reinforcing frame 500 close to the hinge structure 230.
