[0041] See also Figures 1 to 5 In this embodiment, an exhaust device for exhausting gas from an energy storage cabinet is proposed, which includes a frame 1, a mounting structure 2, an exhaust fan, and a sealing opening and closing structure 3. The frame 1 is sealed and arranged on the energy storage cabinet; the mounting structure 2 is sealingly connected to the frame 1 and has a mounting hole 211; the mounting structure 2 is sealingly connected to the frame 1 and has a mounting hole 211; the exhaust fan is arranged in the mounting hole 211 and is used to exhaust gas from the interior of the energy storage cabinet; the sealing opening and closing structure 3 is arranged on the frame 1 and is located outside the exhaust fan. The sealing opening and closing structure 3 has a closed state in which the mounting hole 211 is sealed and an open state in which the mounting hole 211 is opened. When the sealing opening and closing structure 3 is in the closed state, it cooperates with the mounting structure 2 to seal the mounting hole 211. When the sealing opening and closing structure 3 is in the open state, the mounting hole 211 is connected to the outside of the energy storage cabinet.

[0042] It is understood that the frame 1 is sealed against the energy storage cabinet body, the mounting structure 2 is sealed against the frame 1, and under the action of the exhaust fan, the gas inside the energy storage cabinet can be discharged through the mounting hole 211. The sealing opening and closing structure 3 can seal or open the mounting hole 211. When the sealing opening and closing structure 3 is in the open state, the gas inside the energy storage cabinet can be discharged to prevent gas accumulation inside the energy storage cabinet. When the sealing opening and closing structure 3 is in the closed state, the mounting hole 211 can be sealed to prevent debris from entering the interior of the energy storage cabinet, thereby improving the protective performance of the energy storage cabinet and, in turn, the safety performance of the energy storage cabinet. In addition, the wind force of the exhaust fan can prevent external debris from entering the interior of the energy storage cabinet, thereby ensuring the protective performance of the energy storage cabinet when the sealing opening and closing structure 3 is in the open state.

[0043] Furthermore, the mounting structure 2 includes a mounting portion 21, an extension portion 22, and a sealing portion 23. The mounting portion 21 and the extension portion 22 are sealed together, and a mounting hole 211 is provided in the mounting portion 21. One end of the extension portion 22 is sealed together with the frame 1, and the other end can extend to the sealed opening and closing structure 3, with the extension portion 22 surrounding the mounting hole 211. The sealing portion 23 is squeezed between the extension portion 22 and the sealed opening and closing structure 3. The sealing portion 23 is preferably made of foam. In actual use, the mounting portion 21 is vertically disposed inside the frame 1 and is sealed to the frame 1 via the extension portion 22, thereby preventing debris from entering the interior of the energy storage cabinet through the gap between the mounting structure 2 and the frame 1.

[0044] Exemplarily, the extension portion 22 includes a plurality of extension plates 221 , which are arranged around the mounting hole 211 , thereby sealing the area between the mounting structure 2 and the sealing opening and closing structure 3 to prevent external debris from entering the interior of the energy storage cabinet through the mounting hole 211 . Among them, each extension plate 221 includes a first plate 2211, a second plate 2212, a third plate 2213, a fourth plate 2214 and a fifth plate 2215 which are arranged vertically in sequence. The sealing portion 23 is squeezed between the first plate 2211 and the sealing opening and closing structure 3. The third plate 2213 can fit with the mounting portion 21, thereby increasing the connection strength between the extension plate 221 and the sealing opening and closing structure 3. The fourth plate 2214 is arranged parallel to the second plate 2212 and extends in a direction away from the first plate 2211. The fifth plate 2215 can extend to the frame 1. Among them, the fourth plate 2214, the fifth plate 2215 and the frame 1 can be assembled into an installation space to accommodate the sealing opening and closing structure 3, thereby improving the space utilization of the frame 1.

[0045] In this embodiment, the sealing and opening and closing structure 3 includes a rotating portion 31 and a sealing portion 32. The rotating portion 31 is disposed on the frame 1. The sealing portion 32 has a closed state, sealing the mounting hole 211, and an open state, opening the mounting hole 211. The sealing portion 32 is disposed at the rotating end of the rotating portion 31, and the rotating portion 31 is capable of driving the sealing portion 32 to switch between the closed and open states. It is understood that the rotating portion 31 is disposed within the installation space to improve the space utilization of the frame 1. Under the action of the rotating portion 31, the sealing portion 32 can be abutted against the sealing portion 23 to seal the mounting hole 211.

[0046] Furthermore, the closing portion 32 includes a closing plate 321 and a flange 322. The closing plate 321 is disposed at the rotating end of the rotating portion 31, and the side surface of the closing plate 321 can abut against the sealing portion 23. The flange 322 is disposed on the circumferential side of the closing plate 321, and the flange 322 extends toward one side of the sealing portion 23 and extends to the area where the extension portion 22 is located. It is understood that after rotation, the closing plate 321 can squeeze the sealing portion 23. Since the force applied to different parts of the closing plate 321 is uneven, the degree of deformation of the sealing portion 23 caused by squeezing also varies, which can easily lead to a gap between the closing plate 321 and the sealing portion 23. The flange 322 can block the gap, thereby further improving the protective performance of the exhaust device and preventing external debris from entering the interior of the energy storage cabinet.

[0047] Furthermore, the mounting portion 21 includes a rotating motor and a connector. The rotating motor is mounted on the frame 1, and the connector is mounted at the rotating end of the rotating motor. The connector is used to connect to the flange 322. It is understood that the connector is mounted at the rotating end of the rotating motor and can extend toward the closed portion 32, and the flange 322 can be connected to the connector. The flange 322 is preferably L-shaped to facilitate connection between the closed plate 321 and the connector.

[0048] Furthermore, the exhaust device also includes a gas concentration sensor 4, which is mounted on the frame 1 and is used to detect the gas concentration inside the energy storage cabinet. The gas concentration sensor 4 is electrically connected to the rotating portion 31. It is understood that when the gas concentration inside the energy storage cabinet reaches a threshold value of the gas concentration sensor 4, the gas concentration sensor 4 transmits a signal to the rotating motor, thereby opening the sealing plate 321 and activating the exhaust fan to exhaust the gas.

[0049] In this embodiment, the sealing plate 321 is provided with a plurality of explosion venting grooves 3211, the openings of which all face the interior of the energy storage cabinet. It will be appreciated that the provision of explosion venting grooves 3211 on the sealing plate 321 can reduce the local thickness of the sealing plate 321. When the gas pressure inside the energy storage cabinet increases, the explosion can be vented through the explosion venting grooves 3211, thereby avoiding safety accidents caused by excessive pressure, thereby further improving the safety performance of the exhaust device. The depth of each explosion venting groove 3211 is one-sixth to one-fifth of the thickness of the sealing plate 321, to facilitate explosion venting.

[0050] Preferably, the plurality of explosion relief grooves 3211 are staggered. It is understandable that the staggered explosion relief grooves 3211 can converge at one point to form an explosion relief point, thereby further facilitating explosion relief.

[0051] Exemplarily, the thickness of the closing plate 321 is 1.2 mm, and two explosion relief grooves 3211 with a depth of 0.2 mm are provided on the closing plate 321 , and the intersection center of the two explosion relief grooves 3211 is located at the center of the closing plate 321 .

[0052] Based on the above, this embodiment further provides an energy storage cabinet comprising a cabinet body and the aforementioned exhaust device, with a frame 1 sealed within the cabinet body. The exhaust device promptly exhausts gas from within the cabinet body, thereby preventing gas accumulation within the cabinet body and ensuring the protective performance of the energy storage cabinet.

[0053] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
