[0002] Energy storage containers are an important part of energy stations such as photovoltaic power stations and wind-solar hybrid power stations. They include cabinets and energy storage batteries arranged in the cabinets. For each energy station, thermal runaway of energy storage batteries is a major safety threat. When thermal runaway occurs in energy storage batteries, a large amount of flammable gas will accumulate, and the pressure in the cabinet will increase rapidly, which may cause the cabinet to explode, seriously endangering the safety of other equipment and personnel around it.

[0015] The present invention has positive effects: (1) The present invention arranges a main fan in the inner cavity. The main fan sucks the smoke in the container under the drive of the main controller. At the same time, the main controller drives the valve plates to open both sides synchronously by driving the actuator. The double-door design can greatly enhance the exhaust efficiency of the main fan in the effective space. It has good adjustability and applicability. At the same time, by setting the position of each valve plate to be a certain distance away from the main fan and arranging an air outlet cylinder, it is effectively ensured that each valve plate is tightly and firmly pressed against the air outlet cylinder before and after exhaust, avoiding water vapor or other impurities from entering the inner cavity, ensuring the waterproofness of the inner cavity.

When one valve plate is damaged, exhaust can continue through the other valve plate, without affecting the overall exhaust efficiency and exhaust efficiency, thereby ensuring that the smoke in the container is comprehensively and efficiently exhausted. The structure is ingenious and convenient and practical.

[0016] (2) The present invention provides a bottom flange at the bottom of the valve plate, side flanges on the sides of each valve plate, and a waterproof rubber strip on the end face of the air outlet cylinder. On the one hand, it can effectively prevent impurities or water vapor from entering the inner cavity. On the other hand, the provision of the waterproof rubber strip further ensures the sealing of the connection between the valve plate and the air outlet cylinder. At the same time, each valve plate is arranged inside the air outlet slot, which greatly reduces the impact of severe weather such as wind, snow, and hail on the valve switch, and is convenient and practical.

[0017] (3) The present invention provides limiting side plates on both sides of the air outlet cylinder body, and forms limiting slots between the limiting side plates and the air outlet cylinder body. Through the cooperation between the side flange and the limiting slot, and the cooperation between the electromagnet and the magnetic attraction part, the firmness of the connection between each valve plate and the air outlet cylinder body is ensured, and the sealing of the connection between each valve plate and the air outlet cylinder body is further ensured, which is efficient and convenient.

[0018] (4) The present invention integrates the driven shaft into an integral shape with a rotating shaft portion having a circular cross section and a connecting portion having a square cross section. The circular rotating shaft portion ensures the smoothness of the rotation of the driven shaft. The square connecting portion is in contact with the valve plate surface, which further improves the sealing performance of the connection between the valve plate and the exhaust cylinder body, as well as the stability of the connection between the valve plate and the driven shaft. The present invention is practical and convenient.

[0019] (5) The present invention arranges a debris removal component in the air outlet slot. The first rotating rod drives the second rotating rod and the sliding block on the second rotating rod to slide under the drive of the driven shaft. When the valve plate is opened, the debris removal block can be driven synchronously, thereby driving the debris removal block to discharge the accumulated water, snow and impurities in the air outlet slot, effectively avoiding the blockage of the air outlet slot by snow, impurities or hail, which affects the overall air outlet effect. It is efficient and convenient.

[0020] (6) The present invention realizes rotational connection between the first rotating rod and the second rotating rod through a connecting shaft. The cooperation between the connecting shaft and the side arc groove ensures the rotation limit of the first rotating rod and the second rotating rod. The cooperation between the sliding block and the side slide groove, as well as the cooperation between the side sliding block and the side slide groove ensures the stability of the sliding block and the debris removal block during the debris removal process. At the same time, the debris removal formation of the debris removal block is also limited by the limit, so as to avoid the separation of the debris removal block and the air outlet slot. The present invention is stable and practical.

[0021] (7) The present invention arranges the debris removal groove to be a combination of a guide slope, an arc-shaped guide surface and a discharge slope. The guide slope guides the accumulated water, snow and impurities for debris removal. On the one hand, the arc-shaped guide surface can smoothly guide the accumulated water, snow and impurities to the discharge slope. On the other hand, the arrangement of the arc-shaped guide surface can also greatly avoid the accumulation of impurities, snow or large hail during the debris removal process, thereby ensuring the comprehensive and efficient discharge of snow, impurities or hail, which is convenient and practical.

[0022] (8) The present invention provides a debris removal part, and the debris removal part is arranged in a triangular shape. The debris removal part is pressed against the bottom surface of the air outlet slot through the cooperation of the side rotating rods and the rotating holes, and the continuous force of the torsion spring. The debris removal part removes the accumulated water, snow or impurities from the bottom during the movement of the debris removal block, thereby ensuring the comprehensiveness and efficiency of the removal of the accumulated water, snow or impurities in the air outlet slot. The invention is practical and convenient.

[0023] (9) The present invention provides a valve opening and closing detection device to monitor the opening and closing status of the valve plate in real time, thereby ensuring that the operator can detect the exhaust condition in the inner cavity in real time, avoiding the situation where the actuator and the valve plates driven by the actuator fail and the smoke cannot be discharged, thereby ensuring that the smoke in the container can be discharged safely and effectively. It is safe and practical.

[0024] (10) The present invention sets up a sub-controller, which is powered by a battery. After the main controller loses power, each bottom sealing plate opens the corresponding bottom air outlet through the continuous force of the compression spring on the limit slide rod. The sub-controller drives each spare fan to suck the smoke in the container. The lifting block drives the screw rod through the auxiliary motor, and the screw rod and the lifting screw hole are slidably arranged in the sliding groove of the push door rod. The push door guide wheel pushes each valve plate to open through the lifting of the lifting block, thereby realizing the main controller driving the valve plate after power failure, thereby realizing the exhaust of smoke in the container after the main controller loses power. The invention is stable, convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

The inner contour is the same as the contour of the air outlet 2a, and the air outlet groove 20 is connected with the air outlet 2a through the air outlet cylinder 2b. Before the actuator 51 is started, each valve plate 57 is pressed against the end surface of the corresponding air outlet cylinder 2b away from the air outlet 2a and closes the inner cavity. When the main fan 27 is started, each valve plate 57 is synchronously disengaged from the air outlet cylinder 2b through the driving of the transmission shaft 52 by the actuator 51, the driving of each follower rod 54 by the connecting block 53, and the driving of the rotating block 55 by each follower rod 54. The main fan 27 discharges the gas after each valve plate 57 is disengaged from the air outlet cylinder 2b.

[0027] The bottom of each valve plate 57 is provided with a bottom flange 572 integrally formed with the valve plate 57, and each side of each valve plate 57 is provided with a side flange 571 integrally formed with the valve plate 57. The side flanges 571 on the valve plate 57 are arranged relatively to each other, and the bottom flange 572 extends toward one side of the air outlet cylinder body 2b in a direction perpendicular to the valve plate 57, and each side flange 571 extends toward one side of the air outlet cylinder body 2b in a direction perpendicular to the valve plate 57. A waterproof rubber strip 573 is provided on the end surface of each air outlet cylinder body 2b away from the inner cavity.

[0028] The bottom flange 572 and the side flange 571 on the valve plate 57 are folded toward the side of the air outlet cylinder body 2b through the bottom flange 572 and the side flange 571, and the tightness and sealing of the connection between the valve plate 57 and the air outlet cylinder body 2b are ensured by the waterproof rubber strip 573. On the other hand, water or snow can enter the inner cavity of the main shell 2 during bad weather such as rain, snow, hail, etc., to ensure that each valve plate 57 opens synchronously and smoothly. At the same time, it can also prevent water and snow from freezing between the valve plate 57 and the air outlet cylinder body 2b, greatly reducing the fixation between the air outlet cylinder body 2b and the valve plate 57 due to freezing, thereby effectively reducing the influence of bad weather on the opening and closing of the valve plate 57.

[0029] A limiting side plate 2c is provided on both sides of each air outlet cylinder body 2b, one end of each limiting side plate 2c is integrally formed with the air outlet cylinder body 2b, and the other side of each limiting side plate 2c is flipped toward one side of the side flange 571 along a direction perpendicular to the valve plate 57, and each side flange 571 is provided with a magnetic attraction portion 574, and each limiting side plate 2c is provided with an electromagnet 2d corresponding to each magnetic attraction portion 574 and electrically connected to the main controller 11, and each limiting side plate 2c forms a limiting slot 2e with the side of the air outlet cylinder body 2b, and each valve plate 57 is positioned and connected to the main shell 2 through the plug-in cooperation with the limiting slot 2e of each side flange 571 before the actuator 51 is started or after the exhaust is completed, and the magnetic attraction cooperation of each electromagnet 2d and the magnetic attraction portion 574.

[0030] The structural design of the double-doors on the side can greatly enhance the exhaust efficiency of the main fan 27 within the effective space. At the same time, the positions of the two valve plates 57 are kept away from the main fan 27 in the inner cavity, which can greatly improve the overall waterproofness.

[0031] The electromagnet 2d is energized when there is no need to exhaust in the container or after the exhaust is completed. After the energized electromagnet 2d enters the limiting slot 2e on the limiting side plate 2c, it cooperates with the magnetic attraction of the magnetic attraction part 574 to further ensure the firmness and stability of the connection between the valve plate 57 and the exhaust cylinder body 2b, thereby avoiding the shaking of each valve plate 57 during the container transportation, and thus ensuring the overall airtightness of the inner cavity when the exhaust is not carried out.

[0032] The driven shaft 56 includes a rotating shaft portion 561 which is rotatably connected to each side wall of the air outlet slot 20 and has a circular cross-section, and a connecting portion 562 which is arranged between each rotating shaft portion 561 and has a square cross-section. The connecting portion 562 is integrally formed with each rotating shaft portion 561, and each valve plate 57 is fixed to the connecting portion 562 by a locking member to form a surface contact with the connecting portion 562.

[0033] The driven shaft 56 is configured to cooperate with a rotating shaft portion 561 and a connecting portion 562. The cross-section of the rotating shaft portion 561 is configured to be circular, which ensures the smooth rotation of the valve plate 57. The cross-section of the connecting portion 562 is configured to be square rather than circular, and the contact area can be increased by the surface contact between the valve plate 57 and the connecting plate, thereby ensuring the sealing of the connection between the valve plate 57 and the driven shaft 56. If the connecting portion 562 is configured to be circular, then a line contact is formed between the connecting portion 562 and the valve plate 57, and the sealing of the line contact is obviously not as good as the sealing of the surface contact. Therefore, the driven shaft 56 is configured to cooperate with the rotating shaft portion 561 and the connecting portion 562, which can not only ensure the smooth rotation of the driven shaft 56, but also ensure the efficient sealing of the connection between the valve plate 57 and the connecting portion 562.

[0034] Each air outlet slot 20 is provided with a debris removal component 6 for discharging accumulated water or snow in the air outlet slot 20.

[0043] Working principle of the present invention: During the operation of the present invention, a gas detector is installed in the external control box 1, and the gas detector is electrically connected to the main controller 11. When the gas detector senses smoke in the container, the main controller 11 drives the main fan 27, and at the same time, the main controller 11 sends a driving signal to the actuator 51 and sends a power-off signal to the electromagnet 2d, so that the magnetic attraction between the electromagnet 2d and the magnetic attraction part 574 is cancelled, and the main controller sends a driving signal to the bottom cylinder 43, and the bottom cylinder 43 drives the bottom sealing plate 45 to slide, thereby closing the bottom air outlet 29, and the actuator 51 drives the transmission shaft 52 and the connecting block 53 on the connecting shaft 67 to rotate, and the connecting block 53 drives each driven rod 54 to move, and each driven rod 54 drives each rotating block 55 and the driven shaft 56 to rotate, thereby realizing the synchronous opening of each valve plate 57. Setting two valve plates 57 that can be opened synchronously can greatly improve the exhaust efficiency on the one hand, and on the other hand, when one valve plate 57 is damaged, the exhaust can continue through the other valve plate 57; During the opening process of each valve plate 57, each side flange 571 disengages from the limiting slot 2e, and during the disengagement process, the driven shaft 56 drives the first rotating rod 61 to rotate, and the first rotating rod 61 drives the second rotating rod 62 to move upward. During the upward movement, the second rotating rod 62 drives the sliding block 64 in the side sliding groove 63, and the sliding limit and anti-separation of the sliding block 64 are performed through the cooperation of the limiting slider 641 and the limiting sliding groove 631. During the sliding process of each sliding block 64, the cleaning block 66 is driven to move toward the opening of the air outlet slot 20. Before the debris removal block 66 moves, the debris removal part 7 is pressed against the bottom surface of the air outlet slot 20 by the cooperation of the side rotating rods 72 and the rotating holes 601, and the continuous force of the torsion spring 602. During the movement of the debris removal block 66, the impurities are discharged through the cooperation of the triangular debris removal part 7, the guide slope 691, the arc-shaped guide surface 692 and the outlet slope 693. On the one hand, it can ensure the rapid discharge of smoke in the container, and on the other hand, it can also ensure the rapid discharge of impurities, accumulated water or snow in the air outlet slot 20, thereby ensuring the smoothness of exhaust. After the smoke is discharged, each valve plate 57 is reset, and each valve plate 57 enters the limit slot 2e through the lower flange 571 driven by the driven shaft 56, and timely signal feedback is provided through the valve opening and closing detection device 252, so that the operator can timely understand the specific working conditions in the inner cavity, and prevent damage caused by the failure of the actuator 51 that causes the smoke to be unable to be discharged. The electromagnet 2d and the magnetic attraction part 574 cooperate to ensure the stability of the connection between each valve plate 57 and the main shell 2 after resetting, as well as the sealing degree of the inner cavity.

[0044] After the main controller 11 loses power, each bottom sealing plate 45 opens the corresponding bottom air outlet 29 through the continuous force of the compression spring 48 on the limit slide rod 46. The operator can drive each standby fan 16 to discharge the smoke in the container by pressing the control switch 15. At the same time, the auxiliary controller 13 drives the auxiliary motor 32 to drive the screw rod 33 to rotate the push rod 34. During the downward rotation of the push rod 34, the push door guide wheel 37 presses on the valve plate 57 to open the valve plate 57. At the same time, when the valve plate 57 is opened, the push door guide wheel 37 is pressed against the valve plate 57. During the process, the driven shaft 56 is driven to rotate, and the impurity removal block 66 is driven to push out the accumulated water, snow or impurities in the wind slot 20 for removal. The operator can regularly check and replace the battery 14. After the impurity removal is completed, each push door guide wheel 37 is separated from the valve plate 57, and each valve plate 57 is reset under the action of its own weight. Two auxiliary push door assemblies 3 are arranged in the inner cavity, which can simultaneously drive each valve plate 57 to open, and can also reduce the damage to the transmission shaft 52 on the actuator 51; The present invention effectively solves the problem in the prior art that the gas cannot be discharged in time, and the high-temperature gas will cause great damage to the energy storage container and the batteries in the energy storage container. Through the setting of double doors, efficient exhaust can be achieved in an effective space. At the same time, the debris removal block 66 can also effectively avoid blockage in the air outlet slot 20. Through the auxiliary push door assembly 3, the double door can be opened even when the main controller 11 is powered off, thereby comprehensively, efficiently and safely ensuring the efficient discharge of smoke in the container. The structure is ingenious and convenient and practical.
