Description

Technical Field

[0001] The present application relates to the field of ventilation equipment technology, and in particular to a reinforced sealed ventilation window. Background Art

[0002] The energy storage container is an integrated energy storage system that integrates energy storage battery systems, battery management systems, energy storage inverters and other auxiliary equipment. It uses a standardized container as the shell to package these key components together to form a compact, efficient, easy-to-transport and install energy storage unit.

[0003] The energy storage container fire protection system uses automated control and monitoring technology to monitor the fire and smoke in the container in real time. Once an abnormality is detected, the system will automatically alarm and activate the fire extinguishing device to extinguish the initial fire and prevent the fire from spreading, thereby ensuring the safety of personnel, materials and equipment in the container. However, when a fire occurs inside the energy storage container and the fire is difficult to control through a conventional gas fire extinguishing system, direct water injection fire extinguishing will be considered. Water injection fire extinguishing is to directly inject water into the container so that the injected water directly fills the container to achieve a fire extinguishing effect.

[0004] The walls of energy storage containers are usually equipped with ventilation windows. The ventilation windows are used in scenarios where the concentration of combustible gas is high and ventilation is required to output flammable and explosive gases outside the container. A baffle is provided outside the ventilation window to seal the ventilation window when ventilation is not required. Since the sealing and fixing effect between the baffle and the ventilation window in traditional ventilation windows is limited, although the sealing effect can be achieved, when water is injected into the container, the water pressure in the container increases, and the thrust on the baffle increases, and the baffle is prone to loosening, resulting in water leakage between the baffle and the ventilation window. On the one hand, it affects the efficiency of water injection and fire extinguishing. In addition, the leaked water may carry electricity and other pollutants, which will not only threaten the safety of personnel, but also may have an impact on the environment. Summary of the invention

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-13 This application is described in further detail.

[0038] The present application discloses a reinforced sealed ventilation window. Figure 1 The reinforced sealed ventilation window includes a frame 1, which is installed on a target device that needs ventilation. The target device may be an energy storage box, a distribution box or other power equipment. The target device in the embodiment of the present application refers to an energy storage container.

[0039] The frame 1 is fixedly connected to the energy storage container, and a vent 11 is provided on the frame 1 for realizing gas circulation inside and outside the energy storage container. A baffle 12 is hinged on the frame 1, and the operator can open and close the vent 11 by flipping the baffle 12.

[0040] like Figure 2 and Figure 3 In the embodiment of the present application, the baffle 12 is hinged to the frame 1 through the rotating shaft 13, and the rotating shaft 13 is connected to the frame 1 through the connecting device 6. The rotating shaft 13 extends into the frame 1, and a control device 2 for controlling the rotation of the rotating shaft 13 is provided in the frame 1.

[0041] like Figure 4 and Figure 5In order to improve the sealing of the baffle 12 when it is closed, the baffle 12 can be prevented from accidentally opening under the action of water pressure when the fire in the energy storage container is out of control and water is poured to extinguish the fire. In the embodiment of the present application, the baffle 12 and the frame 1 can be locked together when closed to reduce the possibility of opening by external force.

[0042] The baffle 12 is fixedly connected to the limit block 3 on the side wall facing the frame 1, and the frame 1 is provided with a lock buckle 4 for interlocking with the limit block 3. The lock buckle 4 is movably arranged on the frame 1, and a driving device 5 for controlling the movement of the lock buckle 4 is provided on the frame 1. When the driving device 5 controls the movement of the lock buckle 4, it can drive the lock buckle 4 to engage with the limit block 3 or disengage from the limit block 3.

[0043] like Figure 2 and Figure 4 The control device 2 may be a motor that drives the rotating shaft 13 to rotate through a transmission member such as a gear mechanism, a pulley mechanism, or a worm gear mechanism, or may be an electric push rod 21 that drives the rotating shaft 13 to rotate through a transmission member such as a linkage rod, a gear rack mechanism, or the like.

[0044] In the embodiment of the present application, the control device 2 includes an electric push rod 21 hinged in the frame 1, and a flip rod 22 is hinged on the piston rod of the electric push rod 21, and the flip rod 22 is fixedly connected to the rotating shaft 13. The operator controls the extension and retraction of the electric push rod 21 to drive the flip rod 22 to rotate, thereby driving the rotating shaft 13 to rotate, and finally achieving the flipping effect of the baffle 12.

[0045] like Figure 6 and Figure 7 The connecting device 6 includes a connecting seat 61 fixedly connected to the rotating shaft 13, a rotating seat 62 is rotatably connected to the connecting seat 61, and the rotating seat 62 is fixedly connected to the baffle 12. A limit assembly 7 is arranged between the connecting seat 61 and the rotating seat 62, and the limit assembly 7 is used to control the rotation angle of the rotating seat 62 on the connecting seat 61, thereby controlling the flip angle of the baffle 12 relative to the rotating shaft 13.

[0046] The limiting assembly 7 includes a support arm 71 fixedly connected to the rotating seat 62. The connecting seat 61 is provided with a limiting groove 72, and the support arm 71 extends into the limiting groove 72. When the rotating seat 62 rotates relative to the connecting seat 61, the support arm 71 abuts against one groove wall of the limiting groove 72. When the rotating seat 62 rotates in the opposite direction relative to the connecting seat 61, the support arm 71 abuts against the other groove wall of the limiting groove 72. In this way, the rotation angle of the rotating seat 62 on the connecting seat 61 is limited, and then the baffle 12 can rotate relative to the rotating shaft 13 by a preset rotation angle.

[0047] The two groove walls in the limiting groove 72 used to abut the support arm 71 are respectively recorded as the first limiting surface 73 and the second limiting surface 74. When the baffle 12 rotates on the rotating shaft 13 toward the open state, the support arm 71 on the rotating seat 62 abuts against the first limiting surface 73 on the connecting seat 61, and the second limiting surface 74 is arranged opposite to the first limiting surface 73.

[0048] like Figure 3 and Figure 4 , the driving device 5 can be a crank-connecting rod linkage mechanism, a gear 53 rack 52 linkage mechanism, or a pulley linkage mechanism. In the embodiment of the present application, the driving device 5 includes a moving seat 51 slidably arranged on the frame 1, and the moving seat 51 is fixedly connected to the lock buckle 4, so that the lock buckle 4 is slidably arranged in the frame 1. A gear 53 is coaxially fixedly connected to the rotating shaft 13, and a rack 52 is fixedly connected to the moving seat 51, and the gear 53 and the rack 52 are meshed with each other. The rotation of the rotating shaft 13 drives the gear 53 to flip, and under the meshing transmission action of the gear 53 and the rack 52, the moving seat 51 is driven to move, thereby driving the lock buckle 4 to move, so as to drive the limit block 3 and the lock buckle 4 to be engaged or separated.

[0049] like Figure 8 and Fig. 9 The lock 4 includes a sleeve 41 slidably disposed on the frame 1, and the sleeve 1 is fixedly connected to the movable seat 51. An insertion rod 42 is inserted into the sleeve 41, and an end plate 43 is disposed at the end of the insertion rod 42, and the end plate 43 is slidably disposed in the sleeve 41, so that the insertion rod 42 is slidably disposed in the sleeve 41 through the end plate 43. An elastic member 44 is disposed in the sleeve 41, and the elastic member 44 is used to push the end plate 43 so that the insertion rod 42 tends to retract into the sleeve 41. The elastic member 44 can be an elastic plate, a tension spring or a spring. The elastic member 44 in the embodiment of the present application is a spring, which is located in the sleeve 41 and pushes the end plate 43 to tend to abut against the inner wall of one end of the sleeve 41, so that the insertion rod 42 tends to retract into the sleeve 41.

[0050] like Fig.10 and Fig.11 , the limit block 3 is provided with a socket 31 for inserting the plug rod 42. When the baffle 12 is closed, the socket 31 on the limit block 3 can be aligned with the plug rod 42. A first magnet 32 ​​is fixedly connected to the socket 31, and the end of the plug rod 42 facing the outside of the sleeve 41 can be attracted by the first magnet 32. Under the attraction of the first magnet 32, the plug rod 42 can overcome the elastic force of the spring and extend out of the sleeve 41, and the plug rod 42 is inserted into the socket 31 of the limit block 3, so as to achieve a locking effect between the sleeve 41 and the limit block 3, thereby achieving the effect of locking the baffle 12 on the frame 1. When the socket 31 and the plug rod 42 are offset, the plug rod 42 on the lock buckle 4 retracts into the sleeve 41 under the action of the spring.

[0051] like Figure 6 and Fig.10 , the baffle 12 is closed, the baffle 12 is in a locked state, and the insertion rod 42 is inserted into the insertion hole 31, and this state is recorded as state a; like Figure 6 and Fig.12 , the baffle 12 is closed, the baffle 12 is in an unlocked state, and the insertion rod 42 is out of the insertion hole 31, and this state is recorded as state b; like Figure 6 and Fig.13 , the baffle 12 is opened and is in an unlocked state, at which time the insertion rod 42 is out of the insertion hole 31, and this state is recorded as state c.

[0052] like Fig.10 and Fig.11 State a: The baffle 12 is closed and in a locked state. At this time, the insertion hole 31 is aligned with the insertion rod 42. In this state, the support arm 71 on the connecting seat 61 abuts against the second limiting surface 74 on the rotating seat 62, and the moving seat 51 and the lock buckle 4 are arranged close to the limiting block 3 under the meshing linkage of the gear 53 and the rack 52. At this time, the insertion rod 42 on the lock buckle 4 overcomes the elastic member 44 under the attraction of the first magnet 32 ​​and extends out, and is inserted into the insertion hole 31, so that the position of the baffle 12 on the frame 1 is fixed.

[0053] like Fig.10 and Fig.12 , ab state: the baffle 12 is closed and gradually unlocked. During this process, the control device 2 drives the rotating shaft 13 to flip, so that the support arm 71 on the connecting seat 61 gradually moves away from the second limiting surface 74 and approaches the first limiting surface 73; at the same time, the rotating shaft 13 rotates, and under the meshing linkage action of the gear 53 and the rack 52, the sleeve 41 and the plug rod 42 corresponding to the lock buckle 4 move in the direction away from the socket 31 of the limit block 3, so that the plug rod 42 is gradually pulled out of the socket 31 until the plug rod 42 is completely out of the socket 31, thereby achieving the unlocking effect.

[0054] like Fig.12 and Fig.13 , bc state: the baffle 12 gradually opens, the baffle 12 remains unlocked, the control device 2 drives the shaft 13 to continue to flip, until the arm 71 contacts the first limit surface 73, and then drives the baffle 12 to gradually open, so that the insertion hole 31 and the insertion rod 42 are staggered, the attraction effect of the first magnet 32 ​​on the insertion rod 42 is released, and the insertion rod 42 is retracted into the sleeve 41 under the action of the spring. The shaft 13 continues to flip until the baffle 12 is completely in the open state.

[0055] like Fig.10 and Fig.13,ca state: the baffle 12 gradually closes, the baffle 12 remains unlocked, the control device 2 drives the rotating shaft 13 to flip in the opposite direction, the baffle 12 fits the first limit surface 73 under the action of gravity, and tends to close with the rotating shaft 13; when the baffle 12 is completely closed, the state of the connecting seat 61 and the rotating seat 62 changes from synchronous rotation to relative rotation. During this process, the support arm 71 changes from abutting the first limit surface 73 to abutting the second limit surface 74, so that the baffle 12 can be tightly pressed against the frame 1; in the process of closing the baffle 12, the rotating shaft 13 drives the gear 53 to flip, and under the meshing linkage action of the gear 53 and the rack 52, the moving seat 51 and the lock buckle 4 slide in the opposite direction.

[0056] like Fig.10 and Fig.11 , back to state a: at the moment when the baffle 12 is completely in contact with the frame 1, the insertion rod 42 on the lock buckle 4 is aligned with the insertion hole 31 on the limit block 3. In this state, the support arm 71 on the connecting seat 61 is in contact with the second limit surface 74 on the rotating seat 62. At this time, the moving seat 51 and the lock buckle 4 are arranged close to the limit block 3 under the meshing linkage of the gear 53 and the rack 52. At this time, the insertion rod 42 on the lock buckle 4 extends out of the sleeve 41 under the attraction of the first magnet 32 ​​and is inserted into the insertion hole 31, so that the position of the baffle 12 on the frame 1 is fixed and the baffle 12 is locked.

[0057] A limit rod 8 is slidably disposed on the sleeve 41, and the sliding direction of the limit rod 8 is perpendicular to the sliding direction of the insertion rod 42 in the sleeve 41. The end plate 43 is provided with a limit hole 81 for inserting the limit rod 8, and a second magnet 82 is disposed in the limit hole 81. The second magnet 82 is used to attract the limit rod 8 to insert into the limit hole 81, thereby limiting the insertion rod 42 from extending out of the sleeve 41.

[0058] like Fig. 9 and Figure 5 , the limiting rod 8 partially extends out of the sleeve 41, and the portion of the limiting rod 8 outside the sleeve 41 is fixedly connected to the push plate 83, and a push assembly is provided on the baffle 12, and the push assembly includes a push block 84 fixedly connected to the baffle 12, and the push block 84 is used to push the push plate 83. When the baffle 12 is closed, the push block 84 pushes the push plate 83, so that the limiting rod 8 can be separated from the limiting hole 81, and the limiting effect of the limiting rod 8 on the insertion rod 42 is released.

[0059] like Fig. 9 and Fig.11The limiting rod 8 is provided with a first inclined surface 85, and the side of the end plate 43 facing away from the insertion rod 42 is provided with a second inclined surface 86. In the process of the insertion rod 42 from the state of extending from the sleeve 41 to the state of retracting into the sleeve 41, the first inclined surface 85 abuts against the second inclined surface 86 and pushes the limiting rod 8 to gradually extend out of the sleeve 41. When the insertion rod 42 is completely retracted into the sleeve 41, the limiting hole 81 is aligned with the limiting rod 8, and under the attraction of the second magnet 82, the limiting rod 8 is inserted into the limiting hole 81.

[0060] like Fig. 9 When the baffle 12 is not completely closed, the insertion rod 42 remains retracted into the sleeve 41 under the action of the elastic member 44. In this state, the limiting rod 8 remains inserted into the socket 31 under the attraction of the second magnet 82 to prevent the insertion rod 42 from accidentally extending.

[0061] like Fig.11 When the baffle 12 is fully closed, the push block 84 pushes the push plate 83, so that the limiting rod 8 can be separated from the limiting hole 81, thereby releasing the limiting effect of the limiting rod 8 on the insertion rod 42. At this time, the insertion rod 42 can be inserted into the insertion hole 31 under the attraction of the first magnet 32, thereby achieving the effect of mutual locking of the baffle 12 and the frame 1.

[0062] like Fig.10 and Fig.11 In the process of opening the baffle 12, the baffle 12 needs to be unlocked first. In this process, the piston rod of the electric push rod 21 moves to drive the rotating shaft 13 to rotate, so that the rotating shaft 13 and the baffle 12 are flipped over each other. Under the meshing linkage of the gear 53 and the rack 52, the lock 4 moves away from the limit block 3, so that the plug rod 42 gradually disengages from the insertion hole 31, thereby releasing the clamping effect between the limit block 3 and the lock 4. The electric push rod 21 continues to push the rotating shaft 13 to rotate, so that the support arm 71 abuts against the first limit surface 73, and drives the baffle 12 to gradually flip and open. The baffle 12 flips relative to the frame 1 and tends to open, so that the insertion hole 31 gradually staggers with the plug rod 42, so that the first magnet 32 ​​staggers with the plug rod 42. After the first magnet 32 ​​releases the attraction to the plug rod 42, the plug rod 42 gradually retracts into the sleeve 41 under the action of the first elastic member 44.

[0063] During the process of retracting the insertion rod 42 into the sleeve 41, the first inclined surface 85 abuts against the second inclined surface 86 and pushes the limiting rod 8 to gradually extend out of the sleeve 41. When the insertion rod 42 is completely retracted into the sleeve 41, the limiting hole 81 is aligned with the limiting rod 8. Under the attraction of the second magnet 82, the limiting rod 8 is inserted into the limiting hole 81, thereby achieving the locking effect of the insertion rod 42 in the sleeve 41.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
