[0001] The utility model relates to the technical field of prefabricated cabins, in particular to an energy storage prefabricated cabin. Background Art

[0002] In the prefabricated cabin of the energy storage system, liquid cooling equipment and its pipelines, electrical cabinets, fire protection equipment, and multiple battery packs are placed. Currently, with the continuous increase in the overall capacitance demand in the energy storage system, more batteries are required to be arranged in the prefabricated cabin of the energy storage system. Therefore, it is necessary to further improve the protection of the prefabricated cabin.

[0003] Currently, the prefabricated cabin door generally uses a gasket as the main sealing means. However, the durability of the gasket is limited, and it is prone to aging, wear, or deformation over time, resulting in a gradual decline in the sealing performance and affecting the overall sealing effect of the cabin door. This phenomenon not only increases the risk of water ingress into the cabin but also may damage the equipment inside the cabin, exacerbate the corrosion of the equipment inside the prefabricated cabin, and affect the stable operation of the energy storage system. Summary of the Utility Model

[0004] In view of this, the utility model provides an energy storage prefabricated cabin to solve the problems that the gasket is prone to aging, wear, or deformation, affecting the overall sealing effect of the cabin door, which not only increases the risk of water ingress into the cabin but also may damage the equipment inside the cabin, exacerbate the corrosion of the equipment inside the prefabricated cabin, and affect the stable operation of the energy storage system.

[0005] The utility model provides an energy storage prefabricated cabin, which includes a cabin body, a cabin door, and a bottom waterproof structure; a door frame is provided on one side of the cabin body; one side of the cabin door is hinged to the door frame; the bottom waterproof structure is located inside the cabin body, protrudes along the first direction on the bottom beam of the door frame, and is arranged at an interval from the cabin door along the second direction; the first direction is the height direction of the cabin body, and the second direction is the width direction of the cabin body.

[0006] Beneficial Effects: Since the bottom waterproof structure and the cabin door are arranged in sequence along the second direction, and the bottom waterproof structure is arranged inside the cabin body, when the sealing performance of the door gasket deteriorates and the problem of sealing failure occurs, external rainwater flows down along the prefabricated cabin door to the bottom beam of the prefabricated cabin, and then is intercepted by the bottom waterproof structure, reducing the possibility of external rainwater entering the cabin body, improving the environmental quality inside the cabin, and enhancing the safety of the equipment inside the cabin.

[0007] In an optional embodiment, a sealing structure is further included. In the first direction, there is a gap between the bottom beam of the door frame and the cabin door, and the sealing structure is arranged in the gap.

[0008] Beneficial effects: Since there is a gap between the bottom beam of the door frame and the hatch door in the first direction, it is convenient to open and close the hatch door; by arranging a sealing structure in the gap, the sealing performance of the energy storage prefabricated cabin is further improved.

[0009] In an alternative embodiment, in the first direction, the height of the bottom waterproof structure is greater than the thickness of the gap.

[0010] Beneficial effects: Since in the first direction, the height of the bottom waterproof structure is greater than the thickness of the gap between the bottom beam of the door frame and the hatch door, the bottom waterproof structure can limit the angle of the hatch door rotating inward to the interior of the cabin, prevent the hatch door from rotating excessively into the interior of the cabin, avoid the hatch door from denting into the interior of the cabin, enhance the sealing performance of the sealing structure, and facilitate the opening and closing of the hatch door.

[0011] In an alternative embodiment, it further includes a limit bracket, one end of the limit bracket is connected to the inner side of the hatch door, and when the hatch door is opened, the other end of the limit bracket is connected to the bottom of the door frame.

[0012] Beneficial effects: When the hatch door is opened, since one end of the limit bracket is connected to the inner side of the hatch door and the other end is connected to the bottom of the door frame, it can limit the opening angle of the hatch door. When the hatch door is affected by external thrusts such as wind thrust or human thrust, it can prevent the hatch door from rotating away from the cabin and hitting people or other objects around, and can also prevent the hatch door from rotating towards the cabin and hitting the cabin or other equipment inside the cabin, avoiding unnecessary accidents and damage to the energy storage prefabricated cabin.

[0013] In an alternative embodiment, one end of the limit bracket is a rotating end, and the rotating end is rotatably connected to the inner side of the hatch door; the other end of the limit bracket is a mobile end, and there are a plurality of grooves provided on the bottom waterproof structure, and the plurality of grooves are arranged at intervals in the third direction; when the hatch door is opened, the mobile end is adapted to be placed in different grooves, and the third direction is the length direction of the cabin.

[0014] Beneficial effects: By arranging the grooves, the opening angle of the hatch door can be limited; since there are a plurality of grooves, and the rotating end is rotatably connected to the inner side of the hatch door, the mobile end of the limit bracket can be placed in different grooves, so the opening angles of the hatch door can be limited in multiple ways, and the hatch door can be opened to different angles according to actual usage requirements, improving the applicability of the limit structure.

[0015] In an alternative embodiment, a limiting structure is further included. The limiting structure is located below the hatch door and is arranged on the inner side of the hatch door. The limiting structure includes a bracket, which is fixedly connected to the hatch door, has a connection hole at one end and a placement groove at the other end. The rotating end is rotatably connected to the connection hole. When the hatch door is closed, the moving end can be moved out of the groove and placed in the placement groove.

[0016] Advantageous effects: Through the arrangement of the connection hole on the bracket, the rotatable connection between the limiting bracket and the hatch door is realized. And by arranging a placement groove on the bracket, when the hatch door needs to be closed, the moving end of the limiting bracket can be taken out from the groove on the bottom waterproof structure, that is, the connection between the moving end and the bottom of the door frame is disconnected, and the moving end is placed in the placement groove. At this time, the entire limiting bracket is located on the limiting structure, thus avoiding the obstruction of the limiting bracket to the closing path of the hatch door and ensuring that the hatch door can be closed smoothly and without obstruction. And by arranging the placement groove, the moving end of the limiting bracket can also be limited, and during the opening and closing rotation process of the prefabricated hatch door, the problem that the moving end of the limiting bracket falls off the bracket, resulting in the prefabricated hatch door being unable to be closed, can be avoided.

[0017] In an alternative embodiment, the limiting structure further includes a fixing member, which is located below the connection hole, and the rotating end passes through the connection hole and is connected to the fixing member.

[0018] Advantageous effects: Through the arrangement of the fixing member, a flexible and stable rotatable connection between the limiting bracket and the hatch door can be realized, which not only ensures the smoothness of the limiting bracket during rotation, but also effectively prevents the limiting bracket from falling off the bracket, greatly enhancing the stability and safety of the connection between the limiting bracket and the bracket, and improving the reliability of the overall structure.

[0019] In an alternative embodiment, in the first direction, the limiting structure is located above the bottom waterproof structure.

[0020] Advantageous effects: By locating the limiting structure above the bottom waterproof structure in the first direction, when the hatch door is closed, the problem of interference between the limiting structure and the bottom waterproof structure is avoided. And when the hatch door is closed, from the second direction, the limiting structure and the bottom waterproof structure are arranged compactly, occupying less space, improving the space utilization rate of the energy storage prefabrication, and realizing the dual optimization of space utilization and functionality.

[0021] In an alternative embodiment, a top water blocking structure is further included. The top water blocking structure is located at the top of the cabin body, is arranged on the side of the cabin body provided with a door frame, and protrudes from the hatch door along the second direction.

[0022] Beneficial effects: By providing the top water blocking structure, it is possible to prevent external rainwater from directly flowing onto the sealing surfaces of the hatch door and the door frame, reducing the risk of rainwater entering the cabin from the sealing surfaces of the hatch door and the door frame.

[0023] In an alternative embodiment, the angle between the top water blocking structure and the side of the cabin body where the door frame is provided is less than or equal to ninety degrees.

[0024] Beneficial effects: By setting the angle between the top water blocking structure and the side of the cabin body where the door frame is provided to be less than or equal to ninety degrees, it is ensured that rainwater can directly flow out from the top water blocking structure, effectively preventing the retention of accumulated water. This not only improves the drainage efficiency of the top water blocking structure but also avoids erosion or leakage problems that may be caused by accumulated water, further enhancing the overall waterproof performance and durability of the top water blocking structure.

Detailed implementation manners

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] The following combines Figures 1 to 12 , to describe the embodiments of the present invention.

[0042] According to an embodiment of the present invention, an energy storage prefabricated cabin is provided, including a cabin body 1, a cabin door 2, and a bottom waterproof structure 3; a door frame 11 is provided on one side of the cabin body 1; one side of the cabin door 2 is hinged to the door frame 11; the bottom waterproof structure 3 is located inside the cabin body 1, protrudes along a first direction on the bottom beam 111 of the door frame 11, and is spaced from the cabin door 2 along a second direction; the first direction is the height direction of the cabin body 1, and the second direction is the width direction of the cabin body 1.

[0043] Since the hatches 2 are arranged at intervals in the second direction due to the bottom waterproof structure 3, and the bottom waterproof structure 3 is arranged inside the cabin body 1, when the sealing performance of the door gasket deteriorates and a sealing failure problem occurs, external rainwater flows down along the prefabricated hatch 2 to the prefabricated cabin bottom beam 111, and then is intercepted by the bottom waterproof structure 3, reducing the possibility of external rainwater entering the cabin body 1, improving the quality of the cabin environment, and enhancing the safety of the equipment inside the cabin.

[0044] Specifically, a battery compartment is designed inside the energy storage prefabricated cabin. The battery compartment is used to arrange battery clusters integrated with multiple batteries. A partial schematic layout diagram of the energy storage system of the prefabricated cabin is as Figure 1 shown. Multiple batteries are stacked in sequence in the first direction and arranged along the length direction of the cabin body 1.

[0045] Specifically, as Figures 5 to 8 shown, it is a cross-sectional schematic diagram of the bottom waterproof structure 3 in the second direction. The cross-section of the bottom waterproof structure 3 includes but is not limited to a circular shape, an L shape, a rectangular shape, a C shape, etc.

[0046] In one embodiment, a sealing structure 4 is further included. In the first direction, there is a gap between the bottom beam 111 of the door frame 11 and the hatch 2, and the sealing structure 4 is arranged in this gap.

[0047] Since there is a gap between the bottom beam 111 of the door frame 11 and the hatch 2 in the first direction, it is convenient to open and close the hatch 2; by arranging the sealing structure 4 in the gap, the sealing performance of the energy storage prefabricated cabin is further improved.

[0048] In one embodiment, in the first direction, the height of the bottom waterproof structure 3 is greater than the thickness of the gap.

[0049] Since in the first direction, the height of the bottom waterproof structure 3 is greater than the thickness of the gap between the bottom beam 111 of the door frame 11 and the hatch 2, the bottom waterproof structure 3 can also limit the angle of the hatch 2 rotating inward and closing towards the interior of the cabin body 1, preventing the hatch 2 from rotating excessively into the interior of the cabin body 1, avoiding the depression of the hatch 2 towards the interior of the cabin body 1, enhancing the sealing performance of the sealing structure 4, and facilitating the opening and closing of the hatch 2.

[0050] Specifically, in the first direction, the height of the bottom waterproof structure 3 is greater than the thickness of the gap, and the height of the bottom waterproof structure 3 is less than or equal to ten times the thickness of the gap.

[0051] In one embodiment, a limit bracket 5 is further included. One end of the limit bracket 5 is connected to the inner side of the hatch 2, and when the hatch 2 is opened, the other end of the limit bracket 5 is connected to the bottom of the door frame 11.

[0052] When the hatch 2 is opened, since one end of the limit bracket 5 is connected to the inner side of the hatch 2 and the other end is connected to the bottom of the door frame 11, the opening angle of the hatch 2 can be limited. When the hatch 2 is affected by external thrusts such as wind thrust or human thrust, it can prevent the hatch 2 from rotating away from the cabin 1 and colliding with surrounding people or other objects, and can also prevent the hatch 2 from rotating towards the cabin 1 and colliding with the cabin 1 or other equipment inside the cabin, avoiding unnecessary accidents and damage to the energy storage prefabricated cabin.

[0053] In one embodiment, one end of the limit bracket 5 is a rotating end 51, and the rotating end 51 is rotatably connected to the inner side of the hatch 2; the other end of the limit bracket 5 is a movable end 52, and a plurality of grooves 31 are provided on the bottom waterproof structure 3, and the plurality of grooves 31 are arranged at intervals in the third direction. When the hatch 2 is opened, the movable end 52 is adapted to be placed in different grooves 31, and the third direction is the length direction of the cabin 1.

[0054] By providing the grooves 31, the opening angle of the hatch 2 can be limited; since there are a plurality of grooves 31 and the rotating end 51 is rotatably connected to the inner side of the hatch 2, the movable end 52 of the limit bracket 5 can be placed in different grooves 31, so that the opening angles of the hatch 2 can be limited in multiple ways, and the hatch 2 can be opened to different angles according to actual usage requirements, improving the applicability of the limit structure 6.

[0055] Specifically, the limit bracket 5 includes a body 53, a rotating end 51 and a movable end 52. The rotating end 51 and the movable end 52 are respectively located at both ends of the body 53, and an included angle is provided between the rotating end 51 and the movable end 52 and the body 53 respectively, and the extending directions of the rotating end 51 and the movable end 52 are the same.

[0056] In a specific implementation manner, the groove 31 can also be a through hole.

[0057] In an alternative implementation manner, it can also be that a plurality of connecting grooves are provided on the bottom beam 111 of the door frame 11. The connecting grooves are located between the bottom waterproof structure 3 and the hatch 2, and the plurality of connecting grooves are arranged at intervals in the third direction, and the movable end 52 is adapted to be placed in different connecting grooves.

[0058] In an alternative embodiment, it is also possible that a plurality of limiting grooves 112 are provided at the bottom of the door frame 11. The limiting grooves 112 are arranged outside the cabin body 1, and the plurality of limiting grooves 112 are arranged at intervals in sequence along the third direction. The mobile end 52 is adapted to be placed in different limiting grooves 112. Specifically, the limiting groove 112 is formed by enclosing the side surface of the cabin body 1 with a bending member 113. Specifically, the bending member 113 can be bent and made of a structure such as a steel bar.

[0059] Specifically, when the cross-section of the bottom waterproof structure 3 is a rectangular or C-shaped structure, etc., the mobile end 52 can be limited by the groove 31.

[0060] Specifically, such as Figure 9 or Figure 10 As shown, when the cross-section of the bottom waterproof structure 3 is a circular or L-shaped structure, etc., the mobile end 52 can be limited by the connecting groove or the limiting groove 112.

[0061] In one embodiment, a limiting structure 6 is further included. The limiting structure 6 is located below the cabin door 2 and is arranged inside the cabin door 2. The limiting structure 6 includes a bracket 61. The bracket 61 is fixedly connected to the cabin door 2, with a connecting hole 611 at one end and a placement groove 612 at the other end. The rotating end 51 is rotatably connected to the connecting hole 611. When the cabin door 2 is closed, the mobile end 52 of the limiting bracket 5 can be moved out of the groove 31 and placed in the placement groove 612.

[0062] Through the setting of the connecting hole 611 on the bracket 61, the rotatable connection between the limiting bracket 5 and the cabin door 2 is realized. And by providing the placement groove 612 on the bracket 61, when the cabin door 2 needs to be closed, the mobile end 52 of the limiting bracket 5 can be taken out of the groove 31 on the bottom waterproof structure 3, that is, the connection between the mobile end 52 and the bottom of the door frame 11 is disconnected, and the mobile end 52 is placed in the placement groove 612. At this time, the entire limiting bracket 5 is located on the limiting structure 6, thereby avoiding the obstruction of the limiting bracket 5 to the closing path of the cabin door 2 and ensuring that the cabin door 2 can be closed smoothly and without obstruction. And by providing the placement groove 612, the mobile end 52 of the limiting bracket 5 can also be limited, and during the opening and closing rotation process of the prefabricated cabin door 2, the problem that the mobile end 52 of the limiting bracket 5 falls off the bracket 61, resulting in the prefabricated cabin door 2 being unable to be closed, can be avoided.

[0063] In a specific embodiment, first place the mobile end 52 of the limiting bracket 5 in the placement groove 612, and then close the cabin door 2.

[0064] Specifically, the main body 53 of the limiting bracket 5 is arranged above the limiting structure 6.

[0065] In one embodiment, the limiting structure 6 further includes a fixing member 62, the fixing member 62 is located below the connecting hole 611, and the rotating end 51 passes through the connecting hole 611 and is connected to the fixing member 62.

[0066] By providing the fixing member 62, a flexible and stable rotatable connection between the limiting bracket 5 and the hatch door 2 can be achieved. This not only ensures the smoothness of the limiting bracket 5 during rotation but also effectively prevents the limiting bracket 5 from falling off the bracket 61, greatly enhancing the stability and safety of the connection between the limiting bracket 5 and the bracket 61 and improving the reliability of the overall structure.

[0067] Specifically, the fixing member 62 can be an annular member that is sleeved on the outer periphery of the rotating end 51 and fixedly connected to the rotating end 51. When the fixing member 62 is an annular member, the outer diameter of the annular member is greater than the diameter of the connecting hole 611; and the fixing member 62 and the rotating end 51 can be connected by a threaded connection or by welding.

[0068] Specifically, the fixing member 62 can be a fixing block, and the fixing block can be fixed to one side of the rotating end 51 by welding or other means, and the diameter of the largest circumscribed circle of the overall structure formed by the fixing block and the rotating end 51 is greater than the diameter of the connecting hole 611.

[0069] Specifically, since the fixing member 62 is fixedly connected to the rotating end 51, the fixing member 62 and the bracket 61 are spaced apart, which facilitates the removal of the mobile end 52 of the limiting bracket 5 from the placement groove 612 or placing it in different grooves 31.

[0070] In one embodiment, in the first direction, the limiting structure 6 is located above the bottom waterproof structure 3.

[0071] By having the limiting structure 6 located above the bottom waterproof structure 3 in the first direction, when the hatch door 2 is closed, the problem of interference between the limiting structure 6 and the bottom waterproof structure 3 is avoided; and when the hatch door 2 is closed, from the second direction, the limiting structure 6 and the bottom waterproof structure 3 are arranged compactly, occupying less space, improving the space utilization rate of the energy storage prefabrication, and achieving a dual optimization of space utilization and functionality.

[0072] In one embodiment, it further includes a top water blocking structure 7, the top water blocking structure 7 is located at the top of the cabin body 1, is provided on one side of the cabin body 1 where the door frame 11 is provided, and protrudes from the hatch door 2 along the second direction.

[0073] By providing the top water blocking structure 7, it is possible to prevent external rainwater from directly flowing on the sealing surfaces of the hatch door 2 and the door frame 11, reducing the risk of rainwater entering the cabin from the sealing surfaces of the hatch door 2 and the door frame 11.

[0074] In one embodiment, the angle between the top water retaining structure 7 and the side of the cabin body 1 where the door frame 11 is provided is less than or equal to ninety degrees.

[0075] By setting the angle between the top water retaining structure 7 and the side of the cabin body 1 where the door frame 11 is provided to be less than or equal to ninety degrees, it is ensured that rainwater can directly flow out from the top water retaining structure 7, effectively preventing the retention of accumulated water. This not only improves the drainage efficiency of the top water retaining structure 7 but also avoids erosion or leakage problems that may be caused by accumulated water, further enhancing the overall waterproof performance and durability of the top water retaining structure 7.

[0076] In a specific implementation manner, the top water retaining structure 7 is arranged on the top beam of the cabin body 1. The top water retaining structure 7 extends in the third direction and can be connected to one of the top corner fittings 12 of the cabin body 1. In the first direction, the top water retaining structure 7 is located above the cabin door 2 and the door lock structure 8; in the second direction, the top water retaining structure 7 can at least cover part of the prefabricated cabin door 2 and the door lock structure 8; as Figure 12 shown, the top water retaining structure 7 is wider than the prefabricated cabin door 2 and the door lock structure 8, that is, the top water retaining structure 7 completely covers the prefabricated cabin door 2 and the door lock structure 8.

[0077] Specifically, the top corner fitting 12 is a hanging point for hoisting at the four corners of the top of the energy storage prefabricated cabin.

[0078] Specifically, the top water retaining structure 7 is flanged on the side close to the cabin body 1, which can improve the strength of the top water retaining structure 7.

[0079] Specifically, the top water retaining structure 7 can be a flashing board.
