The support platform for the energy storage cabin at the project site is basically designed as a flat surface. When the energy storage is supported on the support platform, rigid pads need to be added in the middle of the long side girders on both sides of the energy storage cabin to prevent the middle part of the cabin body from deforming during placement, affecting the normal use of the energy storage cabin.

[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. It should be noted that as long as there is no conflict, each embodiment in the present utility model and each feature in each embodiment can be combined with each other, and the technical solutions formed are all within the protection scope of the present utility model.

[0024] Those parts not described in the present utility model can be realized by adopting or referring to the existing technologies.

[0025] The energy storage cabin is a complete set of electrical equipment container, as Figure 1 and Figure 2 shown. In the prior art, there is a height difference of nearly 15 mm between the four corner fittings at the bottom of the energy storage cabin and the side girders on both sides. The energy storage cabin support platform at the project site is basically designed to be in the same plane. When the energy storage is supported on the support platform, rigid pads need to be added in the middle of the long side girders on both sides of the energy storage cabin to prevent the middle part of the cabin body from deforming during the placement process, affecting the normal use of the energy storage cabin.

[0026] To solve this technical problem, the present utility model proposes a new flat-bottom energy storage cabin, as Figure 3 and Figure 4 shown. The flat-drop water energy storage cabin of the present utility model includes a main frame, and the main frame includes side girders 1 and corner fittings 2 provided at both ends of the side girders 1 to form the top corners of the main frame. Among them, the bottom edge of the corner fitting 2 at the bottom of the main frame is flush with the bottom edge of the side girder 1 at the bottom.

[0027] By setting the bottom edge of the bottom corner fitting 2 to be flush with the bottom edge of the side girder 1, the strength of the energy storage cabin is ensured, the cabin body is not easily deformed, and the flat-bottom energy storage cabin can be adapted to match various forms of support platforms without adding shims.

[0028] In an optional embodiment, the corner fitting 2 and the side girder 1 are connected by welding. Further, the connection between the corner fitting 2 and the side girder 1 adopts full penetration groove welding. The connection between the corner fitting 2 and the side girder 1 is full penetration groove welded. Further increases the connection strength between the corner fitting 2 and the side girder 1.

[0029] As Figure 3 shown, in an optional embodiment, the side girder 1 includes a transverse top beam 11, a transverse bottom beam 12, a longitudinal top beam (not shown in the figure) and a longitudinal bottom beam (not shown in the figure). The transverse top beam 11 and the transverse bottom beam 12 are arranged in the left-right direction ( Figure 3 shown left-right direction), the longitudinal top beam and the longitudinal bottom beam are arranged in the front-back direction ( Figure 3 shown front-back direction). Two transverse top beams 11 and two longitudinal top beams form the four sides of the top surface of the main frame. Two transverse bottom beams 12 and two longitudinal bottom beams form the four sides of the bottom surface of the main frame. The top surface of the main frame and the bottom surface of the main frame are connected and supported by columns 13, and the columns 13 are arranged in the vertical direction.

[0030] Optionally, a plurality of vertical columns 13 are provided between the top surface and the bottom surface of the main frame. The plurality of vertical columns 13 are arranged along the length direction of the energy storage cabin (i.e., the extending direction of the cross beam). The vertical columns 13 located at both ends form the side surface of the energy storage cabin together with the longitudinal top beam and the longitudinal bottom beam.

[0031] In an alternative embodiment, the side edge of the corner fitting 2 is flush with the side edge of the vertical column 13. The flushness of the side edge of the corner fitting of the energy storage cabin with the edge of the vertical column improves the overall consistency of the side surface of the energy storage cabin and significantly optimizes the appearance of the energy storage cabin.

[0032] In an alternative embodiment, a plurality of cabins are arranged along the length direction of the flat-bottom energy storage cabin. Two vertical columns 13 are shared between adjacent cabins. Each cabin is provided with a pair of cabin doors 14. One end of the cabin door 14 of each cabin is respectively connected to the vertical column 13. Optionally, the connection manner between the cabin door 14 and the vertical column 13 is hinged or other detachable connections.

[0033] In an alternative embodiment, the flat-bottom energy storage cabin further includes a cover plate located at the cabin top, a bottom plate located at the cabin bottom, and side plates located at the sides, for closing the hollow of the main frame.

[0034] In an alternative embodiment, a ventilation assembly 15 is provided on one side of the cabin of the flat-bottom energy storage cabin to facilitate heat dissipation inside the energy storage cabin.

[0035] In an alternative embodiment, latch assemblies are respectively provided at the top and bottom of the cabin door 14. The cabin door 14 is closed by the latch assemblies. As Figure 3 shown, latch assemblies can be provided on each cabin door 14. The latch assembly includes a latch provided on the cabin door 14 and a socket provided at corresponding positions on the transverse top beam 11 and the transverse bottom beam 12.

[0036] Furthermore, a sealing strip can be provided between the cabin door and the main frame to prevent water from entering the connection part of the cabin door. Sealing strips are also provided between the cover plate and the transverse top beam and the transverse bottom beam to prevent water from entering the top.

[0037] In an alternative embodiment, the cover plate at the cabin top is wavy. Inside the cabin, multiple groups of reinforcing ribs (not shown in the figure) can be respectively provided on the cover plate at the cabin top and the bottom plate at the cabin bottom to further enhance the strength of the energy storage cabin and prevent it from deforming.
