Abstract

The present disclosure relates to an energy storage cabin. The energy storage cabin includes a cabin body and a cabin door. The cabin body has an opening and a first accommodation space. The cabin door is disposed at the opening of the cabin body in an openable and closable manner. The cabin door includes an inner door panel, an outer door panel, and a connecting member. The inner door panel is located at an inner side of the outer door panel in a stacking manner. A thermal insulation layer is provided between the inner door panel and the outer door panel. The connecting member penetrates the inner door panel to connect the inner door panel with the outer door panel. A heat insulation pad is sandwiched between the inner door panel and the outer door panel at a position where the connecting member penetrates the inner door panel.

First claim

What is claimed is:

1. An energy storage cabin, comprising:
a cabin body having at least one opening and a first accommodation space for accommodating an energy storage element, and
at least one cabin door each disposed at each of the at least one opening of the cabin body in an openable and closable manner, wherein:
each of the at least one cabin door comprises an inner door panel, an outer door panel, and a plurality of connecting members for connecting the inner door panel with the outer door panel;
the inner door panel is located at a side of the outer door panel facing towards the first accommodation space;
a thermal insulation layer is provided between the inner door panel and the outer door panel; and
a heat insulation pad is sandwiched between the inner door panel and the outer door panel at each of the plurality of connecting members,
wherein:
a fixation frame is provided at the side of the outer door panel facing towards the first accommodation space,
wherein the fixation frame is partially visible from the outside of the at least one cabin door;
each of the plurality of connecting members penetrates the inner door panel and the fixation frame in an arrangement direction from the inner door panel to the outer door panel to connect the inner door panel with the outer door panel;
the heat insulation pad has an annular closed structure in a shape corresponding to a shape of the fixation frame; and
the heat insulation pad is sandwiched between the fixation frame and an outer periphery of the inner door panel.

2. The energy storage cabin according to claim 1 , wherein:
the fixation frame comprises two first supporting members that are opposite to each other in a length direction of the cabin door and two second supporting members that are opposite to each other in a width direction of the cabin door, the two first supporting members and the two second supporting members being connected end-to-end in sequence to form the fixation frame corresponding to the outer periphery of the inner door panel;
each of the two first supporting members and the two second supporting members comprises a bottom wall and two side walls located between the bottom wall and the outer door panel;
a second accommodation space is defined by the two side walls, the bottom wall, and the outer door panel;
each of the plurality of connecting members is connected to the inner door panel and the bottom wall, at least part of the connecting member being accommodated in the second accommodation space; and
the heat insulation pad is sandwiched between the bottom wall and the outer periphery of the inner door panel.

3. The energy storage cabin according to claim 1 , wherein:
the fixation frame has a thickness of H 1 ;
a middle part of the inner door panel protrudes relative to the outer periphery of the inner door panel by a height of H 2 in a direction facing away from the outer door panel;
the heat insulation pad has a thickness of d; and
a distance H is formed between the middle part of the inner door panel and the outer door panel, where H=H 1 +H 2 +d.

4. The energy storage cabin according to claim 1 , wherein each of the plurality of connecting members is a fastener, the plurality of connecting members being evenly arranged at intervals in a peripheral direction of the fixation frame.

5. The energy storage cabin according to claim 1 , wherein a side surface of the inner door panel facing towards the outer door panel is provided with a plurality of reinforcing ribs arranged at intervals, each of the plurality of reinforcing ribs being located between the inner door panel and the outer door panel.

6. The energy storage cabin according to claim 5 , wherein:
each of the plurality of reinforcing ribs is inserted into the thermal insulation layer, a length direction of each of the plurality of reinforcing ribs being consistent with a width direction of each corresponding cabin door of the at least one cabin door; and/or
each of the plurality of reinforcing ribs comprises a connection portion and an extension portion that are connected to each other to form a structure with an L-shaped cross section, the connection portion being connected to the inner door panel, and the extension portion protruding towards the outer door panel.

7. The energy storage cabin according to claim 1 , wherein the thermal insulation layer is a rock wool board provided between the inner door panel and the outer door panel.

8. The energy storage cabin according to claim 1 , wherein the outer door panel is hinged to the cabin body, and the at least one cabin door is openable and closable at the at least one opening of the cabin body.

9. The energy storage cabin according to claim 1 , wherein:
the cabin body has a plurality of first accommodation spaces and a plurality of openings;
each of the plurality of first accommodation spaces corresponds to one of the plurality of openings;
each of the plurality of openings is provided with one cabin door; and
each first accommodation space of the plurality of first accommodation spaces has a temperature control system provided therein and configured to control a temperature in the first accommodation space.

10. The energy storage cabin according to claim 2 , wherein a side surface of the inner door panel facing towards the outer door panel is provided with a plurality of reinforcing ribs arranged at intervals, each of the plurality of reinforcing ribs being located between the inner door panel and the outer door panel.

11. The energy storage cabin according to claim 3 , wherein a side surface of the inner door panel facing towards the outer door panel is provided with a plurality of reinforcing ribs arranged at intervals, each of the plurality of reinforcing ribs being located between the inner door panel and the outer door panel.

12. The energy storage cabin according to claim 4 , wherein a side surface of the inner door panel facing towards the outer door panel is provided with a plurality of reinforcing ribs arranged at intervals, each of the plurality of reinforcing ribs being located between the inner door panel and the outer door panel.

13. The energy storage cabin according to claim 2 , wherein the thermal insulation layer is a rock wool board provided between the inner door panel and the outer door panel.

14. The energy storage cabin according to claim 3 , wherein the thermal insulation layer is a rock wool board provided between the inner door panel and the outer door panel.

15. The energy storage cabin according to claim 4 , wherein the thermal insulation layer is a rock wool board provided between the inner door panel and the outer door panel.
