[0002] With the development of new energy technologies, energy storage devices have emerged.

[0003] At present, conventional energy storage structures generally refer to containerized energy storage. A large number of battery clusters are arranged in the container. When an individual battery cluster fails and catches fire, it will spread to other surrounding battery clusters, resulting in the damage of the energy storage devices in the entire container due to fire, causing huge losses. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an energy storage building, which reduces the risk of overall damage of battery clusters in the energy storage building and reduces losses.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] An energy storage building, comprising:

[0007] A foundation;

[0008] A surrounding wall, which is erected around the foundation and encloses an internal space;

[0009] A plurality of partition walls that crisscross each other. Each partition wall is erected on the foundation and is located within the surrounding wall. Each partition wall divides the internal space into a plurality of mutually isolated energy storage rooms, and at least part of the energy storage rooms are provided with battery clusters;

[0010] A blast relief roof, which is arranged on the surrounding wall and the partition walls. The blast relief roof covers each energy storage room, and the pressure resistance value of the blast relief roof is less than that of the partition walls and the surrounding wall;

[0011] A plurality of frame columns. The lower ends of each frame column are erected on the foundation, and the upper ends support the blast relief roof.

[0012] Optionally, each energy storage room is classified into a plurality of battery rooms and at least one equipment room. Each battery room is provided with a battery cluster, and the equipment room is provided with battery auxiliary equipment, and the battery auxiliary equipment is connected to each battery cluster.

[0013] Optionally, in the first direction, two rows of battery rooms and the equipment room located between the two rows of battery rooms are distributed in the internal space. Each row of battery rooms includes a plurality of battery rooms arranged in sequence along the second direction, and the first direction is perpendicular to the second direction.

[0014] Optionally, each row of the battery chambers includes two of the battery chambers.

[0015] Optionally, the explosion venting roof includes a light pressure relief roof or a lightweight and fragile roof.

[0016] Optionally, the explosion venting roof includes a roof truss, roof slabs, explosion venting bolts and explosion venting gaskets. The roof truss is arranged on the perimeter wall and the partition wall. The rod part of the explosion venting bolt sequentially passes through the explosion venting gasket, the roof slab, and is connected to the roof truss. The roof slab is clamped between the explosion venting gasket and the roof truss.

[0017] Optionally, both the partition wall and the perimeter wall include explosion-resistant walls, and the lower ends of the explosion-resistant walls are rigidly connected to the foundation.

[0018] Optionally, the explosion-resistant walls and the frame columns are arranged at intervals in the horizontal direction.

[0020] Optionally, the explosion-resistant walls and the frame columns are in abutment with each other in the horizontal direction.

[0021] Advantageous effects:

[0022] For the energy storage building provided by the present utility model, the perimeter wall forms the outer peripheral wall of the energy storage building, and the partition wall serves as the inner wall of the energy storage building. Together with the perimeter wall, multiple mutually isolated energy storage chambers are constructed, so that multiple battery clusters are independently stored in different energy storage chambers. Both the perimeter wall and the partition wall are building structures and concrete structures, and they have good fire isolation effects, enabling good isolation between different battery clusters and avoiding the direct damage of other battery clusters caused by the failure and fire of any one battery cluster, thereby facilitating loss reduction. The explosion venting roof serves as the roof of the energy storage chamber. On the one hand, it forms a closed energy storage chamber together with the perimeter wall and the partition wall to isolate different battery clusters. On the other hand, when a battery cluster in a certain energy storage chamber catches fire, the explosion venting roof opens prior to the side wall of the energy storage chamber, so that the energy storage chamber vents upward, avoiding the lateral pressure relief directly impacting other energy storage chambers and causing the failure and fire of other battery clusters, which is conducive to avoiding greater losses.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0037] As Figures 1-3 shown, this embodiment provides an energy storage building, which includes a foundation 100, a perimeter wall 102, partition walls 103, a blast relief roof 101 and frame columns 108.

[0038] The perimeter wall 102 is erected around the foundation 100 and encloses to form an internal space. A plurality of partition walls 103 crisscross, each partition wall 103 is erected on the foundation 100 and is located within the perimeter wall 102. Each partition wall 103 divides the internal space into a plurality of mutually isolated energy storage rooms, and at least part of the energy storage rooms are provided with battery clusters 105. The blast relief roof 101 is arranged on the perimeter wall 102 and the partition walls 103. The blast relief roof 101 covers each energy storage room, and the pressure resistance value of the blast relief roof 101 is less than that of the partition walls 103 and the perimeter wall 102. The lower ends of a plurality of frame columns 108 are erected on the foundation 100, and the upper ends support the blast relief roof 101 to ensure the overall structural reliability of the energy storage building.

[0039] The energy storage building provided in this embodiment has a perimeter wall 102 forming the outer peripheral wall of the energy storage building, and partition walls 103 as the inner walls within the energy storage building. The perimeter wall 102 and the partition walls 103 construct multiple mutually isolated energy storage rooms, so that multiple battery clusters 105 are independently stored in different energy storage rooms. Both the perimeter wall 102 and the partition walls 103 are building structures and concrete structures, with good fire isolation effects, enabling good isolation between different battery clusters 105 and preventing the failure and fire of any one battery cluster 105 from directly causing damage to other battery clusters 105, thus helping to reduce losses. The explosion vent roof 101 serves as the roof of the energy storage room. On the one hand, it forms a closed energy storage room together with the perimeter wall 102 and the partition walls 103 to isolate different battery clusters 105. On the other hand, the pressure resistance value of the explosion vent roof 101 is less than that of the side walls of the energy storage room. When a battery cluster 105 in a certain energy storage room catches fire, the explosion vent roof 101 opens prior to the side walls of the energy storage room, enabling the energy storage room to release pressure upward and avoiding lateral pressure release directly impacting other energy storage rooms and causing the failure and fire of other battery clusters 105, which is conducive to avoiding greater losses.

[0040] Optionally, each energy storage room is classified into multiple battery rooms 104 and at least one equipment room 106. Each battery room 104 is provided with a battery cluster 105, and the equipment room 106 is provided with battery auxiliary equipment 107, which is connected to each battery cluster 105. That is to say, the battery clusters 105 and the battery auxiliary equipment 107 are separated from each other and arranged in different energy storage rooms, which helps to prevent the direct damage of the battery auxiliary equipment 107 when a certain battery cluster 105 catches fire and fails. In this embodiment, the battery auxiliary equipment 107 can be a busbar cabinet, a liquid chiller, etc.

[0041] Optionally, in the first direction, there are two rows of battery rooms 104 distributed in the internal space, as well as an equipment room 106 located between the two rows of battery rooms 104. Each row of battery rooms 104 includes multiple battery rooms 104 arranged in sequence along the second direction, and the first direction and the second direction are perpendicular. The equipment room 106 is located between the two rows of battery rooms 104, enabling the battery auxiliary equipment 107 to be arranged between the two rows of battery clusters 105, facilitating the connection between the battery auxiliary equipment 107 and the two rows of battery clusters 105 on its both sides, and having a reasonable layout. Both the first direction and the second direction are in the horizontal plane. The first direction is the width direction of the energy storage building, and the second direction is the length direction of the energy storage building.

[0042] Optionally, each row of battery rooms 104 includes two battery rooms 104. That is to say, in the energy storage building, there are four battery rooms 104 and one equipment room 106. In the first direction, the equipment room 106 is centered between the two rows of battery rooms 104. The battery clusters 105 in the four battery rooms 104 share the battery auxiliary equipment 107 in one equipment room 106.

[0043] In this embodiment, asFigure 1 As shown, the energy storage building is generally rectangular in the plan view. The battery room 104 and the equipment room 106 are also rectangular. The four battery rooms 104 are of the same size. The sum of the lengths of two battery rooms 104 is equal to the length of the equipment room 106 and also equal to the length of the energy storage building. The sum of the widths of two battery rooms 104 plus the width of the equipment room 106 is equal to the width of the energy storage building.

[0044] Optionally, the explosion venting roof 101 includes a lightweight pressure relief roof or a lightweight fragile roof. The lightweight fragile roof is made of fragile materials. When a fire accident occurs inside the energy storage building, it not only has the function of pressure relief but also breaks into small pieces to reduce the impact on the outside. The pressure relief part of the lightweight pressure relief roof is made of lightweight materials. When an accident occurs inside the energy storage building, the lightweight pressure relief roof has the function of pressure relief, so that the main structure of the energy storage building is not damaged and the fire accident of the adjacent battery cluster 105 is avoided. In this embodiment, the explosion venting roof 101 adopts a lightweight pressure relief roof. Specifically, it can be a rock wool sandwich color steel plate roof.

[0045] As Figure 2 shown, in this embodiment, the explosion venting roof 101 further includes a roof beam 200. The upper end of the frame column 108 supports the roof beam 200, and the lightweight pressure relief roof or the lightweight fragile roof is supported by the roof beam 200.

[0046] As Figure 2 , Figure 4 and Figure 5 shown, optionally, the explosion venting roof 101 includes a roof truss 201, roof cover plates 202, explosion venting bolts 203 and explosion venting gaskets 204. The roof truss 201 is arranged on the perimeter wall 102 and the partition wall 103. The rod part of the explosion venting bolt 203 sequentially passes through the explosion venting gasket 204 and the roof cover plates 202 and is connected to the roof truss 201. The roof cover plates 202 are clamped between the explosion venting gasket 204 and the roof truss 201. The bending strength of the explosion venting gasket 204 determines the pressure resistance value of the explosion venting roof 101. The models and quantities of the explosion venting gasket 204 and the explosion venting bolts 203 are selected according to the explosion pressure value (pressure resistance value). As Figure 5 shown, under the action of the explosion pressure, the roof cover plates 202 drive the explosion venting gaskets 204 to deform. The explosion venting gaskets 204 release the limit on the roof cover plates 202, and the roof cover plates 202 open under the impact of the explosion air flow to achieve the purpose of explosion venting. In this embodiment, the explosion venting gasket 204 can be an aluminum alloy gasket. To prevent the roof cover plates 202 from flying around during explosion venting, the roof cover plates 202 can be connected to other structures of the energy storage building through traction cables.

[0047] Optionally, both the partition wall 103 and the perimeter wall 102 include explosion-resistant walls 300, and the lower ends of the explosion-resistant walls 300 are rigidly connected to the foundation 100. In this embodiment, both the partition wall 103 and the perimeter wall 102 are explosion-resistant walls 300, thus reliably isolating the battery clusters 105 inside as the side walls of the energy storage chamber. Specifically, the explosion-resistant walls 300 are constructed as reinforced concrete structures by masonry or casting and are rigidly connected to the foundation 100 to prevent the safety of other battery clusters 105 from being affected when a certain battery cluster 105 catches fire.

[0048] Optionally, the upper ends of the explosion-resistant walls 300 are hinged to the explosion venting roof 101. The hinge connection specifically means that the explosion-resistant walls 300 only bear the action of the explosion shock wave and do not bear the permanent and live loads of the explosion venting roof 101, improving the explosion resistance ability.

[0049] As Figure 6 shown, in one embodiment, the explosion-resistant walls 300 are in mutual abutment with the frame columns 108 in the horizontal direction. Since the upper and lower ends of the frame columns 108 are respectively connected to the explosion venting roof 101 and the foundation 100, therefore, the frame columns 108, the explosion venting roof 101 and the foundation 100 jointly form a constraint on the explosion-resistant walls 300, and the horizontal force on the explosion-resistant walls 300 is similar to that of a two-way slab. In this embodiment, the lateral stiffness of the frame columns 108 is very weak compared with that of the explosion venting roof 101 and the foundation 100, so a weak point of force occurs at the frame columns 108. As flexural members under compression, the frame columns 108 simultaneously bear the bending moment caused by the horizontal load transmitted from the explosion-resistant walls 300 and the axial force and bending moment caused by the permanent load and explosion load of the explosion venting roof 101. In the P-Δ effect, the frame columns 108 are prone to instability in extreme cases, and then the energy storage building collapses.

[0050] As Figure 7 shown, in another embodiment, the explosion-resistant walls 300 are arranged at intervals from the frame columns 108 in the horizontal direction. The horizontal force-bearing characteristic of the explosion-resistant walls 300 is that of a one-way slab. The force transmission path is: the shock wave acts on the explosion-resistant walls 300, the upper ends of the explosion-resistant walls 300 are transmitted to the explosion venting roof 101, and the lower ends are transmitted to the foundation 100; the explosion venting roof 101 is approximately infinitely rigid in its plane and transmits the force to the perimeter wall 102 and the partition wall 103, and the stiffness of the perimeter wall 102 and the partition wall 103 in their planes is very large, and the force is transmitted to the foundation 100. From the perspective of the failure mode, the weak points of this structure are at the connection nodes between the explosion-resistant walls 300 and the explosion venting roof 101 or the foundation 100 or at the vertical mid-span of the explosion-resistant walls 300. Even in the extreme case where the explosion-resistant walls 300 crack and deform into the plastic state, the frame columns 108, as the main vertical load-bearing members, do not directly bear the explosion shock, and the overall safety of the energy storage building structure is greatly improved compared with the previous structural form.

[0051] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
