Description

Technical Field

[0001] The present invention relates to the technical field of battery boxes, and in particular to a sodium ion battery box. Background Art

[0002] Sodium-ion batteries have certain advantages in terms of safety. First, the chemical properties of sodium-ion batteries are relatively stable. Sodium has a higher melting point than lithium and is more difficult to melt under extreme conditions, reducing the possibility of overheating due to internal short circuits. Sodium-ion batteries are not afraid of extrusion or puncture, making them very suitable as batteries for large energy storage power stations.

[0003] Battery energy storage stations are generally divided into two types: indoor and outdoor. For outdoor energy storage stations, a large box is generally set up, and the sodium ion module is installed in the box. In order to facilitate heat dissipation, heat dissipation holes are opened around the box. However, in extreme weather, such as summer rainstorms, if the drainage around the energy storage station is convenient, it may not be flooded. If the surrounding drainage system encounters blockage problems, the energy storage station will encounter the problem of flooding. Since the energy storage station box has heat dissipation holes around it, when flooded, rainwater will enter the box through the heat dissipation holes, causing the battery module components to be damaged by water, causing economic losses and personnel safety issues. Summary of the invention

[0004] The purpose of the present invention is to solve the problems pointed out in the background technology and to propose a sodium ion battery box.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A sodium ion battery case comprises a battery case, a sodium battery module is installed inside the battery case, the battery case comprises a vertical side panel, the battery case is only provided with a plurality of heat dissipation holes on the side panel, the heat dissipation holes located on the same horizontal plane are defined as a group of heat dissipation hole groups, each group of the heat dissipation hole groups is correspondingly provided with a buoyancy cover mechanism, and the buoyancy cover mechanism can seal the corresponding heat dissipation hole group before the liquid submerges the corresponding heat dissipation hole group.

[0007] The buoyancy sealing mechanism includes a cover plate located outside the side plate and a buoyancy pressure assembly. The cover plate is rotatably connected to the side plate via a first rotatable connector. In a natural state, the buoyancy pressure assembly can open the cover plate. In a flooded state, the buoyancy pressure assembly can press the cover plate to seal the corresponding heat dissipation hole group.

[0008] The first rotating connection member is located on the upper side of the corresponding heat dissipation hole group.

[0009] The buoyancy pressure assembly includes a support rod and a lever. The support rod is fixed to the side plate. The middle portion of the lever is rotatably connected to the support rod via a second rotating connection. The second rotating connection is located below the corresponding heat dissipation hole group. A floating member is installed at one end of the lever located below the second rotating connection. The end of the lever located above the second rotating connection is arranged close to the outer side of the cover plate.

[0010] One end of the lever located above the second rotating connecting member is connected to the outer side of the cover plate through a lifting member.

[0011] The pulling member is a chain or a draw rope.

[0012] The floating element is a floating ball.

[0013] The support rod is provided with an angle limiter, and the angle limiter can limit the maximum angle of the lever in the natural state.

[0014] A sealing gasket is fixedly connected to one side of the cover plate close to the side plate.

[0015] The sodium ion battery box proposed by the present invention has the beneficial effect that each heat dissipation hole group of the device is correspondingly installed with a buoyancy cover mechanism, and the corresponding heat dissipation hole group is sealed by the buoyancy cover mechanism before the liquid floods the corresponding heat dissipation hole group, so as to prevent the external water from entering the battery box through the heat dissipation hole group, and effectively protect the internal sodium battery module and other batteries and electronic equipment. Since each heat dissipation hole group of the device corresponds to a buoyancy cover mechanism, it can be ensured that the heat dissipation hole group that is flooded by water will be closed, and the heat dissipation hole group above it will still remain unobstructed, so that the sodium ion battery box can be used normally.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 2 A sodium ion battery case includes a battery case 1, a sodium battery module 2 is installed inside the battery case 1, the battery case 1 includes a vertical side panel 3, the battery case 1 is only provided with a plurality of heat dissipation holes on the side panel 3, and there are no heat dissipation holes or other holes at the top and the bottom, that is, when all the heat dissipation holes of the side panel are sealed, the entire battery case 1 is in a sealed state, as an implementation mode, the heat dissipation holes are horizontally arranged strip holes, and the heat dissipation holes located in the same horizontal plane are defined as a group of heat dissipation hole groups 4, each group of heat dissipation hole groups 4 is correspondingly installed with a buoyancy cover mechanism 5, and the buoyancy cover mechanism 5 can seal the corresponding heat dissipation hole group 4 before the liquid submerges the corresponding heat dissipation hole group 4.

[0021] Each heat dissipation hole group 4 of the device is correspondingly installed with a buoyancy cover mechanism 5. Before the liquid floods the corresponding heat dissipation hole group 4, the corresponding heat dissipation hole group 4 is sealed by the buoyancy cover mechanism 5 to prevent external water from entering the battery box 1 through the heat dissipation hole group 4, effectively protecting the internal sodium battery module 2 and other batteries and electronic equipment. Since each heat dissipation hole group 4 of the device corresponds to a buoyancy cover mechanism 5, it can be ensured that the heat dissipation hole group 4 that is flooded by water will be closed, and the heat dissipation hole group 4 above it will still remain unobstructed, so that the sodium ion battery box can be used normally.

[0022] The buoyancy sealing mechanism 5 includes a cover plate 7 located on the outside of the side plate 3 and a buoyancy pressure assembly. The cover plate 7 is rotatably connected to the side plate 3 via a first rotatable connector 9. In a natural state, the buoyancy pressure assembly can open the cover plate 7. In a flooded state, the buoyancy pressure assembly can press the cover plate 7 to seal the corresponding heat dissipation hole group 4.

[0023] refer to Figure 2 The cover plate 7 is rotatably connected to the side plate 3 via the first rotatable connector 9. When flooded, the buoyancy pressure component can press the cover plate 7 to rotate the cover plate around the first rotatable connector 9 to achieve sealing of the corresponding heat dissipation hole group 4.

[0024] Preferably, the first rotating connection member 9 is located on the upper side of the corresponding heat dissipation hole group 4, so that it can serve as a rain shelter.

[0025] As an embodiment, the buoyancy pressure assembly includes a support rod 6 and a lever 12. The support rod 6 is fixed to the side plate 3. The middle part of the lever 12 is rotatably connected to the support rod 6 through a second rotating connection member 14. The second rotating connection member 14 is located below the corresponding heat dissipation hole group 4. A floating member 13 is installed at one end of the lever 12 located below the second rotating connection member 14, and the end of the lever 12 located above the second rotating connection member 14 is arranged close to the outer side of the cover plate 7.

[0026] refer to Figure 2As the water level rises, the buoyancy of the liquid drives the floating member 13 to move upward. Under the action of the second rotating connecting member 14, the top end of the lever 12 squeezes the cover plate 7 to move toward the position of the heat dissipation hole group 4. Before the water level reaches the position of the heat dissipation hole group 4, the lever 12 squeezes the cover plate 7 to close the corresponding second rotating connecting member 14.

[0027] One end of the lever 12 located above the second rotating connecting member 14 is connected to the outer side of the cover plate 7 through the lifting member 10. Figure 2 When there is no flooding, the floating member 13 drives the lever 12 to rotate counterclockwise under the action of gravity, and pulls the cover plate 7 to open the heat dissipation hole group 4 through the pulling member 10; for example, the pulling member 10 is a chain or a pull rope; the floating member 13 is a float.

[0028] The device does not need to rely on any electronic components at all. The heat dissipation hole group 4 is automatically closed when flooded, and the heat dissipation hole group 4 is automatically opened when there is no flooding.

[0029] The support rod 6 is provided with a rotation angle limiter 11, which can limit the maximum rotation angle of the lever 12 in a natural state, so as to prevent the lever 12 from exceeding the turning limit and abutting against the cover plate 7 when flooded.

[0030] A sealing gasket 8 is fixedly connected to one side of the cover plate 7 close to the side plate 3 , and the sealing performance is improved by the sealing gasket 8 .
