Description

Technical Field

[0002] As the ecological environment continues to deteriorate, new methods of power generation need to be developed, and ocean power generation is one of the clean energy sources. It can be a thermoelectric conversion technology that uses the thermal gradient between warm surface seawater and deep cold seawater to generate electricity. It can also be a seawater wave power generation technology that converts wave force into compressed air to drive the generator to generate electricity. However, after the electricity is generated, it needs to be stored, and the energy storage system is to store it.

[0003] However, the energy storage system is usually equipped with battery modules, and the energy storage system is connected to the external power grid.

The second guide slope 52 is provided with an arc surface 53 that matches the inner wall of the third through hole 36.

[0030] At the same time, an escape opening 54 is formed between the locking end 47 and the hinge end 48 for escaping the first locking protrusion 41 or the second locking protrusion 28 .

[0031] The locking end 47 is provided with a fixing hole 55, and a counterweight 56 ​​is provided in the fixing hole 55. One end of the counterweight 56 ​​is larger, and the other end is smaller. The smaller end is close to the locking end 47, and the larger end is away from the locking end 47. When the unlocking end 39 enters the lifting hole 38, the counterweight 56 ​​can keep the locking end 47 from rotating downward under the influence of the counterweight 56, so that the unlocking end 39 is lifted. When the second guide slope 52 on the unlocking end 39 is as shown in FIG. Fig.10 When the tilted state shown changes to the horizontal state, the locking end 47 at this time can no longer limit the position of the first locking protrusion 41 or the second locking protrusion 28.

[0032] Example 3 Refer to the instruction manual Figures 10 to 14 As shown, the second docking assembly 8 includes a second pipe 57 connected to the PACK module 4 and a second spring 58 disposed on the second pipe 57.

The angle between the first vertical groove 68 and the second vertical groove 70 is 90°, that is, the arc angle of the arc groove 69 is also 90°. The height of the first vertical groove 68 is the height of only one first locking protrusion 41 plus the height of one locking area 62, while the height of the second vertical groove 70 is the height of multiple first locking protrusions 41 plus the height of multiple locking areas 62, and the second vertical groove 70 also extends to the second tube body 59.

[0036] The diameter of the limiting member 65 matches the diameter of the second through hole 15 , and the diameter of the limiting member 65 is smaller than the diameter of the carrying plate 60 .

[0037] When installing the limiting member 65, the limiting member 65 compresses the second spring 58, firstly placing the limiting protrusion 67 of the limiting member 65 in the first vertical groove 68, and then making the limiting protrusion 67 reach the connection between the first vertical groove 68 and the arc groove 69, and then rotating the limiting member 65 by 90 degrees, so as to keep the limiting protrusion 67 reaching the connection between the second vertical groove 70 and the arc groove 69. Under the elastic force of the second spring 58, the limiting member 65 pushes the limiting protrusion 67 to the position of limiting the limiting member 65 in the positioning opening 71.

[0038] A third docking hole 72 is formed in the middle of the first extension section 27 , and the extension tube 61 is docked with the third docking hole 72 .

[0039] When the first docking component 7 and the second docking component 8 are docked, the handle 37 is now in the vertical groove 35, so the first docking component 7 can be directly inserted into the second docking component 8 to complete the docking operation and realize the connection between the liquid cooling pipe 5 and the PACK module 4.

[0040] When disassembling, it is only necessary to push the handle 37 from the vertical groove 35 to the horizontal groove 34, so that the unlocking member 12 can be kept driving the lifting hole 38 to drive the unlocking end 39 of the locking member 16 to rotate upward. The locking end 47 no longer restricts the position of the second locking protrusion 28, and the first docking component 7 can be removed from the second docking component 8.
