Description

Technical Field

[0001] The present invention relates to power generation and energy storage technology, and in particular to a liquid-cooled energy storage system for ocean power generation. Background Art

[0002] As the ecological environment continues to deteriorate, new methods of power generation are needed. Ocean power generation is one such clean energy source. It can be a thermoelectric conversion technology that utilizes the thermal gradient between warm surface water and cold deep water to generate electricity. Alternatively, it can be a wave power generation technology that converts wave force into compressed air to drive a generator. However, once electricity is generated, it needs to be stored, and energy storage systems are used to store this electricity.

[0003] However, energy storage systems typically contain battery modules and are connected to the external power grid. During periods of low electricity demand, the energy storage cabinet absorbs electricity and converts it into chemical energy. During peak demand, the cabinet feeds the energy into the grid or uses it as a power source. The battery modules within the energy storage cabinet generate significant heat during charging and discharging, raising the cabinet's temperature. Excessively high temperatures can shorten the battery's lifespan and increase the risk of spontaneous combustion.

[0004] In the current structure, using liquid cooling to cool the interior of the energy storage cabinet requires disassembly and assembly of the battery modules, as well as regular maintenance and inspection of the modules. This requires disconnecting the modules from the cooling pipes. If a clamp-type structure were used, long-term disassembly and assembly could shorten the lifespan, leading to coolant leaks. Furthermore, disassembly and assembly cannot be completed quickly, impacting the efficiency of maintenance and assembly. Summary of the Invention

The upper end of the first pipe 9 is connected to the branch pipe 6 via a flexible pipe. The housing 10 is disposed outside the first pipe 9, and the interior of the housing 10 is hollowed out to form a mounting area 13. The docking seat 11 is disposed within the housing 10. A first through-hole 14 and a second through-hole 15 are formed in the middle of the docking seat 11. The first through-hole 14 and the second through-hole 15 are connected, and the second through-hole 15 is located at the lower end of the first through-hole 14. The lower end of the first pipe 9 is located within the first through-hole 14. The diameter of the first through-hole 14 is smaller than that of the second through-hole 15. A symmetrically arranged locking member 16 is provided in the middle of the docking seat 11. The locking member 16 is hinged to the interior of the docking seat 11 via a hinge rod 17. The unlocking member 12 is sleeved on the docking seat 11 and is located within the mounting area 13. The unlocking member 12 is provided with a first spring 18.

[0049] The first pipe 9 consists of a first tube body 19 and a fixing plate 20. A first docking hole 21 is formed in the center of the first tube body 19. The fixing plate 20 is connected to the housing 10 via bolts 22. The fixing plate 20 is provided with a countersunk hole 23 and a first retaining hole 24. The fixing portion 25 of the housing 10 is provided with a second retaining hole 26. The docking seat is provided with a third retaining hole 74. Bolts 22 are placed in the countersunk hole 23, the first retaining hole 24, the second retaining hole 26, and the third retaining hole 74, thereby mounting the housing 10 and the docking seat 11 on the first pipe 9 and moving together with the first pipe 9.

[0050] An extension section 27 is provided at the lower end of the first tube 19. A second locking protrusion 28 is provided at the lower end of the extension section 27. The second locking protrusion 28 is provided with a second guiding inclined surface 29 and a second blocking surface 30. A movable area 31 is formed between the extension section 27 and the second locking protrusion 28. The movable area 31 is used to keep the locking member 16 in the locked state at all times, facilitating a quick docking operation when the first docking assembly 7 and the second docking assembly 8 are docked.

[0051] The upper end of the housing 10 is provided with a fixing portion 25, and the middle of the fixing portion 25 is provided with a through hole 32 that cooperates with the first pipe 9. The housing 10 is provided with a movable groove 33, which is composed of a horizontal groove 34 and a vertical groove 35.

[0052] A third through-hole 36 is formed in the center of the unlocking member 12. A handle 37 is provided on the unlocking member 12, which engages with the movable slot 33. The width of the handle 37 matches the width of the vertical slot 35, and the height of the handle 37 matches the height of the transverse slot 34. The handle 37 can be moved within the movable slot 33, thereby adjusting the angle and height of the unlocking member 12. The unlocking member 12 also has a lifting hole 38, which engages with the locking member 16. Located at the lower end of the handle 37, the lifting hole 38 is used to lift the unlocking end 39, thereby rotating the locking member 16.

[0053] When the handle 37 is in the vertical slot 35, the first spring 18 is in a natural state or a slightly compressed state, keeping the lower end of the unlocking member 12 on the first bearing surface 40. When the handle 37 is lifted upward, the handle 37 drives the unlocking member 12 to move upward, compressing the first spring 18 at the same time. When the handle 37 reaches the connection between the vertical slot 35 and the transverse slot 34, the handle 37 can be rotated so that the handle 37 moves from the vertical slot 35 to the transverse slot 34. After the handle 37 is released, the first spring 18 can be restricted under the load of the transverse slot 34 to push the unlocking member 12 back to its original position, thereby keeping the lifting hole 38 on the unlocking member 12 to drive the locking member 16 to rotate, and keeping the locking member 16 from continuing to restrict the first locking protrusion 41, the first docking assembly 7 and the second docking assembly 8 can be separated.

[0054] The docking station 11 is composed of a first column 42, a second column 43, and a third column 44. The junction of the first column 42 and the second column 43 forms a first bearing surface 40, and the junction of the second column 43 and the third column 44 forms a second bearing surface 45. The unlocking member 12 is placed on the first bearing surface 40, and the housing 10 is placed on the second bearing surface 45. A symmetrical through-slot 46 is provided in the center of the first column 42, communicating with the first through-hole 14. The locking member 16 is mounted in the through-slot 46 via a hinge rod 17. The docking station 11 is provided with a second hinge hole 73 that mates with the hinge rod 17.

[0055] The locking member 16 comprises a locking end 47, an unlocking end 39, and a hinged end 48. A first hinge hole 49 is defined in the center of the hinged end 48, and the hinged rod 17 is disposed within the first hinge hole 49. The locking end 47 is provided with a locking flat surface 50 and a first guide slope 51. The unlocking end 39 is provided with a second guide slope 52. The second guide slope 52 is provided with an arcuate surface 53 that mates with the inner wall of the third through-hole 36.

[0056] 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 .

[0057] 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 closer to the locking end 47, while the larger end is farther 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, thereby lifting the unlocking end 39. When the second guide slope 52 on the unlocking end 39 is formed by the following Figure 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.

[0058] Example 3

[0059] 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 second pipe 57 is provided with multiple first locking protrusions 41 that engage with the locking member 16. The upper end of the second spring 58 engages with the second through-hole 15. The lower end of the second pipe 57 can be provided with an elbow to facilitate docking with the PACK module 4.

[0060] The second pipe 57 is composed of a second tube body 59 and a carrier plate 60. The second tube body 59 is provided with an extension tube 61 and a plurality of first locking protrusions 41. A locking area 62 is formed between the first locking protrusions 41. The first locking protrusions 41 are provided with a first guiding inclined surface 63 and a first blocking surface 64. The first blocking surface 64 cooperates with the locking plane 50.

[0061] A limiting member 65 is sleeved on the second tube body 59. The second spring 58 is placed on the supporting plate 60, with the upper end in contact with the limiting member 65. A limiting hole 66 is formed in the middle of the limiting member 65, and symmetrical limiting protrusions 67 are provided in the limiting hole 66.

[0062] The second tube 59 is provided with a first vertical slot 68, an arcuate slot 69, and a second vertical slot 70, which are arranged rotationally symmetrically. The first vertical slot 68 and the second vertical slot 70 are connected by the arcuate slot 69, and a positioning opening 71 is formed in the second vertical slot 70. The angle between the first vertical slot 68 and the second vertical slot 70 is 90°, that is, the arcuate angle of the arcuate slot 69 is also 90°. The height of the first vertical slot 68 is the height of one first locking protrusion 41 plus the height of one locking area 62, while the height of the second vertical slot 70 is the height of multiple first locking protrusions 41 plus the height of multiple locking areas 62. The second vertical slot 70 also extends into the second tube 59.

[0063] 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 carrier plate 60 .

[0064] When installing the limiting member 65, the limiting member 65 compresses the second spring 58, first placing the limiting protrusion 67 of the limiting member 65 in the first vertical groove 68, then allowing the limiting protrusion 67 to reach the connection between the first vertical groove 68 and the arcuate groove 69, and then rotating the limiting member 65 through an angle of 90 degrees, so that the limiting protrusion 67 reaches the connection between the second vertical groove 70 and the arcuate groove 69. Under the elastic force of the second spring 58, the limiting member 65 pushes the limiting protrusion 67 to the position within the positioning opening 71 to limit the limiting member 65.

[0065] 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 .

[0066] When the first docking assembly 7 and the second docking assembly 8 are docked, the handle 37 is in the vertical groove 35, so the first docking assembly 7 can be directly inserted into the second docking assembly 8 to complete the docking operation and realize the connection between the liquid cooling pipe 5 and the PACK module 4.

[0067] When disassembling, it is only necessary to push the handle 37 from the vertical slot 35 into the horizontal slot 34, so that the unlocking member 12 can be kept to drive 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.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
