[0042] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0043] Example 1

[0044] Existing energy storage devices typically require direct disconnection of the cabinet during maintenance, making it difficult to quickly power down individual energy storage units as needed, impacting the normal operation of the remaining units. Furthermore, the installation and wiring of existing energy storage devices are cumbersome, making it difficult to disconnect the energy storage power supply and cabinet as needed, and to switch between them while powered on for maintenance.

[0045] In view of this, an embodiment of the present invention provides a cabinet-type energy storage machine, including: a mounting frame 3 and an energy storage unit 6, the energy storage unit 6 is slidably installed on the mounting frame 3, the energy storage unit 6 is connected to a plug 502, a socket 501 is provided in the mounting frame 3, and the plug 502 can be plugged into or separated from the socket 501; the energy storage unit 6 is provided with a power assembly, the socket 501 is provided with a first cavity, a transmission assembly is provided in the first cavity, the transmission assembly includes a first clamping block 513, and the plug 502 is provided with a first clamping slot 514. When the plug 502 is plugged into the socket 501, the power assembly can move toward the first cavity and act on the first clamping block 513, so that the first clamping block 513 is clamped in the first clamping slot 514.

[0046] See Figure 1 and Figure 2 The cabinet-type energy storage system consists of a cabinet 1 with a retractable door panel 2 on one side. Energy storage units 6 are mounted on a mounting frame 3 inside the door panel 2. The mounting frame 3 is provided with several placement cavities 4, with each energy storage unit 6 placed in a corresponding placement cavity 4. To repair an energy storage unit 6, simply open the door panel 2 and remove the energy storage unit 6 from the placement cavity 4 in the mounting frame 3.

[0047] See Figure 3 When the energy storage unit 6 needs to be powered off for maintenance, the energy storage unit 6 can be directly pulled out, so that the plug 502 fixed to the energy storage unit 6 moves away from the socket 501, and the plug 502 and the socket 501 are powered off. At this time, the energy storage unit 6 can be powered off for maintenance. After maintenance, when the energy storage unit 6 needs to be tested or repaired live, the staff operates the energy storage unit 6 to drive the plug 502 to plug into the socket 501 for power connection, and then operates the power assembly to move toward the first cavity in the socket 501. The power assembly will act on the first clamping block 513 through the transmission assembly in the first cavity, so that the first clamping block 513 is locked in the first clamping groove 514, thereby ensuring the stability of the connection between the plug 502 and the socket 501 during the live testing or live maintenance of the energy storage unit 6. At this time, the socket 501 can also move outward along with the plug 502 and the energy storage unit 6 to facilitate the staff to perform live maintenance or live testing operations on the energy storage unit 6.

[0048] The cabinet-type energy storage machine can adjust the connection status between the socket 501 and the plug 502 according to actual needs, and can select the maintenance power state of the energy storage unit 6. While improving the convenience of use, it reduces unnecessary plug-in wear between the socket 501 and the plug 502, effectively improving the protection and practicality of the equipment during use.

[0049] In an optional manner of this embodiment, the power assembly includes a hand crank 505, a screw 504, a threaded sleeve 506, a connecting block 507, a fixed plate 508 and a conical block 509. The hand crank 505 is rotatably connected to the screw 504, the screw 504 is threadedly connected to the threaded sleeve 506, one end of the connecting block 507 is connected to the threaded sleeve 506, and the other end is connected to the fixed plate 508, the conical block 509 is connected to one end of the fixed plate 508 away from the connecting block 507, and the conical block 509 can move toward the first cavity.

[0050] See Figure 7When the energy storage unit 6 needs to be tested or repaired under power after maintenance, the staff first operates the energy storage unit 6 to drive the plug 502 into the socket 501 for power connection, and then manually operates the hand crank 505 to drive the screw 504 to rotate. The threaded connection between the screw 504 and the threaded sleeve 506 is used to transmit power to the threaded sleeve 506, and then the threaded sleeve 506 drives the connecting block 507, the fixing plate 508 and the tapered block 509 to move into the first cavity opened in the socket 501. The tapered block 509 acts on the first clamping block 513 through the transmission assembly, so that the first clamping block 513 is clamped in the first clamping groove 514, thereby ensuring that the plug 502 and the socket 501 are firmly connected during the live detection or live repair of the energy storage unit 6.

[0051] In an optional manner of this embodiment, the transmission assembly also includes a roller 510, a sliding block 511 and a cross plate 512. The roller 510 is arranged at the top of the first cavity, the sliding block 511 is connected to the bottom of the roller 510, the cross plate 512 is vertically connected to the sliding block 511, and the first clamping block 513 is connected to the bottom of the cross plate 512.

[0052] See Figure 5 and Figure 6 As the conical block 509 continues to move into the first cavity, the conical block 509 will squeeze the roller 510, the sliding block 511, the cross plate 512 and the first spring 522 downward, so that the cross plate 512 drives the first clamping block 513 to enter the first clamping groove 514 opened in the plug 502, thereby realizing a stable connection between the socket 501 and the plug 502.

[0053] In an optional manner of this embodiment, the socket 501 is provided with a locking assembly, which includes a main airbag 515, an air pipe 516, an auxiliary airbag 517 and a locking structure. The main airbag 515 is arranged in a first cavity below the horizontal plate 512. The socket 501 is also provided with a second cavity, and the auxiliary airbag 517 is arranged in the second cavity. The main airbag 515 and the auxiliary airbag 517 are connected through the air pipe 516, and the locking structure is connected to the auxiliary airbag 517.

[0054] See Figure 6 Under normal conditions, the locking assembly secures the socket 501 inside the mounting frame 3 via the locking structure. However, when a worker manually operates the hand crank 505 to continuously move the conical block 509 into the first cavity, the horizontal plate 512 compresses the primary airbag 515 during its downward movement, transferring the gas inside the primary airbag 515 to the interior of the secondary airbag 517 through the gas pipe 516. This causes the secondary airbag 517 to expand and act on the locking structure, thereby unlocking the socket 501 from the mounting frame 3 and allowing it to move toward the outside of the cabinet 1 along with the plug 502 and the energy storage unit 6.

[0055] Specifically, the locking structure includes a baffle 518, a second clamping block 520 and a fixed block 521. The baffle 518 is connected to the top of the auxiliary airbag 517, the second clamping block 520 is connected to the bottom of the baffle 518, and the fixed block 521 is fixedly arranged inside the mounting frame 3. The second clamping block 520 is plugged into the fixed block 521.

[0056] Please continue to see Figure 6 After the secondary airbag 517 inflates, it drives the baffle 518 and the second clamping block 520 upward. A second spring 519 is also provided at the top of the second cavity for cushioning. The second clamping block 520 moves out of the fixing block 521, releasing the second clamping block 520 from the fixing block 521, thereby releasing the socket 501 from the mounting bracket 3. The socket 501 can now be moved outside the cabinet 1 along with the plug 502 and the energy storage unit 6, facilitating live maintenance of the energy storage unit 6.

[0057] In an optional manner of this embodiment, a connecting frame 801 is further provided in the mounting frame 3, and the socket 501 is connected to the connecting frame 801 through a lead 804 assembly; the lead 804 assembly includes a lead 804, a winding shaft 802 and a torsion spring 803, the lead 804 is wound around the winding shaft 802, and the free end of the lead 804 is connected to the socket 501, and the torsion spring 803 is connected to the winding shaft 802.

[0058] See Figure 8 and Figure 9 During live maintenance or testing, socket 501 moves outward, causing the connecting frame 801 connected to it to move synchronously. At this point, socket 501 and connecting frame 801 drive reel 802 to rotate via lead wire 804, acting on torsion spring 803 connected to it. Once the test or maintenance is complete, torsion spring 803 resets socket 501 via reel 802 and lead wire 804, allowing lead wire 804 to be retracted.

[0059] In an optional manner of this embodiment, a protective frame 805 is provided in the mounting frame 3, the protective frame 805 is provided between the socket 501 and the connecting frame 801, the protective frame 805 is provided with a third cavity, and a limiting component is provided in the third cavity; the limiting component includes a third spring 806, a third clamping block 808 and a third clamping slot, the third clamping block 808 is connected to the top of the third spring 806, the third clamping slot is provided in the protective frame 805, and the third clamping block 808 can enter the third clamping slot under the action of the third spring 806.

[0060] See Figure 10During live maintenance, the outward movement of the socket 501, through the third spring 806, drives the third clamping block 808 into the third clamping slot, thereby fixing the sliding position of the socket 501 relative to the interior of the mounting frame 3 and limiting the use position of the connection frame 801, the socket 501, the plug 502, and the energy storage unit 6. This prevents the torsion spring 803 from causing the socket 501 to reset, thereby preventing the energy storage unit 6 from being pulled out and affecting the maintenance work. After completing the live maintenance, the operator can forcefully push the energy storage unit 6 to cause it to drive the plug 502 and the socket 501. At this time, the third spring 806 will release the limit between the third clamping block 808 and the third clamping slot, and the torsion spring 803 will reset the socket 501 through the reel 802 and lead 804.

[0061] In an optional manner of this embodiment, the protective frame 805 is further provided with a lead 804 protective assembly 8, which includes a connecting plate 807, a main liquid sac 809, an infusion tube, an auxiliary liquid sac 810 and a protective structure. The connecting plate 807 is arranged between the third block 808 and the main liquid sac 809, the main liquid sac 809 is connected to the auxiliary liquid sac 810 through the infusion tube, and the protective structure is connected to the auxiliary liquid sac 810.

[0062] The lead wire 804 protection component 8 can protect the connection portion between the lead wire 804 and the socket 501 during the process of retracting the lead wire 804, thereby preventing fatigue bending at the connection portion between the lead wire 804 and the socket 501 during the process of just releasing the lead wire.

[0063] Specifically, the protection structure includes an annular plate 811 , an annular block 812 and a protection block 813 . The annular plate 811 is connected to the auxiliary liquid sac 810 . The protection block 813 is connected to the annular plate 811 via the annular block 812 . The fourth spring 814 plays a buffering role.

[0064] See Figure 10 After the live maintenance is completed, the staff pushes the energy storage unit 6 with force, so that the third card block 808 is disengaged from the third card slot. At this time, the third card block 808 is squeezed, so that the third card block 808 drives the connecting plate 807 to squeeze the main liquid capsule 809, and the liquid inside the main liquid capsule 809 is transported to the auxiliary liquid capsule 810 through the infusion tube connected thereto, so that the auxiliary liquid capsule 810 expands and drives the annular plate 811, the annular block 812 and the protective block 813 to move toward the outside of the connection frame 801, so as to enhance the protection of the outer peripheral side of the lead 804, prevent the lead 804 from bending at the connection between the lead 804 and the socket 501, and thus prevent the connection state and signal transmission stability from being affected for a long time.

[0065] In an optional manner of this embodiment, a support frame 9 is provided at the bottom of the energy storage unit 6, and an installation frame 11 is provided in the installation frame 3. The support frame 9 and the installation frame 11 are slidably matched. The support frame 9 is provided with a first through hole 10, and the installation frame 11 is provided with a heat dissipation through hole 702. The first through hole 10 is connected to the heat dissipation through hole 702.

[0066] See Figure 4 and Figure 8 , a fixing box 503 is provided on the side of the energy storage unit 6. The staff operates the energy storage unit 6 to drive the support frame 9 into the interior of the installation frame 11. At this time, the first through hole 10 is connected to the heat dissipation through hole 702, the ventilation component 7 works, and the exhaust fan 701 draws external cold air into the interior of the installation frame 3 through the rain cover on the outside of the door panel 2, and delivers it to the multiple energy storage units 6 through the heat dissipation through hole 702 and the first through hole 10, so that the cold air is evenly in contact with the multiple energy storage units 6, ensuring the heat dissipation uniformity and heat dissipation effect of the equipment during use. The installation frame 11 supports and installs the support frame 9 and the energy storage unit 6, so that multiple energy storage units 6 can be quickly installed inside the cabinet 1. And the use position between the support plate and the installation frame 11 can be adjusted to install energy storage units 6 of different sizes, thereby improving the practicality of the equipment during use.
