[0036] The cabinet 1 adopts an open structure, and the rear cover 4 is set as a rotating structure at the rear of the cabinet 1. Under normal circumstances, the rear cover 4 is fixed by the cover fixing member 5. If the capacity of the power storage unit 12 of the cabinet 1 is insufficient, the rear cover 4 can be rotated to a horizontal state and supported by the supporting structure thereon. The pad 8 is in contact with the ground, and the buffer rod 9 on the support plate 7 can play a buffering role. The rear cover 4 is reinforced by the reinforcing rod 10 to ensure that its strength is sufficient to support the expansion unit 13.

The magnetic card block 36 adopts a rectangular parallelepiped structure and can enter the bottom of the top plate 21 through the limiting straight groove 22.

[0040] The expansion unit 13 is provided with a stabilizing foot 15. After it is assembled, the connection between the plug rod 18 and the stabilizing foot 15 can be used to further increase the stability of the expansion unit 13. After the magnetic card block 36 enters the bottom of the top plate 21 from the limiting straight groove 22, it can be rotated 90 degrees and blocked by the top plate 21. At the same time, the magnetic card block 36 generates a magnetic repulsive force on the magnetic end plate 20, so that the plug rod 18 overcomes the elastic force of the spring 19 and slides out of the slide seat 17, and is inserted into the slot 16 of the stabilizing foot 15 to fix the expansion unit 13.

At the same time, the magnetic card block 36 can generate a repulsive force on the magnetic end plate 20, so that the insertion rod 18 completes the synchronous fixation of the expansion unit 13, thereby ensuring that the expansion unit 13 can be used stably.

[0045] When the present invention is in use: first, the energy storage device of the present invention is a storage cabinet structure as a whole, which has the ability to move, can be freely moved according to the microgrid power generation test site, and is more flexible to use. After reaching the test position, it is fixed by the positioning member 3 so that it can stably maintain the connection with the power generation device. The cabinet 1 adopts an open structure, and the rear cover 4 is set to a rotating structure at the rear of the cabinet 1. Under normal circumstances, the rear cover 4 is fixed by the cover fixing member 5. If the capacity of the power storage unit 12 of the cabinet 1 is insufficient, the rear cover 4 can be rotated to a horizontal state and supported by the support structure thereon. The pad 8 is in contact with the ground, and the buffer rod 9 on the support plate 7 can play The rear cover 4 is reinforced by the reinforcing rod 10 to ensure that its strength is sufficient to support the expansion unit 13. After the rear cover 4 is rotated to a horizontal state, the assembly seat 11 thereon is set upward, and the expansion unit 13 can be supplemented.

The expansion unit 13 is provided with a stabilizing foot 15. After it is assembled, the connection between the insertion rod 18 and the stabilizing foot 15 can be used to further increase the stability of the expansion unit 13. After the magnetic card block 36 enters the bottom of the top plate 21 from the limiting straight groove 22, it can be rotated 90 degrees so as to be blocked by the top plate 21. At the same time, the magnetic card The block 36 generates a magnetic repulsion force on the magnetic end plate 20, so that the insertion rod 18 overcomes the elastic force of the spring 19 and slides out of the slide seat 17, and is inserted into the slot 16 of the stabilizing foot 15 to fix the expansion unit 13. In addition to assembling the expansion unit 13 on the rear cover plate 4, the heat dissipation pipeline can be further assembled, and water can be supplied by the water cooling structure to assist in the heat dissipation of the expansion unit 13. During assembly, the heat absorption pipe network 33 is assembled through the water supply pipe 30 and the return pipe 31. The cooling water in the circulating water tank 23 enters the water inlet pipe 27 from the water supply port 24, and then enters the water supply pipe 30 from the diversion port 29, passes through the heat absorption pipe network 33, fits the expansion unit 13 to take away the heat, and finally flows out from the return pipe 31, the water outlet pipe 28, and the water return port 25 return to the circulating water tank 23 to complete the heat dissipation work. The water supply pipe 30 and the return pipe 31 are initially installed through the sealing member 32, and the water supply pipe 30 and the return pipe 31 can be further fixed by the magnetic card block 36 on the connecting member 34. When the water supply pipe 30 and the return pipe 31 are installed, the magnetic card block 36 is inserted along the limiting straight groove 22, and then the magnetic card block 36 is driven to rotate 90 degrees through the control member 37 so that it is clamped under the top plate 21, which has the effect of fixing the pipe fittings. At the same time, the magnetic card block 36 can generate a repulsive force on the magnetic end plate 20, so that the insertion rod 18 completes the synchronous fixation of the expansion unit 13, ensuring that the expansion unit 13 can be used stably.
