[0037] Two support frames 5 are fixedly mounted on the middle stand 6 , and the middle stand 6 is simultaneously engaged and connected with two combination frames 2 on the adjacent cabinets 1 through the two support frames 5 .

[0038] The reinforcement mechanism includes a plurality of positioning bevel grooves 7 which are evenly spaced on the support frame 5, the side panels 3 and the combined frame body 2; a positioning bevel block 8 is slidably installed in the positioning bevel grooves 7 on the combined frame body 2; a fixing frame 9 is installed between the plurality of longitudinally corresponding positioning bevel blocks 8, and a moving round rod 10 is fixedly connected in the fixing frame 9; a driving cross bar 11 is slidingly fitted on the upper and lower end surfaces of the interior of the cabinet body 1; sliding frames 12 are symmetrically fixed on the left and right sides of the driving cross bar 11; a connecting frame 13 is fixedly installed between the upper and lower corresponding sliding frames 12 in the cabinet body 1; the moving round rod 10 is slidably connected to the sliding frame 12, and the sliding frame 12 is tilted and fixed on the driving cross bar 11.

[0039] According to the needs of electricity use, the number of installed power energy storage devices is first calculated, and the size of the installation space inside the energy storage cabinet is planned based on the number, so that the corresponding number of cabinets 1 are combined and installed. When assembling multiple cabinets 1, the cabinets 1 are arranged and distributed horizontally, and the two combined frames 2 at the connection of adjacent cabinets 1 are connected in a close fit, and the middle frame 6 is aligned with the two fitted combined frames 2 front and back. The two support frames 5 on the middle frame 6 are simultaneously engaged with the two adjacent combined frames 2. Through the engagement connection between the support frame 5 and the combined frame 2, the two adjacent cabinets 1 can be quickly assembled with each other, the outer side combined frame 2 of the outermost cabinet 1 is engaged with the side panel 3 for installation, and the side frame 4 on the front side of the side panel 3 is assembled on the front end surface of the cabinet 1. Through this partial installation structure, multiple cabinets 1 can be quickly assembled with each other, and the assembly operation is very convenient.

At this time, the movable round rod 10 connected to the sliding frame 12 moves accordingly, and the movable round rod 10 drives the fixed frame 9 and the positioning bevel block 8 to move synchronously, so that the positioning bevel block 8 moves from the inside of the positioning bevel groove 7 in the combined frame 2 to the positioning bevel groove 7 inside the side panel 3 and the support frame 5. The positioning bevel block 8 is snap-fitted into the positioning bevel groove 7 inside the side panel 3 and the support frame 5, which can reinforce the installation of the support frame 5 and the side panel 3 with the combined frame 2, thereby reinforcing the mutual assembly of multiple cabinets 1.

[0041] Embodiment 2: Based on Embodiment 1, a limiting mechanism is also disclosed, and its specific structure is as follows: two support frames 14 are symmetrically fixed in the cabinet 1, and a plurality of support frames 15 are fixed at equal intervals between the left and right support frames 14; a limiting mechanism for limiting the installation position of the power storage device is provided on the support frame 15; the limiting mechanism includes a plurality of strip grooves 16 evenly spaced on the support frame 15, a holder 17 is slidably installed in the strip groove 16 on the support frame 15 closest to the back of the cabinet 1, and a lifting rod 18 is fixedly installed on the upper surface of the holder 17, and a limiting plate 19 is fixed at the lifting end of the lifting rod 18.

[0042] A heat sink 20 for assisting the heat dissipation of the power storage device is fixed on the upper surface of the limiting plate 19; a limiting back plate 21 for limiting the installation position of the power storage device is fixedly installed at the front end of the holder 17; a displacement inclined groove 22 is opened on the supporting bracket 15, and a slide frame 23 is slidably connected in the displacement inclined groove 22; a slip ring 24 is provided on the sliding sleeve of the lifting rod 18, and a fixed seat 25 is fixedly installed on the slip ring 24, the fixed seat 25 is fixedly connected to the limiting plate 19, and the fixed seat 25 is fixedly connected to the slide frame 23; the slide frames 23 on multiple supporting brackets 15 distributed longitudinally are interconnected by fixing rods 30.

[0043] The cabinet 1 is provided with a power assembly for driving the card seat 17 to move and controlling the movement of the driving cross bar 11. The power assembly includes a driven bracket 26 fixed on the lowest card seat 17, a threaded rod 27 is rotatably mounted on the bottom surface of the cabinet 1, and an internal threaded base 28 is rotatably mounted on the threaded rod 27; the internal threaded base 28 is fixedly connected to the driving cross bar 11 at the bottom of the cabinet 1; a push rod 29 is rotatably connected to the internal threaded base 28, and the other end of the push rod 29 is rotatably connected to the driven bracket 26.

[0044] The power storage devices are installed on the support frame 15 in sequence, and different power storage devices are connected to each other through cables. After assembling multiple cabinets 1, the threaded rod 27 below the internal storage space of the cabinet 1 is controlled to rotate. The threaded rod 27 is threadedly connected to the internal threaded base 28. The internal threaded base 28 is controlled to move in a directional manner under the thread transmission. The internal threaded base 28 is fixedly connected to the driving cross bar 11, and can control the driving cross bar 11 to move synchronously, thereby controlling the movement of the sliding frames 12 on both sides of the driving cross bar 11 to push the positioning bevel block 8 to move.

[0045] When the internal thread base 28 moves, the two ends of the push rod 29 connected between the internal thread base 28 and the driven bracket 26 rotate accordingly. The rotating push rod 29 pushes the card seat 17 to engage in the strip groove 16 and move horizontally. The card seat 17 drives the lifting rod 18, the slip ring 24, the fixed seat 25 and the slide frame 23 to move horizontally synchronously. When the slide frame 23 moves horizontally, it slides along the shifting inclined groove 22 on the support frame 15. The shifting inclined groove 22 is inclinedly opened on the support frame 15. The slide frame 23 moves along the direction of the shifting inclined groove 22 with a certain displacement in the longitudinal space, thereby driving the fixed seat 25 and the slip ring 24 to move longitudinally. The slip ring 24 is sleeved on the lifting rod 18. The outside slides longitudinally, and the fixed seat 25 drives the limit plate 19 and the lifting rod 18 to move up and down for adjustment. The limit plate 19 moves downward and is pressed onto the upper surface of the electric energy storage device on the support bracket 15, thereby firmly limiting the electric energy storage device on the support bracket 15 and maintaining the installation stability of the electric energy storage device. The sliding frames 23 on the upper and lower adjacent support brackets 15 are fixedly connected by the fixing rod 30. When the sliding frame 23 at the bottom of the cabinet 1 slides, the fixing rod 30 drives the upper multiple sliding frames 23 to move synchronously, thereby controlling the limit plates 19 on the multiple support brackets 15 to move up and down uniformly, and quickly and stably installing the multiple electric energy storage devices in the cabinet 1.
