[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a battery cluster of an energy storage cabin, the energy storage cabin includes a frame body 1 composed of multiple frame columns, a battery cluster 3 is arranged in the frame body 1, the battery cluster 3 includes a main frame 4 constructed by frame rods and having multiple battery installation layers, energy storage batteries are arranged in the battery installation layers, a lower fastener is provided at the bottom of the main frame 4 and fixedly connected to the bottom of the frame body 1, a switch box 5 is provided at the top of the main frame 4, a switch assembly 52 is provided in the switch box 5, and the switch assembly 52 is connected to the energy storage batteries in the battery installation layer, a connecting piece is provided on the main frame 4, one end of the connecting piece is connected to the top of the main frame 4, and the other end is connected to the inner top of the frame body 1 through an upper fastener, The upper and lower ends of the main frame 4 are firmly fixed by the upper fasteners and the lower fasteners, which effectively improves the shock resistance. By providing a switch box 5 at the top of the main frame 4, the switch assembly 52 is used to control the opening or closing of the battery cluster 3, so that each battery cluster 3 has an independent switch control system to prevent the battery clusters 3 from being affected by each other. In actual use, one or more battery clusters 3 can be allowed to work in turn, which effectively avoids overheating of the battery cluster 3 and increases the service life of the battery cluster 3. If a battery cluster 3 fails, it can be repaired separately, and the remaining battery clusters 3 can work normally, thereby not affecting the work efficiency.

[0025] The switch box 5 is hollow inside, with an opening at the bottom. A mounting plate 51 is provided at the lower end of the switch box 5, a through hole is provided in the middle of the mounting plate 51, a partition 53 is provided at the lower end of the switch assembly 52, and a harness interface 54 is provided on the switch box 5. The switch box 5 is fixed to the top of the main frame 4 through the mounting plate 51, and a partition 53 is provided at the lower end of the switch assembly 52. ​​The partition 53 reduces the contact area with the battery cluster 3, which can reduce the heat transferred from the battery cluster 3 during operation, effectively improves the heat dissipation, and prevents overheating. The harness interface 54 can be conveniently connected to the battery mounting layer.

[0026] In practical application, the connecting member includes ear frames 6 located at opposite sides of the top of the main frame 4, and a through hole is provided in the middle of the ear frame 6, and the through hole is arched. By providing a through hole in the middle of the ear frame 6, it is convenient for the user to put his hand into the switch assembly 52 of the opening and closing box through the through hole.

[0027] In practical applications, the upper fastener includes a mounting lug 7, and the mounting lug 7 is connected to the ear frame 6 through a waist hole.

[0028] The mounting ear 7 is in an "L" shape, and comprises a vertical section, and a flange extending inward is provided at the top end of the vertical section.

[0029] The flange is provided with a mounting hole for easy connection with the frame 1.

[0030] Yes, the ear frame 6 is provided with a transverse waist hole, and the mounting lug 7 is provided with a longitudinal waist hole. Alternatively, the ear frame 6 is provided with a longitudinal waist hole, and the mounting lug 7 is provided with a transverse waist hole. When in use, the position of the mounting lug 7 can be adjusted by the cooperation of the transverse and longitudinal waist holes and fixed by bolts, so as to facilitate the installation of the mounting lug 7.

[0031] like Figure 5 The frame rod comprises a longitudinal rod 8 and a cross rod 9 located in the main frame 4 , the longitudinal rod 8 comprises a front longitudinal rod 81 and a rear longitudinal rod 82 , and the front longitudinal rod 81 and the rear longitudinal rod 82 are fixed by a plurality of cross rods 9 .

[0032] A side plate 10 is provided between the front longitudinal rod 81 and the rear longitudinal rod 82 , and a rear plate 11 is provided between the rear longitudinal rod 82 . The rear plate 11 is provided with a plurality of heat dissipation holes.

[0033] An upper plate is provided at the upper end of the main frame 4 , and the switch box 5 is fixed on the upper plate through a mounting plate 51 .

[0034] In actual application, the main frame 4 is provided with a high-voltage control box 12 connected to the topmost battery installation layer and a plurality of energy storage battery boxes 13 which are sequentially plugged in below the high-voltage control box 12. The high-voltage control box 12 is provided with a controller, and the switch assembly 52 is connected to the controller. The existing high-voltage control box is often installed at the bottom of the battery cluster 3. Since the bottom is where heat accumulates, a cooling device or a heat dissipation device needs to be provided separately, which is very inconvenient. When it is set at the top, the absorbed heat is greatly reduced, and the cooling device (such as air conditioner) generally provided in the energy storage cabin can prevent overheating. There is no need to provide a cooling device or a heat dissipation device next to the high-voltage control box 12, which plays an energy-saving role.

[0035] In actual application, a tray 14 is provided in each battery installation layer, and the high-voltage control box 12 and the energy storage battery box 13 are installed on the tray 14 .

[0036] The tray 14 is connected to the crossbar 9 .

[0037] A plurality of heat dissipation holes are provided on the high voltage control box 12 and the energy storage battery box 13 .

[0038] In practical applications, a second limiting plate 16 is provided behind the energy storage battery box 13. The second limiting plate 16 enables the energy storage battery box 13 to be installed in the correct position, and the second limiting plate 16 can further fix the two rear longitudinal rods 82, thereby improving the stability of the main frame 4.

[0039] Both sides of the second limiting plate 16 are fixed on the rear longitudinal rod 82 .

[0040] In practical applications, a first limiting plate 15 is provided at the rear of the high-voltage control box 12, and both sides of the first limiting plate 15 are fixed on the tray 14. Since the high-voltage control box 12 is generally smaller in volume than the energy storage battery box 13, it is easy to slide when installed in the battery installation layer, and the first limiting plate 15 can prevent the high-voltage control box 12 from being installed unsecurely.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
