[0002] An energy storage box is an outdoor intelligent substation on the grid side based on the concept of "standard power distribution". It is composed of components such as a charger, an inverter, a storage battery, an isolation transformer, and a switch, and can convert direct current electrical energy into alternating current electrical energy.

[0003] China Patent Grant Publication No. CN213401392U discloses an energy storage box, which has an accommodation cavity formed inside. There are two groups of battery cells arranged in the accommodation cavity. Side air ducts are arranged on both sides of the accommodation cavity, and a middle air duct is arranged in the middle. An air flow driving mechanism is arranged on the box body to drive the air flow entering the accommodation cavity from the air inlet to flow through the side air ducts, the connecting air ducts, and the middle air duct in sequence and then flow out from the air outlet. And from the end of the box body with the air inlet to the end with the air outlet, the cross-sectional area of the side air duct and / or the connecting air duct gradually decreases. For the energy storage box described in the utility model, from the end of the box body with the air inlet to the end with the air outlet, since the cross-sectional area of the side air duct and / or the connecting air duct gradually decreases, the air volume flowing into each connecting air duct can be made relatively close, so as to improve the consistency of the heat exchange effect of each battery cell and the consistency of the temperature difference of the battery cells.

[0004] However, this device has the following defects when in use: Although the accommodation cavity provided by this device can place the battery cells, the accommodation cavity does not have a relatively deep depth, and a large number of battery cells cannot be installed in a box body with a limited length, which will cause the box body to be unable to be installed in an area with a limited length. Moreover, the battery cells installed in the accommodation cavity at a high position are not convenient for disassembly and maintenance, which has certain limitations. In view of the above defects: For this reason, we propose a large box-type energy storage device. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0028] Please refer to Figures 1-4 , the present invention provides a technical solution: a large box-type energy storage device, including: a box body 1, a battery storage structure, a driving structure, an auxiliary sliding structure, and a limiting structure.

[0029] A closing door 2 is provided on the surface of the box body 1. Closing the closing door 2 can protect the components inside the box body 1.

[0030] The battery storage structure includes an outer frame 3, an inner frame 5 rotatably mounted on the inner wall of the outer frame 3 through a rotating shaft 4, and a plurality of partition plates 6 fixedly mounted on the inner wall of the inner frame 5 at equal intervals. The battery packs can be arranged and mounted on the plurality of partition plates 6.

[0031] The driving structure is arranged on the surface of the outer frame 3 and is used to drive the inner frame 5 to rotate. It includes a worm wheel 7 and a worm 8 that are respectively rotatably installed on the front surface of the outer frame 3, and a motor 9 that is fixedly installed on the front surface of the outer frame 3 and can drive the worm 8 to rotate. The worm wheel 7 is in meshing transmission with the worm 8. The back surface of the worm wheel 7 extends into the interior of the outer frame 3 and is fixedly connected to the front surface of the rotating shaft 4. The driving motor 9 can drive the worm 8 to rotate, and by using the meshing transmission between the worm wheel 7 and the worm 8, the inner frame 5 can be driven to rotate.

[0032] The auxiliary sliding structure is arranged between the outer frame 3 and the box body 1. The auxiliary sliding structure includes a plurality of slide rails 10 that are respectively equidistantly and fixedly installed on the inner top wall and the inner bottom wall of the box body 1, a roller 11 arranged on the bottom surface of the outer frame 3, and pulleys 12 respectively arranged on the top surface and the bottom surface of the outer frame 3. The pulleys 12 are in rolling cooperation with the slide rails 10. The bottom surface of the roller 11 is at the same height as the bottom surface of the box body 1, and a placement groove 13 adapted to the roller 11 is provided on the front surface of the box body 1.

[0033] When the outer frame 3 enters and exits the box body 1, at this time, the pulley 12 will slide on the inner wall of the slide rail 10, and the roller 11 will contact the ground. The rolling friction can facilitate the sliding of the outer frame 3. At the same time, the contact between the roller 11 and the ground can support the bottom of the outer frame 3, thereby improving the stability of the outer frame 3 during movement.

[0034] After the battery pack is installed on the partition plate 6 in the battery storage structure, the outer frame 3 can be slid into the box body 1. Compared with the prior art, after the battery pack is installed on the partition plate 6, the outer frame 3 is pulled out of the box body 1 by a sliding method. On the one hand, the box body 1 has a deeper depth, and a large number of battery packs can be installed without a long box body 1 to store a large number of battery packs. On the other hand, after the outer frame 3 is pulled out of the box body 1, the battery packs in the inner frame 5 can be exposed. Then, the driving structure can be used to drive the inner frame 5 to rotate by ninety degrees, so that the battery packs at the high position in the inner frame 5 can be rotated to the low position, which is convenient for the installation and disassembly and maintenance of the battery packs on the partition plate 6.

[0035] The limiting structure is arranged between the outer frame 3 and the box body 1 and is used to limit the battery storage structure. The limiting structure includes a limiting plate 14 fixedly installed on the bottom surface of the outer frame 3 and a groove 15 opened on the front surface of the box body 1, and the groove 15 allows the limiting plate 14 to be inserted. Bolt holes are provided on the surfaces of the groove 15 and the limiting plate 14.

[0036] After the outer frame 3 slides into the box body 1, at this time, the roller 11 will be in the placement groove 13, and the limiting plate 14 will be in the groove 15. Then, an external bolt can be screwed into the bolt hole, so that the outer frame 3 and the box body 1 can be fixed as a whole to prevent the outer frame 3 from moving.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art who makes equivalent substitutions or changes according to the technical solution and concept of the present utility model shall be covered by the protection scope of the present utility model.
