Description

Technical Field

[0001] The utility model relates to the technical field of energy storage systems, and in particular to a battery pack limiting structure of an energy storage battery cabinet. Background Art

[0002] Since the energy people need is highly time- and space-dependent, in order to make rational use of energy and improve energy utilization, a device is needed to collect and store excess energy that is temporarily unused for a period of time, and then extract and use it during peak usage, or transport it to places where energy is scarce for use. This method is energy storage.

[0003] The fundamental task of an energy storage system is to overcome the temporal or localized differences between energy supply and demand. A battery energy storage system is a relatively common energy storage system, primarily consisting of an energy storage battery cabinet and various control devices. When assembling the energy storage battery cabinet, multiple battery packs are inserted into the load-bearing rails within the cabinet, and then screwed into the front of the battery pack to secure it to the load-bearing rails. However, due to space constraints, once the battery pack is inserted into the load-bearing rails, the rear end becomes inoperable, preventing the rear end of the battery pack from being secured. This creates a gap between the rear end of the battery pack and the energy storage battery cabinet. During handling or transportation, the battery pack will vibrate violently due to this gap, which can easily cause damage to the battery pack and even lead to safety accidents. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a battery pack retaining structure for an energy storage battery cabinet includes a cabinet body, a support column 1 fixedly mounted therein, and multiple battery pack support rails 2 evenly spaced on the support column 1. The battery pack support rails 2 are used to place battery packs 3, and the battery packs 3 can slide on the battery pack support rails 2, thereby facilitating the pushing and removing of the battery packs 3 into or from the cabinet body. The front end of the battery pack support rail 2 is provided with a battery pack front end fixing hole 21, which is used to pass a bolt through the battery pack front end fixing hole 21 to secure the battery pack 3 to the front end, thereby connecting and fixing the front end of the battery pack 3 to the battery pack support rail 2. The rear end of the battery pack support rail 2 is provided with a battery pack rear end limiting fold 22. The battery pack 3 slides with the battery pack support rail 2, and the battery pack 3 can abut against the battery pack rear end limiting fold 22. By pushing the battery pack 3 to slide on the battery pack support rail 2 until the rear end of the battery pack 3 abuts against the battery pack rear end limiting fold 22, the rear end of the battery pack 3 is limited by the battery pack rear end limiting fold 22. The battery pack support rail 2 is provided with a battery pack upper end limiting assembly, which limits the upper end surface of the battery pack 3. The battery pack front end fixing hole 21, the battery pack rear end limiting fold 22, and the battery pack upper end limiting assembly cooperate to limit and fix the battery pack 3 on the battery pack support rail 2, thereby solving the problem of the battery pack 3 shaking due to the gap and solving the problem of the battery pack 3 being damaged or causing safety accidents during handling and transportation.

[0024] The battery pack upper end limit assembly includes a rotating member 4 and a pulling member 5. The rotating member 4 is rotatably connected to the battery pack support rail 2. One end of the pulling member 5 is connected to the rotating member 4, and the other end is movably limited and connected to the battery pack support rail 2. The pulling member 5 can drive the rotating member 4 to rotate, thereby causing the rotating member 4 to abut or separate from the upper end surface of the battery pack 3. During the installation of the battery pack 3, the battery pack 3 is placed on the battery pack support rail 2, and then the battery pack 3 is pushed and slid on the battery pack support rail 2 until the rear end of the battery pack 3 abuts against the battery pack rear end limit flange 22; at this time, the fixing screw hole on the battery pack 3 is also exactly aligned with the battery pack front end fixing hole 21, and the front end of the battery pack 3 is fixed to the battery pack support rail 2 by screwing in the fixing bolt; finally, by operating the pulling member 5, the rotating member 4 is rotated until the rotating member 4 abuts against the upper end surface of the battery pack 3, thereby limiting and fixing the battery pack 3 on the battery pack support rail 2.

[0025] The rotating member 4 includes a connecting portion 41 and a limiting portion 42. The connecting portion 41 is hinged to the battery pack carrying guide rail 2 and the pulling member 5 respectively. One end of the limiting portion 42 is fixedly connected to the connecting portion 41, and the other end can abut against the upper end face of the battery pack 3. Specifically, a rotating shaft 6 is provided on the battery pack carrying guide rail 2, and the connecting portion 41 is rotatably connected to the rotating shaft 6. When in use, after the battery pack 3 is pushed onto the battery pack carrying guide rail 2 until the rear end face of the battery pack 3 abuts against the rear end limiting fold 22 of the battery pack, by pulling the pulling member 5, the connecting portion 41 can be driven to rotate on the battery pack carrying guide rail 2 along the rotating shaft 6 as the axis, driving the limiting portion 42 to move together until the limiting portion 42 abuts against the upper end face of the battery pack 3, thereby achieving the purpose of limiting the upper end face of the battery pack 3.

[0026] To prevent the limiting portion 42 from crushing the upper end surface of the battery pack 3, a flexible protective block 43 is provided at the end of the limiting portion 42 away from the connecting portion 41. The flexible protective block 43 ensures soft contact between the limiting portion 42 and the upper end surface of the battery pack 3, preventing embossing or crushing of the battery pack 3. The flexible protective block 43 can be made of a flexible material such as rubber.

[0027] In order to limit and guide the rotation direction of the rotating part 4, a limiting guide part 7 is provided at a position corresponding to the rotating part 4 on the battery pack carrying guide rail 2, and the connecting part 41 and the limiting guide part 7 are slidably limited and connected; through the cooperation between the connecting part 41 and the limiting guide part 7, the rotation direction of the rotating part 4 can be limited and guided, so that the limiting part 42 can abut against the upper end surface of the battery pack 3, and the battery pack 3 is limited and fixed on the battery pack carrying guide rail 2.

[0028] Specifically, one end of the position-limiting guide member 7 is connected to the battery pack support rail 2, and the other end is sleeved around the periphery of the connecting portion 41 and slidably engages with the connecting portion 41. In this embodiment, the position-limiting guide member 7 is riveted to the battery pack support rail 2 via rivets. The other end has a bent edge, which forms a gap with the sidewall of the battery pack support rail 2 that is appropriate to the thickness of the connecting portion 41. The connecting portion 41 of the rotating member 4 passes through this gap and can slide within it, thereby achieving the purpose of rotationally limiting and guiding the rotating member 4.

[0029] A connecting shaft 8 is mounted on the rotating member 4. One end of the pulling member 5 is rotatably connected to the connecting shaft 8, so that the pulling member 5 can pull the rotating member 4 to rotate. A threaded rod 9 is provided at the other end of the pulling member 5. A front fixing plate 10 is provided on the battery pack support rail 2. The threaded rod 9 and the front fixing plate 10 are adjustable and limit-connected. When installing the battery pack 3, the threaded rod 9 and the front fixing plate 10 are first loosened. This allows the threaded rod 9 to be pushed, and then the pulling member 5 to be pushed, so that the rotating member 4 rotates upward so that the battery pack 3 can be pushed onto the battery pack support rail 2. When the rear end face of the battery pack 3 abuts against the rear end limit fold 22 of the battery pack, the threaded rod 9 is pulled to drive the pulling member 5, driving the rotating member 4 to rotate downward until the limit portion 42 abuts against the upper end face of the battery pack 3. The threaded rod 9 is then connected and fixed to the front fixing plate 10, thereby fixing the rotating member 4 to prevent the battery pack 3 from loosening due to the rotation of the rotating member 4 during use.

[0030] Specifically, a limiting bending edge 11 is provided on the front end fixing plate 10, and the end of the threaded rod 9 away from the pulling member 5 passes through the limiting bending edge 11. A first limiting nut 12 is provided on the threaded rod 9, and the first limiting nut 12 is threadedly connected to the threaded rod 9, and the first limiting nut 12 can abut against the side of the limiting bending edge 11 away from the pulling member 5. During the installation of the battery pack 3, first loosen the first limiting nut 12 so that the threaded rod 9 can be pushed into the limiting bent edge 11, so that the pulling member 5 pushes the rotating member 4 to rotate upward, so as to push the battery pack 3 into contact with the limiting bent edge 22 at the rear end of the battery pack; when the battery pack 3 is installed in place, pull the threaded rod 9 to drive the pulling member 5, so that the rotating member 4 rotates downward until the limiting portion 42 abuts against the upper end surface of the battery pack 3; then tighten the first limiting nut 12 until the first limiting nut 12 abuts against the limiting bent edge 11; and then the limiting of the first limiting nut 12 can prevent the threaded rod 9 from retracting, thereby realizing the limiting function of the pulling member 5 and the rotating member 4.

[0031] In order to prevent the rotating member 4 from rotating downward due to gravity when the battery pack 3 is installed, a second limiting nut 13 is provided on the threaded rod 9. The second limiting nut 13 is threadedly connected to the threaded rod 9 and can abut against the side of the limiting bent edge 11 close to the pulling member 5. When installing the battery pack 3, the first limiting nut 12 is first loosened, and then the threaded rod 9 is pushed in the direction close to the rotating member 4. The threaded rod 9 will drive the pulling member 5 and thus push the rotating member 4 to rotate upward. When the limiting portion 42 rotates upward to the appropriate position, the second limiting nut 13 is tightened until the second limiting nut 13 abuts against the side of the limiting bent edge 11 close to the pulling member 5, thereby preventing the rotating member 4 from automatically rotating downward. After the battery pack 3 is installed in place, loosen the second limiting nut 13, pull the threaded rod 9 to drive the pulling member 5 and thereby pull the rotating member 4 to rotate downward until the limiting portion 42 abuts against the upper end surface of the battery pack 3; then tighten the first limiting nut 12 and the second limiting nut 13 respectively; until the first limiting nut 12 and the second limiting nut 13 abut against the two sides of the limiting bending edge 11 respectively.

[0032] By providing the first limiting nut 12 and the second limiting nut 13, not only the rotating part 4 can be limited, but also it can play a role in preventing loosening, avoiding the situation where the nuts become loose due to vibration during transportation or handling, thereby improving the stability of the structure.

[0033] In this embodiment, the rotation angle of the rotating member 4 on the battery pack support rail 2 is 0-130°, preferably 0-79°. The specific angle value can be adaptively set according to the side thickness of the battery pack 3. It is only necessary to ensure that after the rotating member 4 rotates upward, the battery pack 3 can be smoothly pushed onto the battery pack support rail 2 until the rear end of the battery pack 3 abuts the battery pack rear limit flange 22.

[0034] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
