Utility Model Content

[0004] The purpose of this invention is to solve the problem of the inability to quickly fix battery packs in the prior art, and to propose an energy storage battery cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An energy storage battery cabinet includes a cabinet body and multiple battery packs disposed within the cabinet body. Multiple support plates are horizontally arranged within the cabinet body, and the multiple battery packs are respectively placed on the upper surface of the multiple support plates. The battery packs slide on the surface of the support plates via sliding components.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-7 An energy storage battery cabinet includes a cabinet body 1 and multiple battery packs 4 disposed within the cabinet body 1. A partition 2 is vertically fixed inside the cabinet body 1, dividing the interior of the cabinet body 1 into a battery cavity and a control cavity. A battery management system, an energy management system, and a fire protection system are disposed in the control cavity. Multiple support plates 3 are horizontally disposed inside the battery cavity. Multiple battery packs 4 are respectively placed on the upper surfaces of the multiple support plates 3. Heat dissipation gaps are respectively provided between the battery packs 4 and the inner walls of the battery cavity. The battery packs 4 slide on the surface of the support plates 3 via a sliding assembly 5. The sliding assembly 5 includes two symmetrically opened grooves 501 on the upper surface of the support plates 3. Multiple balls 503 are arranged in an array on the bottom wall of the two grooves 501. Two guide rods 502 are symmetrically fixed on the lower surface of the battery packs 4. The two guide rods 502 slide in the two grooves 501 via the multiple balls 503. Both the guide rods 502 and the grooves 501 are square. Chamfers are provided at the openings above the two grooves 501 to increase the opening width.

[0028] Understandably, the battery pack 4 slides along the inner walls of the two slide grooves 501 via the guide rod 502, which facilitates the positioning of the battery pack 4 and maintains the gap between the battery pack 4 and the battery cavity. Since the battery pack 4 is relatively heavy, multiple ball bearings 503 are provided to allow the battery pack 4 to slide, thereby reducing the friction between the guide rod 502 and the slide groove 501, making it easier for the battery pack 4 to slide and convenient to push the battery pack 4 into the cabinet 1 or pull the battery pack 4 out of the cabinet 1 for maintenance.

[0029] Specifically, the bearing plate 3 has multiple sets of fastening components 6 arranged inside for fixing the battery pack 4. The fastening components 6 include through slots 601 symmetrically opened on the sides of two guide rods 502. The bearing plate 3 has a cavity inside, and two insert rods 602 slide symmetrically inside the cavity. Pull rods 603 are hinged to the sides of the two insert rods 602. The other ends of the two pull rods 603 are hinged to moving blocks 604. Threaded rods 7 are threadedly connected to the surfaces of multiple moving blocks 604. The threaded rods 7 are rotatably connected inside the cavity. One end of the threaded rod 7 extends out of the bearing plate 3, and a handle is fixedly connected to the outer end of the threaded rod 7. The through slots 601 and the insert rods 602 near the through slots 601 are funnel-shaped. The through slots 601 and the insert rods 602 cooperate. The guide rods 502 are limited by the length of the sliding grooves 501 to make the through slots 601 correspond to the insert rods 602.

[0030] It is understandable that by rotating the handle, the threaded rod 7 is driven to rotate, causing the threaded rod 7 to drive multiple moving blocks 604 to move simultaneously, causing the pull rod 603 to change the connection angle. Under the action of the pull rod 603, multiple insert rods 602 are pushed to slide inside the bearing plate 3, so that the insert rods 602 are inserted into the through groove 601. Under the action of the funnel shape, the insert rods 602 can be pressed tightly into the through groove 601 of the guide rod 502, thereby quickly fastening multiple points of the battery pack 4 and achieving the purpose of rapid fixation.

[0031] Specifically, the cavity is equipped with a limiting component 8 for unidirectional limiting of the insertion rod 602. The limiting component 8 includes multiple limiting grooves 801 formed on the side of the insertion rod 602. A connecting rod 802 slides inside the bearing plate 3. The sliding direction of the connecting rod 802 is perpendicular to the sliding direction of the insertion rod 602. A limiting block 803 is fixed to one end of the connecting rod 802 near the limiting groove 801. Both the limiting block 803 and the limiting groove 801 have inclined surfaces. The limiting block 803 cooperates with the limiting groove 801 to prevent the insertion rod 602 from disengaging from the through groove 601. A spring 804 is fixedly connected to the side of the connecting rod 802. The other end of the spring 804 is fixedly connected to the inner wall of the cavity. The spring 804 is used to drive the limiting block 803 to be inserted into the limiting groove 801. The end of the connecting rod 802 away from the limiting block 803 extends out of the outer side of the bearing plate 3.

[0032] Understandably, when the insertion rod 602 is inserted into the through groove 601, the inclined surface prevents the limiting block 803 from obstructing the insertion rod 602. The spring 804 pushes the connecting rod 802 to insert the limiting block 803 into the limiting groove 801. With the cooperation of the limiting block 803 and the limiting groove 801, the insertion rod 602 is unidirectionally limited to prevent it from leaving the through groove 601. By limiting one insertion rod 602, the entire fastening assembly 6 is locked, preventing other insertion rods 602 from leaving the through groove 601.

[0033] Specifically, the surface of the cabinet 1 is provided with heat dissipation components 9 for independently dissipating heat from multiple battery packs 4. The heat dissipation components 9 include a protective shell 901 fixed to one side of the cabinet 1, multiple air inlets on the side of the protective shell 901, multiple cooling fans 902 fixedly connected inside the protective shell 901, multiple air outlets 903 on the back of the cabinet 1, and heat insulation layers 10 are respectively provided on the lower surface of multiple support plates 3. The heat insulation layers 10 are made of aerogel heat insulation pads. Two protective doors are hinged to the front surface of the cabinet 1, and the two protective doors respectively seal the battery cavity and the control cavity.

[0034] Understandably, by operating multiple cooling fans 902, air is supplied into the battery cavity through the air inlet and discharged through the air outlet 903, thereby removing the heat generated during the operation of the battery pack 4. Under the action of multiple support plates 3, the multiple battery packs 4 are separated to form independent spaces. When one battery pack 4 experiences thermal runaway, it prevents the heat from being rapidly transferred to the surface of other battery packs 4, causing damage to them. At the same time, by setting up aerogel heat insulation pads, heat transfer is further reduced. When the fire-fighting system cools down the thermally runaway battery pack 4, the independent spaces can prevent fire-fighting agents from drifting onto the surface of other battery packs 4 and affecting them, thus preventing greater losses.

[0035] In this invention, after the battery pack 4 is placed on the upper surface of the support plate 3, the battery pack 4 slides along the inner walls of the two sliding grooves 501 via the guide rod 502. The length of the sliding grooves 501 limits the position of the battery pack 4, aligning the through groove 601 with the insertion rod 602. By rotating the handle, the threaded rod 7 is rotated, causing multiple moving blocks 604 to move simultaneously. This changes the connection angle of the pull rod 603, and under the action of the pull rod 603, multiple blocks are pushed... The insertion rod 602 slides inside the support plate 3, allowing it to insert into the through groove 601. Under the action of the funnel shape, the insertion rod 602 is pressed tightly into the through groove 601 of the guide rod 502, quickly securing multiple points of the battery pack 4. Then, the spring 804 pushes the connecting rod 802, causing the limiting block 803 to insert into the limiting groove 801. With the cooperation of the limiting block 803 and the limiting groove 801, the insertion rod 602 is unidirectionally limited, preventing it from being inserted... 602 disengages from the through slot 601. By limiting one of the plug rods 602, the entire fastening assembly 6 is locked, preventing other plug rods 602 from disengaging from the through slot 601. When the battery pack 4 is working, multiple cooling fans 902 operate, supplying air into the battery cavity through the air inlet and discharging it through the air outlet 903, thereby carrying away the heat generated during the operation of the battery pack 4. When one of the battery packs 4 experiences thermal runaway, the aerogel insulation pad can reduce heat transfer and prevent heat from rapidly transferring to the surface of other battery packs 4, causing damage to other battery packs 4. At the same time, the fire protection system cools down the thermally runaway battery pack 4. When it is necessary to pull out the battery pack 4, the connecting rod 802 is pulled, causing the limiting block 803 to disengage from the limiting slot 801, releasing the limitation on the plug rod 602. Then, the multiple plug rods 602 are pulled out from the through slot 601 through the threaded rod 7, thereby pulling the battery pack 4 out of the cabinet 1 for inspection or replacement.
