[0020] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model discloses a battery pack storage device, including a container 1, a partition board 2 is arranged in the container 1, the partition board 2 divides the internal space of the container 1 into a storage area and an abnormal processing area, at least one shelf 3 for placing multiple battery packs is arranged in the storage area, a fire-retardant box 4 with a top opening is arranged in the abnormal processing area, and a transfer mechanism 5 for transferring battery packs with abnormal temperature from the shelf 3 to the fire-retardant box 4 is also arranged in the container 1.

[0022] The utility model places the collected battery packs on the shelf 3. When it is detected that the temperature of one of the battery packs is abnormal, the transfer mechanism 5 automatically removes the battery pack from the shelf 3 and transfers it to the fire-retardant box 4. By isolating the abnormal battery packs, the location where the fire occurs is controlled, and the loss in the event of a fire accident is reduced. At the same time, the transfer mechanism 5 can be used to transfer the abnormal batteries in time, avoiding the situation where the discovery and transfer are not timely, thereby increasing the fire loss.

[0023] It should be noted that a flame detector is provided in the container 1, which detects the temperature of the battery packs at various locations in the container 1 in real time to promptly detect temperature abnormalities, and transmits the abnormal point information to the controller when an abnormal situation occurs. The controller is used to operate the transfer mechanism 5 to automatically complete the transfer of the abnormal battery pack. The flame detector and the controller are both mature existing technologies and will not be elaborated on here.

[0024] In the specific implementation, it is necessary to lay fireproof panels on the inner wall of the container 1 to improve the fireproof performance of the container 1. At the same time, a temperature and humidity controller and an explosion-proof air conditioner can be installed in the container 1 to keep the temperature and humidity inside the container 1 constant.

[0025] In one embodiment, the shelf 3 is composed of a plurality of columns 31 and a plurality of layers 32 arranged between the plurality of columns 31. The height of the layer 32 from the ground on the side close to the transfer mechanism 5 is less than the height of the layer 32 from the ground on the side away from the transfer mechanism 5. A baffle 33 perpendicular to the layer 32 and penetrating the layer 32 is provided on the layer 32 by a torsion spring. When the battery pack contacts the baffle 33, the baffle 33 still maintains a perpendicular position to the layer 32. A rotation hole is provided on the layer 32 for the baffle 33 to rotate to a state parallel to the layer 32.

[0026] The transfer mechanism 5 includes a refractory box 51 and a four-axis motion platform 52 for driving the refractory box 51 to move linearly and rotate in three axes. The four-axis motion platform 52 is installed at the top of the inner cavity of the container 1. A channel for moving batteries into the side wall of the refractory box 51 is opened. A sealing component 53 that can be opened and closed is provided at one end of the channel. A top frame 54 is provided at the other end of the channel for pushing the baffle 33 to rotate when the refractory box 51 is close to the layer plate 32. The height of the channel from the ground on the side close to the sealing component 53 is less than the height of the channel from the ground on the side close to the top frame 54.

[0027] Such a design enables the four-axis motion platform 52 to simultaneously push the baffle 33 to flip while driving the side of the fire-resistant box 51 equipped with the top frame 54 to approach the shelf 32, thereby releasing the restriction of the baffle 33 on the battery pack, allowing the battery pack to automatically slide from the inclined shelf 32 to the fire-resistant box 51, completing the transfer of the battery pack from the shelf 3 to the transfer mechanism 5. After that, it is only necessary to control the four-axis motion platform 52 to drive the side of the fire-resistant box 51 equipped with the blocking component 53 to move to the fire-resistant flame-retardant box 4, and then open the blocking component 53, so that the battery pack can slide out of the fire-resistant box 51 and fall into the fire-resistant flame-retardant box 4.

[0028] It should be noted that in order to improve the space utilization of the storage area, there can be two shelves 3, and the transfer mechanism 5 is located between the two shelves 3. The refractory box 51 is rotated and the direction of the top frame 54 is adjusted through the four-axis motion platform 52 to realize the subsequent retrieval of battery packs on different shelves 3.

[0029] In one embodiment, a plurality of rollers 34 penetrating the layer plate 32 are rotatably disposed on the layer plate 32 , the diameter of the rollers 34 is greater than the thickness of the layer plate 32 , and a belt conveyor 55 for contacting the rollers 34 and driving the rollers 34 to rotate is disposed on the top frame 54 .

[0030] This design utilizes the rollers 34 to reduce the frictional resistance of the battery pack movement. At the same time, the belt conveyor 55 contacts some of the rollers 34, driving the rollers 34 to rotate through friction, so that the rollers 34 actively push the battery pack to transfer into the refractory box 51, thereby improving the transfer efficiency.

[0031] In one embodiment, a plurality of protruding balls are provided at the bottom of the channel. When the refractory box 51 is close to the layer plate 32, the highest height of the balls from the ground is less than the lowest height of the corresponding layer plate 32 from the ground, so that the battery pack is above the balls after entering the refractory box 51, thereby reducing the resistance of the battery pack to be moved out of the refractory box 51.

[0032] In one embodiment, the blocking assembly 53 includes a blocking plate 531 that can move up and down and a guide rail 532 for limiting the up and down movement distance of the blocking plate 531. The guide rail 532 is installed on the fireproof box 51. A convex strip 533 is provided on the side of the blocking plate 531 away from the fireproof box 51.

[0033] A connecting hole for connecting the storage area and the abnormality processing area is provided on the partition plate 2, and a crossbeam is provided on the connecting hole.

[0034] With this design, after the battery pack enters the refractory box 51, the four-axis motion platform 52 drives the refractory box 51 to move toward the partition board 2 while controlling the refractory box 51 to rotate, so that the sealing component 53 faces the partition board 2, and then controls the protrusion 533 to move above the beam. When the refractory box 51 is controlled to descend, the sealing plate 531 can be kept in place and no longer block the channel, so that the battery pack can slide into the fire-retardant box 4. After the sealing component 53 is away from the partition board 2, the sealing plate 531 can automatically reset under the action of gravity to prepare for the next transfer.

[0035] It should be noted that the container 1 is provided with a pressure relief valve and a fire sprinkler component located on the top of the fire-retardant box 4. When a battery pack catches fire in the fire-retardant box 4, the burning battery pack can be continuously cooled to reduce the impact of the fire. After the fire is over, the user can enter the abnormal handling area from the other side door of the container to deal with the residues in the fire-retardant box 4.

[0036] In a specific implementation, in order to ensure that the battery pack can be stably removed from the refractory box 51, another belt conveyor may be provided at the bottom of the channel of the refractory box 51 to accelerate the removal of the battery pack.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
