DETAILED DESCRIPTION

[0039] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0040] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0041] This embodiment provides a battery pack storage device for an energy storage cabinet, wherein a possible implementation thereof includes:

[0042] Frame unit 1, frame unit 1 can be welded using aluminum profiles or steel frames. Frame unit 1 is provided with multiple stations 10 along the height direction. Each station 10 can accommodate a battery pack 9. A support structure is provided at the bottom of the station 10 to support the battery pack. A locking structure is provided at the front to fix the battery pack in the station 10 to prevent it from unexpectedly falling out. When unlocked, the battery pack 9 can be pulled out of the station 10 and detached from the support structure, making it easier to replace or repair and inspect, or to lift it up from the station. When lifting the battery pack upward, the battery pack can only be pulled out a little distance and cannot completely detach from the station. The support structure of the upper station cannot hinder the upward movement path of the lower battery pack. Therefore, the support structure and the unlocking structure need to be specially designed. The implementation method of the specific structure will be given as an example later.

[0043] Track unit 2 is set on the upper side of the top station 10, with the track direction along the side, and has two working positions: parallel to the horizontal plane and close to the back side. When in the horizontal state, it can carry a battery pack. The upper surface of the track unit 2 is provided with a sliding support structure or a rolling support structure (such as Figure 2 When the battery pack is placed on the track unit 2, it can be pushed along the track unit 2 with minimal force, thereby being transported laterally along the frame. When the track unit 2 is in a working position close to the back side of the frame unit 1, the battery packs 9 on each workstation 10 of the frame unit 1 can be lifted to a position higher than the track unit 2, thereby placing the battery packs 9 on the track unit 2;

[0044] And, the lifting unit 3 is provided above the track unit 2 and is used to lift the battery pack 9 and switch the position between the work station 10 and the track unit 2. The lifting unit 3 includes a motor and a winding drum. The winding drum is connected to a sling, which is fixed to the battery pack 9 through the sling, and then the battery pack is lifted;

[0045] Multiple frame units 1 and track units 2 are arranged sideways to form a frame row. The track units 2 on the connected frame units 1 are docked with each other, so that in the same row, after the battery pack 9 is transferred to the track unit 2, it can move along the entire row of frame units 1. After reaching the outermost side, it is sent out of the energy storage system and a new battery pack for replacement is sent in. The above frame row can be further arrayed into an energy storage matrix, such as Figure 10 shown.

[0046] In conjunction with the display device of the above embodiment, this embodiment provides a specific operation method for replacing a battery pack:

[0047] Step 1: Determine the frame row where the battery pack to be replaced is located, the frame unit number of the frame row, and the station number (layer number) in the current frame unit;

[0048] Step 2: The track unit 2 of the current frame unit 1 moves to the working position close to the back side, such as Figure 3 As shown, leave space for the battery to pass through; the track units 2 of the other frame units 1 in the same row are kept in a working position parallel to the horizontal plane, as shown Figure 2 As shown, a track is formed for the batteries to be transported laterally along the frame rows;

[0049] Step 3: Lift the battery pack with the lifting unit 3. If there are other battery packs on the upper layer of the battery pack 9 to be replaced, the other battery packs need to be lifted from top to bottom. In the specific operation, first lift the top battery pack to a position higher than the track unit 2, and then move the track unit 2 to the working position parallel to the horizontal plane ( Figure 2) is aligned with the rails of the other frame units 1 on both sides. Next, the lifting unit 3 is lowered to a higher level, and the battery pack 9 is placed on the rail unit 2, and to one side (for example Figure 10 Then, repeat the second step, that is, restore the track unit 2 to the working position close to the back side ( Figure 3 ), leaving space for the battery to pass through, continue to lift the lower battery pack, and adjust the position of track unit 2 to Figure 2 , lower the battery onto the track.

[0050] Step 4: After the battery pack to be replaced or repaired is lifted above the track unit 2, the track unit 2 moves to a working position parallel to the horizontal plane and aligned with the tracks of the other frame units 1 on both sides. Next, the lifting unit 3 is lowered, and the battery pack 9 is placed on the track unit 2. The battery pack is gently pushed to the other side (left side) to move along the frame row. After moving to the end of the frame row, the battery pack leaves the energy storage matrix and is fed into the energy storage matrix for replacement. The new battery pack is then returned to the workstation along the same route.

[0051] Step 5: After the new battery pack is placed in the workstation, the other battery packs are also placed back in the same position. To reduce the number of times other battery packs need to be lifted each time a battery pack is replaced, the battery packs can be placed back in a specific order from high to low. For example, the battery in the best condition should be placed at the bottom layer, and the battery in the worst condition should be placed at the top layer. This way, the battery most likely to be replaced next time will be the top one, so it can be lifted only once, eliminating the need for a secondary lift. For taller frame units, a convenient and lightweight ladder can be provided to allow operators to inspect the battery packs on higher floors.

[0052] This energy storage cabinet battery pack display device and its supporting operation method have shown significant advantages in the field of energy storage technology:

[0053] By designing a collaborative working mechanism among the frame units, track units, and lifting units, rapid battery pack replacement and installation are achieved. No external machinery (such as forklifts) is required to enter the energy storage matrix area for removal and transfer operations, allowing for smaller spacing between the frame rows of the energy storage matrix, resulting in higher density and improved space utilization. Operators can conveniently transfer battery packs laterally along the frame rows to the edge of the matrix using the track units, effectively reducing the time and labor required for battery pack replacement. The modular design of the frame units and track units allows the energy storage matrix to be flexibly expanded according to actual needs. Multiple frame units and track units are arranged laterally into frame rows, which are then further arranged into energy storage matrices. This not only improves space utilization but also enhances the system's scalability and maintainability. By implementing a specific battery pack placement strategy, such as sorting by battery condition from worst to best, the number of times other packs need to be lifted for each battery pack replacement is reduced, improving overall O&M efficiency and reducing maintenance costs, thus providing a strong guarantee for the long-term stable operation of the energy storage system.

[0054] This embodiment can be found in Figure 2 and Figure 3 The track unit 2 includes a fixed rail 20 and a movable rail 21. The fixed rail 20 is fixedly installed on the rear structure of the frame unit 1, and the movable rail 21 is hinged to the rear structure of the frame unit 1. When it is turned to a horizontal angle, it is parallel to the fixed rail 20. When it is turned to an inclined angle (sticking to the back of the frame), the upper space of the workstation 10 is vacated, and the rotation angle is controlled by the power source. The rotation angle of the movable rail 21 does not exceed 90°. An electric push rod can be used as the power source, or a motor connected to a hinge shaft can be used as the power source. Since there is no battery pack on the movable rail 21 during the flipping process, the required flipping torque is very small, and a low-power power source can be used to save costs. When it is in the horizontal working position, it needs to bear the weight of the battery pack, so its bottom can be in contact with the top of the frame unit to form a supporting effect, such as Figure 2 The movable rail can meet different working requirements at different angles. When horizontal, it carries the battery pack and provides support. When tilted, it leaves space for workstations, improving space utilization and facilitating battery pack replacement.

[0055] This embodiment can be found in Figure 4 and Figure 6 The support structure includes a rear support 11 and a front support. The rear support 11 is arranged on the rear side structure of the frame unit 1 to support the tail of the battery pack 9. It can be a profile fixed to the frame unit as a whole. The front support includes two separately arranged support parts 12, which are respectively arranged on the opposite sides of the front side structure of the frame unit 1.

[0056] For matching, see Figure 9, there are concave grooves on both sides of the battery pack. Initially, the rear support 11 supports the tail of the battery pack, and the two support parts 12 respectively support the two sides of the front of the battery pack, specifically the front sides of the inner groove on the battery pack. When the battery pack needs to be lifted, first fix the sling to the battery pack, then pull the battery pack outward, the tail of the battery pack is separated from the rear support 11, and the inner groove at the front of the battery pack moves forward to align with the support part 12. At this time, the battery pack is lifted (other battery packs on the upper layer have been removed in advance, and the top movable rail 21 is also in Figure 3 (As shown), the battery pack can move upward without being blocked by the support structures of other stations above. After moving to the upper side of the track unit 2, the movable rail 21 returns to its equilibrium position, and the lifting unit 3 can prevent the battery pack from being on the track, and the sling is disconnected from the battery pack.

[0057] The above embodiment utilizes a rear support and separate dual front supports. The rear support is fixed to the rear of the frame, while the front supports are located on either side. The battery pack is equipped with an internal groove. During lifting, the battery pack moves forward to align the groove with the front support, facilitating upward movement without being obstructed by support structures at other upper stations. This design provides stable support for the battery pack, allowing for smooth movement during lifting. It also coordinates with the track unit and lifting unit to ensure safe and efficient battery pack replacement, improving the operational efficiency of the energy storage system.

[0058] For this example, please refer to Figure 5 , the locking structure is a screw 13 along the pulling-out direction of the battery pack 9, which is arranged in front of the front side of the frame unit 1. Matching this, locking holes are provided on both sides of the front side of the battery pack. When the battery pack needs to be replaced, unscrew the nut and pull out the battery pack for upward movement; after the battery pack is replaced, push in the battery and tighten the nut to fix the battery pack to the frame. A screw arranged in front of the front side of the frame unit along the pulling-out direction of the battery pack is used as a locking structure, in conjunction with the locking holes on both sides of the front side of the battery pack. The battery pack is locked and unlocked by twisting the nut, and the operation is simple and direct. This design makes the replacement operation of the battery pack more convenient and efficient. The staff can quickly complete the fixing and disassembly of the battery pack, effectively saving the battery pack replacement time, improving the maintenance efficiency of the energy storage equipment, and ensuring the fixation of the battery pack.

[0059] This embodiment can be found in Figure 7 and Figure 8 , the lifting unit 3 includes a first guide rail 30, a first driving mechanism, a side slide 32, a second driving mechanism 33, a front slide 34 and a crane 35;

[0060] The first guide rail 30 is arranged along the array direction of the frame unit 1 and can be fixed to an external structure (such as the ceiling of the energy storage room). The side slide 32 is slidably mounted on the first guide rail 30 and driven by the first drive mechanism to slide laterally. When the crane lifts the battery pack, the lateral movement of the lifting unit 3 can drive the entire battery to move along the track without the need for manual push. The front slide 34 is slidably mounted on the side slide 32 and driven by the second drive mechanism 33 to slide forward and backward. The crane 35 is set on the front slide 34, and the sling 350 of the crane 35 is used to lift the battery pack 9. The side slides 32 and the front slide 34 allow the motor (battery pack) to move laterally and forward and backward relative to the frame row. The lifting unit of this embodiment innovatively constructs a multi-stage sliding structure. Based on the first guide rail along the array direction of the frame unit, lateral sliding is achieved by the side slide and the first drive mechanism, and forward and backward sliding is achieved by the front slide and the second drive mechanism. The crane is installed on the front slide. This design breaks down the movement of the battery pack after lifting into independent lateral and forward and backward motions, automatically controlled by a drive mechanism, eliminating the limitations of manual movement. This allows the battery pack to be moved to its target location more effortlessly and flexibly after lifting, significantly reducing the difficulty and labor intensity of manual operation, improving the efficiency and safety of battery pack replacement, and significantly facilitating the operation and maintenance of energy storage systems.

[0061] At the end of the energy storage frame row, the end of the first guide rail 30 exceeds the edge of the frame row, so that the lifting unit 3 can move to the area below where there is no frame unit 1 and track unit 2, thereby directly lowering the battery pack to the ground, or lifting the battery pack from the ground and placing it into the track unit 2.

[0062] In the above embodiment, in one possible implementation of the first driving mechanism, it includes a screw and a motor, the screw is arranged along the array direction of the frame unit 1, both ends are rotatably connected to the external structure and driven by the motor, and the middle section is threadedly engaged with the side slide 32.

[0063] In the above embodiment, in one possible implementation of the second driving mechanism 33, the second driving mechanism 33 is a telescopic cylinder, which is located between the side slide 32 and the front slide 34, the shell is fixedly connected to either the side slide 32 or the front slide 34, and the telescopic shaft is fixedly connected to the other component.

[0064] This embodiment can be found in Figure 9 , Figure 11 and Figure 12 , an automatic unhooking device is provided at the end of the sling 350, including a main rod 351, a hanging rod 352 and a switching power source;

[0065] One end of the main rod 351 is connected to the sling 350, and the other end is suspended in the air and is provided with a rotation slot 3511;

[0066] The hanging rod 352 is rotatably disposed in the rotating groove 3511 and has two working states: coaxial with the main rod 351 and tilted, which are switched by switching the power source.

[0067] The switching power source includes two telescopic parts arranged in back-to-back directions. Both telescopic parts are located inside the hanging rod 352 and both face away from the rotation connection point between the hanging rod 352 and the main rod 351. The extension axes of the two telescopic parts are both toward the outer end of the hanging rod 352 and a counterweight body 3521 is provided at the end.

[0068] Rubber isolation layers 3522 are provided on the outer sides of both ends of the hanging rod 352 , and strain gauges are provided between the rubber isolation layers 3522 and the hanging rod 352 .

[0069] To match this, a corresponding structure is provided on the battery pack, which is mainly a hole located on both sides of the battery pack. The hole can be designed to be conical, with the conical hole larger at the top and smaller at the bottom, so as to facilitate the alignment and insertion of the automatic unhooker.

[0070] The working principle of the above embodiment is as follows: when the automatic unhooking device needs to be inserted into the tapered hole of the battery pack, the hanging rod 352 rotates to a coaxial state with the main rod 351. At this time, the hanging rod 352 is located inside the main rod 351 and is vertical. The main rod 351 and the hanging rod 352 can pass through the tapered hole of the battery pack and enter the bottom of the battery pack. Then the power source is switched to switch the state of the hanging rod 352 relative to the main rod 351, so that the two are in a relatively inclined working state. Then the crane tightens the cable, and the automatic unhooking device will gradually be in a state as shown in the figure. Figure 11 When unlocking is required, the crane first loosens the sling, and then makes the hanging rod 352 coaxial with the main rod 351. At this time, the sling and the automatic unhooker can be taken out from the tapered hole of the battery pack.

[0071] In the above embodiment, the principle of changing the state of the hanging rod 352 is that the torque at both ends of the hanging rod 352 changes, and the middle part of the hanging rod 352 is rotated. If the extension amount of the telescopic members at both ends is consistent, the torque at both ends is consistent, and the telescopic member will maintain a balanced state and be nearly perpendicular to the main rod 351. If the torque at both ends is inconsistent, the telescopic member will flip to a certain angle and tilt with the main rod 351. Even when the hanging rod 352 is coaxial and vertical with the main rod 351, if the counterweight at the upper end of the hanging rod 352 is greater than the counterweight at the lower end, the hanging rod 352 will automatically flip.

[0072] In the above embodiment, the rubber isolation layer 3522 can increase the friction force, make the contact more stable when lifting the battery pack, and protect the bottom of the battery pack. A strain gauge is a sensor that can convert mechanical deformation (such as stretching, compression, etc.) into a change in resistance. It is composed of a sensitive grid, etc., affixed to the surface of the object to be measured, and changes the resistance as the object deforms. By measuring the change in resistance, the strain of the object can be inferred. In this embodiment, the strain gauge can detect the tension between the hanging rod 352 and the battery pack, thereby determining the pulling force of the hanging rod 352 on the battery pack during the hanging process, ensuring effective connection with the battery before lifting.

[0073] The automatic unhooking device features an innovative structure, combining a main rod and a hanging rod. The hanging rod can be switched between coaxial and tilted relative to the main rod. This is achieved by switching the power source (two back-facing telescopic parts and a counterweight), utilizing the principle of torque change to change the hanging rod's state, allowing for flexible operation. A rubber isolation layer is placed on the outside of each end of the hanging rod to increase friction and protect the bottom of the battery pack. A strain gauge is placed between the rubber isolation layer and the hanging rod to convert mechanical deformation into resistance changes, accurately detecting the mutual force between the hanging rod and the battery pack. Conical holes are provided on both sides of the battery pack to facilitate alignment and insertion of the automatic unhooking device, matching the automatic unhooking device structure for efficient connection.

[0074] The automatic decoupler also improves device compatibility. Its design matches the tapered hole of the battery pack, allowing the automatic decoupler to connect to the battery pack quickly and accurately. It can be used with holes of different specifications (the hole diameter can be less than the length of the hanging rod 352), enhancing the versatility of the device in different scenarios.

[0075] The automatic uncoupler makes the lifting process more automated. The operator uses a handheld remote control to control the forward, backward, left and right movement of the lifting unit, the tightness of the crane, and the status of the automatic uncoupler. This can simplify the battery pack replacement process, reduce the degree of direct manual participation in battery replacement, and improve the maintenance efficiency of the energy storage system.
