[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0044] See also Figures 1 to 13 In an embodiment of the present invention, an industrial energy storage device includes an energy storage cabinet 1, and a plurality of split compartments 2 fixedly installed in the energy storage cabinet 1; the plurality of split compartments 2 are fixedly connected vertically by connecting columns 201; and further includes a battery cell 3, the battery cell 3 being able to slide with the split compartment 2; a docking plate 4 is slidably provided in the split compartment 2; a wire post 8 is fixedly installed on a surface of the docking plate 4 away from the battery cell 3;

[0045] The split chamber body 2 is provided with a snap-fit ​​assembly; the snap-fit ​​assembly is connected to a stopper 5 that is slidably connected to the split chamber body 2; the stopper 5 is provided with a shock-absorbing assembly;

[0046] When the battery cell 3 is inserted into the split compartment 2 in the forward direction, the battery cell 3 drives the engaging assembly to move through the stopper 5; after the battery cell 3 is out of contact with the stopper 5, the engaging assembly drives the stopper 5 to reset, and after resetting, it continues to drive the stopper 5 to move until the shock absorbing assembly contacts and cooperates with the battery cell 3, thereby limiting the reverse displacement of the battery cell 3;

[0047] The battery cell 3 and the docking plate 4 can be stably connected through a docking assembly; and a buffer assembly connected to the docking plate 4 is provided on the split compartment 2, and the buffer assembly is used to support the battery cell 3 through the docking plate 4 after the docking assembly completes docking.

[0048] In this embodiment, the energy storage cabinet 1 is first fixedly installed in the energy storage power station site; the divided compartments 2 are used to support the battery cells 3, and each divided compartment 2 is separated by a connecting column 201 to increase the heat dissipation effect and reduce the impact of temperature on the battery cells 3.

[0049] In the initial state, the size of the battery cell 3 is the same as the inner wall size of the split chamber body 2, and the block 5 is partially exposed from the inner wall of the split chamber body 2; the shock absorbing assembly will conflict with the split chamber body 2, so that the shock absorbing assembly is completely immersed in the block 5, so that the movement of the block 5 is not affected.

[0050] During the forward insertion of the battery cell 3 into the split chamber 2, the battery cell 3 will contact the block 5 first and squeeze the block 5, so that the block 5 pushes the locking assembly to move, thereby giving way. At this time, the block 5 is flush with the inner wall of the split chamber 2, so that the battery cell 3 can be smoothly inserted into the split chamber 2; after the battery cell 3 is out of contact with the block 5, the locking assembly will drive the block 5 to reset, and it will continue to drive the block 5 to move after resetting; during the displacement process after the block 5 is reset, the shock absorbing assembly will break away from the interference of the split chamber 2, so that it can extend from the block 5 to contact and cooperate with the battery cell 3, thereby restricting the battery cell 3 and preventing it from escaping from the split chamber 2.

[0051] When the battery cell 3 is inserted into the split compartment 2 in the forward direction, the docking plate 4 will remain in position so that the docking assembly can successfully complete the docking of the battery cell 3 and the docking plate 4; after the docking is completed, the docking plate 4 will be in an active state, and the buffer assembly will support the battery cell 3 through the docking plate 4.

[0052] After all the battery cells 3 are installed, all the battery cells 3 are connected in series using wires and through the wire posts 8 so that the energy storage device is in normal working condition.

[0053] The block 5 is used to restrict the installed battery cell 3 from being separated from the split compartment body 2, so as to ensure the stable operation of the energy storage device; during the insertion of the battery cell 3, the shock absorbing assembly will always be immersed in the block 5 under the restriction of the split compartment body 2, so that the block 5 and the locking assembly can cooperate with each other; the locking assembly can provide the block 5 with the ability to make way, and after the battery cell 3 is out of contact with the block 5, the block 5 is driven to complete the reset first, and then continue to move until the split compartment body 2 is out of contact with the shock absorbing assembly; thereafter, the shock absorbing assembly will contact and cooperate with the battery cell 3, so that the installation of the battery cell 3 is smoother; the shock absorbing assembly and the buffer assembly can reduce the impact of vibration on the battery cell 3, thereby improving the stability of the wire connection on the wire post 8, and avoiding the battery cell 3 causing tension on the wire due to vibration, which leads to loose connection, thereby improving the safety of the energy storage device; the docking assembly can improve the stability of the docking between the battery cell 3 and the docking plate 4, so as to avoid loose connection and reduced safety of the energy storage device.

[0054] As a further solution of the present invention, the locking assembly includes a first yield groove 202 provided on the split chamber body 2, an engaging groove 205 provided in the first yield groove 202, a rotating plate 6 rotatably engaged with the stop block 5 is slidably engaged in the first yield groove 202, and a raised column 601 slidably engaged with the engaging groove 205 is fixedly installed on the rotating plate 6; a second yield spring 602 fixedly connected to the rotating plate 6 is fixedly installed in the first yield groove 202.

[0055] In this embodiment, the interlocking groove 205 consists of an inclined section and a vertical section. The distance between the end of the vertical section close to the stop block 5 and the stop block 5 is smaller than the distance between the end of the inclined section close to the stop block 5; in the initial state, the protruding column 601 is located in the inclined section close to the stop block 5.

[0056] During the contact and cooperation between the battery cell 3 and the block 5, the block 5 will be squeezed and slide into the first clearance groove 202, thereby driving the rotating plate 6 to move inward in the first clearance groove 202. At this time, the raised column 601 slides in the inclined section of the interlocking groove 205 toward the end away from the block 5, and drives the rotating plate 6 to rotate. When the block 5 completely enters the first clearance groove 202, the raised column 601 is just located at the end of the inclined section of the interlocking groove 205 away from the block 5 and enters the vertical section, and the second clearance spring 602 is compressed.

[0057] After the battery cell 3 is out of contact with the block 5, the elastic force of the second yielding spring 602 drives the rotating plate 6 to move outward in the first yielding groove 202. At this time, the raised column 601 moves in the vertical section of the interlocking groove 205 toward the end close to the block 5, thereby driving the block 5 away from the first yielding groove 202. When the raised column 601 reaches the end of the vertical section of the interlocking groove 205 close to the end of the block 5, the movement stops. During this process, the block 5 is first reset and then continues to move a distance. The block 5 is used to prevent the installed battery cell 3 from being separated from the split chamber 2 to ensure the stable operation of the energy storage device. The locking assembly can provide the block 5 with yielding ability, and after the battery cell 3 is out of contact with the block 5, it drives the block 5 to reset first and then continue to move until the split chamber 2 is out of contact with the shock absorbing assembly.

[0058] As a further solution of the present invention, the shock absorbing assembly includes a shock absorbing groove 501 opened on the side of the stop block 5 close to the docking plate 4, a shock absorbing plate 503 is slidably engaged in the shock absorbing groove 501, and a first shock absorbing spring 502 is fixedly installed in the shock absorbing groove 501, with its two ends respectively fixedly connected to the shock absorbing groove 501 and the shock absorbing plate 503.

[0059] In this embodiment, in the initial position, the split chamber 2 will contact the shock absorbing plate 503 and squeeze the shock absorbing plate 503 to make it completely immersed in the shock absorbing groove 501, and the first shock absorbing spring 502 is in a compressed state; when the battery cell 3 squeezes the stopper 5, the stopper 5 will bring the shock absorbing plate 503 into the first yielding groove 202, and the shock absorbing plate 503 will always be in contact with the split chamber 2; after the battery cell 3 is out of contact with the stopper 5, the locking assembly will drive the stopper 5 to move in the opposite direction, thereby driving the shock absorbing plate 503 to move. In this process, the shock absorbing The plate 503 will first maintain contact with the segmentation chamber body 2. When the block 5 stops moving, the shock-absorbing plate 503 will lose contact with the segmentation chamber body 2. At this time, the elastic force of the first shock-absorbing spring 502 will drive the shock-absorbing plate 503 to slide outward in the shock-absorbing groove 501 until the shock-absorbing plate 503 contacts the battery cell 3. The shock-absorbing component can reduce the impact of vibration on the battery cell 3, thereby improving the stability of the wire connection on the wire column 8, and avoiding the loose connection caused by the tension of the wire by the battery cell 3 due to vibration, thereby improving the safety of the energy storage device.

[0060] As a further solution of the present invention, the split warehouse body 2 is provided with a second give way groove 203; a connecting plate 7 is slidably installed in the second give way groove 203, and a third give way spring 701 fixedly connected to the connecting plate 7 is fixedly installed in the second give way groove 203, and the end of the connecting plate 7 close to the docking plate 4 is fixedly installed with a limit block 703 that slides with the split warehouse body 2; the end of the connecting plate 7 away from the docking plate 4 is fixedly installed with a wedge block 702 that slides with the split warehouse body 2.

[0061] In this embodiment, in the initial state, the limit block 703 contacts the side of the docking plate 4 away from the battery cell 3, so that the docking plate 4 cannot move in the direction away from the battery cell 3; in the process of docking the battery cell 3 with the docking plate 4 through the docking assembly, the battery cell 3 will contact the wedge block 702 first, and the wedge block 702 will be squeezed by the inclined surface of the wedge block 702, so that it drives the connecting plate 7 to slide inward in the second clearance groove 203, and the third clearance spring 701 will be compressed, and at the same time, the limit block 703 will be driven to move toward the connecting plate 7 through the connecting plate 7, gradually reducing the contact area with the docking plate 4; after the docking assembly completes the docking, the wedge block 702 will be completely immersed in the second clearance groove 203, so that the limit block 703 releases the restriction on the docking plate 4, so that the buffer assembly can support the battery cell 3 through the docking plate 4.

[0062] As a further solution of the present invention, the docking assembly includes a docking post 401 fixedly mounted on the docking plate 4, a contraction seam 402 is formed on the docking post 401, and an annular protrusion 405 is fixedly mounted on the docking post 401;

[0063] The docking assembly further includes a docking hole 305 and a locking groove 306 formed on the battery cell 3 .

[0064] In this embodiment, during the insertion of the battery cell 3 into the split chamber 2, the docking post 401 will be inserted into the docking hole 305; since the aperture of the docking hole 305 is smaller than the diameter of the annular protrusion 405, during the insertion process, the inner wall of the docking hole 305 will squeeze the annular protrusion 405, so that the gap of the shrinkage seam 402 is reduced; so that the docking post 401 can be smoothly inserted into the docking hole 305; the aperture of the engaging groove 306 is slightly larger than the diameter of the annular protrusion 405, and after the annular protrusion 405 enters the engaging groove 306, the gap of the shrinkage seam 402 will be restored, so that the engaging groove 306 and the annular protrusion 405 are engaged; the docking assembly can improve the stability of the docking between the battery cell 3 and the docking plate 4 to avoid loose connection and reduced safety of the energy storage device.

[0065] As a further solution of the present invention, the buffer assembly includes a shock-absorbing telescopic sleeve 403 fixedly installed on the side of the docking plate 4 away from the battery core 3, and a second shock-absorbing spring 404 is fixedly installed in the shock-absorbing telescopic sleeve 403; the end of the second shock-absorbing spring 404 away from the docking plate 4 is fixedly connected to a shock-absorbing telescopic column 204 fixedly connected to the split compartment 2, and the shock-absorbing telescopic column 204 slides with the shock-absorbing telescopic sleeve 403.

[0066] In this embodiment, after the limit block 703 releases the restriction on the docking plate 4, the docking plate 4 can move away from the battery cell 3. The elastic force of the first shock-absorbing spring 502 pushes the shock-absorbing plate 503 to contact the battery cell 3, and makes the battery cell 3 tend to push the docking plate 4 to move away from the battery cell 3.

[0067] When the docking plate 4 moves away from the battery core 3 , the shock-absorbing telescopic column 204 slides inwardly in the shock-absorbing telescopic sleeve 403 and compresses the second shock-absorbing spring 404 .

[0068] The shock-absorbing assembly and the buffer assembly can reduce the impact of vibration on the battery cell 3, thereby improving the stability of the wire connection on the wire column 8, and preventing the battery cell 3 from pulling the wire due to vibration and causing the connection to become loose, thereby improving the safety of the energy storage device. The elastic force of the second shock-absorbing spring 404 and the first shock-absorbing spring 502 can offset or reduce the impact of vibration on the energy storage device.

[0069] As a further solution of the present invention, a first telescopic sleeve 301 is fixedly installed on one end of the battery cell 3 close to the docking plate 4, a telescopic square column 303 is slidably engaged in the first telescopic sleeve 301, and a first yielding spring 302 fixedly connected to the telescopic square column 303 is fixedly installed in the first telescopic sleeve 301; a roller 304 is rotatably installed on the telescopic square column 303.

[0070] In this embodiment, when the battery cell 3 is inserted into the split chamber body 2, the split chamber body 2 will first contact the roller 304 and squeeze the roller 304, causing it to drive the telescopic square column 303 to slide inward in the first telescopic sleeve 301, and the first yield spring 302 will be compressed; the elastic force of the first yield spring 302 makes the roller 304 always in contact with the split chamber body 2, thereby reducing the difficulty of inserting the battery cell 3 into the split chamber body 2 and making installation more convenient.

[0071] As a further solution of the present invention, the energy storage cabinet 1 is provided with multiple groups of heat dissipation slots.

[0072] In this embodiment, since heat is generated when the energy storage device is working, the temperature of the energy storage cabinet 1 will increase as the heat accumulates. Excessive temperature will reduce the stability of the battery cell 3; the heat dissipation effect of the energy storage device can be increased through the heat dissipation groove.

[0073] An energy storage power station includes a plurality of the industrial energy storage devices described above.

[0074] In this embodiment, multiple industrial energy storage devices can significantly increase the energy storage capacity of the energy storage power station.
