Description

Technical Field

[0001] This invention belongs to the field of kinetic energy storage, specifically relating to an energy storage device based on the cascade utilization of waste batteries. Background Technology

[0002] Currently, kinetic energy storage involves converting mechanical kinetic energy into electrical energy before storing it in a power storage device. This storage process often utilizes power storage devices based on the cascade utilization of used batteries. The core of these devices consists of a cascaded battery pack, a storage cabinet, a load-bearing positioning mechanism, an installation and fixing mechanism, and auxiliary support and unlocking mechanisms. During battery pack installation, workers use forklifts to smoothly transport the sorted and reassembled cascaded battery pack to the designated location in the storage compartment, precisely aligning it with the rack installation area. The pack is then slowly lowered to complete the initial positioning, followed by manual leveling, bolt tightening, and insulation protection. High-voltage lines and BMS data acquisition harnesses are then connected sequentially, and protective and heat dissipation structures are added. After insulation testing and wiring verification, the entire battery pack installation is completed.

[0003] However, a slight deviation occurs when the battery pack is connected to the energy storage cabinet, requiring the forklift to repeatedly adjust the position. This requires high operational precision and driver skills, is time-consuming and labor-intensive, and seriously affects the installation efficiency. Summary of the Invention

[0008] As a preferred embodiment of the present invention, the power storage device based on the cascade utilization of waste batteries includes a positioning rod.

[0009] As a preferred embodiment of the present invention for a power storage device based on the cascade utilization of waste batteries, the support assembly includes an adjusting rod.

The top of the connecting plate is fixedly connected to an unlocking plate, one side of the unlocking plate is slidably connected to one side of the top of the positioning rod, and the bottom of the connecting plate is fixedly connected to a lower pressure plate. One side of the lower pressure plate is slidably connected to a support plate, and one side of the support plate is slidably connected to one side of the fixed frame.

[0010] As a preferred embodiment of the present invention, a power storage device based on the cascade utilization of waste batteries, a reset groove is provided on one side of the reset frame, a reset spring is fixedly connected to one side of the inner wall of the reset groove, and the other side of the inner wall of the reset groove is slidably connected to one side of the surface of the reset rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

[0016] 2. With the push plate and fixing plate in place, when the forklift lifts the carrier frame and battery pack body through the carrier plate during use, the carrier plate will drive the push plate to move closer to the carrier frame. The push plate will then push the fixing plate to flip and fix the position of the battery pack body within the carrier frame. This prevents the battery pack from shifting when it is placed into the energy storage cabinet body, thus ensuring the installation quality.

[0017] 3. With the installation of the fixed frame and support components, during use, the adjusting rod can be used to move the lower pressure plate through the connecting plate, and the lower pressure plate can be used to move the support plate downward. The cooperation between the support plate and the carrier frame keeps the carrier plate in a suspended state. When the connecting plate moves, it will also drive the unlocking plate to push the positioning rod away from the positioning plate, so that the carrier plate can move the push plate downward under the action of gravity. The fixed plate will flip under the cooperation of the torsion spring and the limit rod, which facilitates the replacement of the battery pack body on the carrier frame and improves the replacement efficiency.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example

[0022] Reference Figure 1 - Figure 7 This is the first embodiment of the present invention. This embodiment provides an energy storage device based on the cascade utilization of waste batteries, which achieves a corrective effect. It includes a corrective component, including a support column 10. A rectangular frame 11 is rotatably connected to one side of the support column 10. A reset component 12 is provided on one side of the rectangular frame 11. A support frame 13 is fixedly connected to the top of the rectangular frame 11. An energy storage cabinet body 14 is slidably connected to one side of the support frame 13. A battery pack body 15 is movably connected to the top of the support frame 13. A support plate 16 is slidably connected to the bottom end of the support column 10. An extension plate 17 is slidably connected to one side of the top of the support plate 16. The top of the extension plate 17 is slidably connected to the bottom end of the support frame 13.

[0023] Specifically, a forklift is used to deliver the carrier frame 13 and the battery pack body 15 into the appropriate position inside the energy storage cabinet body 14 via the carrier plate 16. When there is a slight deviation between the installation position of the battery pack body 15 and the energy storage cabinet body 14, the position of the battery pack body 15 can be corrected within a certain range by the energy storage cabinet body 14 with the cooperation of the carrier column 10 and the reset component 12.

[0024] Furthermore, the reset assembly 12 includes a reset frame 121, one side of which is fixedly connected to one side of the rectangular frame 11. A reset spring 122 is fixedly connected inside the reset frame 121. A reset rod 123 is fixedly connected to one end of the reset spring 122. One end of the reset rod 123 is fixedly connected to the inside of the support plate 16.

[0025] With the reset spring 122, when the position of the battery pack body 15 shifts during use, and the support column 10 causes the support plate 16 to change position on one side of the rectangular frame 11, the reset rod 123 can move within the reset frame 121. The elastic force of the reset spring 122 is used to automatically reset and correct the position of the support plate 16, so that the support plate 16 can return to its initial position after the battery pack body 15 is installed.

[0026] Preferably, a reset groove is provided on one side of the reset frame 121, a reset spring 122 is fixedly connected to one side of the inner wall of the reset groove, and the other side of the inner wall of the reset groove is slidably connected to one side of the surface of the reset rod 123. An extension groove is provided at the top of the support plate 16, and the inside of the extension groove is slidably connected to the surface of the extension plate 17.

[0027] It should be noted that by setting the reset groove, the movement trajectory of the reset rod 123 can be restricted during use, preventing the reset rod 123 from deviating during movement. By setting the extension groove, the movement trajectory of the bearing plate 16 can be restricted during use, preventing the bearing frame 13 from deviating when moving along the extension plate 17, thus ensuring the stability of the structural movement.

[0028] In use, first rotate the adjusting rod 311 on the fixing frame 30 to make the connecting plate 312 move the lower pressure plate 314 closer to the fixing frame 30. Since the side of the lower pressure plate 314 and the support plate 315 that are close to each other is provided with an inclined surface, the lower pressure plate 314 will push the support plate 315 to move downward during the movement. The cooperation between the support plate 315 and the carrier frame 13 will make the carrier plate 16 be in a suspended state. Then, place the battery pack body 15 on the carrier frame 13, and then insert the forklift fork into the bottom end of the carrier plate 16 and make the two fork arms move away from each other at the bottom end of the carrier plate 16 until they are in contact with the carrier plate. The bottom edges of the 16 are contacted. Then, using a forklift, the support frame 13 and the battery pack body 15 are lifted to a suitable position via the support plate 16. The adjusting rod 311 on the fixing frame 30 is rotated to make the connecting plate 312 move the lower pressure plate 314 away from the fixing frame 30, thereby allowing the lower pressure plate 314 to move the support plate 315 up. Then, the support plate 16 is moved by the forklift, and the support frame 13 and the battery pack body 15 are sent into a suitable position inside the energy storage cabinet body 14. When there is a slight deviation in the installation position of the battery pack body 15 and the energy storage cabinet body 14, multiple [missing information] are set on the support frame 13. One of the inclined planes will contact the main body 14 of the energy storage cabinet, causing the bearing frame 13 to shift its position relative to the bearing plate 16 with the cooperation of the bearing column 10 within the rectangular frame 11. During the movement of the bearing frame 13, a set of reset rods 123 on one side of one of the rectangular frames 11 will retract into the reset frame 121 and compress the reset spring 122 within the reset frame 121. Meanwhile, a set of reset rods 123 on the other side of the rectangular frame 11 will extend out of the reset frame 121 and stretch the reset spring 122 within the reset frame 121. When the forklift delivers the battery pack main body 15 into the appropriate position within the energy storage cabinet... After positioning, the forklift arms move closer together and lower, allowing the load-bearing frame 13 to contact the energy storage cabinet body 14. When the forklift arms disengage from the load-bearing plate 16, the load-bearing plate 16 will move under the reaction force generated by the two sets of return springs 122, correcting the position of the load-bearing plate 16 under the load-bearing frame 13 and returning it to its initial position. Then, the load-bearing frame 13 is left inside the energy storage cabinet body 14 to complete the installation. This facilitates the rapid installation of the battery pack body 15, which is assembled from waste batteries of different specifications after tiered screening, reducing the requirements for installation accuracy and effectively improving installation efficiency.

[0029] In summary, during the installation of the battery pack body 15, the position between the support frame 13 and the support plate 16 will shift within a certain range, thereby reducing the back-and-forth movement of the forklift, lowering the technical requirements for the driver, and improving installation efficiency. Example

[0030] Reference Figure 4 - Figure 7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an installation component for an energy storage device based on the cascade utilization of waste batteries, which solves the problem of shaking between the battery pack body 15 and the support frame 13 during installation. It includes an installation component, including a push plate 20. The bottom end of the push plate 20 is slidably connected to the top of the support plate 16 near the extension plate 17. A fixing plate 21 is slidably connected to one side of the push plate 20. A limiting component 22 is provided inside the fixing plate 21. A positioning plate 23 is fixedly connected to one side of the support plate 16. A positioning component 24 is provided on one side of the positioning plate 23.

[0031] Furthermore, when the forklift lifts the carrier frame 13 and the battery pack body 15 by means of the carrier plate 16, the carrier plate 16 will drive the push plate 20 to move closer to the carrier frame 13. The push plate 20 will push the fixing plate 21 to flip and fix the position of the battery pack body 15 in the carrier frame 13, so as to prevent the position of the battery pack in the carrier frame 13 from shifting when the battery pack body 15 is sent into the energy storage cabinet body 14.

[0032] Furthermore, the limiting component 22 includes a torsion spring 221, one end of which is fixedly connected to the inside of the fixed plate 21, and the other end of which is fixedly connected to a limiting rod 222. One end of the limiting rod 222 is fixedly connected to the top of the support plate 16 near the fixed plate 21. The positioning component 24 includes a positioning rod 241, one end of which is movably connected to the side of the positioning plate 23, and the other end of which is fixedly connected to a positioning spring 242. One end of the positioning spring 242 is fixedly connected to a positioning frame 243, and the top end of the positioning frame 243 is fixedly connected to the bottom of the support plate 16 near the fixed frame 30.

[0033] The torsion spring 221 allows for adjustment of the angle of the fixing plate 21 during use, thereby facilitating the fixing of the battery pack body 15 on the support frame 13.

[0034] Preferably, the fixing plate 21 has circular grooves on both sides, one side of the inner wall of the circular groove is fixedly connected to the other end of the torsion spring 221, and the other side of the inner wall of the circular groove is rotatably connected to one side of the surface of the limiting rod 222. The positioning plate 23 has a positioning groove on one side, and the interior of the positioning groove is movably connected to one end of the positioning rod 241. The bearing frame 13 has a fixing groove on one side, and the inner wall of the fixing groove is fixedly connected to the other end of the limiting rod 222.

[0035] It should be noted that the circular groove can limit the position of the torsion spring 221 and the limiting rod 222 during use, preventing the fixed plate 21 from shifting during rotation and ensuring the stability of the fixed plate 21 during flipping. The positioning groove facilitates the use of the positioning rod 241 to fix the distance between the bearing frame 13 and the bearing plate 16 during the correction of the bearing frame 13, ensuring that the bearing column 10 is always in contact with the bearing plate 16. The fixing groove restricts the position of the fixed plate 21, making it easy for the fixed plate 21 to flip around the limiting rod 222 as the axis during movement.

[0036] In use, after the support plate 315 is reset, when the forklift fork arm is inserted into the bottom end of the support plate 16 and the support plate 16 is lifted upward, the support plate 16 on the fork arm will drive the push plate 20 to slide along the trajectory of the extension plate 17 towards the support frame 13. During the sliding process, the push plate 20 will push the fixing plate 21 to flip around the limit rod 222. When the fixing plate 21 flips, it will drive the torsion spring 221 to twist and store force. When the support plate 16 is lifted to the preset position, the top of the fixing plate 21 has flipped to the side of the battery pack body 15 near the push plate 20, pressing the battery pack body 15 tightly against the inner wall of the support frame 13, completing the pre-fixation of the position of the battery pack body 15, avoiding the battery pack body 15 from shaking and shifting in the support frame 13 during the transfer and installation process, further reducing the probability of installation deviation and ensuring the connection stability after installation. As the support plate 16 rises, it also drives the positioning plate 23 to rise. At this time, one end of the positioning rod 241 slides on the surface of the positioning plate 23. When the support plate 16 is raised to the preset position, the positioning spring 242 in the positioning frame 243 will push the positioning rod 241 into the positioning groove in the positioning plate 23 to fix the distance between the support plate 16 and the support frame 13. When the support plate 16 moves, the push plate 20 will move horizontally on the support plate 16, and the positioning rod 241 will slide in the positioning groove in the positioning plate 23, thereby ensuring the stability between the battery pack body 15 and the support frame 13 during the correction process.

[0037] In summary, as the support plate 16 approaches the support frame 13, the push plate 20 drives the fixing plate 21 to flip, thereby firmly fixing the battery pack body 15 inside the support frame 13 and preventing the battery pack from shifting its position inside the support frame 13 when the battery pack body 15 is sent into the energy storage cabinet body 14. Example

[0038] Reference Figure 5 - Figure 7This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an auxiliary component for an energy storage device based on the cascade utilization of waste batteries, which solves the problem of cumbersome disassembly process. It includes an auxiliary component, including a fixing frame 30. The top of the fixing frame 30 is fixedly connected to the edge of the bottom end of the support frame 13. The fixing frame 30 is provided with a support component 31 inside.

[0039] Furthermore, the adjusting rod 311 can be used to drive the lower pressure plate 314 to move via the connecting plate 312. The lower pressure plate 314 can then drive the support plate 315 to move downwards. With the cooperation of the support plate 315 and the carrier frame 13, the carrier plate 16 is suspended in the air. As the connecting plate 312 moves, it will also drive the unlocking plate 313 to push the positioning rod 241 away from the positioning plate 23, allowing the carrier plate 16 to drive the push plate 20 to move downwards under the action of gravity. The fixing plate 21 is flipped over with the cooperation of the torsion spring 221 and the limiting rod 222, which facilitates the replacement of the battery pack body 15 on the carrier frame 13.

[0040] The support assembly 31 includes an adjusting rod 311. One side of the surface of the adjusting rod 311 is rotatably connected to the inside of the fixed frame 30. The other side of the surface of the adjusting rod 311 is threadedly connected to a connecting plate 312. The top of the connecting plate 312 is fixedly connected to an unlocking plate 313. One side of the unlocking plate 313 is slidably connected to one side of the top of the positioning rod 241. The bottom of the connecting plate 312 is fixedly connected to a lower pressure plate 314. One side of the lower pressure plate 314 is slidably connected to a support plate 315. One side of the support plate 315 is slidably connected to one side of the fixed frame 30.

[0041] Furthermore, with the connection plate 312 in place, during use, rotating the adjusting rod 311 will cause the connection plate 312 to move along the trajectory of the adjusting rod 311, thereby simultaneously causing the unlocking plate 313 and the pressing plate 314 to move synchronously. This eliminates the need to adjust the unlocking plate 313 and the pressing plate 314 separately, simplifying the operation steps and improving operational efficiency.

[0042] When using the battery pack, once used, it needs to be removed from the main body 14 of the energy storage cabinet for replacement. Using the forklift's forks, insert them into the bottom of the support plate 16 and lift it upwards. This moves the fixing frame 30 to a position easily accessible to the operator. Then, rotate the adjusting rod 311. The adjusting rod 311 rotates within the fixing frame 30, causing the connecting plate 312 to move along the adjusting rod 311 towards the support frame 13 via a thread. During the movement of the connecting plate 312, the unlocking plate 313 and the lower pressure plate 314 move synchronously. When the unlocking plate 313 moves, it pushes the top of the positioning rod 241, causing the positioning rod 241 to compress the positioning spring 242 and disengage from the positioning groove of the positioning plate 23, releasing the position lock on the support plate 16. The lower pressure plate 314... During movement, the support plate 315 is pushed to slide outward away from the interior of the fixed frame 30 by the cooperation between the inclined planes. Then, the battery pack body 15 is lowered by a forklift, so that the support plate 315 extending out of the bearing frame 13 contacts the ground. Then, the forklift fork arm is disengaged from the bearing plate 16. At this time, the bearing plate 16 loses the position restriction of the positioning rod 241 and slides downward along the trajectory of the extension plate 17 under the action of gravity. The push plate 20 loses the upward displacement driven by the bearing plate 16 and no longer pushes the fixed plate 21. The torsion spring 221 releases its stored force to drive the fixed plate 21 to flip in the opposite direction and reset, loosening the fixation on the battery pack body 15. The operator can then directly remove the old battery pack body 15 from the bearing frame 13 and replace it with a new cascade battery pack body 15.

[0043] In summary, by connecting plate 312, unlocking plate 313 and pressing plate 314 move simultaneously, allowing support plate 315 to extend along the trajectory of fixed frame 30 during the process of positioning rod 241 disengaging from positioning plate 23, thereby facilitating the replacement of battery pack body 15 on carrier frame 13.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
