DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] Example: Figure 1-Figure 13As shown, the present invention provides a technical solution for an energy storage battery cabinet that can automatically access a battery pack, including an energy storage battery cabinet structure 1 and a controller 3. The energy storage battery cabinet structure 1 includes a cabinet body 11, a door body 12, a partition frame 14 and six battery packs 15. Seven sockets 17 are fixedly installed on the partition frame 14. Two metal plates 19 are fixedly installed on the side of the battery pack 15 away from the socket 17. A battery pack access structure 2 is installed on the cabinet body 11. The battery pack access structure 2 includes a sealing plate 228 arranged on the side of the battery pack 15 away from the socket 17, and a transmission plate 228 fixedly connected to the side of the sealing plate 228 away from the battery pack 15. Plate component seven 231, two transmission plate components eight 233 fixedly connected at the bottom of one side of transmission plate component seven 231, and two automatic access components, the automatic access components include a vertical box 21, a square box 22, a pneumatic cylinder one 26, a transmission plate component one 27, a transmission plate component three 210, four connecting rods 222 inserted on the transmission plate component three 210 and two transmission plate components five 224 inserted on the transmission plate component three 210, two electromagnets one 230 are fixedly installed on the sealing plate 228, two square slots 232 are provided on the transmission plate component seven 231, and a plurality of circular slots 234 are provided on one side of the transmission plate component eight 233.

[0023] Specifically, the door body 12 is hingedly installed inside the cabinet body 11, and the door body 12 is opened and closed to facilitate construction operations inside the cabinet body 11. A door handle 13 is fixedly installed on the side of the door body 12 away from the battery pack 15, and the door handle 13 serves as a fulcrum for operating the door body 12; a partition frame 14 is fixedly installed inside the cabinet body 11, and the partition frame 14 divides the inside of the cabinet body 11 into seven spaces. The space at the top is used to install power distribution equipment, and the remaining two spaces are used to install battery packs 15; seven sockets 17 are distributed on a U-shaped path, and two connectors are installed on the side of the battery pack 15 close to the socket 17 16. The connector 16 is arranged inside the adjacent sockets 17. The seven sockets 17 connect the six battery packs 15 in series. When the battery pack 15 needs to be replaced, it is only necessary to control the battery pack 15 to be horizontally away from the socket 17 so that the connector 16 leaves the inside of the socket 17. This can disconnect the battery pack 15 from the internal circuit of the energy storage battery cabinet, and can quickly separate the battery pack 15 from the energy storage battery cabinet. The staff can complete the separation and disassembly of the battery pack 15 without operating the circuit of the energy storage battery cabinet, thereby reducing safety hazards and meeting the working scenario of disassembling the battery pack 15 in the event of accidental leakage.

[0024] Two reserved grooves 18 are provided at the bottom of the battery pack 15, and the reserved grooves 18 are formed on the partition frame 14. Two transmission plate members 8 233 fixedly installed on the transmission plate member 7 231 are provided on one side of the battery pack 15 and are respectively inserted into the two reserved grooves 18. The two transmission plate members 8 233 and the bottom of the outer shell of the battery pack 15 are both lifted. The sealing plate 228 fixedly connected to the transmission plate member 7 231 near one side of the battery pack 15 is inserted on the cabinet 11, and two electromagnets 1 230 are fixedly connected to one side of the sealing plate 228. The metal plate 19 provided on one side of the electromagnet 1 230 is fixedly installed on the battery pack 15, so that the sealing plate 228 and the transmission plate member 7 231 form a sealing protection plate corresponding to the battery pack 15, so that a battery pack 15 will not damage the sealing structure of the other battery packs 15 during the disassembly process, thereby reducing the impact on the other battery packs 15 and reducing safety hazards.

[0025] When the battery pack 15 needs to be disassembled and replaced, the number of the battery pack 15 to be replaced is input on the controller 3 installed on the vertical box 21, and the controller 3 controls the corresponding automatic access component to work: First, the two square grooves 229 fixedly installed on the sealing plate 228 on one side of the corresponding battery pack 15 work, and the square grooves 229 are adsorbed and fixed together with the iron metal plate 19 fixedly installed on the battery pack 15 by magnetic force, and the bottom of the battery pack 15 is supported by the two transmission plates 8 233 fixedly installed on the transmission plate 7 231 fixed on the sealing plate 228, so the battery pack 15 can move synchronously with the transmission plate 7 231; At the same time, the forward and reverse motor 216 works forward, and the working forward and reverse motor 216 drives the transmission horizontal shaft 214 fixed at the conveying end and the take-up frame 213 fixed outside the transmission horizontal shaft 214 to rotate, and one end of the wire rope 211 is fixedly connected to the take-up frame 213, and the wire rope 211 is partially wrapped around the outside of the take-up frame 213. Fig.13 As shown, at this time, the take-up frame 213 rotates in the unwinding direction, and the wire rope 211 is unwound; when the wire rope 211 fixedly installed on the top of the transmission plate 3 210 is unwound, the transmission plate 3 210 loses its limit and can move downward under the action of gravity; and a plurality of transmission metal rods 29 are fixedly connected to the bottom of the transmission plate 28, and the bottom ends of the plurality of transmission metal rods 29 all penetrate the transmission plate 3 210, as shown in FIG. Fig.10 As shown, under the limit of the multiple transmission metal rods 29, the transmission plate member 3 210 can only move up and down; when the transmission plate member 3 210 moves down to the preset position on the side of the battery pack 15 that needs to be replaced, the forward and reverse motors 216 stop working; Subsequently, the pneumatic cylinder three 226 fixedly installed on the transmission plate three 210 works. Since the transmission plate six 225 is fixedly installed between the two transmission plates five 224 inserted on the transmission plate three 210, the transmission plate six 225 and the piston end of the pneumatic cylinder three 226 are fixedly installed together; at this time, the two transmission plates five 224 correspond one to one with the two square slots 232 opened on the transmission plate seven 231 on the side of the battery pack 15 to be disassembled, so the working and contracted pneumatic cylinder three 226 drives the two transmission plates five 224 to move through the transmission plate six 225, and finally the transmission plate five 224 is inserted into the corresponding transmission plate eight 233; Subsequently, the pneumatic cylinder 1 26 works, and the pneumatic cylinder 1 26 extends to push the transmission plate 1 27, and the transmission plate 1 27 drives the fixedly connected transmission plate 2 28 to move. Since the bottom ends of the multiple transmission metal rods 29 fixedly connected to the bottom of the transmission plate 28 are all equipped with support rollers 227, the movement resistance of the transmission plate 2 28 is relatively small. The multiple transmission metal rods 29 penetrate the transmission plate 3 210, so the transmission metal rods 29 drive the transmission plate 3 210 to move, and the transmission plate 3 210 is inserted into the The two transmission plates 5 224 drive the transmission plate 7 231 to move, so that the transmission plate 7 231 drives the battery pack 15 to move to the outside of the cabinet 11 under the cooperation of the sealing plate 228, the electromagnet 1 230, the transmission plate 8 233, the metal plate 19 and other structures. When the multiple circular slots 234 opened on the pneumatic cylinder 223 move to the outside of the cabinet 11, the pneumatic cylinder 1 26 stops working. At this time, one end of the transmission plate 8 233 is still arranged inside the cabinet 11 and supported by the partition frame 14; Subsequently, the pneumatic cylinder 223 fixedly installed on the transmission plate 3 210 is controlled to work. Since one end of the pneumatic cylinder 223 is fixedly connected to the transmission plate 4 221, and the multiple plug-in rods 222 fixedly connected to the transmission plate 4 221 all penetrate the transmission plate 3 210, at this time, the multiple plug-in rods 222 correspond to the multiple circular slots 234 one by one, and the pneumatic cylinder 223 drives the plug-in rods 222 to be inserted into the corresponding circular slots 234 through the transmission plate 4 221, so that the multiple plug-in rods 222 support the transmission plate 8 233; Subsequently, one of the transmission metal rods 29 is controlled to work with the electromagnet 236 sleeved on the outside, and the electromagnet 236 fixedly connected to the transmission plate 3 210 works by adsorbing and working together with the iron transmission metal rod 29 through magnetic force. At this time, the up and down movement of the transmission plate 3 210 is restricted, and the transmission plate 3 210 cannot be displaced. The pneumatic cylinder 1 26 is controlled to continue working to move the transmission plate 8 233 and the battery pack 15. The transmission plate 7 231 and the transmission plate 8 233 are supported by the two transmission plate 5 224 and a plurality of plug-in rods 222. While the pneumatic cylinder 1 26 is working, the forward and reverse motor 216 continues to work forward, and the wire rope 211 is unwound to meet the movement needs of the transmission plate 3 210. When the battery pack 15 and the transmission plate eight 233 completely leave the cabinet 11, the weight of the battery pack 15 acts on the transmission plate eight 233 and the transmission plate seven 231, the electromagnet two 236 stops working, the transmission plate three 210 can move up and down, the forward and reverse motor 216 continues to work forward, the wire rope 211 is unwound, and the transmission plate three 210 moves downward under the limitation of multiple transmission metal rods 29, the battery pack 15 moves downward, and finally the transmission plate three 210 moves down to the bottom position, the battery pack 15 is located on the ground, the forward and reverse motor 216 stops working, and the brake 215 sleeved on the outside of the transmission horizontal shaft 214 works. The brake 215 works to limit the transmission horizontal shaft 214, so that the wire rope 211 remains taut and the force on the forward and reverse motor 216 is reduced. At this time, the automatic access component completes the disassembly work, and the automatic access component enters the pause state.

[0026] In summary, the staff only needs to preset the CNC program inside the controller 3 to quickly separate the battery pack 15 from the cabinet 11 when needed. The automatic access component can automatically and quickly transport the battery pack 15 that needs to be replaced to a location on the ground. The staff does not need to disassemble, pull, or carry the heavy battery pack 15 at a high place, thereby reducing the physical input of the staff, and the staff does not need to operate the interior of the faulty energy storage battery cabinet, thereby reducing safety hazards.

[0027] The staff takes down the battery pack 15 supported by the transmission plate 7 231 and the two transmission plate 8s 233, and moves the new battery pack 15 to the top of the transmission plate 8 233. Since the shape of one side of the sealing plate 228 is the same as the shape of one end of the metal plate 19 for mounting the battery pack 15, the position of the battery pack 15 can be preset after aligning and fitting one end of the battery pack 15 with the sealing plate 228.

[0028] The controller 3 controls the automatic access component to access the battery pack 15: First, the controller 3 controls the electromagnet 1 230 to work to adsorb and fix the metal plate 19 fixed on the battery pack 15; Subsequently, the brake 215 is controlled to stop working, the transmission horizontal shaft 214 loses its limit, and the forward and reverse motors 216 are controlled to work in reverse. The forward and reverse motors 216 drive the transmission horizontal shaft 214 and the take-up rack 213 fixedly sleeved on the outside of the transmission horizontal shaft 214 to reverse, so that the take-up rack 213 rotates to rewind the wire rope 211. The wire rope 211 pulls the transmission plate 3 210, the transmission plate 7 231 and the transmission plate 8 233, and the battery pack 15 supported by the transmission plate 7 231 and the transmission plate 8 233 to move upward. When the transmission plate 7 231 is reset to the upper and lower positions, the forward and reverse motors 216 stop working, and the brakes 215 work to limit the transmission horizontal shaft 214. Subsequently, the pneumatic cylinder 1 26 contracts for a certain distance, causing the transmission plate 1 27 fixedly connected to the pneumatic cylinder 1 26 to move for a certain distance. The transmission plate 1 27 drives the transmission plate 3 210 to move for a certain distance inside the vertical box 21 through the transmission plate 2 28 fixedly connected to the bottom and the plurality of transmission metal rods 29 fixedly connected to the top of the transmission plate 28. At this time, the transmission plate 8 233 is partially inserted into the reserved groove 18 provided on the partition frame 14. Then, the second pneumatic cylinder 223 works and extends, and the second pneumatic cylinder 223 drives the multiple plug-in rods 222 to move through the fourth transmission plate 221, so that the multiple plug-in rods 222 leave the inside of the circular slot 234; Then, the pneumatic cylinder 1 26 works and contracts, so that the battery pack 15 completely enters the cabinet 11 and is supported by the partition frame 14, and the connector 16 on the battery pack 15 is inserted into the corresponding socket 17; Then, the electromagnet 1 230 stops working, and the pneumatic cylinder 3 226 works to push the transmission plate 6 225 to move, so that the transmission plate 5 224 leaves the inside of the square slot 232, and the forward and reverse motor 216 works in the reverse direction again, so that the transmission plate 3 210 moves up and resets.

[0029] In summary, the battery pack 15 can be quickly lifted to the corresponding height and pushed into the cabinet 11, reducing the safety hazards caused by the staff lifting and pushing the battery pack 15, and avoiding the change in force direction caused by the staff manually operating the battery pack 15 and colliding with the partition frame 14 inside the cabinet 11, reducing the possibility of damage to the battery pack 15 due to operational errors, and avoiding the impact of the partition frame 14 on the safety of the remaining battery packs 15.

[0030] In addition, such as Figure 8 As shown, two square grooves 229 are opened on one side of the sealing plate 228, and two electromagnets 230 are respectively arranged inside the two square grooves 229. The electromagnet 230 is installed inside the square groove 229 so that one end of the sealing plate 228 can be tightly attached to the battery pack 15, so that the sealing plate 228 can serve as a reference for positioning the battery pack 15.

[0031] In addition, such as Figure 1 As shown, the square box 22 is fixedly installed on the top of the vertical box 21, and the plug-in rod 222 and the vertical box 21 form a storage outer box to store the automatic access components, protect the automatic access components, and reduce the possibility of staff contacting the automatic access components.

[0032] In addition, such as Figure 5 and Fig.12As shown, two limit frames 217 are arranged inside the square box 22, and a guide frame 218 inserted on the limit frame 217 is rotatably connected to a plurality of drag reducing rollers 219. The two guide frames 218 are fixedly connected to the transmission plate 27. The two guide frames 218 provide limit support for the movement of the transmission plate 27 to prevent the tilting force received by the transmission plate 27 during the process of being pushed by the pneumatic cylinder 26 from directly acting on the pneumatic cylinder 26, thereby protecting the pneumatic cylinder 26, and the plurality of rotating drag reducing rollers 219 play a role in reducing the movement resistance of the guide frame 218, thereby reducing the wear of the guide frame 218 and the transmission plate 27.

[0033] In addition, such as Figure 5 and Fig.12 As shown, the forward and reverse motor 216 is fixedly connected to one of the limit frames 217, and a fixed vertical rod 220 is fixedly installed between the top of the other limit frame 217, the top of the forward and reverse motor 216, the top of the brake 215 and the top of the pneumatic cylinder 26 and the square box 22, so that the automatic access component and the square box 22 move synchronously.

[0034] In addition, such as Figure 5 and Fig. 9 As shown, an outer groove 235 is opened on one side of the square box 22, and the outer groove 235 provides a channel for the movement of the transmission plate 27, and the changing roller 212 arranged inside the outer groove 235 is fixedly connected to the transmission plate 27, and the changing roller 212 supports and changes the direction of the wire rope 211. The changing roller 212 prevents the wire rope 211 from directly contacting the square box 22, thereby reducing the wear rate of the wire rope 211 during operation.

[0035] In addition, such as Figure 1 and Figure 2 As shown, two connecting transverse plates 23 are fixedly installed between the two square boxes 22, and a plurality of circular holes 25 are opened on the top of the connecting transverse plates 23. Internally threaded parts 110 are inserted into the circular holes 25 and fixedly connected to the cabinet body 11. After the T-bolts 24 connected to the internal threads of the internally threaded parts 110 are rotated and removed, the up and down movement of the connecting transverse plates 23 can be freed from limit, and the fixation between the battery pack access structure 2 and the cabinet body 11 can be removed. The battery pack access structure 2 can be disassembled and installed on other energy storage battery cabinet structures 1 with the same specifications, or different CNC programs can be preset in the controller 3 fixedly installed on one side of the vertical box 21 according to different energy storage battery cabinet structures 1, so as to meet the needs of automatic disassembly and access of battery packs 15 in multiple energy storage battery cabinet structures 1.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
