[0024] Please refer to Figure 1 , the present invention provides a technical solution: a self-service battery charging and swapping cabinet, including a charging and swapping cabinet body 1. A plurality of charging and swapping battery compartments 2 are arranged inside the charging and swapping cabinet body 1, and the charging and swapping battery compartments 2 are used for storing and charging batteries: Please refer to Figures 1 to 3 , an explosion-proof unit 3 is arranged inside each of the charging and swapping battery compartments 2. The explosion-proof units 3 are all rectangular pieces with a hollow interior. The explosion-proof unit 3 is used to block the impact generated by the explosion of the battery, so as to prevent the explosion impact from damaging the charging and swapping cabinet body 1 or other explosion-proof units 3, avoid the chain reaction of battery explosion, and at the same time block the spontaneous combustion of the battery to prevent the remaining spontaneous combustion flames from spreading to other batteries; Meanwhile, a connector 4 is provided on one side of the explosion-proof unit 3. The connector 4 is used to charge the battery. A charging head 5 is arranged inside the explosion-proof unit 3. The charging heads 5 are electrically connected to the charging and swapping cabinet body 1. The charging head 5 is used to supply power to the explosion-proof unit 3; Please refer to Figures 4 to 6 , and storage cavities 6 are arranged inside the left and right side walls of the explosion-proof unit 3. The storage cavities 6 are all arranged as rectangular groove cavities. High-pressure fire extinguishing media are filled inside the storage cavities 6. The high-pressure fire extinguishing media can effectively spray out from the storage cavities 6. A plurality of groups of external spray parts 7 are arranged on the upper ends of the side walls of the explosion-proof unit 3 at equal intervals corresponding to the storage cavities 6. The storage cavities 6 and the external spray parts 7 are used to extinguish fires when the battery catches fire. At the same time, the external spray parts 7 are all arranged as nozzles with the nozzles facing downwards. The plurality of groups of external spray parts 7 with the nozzles facing downwards can facilitate extinguishing fires at different positions; And a blocking component 8 is arranged on one side of each external spray part 7. The blocking component 8 all includes a blocking piece 9. The blocking piece 9 is arranged as a T-shaped rubber piece. The blocking pieces 9 are all located inside the external spray parts 7. The blocking pieces 9 located inside the external spray parts 7 can facilitate blocking the external spray parts 7 and prevent the external spray parts 7 from starting to spray the fire extinguishing media on the battery when there is no fire. Limiting pieces 10 are arranged on the outer sides of the blocking pieces 9. The limiting pieces 10 are all arranged as annular structures made of rubber. Annular clamping grooves are arranged inside the external spray parts 7 corresponding to the limiting pieces 10. The limiting pieces 10 are all located in the annular clamping grooves. The limiting pieces 10 cooperating with the annular clamping grooves inside the external spray parts 7 can facilitate restricting the blocking pieces 9 inside the external spray parts 7 and prevent the blocking pieces 9 from being pushed away from the external spray parts 7 by the high-pressure fire extinguishing media; Meanwhile, hook-shaped parts 11 are fixedly connected to the other sides of the blocking pieces 9. Pulling ropes 12 are fixedly connected to the other sides of the hook-shaped parts 11. The design of the pulling ropes 12 can pull the blocking pieces 9 outwards from inside the external spray parts 7 when the external spray parts 7 are needed to extinguish fires, so that the blocking of the external spray parts 7 by the blocking pieces 9 is released. Two groups of fixing rods 13 are arranged inside the upper ends of the explosion-proof unit 3 corresponding to the pulling ropes 12. One sides of the pulling ropes 12 are all located at the bottoms of the fixing rods 13. By arranging the fixing rods 13, the pulling direction of the pulling ropes 12 can be changed, which is convenient for better pulling the blocking pieces 9 out of the external spray parts 7; At the upper end of the explosion-proof unit 3, two sets of push grooves 14 are correspondingly arranged corresponding to the storage cavity 6. The push grooves 14 are all arranged as horizontal rectangular grooves. At the inner bottom of the push grooves 14, falling holes 15 are arranged. The widths of the falling holes 15 are all smaller than those of the push grooves 14. The bottoms of the falling holes 15 penetrate through the side walls of the explosion-proof unit 3. Push members 16 are movably arranged inside the push grooves 14. The push members 16 are all located above the falling holes 15. The falling holes 15 with widths smaller than those of the push grooves 14 can facilitate the movement of the push members 16 and prevent the push members 16 from falling during movement. On the side of the push members 16 away from the center of the explosion-proof unit 3, a plurality of elastic members 17 are fixedly connected. The elastic force of the plurality of elastic members 17 is greater than the resistance of the plugging member 9 to plug the external spraying member 7. A pull rope 12 is fixedly connected to the bottom of the push member 16. When fire extinguishing is required, the elastic members 17 push the push members 16 to move horizontally along the push grooves 14, so that the pull rope 12 pulls the plugging member 9 away from the inside of the external spraying member 7; And on the side of the push member 16 close to the center of the explosion-proof unit 3, two sets of heat-sensitive self-exploding members 18 are arranged. Since the heat-sensitive self-exploding members 18 are located between the push member 16 and the push groove 14, the two sets of heat-sensitive self-exploding members 18 arranged can increase the support for the push member 16. A liquid storage cavity 19 is arranged inside each of the heat-sensitive self-exploding members 18. The liquid storage cavity 19 is filled with a heat-expandable liquid. When the heat-expandable liquid encounters a fire, it can expand, causing the heat-sensitive self-exploding members 18 to self-explode and no longer restrict the push member 16. At the same time, the push grooves 14 arranged at the upper end of the explosion-proof unit 3 can effectively absorb the heat generated by the battery, facilitating the timely activation of the storage cavity 6 when a fire occurs; At the same time, on the side of the push member 16 close to the center of the explosion-proof unit 3, mounting holes one 20 are correspondingly arranged corresponding to the heat-sensitive self-exploding members 18. The mounting holes one 20 are all arranged as threaded holes. On the side walls of the push grooves 14, mounting holes two 21 are correspondingly arranged corresponding to the heat-sensitive self-exploding members 18. The mounting holes two 21 are all arranged as threaded holes. External threads are arranged on both sides of the heat-sensitive self-exploding members 18. The two sides of the heat-sensitive self-exploding members 18 are respectively screwed into the mounting holes one 20 and the mounting holes two 21. The screwing of the heat-sensitive self-exploding members 18 with the mounting holes two 21 and the mounting holes one 20 can limit the heat-sensitive self-exploding members 18 to prevent them from detaching. At the same time, it is convenient for timely replacement after fire extinguishing. At the same time, the heat-sensitive self-exploding members 18 are located above the falling holes 15, which can facilitate the timely cleaning of their fragments after self-explosion and avoid harming the staff during the subsequent installation of the heat-sensitive self-exploding members 18; Please refer to Figures 7 to 9, a rotating cavity 22 is provided inside the side wall of the explosion-proof unit 3 near the charging head 5. A first electrical connection member 23 is fixedly connected to the bottom of the rotating cavity 22, and the first electrical connection member 23 is electrically connected to the charging head 5. A second electrical connection member 24 is provided at the bottom of the rotating cavity 22, and the second electrical connection member 24 is electrically connected to the charging head 5. There is a gap between the first electrical connection member 23 and the second electrical connection member 24. The existence of this gap can facilitate the power-off of the explosion-proof unit 3 and the battery inside it in case of a fire; At the same time, a central shaft 25 is fixedly installed in the middle of the rotating cavity 22. One end of a torsion member 26 is fixedly connected to the outside of the central shaft 25. A rotating member 27 is sleeved outside the torsion member 26, and the other end of the torsion member 26 is fixedly connected to the rotating member 27. The torsion member 26 can drive the rotating member 27 to rotate with the central shaft 25 as the center. A first transmission member 28 is fixedly connected to the bottom of the rotating member 27. The first transmission member 28 is made of insulating material. The insulating first transmission member 28 can prevent current from being brought to other components. The docking member 29 is made of metal conductive material. The docking member 29 is located on one side of the first electrical connection member 23 and the second electrical connection member 24 and is in contact. The first electrical connection member 23 and the second electrical connection member 24 are electrically connected through the docking member 29. The wire connection between the docking member 29 and the first electrical connection member 23 and the second electrical connection member 24 can facilitate the charging of the battery in the explosion-proof unit 3 and at the same time facilitate the timely separation from the first electrical connection member 23 and the second electrical connection member 24 for power-off; And a second transmission member 30 is fixedly connected to the upper end of the rotating member 27. An activity groove 32 is provided at the upper end of the second transmission member 30. The activity groove 32 is a vertical groove. An activity member 33 is movably arranged inside the activity groove 32. The vertically arranged activity groove 32 can facilitate the movement of the activity member 33. A moving groove 31 is provided at the upper end of the rotating cavity 22 corresponding to the activity member 33. One side of the moving groove 31 is communicated with the pushing groove 14 in the corresponding direction. One side of the activity member 33 is fixedly connected to the pushing member 16 in the corresponding direction. The second transmission member 30 is provided with the activity member 33 at the upper end. The fixed connection between the pushing member 16 and the activity member 33 can drive the activity member 33 to move along the moving groove 31 when the pushing member 16 moves, so that the second transmission member 30 drives the first transmission member 28 to rotate with the central shaft 25 as the center, and further separates the docking member 29 from the first electrical connection member 23 and the second electrical connection member 24, so that the explosion-proof unit 3 is powered off.
[0025] In case of a fire, first, the heat-expandable liquid inside the heat-explosion self-destruction part 18 expands after being fumigated by the hot air generated by the fire, causing the heat-explosion self-destruction part 18 to explode. The heat-explosion self-destruction part 18 no longer restricts the pushing part 16, and the elastic part 17 pushes the pushing part 16 to move along the pushing groove 14 through its own elastic force. The pushing part 16 drives the pulling rope 12 to move, and the pulling rope 12 pulls the blocking part 9 out of the outer spraying part 7 through the hook 11, so that the blocking part 9 no longer restricts the outer spraying part 7. The high-pressure fire extinguishing medium stored in the storage cavity 6 is sprayed out from the outer spraying part 7 to extinguish the battery, reducing the economic losses caused by the spontaneous combustion of the battery in the charging and swapping cabinet body 1, and improving the safety performance of the charging and swapping cabinet body 1. At the same time, when the pushing part 16 moves along the pushing groove 14, a group of pushing parts 16 drive the movable part 33 to move along the moving groove 31. The movable part 33 drives the transmission part one 28 to rotate around the rotating part 27 through the transmission part two 30, so that the docking part 29 is separated from the first power connection part 23 and the second power connection part 24, and the explosion-proof unit 3 is powered off.
