Description

Technical Field

[0001] This invention belongs to the field of battery charging equipment technology, specifically relating to a high-voltage isolated centralized charging cabinet and its charging method. Background Technology

[0002] With the continuous development of technology, batteries are being used more and more widely in various fields, and the demand for battery charging is also increasing. High-voltage isolated centralized charging cabinets, as a highly efficient and convenient battery charging device, have been widely used in industrial production, logistics warehousing, and electric vehicle charging stations. However, existing high-voltage isolated centralized charging cabinets still have some problems in their use.

[0003] Problems with existing technology:

[0004] However, in actual use, existing high-voltage isolation centralized charging cabinets have exposed a series of problems that urgently need to be solved. Battery charging is a complex process, which is affected by a variety of factors such as the uneven quality of the batteries themselves and the changes in the temperature, humidity and ventilation conditions of the charging environment. Serious safety accidents such as battery fires occur from time to time. Once a fire occurs in the charging chamber, the fire can spread very quickly due to the relatively enclosed space and dense electrical equipment inside the charging cabinet. This will not only cause serious damage to the charging cabinet, but may also trigger a chain of failures in the surrounding equipment, resulting in huge economic losses and safety hazards.

[0005] To address this issue, some existing charging cabinets have installed fire extinguishing devices inside the charging chamber. However, the fire extinguishing process is not instantaneous. From the detection of the fire to the activation of the fire extinguishing equipment and the successful extinguishing of the fire, there is still enough time for the fire to cause irreversible burning damage to the precision components inside the charging chamber. In addition, the extinguishing agents sprayed by the fire extinguishing devices are often corrosive or sticky, making the cleanup work extremely tedious, time-consuming, and labor-intensive. It may also cause secondary damage to the internal structure of the charging cabinet, affecting the subsequent normal operation of the equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a high-voltage isolated centralized charging cabinet and its charging method, which can quickly push a burning battery out of the charging chamber, prevent the battery from burning and exploding in the charging chamber, and provide a reliable guarantee for the safety of the entire charging environment.

It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0050] Example 1

[0051] like Figures 1-11 As shown, a high-voltage isolated centralized charging cabinet includes a charging cabinet body 1, and multiple charging chambers 2 are equidistantly arrayed on one side of the charging cabinet body 1.

[0052] A first mounting groove 3 is provided on the other side of the charging cavity 2, and a disengagement mechanism 4 is provided inside the first mounting groove 3;

[0053] The extension of the electric push rod 416 drives the top plate 411 to move, causing the inclined block 45 to retract into the first insertion slot 44. The electric push rod 416 continues to extend, at which time it drives the square insertion rod 42 to move to one side. The push plate 43 cooperates with the door opening mechanism 6 to move the bottom of the box door 63 to one side and open it. At the same time, it pushes the burning battery to separate from the charging chamber 2. The electric push rod 416 retracts and resets. The second spring 412 drives the square insertion rod 42 to reset and move, and drives the push plate 43 back to the initial position.

[0054] A receiving mechanism 5 is provided on one side of the charging cabinet 1 to receive batteries that fall from the charging chamber 2.

[0055] The receiving mechanism 5 includes a processing box 55, and a buffer mechanism 7 is provided inside the processing box 55;

[0056] During the process of the battery falling into the processing box 55, the battery first contacts multiple elliptical buffer rings 76, the elliptical buffer rings 76 deform, and initially buffer the battery. The second slider 73 slides with damping and causes the fourth spring 74 to compress and deform, providing secondary buffering for the battery. After the battery enters the processing box 55, the bottom and the elliptical buffer rings 76 around the battery form a limiting groove that matches the battery. At the same time, the battery is in close contact with the elliptical buffer rings 76 around it, and the battery is fixed by the friction between the two.

[0057] A snap-fit ​​assembly 8 is provided on the inner side of the first mounting slot 3.

[0058] like Figures 1-10As shown, the disengagement mechanism 4 includes a guide hole 41 disposed inside the charging cavity 2 and communicating with the first mounting groove 3. A square plug rod 42 is inserted into the guide hole 41. One end of the square plug rod 42 is located in the charging cavity 2 and is fixedly engaged with a push plate 43. A notch is provided on the bottom side of one side of the push plate 43. A charging plug 11 for connecting to the battery is provided on the inner side of the charging cavity 2 corresponding to the notch. A first plug groove 44 is formed on the top of the square plug rod 42 and located in the first mounting groove 3. An inclined plate block 45 for limiting the square plug rod 42 is slidably installed inside the first plug groove 44. A first spring 46 fixed to the bottom of the inclined plate block 45 is fixed to the inner bottom wall of the first plug groove 44. A groove 410 is formed on one end of the square plug rod 42. The inner side of the groove 410 is... A connecting hole communicating with the first insertion slot 44 is provided. A first guide rod 47 is inserted into the connecting hole. One end of the first guide rod 47 is located in the first insertion slot 44 and a limit slider 48 is provided. The outer wall of the inclined block 45 is provided with an inclined groove 49 that is slidably connected to the limit slider 48. One end of the first guide rod 47 is located in the groove 410 and fixed to the top plate 411. A second spring 412 connected to the square insertion rod 42 is provided on the inner side of the first mounting groove 3. A first lead screw 413 is provided on both inner sides of the first mounting groove 3. A first moving block 414 is threaded onto the outer wall of the first lead screw 413. A first electric slide rail 415 is provided between the outer walls of the two first moving blocks 414. An electric push rod 416 is provided at the output end of the first electric slide rail 415.

[0059] The receiving mechanism 5 includes a second lead screw 51 disposed on both sides of the outer wall of the charging cabinet 1. A second moving block 53 is threaded onto the outer wall of the second lead screw 51. A second electric slide rail 54 is disposed between the outer walls of the two second moving blocks 53. A processing box 55 is disposed at the output end of the second electric slide rail 54. The processing box 55 is a box with openings on the top and one side. An adjusting plate 58 is rotatably mounted at one side opening of the processing box 55. A first hydraulic cylinder 56 is rotatably mounted on both sides of the processing box 55. A second connecting rod 57 is rotatably mounted on the output shaft of the first hydraulic cylinder 56. The other end of the second connecting rod 57 is disposed at the rotatable connection of the adjusting plate 58.

[0060] The bottom of the charging cabinet 1 is provided with a second mounting groove. A belt 52 is provided between the bottom ends of the first lead screw 413 and the second lead screw 51 and located in the second mounting groove. A drive shaft 18 is provided inside the second mounting groove and between the two first lead screws 413. The two ends of the drive shaft 18 are connected to the first lead screw 413 through the cooperation of worm gear and worm. A motor 17 is provided inside the second mounting groove, and the output shaft of the motor 17 is connected to the drive shaft 18 through the cooperation of worm gear and worm.

[0061] The outer wall of the charging cabinet 1 is provided with multiple slanted panels 9, and the slanted panels 9 are located on the upper and lower sides of the charging cavity 2.

[0062] According to the above structure, when a fire is detected in the battery inside the charging chamber 2 or when smoke is generated, the motor 17 drives the first lead screw 413 to rotate via the transmission shaft 18. The first lead screw 413 drives the first moving block 414 to move. The first moving block 414 drives the first electric slide rail 415 to move up and down. The first electric slide rail 415 drives the electric push rod 416 to move left and right, so that the electric push rod 416 moves to the position of the top plate 411 corresponding to the burning charging chamber 2. The electric push rod 416 is then activated. The electric push rod 416 first pushes the top plate 411. The top plate 411 drives the first guide rod 47 to move. The first guide rod 47 pushes the limit position. The slider 48 engages with the inclined groove 49, causing the inclined plate block 45 to retract into the first insertion groove 44. The electric push rod 416 continues to extend, causing the square insertion rod 42 to move. The square insertion rod 42 causes the push plate 43 to move, and the push plate 43 pushes the battery to move. At the same time, the belt 52 is engaged, causing the second lead screw 51 to move. The second lead screw 51 causes the second moving block 53 to move. The second moving block 53 causes the second electric slide rail 54 to move up and down. The second electric slide rail 54 causes the processing box 55 to move left and right, so that the processing box 55 is moved below the charging chamber 2 where the fire occurred, making it convenient to catch the burning battery.

[0063] The structure is simple and makes it easy to push the burning battery out of the charging chamber 2, preventing the battery from burning and exploding inside the charging chamber 2, thus providing a reliable guarantee for the safety of the entire charging environment. At the same time, this design also provides a good foundation for preventing the spread of the subsequent impact of battery safety accidents, preventing the fire from spreading to other batteries or charging equipment in the vicinity, thereby maintaining the stability and integrity of the entire charging system.

[0064] The first hydraulic cylinder 56 is activated, which drives the second connecting rod 57 to move. The second connecting rod 57 drives the adjusting plate 58 to rotate near the charging chamber 2, tilting it to contact the inclined panel 9 on the charging cabinet 1. The structure is simple, allowing the fallen battery to fall down the adjusting plate 58 into the processing box 55, avoiding excessive impact from the battery falling too fast, preventing the battery from exploding if it catches fire, and improving the safety of the equipment.

[0065] The inclined plate 45, when not in use, can be locked in one side of the guide hole 41 to stably fix the push plate 43 and the square plug rod 42, thus improving the stability of the equipment. When the square plug rod 42 is reset, the second spring 412 causes the square plug rod 42 to move, and the inclined plate on the inclined plate 45 contacts the guide hole 41 and is squeezed by the inside of the guide hole 41, retracting into the first plug groove 44 until the inclined plate 45 moves out of the guide hole 41 and is locked in one side of the guide hole 41 again.

[0066] like Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, the door opening mechanism 6 includes guide rails 64 disposed on the outer wall of the charging cabinet 1 and located on both sides of the charging cavity 2. A first slider 65 is slidably mounted on the outer wall of the guide rails 64. A first mounting plate 66 is rotatably mounted between the outer walls of the first slider 65. A torsion spring is provided at the rotatable connection between the first mounting plate 66 and the first slider 65. A first push rod 61 is fixed on both sides of the push plate 43. A first guide groove 62 is opened on both inner sides of the charging cavity 2 and slidably connected to the first push rod 61. A door 63 is rotatably mounted between one end of the two first push rods 61 and outside the first guide groove 62 for sealing the charging cavity 2. A latch is provided on one side of the top of the door 63. A lock hole is provided on the outer wall of the first mounting plate 66 to cooperate with the latch. A third spring 67 is provided on the top of the first slider 65 for automatic reset movement of the first slider 65.

[0067] According to the above structure, when the push plate 43 pushes the battery to move, the push plate 43 pushes the first push rod 61 to move. The first push rod 61 pushes the bottom of the box door 63 to one side, and at the same time, the top of the box door 63 drives the first mounting plate 66 to rotate and move downward, so that the bottom of the box door 63 opens and the burning battery falls into the processing box 55 below. When the push plate 43 returns to its original position, it drives the first push rod 61 to retract, and the first push rod 61 drives the box door 63 to return to its original position and close. When the box door needs to be opened for battery charging, the latch is separated from the lock hole, and the box door 63 can be rotated to one side to open it. The cooperation between the first slider 65 and the guide rail 64 improves the stability of the movement of the first mounting plate 66. The third spring 67, when the top of the box door 63 separates from the first mounting plate 66, keeps the first mounting plate 66 at the top of the guide rail 64 through the elastic force of the third spring 67, which facilitates the opening and closing of the box door 63 and improves the stability of the equipment.

[0068] like Figures 10-11 As shown, the buffer mechanism 7 includes a second insertion slot 71 disposed at the bottom of the processing box 55 and distributed in an equidistant array. A second guide groove 72 is provided at the bottom of the second insertion slot 71. A second slider 73 slides up and down inside the second guide groove 72 with damping. A fourth spring 74 is provided at the bottom of the second slider 73 and fixed to the bottom of the second guide groove 72. A connecting rod 75 is inserted into the second insertion slot 71, and the bottom of the connecting rod 75 is threadedly connected to the top of the second slider 73. A plurality of elliptical buffer rings 76 are provided at the top of the connecting rod 75 along the circumferential direction. A third insertion slot 77 is provided at the top of the connecting rod 75. A first insertion rod 79 is fixedly connected to the top of the elliptical buffer ring 76 with damping sliding inside the third insertion slot 77. A plurality of leaf springs 78 connected to the inner side of the elliptical buffer ring 76 are fixed on the outer surface of the first insertion rod 79. An anti-slip protrusion 710 is provided on the outer surface of the elliptical buffer ring 76.

[0069] According to the above structure, when the burning battery falls into the handling box 55, it first contacts the elliptical buffer ring 76. The top of the elliptical buffer ring 76 is impacted and compressed, causing deformation. Then, in conjunction with the first insertion rod 79, the first insertion rod 79 slides with damping within the third insertion groove 77. The leaf spring 78 is also stretched, providing initial cushioning for the battery and preventing it from rebounding when it hits the bottom, thus avoiding damage or explosion and improving safety. When the elliptical buffer ring 76 is impacted, part of the impact force is transmitted to the connecting rod 75, which in turn transmits it to the second slider 73, causing the second slider 73 to slide with damping within the second guide groove 72. At the same time, the fourth spring is compressed. 74. The fourth spring 74 deforms, providing secondary cushioning for the burning battery and further preventing excessive impact on the battery, thus reducing the risk of explosion. In addition, after falling to the bottom of the treatment box 55, the elliptical buffer ring 76 that is not pressed by the battery and the pressed elliptical buffer ring 76 form a limiting groove that matches the battery. The anti-slip protrusions 710 on the side walls of the elliptical buffer ring 76 located around the battery rub against the battery, which can limit and fix the battery, facilitating subsequent fire extinguishing of the battery and increasing the practicality of the equipment. The leaf spring 78 facilitates the deformation and reset of the elliptical buffer ring 76. The elliptical buffer ring 76 is made of spring steel and is integrally pressed into an elliptical ring structure.

[0070] like Figures 9-10 As shown, a baffle is provided on one side of the top of the treatment box 55, and the top of the baffle is bent to one side. A fire extinguishing tank 12 is provided at the bottom of the treatment box 55. A fire extinguishing nozzle 14 for extinguishing battery fire is provided on one side of the baffle. The fire extinguishing nozzle 14 and the fire extinguishing tank 12 are connected to each other through a fire extinguishing pipe. A fire extinguishing pump 13 connected to the fire extinguishing pipe is provided on the outer wall of the treatment box 55.

[0071] According to the above structure, when a burning or smoking battery falls into the treatment box 55, the fire extinguishing pump 13 is activated to deliver the extinguishing agent in the fire extinguishing tank 12 to the fire extinguishing nozzle 14, and spray it onto the battery from the fire extinguishing nozzle 14 to extinguish the fire.

[0072] The top of the charging chamber 2 is equipped with a sensor 10 for detecting battery fire. The sensor 10 includes a flame detection sensor, a smoke detection sensor, and a temperature sensor. The first mounting slot 3 contains a battery 16 that is electrically connected to the sensor 10.

[0073] Based on the above structure, the sensor 10 is installed to facilitate the detection of whether the battery in the charging chamber 2 is smoking or has a tendency to catch fire, so as to facilitate timely control and prevent the spread of fire, thereby improving the safety of equipment use. The battery 16 is electrically connected to the first electric slide rail 415, the second electric slide rail 54, the electric push rod 416, the first hydraulic cylinder 56, the fire extinguishing pump 13, and the motor 17. The structure is simple. Even if the charging cabinet 1 is disconnected from the external power supply due to a short circuit or fire, these mechanisms that can extinguish the fire on the battery can still continue to work, further improving the safety of equipment use.

[0074] Working principle: When a fire or smoke is detected in the battery inside the charging chamber 2, the motor 17 starts, driving the first lead screw 413 to rotate via the transmission shaft 18. The first lead screw 413 drives the first moving block 414 to move, which in turn drives the first electric slide rail 415 to move up and down. The first electric slide rail 415 then drives the electric push rod 416 to move left and right, moving the electric push rod 416 to the position of the top plate 411 corresponding to the burning charging chamber 2. The electric push rod 416 is then activated, pushing the top plate 411, which in turn drives the first guide rod 47 to move. When the first guide rod 47 pushes the limiting slider 48 to engage with the inclined groove 49, the inclined plate block 45 retracts into the first insertion groove 44. The electric push rod 416 continues to extend, moving the square insertion rod 42. The square insertion rod 42 moves the push plate 43, which in turn moves the battery. Simultaneously, as the motor 17 drives the first lead screw 413 to rotate, the belt 52 drives the second lead screw 51 to move. The second lead screw 51 moves the second moving block 53, which in turn moves the second electric slide rail 54 up and down. The second electric slide rail 54 then moves the processing box 55. The device moves left and right, moving the processing box 55 below the charging chamber 2 where the fire occurred. Simultaneously, the push plate 43 moves the battery and pushes the first push rod 61, which in turn moves the bottom of the box door 63 to one side. The top of the box door 63 causes the first mounting plate 66 to rotate and move downwards, opening the bottom of the box door 63 and allowing the burning battery to fall into the processing box 55 below. The first hydraulic cylinder 56 is activated, moving the second connecting rod 57. The second connecting rod 57 then rotates the adjusting plate 58 near the charging chamber 2, tilting it relative to the inclined panel 9 on the charging cabinet 1. The contact allows the fallen battery to fall along the adjusting plate 58 into the processing box 55. After the burning battery falls into the processing box 55, it first contacts multiple elliptical buffer rings 76. The elliptical buffer rings 76 deform, providing initial cushioning for the battery. The second slider 73 provides damping sliding, and the fourth spring 74 is compressed and deformed, providing secondary cushioning for the battery. At the same time, the battery is in close contact with the elliptical buffer rings 76 around it, and the battery is fixed by the friction between the two. The fire pump 13 is activated to deliver the fire extinguishing agent in the fire extinguishing tank 12 to the fire extinguishing nozzle 14, and spray it from the fire extinguishing nozzle 14 onto the battery for fire extinguishing.

[0075] After the battery fire is extinguished, the equipment needs to be reset. The electric push rod 416 retracts and resets, the second spring 412 drives the square plug rod 42 to reset and move, and drives the push plate 43 back to the initial position. The push plate 43 drives the first push rod 61 to retract, and the first push rod 61 drives the box door 63 to reset and close. The first slider 65 returns to the initial position under the action of the third spring 67, the first mounting plate 66 also returns to the initial position, and the adjusting plate 58 returns to the initial position under the action of the first hydraulic cylinder 56. Then the extinguished battery can be taken out of the treatment box 55 to prepare for the next charging operation.

[0076] Example 2

[0077] like Figures 12-14 As shown, the snap-fit ​​assembly 8 includes a second mounting plate 81 disposed inside the first mounting groove 3 and located on one side of the guide hole 41. A first circuit breaker 814 is disposed on one side of the second mounting plate 81, and a third lead screw 82 is disposed on one side of the second mounting plate 81. A third moving block 83 is threadedly connected to the outer wall of the third lead screw 82. Pressure plates 84 are disposed on the outer walls of both the third moving block 83 and the second mounting plate 81. Positioning tubes 85 are disposed on the opposite outer walls of the two pressure plates 84. A conductive contact 811 is slidably inserted into the inside of the positioning tube 85. A sixth spring 812 connected to the conductive contact 811 is disposed on the inner side of the positioning tube 85. A movable plate 86 is slidably mounted on one side of the second mounting plate 81. The wall has a third mounting groove, and a toothed plate 87 is provided on the inner side of the third mounting groove. The bottom end of the third lead screw 82 is located in the third mounting groove and is provided with a gear 88 that meshes with the toothed plate 87. The outer wall of the second mounting plate 81 is provided with a fifth spring 89 that is connected to the moving plate 86. A second push rod 810 is fixed on one side of the moving plate 86. The first circuit breaker 814 has positioning holes 815 on both sides that cooperate with the positioning tube 85. The inner wall of the positioning hole 815 is provided with a conductive plug groove 816 that is electrically connected to the conductive contact 811. The outer wall of the second mounting plate 81 is provided with a limiting plate 813 for limiting the third moving block 83. The inner side of the first mounting groove 3 is provided with a second circuit breaker 15 for cutting off the external power supply.

[0078] According to the above structure, when installing the first circuit breaker 814, the positioning hole 815 at the bottom of the first circuit breaker 814 is aligned with the positioning tube 85 on the bottom of the second mounting plate 81 and inserted, so that the conductive contact 811 enters the conductive insertion groove 816 in the positioning tube 85, so that the conductive insertion groove 816 and the conductive contact 811 can make electrical contact and conduct electricity. Then, the moving plate 86 is pushed to one side by the second push rod 810. The moving plate 86 drives the toothed plate 87 to move to one side. The toothed plate 87 meshes with the gear 88 and drives it to rotate. The gear 88 drives the third lead screw 82 to rotate. The third lead screw 82 drives the third moving block 83 to move down. The third moving block 83 drives the pressure plate 84 on it to move down. The pressure plate 84 drives the positioning tube 85 to be inserted into the positioning hole 815 on the top of the first circuit breaker 814. The conductive contact 811 is then inserted into the conductive insertion groove 816 for electrical connection and conduction. The conductive contacts on the two pressure plates 84 811 is connected to the electrical input terminal of the charging plug 11 and the electrical output terminal of the second circuit breaker 15 respectively. The charging plug 11 in each charging chamber 2 is electrically connected in series with a first circuit breaker 814 to form a charging unit, and multiple charging units are electrically connected in parallel. The second circuit breaker 15 is electrically connected to multiple first circuit breakers 814 through the cooperation of conductive contact 811 and conductive plug slot 816, so that the electrical connection of the equipment is relatively complete. If a first circuit breaker 814 or charging unit fails, other charging units can still continue to work, improving the reliability and stability of the entire charging system. In addition, the output interface of the charging cabinet and the input interface of the first circuit breaker 814 are standardized, realizing the installation and electrical connection of the first circuit breaker 814. The connection process is simple and quick, without complicated wiring operations, which allows for quick disassembly and installation during maintenance or equipment replacement, greatly shortening downtime.

[0079] Working principle: When installing the first circuit breaker 814, the operation process is simple and efficient. First, the positioning hole 815 at the bottom of the first circuit breaker 814 is precisely aligned with the positioning tube 85 at the bottom of the second mounting plate 81 and inserted. During this process, the conductive contact 811, which is slidably inserted inside the positioning tube 85, will smoothly enter the conductive insertion groove 816 on the inner wall of the positioning hole 815, thereby achieving stable electrical contact and conductivity between the conductive insertion groove 816 and the conductive contact 811, which lays the foundation for subsequent power transmission.

[0080] Subsequently, by pushing the second push rod 810, the movable plate 86 is moved to one side. A toothed plate 87 is provided in the third mounting groove on the outer wall of the movable plate 86, and moves together with the movable plate 86. The toothed plate 87 meshes with the gear 88 located in the third mounting groove. When the toothed plate 87 moves, it drives the gear 88 to rotate. The gear 88 is connected to the third lead screw 82, which in turn drives the third lead screw 82 to rotate. Since the outer wall of the third lead screw 82 is threaded with a third moving block 83, as the third lead screw 82 rotates... When the third moving block 83 moves downward along the direction of the lead screw, it will drive itself and the pressure plate 84 on the outer wall of the second mounting plate 81 to move downward. The pressure plate 84 further drives the positioning tube 85 to be inserted into the positioning hole 815 at the top of the first circuit breaker 814, so that the conductive contact 811 in the positioning tube 85 is inserted into the conductive plug slot 816 again, completing another set of stable electrical connection and conduction, thereby ensuring the stable electrical connection of the first circuit breaker 814 in the entire charging system.

[0081] In the entire charging system, each charging plug 11 in the charging chamber 2 is electrically connected in series with a first circuit breaker 814 to form a charging unit. Multiple such charging units are electrically connected in parallel. At the same time, the second circuit breaker 15 is located inside the first mounting slot 3. It achieves electrical connection with multiple first circuit breakers 814 through the tight cooperation of conductive contacts 811 and conductive plug slots 816. This design makes the electrical connection layout of the equipment extremely perfect. When a first circuit breaker 814 or a charging unit fails, other charging units can still continue to work normally, effectively ensuring the reliability and stability of the entire charging system.

[0084] S2. Real-time monitoring and anomaly detection: The sensor 10 monitors the flame, smoke or temperature data in the charging chamber 2 in real time; if an anomaly is detected, the release mechanism 4 and the receiving mechanism 5 are triggered to work together.

[0085] S3. Fired battery detachment: Motor 17 drives the first lead screw 413 to rotate, which drives the electric push rod 416 to move to the corresponding top plate 411 position; the electric push rod 416 pushes the top plate 411 to retract the inclined plate block 45, release the limit of the opposite square plug rod 42, and the push plate 43 pushes the battery out of the charging chamber 2.

[0086] S4. Receiving and buffering: Synchronously drive the second lead screw 51 to move the processing box 55 to below the charging chamber 2; the battery slides into the processing box 55 via the adjusting plate 58, and the elliptical buffer ring 76 and the fourth spring 74 buffer and fix the battery in stages;

[0087] S5. Fire extinguishing: Start the fire pump 13, and the extinguishing agent is sprayed onto the surface of the battery through the fire nozzle 14;
