Description

Technical Field

[0001] This invention relates to the field of protection technology for the transportation of new energy battery cells, specifically to a foam-fixed insulating protective structure for transporting welded aluminum battery cells. Background Technology

[0002] After the aluminum tabs of the battery cells are welded, they need to be transferred to the next process or storage area. Lithium batteries are chemically active, and mechanical bumps during transportation, environmental temperature rise, and defects in the cells themselves can easily cause thermal runaway, resulting in fires and explosions. Therefore, the battery cell transfer device must have reliable buffer insulation, temperature monitoring, and emergency protection capabilities.

[0003] Existing battery cell transport boxes mostly use a fixed, integrated foam liner for buffering and limiting the movement of the cells. A few devices are equipped with temperature sensors, which can only provide basic over-temperature alarms. The overall protection solution still has significant shortcomings: First, the fixed foam structure cannot be adapted to multiple specifications of battery cells, and the buffering and insulation protection effect is limited. Impacts during transportation can easily damage the welded aluminum plates of the battery cells, and friction of the shell can easily generate static electricity and short circuit hazards. Second, there is a lack of a graded temperature control system. It can only alarm but cannot actively cool down, and minor overheating problems cannot be resolved in advance. Third, there is no structure for automatically separating faulty battery cells. Abnormal battery cells are stored in the same cavity as normal battery cells, which can easily lead to a chain of thermal runaway. Moreover, there is no automatic fire extinguishing structure, and manual handling is extremely risky. Fourth, the early warning method is single, and there is no independent personal alarm terminal, so transport personnel cannot be informed of internal faults in a timely manner.

[0004] In summary, existing battery cell transport structures suffer from poor adaptability, insufficient temperature control emergency response capabilities, and low automation in fault handling, failing to meet the requirements for safe transport of large quantities of welded aluminum plate battery cells. To address these technical deficiencies, this invention proposes a foam-fixed insulating protective structure for transporting welded aluminum plate battery cells. Summary of the Invention

[0005] The main objective of this invention is to provide a foam-fixed insulation and protection structure for transporting welded aluminum battery cells.

The bottom of the outer storage box is provided with a second motor. The output shaft of the second motor is connected to a second winding wheel. A second pull cable is wound on the second winding wheel. The end of the second pull cable away from the second winding wheel passes through the bottom of the outer storage box, extends into the second sliding groove, and is connected to the bottom of the second locking block.

Below the battery cell receiving slot, there is a burial groove that includes the through hole. The upper opening of the burial groove and the bottom of the battery cell receiving slot are detachably connected by multiple electronic magnetic locks. The bottom of the battery cell receiving slot is equipped with a lifting mechanism for raising and lowering the battery cell receiving slot; The outer wall of the cell receiving slot, on the side closest to the material discharge hole along the length direction, is provided with a burial assembly for discharging fire extinguishing sand into the burial slot.

[0016] In the technical solution of this invention, a modular array splicing loading unit structure is adopted, which can realize the independent storage of a large number of battery cells in different areas. Individual battery cells do not interfere with each other, and an abnormality in a single battery cell will not directly affect the surrounding normal battery cells, resulting in excellent zone control. Combined with a replaceable magnetic foam buffer structure, it is compatible with multiple specifications of welded aluminum plate battery cells, reducing equipment replacement costs.

[0017] It achieves two-level intelligent control of battery cell temperature: the first level activates directional air cooling for precise temperature reduction when overheating, and the second level automatically unlocks and ejects the battery cell when it is close to the spontaneous combustion critical point. The graded treatment is in line with the thermal runaway temperature rise law of the battery cell, and curbs the risk of battery cell fire from the source.

[0018] The entire process of abnormal cell positioning, support plate displacement, cell unloading, sand burial, and flue gas exhaust is completed automatically, eliminating the need for manual opening of the enclosure for close-range operation and avoiding the safety risks of manual emergency response.

[0019] The sunken burial trench with sealed sand burial design, combined with the exhaust fan at the bottom of the box to quickly expel combustion smoke, provides double protection against the spread of fire and completely avoids chain thermal runaway of normal battery cells; at the same time, it is equipped with a personal sound and light alarm, so that transport personnel can be notified of equipment abnormalities in real time from a distance.

[0030] This invention proposes a foam-fixed insulating protective structure for transporting welded aluminum battery cells.

[0031] Please refer to Figures 1 to 12 The foam-fixed insulation and protective structure for transporting welded aluminum battery cells includes a transfer box 1 and a central controller electrically connected to each component. The transfer box 1 has a door 2 on at least one side wall. A partition 3 is horizontally fixed inside the transfer box 1, and battery cell loading groups are provided on the partition 3 in a number corresponding to the number of doors 2. The battery cell loading assembly includes a battery cell loading component and an abnormal battery cell unloading and receiving component 5. The battery cell loading assembly includes a support plate 6 that is slidably mounted on the partition plate 3. The support plate 6 is provided with a battery cell loading unit. The battery cell loading unit consists of several loading units 4 arranged in a horizontal and vertical array and spliced ​​together. The horizontal arrangement direction of the loading units 4 is parallel to the door 2. The loading unit 4 includes an outer storage box and a cell storage box 43. The outer storage box 42 has a retrieval opening on one side facing the door 2. The cell storage box 43 is housed inside the outer storage box 42 through the retrieval opening. The outer storage box 42 is equipped with a cell status monitoring module and a pop-out component linked to it. The cell status monitoring module is used to detect the cell status. When the cell status monitoring module detects a cell abnormality, the pop-out component pushes out the cell storage box 43 containing the abnormal cell. The abnormal cell unloading receiving component 5 is used to receive the cell storage box 43 ejected from the pop-up component and to isolate the cell storage box 43 from the cell loading component.

[0032] In the technical solution of this invention, a modular array splicing loading unit 4 structure is adopted, which can realize the independent storage of a large number of battery cells in different areas. The individual battery cells do not interfere with each other, and the abnormality of a single battery cell will not directly affect the surrounding normal battery cells, resulting in excellent zone control. Combined with a replaceable magnetic foam buffer structure, it is compatible with multiple specifications of welded aluminum plate battery cells, reducing equipment replacement costs.

[0033] It achieves two-level intelligent control of battery cell temperature: the first level activates directional air cooling for precise temperature reduction when overheating, and the second level automatically unlocks and ejects the battery cell when it is close to the spontaneous combustion critical point. The graded treatment is in line with the thermal runaway temperature rise law of the battery cell, and curbs the risk of battery cell fire from the source.

[0034] The entire process of abnormal cell positioning, support plate displacement, cell unloading, sand burial, and flue gas exhaust is completed automatically, eliminating the need for manual opening of the enclosure for close-range operation and avoiding the safety risks of manual emergency response.

[0035] The sunken burial trench 53 features a sealed sand-buried design, which, together with the exhaust fan 44 at the bottom of the enclosure, quickly exhausts combustion smoke, effectively blocking the spread of fire and completely preventing the normal cells from experiencing a chain reaction of thermal runaway. It is also equipped with a personal audible and visual alarm, allowing transport personnel to receive real-time information about equipment malfunctions from a distance.

[0036] With strong structural linkage, all electrical control components are uniformly controlled by a central controller, and the coordinate positioning is accurate. It can accurately match the position of each loading unit 4, and the abnormal battery cell is unloaded with zero deviation. The box body has a built-in rainproof and breathable structure, which takes into account both ventilation and heat dissipation and protection during rainy weather transportation.

[0037] Please refer to the appendix. Figure 6 , 9 -10, the outer storage box 42 is provided with a blocking component, which is used to prevent the battery cell storage box 43 from coming out of the outer storage box 42; The bottom of the inner wall of the outer storage box 42 is recessed to form a first groove 42a. The blocking component includes a first locking block 437 slidably disposed in the first groove 42a. The first locking block 437 is connected to the bottom of the first groove 42a by a first spring 438. The first spring 438 is used to drive the end of the first locking block 437 away from the first groove 42a to extend out of the first groove 42a. The bottom of the outer storage box 42 is provided with a first motor 439. The output shaft of the first motor 439 is connected to a first winding wheel 4310. A first cable 4311 is wound on the first winding wheel 4310. The end of the first cable 4311 away from the first winding wheel 4310 passes through the bottom of the outer storage box 42, extends into the first groove 42a, and is connected to the bottom of the first locking block 437. The end face of the first card block 437 extending out of the first slide groove 42a is an inclined surface that faces the inside of the outer storage box 42; A control button is installed on the outer wall of the outer storage box 42 on the same side as the retrieval opening. Pressing the control button causes the first motor 439 to rotate forward and retract the first cable 4311. When the central controller detects the press signal of the control button, it starts timing. After the timing reaches a preset threshold, it controls the first motor 439 to rotate in reverse and release the first cable 4311.

[0038] The addition of a blocking component to lock the battery cell storage box 43 in a normal state can completely prevent the battery cell storage box 43 from accidentally slipping out during transportation, prevent the battery cells from falling off or being damaged by bumps, and improve the storage stability under normal transportation conditions.

[0039] It adopts a purely mechanical linkage unlocking structure of spring + coil wheel + cable, which is simple and durable, with a failure rate far higher than that of a purely electric push rod structure. It is also suitable for bumpy and vibration environments during transportation and has a longer service life.

[0040] The first card block 437 has a sloping structure design. When the battery cell storage box 43 is pushed in for installation, the card block can be automatically squeezed and retracted, eliminating the need for manual unlocking. This makes the battery cell loading and installation operation convenient and labor-saving.

[0041] The control buttons are paired with the central controller's delay control logic. When manually removing and placing the battery cells, the motor delays and resets the card block, allowing sufficient time for manual removal and placement. This prevents the card block from prematurely rebounding and jamming the battery cell storage box 43, thus improving the fault tolerance rate of manual operation.

[0042] Please refer to the appendix. Figure 6 The inner bottom wall of the outer storage box 42 is provided with two parallel slides 42c. Each slide 42c is equipped with a slide rod 4313 extending along the direction of the take-out opening. A slider is slidably installed on each slide rod 4313, and the upper part of the slider extends out of the slide 42c. The protruding ends of the two sliders are connected to the push plate 4312. Each of the slide bars 4313 is fitted with a second spring 4314, which is located on the side of the slide bar facing away from the pick-up and put-out opening. The bottom wall inside the outer storage box 42 is also provided with a positioning component for limiting and fixing the push plate 4312.

[0043] The energy storage and ejection mechanism is composed of slide bar 4313, slider, push plate 4312 and second spring 4314. Under normal conditions, it relies on the elastic potential energy of the spring to store energy. When the battery cell is ejected abnormally, there is no need for an additional high-power drive motor, which reduces the overall energy consumption and manufacturing cost of the equipment.

[0044] The slide rail 42c and slide rod 4313 limit and guide structure ensure that the push plate 4312 can only move in a straight line along the direction of picking up and putting in the battery cell, avoid the push plate 4312 from deviating and getting stuck, ensure that the battery cell popping process is smooth and stable, and prevent secondary impact damage to the battery cell during the popping process.

[0045] The feeding process automatically compresses the spring for energy storage, eliminating the need for separate manual energy storage. The loading of the battery cells and the energy storage of the springs are completed simultaneously, simplifying the battery cell loading process and improving the efficiency of battery cell loading.

[0046] The positioning component can stably lock the push plate 4312 to the position, and fix the battery cell storage box 43 to the position throughout the transportation process, eliminating the problem of springs accidentally popping out and ensuring the safety of normal battery cell transportation.

[0047] Please refer to the appendix. Figure 7 The battery cell storage box 43 includes a box body 431 and a box cover 432 hinged to the top of the box body 431; at least one buffer strip 433 is magnetically attached to the inner wall of each side of the box body 431, and a buffer block 435 is magnetically attached to the side of the box cover 432 facing the box body 431; a buffer layer is laid on the bottom wall of the box body 431. The box body 431 is inserted into the opening along its own length direction, and several heat dissipation holes 436 are respectively opened on the two side walls along the length direction of the box body 431. Rollers are respectively provided on the outer wall of the box body 431 and the top surface of the box cover 432.

[0048] The box body 431 and the lid 432 form a sealed storage structure that fully encloses the battery cell. Combined with the full foam material cushioning strips 433, cushioning blocks 435, and cushioning layers, it achieves all-round foam cushioning and insulation protection on the top, bottom, four sides, and six sides of the battery cell. It is suitable for all working conditions such as start-stop, bumps, and turns during transportation and effectively protects the aluminum plate welding position from impact and cracking.

[0049] The entire buffer structure adopts a magnetic detachable installation method, which allows for quick replacement of different specifications of foam buffers according to the length, width and height of the battery cell, without the need to replace the entire storage box, greatly reducing the cost of equipment use and improving the compatibility of the storage box with different models of welded aluminum plate battery cells.

[0050] The box 431 has distributed heat dissipation holes 436 on both sides to form a convection heat dissipation channel. Together with the subsequent fan 44, it can realize directional ventilation and heat dissipation inside the battery cell, solving the problem of poor heat dissipation in the sealed storage box.

[0051] The addition of rollers to the outer wall and top surface reduces frictional resistance during the pushing and popping of the battery cell storage box 43, making the sliding smoother, further reducing the load on the pop-up mechanism and extending the service life of the drive components.

[0052] Please refer to the appendix. Figure 4-5 The cell status monitoring module includes a temperature sensor, which is installed on the top surface of the inner wall of the outer storage box 42; a through monitoring hole 434 is provided on the box cover 432 corresponding to the position of the temperature sensor, and the temperature sensor can monitor the temperature of the cells inside the cell storage box 43 in real time through the monitoring hole 434.

[0053] The temperature sensor is mounted on the top and is paired with the monitoring hole 434 on the cover. The sensor is directly above the battery cell, allowing for unobstructed monitoring of the battery cell temperature. The temperature detection data is accurate and without deviation, avoiding detection errors caused by temperature differences in the sealed box 431.

[0054] The independent temperature monitoring mode for each individual cell can accurately locate the specific location of each abnormal cell, unlike the drawback of overall temperature measurement of the enclosure which cannot locate the faulty cell. Subsequent material handling and isolation can be accurately aligned, eliminating problems of incorrect or missing material handling.

[0055] The non-contact temperature measurement method avoids direct contact between the temperature sensor and the battery cell surface, preventing damage caused by the temperature measuring component pressing against the battery cell casing. It also achieves electrical isolation and improves the insulation safety performance of the temperature measuring module itself.

[0056] Please refer to the appendix. Figure 5 , 6 9 and 11, the bottom of the inner wall of the outer storage box 42 is recessed to form a second sliding groove 42b. The positioning component includes a second locking block 4315 slidably disposed in the second sliding groove 42b. The second locking block 4315 is connected to the bottom of the second sliding groove 42b by a third spring 4316. The third spring 4316 is used to drive the end of the second locking block 4315 away from the second sliding groove 42b to extend out of the second sliding groove 42b. The push plate 4312 is recessed on the side near the bottom wall of the outer storage box 42 to form a slot 4312a for the second locking block 4315 to be inserted. The bottom of the outer storage box 42 is provided with a second motor 4318. The output shaft of the second motor 4318 is connected to a second winding wheel. A second pull cable 4317 is wound on the second winding wheel. The end of the second pull cable 4317 away from the second winding wheel passes through the bottom of the outer storage box 42, extends into the second sliding groove 42b, and is connected to the bottom of the second locking block 4315. The end face of the second card block 4315 extending out of the second slide groove 42b is an inclined surface facing inward; the second motor 4318 is electrically connected to the temperature sensor and the central controller respectively; A fan 44 electrically connected to the central controller is installed through the side wall of the outer storage box 42 facing away from the retrieval opening. The fan 44 is used to blow air toward the retrieval opening. The door 2 has multiple rainproof vents arranged in an array.

[0057] When the temperature sensor detects that the temperature of the battery cells inside the battery cell storage box 43 exceeds the first preset value, the central controller controls the fan 44 to start and circulate air through the battery cell storage box 43. The air enters the battery cell storage box 43 from the heat dissipation hole 436 on the side of the box body 431 near the inner side of the outer storage box 42, and exits from the heat dissipation hole 436 on the side of the box body 431 near the access opening. In the process, the air carries away the heat from the battery cells, thereby cooling the battery cells inside the battery cell storage box 43. After the battery cell temperature exceeds the second preset value, the central controller controls the second motor 4318 to reverse so as to drive the second winding wheel to rotate and thus wind up the second cable 4317, further driving the second locking block 4315 to move towards the side of the second slide groove 42b. Until the second locking block 4315 is dislodged from the slot 4312a, after the second locking block 4315 is dislodged from the slot 4312a, the push plate 4312 loses the limit of the second locking block 4315. At this time, the second spring 4314 releases elastic potential energy to drive the push plate 4312 to move towards the side closer to the pick-up and drop-off opening. The push plate 4312 moves to push the battery cell storage box 43 out of the outer storage box 42, further enabling the abnormal battery cell unloading receiving component 5 to accept the battery cell storage box 43 loaded with abnormal battery cells. (If the battery cell temperature reaches the second preset value, it means that the temperature of the battery cell cannot be reduced by air cooling and is continuing to rise. The value of the second preset value is ninety percent of the battery cell's self-ignition temperature critical point.) Two temperature thresholds are set to achieve differentiated emergency handling: the first threshold activates air-cooled directional cooling, prioritizing physical cooling to eliminate minor overheating faults, reducing unnecessary cell scrapping, and saving production costs.

[0058] The secondary threshold is set at 90% of the cell's spontaneous combustion temperature critical point. This allows for early prediction of the risk of thermal runaway in the cell and automatic isolation before the cell catches fire or explodes, seizing the emergency response window and preventing spontaneous combustion accidents from the source.

[0059] The second locking block 4315, the third spring 4316, and the cable linkage positioning component precisely lock the push plate 4312, completely locking the ejection mechanism during normal transportation. It only unlocks automatically when the battery cell reaches a dangerous temperature, making the probability of equipment malfunction extremely low.

[0060] The door 2 has a rainproof vent, which is paired with an internal fan 44 to ensure internal heat dissipation and convection while preventing rainwater from entering the box during rainy weather. It combines the dual functions of ventilation and heat dissipation with rain protection.

[0061] The 44-fan directional airflow, combined with the dual-sided heat dissipation holes 436, forms a straight convection airflow channel, which provides targeted air cooling, cooling only the overheated battery cells individually, eliminating the need for ventilation of the entire box and reducing heat dissipation energy consumption.

[0062] Please refer to the appendix. Figure 3 The abnormal cell unloading receiving assembly 5 includes a cell receiving slot 51, which is a rectangular structure and is arranged horizontally below the partition 3. The length direction of the cell receiving slot 51 is consistent with the horizontal arrangement direction of the loading unit 4, and the slot opening length of the cell receiving slot 51 is greater than the total length of the horizontal distribution of all loading units 4. The bottom wall of the battery cell receiving slot 51 near the side wall in the length direction is formed by a through hole through which the battery cell storage box 43 passes at any angle. Below the battery cell receiving slot 51, there is a burial slot 53 that includes the through hole. The upper opening of the burial slot 53 is detachably connected to the bottom of the battery cell receiving slot 51 by a multi-electromagnetic lock. The bottom of the battery cell receiving slot 51 is provided with a lifting mechanism 52 for driving the battery cell receiving slot 51 to rise and fall; The outer wall of the cell receiving groove 51, on the side closest to the material discharge hole along the length direction, is provided with a burial assembly for discharging fire extinguishing sand into the burial groove 53. The partition plate 3 has a power supply core receiving slot 51 and a lifting hole 3a through which the buried component passes; when the support plate 6 moves to be directly above the lifting hole 3a, it can completely cover the lifting hole 3a. The lifting hole 3a is located on the side of the loading and unloading opening facing the box door 2; a guide block 55 is provided in the battery cell receiving slot, and the side of the guide block 55 facing away from the bottom of the battery cell receiving slot forms an inclined surface, and the inclined surface is coated with grease. The abnormal cell unloading receiving component 5 also includes a moving component for moving the support plate 6 toward a side closer to or away from the lifting hole 3a, so that the support plate 6 moves above the lifting hole 3a. Multiple exhaust fans 44 are provided through the side wall of the transfer box 1. The exhaust fans 44 are located below the partition 3 and are used to exhaust the gas inside the transfer box 1.

[0063] The central controller records the coordinate position of each loading unit 4. When the central controller detects that the temperature of a cell in a loading unit 4 exceeds the second threshold, it controls the moving component to move the support plate 6 away from the lower door 2, so that the lifting hole 3a is exposed. Then, it controls the lifting mechanism 52 to move the cell receiving slot 51 to the side below the loading unit 4 with the abnormal cell according to the coordinates of the loading unit 4 with the abnormal cell. The second motor 4318 inside the loading unit 4 rotates, causing the second locking block 4315 to disengage from the slot, so that the second spring 4314 drives the push plate 4312 to push out the cell storage box 43. The pushed-out cell storage box 43... Entering the cell receiving slot 51, the cell storage box 43 slides towards the discharge through hole under the guidance of the guide block 55 and falls into the burial slot 53. Then, the central controller controls the elevator 52 to drive the cell receiving slot 51 down to below the partition 3. Then, the control moving component drives the support plate 6 to move above the lifting hole 3a and cover the lifting hole 3a to isolate the cell storage box 43 containing abnormal cells from the normal cells. At the same time, the burial component injects fireproof sand into the burial slot 53 to completely bury the cell storage box 43. The exhaust fan 44 works to exhaust the smoke generated by the burning of the cells. The central controller records the 4-axis coordinates of all loaded cells, enabling precise positioning of abnormal cells. The elevator 52 can accurately align itself below the abnormal cell, ensuring that the cell can fall precisely into the receiving slot after being ejected, with no offset during unloading.

[0064] The support plate 6 can be moved to cover the lifting hole 3a. Under normal circumstances, the lifting hole 3a is closed to ensure the airtightness of the upper battery cell storage area; in an emergency, the lifting hole 3a is opened to complete the unloading. The structure has a high reusability and does not require a separate fixed unloading port.

[0065] With a guide block featuring a 55-degree bevel and grease lubrication, the battery cell storage box 43 automatically and smoothly slides into the unloading through hole, eliminating the need for additional drive components to push the battery cells and simplifying the overall transmission structure.

[0066] The sunken burial tank 53 independently isolates abnormal battery cells, completely separating them from the upper normal battery cell storage space. Together with the bottom exhaust fan 44, it promptly exhausts smoke and prevents smoke accumulation and temperature rise, which could lead to secondary safety hazards.

[0067] The lifting hole 3a is located on one side of the door 2, close to the manual operation side, making subsequent equipment inspection and component maintenance more convenient.

[0068] Please refer to the appendix. Figure 3 and 12The burial assembly includes a sand storage box 54, which is pre-stored with fire extinguishing sand. A first sand outlet hole is formed on the lower side of the sand storage box 54 near the battery cell receiving slot 51. The inner wall of the sand storage box 54 on the side away from the battery cell receiving slot 51 is an inclined surface that guides the fire extinguishing sand to the first sand outlet hole. A second sand outlet hole is formed through the side wall of the battery cell receiving slot 51 and communicates with the first sand outlet hole. A receiving hole is formed by the upper wall of the second sand outlet hole. A sealing plate 57 for sealing the second sand outlet hole is slidably provided in the receiving hole. The inner wall of the cell receiving slot 51 near the sand storage box 54 is provided with an electric telescopic rod 56. The inner side wall of the cell receiving slot 51 near the sand storage box 54 is formed with a rectangular sliding hole that communicates with the receiving hole. A transmission rod 58 is slidably arranged in the sliding hole. The sliding direction of the transmission rod 58 is the same as the sliding direction of the sealing plate 57. The output shaft of the electric telescopic rod 56 is connected to the transmission rod 58.

[0069] The sand storage box 54 is integrated into the side wall of the battery cell receiving slot 51, eliminating the need for external fire extinguishing sand supply equipment. The equipment has a high degree of integration, occupies little space, and is suitable for the narrow internal space of the transfer box 1.

[0070] The inclined sand guiding structure ensures that the extinguishing sand can be completely discharged by gravity without any sand accumulation, ensuring that a sufficient amount of sand can be discharged for each emergency firefighting, and that the fire extinguishing effect is stable and reliable.

[0071] The electric telescopic rod 56 is linked to the sealing plate 57. The electric control opens and closes the sand outlet with a fast response speed and precise and controllable opening and closing action. The amount of sand discharged can be precisely controlled according to the size of the fire to avoid wasting fire extinguishing sand.

[0072] The transmission rod 58 slides through the hole for horizontal transmission, and the sealing plate 57 blocks vertically, changing the transmission direction to fit the narrow installation space of the box, making the structural layout more compact and reasonable.

[0073] Please refer to the appendix. Figure 2 The moving component includes a hydraulic cylinder 41 fixed on the partition 3. The output shaft of the hydraulic cylinder 41 is connected to the support plate 6. The hydraulic cylinder 41 is used to drive the support plate 6 to move toward or away from the box door 2.

[0074] Hydraulic cylinder 41 is used as the power source for the moving component. Compared with pneumatic cylinders and electric push rods, hydraulic cylinder 41 has greater thrust and smoother operation, and can drive the heavy support plate 6, which is fully loaded with multiple battery cells, to move smoothly.

[0075] Please refer to the appendix. Figure 1 It also includes an alarm module, which includes an audible and visual alarm light that is wirelessly connected to the central control module.

[0076] The alarm module uses a wireless connection. The audible and visual alarm lights are carried by the transport personnel, eliminating the need for wired wiring and simplifying the wiring process. At the same time, personnel can receive abnormal signals from inside the container in real time from a distance without having to approach the dangerous transport container 1.

[0077] With a dual alarm mode of sound and light, the system provides both strong light and high-decibel sound alerts, ensuring clear warnings to drivers and escorts even in noisy transportation environments, leaving no blind spots in the warning.

[0078] The alarm signal is triggered after the abnormal battery cell has been isolated and buried. The timing of the warning is reasonable, so that it will not cause false alarms that interfere with normal transportation, nor will it cause alarms that are delayed and miss the emergency opportunity.

[0079] The specific operation method of this invention is as follows: The overall workflow of this structure is divided into five stages: cell loading and assembly, normal transport monitoring, primary overheating air cooling, secondary critical temperature emergency isolation and fire extinguishing, and finished cell unloading. The working process of each stage is as follows: Cell filling and assembly The staff opens the door 2 of the transfer box 1 and presses the control button on the outer wall of the outer storage box 42. After receiving the press signal, the central controller controls the first motor 439 to rotate forward and wind up the first cable 4311, pulling the first locking block 437 back into the first slide groove 42a, thus releasing the obstruction limit at the entrance of the battery cell storage box 43. Then, the battery cell storage box 43, pre-installed with welded aluminum plate battery cells, is pushed into the outer storage box 42 through the pick-and-place opening. During the movement of the battery cell storage box 43, the push plate 4312 is squeezed and slides axially along the slide rod 4313, simultaneously compressing the second spring 4314 to complete the storage of elastic potential energy. After the battery cell storage box 43 is fully in place, the second locking block 4315 pops out under the elastic force of the third spring 4316 and locks into the bottom slot 4312a of the push plate 4312, completing the locking and fixing of the push plate 4312 and preventing the second spring 4314 from accidentally rebounding. Simultaneously, the central controller's built-in timer completes the delay timing. After the timing ends, it controls the first motor 439 to reverse and release the first cable 4311. The first locking block 437 resets and extends, axially limiting the battery cell storage box 43 to prevent it from slipping due to transportation bumps. After all the battery cells of the loaded individual cells 4 are assembled in sequence, the box door 2 is closed, and the device enters the real-time monitoring standby state.

[0080] Routine transport monitoring conditions During the cell transfer process, each temperature sensor continuously collects real-time temperature data of the corresponding cell through the monitoring hole 434 of the cover 432 in a non-contact manner, and transmits the data back to the central controller in real time. Under this condition, all drive motors, hydraulic cylinders 41, lifting platforms 52, fans 44 and alarm modules are in a sleep standby state; the support plate 6 always covers the lifting hole 3a on the surface of the partition 3 to achieve physical isolation between the upper and lower cavities; the multi-layer foam buffer structure inside the cell storage box 43 continuously buffers the vibration and impact of transportation, while achieving all-round insulation protection for the cells; the rainproof vent on the side wall of the box remains stationary, taking into account the dustproof and waterproof performance of the box in rainy weather, ensuring stable transfer of the cells.

[0081] Level 1 superheated air-cooled cooling condition When the temperature sensor detects that the cell temperature has reached the first preset temperature threshold, it determines that the cell has experienced a slight overheating anomaly, but has not yet reached the risk value for thermal runaway. The central controller immediately activates the cooling fan 44 on the rear side of the corresponding outer storage box 42. The fan 44 directs airflow towards the access opening, and the airflow sequentially passes through the heat dissipation holes 436 on both sides of the cell storage box 43 to form a convection airflow channel, quickly removing the heat accumulated on the surface of the cell, achieving precise air cooling for a single cell. The central controller continuously monitors changes in cell temperature. Once the cell temperature drops back to the safe standard range, it automatically shuts down the cooling fan 44, and the device automatically resets to the normal monitoring mode without manual intervention.

[0082] Level II critical temperature emergency isolation and fire extinguishing conditions If the battery cell continues to heat up and reaches the second preset temperature threshold, which is 90% of the battery cell's spontaneous combustion critical point, it is determined that the battery cell is about to experience thermal runaway, and the central controller activates a full set of emergency protection procedures. First, it retrieves the pre-stored coordinate data of the loading unit 4 and controls the hydraulic cylinder 41 of the moving component to drive the support plate 6 to move laterally, exposing the lifting hole 3a on the partition plate 3; then, it controls the lifting machine 52 to move the battery cell receiving slot 51 precisely to directly below the abnormal loading unit 4. Immediately afterwards, the central controller controls the second motor 4318 to wind the second cable 4317, causing the second locking block 4315 to retract and disengage from the slot 4312a, the push plate 4312 to release its limit, and the second spring 4314 to release its stored elastic potential energy, pushing the battery cell storage box 43 to smoothly pop out of the outer storage box 42. After popping out, the battery cell storage box 43 falls into the battery cell receiving slot 51, slides smoothly along the inclined surface of the guide block 55, and falls into the lower burial slot 53 through the material discharge hole. After the material is unloaded, the elevator 52 drives the battery cell receiving slot 51 to return to its original position, and the hydraulic cylinder 41 drives the support plate 6 to seal the lifting hole 3a again, preventing the fire from spreading upwards. Subsequently, the electric telescopic rod 56 is activated, opening the sand discharge channel, and the fire extinguishing sand inside the sand storage box 54 flows by gravity to fill the burial trench 53, completely burying the faulty battery cell to suffocate it. At the same time, the exhaust fan 44 at the bottom of the transfer box 1 starts synchronously to promptly exhaust the smoke inside the box and prevent the smoke from accumulating and heating up. After all emergency actions are completed, the central controller sends an alarm signal to the wireless audible and visual alarm module, and the audible and visual alarm carried by the transport personnel simultaneously issues an audible and visual warning to remind maintenance personnel to troubleshoot the fault in a timely manner.

[0083] Cell unloading operation After the battery cells are transferred to their destination, the staff opens the box door 2 and presses the control button at the corresponding position again to briefly release the obstruction limit of the first locking block 437, allowing the battery cell storage box 43 to be pulled out directly, completing the battery cell unloading operation. After unloading is completed, releasing the control button will automatically reset and lock the blocking component, allowing the device to directly start the next round of battery cell transfer operations, demonstrating strong reusability.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
