Description

Technical Field

[0001] This invention belongs to the field of lithium batteries, specifically, it relates to a safe storage and transportation device for retired power lithium batteries. Background Technology

[0002] Retired lithium-ion batteries may experience short circuits, leaks, and overheating during transportation. These problems can lead to fires, explosions, and other safety accidents, posing significant potential transportation risks. Furthermore, fires involving retired lithium-ion batteries are generally more difficult to extinguish than those involving other goods, easily causing severe personal injury and property damage. Currently, the transportation of retired lithium-ion batteries remains unresolved. While specialized logistics companies and vehicles should handle the transport of used batteries, there is currently no mature and effective system for the safe transportation of retired batteries.

[0003] Traditional battery transport devices cannot effectively monitor the state of the batteries within the transport space or the battery status during transport. If a battery catches fire during transport, a major safety accident is likely to occur. For example, a lithium battery transport device (patent number CN201911327134.3) includes: a frame with a battery receiving slot for accommodating the battery body; and a sealing device positioned above the frame and movable relative to it, capable of sealing the electrolyte filling port on the battery body. This lithium battery transport device cannot effectively control high temperatures or fires that may occur during transport, and therefore cannot guarantee the safety of transporting large quantities of lithium batteries.

[0036] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0037] The following is in conjunction with the appendix Figure 1-13 The present invention will be described in further detail below.

[0038] To facilitate understanding of the above technical solutions of the present invention, the following detailed embodiments will further illustrate the above technical solutions of the present invention. Example

[0039] like Figure 1 As shown, a safe storage and transportation device for retired power lithium batteries includes: a transport box 1, which has a first placement area 3 for placing a battery storage mechanism 2 and a second placement area 5 for placing a cooling and fire extinguishing mechanism 4; the cooling and fire extinguishing mechanism 4 is connected to the battery storage mechanism 2 and is used to cool or extinguish the batteries stored in the battery storage mechanism 2.

[0040] This invention provides a safe storage and transportation device for retired power lithium batteries, enabling safe transportation and storage of these batteries. It effectively prevents potential fires, explosions, and other safety accidents during transportation, ensuring the safety of the battery transport process. A cooling and fire extinguishing mechanism 4 is installed in the second placement area 5 of the transport box 1. This mechanism 4 is connected to the battery storage unit 2. In the event of excessively high lithium battery temperature or fire, the cooling and fire extinguishing mechanism 4 can cool or extinguish the fire in the battery storage unit 2, effectively handling unexpected situations during lithium battery transportation and reducing the risk range of retired power lithium batteries during storage and transportation. The cooling and fire extinguishing mechanism 4 uses liquid nitrogen for fire extinguishing, effectively controlling battery fires and ensuring the safety of the retired power battery storage and transportation process.

[0041] The battery storage mechanism 2 includes one or more storage boxes 6 detachably connected to the first placement area 3, effectively controlling the range of battery fire and explosion. Each storage box 6 is independent and does not affect the others. A temperature sensor 7 for detecting battery temperature and a spray mechanism 8 for spraying water onto the battery are installed inside the storage box 6. The spray mechanism 8 is connected to the cooling and fire extinguishing mechanism 4 via a pipe with an electrically controlled valve 16. The temperature sensor 7 includes an infrared thermal imager, which is connected to the top surface inside the storage box 6. During transportation, the spraying mechanism 8 is connected to the cooling and fire extinguishing mechanism 4 via a pipe equipped with an electrically controlled valve 16, ensuring that liquid nitrogen in the cooling and fire extinguishing mechanism 4 can enter the spraying mechanism 8 and be sprayed into the storage tank 6. The temperature sensor 7 in this invention is always on. The temperature sensor 7 includes an infrared thermal imager, which monitors the internal temperature of the storage tank 6 and the battery temperature in real time. When an abnormal temperature is detected, the infrared thermal imager locates the abnormal point and sends feedback to the controller. The controller then controls the electrically controlled valve 16 to open, allowing the liquid nitrogen in the cooling and fire extinguishing mechanism 4 to be sprayed through the spraying mechanism 8, thus cooling or extinguishing the battery. To further improve safety, during monitoring, when the temperature sensor 7 detects a temperature rise to 50°C, liquid nitrogen spraying begins, and the spraying time is 10 minutes.

[0042] The cooling and fire extinguishing mechanism 4 includes a nitrogen storage tank, which is connected to the spray mechanism 8 via a pipeline. The nitrogen storage tank stores liquid nitrogen, thereby effectively cooling or extinguishing the battery. Multiple nitrogen storage tanks can be provided, and all tanks are connected to the spray mechanism 8 via pipelines through interfaces. The nitrogen pipeline in the second placement area 5 is designed as a rigid pipe connection, while the nitrogen pipeline connected to the spray mechanism 8 is designed as a flexible pipe for easy connection.

[0043] The opening of the storage box 6 is sealed to the movable door panel 10 by two or more buckles 9, which makes it easy to open or close, and provides good sealing and stability.

[0044] The bottom of the storage box 6 is connected to a fixing foot 11, which can be connected to the first placement area 3 by bolts and has a certain space to facilitate the handling by forklifts or various handling tools. When two adjacent storage boxes 6 are connected, the fixing foot 11 of one storage box 6 is connected to the upper surface of the other storage box 6 by bolts to ensure the stability of multiple storage boxes 6 during transportation.

[0045] The transport box 1 is also provided with a third placement area 13 for placing the electrical system control cabinet 12, and a fourth placement area 14 for storing items; the first placement area 3, the second placement area 5, the third placement area 13 and the fourth placement area 14 are all connected to box doors 15. Example

[0046] To further improve the safety of transporting retired power lithium batteries, a battery bracket 17 is also installed inside the storage box 6. This bracket can limit and fix the lithium batteries and provide shock absorption when shaking occurs during transport. The battery bracket 17 includes a shock-absorbing base 18 and a loading stand 19 mounted on the shock-absorbing base 18. A loading clamp 20 for clamping the battery is rotatably connected to the loading stand 19. The loading clamp 20 is used to clamp and fix the lithium batteries, and the loading stand 19 is used to support the loading clamp 20. The shock-absorbing base 18 is used to connect to the storage box 6 and provides a buffering and shock-absorbing function to prevent the batteries from hitting the inner wall of the storage box 6 or from being subjected to large-amplitude vibrations that could cause high temperatures or fires.

[0047] The shock-absorbing base 18 includes a mounting body 21, which has bolt holes for connecting to the lower surface of the storage box 6. A vertical shaft 22 is slidably connected inside a vertical tube 23 at the center of the mounting body 21. A shock-absorbing spring is fixed between the bottom of the vertical shaft 22 and the bottom surface of the vertical tube 23. A receiving body 24 for connecting the loading stand 19 is fixed to the top of the vertical shaft 22. Two hinge shafts 25 are rotatably connected to the bottom of the receiving body 24. The middle of the two hinge shafts 25 is fixedly connected to two shock-absorbing brackets 26. The other end of the two shock-absorbing brackets 26 is rotatably connected to two shock-absorbing slide rods 27. The two shock-absorbing slide rods 27 are slidably connected relative to each other in the shock-absorbing slide rails of the mounting body 21. The two shock-absorbing slide rods 27 are connected by multiple shock-absorbing tension springs 28.

[0048] During transportation, when vibrations occur due to road bumps, the loading clamp 20 equipped with lithium batteries can drive the support body 24 to move up and down via the loading stand 19. The support body 24 drives the vertical shaft 22 to slide within the vertical tube 23, and stretches or compresses the shock-absorbing spring. The shock-absorbing spring plays a role in buffering and absorbing shocks. The limiting post on the side of the vertical shaft 22 slides within the limiting hole on the side of the vertical tube 23 to prevent the vertical shaft 22 and the vertical tube 23 from separating. The up and down movement of the support body 24 can also drive the two hinge shafts 25 to move up and down. The two hinge shafts 25 drive one end of the two shock-absorbing brackets 26 to move up and down. The other end of the two shock-absorbing brackets 26 drives the two shock-absorbing slide rods 27 to slide relative to each other within the shock-absorbing slide rail of the mounting body 21. The two shock-absorbing slide rods 27 are connected by multiple shock-absorbing tension springs 28, thereby further buffering and absorbing shocks through the multiple shock-absorbing tension springs 28.

[0049] The loading clamp 20 includes a disc base 29 rotatably connected to the loading stand 19. A clamping controller 30 on the disc base 29 is connected to multiple clamping arm units 31. The multiple clamping arm units 31 are evenly connected around the disc base 29, and a clamping area for clamping batteries is formed between the multiple clamping arm units 31. The clamping controller 30 can control the multiple clamping arm units 31 to move closer or further away from each other, thereby changing the size of the clamping area formed between the multiple clamping arm units 31 for clamping batteries of different sizes. This invention is particularly suitable for the transportation of cylindrical batteries.

[0050] The clamping controller 30 includes a control worm gear 32 rotatably connected to the disc base 29, a control worm wheel 33 meshing with the control worm gear 32 and fixed to one end of a control shaft 34, a control bevel gear 35 fixed to the other end of the control shaft 34 and vertically meshing with multiple linkage bevel gears 36, the multiple linkage bevel gears 36 being fixed to the inner ends of multiple control screws 37, the multiple control screws 37 being uniformly rotatably connected to multiple control slides on the disc base 29, and multiple clamping arm units 31 being slidably connected to the multiple control slides and threadedly connected to the multiple control screws 37 one by one, so that they synchronously approach or move away from the center of the disc base 29 under the transmission control of the multiple control screws 37. The clamping controller 30 is very easy to operate. Rotating the control worm 32 causes the control worm 32 to mesh with the control worm wheel 33, which in turn drives the control shaft 34 to rotate. The control shaft 34 then drives the control bevel gear 35 to rotate, which in turn drives multiple linkage bevel gears 36 to rotate. This, in turn, controls multiple control screws 37 to rotate. When the multiple control screws 37 rotate, they can drive multiple clamping arm units 31 to slide within multiple control slides, thereby controlling the multiple clamping arm units 31 to clamp and fix batteries of different sizes. It is preferably suitable for use with cylindrical or prismatic batteries.

[0051] The clamping arm unit 31 includes a clamping arm body 38, which is slidably connected in a control slide. A rotating tube 39 rotatably connected to the clamping arm body 38 is threadedly connected to a control screw 37. A locking screw 40 threadedly connected to the clamping arm body 38 presses against the outer tube surface of the rotating tube 39. Two clamping rollers 41 are rotatably connected to the side of the clamping arm body 38 near the center of the disc seat 29. Insulating rubber sleeves are provided on the roller surfaces of the two clamping rollers 41. A baffle slide is provided in the middle of the clamping arm body 38. A side baffle 42 is slidably connected in the baffle slide. The side baffle 42 is threadedly connected to a manual adjustment screw 43. The manual adjustment screw 43 is rotatably connected to the clamping arm body 38. The side baffle 42 is located between the two clamping rollers 41. When the locking screw 40 threaded on the clamping arm body 38 presses against the outer tube surface of the rotating tube 39, and the rotating tube 39 is relatively fixed to the clamping arm body 38, the control screw 37 can change its contact position with the rotating tube 39 when it rotates, thereby driving the clamping arm body 38 to slide in the control slide through the rotating tube 39, adjusting the overall position of the clamping arm unit 31; the side of the clamping arm body 38 near the center of the disc seat 29 is rotatably connected to two clamping rollers 41, and the roller surfaces of the two clamping rollers 41 are provided with insulating rubber sleeves, which facilitates stable clamping of the lithium battery and reduces wear during clamping of the lithium battery. After the lithium battery is clamped and fixed by multiple clamping arm units 31, one end of the lithium battery is pressed against the insulating rubber buffer pad of the disc seat 29. Then, the hand-adjusting screw 43 on the clamping arm body 38 is rotated to control the side baffle 42 to slide in the baffle slide, so that the side baffle 42 is pressed against the other end of the lithium battery, realizing the limiting and fixing of the lithium battery. A tension spring is fitted on the control screw 37, and the two ends of the tension spring are connected to the clamping arm body 38 and the inner side of the control slide, respectively, to improve the stability of the side baffle 42 pressing against the lithium battery.

[0052] One end of each of the two hinge shafts 25 is fixedly connected to a shock-absorbing gear 44. The two shock-absorbing gears 44 mesh with each other on the rack teeth on both sides of the shock-absorbing slide 45. The top plate of the shock-absorbing slide 45 is slidably connected to the middle of the square rod 46. The upper and lower ends of the square rod 46 are fixedly connected to the side of the receiving seat 24 through rod seats. One or more rod seats are fixedly connected to the top plate with spring shock absorbers 47, which are sleeved on the square rod 46. The reinforcing slide column 48 fixedly connected to the bottom of the shock-absorbing slide 45 slides in the reinforcing slide rail of the mounting seat 21.

[0053] Since the two hinge shafts 25 are rotatably connected to the bottom of the support body 24, and the middle of the two hinge shafts 25 is fixedly connected to the two shock-absorbing brackets 26, when the support body 24 moves up and down, the two hinge shafts 25 rotate to a certain extent as the two shock-absorbing brackets 26 swing. The rotation of the two hinge shafts 25 can drive the two shock-absorbing gears 44 to rotate. The rotation of the two shock-absorbing gears 44 can drive the shock-absorbing slide 45 to slide up and down on the square rod 46 through the meshing of the rack teeth on both sides of the shock-absorbing slide 45, thereby compressing or stretching the spring shock absorber 47 and improving the shock absorption effect. In addition, the reinforcing slide column 48 fixed to the bottom of the shock-absorbing slide 45 slides in the reinforcing slide of the mounting body 21, improving the stability of the relative movement of the shock-absorbing slide 45 and the mounting body 21.

[0054] The worm gear structure on the outer side of the disc base 29 meshes with the lower end of the vertical worm that slides on the loading stand 19. The middle part of the vertical worm is sealed and rotatably connected to the mounting hole on the top surface of the storage box 6, and the top of the vertical worm is connected to the output shaft of the power motor. When the battery temperature is too high or a fire occurs, the controller controls the spray mechanism 8 to extinguish the fire with liquid nitrogen, and simultaneously controls the power motor to drive the vertical worm to rotate. The rotation of the vertical worm meshes with the worm gear structure on the outer side of the disc base 29, thereby controlling the rotation of the disc base 29. This facilitates the rotation of the lithium battery and allows for uniform spraying at different locations, improving the cooling effect or extinguishing the fire in time. Furthermore, the vertical worm slides on the loading stand 19, ensuring that when the loading stand 19 moves up and down to absorb shock, the vertical worm and the worm gear structure on the outer side of the disc base 29 do not obstruct each other and maintain a stable connection.
