[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.
[0028] Please refer to the reference. Figures 1 to 4 This utility model embodiment provides a battery pack recycling device (not shown) for recycling battery pack 200. It can promptly extinguish fires in the event of spontaneous combustion of the battery pack 200, achieving safe temporary storage of the battery pack 200 and preventing safety accidents, thus demonstrating strong safety.
[0029] It should be noted that the battery pack recycling equipment includes a safety temporary storage device 100 and a recycling device (not shown in the figure). The safety temporary storage device 100 and the recycling device are arranged sequentially. After the damaged battery pack 200 is placed on the pallet 300 manually or using a robotic arm, a forklift or stacker truck is used to transport the pallet 300 and the battery pack 200 on it to the safety temporary storage device 100. The safety temporary storage device 100 is used to temporarily store the battery pack 200. When the time is right, a forklift or stacker truck is used to remove the pallet 300 and the battery pack 200 from the safety temporary storage device 100 and send them to the recycling device. The recycling device is used to disassemble and recycle the battery pack 200.
[0030] The safety-type temporary storage device 100 includes a temporary storage rack 110, a fire sensor 120, an electrical control box 130, a conveying mechanism 140, and an explosion-proof water tank 150. The temporary storage rack 110 has a temporary storage cavity 111, and the conveying mechanism 140 is installed within the temporary storage cavity 111 for placing the battery pack 200. The fire sensor 120 is installed within the temporary storage cavity 111 and electrically connected to the electrical control box 130, which is also electrically connected to the conveying mechanism 140. The temporary storage cavity 111 has a clearance opening 112, and the explosion-proof water tank 150 is located on one side of the temporary storage rack 110, below the clearance opening 112. Specifically, the fire sensor 120 sends a control signal to the control box 130 when it detects a fire in the battery pack 200 within the temporary storage cavity 111. The control box 130 then controls the conveying mechanism 140 to deliver the battery pack 200 through the discharge port 112, allowing it to fall into the explosion-proof water tank 150. The explosion-proof water tank 150 contains fire extinguishing liquid to extinguish the fire in the battery pack 200. This allows for timely fire suppression in the event of spontaneous combustion of the battery pack 200, ensuring its safe temporary storage and preventing accidents, thus enhancing safety.
[0031] The conveying mechanism 140 includes a drive assembly 141 and multiple conveying rollers 142. The multiple conveying rollers 142 are arranged in parallel at intervals and are rotatably mounted within the temporary storage cavity 111. The multiple conveying rollers 142 work together to support the tray 300 and the battery pack 200 on it. Specifically, the drive assembly 141 is simultaneously connected to the multiple conveying rollers 142, and the drive assembly 141 can synchronously drive the multiple conveying rollers 142 to rotate, thereby moving the tray 300 and the battery pack 200 on it, causing them to pass through the clearance opening 112 and fall into the explosion-proof water tank 150.
[0032] The drive assembly 141 includes a drive motor 1411, a drive sprocket 1412, a chain 1414, and multiple driven sprockets 1413. The drive motor 1411 is mounted on the temporary storage rack 110 and connected to the drive sprocket 1412. The drive sprocket 1412 is simultaneously connected to multiple driven sprockets 1413 via the chain 1414. Each driven sprocket 1413 is connected to a conveyor roller 142. The drive motor 1411 drives the drive sprocket 1412 to rotate, thereby synchronously driving the multiple driven sprockets 1413 to rotate via the chain 1414, and thus synchronously driving the multiple conveyor rollers 142 to rotate, achieving the conveying function.
[0033] Optionally, there are multiple temporary storage cavities 111 and multiple conveying mechanisms 140. The multiple temporary storage cavities 111 are arranged sequentially in a vertical direction, and each conveying mechanism 140 is disposed in one temporary storage cavity 111. Each temporary storage cavity 111 is used to accommodate one battery pack 200. Specifically, the multiple temporary storage cavities 111 and multiple conveying mechanisms 140 work together to simultaneously realize the temporary storage of multiple battery packs 200, thereby improving the temporary storage efficiency. Since the multiple temporary storage cavities 111 are arranged sequentially in a vertical direction, the battery pack 200 in each temporary storage cavity 111 can pass through the clearance opening 112 and fall into the explosion-proof water tank 150 under the action of its corresponding conveying mechanism 140.
[0034] In this embodiment, there are three temporary storage cavities 111 and three conveying mechanisms 140 to temporarily store three battery packs 200 simultaneously. However, this is not the only embodiment. In other embodiments, there may be five or eight temporary storage cavities 111 and eight conveying mechanisms 140. The number of temporary storage cavities 111 and eight conveying mechanisms 140 is not specifically limited.
[0035] The temporary storage rack 110 includes a support bracket 113, a temporary storage box 114, and multiple partitions 115. The temporary storage box 114 is connected to the support bracket 113 and is positioned above the support bracket 113. The support bracket 113 supports and secures the temporary storage box 114. An explosion-proof water tank 150 is positioned on one side of the support bracket 113. Multiple partitions 115 are spaced vertically and connected to the temporary storage box 114 to divide the temporary storage box 114 into multiple independent temporary storage cavities 111, thereby facilitating the independent temporary storage of multiple battery packs 200.
[0036] In this embodiment, both the temporary storage box 114 and the partition 115 are made of fireproof material to prevent the battery pack 200 in one temporary storage cavity 111 from catching fire and causing damage to the battery pack 200 in other temporary storage cavities 111.
[0037] Optionally, the temporary storage cavity 111 is also provided with an inlet and outlet 116. The inlet and outlet 116 and the clearance opening 112 are arranged opposite to each other on both sides of the temporary storage cavity 111. The inlet and outlet 116 is used for the normal delivery or removal of the battery pack 200. That is, in the absence of a fire in the battery pack 200, a forklift or stacker truck can be used to deliver or remove the pallet 300 and the battery pack 200 on it into or out of the temporary storage cavity 111 through the inlet and outlet 116.
[0038] In this embodiment, the fire sensor 120 is a smoke sensor. The fire sensor 120 determines whether the battery pack 200 is on fire by detecting the smoke concentration in the temporary storage cavity 111. However, it is not limited to this. In other embodiments, the fire sensor 120 can be a temperature sensor or a vision sensor. The type of fire sensor 120 is not specifically limited.
[0039] Optionally, multiple fire sensors 120 are provided, spaced apart and distributed at different locations within the temporary storage cavity 111, to ensure the accuracy of fire detection and prevent false alarms. Specifically, all fire sensors 120 are electrically connected to the electrical control box 130, and are divided into multiple groups, with each group of fire sensors 120 located within a temporary storage cavity 111, to simultaneously detect fires in multiple battery packs 200.
[0040] The explosion-proof water tank 150 includes a tank body 151, a lid 152, and a spring hinge 153. The lid 152 is mounted on the tank body 151 and connected to the tank body 151 via the spring hinge 153. The lid 152 can rotate relative to the tank body 151 to open or close the tank body 151. Specifically, under normal circumstances, the lid 152 will remain closed under the elastic force of the spring hinge 153. The lid 152 is used to overcome the elastic force of the spring hinge 153 when the battery pack 200 falls and rotate downward to open the tank body 151, so that the battery pack 200 can fall into the tank body 151. After the battery pack 200 falls into the tank body 151, the spring hinge 153 is used to drive the lid 152 upward to reset and close the tank body 151 under its own elastic force, preventing flames from escaping and further improving safety.
[0041] Optionally, a soft fire-resistant layer (not shown) is provided inside the housing 151 to prevent the battery pack 200 from exploding due to hard impact with the inner wall of the housing 151. The soft fire-resistant layer has good fire resistance and is safe and reliable.
[0042] Optionally, the bottom of the housing 151 is provided with casters 154 to facilitate the removal and disposal of the battery pack 200 from the scene after the fire is extinguished.
[0043] The safety temporary storage device 100 provided in this embodiment of the utility model includes a temporary storage rack 110 with a temporary storage cavity 111, a conveying mechanism 140 installed in the temporary storage cavity 111 for placing a battery pack 200, a fire sensor 120 installed in the temporary storage cavity 111 and electrically connected to an electrical control box 130, which is also electrically connected to the conveying mechanism 140, a clearance opening 112 in the temporary storage cavity 111, and an explosion-proof water tank 150 located on one side of the temporary storage rack 110 and below the clearance opening 112. The fire sensor 120 sends a control signal to the electrical control box 130 when it detects a fire in the battery pack 200 in the temporary storage cavity 111. The electrical control box 130 controls the conveying mechanism 140 to send the battery pack 200 out of the clearance opening 112 so that the battery pack 200 falls into the explosion-proof water tank 150, which is used to hold fire extinguishing liquid. Compared with existing technologies, the safe temporary storage device 100 provided by this utility model, due to the adoption of a conveying mechanism 140 installed in the temporary storage cavity 111 and an explosion-proof water tank 150 set on one side of the temporary storage rack 110, can promptly extinguish fires in the event of spontaneous combustion of the battery pack 200, achieving safe temporary storage of the battery pack 200, avoiding safety accidents, and providing strong safety. This makes the battery pack recycling equipment safe and reliable, with good recycling results.
[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
