[0002] With the rapid development of the new energy vehicle industry, a large number of used power lithium batteries need to be transported and recycled safely. However, during transportation, used power lithium batteries are easily damaged, leading to electrolyte leakage. The electrolyte is mainly composed of a mixture of alkanes, which is volatile and may ignite or explode upon contact with air, causing safety accidents, economic losses, and serious environmental pollution.

[0003] The current relatively safe method of transportation is to immerse used lithium batteries in water to reduce safety risks, but this method has the following problems:

[0004] 1. Damage to used batteries can lead to electrolyte leakage, causing water pollution and increasing wastewater treatment costs.

[0005] 2. Batteries may produce hydrofluoric acid after being submerged in water, which is highly corrosive to metal equipment, affecting the service life of subsequent crushing and sorting equipment and increasing equipment manufacturing costs.

[0006] 3. Containers cannot effectively prevent the risk of fire and explosion caused by electrolyte evaporation, making it difficult to ensure the safety of the transportation process. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a lithium battery safety transport container with a simple structure that can effectively reduce the risk of combustion and explosion of used power lithium batteries during transportation, while avoiding water pollution caused by water immersion, thus improving transportation safety.

[0008] The technical solution adopted by this utility model is as follows: a container for safe transportation of lithium batteries, including a container body, an inner liner, an air intake device and a control device; characterized in that: the container body is a box-shaped structure with one end open, and a door is hinged at the opening, and a sealing strip is provided between the door and the opening of the container body for sealing; a pressure sensor and an oxygen concentration detector are installed in the inner cavity of the container.

[0009] The enclosure is equipped with an air inlet and an air outlet, both of which are connected to the inner cavity of the enclosure. The air intake device includes an air intake pipe, one end of which is connected to the air inlet, and the other end is connected to a quick connector. An electromagnetic air intake valve is installed on the air intake pipe. The air outlet is connected to one end of an exhaust pipe, which is equipped with an electromagnetic exhaust valve. A pressure sensor, an oxygen concentration detector, an electromagnetic air intake valve, and an electromagnetic exhaust valve are all connected to a control device. The control device is installed on the outer wall of the enclosure.

[0010] Furthermore, the inner surface of the box and the inner end face of the box door are provided with a lining made of PVC; the air inlet is set on the bottom plate of the box, and a manual air inlet valve is also set on the air inlet pipe; the exhaust port is set on the top plate of the box, and a manual exhaust valve is also set on the exhaust pipe.

[0011] Furthermore, it also includes a sound alarm device, which is installed on the outer wall of the enclosure and connected to the control device.

[0012] Furthermore, the bottom of the container is equipped with a grounding device for temporary grounding during transportation and loading / unloading.

[0013] Furthermore, the box body has a rectangular box-shaped structure, with a lifting hole at each of the four corners of the top of the box body for easy lifting; the bottom of the box body has two grooves with rectangular cross-sections, which facilitate the insertion of forklift forks.

[0014] Furthermore, the control device and grounding device are installed inside the control box, which is mounted on the side wall of the box. The side wall of the control box is provided with an air inlet hole and an exhaust hole. The other end of the air inlet pipe passes through the air inlet hole and enters the control box, and the other end of the exhaust pipe passes through the exhaust hole and extends into the control box.

[0018] 1. This utility model has a simple structure and is easy to manufacture.

[0019] 2. The inner surface of the box and the inner end face of the box door of this utility model are provided with an inner lining. The inner lining is made of PVC, which can effectively prevent the electrolyte from corroding the box and prevent the lithium battery from directly contacting the box, causing the box to become charged or generate electric sparks, resulting in an explosion; thus improving the safety of lithium battery transportation and the service life of this utility model.

[0020] 3. The seal between the door and the opening of the box in this utility model creates a closed space inside the box. Furthermore, the box is equipped with an air inlet and an air outlet.
