Description

Technical Field

[0001] This utility model relates to the field of lithium battery-containing goods transportation technology, and in particular to a fire-retardant and explosion-proof cover. Background Technology

[0002] With the rapid rise of e-commerce platforms, the demand for lithium battery-containing goods (such as electronic products, backup power supplies, and power banks) in people's daily lives is surging, and the volume of lithium battery-containing goods being transported is also continuously expanding. However, lithium battery-containing goods may burn or explode during transportation due to thermal runaway such as short circuits, compression, or high temperatures, threatening transportation safety. Therefore, the transportation of lithium battery-containing goods requires professional packaging or transportation methods.

[0003] Current methods for transporting goods containing lithium batteries also utilize pallets, which significantly increases the risk of combined fires caused by pallets being mixed with ordinary flammable materials (such as cardboard boxes, foam, and textiles). Current transport methods involve packing lithium battery-containing goods into cardboard boxes or other packaging, placing the boxes on transport pallets, securing them with mesh bags, and then transporting them by air. Under conditions of overcharging, short circuits, overheating, punctures, or collisions, thermal runaway can occur, easily leading to fires or even explosions. To address these issues, there is a need to develop specialized fire-resistant equipment for air transport of lithium battery-containing goods, such as fireproof and explosion-proof transport boxes and fireproof and explosion-proof covers. Current technology focuses on fireproof transport boxes, using special fireproof materials to manufacture transport boxes for transporting lithium battery-containing goods. However, the high cost of these transport boxes prevents large-scale application. Fireproof and explosion-proof covers are used for packaging on freight pallets, are convenient to use, and low in cost. Currently, there are no dedicated fireproof and explosion-proof covers for air transport pallets. Therefore, this product is being developed to prevent safety accidents caused by uncontrolled fires of lithium battery-containing goods, thus more effectively ensuring the safety of cargo transportation. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fireproof and explosion-proof cover with a simple structure, which has excellent flame retardant properties to prevent the spread of fire, can maintain structural integrity under extreme temperatures, and plays a role in flame retardancy and explosion protection. At the same time, it also has good high temperature resistance and heat insulation properties, and is suitable for the transportation of lithium batteries, electronic products and flammable products, especially air transport, to ensure transportation safety.

[0020] Figure 1 This is a schematic diagram of the structure of the fire-retardant and explosion-proof cover according to an embodiment of the present invention. A fire-retardant and explosion-proof cover includes a top cover 1, a base 2, and a barrier 3. The barrier 3 is disposed between the top cover 1 and the base 2.

The front and rear sides of the barrier 3 are provided with flame-retardant strips 5, and the flame-retardant strips 5 are provided with several metal rings 4 for fixing ropes 7. The barrier 3 is fixed to the cargo by the metal ropes 7. The top cover 1 and the base 2 are fixedly connected by ropes 7.

[0021] The top cover 1 and the base 2 are rectangular structures of the same size, each consisting of three layers: a first flame-retardant layer 1-1, a flame-retardant and heat-insulating layer 1-2, and a second flame-retardant layer 1-3. The first flame-retardant layer 1-1 and the second flame-retardant layer 1-3 are preferably made of gray high-silica cloth with a thickness of 0.3-0.5 mm. The flame-retardant and heat-insulating layer 1-2 is preferably made of alumina felt with a thickness of 6-10 mm. The enclosure 3 consists of a first explosion-proof flame-retardant layer 3-1, a heat-insulating layer 3-2, and a second explosion-proof flame-retardant layer 3-3. The first explosion-proof flame-retardant layer 3-1 and the second explosion-proof flame-retardant layer 3-3 are preferably made of orange high-silica cloth with a thickness of 0.3-0.5 mm. The heat-insulating layer 3-2 is preferably made of carbon felt with a thickness of 2-5 mm.

[0022] The procedure for using this device is as follows: First, place the base 2 on a freight pallet. Stack the boxes containing lithium batteries on the pallet. After all the boxes are sealed, use the enclosure 3 to surround the boxes, wrapping them tightly and securing them with Velcro 6. Then, use steel wire ropes to lock and secure the enclosure through the metal rings 4 fixed to the flame-retardant strips 5. After securing, place the top cover 1 on the enclosure 3, and use ropes 7 to secure the top cover 1 and base 2 in a Z-shaped binding method through the metal rings 4, thus wrapping the enclosure 3. The middle layer of the enclosure 3 is essentially composed of six layers, enhancing the impact resistance of the fireproof and explosion-proof cover. Finally, seal the enclosure with a freight net.
