Description

Technical Field

[0001] This utility model relates to the field of PVC container cover technology, specifically a PVC container cover with a reinforced structure. Background Technology

[0002] PVC container covers are protective coverings for shipping containers. They are primarily made of polyvinyl chloride, a common plastic material with excellent chemical resistance, abrasion resistance, water resistance, and weather resistance, making them ideal for manufacturing container covers.

[0003] For example, CN214826066U discloses "A Protective Cover for Containers". In this device, the cover is placed over the container and a radiative cooling film is provided on the cover. The radiative cooling film achieves cooling through radiative cooling under sunlight, which can effectively reduce the temperature inside the container.

[0004] While the aforementioned container covers have certain advantages in reducing the internal temperature of containers, they still have some drawbacks: the container covers are generally not very strong and provide poor protection for the containers; the containers are covered by manually pulling them, and when a vehicle carrying a container needs to cover it while traveling at high speed, it must be driven to a place where it can be parked to do so. This makes it inconvenient to cover the container in time during rainy weather, allowing water to enter the container and causing water damage to the stored items inside. Utility Model Content

[0036] Fifth, as the screw 53 rotates, it drives the worm 54 to rotate. When the worm 54 rotates, it drives the worm wheel 55 to rotate. When the worm wheel 55 rotates, it drives the fixed rod 56 to rotate. When the fixed rod 56 rotates, it drives the front container cover 57 to rotate, so that the front container cover 57 is unrolled until the front container cover 57 covers the front of the container 1.

[0037] Sixth, after the rainy weather, by controlling motor 1 42 and motor 2 512, the container cover 2 and the front container cover 57 can be stored, so that they no longer cover the container 1.
