In the production of ultra-thin float glass, the glass forming process is carried out in the annealing kiln. The annealing kiln is generally divided into an insulation section and a non-insulation section. The insulation section is a closed slow cooling zone that eliminates the permanent stress and most of the temporary stress in the glass. The non-insulation section is an open rapid cooling zone. The open non-insulation section is affected by the external temperature, which may cause the glass to explode. Utility Model Content

[0005] There are multiple protective plates, which are connected together by connecting components to form a closed device. The protective plates include an outer shell and an insulating lining. The outer shell is two plate-like structures of the same size and shape, and an insulating lining is provided between the two outer shells.

[0006] The connecting components include buckles and snaps, which are respectively arranged on two adjacent protective plates, and the adjacent protective plates are connected as a whole through the cooperation of the buckles and snaps.

[0007] An emergency door is arranged in the enclosing device, and the emergency door is arranged on a protective plate in the middle section of the enclosing device through a hinge.

[0008] A flexible curtain is arranged in the gap between the bottom of the enclosing device and the ground.

[0009] The caster is a universal wheel with a self-locking function.

[0010] The beneficial effects of the utility model are: the device has a simple structure, low manufacturing cost, convenient assembly and disassembly, and effectively prevents the non-insulation section from being affected by the external temperature, thereby causing the glass to explode, thereby improving the yield rate and quality of finished products of glass production.
