[0002] Among nuclear power marine engineering equipment, icebreakers are relatively important engineering equipment. When performing icebreaking operations, rotating shaft components will generate relatively large heat during use. Rotating shaft components usually need to be connected and fastened with a variety of different fastening components during installation. Since the vertical fastening components are directly matched with the plane when fitting, the space at the connection position is tight, and the high temperature resistance during use is relatively poor. High temperature will affect the durability of the fastening components, resulting in a relatively low service life during use. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-temperature resistant fastening protection component for icebreakers. By arranging a 63-degree inclined slope structure in the vertical direction of the installation position of the rotating shaft component, it can provide a certain safe ventilation space between different components when they are matched. The precise stop groove at the bottom position can ensure the overall installation accuracy, and the high-temperature resistance of the protection component can be made more reliable when in use. The reinforced connection groove at the right position during installation can ensure the stability of the installation position. When tightening the whole, it only needs to be tightened with a fastening bolt at one position. The overall installation efficiency is higher, the installation operation is more convenient, and the installation combination cost is lower.
