Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a shaft waterproof cover of a standard ship type and the ship. Background Art

[0002] A shaft waterproof sleeve is a device used to protect the shaft from moisture intrusion. It is usually used in places where waterproofing is required, such as ships and mechanical equipment. Its function is to prevent moisture from entering the shaft, thereby protecting the shaft from normal operation and avoiding damage or malfunction caused by moisture intrusion.

[0003] Existing shaft waterproofing sleeves typically consist of rubber sealing rings installed at the front and rear joints of the bearings, forming one or more waterproof barriers. However, while existing shaft waterproofing sleeves can protect the shaft from water intrusion to a certain extent, they also have some shortcomings. For example, the manufacturing and installation process of the rubber sealing rings is relatively complex, which increases the difficulty of system assembly and maintenance. The rubber material may degrade over time or in certain environments such as high and low temperatures, acid and alkali corrosion, resulting in a reduced sealing effect, which in turn affects the safety and reliability of the shaft system.
