Description
Technical Field
The invention belongs to the field of marine machinery, and particularly relates to an underwater horizontal cable guider.
Background
A fairlead is a common type of marine machinery that is used primarily to guide the direction of a rigging (e.g., a wire rope or chain, etc.) disposed on a winch.
A conventional fairlead mainly includes a support welded to a hull and a guide pulley assembly rotatably mounted on the support. Since the conventional fairlead is used on water, the structure of the fairlead is not designed for water resistance, so that the fairlead does not have water resistance. If the conventional fairlead is directly used underwater, many problems occur, such as the welded joint between the pedestal and the hull being corroded by seawater, resulting in the fairlead not being securely mounted on the hull.
