Description

Technical field The present application relates to the technical field of marine fairlead devices, in particular to a heat dissipation type marine fairlead protective sleeve. Background art A fairlead, also known as a bulwark chock, is a closed-hole fairlead installed on a bulwark to limit the cable lead-out position, which is a circular or elliptical annular casting. The fairlead is usually made of cast iron or cast steel and installed on the bulwark to guide the cable through the hull and prevent the cable from damaging the hull. It is widely used in the mooring of ships and marine engineering and is an essential device for ships and marine engineering. After prolonged use of the cable in the fairlead, it is easy to cause the cable to break due to wear and tear, causing accidents. Generally, a fairlead protective sleeve is arranged in the fairlead, which can reduce the wear of the cable and avoid the occurrence of cable breakage accidents. The fairlead protective sleeve and a hawser, namely the cable, are in long-term frictional contact, and that the friction between the cable and the protective sleeve generates heat and static electricity which cannot be efficiently dissipated and conducted, which may cause the cable to melt easily. In addition, the protective sleeve is arranged on the outer side of the fairlead, and the protective sleeve bears the huge external force of the cable, which makes the protective sleeve easily damaged and broken.
