Description

Fairlead Sheet for Heat-Insulating Vessels The present invention relates to the field of ship fairlead device technology, and in particular to a heat-dissipating ship fairlead sheet. A fairlead, also known as a bulwark chock, is a closed-hole fairlead installed in a bulwark to restrict the exit position of a cable; it is a circular or elliptical ring casting. Fairleads are generally manufactured from cast iron or cast steel and are mounted in a bulwark to guide a hawser through the hull, preventing the hawser from damaging the hull. As such, they are widely applied in mooring in marine engineering and are an essential device in marine engineering. After prolonged use of a hawser in a fairlead, the hawser is prone to breaking due to wear, which can lead to accidents. Therefore, a fairlead sheet is generally installed inside the fairlead to reduce cable wear and prevent cable breakage accidents. Patent No. 2023226535055 is a ship fairlead sheet comprising an inner bulwark member and an outer bulwark member, wherein the inner bulwark member and the outer bulwark member comprise a wide end having a wide cross-section and a narrow end having a narrow cross-section, and a parabolic outer wall is installed between the wide end and the narrow end, and a central bulwark ring is installed between the inner bulwark member and the outer bulwark member, and the left and right ends of the central bulwark ring are integrally joined to the narrow end of the inner bulwark member and the narrow end of the outer bulwark member, respectively. The joint seam formed by the connection between the central bulwark ring of the present application, the narrow end of the inner bulwark member, and the narrow end of the outer bulwark member is located on both the left and right sides of the narrowest position of the sheet, and the narrowest position of the sheet is composed of the complete structure of the central bulwark ring, thereby improving the structural strength of the narrowest position of the fairlead sheet, reducing wear of the narrowest position of the fairlead sheet, and improving the service life of the fairlead sheet. However, the fairlead sheet comes into prolonged contact with the cable, causing friction. This friction between the cable sheets generates heat and static electricity, which are not efficiently dissipated or conducted, causing the cable to fuse easily. Additionally, since the sheet is installed on the outer side of the fairlead and withstands the large external force of the cable, the sheet is easily damaged. Therefore, in actual applications, there is a need for heat-dissipating marine fairlead sheets that can effectively dissipate heat, absorb static electricity, and possess high load-bearing capacity.
