The invention relates to the technical field of ships, and discloses a variable-inner-diameter cavel single-roller fair lead for ship, the fair lead comprises a base and an adjusting assembly, and a fairlead cavel is fixedly mounted on the right side of the top of the base; the variable-inner-diameter cavel single-roller fair lead can drive an outer pipe to move through stretching of an electric telescopic rod. An inner rod and a fixing block move along with a rotating shaft, a connecting rod is turned over under the action of the connecting rod and pushes a moving head to move, when the fixed head moves to an extreme value and cannot move, the outer pipe still continues to move, so that a turning rod is turned over, and under the extrusion action of the turning rod, two extrusion plates move towards the opposite sides. In the process, a constant-pressure rod always keeps a counter-acting force, then the extrusion plate exerts the pressure on the elastic plate, the elastic plate is expanded outwards, the inner diameter of the fair lead is changed to a certain degree, and then the situation that the cable falls off can be effectively avoided through the change of the inner diameter.

    本发明涉及船舶技术领域,且公开了一种船舶上所用可变内径的羊角单滚轮导缆器,包括底座和调节组件,所述底座顶部右侧固定安装有导缆羊角,该船舶上所用可变内径的羊角单滚轮导缆器,通过电动伸缩杆的拉伸可带动外管进行移动,内杆与固定块也随之进行移动,连接杆在其作用下进行翻折,并推动移动头进行移动,当固定头移动至极值故而无法进行移动,外管仍继续移动,从而使得翻折杆进行翻折,在翻折杆的挤压作用下,两个挤压板向相背一侧进行移动,过程中恒压杆始终保持反作用力,接着挤压板对弹性板产生压力,使得弹性板向外扩展,从而使得导缆器的内径产生一定变化,进而达到了可通过内径改变有效避免缆绳脱落的情况。
