The invention discloses an adjustable expansion protective sleeve suitable for a ship fairlead, which is characterized in that a through conical mounting groove is formed in the protective sleeve, a conical expansion plate is connected to the mounting groove in a matching way, the appearance of the expansion plate is consistent with that of the protective sleeve, the conical mounting groove in the protective sleeve and the expansion plate can be matched for expansion mounting, and the protective sleeve is sleeved inside the fairlead. The expansion plate penetrates into the mounting groove from the narrow end and continuously penetrates into the mounting groove along with the expansion plate, so that expansion fixed mounting of the protective sleeve is realized, the deeper the expansion plate enters the mounting groove, the higher the mounting firmness of the protective sleeve is, displacement of the protective sleeve under the action of pulling force is prevented, and the shrinkage effect of the protective sleeve caused by climate reasons is counteracted; and the installation and use safety of the protective sleeve is improved.

    本发明公开了一种适用于船舶导缆孔的可调整胀紧保护套,保护套上设有贯通的锥形安装槽,安装槽配套连接设有锥形胀紧板,胀紧板外形与保护套外形相符,保护套上锥形的安装槽与胀紧板可配套胀紧安装,将保护套套设于导缆孔内部,将胀紧板由窄端穿入安装槽,随着胀紧板不断深入安装槽内部,实现了保护套的胀紧固定安装,胀紧板进入安装槽深度越深保护套的安装牢固性越高,防止了保护套在拉力作用下产生位移,及抵消了由于气候原因造成的保护套收缩效应,提高了保护套安装及使用的安全性。
