The invention provides a seabed anchor chain tensioner which comprises a movable anchor chain with the two ends used for being connected with an anchor and a first collecting and releasing device of a working ship correspondingly, a driving cable with one end used for being connected with a second collecting and releasing device of the working ship, an outer frame, an anchor chain wheel and a linkage rod set, the other end of the fixing anchor chain is connected with the external frame; a through opening formed in the bottom end and an anchor chain groove used for containing an anchor chain wheel are formed in the outer frame, a first anchor chain channel is formed between the anchor chain groove and the anchor chain wheel, and the first anchor chain channel is communicated with the through opening; the movable anchor chain sequentially penetrates through the through opening, the first anchor chain channel and the linkage rod set. The linkage rod set comprises a pawl part, the cable lifter comprises a ratchet wheel, and the driving cable is in transmission connection with the linkage rod set. The problems that existing offshore floating equipment is too high in manufacturing cost and maintenance cost, and oil spilling risks are caused by an anchor gear and power equipment of the offshore floating equipment are solved.
本发明提供一种海底锚链张紧器,包括两端用于分别连接锚和工作船第一收放装置的活动锚链、一端用于连接工作船第二收放装置的驱动缆、外部框架、以及都可转动地安装在外部框架上的锚链轮及联动杆组,所述固定锚链的另一端与外部框架相连;所述外部框架中开设有设置于底端的贯通口和用于容置锚链轮的锚链槽,所述锚链槽和锚链轮之间形成第一锚链通道,所述第一锚链通道与贯通口相通;所述活动锚链依次穿过贯通口、第一锚链通道和联动杆组;所述联动杆组包括棘爪部,所述锚链轮包括棘轮,所述驱动缆与联动杆组传动连接。本发明解决了现有海上浮式设备的制造成本和维护成本过高以及由自带的锚机及动力设备而带来的溢油风险的问题。
