The two ends of the spring are respectively connected to the first and second chain stoppers. The working principle of the design is to obtain the anchor chain tension according to the pressure signals of the first and second pressure sensors. When the anchor chain tension is less than the limit value, the retractable end of the chain stopper cylinder is controlled to retract. The first and second chain stoppers hold the anchor chain tightly under the action of the spring. When the anchor chain tension reaches the limit value, the retractable end of the chain stopper cylinder is controlled to extend, driving the first and second chain stoppers to open, loosening the anchor chain to ensure the safety of the ship. Therefore, the present invention can loosen the anchor chain when the anchor chain tension reaches the limit value to ensure the safety of the ship. BRIEF DESCRIPTION OF THE DRAWINGS
