When the cable needs to be lifted, the joint connected with the cable 5 is lifted by the lifting mechanism 7, and the cable collecting cone 2 is released in the positive direction to release the joint connected with the cable 5. After the target ship receives the joint, the cable collecting cone 2 can be controlled to continue to release. The joint connected with the cable 5 enters the deck through the cable guide groove 6 and is used.

[0035] When the cable needs to be stored, the joint connected with the cable 5 is stored in the reverse direction by the cable collecting cone 2. First, the excess on the deck is stored. When the joint is close to the limit of the lifting mechanism 7, the lifting mechanism 7 is lowered. The joint connected with the cable 5 is lowered by the lifting mechanism 7.

The height signal is transmitted to the controller to determine the length of the lifting mechanism 7. The controller starts the lifting mechanism 7 and the cable collecting cone 2. The tension sensor collects the tension signal of the cable during the process and feeds it back to the controller to control the rotation speed of the cable collecting cone 2. When the tension exceeds the specified value, the speed is increased to relax the cable and accelerate the release. When the tension is less than the specified value, the speed is reduced to tighten the cable. The joint connected with the cable 5 is lifted by the lifting mechanism 7, and the joint connected with the cable 5 is released in the positive direction by the cable collecting cone 2. Until the specified height is reached, the controller stops the lifting mechanism 7 and the cable collecting cone 2.
