Abstract: A floating breakwater and wind energy integrated system used for offshore aquaculture. The system contains the wind turbine system, the floating breakwater system, and offshore aquaculture system. The combination of wind turbine, floating breakwater system and offshore aquaculture system makes full use of the floating breakwater, thus decrease the wave load on the floating cage. In addition, the floating breakwater offers a supporting platform to the floating wind turbine, which effectively reduces the costs of the wind turbine. Meanwhile, a power autarkic offshore aquaculture system may be realized by using the electrical energy generated by the turbine. Compared with the simple offshore aquaculture system, the utilization rate of the sea per unit becomes even higher while the costs of the floating wind turbine becomes even lower.

Abstract: A crane extension and installation device includes an extension device, a winch, a pulley and a cable. A main arm includes a vertical slide rail, the main arm is inclined relative to vertical, and three second pulleys at different heights of the slide rail are installed in the vertical direction of the slide rail, and the second pulley can slide vertically along the slide rail and can be fixed at a certain position of the slide rail. The extension device includes a number of cantilever beams connected end to end. The front end of the extension device is a cantilever beam, and a fixed pulley is installed on the lower peripheral surface of the extension device. The end face of the cantilever beam is equipped with a vertical lower arm through a joint, and the bottom end of the lower arm has a first pulley fixed by the joint.
