Multi-fan floating system moored by soft rigid arm

Abstract

The invention discloses a multi-fan floating system moored by soft rigid arm. The system is characterized in that a rotating tower is arranged on a fixed structure and can freely rotate around the vertical axis of the fixed structure, the front end of a yoke frame is connected with the rotating tower through a universal joint, the rear end of the yoke frame is hinged to the bottom end of a mooringleg through the universal joint, a ballast weight is arranged on the yoke frame, the top of the mooring leg is connected to the front end of the mooring support through the universal joint and a thrust bearing, the mooring support is fixed to the front end of a floating type draught fan foundation, a dynamic cable is installed between the floating type draught fan foundation and the rotating control tower, and two draught fan towers are arranged at the rear end of the floating type draught fan foundation, and a wind turbine generator is arranged at the top of each fan tower. The system is simple in structure, stable in operation, low in investment and construction cost, high in floating foundation constraint force and capable of limiting the movement of the floating fan under the environmental load, so that the floating fan has stable windage performance, and the power generation efficiency is further improved.

Description

technical field [0001] The invention belongs to the field of marine renewable energy, and in particular relates to a shallow-water multi-fan floating system moored by soft rigid arms. Background technique [0002] After 30 years of development and exploration, offshore wind power technology has been improving and the development cost of offshore wind farms has been decreasing. The development of offshore wind power has become one of the main forms of development and utilization of new energy technologies. The available space in the ocean has more potential than that on the land. In addition, the ocean wind energy resources are more abundant and stable than the land, and the offshore wind farms are usually far from the shore, and the visual pollution is almost negligible. Therefore, the ocean wind power still has a relatively broad space for development in the future. . [0003] At present, marine wind turbines are developing in the direction of large-scale, high-power, batc...

AI Technical Summary

Problems solved by technology

At present, the water depth of floating wind turbines is tens of meters to 100 meters, and the floating foundation moves greatly in shallow water waves. The traditional catenary mooring cables need a large length in shallow water to provide the floating foundation. The recovery force of the floating wind turbine needs to be extremely high and a large number of mooring lines are required to constrain the movement of the floating wind turbine. The investment and construction cost of this mooring system is too high
