Abstract

The invention relates to a semi-submersible type fan foundation and a semi-submersible type fan, the semi-submersible type fan foundation comprises three vertical stand columns and three horizontal buoyancy tanks, the three vertical stand columns are respectively located at the positions of three corners of a regular triangle, each horizontal buoyancy tank is connected with the bottoms of two adjacent vertical stand columns, a ballast tank and a channel are arranged in each horizontal buoyancy tank; an apron board is located on the outer edge of each horizontal buoyancy tank and horizontally extends outwards; a supporting rod assembly is used for connecting one vertical stand column and one horizontal buoyancy tank; and the three sets of mooring cables correspond to the three vertical stand columns one to one, one end of each set of mooring cable is connected with the bottom of the corresponding vertical stand column, and the other end of each set of mooring cable is connected with a mooring anchor anchored to the seabed. The semi-submersible type draught fan comprises a draught fan assembly and the semi-submersible type draught fan foundation, and the draught fan assembly is installed on the draught fan foundation. The semi-submersible fan foundation and the semi-submersible fan are good in structural stability, good in water depth adaptability and low in manufacturing cost.

Description

technical field [0001] The invention relates to the field of marine engineering and offshore wind power generation systems, in particular to a semi-submersible floating fan foundation and a semi-submersible floating fan. Background technique [0002] At present, in the field of offshore wind power, floating wind turbines, as important equipment for offshore wind power development, have received widespread attention and have been put into commercial production. [0003] The foundations of floating wind turbines usually include single column type, tension leg type, barge type, semi-submersible type, etc. The single-column foundation has good motion performance and stability, but the installation is complicated and the water depth adaptability is poor; the tension leg foundation has good performance, but the installation is complicated, the overall cost is high, and the technology is difficult; the barge foundation has low investment but low motion performance. Poor, poor adap...
