Split type floating fan base and floating fan

Abstract

The invention provides a split type floating fan base and a floating fan. The split type floating fan base comprises a first buoy, a plurality of second buoys, a connecting rod, a plurality of suspension cables and a balance weight part. The volume of the first buoy is greater than that of the second buoy; the first buoy is provided with a connecting assembly used for being connected with a draught fan. The second buoys are connected with the first buoy through connecting rods; the plurality of second buoys are distributed at equal intervals and are rotationally and symmetrically distributed, and the first buoy is located at the central position of the plurality of second buoys; and each second buoy is connected with the counter weight through a suspension cable. According to the split type floating fan base, on the basis of the configuration of the large first buoy and the multiple small second buoys and the structure that the bottoms of the multiple second buoys are connected with the balance weight pieces, the effect that the waterline area is small but large restoring torque can be provided is achieved, the whole split type floating fan base has excellent stability, small enough pitching and rolling freedom degree dynamic response can be kept, and arrangement of the floating fan is facilitated.

Description

technical field [0001] The invention relates to the structural field of fan bases, in particular to a split-type floating fan base and the floating fan. Background technique [0002] Today, energy and environmental crises are becoming increasingly severe. Human beings urgently need to increase the development of clean and renewable energy to achieve the requirements of sustainable development. With the maturity of wind power technology and the continuous decline of costs, wind power generation has become one of the most widely used new energy power generation methods. And studies have shown that the wind energy that can be developed and utilized in my country's offshore is about 750 million kw, which is three times that of onshore wind energy, and the offshore wind energy reserves are more abundant. Therefore, marine wind energy will be one of my country's important new energy sources. At the same time, the southeast coastal area with the most abundant offshore wind energy...

Problems solved by technology

On the other hand, the drilling and oil riser of the offshore platform cannot withstand large vertical deformation, so it is very important to suppress the heave motion, and the swing has little impact on the safe operation of the platform; The hydrodynamic requirements of the base platform are exactly the opposite. The heave motion has little effect on the energy harvesting of the wind turbine, but the swing has a great influence. Only by keeping the dynamic response of the pitch and roll degrees of freedom small enough can the efficient operation of the wind turbine be guaranteed.
