Rotatable buoyancy fan foundation

Abstract

The invention discloses a rotatable buoyancy fan foundation, which belongs to the technical field of wind power generation, and comprises a wind direction detection system, a floating system for supporting a wind power generation tower, a deflection system for controlling a floating device to rotate, and a positioning system for positioning the floating system, the deflection system comprises at least three propellers, the propellers are arranged on concentric circles with the center of the floating system as the circle center, the propellers are fixedly arranged at the bottom of the floating system, and the included angles between the propelling directions of the propellers and the concentric circles are the same; the wind direction detection system detects the wind direction, the deflection system starts the propeller, the floating system and the wind power generation tower are controlled to rotate to the windward position, and positioning is conducted through the positioning system. According to the device, the foundation can be controlled to rotate, the buoyancy fan can conduct wind alignment conveniently, control is simple and stable, and the design and maintenance cost is saved.

Description

technical field

[0001] The invention belongs to the technical field of wind power generation, and in particular relates to a rotatable buoyancy fan foundation. Background technique

[0002] The direction of the wind is constantly changing with time, and the wind turbine must face the wind direction to maximize the efficiency of the use of wind energy. Therefore, the nacelle of the wind turbine must also change its direction continuously following the change of the wind direction to ensure that it is always in the windward state. The traditional The problem can be solved by setting the yaw system for land wind turbines, but for buoyancy wind turbines, the use of this system makes the overall device structure and control more complicated, and the instability of the buoyancy foundation is likely to affect the accuracy of the wind, thus greatly increasing costs. Contents of the invention

[0003] In view of this, the purpose of the present invention is to provide a rotatable ...
