Floating adjusting type wind power system

Abstract

The invention relates to the technical field of offshore wind power, and discloses a floating adjusting type wind power system. The floating adjusting type wind power system can change the weight, improve the stability and prevent an air duct machine from being greatly inclined or abraded. The floating adjusting type wind power system comprises a floating platform provided with a through hole, an air duct machine body arranged in the through hole in a penetrating mode, a connecting rope and a water injection area provided with a water inlet, the air duct machine body is provided with a fan blade power generation assembly and a first buoyancy part; the connecting rope is connected between the air duct machine body and the through hole; and the water injection area is arranged at the first buoyancy part. According to the floating adjusting type wind power system, the air duct machine body can be pulled and limited through the connecting rope, the situation of large-amplitude inclination is prevented, the situation that the outer wall of the air duct machine body is abraded is avoided, the weight of the first buoyancy part can be controlled through the water injection area, the air duct machine body transversely floats on the sea surface when the water injection area is emptied, transportation and transfer are facilitated, the weight of the first buoyancy part can be increased through water injection, and the air duct machine body can sink into the sea and float on the sea surface.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to a floating adjustable wind power system. Background technique [0002] Most of the existing offshore wind power systems use a vertical buoyancy structure, that is, the wind turbine floats in the water by its own buoyancy, and is directly connected to the sinking platform on the seabed through the anchor rope. Due to the effect of traction, under the influence of large waves and sea wind, the blower machine is prone to move, shake or greatly tilt on the sea surface, so the blower machine is likely to be in an unstable state, and the blower machine is in the bottom of the sea. Collision and friction between the outer wall and the anchor rope are easy to cause damage to the outer cylinder of the blower, which will cause seawater to enter the inside of the blower, increase the overall gravity of the blower, and sink. For the buoyancy support of the blower itself, it is n...

[0002] Most of the existing offshore wind power systems use a vertical buoyancy structure, that is, the wind turbine floats in the water by its own buoyancy, and is directly connected to the sinking platform on the seabed through the anchor rope. Due to the effect of traction, under the influence of large waves and sea wind, the blower machine is prone to move, shake or greatly tilt on the sea surface, so the blower machine is likely to be in an unstable state, and the blower machine is in the bottom of the sea. Collision and friction between the outer wall and the anchor rope are easy to cause damage to the outer cylinder of the blower, which will cause seawater to enter the inside of the blower, increase the overall gravity of the blower, and sink. For the buoyancy support of the blower itself, it is necessary to determine the length, cavity volume and counterweight of the blower. Since the main material of the blower body is metal material with a large specific gravity, the overall length of the blower is very long and the weight It will also be larger and not easy to transport
