Vertical-axis super-large wind turbine generator system structure with double struts and water-floating boats

Abstract

The invention relates to a vertical-axis super-large wind turbine generator system structure with double struts and water-floating boats, belonging to the technical field of super-large wind power generation. According to the technical scheme, the vertical-axis super-large wind turbine generator system structure with double struts and water-floating boats comprises a vertical-axis windmill, water-floating annular boats (5), an annular water groove (6) and wind turbines (9), wherein a plurality of the water-floating annular boats are connected by bottomless-boat type connection plates to form a water-floating annular boat, a vertical blade and the single water-floating annular boat are arranged in pairs, and the water-floating annular boat runs in the middle of the annular water groove; and the rotation of the blade of the vertical-axis windmill is supported by the water-floating annular boat. An upper flange and a lower flange of the centre shaft of the vertical-axis windmill are axially connected with the struts on the blade so as to ensure the verticality of the centre shaft during the running of the windmill; and the lifting-force windmill and the water-floating annular boat in the scheme have an upward-lifting force during the rapid rotation of the windmill, thus reducing the resistance of the boat in water; and the centre shaft of the vertical-axis windmill is connected with the wind turbines, and thus the vertical-axis wind turbines can be produced into the a megawatt-scale super-large wind turbine generator system.

Description

technical field [0001] The invention relates to a super-large wind power generation unit structure of a vertical-axis double-rod water pontoon type, and belongs to the technical field of super-large wind power generation. Background technique [0002] At present, vertical axis blades are mostly used in vertical axis wind turbines, forming the vertical axis windmill technology. Due to the technical limitations of the central axis and support force of the vertical axis windmill, it is difficult to make megawatt-level extra large vertical axis blades. Wind turbines, especially windmills with vertical axis windmills with a rotation diameter of more than 50 meters, are difficult to manufacture, and extra-large wind turbines cannot be manufactured. However, the existing water floating large vertical blades are not equipped with a central rod and a blade connecting rod as a support, and the weight of the blades is large, and the water resistance is large. The blades of ten meters o...

Problems solved by technology

[0002] At present, vertical axis blades are mostly used in vertical axis wind turbines, forming the vertical axis windmill technology. Due to the technical limitations of the central axis and support force of the vertical axis windmill, it is difficult to make megawatt-level super large vertical axis blades. Wind turbines, especially windmills with vertical axis windmills with a rotation diameter of more than 50 meters, are difficult to manufacture, and extra-large wind turbines cannot be manufactured

However, the existing water floating large vertical blades are not equipped with a central rod and a blade connecting rod as a support, and the weight of the blade is large, and the water resistance is large. The blades of ten meters or tens of meters are directly installed on the water wheel in the tank. The supporting force is difficult to meet the process requirements, and the independent blades with large height are easily blown down by the wind without support, especially when the water floating windmill rotates, the shaking generated has a negative impact on the operation of the wind motor, and Problems such as low utilization rate of wind energy
