Wheel type variable attack angle lift windmill

Abstract

The invention relates to a wheel type variable attack angle lift windmill, which belongs to the technical field of wind power generation and comprises a base steel tower, a hammer type T-shaped platform capable of rotating in the horizontal direction is mounted on the steel tower, and a main transmission shaft is horizontally mounted in the center of the interior of a hammer head part of the T-shaped platform; two wheel type windmill assemblies connected with the main transmission shaft are mounted at the two ends of the hammer head part; the windmill assembly is provided with a wheel type supporting frame, a side transmission shaft arranged at the axis position of the supporting frame is connected with the main transmission shaft, a plurality of sets of lifting force fan blades capable of swinging are installed on the outer edge of the wheel type supporting frame, and the lifting force fan blades are connected with near-circle variable attack angle track mechanisms installed at the two ends of the T-shaped platform hammer head through swing arm transmission mechanisms. According to the wheel type variable-attack-angle lift windmill, the windmill assembly of a wheel type structure is adopted, and the overall structure is more compact; meanwhile, the windmill assembly is matched with the rotatable T-shaped platform so that the windmill assembly can be automatically aligned with the wind direction, and self-starting is easily achieved.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a horizontal-axis lift windmill whose blade attack angle can be actively adjusted. Background technique [0002] According to the different rotation axes, wind turbines are mainly divided into horizontal axis wind turbines and vertical axis wind turbines. The vertical axis is restricted by the structure itself. At present, it is mainly used in small and medium wind power generation equipment. For wind power generation equipment, horizontal axis wind turbines still occupy the mainstream position. The drive of the horizontal axis wind turbine mainly relies on the rotor blades, and the main driving parts are concentrated on the tip of the blades. In order to capture greater wind power, the measured length of each rotor blade on a 600-kilowatt wind turbine is about 20 meters. The blades of megawatt-class wind turbines are even as long as 100 meters, and there are high requirements f...
