Problems solved by technology

Wind generators are effective equipment for wind power generation. Existing wind generators are large in size and high in cost. They can be divided into horizontal axis and vertical axis. The horizontal axis requires a wind-facing device, which has a complex structure and low wind energy conversion efficiency at low wind speeds.
Although the vertical axis does not require a wind-facing device, the wind energy conversion efficiency is low, the stall performance is high, and the cost performance is low. These shortcomings restrict the development of this industry

Abstract

The invention discloses a composite type wind generating set. The composite type wind generating set comprises a base, a generator fixedly arranged on the base, a main shaft connected with the generator and a power generation mechanism arranged on the main shaft. The power generation mechanism comprises a supporting disc arranged on the main shaft, 3-5 supporting rods evenly and horizontally arranged on the supporting disc and blade sets arranged on the supporting rods separately, and the blade sets are clockwise arranged in an end-to-end connection mode. According to the composite type wind generating set, by designing the opening directions of the inner and outer blades in the blade sets, the thickness ratio of the blades, the blade shape, the windward angle and the distance between the inner and outer blades, the utilization efficiency of wind energy is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a composite wind power generating set. Background technique [0002] With the progress of society and the improvement of the quality of life, the requirements for the environment are gradually increasing. Wind power is a clean and renewable energy that is abundant in nature, non-polluting, and environmentally friendly. Wind generators are effective equipment for wind power generation. Existing wind generators are large in size and high in cost. They can be divided into horizontal axis and vertical axis. The horizontal axis requires a wind-facing device, which has a complex structure and low wind energy conversion efficiency at low wind speeds. Although the vertical axis does not require a wind-facing device, the wind energy conversion efficiency is low, the stall performance is high, and the cost performance is low. These shortcomings restrict the development of th...
