Abstract

The invention relates to a wind wheel of a wind driven generator, in particular to a wind driven generator wind wheel provided with straight panel wind wheel blades. The wind driven generator wind wheel aims at solving the problems that an existing propeller type wind wheel blade is low in wind energy absorbing efficiency, fatigable, narrow in the effective utilization range of wind speed and high in manufacturing cost, and wind energy resources are wasted. The wind driven generator wind wheel comprises a tower body, a main shaft (E) and the straight panel wind wheel blades (D), wherein the main shaft (E) is vertically arranged, the tower body comprises a plurality of sets of tower frames (C), one ends of the sets of tower frames (C) are fixed on the main shaft (E), the other ends of the sets of tower frames (C) are distributed in an equiangular horizontal radiating mode relative to the main shaft (E), and each set of tower frame (C) is provided with one straight panel wind wheel blade (D). The blade point speed and the centrifugal force of the wind driven generator wind wheel in the rotating process are both lowered, so that the capacity of absorbing strong wind resources by the wind driven generator wind wheel is greatly enhanced. By means of the telescopic motion of telescopic stopping slices at the two sides, the length of the wind wheel blades is adjusted, and absorption and utilization of gentle wind resources are improved. The wind driven generator wind wheel is used for collecting wind energy.

Description

technical field [0001] The invention relates to a wind wheel of a wind power generator, in particular to a wind wheel of straight wind wheel blades. Background technique [0002] At present, wind power generators usually use propeller-type wind rotors to generate electricity, but the applicant found that the existing propeller-type wind rotors have the following problems: 1. The wind energy absorption rate is low. Because a large amount of wind force escapes directly through the gap between the blades during the operation of the propeller type wind wheel, only part of the wind force acts on the blades, and among the wind forces directly acting on the blades, only part of the wind force decomposes into the power to drive the blades to rotate, so its The absorption efficiency of wind energy is low. 2. The range of effective utilization of wind speed is narrow: the start-up wind speed of the propeller type wind wheel is generally above 3 m / s, so that the breeze resources below...
