Embodiment Construction

[0034] figure 1 It is a schematic diagram showing the blade set 10 of the improved vertical wind power generator of the present invention, the blade set 10 is supported on a vertical shaft 101 that drives a generator (not shown in the figure) to rotate, and the blade set 10 includes a A rotating frame 102, and a plurality of vertical blades 103 arranged on the rotating frame 102. Each of the blades 103 has a vertical rotating shaft 104 and is pivotably disposed on the rotating bracket 102 . Such as figure 2 As shown, each blade 103 is additionally provided with an adjustable connecting rod 105, which can be connected to the rotating bracket 102, so that each blade 103 can be rotated and adjusted around its vertical rotation axis 104, so as to maintain the distance between each blade 103 and the windward surface. The best angle of attack (Pitch Angle).

[0035] The so-called angle of attack of the blade to the airflow is defined as the angle between the front and rear edges...

Abstract

The invention relates to an improved vertical vane assembly of a wind aerogenerator and the vane assembly is supported on a vertical axle that drives a generator to rotate and comprises a rotating bracket and a plurality of vertical vanes uniformly arranged on the rotating bracket at intervals, the vanes respectively have a vertical rotating axle which is arranged on the rotating bracket in a pivoted manner, each vane is additionally provided with an adjustable connecting rod that is connected to the rotating bracket to lead each vane to rotate around the vertical rotating axle and maintain the optimum angle of attack between each vane and a windward side. In addition, the invention provides a variable winding method of a two-step and three-step wind aerogenerator which has a rotating speed and a generated voltage when operating, a comparator is utilized for comparing the rotating speed and the generated voltage of the wind aerogenerator with a preset value of the comparator; and under different rotating speed, coils are respectively connected in series or in parallel to lead the electricity generated by the generator to be in a limited range, thus avoiding causing unexpected misfortune.

Description

technical field [0001] The invention relates to an improvement of a blade set of a vertical wind power generator and a variable winding method of the wind power generator. Background technique [0002] Generally speaking, the blades of wind power generators are generally divided into two types: horizontal axis wind blades (HAWT) and vertical axis wind blades (VAWT), both of which can effectively convert wind energy into kinetic energy of the wind blades. Because horizontal axis wind blades have been used in Europe as early as the 15th century, they have a relatively large market share. Since the advancement of aerodynamics in the late 1960s, the technology for constructing wind blades has also improved significantly. Today's horizontal axis wind blade technology has reached a power output scale of 5MW and a conversion efficiency of 40% from wind power to electricity. [0003] However, wind power generation has the following problems. In other words, if wind power generati...
