Abstract

PURPOSE:To prevent wind turbulence passing a strut by providing a fairing blade rotatably to face a region where rotor blades of the strut go across, in a wind mill in which rotor blades are mounted rotatably around a horizontal axis on an upper part of the strut. CONSTITUTION:A nacelle 3 rotatable around a strut 1 is mounted on the upper end of the strut 1 provided vertically, and a pair of rotor blades 6 are mounted via a rotor hub 5 on an end of a rotary shaft 4 supported by a bearing in a supporting arm 3a extending in the lateral direction of the nacelle 3 to construct a down wind type wind mill. In this wind mill, a fairing blade is rotatably provided on the strut 1 to face an end region L suffering from larger effect of slip stream of wind in a region where rotor blades 6 go across. The fairing blade 9 is constructed by incorporating semi-cut shaped half blades 9a, 9b from right and left and tightening them with a bolt 10 and a nut 11 to form a cross sectional aerofoil or tear drop type.

型風車の場合には、その影響が大きくなる傾向がある。However, a propeller-type wind turbine having such a configuration has a problem in that turbulence generated when the wind passes through the struts affects the rotor blades, resulting in a decrease in the performance of the rotor blades. In particular, in the case of a so-called downwind propeller type wind turbine in which the rotor blades are arranged on the leeward side with respect to the support column, the influence tends to be large.

〔発明の目的〕[Purpose of the invention]

本発明の目的は、支柱を通過する風の乱れによるロータ

置を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a rectifier for a propeller-type wind turbine that reduces performance deterioration of rotor blades due to turbulence in the wind passing through the struts.

付けたことを特徴とするものである。The present invention achieves the above object by providing a rotary shaft extending in the horizontal direction at the upper part of the vertically erected pillars so as to be rotatable around the pillars, and a propeller-type rotor blade is attached to the end of the rotating shaft. The wind turbine is characterized in that a rectifying blade is rotatably attached to a region of the support strut that is traversed by the rotor blade.

以下、本発明を図に示す実施例により説明する。 The present invention will be explained below with reference to embodiments shown in the drawings.

なっている。In the figure, reference numeral 1 denotes a support, and this support 1 is vertically erected by a plurality of tension wires 2. A nacelle 3 is provided at the upper end of the column 1 and is rotatably supported around the column 1. This nacelle 3 has a support arm 3a extending laterally, and a rotary shaft 4 is pivotally supported in the support arm 3a. Two rotor blades 6.6 are added to the end of this rotating shaft 4 via a rotor hub 5. The number of rotor blades 6 is not limited to two, and may be one, or may be three or more. The rotor blade 6 is attached to the rotor hub 5 via a rotatable support shaft 7, and its attachment angle is automatically changed according to wind force.

うになっている。The rotor blade 6 is a downwind type wind turbine that moves to the leeward side while rotating the nacelle 3 around the support column in response to the wind in the direction of the arrow W, and rotates the rotating shaft 4 by its own rotation. The rotation of the rotating shaft 4 rotated by the rotor blade 6 drives a generator (not shown) in the yoke case 8 via a bevel gear (not shown).

整流羽根９は、第３．４図に示すように、半割形状の片
羽根９ａ。Further, the support column 1 is rotatably provided with rectifying vanes 9 corresponding to the end region, which is particularly affected by the wake of the wind, within the region crossed by the rotor blades 6°6. This rectifying blade 9 is a half-shaped single blade 9a, as shown in FIG. 3.4.

ある。The cross-sectional shape of the rectifying blade 9 is an airfoil shape or a teardrop shape that is a combination of a semicircle and a triangle, and has a shape that reduces the coefficient of resistance to wind flow. Further, the shape in side view is a trapezoidal shape so that it does not interfere with the tension wire 2 when rotating 360 degrees around the support 1.

にある。The rectifying blade 9 assembled as described above is rotatably supported via a thrust bearing 12 attached to the support column 1.
With respect to the wind direction of arrow W, it rotates so that its longitudinal direction faces downwind, guiding the wind to its left and right sides and causing it to flow backward. Therefore, the turbulence in the wake of the wind passing through the rectifying blade 9 is rectified, and wind energy is transmitted to the rotor blade 6 without the occurrence of Karman vortices or the like that would occur when only the support column 1 is placed. In other words, the rectifying blades 9 minimize the rate of deceleration of the flow velocity caused by the struts 1, thereby imparting wind energy to the rotor blades 6.

このため、ロータブレード６の性能を向上することがで
きる。Therefore, the performance of the rotor blade 6 can be improved.

また、支柱１に対する風の抵抗を軽減するため、支柱構
造の軽量化にも寄与することができる。Furthermore, since the wind resistance to the strut 1 is reduced, it is possible to contribute to the weight reduction of the strut structure.

This is most effective in the case of a so-called downwind type propeller type wind turbine in which the rotor blade 6 is attached to the leeward end of the rotating shaft 4, but in the case of a so-called amplifier wind type wind turbine in which the rotor blade 6 is attached to the windward end Even in such cases, the influence of turbulence of the wind passing through the support column 1 is exerted, so that the rectifying device of the present invention can be applied.

In the wind turbine, the rectifying blades are rotatably attached to correspond to the areas of the struts crossed by the rotor blades, so the rectifying blades eliminate Karman vortices, etc. that occur when wind passes through the struts, and reduce the flow velocity. deceleration rate can be minimized. Therefore, the performance of the rotor blade can be improved.
