Abstract

PROBLEM TO BE SOLVED: To solve problems in actually using a high power generating device by a wind mill having drag-type blades wherein the drag-type wind mill is usually longitudinally installed, and a rotating radius of the blades is small, which is not suitable for high output. SOLUTION: In this drag-type collecting wind mill, a collecting wind mill 3 forgetting the total output of all of blade units, and formed by stacking and fixing the blade units 2 by horizontally connecting plural drag-type blades on the same plane, and connecting the adjacent blade units 2 by a chain 4, is installed on a position out of a center of a turntable 7 mounted on an upper part of a tower 8, and orthogonal to a center line symmetrically left and right. A pulley or a gear fixed to a center of a totalizing output shaft 5 of the collecting wind mill 3 and a pulley or a gear fixed to an uppermost part of an upright transfer shaft connected to the power generator at a lower part of the tower are connected by a belt or a chain 4.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for converting a drag type wind turbine into a high output wind turbine.

[0002]

2. Description of the Related Art Practical application of a high-power generator using a windmill having a drag-type blade has not been advanced. The drag type wind turbine is usually installed vertically, and is not suitable for high output because the turning radius of the blade is small. The present invention is based on Japanese Patent Application No. 2000-241.

SUMMARY OF THE INVENTION The present invention is based on Japanese Patent Application No. 2000-241890 [Windmill for Roof Installation] and a patent application dated December 15, 2000 [reference number] 12.
A related application relating to 17 [Windmill] relates to a technology for making a drag-type windmill a practical high-output windmill.

[Means for Solving the Problems] Japanese Patent Application No. 2000-2418
The wind turbine 90 [roof installation wind turbine] is characterized by a power generating unit having a drag type blade horizontally connected symmetrically horizontally and integrated into a frame. [Reference number] 1
217 [Windmill] is a stack in which the blade units 2 of drag type blades 1 are horizontally connected and integrated into a frame, and are stacked in the same plane, and adjacent blade units are connected by a chain 4 or the like. This is a technique for obtaining a total output, in which a collective wind turbine in which the blade units 2 are stacked is installed on a turntable 7 above the tower 8, and the total output of the blade units 2 is transmitted to a power generator 9 below the tower. As a means, a bevel gear is fixed to the total output shaft 5, a transmission shaft 10 connected to the generator is installed so as to penetrate through the rotation center of the turntable 7, and the bevel gear is fixed above the bevel gear, and both bevel gears are fixed. Was engaged. This method has the disadvantage that the bevel gear of the total output shaft is slightly displaced from the center of the shaft, so that as the load on the bevel gear of the transmission shaft increases, torque is applied to the turntable and the windmill deviates from the wind direction. are doing. Therefore, the present invention proposes the following method to eliminate this disadvantage. The collective wind turbine 3 is installed symmetrically at a position off the center of the turntable above the tower and orthogonal to the center line. A pulley A6 or a gear fixed to the center of the integrated output shaft 5 of the collective wind turbine 3 and a pulley B11 or a gear fixed to the top of an upright transmission shaft 10 connected to a generator below the tower 8 are connected to a belt 13 or a chain. Connect with.

[0005]

The pulley A6 of the total output shaft 5 is arranged vertically, the pulley B11 of the transmission shaft 10 is arranged horizontally, and both pulleys are connected by twisting the belt 13 by 90 degrees. Since the pulley A of the output shaft is mounted at the center of the shaft, the torque of the output shaft does not apply torque to the turntable, and the windmill follows the attitude around the center axis of the turntable 7 without resistance according to the wind direction. Can be done. Since the gathering windmill 3 is not located on the center of the turntable 7, the attitude of the turntable is caused to always follow the wind of the windmill by the wind received by the gathering windmill. In other words, it has the function of the tail. Therefore, according to the present invention, the tail fin can be omitted, and the power generator 9 can be installed on the ground, so that a slip ring is not required, the maintenance is very easy, and the cost can be greatly reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. [FIG. 1] is a front view of a windmill, and [FIG. 2] is a plan view taken along the line II. At the upper part of the tower 8, the collective wind turbine 3 is installed symmetrically at a position off the center of the turntable at the upper part of the tower and orthogonal to the center line. A pulley A6 or a gear fixed to the center of the integrated output shaft 5 of the collective wind turbine 3 and a pulley B11 or a gear fixed to the uppermost part of a transmission shaft 10 connected to a generator below the tower and fixed upright, to a belt 13 or a chain. Connect with. Pulley A6 and pulley B10 are orthogonal,
The belt 13 connects the two in a 90-degree twisted form and transmits the rotation of the integrated output shaft 5 to the transmission shaft 10. The collective windmill 3 that has received the wind rotates downwind of the turntable around the center of the turntable, and follows the attitude so as to always receive the wind toward the front of the windmill. Note that, although complicated, a transmission method using a combination of gears is also possible. FIG. 3 is a side view of the wind turbine. In the drag type blade 1, half of the wind receiving surface rotates against the wind, so that there is no choice but to lose output energy. Therefore, measures such as shielding the surface are often taken. In the collective wind turbine of the present invention, the horizontally arranged blade units 2 are vertically adjacent to each other. Therefore, a wind collecting plate 14 that covers the wind receiving rear side of the drag type blade and collects the wind on the wind receiving side of the adjacent drag type blade is installed in the blade unit 2. As a result, it is possible to shield the wind that hits the part that rotates against the wind, and at the same time, guide the wind to the wind receiving surface of the adjacent blade, thereby greatly improving the output.

[0007]

The present invention has the following features. 1. The tail can be omitted. 2. Slip ring is unnecessary. 3. Significant energy improvement can be expected by the wind collecting plate.
