Description

本発明は、流水を利用した自然エネルギーの利用において、水車ブレードの取付方法に関する。   The present invention relates to a method for attaching a turbine blade in the use of natural energy using flowing water.

最近、地球温暖化により自然環境の保全と化石燃料の代替として、水力発電においても、従来の河川にダム建設や取水口の設置工事などの自然環境に影響を与えるものではなく、新たな方法が求められている。
また、落差のきわめて少ないゆるやかな流水による発電においても、ブレードを流水に対し直角に設置するため、スムーズに安定して回転させるには、ブレードの枚数を多くする必要があり、コストアップとごみ、木片や草等の浮遊物の付着による水車の故障、周辺への水しぶきや水はねあげなどの原因になっていた。 Recently, as a substitute for fossil fuel and the preservation of the natural environment due to global warming, hydroelectric power generation also does not affect the natural environment such as dam construction and water intake installation work on conventional rivers. It has been demanded.
In addition, even in power generation with gentle running water with very little drop, the blades are installed at right angles to the running water, so it is necessary to increase the number of blades in order to rotate smoothly and stably, increasing costs and waste, It caused water turbines to break down due to the attachment of floating objects such as wood chips and grass, and water splashing and water splashing to the surrounding area.

本発明は、自然環境への影響を最小限にし、落差のきわめて少ない流水の運動エネルギーを利用し、従来のブレードを直角に設置した水車よりも、ブレードの枚数を軽減でき、また回転ムラや脈動を抑え、スムーズに効率よく回転（発電）することが出来ることを特徴とするマイクロ水力発電用の水車ブレードを提供する。   The present invention minimizes the impact on the natural environment, uses the kinetic energy of running water with extremely low head, and can reduce the number of blades compared to conventional turbines with blades installed at a right angle, and can also cause uneven rotation and pulsation. A turbine blade for micro hydroelectric power generation is provided, which is capable of smoothly and efficiently rotating (power generation).

本発明においては、ゆるやかな流水に対し、回転方向に対する脈動を減らし、安定した回転を持つ水車ブレードを製作出来る。   In the present invention, it is possible to manufacture a turbine blade having a stable rotation by reducing pulsation in the rotation direction with respect to gentle flowing water.

本発明は、以上のとおりのものであるから、回転ムラや脈動を抑え、ブレードの枚数が少なくても、スムーズに効率よく回転（発電）するマイクロ水力発電用の水車ブレードが提供でき、自然環境への影響も最小限にすることができ、今まで利用されていなかった放水路、農業用水等の水力エネルギーを利用することができる。
また、本発明の水車ブレードを使用した水力発電システムを並列もしくは、直列に複数併設した場合、流水を堰き止めることなく、発電に必要とする流水を得ることができ、大きな電力を得ることができる。 Since the present invention is as described above, it is possible to provide a turbine blade for micro hydroelectric power generation that suppresses rotation unevenness and pulsation, and can smoothly and efficiently rotate (power generation) even when the number of blades is small. The impact on the water can be minimized, and hydraulic energy such as water discharge channels and agricultural water that have not been used can be used.
Further, when a plurality of hydroelectric power generation systems using the turbine blades of the present invention are provided in parallel or in series, it is possible to obtain running water necessary for power generation without damming running water and obtain large electric power. .

An embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the rotating main shaft 4 connected to the generator via a direct connection or a speed increaser,
On the rotating plate 5 fixed with the rotating plate fixture 7 and rotating together with the rotating spindle 4,
There are mounting holes for the post mounting fixtures 6 that are equally divided according to the number of mountings.
A blade column 3 is attached to the rotating plate 5 by a column attachment 6.
The blade 1 is fixed by the blade mounting / deflection angle adjuster 2 that creates the blade deflection angle θ.
Then, as shown in FIG. 2, the blade 1 perpendicular to the flowing water is adjusted with the blade mounting / deflection angle adjusting tool 2, and each blade 1 constituting the water turbine is pivoted on the blade column 3 from the position perpendicular to the flowing water. age,
A blade 1 having a blade deflection angle θ deflected in the range of 10 degrees to 35 degrees counterclockwise or clockwise.
The blades are alternately paired with a counterclockwise rotation and a clockwise rotation before and after each blade (form a “C”).
As a result, the water turbine can be smoothly rotated with a small number of blades without stopping running water with a very low head.
In addition, by changing the shape of the blade 1 so that it can receive flowing water on both sides, the blade 1 can also be used as a turbine blade using wave power at sea.
