Description

本発明は抗力型開閉式発電機の羽根に関する物である。     The present invention relates to a blade of a drag type switching generator.

従来の開閉式抗力型発電機の羽根は、平面的な羽根を開閉する構造であったので抗力係数が低く、抗力差による回転力の低いものであった。   The blades of the conventional open / close type drag generator have a structure in which the flat blades are opened and closed, so the drag coefficient is low and the rotational force due to the drag difference is low.

本発明は、従来の開閉式の抗力型発電機の羽根に抗力係数を高める仕組みを用いることで、回転力の高い抗力型開閉式発電機で用いる羽根を提供するものである。上記の特許文献１〜４は羽根枠内の空間を開閉することにより、回転軸の左右で抗力差を作り回転する仕組みであるが、問題は羽根の構造が平面的であるため羽根枠内の空間を閉じたとしても抗力係数が低いことである。ただし特許文献５に関しては羽根枠内の空間を開閉する仕組みであるが、回転軸の軸線を流体の流れと平行に設置するプロペラ型の発電機であり、本発明の抗力型とは回転動作が異なるものであり、当発明を用いても回転力上昇になんら寄与しない。   The present invention provides a blade used in a drag-type open / close generator with high rotational force by using a mechanism for increasing the drag coefficient in the blade of a conventional open / close-type drag generator. The above Patent Documents 1 to 4 are mechanisms that rotate by creating a drag difference on the left and right of the rotation axis by opening and closing the space in the blade frame, but the problem is that the structure of the blade is planar, so Even if the space is closed, the drag coefficient is low. However, Patent Document 5 is a mechanism for opening and closing the space in the blade frame, but it is a propeller type generator in which the axis of the rotating shaft is installed in parallel with the flow of the fluid, and the drag type of the present invention does not rotate. It is different, and even if this invention is used, it does not contribute at all to a rotational force raise.

上記目的を達成するために、抗力型開閉式発電機の羽根の構造において請求項１に係るものは、羽根枠内の空間を開閉できる機能を備えた羽根を３つ以上回転軸に設け、回転軸の軸線を中心とした円周方向の隣り合う羽根同士を連結し、そのようにしてできた空間において、回転軸の軸線と平行方向の空間に、羽根間を開閉できる機能を設け、回転軸の軸線と直交方向の空間を幕で塞いだものである。 In order to achieve the above object, in the structure of the blades of the drag-type opening / closing generator, the one according to claim 1 is provided with three or more blades provided with a function capable of opening and closing the space in the blade frame on the rotating shaft. The adjacent blades in the circumferential direction centering on the axis of the shaft are connected to each other, and in the space thus formed, a function is provided in the space parallel to the axis of the rotating shaft so that the blade can be opened and closed. The space perpendicular to the axis is closed with a curtain .

本発明は、以上説明したように構成されており、以下に記載されるような効果を有する。 請求項１に係る仕組みを用いた場合、流体の流れの中で、回転軸を挟んで片側の羽根は羽根枠内の空間を開き反対側の羽根枠内の空間を閉じることにより、抗力差を発生させて回転軸を回転させる部分は従来の抗力型開閉式発電機と同じである。だが、当発明は隣り合う羽根をフレームやケーブルなどで連結し、それにより作られる回転軸の軸線と平行方向の羽根枠間の空間も開閉できるようにし、さらに、回転軸と直交する羽根枠間を幕で塞いだものである。 The present invention is configured as described above and has the effects described below. When the mechanism according to claim 1 is used, in the flow of the fluid, the blade on one side across the rotation shaft opens the space in the blade frame and closes the space in the blade frame on the opposite side, thereby reducing the drag difference. The part that generates and rotates the rotating shaft is the same as that of the conventional drag type open / close generator. However, the invention should concatenates adjacent Ri fit blade such a frame or a cable, whereby also the space between the axes parallel to the direction of the blade frame of the rotating shaft made to be able to open and close, further, the blade frame perpendicular to the rotational axis The space is closed with a curtain.

羽根枠内の空間の開閉と共に、回転軸の軸線と平行方向の羽根枠間の空間も同じように回転軸を挟んで、流れを受けたい側で空間を閉じ、受け流したい側で空間を開く。これにより、羽根が平面ではなく立体的に囲われた形となり、抗力係数が格段に向上し回転力が上がる。回転軸の軸線と平行方向の羽根枠間は羽根の外周側にだけではなく、また、羽根を巨大化に応じて、羽根枠の中間部分も連結して開閉できるようにすれば強度の補強にもなる。羽根枠内や羽根枠間の空間を開閉するには幕状のものや、板のような片を複数用いたりするとよい。   Along with the opening and closing of the space in the blade frame, the space between the blade frames in the direction parallel to the axis of the rotation shaft is similarly sandwiched between the rotation shafts, the space is closed on the side where the flow is desired and the space is opened on the side where the flow is desired. As a result, the blades are three-dimensionally enclosed rather than flat, the drag coefficient is significantly improved, and the rotational force is increased. The space between the blade frames in the direction parallel to the axis of the rotating shaft is not only on the outer peripheral side of the blades, but if the blades are enlarged, the middle part of the blade frames can be connected to open and close to reinforce the strength. Also become. In order to open and close the space within the blade frame or between the blade frames, a plurality of pieces such as curtains or plates may be used.

本発明を実施するための形態を図１に基づいて説明する。回転軸（２）には８つの羽根枠（４）が４５度おきに備えられ、それぞれ隣り合う羽根枠（４）は羽根枠連結フレーム（６）によって連結される。羽根枠（４）にはレール（５）設けられ、レール（５）には開閉幕（１）が備えられている。また羽根枠連結フレーム（６）には羽根枠間レール（８）が備えられ、羽根枠間レール（８）には羽根枠間開閉幕（７）が備えられている。また回転軸（２）と直交方向の羽根枠（４）同士の間には、幕（３）を張る。開閉幕（１）と羽根枠間開閉幕（７）は動力により自在に開閉させることができる。また、開閉させる仕組みは幕を用いた以外のものでもよい。例えば特許文献４にあるような開閉片を用いてもよい。   An embodiment for carrying out the present invention will be described with reference to FIG. The rotating shaft (2) is provided with eight blade frames (4) every 45 degrees, and the adjacent blade frames (4) are connected by the blade frame connecting frame (6). The blade frame (4) is provided with a rail (5), and the rail (5) is provided with an opening / closing curtain (1). The blade frame connecting frame (6) is provided with an inter-blade frame rail (8), and the inter-blade frame rail (8) is provided with an inter-blade frame opening / closing curtain (7). Further, a curtain (3) is stretched between the rotating shaft (2) and the blade frames (4) in the orthogonal direction. The opening / closing curtain (1) and the opening / closing curtain (7) between the blade frames can be freely opened and closed by power. Further, the mechanism for opening and closing may be other than using a curtain. For example, an opening / closing piece as disclosed in Patent Document 4 may be used.

実施例１を図２を基に説明する。図２は図１の内部構造で、図１より幕（３）と羽根枠連結フレーム（６）および羽根枠間開閉幕（７）を省いたものである。レール（５）に備えられた開閉幕（１）は回転軸（２）の方向へ巻き取られる。これは中心側に配置することで抵抗を低下させるためである。   Example 1 will be described with reference to FIG. FIG. 2 shows the internal structure of FIG. 1, in which the curtain (3), the blade frame connecting frame (6), and the inter-blade frame opening / closing curtain (7) are omitted from FIG. The opening / closing curtain (1) provided on the rail (5) is wound up in the direction of the rotating shaft (2). This is because the resistance is lowered by disposing it on the center side.

実施例２を図３を基に説明する。回転軸（２）の軸線方向から見た図である。回転軸（２）には８つの羽根枠（４）が４５度おきに備えられ、それぞれ隣り合う羽根枠（４）は羽根枠連結フレーム（６）によって連結される。回転軸（２）の軸線と直交する方向の羽根枠（４）間には幕（３）が張られる。図１と違い、羽根枠（４）の外周部だけでなく中間部も羽根枠連結フレーム（６）によって連結されている。羽根枠（４）の枚数や羽根枠連結フレーム（６）の連結箇所の数は、羽根の直径の大きさに応じて最適なものを選択するとよい。   A second embodiment will be described with reference to FIG. It is the figure seen from the axial direction of the rotating shaft (2). The rotating shaft (2) is provided with eight blade frames (4) every 45 degrees, and the adjacent blade frames (4) are connected by the blade frame connecting frame (6). A curtain (3) is stretched between the blade frames (4) in the direction perpendicular to the axis of the rotation shaft (2). Unlike FIG. 1, not only the outer peripheral part of the blade frame (4) but also the intermediate part is connected by the blade frame connection frame (6). The optimum number of blade frames (4) and the number of connecting portions of the blade frame connecting frame (6) may be selected according to the size of the diameter of the blade.

実施例３を図４および図５を基に説明する。L型レール（１２）を用いることで、羽根枠（４）の開閉幕（１）で羽根枠連結フレーム（６）内の空間の開閉を行えるようにしたものである。開閉幕（１）は幕の巻軸（９）に巻かれ、羽根枠（４）と羽根枠連結フレーム（６）に取り付けられたL型レール（１２）に沿って移動が可能である。開閉幕（１）の先端に開閉ケーブルA（１３）を連結し、開閉ケーブルA（１３）は滑車（１０）を経由してケーブルの巻軸（１１）で巻き取られる。このようにしてケーブルの巻軸（１１）を巻けば、開閉幕（１）のみで羽根枠（４）と羽根枠連結フレーム（６）内の空間を閉じることができ、幕の巻軸（９）を巻けば、羽根枠（４）と羽根枠連結フレーム（６）内の空間を開くことができる。図４は開閉幕（１）と開閉ケーブルA（１３）と幕（３）を省いたもので、内側の正面図である。また、図５の斜視図において開閉ケーブルA（１３）が枠の中央付近で張られているのは仕組みを分かりやすくするためであり、出来れば抵抗にならないようにL型レール（１２）の中を伝わせた方が良い。   A third embodiment will be described with reference to FIGS. 4 and 5. By using the L-shaped rail (12), the opening and closing curtain (1) of the blade frame (4) can be used to open and close the space in the blade frame connection frame (6). The opening / closing curtain (1) is wound around a winding shaft (9) of the curtain and is movable along an L-shaped rail (12) attached to the blade frame (4) and the blade frame connecting frame (6). An opening / closing cable A (13) is connected to the tip of the opening / closing curtain (1), and the opening / closing cable A (13) is wound around the winding shaft (11) of the cable via the pulley (10). If the winding shaft (11) of the cable is wound in this manner, the space in the blade frame (4) and the blade frame connecting frame (6) can be closed only by the opening and closing curtain (1), and the curtain winding shaft (9 ) Can open the space in the blade frame (4) and the blade frame connecting frame (6). FIG. 4 is a front view of the inside, with the opening / closing curtain (1), the opening / closing cable A (13) and the curtain (3) omitted. Also, in the perspective view of FIG. 5, the opening / closing cable A (13) is stretched near the center of the frame for easy understanding of the mechanism, and if possible, the L-shaped rail (12) It is better to let

実施例４を図６を基に説明する。羽根枠（４）の連結に羽根枠連結ケーブル（１５）を用いたもので、フレームでなくても羽根枠間の空間の開閉をさせる仕組みを作ることが可能であることを示した図である。蛇腹状開閉幕（１４）の左右に取り付けられたケーブル移動用金具（１７）の穴に羽根枠連結ケーブル（１５）を通し、蛇腹状開閉幕（１４）の上端をケーブル固定用金具（１８）で開閉ケーブルB（１６）に固定し、蛇腹状開閉幕（１４）の下端を羽根枠に固定する。この状態で開閉ケーブルB（１６）を上下に移動させれば、蛇腹状開閉幕（１４）も上下に移動する。図１のように羽根枠連結フレーム（６）を使うよりも簡単な構造で重量も軽い。   A fourth embodiment will be described with reference to FIG. It is the figure which used the blade frame connection cable (15) for connection of a blade frame (4), and was a figure which showed that it was possible to make the mechanism which opens and closes the space between blade frames even if it is not a frame. . The vane frame connecting cable (15) is passed through the holes of the cable moving bracket (17) attached to the left and right of the bellows-like opening / closing curtain (14), and the upper end of the bellows-like opening / closing curtain (14) is attached to the cable fixing fitting (18) To the opening / closing cable B (16) and the lower end of the bellows-like opening / closing curtain (14) to the blade frame. When the opening / closing cable B (16) is moved up and down in this state, the bellows-shaped opening / closing curtain (14) also moves up and down. As shown in FIG. 1, the structure is simpler and lighter than using the blade frame connecting frame (6).
