Description

本発明は従来の、回転軸両端の回転軸受けが環状レール上を周回する抗力型開閉式発電機において、円環を用いて羽根の中心部を支持することにより、構造的強度を高めるものである。   The present invention increases the structural strength of a conventional drag-type open / close generator in which rotary bearings at both ends of a rotary shaft circulate on an annular rail by supporting the center portion of a blade using an annular ring. .

従来の転軸両端の回転軸受けが環状レール上を周回する抗力型開閉式発電機は、羽根を回転軸の両端の回転軸受けでのみ支える構造だったので、環状レールの直径を大きくすると、羽根全体の強度を高めないとならないものであった。   The conventional drag-type open / close generator in which the rotating bearings at both ends of the rotating shaft circulate on the annular rail has a structure in which the blades are supported only by the rotating bearings at both ends of the rotating shaft. It was necessary to increase the strength.

従来の抗力型発電機には効率の面で実用性が低かったり、強度に問題があるなどの解決すべき課題があった。   Conventional drag generators have problems to be solved such as low practicality in terms of efficiency and problems with strength.

上記目的を達成するために、本発明の抗力型開閉式発電機において請求項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回転軸に設け、羽根同士を連結したものである。また、回転軸の両端に環状レール上を移動可能な回転軸受け設け、その回転軸受けを環状レール上に備えたものである。また、羽根の中央外周部に円環を備え、環状レールの中心部に円環を支持するローラーを備えたものである。   In order to achieve the above object, the drag type open / close generator according to the present invention includes a blade having a function capable of opening and closing a space in a blade frame provided on a rotating shaft and connecting the blades to each other. Is. Further, a rotary bearing that can move on an annular rail is provided at both ends of the rotary shaft, and the rotary bearing is provided on the annular rail. In addition, an annular ring is provided at the center outer peripheral portion of the blade, and a roller for supporting the annular ring is provided at the central portion of the annular rail.

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、特許文献１における抗力型風力発電機において、羽根の中央部に備えられた円環がローラーで支持されることにより、羽根枠の強度を押さえて製造することができる。羽根の部分は特許文献３を利用してもよいので、羽根枠間を連結するのはケーブルでもフレームでもよい。   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 drag-type wind power generator in Patent Document 1, the ring provided at the center of the blade is supported by a roller, thereby manufacturing the blade frame while suppressing the strength of the blade frame. be able to. Patent Document 3 may be used for the blade portion, so that the blade frame may be connected by a cable or a frame.

本発明を実施するための形態を図１〜３に基づいて説明する。環状レール（７）を設け、その上にレールに沿って移動可能な回転軸受け（３）を２つ設ける。２つの回転軸受け（３）は環状レール（７）の中心点を挟んで向かい合うように配置し、そこに回転軸（２）を取り付ける。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）とケーブル（５）によって連結される。羽根枠（４）には開閉幕（１）が備えられ、羽根が水平面より上の垂直に近づいた時に開閉幕（１）を開き羽根枠（４）内の空間を閉じるようにする。これによって、回転軸（２）上側の羽根に風が当たり、回転軸（２）下側の羽根は開閉幕（１）を閉じて面積が大幅に減っているので、上下の羽根の抗力差によって回転する。特許文献１のように羽根の下側に風が当たらないようフェンスなどを設けるとさらに回転力は上がる。   The form for implementing this invention is demonstrated based on FIGS. 1-3. An annular rail (7) is provided, and two rotary bearings (3) movable along the rail are provided thereon. The two rotary bearings (3) are arranged so as to face each other with the center point of the annular rail (7) interposed therebetween, and the rotary shaft (2) is attached thereto. The rotating shaft (2) is provided with eight blade frames (4) every 45 degrees, and is connected by adjacent blade frames (4) and cables (5). The blade frame (4) is provided with an opening / closing curtain (1), and when the blade approaches the vertical above the horizontal plane, the opening / closing curtain (1) is opened to close the space in the blade frame (4). As a result, wind hits the upper blade of the rotating shaft (2), and the lower blade of the rotating shaft (2) closes the opening / closing curtain (1) and the area is greatly reduced. Rotate. When a fence or the like is provided so that wind does not hit the lower side of the blade as in Patent Document 1, the rotational force further increases.

羽根の外周の中心に円環（６）を設け、環状レール（７）の中心部にローラーを備えた支持部（８）を設けることにより、羽根の荷重が円環（６）を通し、支持部（８）で支えられる。これにより、羽根の強度を抑えたまま大型化することができる。また、羽根は抗力を増すために、特許文献３のような構造にするのもよい。図１は斜視図であり、図２は羽根を軸線方向から見た横面図であり、図３は上面図である。   By providing an annular ring (6) at the center of the outer periphery of the blade and providing a support portion (8) with a roller at the center of the annular rail (7), the load of the blade passes through the annular ring (6) and supports it. Supported by part (8). Thereby, it can enlarge, suppressing the intensity | strength of a blade | wing. In addition, the blades may have a structure as described in Patent Document 3 in order to increase drag. 1 is a perspective view, FIG. 2 is a lateral view of the blade viewed from the axial direction, and FIG. 3 is a top view.

実施例１を図４を基に説明する。羽根と回転軸受けを取りのぞいたもので、環状レール（７）の中心部に支持部があることを示している。支持部は球状ローラー（９）とローラー保持器（１０）で構成されている。ローラーは球状なので円環がどの方向をむいても回転することができる。   Example 1 will be described with reference to FIG. The blade and the rotary bearing are removed, and it is shown that there is a support portion at the center of the annular rail (7). The support part is composed of a spherical roller (9) and a roller holder (10). Since the roller is spherical, it can rotate in any direction.

実施例２を図５を基に説明する。球状ローラーを用いた支持部の横面図である。球状ローラー（９）の中心をローラー保持器（１０）の中に入れることにより、球状ローラー（９）が全周囲からの力に回転できるようにしている。   A second embodiment will be described with reference to FIG. It is a side view of the support part using a spherical roller. By putting the center of the spherical roller (9) in the roller holder (10), the spherical roller (9) can be rotated by force from the entire circumference.

実施例３を図６、図７を基に説明する。円筒状ローラー（１１）は中軸（１２）に取り付けられ、中軸（１２）はローラー保持器（１０）に保持されている。なお、中軸（１２）はローラー保持器（１０）に対して自由に回転できる構造であり、ローラー保持器（１０）は地面に固定されている。また、中軸（１２）から牽引ケーブル（１３）が伸ばされ、回転軸受け（３）に連結される。球状ローラーは円環を点でしか保持できないのに対して、円筒状ローラー（１１）は線で円環を保持できるので摩耗がおこりにくい。ただし、円筒状ローラー（１１）は円環の向きと一緒に回転させる必要があるので、中軸（１２）から伸ばされた牽引ケーブル（１３）を回転軸受け（３）に連結することにより、常に円筒状ローラー（１１）と円環の回転方向を一致させる。図６は円筒状ローラー（１１）を用いた支持部であり、図７は羽根を除いた上面図である。   A third embodiment will be described with reference to FIGS. The cylindrical roller (11) is attached to the middle shaft (12), and the middle shaft (12) is held by the roller holder (10). The middle shaft (12) has a structure that can freely rotate with respect to the roller holder (10), and the roller holder (10) is fixed to the ground. Further, the traction cable (13) is extended from the middle shaft (12) and connected to the rotary bearing (3). The spherical roller can hold the ring only with a point, whereas the cylindrical roller (11) can hold the ring with a line, so that it is difficult to wear. However, since the cylindrical roller (11) needs to be rotated together with the direction of the ring, it is always cylindrical by connecting the pulling cable (13) extended from the central shaft (12) to the rotating bearing (3). The rotation direction of the circular roller (11) and the ring is made to coincide. FIG. 6 shows a support using a cylindrical roller (11), and FIG. 7 is a top view excluding the blades.
