Abstract
[Problem] To address problems related to vertical axis-type power generation, such as "wind acting in a turning direction and wind of the same strength which serves as a brake act simultaneously on blades which rotate on a vertical axis, resulting in poor efficiency," "installation locations are restricted owing to noise and the risk posed by exposed rotating blades," "performance deteriorates as a result of bearings being exposed to wind and rain," and "suspended matter and fluid come into contact with the rotating blades, and cause breakdowns and the like." [Solution] A cover having a shape like that indicated in the drawings is attached. As a result of the shape, wind received by the front surface is guided into the cover such that the wind hits the blades in the rotation direction, and negative pressure generated by the wind which has an increased flow rate and flows from side surfaces of the cover towards a rear end portion, is used at the same time as force is exerted in a direction that pushes the blades, to generate a swirling vortex having the axis of the rotating blades at the centre, and achieve conversion into force which rotates the rotating blades from all directions. Accordingly, noise reduction is achieved while simultaneously inhibiting direct exposure of rotary bearings to wind and rain, by covering the rotating blades.

この発明は、流体発電用のファンのカバーの形状に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the shape of a fan cover for fluid power generation.
この発明は、流体発電用のファンのカバーの形状に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the shape of a fan cover for fluid power generation.
従来の風力発電装置として使用されているものに、水平軸型（プロペラ式、セイルウィング式、オランダ式、多翼式など）、垂直軸型（ダリウス式、直線翼式、サボニウス式、パドル式、クロスフロー式、S字ローター式など）がある。
What is used as a conventional wind power generator is a horizontal axis type (propeller type, sail wing type, Dutch type, multi-wing type, etc.), vertical axis type (Darius type, straight wing type, Savonius type, paddle type, Cross-flow type, S-shaped rotor type, etc.).
水平軸型の場合、発電効率が良い反面、専有面積が大きいため、複数設置する場合、各機器間の間を空けなければならず、結果的に効率を上げるためには、広大な面積が必要となる。
垂直軸型の場合、設置面積の面でメリットがあるものの、垂直軸上で回転する羽根に対して、回す方向に働く風と、同じ強さでブレーキとなる風が同時に作用するため、発電効率が悪く、様々な形状によってその問題を解決しようと開発がすすめられている。
また双方とも回転羽根がむき出しとなっているため、安全面と騒音の二つの問題があるため、設置場所の制限や、安全確保のための専有面積の確保が必要となっている。
合わせて構造上、回転軸受部分が風雨にさらされるケースが多く、それによりメンテナンスの頻度も高くなるという問題も抱えている。
そこで、本発明によって垂直軸型の効率を上げると同時に、安全装置として回転羽根を覆うことにより、防音対策と軸受の保護を同時に行い、より設置場所の自由度を上げ、小型化したものを多数設置することを可能にすることによる、発電効率の高効率化を図ることを課題とする。
小型水力発電の場合、水平軸型の場合、発電機を水中に沈めるか、水上に発電機を設置するには、傘歯車等により回転方向を変換しなければならず、構造的に複雑な上、効率の低下と製造コストの上昇が発生する。
また一機当たりの発電効率を上げるためには、羽根の面積を大きくする必要があり、それにより水平方向に専有面積が大きくなるので、木やゴミ等の浮遊物と接触する確率が高くなり、構造上回転羽根にそれらの浮遊物が直接接触することもあり、障害の発生率も高くなる。 In the case of the horizontal axis type, the power generation efficiency is good, but since the exclusive area is large, when installing multiple units, it is necessary to leave a space between each device. As a result, a large area is required to increase the efficiency. It becomes.
In the case of the vertical axis type, although there is an advantage in terms of installation area, the wind that acts in the direction of rotation and the wind that acts as a brake act simultaneously on the blades rotating on the vertical axis, so the power generation efficiency However, development is being promoted to solve the problem with various shapes.
Moreover, since both of the rotating blades are exposed, there are two problems of safety and noise. Therefore, it is necessary to limit the installation location and secure a dedicated area for ensuring safety.
In addition, there are many cases in which the rotary bearing part is exposed to wind and rain due to the structure, which also increases the frequency of maintenance.
Therefore, the present invention increases the efficiency of the vertical axis type and at the same time covers the rotating blades as a safety device, thereby simultaneously performing soundproofing measures and protecting the bearings, increasing the degree of freedom of installation location, and reducing the size It is an object to improve the power generation efficiency by making it possible to install.
In the case of small hydropower generation and horizontal axis type, in order to submerge the generator in the water or to install the generator on the water, the direction of rotation must be changed with a bevel gear, etc. As a result, the efficiency decreases and the manufacturing cost increases.
Also, in order to increase the power generation efficiency per machine, it is necessary to increase the area of the blades, thereby increasing the exclusive area in the horizontal direction, increasing the probability of contact with floating objects such as wood and garbage, Due to the structure, these floating objects may come into direct contact with the rotating blades, resulting in an increased failure rate.
垂直軸型の場合、設置面積の面でメリットがあるものの、垂直軸上で回転する羽根に対して、回す方向に働く風と、同じ強さでブレーキとなる風が同時に作用するため、発電効率が悪く、様々な形状によってその問題を解決しようと開発がすすめられている。
また双方とも回転羽根がむき出しとなっているため、安全面と騒音の二つの問題があるため、設置場所の制限や、安全確保のための専有面積の確保が必要となっている。
合わせて構造上、回転軸受部分が風雨にさらされるケースが多く、それによりメンテナンスの頻度も高くなるという問題も抱えている。
そこで、本発明によって垂直軸型の効率を上げると同時に、安全装置として回転羽根を覆うことにより、防音対策と軸受の保護を同時に行い、より設置場所の自由度を上げ、小型化したものを多数設置することを可能にすることによる、発電効率の高効率化を図ることを課題とする。
小型水力発電の場合、水平軸型の場合、発電機を水中に沈めるか、水上に発電機を設置するには、傘歯車等により回転方向を変換しなければならず、構造的に複雑な上、効率の低下と製造コストの上昇が発生する。
また一機当たりの発電効率を上げるためには、羽根の面積を大きくする必要があり、それにより水平方向に専有面積が大きくなるので、木やゴミ等の浮遊物と接触する確率が高くなり、構造上回転羽根にそれらの浮遊物が直接接触することもあり、障害の発生率も高くなる。 In the case of the horizontal axis type, the power generation efficiency is good, but since the exclusive area is large, when installing multiple units, it is necessary to leave a space between each device. As a result, a large area is required to increase the efficiency. It becomes.
In the case of the vertical axis type, although there is an advantage in terms of installation area, the wind that acts in the direction of rotation and the wind that acts as a brake act simultaneously on the blades rotating on the vertical axis, so the power generation efficiency However, development is being promoted to solve the problem with various shapes.
Moreover, since both of the rotating blades are exposed, there are two problems of safety and noise. Therefore, it is necessary to limit the installation location and secure a dedicated area for ensuring safety.
In addition, there are many cases in which the rotary bearing part is exposed to wind and rain due to the structure, which also increases the frequency of maintenance.
Therefore, the present invention increases the efficiency of the vertical axis type and at the same time covers the rotating blades as a safety device, thereby simultaneously performing soundproofing measures and protecting the bearings, increasing the degree of freedom of installation location, and reducing the size It is an object to improve the power generation efficiency by making it possible to install.
In the case of small hydropower generation and horizontal axis type, in order to submerge the generator in the water or to install the generator on the water, the direction of rotation must be changed with a bevel gear, etc. As a result, the efficiency decreases and the manufacturing cost increases.
Also, in order to increase the power generation efficiency per machine, it is necessary to increase the area of the blades, thereby increasing the exclusive area in the horizontal direction, increasing the probability of contact with floating objects such as wood and garbage, Due to the structure, these floating objects may come into direct contact with the rotating blades, resulting in an increased failure rate.
以上の課題を解決するために、図1図2のような形状のカバーを取り付け、回転羽根を覆うことで、その形状により風向きに対して常に一定方向にカバーの向きを向けさせ、正面より受けた風をカバー内で羽根の回転方向に風が当たるよう誘導し、羽根を押す方向で力を与えると同時に、カバー側面から後端部分にかけて流れる、流速の上がった風によって生じる負圧を利用し、カバー内部で羽根の回転方向に力がかかるよう、吸い出す方向に誘導させることにより、回転羽根軸を中心にスワール渦を発生させ、カバーに当たる風を全方位から回転羽根を回転させる力に利用させる。
同時に、回転羽根を覆う事で、回転部分に直接接触することを防ぎ、回転羽根の風切り音も外部へ漏れることを防ぐと同時に、回転軸受が直接風雨にさらされることも防ぐ。
また風力発電の場合、回転羽根がむき出しのため、安全性の面から人や物から隔離する必要があり、設置場所がかなり限定されてきたが、小型でかつカバーで覆われていることから、設置場所についても自由度があがり、多数設置されていくことで、製造コストの低下とメンテナンスコストの低下にも貢献する。
小規模水力発電として使用する場合、本発明の装置を上下逆にし、カバーのスカート部分（発電機側）に浮力体を設け、その浮力体を鎖などで固定させて設置することで、発電機自体を水中に沈めることなく、回転羽根とカバーのみを水中に沈めることになるので、メンテナンス性にも優れ、また河川なのでの流木やゴミ等の浮遊物は、浮力体やカバーが直接回転羽根に当たるのを回避することになるので、故障の原因を軽減することにもつながる。
また発電効率を上げるためには、本発明の場合は垂直方向に回転羽根の長さを伸ばすことで、水平方向の幅を広げる必要がなく、複数設置したとしても水平方向の専有面積が小さいため、より高効率の小規模水力発電が可能となる。 In order to solve the above problems, a cover with a shape as shown in Fig. 1 and Fig. 2 is attached and the rotating blades are covered so that the direction of the cover is always directed in a certain direction with respect to the wind direction. The wind is guided in the direction of rotation of the blades in the cover and force is applied in the direction of pushing the blades, and at the same time, the negative pressure generated by the increased flow velocity of the wind from the side of the cover to the rear end is used. Inducing the swirl vortex around the rotating blade axis by guiding it in the sucking direction so that the force is applied in the rotating direction of the blade inside the cover, and using the wind hitting the cover as the force to rotate the rotating blade from all directions .
At the same time, by covering the rotating blades, it is possible to prevent direct contact with the rotating part, prevent wind noise from the rotating blades from leaking to the outside, and at the same time prevent the rotating bearings from being directly exposed to wind and rain.
Also, in the case of wind power generation, the rotating blades are exposed, so it is necessary to isolate them from people and things from the viewpoint of safety, and the installation location has been considerably limited, but because it is small and covered with a cover, The installation location is more flexible, and many installations contribute to lower manufacturing costs and lower maintenance costs.
When used as small-scale hydroelectric power generation, the device of the present invention is turned upside down, a buoyant body is provided on the skirt part (generator side) of the cover, and the buoyant body is fixed with a chain etc. Since only the rotating blades and the cover will be submerged in the water without submerging itself, it is excellent in maintainability, and floating objects such as driftwood and garbage in the river directly hit the rotating blades and the cover. Therefore, it is possible to reduce the cause of the failure.
In order to increase the power generation efficiency, in the case of the present invention, it is not necessary to increase the horizontal width by extending the length of the rotary blade in the vertical direction, and even if a plurality of installations are installed, the horizontal exclusive area is small. Higher-efficiency small-scale hydroelectric power generation becomes possible.

In order to increase the power generation efficiency, in the case of the present invention, it is not necessary to increase the horizontal width by extending the length of the rotary blade in the vertical direction, and even if a plurality of installations are installed, the horizontal exclusive area is small. Higher-efficiency small-scale hydroelectric power generation becomes possible.
本発明により、これまでの垂直軸型の場合、一部の風しか羽根の回転に利用できず、それ以外の風は逆にブレーキとならないような対策を施すものが多かったが、ブレーキとなる風を直接羽根にあてるないだけでなく、その風の負圧を利用して更に羽根の回転に利用できるため、発電効率が向上した。
また同時に、回転羽根を覆う事で、より安全性を確保すると同時に、羽根の風切音を低減させることができるため、これまで設置の難しかった場所への設置を可能とし、より小型化したものを多数設置させることが可能となるため、これまで設置できなかった場所への設置や、面積当たりの発電効率を向上させる。 According to the present invention, in the case of the conventional vertical axis type, only a part of the wind can be used for the rotation of the blades, and many other measures are taken to prevent the other wind from becoming a brake. Not only can the wind not be applied directly to the blades, but it can also be used to rotate the blades using the negative pressure of the wind, thus improving power generation efficiency.
At the same time, covering the rotating blades ensures more safety and at the same time reduces the wind noise of the blades, making it possible to install in locations where it was difficult to install so far, making it more compact As a result, it is possible to install a large number of power plants in a place that has not been able to be installed, and to improve the power generation efficiency per area.

軽量で剛性の高いプラスチック等の素材で、図のような形状のカバーを作成し、発電機にカバー軸受と、カバーの底の部分となるプレートを取り付ける。
次に発電機の回転軸に回転軸と回転羽根を取り付け、回転羽根を覆うように、カバーを被せ、底となるプレートとカバーを結合する。 Create a cover with the shape shown in the figure, using a lightweight, rigid plastic material, and attach the cover bearing and the plate that forms the bottom of the cover to the generator.
Next, the rotating shaft and the rotating blades are attached to the rotating shaft of the generator, the cover is put on the rotating blades, and the bottom plate and the cover are joined.

例えばガードレールの各支柱の上部や、信号機、中央分離帯、高速道路、鉄道線路等のフェンスの上部に複数取りつけることで、通常の風だけでなく、自動車や電車の走行による風を発電に活かすことができる。
また家の屋根やビルの屋上等に設置する際にも、専有面積が小さいので、小型軽量の物を複数取りつける事で、屋根への負担を軽減でき、設置コストを軽減することができる。
小規模水力発電としては、河川の橋脚などに本発明の装置に取りつけた浮力体とを鎖でつないで浮かせて使用すれば、多くの発電機を設置できる。
また水平方向の専有面積の小ささから、本発明の装置を直列に設置することもできるので、河川の流れに影響を与えず発電効率を上げることができる。 For example, by installing multiple units on the top of each guard rail post or on the fences of traffic lights, median strips, highways, railway tracks, etc., not only normal winds but also winds from driving cars and trains can be used for power generation. Can do.
Also, when installing on the roof of a house, the rooftop of a building, etc., since the exclusive area is small, the burden on the roof can be reduced by installing a plurality of small and lightweight objects, and the installation cost can be reduced.
As small-scale hydroelectric power generation, a large number of generators can be installed if a buoyant body attached to the apparatus of the present invention is connected to a bridge pier of a river with a chain and used.
Since the apparatus of the present invention can be installed in series because of the small area occupied in the horizontal direction, the power generation efficiency can be increased without affecting the flow of the river.

電力自由化とともに、エネルギーの地産地消が必要とされる中、地方自治体等により学校等の各公共施設の建物の屋上や、壁面に多数設置し、24時間発電できる仕組みを構築することで、原発のような大規模発電からの送電網による損失の無駄をなくすだけでなく、万が一の大規模災害時の送電網の復旧を待たず、避難場所での自家発電システムの構築が可能となり、災害対策にもなりえる。
また各河川の橋脚に小規模水力発電用に本発明の装置を設置し、小規模水力発電装置を多数設置させ、電力を安定的に供給させることができ、その際に橋の通路と反対面（裏面）にも風力発電装置を多数設置させることができるので、一つの橋で水力・風力の両方から電気を生み出すことができ、エネルギーの地産地消につながる。
ガードレールや中央分離帯、信号機や道路標識、高速道路や鉄道のフェンスの上部に多数設置させ、通常の風だけでなく、自動車・鉄道の走行による風を取り込み発電・蓄電を行い、その作られた電気から夜間の照明に使用することで、夜間での交通事故の減少につなげる。
各家庭に自家発電装置として販売する場合においても、天候に左右されるデメリットなく、太陽光発電のように屋根の向きや日当たりとは関係なく、専有面積も小さいことから安価に複数台設置することができるため、各家庭への普及が見込まれる。
またカバーによる安全性の確保によって、設置場所の自由度が増すため、マンション・アパートのような集合住宅においても、ベランダ等に設置することもできるので、一つの建物に対して、多様な設置場所を可能となるため、ビル風を利用した発電も可能となる。
農業においても、専有面積が小さいことから、大きな日照の妨げにならないことで、多数の発電装置を設置することができるので、太陽光発電のように広大な土地を使うことなく、農地との併用で発電装置を広げていくことができ、売電による農家の副収入として農業の疲弊を防止させる。
漁業においても、船舶上に設置した風力発電により常時蓄電させることで、船舶エンジンの発電に消費されるエネルギーを抑える。
また漁港など海辺は風も強く、専有面積の小さい本発明の装置であれば、多数設置することができるので、その売電による副収入が、疲弊した海沿いの地域の活性化にもつながる。 Along with the liberalization of electric power, the local production and consumption of energy is required, and by constructing a system that can be installed on the rooftops and walls of public facilities such as schools, etc. In addition to eliminating loss of power loss from large-scale power generation such as nuclear power plants, it is possible to construct a private power generation system at an evacuation site without waiting for restoration of the power transmission network in the event of a large-scale disaster. It can be a countermeasure.
In addition, the device of the present invention is installed for small-scale hydroelectric power generation on the pier of each river, and a large number of small-scale hydroelectric power generation devices can be installed to supply power stably. Since many wind power generators can be installed on the back side, electricity can be generated from both hydropower and wind power on a single bridge, leading to local production and consumption of energy.
Many were installed on the top of guardrails, median strips, traffic lights, road signs, highways and railway fences, and not only normal winds but also winds generated by driving cars and railways to generate and store electricity. By using it for lighting at night from electricity, it will reduce the number of traffic accidents at night.
Even when selling as an in-house power generation device to each home, there are no demerits that are affected by the weather. Can be spread to each household.
In addition, because the safety of the cover increases the degree of freedom of installation location, it can also be installed on a veranda etc. in apartment buildings such as apartments and apartments, so various installation locations for one building Therefore, it is possible to generate electricity using building wind.
Even in agriculture, since the exclusive area is small, a large number of power generation devices can be installed by not interfering with large sunlight, so it can be used together with farmland without using vast land like solar power generation. In this way, the power generation equipment can be expanded, and agricultural exhaustion can be prevented as a secondary income from farmers selling electricity.
Even in the fishery industry, the energy consumed by the power generation of the ship engine is suppressed by always storing electricity by wind power generation installed on the ship.
In addition, since the seaside such as a fishing port has strong winds and can be installed in large numbers with the device of the present invention having a small exclusive area, the secondary income from the power sale leads to the activation of the area along the exhausted sea.
また各河川の橋脚に小規模水力発電用に本発明の装置を設置し、小規模水力発電装置を多数設置させ、電力を安定的に供給させることができ、その際に橋の通路と反対面（裏面）にも風力発電装置を多数設置させることができるので、一つの橋で水力・風力の両方から電気を生み出すことができ、エネルギーの地産地消につながる。
ガードレールや中央分離帯、信号機や道路標識、高速道路や鉄道のフェンスの上部に多数設置させ、通常の風だけでなく、自動車・鉄道の走行による風を取り込み発電・蓄電を行い、その作られた電気から夜間の照明に使用することで、夜間での交通事故の減少につなげる。
各家庭に自家発電装置として販売する場合においても、天候に左右されるデメリットなく、太陽光発電のように屋根の向きや日当たりとは関係なく、専有面積も小さいことから安価に複数台設置することができるため、各家庭への普及が見込まれる。
またカバーによる安全性の確保によって、設置場所の自由度が増すため、マンション・アパートのような集合住宅においても、ベランダ等に設置することもできるので、一つの建物に対して、多様な設置場所を可能となるため、ビル風を利用した発電も可能となる。
農業においても、専有面積が小さいことから、大きな日照の妨げにならないことで、多数の発電装置を設置することができるので、太陽光発電のように広大な土地を使うことなく、農地との併用で発電装置を広げていくことができ、売電による農家の副収入として農業の疲弊を防止させる。
漁業においても、船舶上に設置した風力発電により常時蓄電させることで、船舶エンジンの発電に消費されるエネルギーを抑える。
また漁港など海辺は風も強く、専有面積の小さい本発明の装置であれば、多数設置することができるので、その売電による副収入が、疲弊した海沿いの地域の活性化にもつながる。 Along with the liberalization of electric power, the local production and consumption of energy is required, and by constructing a system that can be installed on the rooftops and walls of public facilities such as schools, etc. In addition to eliminating loss of power loss from large-scale power generation such as nuclear power plants, it is possible to construct a private power generation system at an evacuation site without waiting for restoration of the power transmission network in the event of a large-scale disaster. It can be a countermeasure.
In addition, the device of the present invention is installed for small-scale hydroelectric power generation on the pier of each river, and a large number of small-scale hydroelectric power generation devices can be installed to supply power stably. Since many wind power generators can be installed on the back side, electricity can be generated from both hydropower and wind power on a single bridge, leading to local production and consumption of energy.
Many were installed on the top of guardrails, median strips, traffic lights, road signs, highways and railway fences, and not only normal winds but also winds generated by driving cars and railways to generate and store electricity. By using it for lighting at night from electricity, it will reduce the number of traffic accidents at night.
Even when selling as an in-house power generation device to each home, there are no demerits that are affected by the weather. Can be spread to each household.
