Abstract

A wind turbine is provided to reduce increasingly weight of rotating body composed of a blade and a wheel, and improve supporting capacity against strong wind. A wind turbine improves supporting capacity of a blade against strong wind by additionally installing a split wheel(7) dividing the length of a blade in half. A bearing outer panel(12) onto which a semi-circular type rib(13) is attached on the inner and outer side of a rotating shaft inserted into a fitting hole of a rotating shaft(9) penetrating the split wheel. A blade outer panel(6a) is fixed onto a number of ribs inserted into the rotating shaft and an auxiliary supporting rod(11,11').

Description

풍력발전기{Wind turbine}Wind Turbine

도1은 풍력발전기의 사시도.1 is a perspective view of a wind turbine.

도2는 블레이드의 분할 연결부분을 절개 투시한 사시도.Figure 2 is a perspective view of the cut through the split connection of the blade.

도3은 블레이드의 분할 연결부분 단면도.3 is a cross-sectional view of a divided connection of the blade.

도4는 블레이드의 분할 연결부분 분해사시도.Figure 4 is an exploded perspective view of the divided connection portion of the blade.

블레이드와 대형 휠 등으로 구성된 회전체를 좀 더 경량화하면서도 강풍에 대한 저항과 지지능력을 강화할 수 있게 한다.Rotors composed of blades and large wheels can be made lighter, while also improving wind resistance and support.

본인이 발명하여 출원한 다중블레이드 방식의 풍력발전기(19-2007-0026499)는 도1에서 타워 A 상단에 수평 회전 자재케 된 나셀 ① 후단으로 도출된 회전축 ② 주연에 고설 된 수개의 로-터 ③ 외주선단에 고설된 내외 측 휠 ④④' 에 다수의 블레이드 ⑥을 착설케 한 것이었다.The multi-blade wind power generator (19-2007-0026499), which was invented and filed by me, has a horizontal rotating material on the top of tower A in Fig. 1. Many blades ⑥ were installed on the inner and outer wheels ④ 'installed at the outer periphery.

그러나 본인의 선출원에서는 강풍에 대비하여 블레이드에 대한 지지력과 블레이드 자체를 경량화하면서도 강풍에 대한 저항능력을 향상시킬 필요성이 제기되 었다.However, my earlier application raised the need to improve the bearing capacity against the wind and the weight of the blade itself while improving the resistance against the wind.

본 발명에서는 블레이드의 길이를 절반으로 분할하는 분할 휠⑦을 추가하여 착설함으로써 강풍에 대한 블레이드 ⑥의 지지능력을 향상시키고, 블레이드의 구조도 경량화하면서도 강풍에 대한 저항능력을 강화케 한 것으로 도면에 따라 상세히 설명하면 아래와 같다.In the present invention, by adding and installing a split wheel ⑦ that divides the length of the blade in half to improve the bearing capacity of the blade ⑥ against strong winds, and to reduce the weight of the blade structure while strengthening the resistance to strong winds according to the drawings Detailed description is as follows.

분할 휠 ⑦의 내측면과 외측면에는 동형의 원통형 형태인 얕은 깊이의 ⑧⑧' 를 형성하고 중앙에 블레이드 ⑥의 회전축 겸 지지봉 ⑨의 삽설공 ⑨a가 내외측으로 관통되게 천공되어 볼베어링 ⑩의 기판을 형성하였고, 중앙에 회전축 ⑨의 삽설공 ⑨b와 보조지지봉 ⑪⑪'의 삽설공 ⑪a⑪a'가 천공된 원반형의 베어링 외판 ⑫는 낮은 높이의 원주형으로 요구 ⑧⑧'보다 약간적은 직경의 상부와 직경이 축소된 하부단층 ⑬a를 형성하여 베어링 외판 ⑫⑫'를 요구 ⑧⑧'에 삽입하고 축소된 단층⑫a와 요구 ⑧⑧' 저부 내주연간에 볼베어링 ⑩이 삽설되어 수평회전 베어링을 형성케 하였다.On the inner side and the outer side of the split wheel ⑦, ⑧⑧ 'of shallow depth was formed in the shape of a cylindrical shape, and the insertion hole ⑨a of the rotating shaft and the supporting rod ⑨ of the blade ⑥ was drilled through the inside and the outside to form the substrate of the ball bearing ⑩. The disc-shaped bearing shell 된 with the insertion hole ⑨b of the rotating shaft ⑨ in the center and the insertion hole ⑪a⑪a 'of the auxiliary support rod ⑪⑪' is a lower-height cylindrical type with a lower upper layer with a diameter slightly smaller than the required ⑧⑧ ' ⑬a was formed to insert the bearing shell ⑫⑫ 'into the required ⑧⑧', and a ball bearing ⑩ was inserted between the reduced monolayer ⑫a and the inner circumference of the bottom of the required ⑧⑧ 'to form a horizontal rotating bearing.

반달형의 리-브 ⑬은 외측주연에 테두리 ⑬a를 형성하여 요구형을 형성하였으며, 베어링외판 ⑫와 동일하게 회전축 삽설공 ⑬b와 보조지지봉 삽설공 ⑬c가 천공되어 지지봉 ⑨와 보조지지봉 ⑪⑪'를 삽설한 후 낫트 ⑭⑭'등으로 베어링외판 ⑫에 견고하게 고착시켰다.The half-moon rib 브 테두리 formed the required shape by forming the edge ⑬a on the outer circumference, and the supporting rod ⑨ and the auxiliary support rod ⑪⑪ 'were inserted by drilling the rotary shaft inserter ⑬b and the auxiliary support rod inserter ⑬c in the same way as the bearing shell ⑫. After that, it was firmly fixed to the bearing shell 으로 with a nat ⑭⑭ '.

지지봉 ⑨와 보조지지봉 ⑪⑪'에는 일정한 간격으로 다수의 리-브 ⑬을 삽설 고착시킴으로써 블레이드 ⑥의 뼈대를 형성케 하였으며 여기에 비교적 얇고 경량재 질의 판재 ⑥a를 덧씌워서 리-브 테두리 ⑬a에 고착시킴으로써 강풍에 강력하게 저항할 수 있는 블레이드 ⑥을 완성할 수 있게 하였다. 분할 휠 ⑦ 저부에는 연장된 로-토 ③과 견고하게 연설하여 회전축겸 지지봉 ⑨와 로-토 ③이 분할 휠⑦을 견고하게 지지할 수 있게 하였다.The support rod ⑨ and the auxiliary support rod ⑪⑪ 'were inserted and fixed to the rib 일정한 at regular intervals to form the armature of the blade ⑥, which was covered with a relatively thin and lightweight plate ⑥a, and fixed to the rib rim ⑬a. It was possible to complete the blade ⑥ that can resist strongly. At the bottom of the split wheel ⑦, it was firmly spoken by the extended ro-to ③ so that the rotating shaft and support rods ⑨ and ro-to ③ could firmly support the split wheel⑦.

블레이드 ⑥의 길이를 절반정도로 분할하는 위치에서 분할 휠 ⑦에 의해서 블레이드 ⑥을 견고하게 지지케함으로써 블레이드 ⑥의 지지력 향상에 큰 효과를 얻게 되었다.The blade ⑥ was firmly supported by the dividing wheel ⑦ at the position where the length of the blade ⑥ was divided in half, and thus the effect of improving the bearing capacity of the blade ⑥ was obtained.

반달요구형의 리-브 ⑬이 고설된 베어링외판 ⑫에 회전축겸 지지봉 ⑨와 보조지지봉 ⑪⑪'을 삽설하고, 지지봉 ⑨와 보조지지봉 ⑪⑪'에 일정한 간격으로 삽설된 다수의 리-브 ⑬의 테두리 ⑬a에 블레이드 외판 ⑥a를 고착시킴으로써 비교적 얇은 판재 ⑥a를 사용하고도 강풍에 대한 블레이드 ⑥의 지지력 향상에 최상의 조건을 갖추게 되었다.Rotating shaft and support rod ⑨ and auxiliary support rod ⑪⑪ 'are inserted into the bearing shell 된 with semi-required rib ribs ,, and the edges 브 a of multiple ribs-installed at regular intervals on the support rod ⑨ and auxiliary support rod ⑪⑪'. By fixing the blade outer shell ⑥a on the surface, the optimum conditions for improving the bearing capacity of the blade ⑥ against strong winds are achieved even when a relatively thin sheet ⑥a is used.
