発明の名称 (英語) SAVONIUS WIND POWER GENERATION DEVICE AND CONTROL METHOD THEREFOR NEW
発明の概要(英語) [Problem] To provide a wind power generation device that is provided with multi-stage Savonius windmills in the front-and-rear direction, and that enables the windmills to rotate efficiently against wind from any direction and improves power generation efficiency. [Solution] Three wind power generation units 200A-200C each having two Savonius windmills 210 disposed side by side are arranged so as to form a substantially equilateral triangle. A narrow space S is provided between the windmills at the front stage with respect to a wind direction W1, wind power passing from the front to the rear is received by inner wind-receiving buckets 213 so that the windmill on one side rotates clockwise and the windmill on the other side rotates counterclockwise. At the middle stage, wind power passing from the front is received by outer wind-receiving buckets so that the windmill on one side rotates counterclockwise and the windmill on the other side rotates clockwise. At the rear stage, the wind power having passed through the space S at the front stage is received by inner wind-receiving buckets so that the windmill on one side rotates clockwise and the windmill on the other side rotates counterclockwise. Further, in a view from the front, each of the inner wind-receiving buckets at the middle stage partially overlaps the outer wind-receiving bucket on the same side at the front stage, and each of the outer wind-receiving buckets at the rear stage partially overlaps the inner wind-receiving bucket on the same side at the front stage.
特許請求の範囲(英語) [claim1]
1. Turning the saboniusu type pinwheel, being the saboniusu type generating set which generates electricity, as for the aforementioned saboniusu type pinwheel, the end plate of the top and bottom which keeps the vertical axis and the particular vertical axis and the curve inside of circular arc condition putting the aforementioned vertical axis, identical rotation direction as it faces, having two receiving wind buckets which are kept between the end plates of the aforementioned top and bottom,
The aforementioned saboniusu type pinwheel each left and right is arranged 2 by the front step and the latter part,
The front step the opening of narrow width is provided between the pinwheels left and right and the inside approaching each receives the wind force which from the front is passed on back and the wind bucket appeals and another side turns on the one hand clockwise counterclockwise,
After passing the aforementioned opening of the front step, the wind force the inside approaching each it receives the latter part and the wind bucket appeals and another side turns on the one hand clockwise counterclockwise,
Furthermore, as for the latter part vis-a-vis the front step in order for the receiving wind bucket of the outside approaching of the latter part to be piled up with the receiving wind bucket of the inside approaching of the same side of the front step partly considered as the front, arranging, the saboniusu type wind force generating set which features that it becomes.
[claim2]
2. The aforementioned saboniusu type pinwheel left and right 2 is arranged by the front step and sublevel between the latter part,
The outside approaching each it receives sublevel and receiving the wind force which the wind bucket from the front passes on back, another side turns on the one hand counterclockwise clockwise,
Furthermore, in order sublevel the inside approaching of sublevel each receives considered as the front vis-a-vis the front step and for the wind bucket to be piled up with the receiving wind bucket of the outside approaching of the same side of the front step partly, arranging, the saboniusu type wind force generating set of the claim 1 statement which features that it becomes.
[claim3]
3. Plane surface apparent doing the wind force generation of electricity unit of 3 sets which line up 2 saboniumu type pinwheels, in order to become abbreviation triangle altogether, arranging, it becomes, 2 pinwheels forward become the front step vis-a-vis wind direction, 2 pinwheels back become the latter part, the saboniusu type wind force generating set of the claim 2 statement which features that 2 pinwheels of the center become sublevel.
[claim4]
4. In order for interior angle between the wind force generation of electricity unit which adjoins the wind force generation of electricity unit of the aforementioned 3 sets, to reach abbreviation 60 degree, plane surface apparent doing, in order to become abbreviation regular triangle altogether, arranging, the saboniusu type wind force generating set of the claim 3 statement which features that it becomes.
[claim5]
5. The support section and the front step and lying between each pinwheel or the front step of the latter part, and the wind force generation of electricity section and the aforementioned support section and the aforementioned wind force generation of electricity section which include each pinwheel of sublevel and the latter part between in combination with the aforementioned wind force generation of electricity section to the leading direction of the wind, way it becomes optimum wind direction arrangement, the time the claim 1 which features that it has the rotary section which is made to move or either of claim 4 in one section the saboniusu type wind force generating set of statement.
[claim6]
6. By the support section and the front step and the latter part or arranging left and right 2 saboniumu type pinwheels each by the front step, and sublevel and the latter part in the saboniumu type wind force generating set which has the rotary section and the control section which lie between the wind force generation of electricity section and the aforementioned support section and the aforementioned wind force generation of electricity section which become,
When leading direction of the wind differs from the optimum wind direction arrangement of the aforementioned wind force generation of electricity section, way the aforementioned control section, calculates the direction of leading direction of the wind the inside either wind direction information from the anemoscope, wind distribution information from the wind rose or information of generation of electricity every of pinwheel on the basis of the combination of one item of information or plural information, gives the time dynamic indication to the rotary section on the basis of particular calculation value, leading direction of the wind matches the optimum wind direction arrangement of the aforementioned wind force generation of electricity section, control method of the saboniusu type wind force generating set which features that the time it makes move aforementioned wind force generation of electricity section.
