Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in fig. 1, blade be by blade frame 1, blade frame 4. page block 7 formations in page fixing point .6, the blade in page fixing point 3, the blade in page or leaf 5, the blade in page or leaf 2, the blade in blade frame .8, blade frame .9, the blade.When blade frame 4 was fixed on the vertical shaft, blade frame 4 was the nearly vertical axle head of blade frame, and blade frame 1 is a blade frame vertical axle head far away.Page fixing point 3 is on blade frame 8 in the blade, and the interior page fixing point 6 of blade and lays respectively at 1/3rd places of blade frame 8, blade frame 9 length on blade frame 9., and all at blade frame 4 far-ends.In the blade in page fixing point 3, the blade axis vertical center line of page fixing point 6 page or leaf in the blade is divided into size is page or leaf 2, interior page 5 two-part of blade in 1: 2 the blade.
In Fig. 2, when blade frame 4 was fixed, blade was subjected to doing the time spent perpendicular to blade wind-force.Because page or leaf 2 areas are little in the blade, page or leaf 5 areas are big in the blade, produce resistance difference, in the blade page or leaf can be in the blade of wind-force effect lower edge in page fixing point 3 and the blade axis vertical center line clockwise direction of page fixing point 6 in blade frame, open, page or leaf is not subjected to stopping of page or leaf block 7, the interior page block 8 of blade in the blade in the blade.The barrier effect of page or leaf block 8 in page or leaf block 7 blades has guaranteed that page or leaf can counterclockwise not opened along the axis vertical center line of page fixing point 6 in page fixing point in the blade 3, the blade in the blade in the blade.
In Fig. 3, when blade frame 4 is fixed on the vertical shaft 8, blade is during perpendicular to vertical shaft 8 and the blade B position vertical with wind direction, when blade is subjected to doing the time spent perpendicular to blade wind-force, it is big that the interior page or leaf of blade 5 areas receive wind resistance greatly, page or leaf 2 areas are subjected to wind resistance little for a short time in the blade, page or leaf can be with page fixing point in the blade 3 in the blade, the axis vertical center line of page fixing point 9 turns clockwise in the blade, but because page or leaf block 6 (the page or leaf back side in the blade shown in the figure) is subjected to blade frame 1 in the blade, page or leaf block 7 is subjected to stopping of blade frame 4 in the blade, it is stressed that blade is forced in closed state, blade and wind resistance maximum can drive vertical shaft 8 with vertical shaft 8 vertical center line directions and move counterclockwise.When blade is being parallel to wind direction and during perpendicular to the C position of vertical shaft 8, blade does not stress, when blade movement is crossed the C position, blade continues to be subjected to the wind-force effect, but at this moment blade is interior page 2,5 two-part are stressed does not wait for page or leaf in the blade, can produce the interior page or leaf of blade with page fixing point in the blade 3, the power that the axis vertical center line of page fixing point 9 is counterclockwise opened in the blade, page or leaf block 6 in the blade, page or leaf block 7 is not subjected to blade frame 1 in the blade, stopping of blade frame 4, the page is parallel with wind direction in the blade, it is vertical with wind direction perpendicular to vertical shaft 8 and blade blade promptly to occur, the mode bit A of page or leaf and wind direction parallel opening in the blade.Blade moves to blade counterclockwise from the C position parallel with wind direction and the 180 degree mode bit during in the same way perpendicular to vertical shaft 8 are interval, page or leaf is an opening state in the blade, the situation of this blade windage minimum exists always, and blade is parallel with wind direction and to move to 180 degree of C position counterclockwise perpendicular to vertical shaft 8 mode bits in the same way interval from blade, blade is a closed state always, and the resistance of blade and wind is in one by the maximum process that diminishes of little change.So under the wind-force effect, blade moves to blade counterclockwise from the C position parallel with wind direction and the degree of 180 during in the same way perpendicular to vertical shaft 8 mode bits is interval, parallel with blade and to move to 180 degree of C position counterclockwise perpendicular to vertical shaft 8 in the same way interval with wind direction, these two interval blades are strong poor to the power that rotates counterclockwise with vertical shaft 8 vertical center line directions that vertical shaft 8 produces, and can produce to promote vertical shaft 8 and drive the power that vertical shaft 8 rotates counterclockwise (Fig. 3 describe be the schematic representation of a slice blade different azimuth on vertical shaft) with the vertical center line direction of vertical shaft 8 under the wind-force effect.When supposing to have two blades to be separately fixed at the B position of vertical shaft 8 and A position, B position blade is that closed state is subjected to that windage is big, A position blade is that opening state is subjected to windage little, just can allow vertical shaft 8 rotate counterclockwise with the vertical center line direction of vertical shaft 8.
