Wherein,
1, wind-collecting cover, 2, electromotor, 3, blade, 4, tail vane, 5, bracing frame, 6, turn.
Detailed description of the invention
The present embodiment provides a kind of wind collection type wind driven generator, the electromotor 2 including wind-collecting cover 1, being arranged in wind-collecting cover 1 and the blade 3 of the rotating shaft assembly connection with electromotor 2, described wind-collecting cover 1 two ends offer the first opening and the second opening respectively, the sectional area of described first opening is more than the sectional area of the mid portion of wind-collecting cover 1, the position at the sectional area minimum of the mid portion that described blade 3 is positioned at wind-collecting cover 1.The sectional area of the first opening is bigger, wind area can be expanded, more is distinguished and admirable in the first opening enters into wind-collecting cover 1, distinguished and admirable in wind-collecting cover 1 at bigger the first opening part of sectional area to the sectional area minimum of mid portion, according to hydromechanical principle, fluid flow to from the place that opening section area is big opening section area little local time, the flow velocity of fluid can raise.Therefore, the position at the sectional area minimum of wind-collecting cover 1 mid portion, distinguished and admirable speed is the highest, and the rotating speed of blade 3 is the fastest, and then drives the rotary speed of electromotor 2 faster, makes the generating efficiency of electromotor 2 be improved.The sectional area of the second opening of wind-collecting cover 1 is more than the sectional area of the mid portion of wind-collecting cover 1, it is distinguished and admirable after band moving vane 3 at the sectional area minimum of wind-collecting cover 1 mid portion rotates, the sectional area of wind-collecting cover 1 increases again, distinguished and admirable wind-collecting cover 1 can be flowed out faster after making band moving vane 3 rotate, prevent distinguished and admirable delay in wind-collecting cover 1 from hindering follow-up distinguished and admirable entrance wind-collecting cover 1, thus improve the wind flow entered in wind-collecting cover 1, and then improve generating efficiency.Blade 3 blade in the present embodiment is relatively small, easy to manufacture, and makes the compact overall structure of wind collection type wind driven generator.Blade 3 is positioned in wind-collecting cover 1, makes blade 3 be not directly exposed to outside, accordingly even when the setting height(from bottom) of wind collection type wind driven generator is limited, and also will not be dangerous to the personnel component of surrounding.
The shape of wind-collecting cover 1 is optimized by the present embodiment further: the medial surface at the sectional area minimum of the first opening of wind-collecting cover 1 to mid portion is shaped as paraboloid, and the medial surface at the sectional area minimum of the second opening of wind-collecting cover 1 to mid portion is shaped as paraboloid.When medial surface at Experimental Comparison, the sectional area minimum of the first opening of wind-collecting cover 1 to mid portion is shaped as paraboloid, distinguished and admirable can enter into quickly in wind-collecting cover 1；Second opening of wind-collecting cover 1 to the medial surface at the sectional area minimum of mid portion is shaped as paraboloid, and wind-collecting cover 1 is flowed out in the distinguished and admirable meeting after band moving vane 3 rotates faster.The equation assuming paraboloid is normal equation: x2/a2+y2/b2=2z, works as a2=b2Time, the normal equation of paraboloid just becomes the normal equation of the paraboloid of revolution: x2+y2=2a2z.Medial surface at further Experimental Comparison, the sectional area minimum of the first opening of wind-collecting cover to mid portion is shaped as the paraboloid of revolution, distinguished and admirable can enter into quickly in wind-collecting cover 1；Second opening of wind-collecting cover to the medial surface at the sectional area minimum of mid portion is shaped as the paraboloid of revolution, and wind-collecting cover 1 is flowed out in the distinguished and admirable meeting after band moving vane 3 rotates faster.
Above-mentioned wind collection type wind driven generator may be mounted in roof or the body of wall of draught, now has only to wind-collecting cover 1 and roof are fixedly mounted or built in body of wall, it is achieved that the flexible of wind collection type wind driven generator is installed and use.The present embodiment can also utilize the shape of wall structure wind-collecting cover 1, realizing on the normal working foundation of wind collection type wind driven generator, reduce cost and put into.If make above-mentioned wind collection type wind driven generator be arranged at the air port of open field, now it is accomplished by assembly connection tail vane 4 on electromotor 2, wind-collecting cover 16 is movably attached on bracing frame 5 through turning, tail vane 4 makes wind collection type wind driven generator regulate angle according to wind direction, making blade 3 all the time facing to the direction that the wind comes from thus obtain the wind energy of maximum, turning 6 can make wind-collecting cover 1 rotate to realize the function of tail vane 4 adjustment direction neatly.
Certainly; described above is not to restriction of the present utility model; this utility model is also not limited to the example above, change that those skilled in the art are made in essential scope of the present utility model, retrofits, adds or replaces, and also should belong to protection domain of the present utility model.
