Description

Wandering star axle windmill

Technical field

The utility model relates to a kind of mechanical device, particularly a kind of wandering star axle windmill.

Background technique

Existing windmill is an oar formula generator, blade is divided into two leaves, three leaves and four leaves, being subjected to wind-force to promote blade by the blade face and rotating, is the effect of electric power thereby reach wind power transformation, so wind blade face diameter directly determines the running speed and the efficient of the blade of windmill.With three oars is example, and its three blades are very narrow, the area sum less than with the blade be radius the area of a circle 10%, allow wind push away its rotation, and every blade must form an angle to distortion on the one hand with the wind-force direction, produce a component, so 5 % that his wind utilization ratio has only the front the wind comes from more, four leaves or multileaf type, wind-exposuring area is big, but the increase structure of blade is relative complex also, the weight of fan own is also higher, and receiving the wind-force resistance increases, and has influenced the rotating speed of generator.

The model utility content

The purpose of this utility model is to overcome existing deficiency and provides a kind of simple in structure, the wind utilization ratio high wandering star axle windmill.

The purpose of this utility model is achieved by adopting following technical proposals:

A kind of wandering star axle windmill, comprise support arm, inner support and the output shaft that is packed on the described support arm, described inner support is connected with described output shaft and rotates around described output shaft, one end of described output shaft is equipped with first gear that is packed on the described support arm, the control gear that a plurality of blades is installed and is connected on the described inner support with blade, described blade pass is crossed first rotating shaft that is installed on the described inner support and is connected with inner support, described control gear comprises second gear, second rotating shaft, the 3rd gear, gearshift, first sprocket wheel, second sprocket wheel, described second rotating shaft, one end is installed in described inner support, the other end is fixed with second gear, the middle part is equipped with second sprocket wheel, described second gear and described first gear engagement, described gearshift is installed in described first rotating shaft, described gearshift is controlled the conversion that is connected of first rotating shaft and the 3rd gear and first sprocket wheel, described the 3rd gear and described second gear engagement, described first sprocket wheel is connected with described second sprocket wheel by chain.

In the utility model, the diameter of described first gear is identical with described the 3rd gear with the number of teeth, and the diameter of described second gear is 1/2 of described first gear.

In the utility model, the control gear that six blades is installed on the described inner support and is connected with blade, described six blades are evenly distributed on described inner support.

In the utility model, described two retaining gearshifts comprise the gearshift slip teeth; rocker arm support; gearshift track; gearshift rocking arm; described rocker arm support is installed on the described inner support; the lower end of described rocker arm support is hinged with " 7 " the gearshift rocking arm of font, described gearshift slip teeth is sleeved in described first rotating shaft, one end of described gearshift rocking arm is connected with described gearshift slip teeth and can stirs described gearshift slip teeth and slides up and down, the other end of described gearshift rocking arm is installed in the described gearshift track, described gearshift track is divided into first track, second track, the 3rd track, the 4th track, described first track, second track, the 3rd track, the 4th track is interconnected.

Adopt such scheme, utilize the cooperation of gear, at first inner support rotates around output shaft under the drive of wind-force, when blade when entering the right semi-circle of this device, the gearshift rocking arm is when first track enters second track, because second race way diameter is less than first track, therefore the rocking arm of shifting gears moves upward and drives the gearshift slip teeth and be connected with first sprocket wheel, gear idle running in this time the 3rd, and second gear driven, second rotating shaft rotation time drives the rotation of second sprocket wheel, second sprocket wheel drives the rotation of first sprocket wheel, first sprocket wheel revolves and drives first rotating shaft rotation again, the sense of rotation of first rotating shaft this moment is consistent with second rotor shaft direction, make blade just vertical with wind direction in the right semi-circle rotation, when blade with after wind direction is vertical, the gearshift rocking arm just enters the 3rd track from second track, because second race way diameter is less than the 3rd track, therefore the rocking arm of shifting gears moves downward drive gearshift slip teeth and is connected with the 3rd gear with the disengaging of first sprocket wheel, first sprocket wheel idle running this moment, because first gear is fixing all the time, therefore second gear rotates around first gear and drives second rotating shaft and the rotation of the 3rd gear simultaneously, described the 3rd gear and the second gear counterrotating, the 3rd gear drives first rotating shaft rotation again, because the proportionate relationship of gear diameter, make blade remain the state vertical with wind direction, when blade when going out this device right semi-circle soon, the gearshift rocking arm enters the 4th track from the 3rd track, because the 3rd race way diameter is greater than the 4th track, therefore the rocking arm of shifting gears moves upward and drives the gearshift slip teeth and be connected with first sprocket wheel with the disengaging of the 3rd gear again, same as above, make blade get back to the initial state parallel with wind direction, when blade with after wind direction is parallel, the gearshift rocking arm just enters into first track from the 4th track, the gearshift rocking arm moves downward drive gearshift slip teeth and is connected with the 3rd gear with the disengaging of first sprocket wheel again, same as above, make blade keep the state parallel to turn round at the left side of this device one side of something with wind direction, circulation thus, adopt this mode, make blade only vertical with wind direction in a side of device, and opposite side is parallel with wind direction, reduced the resistance of wind, increased the area of contact of blade and wind, wind utilization ratio height.
