Description

Windmill

The present invention relates to have a windmill with the concentric cylindrical body of windmill running shaft, at the two ends of cylindrical body a circular end plate is arranged respectively, awe has the streamlined external form of a bending, it is contained on the running shaft that be arranged in parallel near two end plate peripheries, with the windmill running shaft, and its angle of swing is restricted.

DE-OS 2718608 discloses a kind of propeller generator, and this wind-driven generator has a cylindrical body, two end plate and a plurality of cylindrical body sectors that are installed in the cylindrical body two ends.This sector or the wing are contained on the running shaft that be arranged in parallel near the end plate periphery, with the wind-driven generator running shaft.Each sector around one parallel with the wind-driven generator running shaft but rotate with the asymmetric running shaft in covering of the fan center, and make like this wider portion of covering of the fan can center on one can limited adjustment angle (until 90 °) freedom to inner rotary.Stretch out outside the profile of wind-driven generator in covering of the fan wider portion under the state that outwards produces, and narrower part puts in the profile.When vertical wind driven generator ran into level distinguished and admirable, that sector that running shaft is in behind the wind direction was just outwards swung towards wind direction from the cylinder profile of wind-driven generator.Act on wind on this face and hold up power and just rotate whole cylindrical systems, next whereby covering of the fan just enters distinguished and admirable and outside swing.The distinguished and admirable sector that nuzzles up on that side of the system of pendulum position outside facing, thus running shaft is positioned at the front.

This known wind-driven generator rotates along the afterbody aspect of sector.This just causes this sector to play effect resemble the blade, so the whole wind power generator has the function of an impeller.Can make the maximum speed of this known wind-driven generator and wind speed suitable in addition.Therefore rotating speed and efficient depend on the wind speed that directly flows through to a great extent.

In a vertical shaft rotor known by DE-GM8228078, two lateral extensometers are arranged to the disk of rotor shaft be arranged on the rotor blade of the parallel to an axis between two disks, rotor blade always can be freely to rotate around the rotatingshaft setting that is parallel to rotor shaft.In addition each rotor blade is provided with a block, roughly radially is fixed in its position with aiming near the block that is installed by this block rotor blade.Realize whereby, only in each revolving process of spindle rotor, fixed facing to promoting distinguished and admirable pressure, also only do not entered a minimum air flow resistance positions with freely swinging by the rotor blade of resistance of air swing and do not participate in driving directly to driving useful rotor blade.

This has also determined the high energy of rotating speed of this vertical shaft rotor to reach the wind speed that directly flows through accordingly.

Task of the present invention is to improve the windmill of the described existing type of beginning, and windmill of the present invention rotates in wind should be particularly advantageous and extra high efficient is arranged, and has nothing to do with the wind speed that directly flows through to a great extent.

Task of the present invention is to solve like this: install four awes that bend flow line style external form is arranged at least with the circumference spacing that equates on the circumference of this windmill, these fronts have the awe of head to be installed in rotation on the running shaft and in the scope between end plate edge and cylindrical body to rotate.

Finished a kind of cartridge type windmill of the above-mentioned type in this manner, this windmill rotates along the cephalad direction of awe.This means that simultaneously awe is only rotated in the scope between end plate edge and cylindrical body, and does not outwards rotate from the cylindrical profile of windmill.The rotating speed of windmill can be greater than wind speed for this reason.Therefore this windmill rotates in wind and is particularly advantageous and very high efficient is arranged.

And in a kind of structure of the present invention, the inner distance between awe head and the adjacent awe afterbody can approximate the inner distance between awe head and the cylindrical body greatly.Guarantee that whereby the wind energy that flows to windmill from the side easily enters windmill and flows through this windmill.Go into the position windmill is applied a pressure distinguished and admirable whereby, and go out the position applies a windmill sense of rotation to windmill attraction force a relative side distinguished and admirable simultaneously.

The depression that can evenly distribute on the outer surface of awe, this can make more remarkable effect.This moment depression or groove are with a kind of definite regular figure but or also be distributed on the surface of awe with irregular figure.This just makes wind snarl on uneven or rough awe surface by depression or groove and forms eddy current.Therefore wind does not flow away from this awe surface.This just guarantees that windmill has good especially starting performance.

Also a wing plate can be fixed on each running shaft.Form a space whereby between the wing plate and the awe of having rotated, the wind that comes by stream forms aerodynamic pressure in this space.These wing plates are level and smooth, so wind energy successfully here flows through as far as possible.

Also can take a kind of like this structure by another favorable characteristics of the present invention, promptly awe and the wing plate pin joint in the running shaft scope interconnects.Guarantee that whereby wing plate is fixed on this running shaft, awe can swing back and forth on this axle.

Can near two end plate edges block be installed in the awe tail region in addition.Guarantee that whereby the outside swing of awe does not exceed the cylindrical profile of windmill.

Cylindrical body is installed in rotation on the running shaft that is positioned at its axis and suits.

Therefore can adopt such structure, a generator promptly is installed in cylindrical body like this, the stator of this generator is contained on the cylindrical body, and rotor is contained in the fixing rotating shaft.

Also a pump can be installed in cylindrical body.

This windmill above-mentioned can use in level or plumbness.
