Abstract
The utility model relates to a windmill and provides an improved oscillating-wing windmill which is provided with a substrate, a bracket and oscillating wings, wherein the central rotating shaft of the bracket is arranged on the substrate, and one side of the oscillating wing is connected with the bracket by a hinge. The bracket is better set as a triangular star-shaped bracket, and accordingly, the number of the oscillating wings is 3; and one sides of the three oscillating wings are respectively connected with the triangular star-shaped bracket by hinges. Compared with the current common windmill with vertical shafts, conventional fan blades are designed into the oscillating wings capable of automatically increasing or reducing the windage area, and the oscillating wings can automatically increase the windage area when doing action at the windward side so as to capture more power; and when running at the leeward side, the oscillating wings can automatically reduce the windage area, thus reducing power loss.
Description
Technical field
The utility model relates to a kind of windmill, especially relates to a kind of swing wing type windmill.
Background technique
Existing common vertical axis windmill generally is provided with fixedly flabellum, and its shortcoming is that the difference of the wind-exposuring area of windmill and leeward area is less, so that the wind energy that the flabellum that facings the wind is caught has a large portion to be consumed by leeward flabellum.
Notification number provides a kind of cartridge type windmill with the concentric cylindrical body of windmill shaft that has for the patent of invention of CN1036248.This cylindrical body respectively has a circular end plate at its two ends, awe is processed into crooked streamlined external form.These awes are parallel on the running shaft of windmill shaft near being installed in the edge that is positioned at two end plates, and its angle of swing is restricted.Therefore can adopt such structure, on the windmill circumference, the awe of 4 crooked streamline sections and awe are set at least and be installed on the running shaft, in the edge of end plate and the zone between the cylindrical body, rotate with the head of its front with the circumference spacing that equates.
Publication number provides a kind of leaf type windmill for the application for a patent for invention of CN85103919, the wind wheel of this wind energy conversion system is made up of blade, petiole, leaf bar. because blade is mobilizable with respect to the leaf bar, thereby realized the automatic wind facing of wind energy conversion system, the oneself starts, automatically adjusting vane angle, and the control that can exceed the speed limit automatically.Because circular arc vane is one with lift and resistance remittance, produce making a concerted effort of promotion wind wheel rotation simultaneously, improved efficient.
Summary of the invention
The purpose of this utility model is to provide a kind of improved pendulum wing windmill.
The utility model is provided with pedestal, support and the pendulum wing, and the centre rotational axis of support is located on the pedestal, and a side of the pendulum wing is connected with support by hinge.
Described support preferably is made as 3 jiaos of star-shaped supports, and the wing is corresponding establishes 3 for pendulum, and sides of 3 pendulum wings are connected with 3 jiaos of star-shaped supports by hinge respectively.
The utility model is the improvement to common vertical axis windmill, because the pendulum wing of the present utility model links to each other with support by hinge, support links to each other with pedestal, when wind when any substantially horizontal blows to windmill, have at least a pendulum wing to facing the wind and stretch and the rotation of promotion windmill, meanwhile, leeward pendulum wing flexion under wind action reduces the resistance that windmill rotates.The pendulum wing and support can be done to rotate at any angle under the effect of external force around the running shaft of support, and the pendulum wing can be made flexion or extending movement around the central shaft swing of hinge under the effect of external force.
Compare with existing common vertical axis windmill, the utility model is designed to increase and decrease automatically the pendulum wing of blowing area with the flabellum of routine, and all pendulum wings increase blowing area automatically when doing work down with the wind, to catch more power; When leeward operation, then automatically blowing area is reduced, thereby reduce kinetic equation loss.
