Abstract

The utility model discloses a windmill which can change wind energy into electric energy or mechanical energy, comprising a wheel disc, a gear ring installed on the wheel disc and a power take-off system comprising a gear wheel meshed with the gear ring, a rotating shaft, a belt and a motor. The wheel disk is provided with a short shaft which is provided with a moving blade, and a spring is arranged between the moving blade and the wheel disk. The outer edge of the wheel disc is provided with a fixing blade. The utility model has the advantages of orientating installation and large output power.

Description

Wind wheel

The utility model belongs to wind motor, particularly a kind of windmill that has moving vane.

Windmill is a kind of traditional device that utilizes wind energy, and many types are arranged.According to the arrangement of wheel disc, can divide to be arranged horizontally and to be arranged vertically two kinds.The wheel disc of horizontal arrangement can not be limited by wind direction, but wind utilize area little, output power is also little.Be arranged vertically, wind utilize area big, output power is big, but will be limited by wind direction.Yet in any shape, all be on wheel disc, to arrange some blades, wheel disc rotated, outwards export electric energy or mechanical energy by output mechanism then, so the arrangement of blade just seems very important by the wind blade.

The purpose of this utility model is to provide a kind of not wind-engaging to influence, the directed installation, and wheel disc is arranged vertically, the windmill that output power is big.

The utility model is made up of support, wheel disc and a cover power output system.Minor axis in correspondence with each other is installed on wheel disc, is set with sleeve pipe on the minor axis, be connected with moving vane on the sleeve pipe; End at moving vane is connected with a spring, and the other end of spring is fixed on the wheel disc; In the wheel disc outer rim stator blade is installed also.After the wind moving vane rotates wheel disc, just drive and the wheel disc meshed gears, outwards export electric energy or mechanical energy by power output system then.

Advantage of the present utility model is that wind-engaging is not to influence, and output power is big.

Fig. 2 is a plan view of the present utility model;

Fig. 3 is a left view of the present utility model;

Describe in detail below in conjunction with accompanying drawing.The utility model has a support 1 by the shaped steel welding fabrication, by bolt two bearing supports 11 is arranged on the support 1, by axle 14 wheel disc 8 is installed on bearing support 11, is welded with mutual correspondence on the said wheel disc 8, is no less than 3 pairs minor axis 12 and 13.On corresponding mutually

minor axis

12 and 13, be set with the sleeve pipe 16 that can rotate around it, be welded with moving vane 15 on the sleeve pipe 16, said moving vane 15 can be that metallic material and sleeve pipe 16 weld together, and also can be that nonmetallic material such as plank, plastics, canvas and sleeve pipe 16 are sewed together.Also sleeve pipe 16 and moving vane 15 can be made one.Said sleeve pipe 16 is divided into two-part with the area of blade 15, and the ratio of its left and right area is 1:2, and the ratio of weight is 1:1.End at moving vane 15 is equipped with spring 17, and the other end of spring 17 is welded on the wheel disc 8.On wheel disc 8, also be welded with stator blade 6 more than three.Be welded with a gear ring 7 in the wheel disc outer rim.On support 1, also a bearing support 2 and generator 4 are arranged, a rotating shaft 18 is installed in bearing support 2, a gear 19 that is meshed with gear ring 7 on the wheel disc 8 is installed at an end of rotating shaft 18 with bolt.The input end of the axle of said rotating shaft 18 the other ends and generator 4 links together by belt 3.Output terminal in 4 in generator is set with a decelerating ring 22, and decelerating ring 22 is welded with a sheet metal 21 by connecting rod 20.

The wind direction that the direction of this windmill plan view is often blown over against this locality, when wind came, moving vane 15 rotated owing to wind-force centers on

minor axis

12 and 13, because the pulling force of spring 17, moving vane 15 can rotate in 0-180 degree scope.Like this, wherein the part of wind-force can be decomposed into the power that wheel disc is rotated and forces wheel disc 8 to rotate, and wheel disc 8 rotates by driving rotating shafts 18 with its meshed gears 19, by belt 3 and generator 4 wind energy is transformed into electric energy at last.When wind-force is big, blows sheet metal 21 and make connecting rod 20 twistings and make the decelerating ring 22 and the output shaft of generator 4 produce friction, thereby reach the purpose of deceleration.

Claims

1, a kind of windmill, comprise support 1, wheel disc 8, be installed in the gear ring 7 on the wheel disc 8, and by the power output system of forming with gear ring 7 meshed gears 19 and rotating shaft 18, belt 3 and generator 4, it is characterized in that: minor axis 12 and 13 are installed on wheel disc 8, be set with sleeve pipe 16 on the minor axis 12 and 13, moving vane 15 is installed on the sleeve pipe 16, at an end of moving vane 15 spring 17 is installed, the other end of spring 17 is installed on the wheel disc 8; Outer rim at wheel disc 8 also is equipped with stator blade 6.

2, according to the said directed windmill of claim 1, it is characterized in that: the area of said moving vane 15 is divided into two-part by sleeve pipe 16, and the ratio of its left and right area is 1:2, and the ratio of weight is 1:1.
