Abstract
The utility model relates to a speed-limiting spring device for a vertical spindle dual-diameter wind motor. The speed-limiting spring device for a vertical spindle dual-diameter wind motor adopts a pressure spring whose pressure is roughly equal to centrifugal deflection force generated by a blade in operation, and flexing dimension is roughly equal to the rotary distance of the front edge of the blade. A flange with a pistil rod is sheathed on the inner diameter of the pressure spring. A flange outer ring is drilled with holes whose numbers are the same as blade numbers and diameters are equal to steel wire diameters, and the holes are evenly distributed. Steel wires are fixed on the flange holes, and the lower ends of the steel wires downward thread out the flange holes on the middle spindle of a wind wheel and are connected with blades via a guide pulley. A spring tube is covered on the outer diameter of the pressure spring. The pressure spring in the spring tube can not be corroded by rain water and salt fogs. Thus, the service life of the vertical spindle dual-diameter wind motor is raised.
Description
The utility model is a kind of return spring device of the centrifugal angle of vertical shaft dual-diameter pneumatic equipment blades made.
Vertical shaft dual-diameter wind energy conversion system is for speed limit, and speed governing adopts major and minor leaf interlock to realize with the adjustment of the phase counterblast angle of attack.When rotating speed was high, accessory lobes were under centrifugal action, and leading edge drives the main lobe leading edge to extrinsic deflection and closes shape to the intrinsic deflection double leaf, and wind speed round reduces; When rotating speed hanged down to rating value, the elastic force after the return spring compression just will retract to the accessory lobes of extrinsic deflection, and double leaf is made open shape, thereby made the wind speed round raising down with the wind with the air-flow angle of attack of the best.
My the blade return spring device of institute's patent (F03D3/00 85105331.9) " vertical axis windmill " is the centrifugal pendulum spring assembly, since complex structure sealing difficulty, the spring easy-to-rust.
The utility model provides a kind of pressure spring device, and its effect also can make return behind the blade angle.This stage clip is contained in the bourdon tube of sealing.
The utility model is achieved like this: the centrifugal deflecting force of selecting pressure and blade generation in service for use about equally, flexible size and blade inlet edge rotation distance be about equally pressure spring (4) also, on the stage clip internal diameter, adorn the flange (3) of a band stamen rod, the flange outer ring is drilled with the hole of identical with the wind wheel blade number and uniform diameter and wire rope (5) equal diameters, the wire rope upper end is pierced into the Kong Zhongzha head and is fixed, and the lower end passes downwards by leading block (7) and accessory lobes from the corresponding hole of wind wheel upper flange (6) and is connected and fixed.Internal diameter and the bourdon tube (2) that stamen rod flange outer diameter equates substantially on the stage clip outer cover can slide up and down the excellent flange of stamen in bourdon tube.On the bourdon tube top, a roof pressure screw rod (1) is set adjusts the spring power.
The utility model is because structure is easy than the centrifugal pendulum extension spring, and it is more suitable to be used on the vertical shaft dual-diameter wind energy conversion system, because stage clip is owing to there is the effect of bourdon tube, and unstability not, simultaneously can guarantee that spring is not subjected to rainwater, salt spray corrosion, thereby wind wheel structure is simplified, improve working life.
Claims (1)
1, vertical shaft dual-diameter wind energy conversion system speed limit spring assembly is made up of a pressure spring (4), stamen rod flange (3), bourdon tube (2), roof pressure screw rod (1), wire rope (5) and leading block (7) etc., and its feature is as follows:
Be equipped with on pressure spring (4) internal diameter on stamen rod flange (3), the external diameter and be covered with bourdon tube (2);
