Wind generator

Abstract

A wind generator has a post, a rail mounted on the post and a blade assembly mounted rotatably on a top of the post. The blade assembly includes multiple blades radially formed around a base. Each blade has multiple vents, a slat and multiple relief valves. The slat is controllable mounted to open or close the vents, so as to adjust a force of wind applied to the blades. The relief valves are mounted pivotally to selectively cover valve holes formed through the blades to prevent the wind resistance force applied to the blades. Therefore, the wind generator can work in both turbulent and with a low wind force without breaking.

1 . A wind generator comprising
 a post having a top and at least two support bars perpendicularly attached diametrically near the top of the post;   a rail being annular and being mounted on the support bars of the post;   a blade assembly being mounted rotatably on the top of the post, having
 a base being an open container and having a bottom opening being rotatably mounted around the top of the post and having
 an inner surface; and 
 multiple inner teeth formed around the inner surface of the bottom opening; 
 
 a bearing being mounted in the bottom opening of the base and on the top of the post to facilitate the rotation of the base; and 
 multiple blades radially protruding from the base at an angle and each blade having
 a control wing having
 a distal end; 
 a luff edge 
 a luff surface; 
 a leech surface; 
 multiple vents being formed through the control wing; and 
 multiple slats being mounted pivotably on the luff surface, respectively corresponding to and controllably covering the vents, and each slat having a leech surface; and 
 a plurality of valve holes formed through the slat; 
 
 a fixed wing mounted along the luff edge of the control wing at an angle and having
 a distal end; 
 a luff surface; 
 a leech surface; 
 a leech edge; and 
 a plurality of valve holes being separately formed through the fixed wing; and 
 
 multiple relief valves being mounted pivotally on the leech surfaces of the slats and the fixed wing, and corresponding to and selective cover the valve holes of the slats and the fixed wing; 
 
   a stay assembly comprising
 multiple struts being mounted securely to the top of the base to form an apex; and 
 multiple windlasses being mounted securely in the apex of the struts and corresponding respectively to the blades of the blade assembly, and 
 each windlass having a string connected to the distal end of the control wing of the corresponding blade and controllably pull the corresponding blade; and 
   a generator assembly comprising
 a translator being mounted securely on the post near the top of the post and having a rotatable gear wheel engaging with the inner teeth of the bottom opening of the base and rotating simultaneously with the blade assembly to retrieve kinetic energy from wind; 
 a generator being mounted securely on the post and being capable of converting the kinetic energy to electricity; and 
 at least one transmission pipe connecting the translator to the generator and transmitting the kinetic energy from the translator to the generator for conversion. 
   
     
     
         2 . The wind generator as claimed in  claim 1 , wherein the fixed wing of each blade further has multiple telescopic struts being pivotably mounted on the leech surface of the fixed wing and corresponding to the slats respectively, and each telescopic strut having a shaft connected to a corresponding slat and controllably opening or closing the corresponding slat. 
     
     
         3 . The wind generator as claimed in  claim 2 , wherein the fixed wing of each blade further has
 a wheel bracket being mounted securely on the leech edge near the distal end of the fixed wing and corresponding to the rail; and   a wheel being mounted rotatably in the wheel bracket to facilitate rotation of and stabilize the blade assembly.   
     
     
         4 . The wind generator as claimed in  claim 3 , wherein each blade further has a load equalizer comprising
 a sensor being mounted in the wheel bracket of the blade and detecting a load on the wheel of the blade;   a track being mounted securely on the leech surface of the fixed wing of the blade;   a weight being mounted slidably on the track; and   a threaded rod being rotatably mounted on the track and through the weight, and being controlled by the sensor to rotate and thereby adjust the position of the weight on the track.   
     
     
         5 . The wind generator as claimed in  claim 1  further has an accelerating motor being mounted securely near the top of the post and having an active gear engaging with the inner teeth of the bottom opening of the base to assist the rotation of the blade assembly. 
     
     
         6 . The wind generator as claimed in  claim 1 , wherein the post is tubular. 
     
     
         7 . The wind generator as claimed in  claim 1 , wherein the base is cylindrical. 
     
     
         8 . The wind generator as claimed in  claim 1 , wherein the blade assembly comprises four blades.
