AI Technical Summary
Existing wind turbine rotor systems lack efficient mechanisms for automatic and manual adjustment of blade angles to optimize energy capture based on wind direction and speed, leading to suboptimal performance.
A wind rotor system with two welded nuts and a loose nut on a threaded rod, combined with a spring and elastic cord connected to a movable weight, allows for both manual and automatic adjustment of blade angles by balancing centrifugal force and spring tension to regulate rotational speed.
Enables precise control of blade angles for enhanced energy capture by adapting to varying wind conditions, improving efficiency and performance.

Abstract
Description
[0001] Two nuts (mü), spaced apart and welded to a threaded rod, are welded together onto a base plate (grpl). A third nut (Imü) remains loose. The blade is then welded to the threaded rod behind this third nut. For manual adjustment, after selecting the angle relative to the wind direction, the loose nut (Imü) is tightened against the adjacent one. This rigidly connects the blade to the rotor. For automatic adjustment, a spring is attached, acting on one edge of the blade. An elastic cord (sel) is clamped to the opposite edge and connected to a weight (mg), which is movable and can slide in the radial direction. The rotational speed is regulated once these forces (centrifugal force and spring tension) are balanced. Per blade: 1 unit of weight 1 Suspension 1 screw 1 washer 1 piece of tensioning cable
Claims
[1] Manual adjustment. For manual adjustment, after selecting the angle to the wind direction, the loose nut is tightened firmly against the following one. This holds the wind vane rigidly on the base plate. [2] Automatic Adjustment For automatic adjustment, attach a spring that touches the top of the wind vane and whose other end is firmly attached to the base plate. On the opposite side of the wind vane, connect it to the weight with a tensioning cable. The rotational speed will adjust itself once the centrifugal force has been balanced by the tension of the spring.
