Wind (water) power generator stressed in forward direction

Abstract

The invention relates to the technical field of wind (water) power generation structures, in particular to a wind (water) power generator stressed in the forward direction. The wind (water) power generator comprises a generator spindle. The two ends of the spindle are provided with supporting plates which can rotate integrally with the two ends of the spindle. A plurality of blades are arranged between the two supporting plates. Sub spindles are arranged at the two ends of each blade. The supporting plates are provided with a plurality of matching holes which are in one-to-one correspondence with the blades. The sub spindles penetrate into the corresponding matching holes in the supporting plates. The states of the blades can be switched in the wind wheel rotating process, the blades can only achieve revolution on the rear half of the circumference (namely at the angle of 190-350 degrees) to generate thrust so that an acting area can be formed, the blades can only be rotated automatically on the front half of the circumference (namely at the angle of 10-170 degrees) so that a non-acting area can be formed, the spindle can be rotated under the resultant action to act, and the distance between the blades and the spindle and the sizes of the blades and the spindle can be changed so that the power and torque can be improved. The effective surface area of the blades is larger than that of a traditional impeller, practicability is greatly improved, manufacturing difficulty and production cost are lowered, and the range of the application field of the generator is widened.

Description

technical field [0001] The invention relates to the technical field of wind (water) power generation structures, in particular to a wind (water) power generator with positive force. Background technique [0002] The main working principle of the existing wind or water power generation is that external force (water or wind) pushes the blades of a rotating impeller to rotate to generate electricity. Because the surface of the blade must have an included angle when it is stressed and the external force, That is to say, the surface of the blade must be made into an inclined plane to convert the external force in the vertical direction into the rotational force in the horizontal direction. Because the angle between the vertical force and the horizontal force is 90°, the best angle to convert the vertical force into the horizontal force is 45°, indicating that only 1 / 2 of the vertical force can be converted into a horizontal force, that is, only half of the force does useful work,...

Problems solved by technology

[0002] The main working principle of existing wind power or hydroelectric power generation is that external force (water power or wind power) pushes the blade of a rotating impeller to make it rotate to generate electricity. Since the surface of the blade must have an included angle with the external force when it is stressed, That is, the surface of the blade must be made into a slope to convert the external force in the vertical direction into the rotational force in the horizontal direction. Because the angle between the vertical force and the horizontal force is 90°, the best angle to convert the vertical force into a horizontal force is 45°, indicating that only 1 / 2 of the vertical force can be converted into horizontal force, that is, only half of the force has done useful work, which means that half of the limited resources that people have captured are wasted, due to design, structure, Influenced by factors such as production, more than that is wasted, not only that, but also use this included angle to achieve rotation. In order to obtain greater thrust, designers have to design the blades very long (the blades of wind turbines Already 8 meters to 15 meters or longer), while increasing the size and weight, it also limits the speed, increases the difficulty of production, complicates the generator, and ultimately leads to increased costs. Defects due to angles, The useful work is reduced, making the generator: high, large, heavy, complex structure and high cost, but the efficiency is not high, and the final result limits the development and application of hydraulic and wind power
