Problems solved by technology

[0004] At present, most wind turbines use tall towers and large blades, relying on the wind force and the slope of the windward side of the blades to generate thrust and drive the generator to rotate. This type of wind turbine has a complex structure and low wind energy utilization. Generator: Rotating blades and the different wind surface of the blades generate certain resistance, resulting in a decrease in the utilization rate of wind energy and low efficiency. However, the existing wind turbines may not be able to drive the blades due to excessive load when the natural wind force is small. rotation, resulting in the inability to make full use of wind energy

Abstract

The invention discloses an adjustable type vertical-axis wind turbine comprising a first base frame and a second base frame. Vertical racks are fixedly connected between the first base frame and the second base frame. The bottom side of the middle of the second base frame is rotationally connected with a rotating shaft. The side wall of the rotating shaft is fixedly connected with three groups ofconnection rods. Rotating rods are rotationally connected between the every two adjacent groups of connection rods which are opposite up and down. Blades are fixedly connected to the rotating rods. The bottom end of the rotating shaft extends into the first base frame in a penetrating manner to be fixedly connected with a drive toothed plate. An installation frame is fixedly installed in an innercavity of the first base frame. The installation frame is provided with 12 groups of sliding slots which are distributed in central symmetry about the center of the installation frame. Generators aremovably connected into the inner walls of the sliding slots. The tops of the generators are fixedly connected with driven gears. The driven gears are all meshed with the drive toothed plate. By the adoption of the adjustable type vertical-axis wind turbine, the number of driven gears which are rotationally connected with the toothed plate in a clamped manner is adjusted according to the wind forceof natural wind, so that the efficiency of converting wind energy into electric energy can be improved.

Description

Technical field: [0001] The invention relates to the field of wind power generators, in particular to an adjustable vertical axis wind power generator. Background technique: [0002] Wind turbine is a device that converts wind energy into electrical energy. It is mainly composed of blades, generators, mechanical parts and electrical parts. According to the different rotating shafts, wind turbines are mainly divided into horizontal axis wind turbines and vertical axis wind turbines. At present, horizontal axis wind turbines occupy the mainstream position in the market. For many centuries, wind turbines, like hydraulic machinery, have replaced human and animal power as a power source, and have played an important role in the development of productivity. The extensive application of modern electromechanical power and the discovery of Middle East oil fields in the 1950s slowed down the development of wind turbines. [0003] In the early 1970s, due to the "oil crisis", there was a pro...
