Abstract

The invention discloses a center fixed-supporting vertical axis wind turbine, comprising a ground base, a central axis, a blade and a generator, and further comprising at least two positioning grooves, at least two positioning racks, an interlayer torque transmission mechanism and a small bearing or a pulley, wherein the central axis is vertically and fixedly mounted on the ground base, the positioning grooves are fixedly mounted at the lower part and the middle-upper part of the central axis, respectively, the positioning racks are mounted on corresponding positioning grooves respectively via the small bearing or the pulley, the interlayer torque transmission mechanism is fixedly connected between the positioning racks, the blade is mounted on the positioning rack at the middle-upper part of the central axis via a blade frame, a rotor of the generator is mounted on the positioning rack at the lower part of the central axis via a bracket, and a stator of the generator and a casing are sleeved on the rotor of the generator and are fixedly mounted on the ground base. The center fixed-supporting vertical axis wind turbine has the advantages of stable operation, small fluctuation, strong anti-typhoon performance, high utilization rate of wind power, simple structure, low cost, long service life, convenient installation and maintenance and the like, and is better suitable for being installed and used at locations where the wind direction is changeable and the wind changes at any time.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a wind power generator with simple and reliable structure, stable operation, convenient use and maintenance, low cost, high efficiency, long service life, wide effective wind speed range, multi-layer blades, and fixed support of the central shaft , belonging to the field of wind power generation. Background technique [0002] Wind energy is the cheapest, most convenient, and cleanest renewable green energy used by human beings. Compared with traditional energy sources, wind power generation does not rely on fossil energy, has no fuel price risks, stable power generation costs, and no carbon emissions, etc. environmental cost. Therefore, wind power has gradually become an important part of the sustainable development strategy of many countries and has developed rapidly. Wind turbines are the main equipment for utilizing wind energy, which can be divided into two types: horizontal axis w...
