Abstract

The invention discloses a super power generating windmill, innovatively designs a circular rail bearing Y-shaped compound blade device and a hydraulic energy collecting or barometric energy collecting multi-unit power generating system, which can efficiently use wind energy in a large scale, and has the following advantages: circular rail bearing Y-shaped compound blades enable wind collecting sweeping diameter to reach more than 3000 meters; the design of bidirectional contrarotating Y-shaped compound blades enables the blade density ratio of the windmill to reach 100 percent; the design that single blades automatically rotates and revolves with the combination of compound blades through facing wind enables that when a work speed is reached, blade surfaces are adjusted to keep optimal wind receiving angles, when the wind speed is overhigh, high layer single blades are adjusted layer by layer so as to allow low layer blades to work and receive wind through smallest areas, the highest speed of the blades of the windmill do not excess the wind speed, and the highest tip speed ratio is 1, so that the power generating windmill can work in strong wind; the hydraulic energy collecting or barometric energy collecting multi-unit power generating system is distributed on the ground, so that the mounting and the maintaining are convenient, the construction cost is low, the installed capacity is high, and the installed capacity of a generator set can reach more than millions kilowatt.

Problems solved by technology

[0002] In the past, windmills for power generation were single-tower windmills with small power generation and low power generation efficiency. The main technical problems were as follows: First, expanding the diameter of the wind rotor in proportion can generate more power, which also brought about a significant increase in the weight of the wind rotor and generator. Increased bearing loads lead to fatigue and reduced service life, so the diameter of the largest existing wind turbine blades will not exceed 200 meters; the second is to increase the solidity ratio of windmill blades, so that the same swept area can obtain a larger wind capture area It can generate more electricity; while the solidity ratio of traditional windmill blades is between 5% and 20%, it is a waste of wind resources; the third is to increase the rated wind speed and increase the most effective - full-load power generation time, while the cut-off wind speed of traditional windmills is generally It is 25m / s and the magnitude of the wind energy is proportional to the third power of the wind speed. That is to say, we only use the energy of the lower wind speed, and have to give up the considerable wind energy when the wind is high; The Y-shaped compound blade multi-unit energy-collecting windmill can overcome the above-mentioned technical problems.
