Description

Megawatt-class H-type vertical axis wind power generation double triangle tower

technical field

The utility model relates to a megawatt-level H-type vertical axis wind power generation double triangle tower.

Background technique

As a kind of green renewable energy, wind energy has abundant reserves in China. According to the National Meteorological Administration, China's total wind energy reserves at a height of 10 meters above the ground are about 3.226 billion kilowatts, of which 253 million kilowatts of wind energy reserves can be developed and utilized on land. times, about 500 million kilowatts; offshore wind energy reserves that can be developed and utilized are 750 million kilowatts. In 2012, the total installed capacity of wind power in China has reached 4 million kilowatts.

According to the wind rotor and its position in the air flow, wind turbines can be divided into two categories: horizontal axis wind turbines and vertical axis wind turbines. At present, vertical axis wind turbines are gradually being valued due to the advantages of no need to face the wind, the fact that the speed-increasing gearbox and generator can be installed on the ground, and the operation and maintenance are convenient.

The wind rotors of the existing H-type vertical axis wind turbines all rotate around the same axis. Since the wind rotors of each stage are at different heights, the wind speed and torque they are subjected to are different, so that the upper and lower positions of the same rotation axis The torque difference is large, resulting in unbalanced force on the rotating shaft, which affects the working efficiency of the wind rotor. The tripod used to fix the wind rotor often adopts a single triangle structure, which cannot solve the unbalanced force on the rotating shaft. Moreover, the existing tripod structure has a single low bending rigidity, and cannot play a good stabilizing effect under the situation of different upper and lower torques of the rotating shaft.
