Multi-rotor wind generating system capable of automatically facing wind

Abstract

The invention discloses a multi-rotor wind generating system capable of automatically facing wind. The multi-rotor wind generating system comprises a tower, wind turbines, an A slewing bearing 2, a B slewing bearing 3, a framework 4, beams 5 and tail vanes 8; the A slewing bearing is arranged on the top of the tower; the B slewing bearing is arranged in the middle of the tower; inner rings of theA slewing bearing and the B slewing bearing are fixed on the tower; outer rings of the A slewing bearing and the B slewing bearing are connected with the framework; one end of each beam is connected with the framework; the wind turbines are fixedly connected with the beams; each wind turbine comprises a wind wheel 6 and a cabin 7; 2 to 100 wind turbines are arranged; the lengths of the beams on two sides of the framework are different; the longer beams are provided with more wind turbines than the shorter beams; the tail vanes are connected with the framework, the beams or / and cabins through pin rolls. The multi-rotor wind generating system capable of automatically facing wind has the advantages that: blades have long service life, the occupied area is small, installation and maintenance cost is low, the reliability is high, the application range is wide, a slewing bearing or a rotary driving device in the cabin is eliminated, and the automatic wind facing and yawing are realized.

Description

technical field [0001] The invention belongs to the field of wind energy utilization, and relates to a multi-rotor wind power generation system capable of automatically facing the wind. Background technique [0002] With the global energy crisis and global environmental pollution intensifying, many countries are paying more attention to the research, development and utilization of clean and renewable energy. The Global Wind Energy Council pointed out that compared with other renewable energy technologies, wind power technology is more mature, its efficiency is higher, the industry has the best prospect, and its development and utilization growth rate is much higher than that of conventional energy. One of the fastest renewable energy technologies. [0003] The wind rotor is the core component that converts wind energy into mechanical energy, so the performance of the blade determines the performance of the wind turbine, and the safe and stable operation of the blade within ...
