Multi-rotor wind generating system with suspenders

Abstract

The invention discloses a multi-rotor wind generating system with suspenders. The multi-rotor wind generating system comprises a lower tower 1, a rotary driving device 3, wind turbines, an upper tower 2, ropes and/or connecting rods 8, beams 6, a cabin frame 7 and the suspenders 9, wherein the rotary driving device is arranged between the upper tower and the lower tower; two sides of the upper tower are connected with one end of each beam; the outer end and the middle part of the uppermost beam are connected with the top of the upper tower through the ropes and/or the connecting rods; outer ends of adjacent beams are connected through the ropes and/or the connecting rods; middle parts of the adjacent beams are connected through the ropes and/or the connecting rods; the upper ends of the suspenders are fixedly connected with the lowermost beam; the cabin frame is arranged on the upper tower; the wind turbines are arranged on the upper tower; and the wind turbines are fixedly connected with the top of the upper tower, the beams, the cabin frame or/and the lower ends of the suspenders. The multi-rotor wind generating system has the advantages of long service life, small floor area, low installation and maintenance cost, high reliability, wide application range, no rotary driving device in a cabin, and low bearing overturning moment.

Description

technical field [0001] The invention belongs to the field of wind energy utilization and relates to a multi-rotor wind power generation system with suspension rods. 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 the design life is ve...

Problems solved by technology

Once a problem occurs, the wind farm will cause economic losses due to downtime and power outages, plus the cost of maintenance, hoisting and replacement parts, over-limit transportation, repeated installation, etc. In addition, most of the wind turbines are installed in remote or inaccessible areas, so it is difficult to hoist and disassemble Big, huge price paid in the end

Therefore, although the manufacturing cost of wind turbines decr
