Multi-rotor wind generating system with connecting rods

Abstract

The invention discloses a multi-rotor wind generating system with connecting rods, which comprises a tower 1, wind turbines, two slewing bearings 2, a framework 4, beams 5 and the connecting rods 8. A rotary driving device A is arranged on the top of the tower; a rotary driving device B is arranged in the middle of the tower; inner rings of the slewing bearings of the rotary driving device A and the rotary driving device B are fixed on the tower; the framework is fixedly connected to the outer rings of the slewing bearings of the rotary driving device A and the rotary driving device B; one end of each beam is connected with the framework; one end of each connecting rod is connected with the middle part of each beam, and the other end of each connecting rod is connected with the framework; wind turbines are fixedly connected with the beams; each wind turbine comprises a wind wheel 6 and a cabin 7; and the power of each wind turbine is 0.5-500kW. The multi-rotor wind generating system 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, the bearings bear small force, and the beams bear small force.

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 connecting 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 decreases with the increase of power, the total cost will increase on the contrary considering the maintenance and other costs in the later period.

On the other hand, the length of blades of giant wind turbines will reach 60-70m, and land transportation and installation are extremely difficult. The capacity of cranes used for installation will exceed 1200-1400t. Many areas do not have this condition, thus limiting the use of giant wind turbines
