Description

Technical Field

[0001] The utility model relates to the technical field of clean energy utilization, in particular to a truss-type large-blade wind-solar power generation device. Background Art

[0002] As the most important and mature renewable clean energy, wind energy has the advantages of rich reserves, wide distribution, and no pollution. Wind turbines convert the kinetic energy of wind into mechanical energy to drive AC induction generators to generate electricity. Modern wind turbines can be divided into horizontal axis wind turbines and vertical axis wind turbines. Horizontal axis wind turbines with two or three blades are more common. Due to the limitations of the central vertical axis and the suspended blade bracket, vertical axis wind turbines generally have a small output power and are difficult to scale up, or the production cost of high-power industrialized vertical axis wind turbines is too high; low power generation efficiency is also a major obstacle to the marketization of vertical axis wind turbines. Variable pitch and yaw mechanisms also bring many hidden dangers to horizontal axis wind turbines; high-speed ratio speed increasers not only affect the efficiency of wind energy conversion, but also easily cause wear and damage; the extra-long blades, extra-high towers, and extra-heavy speed increasers of large horizontal axis wind turbines also bring great difficulties to installation and maintenance; the cost of power generation also needs to be further reduced. Noise is still a common problem of wind turbines.

The frame is made of aluminum alloy profiles, the structure is light, and the assembly workload is large. Utility Model Content
