Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generators, in particular to a horizontal spiral-wing wind turbine generator. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Among all types of wind turbines, vertical-axis wind turbines are more common. Traditional vertical-axis wind turbines mainly include Q-type, spiral-type, H-type and other styles. The above types are also widely circulated on the market. Regardless of how the installed capacity changes, these vertical-axis wind turbines have their own defects. For example, Q-type and spiral-type wind turbines are unable to capture more wind energy due to the limitation of their own wind rotor diameter. When a satisfactory wind speed is reached, the existing wind energy cannot be fully utilized, resulting in poor power generation efficiency. H-type wind turbines generally have the problem of high starting wind speed requirements. At low wind speeds, the cut-in wind speed cannot be reached, and the wind turbine cannot generate electricity normally.

[0003] In the wind turbines in the prior art, the blades are large, the starting wind speed is high, and the installation is inconvenient. In addition, the shape of the blades is fixed, and it is impossible to effectively utilize the wind in all directions and capture wind energy at high altitudes. At low wind speeds, there is still the defect of insufficient overall power generation efficiency, especially on the tops of buildings such as office buildings, factories, and residences. Due to the limited bearing capacity, general wind turbines cannot be installed on the tops of buildings. For this reason, we propose a horizontal spiral wind blade wind turbine.
