New Vertical Axis Distributed Wind Turbine

Abstract

According to the technology, the invention provides a perpendicular shaft low-wind-speed distributed wind power unit. The perpendicular shaft low-wind-speed distributed wind power unit is a practical and wind-range wind energy utilization device, can be integrated with a building and is safe in operation. The perpendicular shaft distributed wind power unit is characterized in that a structure assembly comprises a perpendicular shaft wind ball wind machine device, a ball-type potential flow cover device and a supporting device at the axial bottom of the ball-type potential flow cover device, wherein the perpendicular shaft wind ball wind machine device is arranged in the center of the ball-type potential flow cover device, the perpendicular shaft wind ball wind machine device and the ball-type potential flow cover device share the same ball center and the same perpendicular main shaft, and the external ball-type potential flow cover device is fixed. According to the main technical feature, the inner arc curved surface concave face of a blade included angle is in the head-on inflow velocity direction, and the outer arc curved surface convex face is in the backflow velocity direction to form rotating torque; meanwhile, the outer arc curved surface convex face forms the flow line curved surface in the main shaft rotating direction, the incident flow surface resistance of a blade in the wind ball rotating direction is reduced, noise is not generated, and the higher pushing resistance ratio is obtained.

Description

technical field [0001] The invention relates to a novel vertical-axis distributed wind turbine, specifically a novel vertical-axis low-wind-speed distributed wind turbine applied to the velocity potential energy of wind in the field of clean energy and new energy. Background technique [0002] Wind energy is a rare sustainable green resource that plays an important role in the survival and development of human beings. Human beings have a long history of using wind energy, and now we have entered the era of wind power. Huge propellers around the world have become synonymous with wind power. Among the many types of wind turbines, the horizontal-axis three-blade lift model dominates the wind power market, thanks to its inherent hydrodynamic geometry, which is more simple and direct in the wind field (application of kinetic energy of velocity flow) than other models High efficiency, so it has been developed rapidly. However, this model has high requirements on wind speed and di...

Problems solved by technology

At the same time, the wake of this model is diffused, which greatly increases the installation distance between wind turbines, which is also a huge waste of valuable wind farm resources.

The current wind turbines are too constrained by the natural wind speed, the timely adjustment performance is very poor, and they are completely in a passive operation state
