Synchronizing mechanism for supporting wheel in wind wheel of vertical axis wind turbine

Abstract

The invention discloses a synchronizing mechanism for a supporting wheel in a wind wheel of a vertical-axis wind turbine, and belongs to the technical field of wind turbine components. The mechanism comprises a vertical spindle, wherein two supporting wheel discs are fixedly connected to the vertical spindle, a plurality of vertical blades are connected to the outer side walls of the supporting wheel discs through a plurality of buffer connecting rod components, a plurality of air blocking openings are formed in the vertical blades, the inner walls of the air blocking openings are rotationally connected to regulation rotating shafts, buoyancy blades are fixedly connected to the outer side walls of the regulation rotating shafts, blade control motors are arranged on the buffer connecting rod components, and the output ends of the blade control motors are connected to the regulation rotating shafts through joint control components. According to the mechanism, the openings are formed in the vertical blades, the buoyancy blades capable of being controlled respectively are arranged in the openings, and a stress area of the vertical blades is changed by changing the angles of the buoyancy blades, so that when wind speeds of the upper end and the lower end are different, reasonable adjustment can be achieved, so that driving force acting on the upper and lower ends of the vertical blades are guaranteed consistent.

Description

technical field [0001] The invention relates to the technical field of wind power generator components, in particular to a synchronous mechanism for supporting wheels in a wind rotor of a vertical axis wind power generator. Background technique [0002] Wind power generation, like solar power generation, was originally developed to solve emergency power supply and power supply in remote areas, so the initial development was not very fast. In the 1920s and 1930s, the energy shortage brought about by the global economic crisis made experts from all over the world think of the feasibility of using wind power as a supplementary energy source. Compared with solar energy, wind power has obvious cost advantages. How to integrate wind power and buildings, and install small wind turbines around buildings without affecting people's quality of life has become the focus of research in some European and American countries. . In terms of classification, vertical axis wind power generati...

Problems solved by technology

[0003]In vertical wind power generation, the blades are vertically distributed around the support wheel, which makes the height difference between the top and bottom of the blades, and in the natural environment, the There is a difference in the wind speed generated, which makes the upper and lower ends of the blade act differently on the blade when the wind is applied, which causes the blade itself to generate torque. When the wind is strong enough, the torque will be significantly amplified, and the existence of torque will It affects the service life of the blades, and the gravity generated by the blades will always act on the support wheels during the rotation process, which will cause friction to the rotation of the support wheels and affect the synchronous rotation of the support wheels. For this reason, a vertical axis wind turbine is proposed Synchronization mechanism of support wheel in wind wheel
