Vertical axis wind turbine

Abstract

A vertical axis wind turbine comprises a base and blades. A rotation shaft is arranged in the base and provided with a fixed disc and a plurality of blade sets. The blade sets are evenly distributed. Each blade set comprises supporting rods hinged to the corresponding blades. A buffering and beneficiating device is arranged at the outer end of each blade in a matched mode. A hydraulic pump is disposed on the fixed disc. An inner gear is arranged on the inner wall of the base, and a hydraulic pump gear is engaged with the inner gear. An oil outlet of the hydraulic pump is sequentially connected with a pressure adjusting device and an execution mechanism. The pressure adjusting device comprises an adjusting valve shell. The adjusting valve shell is provided with an adjusting valve oil outlet, an adjusting valve oil inlet, an oil return opening and an oil return opening adjusting device matched with the oil return opening. The adjusting valve oil outlet is communicated with the execution mechanism. The adjusting valve oil inlet is connected with the oil outlet of the hydraulic pump. The oil return opening is communicated with an oil tank of the hydraulic pump. The vertical axis wind turbine can be started and rotated at a low wind speed, operation is stable, and the operation safety of the vertical axis wind turbine is improved.

Description

Technical field [0001] The invention belongs to the field of wind generators, and particularly relates to a vertical axis wind generator. Background technique [0002] Wind power is a clean and renewable energy source, and this resource is abundant and can be used endlessly; traditional wind turbines are mostly horizontal axis, the disadvantages of horizontal axis wind turbines are: wind installation is required, wind energy utilization efficiency is unstable; operation noise Compared with horizontal-axis wind turbines, vertical-axis wind turbines have no wind direction, low operating noise, convenient installation and maintenance, and have been sought after by the industry; but vertical-axis wind turbines have low wind energy utilization efficiency and impact The use of wind energy is affected by the large impact force and these shortcomings have always restricted its development. Summary of the invention [0003] The present invention aims to provide a vertical axis wind power ...

Problems solved by technology

[0002] Wind power is clean and renewable energy, and the resource is abundant and can be used indefinitely; traditional wind turbines are mostly horizontal-axis, and the disadvantages of horizontal-axis wind turbines are: wind-facing devices are required, and the efficiency of wind energy utilization is unstable; operating noise Large, difficult to install and maintain; compared with horizontal axis wind turbines, vertical axis wind turbines have no wind direction, low operating noise, convenient installation and maintenance, and have been sought after by industry insiders; but vertical axis wind turbines have low wind energy utilization efficiency and impact The large impact force affects the utilization of wind energy. These shortcomings have always restricted its development.
