A Vertical Axis Wind/Hydroelectric Generator

Abstract

The invention discloses a vertical-shaft wind-hydraulic electric generating device which comprises a tower column, a wind energy conversion unit, a hydraulic energy conversion unit, a hydraulic control system and an electric generator. The hydraulic energy conversion unit comprises a first impeller and a first driving disc which surround the tower column. The upper end and the lower end of the first impeller are pivoted to the exterior of a first supporting column through bearings respectively. The upper end of the first impeller is connected with the first driving disc. The edge of the top of the first driving disc is provided with a plurality of first top blocks protruding upwards. The first driving disc drives a hydraulic cylinder through the first top blocks. The output end of the hydraulic cylinder is connected with a constant-pressure liquid storage tank. The output end of the constant-pressure liquid storage tank is connected with a hydraulic motor. The hydraulic motor is in linkage with the electric generator. The hydraulic control system is adopted for energy conversion, and multiple hydraulic cylinders can be arranged to improve energy conversion efficiency.

Description

technical field [0001] The invention relates to the field of wind energy and ocean current energy power generation, in particular to a vertical axis wind / hydro power generation device. Background technique [0002] Existing renewable and pollution-free power generation mainly relies on wind power generation. Due to many restrictions on wind power generation, it has been difficult to meet people's needs. Ocean current energy has high energy density, cleanliness and strong predictability, and ocean current energy power generation does not occupy valuable land resources. Therefore, the development and utilization of ocean current energy has far-reaching significance. At present, there are also many devices that use ocean current energy to generate electricity, such as a low-speed direct-drive hydraulic ocean current power generation device with Chinese Patent Publication No. 103206334A, including an impeller, a quantitative hydraulic pump connected to the main shaft of the imp...

AI Technical Summary

Problems solved by technology

At present, the device that utilizes ocean current energy to generate electricity generally converts energy for the first time through the wind wheel on the horizontal axis, then drives the hydraulic pump through the wind wheel for the second energy conversion, and finally uses the hydraulic pump to drive the generator for the third energy conversion. Conversion; because this type of ocean current energy generating device uses a horizontal axis wind rotor, each wind rotor can only drive one hydraulic pump, and each hydraulic pump can only drive one generator, resulting in the power generation of this type of generating device The efficiency is low, and the huge energy of ocean current energy has not been utilized to the maximum extent

From the field of power generation, this type of ocean current power generation device is only an ideal device for people, and has no commercial value, because the price of the electricity it generates is already higher than the current price of wind power generation
