A vertical axis hydroelectric generator

Abstract

The invention provides a vertical axis hydroelectric generator. A tower column is arranged on a pile foundation. An impeller is arranged in water. A bearing for the impeller comprises an annular rail, an annular installing seat and multiple wheels arranged on the installing seat. A generator set comprises a hydraulic control system, a power generator and a power switching mechanism. The power switching mechanism comprises a driving disc arranged below a water platform. The driving disc surrounds a supporting column and is connected with blades. Multiple upwards-protruding ejector blocks are arranged on the edge of the top of the driving disc. The hydraulic control system comprises a hydraulic motor, a constant pressure liquid storage barrel and multiple hydraulic cylinders. Piston rods of the hydraulic cylinders are vertically downward and penetrate the water platform to correspond to the ejector blocks, and the driving disc rotates to drive the piston rods of the hydraulic cylinders to move up and down. The output ends of the hydraulic cylinders are connected with the constant pressure liquid storage barrel. The output end of the constant pressure liquid storage barrel is connected with the hydraulic motor. The hydraulic motor is in linkage with the power generator. Energy conversion is conducted through the hydraulic control system, and the energy conversion efficiency can be improved through the multiple hydraulic cylinders.

Description

technical field [0001] The invention relates to ocean current energy power generation, in particular to a device for converting ocean current energy into vertical axis mechanical rotation and then generating electricity. Background technique [0002] Ocean current energy has high energy density, cleanliness, and strong predictability, and ocean current energy does not occupy valuable land resources for power generation. 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 Chinese patent, a low-speed direct-drive hydraulic ocean current power generation device with a publication number of 103206334A, including an impeller, a quantitative hydraulic pump connected to the main shaft of the impeller, and a parallel connection with the quantitative hydraulic pump. And the variable hydraulic pump, variable hydraulic motor and generat...

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
