Power generating method utilizing ocean current energy

Abstract

The invention discloses a power generating method utilizing ocean current energy. A tower column is established on sea to serve as a pivoted shaft of an impeller. The impeller is immersed in water. Blades included by the impeller are lifting blades. The impeller is pushed to rotate through the ocean current. The impeller rotates to drive a drive disc embracing the tower column to rotate. The drive disc ejects a piston rod of a hydraulic cylinder through ejector blocks which protrude upwards and are arranged on the edge of the top of the drive disc, and accordingly the piston rod of the hydraulic cylinder is driven to do telescopic movement. The hydraulic cylinder pushes hydraulic oil to a constant-pressure liquid storage barrel for storage. When power generation is needed, the hydraulic oil in the constant-pressure liquid storage barrel is released to drive a hydraulic motor to rotate. The hydraulic motor drives a generator to synchronously rotate, and accordingly power generation is carried out. Energy conversion is carried out through a hydraulic control system, and a plurality of hydraulic cylinders can be arranged for improving the energy conversion efficiency.

Description

technical field [0001] The invention relates to ocean current energy power generation, in particular to a method for converting ocean current energy into mechanical rotation of a vertical axis for power generation. 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 generator con...

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
