Unidirectional conversion device and power system provided with same

Abstract

Disclosed is a unidirectional conversion device (22). The unidirectional conversion device (22) comprises a power output part and power selected from at least one of a first swinging input shaft (13) for receiving front and rear swinging power, a second swinging input shaft (14) for receiving left and right swinging power and a third swinging input shaft (15) for receiving horizontal swinging power. Further disclosed is a power system including the unidirectional conversion device; the power system comprises one or more unidirectional conversion devices (22); the plurality of unidirectional conversion devices (22) are combined as a whole by means of sharing the swinging input shafts; the unidirectional conversion devices are connected to one or more swinging devices and / or are arranged on the swinging devices; and the power output part is connected to a power load. The unidirectional conversion device and the power system provided with the device can absorb swinging power from different directions simultaneously and have advantages such as high conversion efficiency, high stability, and wide range of applicability.

Description

technical field [0001] The present invention relates to the technical field of power conversion, in particular to the technical field of mechanical energy conversion, and in particular to a one-way conversion device and a power system with the device. Background technique [0002] It is the common goal of all mankind to effectively apply kinetic energy, especially to obtain more irregular green energy in nature. The sea has inexhaustible and inexhaustible "green" renewable energy. In the past century, many countries have invested a lot of money and talents in the research and development of ocean power generation. However, most of today's ocean power generation equipment has factors such as low energy absorption and conversion efficiency, high manufacturing cost, and insufficient ability to resist natural disasters, which has caused the ocean power industry to fail to enter industrial development for a long time.

The sea has inexhaustible and inexhaustible "green" renewable energy. In the past century, many countries have invested a lot of money and talents in the research and development of ocean power generation. However, most of today's ocean power generation equipment has factors such as low energy absorption and conversion efficiency, high manufacturing cost, and insufficient ability to resist natural disasters, which has caused the ocean power industry to fail to enter industrial development for a long time

[0003] Chinese Invention Patent No. 201010561662.8 is titled a wave power generation method and a system for implementing the method. This invention uses a float to swing and float under the action of waves to drive a one-way conversion device to perform one-way rotation power generation. Although the power generation disclosed in this invention The method and the system implementing this method can directly drive the generator assembly to generate electricity by wave energy in the form of mechanical energy, but in the ocean, due to the instability of the wave energy direction, it can only absorb the back and forth kinetic energy of the wave in one direction. Simultaneously absorbing the side kinetic energy and multi-angle wave energy of sea waves requires installing more power generating devices at different angles and orientations at the same time, resulting in low efficiency of sea wave absorption by the power generation method disclosed in the invention and the system implementing this method, and cost input High and low output efficiency
