Direct drive type electricity generating device using ocean energy

Abstract

A direct drive type electricity generating device using ocean energy comprises a floater (1.1), a retraction rope (1.2), a hanging wire cable (1.3), a direct drive electricity generator (1.4) and a tail fin (1.5). The floater (1.1) floats on the surface of the sea and is connected with the direct drive electricity generator (1.4) through the hanging wire cable (1.3), one end of the retraction rope (1.2) is connected with the floater (1.1), the other end of the retraction rope (1.2) is arranged above an offshore operation unit, and the retraction rope (1.2) is used for placing the electricity generating device in the sea or withdrawing the offshore operation unit by workers. The direct drive type electricity generating device using the ocean energy is characterized by also comprising a sea anchor (1.6) and a steel warp (1.7), the tail fin (1.5) and the direct drive electricity generator (1.4) are arranged at a position of a water outlet of the sea anchor (1.6), the sea anchor (1.6) is used for collecting ocean current, a blade (3.6) of the direct drive electricity generator (1.4) is used for capturing sea kinetic energy and converting the sea kinetic energy to electric energy for outputting, one end of the steel warp (1.7) is connected with the sea anchor (1.6), and the other end of the steel warp (1.7) is fixed on the offshore operation unit.

Description

technical field [0001] The invention relates to a direct-drive ocean energy generating equipment. technical background [0002] With the increasing shortage of petroleum resources, the utilization and development of renewable energy is particularly important. Ocean energy resources, as a renewable energy attached to seawater, have huge reserves. At present, the power supply of ocean-going fishing boats, offshore platforms and other offshore operating units is realized by diesel power generation. This power generation method not only has high economic costs, but also causes pollution to the marine environment. The use of marine renewable resources to generate electricity is a sustainable way of generating electricity, which can alleviate human dependence on fossil energy to a certain extent. [0003] At present, there is still relatively little research on ocean current power generation at home and abroad. Most of the existing power generation devices use a turbine to drive ...
