Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0037] like figure 1As shown, the wind turbine 1 is fixed on a barge type or semi-submersible floating platform 2, and the sea wind drives the wind turbine to rotate and generate electricity. A thermoelectric power generation system is arranged on the floating platform. Including hot seawater circulation, working fluid circulation, cold seawater circulation. In the hot seawater circulation, the wave energy utilization device 3 has an inlet connected to the surface seawater, and an outlet connected to the flasher 4, and the surface seawater is pumped into the flasher 4, and the flasher evaporates the seawater into water vapor, and then transfers energy to the The working medium condenses into a liquid state, and finally flows into the wave energy utilization device 6, it...

Abstract

The invention discloses a comprehensive deep sea energy utilizing system. The comprehensive deep sea energy utilizing system comprises a wind turbine, a temperature difference energy generating device, a wave energy utilizing device and an ocean current energy utilizing device. The temperature difference energy generating device comprises a flash evaporator, a working medium circulating unit and a generator, liquid working medium in the working medium circulating unit is delivered to an evaporating heat exchanger via a working medium pump, is changed into unsaturated air by absorbing heat in the evaporating heat exchanger to push a steam turbine to act, and then enters a condensing heat exchanger to be condensed into liquid to flow back to the working medium pump. In the ocean current energy utilizing device, the upper end of a tower column is fixed connected at the bottom of a floating platform, a hydraulic turbine for driving the working medium pump is arranged on the tower column and close to the lower end. The wave energy utilizing device comprises a plurality of floater power units which are arranged below the floating platform and close to the sea surface, a water inlet of at least one floater power unit I is communicated with the surface seawater, a water outlet of the one floater power unit I is communicated with the flash evaporator, a water inlet of at least one floater power unit II is communicated with the deep seawater, and a water outlet of the one floater power unit II is communicated with the condensing heat exchanger.

Description

technical field [0001] The invention relates to a system for comprehensive utilization of marine energy, in particular to a system for comprehensive utilization of deep-sea floating offshore wind energy, temperature difference energy, wave energy and ocean current energy. The system focuses on the establishment of a deep-sea energy comprehensive utilization platform, which has good stability and economy. Background technique [0002] There are abundant energy stored in the ocean, among which wind energy, temperature difference energy, wave energy and ocean current energy are inexhaustible green renewable energy. At present, wind energy conversion technology is relatively mature, and the farther offshore the wind speed is, the greater the wind speed. In the future, offshore wind power will develop towards sea areas farther offshore. However, deep-sea wind power generally adopts floating buoys, which are prone to sway and heave due to the influence of waves. Even the wind tu...
