Offshore energy comprehensive utilization device

Abstract

The invention relates to an offshore energy comprehensive utilization device which comprises an offshore platform, a wave power generation system and a wind power generation system. The wind power generation system is a wind-driven generator, and the wave power generation system and the wind power generation system are installed on the offshore platform and electrically connected through output electric wires. The wave power generation system comprises one or more wave-driven generators, wherein each wave-driven generator comprises a floating body, the floating body is connected with a mechanical transmission generation part through a spur gear, and the mechanical transmission generation part is arranged on the platform top of the offshore platform and comprises a spur gear limiting assembly, a first rotary shaft and a first gear arranged on the first rotary shaft. The spur gear penetrates the platform top from bottom to top and is meshed with the first gear, and the spur gear limiting assembly abuts against the spur gear. The offshore energy comprehensive utilization device is ingenious in design, capable of effectively utilizing marine renewable energy sources and providing the energy sources for ocean development away from the land, is safe, stable and reliable and facilitates engineering implementation and routine maintenance.

Description

technical field [0001] The invention relates to the field of marine energy utilization, in particular to a device for comprehensive utilization of marine energy. Background technique [0002] Wave energy is ubiquitous and abundant in the ocean. The wave energy generation system generally has an energy absorption device and an energy conversion device. The energy absorption device absorbs wave energy and converts it into mechanical energy in a regular motion form (such as linear motion, circular motion), and then converts the mechanical energy in a regular motion form through the energy conversion device. converted into electrical energy output. Divided from the structural form of absorbing wave energy, it can be divided into oscillating water column type, float type, pendulum type and nodding duck type. Energy conversion systems include air impellers, low-head water turbines, hydraulic systems, mechanical systems, and generators. [0003] Since 1964, the world's first sma...

AI Technical Summary

Problems solved by technology

Placing a wind power system on a swaying hull does not consider the relative stability requirements of the power generation system. When encountering large waves, its structure, mooring system and transmission lines are often easily damaged

The shore-type wave energy device is fixed on the shore, but the disadvantage is that the wave energy flow density on the shore is often too small

also doesn't fit with the idea that we expect ocean development far from land to provide energy
