Submerged floating energy-gathered guiding type wave power generation platform

Abstract

The invention provides a submerged floating energy-gathered guiding type wave power generation platform and belongs to the field of ocean engineering and wave power generation equipment technologies. The submerged floating energy-gathered guiding type wave power generation platform is high in wave energy utilization rate and comprises a submerged floating body, an energy conversion device and a mooring system. The platform can adapt to multiple working conditions by controlling and adjusting ballast water quantity in ballast tanks in the submerged floating body through an automatic adjusting ballast water system and can not be affected by tide level changes and water level changes. The platform can adapt to wind wave current force in different directions by adjusting the mooring system so that a swing board on the platform can be adjusted to the head sea working direction. The wave end of the submerged floating body is provided with a contracted energy-gathered guiding wave path and can substantially improve the wave energy conversion rate. The bottom of the submerged floating body is provided with an electric generator, storage batteries and other energy conversion devices. The maintenance cost is low, the conversion distance from mechanical energy to electric energy is shortened, and the generating efficiency is improved. According to the submerged floating energy-gathered guiding type wave power generation platform, a power generation system can be established in a nearshore sea area just through the manner that the submerged floating body is located through anchor chains, and the submerged floating energy-gathered guiding type wave power generation platform is a reliable, efficient and economical marine power generation platform.

Description

technical field [0001] The invention relates to a submersible-floating energy-gathering-guided wave energy generation platform, which belongs to the technical fields of wave energy generation, clean energy and ocean engineering equipment. Background technique [0002] Ocean wave energy is an endless renewable energy resource. How to use such abundant energy resources to serve human beings has been an important topic that people have been studying, and using wave energy to generate electricity is one of the major topics. [0003] At present, from the domestic and foreign research situation, wave power generation devices mainly include: (1) Oscillating water column type wave power station. The advantage of this type of device is that there are few underwater moving parts, energy is transmitted through the air medium, and the destructiveness of waves is reduced; the disadvantage is that construction is difficult, expensive, and the efficiency of the secondary conversion device ...

AI Technical Summary

Problems solved by technology

The power station is located on the shore, and it is a concrete wave retaining dam. The side of the wave channel connected to the sea has a wide opening, and then gradually narrows to the reservoir. It involves expensive and large-scale construction projects, which has a great impact on the ecological environment. The advantage is that there are few moving parts in the water, and the reliability is high; the disadvantage is that it has strict requirements on the terrain, and is restricted by many factors such as shoreline topography, tidal range, and coastal protection. It can only collect waves in one direction, and the wave energy utilization rate is low.

It is not difficult to find out from the analysis and study of the current situation of the development and utilization of marine energy at home and abroad that the current fixed-type common shortcomings of various wave energy generation systems mainly include: low wave energy conversion efficiency, poor ability to adapt to waves and tidal ranges in different directions, Poor typhoon resistance, difficult to maintain, immobile
