A floater type wave energy generating device for sea islands

Abstract

The invention relates to a float-type wave energy power generation device for a sea island. According to the basic working principle, potential energy of waves is absorbed by a floating body floating on the sea, kinetic energy of the waves is absorbed through an impeller on the floating body, the potential energy and the kinetic energy are transmitted to a transmission mechanism in a sinking box through a steel cable arranged between the floating body and the sinking box, and accordingly electric generators are driven to generate electricity. The float-type wave energy power generation device for the sea island has the main beneficial effects that the electric generators are arranged on the two sides of a torsion cable winding device, and thus the electric generators can be used for generating the electricity in the positive and negative rotating process of the torsion cable winding device; meanwhile, a wind driven generator is arranged in a float so that the float-type wave energy power generation device can effectively use continuous wind energy on the sea for generating the electricity, and hence the power generation device can give out electric energy continuously and stably through the combination of the three electric generators; the wave energy power generation device is simple in structure, and both manufacturing cost and maintenance cost are low; meanwhile, due to the simple structure, the device can be arranged in the ocean in a large-area mode, afterwards, the electric energy is concentrated and then stored, and therefore the electric energy can be better obtained continuously and stably.

Description

technical field [0001] The invention belongs to the field of marine wave energy generating devices, in particular to an array float type anti-wind wave wave energy generating device for sea islands. Background technique [0002] In my country, the sea area is vast and has huge ocean energy resources, especially the South China Sea. Most of the South China Sea is surrounded by islands and archipelagos; compared with the ocean, the land area is small, and it is difficult to generate electricity on land. Since most of the islands in the South China Sea are far away from land, they lack energy supply. To realize the sustainable development of my country's islands, it is necessary to adapt measures to local conditions, make full use of ocean energy, and reduce dependence on fuel supplies. [0003] Wave power generation is the main way to utilize wave energy, which can provide clean energy for remote islands and offshore facilities. At present, the relatively mature method of w...

Problems solved by technology

At present, the relatively mature method of wave energy utilization is the oscillating water column method. This method requires the construction of dams, the construction cost is relatively large, and the land area occupied by the unit power is relatively large, so it is not suitable for islands.

In addition, there are other methods such as nodding duck and sea snake. These methods are subject to greater stress during large waves and poorer equipment safety performance.

Generally speaking, most of the existing wave power generation devices are large-scale single structures, with complex structures, poor wind and wave resistance, and many shortcomings
