Compressed-gas type sea wave power generating device

Abstract

The invention relates to a power generating device, namely a compressed-gas type sea wave power generating device which takes sea waves as a power source. The invention provides a power generator which can utilize high-energy surges formed by concentrating spreading sea waves on a sea surface to a shoreside during rising tides and falling tides, high waves and wavelets, can utilize an oscillating buoy or an oscillating water column of a primary energy conversion mechanism and can drive a tertiary energy conversion mechanism through a pushing-pulling distance-limiting mechanism, an air compressor, a gas storage tank and an air turbine motor of a secondary energy conversion mechanism, so that high-energy surges are converted into stable and strong constant electric energy. The compressed-gas type sea wave power generating device has the advantages that: firstly, air is generally used as an energy conversion medium, so that air transmission energy loss is the least and the air is the best energy storage medium; secondly, the a water moving part is not arranged in the whole device; thirdly, the structure is simple, the building cost is low and the maintenance is convenient; fourthly, the field construction is simple and easy; fifthly, a plant is built on shore; sixthly, a large sea wave power generation field can be built; seventhly, an effect of protecting the shore is also achieved. The device is a relatively ideal sea wave power generating device among the existing lots of sea wave generating devices.

Description

technical field [0001] The invention relates to an energy conversion technology, in particular to the technology of generating electricity by using ocean shore waves. Background technique [0002] Now energy shortage and environmental pollution have become major problems facing the world. More than 70% of the Earth's surface is covered by oceans. The vast ocean contains huge energy. Taking wave energy as an example, it has the characteristics of high energy density and wide distribution. Ocean wave energy is one of the inexhaustible renewable clean energy sources, much superior to wind energy and solar energy, and is a long-term wish of people. Since ancient times, it has attracted skilled craftsmen along the coast, trying various methods to control the waves for human use. Ocean wave energy scholars now estimate that waves travel thousands of kilometers in the ocean without significant attenuation, and finally gather on the shore. Some people have done a test, the impac...

Problems solved by technology

Most of the wave power generation devices invented at present are placed in the water. Typhoon weather often occurs in the marine environment, which will damage the underwater devices, sea water will corrode the marine devices, and shellfish will parasitize the underwater devices, making the devices easy to damage
