Description

Floating body unit and combined water platform

Technical field

The invention relates to an offshore engineering infrastructure, an offshore power generating device and an offshore engineering platform, in particular to a submersible floating water platform in which a power generating device is integrated and installed on a floating floating body unit, and a floating body unit is combined.

Background technique

At present, the way humans use energy is facing a transformation and upgrading. In particular, China's coal-based power generation methods urgently need to be replaced by clean energy. Ocean energy belongs to clean energy, mainly including wind energy, wave energy, solar energy and ocean current energy. The ocean can have a large amount of reserves in the total ocean water, and the energy per unit volume and unit area is small. In other words, if you want more energy, you have to get it from a large area of sea or a lot of sea water. Ocean energy is renewable and can be said to be inexhaustible.

The ocean accounts for 70% of the Earth's surface and is the largest solar and wind energy absorber. The wind energy transfer rate is related to the wind speed and also the distance between the wind and water. The ocean's wave energy reserves are huge. On the sea surface per square kilometer, the moving waves contain about 300,000 kilowatts of energy, and the global wave energy that can be developed is about 3 billion kilowatts.

According to the research report, the wind speed over the Chinese sea is estimated to be more than 7 m / s per year, that is, the wind power density is more than 200 watts per square meter. Offshore, the higher the wind power density, the total wind energy resources are very considerable. In the sea area of more than 150 kilometers east of Shanghai, the annual average wave height is more than 2 meters. From this, it is estimated that the average annual wind power density above 70 meters is about 600 watts per square meter. In general, the wind energy and wave energy resources in China's seas are very rich and have commercial development value.

The energy of the wave is proportional to the square of the wave height, the period of motion of the wave, and the width of the wavefront. 95% of the wave energy is contained in the water layer and the water layer with a depth of 1/4 wavelength. At present, the wave energy generating device can be described as a variety of things, nothing more than the use of wave motion potential difference, reciprocating force, buoyancy to generate power, the main methods of use are three: 1. Use the ocean wave to push the conversion device up and down to drive the generator to generate electricity; The ocean wave is used to push the front and back of the conversion device to drive the generator to generate electricity; 3. The low-pressure water of the large wave is turned into a small volume of high-pressure water and sent to the high-level pool for accumulation, and then the lower hydro-generator is driven to generate electricity.
