Description

Underwater installation method of marine energy generation facility {Construction of tidal and wave power generating station under water}

The present invention relates to an underwater installation method of a marine energy power generation facility, and more particularly, a number of formed by fixing a pier manufactured in a shipyard dock or barge and launched by buoyancy to the seabed along a coastline with high tide and high waves Block the waterway with an arc-type waterproof sluice gate and construct a power generation facility, or set up an arc-type waterproof sluice gate coupled to a pier steel bar at a shipyard dock or barge as a support and launch a plurality of power generation facility skeletons manufactured by set with buoyancy to build a bedrock along the coastline. It relates to an underwater installation method for marine energy power generation facilities that saves construction costs and shortens the construction period by excluding the process of installing temporary water barriers using earth stones, etc.

In order to construct a 400m tidal power plant and a drainage sluice in the Sihwa district embankment with a width of about 100m, which was completed a long time ago and is already being used as a 4-lane main road and a 2-lane secondary road, a temporary water barrier of nearly 2km was installed with cylindrical steel pipes, etc. The construction was stopped for six months, and it was constructed for six years at a cost of hundreds of billions of won, but the amount of power generation is only 25,000 kw due to water supply.

The main reason why the renewable energy of the five oceans, which is more than five times the world's power generation, has not yet been properly utilized is probably because the investment cost and construction period for efficient power generation facility construction cannot guarantee business feasibility, or straightening roads or rainy season It is thought that it is because it would be more economical and convenient to rely on fossil fuels, unless it is a tidal power plant that is built incidentally to the embankment built to prevent the habitual invasion that is repeated every time.

Tidal power generation is more effective in increasing the amount of power generation than tidal power generation, rather than power generation by forging, because the high tide and ebb tide are repeated at a cycle of about 12 hours and 50 minutes instead of having a narrow drop. will make a contribution

However, when power generation facilities are installed on some of the long embankments, such as forged tidal power plants, ocean energy cannot be sufficiently secured with short power generation facilities. Since only the power generation efficiency will drop significantly, the construction of embankments that have no useful value will only waste a huge amount of money.

In particular, in the case of constructing a power generation facility like an island in the middle of the sea, the cost and construction period of access roads and water barriers will far exceed the main construction. I wonder if this is the reason why they are not ready to confront the sea energy even though they are well aware of its potential.

By creating a reservoir with an embankment composed of overpass waterways, wave power generation facilities, and tidal power generation facilities with different functions, water for water generation is secured during water input and power generation, and the drop in water supply and power generation is secured during drainage and power generation. Water-repellent power generation is promoted from tidal power generation facilities and wave power facilities. In particular, wave power generation continues regardless of tides as long as there are waves.

A plurality of waterways formed by arranging piers manufactured in a dock or barge at a shipyard so that the top is exposed along the coastline with high tide and high waves are blocked with waterproof sluice gates, and wave power generation facilities, tidal power generation facilities, and seawalls built with overpass waterways are installed. By fixing to the seabed bedrock or manufacturing a plurality of power generation facilities in a movable set unit, fixing them to the seabed, and finishing the rest of the work such as the deck, the temporary water barrier process as well as the residual soil treatment will be omitted or reduced.

From the production and launch of power generation facilities on a barge or dock to the start of test operation, all processes are carried out wisely with increasingly familiar proficiency and organic collaboration and division of labor. As long as it is not damaged, it is continuously recycled, and barges in particular are moved for the construction of the next offshore power plant.

Comparing the functions of the three types of power generation facilities built along the coastline,

① Wolpa canals, which are mainly installed in shallow places, pump water for power generation by rising tide and waves and store it in a reservoir or use it as drainage water for power generation of wave power facilities and do not generate electricity.

② The tidal power generation facility installed in the deep place divides the waterway into upper and lower waterways, and the lower waterway secures the drop in water supply power generation by generating water stored in the reservoir during low tide, and secures water for power generation by water input power generation during high tide. In the later stage, water for pumped-storage power generation is pumped using aberration power using surplus power generation water, or additionally drained to reservoirs or open seas drained to the low tide level at the beginning of the high tide to further lower the water level, and the upper waterway is generated by waves and rising tide that landed above the aberration Securing water or using it as drainage water for wave power generation facilities.

③ In the wave power generation facility installed in a relatively deep place, the rising water that lands with the waves while rotating the vertical water wheel joins the high water that has landed through the Wolpa sluice and is stored in a reservoir or used as drainage power generation water for the vertical water wheel. In particular, when the water level in the reservoir is too high or the water entry window is blocked even though it has landed through the Wolpa canal and the tidal power plant, it is drained into the water for power generation of the wave power plant through the canal through the pier to lower the water level of the next wave. Helps.

④ A transverse aberration requires water for power generation or a sluice gate to secure a drop. By accelerating the speed of water, which slows down whenever the water level falls or the water level reverses, you can get much more water than the open sea level in a short time, and you will be able to compensate for the insufficient water power generation.

In order to save investment costs and shorten construction period by omitting the temporary water barrier process or reducing the scale when constructing marine energy power generation facilities, the present invention is manufactured by set using piers or waterproof sluice gates manufactured in docks or barges at shipyards as supports. From the multi-stage fixation of a number of power generation facilities to the sea bed rock along the coastline to the completion of the remaining process, almost any water-blocking process other than the waterproof gate and waterproof curtain is excluded, and the formwork, as well as the waterproof gate, waterproof curtain, and buoyancy device are recycled. do.

In particular, when manufacturing piers or power generation facility sets, the purpose is to increase the construction speed by increasing the level of proficiency through division of labor and collaboration until the remaining work is completed, and to reduce construction costs by excluding the residual soil treatment work.

In order to achieve the above object, in the embankment construction process built along the coastline with high tide and high waves, the pier 101 manufactured in the dock or barge 30 at the shipyard is fixed to the seabed and is multi-stage with the waterproof sluice gate 107 Embankment 10 installation process in which power generation facilities are built one by one in a plurality of connected waterways, or
