Benefits of technology

This technology helps prevent damage caused from seawater flooding during construction or maintenance operations on ships' hulls. It uses multiple layers of grids that are placed at different angles around an axis called the tilting plane. By adding these gratings, it can help decrease the velocity of water moving across this area while also blocking any debris falling into the ship' s deck space. Overall, this technology improves the efficiency and effectiveness of marine structures used for protection against damaging environments such as waves.

Problems solved by technology

This patented technical solution for prevention against scuffs in sea water power plant (SWP) structures involves adding special materials that can be used inside them during construction or maintenance operations without affecting their overall functioning negatively impacting its performance.

Embodiment 1

[0030] Such as figure 1 As shown, a pile foundation anti-scouring system for offshore wind power according to the present invention includes a slope section system 1, a top section system 2 and a three-dimensional support structure.

[0031] The three-dimensional support structure is in the shape of a trapezoid, including a base 5, a top horizontal plane 7 and an inclined slope 6; the inclined slope 6 connects the base 5 and the top horizontal plane 7; the base 5 is buried in the seabed and fixed. The included angle between the inclined slope 6 and the horizontal plane is an angle α; the base 5, the top horizontal surface 7 and the inclined slope 6 together form a three-dimensional support structure. The range of α angle is generally 30°-60°.

[0032] The slope section system 1 and the top section system 2 are both grid structures; the top section system 2 is installed vertically on the top horizontal surface 7, and the slope section system 1 is vertically installed on the incli

Embodiment 2

[0040] The present invention also provides a method for anti-scouring of pile foundations of offshore wind power, based on the anti-scouring system of pile foundations of offshore wind power in Embodiment 1, comprising the following steps:

[0041] Step 1. The seawater flows through the slope section system 1 on the inclined slope surface 6, and the sediment in the water is partially blocked by the grille 3, and the seawater is also blocked by the slope section system 1 due to climbing and the flow rate decreases;

[0042] Step 2: The seawater flows through the top section system 2 on the top horizontal surface 7, the sediment in the water is blocked, the seawater is blocked by the top section system 2, and the flow velocity drops again to achieve the purpose of anti-scouring of the pile foundation of offshore wind power.

Abstract

The invention discloses an anti-scouring system and method for a pile foundation of offshore wind power. The anti-scouring system for the pile foundation of the offshore wind power comprises a slope section system, a top section system and a three-dimensional supporting structure, wherein the three-dimensional supporting structure is trapezoidal and comprises a base, a top horizontal surface and an inclined slope surface, and the inclined slope surface is connected with the base and the top horizontal surface; the slope section system and the top section system are each of a grid structure, the grid system is composed of grids and stand columns, and each grid is vertically fixed by two stand columns; the vertical slope section system is arranged on the inclined slope surface, and the vertical top section system is arranged on the top horizontal surface. According to the anti-scouring system for the pile foundation of the offshore wind power, through a multi-layer grid structure, the water flow velocity is slowed down, and silt close to the bottom layer of a seabed is blocked; through the inclined slope surface of the three-dimensional supporting structure, the flow resistance is further increased, and the water flow speed is reduced; through the combination of the three-dimensional supporting structure and the grid structure, the seabed roughness is remarkably increased, the water flow speed is reduced, and the foundation anti-scouring purpose is achieved.
