Disturbed marine foundation comprehensive scour protection device based on multi-stage vortex breaking device

Abstract

The invention belongs to the field of scouring protection for marine engineering pile foundations, and discloses a turbulent type marine foundation comprehensive scouring protection device based on a multi-stage vortex breaking device, which includes a prism-shaped vortex breaking device and a biological solid The soil passive protection device, the truss-shaped vortex-breaking device includes a horizontal prism-shaped vortex-breaking device and a vertical prism-shaped vortex-breaking device. Vortex energy-dissipating holes are evenly arranged around the center; every two vertical prism-shaped vortex-breaking devices are connected through multiple sets of annular tubes, and the wave-type wave generator provides gas in the annular flow field for energy dissipation; the wave-type wave generator The air device is installed on the upper part of the horizontal prism-shaped vortex-breaking device and communicates with the vortex energy dissipation hole of the vertical prism-shaped vortex-breaking device; the horizontal prism-shaped vortex-breaking device is connected to the biological soil-fixing passive protection device through elastic parts. The invention can reduce the damage to the pile foundation itself by scouring, improve the protection effect, and solve the problem of secondary scouring.

Description

technical field [0001] The invention relates to a marine engineering pile foundation scour protection device, in particular to a flow-disturbing marine foundation comprehensive scour protection device based on a multi-stage vortex breaking device. Background technique [0002] With the rapid development of the global economy, the demand for energy is increasing day by day. Due to the continuous consumption of fossil energy such as oil, coal, and natural gas, and the environmental pollution problems they bring, people are increasingly pursuing new energy sources that are pollution-free and sustainable. . As a kind of abundant, widely distributed, clean and renewable energy, wind energy has naturally been widely valued and is applicable to almost all parts of the world. It is one of the most important alternative energy sources. People first used wind turbines on land to convert wind energy into electrical energy and store it. However, compared with land wind turbines, offsho...

AI Technical Summary

Problems solved by technology

To sum up the above methods, the existing active protection effect only slows down the water flow and reduces the strength of the vortex itself in the process, so as to achieve the purpose of protection, and cannot fundamentally solve the problem of the vortex generated by the flow around the cylinder

Passive protection has problems such as secondary erosion, bottom erosion, and cable damage, which cannot provide long-term effective protection, nor can it solve the problem from the root cause

In reality, ocean currents and vortices change in multiple directions. Existing methods have less consideration for complex sea areas such as waves and reciprocating flows, and there are situations such as shortening the protection period and increasing the difficulty of installation.
