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 dam

The invention belongs to the field of ocean engineering pile foundation scouring protection, and discloses a turbulent flow type ocean engineering foundation comprehensive scouring protection device based on a multi-stage vortex breaking device. The turbulent flow type ocean engineering foundation comprehensive scouring protection device comprises frustum-shaped vortex breaking devices and a biological soil fixation passive protection device which are arranged around a pile foundation body, the frustum-shaped vortex breaking devices comprise horizontal frustum-shaped vortex breaking devices and vertical frustum-shaped vortex breaking devices, the two frustum-shaped vortex breaking devices are arranged on the periphery of the pile foundation body in a staggered mode, and vortex energy dissipation holes are evenly formed in the peripheries of the frustum-shaped vortex breaking devices; every two vertical frustum-shaped vortex breaking devices communicate with each other through a plurality of sets of annular pipe cavity channels, and a wave type wave maker provides annular flow field gas for energy dissipation; a wave type gas making device is installed on the upper part of the horizontal frustum-shaped vortex breaking devices and communicates with the vortex energy dissipation holes of the vertical frustum-shaped vortex breaking devices; and the horizontal frustum-shaped vortex breaking devices are connected with the biological soil fixation passive protection device through an elastic piece. Damage of scouring to the pile foundation body can be reduced, the protection effect is improved, and the problem of secondary scouring is solved.
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...
