Problems solved by technology

[0006] During the treatment of biomimetic aquatic plants, the flow velocity of some seabeds is relatively fast, and the particle size of the sand particles is small, so it is impossible to form a biomimetic grass area with effective deposition and coverage, and the cost is high

Embodiment Construction

[0057] Such as Figure 1~Figure 10 Among them, the fast-assembled and anti-scouring combined offshore wind power foundation includes a foundation body 1, an anti-scouring filter screen 2, a spoiler 3 and a connecting piece 4; the lock 42 at one end of the connecting piece 4 and the anti-scouring filter screen The buckle 22 of 2 is hooked, the bottom plate 21 of the anti-scouring filter screen 2 is connected with the legs 12 of the basic body 1, and a plurality of spoilers 3 are connected with the anti-scouring filter screen 2; the basic body 1 is located in the anti-scouring filter screen 2 , the spoiler 3 is suspended in the anti-scouring filter screen 2 . The structure is simple. By setting the anti-scouring filter screen 2 outside the foundation body 1, the legs 12 of the foundation body 1 are connected to the bottom plate 21 of the anti-scouring filter screen 2, and the single pile is connected to the cover plate 14 on the upper end of the foundation body 1. The anti-scour...

Abstract

The invention relates to a rapidly-assembled and anti-scouring combined type offshore wind power foundation and a method. The rapidly-assembled and anti-scouring combined offshore wind power foundation comprises a foundation main body, an anti-scouring filter screen, a turbulent flow device and a connecting piece; the foundation main body is sleeved with the anti-scouring filter screen; supporting legs of the foundation main body are connected with a bottom plate of the anti-scouring filter screen; a single pile is connected with a cover plate at the upper end of the foundation main body; an inclined steel cable at the bottom of the anti-scouring filter screen is connected with the bottom plate and connected with a retaining ring at the upper end of the anti-scouring filter screen and a lug ring on the single pile through the two ends of the connecting piece respectively; and the turbulent flow device is connected with a node of the conical anti-scouring filter screen in a tightened state, overhangs in the anti-scouring filter screen and sinks into the bottom plate in a seabed rock hole through the foundation main body to make contact with the bottom of the hole. The problems that an original wind power single pile foundation is relatively low in protection performance and stability, long in construction period and high in cost are solved, and the combined type offshore wind power foundation has the advantages of being simple in structure, high in structural strength, good in stability, good in protection performance, capable of being rapidly assembled, short in construction period, easy and convenient to operate and low in maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power, and relates to a rapidly assembled and anti-scour combined offshore wind power foundation and method. Background technique [0002] After the oil crisis in the 1970s, a new era of wind energy utilization began. On land with good geographical location, the development of wind energy has a certain economic value. At the same time, people find that the economics of offshore wind power generation are also quite good. Because there are no obstacles, the wind speed at sea is 20 times higher than that on land. %-100%, the power generation efficiency will be improved accordingly. Offshore wind power is an important field of renewable energy development and one of the important directions of global wind power generation in recent years. Offshore wind power has the characteristics of rich resources, high utilization hours of power generation, no occupation of land, no consumption of water res...
