Background
The single pile foundation is one of the most widely used structural forms of offshore wind power. The ocean environment often has complicated ocean current effect, and the ocean current effect can corrode the seabed around the pile foundation because of the undercut that single pile structure separation produced, causes local scouring. The harm brought by local scouring can not be small, the sediment deposition around the single pile foundation is influenced, and the lateral bearing capacity and the seismic performance of the single pile structure can be reduced. Therefore, how to adopt proper protection measures and reduce local scouring around the single-pile foundation is an important problem to be considered in the design of the offshore wind power single-pile foundation.
Numerous experts and scholars carry out intensive research on anti-scouring measures of single-pile foundations, wherein the most common protective measures comprise three measures, namely stone throwing protection, sand quilt protection and solidified soil protection. Overall, each of these three protective measures has advantages, but there are problems of varying degrees. In order to make up for the defects of the existing protective measures, a novel protective measure needs to be provided, and the problem of single-pile foundation scouring is effectively solved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the technical problem that exists among the known art and provide an offshore wind power single pile basis flexible energy dissipation anti-scouring device, can show the energy that reduces pile foundation incident flow face, effectively alleviate the circumstances that silt erodees around the single pile and runs off.
The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the flexible energy dissipation and anti-scouring device for the offshore wind power single pile foundation comprises a soft body row paved around a pile foundation, wherein the soft body row is formed by connecting flying saucer type concrete blocks which are vertically arranged in rows transversely, the lower part of each flying saucer type concrete block is a circular truncated cone, the upper part of each flying saucer type concrete block is a hemisphere, every two adjacent flying saucer type concrete blocks are connected through a connecting rope, and a sand bag is filled in a gap between each soft body row and the pile foundation.
Four connecting ropes which are uniformly distributed along the circumferential direction and extend along the radial direction are arranged around the flying saucer type concrete block.
The connecting rope is pre-buried in the flying saucer type concrete block body, is arranged at the joint of the circular truncated cone body and the hemispheroid, and transversely penetrates through the flying saucer type concrete block body.
The diameter of the bottom of each flying saucer type concrete block is 900mm, the height of each hemisphere is 200mm, and the distance between every two adjacent flying saucer type concrete blocks is 100-200 mm.
The utility model has the advantages and positive effects that: the soft body row that adopts connecting rope and flying saucer type concrete block to constitute can weaken water flow energy, reduces the pile foundation velocity of flow around, effectively solves the problem that silt runs off because of scouring around the pile foundation. Compared with the traditional protective measures, the connecting rope and the concrete block are poured and fixed, so that the construction process can be simplified, and the construction cost can be reduced. And the soft raft is prefabricated on land, is convenient to manufacture, and is beneficial to ensuring the quality and the efficiency. The device has strong applicability, wider application range to the surface of the sea bed, stronger capability of resisting wind waves and currents, more contribution to maintaining the stability of the device and wide application prospect.

Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:
referring to fig. 1 to 5, the flexible energy dissipation and erosion prevention device for the offshore wind power single pile foundation comprises a soft body row which is laid around a pile foundation 1, wherein the soft body row is formed by connecting flying disc type concrete blocks 3 which are arranged in rows and columns, the lower parts of the flying disc type concrete blocks 3 are round platforms, the upper parts of the flying disc type concrete blocks 3 are hemispheres, two adjacent flying disc type concrete blocks 3 are connected through connecting ropes 4, and sand bags 2 are filled in gaps between the soft body row and the pile foundation 1.
In this embodiment, be equipped with four along circumference equipartition, along radial extension around flying saucer type concrete block 3 connect rope 4, it is pre-buried to connect rope 4 in flying saucer type concrete block 3, set up in the round platform body with the junction of hemispheroid, and cross flying saucer type concrete block 3. Simple structure and convenient manufacture. The connecting rope 3 is an anti-aging polypropylene rope with the diameter of 16 mm. The diameter of the bottom of the flying saucer type concrete block 3 is 900mm, the height of the hemisphere is 200mm, and the weight of the hemisphere is 95.6 kg. The distance between two adjacent flying saucer type concrete blocks is 100-200 mm.
The installation method of the device comprises the following steps: the concrete soft raft is prefabricated on land, transported to a fan site by sea, and then transferred to a spread ship by using a truss for hoisting. Before installation, firstly, broken stones are laid in an area where an anti-scouring device is arranged around a pile foundation to level the sea bottom surface, then a laying ship is positioned by a GPS, and then a soft body is sunk to a seabed fixed position; and finally, pressing a sand filling bag at a gap between the pile foundation and the anti-scouring device to avoid the sand from overflowing from the gap.
