Compared with land wind energy, offshore wind energy resources not only have higher wind speed, but also are far away from a coastline, are not influenced by a noise limit value, and allow the unit to be manufactured in a larger scale.

The offshore wind power foundation is the key point for supporting the whole offshore wind power machine, the cost accounts for 20-25% of the investment of the whole offshore wind power, and most accidents of offshore wind power generators are caused by unstable pile foundation. Due to the action of waves and tide, silt around the offshore wind power pile foundation can be flushed and form a flushing pit, and the flushing pit can influence the stability of the pile foundation. In addition, the water flow mixed with silt near the surface of the seabed continuously washes the pile foundation, corrodes and destroys the surface of the pile foundation, and can cause the collapse of the offshore wind turbine unit in serious cases. The anti-scouring device of the currently adopted offshore wind power pile foundation is mainly a riprap protection method.

The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

An offshore wind power suction canister foundation 100 according to an embodiment of the invention is described below with reference to fig. 1-4.

First, briefly describing the principle of the suction tube 3, those skilled in the art will appreciate that the suction tube 3 is similar in structure to a water bucket, including an annular tube body and a rounded end. The installation principle of the suction barrel 3 is similar to that of a cupping glass, after the suction barrel 3 is placed on the surface of a sea bed, the sea water in the suction barrel 3 is sucked out by a water pump, the pressure in the suction barrel 3 is reduced, and the suction barrel 3 gradually sinks to the designed depth under the action of the pressure difference between the inside and the outside of the suction barrel 3.

The offshore wind power suction cylinder foundation 100 according to the embodiment of the present invention includes a suction cylinder 3, a column 1, and a spoiler 2. The suction cylinder 3 is buried in the seabed, the top end face of the suction cylinder is exposed out of the seabed, the bottom of the upright post 1 is connected with the suction cylinder 3, the turbulence piece 2 is at least arranged on the top end face of the suction cylinder 3 and protrudes upwards from the top end face of the suction cylinder 3, the size of the turbulence piece 2 in the vertical direction is the height of the turbulence piece 2, and the height of the turbulence piece 2 is 0.1-1.5 m.

In order to make the technical solution of the present invention easier to understand, the technical solution of the present application is further described below by taking as an example that the extending direction of the upright post 1 coincides with the up-down direction, wherein the up-down direction is as shown in fig. 1.

For example, as shown in fig. 1 to 14, an opening is formed at the lower end of the suction tube 3, the upper end of the suction tube 3 is sealed, the end surface of the upper end of the suction tube 3 is a top end surface, the lower end of the suction tube 3 is installed in sand in the seabed, the top end surface of the suction tube 3 is higher than the seabed surface, the upright post 1 extends in the up-down direction, the upright post 1 at the upper end of the suction tube 3 is a first part 11, and the upright post 1 inside the suction tube 3 is a second part 12. The top end face of the suction cylinder 3 is provided with a spoiler 2, and the spoiler 2 extends upwards.

It should be noted that, the direction close to the center line of the suction tube 3 is inward, the direction far away from the center line of the suction tube 3 is outward, the inside of the suction tube 3 is provided with a plurality of spaced-apart sub-chamber plates 4, the inner ends of the plurality of sub-chamber plates 4 are connected with the second part 12, and the outer ends are connected with the suction tube 3, so as to strengthen the structure of the suction tube 3, and make the offshore wind power suction tube foundation 100 more stable.

The vertical direction is the up-down direction, the size of the turbulence member 2 in the up-down direction is the height of the turbulence member 2, and the height of the turbulence member 2 is 0.1m to 1.5 m. For example, the height of the spoiler 2 is 0.1m, 0.2m, 0.5m, 1.2m, 1.5m, or the like.

According to the offshore wind power suction cylinder foundation 100 disclosed by the embodiment of the invention, the suction cylinder 3 is utilized, and foundation construction can be completed without external forces such as a pile driver and the like during offshore wind power operation, so that dependence on large-scale marine equipment is reduced, the construction cost is greatly reduced, and meanwhile, the offshore construction risk is effectively reduced.

In addition, because the vortex piece 2 upwards protrudes at the top end of the suction cylinder 3, when tide contacts the vortex piece 2, the vortex piece 2 can 'break up' tide, the flow speed and the direction of the tide are locally changed, the energy of the tide can be dissipated to a certain extent, a large horseshoe vortex cannot be generated near the suction cylinder 3, the formation of the horseshoe vortex is suppressed at the source, the soil around the suction cylinder 3 is effectively protected, the formation of a scouring pit is avoided, and the foundation of the offshore wind power suction cylinder is more stable.

Therefore, the offshore wind power suction cylinder foundation 100 provided by the embodiment of the invention has the advantages of good turbulence effect, high stability, high construction safety and the like.

In some embodiments, the spoiler 2 is plural, and the plural spoilers 2 are arranged in a radial direction of the suction tube 3, and/or the plural spoilers 2 are arranged in a circumferential direction around the column 1.

For example, as shown in fig. 1 to 13, the spoiler 2 may include a plurality of spoilers 2 arranged in various patterns.

First, a plurality of spoilers 2 are arranged radially in the radial direction of the suction cylinder 3.

Second, a plurality of spoilers 2 are arranged in a plurality of rings around the column 1.

Thirdly, the plurality of spoilers 2 are arranged annularly around the column 1 as viewed in the circumferential direction around the column 1, while the plurality of spoilers 2 are arranged radially as viewed in the radial direction of the suction cylinder 3.

First, the plurality of spoilers 2 arranged in the radial direction of the suction tube 3 include a plurality of different height dimensions, for example, in the radial direction, the heights of the plurality of spoilers 2 are sequentially increased or decreased in the direction close to the column 1.

Second, the plurality of spoilers 2 arranged in the circumferential direction around the column 1 include a plurality of different height dimensions, for example, the heights of the plurality of spoilers 2 in the direction around the column 1 are sequentially increased or decreased.

Thirdly, a plurality of spoilers 2 arranged in the radial direction of the suction tube 3 and arranged in the circumferential direction around the column 1 have a plurality of different height dimensions.

In addition to this, the heights of the spoilers 2 may be randomly distributed.

From this, through setting up different heights, increase the irregularity of spoiler 2, spoiler 2 is when facing trend and horseshoe vortex, can break up the law of flow of trend and horseshoe vortex better and break up in disorder, and the bigger degree changes the flow direction and the velocity of flow of rivers upwards, strengthens marine wind power suction section of thick bamboo basis 100's scour protection ability to make marine wind power suction section of thick bamboo basis 100 can deal with the trend and the horseshoe vortex of multiple energy gradient, has strengthened marine wind power suction section of thick bamboo basis 100's adaptability.

In some embodiments, the spoiler 2 comprises one or more of a spoiler pin, a spoiler strip, a spoiler mesh,

the turbulence nails are arranged on the top end face of the suction barrel 3 at intervals, the length-width ratio of each turbulence nail is greater than or equal to 1/2 and less than or equal to 2, the extending direction of each turbulence strip is parallel to the top end face of the suction barrel 3, the length-width ratio of each turbulence strip is greater than or equal to 5, and each turbulence net is of a net-shaped structure covering the top end face of the suction barrel 3.

For example, as shown in fig. 1 to 13, the spoiler pin includes a plurality of spoiler pins arranged at intervals on the tip end surface of the suction cylinder 3, and the ratio of the size of the spoiler pin in the radial direction of the suction cylinder 3 to the size thereof in the circumferential direction around the pillar 1 is equal to or greater than 1/2 and equal to or less than 2.

Optionally, the spoiler nail is a plurality of, and a plurality of spoiler nails are arranged at intervals in the radial direction of suction tube 3 and/or in the circumferential direction around upright post 1. Optionally, the interval between adjacent spoiler nails is greater than or equal to 0.25D and less than or equal to 1.0D, and D is the outer diameter of the pillar 1.

The flow disturbing strips are of strip structures, and the extending direction of the flow disturbing strips is parallel to the top end face of the suction cylinder 3. Optionally, the ratio of the length to the width of the spoiler strip is equal to or greater than 5. The extension length of the turbulence strip is more than or equal to 0.1D.

The turbulence net is a net structure covering the top end surface of the suction cylinder 3. Optionally, the area of the top end surface of the suction barrel 3 covered by the turbulence net is more than or equal to 0.05 pi Dt²(where Dt is the outer diameter of the suction tube 3). The area of the top end surface of the suction cylinder 3 coated by the spoiler is the area of a figure enclosed by the outer contour of the projection of the spoiler on the top end surface of the suction cylinder 3.

In some embodiments, the spoilers 2 comprise a plurality of types of spoilers nails, spoilers strips, spoilers meshes, and the plurality of types of spoilers 2 are alternately distributed on the tip surface of the suction cylinder 3.

For example, as shown in fig. 9 to 13, turbulators are arranged between adjacent turbulators, or turbulators are arranged in a lattice of a turbulator, or a plurality of turbulators 2 are alternately arranged.

Besides, in other embodiments, the same type of spoiler 2 has different shapes, and the different shapes of spoiler 2 are alternately distributed on the outer circumferential surface of the suction cylinder 3.

For example, the cross section of the spoiler 2 is obtained by cutting the spoiler 2 in a plane perpendicular to the tip end surface of the suction cylinder 3. The cross section of the spoiler 2 can be made into regular geometric figures such as triangle, rectangle and semicircle, or irregular figures. When the turbulence nails and the turbulence strips are arranged on the suction barrel 3 at the same time, the turbulence nails at different positions can be provided with different cross-sectional shapes, and the turbulence strips at different positions can be provided with different cross-sectional shapes. In addition, when only one type of spoiler 2 is disposed on the suction tube 3, different cross-sectional shapes may be provided to the spoiler 2 at different positions.

Therefore, the turbulence pieces 2 of various types are alternately distributed, the irregularity of the turbulence pieces 2 arranged on the top end face of the suction cylinder 3 can be increased, the offshore wind power suction cylinder foundation 100 can cope with tides with various energy gradients and horseshoe vortices, and the adaptability of the offshore wind power suction cylinder foundation 100 is enhanced. Moreover, the turbulence elements 2 of various types are alternately distributed, so that turbulence effects of the turbulence elements 2 of different types can be mutually superposed, the energy dissipation and impact reduction effects of the turbulence elements 2 are further enhanced, and the anti-scouring capability of the offshore wind power suction cylinder foundation 100 is enhanced.

In some embodiments, the top end face of suction cylinder 3 is provided with a plurality of turbulators pins and a plurality of turbulators strips,

the turbulence strips are annular and are arranged around the upright post 1, the plurality of turbulence strips are sequentially sleeved, the plurality of turbulence nails are divided into a plurality of groups, each group of turbulence nails comprises a plurality of turbulence nails, and the plurality of turbulence strips and the plurality of groups of turbulence nails are alternately arranged in the radial direction of the suction barrel 3;

or, the vortex strip is along a radial extension of a section of thick bamboo 3 of suction, and the vortex strip includes a plurality ofly, and a plurality of vortex strips set up at the interval in a circumference of a section of thick bamboo 3 of suction, and a plurality of vortex nails divide into the multiunit, and every group vortex nail includes a plurality of vortex nails, and a plurality of vortex strips and multiunit vortex nail are arranged at a circumference of a section of thick bamboo 3 of suction in turn.

For example, as shown in fig. 10 and 11, the spoiler is arranged annularly around the circumference of the column 1, a plurality of annular spoiler having different diameters are arranged around the column 1, and between two adjacent annular spoiler, a plurality of spoiler pins are provided along the circumference of the column 1.

Or, the vortex strips extend along the radial direction of the suction cylinder 3, the plurality of vortex strips are arranged in the circumferential direction of the suction cylinder 3 at intervals and are in an emission shape, and a plurality of vortex nails are arranged in the area between two adjacent vortex strips.

Therefore, the turbulence piece 2 is attractive when the irregularity degree is increased, when the turbulence piece 2 faces to tide and horseshoe vortices, the flow rule of the tide and the horseshoe vortices can be broken up and disturbed better, the flow direction and the flow speed of water flow can be changed to a greater extent, the anti-scouring capacity of the marine wind power suction cylinder 3 foundation 100 is enhanced, the marine wind power suction cylinder 3 foundation 100 can deal with the tide with multiple energy gradients and the horseshoe vortices, and the adaptability of the marine wind power suction cylinder 3 foundation 100 is enhanced. In some embodiments, the spoiler 2 comprises a plurality of two spoilers 2 adjacent in the radial direction of the suction tube 3 and/or two spoilers 2 adjacent in the circumferential direction around the upright 1.

In life, a staggered arrangement is also a common type of arrangement, where this arrangement is applied to the suction tube 3. The spoilers 2 are arranged in a staggered manner in various ways:

first, two adjacent spoilers 2 stagger in the upper and lower direction of a suction section of thick bamboo 3 and arrange, and two spoilers 2 adjacent in the circumferential direction are in same week.

In the second type, two adjacent spoilers 2 are arranged in a staggered manner in the circumferential direction of the suction tube 3, and the two spoilers 2 adjacent to each other in the vertical direction are positioned on the same straight line.

Thirdly, two adjacent spoilers 2 are not only arranged in a staggered manner in the vertical direction of the suction tube 3, but also arranged in a staggered manner in the circumferential direction of the suction tube 3.

Furthermore, the spoilers 2 may also be arranged randomly.

The irregularity of the turbulence piece 2 arranged on the top end face of the suction barrel 3 is increased, and the energy dissipation and impact reduction effects of the turbulence piece 2 and the anti-scouring capacity of the offshore wind power suction barrel foundation 100 are enhanced.

In the related art, the offshore wind power suction cylinder foundation 100 is mainly disposed in a shallow water area where a tidal current mainly approaches to or departs from a coastline along a direction approximately perpendicular to the coastline when the tidal current rises and falls, so that a side of the top end of the suction cylinder 3 facing the coastline and a side facing away from the coastline are places where the tidal current mainly impacts. In the two places of the suction cylinder 3, the impact force of the bearing tide is larger, and the number of scouring pits caused by the vortex is larger. The top end surface of the suction tube 3 has two remaining side surfaces extending in a direction substantially corresponding to the direction of the tidal current, and the two remaining side surfaces of the suction tube 3 are mainly subjected to the frictional force and the small impact force of the tidal current.

In some embodiments, the top end face of the suction tube 3 comprises a front face facing the tidal current direction, a rear face opposite to the front face, and two side faces, the density of the turbulators 2 distributed on both the front and rear faces being greater than the density of the turbulators 2 distributed on both side faces.

For example, the front surface of the top end surface of the suction tube 3 is a surface facing away from the coastline, and the back surface of the top end surface of the suction tube 3 is a surface facing toward the coastline. The spoilers 2 are arranged on the front and back of the top end face of the suction tube 3 with a high density relative to the remaining two side faces of the top end face of the suction tube 3. For example, the front and side surfaces of the suction cylinder 3 are arranged with a spoiler 2 density 2 times higher than the remaining two side surfaces. Therefore, the offshore wind power suction cylinder foundation 100 can not only have strong anti-scouring capacity, but also reduce the manufacturing cost and the manufacturing difficulty.

Alternatively, the density of the spoiler 2 distributed on the front surface may be made smaller than the density of the spoiler 2 distributed on the rear surface.

It will be appreciated that the front and back of the top end face of the suction cartridge 3 are opposed. In many sea areas, the direction of the current is not uniform, for example, in some sea areas, the current flows east and west year after year, and the current flows north and south rarely occur. When the suction tube 3 is subjected to a tidal current of flow of things, the sea beds on the east and west sides of the suction tube 3 are most likely to generate large wash pits, while the sea beds on the south and north sides generate smaller wash pits. At this time, the density of the spoilers 2 arranged on the east and west sides of the tip face of the suction tube 3 is large.

In some embodiments, the spoiler 2 is further provided on the pillar 1, and protrudes from the outer circumferential surface of the pillar 1 in the radial direction of the pillar 1.

For example, as shown in fig. 1, a spoiler 2 is also provided at a lower end of the first portion 11, the spoiler 2 extending radially outward of the pillar 1. Therefore, the flow of the tide is further disturbed around the upright post 1, so that the disturbed flow and impact reduction effect of the disturbed flow piece 2 is enhanced, and the anti-scouring capability of the upright post 1 is enhanced.

In some embodiments, spoiler 2 is also provided on the outer circumferential surface of suction cylinder 3, and protrudes from the outer circumferential surface of suction cylinder 3 in the radial direction of suction cylinder 3.

For example, as shown in fig. 1, a spoiler 2 is provided on a portion of the outer peripheral surface of the suction cylinder 3 near the tip end surface, the spoiler 2 protruding outward. From this, increase the quantity of vortex piece 2 around a suction section of thick bamboo 3, further strengthen the vortex of vortex piece 2 and subtract and dash the effect, reduce the quantity that erodees the hole, improve the stability of marine wind power suction section of thick bamboo basis 100.
