In order to make the technical solution of the present application easier to understand, the following further describes the technical solution of the present application with the direction close to the center line of the pillar 1 being inward and the direction away from the center line of the pillar 1 being outward.

A plurality of spoiler pins 2 aligned in a line along the radial direction of the suction cylinder 3 are defined in a row. One row of turbulence nails 22 are distributed at intervals in the radial direction of the suction cylinder 3, the number of each row of turbulence nails 22 is the same, and a plurality of rows of turbulence nails 22 are distributed at intervals on the top end face of the surrounding upright post 1. The innermost turbulence pin 22 in each row of turbulence pins 22 is different from the innermost turbulence pin 22 in the adjacent row of turbulence pins 22 in distance from the center line of the upright post 1, so that two adjacent turbulence pins 22 in the inner and outer directions are formed and are arranged in a staggered manner in the radial direction of the suction cylinder 3.

For example, one of the rows of turbulence nails 22 is an a row, one row of the turbulence nails 22 adjacent to the a row of the turbulence nails 22 is a B row, the innermost turbulence nail 22 of the a row of the turbulence nails 22 is numbered as a1, the outer portions of the a row of the turbulence nails 22 are sequentially numbered as a2, A3 and a4 …, the innermost turbulence nail 22 of the B row of the turbulence nails 22 is numbered as B1, the outer portions of the B row of the turbulence nails 22 are sequentially numbered as B2, B3 and B4 …, distances from the center lines of the upright posts 1 to the a1 and the B1 are different, distances from the center lines of the upright posts 1 to the a2 and the B2 are also different, and the a row of the turbulence nails 22 and the B row of the turbulence nails 22 are formed to be arranged in a staggered manner in the radial direction of the suction cylinder 3.

Further, in the circumferential direction around the column 11, there are rows C, D, E, F, and the like. A1, B1, C1, D1, E1, F1, etc. may be arranged according to a certain rule, for example, the distances between a1, B1, C1, D1, E1, F1 and the center line of the column 1 are sequentially increased.

Two adjacent spoiler nails 2 are greater than or equal to 0.25d and less than or equal to 3.0d in the circumferential direction around the pillar 1, that is, the distance between a1 and B1 in the circumferential direction is greater than or equal to 0.25d and less than or equal to 3.0d, for example, the distance between a1 and B1 is 0.25d, 0.26d, 0.28d, 0.3d and the like.

It should be noted that, in each row of the spoiler nails 22, two adjacent spoiler nails 22 may be arranged at equal intervals, may also be arranged according to a certain rule, or may be arranged at random intervals. For example, in column A, the spacing between A1 and A2 is one value and the spacing between A2 and A3 is another value, which may or may not be equal.

It should be noted that in other embodiments, the number of the two adjacent rows of spoilers 2 may not be the same. For example, one row is provided with X turbulence pins 2, and the other row is provided with Y turbulence pins 2.

The staggering of two turbulence nails 2 adjacent in the circumferential direction around the upright post 1 is similar to the staggering of two turbulence nails 2 adjacent in the radial direction of the suction barrel 3, and the details are not repeated here. The distance between two adjacent spoiler nails 2 in the radial direction of the suction barrel 3 is greater than or equal to 0.25d and less than or equal to 3.0d, namely the distance between A1 and B1 in the inner and outer directions is greater than or equal to 0.25d and less than or equal to 3.0 d. For example, the pitches of a1 and B1 in the medial-lateral direction are 0.25d, 0.26d, 0.28d, 0.3d, and the like.

From this, can be according to certain law staggered arrangement between a plurality of vortex nails 22, also can arrange at random between a plurality of vortex nails 22, and then form diversified crisscross form on pile foundation 1's surface to can choose for use the vortex nail 22 of different crisscross forms according to the waters of difference, and then more effectual carries out the vortex to the trend, realizes the marine wind power suction section of thick bamboo basis 100's that has the vortex nail diversification.

In some embodiments, the plurality of turbulence nails 2 are divided into a plurality of rows, each row of turbulence nails 2 includes a plurality of turbulence nails 2 arranged at equal intervals in the radial direction of the suction cylinder 3, the plurality of rows of turbulence nails 2 are arranged in the circumferential direction around the column 1, and two adjacent rows of turbulence nails 2 are staggered in the circumferential direction.

A, B, C, D, E, F rows of turbulence nails 2 are arranged on the top end face of the suction barrel 3, and the interval between two adjacent turbulence nails 2 in each row of turbulence nails 2 is equal. The spacing between a1 and a2, the spacing between a2 and A3, the spacing between A3 and a4, etc. are all equal. The multiple rows of turbulence nails 2 are regularly and alternately arranged, the distances from A1, C1 and E1 to the center line of the upright post 1 are first set distances, and the distances from B1, D1 and F1 to the center line of the upright post 1 are second set distances. The first set distance and the second set distance are different, and the interval between a1 and B1, the interval between B1 and C1, the interval between C1 and D1, and the like are equal. From this, the regular equipartition of a plurality of vortex nails 2 is on the outer peripheral face of pile foundation 1 to be convenient for workman's processing vortex nail 2.

In the related art, where the position where the column 1 is connected to the suction tube 3 is where the vortex is mainly formed, the column 1 is subjected to a large impact force of the tidal current.

In some embodiments, the density of turbulators 2 increases towards the column 1.

For example, the closer the distance to the upright post 1, the greater the density of the arrangement of the turbulence nails 2, and therefore, the greater the impact of the tidal current on the area, the greater the density of the arrangement of the turbulence nails 2, so as to improve the turbulence effect of the turbulence nails 2 and enhance the anti-scouring capability of the upright post 1.

In the related art, the offshore wind power suction cylinder foundation 100 having the spoiler pin is mainly disposed in a shallow water area where a tidal current is mainly close to or far from a coastline in 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 opposite to 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 tip end face of the suction tube 3 includes a front face facing the tidal flow direction, a back face opposite to the front face, and two side faces, and the density of the turbulator pins 2 distributed on the front face and the back face is greater than the density of the turbulator pins 2 distributed on the two 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 density of the turbulence pins 2 arranged on the front and back of the top end face of the suction cylinder 3 is greater with respect to the remaining two side faces of the top end face of the suction cylinder 3. For example, the density of turbulator spikes 2 disposed on the front and side surfaces of suction cartridge 3 is 2 times that of the remaining two side surfaces. From this, marine wind power suction section of thick bamboo basis 100 with vortex nail can enough have stronger scour protection ability, can reduce its manufacturing cost again, reduces the manufacturing difficulty.

Alternatively, the density of the turbulators 2 distributed on the front surface may be made smaller than the density of the turbulators 2 distributed on the back 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 spoiler nails 2 arranged on the east and west sides of the tip end face of the suction cylinder 3 is large.

In some embodiments, a part of the turbulator pins 2 has a different size from the rest of the turbulator pins 2, and the turbulator pins 2 having different sizes are alternately arranged on the top end surface of the suction cylinder 3.

The dimensions of the turbulence nail 2 are the length, the width, the height and the like of the turbulence nail 2. The size of vortex nail 2 in the radial direction of a suction section of thick bamboo 3 is the length L of vortex nail 2, and vortex nail 2 is in the width M that encircles the ascending size in circumference of stand 1 for vortex nail 2, and vortex nail 2 is the height of vortex nail 2 in the size of upper and lower direction. On the top end face of the suction cylinder 3, turbulator pins 2 in different positions have different sizes.

From this, through setting up different sizes, increase the irregularity of the vortex nail 2 that sets up, vortex nail 2 when facing trend and horseshoe swirl, can break up the flow law of trend and horseshoe swirl in a better way, change rivers flow direction and velocity of flow to a great extent, the scour protection ability of the marine wind power suction section of thick bamboo basis 100 that has the vortex nail of reinforcing, and make the marine wind power suction section of thick bamboo basis 100 that has the vortex nail of can deal with the trend and the horseshoe swirl of multiple energy gradient, the adaptability of marine wind power suction section of thick bamboo basis 100 that has the vortex nail of reinforcing.

In some embodiments, the size of the spoiler nail 2 in the vertical direction is the height of the spoiler nail 2, and the spoiler nail 2 arranged in the radial direction of the suction cylinder 3 includes a plurality of different heights, and/or the spoiler nail 2 arranged in the circumferential direction around the column 1 includes a plurality of different heights.

For example, as shown in fig. 1, the dimension of the spoiler pin 2 in the up-down direction is the height of the spoiler pin 2, and the heights of the plurality of spoiler pins 2 are regularly or randomly set. Several height arrangements are described below:

first, the plurality of turbulators 2 arranged along the radial direction of the suction barrel 3 include a plurality of different height dimensions, for example, in the radial direction, the heights of the plurality of turbulators 2 increase or decrease sequentially along the direction close to the upright post 1.

Second, a plurality of spoiler nails 2 arranged along the circumference around the pillar 1 include a plurality of different height dimensions, for example, a plurality of spoiler nails 2 are sequentially increased or decreased in height along the direction around the pillar 1.

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

In addition, the heights of the turbulence pins 2 may be randomly distributed.

From this, through setting up different heights, increase the irregularity of the vortex nail 2 that sets up, vortex nail 2 is when facing trend and horseshoe swirl, can break up the law of flow of trend and horseshoe swirl better and break up in disorder, change rivers flow direction and velocity of flow more greatly, the reinforcing has the scour protection ability of the marine wind power suction section of thick bamboo basis 100 of vortex nail, and make the marine wind power suction section of thick bamboo basis 100 that has the vortex nail can deal with the trend and the horseshoe swirl of multiple energy gradient, the adaptability of the marine wind power suction section of thick bamboo basis 100 that has the vortex nail has been strengthened.

In some embodiments, the spoiler nail 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 pin 2 is also provided at the lower end of the pillar 1, and the spoiler pin 2 extends outward in the radial direction of the pillar 1. Therefore, the flow of tide is further disturbed around the upright post 1, the disturbed flow impact reduction effect of the disturbed flow nail 2 is further enhanced, and the anti-scouring capability of the upright post 1 is enhanced.

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

For example, a spoiler pin 2 is provided on a portion of the outer circumferential surface of the suction cylinder 3 near the tip end surface, and the spoiler pin 2 protrudes in a direction away from the outer circumferential surface of the suction cylinder 3 in the radial direction of the suction cylinder 3. From this, increase the quantity of vortex nail 2 around a suction section of thick bamboo 3, further strengthen the vortex of vortex nail 2 and subtract and dash the effect, reduce the quantity that erodees the hole, improve the marine wind power suction section of thick bamboo basis 100's that has the vortex nail stability.

In some embodiments, the dimension of the spoiler nail 2 in the vertical direction is the height of the spoiler nail 2, and the height of the spoiler nail 2 is 0.1m to 0.5 m.

For example, the heights of the spoiler pins 2 are 0.1m, 0.2m, 0.3m, 0.4m, 0.5m, and the like.
