Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power pile foundations, and in particular to a wind power pile foundation leveling device and a leveling method. Background Art

[0002] Under the long-term wind-wave-current coupling load, the offshore wind turbine pile foundation will undergo certain displacement deformation and increase the rotation angle. Although redundancy is reserved during construction, the pile foundation deformation may still exceed the allowable displacement and allowable rotation angle during long-term use, shortening the service life of the offshore wind turbine pile foundation. Therefore, in order to ensure the normal use of the offshore wind turbine pile foundation during the service period and extend the service life of the offshore wind turbine pile foundation, a wind turbine pile foundation leveling device and leveling method are proposed.

[0003] The invention with the authorization announcement number CN207944474U discloses a leveling device for a single pile foundation in an offshore wind power device, wherein the offshore wind power device uses multiple underwater thrusters to simultaneously drive an active drive ring to rotate around its own axis, thereby driving the push rod 2 to rotate around its own axis under the action of the bevel gear, and then driving the push rod to rotate while performing axial feed motion under the influence of the synchronous rotation structure, and finally driving the leveling block to perform linear motion; and the simultaneous movement of multiple leveling blocks will eventually drive the axis of the single pile foundation back to the initial position, thereby achieving the leveling action of the single pile foundation. However, the structure of the above-mentioned leveling device is relatively complex, and can only be used for leveling work after the single pile foundation is tilted. Summary of the invention

[0004] The purpose of the present invention is to solve the defects in the prior art and provide a wind turbine pile foundation leveling device and a leveling method, which can improve the horizontal and vertical bearing capacity of the wind turbine pile foundation and realize the leveling of the wind turbine pile foundation.

[0005] To achieve the above-mentioned object, the present invention provides a wind power pile foundation leveling device, comprising a plurality of telescopic anchors arranged around the wind power pile foundation;

[0006] The telescopic anchor is used to support and level the wind turbine pile foundation, and includes a telescopic component and an anchor head. The telescopic component is used to adjust the length of the telescopic anchor, one end of which is connected to the wind turbine pile foundation, and the other end is connected to the anchor head. The anchor head is used to be fixedly connected to the ground.

[0007] The present invention arranges a plurality of telescopic anchors around the wind turbine pile foundation, wherein the telescopic anchors include a telescopic assembly and an anchor head, wherein the telescopic assembly is connected to the anchor head, wherein the anchor head is obliquely inserted into the ground, and the telescopic assembly is connected to the wind turbine pile foundation. The telescopic anchors can improve the horizontal bearing capacity and the vertical bearing capacity of the wind turbine pile foundation, can support the wind turbine pile foundation, and reduce the inclination of the wind turbine pile foundation.

[0008] When the inclination degree of the wind turbine pile foundation is small, the telescopic anchors arranged in the inclination direction of the wind turbine pile foundation support the wind turbine pile foundation, and the anchor heads arranged on the telescopic anchors away from the inclination direction of the wind turbine pile foundation are connected to the ground, pulling the wind turbine pile foundation to prevent it from further inclination, and leveling is performed through the reaction force provided by the ground soil to prevent the wind turbine pile foundation from becoming unstable.

[0009] When the wind turbine pile foundation is tilted to a large extent, the telescopic anchors set in the tilt direction of the wind turbine pile foundation are extended, and the telescopic anchors away from the tilt direction of the wind turbine pile foundation are shortened, and the wind turbine pile foundation is adjusted to be perpendicular to the ground, thereby increasing the stability of the wind turbine pile foundation, and the moving direction of the wind turbine pile foundation can be freely adjusted by freely selecting the position and angle of the additional telescopic anchors.

There are multiple second connecting rods, each of the first connecting rods is rotatably connected to its corresponding second connecting rod, and the multiple second connecting rods are all slidably connected to the second hoop.

Under the action of the ground soil and the telescopic assembly, the anchor head set on the telescopic anchor away from the tilting direction of the wind turbine pile foundation opens, so that the friction between the anchor head and the ground soil increases, the pull-out resistance of the wind turbine pile foundation is improved, and the wind turbine pile foundation is prevented from continuing to tilt. The first connecting rod is connected to the middle of the second connecting rod, that is, when the anchor head opens, the outermost end of the second connecting rod exceeds the outermost end of the first connecting rod, which can further increase the friction between the ground soil and the anchor head.

[0014] Optionally, a first sliding groove is provided on the first hoop, and a first sliding block matching the first sliding groove is correspondingly provided on the first connecting rod.

[0015] When the anchor head is inserted into the ground, the first connecting rod slides to the upper part of the first sliding groove, so that the anchor head shrinks to the minimum and reduces the installation resistance of the anchor head; when the wind turbine pile foundation tilts, the first connecting rod on the anchor head away from the tilt direction of the wind turbine pile foundation gradually slides to the lower part of the first sliding groove, so that the anchor head opens to the maximum, and the friction between the anchor head and the ground soil increases.

[0016] Optionally, a second sliding groove is provided on the second hoop, and a second sliding block matching the second sliding groove is correspondingly provided on the second connecting rod.

The first support rod and the second support rod are both fixed, and the first sleeve is rotated, so that the distance between the first support rod and the first sleeve remains unchanged, and the distance between the first sleeve and the second support rod changes, thereby adjusting the distance between the first support rod and the second support rod, changing the length of the telescopic assembly, and realizing the length adjustment of the telescopic anchor, and the telescopic assembly is detachable and easy to recycle.

[0022] A certain margin is ensured when the first sleeve and the second support rod are threadedly connected, so as to provide for secondary leveling in case the wind power pile foundation is tilted in the later stage.

In this embodiment, the anchor head 22 is inserted into the ground at an inclination of 45°.

[0055] When the inclination degree of the wind turbine pile foundation 1 is small, the telescopic anchor 2 arranged in the inclination direction of the wind turbine pile foundation 1 supports the wind turbine pile foundation 1, and the anchor head 22 arranged on the telescopic anchor 2 away from the inclination direction of the wind turbine pile foundation 1 is connected to the ground, pulling the wind turbine pile foundation 1 to prevent it from further inclination, and leveling it through the reaction force provided by the ground soil to prevent the wind turbine pile foundation 1 from becoming unstable.

[0064] In this embodiment, the number of the first sliding grooves 222 corresponds to the first connecting rods 223 , and eight groups are provided. The number of the first sliding grooves 222 can be adjusted according to demand.
