Description

Technical Field

[0001] The present invention relates to the technical field of marine wind power piles, and in particular to a method for precisely docking marine wind power pile barrels based on multi-component collaboration. Background Art

[0002] With the growing global demand for clean energy, offshore wind power, as a highly promising form of clean energy, has experienced rapid growth in recent years. Compared to onshore wind power, offshore wind power boasts more stable and robust wind resources, effectively improving the efficiency and capacity of wind power generation. Furthermore, offshore wind power does not occupy land space, avoiding conflicts with other land use methods. This advantage is particularly significant in regions with scarce land resources.

[0003] In offshore wind power facilities, piles serve as key foundational components supporting wind turbines. The accuracy and stability of their installation directly impact the operational safety and power generation efficiency of the entire wind power system. Currently, traditional methods for docking offshore wind turbine piles have numerous drawbacks. For positioning, many rely on manual experience and simple measurement tools, making it difficult to achieve high-precision positioning. For example, common methods rely on equipment such as theodolites for measurement and positioning. In complex marine environments, affected by waves, winds, and measurement errors, the docking deviations between piles are often large. This not only increases the difficulty of subsequent commissioning and maintenance, but may also reduce the service life of the pile structure due to uneven force. Furthermore, in terms of construction efficiency, traditional docking methods are cumbersome and require a significant amount of manpower and time during construction. This severely hinders construction progress, significantly increasing project construction costs and time, and hindering the achievement of accurate and rapid docking. In light of this, we propose a precise docking method for offshore wind turbine piles based on multi-component collaboration. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for precise docking of offshore wind power piles based on multi-component collaboration to solve the defects mentioned in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A method for precise docking of offshore wind power piles based on multi-component collaboration includes the following steps:

[0007] 1. Initial Positioning Phase

[0008] S1. The pile is embedded and fixed in the corresponding position. The mounting frame is hoisted above the pile. The positioning blocks arranged in a circular pattern with equal spacing on the bottom surface of the mounting frame are aligned with the first clamping gaps arranged in a circular pattern with equal spacing on the upper surface of the pile. The positioning protrusions are aligned with the second clamping gaps between the positioning blocks and inserted stably to achieve precise insertion and fit, thereby completing the preliminary positioning of the mounting frame relative to the pile.

[0009] II. Initial reinforcement stage

[0010] S2. After completing the preliminary positioning, use fastening bolts to fix between the support ring and the fixing ring to connect the pile barrel and the mounting rack; multiple first support ribs arranged at equal intervals in a ring between the support ring and the pile barrel, and multiple second support ribs arranged at equal intervals in a ring between the fixing ring and the mounting rack are used for compressive support and protection;

[0011] III. Re-positioning and reinforcement stage

[0012] S3. Insert a tool through the exposed hole on the annular side of the mounting rack for operation, rotate the rotating shaft in the support box, and the convex column, stud, vertical rod and knob at the top of the rotating shaft facilitate the operator to apply force; the rotation of the rotating shaft drives the gear fixed on it to rotate. Since the gear meshes with two racks, and the racks slide in the sliding holes on the front and rear cavity walls of the support box, the rotation of the gear makes the two racks move in opposite directions, driving the positioning plug rod at the end to move. The positioning plug rod is inserted into the rectangular jack in the reinforcement plate on the mounting rack to realize the secondary positioning and reinforcement of the mounting rack and the pile barrel;

[0013] IV. Limiting and fixing stage

[0014] S4. After the positioning plug rod is stably inserted into the rectangular jack for limiting, hold the vertical rod and the knob to ensure that the vertical rod and the knob no longer rotate. Then rotate the threaded sleeve. After the threaded sleeve rotates, it will move downward synchronously, driving the lower pressing and sealing disc to press against the upper surface of the support box. At this time, the threaded sleeve can appropriately press against the rotating shaft and the stud parts, so that the vertical rod will not rotate easily.

[0015] In the technical solution of the present invention, it includes a pile barrel adopting the precise docking method of the offshore wind power pile barrel based on multi-component cooperation.

Slide holes communicating with the outside are arranged on the front and rear side walls of the supporting box. A rack is slidably connected in the slide hole. The end of the rack located outside the supporting box is fixedly installed with a positioning insertion rod. The positioning insertion rod is in plug-in fit with the corresponding rectangular jack. A rotating shaft is rotatably connected at the center position of the supporting box. A gear is fixedly installed on the rotating shaft. The gear is located between the two racks and meshes with the two racks.

[0017] In the technical solution of the present invention, the cross-sections of the positioning convex block and the positioning block are both isosceles trapezoids. The size of the positioning block is adapted to the size of the first clamping gap. The size of the positioning convex block is adapted to the size of the second clamping gap.

A plurality of second support ribs arranged in an annular and equally spaced manner are fixedly installed between the upper surface of the fixing ring and the mounting frame.

[0020] In the technical solution of the present invention, two symmetrically arranged exposure holes are arranged on the annular side surface of the mounting frame. The exposure holes are arranged along the height direction of the mounting frame. The exposure holes are used for the insertion operation of tools.

[0021] In the technical solution of the present invention, shaft holes are arranged on the top wall and the bottom wall of the supporting box. The rotating shaft is arranged vertically in the shaft holes. Two symmetrically arranged bearings are fixedly installed on the rotating shaft.

[0044] Please refer to Figures 1-9 , a precise docking method for an offshore wind power pile barrel based on multi-component collaboration of the present invention, comprising the following steps:

[0045] I. Initial positioning stage

[0046] S1. Pre-bury and fix the pile barrel 1 at the corresponding position at sea. Lift the mounting frame 2 to the upper part of the pile barrel 1 by using an external lifting tool, so that the positioning blocks 20 arranged at equal intervals in a ring shape on the bottom surface of the mounting frame 2 are aligned with the first clamping gaps 111 arranged at equal intervals in a ring shape on the upper surface of the pile barrel 1. At the same time, the positioning protrusions 11 are aligned with the second clamping gaps 21 between the positioning blocks 20 and stably inserted. Since the cross-sections of the positioning protrusions 11 and the positioning blocks 20 are both isosceles trapezoids, the downward insertion is smoother, realizing precise insertion and matching, and completing the preliminary positioning of the mounting frame 2 relative to the pile barrel 1;

[0047] II. Initial reinforcement stage

[0048] S2. After completing the preliminary positioning, fix the pile barrel 1 and the mounting frame 2 by using fastening bolts between the support ring 10 and the fixing ring 23; multiple first support ribs 13 arranged at equal intervals in a ring shape between the support ring 10 and the pile barrel 1, and multiple second support ribs 24 arranged at equal intervals in a ring shape between the fixing ring 23 and the mounting frame 2 are used for compressive support and protection to enhance the compressive performance;

[0049] III. Re-positioning and reinforcement stage

[0050] S3. Insert a tool through the exposed holes 22 on the circumferential side of the mounting frame 2 for operation. Rotate the rotating shaft 33 in the support box 3. The convex column 36, stud 361, vertical rod 37 and knob 371 at the top of the rotating shaft 33 facilitate the operator to apply force; the rotation of the rotating shaft 33 drives the gear 34 fixed on it to rotate. Since the gear 34 meshes with the two racks 32, and the racks 32 slide in the sliding holes 31 on the front and rear side walls of the support box 3, the rotation of the gear 34 makes the two racks 32 move in opposite directions, driving the positioning plug rod 39 at the end to move. After the positioning plug rod 39 slides out, it is inserted into the rectangular jack 251 in the reinforcement plate 25 on the mounting frame 2, realizing the secondary positioning and reinforcement of the mounting frame 2 and the pile barrel 1;

[0051] IV. Limit fixing stage

[0052] S4. After the positioning plug rod 39 is stably inserted into the rectangular jack 251 for limiting, hold the vertical rod 37 and the knob 371 to ensure that the vertical rod 37 and the knob 371 no longer rotate. Then rotate the threaded sleeve 381. After the threaded sleeve 381 rotates, it will move downward synchronously, driving the lower pressing and sealing disc 382 to abut against the upper surface of the support box 3. After the lower pressing and sealing disc 382 abuts, due to the precise threaded connection between the threaded sleeve 381 and the stud 361 and having a certain meshing force, and at the same time, the upper pressing sleeve 38 abuts against the top surface of the stud 361. At this time, the threaded sleeve 381 and the upper pressing sleeve 38 can also appropriately press against the shaft 33 and the stud 361 parts, so that the vertical rod 37 will not rotate easily, further ensuring that the shaft 33 will not rotate easily.

[0053] In this embodiment, it includes the pile barrel 1 adopting the precise docking method of the offshore wind power pile barrel based on multi-component cooperation. A plurality of positioning bumps 11 arranged in an annular and equally spaced manner are fixedly installed on the upper surface of the pile barrel 1. A first clamping gap 111 is provided between two adjacent positioning bumps 11. An installation frame 2 is arranged above the pile barrel 1. A plurality of positioning blocks 20 arranged in an annular and equally spaced manner are fixedly installed on the bottom surface of the installation frame 2. A second clamping gap 21 is provided between two adjacent positioning blocks 20. The positioning blocks 20 are in plug-in fit with the first clamping gap 111, and the positioning bumps 11 are in plug-in fit with the second clamping gap 21. The cross-sections of the positioning bumps 11 and the positioning blocks 20 are both in the shape of an isosceles trapezoid. The size of the positioning blocks 20 is adapted to the size of the first clamping gap 111, and the size of the positioning bumps 11 is adapted to the size of the second clamping gap 21. This design uses the adapted structure of the isosceles trapezoid shape, greatly improving the accuracy of the initial positioning when the pile barrel 1 is docked with the installation frame 2, effectively shortening the docking time, and improving the docking efficiency.

[0054] Specifically, a support ring 10 is fixedly installed on the top cylinder of the pile barrel 1, and a fixing ring 23 is fixedly installed on the bottom cylinder of the installation frame 2. The support ring 10 and the fixing ring 23 are fixedly connected by a plurality of fastening bolts, forming a stable connection foundation between the pile barrel 1 and the installation frame 2; a plurality of first support ribs 13 arranged in an annular and equally spaced manner are fixedly installed between the bottom surface of the support ring 10 and the pile barrel 1, and a plurality of second support ribs 24 arranged in an annular and equally spaced manner are fixedly installed between the upper surface of the fixing ring 23 and the installation frame 2, further enhancing the structural strength of the connection part, ensuring the stability of the connection between the pile barrel 1 and the installation frame 2, and improving the reliability of the overall structure in the marine environment.

[0055] Further, there are two symmetrically arranged exposure holes 22 on the annular side surface of the mounting frame 2, and the exposure holes 22 are arranged along the height direction of the mounting frame 2. The exposure holes 22 are used for the insertion operation of tools, providing a convenient tool insertion channel for the operator and making the subsequent operation on the internal structure easier; on the annular side surface of the mounting frame 2, two symmetrically arranged reinforcing plates 25 are fixedly installed. A rectangular jack 251 communicating with the inside of the mounting frame 2 is arranged in the reinforcing plate 25. At the center position of the top surface of the pile cylinder 1, a support cushion block 12 is fixedly installed, providing a stable support foundation for the internal transmission structure; on the upper surface of the support cushion block 12, a support box 3 is rotatably connected. Slide holes 31 communicating with the outside are arranged on the front and rear side walls of the support box 3. A rack 32 is slidably connected in the slide holes 31. At the end of the rack 32 located outside the support box 3, a positioning plug 39 is fixedly installed. The positioning plug 39 is in plug-in fit with the corresponding rectangular jack 251. A rotating shaft 33 is rotatably connected at the center position of the support box 3. A gear 34 is fixedly installed on the rotating shaft 33. The gear 34 is located between the two racks 32 and meshes with the two racks 32, realizing the secondary positioning and reinforcement of the mounting frame 2 and the pile cylinder 1.

[0056] Further, shaft holes 30 are arranged on both the top wall and the bottom wall of the support box 3. The rotating shaft 33 is vertically arranged in the shaft holes 30. Two symmetrically arranged bearings 35 are fixedly installed on the rotating shaft 33. The bearings 35 are fixedly installed on the inner wall of the shaft holes 30, reducing friction and ensuring the smooth rotation of the rotating shaft 33.

[0057] In addition, slide bars 311 arranged along the length direction of the slide holes 31 are arranged on both the upper and lower side walls of the slide holes 31. Chute grooves 321 arranged along the length direction of the rack 32 are arranged on both the top surface and the bottom surface of the rack 32. The slide bars 311 are located in the chute grooves 321 and are slidably connected with the chute grooves 321, playing a good guiding role and ensuring the stability of the movement of the rack 32.

[0058] It should be noted that a convex column 36 is fixedly installed at the top end of the rotating shaft 33. A stud 361 is fixedly installed at the top end of the convex column 36. A vertical rod 37 is fixedly installed at the top end of the stud 361. A knob 371 is fixedly installed at the top end of the vertical rod 37, facilitating the operator to apply force to rotate the rotating shaft 33.

[0059] It should be noted that a threaded sleeve 381 is threadedly connected to the stud 361. The top end of the threaded sleeve 381 is fixedly installed with an upper pressing sleeve 38, and the bottom end of the threaded sleeve 381 is fixedly installed with a lower pressing and sealing disc 382. The lower pressing and sealing disc 382 abuts against the upper surface of the support box 3. The outer diameter of the vertical rod 37 is smaller than the outer diameter of the stud 361. The upper pressing sleeve 38 abuts against the top surface of the stud 361. The upper pressing sleeve 38 is sleeved on the vertical rod 37 and is slidably connected to the vertical rod 37. After the lower pressing and sealing disc 382 is tightened, due to the precise threaded connection between the threaded sleeve 381 and the stud 361 and having a certain meshing force, at the same time, the upper pressing sleeve 38 abuts against the top surface of the stud 361. At this time, the threaded sleeve 381 and the upper pressing sleeve 38 can also appropriately tighten the parts of the rotating shaft 33 and the stud 361, so that the vertical rod 37 will not rotate easily, achieving the effect of preventing the vertical rod 37 from loosening and rotating randomly.

[0060] In this embodiment, a frustum-shaped end 391 is fixedly installed at the outer end of the positioning insertion rod 39. The outer diameter of the frustum-shaped end 391 decreases sequentially from back to front, which is convenient for inserting into the rectangular jack 251, improving the convenience and accuracy of the insertion operation of the positioning insertion rod 39.
