A multifunctional heavy-duty support device for wind power monopile and its control method

Abstract

The invention relates to a multifunctional heavy-duty supporting device for wind power single piles, which includes a base, a driving assembly placed on the base, and a supporting seat placed above the driving assembly. Adjusting seats are respectively provided on both sides of the upper end of the supporting seat, and the two There are circular arc surfaces on the adjustment seats, and the arc surfaces on the two adjustment seats form a notch for the single pile of wind power to be snapped in. The center position of the support seat is a rotating assembly that can be lifted up and down, and the adjustment seat has a support assembly. The two supporting components are arranged axisymmetrically with the rotating component as the center; when the rotating component falls below the upper end surface of the support seat, the wind power monopile is stuck in the notch and is supported and fixed by the supporting components on both sides; when the rotating component rises to the support When the seat is above the end surface, the wind power monopile forms an integral rotation with the support assembly as the rotating assembly rotates. The invention has the advantages of ensuring the surface quality of the wind power single pile while ensuring the rotation stability of the wind power single pile.

Description

Technical field: [0001] The invention relates to the field of wind power monopile, in particular to a multifunctional heavy-duty supporting device for wind power monopile and a control method thereof. Background technique: [0002] Offshore wind power is an important new energy technology. The foundation design and construction of offshore wind turbines is one of the key technologies in the construction of offshore wind farms. Wind power monopile is the long cantilever structure of offshore wind turbines. Under the repeated action of wave and current loads, it is easy to produce Larger fatigue cumulative damage, with the continuous increase of the single unit capacity of offshore wind turbines, in order to adapt to complex marine hydrogeology and other natural conditions, and at the same time to meet the strict requirements of the foundation deformation for the normal operation of the upper wind turbine equipment, the single pile foundation The pile diameter continues to inc...

AI Technical Summary

Problems solved by technology

[0003] At present, the support equipment used for wind power monopile is equipped with two rollers on both sides of the lower part of the wind power monopile. The two rollers are rotated by the motor to make the wind power monopile rotate on the support equipment, which is convenient for the closing and welding of wind power monopile. , which has low versatility and cannot meet the bearing requirements of wind power single piles with different diameters, and has the following defects:

[0004] 1. If the wind power monopile does not need to rotate, when only the support function is realized on the supporting equipment, the gravity of the wind power monopile itself is concentrated on the two rollers. Since the force-bearing area of ​​the rollers is small, the rollers have a large impact on the surface of the wind power monopile. The generated pressure is high, which affects the surface quality of the wind power monopile;

[0005] 2. When the wind power single pile rotates, the two rollers rotate to drive the wind power single pile to rotate at a constant speed. However, the rotation synchronization of the two rollers is extremely demanding. Wear marks occur between the pile surfaces. If the speed difference between the two rollers is greater, the wear on the surface of the wind power monopile will be more serious, and even the toppling of the wind power monopile will occur.
