Problems solved by technology

[0002] After being transported by barge to the destination, the offshore wind turbine foundation needs to be hoisted and launched. However, due to various reasons such as construction technology and site environment, the foundation will not always maintain balance during the sinking process, and may incline. If the inclination angle is too large Large, and not adjusted in time, as the sinking depth increases, the difficulty of leveling will also increase. In severe cases, it will cause engineering accidents such as foundation overturning during the sinking process, which greatly affects the safety of construction

Embodiment 1

[0038] Please refer to Figure 1-4 , figure 1 It is a schematic structural diagram of a specific embodiment of the attitude feed control system for the fan foundation sinking process provided by the present invention, figure 2 It is a structural schematic diagram of a specific implementation of the fan foundation, image 3 for figure 2 Schematic diagram of the structure of the fan foundation in the tilted state, Figure 4 Schematic diagram for the tilting of the wind turbine foundation.

[0039] Such as figure 2 , image 3 As shown, the wind turbine foundation 1 may be inclined during the installation process, and the specific inclination can be referred to Figure 4 : In the original state, a Cartesian coordinate system is constructed based on a certain point of the fan foundation 1, where the planes of the x-axis and y-axis are horizontal planes, and the direction of the z-axis is the vertical direction. Generally speaking, the direction of the z-axis represents the...

Embodiment 2

[0062] Please refer to Figure 5 , Figure 5 It is a flow chart of a specific embodiment of the attitude feed control method during the foundation sinking process of the fan provided by the present invention.

[0063] Such as Figure 5 As shown, the present invention also provides an attitude feed control method for the sinking process of the fan foundation, including:

[0064] Step S1, obtaining the first inclination angle α and the second inclination angle β of the wind turbine foundation 1 in two perpendicular reference planes;

[0065] Step S2, calculate the inclination angle θ of the wind turbine foundation 1 by the following formula;

[0066]

[0067] Step S3, compare whether the inclination angle θ is greater than the first preset value, if so, perform the following step S4;

[0068] Step S4, adjusting the posture of the wind turbine foundation 1 .

[0069] With this scheme, the attitude feed control method provided by the present invention can obtain the first ...

Abstract

The invention provides a posture feed control system and method for a fan foundation sinking process. The posture feed control system for the fan foundation sinking process comprises a data acquisition module, a calculation module, a judgment module and a posture adjustment module, wherein the data acquisition module is installed on a fan foundation and used for monitoring a first inclination angle alpha and a second inclination angle beta of the fan foundation in two perpendicular reference planes; the calculation module is in signal connection with the data acquisition module and is used forreceiving the first inclination angle alpha and the second inclination angle beta and calculating a basic inclination angle theta of the fan foundation according to the first inclination angle alphaand the second inclination angle beta; the judgment module is in signal connection with the calculation module in signal and used for receiving the inclination angle theta and determining whether theinclination angle theta exceeds a first preset value or not; and the posture adjustment module is in signal connection with the judgment module and is used for adjusting the posture of the fan foundation when the inclination angle theta exceeds the first preset value. The posture feed control system can realize the self-judgment and self-adjustment of the inclination status of the fan foundation,thereby ensuring safety.

Description

technical field [0001] The invention relates to the technical field of wind turbine foundations, in particular to an attitude feed control system and an attitude feed control method during the sinking process of the wind turbine foundation. Background technique [0002] After being transported by barge to the destination, the offshore wind turbine foundation needs to be hoisted and launched. However, due to various reasons such as construction technology and site environment, the foundation will not always maintain balance during the sinking process, and may incline. If the inclination angle is too large If it is large, and if it is not adjusted in time, as the sinking depth increases, the difficulty of leveling will also increase. In severe cases, engineering accidents such as foundation overturning will be caused during the sinking process, which will greatly affect the safety of construction. [0003] Therefore, how to provide a solution to overcome the above defects is s...
