Description

Technical Field

[0001] The present application relates to the technical field of wind power foundation displacement control, and in particular to a device and method for controlling the lateral displacement of a wind power pile foundation in a port area. Background Art

[0002] In order to achieve zero-carbon terminals, more and more wind power projects are being built in port areas. The wind power foundation is greatly affected by the additional stress of the surrounding dock yard. The pile foundation often undergoes large lateral deformation, causing the tower to tilt and the wind turbine to shut down. In severe cases, the pile foundation may be sheared off, or even cause the wind power to collapse. Frequent loading and unloading of goods on the dock yard causes a large range of magnitude changes in the additional stress of the stacking load, which poses a more serious threat to the safety of wind power built near the yard.

[0003] In order to deal with the impact of this additional stress from the pile load, on the one hand, the stiffness of the foundation of the structure can be increased to resist it, and on the other hand, a pile foundation or wall with greater stiffness needs to be built to block the additional stress from the pile load to reduce the lateral displacement of the pile foundation of the engineering structure. Both methods are very expensive and cannot actively deal with the impact of variable loads from large-scale yard stacking. Summary of the invention

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0034] At present, wind turbine pile foundations in port areas are easily affected by additional stress from pile loads. The existing response methods generally resist this by increasing the foundation stiffness of the structure, or by building a stiffer pile foundation or wall to passively block the additional stress from pile loads, thereby reducing the lateral displacement of the pile foundation of the engineering structure. Both methods are very expensive and cannot cope with the impact of variable loads from large-scale yard stacking.

[0035] In response to the above technical problems, the embodiments of the present application provide a device and method for controlling the lateral displacement of wind turbine pile foundations in port areas. While playing the passive barrier role of the isolation wall against the additional stress of the pile load, it can also play the role of an anchor wall. By dynamically adjusting the tension of the pull rod, it helps to actively control the lateral displacement of the pile foundation of the engineering structure.

[0036] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0037] Figure 1 This is a schematic diagram of the structure of a lateral displacement control device for a wind power pile foundation in a port area provided in an embodiment of the present application. Figure 1 As shown, the lateral displacement control device for the wind turbine pile foundation in the port area includes a wind turbine pile foundation 5, a wind turbine cap 4, an isolation anchor wall 6, a wind turbine foundation inclinometer tube 10, an isolation anchor wall inclinometer tube 11, a displacement adjustment component and a sensor component. The isolation anchor wall 6 is arranged corresponding to the yard stack 1; wherein the yard stack 1 is arranged on the yard ground 2, the isolation anchor wall 6 and the yard stack 1 are offset in the horizontal direction, and the isolation anchor wall 6 is arranged below the yard ground 1; the wind turbine cap 4 is arranged below the yard ground 2, the wind turbine pile foundation 5 is arranged at the lower end of the wind turbine cap 4, and the displacement adjustment component is arranged between the isolation anchor wall 6 and the wind turbine cap 4, for adjusting the lateral displacement of the wind turbine cap 4; the sensor component includes an earth pressure gauge 12, a pore water pressure gauge 13, a static level 14 and a fixed inclinometer 19 (see Figure 2 ); wherein the earth pressure gauge 12 is arranged on the left side of the isolation anchor wall 6, the pore water pressure gauge 13 is arranged below the yard ground 2 and directly below the yard stack 1, and the fixed inclinometer 19 is arranged in multiple numbers, such as Figure 2 As shown, a fixed inclinometer 19 is respectively arranged in the wind power foundation inclinometer tube 10 and the isolation anchor wall inclinometer tube 11, and the wind power foundation inclinometer tube 10 and the isolation anchor wall inclinometer tube 11 are respectively arranged vertically below the yard ground 2 corresponding to the wind power pile foundation 5 and the isolation anchor wall 6.

[0038] It should be noted that the fixed inclinometer 19 is respectively provided in the wind power foundation inclinometer tube 10 and the isolation anchor wall inclinometer tube 11, and a plurality of the wind power foundation inclinometer tube 10 and the isolation anchor wall inclinometer tube 11 can be provided according to the use requirements, and the vertical interval between two adjacent fixed inclinometers 19 in the same tube generally varies between 1m and 5m.

[0039] In this embodiment, the lateral displacement control device of the wind power pile foundation in the port area is used to cope with the influence of variable loads of large-scale yard stacks. Specifically, the isolation anchor wall 6 is used to block the additional stress of the load, that is, the load changes within a certain range can be blocked by the isolation anchor wall 6. The soil pressure gauge 12 and the pore water pressure gauge 13 are started in real time during the actual implementation process, and are used to monitor the data stream in real time. The data stream includes soil pressure and pore water pressure. When the data stream obtained by the soil pressure gauge 12 and the pore water pressure gauge 13 shows that the soil pressure and pore water pressure show an increasing trend or a decreasing trend over time, it means that the yard stack 1 is being loaded or unloaded. In this case, it indicates that the load has changed. The fixed inclinometer 19 in the isolation anchor wall inclinometer tube 11 can be used to determine whether the additional stress of the load generated by the current changing load can be blocked by the isolation anchor wall 6. If the fixed inclinometer 19 in the isolation anchor wall inclinometer tube 11 If the fixed inclinometer 19 in the isolation anchor wall inclinometer tube 11 shows that the isolation anchor wall inclinometer tube 11 is not tilted, it means that the additional stress of the pile load caused by the current changing load can be blocked by the isolation anchor wall 6. If the fixed inclinometer 19 in the isolation anchor wall inclinometer tube 11 shows that the isolation anchor wall inclinometer tube 11 is tilted, such as tilting to the right or left, it means that the additional stress of the pile load caused by the loading or unloading amount of the stack 1 in the yard can no longer be blocked by the isolation anchor wall 6. Further obtain the signal data of the fixed inclinometer 19 in the wind turbine foundation inclinometer tube 10. If the fixed inclinometer 19 in the wind turbine foundation inclinometer tube 10 shows that the wind turbine foundation inclinometer tube 10 is not tilted, then It indicates that the additional stress of the pile load generated by the current changing load has not reached the strength to affect the balance of the wind turbine foundation 4. If the fixed inclinometer 19 in the wind turbine foundation inclinometer tube 10 shows that the wind turbine foundation inclinometer tube 10 is tilted, it indicates that the additional stress of the pile load generated by the current changing load has reached the strength to affect the balance of the wind turbine foundation 4. Further obtain the signal data of the static level 14. If the reading of the static level 14 shows that the wind turbine foundation 4 is still in a horizontal state, it means that the additional stress of the pile load generated by the current changing load has not affected the wind turbine foundation 4. If the reading of the static level 14 shows that the wind turbine foundation 4 is not in a horizontal state, it means that the additional stress of the pile load generated by the current changing load has not affected the wind turbine foundation 4. If the wind turbine foundation 4 is in a horizontal state, it means that the additional stress of the stacking generated by the current changing load has affected the wind turbine foundation 4, and it can be basically determined that the horizontal state change of the wind turbine foundation 4 is caused by the lateral thrust change caused by the load change of the yard stack 1. At this time, the displacement adjustment component can be started to control the displacement of the wind turbine foundation 4 by tightening or loosening the displacement adjustment component (for example, when the load increases, the wind turbine foundation 4 tilts to the right, then the displacement adjustment component is tightened to provide a left torque to the wind turbine foundation 4 to maintain its equilibrium state), so that the wind turbine foundation 4 is in a horizontal state, thereby being able to accurately cope with the impact of a large range of yard stacking changes.

[0040] In some embodiments, Figure 3 This is a schematic diagram of the structure of the displacement assembly provided in the embodiment of the present application. Figure 3 As shown, the displacement adjustment assembly includes a horizontal tie rod 7, a tension adjuster 8 and a power unit. The isolation anchor wall 6 and the wind turbine foundation 5 are connected via the horizontal tie rod 7. The outer side of the horizontal tie rod 7 is provided with a horizontal tie rod thread 7-1. Figure 4 A schematic diagram of the structure of the tension regulator provided in the embodiment of the present application is shown in FIG. Figure 4 As shown, the tension regulator 8 is arranged on the horizontal pull rod 7, and tension regulating end portions 8-1 are arranged at both ends of the tension regulator 8, and tension regulator threads 8-2 are arranged inside, and the tension regulator threads 8-2 are connected to the horizontal pull rod 7 through the horizontal pull rod threads 7-1; the power unit is connected to the tension regulator 8 to drive the tension regulator 8 to rotate, so that the horizontal pull rod 7 moves horizontally (i.e. shortens or lengthens), thereby realizing the adjustment of the lateral displacement of the wind turbine foundation 5.

[0041] In this embodiment, a specific structural example of the displacement adjustment component is given. Among them, the tension adjustment end portions 8-1 set at both ends of the tension adjuster 8 penetrate the tension adjuster 8 as a whole, and the horizontal pull rod 7 cooperates with the tension adjuster thread 8-2 set inside the tension adjustment end portion 8-1 through the horizontal pull rod thread 7-1 set on the outside thereof, so that the tension adjuster 8 is set on the horizontal pull rod 7. Under the action of the power unit, the tension adjuster 8 can be rotated, thereby causing the horizontal pull rod 7 to move horizontally (i.e. shorten or lengthen), thereby controlling the displacement of the wind turbine foundation 4. For example, when the tension adjuster 8 rotates clockwise, the total length of the horizontal pull rod 7 is shortened, which can correct the right-side tilt of the wind turbine foundation 4. When the tension adjuster 8 rotates counterclockwise, the total length of the horizontal pull rod 7 is extended, which can correct the left-side tilt of the wind turbine foundation 4.

[0042] In some embodiments, Figure 3 As shown, the power unit includes an adjusting motor 15, a motor connecting rod 16, a motor power output head 17 and a power transmission belt 18; wherein, the output end of the adjusting motor 15 is coaxially connected to one end of the motor connecting rod 16, the other end of the motor connecting rod 16 is connected to the motor power output head 17, and the motor power output head 17 is connected to the tension regulator 8 through the power transmission belt 18.

[0043] In this embodiment, the specific structure of the power unit is illustrated. The regulating motor 15 is a motor that can realize forward and reverse rotation. Through different rotation directions, the tension regulator 8 can rotate clockwise and counterclockwise. When the regulating motor 15 is working, the motor power output head 17 is driven to rotate through the motor connecting rod 16. The rotating motor power output head 17 further drives the tension regulator 8 to rotate through the power transmission belt 18, thereby realizing the driving of the tension regulator 8.

[0044] In some embodiments, Figure 1As shown, the sensor assembly also includes a dynamometer 9 , which is disposed on the horizontal pull rod 7 .

[0045] In this embodiment, the tension meter 9 can be used to collect the tension data of the horizontal pull rod 7 during a displacement control process. In actual implementation, based on the tension data collected in real time by the tension meter 9 and in combination with the set tension change threshold, the transmission of the horizontal pull rod 7 can be stopped when the tension change threshold is exceeded to avoid over-adjustment. For example, the tension change threshold is set to a N / s. If the change value of the tension data exceeds a, it means that the tension provided at one time is too large, and the displacement control of the wind turbine foundation 4 is not stable enough. At this time, the speed of the regulating motor 15 can be reduced to ensure the stability of the displacement adjustment.

[0046] In some embodiments, Figure 1 As shown, the upper end of the wind turbine support 5 is connected to the wind turbine tower 3 .

[0047] In some embodiments, the lateral displacement control device for the port area wind turbine pile foundation also includes a controller, the signal output end of the sensor assembly is connected to the signal input end of the controller, and the signal output end of the controller is connected to the signal input end of the displacement sensor assembly; the controller is used to: obtain the readings of the pore water pressure gauge, the earth pressure gauge and the fixed inclinometer, if the readings of the pore water pressure gauge and the earth pressure gauge both show an increasing or decreasing trend and the reading of the fixed inclinometer located in the isolation anchor wall inclinometer tube shows that the isolation anchor wall inclinometer tube is deformed to the right or left, then it is determined that the yard stack has started to be loaded or unloaded; obtain the reading of the static level, if the reading of the fixed inclinometer located in the wind turbine foundation inclinometer tube shows that the wind turbine foundation inclinometer tube is deformed to the right or left and the reading of the static level shows that the wind turbine foundation is tilted to the right or left, then the displacement sensor assembly is controlled to be tensioned or relaxed to cause the wind turbine foundation to displace to the left or right until the reading of the static level shows that the wind turbine foundation foundation is restored to the level.

The present application provides a method for controlling the lateral displacement of a wind power pile foundation in a port area, based on a device for controlling the lateral displacement of a wind power pile foundation in a port area in any of the above embodiments, such as Figure 5 As shown, the method includes:

[0049] S1. Obtain the readings of the pore water pressure gauge, earth pressure gauge and fixed inclinometer. If the readings of the pore water pressure gauge and earth pressure gauge show an increasing or decreasing trend and the reading of the fixed inclinometer located at the isolation anchor wall inclinometer tube shows that the isolation anchor wall inclinometer tube is deformed to the right or left, it is determined that the stockpile in the yard has started to be loaded or unloaded;

[0050] S2. Obtain the reading of the static level. If the reading of the fixed inclinometer located in the inclinometer tube of the wind turbine foundation shows that the inclinometer tube of the wind turbine foundation is deformed to the right or left and the reading of the static level shows that the wind turbine foundation is tilted to the right or left, then control the displacement sensor assembly to be tensioned or relaxed to displace the wind turbine foundation to the left or right, until the reading of the static level shows that the wind turbine foundation is restored to the level.

[0051] In some embodiments, the structure of the lateral displacement control device for the wind power pile foundation in the port area used in the method is as follows: Figures 1 to 4 As shown, the device includes a yard ground 2 behind the dock, with a yard stack 1 and a wind turbine tower 3 on it, a pore water pressure gauge 13 is arranged under the yard stack 1, an isolation anchor wall 6 is built below the slope angle, an earth pressure gauge 12 is arranged on the side, and an isolation anchor wall inclinometer tube 11 is arranged on the other side, and a fixed inclinometer 19 is arranged inside, the isolation anchor wall 6 is connected to the wind turbine cap 4 through a horizontal tie rod 7, and a tension regulator 8 and a tension gauge 9 are arranged on the horizontal tie rod 7, and tension regulator ends 8 are provided at both ends. Part 8-1, with a tension regulator thread 8-2 inside, connected to the horizontal pull rod 7 through the horizontal pull rod thread 7-1, below the wind turbine tower 3 is the wind turbine foundation 4, below the wind turbine foundation 4 is a wind turbine pile foundation 5, a wind turbine foundation inclinometer tube 10 is arranged on the side, a fixed inclinometer 19 is arranged inside, a static level 14 is arranged on the wind turbine foundation 4, the regulating motor 15 is connected to the motor power output head 17 through the motor connecting rod 16, and the torque is transmitted between the motor and the tension regulator 8 through the power transmission belt 18.

[0052] In the lateral displacement control method of the port area wind turbine pile foundation, when the yard stack 1 is in a state of loading or unloading, the impact it has on the wind turbine cap 4 may be a tilt to the right or left. However, regardless of whether the yard stack 1 is in a state of loading or unloading, the displacement control principle of the wind turbine cap 4 is basically the same, and the only difference is the direction. In order to specifically describe the displacement control principle of the wind turbine cap 4 by this method, this embodiment provides a flow chart of the lateral displacement control method of the port area wind turbine pile foundation when the yard stack 1 is in a loaded state. Figure 6 FIG. 1 is a flow chart of a method for controlling lateral displacement of a wind power pile foundation in a port area provided in an embodiment of the present application. Figure 2 , the method specifically comprises:

[0053] Step S61, setting the dynamometer reading to 0.

[0054] Step S62, real-time acquisition of the readings of the pore water pressure gauge and the soil pressure gauge, and calculation of the change values ​​△F1 and △F2 of the pore water pressure gauge and the soil pressure gauge; wherein △F1=F t1 -F t1-1 , △F2=F t2 -F t2-1 , Ft1 is the pore water pressure gauge reading at the current moment, F t1-1 is the pore water pressure gauge reading at the last moment, F t2 is the earth pressure gauge reading at the current moment, F t2-1 is the earth pressure gauge reading at the last moment.

[0055] Step S63, determine whether the conditions: ΔF1>0, ΔF2>0 are met; if so, execute step S64, if not, return to step S61.

[0056] Step S64, obtaining the current and previous readings L of the fixed inclinometer in the isolation anchor wall inclinometer tube t1 and L t1-1 .

[0057] Step S65, determine whether: L t1 ≠L t1-1 ; If so, it means that the inclinometer tube of the isolation anchor wall has begun to tilt relative to the previous state, indicating that the additional stress generated by the load of the stockpile has penetrated the barrier of the isolation anchor wall. At this time, execute step S66. If not, it means that the state of the inclinometer tube of the isolation anchor wall has not changed, and return to step S62 to continuously monitor the loading state of the stockpile by obtaining the readings of the pore water pressure gauge and the earth pressure gauge in real time.

[0058] Step S66, obtaining the current and previous readings of the fixed inclinometer in the wind power foundation inclinometer tube L t2 and L t2-1 .

[0059] Step S67, determine whether: L t2 ≠L t2-1 ; If so, it means that the additional stress generated by the load of the stockpile and the stockpile is about to affect the wind turbine foundation, and step S68 is executed at this time; if not, it means that the additional stress generated by the load of the stockpile and the stockpile has not yet affected the wind turbine foundation, return to step S64, and further determine the inclination state of the isolation anchor wall inclinometer tube through step S65.

[0060] Step S68, obtaining the current and previous readings of the static level F t and F t-1 .

[0061] Step S69, determine whether: F t ≠F t-1If yes, it means the position of the wind turbine foundation has changed, and step S70 is executed. If no, it means the position of the wind turbine foundation has not changed, and step S66 is returned. It should be noted that under normal circumstances, when the wind turbine foundation is in the ideal position, the reading of the static level is zero.

[0062] Step S70, control the tension regulator to start tensioning until the reading of the static level is zero, at which point it indicates that the wind turbine foundation has recovered to a horizontal level, and the displacement control ends.
