Description

Technical Field

[0001] The present invention relates to the technical field of offshore engineering equipment, and particularly to a device for quickly detecting and adjusting the verticality of pile legs of an offshore wind power construction platform. Background Art

[0002] With the continuous growth of the global demand for clean energy, offshore wind power has become an important development direction in the new energy field due to its advantages such as rich resources and no occupation of land space. As a key facility for the installation and maintenance of offshore wind turbines, the verticality of the pile legs of an offshore wind power construction platform directly affects the stability and safety of the platform, and thus is related to the normal operation of the entire wind power project. Under the action of complex offshore environments such as wind, waves, and water currents, the pile legs are extremely prone to inclination during installation and use. Therefore, realizing the quick detection and precise adjustment of the verticality of the pile legs is a key link to ensure the safe and efficient construction of offshore wind power.

[0003] Currently, in the existing technologies for detecting and adjusting the verticality of pile legs of offshore wind power construction platforms, common detection methods include the plumb line method and the laser observation method. The plumb line method judges the verticality by hanging a plumb line and manually comparing the relative positions of the plumb line and the pile legs; the laser observation method uses a laser emitter to emit a laser beam and evaluates the inclination situation by observing the projection position of the laser on the surface of the pile legs. In terms of adjustment, generally, simple mechanical pushing devices or manual auxiliary correction are adopted.

[0004] However, the existing technologies have many problems in actual application scenarios. In harsh offshore environments, the plumb line method and the laser observation method are greatly affected by factors such as wind and wave shaking and light changes, and manual observation is extremely prone to errors, resulting in inaccurate detection results. For example, in strong wind weather, the plumb line will swing with the wind, making it difficult to accurately judge the verticality of the pile legs; laser observation is also affected by light refraction and water mist occlusion, causing data deviation. Therefore, the present invention provides a device for quickly detecting and adjusting the verticality of pile legs of an offshore wind power construction platform to solve the deficiencies existing in the existing technologies.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to the attached Figure 1 - attached Figure 10, an embodiment of the present invention provides a device for quickly detecting and adjusting the verticality of a leg of an offshore wind power construction platform, including: a leg 4, which serves as the main body to be detected; a detection mechanism 1, which is arranged on the outer side of the leg 4 for detecting the leg 4. The detection mechanism 1 includes a base one 101 and a counterweight assembly. Two guide rods 102 are fixedly connected to the top of the base one 101. The top of the guide rod 102 is fixedly connected with an adapter block 103. A guide wheel 104 is rotatably connected to the adjacent sides of the two adapter blocks 103. A sliding sleeve 109 is slidably connected to the outer side of the guide rod 102. Two contact heads 110 are fixedly connected to the adjacent sides of the two sliding sleeves 109. A pressure sensor is arranged inside the mounting box 108. A motor one 105 is installed on the outer side of the base one 101. The output end of the motor one 105 is fixedly connected with a winding rod 106. A pull rope 107 is fixedly connected to the outer side of the winding rod 106. The outer side of the pull rope 107 is in contact with the outer side of the guide wheel 104. One end of the pull rope 107 is fixedly connected to the top of the mounting box 108. The counterweight assembly includes a counterweight block 112 and a connecting strip 115. Two combined plates two 113 are fixedly connected to the top of the counterweight block 112. Two combined plates one 111 are fixedly connected to the bottom of the mounting box 108. Two jacks 114 are respectively opened inside the combined plates one 111 and the combined plates two 113. Two pins 116 are fixedly connected to the outer side of the connecting strip 115. The outer side of the pin 116 is slidably connected to the inner side of the jack 114. A limiting hole 117 is opened inside the pin 116. A limiting strip 118 is slidably connected to the inner sides of the two limiting holes 117. Four rubber bumps 119 are arranged on the outer side of the limiting strip 118. When the detection mechanism 1 operates, the rotation speed of the motor one 105 determines the speed at which the winding rod 106 winds the pull rope 107. When the pull rope 107 is pulled upward by the winding rod 106, the mounting box 108 slides upward along the sliding sleeve 109 on the outer side of the guide rod 102. The guide wheel 104 can effectively reduce the friction between the pull rope 107 and the adapter block 103, ensuring the smooth pulling of the pull rope 107 to the mounting box 108. The counterweight block 112 is connected to the combined plates one 111 and the combined plates two 113 at the bottom of the mounting box 108 through the connecting strip 115 and the pins 116. The limiting strip 118 passes through the limiting holes 117 inside the pins 116. The four rubber bumps 119 increase the friction between the limiting strip 118 and the limiting holes 117, further stabilizing the position of the counterweight block 112. When it is necessary to adjust the detection height or range, the limiting strip 118 can be pulled out, the pins 116 can be withdrawn, and counterweight blocks 112 with different weights can be replaced to meet the detection requirements under different working conditions. During the detection process, the two contact heads 110 are closely attached to the surface of the leg 4. As the mounting box 108 moves up and down, the contact heads 110 slide on the outer side of the leg 4. The pressure sensor inside the mounting box 108 converts the real-time detected pressure value changes into electrical signals. Through specific algorithm analysis, the verticality of the leg 4 can be accurately judged.Two stabilizing mechanisms 2 are arranged on both sides of the outside of the pile leg 4 for stabilizing the position of the pile leg 4; the stabilizing mechanism 2 includes a base 201, the top of the base 201 is fixedly connected to a support platform 202, and a hydraulic push rod 203 is installed on the outside of the support platform 202, and the output end of the hydraulic push rod 203 is fixedly connected to a movable seat 204, the top of the support platform 202 is fixedly connected to two connecting rods 206, the outside of the movable seat 204 is slidably connected to the outside of the connecting rod 206, the inside of the movable seat 204 is rotatably connected to a rotating rod 205, and the outside of the rotating rod 205 is rotatably connected to two connecting rods 206, one end of the two connecting rods 206 is fixedly connected to a splint 207, the outside of the splint 207 is fitted with the outside of the pile leg 4, the outside of the splint 207 is fixedly connected to a T-shaped block 208, the outside of the support platform 202 is fixedly connected to a guide sleeve 210, and the outside of the T-shaped block 208 is slidably connected to the inside of the guide sleeve 210. During operation of the stabilization mechanism 2, the extension and retraction length of the hydraulic push rod 203 can be precisely controlled based on the actual size and inclination of the pile leg 4. When the hydraulic push rod 203 extends, its output end pushes the movable seat 204 upward along the connecting rod 206, causing the rotating rod 205 to rotate, driving the two connecting rods 206 to open to the sides, thereby raising the clamping plate 207. Conversely, the hydraulic push rod 203 retracts, causing the clamping plate 207 to descend. The T-shaped block 208 on the outside of the clamping plate 207 fits tightly with the guide sleeve 210, providing precise guidance during the movement of the clamping plate 207, preventing it from shifting and ensuring that the clamping plate 207 always presses vertically and stably against the sides of the pile leg 4, fundamentally guaranteeing the stability of the pile leg 4 during testing and adjustment. The straightening mechanism 3 is arranged on the outside of the pile leg 4 on a side away from the detection mechanism 1, and is used to straighten the pile leg 4; the straightening mechanism 3 includes a base three 301, the top of the base three 301 is fixedly connected to a gantry 302, the inner side of the gantry 302 is installed with a hydraulic cylinder 303, the output end of the hydraulic cylinder 303 is fixedly connected to a movable plate 304, the inner side of the movable plate 304 is slidingly connected to the outer side of the gantry 302, the outer side of the movable plate 304 is fixedly connected to a mounting frame 305, the outer side of the mounting frame 305 is installed with a motor 2 306, the output end of the motor 2 306 is fixedly connected to a bidirectional screw rod 307, the outer side of the bidirectional screw rod 307 is threadedly connected to two threaded sleeves 308, the outer side of the threaded sleeve 308 is slidingly connected to the inner side of the mounting frame 305, the outer side of the threaded sleeve 308 is fixedly connected to a straightening block 309, and the inner side of the straightening block 309 is fitted with the outer side of the pile leg 4. In the straightening mechanism 3, the forward and reverse rotation of motor 2 306 controls the rotation direction of the bidirectional screw 307. When motor 2 306 rotates forward, the bidirectional screw 307 drives the two threaded sleeves 308 toward each other along the slide rails inside the mounting frame 305, allowing the two straightening blocks 309 to contact the edges of the pile leg 4. When motor 2 306 rotates reversely, the straightening blocks 309 move away from each other. The L-shaped design of the straightening blocks 309 provides a stable and effective contact point when contacting the pile leg 4.The thrust of the hydraulic cylinder 303 can be adjusted according to the inclination of the leg 4. When the hydraulic cylinder 303 pushes the movable plate 304 to slide inside the gantry 302, the movable plate 304 drives the mounting frame 305 and the straightening block 309 to move. The straightening block 309 applies an extrusion force to the outside of the leg 4, gradually straightening the leg 4 to a vertical state. During the entire straightening process, by monitoring the data feedback of the pressure sensor in real time, the working parameters of the second motor 306 and the hydraulic cylinder 303 can be dynamically adjusted to achieve precise adjustment of the perpendicularity of the leg 4.

[0023] Specifically, first, before detecting and adjusting the perpendicularity of the leg 4, it is necessary to start the hydraulic push rod 203 in the stabilizing mechanism 2 according to the actual dimensions, weight, and on-site construction environment of the leg 4 and other actual requirements. When the hydraulic push rod 203 extends or retracts, its output end pushes the moving seat 204 to move. During this process, the rotating rod 205 serves as a transmission hub and rotates as the moving seat 204 moves, thereby driving the two connecting rods 206 connected to it to swing accordingly. Under the precise guiding and limiting of the guide sleeve 210 on the T-shaped block 208 outside the clamping plate 207, the clamping plate 207 can move up and down smoothly and vertically. Through such an operation, the clamping plate 207 can be adjusted to a suitable position to apply a stable squeezing force from both sides of the leg 4. This squeezing can effectively offset the external force interference from the two stabilizing mechanisms 2 on the leg 4 during placement or construction, prevent the leg 4 from tilting in this direction, provide a stable basic support for subsequent perpendicularity detection and adjustment, and ensure the accuracy of the detection and adjustment results is not affected by the shaking or offset of the leg. Then, start the motor 105 in the detection mechanism 1. The motor 105 drives the winding rod 106 to rotate, and the winding rod 106 starts to wind the pulling rope 107. During the winding process of the pulling rope 107, through the contact guiding with the guide pulley 104, the pulling force is transmitted to the installation box 108, pulling the installation box 108 to move upward along the sliding sleeve 109 outside the guide rod 102. At the same time, the counterweight 112 connected to the bottom of the installation box 108 plays a key role. Under the action of gravity, it provides a downward pulling force for the installation box 108, enabling the installation box 108 to achieve stable and controllable up and down movement under the dual action of winding and gravity. The counterweight 112 is connected to the combined plate 111 and combined plate 113 at the bottom of the installation box 108 through the connecting bar 115 and the pin 116 in an inserted manner. The limiting bar 118 passes through the limiting hole 117 inside the pin 116 and cooperates with the four rubber bumps 119 on the outside, greatly enhancing the stability of the connection of the counterweight 112 and effectively avoiding the error interference caused by the shaking of the counterweight 112 during the operation of the device. As the installation box 108 moves, the two contact heads 110 on its outside always keep in close contact with the outer surface of the leg 4 and slide on the outside of the leg 4. At this time, the pressure sensor inside the installation box 108 starts to work, and continuously detects the change in the pressure value generated when the contact head 110 contacts the surface of the leg 4. When the leg 4 is in a vertical state, the pressure received by the contact head 110 during the sliding process on the outside of the leg 4 is relatively uniform; while when the leg 4 is tilted, the pressure received by the contact head 110 at different positions will show obvious differences. The pressure sensor converts these pressure value changes into electrical signals, and through specific algorithms and calculation models for analysis and processing, can accurately determine the perpendicularity of the leg 4.Compared with the traditional wire suspension or laser naked-eye observation method, this pressure sensor-based detection method can avoid human observation errors, achieve high-precision and automated detection of the perpendicularity of the leg 4, and improve the detection efficiency and accuracy.

[0024] Algorithm implementation process: Data acquisition: The pressure sensor collects the pressure value of the contact head in real time ; Preprocessing: Kalman filter denoising + normalization processing; Geometric calculation: Calculate the tilt angle according to the model ; Judgment control: Threshold judgment triggers PID closed-loop straightening.

[0025] Data acquisition and preprocessing algorithm, the pressure signal filtering algorithm uses the Kalman filtering algorithm to perform noise reduction processing on the real-time data of the pressure sensor, and establish a state space model: State equation: , where, is the state vector at time (including pressure value, change rate), is the state transition matrix, is the process noise gain matrix, is the process noise. Observation equation: , where, is the observation value of the pressure sensor, is the observation matrix, is the observation noise. Recursive formula: Prediction: ; Prediction covariance: ; Kalman gain: ; State update: ; Covariance update: , where, is the original pressure value, and are the minimum and maximum values within the sampling interval.

[0026] Perpendicularity calculation geometric model: When the two horizontal contact heads 110 can be equivalent to a single detection point, the curved surface formed by the inclination of the leg 4 can be regarded as a linear inclined plane: The inclination angle of the leg 4 is , the vertical movement distance of the contact head is ; The slope of the leg surface , the horizontal offset of the contact head ; The pressure change detected by the pressure sensor is proportional to the horizontal extrusion amount , that is is (pressure-displacement coefficient); The contact head moves from height to , collect the pressure change , vertical movement distance ; Inclination angle calculation: ; Verticality determination: Verticality deviation , when , the leg 4 is determined to be adjusted vertically.

[0027] In addition, when the detection mechanism 1 detects that the leg 4 is tilted, the straightening mechanism 3 starts to function. The second motor 306 is started, and the second motor 306 drives the bidirectional lead screw 307 to rotate. Due to the special thread design of the bidirectional lead screw 307, the two thread sleeves 308 will approach each other along the inner slide rails of the mounting frame 305 during its rotation. The thread sleeve 308 drives the straightening block 309 connected thereto to move synchronously until the two straightening blocks 309 are closely attached to the two side edges of the leg 4. The straightening block 309 is designed with an L-shaped structure, which can provide a larger contact area and a more stable force application point when contacting the leg 4, ensuring that the force applied to the leg 4 during the straightening process is uniform and effective. Then, the hydraulic cylinder 303 is started, and the hydraulic cylinder 303 pushes the movable plate 304 to slide inside the gantry 302. The movable plate 304 drives the mounting frame 305 and the straightening block 309 to move as a whole. During the movement, the two straightening blocks 309 apply a squeezing and straightening force to the outer side of the leg 4, and the leg 4 is straightened to a vertical state by gradually adjusting the inclination angle of the leg 4. During the entire straightening process, the pressure sensor of the detection mechanism 1 continuously monitors the pressure change on the surface of the leg 4 and feeds the data back to the control system in real time. This automated straightening process not only improves the adjustment efficiency but also ensures that the leg 4 finally meets the high-precision verticality requirements, meeting the safety and stable operation requirements of the offshore wind power construction platform.

[0028] Working principle: First, according to actual requirements, start the hydraulic push rod 203 to drive the moving seat 204 to move, and then the rotating rod 205 drives the connecting rod 206 to move. And under the restriction of the guide sleeve 210, the clamping plate 207 moves up and down to adjust the position, ensuring the extrusion of both sides of the pile leg 4 to avoid tilting towards the two stabilizing mechanisms 2. Then, start the first motor 105 to drive the winding rod 106 to rotate, and then the pulling rope 107 is wound, and then the installation box 108 is pulled upward. Under the action of the counterweight 112, the installation box 108 can move downward. And because the counterweight 112 is connected in an inserted manner through the pin 116, the stability of the counterweight 112 is better, avoiding error interference. In this way, the two contact heads 110 can slide on the outside of the pile leg 4, and the pressure sensor inside the installation box 108 can detect the change of the pressure value to determine the verticality of the pile leg 4, which is more accurate than observing with a plumb line or laser with the naked eye. In addition, when the pile leg 4 is tilted, start the second motor 306 to drive the bidirectional lead screw 307 to rotate, so that the two threaded sleeves 308 drive the two straightening blocks 309 to approach each other and press against the two side edges of the pile leg 4. The straightening blocks 309 are L-shaped. When the hydraulic cylinder 303 drives the movable plate 304 to move, when the two straightening blocks 309 move, they can exert an effect of squeezing and straightening the outside of the pile leg 4. In this way, the pile leg 4 can be straightened.
