Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power pile foundation monitoring, and in particular to a real-time monitoring device for scouring of offshore wind power pile foundations. Background Art

[0002] As a key force driving the green transformation of the global energy structure, offshore wind power has become a key focus of my country's wind power development due to its significant advantages, including cleanliness, efficiency, stability, lack of land resources, lack of terrain restrictions, high offshore wind speeds, and large single-unit capacity. In existing offshore wind farms, pile foundations are widely used due to their simple structure, convenient construction, and good load-bearing performance. Therefore, the development of a device that can accurately monitor the scouring of offshore wind turbine pile foundations in real time is urgent. However, the existing real-time monitoring device for scour of offshore wind power pile foundations still has some problems when used: First, there is a lack of protective structure for the monitoring camera itself. The monitoring components are in water for a long time and are continuously impacted by water flow, which can easily cause damage to the camera, making it impossible to achieve real-time monitoring of pile foundation erosion.

[0003] Secondly, the existing monitoring device lacks a lifting and adjusting structure for the monitoring component, and cannot flexibly adjust the height position of the monitoring component in the water according to actual needs, which limits the monitoring range of the device to a certain extent.

[0004] In addition, the installation stability of the existing monitoring structure is insufficient. Due to the long-term impact of water flow, the monitoring structure is prone to loosening or even falling off, seriously affecting the normal progress of real-time monitoring work. Summary of the Invention

[0005] In order to solve the problems in existing monitoring devices of lacking a protective structure for the monitoring camera body, lacking a lifting and adjusting structure for the monitoring components, and insufficient installation stability of the monitoring structure; the purpose of the present invention is to provide a real-time monitoring device for scour of offshore wind power pile foundations.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: a real-time monitoring device for scour of offshore wind power pile foundation, comprising a pile basic body, a connecting ring is slidably sleeved on the outer surface of the pile basic body, and a lifting assembly used in conjunction with the connecting ring is provided on the outer surface of the pile basic body. The overall structural design realizes the position adjustment of the monitoring component through the sliding cooperation between the connecting ring and the pile basic body in combination with the lifting assembly. The annular array on the upper surface of the connecting ring is movably connected with a connecting rod, and the connecting rod layout of the annular array can fully cover the monitoring area around the pile. The upper surface of the connecting ring is provided with a fixing assembly used in conjunction with the connecting rod, and the fixing assembly enhances the installation stability. The bottom end of the connecting rod is fixedly connected to a mounting plate, and a monitoring camera body is fixedly installed on the lower surface of the mounting plate. The outer surface of the mounting plate is provided with a protective assembly used in conjunction with the monitoring camera body. The protective assembly ensures the safety of the core monitoring components. The components work together to form a complete real-time monitoring system, which provides reliable structural support for the scour monitoring of offshore wind power pile foundation.

[0007] Preferably, the protective assembly includes a protective cover, which is movably connected to the lower surface of the mounting plate, and the monitoring camera body is arranged inside the protective cover, and the protective cover is a transparent cover. In the protective assembly, the transparent protective cover can prevent seawater from directly impacting the monitoring camera body without affecting the shooting field of view. The upper surface of the protective cover is provided with a first groove, and the inner wall of the first groove is fixedly connected with a first sealing ring. The lower surface of the mounting plate is provided with a second groove, and the inner wall of the second groove is fixedly installed with a second sealing ring. The shapes of the first sealing ring and the second sealing ring match, and the positions of the first sealing ring and the second sealing ring are correspondingly arranged. The corresponding cooperation of the first sealing ring and the second sealing ring forms a double seal. The rubber sealing plate card plate further improves the sealing performance and effectively prevents seawater from infiltrating. Card plates are symmetrically fixedly connected on both sides of the protective cover, and the card plates are rubber sealing plates. A first anti-rust bolt is threadedly connected between the card plate and the mounting plate. The first anti-rust bolt ensures that the protective cover is firmly connected in a high-salt environment, greatly reducing the risk of camera damage and ensuring the continuity of real-time monitoring.

[0008] Preferably, the lifting assembly includes a vertical shell, the vertical shell is fixedly mounted on the outer surface of the pile basic body, a micro servo motor is fixedly mounted on the upper surface of the vertical shell, a protective shell for use with the micro servo motor is provided on the upper surface of the vertical shell, the micro servo motor is fixedly mounted inside the protective shell, the protective shell protects the micro servo motor from seawater erosion and prolongs its service life, the output end of the micro servo motor passes through the upper surface of the vertical shell and is fixedly connected to a screw, the bottom end of the screw is connected to the inner wall of the vertical shell in a damping rotation manner, the lifting assembly drives the screw to rotate by the micro servo motor, and the outer surface of the screw is screwed The grooved sleeve is provided with a slider, and moving rods are symmetrically fixedly connected on both sides of the slider. Guide grooves for cooperating with the moving rods are symmetrically opened on both sides of the vertical shell. The moving rod passes through the guide groove, and the slider is slidably connected to the inner cavity of the vertical shell. The moving rod is slidably connected to the inner wall of the guide groove. The bottom end of the moving rod is fixedly connected to the upper surface of the connecting ring, driving the slider and the moving rod to move smoothly along the guide groove, realizing the height adjustment of the connecting ring and the monitoring component, and expanding the monitoring range. The sliding cooperation between the slider and the vertical shell, the moving rod and the guide groove ensures the stability and accuracy of the adjustment process, and meets the scouring monitoring needs of different depths.

[0009] Preferably, the fixing assembly includes a fixing ring, which is slidably sleeved on the outer surface of the pile basic body, and the lower surface of the fixing ring is movably clamped with the upper surface of the connecting rod. The annular array on the lower surface of the fixing ring is fixedly connected with an anti-slip pad, and the anti-slip pad is movably clamped on the upper surface of the connecting rod. A second anti-rust bolt is symmetrically threaded between the fixing ring and the connecting ring. In the fixing assembly, the fixing ring and the connecting ring are connected by a second anti-rust bolt to clamp the connecting rod. The anti-rust bolt ensures the connection strength in the marine environment, and the anti-slip pad increases the friction with the connecting rod to prevent the connecting rod from sliding.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Figure 1-8 As shown, the present invention provides a real-time monitoring device for scour of offshore wind power pile foundations, including a pile basic body 1, the outer surface of the pile basic body 1 is slidably sleeved with a connecting ring 5, the outer surface of the pile basic body 1 is provided with a lifting component 3 used in conjunction with the connecting ring 5, and the lifting component 3 is matched with the sliding sleeve of the connecting ring 5 and the pile basic body 1, providing a basic installation structure for height adjustment of the monitoring component, so that the lifting operation can be carried out stably, and the connecting ring 5 is made of high-strength corrosion-resistant alloy material, which can not only reduce the wear caused by long-term sliding, but also resist seawater corrosion, the upper surface of the connecting ring 5 is movably clamped with a connecting rod 6 in an annular array, and the movable clamping method of the annular array allows the connecting rod 6 to flexibly adapt to different monitoring angle requirements, and is easy to install and disassemble, the upper surface of the connecting ring 5 is provided with a fixing component 4 used in conjunction with the connecting rod 6, and the fixing component 4 can be movable clamped The connecting rod 6 is fixed to prevent it from loosening under the impact of water flow. The bottom end of the connecting rod 6 is fixedly connected to a mounting plate 7. The fixed connection between the connecting rod 6 and the mounting plate 7 provides a stable mounting carrier for the monitoring camera body 8. The lower surface of the mounting plate 7 is fixedly mounted with a monitoring camera body 8. The monitoring camera body 8 is the core component for realizing real-time monitoring of pile foundation scouring, and can directly obtain image information of the scouring situation. The monitoring camera body 8 is transmitted wirelessly here. The monitoring camera body 8 adopts an industrial-grade underwater high-definition camera with night vision function and wide dynamic range. It can clearly capture the scouring form around the pile in turbid seawater environment, which is a conventional technical means. The outer surface of the mounting plate 7 is provided with a protective component 2 used in conjunction with the monitoring camera body 8. The protective component 2 provides protection for the monitoring camera body 8 to ensure its normal operation in the marine environment.

[0023] The protective assembly 2 includes a protective cover 23, which is movably connected to the lower surface of the mounting plate 7. The monitoring camera body 8 is arranged inside the protective cover 23. The protective cover 23 wraps the monitoring camera body 8 inside, which can block direct impact of water flow and collision with marine debris. The movable connection method facilitates the disassembly and replacement of the protective cover 23. The protective cover 23 is a transparent cover. The protective cover 23 is injection-molded with a polycarbonate transparent material, which has both impact resistance and light transmittance. The protective cover 23 made of transparent material ensures that the shooting field of view of the monitoring camera body 8 is not blocked, ensuring the clarity of the monitoring image. A first groove 24 is provided on the upper surface of the protective cover 23, and a first sealing ring 21 is fixedly connected to the inner wall of the first groove 24. A second groove 27 is provided on the lower surface of the mounting plate 7.

The corresponding cooperation between the first sealing ring 21 and the second sealing ring 25 enhances the sealing performance of the connection between the protective cover 23 and the mounting plate 7, and prevents seawater from penetrating into the protective cover 23 and damaging the monitoring camera body 8. The two sides of the protective cover 23 are symmetrically fixedly connected with a card plate 22, and the card plate 22 is a rubber sealing plate. A first anti-rust bolt 26 is threadedly connected between the card plate 22 and the mounting plate 7. The rubber card plate 22 further improves the sealing performance. The first anti-rust bolt 26 can maintain the connection strength for a long time in the high-salt environment of the ocean, ensuring that the protective cover 23 is firmly connected to the mounting plate 7.

[0024] The lifting assembly 3 includes a vertical shell 34, which is fixedly mounted on the outer surface of the pile basic body 1. The vertical shell 34 provides a stable installation foundation and a protective shell for other components of the lifting assembly 3 to prevent internal components from being damaged by water impact. A micro servo motor 31 is fixedly mounted on the upper surface of the vertical shell 34. A protective shell 36 is provided on the upper surface of the vertical shell 34 for use with the micro servo motor 31. The micro servo motor 31 is fixedly mounted inside the protective shell 36. The protective shell 36 protects the micro servo motor 31, reduces the erosion of the motor by seawater and salt spray, and extends its service life. The output end of the micro servo motor 31 passes through the upper surface of the vertical shell 34 and is fixedly connected to a screw 35. The bottom end of the screw 35 is connected to the inner wall of the vertical shell 34 for damping rotation. The micro servo motor 31 provides a power belt The movable screw 35 rotates, and the damped rotation connection ensures the stability of the rotation of the screw 35. The outer surface of the screw 35 is threadedly sleeved with a slider 32, and the two sides of the slider 32 are symmetrically fixedly connected with the moving rod 33. The two sides of the vertical shell 34 are symmetrically provided with guide grooves 37 for cooperating with the moving rod 33. The moving rod 33 passes through the guide grooves 37. The slider 32 is slidably connected to the inner cavity of the vertical shell 34, and the moving rod 33 is slidably connected to the inner wall of the guide groove 37. The rotation of the screw 35 drives the slider 32 to move up and down, and the guide groove 37 guides the moving rod 33 to ensure that the slider 32 and the moving rod 33 move smoothly. The bottom end of the moving rod 33 is fixedly connected to the upper surface of the connecting ring 5. The movement of the moving rod 33 drives the connecting ring 5 to move up and down, thereby realizing the adjustment of the height of the monitoring component to meet the monitoring requirements of different depths.

[0025] The fixing assembly 4 includes a fixing ring 41, which is slidably sleeved on the outer surface of the pile basic body 1, and the lower surface of the fixing ring 41 is movably engaged with the upper surface of the connecting rod 6. The movable engagement of the fixing ring 41 and the connecting rod 6 provides an upward fixing point for the connecting rod 6, thereby enhancing the stability of the installation of the connecting rod 6. The annular array on the lower surface of the fixing ring 41 is fixedly connected with an anti-slip pad 43, and the anti-slip pad 43 is movably engaged with the upper surface of the connecting rod 6. The anti-slip pad 43 can increase the friction with the connecting rod 6 to prevent relative sliding between the fixing ring 41 and the connecting rod 6. A second anti-rust bolt 42 is symmetrically threaded between the fixing ring 41 and the connecting ring 5. The second anti-rust bolt 42 firmly connects the fixing ring 41 to the connecting ring 5, is not easy to rust and fail in the marine environment, further strengthens the installation of the connecting rod 6, and avoids the loosening of the monitoring structure caused by water impact.

[0026] Working principle: First, the overall installation and fixation of the device are realized by relying on the connecting ring 5 and the fixing assembly 4. The connecting ring 5 is slidably sleeved on the outer surface of the pile basic body 1, providing a basic installation carrier for the entire monitoring structure.

[0027] The connecting rods 6 are movably connected to the upper surface of the connecting ring 5 in a circular array, and the bottom ends thereof are connected to the monitoring camera body 8 through the mounting plate 7 to form the main frame of the monitoring structure.

[0028] At this time, the fixing ring 41 in the fixing assembly 4 is slidably sleeved on the pile basic body 1, and the anti-slip pad 43 on its lower surface is movably engaged with the upper surface of the connecting rod 6, and then the fixing ring 41 is symmetrically connected to the connecting ring 5 through the second anti-rust bolt 42. The friction force of the anti-slip pad 43 and the tightening force of the bolt are used to firmly fix the connecting rod 6 on the connecting ring 5 to avoid the loosening of the monitoring structure caused by the impact of water flow, thereby ensuring the stability of the installation of the monitoring device.

[0029] Secondly, the protective component 2 provides all-round protection for the monitoring camera body 8. The protective cover 23 is movably connected to the lower surface of the mounting plate 7, completely wrapping the monitoring camera body 8. Since the protective cover 23 is a transparent cover, it will not block the camera's shooting field of view.

[0030] At the same time, the first sealing ring 21 in the first groove 24 on the upper surface of the protective cover 23 matches the second sealing ring 25 in the second groove 27 on the lower surface of the mounting plate 7 in shape and position, and the two fit tightly together to form a double sealing structure.

[0031] The rubber sealing plate clamps 22 on both sides of the protective cover 23 are connected to the mounting plate 7 through the first anti-rust bolts 26, further enhancing the sealing, effectively preventing seawater from penetrating into the interior of the protective cover 23, and avoiding the monitoring camera body 8 from being directly impacted by the water flow or damaged by seawater erosion, thereby ensuring its normal shooting function.

[0032] Finally, the lifting assembly 3 adjusts the height of the monitoring component to expand the monitoring range. The vertical shell 34 is fixed to the outer surface of the pile basic body 1, and the screw 35 inside it is driven to rotate by the micro servo motor 31 in the protective shell 36.

[0033] When the screw 35 rotates, the threaded slider 32 slides along the inner cavity of the vertical shell 34, driving the moving rods 33 on both sides to slide synchronously along the guide groove 37, and the bottom end of the moving rod 33 is fixedly connected to the connecting ring 5, so the connecting ring 5 will move up and down with the moving rod 33, and then drive the monitoring camera body 8 and the protective component 2 to rise and fall as a whole through the connecting rod 6 and the mounting plate 7.

[0034] By controlling the forward and reverse rotation of the micro servo motor 31, the height position of the monitoring camera body 8 in the water can be flexibly adjusted so that it can capture the scouring conditions around the pile at different depths and realize all-round real-time monitoring.

[0035] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
