Description

Technical Field

[0001] This invention relates to the field of marine wind power facility monitoring equipment technology, specifically a device that can monitor the safety of marine wind power facilities in real time. Background Technology

[0002] Offshore wind power facilities refer to a series of engineering devices and systems that utilize wind energy to generate electricity in the marine environment. They mainly consist of power generation equipment, supporting structures, power transmission systems, and auxiliary facilities, and are the core equipment for developing marine renewable energy.

[0003] Since it is installed on the ocean, its support structure is particularly important. Depending on the ocean depth, there are fixed foundations and floating foundations. In shallow and medium-deep sea areas, it is mainly supported by fixed foundations. Among them, monopile foundations refer to a steel pile with a diameter of 3-8 meters that is directly inserted into the seabed. This type of support structure accounts for more than 70% of the global shallow-sea wind power.

[0004] When monopile foundations are submerged in seawater for extended periods, the attachment of marine organisms (barnacles, mussels, algae) can damage the coating integrity (acidic substances secreted by these organisms corrode the coating) and create a localized oxygen-deficient environment that accelerates corrosion. This results in a thick layer of biodegradation and corrosion on the outer side of the monopile. Over time, this biodegradation layer can reach tens of centimeters in thickness, leading to an increase in the actual diameter of the pile and a significant increase in the resistance to water flow passing through it (flow resistance). This additional resistance exacerbates the impact of waves and currents on the pile, potentially causing fatigue damage to the foundation structure in the long term and even affecting overall stability. The traditional solution is to manually remove the biodegradation by diving personnel, which is time-consuming, labor-intensive, and unable to determine the details of the underlying biodegradation and corrosion. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 - Figure 4 as well as Figure 7 and Figure 8 The device shown in the figure is for real-time monitoring of the safety of marine wind power facilities. It includes an installation platform 1, a positioning pile 2 fixed at the bottom of the installation platform 1, wind power generation equipment installed on the installation platform 1, and several monitoring seats 3. The installation platform 1 has several sliding openings 4 for sliding of the monitoring seats 3. Two monitoring ropes 5 are slidably inserted into the monitoring seats 3. The bottom of the monitoring ropes 5 is connected to an adsorption component 6. The top of the two monitoring ropes 5 is fixed to a connecting plate 7. The monitoring seat 3 is equipped with a monitoring component 8, a traction rope 9 fixed to the top of the connecting plate 7 and a traction rope 10 fixed to the monitoring seat 3. Two steering wheels 11 are rotatably installed at both ends of the monitoring seat 3. The traction rope 9 and the traction rope 10 are respectively wrapped around the outside of the two steering wheels 11. The installation platform 1 is provided with a traction component 12, which is connected to the traction rope 9 and the traction rope 10.

[0030] In this scheme, the designed adsorption component 6 is completely submerged in ocean water. Once it is adsorbed with deposits or corroded, the lifting force will change. The monitoring component 8 is used to measure the gravity of the adsorption component 6 to determine whether there are deposits or corrosion on the outside of the adsorption component 6. This allows for the determination of the condition of the deposits and corrosion on the outside of the positioning pile 2, so that personnel can promptly carry out corresponding treatment on the outside of the positioning pile 2.

[0031] It should be noted that the designed traction component 12 drives the traction rope 9 and traction rope 10 to move the monitoring seat 3 within the sliding opening 4, thereby enabling the adsorption component 6 to move along the outside of the positioning pile 2 to clean the residual attachments and rust on the outside of the positioning pile 2.

[0032] For further details, please refer to [link / reference]. Figure 4 - Figure 6 The adsorption component 6 includes an adsorption frame 13 fixed to the bottom of the two monitoring ropes 5. The adsorption frame 13 is used for adsorption of attached substances and corrosion. A locking post 15 is fixed to the top of the adsorption frame 13, and a locking frame 14 adapted to the locking post 15 is fixed to the bottom of the monitoring seat 3.

[0033] In this scheme, the designed adsorption frame 13 is a frame-shaped design with a large area, which can help adsorb marine attachments and simulate the normal corrosion state of the positioning stake 2 in the sea. After the monitoring rope 5 is pulled up, the locking post 15 is connected to the locking frame 14, which can position the adsorption frame 13 and facilitate the subsequent movement of the adsorption frame 13 along the sliding opening 4.

[0034] Among them, see Figure 4 - Figure 6 and Figure 7 as well as Figure 8 The monitoring component 8 includes a monitoring platform 16 fixed on the surface of the monitoring base 3. A pressure sensor 17 is installed on the monitoring platform 16. Two monitoring ropes 5 slide through the monitoring platform 16. A connecting plate 7 abuts against the top of the pressure sensor 17. Two sliding columns 18 are fixed on the monitoring base 3. The connecting plate 7 slides against the sliding columns 18. A steering component 19 for steering the traction rope 9 is fixed on the top of the two sliding columns 18.

[0035] It should be noted that after the locking post 15 and the locking frame 14 are separated, the monitoring rope 5 is pulled by the weight of the adsorption frame 13 itself and the weight of the attached objects and rust on its outside, so that the connecting plate 7 is against the pressure sensor 17. By monitoring the weight of the adsorption frame 13, when its weight increases to a specified weight, the amount of attached objects and rust on the outside of the positioning post 2 can be determined, which is convenient for subsequent cleaning.

[0036] For further details, please refer to [link / reference]. Figure 7 and Figure 8 The steering component 19 includes a docking wheel 20 fixed to the top of two sliding columns 18, a traction rope 9 looped around the outside of the docking wheel 20, and a docking shaft 21 rotatably mounted on the monitoring seat 3, with the traction rope 9 wrapped around the outside of the docking shaft 21.

[0037] In this scheme, the function of the steering component 19 is to turn the traction rope 9 on the connecting plate 7 so that the traction rope 9 can first pull the connecting plate 7 vertically upward, and then after the connecting plate 7 moves to the top, it will drive the entire monitoring seat 3 to move at the sliding opening 4.

[0038] Also see Figure 3 , Figure 7 and Figure 8 The traction component 12 includes a traction motor 22 fixed on the monitoring seat 3 via a motor frame. The output end of the traction motor 22 is fixed to a drive wheel 23 via a coupling. An isolation plate 24 is fixed on the drive wheel 23. Traction rope 1 9 and traction rope 2 10 are fixedly wound around the outside of the drive wheel 23 in opposite directions. Traction rope 1 9 and traction rope 2 10 are distributed on both sides of the isolation plate 24. Two traction wheels 25 are rotatably installed on the monitoring seat 3 corresponding to the two ends of the sliding opening 4. Traction rope 1 9 and traction rope 2 10 are respectively wound around the outside of the two traction wheels 25.

[0039] The traction motor 22 inside the traction component 12 drives the drive wheel 23 to rotate, causing the first traction rope 9 and the second traction rope 10 to tighten and loosen respectively, thereby providing a directional traction force to the monitoring seat 3, enabling the monitoring seat 3 to move along both ends of the sliding opening 4.

[0040] In order to enable the two traction wheels 25 to effectively distribute the traction rope 1 9 and traction rope 2 10 at the upper and lower ends of the drive wheel 23, the two traction wheels 25 are designed to have different installation heights, and the height difference between the two traction wheels 25 and the isolation plate 24 is consistent.

[0041] Meanwhile, in order to ensure that the monitoring seat 3 moves stably within the sliding opening 4, the cross-sectional shape of the monitoring seat 3 is designed to be L-shaped, and a docking arc rod 26 that slides and docks with the monitoring seat 3 is fixed inside the sliding opening 4.

[0042] It is worth noting that when the traction rope 9 is wound up, it will first pull the connecting plate 7 upward. After the connecting plate 7 moves to the top, it will then pull the monitoring seat 3 to move within the sliding opening 4. Therefore, the traction rope 10 will be loosened in advance before the monitoring seat 3 moves to improve the stability of the movement of the monitoring seat 3. Conversely, when the monitoring seat 3 moves in the opposite direction within the sliding opening 4, the connecting plate 7 will be lowered first, and after the traction rope 10 is tightened, it will drive the monitoring seat 3 to move in the opposite direction.

[0043] For further details, please refer to [link / reference]. Figure 5 and Figure 6 A connecting rod 27 is fixed inside the adsorption frame 13. A scraping frame 28 is slidably inserted on the connecting rod 27. The adsorption frame 13 is provided with a mating interface 29 for the movement of the scraping frame 28. A compression spring 30 is fitted at the bottom of the connecting rod 27 and abuts against the bottom of the scraping frame 28.

[0044] It should be noted that one side of the scraping frame 28 is attached to the positioning pile 2. When moving, it can move along the outside of the positioning pile 2 and effectively attach to the positioning pile 2. Through the designed scraping frame 28, in conjunction with the traction component 12, the monitoring seat 3 is moved within the sliding opening 4, thereby effectively removing the attachments and rust on the outside of the positioning pile 2 without the need for personnel to dive down for cleaning.

[0045] The principle behind this scheme for monitoring the attachments and corrosion on the bottom of offshore wind power facilities is as follows:

[0046] First, by using the pressure sensor 17 to abut against the connecting plate 7, the gravity of the adsorption frame 13 itself in the ocean water and the gravity of the adsorbed substances and rust on the adsorption frame 13 are monitored. By the change in gravity, the amount of adsorbed substances and rust on its outer side can be determined, thereby predicting the information of adsorbed substances and rust on the outer side of the positioning pile 2, which facilitates the subsequent cleaning operation of the adsorbed substances and rust.

[0047] Afterwards, after monitoring that a certain amount of attachments and rust are attached to the positioning pile 2, the traction motor 22 in the traction component 12 provides power to drive the drive wheel 23 to rotate, so that the traction rope 9 is first pulled by the force to pull the connecting plate 7, so that the connecting plate 7 moves up along the sliding column 18. After moving up to the top of the sliding column 18, it is limited. At this time, the monitoring rope 5 pulls the adsorption frame 13 to move up, and the locking column 15 docks with the locking frame 14, so that the adsorption frame 13 is positioned. The traction rope 9 is wound by the drive wheel 23 through the steering component 19 and the steering wheel 11, while the traction rope 10 is in a relaxed state. The traction rope 9 continues to be wound, so that the monitoring seat 3 is moved along the sliding opening 4, and the adsorption frame 13 moves synchronously. The removal frame 28 is used to remove the adsorption attachments and rust on the outside of the positioning pile 2.

[0048] After moving to one end of the slide 4, the traction motor 22 reverses, causing the traction rope 9 to loosen and the traction rope 10 to wind up, pulling the monitoring seat 3 in the opposite direction to move and reset along the slide 4.

[0049] Example 2: Please refer to Figure 4 and Figure 5 This embodiment further explains the first embodiment, the difference being that a docking ring 31 is added to the positioning pile 2, so that after the adsorption frame 13 is pulled up, the docking plate 33 contacts the protrusion 32.

[0050] Specifically, a docking ring 31 is fixed on the outside of the positioning pile 2, and several protrusions 32 are provided at the bottom of the docking ring 31. A docking plate 33 that matches the protrusions 32 is fixed on the top of the shovel frame 28.

[0051] When the scraping frame 28 moves along the positioning stake 2, it can contact several protrusions 32 through the docking plate 33, and under the action of the compression spring 30, the scraping frame 28 is driven to rise and fall during the movement, which achieves a better scraping effect on the attachment and corrosion.
