Description

Technical Field

[0001] This utility model relates to the field of offshore wind power technology, and in particular to a support structure for underwater detection sensors for offshore wind power pile foundations. Background Technology

[0002] Underwater sensors for offshore wind turbine foundations are devices used to monitor the health of offshore wind turbine foundations. These sensors can acquire key data in real time on the surrounding environment and the structural condition of the foundation, such as corrosion levels, vibration, strain, and biofouling. Utilizing acoustic, optical, or electromagnetic technologies, these sensors can operate effectively in complex marine environments, ensuring the safety and stability of the wind turbine foundations. The sensors are typically mounted around the wind turbine foundation using brackets made of corrosion-resistant materials to withstand the harsh marine environment and ensure long-term stable underwater operation of the sensors.

[0003] Patent CN113916981A discloses a self-climbing deep-water pile foundation non-destructive testing device, which can be assembled according to different pile foundation cross-sectional shapes and pile diameters. It can automatically rise and fall along the pile foundation axis and simultaneously detect internal defects and surface defects of the pile foundation. It eliminates the need for manual underwater operations, greatly reducing the difficulty of underwater testing and improving the safety of underwater testing.

[0004] However, in the aforementioned patented technical solutions, aquatic plants such as aquatic grasses grow in the underwater environment. During their growth, these plants can climb and entangle the supports and sensors, affecting the sensor's detection operation. Under strong currents or waves, the dynamic movement of the aquatic plants can exert additional tension on the sensors, easily causing them to shift from their fixed positions or even break and be damaged. Therefore, the growth of aquatic plants not only affects the sensor's detection of the pile foundation but may also lead to damage to the sensors and supports.

[0005] Therefore, there is an urgent need for a support structure for underwater detection sensors on offshore wind turbine pile foundations to solve the above problems. Utility Model Content

[0044] like Figure 1 - Figure 7 As shown, this embodiment provides a support structure for an underwater detection sensor for offshore wind power pile foundations, including a pole frame 1 and a protective net 2. The pole frame 1 includes a main pile 11 and uprights 12, both extending vertically. Multiple uprights 12 are spaced around the main pile 11, and the bottom ends of both the uprights 12 and the main pile 11 are fixed to the seabed. The protective net 2 includes a horizontal net 22 and a vertical net 21. A vertical net 21 connects adjacent uprights 12. The horizontal net 22 is located at the bottom of the vertical net 21, and each vertical net 21 is connected to the horizontal net 22. The horizontal net 22 and the vertical net 21 form a sensor housing space. The sensor 100 is mounted on the pole frame 1 and located within the sensor housing space.

[0045] The underwater detection sensor support structure for offshore wind power pile foundations provided in this embodiment supports a protective net 2 through multiple uprights 12. The vertical net 21 and horizontal net 22 of the protective net 2 enclose a sensor housing space, in which the sensor 100 is placed. The protective net 2 can isolate aquatic plants, preventing them from climbing onto the sensor 100 inside the protective net 2. This allows the sensor 100 to effectively detect the main pile 11 and uprights 12, and also prevents aquatic plants from damaging the sensor 100.

[0046] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, the underwater detection sensor support structure for offshore wind turbine pile foundations also includes a lifting frame 3 and a drive unit 4. The lifting frame 3 is mounted on the pole frame 1 and located within the sensor housing space. The sensor 100 is mounted on the lifting frame 3, and the drive unit 4 is mounted on the pole frame 1, with its output end connected to the lifting frame 3. The drive unit 4 is used to drive the lifting frame 3 to move up and down vertically. Through the cooperation of the drive unit 4 and the lifting frame 3, the sensor 100 can be driven to move up and down vertically, so that the sensor 100 can detect various parts of the main pole 11 and the upright pole 12 of the pile foundation. In this embodiment, the drive unit 4 is an electric hoist; in other embodiments, other driving methods can also be used to drive the lifting frame 3 to move up and down.

[0047] Furthermore, such as Figure 1 , Figure 2and Figure 6 As shown, the underwater detection sensor support structure for offshore wind turbine pile foundations also includes a working platform 5. The working platform 5 is fixedly mounted on the main pole 11 of the pile foundation and located above the protective netting 2. The drive unit 4 is mounted on the working platform 5. The working platform 5 is provided with a rope hole 51, through which the rope 41 of the drive unit 4 passes and connects to the lifting frame 3. Specifically, the working platform 5 is located above the sea surface.

[0048] Furthermore, such as Figure 2 and Figure 4 As shown, the lifting frame 3 includes a mounting plate 31, a first sliding sleeve 32, and a second sliding sleeve 33. The first sliding sleeve 32 is fitted onto the main pole 11 of the pile foundation, and the second sliding sleeve 33 is fitted onto the upright pole 12. The mounting plate 31 connects the first sliding sleeve 32 and the second sliding sleeve 33, and the sensor 100 is mounted on the mounting plate 31. The rope 41 of the driving component 4 is connected to the first sliding sleeve 32, and the driving component 4 drives the lifting frame 3 to rise and fall through the first sliding sleeve 32. To make the rising and falling of the lifting frame 3 more stable, multiple driving components 4 can be set to jointly drive the first sliding sleeve 32.

[0049] Furthermore, such as Figure 2 and Figure 4 As shown, each upright 12 is fitted with a second sliding sleeve 33, and each second sliding sleeve 33 is connected to a first sliding sleeve 32 by an mounting plate 31. Each mounting plate 31 is equipped with a sensor 100. Multiple sensors 100 can detect the main pile 11 from various directions, and can also effectively detect each upright 12, thereby improving the detection effect of offshore wind power pile foundations.

[0050] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, the upright 12 includes an anchor rod 121 and a support rod 122. The bottom end of the anchor rod 121 is fixed to the seabed, and the top end of the anchor rod 121 is provided with a splice groove 1211. The lower part of the support rod 122 is inserted into the splice groove 1211, and the second sliding sleeve 33 is sleeved on the support rod 122.

[0051] Furthermore, such as Figure 2 , Figure 4 and Figure 5As shown, the pole frame 1 also includes a connecting rod 13, and the upright 12 includes a positioning block 123. The connecting rod 13 and the positioning block 123 are each corresponding to an anchor rod 121; that is, the connecting rod 13, the positioning block 123, and the anchor rod 121 are each corresponding to an anchor rod 121. The positioning block 123 is fitted onto the corresponding anchor rod 121 and is fixedly connected to it. The connecting rod 13 is fixedly connected to the corresponding positioning block 123 and to the main pile rod 11. The first sliding sleeve 32 is located above the connecting rod 13. The connecting rod 13 connects the anchor rod 121 and the main pile rod 11 into a single unit, allowing the anchor rod 121 and the main pile rod 11 to be more securely fixed to the seabed. The positioning block 123 facilitates the connection between the connecting rod 13 and the anchor rod 121.

[0052] Optionally, such as Figure 1 - Figure 6 As shown, the pole frame 1 also includes support plates 14, which are arranged one-to-one with the uprights 12. Each support plate 14 is located on the side of the corresponding support rod 122 away from the main pile rod 11, and its bottom end is located at the top of the positioning block 123 of the corresponding upright rod 12. Multiple hooks 141 are fixedly installed on the side of each support plate 14 facing the corresponding upright rod 12. These hooks 141 are evenly spaced, and the vertical net 21 is hooked onto the hooks 141. The support plates 14 support and fix the vertical net 21 through the hooks 141, while the positioning blocks 123 provide support for the support plates 14. Specifically, in this embodiment, the top of the positioning block 123 is provided with a groove 1231, and the bottom end of the support plate 14 is inserted into the groove 1231. The vertical net 21 is supported and fixed by the hooks 141, preventing the vertical net 21 from fitting too closely to the support rod 122 and affecting the sliding of the second sliding sleeve 33 along the support rod 122.

[0053] Furthermore, such as Figure 2 and Figure 3 As shown, the frame 1 also includes connecting components 15 corresponding to the support plates 14 one-to-one. The top end of the support plate 14 is detachably connected to the support rod 122 through the corresponding connecting components 15. In this embodiment, the cross-section of the support plate 14 parallel to the horizontal direction is arc-shaped, that is, the support plate 14 in this embodiment is an arc-shaped plate. The connecting components 15 cooperate with the grooves 1231 to fix the support plate 14.

[0054] Specifically, such as Figure 2 and Figure 3As shown, the connecting assembly 15 includes a retaining ring 151, a screw 152, and a nut 153. The retaining ring 151 is sleeved on the upper part of the support rod 122 and is fixedly connected to the support rod 122. The vertical mesh 21 is provided with a through hole. One end of the screw 152 is fixedly connected to the support rod 122, and the other end passes through the through hole on the vertical mesh 21 and is exposed to the protective mesh 2. Two nuts 153 are threadedly connected to the screw 152. The two nuts 153 are located on both sides of the vertical mesh 21 and clamp the vertical mesh 21 to fix the top of the vertical mesh 21 to the screw 152.

[0055] In summary, the underwater detection sensor support structure for offshore wind turbine piles provided in this embodiment uses a protective net 2 to shield the periphery and bottom of the sensor 100 and the lifting frame 3, thereby blocking aquatic plants growing on the seabed and preventing them from growing into the detection range of the sensor 100. This prevents the aquatic plants from affecting the detection effect of the sensor 100 on the offshore wind turbine piles and also prevents seaweed from getting tangled on the lifting frame 3 and the sensor 100, which could damage the sensor 100 and prevent it from detecting the piles. The driving component 4 applies an upward force to the first sliding sleeve 32 by winding the rope 41, which can move the lifting frame 3 and the sensor 100 mounted on it upward along the main pole 11 of the pile. Conversely, when the driving component 4 releases the rope 41, the lifting frame 3 and the sensor 100 mounted on it will move downward along the main pole 11 of the pile under their own gravity, so that the sensor 100 can detect various parts of the main pole 11 and the upright 12 of the pile.

[0056] Furthermore, when aquatic plants climb and grow on the protective net 2, the aquatic plants (such as seaweed) on the protective net 2 together with the protective net 2 form a protective wall that can resist seawater erosion. This can protect the main pile 11 and the upright 12 to a certain extent, reduce the erosion of them by seawater, and extend the service life of the main pile 11, the upright 12, and the sensor 100.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
