TECHNICAL FIELD
[0001] The present application relates to the offshore wind power technology field, and in particular to a deep-sea anchoring device for offshore wind farms. BACKGROUND
[0002] An offshore wind farm is a power plant composed of wind turbine generators located in the sea. Compared with land-based wind farms, offshore wind farms have higher wind energy resource utilization, mainly because the wind speed on the sea surface is higher and the wind direction is more stable. In addition, offshore wind farms can also avoid the loss of land-based power transmission lines to reduce energy transmission costs, so they are considered one of the important directions for the future development of renewable energy. Offshore wind farms mainly use two types of foundation support technology. In shallow water areas, bottom-fixed support is often used, and in deep-sea areas, floating support is often used. The deep-sea anchoring device is a key equipment for fixing the floating platform of the offshore wind farm. Common types include gravity anchors, suction anchors, and dynamic penetration anchors.
[0003] The existing deep-sea anchoring device of the dynamic penetration anchor type only needs to be released at an appropriate height during use. It will quickly sink and insert into the mud at the bottom of the sea under the action of its own gravity, thereby completing the sinking and fixing of the dynamic penetration anchor. In order to improve the fixing effect of the anchoring device, workers usually set fixed barbs or hooks on the surface of the anchoring device. However, the fixed barbs or hooks will damage the structure of the surrounding soil when the anchoring device sinks and inserts into the soil, so that the anchoring device does not contact the soil tightly enough, thereby resulting in poor fixing effect of the deep-sea anchoring device.
[0004] Based on the above situation, the present application provides a deep-sea anchoring device for offshore wind farms with good fixing effect. SUMMARY
[0005] In order to overcome the shortcomings of the existing deep-sea anchoring device of the dynamic penetration anchor type, which usually sets fixed barbs or hooks on the surface to improve the fixing effect of the anchoring device, but the fixed barbs or hooks will damage the structure of the surrounding soil when the anchoring device sinks and inserts into the soil, so that the anchoring device does not contact the soil tightly enough, thereby resulting in poor fixing effect of the deep-sea anchoring device, the present application provides a deep-sea anchoring device for offshore wind farms with good fixing effect.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.
[0031] Embodiment 1 A deep-sea anchoring device for offshore wind farms, as shown in Figures 1-5As shown, the device includes a column 1, a stop block 11, a connecting rod 12, a moving block 13, a push block 14, a locking block 15, a pressing block 16, a limiting magnetic block 17, an expansion ring 18, an air guide tube 19, and a strong magnetic block 110. The moving block 13 is slidably connected to the upper side of the inside of the column 1 via a damping ring. The connecting rod 12 is fixedly connected to the middle of the moving block 13, and the connecting rod 12 is slidably connected to the column 1. The stop block 11 is fixedly connected to the bottom of the connecting rod 12. Push blocks 14, evenly distributed around the circumference, are fixedly connected to the bottom of the moving block 13, and the push blocks 14 are slidably connected to the column 1. Locking blocks 15, evenly distributed around the circumference, are slidably connected to both the upper and lower sides of the inside of the column 1. The push blocks 14 and adjacent locking blocks 15 are pressed together. An extrusion block 16 is slidably connected to the upper side of the interior. A circumferentially distributed limiting magnetic block 17 is fixedly connected to the top of the extrusion block 16. A circumferentially distributed limiting magnetic block 17 is also fixedly connected to the bottom of the moving block 13 via a pull rope. The limiting magnetic blocks 17 on the extrusion block 16 and the limiting magnetic blocks 17 on the moving block 13 are magnetically attracted to each other. A strong magnetic block 110 is fixedly connected to the bottom of the extrusion block 16. A strong magnetic block 110 is also fixedly connected inside the column 1. The strong magnetic blocks 110 on the extrusion block 16 and the strong magnetic blocks 110 on the column 1 are magnetically attracted to each other. An expansion ring 18 is fixedly connected to the bottom of the column 1. A circumferentially distributed air guide tube 19 is fixedly connected to the inside of the column 1. The air guide tube 19 is fixedly connected to and connected to the expansion ring 18.
[0032] like Figure 4 and Figure 5 As shown, the abutment block 11 is conical.
[0033] like Figure 4 and Figure 5 As shown, the moving block 13 has circumferentially distributed seepage holes in the middle, and the column 1 has circumferentially distributed seepage grooves on the upper part.
[0034] like Figure 4 and Figure 5 As shown, the upper and lower sides of the push block 14 and the inner and outer sides of the latch block 15 are provided with inclined surfaces.
[0035] When workers need to fix the floating platform of the offshore wind farm through the deep-sea anchoring device, the external cable can be connected with the column 1 first, and then the column 1 and other components can be lifted to an appropriate height by the external hoisting equipment and released, at this time, the column 1 and other components will move downward and fall into the seawater under the action of their own gravity, and after falling into the seawater, the column 1 and other components will continue to sink under the action of their own gravity until they penetrate into the soil at the seabed, during which, when the abutment 11 moves downward to contact the hard soil at the seabed, the abutment 11 will drive the connecting rod 12, the moving block 13 and the push block 14 to slide upward relative to the column 1 under the action of the hard soil, until the abutment 11 contacts the column 1 and continues to penetrate downward under the action of the column 1, wherein the upward sliding of the push block 14 relative to the column 1 will contact and press the adjacent clamping block 15, so that the clamping block 15 extends outward and forms a barb, and the barb formed by the clamping block 15 can improve the anti-pulling performance of the column 1 and other components and reduce the risk of being pulled out when subjected to external force after extending outward and inserting into the soil, the upward sliding of the moving block 13 relative to the column 1 will drive the bottom limiting magnetic block 17 to move upward relative to the column 1 through the pull rope, and since the extrusion block 16 is limited by the internal structure of the column 1 and cannot move upward, the extrusion block 16 and the limiting magnetic block 17 at the top thereof will move relative to and separate from the limiting magnetic block 17 at the bottom of the moving block 13, at this time, the strong magnetic block 110 at the bottom of the extrusion block 16 will move downward relative to the column 1 under the action of its own gravity and the magnetic force of the strong magnetic block 110 inside the column 1, and inject the gas in the cavity composed of the column 1 and the extrusion block 16 into the expansion ring 18 through the air guide pipe 19, until the strong magnetic block 110 on the extrusion block 16 and the strong magnetic block 110 on the column 1 are adsorbed and fixed together, the expansion ring 18 expands and becomes larger immediately and tightly adheres to the surrounding soil, so as to increase the contact area and friction between the device and the soil and improve the stability of the device, and the upward sliding of the moving block 13 relative to the column 1 will also make the seepage hole on the moving block 13 communicate with the seepage groove on the column 1, at this time, the external seawater will enter the cavity composed of the column 1, the moving block 13 and the extrusion block 16 through the seepage groove and the seepage hole, so as to fill the cavity inside the column 1 with seawater, thereby increasing the counterweight of the column 1 and other components and improving the overall stability of the device.
[0036] Example 2 On the basis of example 1, as Figure 6 and Figure 7As shown, the device also comprises a barb mechanism arranged on the column 1, which comprises rotating clamping frames 2, guide frames 21, limiting frames 22 and arc-shaped compression springs 23. Two groups of rotating clamping frames 2 are equidistantly distributed on the circumference and are rotatably connected to the upper and lower sides of the outer part of the column 1. The inner sides of the rotating clamping frames 2 are fixedly connected with the guide frames 21, which are slidingly connected with the column 1. The arc-shaped compression springs 23 are fixedly connected between the guide frames 21 and the column 1. The upper part of the push block 14 is fixedly connected with the limiting frame 22, which is slidingly connected with the column 1 and in contact with the adjacent guide frame 21.
[0037] When the push block 14 moves upward relative to the column 1 under the action of the abutting block 11 and other components, the limiting frame 22 will also move upward relative to the column 1 together with the push block 14 and no longer block the guide frame 21. At this time, the guide frame 21 will slide upward under the action of the arc-shaped compression spring 23 that has been compressed and drive the rotating clamping frame 2 to rotate outward. In this way, the rotating clamping frame 2 can rotate outward and form a barb after the column 1 and other components are inserted into the soil under the sea, thereby effectively increasing the contact area and friction between the column 1 and the soil under the sea and generating strong resistance when the column 1 is subjected to an upward pulling force to avoid the column 1 being pulled out.
[0038] As shown in Figure 2 and Figure 8 , the device also comprises a balancing mechanism arranged on the column 1, which comprises a water rotating block 3 and guide channels 31. The water rotating block 3 is rotatably connected to the lower part of the column 1, and the guide channels 31 are equidistantly distributed on the circumference of the middle part of the water rotating block 3.
[0039] When the column 1 and the water rotating block 3 and other components are constantly sinking in the water under the action of their own gravity, the conical water rotating block 3 will be in contact with the water flow at the bottom of the column 1 and rotate under the action of the water flow. In this way, the water flow can be broken by the conical water rotating block 3, and the water flow can be dispersed by the guide channels 31 on the water rotating block 3, thereby effectively reducing the resistance received by the column 1 and other components when falling in the water and enabling them to be quickly and deeply inserted into the soil. In addition, the rotating water rotating block 3 can also generate a certain rotational torque and water flow reaction force, thereby improving the stability of the column 1 and other components when falling in the water to avoid deviation or tilting.
[0040] As shown in Figure 2 and Figure 9 , the device also comprises a filtering mechanism arranged on the column 1, which comprises a net frame 4 and isolation nets 41. The net frame 4 is fixedly connected to the top of the column 1, and the isolation nets 41 are equidistantly distributed on the circumference of the middle part of the net frame 4.
[0041] When the external seawater enters the cavity inside the column 1 through the seepage groove and the seepage hole, the seawater will be filtered by the isolation net 41 on the net frame 4 first, so as to intercept and isolate the sand and sundries in the seawater, thereby avoiding the sand and sundries from entering the column 1 and causing the seepage hole and the seepage groove to be blocked.
[0042] As shown in Figure 2 and Figure 10 Further comprising a hindering mechanism, which is arranged on the column 1 and comprises the clamping beads 5 and the springs 51. The circumferentially equidistantly distributed clamping beads 5 are all slidingly connected to the upper portion of the column 1, and the springs 51 are fixed between the clamping beads 5 and the column 1. The clamping beads 5 are in extrusion fit with the moving block 13.
[0043] When the moving block 13 moves upward relative to the column 1 under the action of the abutting block 11 and other components, the moving block 13 will contact and extrude the surrounding clamping beads 5, so as to make the clamping beads 5 slide away from the moving block 13, and the springs 51 are compressed immediately. In this way, the movement of the moving block 13 and other components can be hindered by the clamping beads 5 and the springs 51, so as to avoid the moving block 13 and other components from moving upward relative to the column 1 and triggering the clamping block 15 and the rotating clamping frame 2 and other components due to accidents, and also avoid the abutting block 11 from triggering the clamping block 15 and the rotating clamping frame 2 and other components through the moving block 13 when it contacts with the soft soil of the seabed.
[0044] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
