Abstract
Description
Technical Field
[0001] This utility model relates to the field of suction anchor technology, specifically a floating offshore wind power suction anchor. Background Technology
[0002] Offshore wind power suction anchors are innovative anchoring foundations designed specifically for deep-sea wind power projects. They achieve efficient installation and reliable load-bearing through the principle of negative pressure sinking.
[0003] The seabed topography is generally uneven (such as local undulations, slopes, or reefs), which often results in uneven contact between the skirt of a traditional suction anchor and the seabed after initial positioning, making it difficult to form an effective initial seal, and the anchor body is prone to significant tilting. To ensure the smooth progress of subsequent suction penetration and that the final installation verticality meets design requirements, it is usually necessary to rely on repeated adjustments of the installation vessel's lifting cables and precise intervention from the ROV (Remotely Operated Vehicle) for multiple leveling operations. This process significantly increases the installation cycle and complexity. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows:
[0006] A floating offshore wind turbine suction anchor includes an adsorption mechanism, a horizontal mechanism, and a leveling mechanism. The adsorption mechanism includes an anchor body and a support frame connected to the bottom of the anchor body. The horizontal mechanism includes a universal joint connected to the support frame, a connecting rod connected to the movable end of the universal joint, and a flexible enclosure sleeved on the outside of the universal joint and connected to the support frame. The leveling mechanism includes multiple shells penetrating the anchor body, a foot slidingly penetrating the bottom of the shell, a tension spring connecting the anchor body and the foot, multiple liquid bladders vertically penetrating the top of the anchor body, a connecting pipe connecting the shells and the liquid bladders, a one-way valve installed on the connecting pipe, and a pressure plate fitted to the inside of the liquid bladder and connected to the connecting rod.
[0007] By adopting the above technical solution, the anchor body is sunk to the bottom. The seabed topography causes the anchor body to tilt to different degrees. Correspondingly, the connecting rod on the universal joint will tilt in the tilting direction. Then, the pressure plate in the tilting direction squeezes the liquid bladder on its outer side. The liquid in the liquid bladder is then injected into the cavity through the connecting pipe. The one-way valve on the connecting pipe prevents the liquid from flowing back. Then, the liquid squeezes the support leg to descend, thereby changing the anchor body's placement state. The self-adjusting function reduces the installation cycle and installation complexity.
[0008] In a preferred embodiment, the present invention can be further configured such that the bottom of the support frame and the bottom of the anchor body are located on the same horizontal plane, and the support frame is configured as a round table.
[0009] In a preferred embodiment, the present invention can be further configured such that: multiple shells are arranged in a matrix, and the liquid bladder is connected to the interior of the shells via connecting pipes.
[0010] In a preferred embodiment, the present invention can be further configured such that: the top of the support leg is T-shaped, the housing has a cavity inside suitable for raising and lowering the support leg, and the tension spring is located at the top of the cavity.
[0011] In a preferred embodiment, the present invention can be further configured such that: the bottom end of the support leg is surrounded by multiple extension plates, which are equally spaced and arranged in a ring.
[0012] In a preferred embodiment, the present invention can be further configured such that: a skirt is sleeved on the outside of the anchor body, and the bottom of the skirt is located on the same horizontal plane as the bottom of the anchor body.
[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0014] In this invention, the anchor body is sunk to the bottom, and the seabed topography causes the anchor body to tilt to different degrees. Correspondingly, the connecting rod on the universal joint will tilt in the tilting direction. Then, the pressure plate in the tilting direction squeezes the liquid bladder on its outer side, and the liquid in the liquid bladder is injected into the cavity through the connecting pipe. The one-way valve on the connecting pipe prevents the liquid from flowing back, and then the liquid squeezes the support leg to descend, thereby changing the anchor body's placement state. The self-adjusting function reduces the installation cycle and installation complexity. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a floating offshore wind power suction anchor.
[0031] Example 1:
[0032] Combination Figure 1-7 As shown, the present invention provides a floating offshore wind power suction anchor, including an adsorption mechanism 100, a horizontal mechanism 200 and a leveling mechanism 300. The adsorption mechanism 100 includes an anchor body 110 and a support frame 120 connected to the bottom of the anchor body 110.
[0033] A horizontal mechanism 200 includes a universal joint 210 connected to the support frame 120, a connecting rod 220 connected to the movable end of the universal joint 210, and a flexible enclosure 230 sleeved on the outside of the universal joint 210 and connected to the support frame 120.
[0034] The leveling mechanism 300 includes multiple housings 310 penetrating the anchor body 110, a support leg 320 slidingly penetrating the bottom of the housing 310, a tension spring 330 connecting the anchor body 110 and the support leg 320, multiple liquid bladders 340 vertically penetrating the top of the anchor body 110, a connecting pipe 350 connecting the housings 310 and the liquid bladders 340, a one-way valve 360 installed on the connecting pipe 350, and a pressure plate 370 fitted to the inside of the liquid bladders 340 and connected to the connecting rod 220.
[0035] Furthermore, the bottom of the support frame 120 and the bottom of the anchor body 110 are located on the same horizontal plane. The support frame 120 is set as a round table. The layout design of the support frame 120 can increase the contact area between the anchor body 110 and the seabed and improve the adsorption capacity of the anchor body 110.
[0036] Furthermore, multiple shells 310 are arranged in a matrix, and the liquid bladder 340 is connected to the interior of the shell 310 through a connecting pipe 350. This layout design provides conditions for adjusting the anchor body 110 in multiple directions.
[0037] Furthermore, the top of the support leg 320 is T-shaped, and the housing 310 has a cavity inside that is suitable for the lifting and lowering of the support leg 320. The tension spring 330 is located at the top of the cavity. The cavity provides conditions for receiving the liquid in the liquid bag 340.
[0038] Example 2:
[0039] Combination Figure 2 , 5 and Figure 6 As shown, based on Embodiment 1, the bottom end of the support leg 320 is surrounded by multiple extension plates 400. The multiple extension plates 400 are evenly spaced and arranged in a ring. The extension plates 400 can increase the contact area between the support leg 320 and the seabed, thereby improving the contact area between the support leg 320 and the seabed.
[0040] Example 3:
[0041] Combination Figure 1 and Figure 2 As shown in the above embodiment, the anchor body 110 is fitted with a skirt 500 on the outside. The bottom of the skirt 500 is located on the same horizontal plane as the bottom of the anchor body 110. The skirt 500 can improve the adsorption capacity of the anchor body 110 to the seabed.
[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the anchor body 110 is sunk to the bottom. Then, the topography of the seabed causes the anchor body 110 to tilt to different degrees. Correspondingly, the connecting rod 220 on the universal joint 210 will tilt in the tilting direction. Then, the pressure plate 370 in the tilting direction squeezes the liquid bladder 340 on its outer side. Then, the liquid in the liquid bladder 340 is injected into the cavity through the connecting pipe 350. The one-way valve 360 on the connecting pipe 350 prevents the liquid from flowing back. Then, the liquid squeezes the support leg 320 down, thereby changing the placement state of the anchor body 110. This process continues until the anchor body 110 is placed horizontally and the skirt 500 is tightly attached to the seabed.
[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
