Description

Technical Field

[0001] This invention relates to a connection method for a quick-connect coupling for mooring anchor chains in offshore wind power projects, belonging to the technical field of offshore wind power equipment. Background Technology

[0002] Offshore wind farms typically require mooring systems to anchor wind turbines to the seabed to ensure their stability under wind conditions. The anchor chain in the mooring system is a crucial component connecting the wind turbine to the seabed, and its safety and reliability are essential for the operation of the entire wind farm.

[0003] The existing anchor chain is connected to the wind turbine equipment through anchor chain accessories such as shackles. However, shackles (see Chinese Patent Publication No. CN212407278U) are connected by threads. The threads of marine threads are prone to rust, which causes the rotating threads of the shackle to fail and prevents quick docking. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a connection method for a quick-connect coupling for offshore wind power mooring anchor chains.

[0005] The present invention is achieved through the following technical solutions.

[0006] This invention provides a connection method for a quick-connect coupling of offshore wind power mooring anchor chains, comprising:

[0007] The process of using two quick-connect couplings to quickly connect the mooring anchor chains for offshore wind power mooring.

[0008] The quick-connector connection process is as follows: the connecting block of one quick-connector for offshore wind power mooring anchor chain reconnection is fixedly connected to the mooring anchor chain on the sea surface pillar, and the connecting block of another quick-connector for offshore wind power mooring anchor chain reconnection is fixedly connected to the mooring anchor chain of the offshore wind power floating foundation. Then, the U-shaped hooks of the two quick-connectors for offshore wind power mooring anchor chain reconnection can be docked and engaged. The protrusions of the two U-shaped hooks contact each other, and the fastening mechanism locks and limits the ends of the U-shaped hooks, thus realizing the quick-connector connection process.

[0009] The quick-connector connection process includes: adjusting the angle of the U-shaped hook inside the housing, then offsetting the semi-cylinders in the two housings, and then mating them together. The two U-shaped hooks respectively contact the two protrusions on the U-shaped hooks, causing the U-shaped hooks to rotate around the rotating axis, so that the two U-shaped hooks are in an interlocking state. Then, the magnet block is pulled, causing the sleeve to extend from the connecting block, forming a squeezing force on the guide rod exposed on the outer surface of the housing, causing the spring to contract, and the guide rod to move towards the U-shaped hooks. The limiting block moves in the second limiting groove and abuts against the U-shaped hooks. The outer surface of the limiting block fits into the slot, completing the fastening. During the movement of the two magnet blocks, they come into contact together and, under the action of magnetic force, form a closed protection for the quick-connect mechanism on the two connectors, completing the quick connection.

[0010] The quick-connect coupling for offshore wind power mooring chains includes:

[0011] Connecting block for fixed connection with mooring anchor chain;

[0012] A rotating column is rotatably installed inside the connecting block. The rotating column can rotate around the axis of the connecting block, and a connecting column is fixed on the rotating column.

[0013] The connecting column is fixedly connected to a quick-connect mechanism.

[0014] The connecting block has a slidable sleeve that can slide along the axial direction of the connecting block, and a magnet block that generates magnetic attraction is fixed on the sleeve.

[0015] The quick-connect mechanism is equipped with a fastening mechanism, which locks and limits the quick-connect mechanism.

[0016] The quick-connect mechanism includes a housing fixed to the connecting post;

[0017] A U-shaped hook is rotatably mounted on the end of the housing via a rotating shaft. A protrusion is fixed on the inner surface of the U-shaped hook. The two U-shaped hooks can be mated and engaged, with the protrusions of the two U-shaped hooks contacting each other.

[0018] The fastening mechanism is installed on the housing and locks and limits the end of the U-shaped hook with protrusions.

[0019] The fastening mechanism includes two limiting blocks that correspond to the U-shaped hook's clamping groove, and the limiting blocks are symmetrically arranged vertically; the limiting blocks are installed and accommodated in the second limiting groove of the housing;

[0020] A guide rod is fixedly connected to the limiting block. The guide rod is installed in the first limiting groove of the housing. A limiting ring is screwed onto the guide rod. A spring is sleeved on the guide rod below the limiting ring. The two ends of the spring are fixed to the second limiting groove and the limiting block, respectively. In the normal state, the spring retracts the limiting block into the second limiting groove. At this time, the top of the guide rod extends out of the first limiting groove. The sleeve slides along the axis of the connecting block and presses the top of the guide rod inward. The magnet is attracted to the housing. The limiting block is in the slot of the U-shaped hook and locks and limits the U-shaped hook.

[0021] The beneficial effects of this invention are as follows: the anchor chain is first fixedly connected to the quick-connect coupling of the offshore wind power mooring anchor chain, and then the anchor chains are docked through the quick-connect coupling of the offshore wind power mooring anchor chain. During docking, the two U-shaped hooks are in an interlocking shape, causing the spring to contract, the guide rod to move towards the U-shaped hook, and the limiting block moves in the second limiting groove to abut against the U-shaped hook. This avoids the use of threaded connection and solves the problem that the threads of offshore threads are prone to rust, which leads to the failure of the shackle rotation thread and prevents quick docking.

[0031] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0032] like Figures 1 to 5 As shown.

[0033] This application discloses a quick-connect coupling for reconnecting mooring chains in offshore wind power projects, comprising:

[0034] The connecting block 1 is a cylindrical shape and is used to fix it to the mooring anchor chain. A rotating column 6 is rotatably installed inside the connecting block 1. The rotating column 6 can rotate around the axis of the connecting block 1, and a connecting column 5 is fixed on the rotating column 6.

[0035] The connecting block 1 has a slidable sleeve 7, which can slide along the axial direction of the connecting block 1. A magnet block 4 that generates magnetic attraction is fixed on the sleeve 7.

[0036] The connecting column 5 is fixedly connected to the quick-connect mechanism 2, and the quick-connect mechanism 2 is equipped with a fastening mechanism 3, which locks and limits the quick-connect mechanism 2.

[0037] In use, two quick-connect couplings for offshore wind power mooring anchor chains are used. One quick-connect coupling is fixedly connected to the mooring anchor chain on the sea surface pillar, and the other quick-connect coupling is fixedly connected to the mooring anchor chain of the offshore wind power floating foundation. Then, the quick-connect mechanism 2 of the couplings quickly connects with each other, so that the offshore wind power floating foundation is moored and fixed on the sea surface pillar.

[0038] The quick-connect mechanism 2 includes a housing 201 fixed to the connecting post 5, and the housing 201 is composed of a cylinder and a semi-cylinder;

[0039] A U-shaped hook 205 is rotatably mounted on the end of the housing 201 via a rotating shaft 204. A protrusion 206 is fixed on the inner surface of the U-shaped hook 205. The two U-shaped hooks 205 can be engaged and interlocked. The protrusions 206 of the two U-shaped hooks 205 are in contact, similar to the engagement principle of automatic hooks on trains.

[0040] The fastening mechanism 3 is installed on the housing 201, and the fastening mechanism 3 locks and limits the end of the U-shaped hook 205 with the protrusion 206; the fastening mechanism 3 includes a limiting block 302 that corresponds to the slot 207 on the U-shaped hook 205, and there are two limiting blocks 302 that are symmetrically arranged vertically; the limiting blocks 302 are installed and accommodated in the second limiting groove 203 of the housing 201;

[0041] The guide rod 301 is fixedly connected to the limiting block 302. The guide rod 301 is installed in the first limiting groove 202 of the housing 201. The limiting ring 304 is screwed onto the guide rod 301. A spring 303 is sleeved on the guide rod 301 below the limiting ring 304. The two ends of the spring 303 are fixed to the second limiting groove 203 and the limiting block 302 respectively. In the normal state, the spring 303 retracts the limiting block 302 into the second limiting groove 203. At this time, the top of the guide rod 301 extends out of the first limiting groove 202. The sleeve 7 slides along the axis of the connecting block 1 and presses the top of the guide rod 301 inward. The magnet 4 is attracted to the housing 201. The limiting block 302 is in the slot 207 on the U-shaped hook 205. The limiting block 302 locks and limits the U-shaped hook 205.

[0042] This application discloses a connection method for a quick-connect coupling for offshore wind power mooring anchor chains, comprising:

[0043] Using the two quick-connect couplings for offshore wind power mooring anchor chains, the connecting block 1 of one quick-connect coupling is fixedly connected to the mooring anchor chain on the sea surface pillar, and the connecting block 1 of the other quick-connect coupling is fixedly connected to the mooring anchor chain of the offshore wind power floating foundation. Then, the U-shaped hooks 205 of the two quick-connect couplings can be mated and engaged, the protrusions 206 of the two U-shaped hooks 205 contact each other, and the fastening mechanism 3 locks and limits the ends of the U-shaped hooks 205, thus realizing the quick-connect coupling connection process.

[0044] The quick-connector connection process is as follows: First, adjust the angle of the U-shaped hook 205 inside the housing 201, then offset the semi-cylinders in the two housings 201, and then align them. The two U-shaped hooks 205 respectively contact the two protrusions 206 on the U-shaped hook 205, causing the U-shaped hooks 205 to rotate around the rotating shaft 204, so that the two U-shaped hooks 205 are in an interlocking state. Then, pull the magnet block 4, causing the sleeve 7 to extend from the connecting block 1 and engage the guide rod 301 exposed on the outer surface of the housing 201. The compression force causes the spring 303 to contract, and the guide rod 301 moves towards the U-shaped hook 205. The limiting block 302 moves within the second limiting groove 203 and abuts against the U-shaped hook 205. The outer surface of the limiting block 302 fits against the slot 207, completing the fastening. During the movement of the two magnet blocks 4, they come into contact with each other and, under the action of magnetic force, form a closed protection for the quick-connect mechanism 2 on the two joints, completing the quick connection. The joint structure is simple, easy to manufacture and operate, and suitable for various types of offshore wind power mooring anchor chains.

[0045] The anchor chain is first fixedly connected to the quick-connect coupling of the offshore wind power mooring anchor chain, and then the anchor chains are docked together through the quick-connect coupling. During docking, the two U-shaped hooks 205 are in an interlocking state, causing the spring 303 to contract. The guide rod 301 moves towards the U-shaped hook 205, and the limiting block 302 moves in the second limiting groove 203 to abut against the U-shaped hook 205. This avoids the use of threaded connection and solves the problem that the threads of offshore threads are prone to rust, which leads to the failure of the shackle rotation thread and prevents quick docking.
