Quick connector for tie-back of offshore wind power mooring anchor chain

Abstract

The invention discloses a quick connector for tie-back of an offshore wind power mooring anchor chain. The quick connector comprises a connecting block used for being fixedly connected with the mooring anchor chain; a rotating column is rotatably mounted in the connecting block, the rotating column can rotate around the axis of the connecting block, and a connecting column is fixed to the rotating column; and the connecting column is fixedly connected with a quick connecting mechanism. The anchor chains are fixedly connected before the offshore wind power mooring anchor chain tie-back quick connector, then the anchor chains are in butt joint through the offshore wind power mooring anchor chain tie-back quick connector, and during butt joint, the two U-shaped hooks are in an engaged shape, so that the springs contract, the guide rods move towards the U-shaped hooks, and the limiting blocks move in the second limiting grooves to abut against the U-shaped hooks. Threaded connection is avoided, and the problem that quick butt joint cannot be achieved due to failure of shackle rotating threads caused by the fact that thread teeth of offshore threads are prone to rusting is solved.

Description

Technical Field

[0001] The invention relates to an offshore wind power mooring anchor chain tie-back quick connector, belonging to the technical field of offshore wind power equipment. Background Art

[0002] Offshore wind farms usually need to fix wind turbines to the seabed through a mooring system to ensure the stability of the wind turbines under the action of wind. The anchor chain in the mooring system is an important component connecting the wind turbine to the seabed. Its safety and reliability are crucial to the operation of the entire wind farm.

[0003] The connection between the existing anchor chain and the wind turbine equipment is connected by anchor chain accessories such as shackles, but the shackle (see Chinese patent publication number CN212407278U) is connected by threads, and the threads of the threads are prone to rust at sea, resulting in failure of the shackle rotating threads and failure to achieve rapid docking.

[0033] When in use, two offshore wind power mooring anchor chain return quick connectors are used, one offshore wind power mooring anchor chain return quick connector is fixedly connected to the mooring anchor chain on the sea surface column, and the other offshore wind power mooring anchor chain return quick connector is fixedly connected to the mooring anchor chain of the offshore wind power floating foundation, and then the quick connection mechanisms 2 of the connectors are quickly connected to each other, so that the offshore wind power floating foundation is moored and fixed on the sea surface column.

[0034] The quick-connect mechanism 2 comprises a housing 201 fixed to the connecting column 5, and the housing 201 is composed of a cylinder and a semi-cylinder;

[0035] A U-shaped hook 205 is rotatably mounted on the end of the shell 201 through a rotating shaft 204, and a protrusion 206 is fixed on the inner surface of the U-shaped hook 205. The U-shaped hooks 205 of the two joints can be docked and engaged, and the protrusions 206 of the two U-shaped hooks 205 are in contact, which is similar to the docking and engagement principle of automatic hooks on trains.

[0036] 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 hand 205 with the protrusion 206; the fastening mechanism 3 includes a limit block 302 that can correspond to the slot 207 on the U-shaped hook hand 205, and the limit blocks 302 are two symmetrical upper and lower blocks; the limit blocks 302 are installed and accommodated in the second limit slot 203 of the housing 201;

[0037] The guide rod 301 is fixedly connected to the limit block 302, and the guide rod 301 is installed in the first limit groove 202 of the shell 201. The limit ring 304 is screwed and sleeved on the guide rod 301. A spring 303 is sleeved on the guide rod 301 below the limit ring 304. The two ends of the spring 303 are fixed to the second limit groove 203 and the limit block 302 accordingly. The spring 303 normally retracts the limit block 302 into the second limit groove 203, and the top of the guide rod 301 extends out of the first limit groove 202; the sleeve 7 slides axially along the connecting block 1 to press the top of the guide rod 301 to retract, the magnet block 4 is adsorbed on the shell 201, the limit block 302 is in the slot 207 on the U-shaped hook hand 205, and the limit block 302 locks the U-shaped hook hand 205 to limit.

[0038] A connection method of an offshore wind power mooring anchor chain tie-back quick connector of the present application comprises:

[0039] By using the above-mentioned two offshore wind power mooring anchor chain return quick connectors, the connecting block 1 of one offshore wind power mooring anchor chain return quick connector is fixedly connected to the mooring anchor chain on the sea surface column, and the connecting block 1 of the other offshore wind power mooring anchor chain return quick connector is fixedly connected to the mooring anchor chain of the offshore wind power floating foundation, and then the U-shaped hooks 205 of the two offshore wind power mooring anchor chain return quick connectors can be docked and engaged, the protrusions 206 of the two U-shaped hooks 205 are in contact, and the fastening mechanism 3 locks and limits the ends of the U-shaped hooks 205 to realize the quick connector connection process.

[0040] The quick connector connection process is specifically as follows: first adjust the angle of the U-shaped hook 205 in the shell 201, then make the semi-cylinders in the two shells 201 staggered, and then dock, the two U-shaped hooks 205 are respectively in contact with the two protrusions 206 on the U-shaped hook 205, drive the U-shaped hook 205 to rotate around the rotating shaft 204, so that the two U-shaped hooks 205 are in a bite state, and then pull the magnet block 4, so that the sleeve 7 extends out from the connecting block 1, and the guide rod 301 on the outer surface of the exposed shell 201 is pressed. The extrusion force is formed to shrink the spring 303, and the guide rod 301 moves toward the U-shaped hook hand 205. The limit block 302 moves in the second limit groove 203 and abuts against the U-shaped hook hand 205. The outer surface of the limit block 302 fits with the card slot 207 to complete the fastening. During the movement of the two magnet blocks 4, they come into contact with each other under the action of magnetic force, forming a closed protection for the quick connection mechanism 2 on the two joints to complete the quick connection. The joint structure is simple, easy to manufacture and operate, and is suitable for various types of offshore wind power mooring anchor chains.

[0041] The anchor chain is first fixedly connected to the offshore wind power mooring anchor chain return quick connector, and then the anchor chains are docked through the offshore wind power mooring anchor chain return quick connector. During docking, the two U-shaped hooks 205 are in a bite state, causing the spring 303 to contract, and the guide rod 301 moves toward the U-shaped hook 205. The limit block 302 moves in the second limit groove 203 and abuts against the U-shaped hook 205, avoiding the use of threaded connection and solving the problem that the thread teeth of the offshore thread are prone to rust, resulting in failure of the rotating thread of the shackle and inability to achieve quick docking.
