[0046] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0047] Combination Figure 1 As shown, a permanent mooring device for a floating wind turbine provided by the present invention comprises a rotating chain jack device 1, a mooring chain 2, a chain stopper 3 and a universal chain guide 4.

[0048] The rotating chain jack device 1 and the chain stopper 3 are installed on a deck or a platform.

[0049] The universal chain guide 4 is installed on the side of the platform legs.

[0050] One end of the mooring chain 2 passes through the universal chain guide 4 and the chain stopper 3 in sequence and then is wound around the rotating chain jack device 1.

[0051] Combination Figure 2 and Figure 3 As shown, the rotary chain jack device 1 includes a bracket 11, a guide chain wheel 12, a rotary arm 13, a stopping mechanism, a pushing claw 16 and a jack 14.

[0052] The bracket 11 is installed on a deck or a platform.

[0053] The guide sprocket 12 and the rotating arm 13 are mounted on the bracket 11 through the same pin shaft 15 .

[0054] The fixed end of the jack 14 is connected to the bracket 11 , and the movable end is connected to one end of the rotating arm 13 .

[0055] The rear end of the pushing claw 16 is installed on the rotating arm 13 through the pin shaft 19 , and the front end of the pushing claw 16 is in contact with the guide chain wheel 12 .

[0056] The stop mechanism is used to prevent the guide sprocket 12 from rotating in reverse.

[0057] The stopping mechanism comprises a ratchet cylinder 17 and a ratchet 18 .

[0058] The rear end of the pawl 18 is mounted on the bracket 11 via a pin.

[0059] The ratchet cylinder 17 is mounted on the bracket 11 , and the movable end of the ratchet cylinder 17 pushes the ratchet 18 so that the front end of the ratchet 18 contacts the guide sprocket 12 .

[0060] The floating wind turbine permanent mooring device of the present invention also includes a hydraulic system for providing power to the jack 14 and the ratchet cylinder 17. A generator is used to provide power to the hydraulic system, and remote control technology is used to realize operation control of the hydraulic system.

[0061] Start the motor pump group of the hydraulic pump station, wait for the hydraulic system to run smoothly and enter the standby state, and start to gradually operate the jack 14 and the ratchet cylinder 17.

[0062] Combination Figure 4 and Figure 5As shown, the chain stopper 3 includes a mounting base plate 31 , a tongue brake 32 , a tongue brake mounting plate 33 and a pressure sensor 34 .

[0063] The mounting base plate 31 is mounted on a deck or a platform.

[0064] The pressure sensor 34 is placed on the mounting base 31 .

[0065] The tongue brake mounting plate 33 is placed on the pressure sensor 34 , and the mounting base plate 31 , the pressure sensor 34 and the tongue brake mounting plate 33 are connected together by fixing studs 35 .

[0066] The tongue gate 32 is naturally placed on the tongue gate mounting plate 33 by natural gravity, and is movably connected to the tongue gate mounting plate 33 via the tongue gate mounting shaft 36 .

[0067] A tongue brake anti-flip limiter 37 is also installed on the tongue brake mounting plate 33 by bolts to prevent the tongue brake 32 from being unable to reset after flipping.

[0068] Combination Figure 6 and Figure 7 As shown, the tongue gate 32 includes a tongue gate body 321 and a connecting rod 322 .

[0069] The rear end of the connecting rod 322 is provided with a tongue brake mounting shaft mounting hole 323 , which is movably connected to the tongue brake mounting plate 33 via the tongue brake mounting shaft 36 , and the front end of the connecting rod 322 is connected to the rear end of the tongue brake body 321 .

[0070] The front upper portion of the tongue brake body 321 is provided with a curvature groove 324 adapted to the curvature of the chain link on the mooring chain 2 , and the front lower portion is provided with an oblique angle to form a guide surface 325 .

[0071] The upper rear end of the tongue gate body 321 is set to an angle 326, which cooperates with the tongue gate mounting plate 33 to withstand the force of the mooring chain 2 to the side and below; the middle position of the lower rear end of the tongue gate body 321 is set to a chamfer 327 to fix the position of the tongue gate 32 and ensure that the tongue gate mounting shaft 36 is not subjected to force and can rotate flexibly.

[0072] Start the jack 14 and lift the rotating arm 13 so that the pushing claw 16 contacts and pushes the guide chain wheel 12, slowly lift the mooring chain 2, and after reaching the predetermined position, slowly retract the oil cylinder of the jack 14. At this time, the chain stopper 3 naturally falls back, locks the mooring chain 2, and retracts the jack 14 to the initial position. Repeat the cycle until the chain tightening process is completed. Finally, the chain stopper 3 is closed, so that the chain stopper 3 bears all the force to achieve the effect of fixing the chain.

[0073] The tongue gate 32 is naturally placed on the tongue gate mounting plate 33 by gravity. When the mooring chain 2 passes through the chain stopper 3 from bottom to top, the tongue gate 32 is naturally opened. Because of the tongue gate anti-turnover limit 37, the center of gravity of the tongue gate 32 always tilts toward the mooring chain 2. Figure 8 When the mooring chain 2 moves from top to bottom, the mooring chain 2 naturally sits on the tongue brake 32, and the entire chain stopper 3 is stressed to tighten the mooring chain 2, as shown in FIG. Fig. 9 shown.

[0074] During the chain fixing process, the ratchet cylinder 17 is started and the ratchet 18 is rotated to ensure that the guide chain wheel 12 does not reverse.
