[0002] Floating offshore wind power towing refers to the operation of using a tugboat to tow floating offshore wind power equipment for long-distance navigation at sea. The main purpose is to transport offshore wind turbines to designated sea areas.

[0003] The tow cable used to tow an offshore wind turbine is crucial in the towing process, serving as the crucial connection between the tugboat and the towed object. The tow cable must possess excellent tensile strength, abrasion resistance, and corrosion resistance. These properties ensure that the tow cable does not break or wear during towing, and can withstand various harsh marine environments. However, due to the complex and ever-changing conditions at sea, in an emergency, the tow cable must be disconnected to release the connection between the tugboat and the towed object. Existing tow cable connections utilize a rotating unhitch or a hanging cable (see Chinese Patent Publication No. CN212473816U), which is not convenient for quick disconnection and affects the reliability of the tow cable disconnection in an emergency.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0023] like Figures 1 to 5 shown.

[0024] A tow cable quick disconnect device of the present application comprises:

[0025] The connecting column 1 is fixed on a tugboat or a floating offshore wind power device, and is in a fixed state when in use.

[0026] The middle of the connecting column 1 is fixedly connected to a fixing frame 12, the middle of the fixing frame 12 is slidably connected to a connecting frame 13, the middle of the connecting frame 13 is rotatably connected to a load-bearing rod 14, the middle of the fixing frame 12 is provided with a socket 15 for inserting the load-bearing rod 14, and the middle of the load-bearing rod 14 is covered with a tow cable 16.

[0027] During operation, the towline 16 is placed on the load-bearing rod 14, and then the connecting frame 13 is slid upward to insert the load-bearing rod 14 into the socket 15 of the fixing frame 12. When the floating offshore wind turbine is towed, the towline 16 is tightened and pulls the load-bearing rod 14 and the connecting frame 13, which greatly increases the friction between the connecting frame 13 and the fixing frame 12, so that the connecting frame 13 will not easily slide down and the load-bearing rod 14 will be disengaged from the socket 15. When an emergency situation arises and the towline 16 needs to be quickly disconnected to release the towing state, the connecting frame 13 is struck and forced to drop, and the load-bearing rod 14 is disengaged from the socket 15. The load-bearing rod 14 rotates to quickly disconnect the towline 16. Through the above structure, the connection state of the towline 16 can be quickly released in the event of an emergency during towing, thereby quickly separating the ship from the offshore wind turbine to cope with the emergency. This solves the problem that the existing technology is not convenient for quickly disconnecting the towline, which affects the reliability of the towline disconnection in an emergency.

[0028] The middle part of the fixed frame 12 is rotatably connected to the conduction lever 2, and a pair of fixed support rods 21 are fixedly connected to the bottom of the fixed frame 12. The bottom end of the fixed support rod 21 is connected to a rotatable pulley 22, and a connecting rope 23 is provided on the pulley 22. The connecting rope 23 rotates relying on the pulley 22; one end of the connecting rope 23 is fixed to the bottom of the connecting frame 13, and the other end of the connecting rope 23 is fixed to the bottom of the conduction lever 2 near the connecting frame 13; the conduction lever 2 rotates on the fixed frame 12, pulling the connecting frame 13 downward with the connecting rope 23.

[0029] During operation, when it is necessary to disconnect the towline 16, the end of the conductive lever 2 away from the connecting frame 13 is knocked downward. Under the action of the lever principle, the fixed frame 12 pulls the connecting frame 13 down through the connecting rope 23, thereby driving the load-bearing rod 14 on the connecting frame 13 to descend, so that the towline 16 is separated from the load-bearing rod 14. Since the conductive lever 2 is a lever structure, the connecting frame 13 can overcome the greater friction force to descend. Through the above structure, the disconnection operation of the towline 16 can be made more labor-saving, and the occurrence of difficulties in disconnecting the towline 16 caused by the large friction resistance between the connecting frame 13 and the fixed frame 12 can be reduced.

[0030] A slidable slider 3 is connected to the middle of the fixed frame 12. A bevel block 31 is fixed to the bottom of the slider 3. A push rod 32 is fixed to the top of the guide lever 2 near the connecting frame 13, and the push rod 32 is locked in contact with the bevel block 31. The slider 3 is stuck between the connecting frame 13 and the fixed frame 12. Under normal circumstances, the slider 3 restricts the connecting frame 13 from sliding downward on the fixed frame 12. When the conductive lever 2 rotates, the push rod 32 presses the bevel block 31, and the slider 3 is forced to slide away from between the fixed frame 12 and the connecting frame 13, releasing the sliding restriction on the connecting frame 13. The conductive lever 2 continues to rotate, and the connecting rope 23 becomes taut from being loose, pulling the connecting frame 13 downward. With this structure, the connecting frame 13 can be prevented from sliding downward when the towline 16 does not need to be disconnected, thereby reducing the possibility of the connecting frame 13 sliding downward and causing the towline 16 to be accidentally disconnected.

[0031] The end of the fixed frame 12, away from the connecting frame 13, is provided with a through-hole through which a slidable sliding rod 4 is mounted. A lifting rod 41 is fixed to the top of the sliding rod 4. The sliding rod 4 is sheathed with a spring 42 and abuts against the fixed frame 12. The lifting rod 41 contacts the bottom surface of the conductive lever 2. When the conductive lever 2 does not need to rotate significantly to pull the connecting frame 13 downward, the lifting rod 41 abuts the conductive lever 2, thereby reducing the possibility of repeated collisions between the lifting rod 32 and the inclined block 31 due to the swaying of the ship, which would cause the inclined block 31 to move the slider 3. This, in turn, reduces the possibility of the slider 3 accidentally detaching from the fixed frame 12 and the connecting frame 13, further reducing the possibility of accidental disconnection of the towline 16.

[0032] A fixing plate 7 is fixed to the end of the conductive lever 2 away from the connecting frame 13; a fixing cylinder 5 is fixed to the side wall of the connecting column 1 above the fixing plate 7, and a supporting plate 51 is rotatably connected inside the fixing cylinder 5. A through slot 52 is opened on the side wall of the fixing cylinder 5, and the end foot of the supporting plate 51 extends into the through slot 52. The supporting plate 51 rotates downward on the side away from the through slot 52. Figure 5 The clockwise dotted line in the middle; the side wall of the fixed cylinder 5 is fixed with an elastic rod 53, the bottom end of the elastic rod 53 is fixedly connected to the limit rod 54, the limit rod 54 is against the end foot of the supporting plate 51, and there is a weight 55 inside the fixed cylinder 5, and the weight 55 is on the supporting plate 51.

[0033] The rotating supporting plate 51 uses the limiting rod 54 to limit the supporting plate 51 and makes the weight 55 be located above the supporting plate 51. When the towline 16 needs to be disconnected urgently, the limiting rod 54 can be pulled to elastically deform the elastic rod 53 so that the limiting rod 54 is away from the side wall of the fixed tube 5 and the rotation restriction of the supporting plate 51 is released, so that the weight 55 falls and hits the conductive lever 2, causing the conductive lever 2 to rotate under force and quickly disconnect the towline 16. Through the above structure, the towline 16 can be quickly disconnected in an emergency without the aid of additional tools, reducing the time waste caused by searching for tools and improving efficiency in an emergency.

[0034] A pull rope 6 is fixed to the top of the weight 55, and the pull rope 6 is detachably fixed to the top of the fixing tube 5; during operation, when the weight 55 hits the conductive lever 2, the pull rope 6 will hang the weight 55, reducing the occurrence of the weight 55 falling into the sea and reducing the waste of resources.

[0035] Working principle: When in use, put the tow cable 16 on the load-bearing rod 14, and then slide the connecting frame 13 upward to insert the load-bearing rod 14 into the socket 15. When towing the floating offshore wind turbine, the tow cable 16 is tightened and pulls the load-bearing rod 14 and the connecting frame 13, which greatly increases the friction between the connecting frame 13 and the fixed frame 12, so that the connecting frame 13 will not slide down easily to disengage the load-bearing rod 14 from the socket 15. When an emergency situation arises and the tow cable 16 needs to be quickly disconnected to release the towing state, a downward force is applied to the connecting frame 13 to lower the connecting frame 13, thereby disengaging the load-bearing rod 14 from the socket 15, and then the load-bearing rod 14 will rotate to separate the tow cable 16 from the load-bearing rod 14, thereby disconnecting the tow cable 16.
