Description

Technical Field

[0001] The present invention relates to an intelligent fault early warning device for a floating offshore wind power semi-submersible buoy foundation, belonging to the technical field of offshore wind power construction. Background Art

[0002] When the water depth exceeds 50 meters, the floating foundation uses an anchoring system to anchor the floating structure to the seabed. This serves as the foundation for installing the wind turbines, offering the advantages of low cost and easy transportation. The anchoring system plays a key role in the daily operation of the semi-submersible wind turbine foundation.

[0003] The anchoring system works by connecting a semi-floating foundation to a submarine cable foundation via multiple cables. Whenever the semi-floating foundation is subjected to external stresses such as waves and wind, the cables pull the foundation to prevent it from shifting or toppling. However, because the cables serving as the anchoring system are located below the sea surface, slackening or breaking of a single cable can be difficult for staff to detect in a timely manner. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an intelligent fault warning device for a floating offshore wind power semi-submersible floating body foundation.

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

[0006] The present invention provides a floating offshore wind power semi-submersible floating body foundation intelligent fault warning device, comprising:

[0007] An early warning device that can provide early warning of slack or breakage of the traction rope.

[0008] The early warning device includes an early warning box fixedly installed on the seabed during construction;

[0009] A movable block is slidably installed inside the warning box, and the movable block is connected to a traction rope, which passes through the warning box and is connected to a semi-submerged floating foundation;

[0010] A clamping block is fixed to the side wall of the movable block, a slide groove is provided in the warning box to accommodate the clamping block, and the clamping block is provided with a first clamping groove; a clamping box is fixed to the side wall of the warning box, and the clamping box is provided with a second clamping groove; a fixing rope is also included, and the fixing rope corresponds to the size of the first clamping groove and the second clamping groove. The clamping block is pulled up by the traction rope, and the fixing rope is clamped in the first clamping groove and the second clamping groove; an early warning float is fixed to the top of the fixing rope;

[0011] The bottom of the movable block is fixedly connected to the early warning box via a return spring.

[0012] A first fixed block is fixedly connected to the bottom of the warning box; the first fixed blocks are arranged in a circular array in multiple arrangements; a connecting rod is fixed to the bottom of the first fixed block, and the connecting rods are arranged in a circular array in multiple arrangements, with each connecting rod corresponding to a first fixed block; stirrups are fixed on the outer side walls of the multiple connecting rods.

[0013] The traction rope passes through the early warning box and is connected to the semi-submerged floating foundation through a tension meter; the traction rope is fixedly connected to the movable block through the second fixed block.

[0014] An early warning block is fixed on the top of the early warning float, a smoke transmitter is arranged inside the early warning block, and an early warning signal light is fixed on the top of the early warning block.

[0015] A limit block is fixed on the side of the movable block relative to the clamping block, and the limit block is set corresponding to the size of the clamping block; two relative limit rods are fixedly connected to the inside of the warning box, and the two limit rods are slidably matched with the clamping block and the limit block; the inner wall of the warning box is provided with a sliding groove for the limit block to slide up and down.

[0016] Buffer pads are installed at two locations in the warning box corresponding to the clamping block and the limiting block. The buffer pads are provided with through grooves for the limiting rod to pass through without contact.

[0017] A sleeve is installed on the top of the early warning box, and the traction rope passes through the sleeve on the top of the early warning box.

[0018] The beneficial effects of the present invention are as follows: when the traction rope becomes loose or broken, the movable block brings the clamping block downward, and the fixed rope is clamped from the contact between the first clamping groove and the second clamping groove. The sea water brings the early warning float to swing, so that the fixed rope is separated from the clamping box. The early warning float floats to the sea surface and is discovered to achieve the early warning effect, which solves the problem that it is difficult for the staff to discover the looseness or breakage of the cable in time.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0025] like Figures 1 to 4 shown.

[0026] The present application provides a floating offshore wind power semi-submersible floating body foundation intelligent fault warning device, comprising:

[0027] The warning box 3 is fixed to its bottom with a first fixing block 4. Multiple first fixing blocks 4 are arranged in a circular array. Connecting rods 5 are fixed to the bottom of the first fixing blocks 4. These connecting rods 5 are arranged in a circular array, with each connecting rod 5 corresponding to one of the first fixing blocks 4. Stirrups 6 are fixed to the outer walls of the connecting rods 5, and the stirrups 6 are sized to match the connecting rods 5. The mounting assembly, consisting of the first fixing blocks 4, connecting rods 5, and stirrups 6, secures the warning box 3 to the seabed foundation. The connecting rods 5 have curved bottoms, ensuring a more secure connection to the reinforced structure of the seabed foundation. The stirrups 6 attached to the side walls of the connecting rods 5 increase the contact area between the mounting structure and the concrete. The first fixing blocks 4, connecting rods 5, and stirrups 6 strengthen the connection between the connecting rods 5 and the warning box 3. This step secures the device to the seabed foundation by attaching the first fixing blocks 4, connecting rods 5, and stirrups 6. This helps prevent the device from falling off due to the pull rope 1, improving its stability and practicality.

[0028] A movable block 9 is slidably installed inside the warning box 3, and the movable block 9 is connected to a traction rope 1. After the traction rope 1 passes through the warning box 3, it is connected to the semi-submersible floating foundation 2 through a tension meter 20. The tension meter 20 continuously monitors the tension on the traction rope 1. Whenever the warning float 18 floats up, the fault condition of the foundation can be judged by checking the value of the tension meter 20. This step improves the flexibility and practicality of the device by setting the tension meter 20 in conjunction with the warning float 18 to perform fault warning of the offshore wind power semi-submersible floating foundation, which is conducive to reducing misjudgment and saving manpower.

[0029] The traction rope 1 is connected to the movable block 9 through the second fixed block 8, and the side wall of the movable block 9 is fixed with a clamping block 10. The warning box 3 is provided with a slide groove to accommodate the clamping block 10, and the clamping block 10 is provided with a first clamping groove 12; the side wall of the warning box 3 is fixed with a clamping box 13, and the clamping box 13 is provided with a second clamping groove 21; it also includes a fixed rope 17, the fixed rope 17 corresponds to the size of the first clamping groove 12 and the second clamping groove 21, the clamping block 10 is pulled up by the traction rope 1, and the fixed rope 17 is clamped in the first clamping groove 12 and the second clamping groove 21; the top of the fixed rope 17 is fixed with a warning float 18.

[0030] When the traction rope 1 becomes loose or broken, the movable block 9 carries the clamping block 10 downward, and the fixed rope 17 is clamped from the contact between the first clamping groove 12 and the second clamping groove 21. The sea water carries the early warning float 18 to swing, causing the fixed rope 17 to detach from the clamping box 13. The early warning float 18 floats to the sea surface and is discovered to achieve the early warning effect, which solves the problem that it is difficult for the staff to discover the looseness or breakage of the cable in time.

[0031] A warning block 19 is affixed to the top of the warning float 18. This block houses a smoke emitter and a warning light. During operation, whenever the warning float 18 reaches the water surface under its own buoyancy, the smoke emitter inside the block 19 emits smoke, and the warning light affixed to the top of the block 19 illuminates simultaneously. This simultaneous use of the smoke emitter and warning light provides a fault warning for the offshore wind turbine semi-submersible foundation, enhancing its suitability for nighttime operation.

[0032] The bottom of the movable block 9 is fixedly connected to the warning box 3 via a return spring 14. The return spring 14 provides a pulling force for the movable block 9 to overcome the seawater better.

[0033] A limit block 11 is fixed to the side of the movable block 9, opposite the clamping block 10. The limit block 11 is sized to correspond to the clamping block 10. Two opposing limit rods 16 are fixedly connected to the interior of the warning box 3, slidably engaging the clamping block 10 and the limit block 11. A groove is provided on the inner wall of the warning box 3 for the limit block 11 to slide up and down. As the movable block 9 slides up and down within the warning box 3, the clamping block 10 and the limit block 11 slide on the limit rods 16, providing guidance to prevent shaking and effectively maintaining the movement posture.

[0034] Buffer pads 15 are installed at two locations within the warning box 3, corresponding to the clamping block 10 and the limit block 11. The buffer pads 15 have through slots for the limit rod 16 to pass through without contact. The buffer pads 15 separate the contact between the clamping block 10 and the limit block 11 top surfaces and the warning box 3, providing a buffer between the clamping block 10, the limit block 11 and the warning box 3.

[0035] A sleeve 7 is installed on the top of the warning box 3, and the traction rope 1 passes through the sleeve 7 on the top of the warning box 3, avoiding direct hard contact between the traction rope 1 and the warning box 3 and reducing wear.

[0036] Working principle: During use, whenever the traction rope 1 connected between the semi-submerged floating foundation 2 and the early warning box 3 becomes loose or broken, the second fixed block 8 and the movable block 9 will lose the tension from the traction rope 1, and the reset spring 14 will drive the second fixed block 8 and the movable block 9 to move inside the slide groove through its own rebound. Along with the movement of the movable block 9, the clamping block 10 fixed on the side wall of the movable block 9 will move synchronously, and the fixed rope 17 will lose the clamping of the first clamping groove 12 and the second clamping groove 21. The sea water carries the early warning float 18 to swing, causing the fixed rope 17 to detach from the clamping box 13, and the early warning float 18 to float up. When the warning float 18 reaches the water surface under the action of its own buoyancy, the smoke emitter installed inside the warning block 19 will emit smoke, and the warning signal light fixed on the top of the warning block 19 will light up synchronously. The dynamometer 20 fixed between the traction rope 1 and the semi-submerged foundation 2 will continuously monitor the tension on the traction rope 1. Whenever the warning float 18 floats out of the door, the staff can judge the fault condition of the foundation by checking the value of the dynamometer 20. The sleeve 7 installed between the traction rope 1 and the warning box 3 avoids direct contact between the traction rope 1 and the warning box 3 by itself, thereby reducing the friction between the components.
