Description

Technical Field

[0001] The present invention relates to a dynamic submarine cable quick fixing device for offshore wind power equipment and an installation method thereof, belonging to the technical field of submarine cables. Background Art

[0002] Offshore wind power, a renewable, clean energy source, is a crucial component of the low-carbon transition. In recent years, as the development of offshore fixed wind turbines has reached saturation, offshore wind energy development has gradually shifted to deepwater areas. As a key component of offshore wind power systems, floating offshore wind turbines are an inevitable development trend. Their installation and maintenance inevitably involve the issue of securing dynamic submarine cables. Existing solutions for securing dynamic submarine cables typically utilize a protective tube installation structure. During operation, the armored steel wires are typically turned outward and then secured using multiple layers of clamping plates. Due to the inherent limitations of this anchoring structure, dynamic submarine cables are unable to withstand harsh operating environments such as waves and currents. They often fail due to fatigue and slippage of the armored steel wires, or develop gaps exposed to moisture in the seawater. This, in turn, can lead to the proliferation of attached organisms at the joints, resulting in decreased overall equipment performance, increased energy consumption, and even complete damage. These issues significantly increase the maintenance workload for offshore wind turbines, imposing significant operating costs on the wind power industry. Developing a submarine cable securing device with excellent interface stability, strong waterproofing, and good adaptability to marine biological environments has become a critical technical challenge. Summary of the Invention

[0003] The purpose of the present invention is to provide a dynamic submarine cable rapid fixing device for offshore wind power equipment to solve the above technical problems.

[0004] The technical solution for achieving the purpose of the present invention is:

[0005] A dynamic submarine cable rapid fixing device for offshore wind power equipment includes a split Haversian anchoring cylinder, a split flange, and a J-tube sleeve flange. One end of the Haversian anchoring cylinder is provided with a fixing groove, and the other end is connected to the dynamic cable. The inner diameter of the split flange is equal to the bottom diameter of the fixing groove, and the split flange is connected to the J-tube sleeve flange; the other end of the J-tube sleeve flange is connected to the J-tube; the cable conductor with the armor layer removed passes through the Haversian anchoring cylinder, and its armor layer is fixed in the Haversian anchoring cylinder. A stress change sensor is installed on the side of the cable armor layer close to the cable conductor; the J-tube is filled with a bio-inhibiting slow-release agent and is equipped with a concentration sensor. The bio-inhibiting slow-release agent is added by an automatic bio-inhibiting slow-release inhibitor adding device, and the concentration sensor is electrically connected to the automatic bio-inhibiting slow-release inhibitor adding device. The automatic bio-inhibiting slow-release inhibitor adding device and the concentration sensor are both electrically connected to the wind power equipment data center.

[0006] In the above structure, the Haversian anchor cylinder is a divisible upper and lower cylinder, with a larger center and smaller ends. The ends, where they contact the cable, are straight, while the center is roughly prismatic, with rounded corners. "Half" is a transliteration of "half," meaning it's split in half.

[0007] A dynamic submarine cable rapid fixing device for offshore wind power equipment in the present application integrates a stress change sensor in the Haversian anchoring cylinder. When the steel wire falls off or loosens, its stress change data can be collected in time and uploaded to the wind power equipment data center for processing. The operation end can track the connection stability of the cable in time and locate and troubleshoot the fault as soon as it occurs. The present application also fills the J-shaped tube with a bio-inhibitor slow-release agent and is equipped with a concentration sensor. It can remove the biological attachment phenomenon by controlling the concentration of the bio-inhibitor while avoiding the impact on the marine environment. Of the above two technical points, the former eliminates the fault problem caused by the internal line break of the cable, and the latter eliminates the cable failure problem caused by the attachment of marine organisms. The two work together to effectively improve the maintenance efficiency of the cable, reduce the operating cost of the cable, and make its application safer.

[0008] Further or optionally, in order to reduce dependence on external electricity and improve its operational stability, the stress change sensor and the concentration sensor are powered by batteries and floating photovoltaic solar panels.

[0009] Further or optionally, in order to make the installation process of the biological slow-release inhibitor more controllable and avoid disassembly and assembly of the above-mentioned dynamic submarine cable rapid fixing device during subsequent maintenance, the split flange is provided with a slow-release agent loading port, and the automatic installation device for the biological slow-release inhibitor has a drug channel, and the biological inhibitor slow-release agent is added from the drug channel.

[0010] Further or optionally, in order to improve the waterproof performance of the dynamic submarine cable quick fixing device, the gap between the armor layer of the dynamic submarine cable and the Haversian anchoring cylinder is filled with steel wire glue, and the gap between the Haversian anchoring cylinder and the dynamic submarine cable contact port is filled with marine water-blocking sealant and then covered with a heat shrink tubing.

[0011] Further or optionally, the biostatic slow-release agent component is selenate with a concentration of 5 mg / L.

[0012] Furthermore or optionally, the present application also provides a method for installing a dynamic submarine cable fast fixing device for offshore wind power equipment, using the above-mentioned dynamic submarine cable fast fixing device, characterized by comprising the following steps:

[0013] S1, reserving the length from the dynamic submarine cable fast fixing device to the floating wind turbine electrical cabinet according to the dynamic submarine cable installation position;

[0014] S2, calculating the reserved length of the submarine cable based on the length of the dynamic submarine cable quick fixing device, cutting the dynamic submarine cable until the armored steel wires are exposed, then cutting and bifurcating the armored steel wires into a fan-shaped state, then cleaning the submarine cable to remove impurities from the surface of the armored steel wires, and fitting a stress change sensor onto the armored steel wires;

[0015] S3, placing the cleaned and pre-installed stress change sensor dynamic submarine cable into a Haversian anchoring cylinder, and then closing and fixing the other one;

[0016] S4: After injecting steel wire glue into the Haversian anchor cylinder, remove bubbles and wait for it to cure. After curing, apply marine water-blocking sealant at both ends of the cylinder where it contacts the dynamic submarine cable, and then apply heat shrink tubing over the marine water-blocking sealant.

[0017] S5, fix the Haversian anchor cylinder and the top of the J-tube using the split flange and the J-tube sleeve flange;

[0018] S6, injecting bioinhibitor slow-release agent.

[0019] The above installation method is simple in steps. A biological inhibitor can be placed inside the J-type of the wet insulation structure to effectively prevent biological attachment due to the enclosed moisture inside the J-type pipe. The stress change sensor can intelligently monitor the stress changes between the steel wire and the metal glue, thereby predicting anchor failure in advance and improving maintenance efficiency for staff.

[0020] Further or optionally, in order to make the connection between parts more stable, during the installation process, unless otherwise specified, the mechanical parts are connected with bolts and screws.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects:

[0022] A dynamic submarine cable rapid fixing device for offshore wind power equipment in the present application adopts a stress change sensor integrated in a Haversian anchor cylinder to collect the stress of the steel wire at the dynamic submarine cable connection position, and adopts an automatic installation device for adding biological slow-release inhibitors in a J-tube to add biological inhibitors and control their concentration. During the operation of the dynamic submarine cable, the stress data of the submarine cable steel wire can be collected in real time and the submarine cable can be always prevented from being damaged by the attachment of marine organisms, which can greatly reduce the operating cost of the submarine cable and improve the stability and operational safety of the submarine cable.

[0023] The present invention discloses a dynamic submarine cable fast fixing device for offshore wind power equipment, which is powered by floating photovoltaic solar panels and can reduce dependence on external power and improve its operational stability.

[0024] The present invention provides a dynamic submarine cable quick fixing device for offshore wind power equipment with a split flange having a slow-release agent loading port, which can make the biological slow-release inhibitor loading process more controllable and avoid the need to disassemble and assemble the dynamic submarine cable quick fixing device during subsequent maintenance.

[0025] The present application provides a dynamic submarine cable fast Haversian anchoring cylinder filled with steel wire glue, and the connection between the Haversian anchoring cylinder and the submarine cable is filled with marine water-blocking sealant and covered with a heat shrink tubing. It has better waterproof performance and is more adaptable to the rapidly changing marine environment.

[0026] The component of the biological inhibition slow-release agent in the Haversian anchoring cylinder of a dynamic submarine cable of the present application is selenate, and the concentration is 5 mg / L.

[0027] The present application also provides a method for installing the above-mentioned Haversian anchoring cylinder for a dynamic submarine cable, which has simple installation steps and higher maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
