Description

Technical Field

[0001] The 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] As a renewable clean energy, offshore wind power is an important part of the low-carbon transformation route. In recent years, as the development of offshore fixed wind power platforms has entered a saturated state, offshore wind power development has gradually shifted to the deep sea. As an important component system of offshore wind power, floating offshore wind power platforms are its inevitable development trend, and their installation and maintenance process inevitably involves the fixation of dynamic submarine cables. In the existing dynamic submarine cable fixing scheme, a protective tube installation structure is generally adopted. During the operation, the armored steel wire is generally turned outward, and then fixed by a multi-layer pressing plate. Due to its own limitations, this anchoring structure makes the dynamic submarine cable unable to adapt to the harsh working environment such as waves and ocean currents. It often fails or produces wet gaps exposed to seawater due to fatigue and slippage of the armored steel wire, and then the reproduction of attached organisms leads to the overall equipment performance at the joint. Decrease, increase energy consumption or even complete damage. These problems have greatly increased the maintenance workload of offshore wind power equipment and brought huge operating costs to the wind power industry. Developing a submarine cable fixing device with good interface stability, strong waterproof ability and good adaptability to the marine biological environment has become an important technical problem that needs to be solved. Summary of the invention

[0003] The purpose of the present invention is to provide a dynamic submarine cable quick 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 quick fixing device for offshore wind power equipment comprises a split Haversian anchoring cylinder, a split flange, and a J-type tube set 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-type tube set flange; the other end of the J-type tube set flange is connected to the J-type 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, and a stress change sensor is installed on the side of the cable armor layer close to the cable conductor; the J-type tube is filled with a biological inhibitor slow-release agent and is equipped with a concentration sensor, the biological inhibitor slow-release agent is added by an automatic biological inhibitor slow-release inhibitor adding device, the concentration sensor is electrically connected to the automatic biological inhibitor slow-release inhibitor adding device, and the automatic biological inhibitor slow-release inhibitor adding device and the concentration sensor are both electrically connected to a wind power equipment data center.

[0006] In the above structure, the Haversian anchor cylinder is a cylinder that can be divided into two halves, with a larger middle and smaller ends. The two ends of the cylinder that contact the cable are straight cylinders, and the middle is a nearly prism-shaped structure with arc chamfers at the prism corners. "Half" is the transliteration of "half", which means to be divided into two halves.

[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-tube with a bio-inhibitor slow-release agent and is equipped with a concentration sensor, which can remove the biological attachment phenomenon by controlling the concentration of the bio-inhibitor while avoiding the impact on the marine environment. Among the above two technical points, the former eliminates the fault problem caused by the breakage of the internal cable line, 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 biological slow-release inhibitor installation process more controllable and avoid disassembly and assembly of the above-mentioned dynamic submarine cable rapid fixing device during subsequent maintenance, a slow-release agent installation port is provided on the split flange, and the biological slow-release inhibitor automatic installation device 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 anchor body is filled with steel wire glue, and the gap between the Haversian anchor body and the dynamic submarine cable contact port is filled with marine water-blocking glue and then coated with a heat shrinkable sleeve.

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

[0012] Further 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 in that it includes 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 installation position of the dynamic submarine cable;

[0014] S2, calculating the reserved length of the submarine cable according to the length of the dynamic submarine cable fast fixing device, cutting the dynamic submarine cable until the armored steel wire is exposed, then cutting the armored steel wire and bifurcating it into a fan-shaped state, then cleaning the submarine cable until the armored steel wire has no impurities on the surface, and putting a stress change sensor on the armored steel wire;

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

[0016] S4, after injecting steel wire glue into the Haversian anchor cylinder, perform air bubble removal and wait for curing to be completed. After curing, apply marine water-blocking sealant at the contact points between the two ends of the cylinder and the dynamic submarine cable, and then cover the outer layer of the marine water-blocking sealant with a heat shrink tube;

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

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

[0019] The above installation method has simple steps. A biological inhibitor can be placed in the J-type of its wet insulation structure, which can effectively prevent the biological attachment in the closed and humid J-type pipe. The stress change sensor can intelligently monitor the stress change between the steel wire and the metal glue, and then predict the anchor failure in advance, which makes the maintenance efficiency of the staff higher.

[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] (1) The present invention relates to a dynamic submarine cable rapid fixing device for offshore wind power equipment, which uses a stress change sensor integrated in a Haversian anchor body to collect the stress of the steel wire at the dynamic submarine cable connection position, and uses an automatic bio-slow-release inhibitor adding device to add bio-inhibitors in a J-tube 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 damage to the submarine cable caused by the attachment of marine organisms can be prevented at all times, which can significantly reduce the operating cost of the submarine cable and improve the stability and operational safety of the submarine cable.
