Description

Technical Field

[0001] The present invention relates to the technical field of pipeline design application, and in particular to a ship magnetic field detection system. Background Art

[0002] The existing ship magnetic detection solution is to fix the magnetic field detection sensor on a fixed pile on the seabed and directly connect the cable to the magnetic field detection sensor. The cable and the magnetic field detection sensor are in direct contact with seawater, which will cause marine organisms to attach for a long time. When the underwater sensor unit fails and needs maintenance, there will be a lot of resistance when pulling the cable upward, and the cable cannot be pulled up, making maintenance difficult. Summary of the invention

[0003] In view of this, the purpose of the present invention is to increase the pipeline design so that the magnetic field detection sensor is isolated from the seawater. The pipeline is arranged under the seawater, and the sensor and cable are in the pipeline. When maintenance is needed, a winch is used to pull up the cable and sensor unit in the pipeline. After the maintenance is completed, the winch on the other side is used to pull it back to its original position to complete the maintenance process.

[0004] The present invention provides a ship magnetic field detection system, comprising: a pipeline, a magnetic field detection sensor, and a cable; the pipeline is formed by splicing multiple sections and laid under the seawater; the magnetic field detection sensor and the cable are inserted into the pipeline;

[0005] The pipeline is fixed by pipeline fixing piles arranged on the seabed to ensure the accurate position and direction of the pipeline;

[0006] Both ends of the pipeline are sealed to isolate the magnetic field detection sensor and the cable from seawater.

[0007] Furthermore, the magnetic field detection sensor includes a plurality of sensor units, and the plurality of sensor units are connected in series through the cable.

[0011] Furthermore, the pipeline is a U-shaped pipeline, and the U-shaped pipeline is laid in a port with shores on both sides;

[0012] Laying U-shaped pipelines is suitable for situations where there are banks on both sides. Winches are placed on both sides of the banks, and installation or maintenance is carried out by pulling cables. There are sealed end caps at both ends of the U-shaped pipeline. When the installation is completed, tighten the sealed end caps to prevent rainwater or other things from entering the pipeline.

[0013] Further, the pipeline includes a plurality of pipeline sections and a plurality of special joints, and the side surface of the special joint has a vertical plane and a horizontal plane;

[0014] Furthermore, the pipeline fixing pile has a vertical plane and a horizontal plane;

[0015] The special joint fits with the vertical plane and the horizontal plane on the pipeline fixing pile to fix the position and direction of the pipeline.

[0016] Furthermore, both ends of the pipeline are sealed by means of sealing end covers.

[0017] Furthermore, the material of the pipeline is a non-magnetic corrosion-resistant material;

[0018] Preferably, the non-magnetic corrosion-resistant material is one of alloys 3J21, 3J22, 3J23, 3YC11, 3YC15, and 3J40.

[0019] Furthermore, the pipeline sections are connected by threads and sealed by sealing rings;
