Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a flexible dynamic submarine exploration cable. Background Art

[0002] There are various and abundant types of mineral resources in the ocean, distributed from the coast to the ocean. For example, the global submarine oil reserves are about twice the world's proven oil reserves, and the reserves of deep-sea manganese nodules and submarine hydrothermal deposits are also huge, all of which await exploration and development and utilization. In existing submarine explorations, cables are needed to connect giant equipment for exploration and excavation operations on the seabed.

[0003] In related technologies, for existing submarine exploration cables, due to the gradually increasing pressure in the deep ocean, the cables are prone to the pressure brought by various special situations and the huge tensile force when connecting submarine exploration equipment on the seabed. However, the existing submarine exploration cables have poor pressure resistance and tensile resistance effects, and are very likely to cause cable damage during exploration operations. Moreover, seawater has strong corrosiveness, and over time, the inside of the cable is easily corroded by seawater, unable to ensure the normal use of submarine exploration work, and the service life of the cable is short. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flexible dynamic submarine exploration cable to solve at least one aspect of the problems and defects mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A flexible dynamic submarine exploration cable, comprising:

[0007] A sheath layer, an armor layer is arranged inside the sheath layer, and a pressure reducing layer is arranged inside the armor layer;

[0008] A shielding layer is arranged inside the pressure reducing layer, a tape layer is arranged inside the shielding layer, and a conductor core is arranged inside the tape layer.

[0009] According to the flexible dynamic submarine exploration cable of this solution, it has at least the following technical effects:

[0010] This flexible dynamic subsea exploration cable can effectively shield electromagnetic signals through the shielding layer set outside the core, ensuring the stable transmission of the core is not interfered by the external environment. Moreover, the armor layer can improve the tensile strength of the cable, avoiding the situation of cable breakage during subsea exploration. The pressure relief layer has properties such as light weight, sound insulation, excellent heat insulation performance, and pressure resistance, which can prevent damage to the cable caused by water depth pressure during subsea exploration and affect exploration operations. At the same time, the sheath layer can effectively prevent the cable from being bumped and scratched during exploration, and has excellent chemical resistance, ensuring the corrosion resistance of the cable, reducing the corrosion degree of seawater, etc. on its surface, and increasing the service life of the cable. This cable has good pressure resistance, tensile strength, and anti-interference ability, extending the service life of the cable and being able to meet the use requirements of subsea exploration operations.

[0011] As a further solution of the present utility model: The core includes a control unit and a signal unit, and a filling unit is arranged between the control unit and the signal unit.

[0012] Since the core includes a control unit and a signal unit, it ensures the effective reception or feedback of signal data during subsea exploration, guarantees the stability of signal transmission, and controls subsea exploration equipment through the control unit according to signal instructions, improving subsea exploration efficiency.

[0013] As a further solution of the present utility model: The outer layer of the control unit is an insulating layer, and a conductor is enclosed within the insulating layer.

[0014] Since the outer layer of the control unit is an insulating layer and a conductor is provided within the insulating layer, the insulating layer effectively isolates the conductor from the external environment, preventing electrical short - circuit and leakage problems, improving the electrical safety of the cable. At the same time, it reduces the interference of external electromagnetic fields on the conductor, ensuring the stability and timeliness of the control unit.

[0015] As a further solution of the present utility model: The signal unit uses a single - mode optical fiber.

[0016] Since the signal unit uses a single - mode optical fiber, it can effectively enhance the transmission rate of signal data, avoid the influence of subsea depth on the signal transmission of the cable, and ensure the working stability and reliability of subsea exploration.

[0017] As a further solution of the present utility model: The filling unit is a water - blocking filling rope.

[0018] Since the filling unit is a water - blocking filling rope, it can effectively prevent water and gas from seeping into the cable interior, protecting the control unit and the signal unit from the influence of a humid environment, and can provide support for the control unit and the signal unit, preventing damage to the control unit and the signal unit caused by cable bending or stretching, further improving the stability and service life of the core.

[0019] As a further solution of the present utility model: the sheath layer is extruded, and the material is selected as thermoplastic elastomer.

[0020] Since the sheath layer is extruded and the material is selected as thermoplastic elastomer, it can effectively protect the internal structure of the cable from external friction and mechanical damage, and it has excellent flexibility, enabling the cable to remain stable when bent, avoiding cracks or fractures, and at the same time, it can enhance the corrosion resistance of the cable, effectively resist the erosion of chemical substances such as seawater, and improve the use stability and durability of the cable in submarine exploration.

[0021] As a further solution of the present utility model: the armor layer is wound by reinforced aramid filaments.

[0022] Since the armor layer is wound by reinforced aramid filaments, it can effectively resist large external tensile forces, protect the cable core from being easily broken, maintain the integrity of the cable during long-term use, reduce damage caused by abrasion, and improve the tensile strength and rigidity of the cable.

[0023] As a further solution of the present utility model: the pressure relief layer is a foamed silica gel tape wound.

[0024] Since the pressure relief layer is a foamed silica gel tape wound, it can effectively buffer and reduce the impact of the seabed pressure on the cable, protect the internal structure of the cable from impact and compression, ensure the safe operation of the cable in a high-pressure environment. At the same time, the foamed silica gel tape has good heat insulation performance, can better adapt to the change of the seabed environment temperature, and improve the adaptability of the cable to extreme environments or temperatures.

[0025] As a further solution of the present utility model: the shielding layer is a tinned copper wire braided layer.

[0026] Since the shielding layer is a tinned copper wire braided layer, it can effectively shield electromagnetic interference (EMI) and radio frequency interference (RFI), protect the signal transmission inside the cable from external interference, ensure the stability and clarity of signal transmission, reduce the signal loss due to long-distance submarine exploration, and improve the quality and reliability of signal transmission.

[0027] As a further solution of the present utility model: the tape layer is a water-blocking tape wound.

[0028] Since the tape layer is a water-blocking tape wound, it can effectively protect the inside of the cable from moisture intrusion. The water-blocking tape is made of materials with high water absorption ratios such as polyacrylamide and polyacrylate, which can quickly expand when encountering water, fill the gaps in the cable core, prevent the infiltration of water, and improve the water resistance and safety of the cable.
