Abstract
Description
Technical Field
[0001] This application relates to the field of underwater measurement technology, and in particular to a flexible energy-integrated underwater measurement array cable. Background Technology
[0002] Against the backdrop of ongoing global marine resource exploration, frequent marine natural disasters, and an increasingly complex maritime security situation, underwater sensing and measurement technology, as a core means of acquiring seabed environmental information and sensing underwater situations, has been widely applied in deep-sea environmental monitoring and marine resource surveys. Especially given the current situation of frequent maritime disputes and rising maritime security risks, the role of underwater sensing and measurement technology in national maritime strategy is becoming increasingly prominent. This technology helps to build an all-weather, wide-area, and high-precision marine awareness system, possessing broad application prospects and significant strategic importance.
[0003] In some deep-sea sensing and measurement scenarios, the limited underwater power supply conditions place higher demands on the system's energy self-sufficiency. Underwater measurement arrays, due to their large measurement aperture, wide coverage, and convenient deployment and retrieval, have become an important technical means in marine sensing and monitoring. However, existing underwater measurement arrays still struggle to achieve energy self-sufficiency, relying heavily on external, bulky battery packs for power supply. Some systems also require large signal demodulation equipment. This power supply and demodulation method not only significantly increases the complexity and operation time of deployment and construction, driving up maintenance costs, but also reduces the flexibility of deployment operations, severely restricting the promotion and application value of underwater measurement arrays in the complex environments of deep-sea areas. Utility Model Content
[0004] To address the problems of insufficient energy self-sufficiency, complex deployment operations, and poor flexibility of existing underwater measurement array cables mentioned in the background art, this application provides a flexible energy-integrated underwater measurement array cable.
[0005] The flexible energy-integrated underwater measurement array cable provided in this application adopts the following technical solution:
[0006] A flexible energy-integrated underwater measurement array cable includes an underwater measurement module. The underwater measurement module includes an outer sheath cable, and the interior of the outer sheath cable has a sealed cavity. A power module, a communication module, and a sensor are installed in the cavity. The power module is electrically connected to the communication module and the sensor, respectively.
[0007] By adopting the above technical solution, the power module, communication module and sensor are integrated into a sealed cavity to form a highly integrated underwater measurement module. This enables the measurement array cable to have independent power supply, autonomous communication and environmental perception capabilities, which significantly improves the system's energy self-sufficiency and integration. It is suitable for long-term, long-distance deep-sea measurement missions and solves the technical problems of existing systems that require external power supply and have complex deployment.
[0008] Optionally, the number of underwater measurement modules can be one or more. When there are multiple underwater measurement modules, adjacent underwater measurement modules are connected end to end.
[0009] By adopting the above technical solutions and using modular design to allow measurement modules to be serially expanded, it is not only convenient to flexibly configure the array cable length and measurement density according to different tasks, but also to realize distributed data acquisition and energy management, improve the overall system's scalability and networking capabilities, and adapt to the customized deployment needs of complex sea areas.
[0010] Optionally, the outer sheath cable is a flexible hose made of high-polymer non-metallic material, which can be coiled.
[0011] By adopting the above technical solution and using polymer non-metallic flexible hoses as the outer sheath cable material, the flexibility and coilability of the array cable are enhanced, which facilitates rapid deployment and retrieval in situations where space is limited on board or in complex sea conditions, significantly improving the efficiency and safety of offshore operations.
[0012] Optionally, the outer sheath cable is a PU tube.
[0013] By adopting the above technical solution, the outer sheath cable uses PU (polyurethane) tubing, which has good pressure resistance, wear resistance, and corrosion resistance, while maintaining high flexibility and stable sealing. It can adapt to high-salt and high-pressure marine environments for a long time, improving the overall environmental adaptability and service life of the cable array.
[0014] Optionally, the cavity inside the outer sheath cable is filled with insulating liquid, and the power module, communication module and sensor are all immersed in the insulating liquid.
[0015] By adopting the above technical solution, filling the inside of the outer sheath cable with insulating liquid can not only effectively prevent seawater from seeping in and prevent short circuits in electronic modules, but also play a role in buffering, shock absorption and heat dissipation, enhancing the operational stability and system safety of the power module, communication module and sensors, and making it suitable for long-term deep-water operation.
[0016] Optionally, watertight connectors are installed at both ends of the outer sheath cable, and the watertight connectors are sealed to the outer sheath cable.
[0017] By adopting the above technical solution, a watertight head is set to achieve a sealed connection with the outer sheath cable, effectively preventing water vapor and impurities from entering the internal cavity of the outer sheath cable, ensuring the long-term airtightness and electrical stability of the module operation, and improving the reliability of underwater operation.
[0018] Optionally, it also includes internal cables that connect the power module, communication module, and sensors, and are connected to the watertight head.
[0019] By adopting the above technical solution, electrical connections between modules are achieved through internal cables, which extend to the outside through the watertight head. Data transmission and power output can be achieved while ensuring airtightness, supporting flexible docking between the array cable and external devices, and taking into account both system integration and functional openness.
[0020] Optionally, the power module is a soft battery.
[0021] By adopting the above technical solution, the soft battery can have the characteristics of high water pressure resistance, bending resistance and pressure deformation resistance. It can be directly immersed in insulating liquid without the need for an additional rigid battery compartment as a shell, so as to realize the power supply function of sensors and communication modules.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] This invention integrates the battery, sensor, and communication module inside the outer sheath cable to form a flexible energy-integrated underwater measurement module. It realizes distributed self-powering and signal demodulation functions within the cable, improving the deployment flexibility and environmental adaptability of the measurement array cable.
[0024] This invention replaces the traditional pressure-holding battery compartment with a lightweight, high-water-pressure-resistant battery, enhancing the self-sustaining capability of the array cable under high-pressure environments, simplifying the structural design, and reducing the system's dependence on external platforms and rigid structures. This gives the overall structure high flexibility, easy deployment, and energy autonomy, making it particularly suitable for complex application scenarios such as long-term deployment in deep-sea areas, resource exploration, marine monitoring, and national defense early warning. It has significant advantages in long-term stable underwater operation and high-pressure environment adaptation. Attached Figure Description

[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] As shown in the figure, this application discloses a flexible energy-integrated underwater measurement array cable, including an underwater measurement module 1, wherein, as Figure 1-2 As shown, the number of underwater measurement modules 1 is one. It is understood that in other embodiments, such as... Figure 3 As shown, there are multiple underwater measurement modules 1, and adjacent underwater measurement modules 1 are connected end to end.
[0033] The underwater measurement module 1 includes an outer sheath cable 11, which has a sealed cavity inside. A power module 12, a communication module 13, and a sensor 14 are installed inside the cavity. The power module 12 is electrically connected to the communication module 13 and the sensor 14. The cavity inside the outer sheath cable 11 is filled with an insulating liquid, which can be silicone oil. The power module 12, the communication module 13, and the sensor 14 are all immersed in the insulating liquid.
[0034] Specifically, the power module 12 is a soft battery with high water pressure resistance and the ability to withstand bending and tensile deformation. It can be directly immersed in the insulating liquid inside the outer sheath cable 11 without the need for an additional hard battery compartment as a pressure-holding shell, in order to power the sensor 14 and the communication module 13.
[0035] Specifically, the sensor 14 itself has the ability to withstand high water pressure and can be directly immersed in the insulating liquid inside the outer sheath cable 11 to measure signals such as deep-sea acoustics, water pressure, and temperature. Depending on the different measurement directions, multiple sensors 14 of different types can be placed inside the outer sheath cable 11.
[0036] Specifically, in order to protect the communication module 13, an electronic compartment is installed inside the outer sheath cable 11. The electronic compartment is resistant to high water pressure and is immersed in an internal insulating liquid to transmit the information measured by the sensor 14.
[0037] Specifically, the outer sheath cable 11 is a flexible, non-metallic polymer hose that can be coiled. Specifically, the outer sheath cable 11 can be coiled onto a cable reel, allowing for deployment during the movement of the deployment vessel, thus achieving "passing-by" deployment without stopping the vessel. More specifically, in this example, the outer sheath cable 11 is a PU tube, filled with insulating liquid. PU tubes have good flexibility, facilitating coiling, deployment, and retrieval. They are also resistant to seawater corrosion, have strong water pressure resistance, are suitable for complex underwater environments, and possess high sealing performance and mechanical strength, protecting the internal electronic components from damage.
[0038] Specifically, watertight heads 16 are installed at both ends of the outer sheath cable 11, and the watertight heads 16 are sealed to the outer sheath cable 11. Specifically, it also includes an internal cable 15, which connects to the power module 12, the communication module 13 and the sensor 14, and is connected to the watertight heads 16. The watertight heads 16 are not only used to seal both ends of the outer sheath cable 11 to prevent seawater from entering the outer sheath cable 11, but also to meet the need for connecting multiple outer sheath cables 11 end to end, and can also realize the function of signal transmission or power transmission.
[0039] During use, the underwater measurement array cable uses sensor 14 to sense and measure deep-sea acoustic, water pressure, and temperature signals in real time. The collected signal data is transmitted and sent via communication module 13 and internal cable 15. The soft battery integrated inside the underwater measurement module 1 provides stable power to sensor 14 and communication module 13 for extended periods. This achieves distributed self-powering and signal demodulation within the cable, improving the flexibility of deployment and application of the measurement array cable, expanding its application range, and solving the shortcomings of existing measurement array cables that rely on external large batteries for power supply, such as poor flexibility and deployment difficulties. In addition, the power supply for the flexible energy-integrated underwater measurement array cable uses lightweight, high-pressure-resistant batteries, eliminating the need for a battery compartment pressure shell and improving the array cable's adaptability and self-sufficiency in high-pressure environments.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
