Description

Technical Field

[0001] This invention belongs to the field of underwater equipment protection technology, and in particular relates to a remotely controlled floating underwater robot cable protection device and operation method. Background Technology

[0002] Underwater robots (such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (UUVs) require cables to connect to surface control platforms for power transmission, data exchange, and attitude control in scenarios such as marine exploration, underwater inspection, resource development, and underwater rescue. As a core connecting component, the integrity of the cable directly determines the operational efficiency and safety of the underwater robot. Currently, the following key issues remain to be addressed in the application of underwater robot cables: 1. Significant Risk of Underwater Sinking and Scraping: Cables, due to their weight, are prone to sinking to the seabed without effective buoyancy, and may scrape against seabed reefs, gravel, sharp biological remains (such as shells and coral fragments), or man-made structures (such as underwater pipelines and pile foundations). In deep-sea operations, the rate of cable sheath damage due to sinking and scraping is high. Damage can easily lead to exposed internal conductors, short circuits, or signal interruptions. Not only is the cost of replacing the cable high each time, but the replacement process also requires work to be suspended, severely impacting project progress.

[0003] 2. Severe Wear in Land Transition Sections: In the transition section between surface platforms (such as workboats, docks, and drilling platforms) and underwater robots, cables experience prolonged contact and friction with metal supports, concrete surfaces, or ship edges. This friction is significantly increased, especially during tidal changes (leading to frequent water level fluctuations) or ship movement (affected by waves), resulting in a much higher wear rate for the cable sheath compared to stable environments. Related data shows that land friction accounts for a significant proportion of cable damage, leading to generally shorter cable lifespans, frequent replacement and maintenance, and increased operating costs and workload.

[0004] 3. Lack of Position Adjustment Capability: Existing cable protection technologies are mostly passive, such as adding rubber sheaths-corrugated pipes or metal sleeves to cables. These can only reduce wear in localized areas and cannot actively adjust the cable position. When encountering water flow impacts, tidal changes, or changes in the operating trajectory of underwater robots, cables are prone to problems such as localized sinking, excessive stretching, or entanglement. Passive protection structures are difficult to adapt to dynamically changing operating scenarios, and there is still a high risk of cable damage.

[0005] Existing technologies have not yet achieved the integrated function of "buoyancy support + remote control movement + dynamic monitoring", which makes it difficult to meet the comprehensive protection needs of underwater robot cables in complex marine and land transition environments. Summary of the Invention

[0006] In view of this, the present invention provides a remotely controlled floating underwater robot cable protection device and operation method to solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A remotely controlled floating underwater robot cable protection device includes: a buoyancy support assembly, a drive and sliding assembly, a sensing and monitoring assembly, a communication and interaction assembly, a sealing control assembly, and a power management assembly. The buoyancy support assembly is a shell made of closed-cell lightweight foam buoyancy material processed into a predetermined shape. The drive and sliding assembly includes a drive wheel, a first driven wheel, a second driven wheel, a wheel fixing bracket, and a waterproof drive component. The wheel fixing bracket is fixedly connected to the inner wall of the buoyancy support assembly. The first driven wheel and the second driven wheel are rotatably connected to the wheel fixing bracket. The waterproof drive component is fixedly installed on the... On the wheel fixing bracket, the drive wheel is installed at the output end of the waterproof drive component. The cable passes through the buoyancy support assembly and the wheel fixing bracket. The drive wheel, the first driven wheel, and the second driven wheel are circumferentially distributed to clamp the cable and are all in rolling connection with the outer wall of the cable. The communication interaction component is installed on the waterproof drive component, and the power supply management component is installed inside the sealing control component. The sealing control component and the sensing and monitoring component are both located inside the buoyancy support assembly. The drive gliding component, the sensing and monitoring component, the communication interaction component, the sealing control component, and the power supply management component are electrically connected.

[0008] Furthermore, the sealing control assembly includes a sealing pressure chamber and a main controller. The sealing pressure chamber is suspended at the bottom end of the wheel fixing bracket, the main controller is inside the sealing pressure chamber, and the power management assembly is located above the main controller. The waterproof drive component, the sensing and monitoring component, and the communication interaction component are all electrically connected to the main controller. The waterproof drive component, the sensing and monitoring component, the communication interaction component, and the main controller are all electrically connected to the power management assembly.

[0009] Furthermore, the sensing and monitoring component includes a pressure detection element, which is suspended at the bottom of the wheel fixing bracket and electrically connected to the main controller. The pressure detection element is used to detect seawater pressure and determine water depth.

[0010] Furthermore, the sensing and monitoring component also includes an attitude detection device, which is installed inside the sealed pressure chamber, above the power supply management component, and is electrically connected to the main controller. The attitude detection device is used to monitor the attitude of the equipment and cables.

[0011] Furthermore, the sensing and monitoring component also includes a travel meter, which is connected to the output end of the waterproof drive component. The communication interaction component is disposed between the waterproof drive component and the travel meter, and the travel meter is electrically connected to the main controller. The travel meter is connected to the waterproof drive component to measure the sliding travel of the equipment.

[0012] Furthermore, the power supply management component includes a power battery and a battery management system; the power battery provides power to each component; the battery management system is used to monitor battery status, manage the charging and discharging process, and ensure power supply safety.

[0013] Furthermore, the outer surface of the buoyancy material shell of the buoyancy support assembly is covered with a wear-resistant and corrosion-resistant coating.

[0014] Furthermore, the sealed pressure chamber is made of corrosion-resistant metal or high-strength composite material.

[0015] A method for operating a remotely controlled floating underwater robot cable protection device includes the following steps: S1. Equipment Installation: Check the working status of each component of the equipment, place the underwater robot cable between the drive wheel, the first driven wheel and the second driven wheel, and ensure that the cable is stably clamped; S2. System Initialization: Start the main controller; the power management component starts working, the battery management system detects the battery status and feeds the data back to the main controller; the sensing and monitoring component performs a self-test; the pressure sensor collects initial water depth data, the attitude sensor completes initial attitude calibration, and the travel meter is zeroed; the communication interaction component establishes a connection with the external control terminal or surface buoy relay; the communication interaction component's initial status data; S3. Buoyancy Adaptation: The buoyancy support assembly is a replaceable buoyancy structure. Depending on the actual working water depth and cable specifications, different buoyancy parameters of the buoyancy support assembly can be replaced to adjust the buoyancy value of the buoyancy support assembly so that the cable is suspended at the target water depth, preventing the cable from sinking to the bottom or floating excessively. S4. Remote Gliding: The operator sends a gliding command through an external control terminal. After receiving the command, the main controller controls the waterproof drive to start, and the drive wheel drives the equipment to slide along the cable. During gliding, the stroke meter collects the driving parameters of the drive in real time and calculates the gliding stroke; the attitude detection device dynamically monitors the attitude of the equipment and cable; the pressure detection device continuously detects changes in water depth. If an abnormal attitude, sudden change in water depth, or stroke deviation exceeding the preset range is detected, the main controller immediately controls the waterproof drive to stop running and triggers an alarm; at the same time, abnormal information is transmitted back through the communication interaction component. S5. Status Maintenance: During operation, the communication interaction component transmits data on equipment position, sliding stroke, cable attitude, water depth, battery status, and sealed chamber pressure according to a preset cycle; the operator adjusts the equipment distribution based on the transmitted data to ensure that the cable does not rub against seabed reefs, gravel, or land structures throughout the entire process; if the battery management system detects that the remaining battery power is lower than a preset threshold, it will promptly prompt the replacement or recycling of the equipment. S6. Operation Completed: After completing the operation, the underwater robot returns to the designated recovery point along the cable via the external control terminal, shuts down the waterproof drive components and sensing and monitoring components, disconnects the communication connection of the communication interaction components, checks the wear and tear of each component, and prepares for the next operation.

[0016] The beneficial effects of this invention are as follows: 1) Significant damage prevention effect: The buoyancy support component suspends the cable at the target position underwater, completely avoiding the cable from scratching the seabed structure. The anti-scratch coating and the drive sliding component greatly reduce the friction damage of the cable in the land transition section. Practical application has verified that the wear rate of the cable outer sheath is greatly reduced, the service life is significantly extended, the cable replacement cost in a single operation cycle is greatly reduced, and the number of operation interruptions is effectively reduced.

[0017] 2) Flexible position control: The drive sliding component supports the equipment to slide freely in both directions along the cable, and the sliding speed is adjustable; the operator can adjust the position and distribution of the equipment in real time via remote control (such as reasonably arranging multiple devices on the cable according to the operation requirements), which can flexibly adapt to the dynamic working environment such as water flow and tides, effectively avoid problems such as local cable sinking, excessive stretching or entanglement, and has high attitude control accuracy.

[0018] 3) Strong environmental adaptability: The sealing control components have a high waterproof rating and a wide operating temperature range, which can meet the needs of various underwater operation scenarios such as shallow sea, deep sea, and intertidal zone. The wheel system structure of the drive gliding component can be adapted to underwater robot cables of various diameters, and the equipment can be installed without disassembling the cable. It can be adapted to most existing underwater robot cable specifications, and the equipment modification cost is low, which facilitates promotion and application.

[0019] 4) High operation and maintenance efficiency: The communication and interaction components and the sensing and monitoring components enable real-time remote monitoring and control of equipment status, which greatly reduces the frequency of manual inspection. The low-power main controller and long-endurance power battery design reduce the frequency of equipment charging, significantly reducing operation and maintenance costs compared with traditional cable protection methods, while also reducing the workload of operators.

[0020] 5) Comprehensive safety protection: The equipment has multiple abnormal protection mechanisms, including attitude abnormality alarm, water depth change alarm, low battery alarm, etc., which can effectively avoid collisions between the equipment and seabed obstacles or other underwater equipment. The multiple protection functions of the battery management system prevent battery failure, and the sealed structure of the sealed control component ensures the safety of underwater electronic components. The equipment has a low failure rate and high safety in use. Attached Figure Description
