Description

Technical Field

[0001] The utility model belongs to the technical field of marine buoy equipment and relates to a mobile disaster avoidance buoy in a marine environment. Background Technique

[0002] A buoy refers to a navigation mark floating on the water surface. It is anchored at a designated position to mark the scope of a waterway, indicate shoals, navigational hazards, or represent a waterway aid for a specific purpose. Buoys are the most numerous and widely used in navigation marks and are set in places where it is difficult or inappropriate to set up fixed navigation marks. Its function is to mark shoals in the waterway or obstacles endangering navigation safety. A buoy equipped with a lamp is called a lighted buoy and is used as a signal buoy for navigation assistance in waters with day and night navigation. Some buoys are also equipped with devices such as radar transponders, radio beacons, fog warning signals, and marine survey instruments. Buoys in the marine environment have important uses in aspects such as navigation, marine engineering, and scientific research.

[0003] Navigation Aids: Buoys mark waterways, shoals, reefs, obstacles, etc. in the ocean, providing navigation and position marking for ships. This is crucial for ships during navigation, especially at night or in bad weather conditions, and buoys can help ships ensure safe navigation.

[0004] Marine Resource Development: Buoys can mark the positions and scopes of marine resources such as offshore oil fields, fishing grounds, and submarine pipelines, providing reference and support for the development and utilization of marine resources.

[0005] Marine Monitoring and Scientific Research: Buoys can carry various sensors to monitor marine environmental parameters such as sea temperature, salinity, water depth, and ocean currents, providing data support for marine scientific research and also contributing to the monitoring and protection of the marine environment.

[0006] Marine Safety: Buoys can mark safe waters and dangerous waters, warning ships to avoid dangerous areas and ensuring marine traffic safety. In addition, buoys can also serve as markers for rescue and emergency assistance, helping those in distress at sea obtain timely help.

[0007] Marine Geographic Information Collection: Buoys can carry geolocation devices to record the longitude and latitude information of specific positions in the ocean, which is used to produce marine geographic information products such as nautical charts and navigation charts, providing basic data for navigation and marine resource development.

[0008] Buoys in the marine environment play an important role in aspects such as navigation safety, marine resource development, scientific research, and marine environmental protection, and are one of the important tools for marine management and utilization.

[0009] However, traditional surface buoys usually have a static structure. They are anchored or fixed in a certain position in the ocean, lacking flexibility and automation functions, and unable to actively respond to disaster risks in the marine environment. Summary of the Invention

[0012] An electric winch is installed at the lower part of the fully watertight sealed cabin. A winding rope is wound around the winch drum of the electric winch. The free end of the winding rope is connected with a counterweight. The gravity of the counterweight is greater than the buoyancy of the fully watertight sealed cabin.

[0023] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0024] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Figures 1-3 It includes a propulsion component 1, a first thruster 11, a second thruster 12, a bracket 13, a counterweight 2, a fully watertight sealed cabin 3, a power winch 4, a chassis frame 5, etc.

[0026] Such as Figures 1-3 As shown, the present utility model is a mobile disaster avoidance buoy in a marine environment. Aiming at the problems of insufficient flexibility and weak risk resistance of existing traditional buoys, its flexibility is enhanced by modifying the buoy floating body into a watertight cabin plus a propulsion device. By installing an automatic winch, it can quickly float and dive on the water surface and underwater, improving its risk resistance ability, thereby effectively improving the survival ability of the buoy in the marine environment. And according to different application scenarios such as marine scientific research, marine monitoring, and resource development, corresponding functional modules can be carried to achieve modular expansion and improve its scene adaptability.

[0027] The technical solution of this application includes a fully watertight sealed cabin 3. A set of propulsion components 1 are respectively arranged at the four top corners of the fully watertight sealed cabin 3. The propulsion component 1 can realize the vertical lifting adjustment and course adjustment of the fully watertight sealed cabin 3.

[0028] An electric winch 4 is installed at the lower part of the fully watertight sealed cabin 3. A winding rope is wound around the winch of the electric winch 4, and the free end of the winding rope is connected to the counterweight 2. The gravity of the counterweight 2 is greater than the buoyancy of the fully watertight sealed cabin 3. It can be understood that the electric winch 4 includes a driving motor and a rotating actuator. The heavy object 2 hanging at the lower part of the winding rope is used to drag the whole buoy to sink underwater and achieve bottom sitting during deployment. At this time, the heavy object 2 sinks to the bottom and is fixed at a certain position. The buoy floats at a certain distance above the counterweight 2 and is in a hidden state underwater. When the buoy needs to float on the water to perform operations, the electric winch 4 is triggered, the motor rotates to drive the actuator to release the rope, and the buoy floats up by its own buoyancy.

[0029] The fully watertight sealed cabin 3 is installed on the upper surface of the chassis frame 5, the electric winch 4 is installed on the bottom surface of the chassis frame 5, and four groups of propulsion components 1 are evenly distributed on the edge of the chassis frame 5.

[0030] The propulsion component 1 includes a first thruster 11 and a second thruster 12. The propulsion direction of the first thruster 11 is the vertical direction, and the propulsion direction of the second thruster 12 is towards the outside and is inclined to control the course of the fully watertight sealed cabin 3. The thrust generated by each second thruster 12 realizes the smooth navigation of the fully watertight sealed cabin 3. The first thruster 11 and the second thruster 12 have the same structure and both include an impeller driven by a motor.

[0031] As Figure 3 shown, the first thruster 11 and the second thruster 12 are respectively installed on the bracket 13. The bracket 13 is configured in a V shape. One side of the V-shaped bracket 13 is fixedly connected to the chassis frame 5, and the other side is used to install the second thruster 12. The first thruster 11 is installed on the top surface of the bracket 13.

[0032] The axes of two adjacent second thrusters 12 are perpendicular to each other. The propulsion component 1 realizes full-degree-of-freedom propulsion by using multiple second thrusters 12. Each second thruster 12 faces a different direction to provide omnidirectional movement ability and higher position control accuracy. Combined with the Beidou communication module and the geomagnetic sensor, the system can receive and calculate the accurate position and heading angle of the buoy in real time.

[0033] The four propulsion components 1 are evenly distributed on the edge of the chassis frame 5. Each second thruster 12 points in a different direction of the chassis frame 5, forming a symmetric cross layout. The angle between two adjacent second thrusters 12 is 90 degrees, ensuring the balanced distribution of thrust, improving maneuverability and response speed. The second thruster 1 not only faces outwards but also tilts at a certain angle to more effectively control and adjust the course of the buoy. The forces generated by all the second thrusters 1 pass through the center point of the chassis frame. This design reduces the energy loss during rotation and improves the propulsion efficiency. This design enables the ROV to achieve omnidirectional motion control, including forward, backward, left turn, right turn, and diagonal movement.

[0034] As Figure 4 shown, in order to achieve reliable control of the operating state of the product of the present utility model during operation, a control module is installed in the fully watertight seal cabin 3. Specifically, an MCU (microprocessor) controller, a Beidou communication module, a geomagnetic sensor module, a power supply system, a data storage module, an attitude monitoring module, a climate sensor, etc. are installed in the fully watertight seal cabin 3. Among them, the Beidou communication module is used to receive satellite signals, calculate the accurate position data of the buoy, and send it to the MCU controller through the serial port. It can be understood that the Beidou communication module includes a Beidou receiver, and the Beidou receiver is provided with an antenna interface, a power interface, and a serial communication circuit; the geomagnetic sensor module is used to measure the intensity and direction of the geomagnetic field, and transmit the data to the MCU controller through the I2C / SPI interface. The geomagnetic sensor module includes a three-axis magnetometer, an I2C / SPI interface circuit, and a temperature compensation circuit; the MCU controller is used to process the data from Beidou and the geomagnetic sensor, combine the data of the attitude monitoring module, and calculate the heading angle of the buoy. In order to achieve the above functions, the MCU controller includes a CPU core, GPIO general-purpose input and output, a Beidou communication UART interface, an SPI / 2C peripheral interface, and an ADC (analog-to-digital converter); the data storage module is used to store position data and heading angle data, SPI Flash storage, and an SD card slot; the power supply system provides stable power for the entire system. The power supply system includes a battery pack, a power management chip, a voltage conversion circuit, a voltage stabilization circuit, and an overvoltage / undervoltage protection circuit; the climate sensor is mainly used for scientific research and environmental monitoring. When conducting scientific research, the data collected by the climate sensor provides valuable information for marine scientists, helping them deeply study the interaction mechanism between the ocean and the climate, the dynamic changes of the marine ecosystem, and the impact of the ocean on global climate change; environmental monitoring mainly detects the changes of marine environmental parameters in real time, and can timely discover environmental problems such as marine pollution and ecological damage, providing a scientific basis for marine environmental protection and governance; in addition, the climate sensor also has a function of forecasting and early warning. It mainly combines the climate sensor data and the ocean model to predict the future change trend of the marine environment, providing early warning services for activities such as maritime transportation, fishery production, and marine resource development; the climate sensor includes a salinity sensor, a temperature sensor, a humidity sensor, a marine current sensor, and a depth sensor (pressure sensor); the attitude monitoring module includes a three-axis accelerometer, a three-axis gyroscope, and an I2C / SPI interface circuit. An indicator light is also installed on the fully watertight seal cabin 3.

[0035] The utility model has the following advantages: Reaction speed: Traditional surface buoys usually cannot quickly respond to changes in the marine environment. When encountering natural disasters such as storms and typhoons, traditional buoys cannot adjust their positions or take measures in a timely manner, resulting in the failure of channel markers and vessels being unable to obtain timely and safe navigation information. In contrast, the buoy of the utility model is equipped with an advanced sensor system and an automatic control function, which can monitor changes in the marine environment in real time and quickly adjust its own position and direction when a disaster risk appears to ensure the safety of maritime navigation.

[0036] Flexibility: The position of traditional surface buoys is usually fixed and cannot be flexibly adjusted or moved. This means that when the marine environment changes, traditional buoys cannot avoid risk areas autonomously and can only passively withstand the impact of storms or typhoons. In contrast, the buoy of the utility model is equipped with an automatic winch system and a propulsion device, which can flexibly adjust the depth and position of the buoy, enabling it to avoid disaster risks in a timely manner and improving the safety and disaster response capabilities of vessels and offshore facilities.

[0037] Need for manual intervention: Traditional surface buoys usually rely on manual inspections and maintenance to ensure their normal operation. This means that during a disaster, personnel need to take risks to go to the scene for maintenance and repair, increasing personnel safety risks and maintenance costs. In contrast, the buoy of the utility model has an automatic function and can avoid disaster risks without manual intervention, reducing personnel safety risks and maintenance costs.

[0038] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the utility model and not to limit them. Although the utility model has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the utility model, and they should all be covered by the scope of the claims of the utility model.
