Description

Technical Field

[0001] This invention relates to the field of unmanned surface vessel (USV) technology, specifically to a modular display platform and display system based on an unmanned surface vessel for ocean exploration. Background Technology

[0002] In recent years, major countries around the world have been accelerating the research, development, and deployment of marine observation equipment based on unmanned surface vessels (USVs), continuously tackling technical challenges in areas such as autonomous navigation, energy propulsion, and marine exploration, and promoting their development towards intelligence. This aims to achieve low-cost intelligence gathering and battlefield support as soon as possible. The development of USVs will have a profound impact on existing naval equipment systems and maritime combat models. Semi-submersible solar-powered USVs are unmanned marine observation equipment that can autonomously or semi-autonomously navigate the ocean and perform tasks such as collecting surface meteorological information and detecting underwater temperature, salinity, and current profiles using onboard meteorological and hydrological detection payloads. With features such as long range, low development cost, high safety performance, small hull size making it difficult to detect, and strong survivability in harsh sea conditions, it is a specialized tool for conducting marine meteorological and hydrological data collection and detection missions across the entire sea area. Simultaneously, the ocean-going unmanned surface vessel (USV) is an important intelligent maritime operation equipment for marine resource exploration, hydrological data collection, marine environmental monitoring, and ocean route mapping. It possesses the characteristics of autonomous navigation, long-range detection, and unattended operation. The display platform, as the core terminal for shore-based monitoring and onboard data visualization of the USV, undertakes the real-time display of information such as navigation attitude, detection data, marine environment, and equipment malfunctions.

[0003] However, traditional semi-submersible solar-powered unmanned surface vessels have the following drawbacks: Traditional marine surveys often use large survey vessels, which present problems such as high fuel costs, high labor costs, risks to personnel's lives and health in adverse sea conditions, and difficulty in providing logistical support for long-term continuous exploration. Summary of the Invention

[0004] The purpose of this invention is to provide a modular display platform and display system based on an unmanned surface vessel for ocean exploration, in order to solve the problems mentioned in the background art, which are that traditional ocean surveys are often carried out by large survey vessels, and each voyage faces high fuel costs, high labor costs, life and health risks to personnel in the event of severe sea conditions, and difficulty in supporting long-term continuous exploration with material support.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular display platform based on an unmanned surface vessel for ocean exploration, comprising a surface vessel; An umbilical cable is fixedly installed at the bottom of the surface vessel, a hydrodynamic glider is fixedly installed at the bottom of the umbilical cable, a winch is fixedly installed at the bottom of the hydrodynamic glider, a temperature, salinity, and depth sounding cable extending to the outside is wound and connected inside the winch, a weather station, a Beidou terminal, an AIS receiver, and a near-field communicator are fixedly installed in the middle of the top of the surface vessel, a vector thruster is fixedly installed at one end of the hydrodynamic glider, a fairing is fixedly installed at one end of the winch, and a multi-beam ADCP is fixedly installed on the surface of the winch; The surface vessel includes a hull and a solar panel. The top of the hull is fixedly connected to the bottom of the solar panel. A tail rudder is fixedly installed on one side of the bottom of the hull. An aircraft cabin unit and a deck unit are fixedly installed on both sides of the top of the hull, respectively. The hydrodynamic glider includes a hydrodynamic frame and two hydrodynamic blade groups. The top two sides of the hydrodynamic frame are fixedly connected to the bottom ends of the two hydrodynamic blade groups, respectively. A shock-absorbing and buffering mechanism is fixedly installed in the middle of the top of the hydrodynamic frame, and an electronic compass is fixedly installed at the bottom of the hydrodynamic frame.

[0006] As a further technical solution of the present invention, a first handrail is fixedly installed on both sides of the top of the deck unit, and a lifting component is fixedly installed in the middle of the top of the deck unit.

[0007] As a further technical solution of the present invention, a second handrail is fixedly installed on both sides of the top of the aircraft cabin unit, and a handle-laden cable bollard is fixedly installed on the surface of the hull.

[0008] As a further technical solution of the present invention, the umbilical cable includes two watertight connector spring cables, two load-bearing structural units, and a flexible armored cable. One end of each of the two watertight connector spring cables is fixedly connected to one end of each of the two load-bearing structural units. The opposite ends of the two load-bearing structural units are fixedly connected to both ends of the flexible armored cable. The other end of one of the watertight connector spring cables is fixedly connected to a surface vessel, and the other end of the other watertight connector spring cable is fixedly connected to a hydrodynamic glider. The umbilical cable is a connecting structure between the surface vessel and the hydrodynamic glider, which is relevant for semi-submersible solar panels. For unmanned surface vessels (USVs), the umbilical cable is crucial for transmitting power, control, and sensor signals between the semi-submersible solar-powered USV surface vessel and the hydrodynamic glider. Since semi-submersible solar-powered USVs operate at sea year-round, the umbilical cable and its load-bearing structural units are subjected to repeated impacts and torsion under the influence of waves. In high sea states, these impacts are extremely powerful. By designing armored cables containing load-bearing steel wires and employing high-strength load-bearing structural units, the umbilical cable is capable of withstanding prolonged repeated impacts and instantaneous strong impacts, preventing damage from waves and ensuring its reliability.

[0009] As a further technical solution of the present invention, the flexible armored cable includes several PVC insulation sheaths and several copper stranded wires. The outer sides of the copper stranded wires are fixedly connected to the inner sides of the PVC insulation sheaths. A TPU rubber sheath is sleeved between the outer sides of the PVC insulation sheaths. Galvanized steel wires are fixedly installed on both sides of the inner wall of the TPU rubber sheath. The outer protective layer is made of black polyurethane material, which has the characteristics of bending resistance, corrosion resistance, and insulation. The inner layer is reinforced by Kevlar braided mesh. The load-bearing steel wire uses two galvanized steel wires with a diameter of 3.5mm as the load-bearing unit of the flexible armored cable, mainly to bear the periodic load continuously received by the umbilical cable. The stress is concentrated on the load-bearing steel wire, thus preventing the deformation of the load-bearing steel wire from being transmitted to the data power line and causing it to deform as well, leading to fatigue damage. The cable core unit, i.e., the data power line, has 2 power lines and 4 signal lines to transmit power and data signals. Twisted pair cable is used to improve the data transmission rate and reliability. The power line uses multi-strand copper wire, 0.08mm ultra-fine twisted oxygen-free copper wire per strand, with a cross-section of 0.75mm, a current of 10A, and a fluoroplastic insulation layer. The signal line uses multi-strand copper wire, 0.08mm ultra-fine twisted oxygen-free copper wire per strand, with a cross-section of 0.5mm, a current of 5A, and a fluoroplastic insulation layer.

[0010] As a further technical solution of the present invention, the top end of the shock absorption and buffer mechanism is fixedly connected to the umbilical cable, and one end of the hydrodynamic frame is fixedly connected to the vector thruster. The hydrodynamic blade is rotated by fixing its relative position to the hydrodynamic frame through a rotating shaft, and the water flow acts on the hydrodynamic blade to transfer the thrust to the hydrodynamic frame, thereby achieving forward movement. The rotating shaft is subjected to both the torque brought by the rotation of the hydrodynamic blade and the bending moment brought by the water flow impacting the hydrodynamic blade. In order to ensure that the hydrodynamic blade does not damage the original streamlined airfoil after being installed on the hydrodynamic glider, a metal tube sleeve is embedded in the end face of the hydrodynamic blade and a through hole with a groove is machined on the surface. The rotating shaft is also threaded in the corresponding position. After the rotating shaft is tightly fitted and installed, it is fixed with screws and self-locking nuts to ensure that the rotating shaft and the blade do not loosen or slip during the movement.

[0011] As a further technical solution of the present invention, the shock absorption and buffering mechanism includes a shock absorption box and a frame beam. The top end of the shock absorption box is fixedly connected to the bottom end of the frame beam. A universal joint is fixedly installed on the top end of the frame beam. Several guide rods extending into the frame beam are fixedly installed inside the shock absorption box. Bottom pads are laid at the connection points between the guide rods and the shock absorption box. Several combined disc springs located outside the guide rods are fixedly installed inside the shock absorption box. The bottom end of the shock absorption box is fixedly connected to the hydrodynamic frame. The top end of the universal joint is fixedly connected to the umbilical cable. Under extreme sea conditions, the periodic load on the hydrodynamic glider is greatly affected by wave fluctuations. In order to improve its periodic load-bearing capacity, a shock absorption and buffering mechanism is designed at the connection points between the surface vessel and the hydrodynamic glider and the umbilical cable support point, respectively. A shock absorption and buffering structure based on combined disc springs is proposed, which enables the hydrodynamic glider to have strong buffering and vibration absorption capacity when subjected to impact loads.

[0012] As a further technical solution of the present invention, the vector thruster includes a housing and a hub. One end of the housing is rotatably connected to one end of the hub. A mounting base is fixedly installed on the other side of the housing. A watertight connector is fixedly installed in the middle of the mounting base. A brushless motor is fixedly installed inside the housing. The output end of the brushless motor is fixedly connected to the end of the hub directly opposite to it. One side of the housing is fixedly connected to the hydrodynamic glider. The vector thruster adopts a magnetic coupling sealing method, has a two-bladed propeller, is right-handed, has an outer diameter of 300mm, uses PWM control, has a forward thrust of 5KG, and the housing is made of titanium alloy, weighing 3.8KG. When the propeller rotates, the reverse thrust of the fluid causes the blades to unfold, propelling the semi-submersible solar-powered unmanned surface vessel forward. When the propeller stops, the forward movement of the hydrodynamic glider causes the blades to fold naturally, reducing drag.

[0013] A display system based on a modular display platform for ocean-going unmanned surface vessels (USVs) includes a navigation attitude display screen, a detection data display screen, an environmental monitoring display screen, a fault alarm display screen, and several backlight brightness adjustment components. The navigation attitude display screen, the detection data display screen, the environmental monitoring display screen, and the fault alarm display screen are arranged independently, and the several backlight brightness adjustment components are respectively embedded inside the navigation attitude display screen, the detection data display screen, the environmental monitoring display screen, and the fault alarm display screen.

[0014] As a further technical solution of the present invention, the bottom ends of the navigation attitude display screen, the detection data display screen, the environmental monitoring display screen, and the fault alarm display screen are all fixedly connected to the surface vessel.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This device utilizes new technologies such as artificial intelligence autonomous navigation control, new energy sources, satellite communication, and marine big data. It employs small, low-power unmanned survey vessels, saving significant costs and reducing the risk of personnel injury. Furthermore, by combining new energy technologies such as solar, wind, and energy storage batteries, it extends the range and operational time, and is not constrained by insufficient logistical support capabilities, thus achieving better economic benefits and military effectiveness.

An aircraft cabin unit 105 and a deck unit 102 are fixedly installed on both sides of the top of the hull 101, respectively. The hydrodynamic glider 7 includes a hydrodynamic frame 71 and two hydrodynamic blade groups 72. The top two sides of the hydrodynamic frame 71 are fixedly connected to the bottom of the two hydrodynamic blade groups 72 respectively. A shock-absorbing and buffering mechanism 73 is fixedly installed in the middle of the top of the hydrodynamic frame 71, and an electronic compass 74 is fixedly installed in the bottom of the hydrodynamic frame 71.

[0021] A second handrail 108 is fixedly installed on both sides of the top of the aircraft cabin unit 105, and a handle-and-moor bollard 107 is fixedly installed on the surface of the hull 101.

[0022] The umbilical cable 6 includes two watertight connector spring cables 61, two load-bearing structural units 62, and a flexible armored cable 63. One end of each of the two watertight connector spring cables 61 is fixedly connected to one end of each of the two load-bearing structural units 62. The opposite ends of each of the two load-bearing structural units 62 are fixedly connected to both ends of the flexible armored cable 63. The other end of one of the watertight connector spring cables 61 is fixedly connected to the surface vessel 1, and the other end of the other watertight connector spring cable 61 is fixedly connected to the hydrodynamic glider 7.

[0023] In use, the umbilical cable 6 is the connecting structure between the surface vessel 1 and the hydrodynamic glider 7. It is very important for the semi-submersible solar-powered unmanned surface vessel platform, as it is used to transmit power, control, and sensor signals between the surface vessel 1 and the hydrodynamic glider 7. Since the semi-submersible solar-powered unmanned surface vessel platform operates at sea for many years, the umbilical cable 6 and the umbilical cable load-bearing structural unit 62 are subjected to repeated impacts and torsion under the action of waves. In high sea states, such impact forces are very strong. By designing an armored cable containing load-bearing steel wires and using a high-strength load-bearing structural unit 62, the umbilical cable 6 has the ability to withstand long-term repeated impacts and instantaneous strong impacts, avoiding damage to the umbilical cable 6 under the action of waves and ensuring the reliability of the umbilical cable 6.

[0024] The flexible armored cable 63 includes several PVC insulation sheaths 633 and several copper stranded wires 634. The outer sides of the several copper stranded wires 634 are fixedly connected to the inner sides of the several PVC insulation sheaths 633 respectively. A TPU rubber sheath 631 is sleeved between the outer sides of the several PVC insulation sheaths 633. Galvanized steel wires 632 are fixedly installed on both sides of the inner wall of the TPU rubber sheath 631.

[0025] In use, the outer protective layer is made of black polyurethane material, which is resistant to bending, corrosion, and insulation. The inner layer is reinforced with Kevlar braided mesh. The load-bearing steel wire uses two 3.5mm diameter galvanized steel wires 632 as the load-bearing unit of the flexible armored cable 63. Its main function is to concentrate the periodic load continuously received by the umbilical cable 6 onto the load-bearing steel wire, thereby preventing the deformation caused by the load-bearing steel wire from being transmitted to the data power line, causing the data power line to deform as well, and thus causing fatigue damage. The cable core unit, i.e. the data power line, has two power lines and four signal lines to transmit power and data signals. Twisted pair cable is used to improve the data transmission rate and reliability. The power line uses multi-strand copper wire twisted together, 0.08mm each ultra-fine twisted oxygen-free copper wire, 0.75mm cross-section, 10A current, and the insulation layer is made of fluoroplastic. The signal line uses multi-strand copper wire twisted together, 0.08mm each ultra-fine twisted oxygen-free copper wire, 0.5mm cross-section, 5A current, and the insulation layer is made of fluoroplastic.

[0026] The top of the shock-absorbing and buffering mechanism 73 is fixedly connected to the umbilical cable 6, and one end of the hydrodynamic frame 71 is fixedly connected to the vector thruster 12.

[0027] In use, the hydrodynamic blades are rotated relative to the hydrodynamic frame 71 via a rotating shaft, and the water flow acts on the hydrodynamic blades to transfer thrust to the hydrodynamic frame 71, thus achieving forward movement. The rotating shaft is subjected to both the torque from the rotation of the hydrodynamic blades and the bending moment from the impact of the water flow on the hydrodynamic blades. To ensure that the hydrodynamic blades do not damage the original streamlined airfoil after being installed on the hydrodynamic glider 7, a metal tube is embedded in the end face of the hydrodynamic blades and a through hole with a groove is machined on the surface. The rotating shaft is also threaded in the corresponding position. After the rotating shaft is tightly fitted and installed, it is fixed with screws and self-locking nuts to ensure that the rotating shaft and the blades do not loosen or slip during movement.

[0028] The shock absorption and buffer mechanism 73 includes a shock absorption box 731 and a frame beam 732. The top of the shock absorption box 731 is fixedly connected to the bottom of the frame beam 732. A universal connector 733 is fixedly installed on the top of the frame beam 732. Several guide rods 734 extending into the frame beam 732 are fixedly installed inside the shock absorption box 731. Bottom pads 736 are laid at the connection points between the guide rods 734 and the shock absorption box 731. Several combined disc springs 735 located outside the guide rods 734 are fixedly installed inside the shock absorption box 731. The bottom of the shock absorption box 731 is fixedly connected to the hydrodynamic frame 71. The top of the universal connector 733 is fixedly connected to the umbilical cable 6.

[0029] In use, under extreme sea conditions, the periodic load on the hydrodynamic glider 7 will be greatly affected by the wave fluctuations. In order to improve its periodic load-bearing capacity, a shock-absorbing and buffering mechanism 73 is designed at the connection points between the surface vessel 1 and the hydrodynamic glider 7 and the umbilical cable 6. A shock-absorbing and buffering structure based on the combined disc spring 735 is proposed, so that the hydrodynamic glider 7 has a strong buffering and vibration absorption capacity when subjected to impact loads.

[0030] The vector thruster 12 includes a housing 121 and a hub 122. One end of the housing 121 is rotatably connected to one end of the hub 122. A mounting base 124 is fixedly installed on the other side of the housing 121. A watertight connector 125 is fixedly installed in the middle of the mounting base 124. A brushless motor 123 is fixedly installed inside the housing 121. The output end of the brushless motor 123 is fixedly connected to the end of the hub 122 that is directly opposite to it. One side of the housing 121 is fixedly connected to the hydrodynamic glider 7.

[0031] In use, the vector thruster 12 adopts a magnetic coupling sealing method, a two-bladed propeller, right-hand rotation, a propeller outer diameter of 300mm, PWM control method, a forward thrust of 5KG, and a shell 121 made of titanium alloy, weighing 3.8KG. When the propeller rotates, the reverse thrust of the fluid causes the blades to unfold, propelling the semi-submersible solar-powered unmanned surface vessel forward. When the propeller stops, the forward movement of the hydrodynamic glider 7 causes the blades to fold naturally, reducing the drag of the vessel.

[0032] A display system based on a modular display platform for ocean-going unmanned surface vessels (USVs) includes a navigation attitude display screen, a detection data display screen, an environmental monitoring display screen, a fault alarm display screen, and several backlight brightness adjustment components. The navigation attitude display screen, the detection data display screen, the environmental monitoring display screen, and the fault alarm display screen are arranged independently, and the several backlight brightness adjustment components are respectively embedded inside the navigation attitude display screen, the detection data display screen, the environmental monitoring display screen, and the fault alarm display screen.

[0033] The bottom of the navigation attitude display screen, the bottom of the detection data display screen, the bottom of the environmental monitoring display screen, and the bottom of the fault alarm display screen are all fixedly connected to the surface vessel 1.

[0034] In this invention, Surface vessel 1 is a platform for installing the navigation control unit, energy supply unit, umbilical cable 6, and hydrodynamic glider 7. It also serves as a platform for carrying environmental detection equipment, providing buoyancy for the entire platform. Umbilical cable 6 is the connecting structure between surface vessel 1 and hydrodynamic glider 7. It must withstand the periodic loads of the semi-submersible solar-powered unmanned surface vessel (USV) and transmit electrical signals and data between the USV and hydrodynamic glider 7, acting as the umbilical link between them. Hydrodynamic glider 7 is the propulsion source for the semi-submersible solar-powered USV, converting wave energy into mechanical energy to provide forward propulsion for the platform.

The system uses the power controller to charge the lithium-ion battery packs and output power through the solar photovoltaic modules. The photovoltaic panels generate electricity using solar energy and store the electrical energy in the large-capacity lithium-ion battery packs through the power controller. At night or on cloudy or rainy days, the lithium-ion battery packs supply power to the platform and loads. The energy supply system is the most important part of the entire platform. To ensure the reliability and stability of the energy supply, the photovoltaic power generation modules are divided into three parts. Each photovoltaic panel supplies power to the battery packs. The three photovoltaic panels generate a total of 260W, and the battery capacity is 3.4kWh. To facilitate user installation, commissioning, and maintenance, all interfaces of the semi-submersible solar-powered unmanned surface vessel (USV) use the same physical interface for both communication and power supply.

The USV acquires its current position, motion parameters, communication status, and marine environment information such as AIS data to achieve autonomous navigation. The USV also achieves autonomous obstacle avoidance via AIS receivers and electronic nautical charts. It acquires real-time voltage, attitude, and latitude / longitude status information and uploads it to the ground station platform interface, possessing status monitoring capabilities. In emergency situations, it can activate auxiliary electric propulsion to increase speed and avoid collisions.

Satellite positioning algorithms have low requirements for the unmanned platform's own computing power and are suitable for long-endurance operation of unmanned platforms, considering low power consumption. The satellite positioning and navigation method uses nautical chart data and AIS ship information data to achieve autonomous route selection and obstacle avoidance. The calculated navigation commands correct the unmanned platform's course, making it sail toward the target point. Once the designated target point is reached, it automatically executes the task for the next target point. The system employs an intuitive user interface, enabling operators to easily monitor and control the semi-submersible solar-powered unmanned surface vessel (USV). The user interface provides real-time information display, including the USV's current battery level, latitude and longitude, speed, attitude, control mode, and mission payload parameters such as hydrological and meteorological data.
