Technical Field
[0001] The utility model relates to the technical field of unmanned boats, in particular to an unmanned sailboat for full coverage scanning. Background Art
[0002] A sailboat is a vessel that uses wind as its main power source, usually including one or more sails and related control equipment, such as rudders, rigging, etc. Sailboats control their course and speed by manipulating the sails and rudders, and are widely used in navigation, trade, entertainment, and sports. An unmanned sailboat is a sailboat that is not manned by a person, but is navigated and controlled by a preset sailing route, an autonomous control system, or remote operation. Unmanned sailboats are usually equipped with various sensors, navigation equipment, and communication equipment, which can realize functions such as autonomous navigation, collision avoidance, and data collection. This type of ship is suitable for marine missions that require long time and long distances, such as marine scientific research, marine monitoring, and resource exploration.
[0003] The structure of an unmanned sailboat mainly includes sails, keels, hulls, keels, etc. Full coverage scanning is a way of ocean scanning. Its core concept is to conduct a comprehensive and thorough scanning coverage of the target area to ensure that every subtle area is covered. In the marine field, full coverage scanning usually involves the use of platforms such as ships, aircraft, and satellites, equipped with various sensors and equipment, to conduct continuous and systematic scanning of the marine area to obtain various marine data and information, such as marine topography, water temperature, salinity, water depth, tidal currents, and distribution of marine life. This scanning method can provide comprehensive and detailed marine information, providing important support and reference for marine resource development, environmental protection, and maritime traffic safety.
[0004] Unmanned sailboats use clean energy as power and can perform long-term maritime missions. They are suitable for long-term full-coverage scanning near my country's islands. Since the movement of unmanned sailboats is mainly affected by wind, and the wind force and direction of natural wind are random, the movement law of unmanned sailboats leads to poor turning ability, large turning radius, long turning time, and poorer maneuverability than ordinary ships. In the process of achieving full-coverage scanning, it needs to change direction frequently, which causes ordinary sailboats to spend more time in the turning process when achieving full-coverage scanning, long working time and low scanning efficiency. Therefore, the existing technology urgently needs to be further improved and enhanced. Utility Model Content

[0033] The utility model is described in detail below with reference to the accompanying drawings:
[0034] Combination Figures 1 to 5 An unmanned sailboat for full coverage scanning includes a hull 1, a steering control mechanism, a sail 2, a ship-borne radar 3, an electronic scanning sonar 4, an anemometer 5, a counterweight 6 and an electronic control unit. The hull 1 is a spindle-shaped structure that is symmetrical front and back. The front and rear ends of the hull 1 are both vertical plane structures. The lower contour line of the cross section of the hull 1 is a semi-elliptical shape. The bottom of the hull 1 is a gradually changing curved surface with a downward convex middle part. The bottom of the hull 1 is a streamlined shape that is symmetrical front and back, which can effectively reduce the resistance during navigation and keep the unmanned sailboat having the same navigation performance and stability during two-way navigation.
[0035] The top of the hull 1 is provided with an upper cover plate 11, which seals the interior of the hull 1 to prevent seawater from entering the hull under the action of waves during navigation and causing damage to the equipment of the hull 1. The top of the upper cover plate 11 is provided with a solar panel 12, and there are two groups of solar panels 12, which are symmetrically arranged on the front and rear sides of the top of the hull 1. Each group of solar panels 12 includes a plurality of regularly arranged solar panels 12, and the bottoms of all solar panels 12 are fixed to the top of the upper cover plate 11 through a mounting plate 121. The solar panels 12 convert the received solar energy into electrical energy, which is stored in a lithium battery pack 72 to power the electrical equipment and electronic components of the unmanned sailboat. The unmanned sailboat uses clean energy as power and can maintain long-term maritime missions.
[0036] The counterweight block 6 is fixedly arranged below the hull 1. Specifically, the counterweight block 6 is a cylindrical structure, and both the front and rear ends thereof are hemispherical. The counterweight block 6 is arranged horizontally below the middle of the hull 1, and the top is fixedly connected to the bottom of the hull 1 through the keel 61. During the travel of the unmanned sailboat, the keel 61 generates lateral pressure by moving in the water to offset the lateral aerodynamic force generated by the sail, thereby maintaining the stability of the sailboat.
[0037] When the unmanned sailboat is sailing, the sail is subjected to the force of wind, and the keel is subjected to the lateral pressure of seawater, which generates a capsizing moment, causing the sailboat to have a lateral capsizing tendency. This capsizing tendency will change the buoyancy center position of the unmanned sailboat, causing the center of gravity and the center of buoyancy of the sailboat to be not on the same plumb line, forming a restoring moment. The counterweight block 6 effectively lowers the center of gravity of the sailboat, increases the restoring moment, and ensures the stability of the unmanned sailboat during driving and turning. In addition, the overall appearance of the keel 61 and the counterweight block 6 is a front-to-back symmetrical structure, so that the unmanned sailboat has the same navigation performance in bidirectional driving.
[0038] The electronic control unit includes a shipboard computer 71, a lithium battery pack 72, a navigation module 73 and a communication module 74. The electronic scanning sonar 4, the shipboard radar 3, the anemometer 5 and the navigation module 73 are respectively connected to the shipboard computer 71 for communication. The shipboard computer 71 is connected to the control terminal on the shore for communication through the communication module 74.
[0039] The electronic scanning sonar 4 is arranged at the bottom of the hull 1, the shipborne radar 3 is installed at the front upper part of the hull 1, and the anemometer 5 is fixedly arranged at the rear upper part of the hull 1 through a bracket. The anemometer 5 is used to collect wind field information in real time and transmit the wind field information to the shipborne computer 17 to provide a basis for manipulating the angle of the sail 2 and control the direction of travel of the unmanned sailboat. The shipborne radar 3 is located at the front side of the sail 2 and is installed at the front upper part of the hull 1 through a vertically arranged radar pole. The shipborne radar 3 is located at the rear side of the sail 2 and is installed at the rear upper part of the hull 1 through a steel frame.
[0040] The unmanned sailboat moves in the ocean in a specified direction according to the preset target area and navigation route by receiving the navigation command issued by the navigation module 73. At the same time, the navigation module 73 is used to determine the real-time position and acceleration and other motion information of the unmanned sailboat. During the navigation of the unmanned sailboat, the ship-borne radar 3 detects the surrounding environmental information through electromagnetic waves to avoid obstacles. At the same time, the collected environmental information is processed by the ship-borne computer 71 and transmitted to the control terminal on the shore through the communication module 74.
[0041] The sonar 15 collects information about the seabed through full coverage scanning, and transmits the environmental information to the control terminal on the shore through the communication module 74 after being processed by the shipboard computer 71. During the execution of the scanning task, the system continuously monitors the navigation environment and task requirements, and adjusts the heading according to the real-time situation to ensure that the unmanned sailboat can efficiently complete the full coverage scanning task. During the scanning process, when the unmanned sailboat approaches an area where it needs to turn or avoid obstacles, the shipboard radar 3 will detect the corresponding heading adjustment requirements, and determine whether a turning operation is required to adapt to the task requirements based on the sensor data and the preset navigation algorithm. If turning is required, the next step is entered. When a large angle turn is required according to the navigation route, the shipboard computer 71 sends a signal to the servo motor 23 and the steering gear 83 to control the sail 2 and the rudder blade 81 to adjust the angle to slow down the unmanned sailboat. When the unmanned sailboat stops moving, the angle of the sail 2 and the rudder blade 81 is adjusted again to make the sailboat move in the opposite direction without the need for complex turning actions, thereby improving the maneuverability and flexibility of the unmanned sailboat.
[0042] The sail 2 is vertically arranged above the hull 1, and the lower end thereof passes through the upper cover plate 11 and is connected to the steering drive device arranged inside the hull 1. The sail 2 comprises a sailboard 21 and a mast 22, wherein the sailboard 21 is a rectangular structure with a symmetrical airfoil cross section, and the mast 22 is vertically arranged inside the sailboard 21 and fixed thereto as a whole, and the lower end of the mast 22 extends to the inside of the hull 1, and the circumferential surface thereof is rotationally sealed with the upper cover plate 11.
[0043] The steering drive device is installed inside the hull 1 through a fixing frame 13, and the lower end of the mast 22 is rotationally matched with the fixing frame 13 through a thrust bearing. The steering drive device includes a servo motor 23 and a transmission assembly, and the transmission assembly includes a worm wheel 24 and a worm 25. The worm wheel 24 is fixedly sleeved on the lower part of the mast 22, and the worm 25 is longitudinally and horizontally arranged on the right side of the worm wheel 24 and meshed with the worm wheel 24. The front and rear ends of the worm 25 are rotationally matched with the fixing frame 13.
[0044] The servo motor 23 is located at the rear side of the worm 25 and is fixedly mounted on the fixing frame 13. The rear end of the worm 25 is coaxially fixedly connected to the output shaft of the servo motor 23. The servo motor 23 is powered by the lithium battery pack 72. The signal end of the servo motor 23 is connected to the shipboard computer 71 for communication. In the working state, the servo motor 23 drives the mast 22 to rotate clockwise or counterclockwise through the worm gear 24 and the worm 25. During the navigation process, the anemometer 5 monitors the direction and wind speed of the sea surface in real time, and transmits the wind speed and wind direction information to the shipboard computer 71. The shipboard computer 71 controls the output shaft angle of the servo motor 23 through instructions. The output shaft of the servo motor 23 drives the worm gear 24 to rotate clockwise or counterclockwise through the worm 25, and adjusts the angle direction of the windsurfing board 21, so that the unmanned sailboat keeps sailing according to the predetermined route.
[0045] There are two steering control mechanisms, which are symmetrically arranged at the front and rear ends of the hull 1. The steering control mechanism includes a rudder blade 81, a rudder shaft 82 and a steering gear 83. The rudder blade 81 is a vertically arranged rectangular flat plate structure, and its front side and rear side are both double-edged structures. When the unmanned sailboat is sailing, the rudder blade 81 has good water-breaking and steering capabilities.
[0046] The rudder shaft 82 is arranged vertically at the front end or rear end of the hull 1, the output end of the steering gear 83 is connected to the upper end of the rudder shaft 82, and the rudder blade 81 is connected to the lower end of the rudder shaft 82. The rudder shaft 82 is rotatably matched with the front end or rear end of the hull 1 through the bearing seat, and the upper end of the rudder blade 81 is fixedly connected with the lower end of the rudder shaft 82 by bolts through the connecting piece 84. The steering gear 83 is installed at the front end or rear end of the hull 1 through the waterproof cover 85, and its output shaft is connected to the upper end of the rudder shaft 82. The steering gear 83 drives the rudder blade 81 to rotate through the rudder shaft 82. During the driving process, the onboard computer 71 controls the output shaft of the steering gear 8 to rotate through instructions, adjusts the angle direction of the rudder blade 81, and controls the heading of the front end of the hull 1. The angle direction of the rudder blade 81 matches the angle direction of the sailboard 21 to ensure that the unmanned sailboat keeps sailing according to the predetermined route.
