Description

Technical Field

[0001] The present application relates to the technical field of unmanned boats, and in particular to a self-righting unmanned boat. Background Art

[0002] An unmanned ship refers to a ship that does not require direct human operation, and completes navigation tasks through autonomous navigation and various sensors. As an autonomous navigation ship, an unmanned ship can not only reduce the manpower burden, but also play an important role in many fields. For example, unmanned ship technology is widely used in environmental monitoring, search and rescue, security patrol, scientific research and exploration, underwater mapping and many other fields.

[0003] Currently, since unmanned vessels don't require direct human control and only require the necessary equipment for their intended function, most are designed as small vessels with no space for personnel. Small vessels are susceptible to high-angle heeling motions during missions, and can even capsize when subjected to brief, intense external forces such as high winds and high waves.

[0004] Regarding the above-mentioned related technologies, once the unmanned boat capsizes, it is difficult for the remote control and monitoring personnel to right the unmanned boat, which ultimately forces the navigation or operation of the unmanned boat to be terminated. Utility Model Content

[0005] In order to ensure the stable operation of the unmanned boat on the water, the present application provides a self-righting unmanned boat.

[0006] The self-righting unmanned boat provided in this application adopts the following technical solution:

[0007] A self-righting unmanned boat, comprising:

[0008] A boat base, wherein a mounting groove is provided in the boat base, and a cross-sectional area of ​​the boat base decreases from an end of the mounting groove opening to an end away from the mounting groove opening;

[0009] A ship cover is installed at the opening of the installation slot, and the ship cover is raised upward;

[0010] A mounting bracket installed in the mounting slot; and

[0011] A counterweight is mounted on the mounting frame. When the boat base is underwater, the counterweight is located below the waterline of the boat base, and when the boat cover is underwater, the counterweight is located above the waterline of the boat cover.

[0012] By adopting the above technical solution, when the base of the boat is underwater, the position of the counterweight on the mounting frame makes the center of gravity of the unmanned boat below the waterline, making the unmanned boat more stable when sailing and able to perform tasks in the water smoothly.

[0013] If a violent external force causes the upper cover of the boat to be underwater, the position of the counterweight on the mounting frame will make the center of gravity of the unmanned boat be above the waterline, making the unmanned boat extremely unstable and easy to flip over again so that the base of the boat is underwater. Therefore, when the unmanned boat is moving, even when a violent external force causes the unmanned boat to flip over, the position of the counterweight can autonomously flip the unmanned boat back over, thereby ensuring the stable operation of the unmanned boat on the water.

[0014] Optionally, a plurality of staggered edges are provided on the ship base, and a side of the staggered edge facing the opening of the installation slot is located inside the installation slot.

[0015] By adopting the above technical solution, the arrangement of the staggered edges increases the structural strength and stability of the ship base.

[0016] Optionally, the mounting frame includes a plurality of parallel partitions and side panels mounted on the partitions, the partitions are supported on the offset edges, and the counterweight is mounted on the partitions and the side panels.

[0017] By adopting the above technical solution, the installation of the counterweight is facilitated by the cooperation of the partition plate and the side plate.

[0018] Optionally, the partition includes a base partition and an upper cover partition, the base partition abuts against the offset edge, and the outer edge of the base partition abuts against the inner wall of the mounting groove to support the ship base, and the side panel overlaps the base partition; the end of the upper cover partition abuts against the offset edge, and the outer edge of the upper cover partition abuts against the inner wall of the ship upper cover, and the upper cover partitions abut against the base partition one by one to support the ship upper cover.

[0019] By adopting the above technical solution, the base partition is used to abut against the inner wall of the ship's base to support the structure of the ship's base, and the upper cover partition is used to abut against the inner wall of the ship's upper cover to support the structure of the ship's upper cover. At the same time, the base partition and the upper cover partition abut against each other to support each other, making the ship's base and the ship's upper cover structure more stable.

[0020] Optionally, the counterweight includes a fixing frame, a battery, and a control panel. The bottom of the fixing frame is fixedly connected to the base partition. Two side panels are provided. The fixing frame is located between the two side panels, and the two sides of the fixing frame are respectively fixedly connected to the two side panels. The battery and the control panel are both fixedly connected to the fixing frame, and the control panel is electrically connected to the battery.

[0021] By adopting the above technical solution, the heavier components such as the battery and the control panel are installed deeper in the installation groove, so that the center of gravity of the entire unmanned boat is lowered. This not only makes the unmanned boat sail more stably during the mission, but also makes it less likely to capsize when encountering short-term severe external forces such as strong winds and waves.

[0022] Optionally, a camera is installed on the top of the ship cover, and the camera is electrically connected to the control panel.

[0023] By adopting the above technical solution, the camera is set up to monitor the environment around the hull.

[0024] Optionally, two lighting lamps are installed on the upper cover of the ship, the lighting lamps are electrically connected to the control panel, and the two lighting lamps are symmetrically arranged about the camera.

[0025] By adopting the above technical solution, two lighting lamps are symmetrically arranged about the camera, which helps to provide uniform lighting, making it easier for the camera to work at night or in low-light environments.

[0026] Optionally, two communication antennas are fixedly connected to the rear of the ship cover, and the communication antennas are electrically connected to the control panel.

[0027] By adopting the above technical solution, the setting of the communication antenna facilitates communication with the control panel, thereby making it easier for the operator to control the unmanned boat to perform operations.

[0028] Optionally, a signal light is also installed on the ship cover, and the signal light is located between the two communication antennas. The signal light displays multiple colors and is electrically connected to the control panel to display the communication status of the communication antennas.

[0029] By adopting the above technical solution, the communication status of the communication antenna is displayed using the color of the signal light, which helps to monitor the communication status in real time and ensure the reliability of communication.

[0030] Optionally, a plurality of drainage ridges are provided at the bottom of the ship base.

[0031] By adopting the above technical solution, the provision of the diversion ribs helps to reduce the resistance of water to the hull and improve the maneuverability of the hull.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] Through the coordination of the boat base, mounting slots, boat cover, mounting frame and counterweight, when a severe external force causes the unmanned boat to flip over, the position of the counterweight can automatically flip the unmanned boat back over, thus ensuring the unmanned boat's stable operation on the water;

[0041] The following is combined with Figure 1-3 This application is described in further detail.

[0042] The embodiments of the present application disclose a self-righting unmanned boat.

[0043] Reference Figure 1-3 The self-righting unmanned boat includes a boat base 1, a boat cover 2, and a mounting frame 3. A mounting groove 11 is provided in the boat base 1, and the cross-sectional area of ​​the boat base 1 decreases from the end of the opening of the mounting groove 11 to the end away from the opening of the mounting groove 11. The boat cover 2 is installed at the opening of the mounting groove 11, and the boat cover 2 protrudes upward. The mounting frame 3 is installed in the mounting groove 11, and a counterweight 4 is installed on the mounting frame 3. When the boat base 1 is underwater, the counterweight 4 is located below the waterline of the boat base 1, and when the boat cover 2 is underwater, the counterweight 4 is located above the waterline of the boat cover 2. The position of the counterweight 4 enables the unmanned boat to flip back in the event of capsizing, thereby ensuring the stable operation of the unmanned boat on the water.

[0044] In this embodiment, a propeller 12 is provided at the bottom of the boat base 1. In other embodiments, other types of power devices may also be used, such as sails, water pumps, etc. Two propellers 12 are provided, and the two propellers 12 are symmetrically arranged about the center line of the boat base 1, so that the propeller 12 can push the boat base 1 to move in the water.

[0045] The bottom of the base 1 is provided with a plurality of diversion ribs 13. In this embodiment, there are five diversion ribs 13. The five diversion ribs 13 are all arranged from the bow to the stern. The middle diversion rib 13 is located at the bottom of the base 1, and the other four diversion ribs 13 are arranged symmetrically about the middle diversion rib 13. The arrangement of the five diversion ribs 13 helps reduce the resistance of the water on the hull, thereby improving the maneuverability of the hull.

[0046] A plurality of staggered edges 14 are provided on the side wall of the boat base 1. The provision of the plurality of staggered edges 14 increases the rigid structure of the boat base 1, thereby increasing the structural strength and stability of the boat base 1. The side facing the opening of the mounting groove 11 is located inside the mounting groove 11, so that the cross-sectional area of ​​the boat base 1 decreases from one end of the opening of the mounting groove 11 to the end away from the opening of the mounting groove 11, that is, the boat base 1 is spindle-shaped. The spindle-shaped boat base 1 can not only reduce the friction between the hull and the water, but also the middle part of the spindle-shaped boat base 1 is the widest, thereby increasing the stability of the hull, resisting the influence of side winds and waves, and making the hull more stable during driving.

[0047] The mounting frame 3 includes several parallel partitions 31 and side panels 32 mounted on the partitions 31. The partitions 31 are supported on the offset edges 14. The counterweight 4 is mounted on the partitions 31 and the side panels 32. The cooperation between the partitions 31 and the side panels 32 facilitates the installation of the counterweight 4.

[0048] The bulkheads 31 in this embodiment include a base bulkhead 311 and a cover bulkhead 312. The base bulkhead 311 abuts against the offset ridges 14, and the outer edges of the base bulkheads 311 abut against the inner sidewalls of the mounting slots 11 to support the ship's base 1. The side panels 32 are provided with a plurality of overlapping grooves, which overlap the base bulkheads 311, thereby better controlling the distance between the base bulkheads 311.

[0049] The ends of the upper cover partitions 312 abut against the offset edges 14 , and the outer edges of the upper cover partitions 312 abut against the inner side walls of the ship cover 2 . The upper cover partitions 312 abut against the base partitions 311 one by one to support the ship cover 2 .

[0050] The base partition 311 is used to abut against the inner wall of the ship base 1 to support the structure of the ship base 1, and the upper cover partition 312 is used to abut against the inner wall of the ship upper cover 2 to support the structure of the ship upper cover 2. At the same time, the base partition 311 and the upper cover partition 312 abut against each other to support each other, making the structure of the ship base 1 and the ship upper cover 2 more stable.

[0051] The counterweight 4 includes a fixing frame 41, a battery 42, and a control panel 43. The bottom of the fixing frame 41 is fixedly connected to the base partition 311. Two side panels 32 are provided. The fixing frame 41 is located between the two side panels 32, and the two sides of the fixing frame 41 are fixedly connected to the two side panels 32 respectively. The fixing frame 41 is used to control the distance between the two side panels 32, so that the connection between the base partition 311 and the side panel 32 is more stable.

[0052] The battery 42 and control panel 43 are both fixedly connected to the mounting bracket 41, and the control panel 43 is electrically connected to the battery 42 and the propeller 12, respectively. Mounting the heavier components, the battery 42 and control panel 43, deeper in the mounting slot 11 shifts the center of gravity of the entire unmanned boat downward, making it more stable during missions and less likely to capsize in the event of a brief, intense external force, such as strong winds and waves.

[0053] In an optional embodiment, a camera 5 is installed on the top of the ship cover 2, and the camera 5 is electrically connected to the control panel 43. The camera 5 is used to monitor the environment around the hull.

[0054] Two lights 6 are installed on the upper cover 2, which are electrically connected to the control panel 43 and are symmetrically arranged about the camera 5. The two lights 6 are symmetrically arranged about the camera 5 to provide uniform lighting, which facilitates the operation of the camera 5 at night or in an environment with insufficient light.

[0055] The tail of the boat cover 2 is fixedly connected to two communication antennas 7, which are electrically connected to the control panel 43. The arrangement of the communication antennas 7 facilitates communication with the control panel 43, thereby facilitating the operator to control the unmanned boat to operate.

[0056] A signal light 8 is also mounted on the cover 2, located between the two communication antennas 7. It displays multiple colors and is electrically connected to the control panel 43 to indicate the communication status of the communication antennas 7. In this embodiment, the colors are red, green, and yellow. Red indicates a communication interruption, an error, or a problem requiring immediate attention; green indicates normal communication, a successful connection, and normal system operation; and yellow indicates limited communication, a weak signal, and the need for user action. Using the color of the signal light 8 to indicate the communication status of the communication antennas 7 facilitates real-time monitoring of the communication status and ensures communication reliability.

[0057] The implementation principle of a self-righting unmanned boat in an embodiment of the present application is as follows: when the boat base 1 is located underwater, the counterweight 4 composed of heavier devices such as the battery 42 and the control panel 43 on the mounting frame 3 is used to make the center of gravity of the unmanned boat below the waterline, thereby making the unmanned boat more stable when sailing, and the propeller 12 can push the boat base 1 to perform tasks smoothly in the water.

[0058] If a violent external force causes the boat cover 2 to be underwater, the position of the counterweight 4 on the mounting frame 3 makes the center of gravity of the unmanned boat located above the waterline, making the unmanned boat extremely unstable and easy to flip over again so that the boat base 1 is underwater. Therefore, when the unmanned boat is moving, even when a violent external force causes the unmanned boat to flip over, the position of the counterweight 4 can autonomously flip the unmanned boat back, thereby ensuring the stable operation of the unmanned boat on the water.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
