[0065] The following is for reference. Figures 1-5 A description of an unmanned underwater vehicle 10 according to an embodiment of the present invention includes: a frame 100; a mounting component 200, one end of which is fixedly connected to one end of the frame 100; a sealing component 300, disposed at the other end of the frame 100, and having a controller (not shown in the figure) inside the sealing component 300 for controlling the movement of the unmanned underwater vehicle 10; a sampling component 400, disposed at the end of the sealing component 300 away from the frame 100, and electrically connected to the controller; and a sonar sensor 500, disposed on one side of the sealing component 300, and electrically connected to the controller.

[0066] Specifically, the frame 100 can be constructed as a frame structure assembled from multiple irregular rectangular plates. The frame 100 can be constructed from lightweight, high-strength, and corrosion-resistant materials, such as titanium alloy, high-strength aluminum alloy, or composite materials, thereby significantly extending the service life of the unmanned underwater vehicle 10 while simultaneously reducing its weight. The frame 100 provides stable support and protection for the internal components of the unmanned underwater vehicle 10 to withstand underwater pressure and external impacts, thus ensuring the normal operation of the unmanned underwater vehicle 10 in the underwater environment.

[0067] One end of the mounting component 200 can be fixedly connected to one end of the frame 100 via a threaded connection. The mounting component 200 can be slidably connected to external devices, such as rails or cables on a transport vehicle, facilitating the rapid installation, disassembly, and transportation of the unmanned underwater vehicle 10. This allows the unmanned underwater vehicle 10 to be transported to the corresponding work location via the mounting component 200, thereby significantly improving the transportation efficiency of the unmanned underwater vehicle 10 and enhancing its versatility and practicality.

[0068] The sealing component 300 can be fixedly disposed at the other end of the frame 100 along the height direction of the frame 100, wherein the height direction of the frame 100 can be... Figure 1 The direction indicated by X in the middle. The sealing assembly 300 can be constructed of high-strength metal materials. High-strength metal materials have high yield strength, tensile strength, and fatigue strength, which can maintain the integrity and stability of the sealing assembly 300 under heavy loads, thereby significantly improving the safety and stability of the sealing assembly 300. The sealing assembly 300 can provide a waterproof sealing environment for internal parts, protecting the delicate electronic equipment inside the sealing assembly 300 from water corrosion, thereby significantly extending the service life of the unmanned submersible device 10.

[0069] The controller can be fixedly installed inside the sealing assembly 300 via a threaded connection. This configuration provides a stable and safe operating environment for the controller, ensuring its safety. The controller is responsible for controlling the movement of the unmanned underwater vehicle 10, including forward, backward, ascent, descent, and turning movements. It achieves precise control of the underwater vehicle by sending control commands to the first thruster 1000 and the second thruster 1100 in the following embodiments, thereby significantly improving the working efficiency of the unmanned underwater vehicle 10.

[0070] The sampling component 400 can be positioned along the height of the frame 100 at the bottom of the sealing component 300. The sampling component 400 can be electrically connected to the controller via a wired connection. With this configuration, the controller can control the sampling component 400 to perform underwater environmental sample collection, such as: grabbing objects, collecting water samples, collecting sediments, capturing organisms, etc. By configuring the controller and the sampling component 400, the unmanned submersible device 10 can autonomously sample water at different depths, thereby improving the practicality of the unmanned submersible device 10.

[0071] The sonar sensor 500 can be fixedly installed to the sealing assembly 300 via a threaded connection. Along the width direction of the frame 100, the sonar sensor 500 can be fixedly installed on one side of the sealing assembly 300. The width direction of the frame 100 can be... Figure 1The direction indicated by Y in the diagram. The sonar sensor 500 can be electrically connected to the controller via a waterproof cable. With this configuration, the controller can use the sonar sensor 500 for underwater navigation and imaging. The sonar sensor 500 can calculate the position, distance, depth, and velocity of a target by emitting sound waves and receiving the echoes reflected from objects or boundaries it encounters. It also generates an image of the underwater environment and feeds it back to the controller, thus providing the controller with crucial environmental perception information. The controller can use the real-time environmental information to adjust the movement of the unmanned underwater vehicle 10 to achieve navigation, obstacle avoidance, and target object search, thereby enabling the unmanned underwater vehicle 10 to complete its work more safely and efficiently.

[0072] According to the embodiments of the present invention, the unmanned underwater vehicle 10 provides stable support and protection for its internal components by setting a frame 100 to resist underwater pressure and external impacts, thereby ensuring the normal operation of the unmanned underwater vehicle 10 in the underwater environment. By setting a mounting component 200, the unmanned underwater vehicle 10 can be transported to the corresponding work location, thereby significantly improving the transportation efficiency of the unmanned underwater vehicle 10 and thus improving its versatility and practicality. By setting a sealing component 300, a waterproof sealing environment can be provided for the internal parts, protecting the internal precision electronic equipment from water corrosion, thereby greatly extending the service life of the unmanned underwater vehicle 10. By setting a sampling component 400, underwater environmental samples can be collected, and water quality samples can be taken at different depths, thereby improving the practicality of the unmanned underwater vehicle 10. By setting a sonar sensor 500, key environmental perception information can be provided to the controller, which can adjust the movement position of the unmanned underwater vehicle 10 based on real-time environmental information to achieve navigation, obstacle avoidance, and target object search, thereby enabling the unmanned underwater vehicle 10 to complete its work more safely and efficiently.

[0073] Please continue reading Figures 1-3 As shown, the unmanned underwater vehicle 10 also includes: a connecting plate 600, the two opposite ends of the connecting plate 600 being fixedly connected to the other end of the frame 100; and a side plate 700, one end of the side plate 700 being fixedly connected to one side of the connecting plate 600, and the inner sidewall of the bottom of the side plate 700 being fixedly connected to the sampling component 400.

[0074] Specifically, the connecting plate 600 can be constructed as a hollow rectangular structure. The two ends of the connecting plate 600 can be fixedly connected to the other end of the frame 100 by welding or threaded connection. With this configuration, the connecting plate 600 and the frame 100 can form a hollow rectangular compartment. When the unmanned submersible device 10 enters the underwater working environment, the water can flow quickly through the rectangular compartment, thereby ensuring the stability of the unmanned submersible device 10 when it quickly dives.

[0075] The side plate 700 can be constructed as an irregular plate-shaped structure with multiple through holes (not shown in the figure). There can be two side plates 700, which are respectively set on both sides of the frame 100 along the length direction of the frame 100. One end of the side plate 700 can be fixedly connected to one side of the connecting plate 600 by welding or threaded connection. The inner side wall of the side plate 700 can be fixedly connected to the sampling component 400 by threaded connection. This makes it easier for the side plate 700 to provide stable support for the sampling component 400, thereby improving the stability and safety of the sampling component 400.

[0076] Please continue reading Figures 1-3 As shown, according to one embodiment of the present invention, the unmanned underwater vehicle 10 further includes: a support plate 800, which is respectively disposed on opposite sides of the sealing assembly 300 along the width direction of the frame 100, and one end of the support plate 800 is fixedly connected to the side plate 700; a ballast tank 900, one side of the ballast tank 900 is connected to one side of the support plate 800; a first thruster 1000, one end of the first thruster 1000 is connected to the other side of the support plate 800 away from the frame 100, and the first thruster 1000 is used to adjust the horizontal movement of the unmanned underwater vehicle 10; and a second thruster 1100, which is disposed on opposite sides of the sealing assembly 300, and the second thruster 1100 is used to adjust the vertical movement of the unmanned underwater vehicle 10.

[0077] Specifically, the support plate 800 can be constructed as a rectangular plate structure, and there can be four support plates 800, which are evenly installed on opposite sides of the sealing assembly 300. One side of the support plate 800 can be fixedly connected to the inner wall of the side plate 700 by means of threaded connection or welding. The support plate 800 can be used to support and install components such as the first thruster 1000 and the second thruster 1100, thereby providing a stable installation foundation for the first thruster 1000 and the second thruster 1100.

[0078] It should be noted that the unmanned submersible device 10 also includes a ballast chamber 900. The ballast chamber 900 can be constructed as a hollow rectangular structure, a hollow circular structure, or an irregular hollow structure. This embodiment of the invention does not specifically limit its construction. The bottom of the ballast chamber 900 can be fixedly connected to the side of the support plate 800 opposite to the first thruster 1000 via a threaded connection. This facilitates stable support of the ballast chamber 900 by the support plate 800. It should be noted that the bottom shape of the ballast chamber 900 can be consistent with the cross-sectional shape of the support plate 800, thereby significantly improving the stability of the ballast chamber 900 during installation with the support plate 800.

[0079] The ballast tank 900 can be electrically connected to the controller to enable the unmanned underwater vehicle 10 to descend, ascend, and hover. By injecting seawater into the ballast tank 900, the weight of the unmanned underwater vehicle 10 can be increased, thereby increasing its negative buoyancy and enabling it to descend. By discharging the seawater from the ballast tank 900, the weight of the unmanned underwater vehicle 10 can be reduced, giving it positive buoyancy and enabling it to ascend. By precisely controlling the water volume in the ballast tank 900, the unmanned underwater vehicle 10 can achieve neutral buoyancy, allowing it to hover stably at any depth and reducing its propulsion energy consumption.

[0080] Furthermore, the number of first thrusters 1000 can match the number of support plates 800. One end of each first thruster 1000 can be fixedly connected to the side of the support plate 800 away from the frame 100 by bolts. This facilitates the support plate 800 providing support for the first thrusters 1000, thereby ensuring the stability and safety of the first thrusters 1000. The first thrusters 1000 can be electrically connected to the controller via wired connection. The controller can control the first thrusters 1000 to adjust the horizontal movement of the unmanned underwater vehicle 10. The first thrusters 1000 generate thrust through rotation, enabling the underwater vehicle to move forward, backward, or turn horizontally.

[0081] The number of second thrusters 1100 can be two. The second thrusters 1100 can be fixedly installed on opposite sides of the sealing assembly 300 by means of threaded connection. The second thrusters 1100 can be electrically connected to the controller by means of wired connection. The controller can control the second thrusters 1100 to adjust the vertical movement of the unmanned diving device 10, so that the diving device can rise or fall to adapt to different water depth mission requirements.

[0082] Through the coordinated operation of the first thruster 1000 and the second thruster 1100, the unmanned underwater vehicle 10 can move horizontally and vertically underwater and flexibly traverse underwater space. The controller precisely controls the speed and direction of the thrusters according to the mission requirements and the feedback information from the sonar sensor 500, thereby achieving precise control of the underwater vehicle so that it can reach the designated work area to complete sampling tasks at different water depths.

[0084] Specifically, the mounting plate 210 can be constructed as an irregular plate structure. The construction material of the mounting plate 210 can be a metal material, such as stainless steel. Stainless steel has a low carbon content, good corrosion resistance and high temperature resistance, and can resist the erosion of seawater and chemicals. It can maintain stable performance in complex underwater environments and has high mechanical strength, which can withstand the weight of the unmanned underwater vehicle 10 and external impacts, thereby greatly improving the stability and safety of the unmanned underwater vehicle 10 during transportation.

[0085] One end of the mounting plate 210 can be fixedly connected to the frame 100 by bolts to ensure that the connection between the mounting plate 210 and the frame 100 is firm and reliable, and can withstand the weight of the unmanned underwater vehicle 10 and various forces generated when the unmanned underwater vehicle 10 moves underwater.

[0086] One side of the pulley 220 can be movably connected to the other end of the mounting plate 210 via a bearing, which facilitates the smooth rotation of the pulley 220. The pulley 220 can be used to slide and connect with external devices, such as with rails or cables on a transport vehicle, to facilitate the rapid installation, disassembly, and transport of the unmanned underwater vehicle 10.

[0087] By setting up the mounting component 200, it is easy to connect and slide the unmanned underwater vehicle 10 with the external transportation device, which facilitates the transportation and deployment of the unmanned underwater vehicle 10 and improves the ease of use and mission adaptability of the unmanned underwater vehicle 10.

[0090] The second sealed chamber 320 can be located at the bottom of the first sealed chamber 310. The bottom of the second sealed chamber 320 can be fixedly connected to the sampling component 400 via a bracket (not shown in the figure) to ensure the stability of the second sealed chamber 320. The controller can be fixedly installed inside the second sealed chamber 320 via a threaded connection. In this configuration, the second sealed chamber 320 can provide a stable and sealed operating environment for the controller, ensuring the safety of the unmanned submersible device 10 during underwater operations.

[0091] Multiple connection ports 330 can be provided at one end of both the first sealed chamber 310 and the second sealed chamber 320, so that the components inside the first sealed chamber 310 and the second sealed chamber 320 can be connected to other components of the unmanned submersible device 10 via waterproof cables.

The compass and pressure sensor can be electrically connected to the controller by wired connection. With this configuration, the compass can provide directional information to the unmanned underwater vehicle 10, and the pressure sensor can be used to measure parameters such as water depth. The compass and pressure sensor can work together to provide the controller with comprehensive environmental information to ensure that the unmanned underwater vehicle 10 operates safely and efficiently underwater.
