[0002] The utility model relates to the technical field of unmanned boats, in particular to a double-hull omnidirectional unmanned boat. Background Art

[0003] my country boasts numerous reservoirs and dams. Due to years of operation, structural aging, and geological disasters, these structures may be susceptible to problems such as concrete cracking and leakage, and metal equipment corrosion. To ensure project safety and long-term profitability, hazard detection and repair are key solutions. The complex water conditions near reservoirs and dams make manual exploration and inspection of underwater structures demanding comprehensive technical expertise. Furthermore, manual exploration poses a high safety risk and produces suboptimal inspection results.

[0004] Existing technology typically uses unmanned boats in conjunction with underwater robots (AUVs) for underwater exploration. The boat carries the AUV to a designated location, then lowers the robot into the water to inspect underwater structures. The boat's primary function is to carry the robot across the surface. However, existing boats lack flexibility and adaptability to complex waters. This limited mobility limits the AUV's exploration range, hindering operators' ability to fully assess the underwater structures. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be arbitrarily combined with each other.

[0026] See also Figures 1 to 3 A double-hull omnidirectional unmanned boat includes two hulls 10, a reserved cabin 20, and a control system. The two hulls 10 are symmetrically arranged on both sides of the reserved cabin 20 and connected to the reserved cabin 20. A propulsion device 30 is provided at the bottom of each hull 10. The driving direction of the two propulsion devices 30 is parallel to the length direction of the hull 10. The control system is electrically connected to the two propulsion devices 30 to control the two propulsion devices 30 to work independently, control the movement speed difference of the hulls 10 on both sides, and thereby change the driving direction of the unmanned boat.

[0027] The bow of the hull 10 is equipped with an acute tip to reduce the resistance faced by the hull 10 during navigation. The propulsion device 30 is installed at the bottom of the stern of the hull 10, transferring the power of the hull 10 to the stern to prevent the propulsion device 30 from being directly exposed to the water flow and reducing the driving efficiency of the propulsion device 30. The interior of the hull 10 is designed as a cavity to increase the buoyancy of the unmanned boat and improve the carrying capacity of the unmanned boat, making it easier for the unmanned boat to carry underwater robots.

[0028] The two hulls 10 are symmetrically arranged on both sides of the reserved cabin 20, and the two hulls 10 are connected through the reserved cabin 20, so that the unmanned boat has two connected bows; when the unmanned boat is sailing on the water, when encountering strong winds and waves, the two hulls 10 can effectively disperse the impact force of the waves, thereby making the unmanned boat remain stable on the water surface and increasing the navigation stability of the unmanned boat.

[0029] Both hulls 10 are equipped with power batteries 31 connected to corresponding propulsion devices 30. These batteries 31 are placed on either side of the unmanned boat to distribute its weight, reduce its swaying and rocking during travel, and maintain stability. Furthermore, the batteries 31 are positioned flush against the bottom of the hulls 10 to lower the center of gravity of the hulls 10 and the unmanned boat, preventing it from capsizing during maneuvering.

[0030] In this embodiment, the propulsion device 30 is a propeller propeller, and two power batteries 31 are connected to the two propulsion devices 30 to drive the operation of the two propulsion devices 30. The two propulsion devices 30 are electrically connected to a control system, which is used to control the rotation speed of the propulsion devices 30 to control the navigation speed of the unmanned vessel. The control system controls the independent operation of the two propulsion devices 30, and changes the movement speed of the two hulls 10 by changing the rotation speed of the two propeller propellers. When the rotation speeds of the two propulsion devices 30 are different, a speed difference is generated between the two hulls 10, which causes the unmanned vessel to deviate and achieve steering.

[0031] Furthermore, to increase the steering flexibility of the unmanned boat, a side thruster 40 is provided under the bow of the unmanned boat. The driving direction of the side thruster 40 is perpendicular to the driving direction of the propulsion device 30, and the side thruster 40 is electrically connected to the control system. When the unmanned boat needs to turn, the side thruster 40 is activated, supplemented by the side thrust of the unmanned boat, to accelerate the turning speed of the unmanned boat and improve the steering flexibility of the unmanned boat. Specifically, the side thruster 40 is also a propeller propeller. The side thruster drives the unmanned boat to the left or right in forward and reverse rotation, and then cooperates with the speed difference of the propulsion devices 30 on both sides to realize the steering of the unmanned boat, realizing the omnidirectional travel of the unmanned boat.

[0032] A reserved compartment 20 is set between the two hulls 10, and the reserved compartment 20 extends from the bow of the hull 10 to the middle of the hull 10, so that there is a gap between the sterns of the two hulls 10. The gap can be used to tow an underwater robot. The unmanned boat carries the underwater robot and moves it to a designated position and then lowers the underwater robot.

[0033] The reserved chamber 20 is hollow to increase the buoyancy of the unmanned boat. It can also be used to carry components, such as control systems, to prevent them from being installed externally and becoming damp, which could affect normal use. The reserved chamber 20 is equipped with a positioning device, which in this application is a GPS locator. The operator can use this positioning device to determine the position of the unmanned boat in the water. The reserved chamber 20 is also equipped with a camera 50. Specifically, the camera 50 is located at the bow of the unmanned boat, on the water surface, to capture the waterway environment during navigation. Human personnel can then conduct further analysis based on the image information to understand the water environment.

[0034] A bracket 61 is mounted above the reserved compartment 20, on which a radar 60 is mounted. Mounted above the unmanned vessel via bracket 61, the radar 60 is used to identify the environment and avoid obstacles. This improves the unmanned vessel's awareness of the surroundings while navigating the water, preventing collisions with obstacles such as reefs and other vessels, thereby enhancing its adaptability in complex waters. Positioning the radar 60 above the unmanned vessel reduces the impact of the vessel's structure on its detection. The radar 60 is electrically connected to a control system, which uses the environment detected by the radar 60 to perform obstacle avoidance and route planning, ensuring the safe operation of the unmanned vessel.

[0035] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; and such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
