Description

Technical Field

[0001] The present invention relates to an unmanned boat for dam inspection and detection, and is particularly applicable to inspection of hidden dangers and dangerous situations in dams, belonging to the technical field of unmanned boats. Background Art

[0002] Regular inspections and frequent repairs are key priorities in traditional dam protection. However, these methods rely heavily on manpower, especially during flood season, requiring 24 / 7 inspections to promptly detect and address potential hazards. Even so, traditional dam protection still faces numerous challenges, such as limited manual measurement range, dangerous underwater operations, and low emergency response efficiency. Therefore, the use of unmanned boats and other equipment to replace manual inspections of dams, reservoirs, and other structures is becoming a mainstream trend.

[0003] For example, Chinese patent publication number CN215155496U discloses an unmanned patrol boat for reservoirs. Stabilizing plates are installed on both sides of the boat's body, with several buoys mounted on the bottom of each plate. A waterproof box is mounted on the upper end of the boat's body, housing a battery, an intelligent controller, a GPS locator, a wireless communication module, and a data storage device. A support rod is mounted on the upper end of the waterproof box, housing a cloud-based camera. Several radars are mounted on the front end of the boat's body. Photovoltaic panels are installed at an angle on both sides of the support rods. The panels are connected to the battery's charging terminal via a converter, and the battery is connected to the power terminal of the intelligent controller via wires. This design enables rapid patrol and inspection, facilitates quick operation, is highly stable, and is easy to use. Its simple structure allows for rapid warning, improves efficiency, and is easy to operate.

[0004] However, the unmanned patrol boat is powered solely by batteries, and its endurance is extremely limited and needs further improvement. Furthermore, the unmanned patrol boat has a fixed monitoring function. During flood season, when levee inspections require different monitoring functions, unmanned patrol boats with other monitoring functions are needed to meet these needs, resulting in a waste of resources. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an unmanned boat for dam inspection and testing.

[0006] The present invention is achieved through the following technical solutions:

[0007] An unmanned boat for dam inspection and testing comprises a hull and an electronics compartment, a moon pool, a battery compartment and a fuel power supply assembly arranged on the hull. The electronics compartment is arranged at the front of the hull, the moon pool and the fuel power supply assembly are arranged in the middle of the hull, and the battery compartment is arranged at the rear of the hull.

[0008] The ship body is an aluminum alloy double ship body; the bottom of the ship body is a buoyancy cabin, and the buoyancy cabin comprises a middle independent buoyancy cabin and left and right independent buoyancy cylinders arranged at the bottom of the middle independent buoyancy cabin.

[0009] The left and right sides of the ship body are each provided with a line cabin; four inspection holes are respectively arranged on the inner walls of the left and right sides of the ship body; a front lifting handle is arranged at the front end of the ship body, and three side lifting handles are respectively arranged at the left and right sides of the ship body; a plurality of front lifting lugs are arranged at the front end of the ship body, and a plurality of rear lifting lugs are arranged at the rear end of the ship body.

[0010] The battery cabin is internally provided with a storage battery and an inverter, and the inverter is electrically connected with the storage battery.

[0011] The electronic cabin is internally provided with a controller, a video transmission module and a data transmission module, the controller is electrically connected with the storage battery, and the video transmission module and the data transmission module are both electrically connected with the controller.

[0012] The ship body is provided with a front antenna rack and a rear antenna rack.

[0013] The front antenna rack is provided with a millimeter wave radar, a red mast top lamp, a front RTK, a holder camera and an auxiliary illuminating lamp which are electrically connected with the controller, and is provided with a video transmission antenna which is electrically connected with the video transmission module, and is provided with a data transmission antenna which is electrically connected with the data transmission module.

[0014] The rear antenna rack is provided with a rear RTK and a white tail lamp which are electrically connected with the controller.

[0015] A plurality of red and green navigation lights which are electrically connected with the controller are arranged at the edges of the top of the ship body; a plurality of distance measuring radars which are electrically connected with the controller are respectively arranged at the front end of the top of the ship body and at the edges of the left and right sides of the top of the ship body; a hanging machine plate is arranged at the rear end of the ship body, and a ship propeller is arranged on the hanging machine plate and electrically connected with the controller and the inverter.

[0016] The fuel power supply assembly comprises a fuel cabin and a fuel generator, the fuel generator is electrically connected with the controller and the ship propeller, is connected with the fuel cabin through an oil pipe and is electrically connected with the storage battery through a rectifier;

[0017] The fuel cabin comprises an aluminum alloy outer cabin body and an aluminum alloy inner cabin body arranged on the inner side of the aluminum alloy outer cabin body, foam blocks or rubber blocks are filled in the gap between the aluminum alloy outer cabin body and the aluminum alloy inner cabin body, and a plurality of aluminum alloy longitudinal partitions and aluminum alloy transverse partitions which are arranged in a longitudinal and transverse manner are arranged in the aluminum alloy inner cabin body.

[0018] The beneficial effects of the present application are as follows:

[0019] 1. The battery compartment and fuel power supply components serve as the unmanned boat's power source, further improving its endurance. A moon pool is installed on the hull to reserve space for the installation of relevant instruments for the expansion of the unmanned boat's monitoring functions. During flood season, when different monitoring purposes are required for levee inspections, instruments with relevant monitoring functions can be positioned and clamped into the moon pool according to inspection requirements. This allows the unmanned boat to adapt to inspections requiring different monitoring functions, eliminating the need to customize the unmanned boat for different monitoring functions. This allows a single unmanned boat to meet various inspection needs, avoiding resource waste and reducing procurement costs.

[0020] 2. The electronic cabin is located at the front of the hull, the moon pool and fuel power supply components are located in the middle of the hull, and the battery cabin is located at the stern of the hull, so that the weight of the entire hull is evenly distributed. On the one hand, it improves its stability when moving on the water surface. On the other hand, it provides a guarantee for the stable debugging and use of patrol equipment, so that the patrol equipment does not need to consider the changes in the draft depth of the hull during the debugging and use process, thereby improving the use efficiency of the patrol equipment and making the unmanned boat more practical.

[0021] 3. The buoyancy provided by the left and right independent pontoons at the bottom of the central independent pontoon is sufficient to support the entire empty weight of the hull. Once the equipment is loaded onto the hull, the central independent pontoon begins to provide buoyancy, with a maximum buoyancy of one ton. Furthermore, the buoyancy compartment design, consisting of a "central independent pontoon + left independent pontoon + right independent pontoon," allows the hull to support the large-capacity battery load and the large fuel tank, significantly extending the unmanned boat's endurance with a full fuel tank and charge.

[0022] 4. Due to the large size of the fuel tank and the low viscosity of the fuel it contains, the fuel tank is designed as an aluminum alloy outer tank + aluminum alloy inner tank, and the gap between the two is filled with flexible materials (foam blocks or rubber blocks). This can reduce the impact of waves on the fuel tank during the operation of the unmanned boat. At the same time, the internal space of the fuel tank is divided into multiple small tanks by aluminum alloy longitudinal and aluminum alloy transverse partitions, further reducing the fluctuation and impact of the fuel inside the fuel tank, and also reducing the generation of static electricity. Finally, the fuel tank is made of aluminum alloy, which is light in weight, strong in strength, and can effectively conduct away the static electricity generated during the use of the fuel tank.
