[0027] Embodiment 1

[0028] See also Figures 1 to 4 , the utility model provides a technical solution: an unmanned boat with a protective structure, comprising an upper hull 1 and a lower hull 2, wherein the lower hull 2 ​​is fixedly connected to the bottom end of the upper hull 1;

[0030] The recoil propeller 8 is installed in a groove at the bottom of the metal shell 5 of the lower hull 2, and plays a role in balancing the water flow and stabilizing the hull in the lower hull 2;

[0031] The unmanned boat uses the underwater balance paddle 7 to move the center of gravity downward as a whole, reducing the degree of shaking of the hull in windy and wave conditions. In the case of strong winds and waves, the unmanned boat can drive the recoil propeller 8 to draw the water upward, generating downward pressure on the hull to maintain the stability of the hull.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, the upper hull 1 includes a plastic shell 3 and a signal antenna 4, the signal antenna 4 is fixedly connected to the rear side of the top of the plastic shell 3, and the signal antenna 4 is provided with two groups and symmetrically arranged at the rear side of the top of the plastic shell 3;

[0034] The lower hull 2 ​​includes a metal shell 5, a power propeller 6, an underwater balancing propeller 7 and a recoil propeller 8. The power propeller 6 is fixed to the rear side of the metal shell 5, and the underwater balancing propeller 7 is fixedly connected to the bottom of the metal shell 5. The bottom of the metal shell 5 is provided with grooves, and the grooves are provided in four groups and symmetrically arranged at the four corners of the bottom of the metal shell 5. The recoil propeller 8 is installed in each group of grooves;

[0035] When in use, the power propeller 6 drives the hull forward, and when the hull moves forward, it drives the underwater balance paddle 7 to break the water and move. When encountering large fluctuations on the water surface, the four sets of recoil propellers 8 can balance the hull.

[0036] Embodiment 3

[0037] On the basis of the first embodiment, the underwater balancing paddle 7 includes a fixing frame 9, a metal shaft 10 and a three-section paddle blade 11, the outer wall of the metal shaft 10 is fixedly connected to the fixing frame 9, the outer wall of the metal shaft 10 is rotatably connected to the three-section paddle blade 11 through a rotating shaft, and the three-section paddle blade 11 is provided in a plurality of groups and is evenly arranged on the outer wall of the metal shaft 10;

[0038] The metal shaft 10 cooperates with the metal shell 5 to lower the center of gravity. A motor is built into each turning point of the three-section blade 11. During normal driving, the motor can drive the blade to swing in the water as the hull moves forward, thereby assisting the boat to move forward. When the water surface fluctuates, the hull with the center of gravity lowered will not easily tilt or capsize.

[0039] The recoil propeller 8 includes a propeller body 12, an adjusting hydraulic rod 13 and a spherical shaft head 14. The top of the propeller body 12 is fixedly connected with the spherical shaft head 14.

[0042] When encountering bad weather, the hull will experience large ups and downs. At this time, the blades on the surface of the propeller body 12 can be driven to rotate. The propeller body 12 attracts the water upward, driving the hull to generate downward pressure. The four groups of propeller bodies 12 are fixed around the hull to provide downward pressure to maintain stability, and the output direction of the propeller body 12 can also be adjusted according to the actual situation during driving. During adjustment, the output end of the adjusting hydraulic rod 13 pushes the top of the propeller body 12 outward. At this time, the spherical shaft head 14 slides in the spherical slide groove to adjust the direction of the propeller body 12. Two groups of adjusting hydraulic rods 13, one horizontal and one vertical, can respectively drive the propeller body 12 to move in two directions.
