Consequently to being provided with the unmanned ship of two pontoons among the prior art, need carry 3 to 4 people at least and compare, the work of carrying only needs two people can be accomplished to this embodiment, consequently uses more conveniently. And then solved the unmanned ship that exists among the prior art and need many people to carry at the removal in-process, consequently awkward technical problem.

Optionally, both side surfaces of the

first grip portion

gripping structures

23, 33 adapted to be gripped.

Specifically, fig. 2 is a schematic structural view of the pontoon of the portable unmanned ship shown in fig. 1, and fig. 3 is a schematic structural view of the pontoon shown in fig. 2, and referring to fig. 1 to 3, both side surfaces of the first grip portion 20a and the first grip portion 30a are gradually contracted inward in an upward direction. In one embodiment, the two side surfaces gradually converge in an upward direction to form an inverted V-shape. And, both side surfaces of the first grip portion are provided with

grip structures

Alternatively, the

grip structures

portions

21a, 31a, respectively.

Therefore, the propeller of the unmanned ship can be arranged in the concave part at the rear end of the buoy in the mode, and the hidden arrangement of the propeller is realized. Therefore, the propeller is hidden under the rear end structure of the buoy, so that all resistance is borne only by the front face of the buoy, and the additional resistance generated by the propeller in the process of sailing can be reduced. Therefore, the technical problem that the propulsion efficiency is influenced because the unmanned ship propeller in the prior art can be subjected to resistance in the operation process is solved.

buoys

2 and 3, namely, the bottoms of the bracket 22 and the bracket 32 extend beyond the lowest point of the bottoms of the

buoys

2 and 3, so that the rear end of the unmanned ship can be supported by the bracket 22 and the bracket 32 when the unmanned ship is on the shore, and the propeller is prevented from directly contacting the ground on the shore to cause blade abrasion.

Therefore, the unmanned ship adopting the technical scheme of the embodiment can ensure that the blades of the propeller cannot be collided by the reef when the unmanned ship is in water because the bracket is arranged around the propeller. In addition, the support is lower than the flotation pontoon minimum at vertical direction minimum, adopts this design can ensure that the paddle of propeller can not contact ground when unmanned ship is on the shore, consequently can increase life. Therefore, the technical problem that blades of the propeller of the unmanned ship are easy to impact or wear in the prior art is solved.
