In addition, the rear ends of the

buoys

2 and 3 are provided with second holding portions suitable for holding, so that the stern portion of the portable unmanned ship can be lifted by only one person. In a preferred embodiment, the

pontoons

2, 3 are typically constructed of a lightweight, strong material, such as carbon fiber.

Therefore, the first holding part and the second holding part are respectively arranged at the front end and the rear end of the two buoys of the portable unmanned ship, so that the portable unmanned ship can be carried or moved only by respectively holding the first holding part and the second holding part by two persons. 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 are gradually contracted inward in an upward direction, and both side surfaces of the first grip portion are provided with grip structures adapted to be gripped.

Alternatively, the grip structure is formed by a through hole penetrating both side surfaces of the first grip portion.

propeller

4, 5, and the

propeller

4, 5 is arranged outside the

first compartment

201, 301. In case of damage to the thruster circuit, the hatch of the

first compartment

201, 301 may be opened for repair or replacement of the circuit. The chamber (first chamber) in which the circuit is installed is provided at the rear end of the pontoon and is close to the propeller, thereby facilitating maintenance and replacement of the propeller. The

propellers

4, 5, such as, but not limited to, a battery, and an oil, gas, etc. energy source for powering the propellers in a preferred embodiment. Because the volume and the weight of the energy device are larger, the unmanned ship can float in water more stably by arranging the second cabin for accommodating the energy device in the middle of the buoy.

Therefore, by the mode, a plurality of cabins can be arranged on the buoy of the unmanned ship, and the space of the buoy can be well utilized. In addition, the maintenance and the replacement of the propeller are convenient, and the stability of the ship body can be ensured. Therefore, the technical problem that the pontoon of the unmanned ship in the prior art cannot reasonably utilize the space and keep the ship body stable is solved.

first grip portions

20a and 30a of the pontoon 2 and the pontoon 3 are respectively provided at the same positions of the front ends of the pontoon 3 and the pontoon 2, respectively, so that the bow portion of the portable unmanned ship can be lifted by only one person by holding the

first grip portions

20a and 30a of the pontoon 3 and the pontoon 2 with both hands of one person. In addition, the rear ends of the

buoys

2 and 3 are provided with second holding

portions

20b and 30b suitable for holding, that is, the rear end of the buoy 2 is provided with the second holding portion 20b, and the rear end of the buoy 3 is provided with the second holding portion 30b, so that only one person is needed to lift the stern part of the portable unmanned ship. In a preferred embodiment, the

pontoons

Referring to fig. 8, 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

23, 33 suitable for gripping, i.e. the first grip portion 20a is provided with the grip structure 23, and the first grip portion 30a is provided with the grip structure 33. Since the grip structure is provided on the first grip portion and both side surfaces of the first grip portion 30a are gradually contracted inward in an upward direction, the cross section of the grip structure is further small for easy grip.

Alternatively, the

grip structures

23, 33 are formed by through

holes

24, 34 penetrating both side surfaces of the

first grip portion

20a, 30 a. Specifically, referring to fig. 7 and 8, the grip structure 23 may be formed of a through hole 24 penetrating both side surfaces of the first grip portion 20a, and the grip structure 33 may be formed of a through hole 34 penetrating both side surfaces of the first grip portion 30 a. I.e., the gripping structure 23 corresponds to the through hole 24 and the gripping structure 33 corresponds to the through hole 34, further, the shape of the through

holes

24, 34 is, for example, but not limited to, circular or rectangular, etc. Through setting up the through-hole that runs through first portion of gripping as the structure of gripping, can be more be convenient for grip, and then more conveniently carry this portable unmanned ship.

Alternatively, as shown in fig. 9, the bottom of the rear end of the pontoon 2 is recessed upward in the rearward direction to form a recess 21a capable of accommodating the propeller 4, and similarly, the bottom of the rear end of the pontoon 3 is recessed upward in the rearward direction to form a recess 31a capable of accommodating the propeller 5, that is, the bottom of the rear end of the pontoon is closer to the upper portion in the vertical direction, so that the rear end of the pontoon can be recessed. And the

pushers

4, 5 are mounted to the recessed

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.

Optionally, the

pontoons

2, 3 are streamlined in shape. The design of the streamline buoy can greatly reduce underwater resistance, so that the unmanned ship can improve higher propelling efficiency.

In summary, the unmanned ship according to the technical scheme of the embodiment is provided with the support around the propeller, so that the blades of the propeller cannot be collided by the reef when the unmanned ship is in water. 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.
