Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6The utility model provides a technical solution: a self-righting unmanned boat, including a hull 1, a first electric telescopic rod 2, an airbag 3, a first connecting plate 4, a first threaded rod 5, a first card slot 6, a first connecting block 7, a limiting slot 8, a first rotating shaft 9, a second rotating shaft 10, a second electric telescopic rod 11, a second connecting plate 12, a first transmission rod 13, a second transmission rod 14, a card block 15, a second card slot 16, a third connecting plate 17 and a counterweight 18, first electric telescopic rods 2 are arranged on both sides of the hull 1, and the airbag 3 is connected to the outside of the first electric telescopic rod 2, and the first connecting plate 4 is connected to the bottom of the hull 1, a first threaded rod 5 is arranged in the first connecting plate 4, and the first card slot 6 is arranged on the first connecting plate 4, and the first connecting plate 4 has a lower portion. A first connecting block 7 is connected to the side, a limiting groove 8 is arranged in the first connecting block 7, and a first rotating shaft 9 is connected in the limiting groove 8, and a second rotating shaft 10 is connected under the first rotating shaft 9, a second electric telescopic rod 11 is connected under the second rotating shaft 10, and a second connecting plate 12 is connected under the second electric telescopic rod 11, and a first transmission rod 13 is arranged at the front end inside the second connecting plate 12, a second transmission rod 14 is connected to the rear side of the first transmission rod 13, and a clamping block 15 is arranged on the second transmission rod 14, and a second clamping groove 16 is connected to the inner side of the clamping block 15, a third connecting plate 17 is connected in the second connecting plate 12, and second clamping grooves 16 are arranged on both sides of the third connecting plate 17, and a counterweight block 18 is connected to the bottom of the third connecting plate 17.

[0023] The first rotating shaft 9 is a left-right rotating structure, so that when the hull 1 turns over, the counterweight block 18 can be offset by the second electric telescopic rod 11, thereby changing the center of gravity position, so that the hull 1 can be automatically righted, and the second rotating shaft 10 is a front-to-back rotating structure, so that the second electric telescopic rod 11 and the second connecting plate 12 and the third connecting plate 17 at the bottom can be folded by rotating back and forth, which is convenient for storage, and the second rotating shaft 10 is a threaded rotating structure to avoid shaking back and forth due to external force, which affects righting and normal navigation.

[0024] The outer side of the second electric telescopic rod 11 is wrapped with a deflector to reduce the resistance to the navigation of the hull 1, and the deflector and the second electric telescopic rod 11 are telescopic structures of the same length, which is convenient for telescoping.

[0025] The first transmission rod 13 and the second transmission rod 14 form a transmission structure on the second connecting plate 12 through bevel gears, so that the second transmission rod 14 can rotate along with the rotation of the first transmission rod 13 , thereby changing the position of the clamping block 15 on the second transmission rod 14 .

[0026] The clamping block 15 is a semicircular structure on the second transmission rod 14, so that it can be disengaged from the second clamping slot 16 by rotating the second transmission rod 14, and the clamping block 15 forms a buckle structure with the second clamping slot 16 on the third connecting plate 17 through the rotation of the second transmission rod 14, so that the counterweight block 18 connected under the third connecting plate 17 is fixed by the buckle structure.

[0027] The third connecting plate 17 forms a buckle structure with the first clamping groove 6 and the first threaded rod 5 on the first connecting plate 4 through the rotation of the second rotating shaft 10, and a through-hole structure is provided on the third connecting plate 17, so that the third connecting plate 17 can be connected with the through-hole on the third connecting plate 17 through the first threaded rod 5 to fix the second electric telescopic rod 11 and the deflector on the rear side of the third connecting plate 17 to the bottom of the hull 1, so as to be folded.

[0028] Working principle: When using the self-righting unmanned boat, first, before using it, rotate the first threaded rod 5 on the first connecting plate 4 so that the first threaded rod 5 loosens the third connecting plate 17 stuck in the first slot 6, and then rotate the second rotating shaft 10 so that the connecting structure composed of the second electric telescopic rod 11 and the second connecting plate 12 rotates to the direction of the center of gravity, and then insert the counterweight block 18 into the slide groove inside the second connecting plate 12 through the third connecting plate 17, rotate the first transmission rod 13 outside the second connecting plate 12 so that the second transmission rod 14 inside rotates with the rotation of the first transmission rod 13, so that the block 15 on the second transmission rod 14 is driven to be stuck in the second slots 16 on both sides of the third connecting plate 17, and finally start the first electric telescopic rod 2 through the remote control device so that the airbags 3 on both sides of the hull 1 are deployed, and then the unmanned boat is put into the waters where detection is required to work;

[0029] When the hull 1 capsizes due to external reasons in the water area, the counterweight 18 will drive the second electric telescopic rod 11 to shift left and right in the limit groove 8 through the first rotating shaft 9 due to gravity, thereby changing the center of gravity position of the hull 1, and at the same time, the first electric telescopic rod 2 is contracted by the remote control device so that the airbag 3 is close to the hull, reducing the contact area between the hull 1 and the water surface, thereby accelerating the automatic righting of the hull 1, and at the same time, the second electric telescopic rod 11 is started by the remote control device, so that the counterweight 18 is shifted outward, so that the center of gravity shifts farther, thereby accelerating the righting speed, and when the hull 1 is righted, the first electric telescopic rod 2 is opened again by the remote control device to deploy the airbag 3, so that the hull 1 can sail stably. The contents not described in detail in the specification belong to the existing technology well known to professional and technical personnel in this field.
