DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0019] like Figure 1-4 An unmanned catamaran shown in the figure comprises a hull bottom plate 1 and a support base 2 located at the edges of both sides of the hull bottom plate 1, a front pontoon 3 and a rear pontoon 4 are arranged at the bottom of the support base 2, the front pontoon 3 and the rear pontoon 4 are located on the same straight line with a gap therebetween, a horizontally flipping auxiliary support member is installed in the gap between the front pontoon 3 and the rear pontoon 4, the auxiliary support member is arranged in two groups and is symmetrically arranged below the hull bottom plate 1, a flipping limiting member is installed at the rear end of the hull bottom plate 1, and when the auxiliary support member flips to below the hull bottom plate 1, the limiting member limits and fixes the auxiliary support member;

[0020] A steering motor 5 is installed at the front end of the hull bottom plate 1, the output shaft of the steering motor 5 extends downward and a steering rudder 6 is installed at the end of the output shaft;

[0021] A driving connecting rod 7 is installed at the rear end of the rear pontoon 4. The driving connecting rod 7 extends backward for a distance and then bends vertically downward. A propeller 8 is installed at the other end of the driving connecting rod 7.

[0022] When working, the hull bottom plate 1 provides buoyancy for the hull through the front buoy 3 and the rear buoy 4 on both sides, drives the steering rudder 6 through the steering motor 5 to provide the direction of the hull, and uses the propeller 8 to provide the power for the hull to move forward.

[0023] Furthermore, a flippable auxiliary support is installed at the bottom of the hull bottom plate 1. When the water surface conditions are complicated or the weather is extreme, the auxiliary support can be flipped from the bottom of the hull bottom plate 1 to the two sides of the hull bottom plate 1, so that the area and size of the entire hull bottom plate 1 in contact with the water surface are increased, buoyancy and stability are provided, and capsizing is avoided. The auxiliary support is flippable and foldable. After the water surface conditions return to normal, the auxiliary support can be retracted and folded to the bottom of the hull bottom plate 1, thereby increasing the travel speed and passability of the hull and improving practicality.

[0024] The auxiliary support member includes a lower connecting rod 9 fixed to the bottom of the supporting base 2, a first damping shaft 10 is installed at the bottom end of the lower connecting rod 9, the lower connecting rod 9 is connected to a rotating auxiliary rod 11 through the first damping shaft 10, an auxiliary buoy 12 is installed at the other end of the auxiliary rod 11, and the auxiliary buoy 12 is arranged parallel to the front buoy 3 and the rear buoy 4;

[0025] The auxiliary rod 11 is vertically arranged between the front pontoon 3 and the rear pontoon 4, and the auxiliary rod 11 is flipped between the first damping shaft 10 and the lower connecting rod 9;

[0026] An L-shaped rod 13 is installed on the lower connecting rod 9, and the L-shaped rod 13 extends to the outside of the supporting base 2. When the auxiliary rod 11 is flipped to the outside of the hull bottom plate 1 through the first damping shaft 10 and placed horizontally, the end of the L-shaped rod 13 is attached to the outer wall of the auxiliary rod 11;

[0027] On the basis of the above, the auxiliary buoy 12 is flipped at the lower connecting rod 9 at the bottom of the supporting base 2 through the auxiliary rod 11 and the first damping shaft 10. When idle, the auxiliary buoy 12 is flipped to the bottom of the hull bottom plate 1 through the auxiliary rod 11 and the first damping shaft 10. When needed, the auxiliary buoy 12 is flipped to both sides of the hull bottom plate 1 through the auxiliary rod 11 and the first damping shaft 10.

[0028] A first magnet 14 is installed on the hull bottom plate 1, and a second magnet 15 is installed on the outer wall of the auxiliary rod 11. When the auxiliary rod 11 is turned over to the bottom of the hull bottom plate 1 through the first damping shaft 10, the first magnet 14 and the second magnet 15 are attracted to each other.

[0029] Furthermore, when the auxiliary buoy 12 flips over to the bottom of the hull bottom plate 1, the first magnet 14 on the auxiliary rod 11 is attracted to the second magnet 15 at the bottom of the hull bottom plate 1, thereby fixing the auxiliary rod 11 and the auxiliary buoy 12 under the hull bottom plate 1 to avoid unnecessary shaking of the auxiliary buoy 12.

[0030] When the auxiliary buoy 12 moves to both sides of the hull bottom plate 1 and is placed horizontally, the auxiliary rod 11 will abut against the end of the L-shaped rod 13 on the lower connecting rod 9, limiting the position of the auxiliary buoy 12 and the auxiliary rod 11, so that the auxiliary buoy 12 can provide effective buoyancy and thus improve the stability of the hull. In addition, the auxiliary buoy 12 and the auxiliary rod 11 can freely adjust a certain angle downward during the ups and downs of the water surface, further improving the stability of the hull when the water surface conditions are complicated.

[0031] The limiting member includes a support rod 16 installed at the rear end of the hull bottom plate 1, the support rod 16 is vertically arranged on the surface of the hull bottom plate 1, a second damping shaft 17 is installed at the top end of the support rod 16, a bent hoop 18 is connected between the second damping shafts 17 of the two support rods 16, and two slots 19 for the hoop 18 to pass through are opened on the surface of the hull bottom plate 1, and the hoop 18 is flipped at the top end of the support rod 16 through the second damping shaft 17 and moved to the inside of the slot 19.

[0032] Further, such as Figure 2-3As shown, when the auxiliary buoy 12 moves to under the hull bottom plate 1, the hoop 18 can be flipped by the second damping shaft 17 to move the hoop 18 into the slot 19. The hoop 18 clamps the ends of the buoys in the auxiliary support members on both sides, provides a limit for the auxiliary support members when they are placed on the hull bottom plate 1, and cooperates with the damping of the second damping shaft itself and the adsorption between the magnets to avoid unnecessary shaking of the auxiliary support members during idleness.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
