[0002] ROVs are cable-attached devices used for underwater work, reconnaissance, and mining, and are designed with a disassembled appearance, which is completely different from the streamlined design of AUVs. Designing the main frame structure as a fluid section ensures that the device achieves lower resistance underwater and better maneuverability. Currently, the main frame structure of unmanned underwater vehicles is often a flat frame (made from square pipes, profiles, or circular pipes), and the overall structure tends to be square and flat, resulting in poor fluid performance and maneuverability.

[0003] Therefore, a planar configuration makes it difficult to control the submersible vehicle to perform useful work in a suitable attitude, especially when current velocities are relatively high and the cable is relatively long. Summary of the Invention [Problem to be solved by the invention]

[0016] The present invention will be described in more detail below with reference to specific examples.

[0017] As shown in Figures 1 to 3, an unmanned underwater vehicle (UAV) with a streamlined housing includes a housing 1, which has a head section at one end and a tail section at the other end, forming a streamlined shape from the head section to the tail section. The housing 1 is hollow and connected to a component section 2, which includes a rectangular frame structure 21. The frame structure 21 is installed inside the housing 1 and is used to support the housing 1 and to mount devices necessary for the UAV to operate. A frame extension beam 22 that passes through the housing 1 is connected to the frame structure 21. A thruster 3 is attached to one end of the frame extension beam 22, away from the frame structure 21, and drives the UAV to operate. A protective pipe 7 is installed outside the thruster 3, and the protective pipe 7 is installed around the thruster 3 to protect it and also protect the housing 1 from collisions.

[0018] Of these, a carrying mechanism 4 is fixed to component 2, and an opening is provided at the upper end of housing 1. The carrying mechanism 4 includes a carrying cross beam 41 provided in a corresponding opening in housing 1, and the carrying cross beam 41 is lifted by an external lifting device and is used for providing and retrieving the unmanned underwater vehicle.

[0019] Specifically, the component 2 and the handle mechanism 4 are both formed to weld and fix the hollow pipes at their ends, and the component 2 can play a role in supporting the housing 1 at its outer edge and four corners. The component 2 forms a mounting plane on its upper surface, which is formed by only four hollow pipes, on which a device can be mounted and fixed. Only four frame extension beams 22 are installed, and the four frame extension beams 22 are projecting and fixed to the four corners of the frame structure 21, respectively.

[0020] One end of each of the frame extension beams 22 is fixed to the component 2, and the remaining portion passes through the housing 1. The frame extension beam 22 has a first mounting port 5 at its center and a second mounting port 6 at its end away from the component 2.

[0022] Correspondingly, the protective piping 7 is installed in four groups, all of which are formed by welding hollow piping into a curve. In this embodiment, the handrail cross beam 41 is installed perpendicular to the longitudinal direction of the housing 1. The handrail mechanism 4 further includes a vertical handrail beam 42. The vertical handrail beams 42 are installed in pairs and are respectively fixed to both ends of the handrail cross beam 41, and one end of each vertical handrail beam 42 is fixed to one end of the handrail cross beam 41 and the other end is fixed to the component 2 along the vertical direction.

Each of the handle longitudinal beams 42 is installed in a rectangular configuration, with the top edge of the rectangular configuration connected to the handle cross beam 41 and both ends of the bottom edge fixed to the component 2.

[0024] In a preferred embodiment of the present invention, the hollow pipes forming the component 2 are connected together by welding. The first mounting opening 5 and the second mounting opening 6 are fixed to the frame extension beam 22 by welding, and the vertical handrail beam 42 is also fixed to the component 2 and the horizontal handrail beam 41 by welding.
