Fast disassembling and assembling semi-submersible three-body unmanned vehicle

Abstract

The invention relates to the technical field of unmanned vehicles, in particular to a fast disassembling and assembling semi-submersible three-body unmanned vehicle. The fast disassembling and assembling semi-submersible three-body unmanned vehicle include a main body and two auxiliary bodies, the main body is made from high-strength carbon fiber reinforced glass steel, the two auxiliary bodies adopt inflatable PVC buoys, and the auxiliary bodies and the main body are fixed through two high-strength carbon fiber connecting assemblies correspondingly; a plane groove type stabilization ballast tank is arranged in the center of the interior of the main body, a water inlet is formed in the bottom of the plane groove type stabilization ballast tank, a drainage port is formed in the side of theplane groove type stabilization ballast tank, and the water inlet and the drainage port are provided with electromagnetic valves; and oil-driven propeller is installed at the tail of the main body, and electric screw propellers are installed at the tails of the two auxiliary bodies. The unmanned vehicle adopts a three-body structure, has the better wave resistant stability, can effectively adjustthe draft and diving states, and provide the good working environment for carried acoustic instruments.

Description

technical field [0001] The invention relates to the technical field of unmanned boats, in particular to a quick disassembly and assembly semi-submersible three-body unmanned boat. Background technique [0002] As a sharp tool for ocean development and detection, unmanned boats are widely used in many aspects such as maritime military activities, marine scientific research, marine survey and stereoscopic observation, and monitoring of marine pollution environments. With the proposal of my country's marine power strategy, a series of marine equipment represented by unmanned intelligent ships and underwater robots has become a research hotspot in the field. [0003] Unmanned boats generally have three structural forms: single body, double body and three body. The traditional single unmanned boat construction technology is relatively mature and has a wide range of applications, but it has poor navigation stability and environmental adaptability.

AI Technical Summary

Problems solved by technology

The traditional single unmanned boat construction technology is relatively mature and has a wide range of applications, but it has poor navigation stability and environmental adaptability

Generally, the working sea conditions of small single-body unmanned boats are less than 4, and the load is limited, and the endurance is relatively poor.

Twin-hull unmanned boats generally have good maneuverability and navigation stability, and their loading capacity is also improved compared with single-hull unmanned boats, but the speed is generally slower

The three-body unmanned boat has better stability than the single-hull unmanned boat and the double-hull unmanned boat, and is very suitable for marine surveying and mapping tasks. However, compared with the above two structural forms, the traditional three-hull unmanned boat has more Large self-weight, inferior to single-hull and catamaran unmanned boats in terms of convenience

[0004] On the other hand, diesel-powered unmanned boats have the advantages of long battery life and fast propulsion speed, but the hull vibration caused by the engine when using this power mode is large. Large deadweight is not conducive to transportation, deployment and offshore precision scanning operations

The vibration of a single electric unmanned boat is small, which is conducive to carrying out precision scanning operations at sea, but the sailing speed of electric unmanned boats is generally slow and the endurance is poor

Generally, battery packs are connected in parallel to improve battery life, but this method greatly increases the weight of the hull and reduces the load capacity of the unmanned boat, which is not conducive to transportation, deployment and recovery.
