Mixed submarine navigation device

Abstract

The mixed submarine navigation craft has the advantages of both underwater glider and underwater navigation craft combined together. It consists of a head compartment, a buoyancy driving and controlling compartment, a pose controlling compartment, a wing compartment, a battery compartment and a tail compartment connected successively. It has one buoyancy driving system comprising an outer casing, an inner casing and a hydraulic system; one pose regulating system comprising a pitch regulating system and a roll regulating system; two wings with two rotation freedoms each and capable of being withdrawn for fast propulsion; and one navigation and control system for craft pose measurement, navigation, buoyancy control, etc. The present invention is one modular designed structure and may embark proper measurement sensors and task modules for various water operations.

Description

technical field [0001] The invention relates to an underwater vehicle capable of carrying a measuring sensor. technical background [0002] In order to protect the marine environment and efficiently utilize marine resources, marine exploration is essential. It is far from enough to rely solely on manpower to detect the ocean, and to a large extent must rely on ocean detection tools. At present, there are mainly two types of underwater vehicles used by developed countries to monitor the underwater environment; one is the underwater self-driving vehicle (AUV) that relies on batteries to provide energy. Generally, it is several kilometers to hundreds of kilometers, and the maximum is no more than 1000 kilometers. The operating time is limited, usually from several hours to tens of hours; the other is underwater glider. In 1989, Henry Stommel proposed an original concept.

Problems solved by technology

At present, there are mainly two types of underwater vehicles used by developed countries to monitor the underwater environment; one is the underwater self-driving vehicle (AUV) that relies on batteries to provide energy. Generally, it is several kilometers to hundreds of kilometers, and the maximum is no more than 1000 kilometers. The operating time is limited, usually from several hours to tens of hours; the other is underwater glider. In 1989, Henry Stommel proposed an original concept. Ingeniously transform the gravity and buoyancy of objects into forward driving force. In 1995, SLOCUM manufactured a prototype. In 1999, Seaglider and Spray successfully developed an underwater glider, which only provides very little energy and has a range of more than 2000 kilometers. The underwater voyage time can reach hundreds of days or even nearly a year, but the underwater glider can only do zigzag navigation underwater, and its track and positioning control is difficult, or even impossible, and the speed is relatively slow
