Stagewise buoyancy drive heavy-load underwater vehicle

Abstract

The invention discloses a stagewise buoyancy drive heavy-load underwater vehicle. The stagewise buoyancy drive heavy-load underwater vehicle comprises a heaving line, a bow outer shell, a front cabinsection, a middle cabin section, a rear cabin section, an antenna cabin section, a tail rudder section and a tail propeller, wherein the heaving line, the bow outer shell, the front cabin section, themiddle cabin section, the rear cabin section, the antenna cabin section, the tail rudder section and the tail propeller are sequentially arranged from front to back. A front buoyancy adjusting moduleand a transverse propeller are arranged in the front cabin section, and a power module, a control module and a posture adjusting module are arranged in the middle cabin section. A rear buoyancy adjusting module is arranged in the rear cabin section, and two gliding wings are arranged on the two sides of the rear cabin section. A wireless communication antenna and an iridium satellite and Beidou antenna are arranged on the upper portion of the antenna cabin section, and a load rejection module is arranged on the lower portion of the antenna cabin section. A cross-shaped rudder mechanism is arranged in the tail rudder section. The tail propeller is mounted behind the tail rudder section. The heaving line is located at the foremost end of the bow outer shell and connected with the bow outershell through a bolt. All stages of oil pumps of the two buoyancy adjusting modules can be simultaneously switched on, the oil drainage time and the oil return time of the vehicle are shortened, and the gliding performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of new marine vehicles, in particular to a hybrid-driven large-scale heavy-duty underwater vehicle that adopts a hierarchical buoyancy adjustment system. Background technique [0002] With the deepening of marine scientific research, underwater glider platform technology has developed rapidly. Its strong endurance, long range, and strong concealment make it very suitable for the measurement of marine biological, chemical, and physical parameters. One of the commonly used underwater mobile observation platforms. [0003] At present, in the field of marine exploration at home and abroad, portable underwater vehicles are very mature, but their carrying capacity is small, and they are not suitable for carrying a variety of detection sensors, and cannot simultaneously measure various marine biochemical parameters. Therefore, the large-scale heavy-duty underwater vehicle technology with multiple sensor carrying capabilitie...

AI Technical Summary

Problems solved by technology

In recent years, some domestic scientific research institutes have started the research and development of large-scale heavy-duty underwater gliders, but related products have problems such as single buoyancy adjustment methods, insufficient adjustment accuracy, and high energy consumption. At the same time, the energy density is low and the range is short. unresolved issues

For example, the AUV underwater vehicle seen in the market now has sufficient carrying capacity, but it is completely propelled by the tail propeller, which has low efficiency, high energy consumption, short voyage, and is not suitable for long-range observation operations; while smaller Although the current underwater glider has the characteristics of constant voyage and low power consumption, its carrying capacity is limited, and it does not have the function of simultaneous measurement of multiple biochemical parameters.
