Hybrid type underwater sailing device

Abstract

A hybrid underwater vehicle has a skeleton composed of a head cover, a body cover, and a tail cover; a delta wing installed outside the body cover, and a vertically fixed tail rudder; an altimeter arranged on the lower side of the tail cover; The navigation module in the head cover; the middle pressure chamber arranged inside the body cover; the left pressure chamber and the right pressure chamber arranged inside the body cover; the underwater acoustic communication module arranged in the body cover; The buoyancy drive system, control system, pitch adjustment block and pitch adjustment block support rod for supporting the pitch adjustment block in the fuselage cover and the intermediate pressure chamber; two ducted propeller propellers that are symmetrically fixed and connected to the tail of the tail cover . The present invention simultaneously adopts a delta wing with both gliding performance and AUV operational performance as the wing of the aircraft, and is equipped with corresponding measurement sensors and task modules, which can realize monitoring and surveying of a wide range of waters for a long time, and can also precisely measure specific targets. Rapid monitoring, investigation, tracking and other operations.

Description

technical field [0001] The invention relates to underwater navigation. In particular, it relates to a hybrid underwater vehicle that integrates the functions of a glider and an AUV, and can be equipped with measurement sensors to monitor and survey a wide range of waters for a long time. Background technique [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 several hundred kilometers, and the maximum is no more than 1000 kilometers. The operating time is limited, usually hours to tens of hours; the other is the unde...

Problems solved by technology

At present, there are mainly two types of underwater vehicles used by developed countries for underwater environment monitoring; one is the underwater autonomous 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 hours to tens of hours; the other is the underwater glider. Henry Stommel proposed an original concept in 1989. In 1995, SLOCUM produced 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 2,000 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
