Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the specific timely scheme of jet type biomimetic underwater vehicle of the present invention is described.

[0024] Such as figure 1 Shown, be the basic principle schematic diagram of the single elastic water-absorbing water-spraying cylinder type jet-type bionic underwater vehicle of the present invention, it comprises motor 201, gear, drive shaft 202, half gear 203, rack 204, elastic water-absorbing water-spraying cylinder 3, The nozzle 503 and the nozzle angle adjustment mechanism 5 are driven by the motor 201 to drive the half gear 203 on the transmission shaft 202 to rotate and drive the rack 204 to move back and forth, so that the elastic water-absorbing water spray tube expands and contracts alternately, and the expansion and contraction of the elastic tube is used to realize from The water suction of the water inlet and the water spraying of the nozzle 503 are carried out alternately.

Abstract

The invention relates to a spraying type simulative underwater vehicle and a working manner thereof, and belongs to the function simulation in the technical field of robot simulation. The spraying type simulative underwater vehicle comprises a shell, a propelling mechanism, a transmission mechanism, a sinking and floating mechanism, a spray pipe angle regulating mechanism and a power supply and control system. According to the spraying type simulative underwater vehicle, by simulating water absorbing and spraying modes of marine organisms, such as cuttlefishes and salps, and by utilizing intermittent and regular water absorbing and spraying operations of four elastic water absorbing and spraying drums, the continuous water spraying of a front spray head and a back spray head of the underwater vehicle is realized; by controlling deflection angles of the spray heads, the regulation of a motion direction of the underwater vehicle is realized. The spraying type simulative underwater vehicle can be applied to the related fields of underwater detection, underwater tracking, underwater rescue and the like.

Description

technical field [0001] The invention relates to a jet-type bionic underwater vehicle and its working method, belonging to the technical field of robot bionics. Background technique [0002] As early as the end of the 19th century, jet propulsion was used as a special propulsion device in ship propulsion. With the continuous development of the shipbuilding industry, propulsion technology has also undergone tremendous changes, from traditional propeller propellers to today's various characteristic pump jet propulsion, magnetic fluid propulsion and solid rocket propulsion. [0003] Cuttlefish is a common animal in the ocean, belonging to the mollusk phylum cephalopod subclass squid order. They rely on the special way of jet and fin wave compound propulsion to realize swimming, not only can swim flexibly, but also can realize swimming actions such as rolling and fast retreat. The squid-like robotic fish developed by Harbin Institute of Technology uses the heat shrinkage ...
