Jellyfish-imitating underwater vehicle

Abstract

A jellyfish-imitating underwater vehicle is characterized in that the interior of the underwater vehicle is a multi-layer rectangular shell body made of acrylic; six layers of power system mounting plates are uniformly distributed inside the shell body; half-moon head pushing rods stretch out of the shell body, and the head parts of the pushing rods are in half-moon shapes; two pushing rods stretch out at the two sides of each layer of the rectangular shell body correspondingly; the stretching directions of the pushing rods of each upper layer and each lower layer are perpendicular; sealing between the shell body and the half-moon head pushing rods adopts a mode that sealing rings are additionally mounted in gaps between a cabin body and supporting rods, and one ends of elastic plastic thin films (similar to a material of a balloon) are wound on the supporting rods, and the other ends of the thin films are pasted on the cabin body; the external surface of the underwater vehicle adopts a flexible latex wing film for imitating an epidermis of a jellyfish; the heads of the pushing rods are attached to the latex wing film to support the latex wing film to be opened; three sets of pushing rods are located in the elongation direction of the cuboid shell body, and the original positions of stretching and retracting of the pushing rods are controlled through the different phases of an internal steering engine; and the positions of the pushing rods are optimized, the mutually-perpendicular pushing rods form a cross shape to be one set, so that sinusoidal waves are simulated as much as possible by using three-set points, and the possibility of water absorbing and draining is achieved maximally.

Description

technical field [0001] The invention relates to the field of underwater vehicles, in particular to a jellyfish-like underwater vehicle. Background technique [0002] my country's sea area is vast, and defense and reconnaissance are more difficult. In recent years, due to the rapid development of China's economy and society, some western countries have created a "China threat theory", so they try to contain China's development. Among them, provocations to China's territorial waters have intensified, such as the Diaoyu Islands, Huangyan Island, and the South China Sea incident, which have aroused the indignation of the Chinese people. Therefore, it is particularly important to defend our country's territorial waters and vigorously develop the navigation industry. [0003] At the same time, our country attaches great importance to sea rights and the increasing use of marine resources, and we are increasingly dependent on the ocean. However, the motion principles of today's u...

Problems solved by technology

[0006] To realize the stable operation and low noise of the imitation jellyfish underwater vehicle in the water, the following points need to be solved, and the power problem will bear the brunt. Harmonics are composed of simple harmonic vibrations of countless particles, but this project can only subdivide the simple harmonic vibration particles (curved support rods) for a limited number of times, so that these simple harmonic vibration particles drive the surrounding membranes, so that the entire wing The longitudinal section of the membrane presents an approximate simple harmonic wave, and at the same time, in order to improve the movement efficiency, it is necessary to optimize the placement position of the support rods; due to the large number of support rods, the sealing technology of the holes passing through the cabin is particularly important; the pressure difference Due to the water speed inside the latex membrane is faster than that on the outside, the membrane will be deformed by water pressure during high-speed navigation, which may affect the efficiency of the aircraft's power system
