Vertical mechanical jellyfish

Abstract

The invention belongs to the technical field of bionic machinery, and particularly relates to a vertical mechanical jellyfish. The vertical mechanical jellyfish comprises more than two groups of bionic jellyfish feet which are uniformly distributed around a fixed shaft in the circumferential direction, a fixed shaft is sleeved with a transmission shaft capable of doing reciprocating linear motionalong the axis of the fixed shaft, and the transmission shaft is in power fit with the power output end of the linear power source. A receding hole penetrates through a middle section shaft body of the transmission shaft in the radial direction, the transmission shaft is coaxially sleeved with a directional sleeve, a connecting plate extends out of the receding hole in the radial direction of thefixed shaft, and the directional sleeve is fixed to the connecting plate. And the directional sleeve and the transmission shaft are correspondingly hinged with a first hinge point, a second hinge point, a third hinge point and a fourth hinge point of the bionic jellyfish foot. Through the high bionic action function on jellyfishes, on one hand, the jellyfishes can be used as a science and education tool, and the actual action state of the jellyfishes in the natural world is shown through the high simulation degree of the jellyfishes; and on the other hand, a simulation basis can be provided for the unmanned underwater vehicle.

Description

technical field [0001] The invention belongs to the technical field of bionic machinery, and in particular relates to a vertical mechanical jellyfish. Background technique [0002] Bionics is an interdisciplinary subject that combines engineering technology and biological science developed in recent years. The purpose is to analyze biological processes and structures, and use the obtained analysis results for future design. In bionics, through the understanding and analysis of jellyfish, it has been found that compared with wave-propelled fish, it has the advantages of concealed movement, small size, light weight, high flexibility and low metabolic rate, and can effectively use the water to swim. Characteristic, therefore, people are committed to realizing the biomimicry to jellyfish always. At present, on the one hand, jellyfish bionics is used in science and education publicity, such as science and technology museums, etc., to realize scientific and educational functions ...

AI Technical Summary

Problems solved by technology

In the bionic research of jellyfish, how to imitate the elegant movement of jellyfish is the key point. Most of the existing technologies are described in the invention title of "a bionic mechanical jellyfish" with the Chinese patent announcement number "CN108146599A": the jellyfish head, jellyfish body It is composed of jellyfish tail, among which, jellyfish body is equipped with various sensors, encoders, and control panels; jellyfish head is equipped with GPS locator, power indicator light and antenna; jellyfish tail is equipped with power supply and multi-functional expansion interface; Most of the existing technologies focus on signal control and neglect motion management. There are very few bionic studies on the most important marching motion of jellyfish. The scientific and educational effect is poor; and when used as underwater navigation equipment, the above-mentioned rigid foot movements obviously cannot achieve the ideal water propulsion effect, and can only rely on additionally loaded propulsion components such as propellers to realize the traveling function, which cannot be effective Using the inherent concealment of jellyfish, etc., needs to be solved urgently
