A vertical mechanical jellyfish

Abstract

The invention belongs to the technical field of bionic machinery, and in particular relates to a vertical mechanical jellyfish. The invention includes more than two groups of bionic jellyfish feet uniformly distributed in the circumferential direction around the fixed shaft; the fixed shaft outer is provided with a transmission shaft that can perform reciprocating linear motion along the axis of the fixed shaft, and the transmission shaft forms a dynamic cooperation with the power output end of the linear power source; There is an avoidance hole in the middle section of the shaft in the radial direction, the coaxial sleeve outside the transmission shaft is set to the sleeve, and the connecting plate extends radially from the fixed shaft to the avoidance hole, and the directional sleeve is fixed with the connecting plate; the directional sleeve and the transmission The axis corresponds to the first hinge point, the second hinge point, the third hinge point and the fourth hinge point of the bionic jellyfish foot. The invention can use the high bionic action function of jellyfish, on the one hand, it can be used as a scientific and educational tool to show the actual action state of jellyfish in nature with its own high degree of simulation; on the other hand, it can also provide simulation basis for unmanned underwater vehicles .

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
