Abstract

The invention relates to underwater propulsion devices, particularly to a jellyfish swimming type serial bionic underwater propulsion device which aims at solving the problems that the existing jellyfish swimming type bionic propulsion device is complex in mechanical structure, large in movement control difficulty, low in system integration level and not suitable for micro miniaturization, the high efficiency of the jelly retraction water-spraying state cannot be continuously maintained in one movement cycle, and the difference with the propulsion behavior of real jellyfishes is large. The jellyfish swimming type serial bionic underwater propulsion device comprises N power supply and control modules and also comprises N-1 inter-stage connecting shafts and N stages of propulsion machine jellyfishes, wherein N is a positive integer and N is not less than 2; every two adjacent stages of propulsion machine jellyfishes are connected through the corresponding inter-stage connecting shaft; the inter-stage connecting shafts and the propulsion machine jellyfishes are coaxial; one end of every inter-stage connecting shaft is connected with an abdominal cavity top cover of the corresponding stage of propulsion machine jellyfish; the other end of every inter-stage connecting shaft is connected with an abdominal cavity base of the other corresponding stage of propulsion machine jellyfish; every abdominal cavity base is embedded into the bottom of a bionic flexible body. The jellyfish swimming type serial bionic underwater propulsion device is applied to the marine research and other fields.

Description

technical field [0001] The invention relates to an underwater propulsion device, in particular to a serial bionic underwater propulsion device, which belongs to the field of bionic underwater propulsion systems. Background technique [0002] The bionic underwater propulsion device is a mechanical system developed and designed with reference to underwater bionic prototypes (such as fish, turtles, etc.). It has the characteristics of high efficiency and quietness, and is expected to replace some existing propeller propulsion systems. And commercial value, attracting more and more researchers to work in this area. Generally speaking, the propulsion forms of underwater bionic prototypes can be roughly divided into three forms: body caudal fin propulsion (BCF), pectoral fin propulsion (MPF), and jet propulsion (JP). From the perspective of machine bionics, based on BCF and MPF The mechanical system of the propulsion prototype has the disadvantages of complex structure and diffic...
