specific Embodiment approach 1

[0016] Specific implementation mode one: combine Figure 1-Figure 6 Illustrate that the skate-like underwater vehicle propelled by double undulating pectoral fins in this embodiment includes a power supply and control module 3, which also includes an abdominal cavity assembly and two sets of undulating pectoral fin assemblies 5; the abdominal cavity assembly includes an abdominal cavity chassis 1 and an abdominal cavity roof 7;

[0017] Each set of undulating pectoral fin assemblies 5 includes a flexible wing 19, a first piezoelectric fiber composite material driving joint 18, two second piezoelectric fiber composite material driving joints 17 and two third piezoelectric fiber composite material driving joints 16, the flexible wing 19 is embedded with a first piezoelectric fiber composite driving joint 18, two second piezoelectric fiber composite driving joints 17 and two third piezoelectric fiber composite driving joints 16 arranged side by side, the first piezoelectric fiber ...

specific Embodiment approach 2

[0020] Specific implementation mode two: combination Image 6 Note that the flexible wings 19 in this embodiment are made of silicone. With such setting, the chemical properties are stable, and the mechanical strength is relatively high, which meets the design requirements and actual needs. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific implementation mode three: combination figure 2 Note that both the abdominal cavity chassis 1 and the abdominal cavity roof 7 in this embodiment are made of silica gel. The fish body of this embodiment has a certain degree of flexibility, which is relatively similar to the physical characteristics of rays in nature, so a better bionic effect can be obtained. Others are the same as in the first or second embodiment.

Abstract

The invention relates to a ray-imitated underwater vehicle, in particular to a double-fluctuation pectoral-fin cooperative-propel ray-imitated underwater vehicle, aiming to solve the problems that existing underwater vehicles are complicated in mechanical structure, bionic pectoral-fin propel type underwater vehicles are difficult in motion control and single in motion type and bionic effect is different from real pectoral-fin propel. The double-fluctuation pectoral-fin cooperative-propel ray-imitated underwater vehicle comprises a power supply and control module, an abdominal cavity component and two sets of fluctuation pectoral-fin components; the abdominal cavity component comprises an abdominal cavity baseplate and an abdominal cavity roof; each set of fluctuation pectoral-fin component comprises a flexible wing, a first piezoelectric fiber composite driving joint, two second piezoelectric fiber composite driving joints and two third piezoelectric fiber composite driving joints, and the first piezoelectric fiber composite driving joint, the second piezoelectric fiber composite driving joints and the third piezoelectric fiber composite driving joints are embedded in the flexible wing in parallelly. The double-fluctuation pectoral-fin cooperative-propel ray-imitated underwater vehicle is used for marine science.

Description

technical field [0001] The invention relates to a skate-like underwater vehicle, which belongs to the field of bionic underwater vehicles. Background technique [0002] With the increasingly serious contradiction between the shortage of terrestrial resources and the increasing demand for energy in modern society, more and more governments and research institutions in countries and regions have set their sights on the ocean. A hot issue of development. However, since the ocean, especially the deep sea area, does not belong to the traditional living zone of human beings, in order to solve this problem, it is necessary to develop underwater vehicles, especially efficient, clean and environment-friendly underwater vehicles. [0003] Most of the existing underwater vehicles use the propeller as the propulsion mechanism. This method has many unavoidable shortcomings, such as large volume, heavy weight, high noise, low efficiency, and the disturbance of the surrounding fluid is ea...
