Bionic flexible cable-driven manta ray based on marine ranching underwater environment detection

Abstract

The invention relates to the technical field of underwater navigation and detection devices, and provides a bionic flexible cable-driven manta ray based on marine ranching underwater environment detection. The manta ray comprises a manta ray body, a manta ray tail and a pair of bionic flexible cable-driven pectoral fins, one bionic flexible cable-driven pectoral fin is connected with the left sideof the manta ray body through a first drive mechanism, and the other bionic flexible cable-driven pectoral fin is connected with the right side of the manta ray body through a second drive mechanism;and the manta ray tail is connected with the lower end of the manta ray body through a third drive mechanism. The bionic flexible cable-driven manta ray based on marine ranching underwater environment detection is applicable to observing of the distributing state of ocean current around a large marine ranching and marine environmental elements, due to the bionic characteristics, ocean current distribution is not affected during observation, disturbance to the environment is smaller, and the accuracy is higher; and total flexible bionic motion can be achieved, and the high propulsion efficiency is generated.

Description

technical field [0001] The invention relates to the technical field of underwater navigation and detection devices, in particular to a bionic flexible wire-driven manta ray based on the detection of the underwater environment of marine pastures. Background technique [0002] As an important technical means to explore and utilize the ocean and develop ecologically intelligent aquaculture, underwater vehicles have become one of the research hotspots in the field of aircraft. [0003] The University of British Columbia uses a memory alloy wire as a driver to establish a two-dimensional swing pectoral fin test platform. Singapore Polytechnic University has developed RoMan-II, an undulating underwater vehicle imitating ray-like long fins. According to the optimization results, the University of Virginia in the United States made a simple bionic pectoral fin physical model by using steering gear. Nanyang Technological University in Singapore designed a strip-shaped long-fin prope...
