Underwater biomimetic robotic fish

Abstract

The invention relates to an underwater biomimetic robotic fish which comprises a main cabin body, pectoral fins respectively arranged on both sides of the main cabin body, a driving module arranged on the rear part of the main cabin body, a fan-shaped tail fin arranged on the rear part of the driving module and connected with the driving module through upper and lower connecting rods, and a dynamic seal mechanism arranged between the upper connecting rod and the output end of the driving module; the main cabin body comprises a casing with windows on left and right sides, and a bottom window, each window is respectively connected with a side cover and a bottom cover, and a sliding block device is connected with the bottom cover; the sliding block device comprises a front bracket and a rear bracket arranged on the bottom cover, the front and rear brackets are connected with a screw rod and a polished rod through bearings, a sliding block is nested on the screw rod and the polished rod, one end of the screw rod penetrates through the rear bracket to connect with a lower gear, the lower gear is meshed with an upper gear, the upper gear is fixedly connected the output end of a serial motor, and the serial motor is fixed on the upper part of the rear bracket. The invention has good underwater three-dimensional movement ability, certain environment adaptability, stability and reliability, flexible movement, is used for underwater resource exploration, marine salvage, rescue and other tasks, and also can play a significant role in future sea battle missions.

Description

technical field [0001] The invention relates to a robotic fish, in particular to an underwater bionic robotic fish with a slider type submersible raising mechanism. Background technique [0002] With the economic development of various countries and the growth of population, human beings consume more and more resources, while the resources on land are getting less and less. Therefore, energy shortage has become a major problem facing the world in the 21st century. The vast ocean occupies 71% of the earth's surface area, and the seabed is rich in mineral resources. In today's shortage of resources, the development of the ocean has undoubtedly become an important strategic goal and the focus of competition for all countries in the world. However, due to the very harsh environment of the underwater world, it has brought unprecedented challenges to the development work. As a high-tech means, underwater robots have played an important role in the field of ocean development and u...
