Problems solved by technology

There is a periodic alternating force in the propulsion of the tail fin, and the body of the bionic robot fish will sway periodically under the influence of the alternating force during the movement of the bionic robot fish, which is not conducive to the stability of the body of the bionic robot fish. The length is long and it is not easy to miniaturize; propeller propulsion mainly has the disadvantages of loud noise, low concealment, and poor movement flexibility, so it is difficult to play a role in the field of bionic robot fish

Abstract

The invention discloses a bionic robotic fish based on bionic fin and pump combined propulsion, which is used for oil-immersed transformer internal inspection. The bionic robotic fish comprises a headsection shell, a middle section shell and a tail section shell which are connected in sequence, wherein the head section shell is provided with an inspection camera, the two sides of the head sectionshell are symmetrically provided with two-degree-of-freedom bionic fin mechanisms respectively, the middle section is a sinking and floating control mechanism, the upper end of the sinking and floating control mechanism is provided with a balance control rudder bin, and the rear end of the tail section shell is provided with a pump type propeller. According to the two-degree-of-freedom bionic finmechanism, various complex combined motion modes such as advancing, retreating, ascending, diving and turning can be conveniently achieved, thereby being closer to the swimming state of a real fish,improving the swimming speed and maneuverability of the bionic fish at the same time, and improving he adaptability of the bionic fish to the narrow space.

Description

technical field [0001] The invention relates to a bionic robot fish based on the combination of bionic fins and pumps. Background technique [0002] Fish have survived on the earth for hundreds of millions of years, and have evolved a body structure and shape adapted to underwater movement, with efficient and stable swimming capabilities. Its high-efficiency and fast swimming, high maneuverability and low noise characteristics are beyond the reach of man-made aircraft. Humans have designed bionic robot fish based on the strong swimming ability of fish, and used bionic robot fish for underwater monitoring, investigation and resource detection and other activities. [0003] At present, the propulsion methods of bionic robotic fish mainly include caudal fin propulsion and propeller propulsion. There is a periodic alternating force in the propulsion of the tail fin, and the body of the bionic robot fish will sway periodically under the influence of the alternating force during...
