Robotic fish used for tail fin impetus research

Abstract

The invention discloses a robotic fish used for tail fin impetus research. A tail board, an elastic sheet and a tail handle are equivalent to a fishtail, a hull floats on the water surface, and the tail board, the elastic sheet and the tail handle extend underwater through a transmission column. The simple self-waterproof robotic fish is provided, the tail board, the elastic sheet and the tail handle are equivalent to the fishtail, the hull floats on the water surface, the tail board, the elastic sheet and the tail handle extend underwater through the transmission column, the front end of thetail handle is connected with a rectangular prism structure at the lower end of the transmission column through a clamping part, the effects that detachment is convenient and the driving torque is stable are achieved, the rear end of the tail handle is connected with the tail board through the elastic sheet, the elastic sheet is arranged to imitate flexible swings of the fishtail, and the swing frequency and the swing range of the tail handle are adjusted through a steering engine. The requirement for tail fin impetus research is met through the structure, the structure is simple, detachment and installation are convenient, cost is low, and a variable can be changed conveniently.

Description

technical field [0001] The invention relates to a robotic fish used for the research of caudal fin propulsion. Background technique [0002] At present, in order to realize the tail fin propulsion research of the fish tail, it is generally necessary to make a tail fin propelled bionic robot fish. The existing technology generally makes a shell that is basically the same shape as the fish, and then sets a complex transmission mechanism inside the fish-shaped shell. Therefore, the caudal fin of the robotic fish is driven from the inside, and it is necessary to ensure that the robotic fish is at a certain depth in the water. For this reason, a series of structures or devices that can ensure that the robotic fish is at a certain depth must be installed, which makes the design and processing of the robotic fish extremely complicated. When it is necessary to frequently adjust the size, driving force, etc. in order to obtain multiple sets of parameters for experimental research, th...

When it is necessary to frequently adjust the size, driving force, etc. in order to obtain multiple sets of parameters for experimental research, the complexity of this robotic fish greatly reduces the efficiency of the research process and delays the research process
