Embodiment Construction

[0026] The robotic fish includes a power supply and control module 1, an active power module 2, a pectoral fin folding module 3, a direction adjustment module 4, and a fish body body 5, wherein the power supply and control module 1 and the active power module 2 are all placed in the fish body body 5. In the airtight cavity formed by the shell 6 and the cover plate 7, the pectoral fin folding module 3 is installed outside the airtight cavity formed by the shell 6 and the cover plate 7 in the fish body body 5, and the direction adjustment module 4 is placed on the fish body body There are 8 fishtails in 5.

[0027] The pectoral fins of the robot fish are fully retracted before use. After the robot fish is launched into the water, the power supply and control module 1 instructs the auxiliary motor 10 to rotate, which drives the screw 11 to rotate, thereby driving the small slider 12 to slide in the motor cylinder 9, so that The pectoral fin of robotic fish fully unfolds, and now ...

Abstract

The invention discloses a bionic robot fish with pectoral fins foldable. A fish body main body, a power supplying and control module, a main power module, a pectoral fin folding module and a directionadjusting module are included; and the problems that an existing underwater vehicle is complex in mechanical structure, movement control of a bionic pectoral fin propelling type underwater vehicle isdifficult, and a movement type is singular are solved; and a structure utilizing a cam roller to transmit motor movement to drive the pectoral fins to swing is adopted by the main power module, and the bionic robot fish with the pectoral fins foldable is simple and reliable in mechanical structure and implementation is easy. According to the bionic robot fish with the pectoral fins foldable, thepectoral fins are foldable, during the movement of the robot fish, the pectoral fins of the robot fish can be slightly recycled, the backswept angle is increased, the resistance of water is reduced, the energy loss is reduced, and the speed of movement of the robot fish is increased; the direction adjusting module of the bionic robot fish with the pectoral fins foldable uses auxiliary wings, a rudder and an auxiliary wing manipulating mechanism, due to the relationship between the fluid pressure intensity and the flow speed, the robot fish can achieve steering, floating-up movement and diving;and the bionic robot fish with the pectoral fins foldable can be used for ocean exploration, seabed ecological disaster rescuing and the like.

Description

technical field [0001] The invention belongs to the technical application field of bionic robot fish, in particular to a bionic robot fish with foldable pectoral fins. Background technique [0002] In recent years, the development and utilization of deep-sea resources have provided extensive background and needs for the research of underwater robots. Many countries in the world attach great importance to the research of underwater robot technology, regard underwater robot as a key research project and vigorously develop it. However, the current underwater robots mostly use traditional propellers as propellers, which are large in size, heavy in weight, high in energy consumption, low in overall efficiency, lagging in instantaneous response, poor in motion flexibility, and accompanied by large noise and tail. eddy. Low propeller efficiency is also one of the main reasons for the energy bottleneck of underwater robots. These disadvantages of propeller propulsion are not cond...
