Embodiment Construction

[0025] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] Such as Figure 1-9 As shown, the robotic fish pectoral fin propulsion mechanism includes two left and right pectoral fin mechanisms that are completely symmetrical along the central axis of the fish shell. The left and right pectoral fin mechanisms have the same structure, which meets the design requirements of the robotic fish. independent action. The pectoral fin mechanism includes a motor support 1, a power source motor 2, a gear pair 3, a rotating central axis 4, a central axis support 5, a rotating support 6, a first motor 7, a hinge 8, a sliding cylinder 10, a ball pair 11, The pectoral fin 12, the motor support 1 and the central axis support 5 are fi...

Abstract

The invention discloses a novel robot fish pectoral fin propelling mechanism, which comprises two pectoral fin mechanisms which are symmetrically arranged on the left and the right of the central axis of a fish body shell. The structures of the two pectoral fin mechanisms are same. Each pectoral fin mechanism comprises a motor support, a power source motor, a gear pair, a rotating center shaft, a center shaft support, a rotating support, a first motor, a hinge piece, a sliding sleeve, a similar ball pair and a pectoral fin, wherein the motor support and the center shaft support are fixedly arranged on the fish body shell, the power source motor is fixedly arranged in the motor support, the output shaft of the power source motor is connected with the gear pair, the gear pair is assembled on the rotating center shaft, the rotating center shaft is supported by the motor support and the center shaft support, one end of the rotating center shaft is connected with the rotating support, the first motor is tightly fixed on the rotating support, the output end of the first motor is hinged with one end of the sliding sleeve through the hinge piece, the other end of the sliding sleeve is slideably connected with the similar ball pair and the similar ball pair is fixedly connected with the pectoral fin. The novel robot fish pectoral fin propelling mechanism has the characteristics of multiple movement patterns, and the high flexibility and the high sealing performance of the traditional mechanical mechanism.

Description

technical field [0001] The invention belongs to an electromechanical device, in particular to a pectoral fin pushing mechanism of a robot fish. Background technique [0002] With the increasing importance of ocean rights and interests, the importance of ocean exploration, protection and utilization also increases. Most of the existing ships and submersibles that perform tasks in water use propellers as the main propulsion method, which has relatively large limitations in terms of noise and wake vortex control. As a product of natural evolution, fish has excellent swimming ability in water. The study of its swimming mechanism will help provide new propulsion methods for the new generation of ships and submersibles. In nature, the propulsion methods of fish are mainly divided into two categories, namely the body / caudal fin propulsion method and the pectoral fin propulsion method. The current research mainly focuses on the former, and there are relatively mature research resu...
