Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

[0026] The fins of the imitation beaver hind limbs shown in the accompanying drawings, the front side of the flipper support is the flipper upper shelf plate 26 and the flipper lower shelf plate 27 arranged at intervals up and down; two steering gears 1 are installed on the flipper upper shelf plate, and the four toes The components have the same structure and are all hinged on the hinged lugs on the front side of the flipper upper shelf and the flipper lower shelf through plug bolts to imitate the toes of the beaver flippers; the four toe components are also connected with a film 34 (preferably a silicone film ) to facilitate paddling. A transmission shaft that can cooperate with the rope winding wheel 2 and has a vertical axis is arranged between the upper and lower shelf plates of the flippers. The ...

Abstract

The invention belongs to the technical field of robots. The purpose is to provide a flipper device imitating the beaver's hindlimb, which should have the characteristics of simple structure and high propulsion efficiency. The technical solution is: a flipper device imitating the hind limbs of a beaver, characterized in that: the device includes a linkage mechanism and flippers hinged to the linkage mechanism; the flippers include two steering gears and a flipper bracket that can be fixed by the steering gear , the four toe assemblies with the same structure and are respectively swingably hinged on the flipper support, and a film connected with the four toe assemblies to facilitate water strokes.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a flipper propulsion device imitating a beaver hind limb. Background technique [0002] Underwater robots in the traditional sense that we are familiar with use propellers to generate propulsion; Its energy efficiency is less than 40%, and a series of problems such as eddy currents will be generated, which will greatly hinder the work of our robots. [0003] In today's field of underwater robots, various underwater robots are gradually being applied in reality, and all of them have achieved good results. In our research on underwater robots, the design and research of the propulsion mechanism is an indispensable part of the underwater robot design. The performance of the propulsion mechanism is directly related to the propulsion speed and propulsion efficiency of the robot. After millions of years of development, amphibians can survive in complex and changeable envi...
