Embodiment Construction

[0021] 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.

[0022] like figure 1 As shown, a propulsion device imitating the swing of the tail of a beaver includes a frame 1, a motor 2, a pendulum mechanism and a transmission mechanism. Both the motor and the pendulum mechanism are arranged on the frame, and the transmission mechanism is used to transmit the power of the motor to drive the pendulum mechanism to move. Described motor adopts stepper motor.

[0023] The swing rod mechanism includes several swing rods 3 that are hinged front and back in sequence (the side near the stepping motor is the front). ). The front end of the first swing rod is rotatably hinged on the frame; all the swing rods are sleeves, and the transmission shaft 4 which can rotate around the axis of the sleeve is arranged in the other sleeves except the last swing rod. A bearing (om...

Abstract

The invention belongs to the technical field of robots, and aims to provide a propelling device swinging like beaver tails; and the device has the characteristics of simple structure, convenience to control and high thrust. The propelling device swinging like the beaver tails is characterized by comprising a frame with a motor, a swing rod mechanism rotationally hinged to the frame, and a transmission mechanism for transferring power of the motor to drive the swing rod mechanism to move; the swing rod mechanism is formed by hinging multiple swing rods end to end in sequence; besides of the last swing rod, the other swing rods are provided with transmission shafts capable of rotating around the axes of the swing rods; the transmission mechanism comprises transmission shafts arranged in the swing rods, universal joints for transferring the power of the motor to the transmission shafts, and multiple bevel gear sets for driving all the swing rods to move; and the universal joints are arranged between a rotating shaft of the motor and the transmission shaft of the first swing rod and between the transmission shafts of the front and latter two swing rods.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a propelling device imitating the swing of the tail of a beaver. Background technique [0002] In the field of underwater robots in the traditional sense, we often use propeller rotation as the propulsion method, and there are various technical problems in this propulsion method. Underwater robots used as propellers have defects such as low propulsion efficiency, low reliability, high energy consumption, poor maneuverability, and large structural size and weight, and also produce eddy currents and noise pollution, which have a greater impact on the work of the robot. However, much improvement is still needed. [0003] Nowadays, by imitating the propulsion mode of amphibians, research on underwater robots with high efficiency and high mobility has gradually become the main goal pursued by researchers and scholars in various fields, and various underwater robots are gra...
