Embodiment Construction

[0023] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings, but the present invention is not limited to the following embodiments.

[0024] In the swing mechanism imitating beaver tail shown in the accompanying drawings, the motor 1 is arranged on the frame 22, and the swing plate mechanism is rotatably hinged on the frame to form a tail imitating the drive of a beaver, and the transmission mechanism transmits the power of the motor to drive Swing plate mechanism; in the transmission mechanism, the slider crank mechanism is driven by the motor, the rack and pinion mechanism is driven by the slider crank mechanism, and the rope winding wheel 8 that takes up the flexible rope is driven by the rack and pinion mechanism. The rack and pinion mechanism includes a rack fixed to the slide block 5 and a gear 6 driven by the rack; the rope winding wheel is in contact with the end face of the gear and is fixedly conn...

Abstract

The invention relates to an underground robot, and aims to provide a beaver tail motion-simulated swing mechanism; and the mechanism has the characteristics of high thrust force, high pushing efficiency and low weight, and is used as a pushing mechanism of the robot. The beaver tail-simulated swing mechanism is characterized by comprising a frame provided with a motor, a swing piece mechanism rotationally hinged to the frame to form a swinging tail, and a transmission mechanism for transferring the power of the motor to drive the swing piece mechanism; the transmission mechanism comprises a crank slide block mechanism driven by the motor, a rack gear mechanism driven by the crank slide block mechanism, and a rope winding wheel driven to wind a flexile rope repeatedly by the rack gear mechanism; and the swing piece mechanism is formed by hinging multiple swing pieces end to end in sequence from front to back, and hinge axles thereof are horizontally arranged.

Description

technical field [0001] The invention relates to an underwater robot, in particular to a swing mechanism imitating a beaver tail. Background technique [0002] Underwater robots in the traditional sense mainly use propeller propulsion as their propulsion method; the propeller propulsion method has various defects such as large energy consumption, low reliability, low propulsion efficiency, poor maneuverability, etc., and will generate noise pollution and eddy currents, which are harmful to The work of the robot creates greater obstacles. [0003] In today's field of underwater robots, a variety of underwater robots are gradually being applied in practice, and all of them have achieved good results. In the research of robots, the design and research of the propulsion mechanism is an indispensable and important part. The performance of the propulsion mechanism is directly related to the propulsion speed and propulsion efficiency of the robot. Therefore, imitating the propuls...
