Abstract

The invention discloses a fin ray-free amphibious propelling device with bionic undulating fins, which is characterized in that two end fixed type crankshaft swing rod transmission modules are arranged on corresponding bottom plates correspondingly, and the front ends and the rear ends of the two bottom plates are connected with a front waterproof steering engine amphibious mode switching module and a rear waterproof steering engine amphibious mode switching module correspondingly; the front and back waterproof steering engine land and water mode switching module is used for maintaining the state of the bottom plate; each end fixed type crankshaft swing rod transmission module is connected with one flexible fin-ray-free flexible fin through the corresponding drive swing rod mechanism, and the joint of each drive swing rod mechanism and the corresponding flexible fin-ray-free flexible fin is provided with a rotational degree of freedom to drive the fin surface of the corresponding flexible fin-ray-free flexible fin to achieve fluctuating motion. The problems that an existing amphibious robot is complex in transmission mechanism, complex in amphibious mode switching, large in wheel paddle driving noise, low in flexibility and large in environment disturbance, the movement speed of fluctuation fins driven by a conventional steering engine is low, and a traditional cam and crankshaft connecting rod mechanism is low in bearing capacity and cannot conduct amphibious movement are solved.

Description

technical field [0001] The invention belongs to the technical field of amphibious robots, in particular to a bionic fluctuating finless finless amphibious propulsion device. Background technique [0002] China has millions of square kilometers of sea area and tens of thousands of kilometers of continental coastline. With the development of my country's national ocean development strategy, it is necessary to study amphibious propulsion devices that can meet the needs of efficient underwater propulsion and high maneuverability on land. Amphibious robots replace humans in military intelligence collection and offshore area alert tasks, which is of great strategic significance for improving the technological level of unmanned weapons in our country. In addition, amphibious robots are also widely used in civil fields such as mineral resource exploration and development and marine life protection. prospect. [0003] Current traditional amphibious robots, such as amphibious boats and...
