Skeleton structure of electromagnetic mechanical fish

Abstract

The invention discloses a skeleton structure of an electromagnetic mechanical fish. A bar component is a component for simulating a fish backbone, the bar component is composed of more than eight plastic bars which are connected pairwise, the plastic bars are connected by using universal joints, two side walls of each plastic bar are connected with bar electromagnets mutually perpendicular to the plastic bar in a mirror symmetry mode, the bar electromagnets are connected with a power supply arranged on the plastic bar through a switch circuit, two adjacent bar electromagnets are connected by an elastic component, the bar electromagnets are components for simulating a fishbone, the length of the bar electromagnet is gradually reduced along the direction from the front part to tail part of the fish backbone simulated by the bar component 1, and the distances between every two adjacent bar electromagnets are gradually reduced along the direction from the front part to tail part of the fish backbone simulated by the bar component. According to the skeleton structure disclosed by the invention, a defect that skeletons of simulated fishes in the prior art are only driven by a single section or two sections, so that the movement of the skeletons is stiff, and the practical value is difficult to improve is avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical fish, and in particular relates to a skeleton structure of an electromagnetic mechanical fish. Background technique [0002] At present, the skeleton structure of the artificial fish is nothing more than a connecting rod structure or a reciprocating structure or a circular motion structure, such as an electric motor, a gasoline engine, and a diesel engine. If adopt jet type or engine in addition, because be in water, lose a large amount of oxygen-containing environment, be difficult to use for a long time, the resistance in water is bigger. In view of the research on alternatives to propellers, some models of artificial fish drive have appeared, but they are not flexible enough. The skeletons of the present artificial fish are only driven by a single joint or a double joint, and the movements are stiff. And the practical value is difficult to improve.

Problems solved by technology

In addition, if a jet or engine is used, because it is in water, it will lose a large amount of oxygen-containing environment, and it is difficult to use it for a long time, and the resistance in water is greater.

In view of the research on alternatives to propellers, some fish drive models have appeared, but they are not flexible enough

The skeleton of the current artificial fish is only driven by a single joint or a double joint, and the movement is stiff

And it is difficult to improve the practical value
