Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] like Figure 1-5 As shown, a bionic robotic fish pitch adjustment device includes a center of gravity block fixed bracket 2 and an upper pectoral fin swing fixed shell 6 arranged on the bionic robotic fish body; wherein, the center of gravity block fixed bracket 2 is fixed on the upper pectoral fin swing fixed shell 6 upper part.

[0030] The first steering gear 1 is rotated on the fixed bracket 2 of the center of gravity block, and the output shaft of the first steering gear is arranged horizontally. The upper surface of the fixed housing 6 is a horizontal plane, on which the second steering gear 3 is fixedly arranged, and the output shaft of the second steering gear 3 is vertically arranged, and the output shaft of the second steering gear 3 is fixedly connected with one end of the first connecting rod. The other end of a c...

Abstract

The invention discloses a bionic robotic fish pitching adjusting device. The device comprises gravity center block fixing supports and an upper pectoral fin swing fixing shell, all of which are arranged on a bionic robotic fish body, wherein the gravity center block fixing supports are fixed to the upper portion of the upper pectoral fin swing fixing shell. A current mainstream gravity center mechanism adopts a lead screw to push a gravity center block, the occupied size is large, circular rotation is adopted for changing the position of the gravity center so that the size of the mechanism canbe effectively reduced, a side inclination gravity center block is additionally arranged, the position of the gravity center can be changed in multiple dimensions, and more complicated motion can beachieved; and more motion modes and motion directions are provided from traditional forward swimming through a tail to backward swimming through pectoral fin swings, and the turning radius of a bionicrobotic fish can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of bionic robot fish, and specifically relates to an adjustment device with a center of gravity and a pectoral fin direction changing mechanism, which can realize forward and backward, left and right turning, floating up and down, and sideways tilting swimming of the bionic robot fish in water. Background technique [0002] Generally, human beings can only move and work in clean water basins with sufficient water. In shallow water and sewage environments, they cannot move forward due to the harsh environment and other reasons. The bionic robot fish came into being in such an era. The bionic robot fish can be used in clean water. It can gallop arbitrarily in the waters, and it can also replace manual long-term underwater operations in narrow pipelines, polluted environments, and waters with zero visibility. Bionic robotic fish are generally equipped with small sonar systems, infrared systems, water quality mo...
