Profile modeling mechanical ray based on water spray promoting manner

Abstract

A profile modeling mechanical ray based on a water spray promoting manner comprises a shell in a ray shape, a power device, a hydraulic device, a control device and a detection device. The shell is composed of a front shell body in the shape of a ray body and a rear shell body in the shape of a ray tail. The front shell body and the rear shell body are fixedly connected through screws. A detachable upper top cover is formed on the top of the front shell body. An engine compartment vertically corresponding to the upper top cover is arranged in the front shell body. A left compression compartment is formed in the left side of the engine compartment. A right compression compartment is formed in the right side of the engine compartment. A first front channel and a second front channel which communicate with the external environment are formed in parallel in the portion of the front end of the left compression compartment in the front and back direction. A first valve is installed at the front end of the first front channel, and a second valve is installed at the front end of the second front channel. The profile modeling mechanical ray is reasonable in design, the shell in the ray shape is adopted, a heading manner that compression boards are driven by power, so that water is sprayed backwards in the compression compartments is used, the tail can swing leftwards and rightwards, and a tail wing can be controlled by a steering engine to rotate up and down.

Description

technical field [0001] The invention belongs to the field of profiling diving, in particular to a profiling mechanical ray based on a water jet propulsion method. Background technique [0002] At present, submersibles generally use low-efficiency propellers as propellers, which will produce "cavitation" when submersible, which not only reduces efficiency, but also damages the propulsion device, and at the same time generates a lot of noise. Propeller propulsion can no longer meet the economic and technical requirements in the process of human development. In recent years, many institutions and departments have begun to be keen on the research of bionic fish, and the research direction of fish bionics mainly relies on the swing of the tail of the fish to generate reverse thrust to move forward. The propulsion method has little power and low efficiency. And the concealment of the bionic fish utilizing these two kinds of propellers is poor. Contents of the invention [0003...
