Self-adaptive sound wave fish-luring-and-herding dual-purpose underwater vehicle

Abstract

The inventiondiscloses a self-adaptive sound wave fish-luring-and-herding dual-purpose underwater vehicle. The underwater vehicle comprises a front portion, a middle portion and a rear portion. A steering engine is arranged inside the front portion and connected with a water absorbing rudder, and the heading direction of the underwater vehicle is changed by changing the rudder angle of the underwater vehicle; a motor A is arranged inside the rear portion and connected with a propeller located at the tail portion of the underwater vehicle through a coupler and a sleeve, a partition plate is arranged between the front portion and the middle portion as well as between the middle portion and the rear portion, and the front portion is connected with the rear portion in a threaded mode; and a signal emitting control system, a battery, a water tank, a gear and a motor B are arranged in the middle of the underwater vehicle from top to bottom. A sound wave emitting device and the underwater vehicle are combined, a sound source travels in an automatic / remote control mode along with swimming of fish schools, the frequency can be changed at any time according to the luring and herding effect, and the optimal effect is achieved. A manual or automatic system is not needed for real-time rigor control, the operating difficulty in fish luring and herding is lowered, and a method for protecting fish ecology is achieved.

Description

technical field [0001] The invention relates to a submersible, in particular to a dual-purpose submersible for self-adaptive sound wave luring and driving fish. Background technique [0002] At present, the management and development of water resources in my country has entered a new stage. More and more flow-blocking structures have been built on the big rivers in our country, which has changed the inherent natural characteristics of the rivers, and has a great impact on the water environment and water quality in the upstream and downstream of the gates and dams. Ecological environmental conditions and fish habitat environmental factors (such as water level, flow, water temperature, etc.) have a relatively large impact, which may directly lead to the extinction of some anadromous fish species. In an era that increasingly emphasizes the harmonious coexistence between man and nature, fishways, as an engineering measure to protect biological resources, have been more and more i...

Problems solved by technology

In order to solve the problems of guiding fish from the river channel to the entrance of the fishway and collecting fish in the reservoir, this project proposes to design a dual-purpose intelligent submersible with adaptive sound waves to lure and drive fish, so as to reduce energy consumption, improve the efficiency of fish passing, and reduce the number of fish. casualties
