Adaptive sonic lure and drive fish dual-purpose submersible

Abstract

The invention discloses a dual-purpose submersible for self-adaptive sound wave luring and driving fish; the submersible is divided into a front part, a middle part and a rear part; The course of the submersible; the motor A is set in the rear, and the motor A is connected to the propeller at the tail of the submersible through a coupling and a sleeve. The front and the middle and the middle and the rear are all designed with partitions, and the front and the rear are connected to each other. The joints of the submersible are designed in the form of threads; the middle part of the submersible is provided with a signal emission control system, a battery, a water tank, a gear and a motor B from top to bottom; The method makes the sound source sail with the swimming of the fish, and can change the frequency according to the lure effect at any time to achieve the optimal effect. The invention does not need manual or automatic system for real-time strict control, reduces the operation difficulty of luring and collecting fish, and is a method for protecting fish ecology.

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
