An automatically-rotating type fish reserve monitoring device

Abstract

The invention discloses an automatically-rotating type fish reserve monitoring device, and aims to provide an automatic-rotating type fish reserve monitoring device effectively increasing a visual angle scope of shooting / photographing a spawning site by a camera device or a photographing device. The automatically-rotating type fish reserve monitoring device comprises a buoyancy device, a connecting rope, a support frame, a transparent box body arranged on the support frame in a rotary mode by a vertical rotating shaft, a vertical conduit pipe arranged on the support frame, a piston body which can be slidably arranged in the vertical conduit pipe, a lower space-limiting block arranged on the inner side surface of the vertical conduit duct and located below the piston body, a reset spring enabling the piston body to move downwards to reset, a vertical honeycomb duct arranged on the bracing frame and a cleaning honeycomb duct arranged on the bracing frame. A camera device and / or a photographing device are arranged in a transparent box body. One end of the vertical rotating shaft extends into the vertical honeycomb duct, and a driving impeller is arranged on the vertical rotating shaft in the vertical honeycomb duct.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a self-rotating fish protection zone monitoring device. Background technique [0002] Fish spawning grounds are waters where fish and shrimp gather and breed, and are one of the most important physical environmental factors for fish. Most of the spawning grounds of fish and shrimp in the ocean are near the estuaries of large rivers along the coast. For example, the famous Jiangsu Lusi Fishing Ground in China is a spawning ground for large yellow croakers, small yellow croakers, pomfrets, and squids; Zhejiang Zhoushan Fishing Ground is a spawning ground for hairtail, Large yellow croaker, squid and other spawning grounds. [0003] The monitoring of fish spawning grounds is one of the important means to study fish reproduction and reproduction. One of the current monitoring devices for fish spawning grounds is to use camera devices or photographing devices to photograph fish spawning grounds...

AI Technical Summary

Problems solved by technology

At present, the monitoring device of this fish spawning ground that adopts a camera or a camera is usually that the camera or a camera is fixedly installed underwater, and the spawning ground of a certain viewing angle is monitored and photographed by the camera or a camera. Taking pictures, this kind of monitoring device is limited by the angle of view, it is difficult to conduct all-round monitoring, shooting / photographing of fish spawning grounds
