Self-rotating fish protection area monitoring device

Abstract

The invention discloses a self-rotating fish protection area monitoring device, aiming to provide a monitoring device capable of effectively increasing the camera device or photographing device of the monitoring device to monitor the spawning ground without affecting the battery life of the monitoring device. A self-rotating fish protection area monitoring device for monitoring the viewing angle range of shooting / photographing. It includes a buoyancy device, a connecting rope, a support frame, a transparent box body rotatably arranged on the support frame through a vertical shaft, a vertical conduit arranged on the support frame, a piston body slidably arranged in the vertical conduit, a set The lower limit block on the inner side of the vertical conduit and below the piston body, the return spring that can make the piston body move down and reset, the vertical flow guide pipe arranged on the support frame and the cleaning flow guide arranged on the support frame tube, and a camera and / or photographing device are arranged in the transparent box. One end of the vertical rotating shaft extends into the vertical guide tube, and a drive impeller is arranged on the vertical rotating shaft and inside the vertical guide tube.

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
