A 360-degree rotation monitoring spawning ground monitoring equipment

Abstract

The invention discloses a spawning field monitoring device for 360-degree rotation monitoring, aiming to provide a monitoring device that can effectively increase the impact of the monitoring device's camera or photographing device on the spawning field without affecting the battery life of the monitoring device. A monitoring device that monitors the range of viewing angles for 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. A driving impeller is arranged on the vertical rotating shaft and inside the vertical guide tube. The bottom of the supporting frame is provided with several supporting feet.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a spawning ground monitoring device suitable for 360-degree rotation monitoring of fish spawning grounds. 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 equipment for fish spawning grounds is to use camera devices or photo...

AI Technical Summary

Problems solved by technology

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