Coastal zone fishery conservation area seabed monitoring system

Abstract

The invention discloses a coastal zone fishery conservation area seabed monitoring system, and aims at providing a coastal zone fishery conservation area seabed monitoring system capable of effectively increasing the view angle range of monitoring and shooting / photographing a spawning site by a shooting device or a photographing device of a monitoring device on the premise of not affecting the endurance time of the monitoring device. The monitoring system comprises a buoyancy device, a connecting rope, a supporting frame, a transparent box rotationally arranged on the supporting frame through a vertical rotating shaft, a vertical conduit arranged on the supporting frame, a piston body slidably arranged in the vertical conduit, a lower limiting block arranged on the inner side face of the vertical conduit and located below the piston body, a reset spring enabling the piston body to move downwards to reset, a vertical flow guide pipe arranged on the supporting frame and a cleaning flow guide pipe arranged on the supporting frame, and a shooting device and / or a photographing device are / is arranged in the transparent box. One end of the vertical rotating shaft stretches into the vertical flow guide pipe, and a driving impeller is arranged at the position, located in the vertical flow guide pipe, on the vertical rotating shaft.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a seabed monitoring system for a coastal zone fishery protection zone. 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 s...

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
