Wave energy utilizing marine conservation area monitor

Abstract

The invention discloses a wave energy utilizing marine conservation area monitor, and aims at providing a monitor being able to effectively increase the spawning ground monitoring video shooting / picture shooting visual angle range of the video shooting device or the picture shooting device of the monitor without influencing the endurance time of the monitor. The monitor comprises a buoyant device, a connecting rope, a pedestal, a supporting rack positioned above the pedestal, a transparent box body arranged on the supporting rack in rotatable manner through a vertical rotating shaft, a vertical guiding tube arranged on the supporting rack, a piston body arranged in the vertical guiding tube in a slidable manner, a lower limiting block arranged on the inner side surface of the vertical guiding tube and positioned under the piston body, a reset spring for realizing downward movement reset of the piston body, a vertical flow guiding tube arranged on the supporting rack, and a cleaning flow guiding tube arranged on the supporting rack, and a video shooting device and / or a picture shooting device is arranged in the transparent box body. Driving impellers are arranged on a vertical rotating shaft and positioned in the vertical flow guiding tube. The bottom of the supporting rack is provided with a plurality of downward extending supporting legs.

Description

technical field [0001] The invention relates to a monitor, in particular to a monitor for a marine protection area utilizing wave energy. 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 monitors for fish spawning grounds is to use camera devices or photographing devices to photograph fish spawning grounds underwater. ...

AI Technical Summary

Problems solved by technology

At present, the monitor of the fish spawning ground that adopts a camera device or a camera device is usually that the camera device or camera device is fixedly installed underwater, and the spawning ground of a certain angle of view is monitored and photographed by the camera device or camera device. Taking pictures, this kind of monitor is limited by the angle of view and it is difficult to monitor, shoot / photograph the fish spawning ground in all directions
