Water flow-driven rotary fixed-point underwater monitoring apparatus

Abstract

The present invention discloses a water flow-driven rotary fixed-point underwater monitoring apparatus. With the monitoring apparatus provided by the invention adopted, the visual angle range of monitoring image pickup/photographing of an image pickup device or photographing device of the monitoring apparatus can be greatly increased with the time of endurance of the monitoring apparatus not affected. The monitoring apparatus comprises a floating device, a connecting rope, a base, a supporting frame, a transparent box body rotationally arranged on the supporting frame by a vertical rotation shaft, a vertical guiding pipe arranged on the supporting frame, a piston body slidably arranged in the vertical guiding pipe, a lower limiting block which is arranged at the inner side surface of the vertical guiding pipe and is located below the piston body, a return spring which can make the piston body move downwardly to make the piston body reset, a vertical flow guiding pipe arranged on the supporting frame, and a cleaning flow guiding pipe arranged on the supporting frame; an image pickup device and/or a photographing device is arranged in the transparent box body; one end of the vertical rotation shaft extends into the vertical flow guiding pipe; and the vertical rotation shaft is provided with a driving impeller located in the vertical flow guiding pipe.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a water flow-driven rotary fixed-point underwater 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 spa...

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
