Bottom-sinking type spawning site monitoring device

Abstract

The invention discloses a bottom-sinking type spawning site monitoring device, and aims to provide a bottom-sinking type spawning site monitoring device which can effectively increase the monitoring area of a monitoring device and is not limited by the visual angle of the monitoring device and obstacles in water. The device comprises a base, a bracket arranged on the base, a monitor arranged on the bracket, a water pump arranged on the bracket, a vertical cylinder block arranged on the bracket and provided with an opening in the upper end, a drainage joint arranged on the lower end surface ofthe vertical cylinder block, a connecting pipe connected with the drainage joint and an inlet of the water pump, a piston body slidingly arranged in the vertical cylinder block, a plurality of water inlets formed in the outer side face of the vertical cylinder block, a filter screen cylinder sleeving the vertical cylinder block, a cleaning sleeve sleeving the vertical cylinder block, an upwards floating frame located above the vertical cylinder block, a first connecting rod for connecting the piston body with the upwards floating frame, and a second connecting rod for connecting the cleaning sleeve with the upwards floating frame.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a bottom-sinking spawning ground 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 und...

AI Technical Summary

Problems solved by technology

At present, the monitoring device of this 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. The device is limited by the viewing angle, light and obstacles, so that the monitoring area of ​​the monitoring device is greatly limited, and often only a small area can be monitored
