Floating type fish spawning area reserve monitoring device

Abstract

The invention discloses a floating type fish spawning area reserve monitoring device. The floating type fish spawning area reserve monitoring device can effectively increase the monitored area and avoid restriction of visual angles and floating obstacles on water. The floating type fish spawning area reserve monitoring device comprises a main floating frame, a support arranged on the main floatingframe, a monitor arranged on the support, a water pump arranged on the support, a vertical cylinder arranged at the upper opening of the support, a drainage joint arranged on the lower end surface ofthe vertical cylinder, a piston slidingly arranged inside the vertical cylinder, a compressed spring arranged inside the vertical cylinder and under the piston, a plurality of water inlets formed inthe outer surface of the vertical cylinder, a filter mesh tube arranged in a sleeve mode on the vertical cylinder, a cleaning sleeve arranged in a sleeve mode on the vertical cylinder, an upper connecting rod arranged above the vertical cylinder, a first connecting rod connecting the piston and the upper connecting rod, and a second connecting rod connecting the cleaning sleeve and the upper connecting rod.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device for a floating fish spawning ground protection area. 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...

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
