Problems solved by technology

When a typhoon occurs, due to the huge wind and waves, the cages are damaged and a large number of fish in the cages escape, causing huge losses to farmers, thus restricting the development of cage culture
In order to prevent damage to the cage, when the wind and waves are strong, water is often injected into the buoys of the cages manually to make them submerged in the water. During water injection, the cages are often tilted and easily damaged due to the different water inlet speeds of the buoys.
At present, there is no deep-water cage control system that can automatically detect wind and waves, automatically control the net cage to dive when the wind and wave reach a certain intensity, and automatically adjust the water injection speed of the buoy during the dive so that the net cage does not tilt during the dive.

Embodiment Construction

[0018] The invention includes a single chip microcomputer 1, a wind wave sensor composed of eight mercury switches 2, four net cage pontoons and water inlet valve components 3, and a cage 4; among them:

[0019] 1. Microcontroller 1 (such as figure 1 Shown):

[0020] Any type of single-chip microcomputer can be used. Set its eight I / O ports as the wave detection input ports and connect to the corresponding numbered mercury switch output ports in the wind wave sensor, and set the other four I / O ports as the inlet valve control output ports. Then connect with the control ends of the net cage pontoon inlet valves corresponding to the numbers in the four directions;

[0021] 2. Wind wave sensor 2 (such as image 3 , Figure 4 , Figure 5 , Figure 6 Shown):

[0022] The wind wave sensor 2 includes: a positioning gasket 2.1, which is in the shape of a round body, which is gradually recessed from the edge of the round body to the center at an angle of 30°. There is a mounting hole 2.2 i...

Abstract

A control system of profundal netted case for detecting wind and wave and automatic sinking is composed of a single-chip computer, wind and wave sensor consisting of 8 Hg switches, 4 buoys with water inlet valve and netted case.

Description

Technical field [0001] The invention relates to fish farming, and is a deep-water net cage wind wave detection and automatic diving control system. Background technique [0002] Deep water cage is a kind of equipment used for fish culture in cage, and it is a kind of intensive breeding equipment. When a typhoon occurs, due to the huge wind and waves, the cages are damaged and a large number of fish in the cages escape, causing huge losses to farmers, thus restricting the development of cage aquaculture. In order to prevent damage to the cages, manual water injection into the cage pontoons is often used to make them submerged in the water when the wind and waves are heavy. When the water is injected, the cages are often tilted and easily damaged due to the different water inlet speeds of the pontoons. At present, there is no deep-water cage control system that can automatically detect wind and waves, can automatically control the diving of the cage when the wind and waves reach a ...
