Fish farming device with salinity auto-control and auto-adjust function of a water body

Abstract

The invention discloses a fish farming device with a salinity auto-control and auto-adjust function of a water body. The main structure comprises a fish tank, a salty water tank, a fresh water tank, an air pump and a central control unit; the central control unit is provided with a fish tank salinity detection probe which reaches to the bottom of the fish tank and is used to detect the salinity of the water body in the fish tank. A strong brine salinity detection probe reaches to the bottom of the salty water tank and is used to detect the salinity of the water body in the salty water tank. The inflow, outflow and quantity of drainage flow of salty water and fresh water in the whole device are regulated and controlled by a flow control implementation structure controlled by the central control unit. The outflow and inflow of the fish tank is controlled by a drainage electromagnetic valve control signal line connected to the outer edge of the bottom of a PVC pipe in the center of the fish tank. By use of the fish farming device, auto-monitor and auto-adjust of the salinity of a water body, and changing water at a same salinity level are achieved. The change of salinity of water body can be preset according to requirements so that the salinity of water body can be changed according to cultivation requirements.

Description

technical field [0001] The invention relates to a fish farming device which can automatically control and adjust the salinity of water body, and belongs to the technical field of fish farming facilities. Background technique [0002] Nowadays, the field of aquaculture is more and more inclined to carry out workshop artificial culture of euryhaline fish and seawater fish, or carry out some saltwater domestication and temporary breeding of traditional freshwater fish. In addition to the traditional seawater cage culture, the regulation of salinity is one of the important factors in the monitoring of water body conditions under artificial culture conditions. For a long time, people have adjusted the salinity by blending seawater with aerated tap water by estimating the volume of the water body, or roughly evaluating the salinity of the water body by dissolving a certain proportion of tap water and sea crystals. Changing the water and cleaning it will definitely cause a sudden ...

Problems solved by technology

For a long time, people have adjusted the salinity by blending seawater with aerated tap water by estimating the volume of the water body, or roughly evaluating the salinity of the water body by dissolving a certain proportion of tap water and sea crystals. Changing the water and cleaning it will definitely cause a sudden change in the salinity of the water body to a large extent, which will cause unfavorable stress responses to the cultured fish, and the re-adjustment of the salinity when changing the water is time-consuming and laborious, and the accuracy is difficult to guarantee

[0003] In addition, many scientific research projects also face the problem of moderate salinity adjustment when conducting experiments on the salinity tolerance of migratory fish and euryhaline fish. Sometimes it is necessary to control the gradient of the water body, or Control the change of the curve in order to better simulate the natural environmental conditions. For a long time, the salinity of the water body has been changed by manual weighing or seawater measurement and calculation, and then blending to control the salinity of the water body , the accuracy is very low, and the error is large

[0004] Therefore, the present invention combines aquaculture with electronic information technology to develop an aquaculture device that can monitor and adjust salinity in real time, so as to solve the difficult problem of accurately controlling the salinity of water bodies
