Intelligent barrier net aquaculture substrate blow-down system and method

Abstract

The invention relates to an intelligent barrier net aquaculture substrate blow-down system and method, and mainly relates to the field of seawater barrier net aquaculture. The system comprises a system control module, a wireless communication module, a water environment monitoring module, a blow-down treatment module, a position detection module, a terminal module, a barrier net and bottom mud inthe shape of a 'pointed bottom'. The invention further provides the blow-down method based on the system. The method includes the steps: detecting the flow speed and the water level of water; startingthe blow-down treatment module to work, accordingly cleaning sea bottom mud in an area with the barrier net into the shape of the 'pointed bottom', and then discharging dirt to open sea by tidal water flow when tide falls by one-third to two-thirds and the shape of the bottom mud reaches a set upper limit range; stopping work of the blow-down treatment module when the shape of the bottom mud reaches a set lower limit range. By the aid of the 'pointed bottom' shape of the bottom mud, water depth is increased, and pollution and energy consumption are reduced.

Description

technical field [0001] The invention relates to an intelligent seine culture substrate sewage discharge system and method, and mainly relates to the field of seawater seine aquaculture. Background technique [0002] Seine aquaculture in seawater is a model in which fish are raised in captivity in natural water environments such as offshore. In the process of aquaculture, the water quality of aquaculture farms seriously affects the quality and efficiency of aquaculture. Feces, dead matter, sediment, microorganisms, etc. in the water will seriously affect the local water quality in the seine if they are not treated in time. Although seine aquaculture has less restrictions on the scale of aquaculture, the seine aquaculture is limited by the length of the fence and construction technology, and it is often within tens of meters of water depth, even when the tide is low, it is only less than ten meters deep. Due to insufficient water depth, excrement from aquaculture accumulates...

AI Technical Summary

Problems solved by technology

Due to insufficient water depth, aquaculture excrement, etc. accumulate at the bottom of the water, forming a sludge layer, which is likely to cause local water pollution and seriously affect the survival and growth of fish and shrimp.

In addition, the existing conventional treatment method is to use very long sewage pipes to discharge pollutants into the open sea

However, such equipment takes up a lot of space, and the cost is high. Moreover, due to the internal pressure of the sewage pipe, a high-power sewage pump is required, which wastes energy.

In addition, due to the lack of intelligence, it is impossible to view and control the breeding equipment remotely, and manual inspection is time-consuming and labor-intensive, and the response is not timely enough
