Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to an oxygenation detection and control device for aquaculture and a use method thereof. Background Art

[0002] Dissolved oxygen is a very important water quality indicator for fishery water bodies. Dissolved oxygen refers to molecular oxygen dissolved in water, which is an indispensable condition for the survival of aquatic organisms and plants. It has an important impact on water quality and the growth of farmed organisms. Timely grasping the dynamic changes of dissolved oxygen in pond waters and predicting the dissolved oxygen in ponds before the ponds become hypoxic are urgent issues to be solved in aquaculture production. Modern aquaculture usually tests the dissolved oxygen in water bodies.

[0003] When using the existing oxygenation detection and control device for aquaculture, a dissolved oxygen detection sensor is usually placed in the breeding pond to detect the oxygen content inside the breeding pond, and oxygenation is performed according to the detection result to ensure that the oxygen content inside the breeding pond is sufficient to maintain the normal growth of aquatic products.

[0004] However, the existing oxygenation detection and control device for aquaculture and its use method have the following shortcomings: When testing the oxygen content in the breeding pond, the testing depth cannot be flexibly adjusted. Only the oxygen content of water at a single depth can be measured, which requires manual intervention and adjustment, resulting in low actual detection accuracy and poor work efficiency. In addition, since the device itself needs to operate for a long time, its energy consumption cost is high, which is difficult to meet actual usage needs.
