Abstract
Description
Technical Field
[0001] This utility model relates to the field of salmon farming technology, specifically to a water flow regulation device for salmon farming areas. Background Technology
[0002] Salmon, as a high-value aquaculture species, requires large nets in open waters for deep-sea farming to protect it from marine environmental impacts and maintain population density. However, the complex current conditions in the deep sea can cause traditional fixed nets to be subjected to irregular currents, while the currents in shallow waters are too static, leading to uneven distribution of stocking density, poor water exchange, uneven dissolved oxygen distribution, and poor fish health. Therefore, flow regulation devices have become a core supporting technology for deep-sea aquaculture nets, used to dynamically regulate the water flow environment around the nets.
[0003] Existing water flow regulation devices are generally installed on the net cover, agitating the water inside the net to exchange water flow between the inside and outside, thereby increasing water quality and dissolved oxygen levels. Fish waste and uneaten food are then carried out of the net by the current. However, this method can easily cause stress to the fish due to the agitated airflow. Furthermore, a large number of water flow regulation devices are needed to cover the net in all directions to ensure uniform water quality within the net, thus increasing costs. To address these issues, this invention provides a water flow regulation device for salmon farming areas. Utility Model Content

A propeller 233 is rotatably connected inside the airflow component 23. The propeller 233 is used to diffuse the water flow inside the net cage outwards. In use, the propeller 233 rotates, causing the water flow to flow outwards. At this time, the drive connector 22 on the top water surface drives the airflow component 23 to rotate around the outer ring 1, allowing one set of airflow components 23 to regulate the water flow of the entire net cage.
[0025] The connecting component 21 includes a connecting rotating frame 211, a rotating shaft 213, and a rotating roller 212.
