Description

Technical Field

[0001] This utility model relates to the field of salmon farming technology, specifically a three-dimensional multi-layer net cage for salmon farming. Background Technology

[0002] As salmon becomes increasingly popular on dining tables, the demand for salmon farming has been expanding year by year. Salmon primarily refers to Atlantic salmon, which typically needs to be farmed in seawater or brackish water environments. To achieve high-yield, intensive farming, salmon are raised in large, deep-sea cages at high densities in nearshore or offshore areas. This is not only because the seawater environment is closer to natural growing conditions, resulting in superior fish quality, but also because seawater has high dissolved oxygen levels and stable temperatures, making it suitable for high-density farming.

[0003] Most existing aquaculture net cages are circular in design and have a large area, making net retrieval difficult and requiring manual assistance. Furthermore, the circular inner net is prone to tangling in the current, reducing the salmon's living space and increasing maintenance costs. To address these issues, this invention provides a three-dimensional, multi-layered net cage for salmon aquaculture. Utility Model Content

[0025] According to the appendix Figure 1-6As shown, the system includes an outer net body 1 and an inner net body 2. The inner net body 2 includes an inner collection net 21, a left support frame 24, a right support frame 25, and a traction rope 26. The inner collection net 21 is installed inside the outer net body 1 and is used for salmon farming. The left support frame 24 is installed at one end of the inner collection net 21 and includes a sliding lower frame connecting rod 241, which is installed at the bottom of the inner collection net 21. The right support frame 25 is installed at the other end of the inner collection net 21 and includes a large-diameter sliding rod 251. 251 is installed at the bottom of the inner collection net 21. The traction rope 26 is installed at the bottom of the sliding lower frame connecting rod 241 and the large-diameter sliding rod 251 respectively. The traction rope 26 is connected to the power mechanism and is used to pull the inner collection net 21 upward. When it is time to harvest salmon, the motor drives the drum to rotate, which causes the drum to pull the two sets of traction ropes 26 to retract, so that the sliding lower frame connecting rod 241 at the bottom of the left support frame 24 and the large-diameter sliding rod 251 at the bottom of the right support frame 25 both move upward, so that the inner collection net 21 is pulled up upward, which facilitates the harvesting of salmon.

[0026] The inner network body 2 also includes a right sliding support column 23, with a sliding crossbar 232 fixedly connected to the top of the right sliding support column 23. A large-diameter sliding rod 251 is slidably connected to the sliding crossbar 232, and a limit block 233 is fixedly connected to the end of the sliding crossbar 232.
