Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a recirculating aquaculture tank for promoting the growth of mandarin fish. Background Technology

[0002] In the process of raising mandarin fish, circulating water allows the fish to "run," which increases their exercise. Raceway fish farming utilizes water flow to stimulate fish movement and improve meat quality, and is one of the core measures in mandarin fish farming.

[0003] When the water flow generator is placed in the upper-middle layer (30% depth), the resulting water flow may not effectively stimulate the fish. When the generator is placed at 60% depth, the activity of the mandarin fish against the current increases by 40% (compared to the surface setting). However, for juvenile fish, the depth should be adjusted to 40% to avoid strong current impact. According to the living habits of mandarin fish, they are usually active in deeper layers at night and more active in shallower layers during the day. Traditional water flow generators have fixed installation positions and cannot be adjusted according to the living habits of mandarin fish. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a recirculating aquaculture tank for promoting the growth of mandarin fish, thus providing a more precise solution to the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a recirculating aquaculture tank for promoting the growth of mandarin fish, including a culture tank.

A vertically arranged sliding shaft and lead screw are connected between the top of the lifting bracket and the bottom of the culture tank. A water flow generating plate is connected to the sliding shaft and lead screw. A valve core is fitted in the middle of the water flow generating plate. One end of the valve core is connected to a water pipe connector. A shallow water outlet is provided above one side of the water flow generating plate, and a deep water outlet is provided below the shallow water outlet.

[0007] Furthermore, the back of the water flow generating plate is provided with a pair of connecting seats, and the pair of connecting seats of the water flow generating plate are respectively connected to the sliding shaft and the lead screw. The top of the lifting bracket is provided with a first motor, and the output shaft end of the first motor is connected to the upper end of the lead screw for transmission.

[0008] Furthermore, the valve core is a circular tube that is rotatably connected to the middle of the water flow generating plate, and the side wall of the valve core is provided with a flow exchange slot that communicates with the inner cavity of the water flow generating plate.

[0009] Furthermore, a worm gear is provided at the end of the valve core away from the water pipe joint, and a pair of worm supports are provided on the side wall of the water flow generating plate near the worm gear. A vertically arranged worm is rotatably connected between the pair of worm supports, and the worm is engaged with the worm gear in a transmission.
