A cylindrical micro-flow water perch breeding device

Abstract

The application provides a cylindrical micro-flow water perch breeding device. The device solves the problem that the water body is usually in a static state and the perch in the device has poor activity. In use, water circulation is realized through a water inlet pipe at the upper end of the cylinder and a water outlet at the breeding cylinder penetrating the cylinder. Water flowing out of the water outlet pipe impacts on the water surface in the cylinder through multiple water outlet pipes arranged vertically with the water inlet pipe, drives the liquid surface above the cylinder to rotate, and drives the guide ring and the top rod between the inner wall of the cylinder to move upward through the jacking mechanism at the bottom of the cylinder. The top rod is always attached to the lower end surface of the breeding cylinder, the top rod moving upward drives the part of the breeding cylinder bottom in contact with the top rod to deform upward, and drives the water body in the breeding cylinder to move. The continuously circulating movement of the top rod realizes the continuous circulating movement of the water body in the breeding cylinder, and the flowing water body can effectively improve the activity of the perch in the breeding cylinder.
