Embodiment Construction

[0011] In order to facilitate the comparison of new and old technical solutions, the present invention attaches image 3 A sectional view of the buoyancy riser of the disclosed existing culture net cage is provided, and the top of the pipe cavity is provided with an inlet and exhaust valve 16, and the attached Figure 4 A sectional view of the disclosed existing buoyancy riser intake and exhaust valve is given. Its working principle is that when the net cage is inflated and drained to float, the gas is filled into the intake and exhaust valve 16 through the intake and exhaust ports 7, and the water in the valve is discharged into the tube cavity 9 through the bottom center through hole 19, and when the floating ball 15 seals Block the central through hole 19, water is pressed into the lumen through the auxiliary through hole 20, the water in the lumen is discharged out of the pipe through the bottom inlet and outlet valve, and finally the bottom inlet and outlet 13 is blocked ...

Abstract

The invention provides a buoyancy vertical pipe of a self-balancing ups and downs cultivation net cage and relates to sea farming equipment. The pipe comprises a middle pipe body 1, a top pipe cap 2, a pipe cap internal-connected ventilation chamber 4 and a bottom flange plate 10; the bottom end of a pipe cavity is provided with a water inlet / drainage valve 12 while the top end is provided with a central air inlet / exhausting opening 7; the inner surface of the top of the pipe cavity 9 is a circular arc shape or a conic shape; and one floating ball 14 is arranged in the pipe cavity. The buoyancy vertical pipe has the advantages that the air inlet / drainage valve at the top end in the pipe cavity of the former buoyancy vertical pipe is removed; one floating ball is arranged in the pipe cavity so that the air inlet / exhausting and water inlet / drainage process is accelerated; and the net cage is steadier to life in a balance manner. The buoyancy vertical pipe is simple in structure and saves manufacturing cost.

Description

Technical field: [0001] The invention relates to seawater aquaculture equipment, and mainly relates to a buoyancy standpipe constituting the frame of an aquaculture net cage. Background technique: [0002] Chinese patent ZL201120298320.1 discloses a self-balancing sinking-floating ecological culture cage, the cage frame includes a circle of multiple buoyancy risers, top connecting pull pipes and bottom connecting pull pipes. The buoyancy standpipe constituting the net cage frame is composed of a middle pipe body, a top pipe cap and an inline ventilation chamber of the pipe cap, a bottom flange connecting plate, an inlet and exhaust valve at the top of the pipe cavity and an inlet and outlet valve at the bottom. The top inlet and exhaust valve is constructed as a hollow tube with a top spool and a bottom plug. The inner surface of the top spool is tapered and concave with a central through hole 1. The bottom plug has a central through hole 2 and a central through hole. A plu...
