Abstract

The invention belongs to the technical field of net cage culture, and relates to a culture net cage capable of automatically supplying oxygen and changing water. The device comprises a culture net cage, wherein the culture net cage comprises an upper supporting floating frame and a lower supporting frame, a plurality of bait recovery cylinders are arranged between the upper supporting floating frame and the lower supporting frame, and an anchor is connected to each bait recovery cylinder through a rod; upper pistons are arranged in the bait recovery cylinders; piston rods are coaxially fixed to the upper pistons, the upper ends of the piston rods extend out of the bait recovery cylinders and the end parts are connected with the upper supporting floating frame; an air inlet pipe is arrangedon one of the bait recovery cylinder and air exhaust pipes are arranged on the bait recovery cylinders; one end of the air inlet pipe and one end of the air exhaust pipes both extend into a chamber partitioned by each the upper piston into each the bait recovery cylinder; the other end of the air inlet pipe extends out of the sea surface and an air inlet one-way valve is fixed to the end part; and the other end of each the exhaust pipe extends into the culture net cage and an air exhaust one-way valve is arranged at each the end part. The device has the advantages of realizing automatic oxygen supply and water exchange of the culture net cage.

Description

Technical field

[0001] The invention belongs to the technical field of cage culture, and relates to a culture cage with automatic oxygen supply and water change. Background technique

[0002] Due to the advantages of low cost, high yield, convenient management and high recovery rate, cage aquaculture has developed rapidly in coastal areas in recent years.

[0003] One type of culture cage is mainly composed of a ring-shaped support floating frame, a culture cage and a fixing device. Among them, the ring-shaped support floating frame floats on the sea; the upper end of the culture cage is open, and the edge of the upper end of the culture cage is fixed on the ring float. On the rack, the gravity of the aquaculture cage is used to lower the bottom of the aquaculture cage to a defined depth under the water; the fixing device includes a number of counterweights that settle to the bottom of the sea and a fixed cable connecting the counterweight and the annular support floating frame for...

Examples

Embodiment 1

[0037] Reference Figure 1 to Figure 5 , A culture cage with automatic oxygen supply and water exchange, comprising a culture cage 1 floating in the sea, the culture cage 1 comprising an upper supporting floating frame and a lower supporting frame, and further comprising:

[0038] A number of cylindrical bait recovery cylinders 3, each of the bait recovery cylinders 3 is vertically arranged and slidably connected between the upper support floating frame and the lower support frame, and each bait recovery cylinder 3 passes through one An anchor 23 is connected to the rod; an upper piston 31 is coaxially arranged and slidingly connected to the bait recovery cylinder 3; a piston rod 311 is fixed coaxially on the upper piston 31, and the upper end of the piston rod 311 extends out of the bait recovery cylinder 3 and the end is connected with the upper supporting float; the bait recovery cylinder 3 is provided with an intake pipe 351 and an exhaust pipe 353; both ends of the intake pip...

Embodiment 2

[0077] The technical solution of this embodiment is basically the same as that of the first embodiment, and the difference lies in:

[0078] Reference Image 6 with Figure 7 Specifically, a ring frame is slidably arranged around the culture cage 1, and the ring frame is fixedly connected to the anchor 23 by a rod; the ring frame includes two coaxially arranged and fixedly connected fixed rings 2; each The fixed rings 2 are all fixedly connected with the bait recovery barrel 3.

[0079] When the aquaculture cage 1 floats up and down, the two fixed rings 2 and several bait recovery cylinders 3 are fixed by anchors 23 so as to remain stationary relative to the aquaculture cage 1, and each of the sliding sleeves 21 is on its own column 12 Sliding up and down, so as to realize that the aquaculture cage uses tidal energy and wave energy as energy to automatically supply oxygen, change water, and automatically recover bait and reuse.

[0080] The arrangement of the two fixed rings 2 effec...
