Description

Technical Field

[0001] The utility model relates to the technical field of fishery breeding, in particular to a breeding cage. Background Art

[0002] The main structural form of aquaculture cages in my country is generally composed of a cage body, a net and a floating device. The floating device is arranged on the upper part of the cage body to provide buoyancy for the cage body, so that the aquaculture cage floats on the water surface.

[0003] Chinese patent number CN208286198U discloses a fish farming cage comprising a central column, a first ballast tank disposed within the central column, and a first self-flowing water hole and a first connecting hole formed on the central column, both of which are connected to the first ballast tank. Eight side columns arranged in a regular octagon form a frame structure, which is connected to the central column via a connecting mechanism. The tops of adjacent side columns are connected by a first horizontal strut. A central buoy is connected to the bottom of the central column, a second ballast tank disposed within the central buoy, and a second self-flowing water hole and a second connecting hole formed on the central buoy. A first fishing net is attached to the inner surface of the frame structure, and a second fishing net is attached to the outer surface of the frame structure. This fish farming cage features high overall strength, strong wind and wave resistance, a long service life, and adjustable buoyancy.

[0004] By opening a gravity water hole on the surface of the center buoy, although it is convenient for water to enter the center buoy and the water in the center buoy to be discharged from the gravity water hole, a large amount of water flows into the center buoy, and the mud and sand in the water can easily enter the center buoy from the gravity water hole, causing the gravity water hole to be blocked, and ultimately affecting the floating state adjustment of the cage. Utility Model Content

[0005] The purpose of the present invention is to provide a breeding cage to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a breeding cage, comprising a net body, a plurality of first support rods and a plurality of buoyancy rods, the first support rods being fixedly connected to the surface of the buoyancy rods, the net body being fixedly connected to the outer surface of the first support rods, the ends of the buoyancy rods being fixedly connected to expansion floats, the surfaces of the expansion floats being fixedly connected to a center tube, a first reinforcement plate being fixedly connected between two adjacent first support rods, a cross beam being fixedly connected between the first reinforcement plate and the center tube, and the cross beam and the center tube being connected to each other, an exhaust pipe being fixedly connected to the lower surface of the cross beam, an adjustment ring being threadedly connected to the inner wall of the upper end of the center tube, an air inlet pipe being fixedly connected to the upper surface of the adjustment ring, and a one-way valve being provided on the inner side of the adjustment ring.

[0007] Preferably, a plurality of ventilation holes are equidistantly provided on the side of the exhaust pipe.

[0008] Preferably, the surface of the buoyancy rod is fixedly connected to a second support rod, a protective plate is fixedly connected between two adjacent second support rods, a plurality of water holes are opened on the surface of the protective plate, and the bottom of the net body is fixedly connected to the bottom of the protective plate.

[0009] Preferably, a second reinforcement plate is fixedly connected between the two adjacent second support rods, and a serpentine reinforcement plate is fixedly connected between the first reinforcement plate and the second reinforcement plate.

[0010] Preferably, a partition net is detachably installed between the first support rod and the central tube.

[0011] Preferably, a fish inlet pipe is fixedly connected to the surface of the protective plate, and the end of the fish inlet pipe passes through the protective plate. The inner wall of the fish inlet pipe is fixedly connected to a plurality of elastic fish limiting plates in an annular array.

[0012] Preferably, the angle between the elastic fish limiting plate and the central axis of the fish inlet pipe is 30° to 45°.

[0013] The utility model provides a breeding cage with the following beneficial effects:

[0014] 1. The aquaculture cage can inflate the expansion float by connecting the compressed air machine to the upper end of the air inlet pipe, so that the entire aquaculture cage floats, or the adjustment ring can be driven to rotate by rotating the air inlet pipe. By rotating the adjustment ring above the crossbeam tube, under the action of water pressure, the air in the expansion float will be discharged from the central tube through the crossbeam tube and out of the exhaust pipe, so that the entire aquaculture cage can sink. Compared with the existing technology, the present application does not set a self-retaining hole for water injection and drainage to achieve lifting and lowering, and the mud and sand in the water will not enter the central tube. Only a small amount of water flows into the exhaust pipe, so it is not easy to be blocked, thereby providing convenience for the floating adjustment of the cage.

[0015] 2. The aquaculture cage is equipped with a fish inlet pipe and an elastic fish limit plate. During the process of using the cage to culture fish and shrimp, there is a certain probability that wild fish in the water body will enter through the fish inlet pipe, thereby trapping them between the net body and the protective plate. The elastic fish limit plate can effectively prevent the fish from escaping, thereby increasing the yield of fish and shrimp. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1-3 The utility model provides a technical solution: a breeding cage, comprising a net body 1, a plurality of first support rods 2 and a plurality of buoyancy rods 3, the first support rods 2 are fixedly connected to the surface of the buoyancy rods 3, the net body 1 is fixedly connected to the outer surface of the first support rods 2, the end of the buoyancy rod 3 is fixedly connected with an expansion float 4, the surface of the expansion float 4 is fixedly connected with a center tube 5, a first reinforcement plate 6 is fixedly connected between two adjacent first support rods 2, a cross beam tube 7 is fixedly connected between the first reinforcement plate 6 and the center tube 5, and the cross beam tube 7 and the center tube 5 are connected to each other, the lower surface of the cross beam tube 7 is fixedly connected with an exhaust pipe 8, the inner wall of the upper end of the center tube 5 is threadedly connected with an adjusting ring 9, the upper surface of the adjusting ring 9 is fixedly connected with an air intake pipe 10, and a one-way valve 11 is provided on the inner side of the adjusting ring 9.

[0023] By connecting the compressed air machine to the upper end of the air inlet pipe 10 and then inflating the air inlet pipe 10, the one-way valve 11 can be used to prevent air backflow, so that the expansion float 4 can be inflated to make the entire breeding cage float up, or the adjustment ring 9 can be driven to rotate by rotating the air inlet pipe 10. By rotating the adjustment ring 9 to the top of the crossbeam tube 7, under the action of water pressure, the air in the expansion float 4 will be discharged from the central tube 5 through the crossbeam tube 7 and out of the exhaust pipe 8, so that the entire breeding cage can sink. Compared with the existing technology, this application does not set a self-retaining hole for water injection and drainage to achieve lifting and lowering, and the mud and sand in the water will not enter the central tube. Only a small amount of water flows into the exhaust pipe 8, so it is not easy to be blocked, thereby providing convenience for the floating adjustment of the cage.

[0024] The side of the exhaust pipe 8 is provided with multiple vents at equal intervals. Exhaust is discharged through the lower end of the exhaust pipe 8 and the vents, which can effectively increase the oxygen content of the water body and is also beneficial to the survival of fish and shrimp. Of course, in actual application, the multiple vents of the exhaust pipe 8 can be covered with a mesh tube to prevent clogging by external impurities.

[0025] The surfaces of the buoyancy rods 3 are fixedly connected with second support rods 12 , and a protective plate 13 is fixedly connected between two adjacent second support rods 12 . The surface of the protective plate 13 is provided with a plurality of water flow holes.

[0026] By providing the second support rod 12 , the protection plate 13 and the water flow hole, the protection plate 13 can effectively prevent debris in the water flow from damaging the net body 1 .

[0027] The bottom of the net body 1 is fixedly connected to the bottom of the protective plate 13 .

[0028] A second reinforcement plate 14 is fixedly connected between two adjacent second support rods 12 , and a serpentine reinforcement plate 15 is fixedly connected between the first reinforcement plate 6 and the second reinforcement plate 14 .

[0029] By arranging the first support rod 2, the second support rod 12, the first reinforcement plate 6, the second reinforcement plate 14, the serpentine reinforcement plate 15, the central tube 5 and the crossbeam tube 7, the structural strength of the entire cage can be effectively improved and its wind and wave resistance can be improved.

[0030] A partition net 16 is detachably installed between the first support rod 2 and the central tube 5. By setting the partition net 16, the interior of the net body 1 can be divided into multiple areas, thereby realizing regional farming.

[0032] The number of the elastic fish limiting plates 18 is 3 or 4, and the angle between the elastic fish limiting plates 18 and the central axis of the fish inlet pipe 17 is 30 degrees to 45 degrees.

[0033] By setting the fish inlet pipe 17 and the elastic fish limiting plate 18, when using the cage to cultivate fish and shrimp, there is a certain probability that wild fish in the water body will enter through the fish inlet pipe 17, thereby trapping them between the net body 1 and the protective plate 13. The elastic fish limiting plate 18 can effectively prevent the fish from escaping, thereby increasing the fish and shrimp production.

[0034] The drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention. Other structures may refer to conventional designs. In the absence of conflicts, the same embodiment and different embodiments of the present invention may be combined with each other.
