Description

Technical Field

[0001] The invention relates to the technical field of marine aquaculture, in particular to an aquaculture cage with an ocean current utilization device. Background Art

[0002] Marine fisheries have now shifted from fishing to aquaculture, and aquaculture areas have gradually transitioned from land to sea. Seawater cages are one of the important means of aquaculture activities, and there are mainly two types of cages: ordinary cages and deep-water cages. In view of the wind and wave resistance of deep-water cages, most cage frames are now fixed with wood and anchor ropes.

[0003] At present, seawater cages are easily damaged by wind, waves and currents, which can cause the death or escape of fish. In addition, a large amount of energy is wasted when wind, waves and currents hit the cages, resulting in a waste of resources.

[0004] Moreover, the existing aquaculture cages are fed manually or by machines. However, during the aquaculture process, the feed in most cages easily falls to the bottom of the cages and is not fully eaten by the fish, resulting in waste, which can reach up to one third.

[0005] Based on the above content, a breeding cage with a current utilization device is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a breeding cage with a current utilization device. By arranging a turbine on the outside of the breeding cage, the wave current energy is converted into electrical energy for use in the breeding cage, and the problem of damage to the cage caused by the impact of ocean wave current is effectively solved. At the same time, a fish food collection device is arranged at the bottom of the breeding cage, and an electric fish food suspension machine is used to impact the fish food at the bottom for fish to eat, thereby reducing the waste of fish food.

[0007] To achieve the above-mentioned purpose, the present invention provides a kind of aquaculture cage with a current utilization device, comprising aquaculture cage and current utilization units respectively arranged around the aquaculture cage, the current utilization unit comprising a water baffle and a water turbine embedded in the water baffle, the outer upper end of the aquaculture cage is connected with a fixed cross bar, the interior of the fixed cross bar is provided with a rotating shaft, the two ends of the rotating shaft are connected with the water baffle, the rotating shaft is provided with a rotating device, and the aquaculture cage is provided with a fish feeding device and a fish food collecting device.

[0008] Preferably, a shaft seat is provided on the left side of the middle part of the rotating shaft, and a first gear meshing with the rotating shaft is provided on the right side of the rotating shaft, and the first gear is connected to the rotating device.

[0009] Preferably, the rotating device comprises a second gear meshing with the outside of the first gear, a screw rod meshing at the tooth core of the second gear, and the screw rod extends out of the outer end of the fixed cross bar and is connected to the knob.

[0010] Preferably, a turbine line is arranged inside the water baffle, and slots for the turbine line to pass through are arranged inside the fixed cross bar and on the side wall of the breeding cage.

[0011] Preferably, the bottom of the breeding cage is set as a fine mesh bottom surface, a protective cage is arranged at the center of the bottom of the breeding cage, and the top wall and side walls of the protective cage are both set as alloy protective nets.

[0012] Preferably, the bottom of the breeding cage is connected to a fish food collecting trough, the fish food collecting trough is configured as a funnel-like structure, and the side wall of the fish food collecting trough is provided with a fine mesh structure.

[0013] Preferably, the fish food collecting device is arranged at the bottom center of the fish food collecting trough, and the fish food collecting device is configured as a spiral feeding rod and a spiral feeding paddle, and the lower end of the spiral feeding rod extends out of the fish food collecting trough and is connected to the rotating motor.

[0014] Preferably, the upper end of the spiral feeding rod penetrates into the breeding cage and is fixed on the top wall of the protection cage, and an electric fish food suspension machine is provided at the bottom position on both sides of the spiral feeding rod inside the protection cage.

[0015] Preferably, a buoyancy plate is connected to the lower end of the water retaining plate.

[0016] Preferably, the water turbine is connected to the fish food feeding device, the electric fish food suspension machine at the bottom, and the rotating motor respectively through a water turbine line.

[0017] Therefore, the present invention provides a breeding cage with a current utilization device, wherein a water baffle is arranged outside the breeding cage, a water turbine is embedded in the water baffle, a rotating shaft is arranged at the connection between the water baffle and the breeding cage, and the angle of the water turbine on the water baffle is adjusted by a rotating device; when the water turbine is working, when the water flows through the blades of the runner, each blade obtains a certain driving force, thereby driving the runner to rotate, and the other side of the runner is connected to the generator, which can drive the generator to generate electricity. This arrangement can utilize the wave energy to convert into electrical energy, and is connected to various devices through the turbine line to achieve the normal operation of the equipment in the breeding cage; this arrangement not only provides energy for the entire breeding cage, but also water baffles and water turbines are arranged around the breeding cage, which plays a certain protective role on the breeding cage, and effectively solves the problem of damage caused by the impact of ocean wave currents on the cage;

[0018] In addition, the present invention also provides a fish food collecting device at the bottom of the breeding net cage. By providing a fine mesh bottom surface at the bottom of the breeding net cage, the uneaten fish food enters the fish food collecting trough, and is collected in the middle of the bottom by utilizing the funnel-like structure of the fish food collecting trough. At the same time, because the side wall of the fish food collecting trough is provided with a fine screen structure, fine sand, solid waste and other materials can be filtered out. The fish food collected in the middle of the bottom is driven by the spiral feeding rod and the spiral feeding paddle to move upward into the protective box, and is impacted by the electric fish food suspension machine for the fish to eat, thereby reducing the waste of fish food.
