Description

Technical Field

[0001] The utility model belongs to the technical field of fish farming equipment, and particularly relates to an oxygenation device for fish ponds. Background Art

[0002] In fish farming, in order to ensure the survival rate of fish, an oxygenation device is needed to increase the oxygen content in the water to ensure that the fish in the water do not lack oxygen. Moreover, oxygen supply can also inhibit the growth of anaerobic bacteria in the water, which is beneficial to the survival of fish.

[0003] Chinese Patent with publication number CN210043003U discloses an oxygenation mechanism for fish ponds, which includes a water pool and an oxygenation pipe extending into the water pool and communicating with an oxygenation machine. In the utility model, a water baffle is arranged above the outlet of the oxygenation pipe in the water pool. By using the vibration of the water baffle, the elastic iron wire and the elastic sheet are driven to vibrate, so that the water above the same plane as the outlet of the oxygenation pipe flows, improving the oxygenation area and efficiency. The structure is simple, the cost is low, and the practicability is strong. However, in the process of use, only the vibration of the water baffle, the elastic iron wire and the elastic sheet makes the water flow, and the flow effect is poor. The water in the water pool cannot fully contact with the air, resulting in limited oxygen supply capacity and a small oxygen supply range, which is not conducive to the survival of fish.

[0004] Chinese Patent with application number CN202322021180.9 discloses an oxygenation device for fish ponds. When several stirring blades rotate, the water in the fish pond is stirred, so that the water in the fish pond fully contacts with the air, increasing the oxygen in the water. And through the mutual cooperation of the oxygenation component and the diffusion component, the oxygen in the water is further increased, expanding the oxygen supply range, which is beneficial to the survival of fish, and solving the problem that the water in the existing technology cannot fully contact with the air, resulting in limited oxygen supply capacity of the water pool.

[0005] With further research by the applicant, it is found that due to the limitation of its own structure, the diffusion component of this technical solution adopts a plate-shaped structure, and part of the air pumped into the diffusion component will accumulate at the bottom of the diffusion plate and cannot be affected by the rotating component arranged above, resulting in a reduction in the oxygen supply range and the oxygen content in the water liquid, which is not more conducive to the survival of fish. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0007] An oxygenation device for fish ponds, comprising:

[0008] A mounting plate;

[0009] A buoyancy component, which is arranged in an array on the outer circumferential surface of the mounting plate;

[0010] The rotating assembly is arranged below the mounting plate, and the rotating assembly has a hollow stirring shaft connected to the mounting plate;

[0011] The diffusion assembly; and

[0012] The oxygenation assembly is arranged on the mounting plate and is used for pumping external air into the stirring shaft and injecting the air into the water in cooperation with the diffusion assembly;

[0013] The diffusion assembly includes at least two groups of air guiding members that are axially distributed along the stirring shaft and connected to form a sector-shaped cross-section. Each group of air guiding members has a first diversion channel communicated with the stirring shaft and several groups of second diversion channels distributed on the conical surface of the air guiding member. Each group of second diversion channels is communicated with the first diversion channel, and several air outlet holes are further arranged on each group of second diversion channels.

[0014] Furthermore, the air outlet holes are distributed on both the inner and outer sides of the conical surface of the air guiding body and are communicated with the second diversion channel.

[0015] Furthermore, the air guiding member is arranged with the opening facing upward.

[0016] Furthermore, there are three groups of the air guiding members.

[0017] Furthermore, the second diversion channel is in a ring shape.

[0018] Furthermore, there are three groups of the second diversion channels.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present diffusion assembly adopts air guiding members with a sector-shaped cross-section, which are sequentially connected to the stirring shaft. The air introduced into the stirring shaft can be dispersed to the second diversion channel through the diversion of the first diversion channel, so that the introduced air is dispersed. The air is discharged from the air outlet holes arranged on the inner and outer walls of the air guiding member, and can be discharged upward to the rotating assembly without hindrance, thereby further increasing the process of oxygen exhausting upward in the water, preventing accumulation, expanding the oxygen supply range, and being more beneficial to the survival of fish.
