Description

Technical Field

[0001] This utility model relates to the field of fish farming equipment, and in particular to a fish fry rearing pond with an oxygenation mechanism. Background Technology

[0002] Currently, with the increasing market demand for fish and other aquatic products, the application of high-density intensive farming models in aquaculture is becoming increasingly widespread. However, under high-density farming conditions, the dissolved oxygen concentration in the rearing ponds can easily drop sharply, leading to large-scale mortality of fish fry due to oxygen deficiency, which seriously affects farming efficiency.

[0003] In existing technologies, oxygen is typically supplemented by installing aeration devices in the water tank. However, commonly used aeration devices generally suffer from problems such as limited aeration range and large bubble diameter. Due to the large size of the bubbles, they rise rapidly in the water, resulting in a limited gas-liquid contact area. Consequently, oxygen fails to fully dissolve into the water before quickly escaping to the surface, leading to a low amount of oxygen dissolved in the bubbles and poor oxygenation effect. Utility Model Content

[0018] Please refer to Figures 1-4 This utility model provides a fish fry rearing pond with an oxygenation mechanism, including a rearing pond body 1, a support frame 2 and an oxygenation mechanism 3; The oxygenation mechanism 3 includes a shell 31, an oxygenation device 32, an oxygenation pipe unit 33, a rotating dispersing sleeve 34, and a transmission assembly 35. The oxygenation device 32 and the transmission assembly 35 are respectively disposed in the shell 31. One end of the oxygenation pipe unit 33 is connected to the oxygenation device 32, and the other end of the oxygenation pipe unit 33 passes through the shell 31 and extends into the culture tank body 1. The rotating dispersing sleeve 34 includes an integrally formed sleeve 341 and a rotating disk 342. Both the sleeve 341 and the rotating disk 342 are sleeved on the outer periphery of the oxygenation tube unit 33. The upper end of the sleeve 341 is rotatably assembled to the outer shell 31, and the lower end of the sleeve 341 is connected to the middle of the rotating disk 342. The top surface of the rotating disk 342 has a plurality of air outlet holes 3421 spaced apart. The transmission component 35 is connected to the upper end near the upper end of the sleeve 341 to drive the sleeve 341 and the rotating disk 342 to rotate about the axis of the sleeve 341. The support 2 is mounted on the culture tank body 1, and the outer shell 31 is mounted on the support 2.

[0019] The sleeve 341 and the rotating disk 342 are integrally formed and fit around the outer periphery of the aeration pipe unit 33. The aeration device 32 discharges oxygen to the cultivation tank body 1 through the aeration pipe unit 33, while the transmission component 35 drives the rotating disk 342 to rotate slowly through the sleeve 341. The top surface of the rotating disk 342 has several air outlets 3421 distributed at intervals. The oxygen discharged from the aeration pipe unit 33 enters the water body of the cultivation tank body 1 through the air outlets 3421. As the rotating disk 342 rotates, the position of the air outlets 3421 continuously changes, increasing the aeration range and improving the dissolved oxygen rate.

[0020] The fish fry rearing pond with an oxygenation mechanism is equipped with an oxygenation device 32, an oxygenation pipe unit 33, a rotating dispersing sleeve 34, and a transmission assembly 35. The rotating dispersing sleeve 34 disperses the large air bubbles discharged from the oxygenation pipe unit 33, increasing the diffusion area of ​​the air bubbles. At the same time, it increases the contact area between the air bubbles and the water, improves the dissolved oxygen rate, ensures the oxygen content in the water, avoids fish mortality due to low oxygen content, and improves the survival rate of the fish.

[0021] Specifically, the support 2 is provided with a swing avoidance notch 21, and hinge seats 22 are provided on both sides of the swing avoidance notch 21. The two sides of the outer shell 31 are respectively hinged to the hinge seat 22 on the corresponding side, so that the oxygenation pipe unit 33 and the rotating dispersing sleeve 34 can swing along the length direction of the cultivation tank body 1.

[0022] With the above structure, the outer shell 31 can swing along the length of the rearing tank body 1 through the cooperation of the outer shell 31 and the hinge seat 22, thereby driving the oxygenation pipe unit 33 and the rotating dispersing sleeve 34 to swing along the length of the rearing tank body 1. The oxygenation pipe unit 33 and the rotating dispersing sleeve 34 can be temporarily moved from the bottom area of ​​the rearing tank body 1 to the middle position of the rearing tank body 1, which is convenient for cleaning the bottom of the rearing tank body 1 and catching the fish fry.

[0023] Specifically, the transmission assembly 35 includes a transmission motor 351, a drive gear 352, and a driven gear 353. The transmission motor 351 is disposed in the housing 31, the drive gear 352 is disposed at the drive end of the transmission motor 351, and the driven gear 353 is sleeved on the outer periphery of the sleeve 341. The drive gear 352 and the driven gear 353 mesh.

[0024] The above structure is compact and space-saving, and it also has relatively low operating noise, long lifespan, high reliability, and low maintenance requirements.

[0025] In one specific embodiment of this utility model, the driven gear 353 has more teeth than the driving gear 352, thus forming a reduction gear pair structure to reduce the rotational speed of the rotating and disintegrating sleeve 34.

[0026] Specifically, the oxygenation pipe unit 33 includes an oxygenation main pipe 331 and two or more oxygenation branch pipes 332; the upper end of the oxygenation main pipe 331 is connected to the oxygenation device 32, and the lower end of the oxygenation main pipe 331 is connected to one end of two or more oxygenation branch pipes 332. The oxygenation branch pipes 332 are circumferentially distributed around the axis of the oxygenation main pipe 331, and the oxygenation branch pipes 332 are provided with multiple exhaust holes 333 at intervals along their own length.

[0027] The oxygenation main pipe 331 is used to connect the oxygenation device 32 and the oxygenation branch pipes 332. Several of the oxygenation branch pipes 332 are circumferentially spaced around the axis of the oxygenation main pipe 331, which increases the oxygen supply area and improves the oxygenation effect.

[0028] Optionally, the sidewall of the rotating disk 342 is provided with a plurality of auxiliary air outlets 3422 at intervals.

[0029] The drive motor 351 can drive the rotating disk 342 to rotate through the sleeve 341. When the rotating disk 342 rotates, the oxygen that enters the rotating disk 342 through the oxygenation branch pipe 332 is discharged from the auxiliary air outlet 3422 under the action of centrifugal force, thereby increasing the oxygen supply area.

[0030] Specifically, both the vent 3421 and the auxiliary vent 3422 are equipped with a de-splitting mesh 301, which is horizontally sealed in the vent 3421 or the auxiliary vent 3422.

[0031] With the above structure, when bubbles pass through the dispersing net 301, they are divided into multiple small bubbles by the dispersing net 301, further improving the dissolved oxygen efficiency.

[0032] Preferably, the side wall of the cultivation tank body 1 is provided with an annular branch pipe 11, and a plurality of downwardly inclined water outlet pipes 12 are evenly distributed on the side of the annular branch pipe 11.

[0033] The water is sprayed into the water body of the rearing tank 1 through several evenly distributed downward-sloping water outlets. The water jets with uniform downward force create a uniform and subtle slapping effect with the water body of the rearing tank 1, effectively creating a water surface flow. This not only promotes surface water flow and enhances the flowability of aquaculture water in the rearing tank, but also improves the oxygen dissolution effect in the rearing container.

[0034] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
