Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to an aquaculture oxygenation device. Background Technology

[0002] Maintaining sufficient dissolved oxygen in the water is crucial for the healthy growth of aquatic organisms in aquaculture. Therefore, aeration devices are indispensable key equipment in aquaculture. Current aeration devices typically deliver oxygen underwater through pipes and release it into the water as tiny bubbles through a diffuser with fine pores, thereby increasing the dissolved oxygen level. However, this method faces a significant problem over long-term use: the fine pores on the surface of the underwater diffuser are easily clogged by suspended impurities, organic matter, and microorganisms such as algae. Clogged pores severely affect the normal release and diffusion of oxygen, significantly reducing aeration efficiency and failing to effectively increase the dissolved oxygen level. Furthermore, the surface of clogged pores is prone to the growth of harmful bacteria, further deteriorating the water quality and posing a potential threat to the health of aquatic organisms. To restore the aeration effect, the aeration device needs to be cleaned regularly, which usually requires removing the equipment from the water for manual scrubbing or rinsing. This process is tedious, time-consuming, and labor-intensive, increasing the cost and labor intensity of aquaculture management. To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aeration device for aquaculture.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an aquaculture oxygenation device, comprising an air pump, an oxygenation pipe, and an oxygenation cylinder connected to the oxygenation pipe. The top of the oxygenation cylinder is provided with a cylinder cover, and the side walls of the oxygenation cylinder and the cylinder cover are provided with mounting holes. Bolts are threaded into the mounting holes, and the cylinder cover is provided with fine holes.

[0005] The oxygenation pipe is connected to the bottom of the oxygenation cylinder via a vertically installed support pipe, which is used to support the oxygenation cylinder.

[0006] The oxygenation cylinder has a vertically mounted, rotatable drive rod inside, and multiple blades are fixedly connected to the outside of the drive rod.

[0007] The top of the drive rod is fixedly connected to a horizontally arranged brush bar on the cylinder cover, and the bottom side of the brush bar is provided with bristles.

[0008] When the oxygen pump delivers oxygen into the oxygenation cylinder through the oxygenation pipe and the support pipe, the airflow drives the blades and the drive rod to rotate, which in turn drives the brush to rotate, and the brush bristles clean the surface of the cylinder cover.

[0009] Furthermore, a fixing ring is provided inside the oxygenation cylinder, and a fixing rod and a bearing sleeve are provided inside the fixing ring. The drive rod passes through the bearing sleeve and is limited by the fixing rod and the bearing sleeve.

[0010] More specifically, the fixing ring has a fixing hole on its side wall, and a screw passes through the fixing hole to fix it to the inner wall of the oxygenation cylinder.

[0011] Furthermore, a plug is fixedly installed at the top of the drive rod, and a slot that mates with the plug is provided on the bottom side of the brush bar.

[0012] More specifically, the brush strip is threadedly connected to the positioning hole by a screw passing through it.

[0013] Furthermore, a rotating groove is provided in the center of the cylinder cover, and the drive rod passes through the rotating groove.

[0014] Preferably, multiple blades are installed at equal intervals along the outer side of the drive rod.

[0015] Preferably, the fine holes are equidistantly spaced along the top of the cap.

[0016] More specifically, the number of leaves is three.

[0017] Compared with existing technologies, this invention has the following advantages: By setting up a support pipe to connect the oxygenation pipe and the oxygenation cylinder, and using the support pipe to support the oxygenation cylinder, the oxygenation cylinder is effectively prevented from being covered by silt at the bottom of the fishpond, solving the problem of reduced oxygenation efficiency caused by silt cover in existing technologies. Simultaneously, by setting up blades and a drive rod driven by oxygen inside the oxygenation cylinder, the rotation of the blades buffers the incoming air bubbles, preventing large air bubbles from violently moving and causing water flow turbulence, thus solving the problem of large air bubbles disturbing and harming fish in existing technologies. Furthermore, the drive rod drives the brush strips set on the cylinder cover to rotate, and the bristles on the bottom side of the brush strips automatically clean the fine holes on the surface of the cylinder cover, solving the problem in existing technologies where the fine holes are easily clogged by impurities and algae, affecting the oxygenation effect and even breeding harmful bacteria. This device has an ingenious structure, effectively improving the oxygenation effect and equipment maintenance convenience of aquaculture, and reducing the frequency and difficulty of manual cleaning.

Detailed Implementation

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] In aquaculture, oxygenation is crucial for the survival and healthy growth of aquatic organisms. Traditional oxygenation methods often involve directly injecting oxygen into the fishpond through pipes or releasing it through simple diffusers, which easily generates large bubbles, causing water turbulence and disturbing or even harming the fish. Furthermore, the fine pores of underwater aerators, constantly immersed in water, are prone to clogging due to the adhesion and deposition of suspended solids, organic matter, algae, bacteria, and other microorganisms, severely impacting oxygen diffusion and aeration efficiency. Clogged pores not only reduce dissolved oxygen levels but can also breed harmful substances, deteriorating the aquaculture environment. To address these issues, regular cleaning of the aerators is necessary, but existing cleaning methods typically require manual operation, which is cumbersome and inefficient. This invention provides an aquaculture aeration device that, through ingenious structural design, achieves bubble buffering and automatic cleaning of the fine pores, effectively improving aeration efficiency and ease of maintenance.

[0027] like Figures 1 to 6An aeration device for aquaculture is shown, comprising an air pump 1, an aeration pipe 11, and an aeration cylinder 13 connected to the aeration pipe 11. The top of the aeration cylinder 13 is provided with a cylinder cover 21. Mounting holes 23 are provided on the side walls of both the aeration cylinder 13 and the cylinder cover 21. Bolts 35 are threaded into the mounting holes 23. A fine-tuning hole 22 is provided on the cylinder cover 21. The aeration pipe 11 is connected to the bottom of the aeration cylinder 13 via a vertically arranged support pipe 12, which supports the aeration cylinder 13. 3; A rotatable drive rod 14 is vertically installed inside the oxygenation cylinder 13, and multiple blades 2 are fixedly connected to the outside of the drive rod 14; The top of the drive rod 14 is fixedly connected to the brush strip 3 horizontally installed on the cylinder cover 21, and the bottom side of the brush strip 3 is provided with bristles 31; When the oxygen delivered by the air pump 1 enters the oxygenation cylinder 13 through the oxygenation pipe 11 and the support pipe 12, the airflow drives the blades 2 and the drive rod 14 to rotate, which in turn drives the brush strip 3 to rotate, and the bristles 31 clean the surface of the cylinder cover 21.

[0028] Compared with existing technologies, the aeration device of this invention has significant advantages. Existing aeration equipment is easily affected by silt accumulation and blockage of the fine-aperture holes, requiring frequent manual cleaning. This invention, however, effectively avoids the problem of silt accumulation by raising the aeration cylinder 13 through the support pipe 12. More importantly, this invention cleverly utilizes the airflow entering the aeration cylinder 13 as a power source to drive the internal blades 2 and drive rod 14 to rotate, thereby driving the brush strips 3 to automatically clean the fine-aperture holes 22 on the surface of the cylinder cover 21. This automatic cleaning mechanism requires no external power, has a simple and reliable structure, and can effectively remove impurities and algae from the surface of the fine-aperture holes 22, keeping the holes 22 unobstructed and maintaining a high-efficiency aeration effect. Simultaneously, the blades 2 also buffer the air bubbles, reducing disturbance to the water flow and minimizing disturbance to fish.

[0029] When using the aquaculture oxygenation device of this invention, the air pump 1 is started, delivering oxygen or air through the oxygenation pipe 11. The gas enters the bottom of the oxygenation cylinder 13 via the support pipe 12. The gas entering the oxygenation cylinder 13 flows upward, impacting the blades 2 mounted on the drive rod 14, generating driving force and causing the drive rod 14 to rotate around its axis. Since the brush strip 3 is fixedly connected to the top of the drive rod 14, the rotation of the drive rod 14 also causes the brush strip 3 to rotate horizontally above the cylinder cover 21. During the rotation, the bristles 31 on the bottom side of the brush strip 3 continuously sweep across the top surface of the cylinder cover 21, removing impurities, moss, and other dirt deposited around or on the surface of the fine holes 22, preventing the fine holes 22 from becoming clogged. The gas, buffered by the blades 2, continues to rise, being dispersed into tiny bubbles through the fine holes 22 on the cylinder cover 21, and evenly released into the water, achieving efficient oxygenation. Throughout the process, the support pipe 12 always supports the oxygenation cylinder 13, keeping it away from the bottom silt and ensuring unobstructed gas inlet. By employing an airflow-driven automatic cleaning mechanism, this invention effectively solves the technical problems of easy clogging of fine holes, reduced oxygenation efficiency, and inconvenient cleaning and maintenance in the prior art, thereby improving the reliability and practicality of the oxygenation device.

[0030] As one embodiment of this utility model, a fixing ring 15 is provided inside the oxygenation cylinder 13. A fixing rod 17 and a bearing sleeve 18 are provided inside the fixing ring 15. The drive rod 14 passes through the bearing sleeve 18 and is limited by the fixing rod 17 and the bearing sleeve 18.

[0031] In practical implementation, to ensure the stable and smooth rotation of the drive rod 14 inside the aeration cylinder 13, this invention includes a fixing ring 15 within the aeration cylinder 13. The fixing ring 15 is an annular structure with an inner structure for supporting and limiting the drive rod 14, specifically including a fixing rod 17 and a bearing sleeve 18. The drive rod 14 is vertically inserted into the bearing sleeve 18 inside the fixing ring 15; thus, when the gas delivered by the air pump 1 enters the aeration cylinder 13 and drives the blades 2 to rotate, the drive rod 14 can rotate smoothly and reliably under the constraint of this support structure. This stable rotation is crucial for the blades 2 to effectively buffer air bubbles and for the drive rod 14 to accurately drive the brush strips 3 for cleaning. This additional technical feature, by optimizing the rotational support of the drive rod, further improves the working stability and cleaning effect of the entire aeration device.

[0032] As one embodiment of this utility model, a fixing hole 16 is provided on the side wall of the fixing ring 15, and a screw is used to fix and connect it to the inner wall of the oxygenation cylinder 13 through the fixing hole 16.

[0033] In practice, to reliably fix the fixing ring 15 inside the aerator cylinder 13, a fixing hole 16 is provided on the side wall of the fixing ring 15. Simultaneously, a threaded hole is provided at a corresponding position on the inner wall of the aerator cylinder 13. By using a screw, which passes through the fixing hole 16 and connects to the threaded hole, the fixing ring 15 is securely fixed to the inner wall of the aerator cylinder 13.

[0034] As one embodiment of this utility model, a plug 33 is fixedly installed at the top of the drive rod 14, and a slot 32 that cooperates with the plug 33 is opened on the bottom side of the brush strip 3.

[0035] In practical implementation, to achieve a reliable connection between the drive rod 14 and the brush strip 3, so that the rotation of the drive rod 14 can be effectively transmitted to the brush strip 3, a plug block 33 is fixedly installed at the top of the drive rod 14. The plug block 33 is typically a block-shaped structure, and its shape and size match the slot 32 opened on the bottom side of the brush strip 3. The slot 32 is a groove provided on the bottom side of the brush strip 3, and its shape matches the plug block 33, allowing the plug block 33 to be inserted into the slot 32.

[0036] In one embodiment of this utility model, the brush strip 3 is threadedly connected to the positioning hole 34 by a screw passing through the brush strip 3; in order to reliably fix the brush strip 3 to the top of the drive rod 14, it is threadedly connected to the positioning hole 34 by a screw. This means that the positioning hole 34 is a hole with internal threads, which can cooperate with the external threads of the screw.

[0037] As one embodiment of the present utility model, the center of the cylinder cover 21 is provided with a rotating groove 24, and the drive rod 14 passes through the rotating groove 24.

[0038] In one embodiment of this utility model, multiple blades 2 are installed at equal intervals along the outer side of the drive rod 14.

[0039] In one embodiment of this invention, the refining holes 22 are equidistantly spaced along the top of the cap 21; a plurality of refining holes 22 are provided at the top of the cap 21. These refining holes 22 are key structures for the gas to be discharged from the oxygenation cylinder 13 and dispersed into tiny bubbles. In a preferred embodiment, these refining holes 22 are equidistantly spaced along the top surface of the cap 21. This means that the refining holes 22 are uniformly distributed on the top surface of the cap 21, for example, they can be arranged in a concentric circle or grid pattern, and the distance between adjacent holes is approximately equal.

[0040] This equidistant arrangement ensures that when gas is discharged from the cap 21, it is evenly dispersed into the water through the finer holes 22. Uneven distribution of the finer holes 22 would result in some areas having a large gas discharge while others have a small discharge, leading to uneven distribution of dissolved oxygen in the water and affecting the overall oxygenation effect. By using equidistant arrangement, the gas can be evenly fined and released across the entire top surface area of ​​the cap 21, forming a uniformly distributed stream of microbubbles.

[0041] In one embodiment of this utility model, the number of blades 2 is three.

[0042] Working principle of this utility model:

[0043] In use, the air pump 1 is connected to an oxygenation pipe 11 through its outlet. The upper surface of the oxygenation pipe 11, via a vertical support pipe 12, delivers oxygen to the aerator 13 and supports it, preventing it from being covered by silt at the bottom of the fishpond. A fixing ring 15 is secured to the aerator 13 with screws. A fixing rod 17 and a bearing sleeve 18 on the inner side of the fixing ring 15 limit the movement of the vertical drive rod 14. Blades 2 are equidistantly installed on the outer side of the drive rod 14. When oxygen enters the aerator 13, it drives the blades 2 to rotate, providing a buffering effect and preventing large air bubbles from causing water turbulence and affecting fish swimming and feeding. The top of the aerator 13 is detachable. The cylinder has a cover 21 with finer holes 22 evenly spaced at its top. Air bubbles in the aerator 13 are fined through the finer holes 22 and discharged into the fishpond. Workers can remove the bolts 35 inside the mounting holes 23 to replace the cylinder cover 21 with different hole diameters according to usage requirements. The top of the drive rod 14 is fixedly installed with a plug 33, which can be inserted into the slot 32 on the bottom side of the brush strip 3. Then, the brush strip 3 can be horizontally installed on the upper surface of the cylinder cover 21 by screws. When oxygen enters the aerator 13 and drives the blades 2 to rotate, the drive rod 14 can simultaneously drive the brush strip 3 to rotate. The bristles 31 on the bottom side of the brush strip 3 can automatically clean the impurities and moss deposited on the surface of the cylinder cover 21, avoiding clogging of the finer holes 22.
