Description

Technical Field

[0001] This utility model belongs to the field of freshwater aquaculture oxygen supply technology, and specifically relates to a multi-point oxygen supply device for freshwater aquaculture. Background Technology

[0002] Currently, the freshwater aquaculture industry generally uses multi-point oxygen supply devices to meet the oxygen demand of large-scale aquaculture. These devices typically consist of a main oxygen supply pipe and multiple branch pipes. The branch pipes are arranged at equal intervals and aeration heads are installed in the water. The main oxygen supply pipe supplies oxygen through an external air source (such as an aerator) and diffuses it to various parts of the aquaculture pond through the branch pipes. Most existing oxygen supply devices use metal or PVC pipes. The branch pipes are mainly connected and fixed to the main pipe by threads or flanges. Aeration methods include micropore aeration and jet aeration to improve the oxygen dissolution efficiency in the water.

[0003] However, the above-mentioned oxygen supply devices have obvious shortcomings in practical applications: First, the threaded connections are prone to corrosion due to long-term contact with water, making it inconvenient to disassemble and repair the joints. During maintenance, each branch pipe needs to be disassembled, which is cumbersome and makes it difficult to quickly restore oxygen supply. These problems not only increase maintenance costs, but may also affect the growth of aquatic organisms due to insufficient oxygen supply, thus restricting the improvement of aquaculture efficiency. Second, the pipe ends lack effective protection, and impurities such as mud, sand, and algae can easily clog the aeration holes, seriously affecting the oxygen supply effect. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a multi-point oxygen supply device for freshwater aquaculture, so as to solve the problem of cumbersome disassembly and maintenance during the application of the existing technology.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A multi-point oxygen supply device for freshwater aquaculture includes oxygen pipelines. An installation mechanism is fixedly installed on one side of the oxygen pipelines in a linear arrangement at equal intervals. An oxygen supply component is installed on the oxygen pipelines through the installation mechanism. An oxygen supply hose is fixedly installed on one side of the oxygen pipelines, and an oxygen supply pump is fixedly connected to the outer end of the oxygen supply hose.

[0007] The installation mechanism includes a regulating valve, an outer connecting pipe fixedly connected to the outer end of the regulating valve, the regulating valves being linearly arranged at equal intervals and fixedly installed on one side of the oxygen pipeline, the inner side of the outer connecting pipe being connected to the oxygen pipeline, a sleeve fitting being fitted on the outer side of the outer connecting pipe, a snap-fit ​​assembly being fixedly connected to the top of the outer connecting pipe, the oxygen supply assembly being fixedly connected to the outer side of the sleeve fitting, and slots being provided on both sides of the sleeve fitting, the end of the snap-fit ​​assembly being inserted into the slot.

[0008] Furthermore, the snap-fit ​​assembly includes a top rail, which is fixedly connected to the top of the outer tube. Both ends of the top rail are fixedly connected to limit springs. A slider is fixedly connected to the end of the limit spring. A connecting arm is fixedly connected to the top of the slider. A limit block is fixedly connected to the inner side of the outer end of the connecting arm. The end of the limit block is inserted into the inside of the slot. An adjustment group is provided on the top of the top rail.

[0009] Furthermore, the adjustment assembly includes a push block and an adjustment guide rail. The adjustment guide rail is fixedly connected to the top center of the top rail, and the push block is fixedly connected to the top of the connecting arm. Limiting springs are fixedly connected to both ends of the adjustment guide rail. A movable block is fixedly connected to the end of the limiting spring. A guide frame is fixedly connected to the top of the movable block. The guide frame and the push block are connected in a transmission manner. The end of the guide frame near the connecting arm is generally arranged in an isosceles trapezoidal shape, and the inclined surface of the guide frame is in close contact with the surface of the push block.

[0010] Furthermore, an adjustment plate is fixedly connected to the top of the guide frame on the side away from the oxygen supply component, and the upper end of the adjustment plate is generally circular.

[0011] Furthermore, the oxygen supply assembly includes a connecting hose, which is fixedly connected to the outside of the socket. A mounting base is fixedly connected to the outer end of the connecting hose, and an oxygen exhaust pipe is fixedly connected inside the mounting base. Aeration nozzles are fixedly connected to the outer surface of the oxygen exhaust pipe in a ring at equal intervals.

[0012] Furthermore, a protective mesh cover is inserted on the outside of the oxygen exhaust pipe on the mounting base. The protective mesh cover is fitted over the outside of the oxygen exhaust pipe and the aeration nozzle. Both ends of the mounting base are threaded with mounting screws, and the protective mesh cover is installed on the mounting base through the mounting screws.

[0013] Furthermore, a helical anchor rod is fixedly connected to the bottom of the mounting screw, and the mounting screw is configured as a hand-tightening screw.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model can improve the efficiency of disassembly, assembly, and maintenance of oxygen supply components by setting up an installation mechanism. During installation, the limit spring pushes the slider, connecting arm, and limit block to move. Through the engagement of the limit block with the slot of the outer pipe, the sleeve joint and the outer pipe are quickly fixed, thereby completing the connection between the oxygen supply component and the regulating valve. During maintenance, the corresponding regulating valve can be adjusted to close the faulty pipeline without affecting the normal oxygen supply of other components. At the same time, the guide frame and movable block are driven by the adjusting plate to squeeze the pushing block and open the connecting arm so that the limit block is disengaged from the slot, which can quickly disassemble the sleeve joint, reduce maintenance time, ensure the stable operation of the oxygen supply system, and reduce maintenance costs.

[0016] Secondly, the oxygen supply mechanism of this device achieves efficient oxygenation of the water body through automated fluid transmission. During use, after the oxygen supply pump is started, oxygen is released into the water body through the external pipe, sleeve, connecting hose and oxygen discharge pipe, forming microbubbles from the aeration nozzle. The protective net and the mounting base are fixed by the mounting screw, and the spiral anchor at the bottom of the screw is screwed into the silt to enhance the stability of the component installation. The hand-tightening screw design allows the protective net to be quickly disassembled and assembled, which is convenient for maintenance of the oxygen pipe and nozzle. This structure combines mechanical connection with fluid transmission, which not only ensures the continuity of oxygen supply, but also simplifies the maintenance process, and is suitable for long-term stable operation in aquaculture ponds and other scenarios.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please refer to Figure 1-5 This embodiment of a multi-point oxygen supply device for freshwater aquaculture includes an oxygen pipeline 1, an installation mechanism 2 is fixedly installed on one side of the oxygen pipeline 1 in a linear arrangement at equal intervals, an oxygen supply component 3 is installed on the oxygen pipeline 1 through the installation mechanism 2, an oxygen supply hose 4 is fixedly installed on one side of the oxygen pipeline 1, and an oxygen supply pump 5 is fixedly connected to the outer end of the oxygen supply hose 4.

[0026] The installation mechanism 2 includes a regulating valve 21, with an external connecting pipe 22 fixedly connected to the outer end of the regulating valve 21. The regulating valves 21 are linearly arranged at equal intervals and fixedly installed on one side of the oxygen pipeline 1. The inner side of the external connecting pipe 22 is connected to the oxygen pipeline 1, and a sleeve 23 is fitted on the outer side of the external connecting pipe 22. A snap-fit ​​component 25 is fixedly connected to the top of the external connecting pipe 22. The oxygen supply component 3 is fixedly connected to the outer side of the sleeve 23. Both sides of the sleeve 23 have slots 24, and the end of the snap-fit ​​component 25 is inserted into the slot 24. During the application of this device, after the oxygen supply pump 5 is started, oxygen is delivered to the oxygen pipeline 1 through the oxygen supply hose 4. The oxygen is distributed to each oxygen supply unit through the regulating valve 21 and the external connecting pipe 22 connected to the oxygen pipeline 1. During installation, component 3 involves fitting the sleeve 23 onto the outside of the outer pipe 22. The end of the snap-fit ​​component 25 automatically inserts into the slots 24 on both sides of the sleeve 23, achieving a quick and secure connection between the oxygen supply component 3 and the outer pipe 22. This allows oxygen to enter the oxygen supply component 3 through the connection between the outer pipe 22 and the sleeve 23. During use, if maintenance or adjustment of the oxygen supply of a particular oxygen supply component 3 is required, the corresponding regulating valve 21 can be operated. The regulating valve 21 controls the connection between the outer pipe 22 and the oxygen pipeline 1, closing the faulty or malfunctioning branch without affecting the normal operation of other oxygen supply components 3. This design enables multi-point oxygen supply and independent control, ensuring uniform oxygenation of the aquaculture water and the stability of the system operation.

[0027] Please refer to Figures 1-3 and Figure 5The oxygen supply component 3 includes a connecting hose 31, which is fixedly connected to the outside of the socket 23. A mounting base 32 is fixedly connected to the outer end of the connecting hose 31. An oxygen exhaust pipe 33 is fixedly connected inside the mounting base 32. Aeration nozzles 34 are fixedly connected to the outer surface of the oxygen exhaust pipe 33 in a ring-shaped arrangement at equal intervals. A protective mesh cover 35 is inserted into the mounting base 32 outside the oxygen exhaust pipe 33, covering the outer sides of the oxygen exhaust pipe 33 and the aeration nozzles 34. Both ends of the mounting base 32 are threaded with mounting screws 36, which are used to install the protective mesh cover 35. A spiral anchor rod 37 is fixedly connected to the bottom of the mounting screw 36. The mounting screw 36 is a hand-tightening screw. During the application of this device, when the oxygen supply component 3 is working, oxygen enters the connecting hose 31 through the socket 23 and flows through the connecting hose... The oxygen is delivered to the oxygenation pipe 33 inside the mounting base 32, and then dispersed into tiny bubbles by the aeration nozzles 34 arranged in a ring on the outer surface of the oxygenation pipe 33. As these oxygen microbubbles rise, they come into full contact with the water, thus oxygenating the aquaculture water. During installation, the protective net cover 35 is placed over the outside of the oxygenation pipe 33 and the aeration nozzles 34. The hand-tightening installation screw 36 passes through the protective net cover 35 and is threaded into the mounting base 32. As the screw is tightened, the spiral anchor 37 at the bottom of the screw gradually screws into the silt at the bottom of the aquaculture pond, firmly fixing the mounting base 32 and completing the installation of the protective net cover 35 to prevent the aeration nozzles 34 from being damaged by collision. To disassemble, the hand-tightening installation screw 36 is rotated in the opposite direction, and the spiral anchor 37 is unscrewed from the silt, allowing the protective net cover 35 to be removed for easy inspection and maintenance of the oxygenation pipe 33 and the aeration nozzles 34.

[0028] Please refer to Figures 1-4The snap-fit ​​assembly 25 includes a top rail 251, which is fixedly connected to the top of the outer tube 22. Limit springs 252 are fixedly connected to both ends of the top rail 251. A slider 253 is fixedly connected to the end of each limit spring 252. A connecting arm 254 is fixedly connected to the top of the slider 253. A limit block 255 is fixedly connected to the inner side of the outer end of the connecting arm 254. The end of the limit block 255 is inserted into the slot 24. An adjustment assembly 256 is provided on the top of the top rail 251. The adjustment assembly 256 includes a push block 2561 and an adjustment guide rail 2562. The adjustment guide rail 2562 is fixedly connected to the middle of the top of the top rail 251. The moving block 2561 is fixedly connected to the top of the connecting arm 254. Limit springs 252 are fixedly connected to both ends of the adjusting guide rail 2562. A movable block 2564 is fixedly connected to the end of each limit spring 252. A guide frame 2565 is fixedly connected to the top of the movable block 2564. The guide frame 2565 and the pushing block 2561 are connected in a transmission manner. The end of the guide frame 2565 closest to the connecting arm 254 is generally an isosceles trapezoid. The inclined surface of the guide frame 2565 is in contact with the surface of the pushing block 2561. An adjusting plate 2563 is fixedly connected to the top of the guide frame 2565 on the side away from the oxygen supply component 3. The upper part of the adjusting plate 2563... The device has a circular overall shape. During use, when installing the oxygen supply component 3, the sleeve 23 is fitted onto the outside of the outer pipe 22. The limiting springs 252 at both ends of the top rail 251 are compressed. Their restoring force pushes the slider 253 to slide inward along the top rail 251. The slider 253 drives the connecting arm 254 and the limiting block 255 to move synchronously, so that the limiting block 255 is inserted into the slots 24 on both sides of the sleeve 23, thus achieving a firm connection between the oxygen supply component 3 and the outer pipe 22. When it is necessary to disassemble the oxygen supply component 3, the adjustment group 256 is operated, and the adjustment plate 2563 is pulled. The adjustment plate 2563 drives the guide frame 2565 to adjust the guide rail 256. As the guide frame 2565 moves within 62, the end of the guide frame 2565 near the connecting arm 254 is an isosceles trapezoid, and its inclined surface is in contact with the surface of the push block 2561. As the guide frame 2565 moves, the inclined surface presses against the push block 2561. The push block 2561 is forced to push the connecting arm 254 outward against the elastic force of the limit spring 252 inside the top rail 251, thereby causing the limit block 255 to disengage from the slot 24. At this time, the sleeve 23 can be removed from the outer pipe 22, completing the disassembly of the oxygen supply assembly 3. The entire process achieves rapid and stable installation and disassembly of the oxygen supply assembly 3 through the transmission cooperation between the limit spring 252 and the inclined surface of the guide frame 2565.

[0029] Operating principle and advantages: In the technical solution of this utility model, by setting the installation mechanism 2, the overall disassembly and maintenance of the oxygen supply component 3 can be improved, and the time spent on subsequent disassembly and maintenance can be reduced. In specific use, when the sleeve 23 is sleeved on the outer surface of the outer pipe 22, the restoring force of the limit spring 252 pushes the slider 253 to move inward. The slider 253 drives the limit block 255 to move inward synchronously through the connecting arm 254, so that the limit block 255 is inserted into the slot 24 of the outer pipe 22. Through the snap-fit ​​cooperation between the limit block 255 and the slot 24, the sleeve 23 and the outer pipe 22 are fixedly connected, and the oxygen supply component 3 is then installed on the outside of the regulating valve 21. On the other hand, when a certain oxygen supply component 3 needs to be inspected and maintained, the pipeline passage can be closed by adjusting the corresponding regulating valve 21, while other oxygen supply components 3 still maintain normal oxygen supply, ensuring the stability of the overall oxygen supply system during the maintenance process. In the disassembly and assembly process, pushing the regulating plate 2563 drives the guide frame 2565 and the movable block 2564 to move. The inclined surface of the guide frame 2565 on the movable block 2564 squeezes the pushing block 2561. The pushing block 2561 opens the connecting arm 254 through the inclined surface guiding action, so that the limiting block 255 moves outward and disengages from the slot 24, so that the socket 23 can be quickly disassembled from the outer pipe 22, realizing the separation of the oxygen supply component 3 and improving maintenance efficiency.

[0030] The oxygen supply mechanism achieves automation and reliability in water oxygenation. After the oxygen pump 5 starts, it delivers oxygen into the oxygen pipeline 1. The oxygen enters the connecting hose 31 through the connection structure between the outer pipe 22 and the sleeve joint 23, and is then delivered to the oxygen discharge pipe 33 via the connecting hose 31. Finally, it is discharged from the aeration nozzle 34 on the oxygen discharge pipe 33. The discharged oxygen forms microbubbles that float upwards, thus achieving the oxygenation function of the water. During installation, the protective net cover 35 is inserted into the outside of the oxygen discharge pipe 33 on the mounting base 32, and the installation screw is turned. 36 moves downwards through the protective net cover 35, completing the fixed connection between the protective net cover 35 and the mounting base 32. At the same time, the spiral anchor rod 37 at the bottom of the mounting screw 36 is screwed into the silt at the bottom of the aquaculture pond, enhancing the installation stability of the oxygen supply component 3. When disassembling, simply twist the hand-operated mounting screw 36 in the opposite direction to move it upwards, and the protective net cover 35 can be quickly removed, facilitating the inspection and maintenance of the oxygen pipe and aeration nozzle 34. This structure, through the coordinated design of mechanical connection and fluid transmission, ensures the continuity of the oxygen supply process and the convenience of maintenance.
