Description

Technical Field

[0001] This utility model relates to the field of aeration systems, specifically to an active pond aeration system. Background Technology

[0002] Maintaining sufficient dissolved oxygen in the water is an important factor for the healthy growth of aquatic products during aquaculture. Therefore, aeration systems are essential in aquaculture.

[0003] In existing technologies, the aeration devices in oxygenation systems generally employ impeller aerators. These aerators use a motor to drive an impeller to rotate and agitate the water, creating splashes and bubbles that draw air into the water, passively forcing oxygen into the water for dissolved oxygen. However, the impeller generates significant noise during agitation, which can cause stress to aquatic products. Furthermore, due to the rising nature of gases during agitation, the air in passive oxygenation has a short residence time in the water, and only a portion of the air is drawn into the water, resulting in significant air loss and low oxygenation efficiency.

[0004] The existing technology has the following problems: during the oxygenation and aeration process, only a portion of the air is drawn into the water, resulting in significant air loss and low oxygenation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an active pond aeration system to address the above-mentioned problems, thereby solving the issues of excessive air loss and low aeration efficiency in existing technologies.

[0006] To achieve the above objectives, this utility model discloses an active pond aeration system, including an air supply device, a main air pipe connected to the air supply device, a branch air pipe connected to the main air pipe, and an aeration device installed in the pond water. The aeration device includes an aeration pipe connected to the branch air pipe and a cover fitted on the aeration pipe. The aeration pipe is provided with multiple aeration holes, and the side wall of the cover is provided with multiple breathable micropores. A support is provided below the aeration device for supporting the aeration device.

[0007] Using the above structure, the air supply device actively provides air to the water. The air transmitted through the main air pipe is diverted through the branch air pipes, which then transmit the air supplied by the air supply device to the aeration device. Air is then injected into the water through the aeration holes on the aeration pipe, ensuring that all air is input into the water with minimal air loss. The cover not only prevents debris from entering the aeration pipe, protecting it, but also, through its permeable micropores, disperses the air discharged from the aeration holes into finer bubbles, significantly increasing the contact area between air and water and more effectively promoting the further dissolution of oxygen in the water. The brackets fix the aeration device to a certain height, preventing it from swaying due to buoyancy and easily falling off, and also preventing it from being covered by sediment at the bottom of the pond, thus affecting the aeration effect. This solves the problem in existing technologies where only a portion of the air is drawn into the water during oxygenation, resulting in significant air loss and low oxygenation efficiency.

[0008] As a further improvement of this utility model, the main air pipe is arranged along the perimeter of the pond and has a rectangular structure with two opposing long sides. Multiple branch pipes are spaced apart along the long sides of the main air pipe. Multiple aeration devices are distributed inside the two long sides of the rectangular main air pipe structure. With this structure, the internal pressure of the rectangular main air pipe is balanced during air transmission, resulting in smoother airflow and reduced deformation, thus exhibiting better stability. The multiple branch pipes spaced apart along the long sides of the main air pipe evenly distribute the air transmitted by the main air pipe to each aeration device. The aeration devices are distributed along the inner sides of the two long sides of the rectangular main air pipe structure, achieving oxygenation throughout the pond and maintaining a balanced oxygenation level in each area, thus providing a balanced growth environment for the aquatic products cultivated in the pond.

[0009] As a further improvement of this utility model, there are multiple main air pipes, with the shorter side of the rectangular structure of each main air pipe serving as the middle pipe. The main air pipes are connected to each other through a middle pipe. An air supply device is installed on the middle pipe to simultaneously supply air to the main air pipes on both sides of the air supply device. Using the above structure, an expandable aeration system is formed through multiple main air pipes, allowing for adaptive adjustment of the system size according to different pond sizes. The interconnected main air pipes ensure uniform air transmission throughout the aeration system, achieving balanced oxygenation in each area. Two adjacent main air pipes share a single air supply device, ensuring consistent oxygenation on both sides of the pond, thus creating a balanced growth environment for aquatic products, and also saving costs by reducing the number of air supply devices required.

[0010] As a further improvement of this utility model, the bronchus is a flexible tube. With the above structure, the flexible tube has good flexibility, which can adapt to the complex slopes inside the pond and bypass obstacles, making the layout and installation of the bronchus more convenient; it can also buffer the impact of external forces on the bronchus, making it less prone to damage, thereby ensuring the oxygenation effect.

[0011] As a further improvement of this utility model, the main air pipe and the branch pipes are connected by a branch pipe connector. The branch pipe connector includes a first connecting pipe and a second connecting pipe. The section where the main air pipe connects to the branch pipe is disconnected, and the disconnected section is connected by the first connecting pipe. The wall of the first connecting pipe is connected to the second connecting pipe, and the inner cavity of the first connecting pipe communicates with the inner cavity of the second connecting pipe. A regulating valve is provided on the second connecting pipe, and the outlet of the regulating valve is connected to the branch pipe. With the above structure, the first connecting pipe allows the main air pipe to be extended in length as needed, and the second connecting pipe allows the branch pipes to be arranged according to the length extension of the main air pipe. The regulating valve controls the airflow and air volume in the branch pipes, enabling precise oxygenation of the water body according to different oxygenation requirements, and achieving flexible adjustment of the oxygenation amount.

[0012] As a further improvement of this utility model, the aeration pipe is annular. With the above structure, the annular aeration pipe can more evenly distribute water pressure and external forces, is less prone to deformation, has better stability, and the internal pressure of the annular pipe is balanced during air transmission, resulting in smoother airflow.

[0013] As a further improvement of this utility model, the support includes a first annular support and a second annular support, which are arranged vertically below the aeration device and connected by a support rod. The inner side of the first annular support is connected with intersecting first connecting rods. With this structure, the first and second annular supports match the shape of the aeration device, forming an annular line contact between the support and the aeration device. The connection via the support rod further stabilizes the support for the aeration device.

[0014] As a further improvement of this utility model, the bracket is provided with a fixing and height adjustment assembly for fixing the bracket and adjusting the installation height of the bracket. The fixing and height adjustment assembly includes a sleeve located at the center of the bracket, a fixing shaft inserted into the inner cavity of the sleeve and movably connected to the sleeve, the fixing shaft being used to fix it to the bottom of the pond, and a spiral blade at the lower part of the fixing shaft to prevent the fixing shaft from slipping off the bottom of the pond. The side wall of the sleeve is provided with a threaded hole, and the fixing shaft and the sleeve are fixed by a locking bolt screwed into the threaded hole. With the above structure, when the bottom of the pond is relatively hard, the aeration device is fixed to the bottom of the pond by the fixing shaft, and the spiral blade further secures the aeration device to the bottom of the pond, which can prevent the aeration device from moving due to water flow or other external forces. When multiple aeration devices are provided, it can prevent collisions between the aeration devices and thus prevent damage to the aeration devices. When the branch pipes are flexible hoses, it can prevent the branch pipes from getting tangled and thus blocking the airflow, affecting the aeration effect. In addition, by adjusting the connection height between the fixed shaft and the sleeve, and then fixing it with locking bolts, the installation height of the aeration device can be flexibly adjusted according to the different aeration height requirements of different aquatic products being farmed, and the installation height requirements of aeration devices for different pond heights or different water levels can also be met.

[0015] As a further improvement of this utility model, the air supply device is an air-suspended blower. With this structure, the impellers inside the blower rotate at high speed without contact or friction between them, requiring no lubrication, resulting in high blowing efficiency and thus improving oxygenation efficiency.

[0016] In summary, the beneficial effects of this utility model are as follows: It oxygenates the pond through an active oxygen supply system, using a main air pipe for transmission and branch pipes for distribution. The air supplied by the air supply system is transmitted to the aeration device, and then injected into the water through the aeration holes on the aeration pipe, ensuring that all air is incorporated into the water with minimal air loss, thus improving oxygenation efficiency. Multiple main air pipes form an expandable oxygenation system, allowing for adjustments to the size of the system to suit different pond sizes. The fixed and height-adjustable components enable flexible adjustment of the aeration device's height, meeting the needs of different pond heights or water levels. This solves the problem in existing technologies where only a portion of the air is drawn into the water during aeration, resulting in significant air loss and low oxygenation efficiency.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] Reference Figures 1 to 3 In some embodiments of this utility model, an active pond aeration system includes an air supply device 1, a main air pipe 2 connected to the air supply device 1, a branch air pipe 3 connected to the main air pipe 2, and an aeration device 4 disposed in the water body of the pond 11. The aeration device 4 includes an aeration pipe 41 connected to the branch air pipe 3 and a cover 42 sleeved on the aeration pipe 41. The aeration pipe 41 is provided with a plurality of aeration holes 411, and the side wall of the cover 42 is provided with a plurality of breathable micropores. A bracket 5 for supporting the aeration device 4 is provided below the aeration device 4, and the aeration device 4 and the bracket 5 are fixed together by fasteners 8.

[0026] Through the above improvements, the air supply device 1 actively supplies air to the water body. The air transmitted by the main air pipe 2 is diverted through the branch air pipe 3. The branch air pipe 3 transmits the air supplied by the air supply device 1 to the aeration device 4, and then fills the water body with air through the aeration holes 411 on the aeration pipe 41, so that all the air is input into the water body and the air loss is small. The cover 42 not only prevents the debris in the water body from entering the aeration pipe 41 and plays a protective role for the aeration pipe 41, but also the breathable micropores on the cover 42 can disperse the air discharged from the aeration holes 411 into finer bubbles, significantly increasing the contact area between the air and the water body, and more effectively promoting the further dissolution of oxygen in the air in the water body. The bracket 5 is used to fix the aeration device 4 and support it to a certain height, which can prevent the aeration device 4 from swinging with the buoyancy of the water body and causing the aeration device 4 to fall off easily, and also prevent the aeration device 4 from being covered by the mud and sand at the bottom of the pond 11 and affecting the aeration effect. This technology solves the problem that in existing oxygenation and aeration processes, only a portion of the air is drawn into the water, resulting in significant air loss and low oxygenation efficiency.

[0027] Reference Figure 1 In some embodiments of this utility model, the main air pipe 2 is arranged along the perimeter of the pond 11 and has a rectangular structure with two opposing long sides; multiple branch pipes 3 are spaced apart along the long side extension direction of the main air pipe 2; multiple aeration devices 4 are distributed on the inner side of the two long sides of the rectangular structure of the main air pipe 2. Through the above improvements, the internal pressure of the rectangular main air pipe 2 is balanced during air transmission, the airflow is smoother, and it is not easily deformed, thus having better stability; the multiple branch pipes 3 spaced apart along the long side extension direction of the main air pipe 2 evenly distribute the air transmitted by the main air pipe 2 to each aeration device 4. By distributing the aeration devices 4 along the inner side of the two long sides of the rectangular structure of the main air pipe 2, oxygenation is achieved in the entire area of ​​the pond 11, and the oxygenation in each area of ​​the pond 11 is kept balanced, providing a balanced growth environment for the aquatic products cultivated in the pond 11.

[0028] Reference Figure 1In some embodiments of this utility model, there are multiple main air pipes 2, with the shorter side of the rectangular structure of the main air pipe 2 serving as the middle pipe 21. The main air pipes 2 are connected to each other through a middle pipe 21. An air supply device 1 is installed on the middle pipe 21 to simultaneously supply air to the main air pipes 2 on both sides of the air supply device 1. The branch air pipes 3 are flexible hoses. Through the above improvements, multiple main air pipes 2 form an expandable aeration system, which can be adapted to the size of the aeration system according to the different sizes of the pond 11. The interconnection of multiple main air pipes 2 ensures uniform air transmission throughout the aeration system, achieving a balanced aeration amount in each area. Two adjacent main air pipes 2 share a single air supply device 1, which not only ensures that the aeration amount in the ponds 11 on both sides is consistent, thereby achieving a balanced aquatic product growth environment in the ponds 11 on both sides, but also saves costs by reducing the number of air supply devices 1. The flexible hose has good flexibility, which can adapt to the complex slope inside the pond 11 and bypass obstacles, making the layout and installation of the bronchus 3 more convenient; it can also buffer the impact of external forces on the bronchus 3, making the bronchus 3 less likely to be damaged, thereby ensuring the oxygenation effect.

[0029] Reference Figure 1 , Figure 4 In some embodiments of this utility model, the main air pipe 2 and the branch pipe 3 are connected by a branch pipe connector 6. The branch pipe connector 6 includes a first connecting pipe 61 and a second connecting pipe 62. The part of the main air pipe 2 that connects to the branch pipe 3 is disconnected, and the disconnected part is connected by the first connecting pipe 61. The wall of the first connecting pipe 61 is connected to the second connecting pipe 62, and the inner cavity of the first connecting pipe 61 communicates with the inner cavity of the second connecting pipe 62. The second connecting pipe 62 is provided with a regulating valve 63, and the air outlet of the regulating valve 63 is connected to the branch pipe 3. The aeration device 4 and the branch pipe 3 are connected by an air inlet connector 7. The air inlet connector 7 is provided with an interface portion 71 that connects to the branch pipe 3, and the interface portion 71 is provided with an anti-slip protrusion. The main air pipes 2 are connected by a main pipe connector 9, which is a T-shaped tee or an L-shaped tee. When connecting two disconnected horizontal main air pipes 2 and one vertical main air pipe 2, a T-shaped tee is used. When connecting a disconnected horizontal main air pipe 2 and a disconnected vertical main air pipe 2 at a bend, an L-shaped tee is used.

[0030] Through the above improvements, the first connecting pipe 61 allows the main air pipe 2 to be extended in length as needed, and the second connecting pipe 62 allows the branch air pipes 3 to be arranged according to the length extension of the main air pipe 2; the regulating valve 63 controls the airflow interruption and airflow magnitude of the branch air pipes 3 to achieve precise oxygenation of the water body according to different oxygenation needs, and realizes flexible adjustment of the oxygenation amount.

[0031] Reference Figures 1 to 3In some embodiments of this utility model, the aeration pipe 41 is annular; the support 5 includes a first annular support 51 and a second annular support 53 disposed below the aeration device 4 and distributed vertically, and the first annular support 51 and the second annular support 53 are connected by a support rod 52; the inner side of the first annular support 51 is connected with intersecting first connecting rods 54. Through the above improvements, the annular aeration pipe 41 can more evenly distribute water hammer pressure and external force, is not easily deformed, has better stability, and the internal pressure of the annular pipe is balanced during air transmission, resulting in smoother airflow. The first annular support 51 and the second annular support 53 match the shape of the aeration device 4, so that the support 5 forms an annular line contact with the aeration device 4, and the support rod 52 further connects to make the support 5 more stable in supporting the aeration device 4.

[0032] Reference Figure 5 , Figure 6 In some embodiments of this utility model, the bracket 5 is provided with a fixing and height adjustment assembly 10 for fixing the bracket 5 and for adjusting the installation height of the bracket 5. The fixing and height adjustment assembly 10 includes a sleeve 101 disposed at the center of the bracket 5, a fixing shaft 102 inserted into the inner cavity of the sleeve 101 and movably connected to the sleeve 101, and intersecting second connecting rods 55 connected to the inner side of the second annular bracket 53. The sleeve 101 is disposed between the first connecting rod 54 and the second connecting rod 55, and the sleeve 101 is centrally connected to the first connecting rod 54 and the second connecting rod 55. The fixing shaft 102 is used to fix to the bottom of the pond 11. The lower part of the fixing shaft 102 is provided with a spiral blade 103 to prevent the fixing shaft 102 from slipping off the bottom of the pond 11. The side wall of the sleeve 101 is provided with a threaded hole 104. The fixing shaft 102 and the sleeve 101 are fixed by a locking bolt 105 screwed into the threaded hole 104. One end of the locking bolt 105 is a threaded cylinder, and the other end is a ring structure. Through these improvements, when the bottom of the pond 11 is relatively hard, the aeration device 4 is fixed to the bottom of the pond 11 by the fixing shaft 102, and the spiral blade 103 further secures the aeration device 4 to the bottom of the pond 11, preventing the aeration device 4 from moving due to water flow or other external forces. When multiple aeration devices 4 are installed, it prevents collisions between them, thus preventing damage to the aeration devices 4. When the branch pipe 3 is a flexible hose, it prevents the branch pipes 3 from tangling and causing airflow blockage, thus affecting the aeration effect. Furthermore, by adjusting the connection height between the fixing shaft 102 and the sleeve 101, and then fixing it with the locking bolt 105, the installation height of the aeration device 4 can be flexibly adjusted according to the different aeration height requirements of different aquatic products being farmed, and it can also meet the needs of different pond heights or different water levels for the installation height of the aeration device 4.

[0033] Reference Figure 1In some embodiments of this utility model, the air supply device 1 is an air suspension blower. Through the above improvements, when the impellers inside the blower rotate at high speed, there is no contact or friction between the impellers, no lubrication is required, the blowing efficiency is high, thereby improving the oxygenation efficiency.

[0034] The working principle of this utility model is as follows: Air supply device 1 provides air, which is transmitted to branch air pipe 3 through main air pipe 2. Branch air pipe 3 divides the air and transmits it to aeration device 4. Aeration holes 411 on aeration pipe 41 disperse the air, and cover 42 further disperses the air into multiple microbubbles. The gas discharged from aeration holes 411 further diffuses, thereby promoting the dissolution of oxygen in the air into the water. Aeration device 4 is fixed to the bottom of pond 11 using fixed shaft 102. When it is necessary to adjust the installation height of aeration device 4 in the water, the connection height between fixed shaft 102 and sleeve 101 is adjusted, and then the fixed shaft 102 and sleeve 101 are fixed by locking bolt 105 passing through threaded hole 104.
