Description

Technical Field

[0001] The present application relates to the technical field of aquaculture oxygenation, and in particular to an aquaculture oxygenation system. Background Art

[0002] Oxygen is an essential substance for fish survival. The concentration of oxygen in the breeding pond directly affects the quality of life, growth rate, survival rate and quality of the fish. Especially under high temperature conditions, the dissolved oxygen concentration in the breeding pond will decrease, causing the fish in the breeding pond to suffocate and die.

[0003] Nowadays, people often use electric aeration devices to add oxygen. When the air pressure is low, or when experience shows that the water body lacks oxygen, or when the dissolved oxygen concentration in the water is low by connecting an oxygen meter, the aeration device is manually turned on to add oxygen to the aquaculture pond through the oxygen supply pipe.

[0004] However, in actual applications, oxygen is added to the aquaculture pond through the oxygen supply pipe, and the oxygen is concentrated in a local position in the aquaculture pond. Fish can only flock to the oxygen supply point. Due to the uneven distribution of dissolved oxygen concentration in different areas of the aquaculture pond, even if the oxygen supply is increased, it still cannot meet the needs of the fish in the entire aquaculture pond, resulting in fish deaths and economic losses. It also leads to excessive oxygen in some areas and waste. Summary of the Invention

[0005] In order to evenly distribute the oxygen supply in the aquaculture pond, the present application provides an aquaculture oxygenation system that can reduce economic losses.

[0006] The aquaculture oxygenation system provided in this application adopts the following technical solutions:

[0007] An aquaculture oxygenation system includes a dissolved oxygen sensor, an oxygenation device, an oxygenation grid, and a central controller, wherein the test end of the dissolved oxygen sensor and the oxygenation grid are both placed in a culture pond, the oxygenation grid is connected to the oxygenation device, the dissolved oxygen sensor and the oxygenation device are electrically connected to the central controller respectively, the oxygenation grid includes a frame and a plurality of oxygenation pipes, the plurality of oxygenation pipes are evenly arranged in the middle of the frame, the oxygenation pipes are connected to the frame, an air inlet is opened on the outer wall of the frame, the air inlet is connected to the oxygenation device, and a plurality of oxygenation holes are evenly opened on the outer wall of the oxygenation pipe.

[0008] By adopting the above technical solution, under the action of the dissolved oxygen sensor, the dissolved oxygen content in the breeding pond can be monitored in real time, and the data can be transmitted to the central controller to achieve accurate perception of the water quality environment and provide a reliable basis for subsequent oxygenation. In the present application, the oxygenation grid further refines the release of oxygen through the uniform arrangement of the frame and multiple oxygenation pipes, and the arrangement of multiple oxygenation holes on the oxygenation pipes, ensuring that oxygen can be evenly distributed to every corner of the breeding pond, improving the utilization rate of oxygen and the oxygenation effect. Compared with the prior art, the oxygenation system of the present application is based on the real-time monitoring data of the dissolved oxygen sensor. The central controller can intelligently judge the oxygenation demand and control the start and stop and operating power of the oxygenation equipment, thereby realizing automated and precise oxygenation management and effectively improving the efficiency and quality of aquaculture.

[0009] Preferably, a temperature sensor is included, a test end of the temperature sensor is placed in the breeding pond, and the temperature sensor is electrically connected to the central controller.

[0010] By adopting the above technical solution, temperature sensors are installed in the breeding pond to monitor water temperature changes in real time and transmit the data to the central controller, providing a more comprehensive environmental monitoring method for aquaculture. Combined with the real-time monitoring data of the dissolved oxygen sensor and the temperature sensor, the central controller can more accurately judge the environmental conditions of the breeding pond, thereby more accurately controlling the operation of the oxygenation equipment and ensuring that the water quality environment is always in the best condition.

[0011] Preferably, the oxygen-increasing hole is a circular hole or a trumpet hole whose diameter increases from the inside to the outside.

[0012] By adopting the above technical solution, the circular hole design is simple and practical, easy to process and manufacture, and can ensure uniform release of oxygen; and the trumpet hole design with increasing aperture from the inside to the outside helps to increase the oxygen release area, improve the oxygen diffusion rate and oxygenation efficiency; users can choose the appropriate aeration hole shape according to different aquaculture species and water quality conditions, and can more flexibly adjust the oxygenation effect to meet diverse aquaculture needs.

[0013] Preferably, the cross section of the oxygenation tube is rectangular or "<" shaped.

[0014] By adopting the above technical solution, the cross-section of the aeration pipe is rectangular, which is easier to produce and manufacture, and is conducive to saving cost; the cross-section of the aeration pipe is "<" shaped, which can further increase the contact area between the aeration pipe and water, help to improve the dissolution efficiency and diffusion rate of oxygen, and also make the structure of the aeration grid more compact, reducing space occupancy. At the same time, it helps to enhance the structural strength of the aeration pipe, improve its stability in water, and achieve the purpose of extending its service life.

[0015] Preferably, the oxygenation holes on two adjacent oxygenation tubes are staggered.

[0016] By adopting the above technical solution, the oxygenation holes on the two adjacent oxygenation pipes are staggered, which can ensure that oxygen is more evenly distributed to every corner of the breeding pond, reducing the occurrence of oxygenation blind spots. At the same time, the staggered arrangement helps to reduce mutual interference between oxygen flows, improve oxygen utilization efficiency, and thus reduce the energy consumption of the oxygenation equipment.

[0017] Preferably, a diffuser is installed between two adjacent oxygenation holes on the same oxygenation pipe to increase the water flow rate.

[0018] By adopting the above technical solution, the installation of the diffuser can effectively increase the water flow velocity, accelerate the diffusion of oxygen in the water, improve the oxygenation effect, further refine the oxygen distribution, and make oxygen more evenly dissolved in the water.

[0019] Preferably, the diffuser is a "T"-shaped structure or a "Y"-shaped structure, and the large end of the diffuser faces the oxygenation hole on the adjacent oxygenation pipe and close thereto.

[0020] By adopting the above technical solution, the diffuser has a "T"-shaped structure or a "Y"-shaped structure, which helps to disperse the water flow into multiple small flows, increase the contact area between the water flow and oxygen, and thus increase the dissolution rate of oxygen. In addition, the large end of the diffuser is directed toward the adjacent oxygenation holes on the adjacent oxygenation pipes, which helps to concentrate the oxygen to these areas, further improving the oxygenation efficiency.

[0021] Preferably, the diffuser is rotatably connected to the oxygenation pipe.

[0022] By adopting the above technical solution, when the oxygenating equipment is adding oxygen to the oxygenating grid, oxygen is ejected from the oxygenating hole of the oxygenating pipe. The speed of the water flow is increased while the oxygen is ejected. The accelerated water flow can also drive the diffuser to rotate, which helps to disperse the water flow into multiple small flows, increase the contact area between the water flow and the oxygen, thereby increasing the dissolution rate of oxygen and achieving the purpose of further refining the oxygen distribution.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Under the action of the dissolved oxygen sensor, the dissolved oxygen content in the breeding pond can be monitored in real time, and the data can be transmitted to the central controller to achieve accurate perception of the water quality environment and provide a reliable basis for subsequent oxygenation. In this application, the oxygenation grid further refines the release of oxygen through the uniform arrangement of the frame and multiple oxygenation tubes, and the provision of multiple oxygenation holes on the oxygenation tubes, ensuring that oxygen can be evenly distributed to every corner of the breeding pond, thereby improving the oxygen utilization rate and oxygenation effect;

[0025] 2. The installation of diffusers can effectively increase the water flow rate, accelerate the diffusion of oxygen in the water, improve the oxygenation effect, further refine the oxygen distribution, and make oxygen more evenly dissolved in the water. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiments of the present application disclose an aquaculture oxygenation system.

[0031] Example 1:

[0032] Reference Figure 1 and Figure 2 The aquaculture oxygenation system includes a dissolved oxygen sensor, an oxygenation device, an oxygenation grid 1 and a central controller, wherein the test end of the dissolved oxygen sensor and the oxygenation grid 1 are placed in the breeding pond, the oxygenation grid 1 is connected to the oxygenation device, and the dissolved oxygen sensor and the oxygenation device are electrically connected to the central controller respectively.

[0033] Specifically, the aeration grid 1 includes a frame 11 and multiple aeration pipes 12, which are evenly distributed in the middle of the frame 11 and connected to the frame 11. The outer wall of the frame 11 is provided with an air inlet 14, which is connected to the aeration equipment. The outer wall of the aeration pipe 12 is evenly distributed with multiple aeration holes 121. This system can automatically monitor and adjust the dissolved oxygen concentration in the aquaculture pond to achieve uniform oxygenation, reducing the uneven dissolved oxygen and resource waste problems encountered in traditional aeration methods.

[0034] In this application, the frame 11 can be made of stainless steel or plastic to provide excellent corrosion resistance and strength; alternatively, the aeration pipe 12 can be made of PVC or silicone to provide flexibility and durability. The length of the aeration pipe 12 can be adjusted according to the size of the aquaculture pond to ensure that the aeration grid 1 has sufficient gas flow capacity to provide a uniform and abundant amount of dissolved oxygen to the aquaculture pond.

[0035] Reference Figure 2The outer wall of the aeration tube 12 is uniformly provided with a plurality of aeration holes 121. The aeration holes 121 can be circular or trumpet-shaped, with the diameter increasing from the inside out. Circular holes are simpler to machine, while trumpet-shaped holes increase the diffusion area of ​​oxygen. Trumpet-shaped aeration holes 121 are preferred for improving oxygenation efficiency.

[0036] The oxygenation holes 121 are arranged in a staggered manner, that is, the oxygenation holes 121 on two adjacent oxygenation tubes 12 are staggered, thereby reducing the overlapping coverage of oxygen and further improving the oxygenation effect.

[0037] Furthermore, the shape of the full cross-section of the oxygenation tube 12 can be rectangular or "<"-shaped, that is, a circular tube or a V-shaped tube, among which the circular tube is simple and easy to process; the V-shaped tube can form a certain turbulence effect during the oxygenation process, enhance the mixing effect of oxygen, so as to promote the flow and diffusion of gas, improve the oxygenation efficiency, and also make the structure of the oxygenation grid 1 more compact and reduce space occupancy.

[0038] Reference Figure 2 A diffuser 13 is installed between two adjacent oxygenation holes 121 on the same oxygenation pipe 12 to guide the water flow, increase the water flow speed, and disperse the oxygen more evenly into the water. The diffuser 13 and the oxygenation pipe 12 are assembled in a rotating connection. The diffuser 13 can adopt a T-shaped structure or a Y-shaped structure, with the large end facing the oxygenation hole 121 on the adjacent oxygenation pipe 12 and close to it.

[0039] During use, when the oxygenation equipment is adding oxygen to the oxygenation grid 1, oxygen is ejected from the oxygenation hole 121 of the oxygenation pipe 12. The oxygen is ejected while increasing the speed of the water flow. The accelerated water flow can also drive the diffuser 13 to rotate. The diffuser 13 is a "T"-shaped structure or a "Y"-shaped structure, which helps to disperse the water flow into multiple small flows, increase the contact area between the water flow and the oxygen, thereby increasing the dissolution rate of oxygen, further refining the distribution of oxygen, and ensuring that the dissolved oxygen concentration in each area of ​​the breeding pond remains consistent.

[0040] Example 2:

[0041] This embodiment differs from the previous one in that it also includes a temperature sensor, with a test terminal placed within the aquaculture pond and electrically connected to a central controller. The temperature sensor monitors the water temperature in the aquaculture pond in real time. When the water temperature exceeds a certain threshold, the central controller automatically activates the aeration system to prevent the fish from being affected by a drop in dissolved oxygen concentration under high temperatures.

[0042] Specifically, the temperature sensor can be a thermistor or semiconductor temperature sensor, which offers fast response and high accuracy. The test end of the temperature sensor can be fixed to the bottom or sidewall of the aquaculture pond to accurately measure the water temperature. The temperature sensor is connected to the central controller via wireless or wired communication to ensure stable and reliable signal transmission.

[0043] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
