Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a high-efficiency underwater oxygenation device. Background Art

[0002] In the fish farming industry, pond size is limited. When the number of fish is relatively small, the oxygen content in the water can meet the fish's survival needs. However, in order to raise more fish in a limited pond or to address the problem of uneven oxygen distribution within the pond, it is necessary to add an aerator to the pond. Conventional aerators use an air pump to force outside air into the pond through a pipe, dissolving oxygen in the water. However, this method has significant drawbacks. It only significantly increases oxygen content near the device. In areas further away from the device, the oxygen content does not increase significantly, which can easily lead to uneven oxygen distribution. While installing such aerators in multiple locations can achieve global oxygenation, energy consumption will increase significantly. Therefore, there is an urgent need for a device that can achieve global and uniform oxygenation while ensuring low power consumption within the fish pond. Summary of the Invention

[0047] Example 1

[0048] A high-efficiency underwater oxygenation device, such as Figures 1 to 14As shown, it includes a vortex ring generating device 2, a self-inhalation device 3, a driving device 4 and a vortex ring crushing device 5; the self-inhalation device 3 includes an intake chamber driving rod 32, an intake chamber 31 and an intake chamber driving motor 37, the intake chamber is in the shape of an ellipsoid, the intake chamber driving motor 37 is connected to the intake chamber through the intake chamber driving rod 32, and can drive the intake chamber to rotate around the intake chamber driving rod 32, the air inlet of the intake chamber is connected to the intake pipe 36, the air inlet of the intake chamber or the intake pipe 36 is provided with a one-way valve, the front and rear sides of the intake chamber are respectively provided with a front pull plate 41 and a rear push plate 42 that can move back and forth; the front pull plate 41 and the rear push plate 42 are first moved toward the direction close to the intake chamber to squeeze the intake chamber, so that the air in the intake chamber is injected into the mixing chamber through the gas pipeline 24 23, and then by moving away from the intake chamber, the intake chamber rebounds to inhale a corresponding amount of air, the front pull plate 41 and the rear push plate 42 repeat the above actions, the intake chamber repeatedly circulates the inhaled air and then injects the inhaled air into the mixing chamber 23, and the intake chamber driving motor 37 drives the ellipsoidal intake chamber to rotate, so that the front pull plate 41 and the rear push plate 42 squeeze the intake chamber at different times, the intake chamber driving motor 37 drives the intake chamber to rotate to different phase angles, because the squeezing movement distance of the front pull plate 41 and the rear push plate 42 is unchanged, the intake chamber rotated to different phase angles inhales and outputs different amounts of air when squeezed; the bubble vortex ring generated by the vortex ring generating device 2 can be transmitted to different distances, realizing global oxygenation and making the oxygen distribution uniform.

[0049] This device utilizes an elastic material to create an air intake chamber, which, in conjunction with an integral drive unit 4, completes both the air intake and vortex generation. Compared to conventional oxygenation devices, this device eliminates the need for a high-power pump and instead utilizes the entrainment of the water vortex as a transport for air bubbles. Furthermore, the air bubble content within the water vortex is controlled to achieve globally uniform oxygenation. This results in more uniform oxygenation and higher utilization rates.

[0050] The vortex ring generating device 2 includes a mixing chamber 23 and a vortex ring fluid pushing mechanism. The mixing chamber 23 is cylindrical as a whole and is arranged on one side of the air intake chamber. A reduction nozzle 20 is provided at one end of the mixing chamber 23 as a vortex ring outlet. A vortex ring fluid pushing mechanism is provided at the other end of the mixing chamber 23. An air inlet 23-3 is provided on the side wall of the mixing chamber 23. An air supply pipe 24 is connected between the air inlet 23-3 of the mixing chamber 23 and the air outlet of the air intake chamber 31. A one-way valve 35 is provided in the air inlet 23-3 of the mixing chamber 23 or the air supply pipe 24.

[0051] The vortex ring breaking device 5 is arranged above the outlet end of the vortex ring generating device 2;

[0052] The driving device 4 is connected to the front pull plate 41, the rear push plate 42 and the vortex ring fluid pushing mechanism respectively, providing power for the movement of the front pull plate 41, the rear push plate 42 and the action of the vortex ring fluid pushing mechanism.

[0053] Example 2

[0054] like Figure 12-13 As shown, the number of the suction chambers is limited on the basis of Example 1, and the performance of Example 2 after the limitation is better.

[0055] There are multiple suction chambers, which are arranged at a certain distance along the suction chamber drive rod 32. The suction chambers are staggered at different phases. The air inlet of each suction chamber is connected to an air intake pipe 36. There are multiple mixing chambers 23, which correspond to the suction chambers one by one. The mixing chambers 23 are connected to the corresponding suction chambers through the air pipeline 24.

[0056] The self-inhalation device 3 also includes an air diversion pipe 33 and an air intake main pipe 34. The air diversion pipe 33 is arranged on one side of the air intake chamber drive rod 32. Each air intake chamber is connected to the air diversion pipe 33 through an air intake pipe 36. The air intake main pipe 34 is connected to the air diversion pipe 33.

[0057] Furthermore, the number of the suction chambers is 4 to 12.

[0058] In the most preferred embodiment, the number of the suction chambers is 8, and the adjacent suction chambers on the suction chamber drive axis are distributed with a phase difference of 22.5°.

[0059] This device contains eight separate mixture vortex ring generating devices, which are driven by a drive unit 4 and a vortex ring breaking device 5. Each mixture vortex ring generating device includes a self-inhalation device 3 and a vortex ring generating device. The vortex ring generating device is first filled with water. The drive unit 4 squeezes the suction chamber in the self-inhalation device 3, injecting air bubbles into the vortex ring generating device, mixing the water and air. Finally, a push plate 29 pushes the mixture out of the mixing chamber 23, where it passes through the reducing nozzle 20 to form a water vortex ring entrained with air bubbles, namely a mixture vortex ring. After the air bubble injection, the suction chamber automatically returns to its original state due to the elasticity of its material, completing the suction process until it is squeezed by the drive unit 4 again. The device emits eight mixture vortex rings at a time. Due to the unique ellipsoidal structure of the suction chamber and the uniform distribution of the suction chambers of the eight suction devices with a 22.5° phase difference, the volume of the air bubbles output by adjacent suction chambers is different. Mixture vortex rings of the same size have different rising velocities due to their varying gas contents. A mixture vortex ring with a high volume of entrained bubbles rises faster than one with a low volume. This means they arrive at the fragmentation device at different times and locations, achieving a multi-point oxygenation effect. Combined with the inhalation chamber rotation device, the present invention can achieve globally uniform oxygenation over a period of time.

[0060] Furthermore, the front pull plate 41 is a rectangular plate, and a plurality of toothed plates are arranged in sequence along the length direction on the front pull plate 41. The number of the toothed plates is consistent with the number of the suction chambers and is arranged one to one. The rear push plate 42 is a rectangular plate; the toothed plates and the rear push plate 42 squeeze the corresponding suction chambers.

[0061] Furthermore, the front pull plate 41 is a rectangular plate as a whole, and its specific shape is tooth-shaped. Two circular holes are opened on the lower side for being coaxially fixed with the top of the driving rod of the pull plate driving motor 43, and two square holes are opened on the bottom for cooperating with the upper guide rail of the shell to form a sliding connection.

[0062] The rear push plate 42 is in the shape of a rectangular plate as a whole, with two round holes in the middle for coaxially connecting with the top of the driving rod of the push plate driving motor 44; the bottom of the rear push plate 42 has two square holes for cooperating with the guide rail on the upper layer of the shell to form a sliding connection.

[0066] Furthermore, there are two pull plate drive motors 43 and two push plate drive motors 44.

The device is divided into five parts: a frame system 1, a vortex ring generating device 2, a self-aspiration device 3, a driving device 4, and a vortex ring rupture device 5.

[0084] 1. Initial state:

[0085] In the initial state, the device is placed as a whole at the bottom of the fish pond, with one side close to the main suction pipe 34 in the self-inhalation device 3 extending out of the fish pond and exposed to the air. The eight suction chambers 31 are evenly distributed on the suction chamber drive shaft 32 with a phase difference of 22.5°, and are all in a restored state, filled with air. The mixing chamber 23 in the vortex ring generating device 2 is filled with water, and the push plate spring 28 is in a relaxed state. At this time, the pendulum needle 25 is in a rearward state. The pull plate drive motor 43 in the drive device 4 fully extends the drive rod, so that the front pull plate 41 is in the front position. The push plate drive motor 44 fully retracts the drive rod, so that the rear push plate 42 is in the rearward position.

[0086] 2. Inject air bubbles and store energy in the push plate spring 28:

[0087] The driving device [4] starts working, and the two push plate drive motors 44 and the two pull plate drive motors 43 start working at the same speed. The push plate drive motor 44 drives the rear push plate 42 to move forward, and the pull plate drive motor 43 drives the front pull plate 41 to move backward. Until the front pull plate 41 and the rear push plate 42 simultaneously contact the suction pipe 36. During this process, the suction chamber 31 is squeezed by the front pull plate 41 and the rear push plate 42 at the same time. Due to the different placement states of the eight suction chambers 31, the amount of gas squeezed out of each suction chamber 31 is different. Under the action of the one-way valve 35, the gas can only enter the mixing chamber 23 from the gas pipe 24 through the one-way valve 20. The rotating motor 21 drives the rotating impeller 22 to rotate, mixing the air bubbles and the water. During the forward movement of the rear push plate 42, the pendulum needle 25 is driven to gradually move forward from the rear state, and then the push plate driving cross bar 27 and the push plate driving arm 26 drive the push plate 29 from the front state to gradually move backward, while the push plate spring 28 is gradually compressed to store elastic potential energy.

[0088] 3. Complete the air bubble injection, release the elastic potential energy, and generate a vortex ring:

[0089] The front pull plate 41 and the rear push plate 42 simultaneously contact the air intake pipe 36, completing the injection of air bubbles, and at the same time, the water body and air bubbles are mixed under the action of the rotating impeller 22; at this time, the rear push plate 42 pushes the pendulum needle 25 completely to the forward state, and the pendulum needle 25 breaks away from the constraint of the rear push plate 42. The elastic potential energy stored in the push plate spring 28 is quickly released, driving the push plate 29 to push out the mixture of water and air bubbles, passing through the reduction nozzle 20, forming a water vortex ring that entrains a certain amount of air bubbles; while the push plate 29 moves forward, it drives the pendulum needle 25 back to the rear state through the push plate drive arm 26 and the push plate drive shaft 27. At this stage, eight water vortex rings carrying air bubbles are generated, and the amount of air bubbles contained in adjacent water vortex rings is different. The water vortex ring containing a large amount of air bubbles will float to the vortex ring breaking device 5 in advance due to its fast floating speed and large movement resistance. After the vortex ring is broken, the air bubbles are released, completing the nearby oxygenation. The water vortex ring containing a small amount of air bubbles will slowly float up to the vortex ring breaking device 5. After the vortex ring breaks, the air bubbles are released to complete the oxygenation at a distance.

[0090] 4. The suction chamber rotates as a whole, and the front pull plate and rear push plate are reset:

[0091] After a group of vortex rings carry air bubbles to complete the oxygenation task, the intake chamber 31 can quickly recover because it is made of elastic material. Driven by the intake chamber drive motor 37, the intake chamber 31 fixed to the intake chamber drive rod 32 begins to rotate as a whole, with a rotation angle of 22.5°. At the same time, the front pull plate 41 and the rear push plate 42 are reset under the drive of their respective drive motors; during the reset process, the rear push plate 42 will contact the pendulum needle 25 and push the pendulum needle 25 backward until the pendulum needle is freed from the constraint of the rear push plate 42 again. During this process, the push plate spring 28 will first be stretched and then return to a relaxed state, that is, the initial state.

[0092] Continue to repeat steps 234, repeating eight times (8×22.5°=180°) as one large cycle. In one large cycle, for a single vortex ring generating device, it is in the 0° state, the water vortex ring contains the least amount of bubbles, and it first performs oxygenation at the farthest point. During the process of the suction chamber 31 rotating from 0° to 90°, the amount of bubbles it carries gradually increases, and oxygenation begins gradually at the nearby area. When the device has rotated a cumulative total of 90°, the amount of bubbles it contains is the largest, and oxygenation at the nearest point is completed. During the process of the suction chamber rotating from 90° to 180°, the oxygenation point gradually moves from the near side to the far side. When the device has rotated a cumulative total of 180°, oxygenation at the farthest point is completed again. This achieves uniform oxygenation at multiple points. A single vortex ring generating device can complete uniform oxygenation on a line. This device contains eight vortex ring generating devices, which can complete global uniform oxygenation of the fish tank.

[0093] See Figure 13A diagram of the air volume control method explains how the suction chamber controls the output air volume. At 0°, after deformation, a large amount of gas remains inside, resulting in a smaller output volume. The resulting water vortex entrains a small amount of bubbles for distant oxygenation. At 90°, after deformation, less gas remains inside, resulting in a larger output volume. The resulting water vortex entrains a large amount of bubbles for nearby oxygenation.

[0094] In summary, this device uses elastic materials to make an air suction chamber, and cooperates with the overall driving device to complete the air suction action and vortex ring generation action of the device; compared with ordinary oxygenation devices, it abandons the high-power air pump device, and uses the entrainment effect of the water vortex ring as a means of transporting air bubbles, and then controls the content of air bubbles in the water vortex ring to achieve the effect of global uniform oxygenation. The oxygenation of this device is more uniform and the utilization rate is higher. The present invention can not only be used in aquaculture, but also in ornamental fish tanks. Under the premise of ensuring ornamental value and low power consumption, it can complete the global uniform oxygenation of the ornamental fish tank, and the overall integration of the device is relatively high.
