Description

Technical Field

[0001] This invention relates to the field of aerators for fish farming, specifically a uniform underwater aerator. Background Technology

[0002] Since the oxygen naturally dissolved underwater in aquariums and other aquatic life breeding sites is often insufficient to meet the respiration needs of aquatic organisms, it is necessary to install aeration devices in aquariums and other aquatic life breeding sites to improve the survival rate of aquatic organisms.

[0003] Because some aquariums and other aquatic life-keeping areas are large, a single aeration device cannot provide uniform oxygenation to the entire area. The conventional approach is to deploy multiple aeration devices to achieve saturation oxygenation. This method requires a significant investment in equipment, increasing costs. Furthermore, current vortex ring aeration devices primarily control the bubble content within the water vortex rings, creating varying buoyancy in different rings and causing them to burst at specific locations. However, because the bubble content cannot be precisely controlled, differences in oxygen propagation occur between different vortex rings, failing to achieve uniform oxygenation. Therefore, there is an urgent need to develop a stable and uniform oxygen supply device to solve these problems. Summary of the Invention

Furthermore, current vortex ring aerators primarily control the bubble content within the vortex rings to create different buoyancy levels, causing them to rupture at specific locations. However, because the bubble content cannot be precisely controlled in this method, differences in oxygen propagation occur between different vortex rings, resulting in an inability to achieve uniform oxygenation.

The outer surfaces of the two second sliding valves are slidably connected to the side wall of the aerator body, and each of the two second sliding valves is fixedly connected to one side of its outer surface with an additional return spring. One end of the additional return spring is fixedly connected to the inside of the side wall of the aerator body.

[0012] Furthermore, a rear cover is fixedly connected to one end of the aerator body, and an oxygenation nozzle is fixedly connected to the other end of the aerator body.

[0020] The present invention has the following beneficial effects:

[0021] This invention proposes a uniform underwater aerator. Through an aerator pusher plate, an aerator pusher rod, a first sliding valve, and a second sliding valve, a mixed liquid is fed into the main chamber via a uniform water-bubble mixing process. The aerator pusher plate then compresses the mixed liquid within the chamber, causing it to flow from the aerator channel into the aerator nozzle, thereby generating vortex rings. Since these aerator vortex rings are generated from the same batch of mixed liquid, they have the same oxygen content. By controlling the stroke time of different vortex rings, the stability of the aerator vortex rings can be controlled, achieving rupture at different distances, ultimately resulting in uniform oxygenation.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example

[0032] like Figure 1 - Figure 7 As shown, this embodiment provides a uniform underwater aerator, including an aerator body 2. The aerator body 2 has a main cavity 3 inside. An aeration push plate 8 is slidably connected to the inner wall of the main cavity 3. Aeration push rods 10 are installed on both sides and the top of the outer surface of the aeration push plate 8. Multiple sets of first sliding valves 11 are installed on the side wall of the aerator body 2 at positions corresponding to the aeration push rods 10. Multiple guide rails 15 matching the first sliding valves 11 are opened on the inner wall of the aerator body 2. A water inlet 21 is opened at the bottom of the main cavity 3. The entire aerator body 2 is filled with water from the water inlet 21 at the bottom.

[0033] The oxygenation push rod 10 includes a connecting rod 1001 slidably connected to the side wall of the oxygenation push plate 8. The oxygenation push rod 10 is slidably connected to the side wall of the oxygenation push plate 8, and the side wall of the oxygenation push plate 8 is provided with a push rod telescopic groove 9 that matches the oxygenation push rod 10. The connecting rod 1001 is L-shaped, and a return slope 1003 is provided at the concave bend of the connecting rod 1001. A push rod limiting block 1002 is symmetrically fixedly connected to the side of the concave bend of the connecting rod 1001. A pushing slope 1004 is provided at one end of the connecting rod 1001, and a return spring 13 is fixedly connected to the other end of the connecting rod 1001 away from the pushing slope 1004. One end of the return spring 13 is fixedly connected to the inside of the side wall of the oxygenation push plate 8.

[0034] The first sliding valve 11 includes a panel 1101 slidably connected to the inner wall of the aerator body 2. Valve limiting blocks 1103 are fixedly connected to the top and bottom of the panel 1101. A valve inclined surface 1102 is provided on one side of the outer surface of the panel 1101, and the valve inclined surface 1102 matches the pushing inclined surface 1004. That is, when the aeration push plate 8 moves and drives the aeration push rod 10 to move, the pushing inclined surface 1004 of the aeration push rod 10 contacts the valve inclined surface 1102 of the first sliding valve 11.

[0035] The outer surfaces of the two valve limiting blocks 1103 are each fitted with a second sliding valve 12 that is slidably connected to the corresponding valve limiting block 1103. The outer surfaces of the two second sliding valves 12 are slidably connected to the side wall of the aerator body 2, and each of the outer surfaces of the two second sliding valves 12 is fixedly connected to another return spring 13. One end of the other return spring 13 is fixedly connected to the inside of the side wall of the aerator body 2. The second sliding valve 12 moves with the movement of the first sliding valve 11. When the second sliding valve 12 reaches the end of the groove opened on the side wall of the aerator body 2, it can no longer move. At this time, the pushing inclined surface 1004 of the aeration push rod 10 is resisted by the valve inclined surface 1102 of the first sliding valve 11, and will push the panel 1101 of the first sliding valve 11 vertically upward, so that it moves outward (in the direction of radial outward extension along the aerator body 2) and contacts the storage spring 14 in the storage cavity 19 described later, squeezing the storage spring 14 and temporarily storing it inside the storage cavity 19.

[0036] A rear cover 4 is fixedly connected to one end of the aerator body 2, and an oxygenation nozzle 1 is fixedly connected to the other end of the aerator body 2. A motor bracket 5 is fixedly connected to the inner side of the rear cover 4, and a drive motor 6 is fixedly installed on the inner side of the motor bracket 5. A lead screw 7 is fixedly connected to the output end of the drive motor 6. One end of the lead screw 7 is threaded through to the side wall of the oxygenation push plate 8. The drive motor 6 is a waterproof motor, which can drive the lead screw 7 at the output end to rotate when it is running, thereby driving the oxygenation push plate 8 to slide along the inner wall of the main cavity 3.

[0037] The aerator body 2 has multiple side outlets 16 and a top outlet 20 on the outer sides and top side walls corresponding to the first sliding valve 11. The inner walls of the multiple side outlets 16 on the same side are all connected to an aeration channel 17. One end of the aeration channel 17 is fixedly connected to an inlet pipe 18, and one end of the inlet pipe 18 is fixedly connected to the aeration nozzle 1. A switch valve (not shown in the figure) is installed at the bottom inlet 21. The water flow from the main cavity 3 will pass through the aeration channel 17 and the inlet pipe 18 in sequence and enter the interior of the aeration nozzle 1. The diameters of the three side outlets 16 are increasing and are not the same size. Therefore, when the aeration push plate 8 moves, different volumes of liquid can be pushed out due to the different diameters of the side outlets 16, resulting in different vortex travel times (different volumes of mixed liquid) when passing through the nozzle.

[0038] Each side outlet 16 and each top outlet 20 on the aerator body 2 is fixedly connected to a receiving cavity 19. A receiving spring 14 is fixedly connected to the inside of the receiving cavity 19. The stiffness of the spring connected to the aeration push rod 10 is greater than the stiffness of the receiving spring 14 and the return spring 13. The receiving cavity 19 is used to temporarily store the first sliding valve 11 when it is abutted.

[0039] Working principle: Initially, the oxygenation pusher plate 8 is located near the bottom inlet 21 of the main chamber 3. Under the action of the return spring 13, the first sliding valve 11 closes the first side outlet 16, and the top outlet 20 is closed in the same way. As the mixture of micron-sized bubbles and water enters the main chamber 3 from the bottom inlet 21, the oxygenation pusher plate 8 moves towards the drive motor 6. When the oxygenation pusher rod 10 installed in the pusher rod extension groove 9 of the oxygenation pusher plate 8 touches the first sliding valve 11, the first sliding valve 11 cannot move away from the bottom inlet 21 because the second sliding valve 12 is blocked by the sliding groove on the side wall of the aerator body 2. At this moment, the main chamber 3 is filled with the mixture, and the switch valve of the bottom inlet 21 is closed. At this time, the return slope 1003 touches the first sliding valve 11 and generates a component force, causing the oxygenation pusher rod 10 to move towards the pusher rod extension groove 9 and compress the return spring 13 installed therein. When the oxygenation push plate 8 leaves the first sliding valve 11, the oxygenation push rod 10 returns to its original position under the action of the return spring 13. Subsequent movements follow the same pattern, passing over the next two first sliding valves 11 in sequence. Since the stiffness of the spring connected to the oxygenation push rod 10 is greater than that of the receiving spring 14 and the return spring 13, the force generated by the force when the oxygenation push rod 10 moves forward is greater than that generated by the receiving spring 14 and the return spring 13. This force is insufficient to significantly compress the spring connected to the oxygenation push rod 10, thus preventing the oxygenation push rod 10 from disengaging from the first sliding valve 11 during its forward movement due to contraction towards the center of the oxygenation push plate 8. When the oxygenation push plate 8 returns, the sliding valve is restricted by the protrusion and cannot move away from the inlet 21. Therefore, at this time, the oxygenation push rod 10 compresses the connected spring, causing it to contract towards the center of the oxygenation push plate 8 and eventually move from the top of the sliding valve to a position away from the inlet 21.

[0040] When the equipment starts working and oxygenates the fish tank or fishpond, the drive motor 6 installed on the motor bracket 5 starts, driving the lead screw 7 to rotate, causing the oxygenation push plate 8 to squeeze the mixture in the main cavity 3. At the same time, the pushing inclined surface 1004 of the oxygenation push rod 10 contacts the first sliding valve 11, generating a thrust on the first sliding valve 11 away from the drive motor 6 and a thrust away from the center of the main cavity 3. Since the upper and lower sliding valve limit blocks 1103 correspond to the two second sliding valves 12 respectively, as the first sliding valve 11 moves, the second sliding valve 12 will gradually compress the return spring 13 and gradually open the first side outlet 16. The oxygenation push plate 8 compresses the main cavity 3, causing the mixed liquid to flow from the first side outlet 16 into the oxygenation channel 17, and further into the oxygenation nozzle 1 through the inlet pipe 18 connected to the oxygenation channel 17. When the first sliding valve 11 moves to the receiving cavity 19, it enters the receiving cavity 19 under the action of the thrust component and compresses the receiving spring 14 installed in the receiving cavity 19. At this time, the first side outlet 16 is in a fully open state. When the oxygenation push plate 8 passes the side outlet 16, the receiving spring 14 releases its elastic force, pushing the first sliding valve 11 out of the receiving cavity 19. At the same time, the return spring 13 releases its elastic force, pushing the first sliding valve 11 to close the first side outlet 16. The subsequent exercise process is the same. The oxygenation push rod 10 sequentially opens the first top water outlet 20, as well as the second and third side water outlets 16 and the second top water outlet 20.

[0041] And, as Figure 2 As shown, the side outlet 16 and the top outlet 20 are staggered. When the side outlet 16 on one side is completely closed, the top outlet 20 will immediately open, thus ensuring that the cavity will not be in a situation where all the side outlets 16 and the top outlet 20 are closed at the same time. One of them will always be open.

[0042] The mixed liquid is fed into the main cavity 3 through a uniform water-bubble mixing process. Then, the oxygenation pusher plate 8 squeezes the mixed liquid in the cavity, causing it to flow from the oxygenation channel 17 into the oxygenation nozzle 1, thereby generating a vortex ring. Since the oxygenation vortex rings are made from the same batch of mixed liquid, they have the same oxygen content. By controlling the stroke time of different vortex rings, the stability of the oxygenation vortex rings can be controlled, and different distances of rupture can be achieved, ultimately resulting in uniform oxygenation.

All modifications that can be directly derived or conceived by those skilled in the art from the content disclosed in this invention should fall within the protection scope of this invention.
