Description

Technical Field

[0001] This utility model relates to the technical field of push-water airlift aerators, and more specifically, to a push-water airlift aerator. Background Technology

[0002] Water-lift aerators are important equipment for ensuring dissolved oxygen levels in water bodies. As a key component of the aerator, the working condition of the impeller directly affects the oxygenation effect. However, existing water-lift aerators have many problems in the installation and disassembly of the impeller.

[0003] Traditional impeller installation methods typically involve bolt fastening, which requires various tools, involves cumbersome procedures, and consumes a significant amount of time and manpower. Furthermore, over long-term use, bolts are prone to rust and corrosion, making disassembly difficult and causing considerable inconvenience for equipment maintenance and repair. On the other hand, when the impeller is worn, damaged, or requires cleaning of attached debris, it cannot be replaced or repaired promptly, resulting in the aerator failing to operate normally and efficiently, affecting the aquaculture effect and increasing aquaculture costs.

[0004] Therefore, we made improvements and proposed a water-lifting aerator. Utility Model Content

[0035] Example 1

[0036] Please refer to Figure 1-5A push-air lift aerator includes two floats 1. A fixing frame 2 is fixedly installed between the tops of the two floats 1. The push-air lift aerator body 3 is fixedly installed on the top of the fixing frame 2. Connecting shells 4 are fixedly installed on the bottom of the front and rear sides of the push-air lift aerator body 3. A drive assembly 5 is fixedly installed on the bottom of the inner cavity of the push-air lift aerator body 3. Two protective shells 6 are provided on both sides of the drive assembly 5. An installation assembly 7 is fixedly installed on the top of the protective shell 6. A waterwheel aerator impeller 8 is provided on one side of the protective shell 6. A limiting post 9 is fixedly installed on one side of the waterwheel aerator impeller 8. Grooves 10 are provided on the front and rear sides of the limiting post 9. The drive assembly 5 includes a dual-rotor motor 501, which is fixedly installed at the bottom of the inner cavity of the push-water airlift aerator body 3. Rotating rods 502 are fixedly installed on both the front and rear sides of the dual-rotor motor 501. First bevel gears 503 are fixedly installed on opposite sides of the two rotating rods 502. Second bevel gears 504 mesh with the surfaces of the first bevel gears 503. A transmission rod 505 is fixedly installed inside the inner cavity of the second bevel gear 504. Support rings 506 are fixedly installed on both sides of the transmission rod 505. One side of each of the four support rings 506 is fixedly connected to one of the four protective shells 6. A limiting plate 507 is provided at the bottom of the surface of the dual-rotor motor 501. The side of the limiting plate 507 closest to the push-water airlift aerator body 3 is fixedly connected to the body 3. Support blocks 508 are movably connected to both sides of the surface of the transmission rod 505. The side of the support blocks 508 closest to the fixed frame 2 is fixedly connected to the fixed frame 2. Stabilizing blocks 11 are fixedly installed on the front and rear sides of the main body 3 of the push-water air-lift aerator. The side of the stabilizing block 11 closest to the connecting shell 4 is fixedly connected to the connecting shell 4.

[0037] In the implementation process, when oxygenation is required, the dual-rotor motor 501 is started. When the dual-rotor motor 501 is in use, it drives the rotating rod 502 to rotate. When the rotating rod 502 rotates, it drives the first bevel gear 503 to rotate. When the first bevel gear 503 rotates, it drives the second bevel gear 504 to rotate. When the second bevel gear 504 rotates, it drives the transmission rod 505 to rotate. When the transmission rod 505 rotates, it drives the support ring 506 to rotate. When the support ring 506 rotates, it drives the protective shell 6 and the waterwheel aerator impeller 8 to rotate. When the waterwheel aerator impeller 8 rotates, it stirs the water, causing the originally relatively calm water surface to produce waves, eddies and other water flow patterns. This breaks the air-to-water interface layer on the water surface, allowing more water to be exposed to the air. After the contact area between air and water increases, oxygen in the air can dissolve more fully into the water, thereby increasing the dissolved oxygen content of the water. Through the design of multiple waterwheel aerator impellers 8, the oxygenation efficiency can be increased.

[0038] Example 2

[0039] Mounting assembly 7 includes a threaded sleeve 701, which is fixedly mounted on the top of the protective shell 6. A threaded rod 702 is threadedly connected to the inner cavity of the threaded sleeve 701. A rotating disk 703 is fixedly mounted on the top of the threaded rod 702. A connecting plate 704 is movably connected to the bottom of the threaded rod 702. Push plates 705 are fixedly mounted on both sides of the bottom of the connecting plate 704. An inclined plate 706 is fixedly mounted on the opposite side of each of the two push plates 705. A movable wheel 707 is movably connected to the opposite side of each of the two inclined plates 706. An arc-shaped clamp 708 is fixedly mounted on the opposite side of each of the two movable wheels 707. A locking block 709 is fixedly mounted on the opposite side of each of the two arc-shaped clamps 708. A retaining ring 710 is fitted onto the surface of the threaded sleeve 701, and the retaining ring 710 is fixedly connected to the protective shell 6 on the side closest to the protective shell 6. A sliding block 711 is fixedly installed on one side of the arc-shaped clamp 708. A sliding rod 712 is slidably connected to the inner cavity of the sliding block 711. A return spring 713 is provided on one side of the surface of the sliding rod 712. The side of the return spring 713 near the sliding block 711 is fixedly connected to the sliding block 711. Both sides of the sliding rod 712 are fixedly installed in the inner cavity of the protective shell 6.

[0040] During implementation, when the impeller 8 of the waterwheel aerator needs to be installed, the impeller 8 is placed on one side of the protective shell 6. The rotating disc 703 is rotated, causing the threaded rod 702 to rotate. The threaded rod 702 moves downwards during rotation, causing the connecting plate 704 to move along with it. The two push plates 705 move along with the connecting plate 704, and the inclined plate 706 moves along with the push plates 705. The two arc-shaped clamps 708 are movably mounted on opposite sides of the two inclined plates 706 via two movable wheels 707, and move closer together as the inclined plates 706 move. When the fixture 708 moves, the sliding block 711 can also press the return spring 713. The locking block 709 will move along with the arc-shaped fixture 708, moving the two locking blocks 709 into the groove 10 on the limiting post 9, thereby installing the limiting post 9 and the waterwheel aerator impeller 8. When it is necessary to disassemble the waterwheel aerator impeller 8, the operation can be reversed. The design of the quick installation and disassembly mechanism makes the installation and disassembly of the impeller without the aid of tools, and can be completed with simple operation, which greatly saves maintenance time and labor costs, improves the maintenance efficiency of the equipment, and can be replaced or cleaned in a timely manner when the impeller has a problem, ensuring the normal operation of the aerator.
