Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygenation device technology, and in particular to a high-efficiency aeration device for aquaculture. Background Technology
[0002] Aquaculture oxygenation devices are equipment used in aquaculture environments. Their main function is to increase the dissolved oxygen content in the water to meet the needs of aquatic animals for survival, growth, and reproduction. These devices use physical, chemical, and biological methods to integrate oxygen from the air and other oxygen-containing compounds into the aquaculture water, thereby improving the dissolved oxygen status of the water.
[0003] Existing aquaculture oxygenation devices use an internal air compressor to generate gas, which is then transported to microporous aeration pipes via main and branch pipes. These pipes have numerous tiny pores on their walls, ranging in diameter from tens to hundreds of micrometers. When gas escapes from these pores, it forms tiny bubbles in the water. These microbubbles have a large contact area with the water and rise slowly, allowing sufficient time for oxygen to dissolve. This method ensures even oxygen distribution in the water, effectively increasing dissolved oxygen levels. However, in aquaculture environments, the water contains various impurities such as silt, algae, microorganisms, and organic debris. These impurities can clog the micropores, preventing gas from escaping properly and leading to uneven oxygenation and insufficient dissolved oxygen in some areas. For stubborn impurities, such as scale that has formed within the micropores and biofilm tightly bound to the aeration pipe walls, ultrasonic treatment can be more effective. The cavitation and vibration effects of waves cannot completely remove these impurities. Over time, these remaining impurities will still affect the normal operation of the aeration pipes. Existing technologies involve coating the surface of the aeration pipes with a layer of antifouling, antibacterial, and self-cleaning properties, such as nano-titanium dioxide coatings or fluorocarbon coatings. These coatings can reduce the adhesion of impurities to the surface of the aeration pipes and reduce the formation of biofilms, thereby reducing the probability of stubborn impurities causing blockages. However, over time and with increased use, the coatings themselves will age. For example, nano-titanium dioxide coatings may experience a decrease in photocatalytic activity and changes in crystal structure under long-term light and water conditions, resulting in a weakening of their self-cleaning and antifouling functions. Fluorocarbon coatings will also gradually lose their original performance due to chemical corrosion and ultraviolet radiation, leading to blockages in the aeration pipes and causing inconvenience to subsequent oxygenation operations. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a high-efficiency aeration device for aquaculture, which aims to improve the problem that the coating itself will age and cause blockage of the aeration pipe after long-term use and increased use.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency aeration device for aquaculture, comprising a base plate, an air compressor fixedly connected to the top of the base plate, a connecting pipe connected to the front side of the outer wall of the air compressor, an aeration pipe fixedly connected to the other end of the outer wall of the connecting pipe, a fixed short plate fixedly connected to the inner wall of the aeration pipe, a fixed short column rotatably connected to the rear side of the outer wall of the fixed short plate, an impeller fixedly connected to the rear end of the outer wall of the fixed short column, multiple scrapers fixedly connected at equal intervals around the outer wall of the impeller, a fixed long column fixedly connected to the middle of the outer wall of the impeller, a hard brush fixedly connected to the top of the fixed long column, and a fixing mechanism provided on the right side of the outer wall of the base plate, the fixing mechanism being used to reinforce the connection between the connecting pipe and the aeration pipe.
[0006] As a further description of the above technical solution:
[0007] The fixing mechanism includes a hollow square block, which is disposed on the right side of the outer wall of the base plate. A fixing frame is fixedly connected to the top of the hollow square block, and a locking tooth block is rotatably connected to the outer wall of the fixing frame. A spring is fixedly connected to the top of the hollow square block, and the top of the spring is fixedly connected to the bottom of the locking tooth block. An elongated inner sliding groove plate is fixedly connected to both the upper and lower sides of the outer wall of the connecting pipe, and a groove plate is slidably connected inside the elongated inner sliding groove plate.
[0008] As a further description of the above technical solution:
[0009] A warning sign is fixedly attached to the top of the air compressor.
[0010] As a further description of the above technical solution:
[0011] The air compressor has a protective shell that is slidably connected to the top right side to prevent accidental contact.
[0012] As a further description of the above technical solution:
[0013] A hollow box is fixedly connected to the top of the base plate, and a drawer is slidably connected inside the hollow box.
[0014] As a further description of the above technical solution:
[0015] A handle is fixedly connected to the right side of the outer wall of the drawer.
[0016] As a further description of the above technical solution:
[0017] A sealing ring is fixedly connected to the front side of the outer wall of the base plate.
[0018] As a further description of the above technical solution:
[0019] The outer wall of the handle is fixedly connected with an anti-slip sleeve.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the air inside the connecting pipe drives the impeller to rotate. When the impeller rotates, it first scrapes the dirt and debris in the aeration pipe holes and inside by the scraper on the outer wall. Then, the impurities and dirt are brushed away by the hard brush. This avoids the problem of the aeration pipe becoming blocked due to the aging of the coating after long-term use and increased use.
[0022] 2. In this utility model, pressing the toothed block compresses the top spring of the hollow block, causing the other side of the toothed block to lift up. Then, it moves into the interior of the hollow block via the sliding groove plate. After releasing the pressed toothed block, the spring returns to its original elasticity. Finally, the teeth at the bottom of the toothed block engage with the groove on the outer wall of the groove plate, reinforcing the connection between the connecting pipe and the aeration pipe. This prevents the connection from loosening due to prolonged air flow inside the connecting pipe, which would otherwise prevent the area originally responsible for oxygenation by the aeration pipe from receiving sufficient oxygen, thus avoiding the problem of aquatic death.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 2 includes a hollow square block 201, which is located on the right side of the outer wall of the base plate 1. A fixing frame 205 is fixedly connected to the top of the hollow square block 201. A locking tooth block 202 is rotatably connected to the outer wall of the fixing frame 205, and the locking tooth block 202 serves to fix and engage the blocks. A spring 206 is fixedly connected to the top of the hollow square block 201, and the top of the spring 206 is fixedly connected to the bottom of the locking tooth block 202. By pressing the locking tooth block 202, the bottom spring 206 is compressed, which allows the locking teeth at the bottom of the locking tooth block 202 to disengage from the groove plate 203. The groove on the outer wall is divided for adjustment. The upper and lower sides of the outer wall of the connecting pipe 11 are fixedly connected with a long inner sliding plate 204. The inner groove plate 204 is slidably connected to the inside of the long inner sliding plate 204. The groove plate 203 can be fixed by engaging with the tooth block 202. The top of the bottom plate 1 is fixedly connected with a hollow box 6. The hollow box 6 is slidably connected to a drawer 5. The drawer 5 can be used to store daily items. The right side of the outer wall of the drawer 5 is fixedly connected with a handle 3. The handle 3 can be used to open and close the drawer 5.
[0034] Specifically, by pressing the toothed block 202, the top spring 206 of the hollow square block 201 is squeezed, causing the other side of the toothed block 202 to lift up. Then, the grooved plate 203 inside the elongated inner sliding groove plate 204 on the outer wall of the sliding connecting pipe 11 moves into the interior of the hollow square block 201. Then, the pressed toothed block 202 is released, allowing the spring 206 to return to its original elasticity. Finally, the toothed block 202 at the bottom engages with the groove on the outer wall of the grooved plate 203, reinforcing the connection between the connecting pipe 11 and the aeration pipe 10. A hollow box 6 is fixedly connected to the top of the base plate 1. A drawer 5 is slidably connected inside the hollow box 6. The drawer 5 can conveniently store everyday items. A handle 3 is fixedly connected to the right side of the outer wall of the drawer 5. The handle 3 can facilitate opening and closing the drawer 5 for use.
[0035] Reference Figure 1 and Figure 2 A sealing ring 12 is fixedly connected to the front side of the outer wall of the base plate 1. The sealing ring 12 can enhance the sealing of the connecting pipe 11 and prevent internal air leakage. An anti-slip sleeve 4 is fixedly connected to the outer wall of the handle 3.

[0036] Specifically, a sealing ring 12 is fixedly connected to the front side of the outer wall of the base plate 1. The sealing ring 12 can enhance the sealing of the connecting pipe 11 and prevent internal air leakage. An anti-slip sleeve 4 is fixedly connected to the outer wall of the handle 3.

[0037] Working principle: Air compressor 7 delivers air to the connecting pipe 11 and the aeration pipe 10 at the front end. The delivered air drives the short column 14 fixed on the outer wall of the fixed short plate 13 and the impeller 15 at the rear end to rotate. When the impeller 15 rotates, it first scrapes the dirt and debris in the holes and inside of the aeration pipe 10 by the scraper 17 on the outer wall. Then, the impurities and dirt are brushed away by the long column 18 fixed in the middle of the outer wall of the impeller 15 and the hard brush 16 on the top. This avoids the problem of the aeration pipe 10 becoming blocked due to the aging of the coating after long-term use and the increase of the number of uses.
[0038] By pressing the toothed block 202 to compress the top spring 206 of the hollow square block 201, the other side of the toothed block 202 is lifted up. Then, it moves into the hollow square block 201 through the elongated inner sliding groove plate 204 on the outer wall of the sliding connecting pipe 11 and the inner groove plate 203. Then, the pressed toothed block 202 is released to allow the spring 206 to return to its original elasticity. Finally, the toothed block 202 at the bottom engages with the groove on the outer wall of the groove plate 203 to reinforce the connection between the connecting pipe 11 and the aeration pipe 10. This prevents the connection between the connecting pipe 11 and the aeration pipe 10 from loosening due to prolonged air flow inside the connecting pipe 11, which would otherwise prevent the area originally responsible for oxygenation by the aeration pipe 10 from receiving sufficient oxygen and thus cause the death of aquatic products.
