Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a deep-water aerator for fish ponds used in aquaculture. Background Technology

[0002] An aerator is a machine commonly used in aquaculture. Its main function is to increase the oxygen content in the water to ensure that fish do not suffer from oxygen deficiency. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the pond water from deteriorating and threatening the fish's living environment.

[0003] The existing patent publication number is CN220044597U, which discloses a deep-water oxygenation device for fish ponds in aquaculture. This utility model can break up air bubbles to avoid the generation of large air bubbles, so that oxygen can be better dissolved in the water. At the same time, the filter screen can also prevent sludge from accumulating on the top of the microporous aerator, ensuring the oxygenation effect. In addition, while aerating and oxygenating, the air can be used to clean the top of the microporous aerator to avoid clogging.

[0004] However, when the deep-water aerator for aquaculture ponds disclosed in the above patent is used, the aerator pipe is fixedly connected to the bottom of the pond with bolts, which can easily damage the bottom structure of the pond and cause water leakage. Therefore, we propose a deep-water aerator for aquaculture ponds to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a deep-water aerator for aquaculture ponds, which can solve the problem that in the use of existing deep-water aerators for aquaculture ponds, the aeration pipe is fixedly connected to the bottom of the pond with bolts, which can easily damage the bottom structure of the pond and cause water leakage.

[0007] To solve the above-mentioned technical problems, this utility model provides a deep-water aerator for aquaculture ponds, which adopts the following technical solution: it includes an aeration pipe and a suspended air cushion. The suspended air cushion is arranged in a ring with four air cushions evenly distributed. A cross is fixedly connected between the four air cushions. An air conveying component is provided on the cross. A lifting component and a limiting component are provided between the aeration pipe and the cross.

[0008] The lifting assembly includes two sets of brackets, which are symmetrically distributed about the center line of the cross. Each set of brackets includes two support plates, which are fixedly installed on the top of the cross. A roller is rotatably arranged between the two support plates, and a rope is wound around the outer ring of the roller. A motor is fixedly installed on the side of one of the support plates, and the drive end of the motor is fixedly connected to the roller. One end of the rope passes through the cross and is fixedly connected to the oxygenation pipe.

[0009] The oxygenation pipe is equipped with a flow splitter assembly.

[0010] Preferably, the limiting component includes two limiting rods, which are symmetrically distributed about the center line of the cross. The limiting rods are slidably connected to the cross, and a counterweight is fixedly provided at the lower end of each limiting rod. The counterweight is fixedly connected to the oxygenation pipe.

[0011] Preferably, the gas delivery assembly includes an air pump, which is fixedly installed in the middle of the top of the cross, and a housing is fixedly installed on the top of the air pump. A solar panel is fixedly installed on the top of the housing, and the air outlet of the air pump is connected to an oxygenation pipe via a corrugated pipe.

[0012] Preferably, the diversion assembly includes a diversion tube, which is fixedly disposed on the outer ring of the aeration tube. Several diversion tubes are equidistantly distributed along the length of the aeration tube. Two symmetrically distributed microporous aerators are fixedly disposed on the top of the diversion tube. A cleaning component is disposed on the diversion tube.

[0013] Preferably, the cleaning component includes a rotating shaft, which is rotatably connected to a diverter pipe via a sealed bearing. A driven plate is fixedly installed at the upper end of the rotating shaft, and scrapers are fixedly installed at both ends of the bottom of the driven plate. The scrapers are in movable contact with the microporous aerator. A fan blade is fixedly installed at the outer ring of one end of the rotating shaft that extends into the diverter pipe, and the fan blade is evenly arranged in a ring with no less than three blades.

[0014] Preferably, there is a gap between the fan blade and the inner wall of the diverter.

[0015] Preferably, the two counterweights are symmetrically distributed about the centerline of the oxygenation tube.

[0016] In summary, this utility model has at least one of the following beneficial effects:

[0017] 1. The oxygenation pipe of this utility model does not need to be fixedly connected to the bottom of the fish pond with bolts, and can still supply oxygen to the deep water area of ​​the fish pond. This solves the problem that when using existing deep water aerators for aquaculture fish ponds, the oxygenation pipe is fixedly connected to the bottom of the fish pond with bolts, which can easily damage the bottom structure of the fish pond and cause the fish pond to leak.

[0018] 2. By installing the lifting and limiting components, two motors are started simultaneously to drive the rollers to rotate, thereby performing rope winding and unwinding operations. By setting the counterweight and limiting rod, the oxygenation pipe is moved stably upward or downward, so that the oxygenation pipe can be located at the bottom of the pool, thus catering to pools of different depths and improving the applicability of the device.

[0019] 3. After installing the air supply component and the diversion component and adjusting the height of the oxygenation pipe, start the air pump. The air is then supplied to the oxygenation pipe through the corrugated pipe, and then broken and refined through the diversion pipe and the microporous aerator. This increases the contact area between the air and water, thereby increasing the amount of dissolved oxygen and improving the practicality of the device.

[0020] 4. With the installation of the cleaning components, when air passes through the diverter, it drives the fan blades to rotate, which in turn drives the rotating shaft, driven plate and scraper to rotate, so that the scraper can clean the surface of the microporous aerator and avoid the problem of the microporous aerator being blocked by impurities.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides an embodiment of a deep-water aerator for aquaculture ponds, comprising an aeration pipe 7 and a suspended air cushion 1. Four suspended air cushions 1 are evenly arranged in a ring, and a cross 2 is fixedly connected between the four air cushions 1. An air supply component is installed on the cross 2. A lifting component and a limiting component are installed between the aeration pipe 7 and the cross 2. The lifting component includes two sets of supports symmetrically distributed about the center line of the cross 2. Each set of supports includes two support plates, which are fixedly installed on the top of the cross 2. A roller 10 is rotatably arranged between the two support plates. A rope 12 is wound around the outer ring of the cross 2. A motor 11 is fixedly installed on the side of one of the support plates. The drive end of the motor 11 is fixedly connected to the roller 10. One end of the rope 12 passes through the cross 2 and is fixedly connected to the oxygenation pipe 7. The limiting component includes two limiting rods 14. The two limiting rods 14 are symmetrically distributed about the center line of the cross 2. The limiting rods 14 and the cross 2 are slidably connected. A counterweight 13 is fixedly installed at the lower end of the limiting rods 14. The counterweight 13 is fixedly connected to the oxygenation pipe 7. The two counterweights 13 are symmetrically distributed about the center line of the oxygenation pipe 7. A diversion component is installed on the oxygenation pipe 7.

[0030] In use, the aerator floats on the water surface by setting four suspended air cushions 1. Two motors 11 are started simultaneously, driving the roller 10 to rotate, thereby raising and lowering the rope 12. The counterweight 13 and the limiting rod 14 drive the aerator 7 to move stably up or down, so that the aerator 7 can be located at the bottom of the pool, thus accommodating pools of different depths and improving the applicability of the device.

[0031] In addition, the oxygenation pipe 7 of this utility model does not need to be fixedly connected to the bottom of the fish pond with bolts, and can still supply oxygen to the deep water area of ​​the fish pond. This solves the problem that when existing aerators for deep water fish ponds used in aquaculture are used, the oxygenation pipe 7 is fixedly connected to the bottom of the fish pond with bolts, which can easily damage the bottom structure of the fish pond and cause water leakage.

[0032] Furthermore, the gas supply assembly includes an air pump 3, which is fixedly installed in the middle of the top of the cross 2. A housing 4 is fixedly installed on the top of the air pump 3, and a solar panel 5 is fixedly installed on the top of the housing 4. The air outlet of the air pump 3 is connected to the oxygenation pipe 7 through a corrugated pipe 6. The diversion assembly includes a diversion pipe 8, which is fixedly installed on the outer ring of the oxygenation pipe 7. Several diversion pipes 8 are evenly distributed along the length of the oxygenation pipe 7. Two symmetrically distributed microporous aerators 9 are fixedly installed on the top of the diversion pipe 8.

[0033] Specifically, after adjusting the height of the oxygenation pipe 7, the air pump 3 is started, and air is delivered to the oxygenation pipe 7 through the corrugated pipe 6. The air is then broken and refined through the diversion pipe 8 and the microporous aerator 9, increasing the contact area between the air and water, thereby increasing the amount of dissolved oxygen and improving the practicality of the device.

[0034] Considering that the oxygenation pipe 7 is located at the bottom of the water, fish feces or other impurities often accumulate there, which can easily cause the surface of the microporous aerator 9 to become clogged and affect the oxygen supply of the device. Therefore, a cleaning component is installed on the diversion pipe 8. The cleaning component includes a rotating shaft 15, which is rotatably connected to the diversion pipe 8 through a sealed bearing. A driven plate 16 is fixedly installed at the upper end of the rotating shaft 15. Scrapers 17 are fixedly installed at both ends of the bottom of the driven plate 16. The scrapers 17 and the microporous aerator 9 are in movable contact. A fan blade 18 is fixedly installed at the outer ring of the end of the rotating shaft 15 that extends into the inside of the diversion pipe 8. There are no fewer than three fan blades 18 arranged in a ring evenly. There is a gap between the fan blades 18 and the inner wall of the diversion pipe 8.

[0035] Specifically, when air passes through the diversion pipe 8, it drives the fan blade 18 to rotate, which in turn drives the rotating shaft 15, the driven plate 16 and the scraper 17 to rotate, so that the scraper 17 can clean the surface of the microporous aerator 9 and avoid the microporous aerator 9 from being blocked by impurities.

[0036] Working Principle: In use, this invention uses four suspended air cushions 1 to allow the aerator to float on the water surface. Two motors 11 are started simultaneously, driving the roller 10 to rotate, which in turn retracts and extends the rope 12. The counterweight 13 and the limiting rod 14 drive the aerator 7 to move stably up or down, so that the aerator 7 can be located at the bottom of the pool, thus accommodating pools of different depths. After adjusting the height of the aerator 7, the air pump 3 is started, and air is delivered to the aerator 7 through the corrugated pipe 6. The air is then broken and refined through the diversion pipe 8 and the microporous aerator 9, increasing the contact area between the air and water, thereby increasing the dissolved oxygen. When the air passes through the diversion pipe 8, it drives the fan blade 18 to rotate, which in turn drives the rotating shaft 15, the driven plate 16, and the scraper 17 to rotate. This allows the scraper 17 to clean the surface of the microporous aerator 9, preventing the microporous aerator 9 from being blocked by impurities.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
