DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] like Figures 1 to 4 As shown, the utility model provides a technical solution: an aquaculture aeration oxygenator for creating wind and flow, comprising a fan assembly, a single-impeller fan 25, a reduction motor assembly 5, a main transmission shaft 23, a support box, a floating plate 12, an aeration pipe 13 and a blade 10 assembly; the fan assembly is connected to a fan motor 3, which is powered by the fan motor 3, the single-impeller fan 25 is transmission-connected to the upper end of the reduction motor assembly 5, the lower end of the reduction motor assembly 5 is connected to the main transmission shaft 23, and the reduction motor assembly 5 and the fan assembly are arranged on the support box. At the upper end, the main transmission shaft 23 extends from the upper end of the support box to the lower end of the support box, and the main transmission shaft 23 is connected to the support box through a shaft sleeve 20, and the lower end of the main transmission shaft 23 is connected to the blade 10 assembly; there are multiple floating plates 12, one end of the floating plate 12 is fixed on the support box, and the other end of the floating plate 12 extends to the outside of the support box, the aeration pipe 13 is arranged along the extension direction of the floating plate 12, and the end of the aeration pipe 13 extends downward to underwater, and the input end of the aeration pipe 13 is connected to the outlet of the single-impeller fan 25.

[0025] It can be understood that in this embodiment, the fan assembly provides downward wind force based on the action of the fan motor, pressing the oxygen above the water surface to the direction below the water surface, so that the blade assembly can drive the water flow during the rotation process, and at the same time, the water flow can absorb part of the oxygen into the water, or the oxygen can enter the water through the raised water droplets or steam attached to the oxygen, thereby increasing the oxygen content in the water; specifically, the reduction motor assembly transmits the power to the blade 10 assembly through the main drive shaft while the single-impeller fan 25 outputs the wind force, and sets the specific power conversion ratio as needed, so that the fan motor and the blade 10 have different rotation speeds. Among them, the fan 25 provides the power for oxygen supply and can accelerate the contact between water and oxygen. Specifically, the fan 25 transports air to the aeration pipe 13 connected to the air pipe 7 through the air pipe 7, and the aeration pipe 13 further transports the air to the water below the floating plate 12, and the water at the end of the aeration pipe 13 is flowing driven by the blades 10, which can further enhance the contact between oxygen and water. The support box provides an installation support here, and the floating plate 12 is made of foam or other polymer materials with buoyancy; in the embodiment, Figure 4 As shown, three floating plates 12 are provided, and the angle between each adjacent floating plate 12 is 120°. The ends of the floating plates 12 can be fixed by a pressing plate 9, and the pressing plate 9 and the floating plates 12 can be connected by a latch or by bolts.

[0026] It can also be understood that the single-impeller fan 25 can be set outside the supporting box. In this case, the counterweight of the supporting box needs to be adjusted as needed to make the center of gravity stable, or the user's original fan can be directly connected to provide a wind source.

[0027] In another possible embodiment, the fan assembly includes a fan blade 1 and a fan cover 26 . The fan cover 26 is located around the fan blade 1 to protect the fan blade 1 .

[0028] It is understandable that the fan cover 26 provides shielding for the fan. To facilitate the protection of the fan, the fan can also be connected to the device body in a detachable manner.

[0029] In another possible embodiment, a motor flange 2 is provided at the upper end of the fan motor 3, a reducer flange 24 is provided at the lower end of the reduction motor assembly 5, and a plurality of flange support rods 6 are provided between the motor flange 2 and the reducer flange 24.

[0030] It can be understood that in this embodiment, the click flange, the reducer flange 24 and the flange support rod 6 form an installation space, which allows the fan motor 3, the reducer motor assembly 5 and the main transmission shaft 23 of the fan to be located on the same axis and not easily offset. At the same time, a motor rain cover 4 can be installed between the motor flange 2 and the reducer flange 24 to further protect the motor and prevent rain and splashing water from affecting the life of the motor. Figure 4 As shown, in order to facilitate the display of the equipment structure, the motor rain cover 4 and the fan cover 26 are only partially presented. It should be known that they can completely wrap the structure to be protected according to the area to be protected.

[0031] In addition, Figure 1 As shown, at the lower end of the fan cover, based on the different positions of the fan motor, the motor rain cover can be set at the lower end of the fan cover and connected to the corresponding support component at the lower end through a support rod. Therefore, as a summary, the outer side of the fan motor is provided with a motor rain cover, and the shape of the motor rain cover can be semi-open, such as Figure 3 as shown, or closed, as Figure 1 shown.

[0032] In another possible embodiment, a plurality of first supporting connecting rods 14 are provided between the reducer flange 24 and the supporting box.

[0033] It can be understood that in this embodiment, since there is a certain distance between the reducer flange 24 located below and the upper surface of the support box, in order to facilitate installation and disassembly, the first supporting link 14 is provided to lift it up.

[0034] In another possible embodiment, the fan 25 is connected to the air pipe 7 via a reducer 21 .

[0035] It is understandable that, in this embodiment, the reducer 21 can increase the pressure in the air pipe 7, increase the flow rate of air in the air pipe 7, and enable the air to move quickly in the transmission direction. In addition, due to the structural design of this embodiment, a three-way pipe 19 is also provided between the reducer 21 and the air pipe 7.

[0036] In another possible embodiment, a fan flange is provided on the top of the single-impeller fan 25, and a plurality of second supporting connecting rods 22 are provided between the fan flange and the supporting box.

[0037] The support box body includes an upper cover plate 8, a lower cover plate 17 and a support plate 15. The support plate 15 is located between the upper cover plate 8 and the lower cover plate 17. A buoy 16 is also provided between the upper cover plate 8 and the lower cover plate 17. The cross-sections of the buoy 16 and the support box body are both hexagonal. There is a gap between the buoy 16 and the support plate 15, and the gap has an opening 27 every 120°.

[0038] It can be understood that, in the present embodiment, the upper cover plate 8, the lower cover plate 17 and the support plate 15 together form a support box, the support box is set to be a hollow structure, the float 16 is a hexagonal prism similar to the support box structure, wherein the side of the float 16 is set to be sealed, and the support box has an opening 27 at every 120° angle, the cross section of the float and the cross section of the support box are both hexagonal, the float is inscribed with the inner wall of the support box, and openings 27 are provided at the top corners of the support box at intervals of 120°. That is to say, the opening is used for water inlet and outlet. Specifically, during the operation of the entire device, if a rotational force is generated, water enters through the opening 27, and the inner wall of the opening 27 forms a reaction force, i.e., resistance, to offset most of the rotational force, so that the device can try to keep from following the rotation.

[0039] In another possible embodiment, the end of the floating plate 12 has an opening, and the air pipe 7 extends into the water through the opening. The extension length can be designed according to needs, and if the bottom of the pool needs to be modified, the extension length can be appropriately extended.

[0040] In another possible embodiment, the blade 10 assembly includes a connecting rod and a blade 10, the connecting rod is connected to the main transmission shaft 23, the blade 10 is fixed to the end of the connecting rod, and the blade 10 assembly is located inside the aeration pipe 13 extending underwater during rotation.

[0041] It is understandable that the connecting rods can be directly fixedly connected to the main transmission shaft 23, or connected to the main transmission shaft 23 using connecting parts such as a sleeve 20, and the blades 10 are located at the ends of the connecting rods to stir the water flow.

[0042] The blade 10 includes a vertical portion and an inclined portion 11, wherein the vertical portion is fixedly connected to the end of the connecting rod and is perpendicular to the water surface, and the upper end of the inclined portion 11 has a curling edge 18, and the inclined portion 11 is inclinedly arranged at the upper end of the vertical portion.

[0043] like Figure 4 As shown, the cross-section of the inclined portion 11 is a trapezoid or a triangle, and the inclined portion 11 is not at the same level as the vertical portion, but has an inclination angle toward the left. Based on the design of the rolled edge 18, the direction of water flow diffusion can be further expanded, while lifting the bottom deposits.

[0044] As an example, the single-impeller fan 25 drives the reducer and the blades 10, so that the straight water flow and the rising water flow in the water fully stir the organic matter in the water, lift the bottom deposits, generate upper and lower water convection, reduce the accumulation of ammonia nitrogen, prevent the bottom from stinking and reduce oxygen consumption. At the same time, water flow is generated on the periphery, and the fan creates wind to press the oxygen in the air into the water. The effects of sunlight and air achieve sterilization, improve the bottom, effectively decompose ammonia nitrogen and nitrite, and increase oxygen through aeration, so that the temperature and dissolved oxygen of the water surface and the bottom are fully kept consistent.

[0045] It is set to stir 800 tons of water in 1 minute. One aeration flow machine can cover about 4 mu of fish pond, and the effect can be achieved by 2-4 traditional water wheels, with energy saving reaching 90%. It can be equipped with mobile phone remote control (temperature, dissolved oxygen, pH value optional) real-time data viewing, automatic control timing control free switching, power off, phase loss, overcurrent, idling protection and alarm, which can greatly reduce breeding costs and increase profits.

[0046] The set power is 90W, the speed is 5 turns per minute, the current is 0.4A, the fan power is 90W, the current is 0.4A, the fan 25 power is 370W, the current is 0.6A, the operating voltage is 380V, the weight is 80 kg, and the coverage radius is 30 meters.

[0047] In another embodiment, if Figure 3 As shown, when a fan is not configured, the motor rain cover 4 can be an umbrella-shaped structure, the opening of which is downward, so as to shield the fan motor 3 and its necessary accessories, and the lower end of the rain cover is connected to the upper cover plate through a support rod.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
