DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1

[0020] As Figures 1 - 3 shown, this embodiment provides a floating body structure for an aquaculture aerator, which includes a floating box 28 and a built-in floating cylinder 16. The cross-sections of the floating box 28 and the built-in floating cylinder 16 are both regular polygons. The built-in floating cylinder 16 is closed on all sides. The edge lines of the built-in floating cylinder 16 are in contact with the inner wall of the floating box 28. A plurality of openings 27 are provided on the side wall of the floating box 28, and a semi-open chamber is formed between the openings 27 and the built-in floating cylinder 16. Among them, a plurality of floating plates 12 are equidistantly arranged at equal intervals on the upper end of the floating box 28. Among them, the floating box 28, the built-in floating cylinder 16 and the floating plates 12 are all made of buoyancy materials. The cross-sections of the floating box 28 and the built-in floating cylinder 16 are both regular hexagons, and the openings 27 are directly opposite to the middle part of the side of the built-in floating cylinder 16, and the included angle between two adjacent openings 27 is 120°.

[0021] In this embodiment, it can be understood that a part of water can be accommodated in the cavity. On the one hand, the weight of the floating body is increased, making the resistance during its rotation larger. Secondly, the water in the cavity will impact the inner wall of the floating box 28 on the side opposite to the rotation during the rotation process due to obtaining kinetic energy, so that the inner wall of the floating box 28 on this side obtains an opposite force, thereby being able to slow down or prevent the rotation of the floating box 28.

[0022] Embodiment 2

[0023] This embodiment provides a technical solution: an aeration and oxygenation machine for aquaculture that creates wind and current and adopts the floating body structure of Embodiment 1, including a fan assembly, a reducer assembly 5, a main transmission shaft 23, a blower 25, an air pipe 7, a support box body (i.e., floating box 28), a floating plate 12, an air diffuser pipe 13, and a blade 10 assembly; the output motor 3 of the fan assembly is drivingly connected to the upper end of the reducer assembly 5, the lower end of the reducer assembly 5 is connected to the main transmission shaft 23, the reducer assembly 5 and the fan assembly are fixed to the upper end of the support box body, the main transmission shaft 23 extends from the upper end of the support box body to the lower end of the support box body, and the main transmission shaft 23 is connected to the support box body through a bushing 20, and the lower end of the main transmission shaft 23 is connected to the blade 10 assembly; the blower 25 is arranged on the support box body, and the output end of the blower 25 is connected to the air pipe 7, and the air pipe 7 is communicated with the air diffuser pipe 13; there are multiple floating plates 12, one end of the floating plate 12 is fixed to the upper end of the support box body, the air diffuser pipe 13 is arranged along the upper surface of the floating plate 12, and the end of the air diffuser pipe 13 extends into the water.

[0024] It can be understood that in this embodiment, the fan assembly provides downward wind force to press the oxygen above the water surface downward, so that during the rotation of the blade 10 assembly, while driving the water to flow, it can make the water flow inhale part of the oxygen into the water, or the oxygen attaches to the water through the raised water droplets or steam to enter the water, increasing the oxygen content in the water; specifically, the reducer assembly 5 transmits the power of the fan output motor 3 to the blade 10 assembly through the main transmission shaft 23, and sets a specific power conversion ratio according to needs, so that the fan and the blade 10 have different rotation speeds. Among them, the blower 25 provides the supply power of oxygen and can accelerate the contact between water and oxygen. Specifically, the blower 25 transports air to the air diffuser pipe 13 connected to the air pipe 7 through the air pipe 7, and the air diffuser pipe 13 further transports the air to the water below the floating plate 12, and the water at the end of the air diffuser pipe 13 is flowing driven by the blade 10, which can further improve the contact between oxygen and water. The support box body provides an installation and support function here, and the floating plate 12 is made of foam or other buoyant polymer materials; in the embodiment, such as Figure 1As shown, three floating plates 12 are provided, and the included angle between each adjacent floating plate 12 is 120°. The end of the floating plate 12 can be fixed by a pressing plate 9, and the pressing plate 9 and the floating plate 12 can be connected by a pin method or fixed by bolts.

[0025] It can also be understood that the fan can be arranged outside the support box body, or directly connected to the existing fan of the user to provide the air source. In addition, two output motors can be arranged in the embodiment. One supplies energy to the fan, and the other is connected to the main transmission shaft to supply energy to the blade assembly. The speed between the two output motors can be adjusted by a speed reducer.

[0026] 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.

[0027] It can be understood that the fan cover 26 provides protection for the fan. For the convenience of protecting the fan, the fan can also be connected to the equipment main body in a detachable manner.

[0028] In another possible embodiment, a motor flange 2 is provided at the upper end of the fan output motor 3, and a speed reducer flange 24 is provided at the lower end of the speed reducer assembly 5. There are several flange support rods 6 between the motor flange 2 and the speed reducer flange 24.

[0029] It can be understood that in this embodiment, the motor flange, the speed reducer flange 24 and the flange support rod 6 form an installation space, which makes the output motor 3, the speed reducer assembly 5 and the main transmission shaft 23 of the fan on the same axis and not easy to deviate. At the same time, a motor rain cover 4 can also be installed between the motor flange 2 and the speed reducer flange 24 to further protect the motor and prevent rainwater and splashed water from affecting the service life of the motor. As Figure 1 As shown, for the convenience of reflecting the equipment structure, the motor rain cover 4 and the fan cover 26 are only partially presented. It should be known that it can completely wrap the structure to be protected according to the area to be protected.

[0030] In another possible embodiment, several first support connecting rods 14 are provided between the speed reducer flange 24 and the support box body.

[0031] It can be understood that in this embodiment, since there is still a certain distance between the lower speed reducer flange 24 and the upper surface of the support box body in this embodiment, in order to facilitate installation and disassembly, the first support connecting rod 14 is provided to lift it up.

[0032] In another possible embodiment, the fan 25 and the air pipe 7 are connected by a reducing joint 21.

[0033] It can be understood that in this embodiment, the reducing joint 21 can increase the pressure in the air pipe 7, improve the flow rate of air in the air pipe 7, and enable the air to move rapidly in the transmission direction. In addition, due to the structural design of this embodiment, a tee pipe 19 is also provided between the reducing joint 21 and the air pipe 7.

[0034] In another possible embodiment, a support plate is provided at the bottom of the fan 25, and a plurality of second support link rods 22 are provided between the support plate and the support box body.

[0035] 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. An internal floating cylinder 16 is also provided between the upper cover plate 8 and the lower cover plate 17. The internal floating cylinder 16 and the cross section of the support box body are both hexagonal. There is a gap between the internal floating cylinder 16 and the support plate 15, and openings 27 are provided at intervals of 120° in this gap.

[0036] It can be understood that in this embodiment, the upper cover plate 8, the lower cover plate 17 and the support plate 15 together form the support box body. It is set that the inside of the support box body is a hollow structure, and the internal floating cylinder 16 is a hexagonal prism similar to the structure of the support box body. Among them, it is set that the side surface of the internal floating cylinder 16 is in a sealed state, and there is an opening 27 at each corner of the support box body at intervals of 120°. The cross section of the floating cylinder and the cross section of the support box body are both hexagonal, and the floating cylinder is inscribed in the inner wall of the support box body. Openings 27 are provided at the top corners of the support box body at intervals of 120°. That is to say, the openings are 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 a reaction force, that is, a resistance, is formed on the inner wall of the opening 27 to offset most of the rotational force, so that the device can try to remain non-rotating.

[0037] In another possible embodiment, the end of the floating plate 12 has an opening, and the air pipe 7 passes through the opening and extends into the water. The extended length can be designed according to needs. If the bottom of the pool needs to be modified, the extended length can be appropriately increased.

[0038] 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, and the blade 10 is fixed at the end of the connecting rod. The blade 10 assembly is located inside the aeration pipe 13 extending into the water during rotation.

[0039] It can be understood that the connecting rods can be directly fixed to the main transmission shaft 23, or a connecting piece such as a shaft sleeve 20 can be used to connect the main transmission shaft 23. The blade 10 is located at the end of the connecting rod and is used to stir the water flow.

[0040] Among them, the blade 10 includes a vertical portion and an inclined portion 11. The vertical portion is fixedly connected to the end of the connecting rod and is perpendicular to the water surface. The upper end of the inclined portion 11 has a curled edge 18, and the inclined portion 11 is inclinedly arranged at the upper end of the vertical portion.

[0041] The cross-section of the inclined portion 11 is trapezoidal or triangular, and the inclined portion 11 and the vertical portion are not on the same horizontal plane, but have an inclination angle towards the left. Based on the design of the curled edge 18, the direction of water flow diffusion can be further expanded, and at the same time, the bottom deposits can be lifted.

[0042] As an example, the motor drives the reducer and the blade 10 to fully stir the organic matter in the water with the linear water flow and the rising water flow in the water, lift the bottom deposits, generate water convection, prevent the bottom layer from emitting odor and reduce oxygen consumption. At the same time, water flow is generated on the periphery, and the fan generates wind to press the oxygen in the air into the water. The action of sunlight and air achieves sterilization, bottom improvement, effectively decomposes ammonia nitrogen and nitrite, and has the effect of efficient aeration and oxygenation, making the dissolved oxygen in the water surface and the bottom consistent.

[0043] It is set to stir 800 tons of water body per minute. One aeration and water flow generator can cover a fish pond of about 4 mu. The effect can reach that of 2 - 4 traditional water wheels, with an energy saving of 90%. Mobile phone remote control can be added (temperature, dissolved oxygen, pH value are optional), data can be viewed in real time, and automatic control and timing control can be freely switched. There are protections and alarms for power failure, phase loss, overcurrent, and idling, which greatly reduces the breeding cost and increases the income.

[0044] The set power is 90W, the rotation speed is 5 circles per minute, the current is 0.4A, the fan power is 90W, the current is 0.4A, the power of the blower 25 is 250W, the current is 0.7A, the operating voltage is 380V, the weight is 65 kg, and the coverage radius is 30 meters.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
