Description

Technical Field

[0001] This utility model belongs to the field of aerator technology, and specifically relates to a fishpond aerator. Background Technology

[0002] A fishpond aerator is a device specifically designed to increase the dissolved oxygen content in fishpond water, playing a crucial role in aquaculture. With increasing aquaculture density and stricter requirements for the aquaculture environment, the application of fishpond aerators is becoming increasingly widespread.

[0003] In existing technologies, three-phase permanent magnet synchronous motors are mainly used as drive devices in fishpond aerators. However, the manufacturing process of three-phase permanent magnet synchronous motors is more complex, and the use of high-performance permanent magnet materials increases costs. Furthermore, in order to achieve efficient operation, three-phase permanent magnet synchronous motors need to be equipped with dedicated drivers and controllers to precisely control their speed and position. In addition to the cost of the motor itself, additional investment is required in a complex electronic control system. Moreover, the high humidity and potential presence of corrosive substances in the fishpond environment can damage the motor.

[0004] Therefore, the use of three-phase permanent magnet synchronous motors is usually quite expensive, and the above situation urgently needs to be addressed. Utility Model Content

[0005] Purpose of the utility model: To overcome the above shortcomings, the purpose of this utility model is to provide a fishpond aerator to solve the problem of high manufacturing costs in existing technologies. By optimizing motor selection and overall structural design, the manufacturing and maintenance costs of the equipment are significantly reduced, thereby increasing the economic benefits for fish farmers.

[0006] Technical Solution: A fishpond aerator includes a drive system, a transmission mechanism, an aeration component, a connecting component, and a buoyancy device. The lower end of the drive system is connected to the transmission mechanism, the outer periphery of the transmission mechanism is provided with the connecting component, and the outer end of the connecting component is provided with the buoyancy device. The aeration component is installed at the bottom of the transmission mechanism. The drive system includes an outer casing, an outer rotor assembly, an inner stator assembly, a motor shaft, and a support assembly. The inner stator assembly is sleeved and fixed on the motor shaft, and its bottom is connected to the support assembly. The outer rotor assembly is sleeved on the motor shaft and surrounds the inner stator assembly. The outer casing is located on the outermost side of the drive system. This application, through reasonable optimization of motor selection and overall structural design, reduces unnecessary material consumption and processing complexity, thereby effectively reducing the production cost of the equipment and improving its market competitiveness.

[0007] Furthermore, the inner stator assembly includes an inner stator frame, magnetic poles, an inner stator core, and an excitation winding; the inner stator frame is mounted on a support assembly, the outer ring of the inner stator frame is fitted with the inner stator core, the outer side of the inner stator core forms the magnetic poles, and the inner stator core is provided with an excitation winding. This application adopts a modular, layered structure, with clear hierarchical relationships and standardized connections between components, which facilitates the inspection or replacement of specific components during later maintenance, reducing maintenance costs.

[0008] Furthermore, the excitation winding includes an excitation coil wound around the inner stator core to generate a rotating magnetic field. In this application, the excitation coil is directly wound around the inner stator core, effectively utilizing the principle of electromagnetic induction to generate a strong, uniformly distributed rotating magnetic field when energized. This helps improve the motor's conversion efficiency and output torque, ensuring the efficient operation of the aerator drive system.

[0009] Furthermore, an outer rotor assembly is arranged around the outer side of the magnetic poles. The outer rotor assembly includes permanent magnet poles and an outer rotor housing. The permanent magnet poles are arranged adjacent to each other around the outer side of the magnetic poles, and the outer rotor housing is wrapped around the permanent magnet poles. This application's outer rotor assembly uses a permanent magnet pole design, which, through interaction with the rotating magnetic field generated by the inner stator assembly, can achieve high-efficiency energy conversion. Because permanent magnets can provide a stable and strong magnetic field, the motor has higher efficiency and power density during operation.

[0010] Furthermore, the inner stator assembly includes at least 48 magnetic poles. The increased number of magnetic poles in this application provides more opportunities to generate torque pulses during each rotation cycle, thereby enabling higher starting torque and a smoother operating experience at low speeds.

[0011] Furthermore, the oxygenation component includes a fixed plate, a rotating wheel, and blades. The upper end of the fixed plate is connected to a transmission mechanism, and the lower end is fitted with the rotating wheel. Blades are evenly arranged around the outer wall of the rotating wheel. The outer side of the blades is bent, and the inner side is obliquely arranged on the outer wall of the rotating wheel. The bent outer side design of the blades in this application helps to more effectively agitate the water during rotation, increasing the contact area between the water and air, thereby improving oxygen dissolution efficiency. At the same time, the oblique inner side optimizes the water flow direction, enhances the mixing effect of the water flow, and further promotes oxygen diffusion.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0013] 1. This application relates to a fishpond aerator, which reduces unnecessary material consumption and processing complexity by reasonably optimizing motor selection and overall structural design, thereby effectively reducing the production cost of the equipment and improving its market competitiveness.

[0014] 2. This application relates to a fishpond aerator, in which the outer side of the blades is bent, which helps to more effectively agitate the water during rotation, increasing the contact area between the water and air, thereby improving oxygen dissolution efficiency. Simultaneously, the inclined inner side optimizes the water flow direction, enhances water mixing, and further promotes oxygen diffusion. Attached Figure Description

[0025] For further details, please refer to...

[0026] For further details, please refer to... Figure 3 As shown, the inner stator assembly 13 includes an inner stator frame 131, magnetic poles 132, an inner stator core 133, and an excitation winding 134. The inner stator frame 131 is mounted on the support assembly 15. The inner stator core 133 is sleeved on the outer ring of the inner stator frame 131. The outer side of the inner stator core 133 is the magnetic pole 132. The excitation winding 134 is provided on the inner stator core 133.

[0027] Furthermore, the excitation winding 134 includes an excitation coil wound around the inner stator core 133 to generate a rotating magnetic field.

[0028] Furthermore, the inner stator assembly 13 includes at least 48 magnetic poles 132.

[0029] For further details, please refer to... Figure 4 As shown, an outer rotor assembly 12 is arranged around the outside of the magnetic pole 132. The outer rotor assembly 12 includes a permanent magnet pole 121 and an outer rotor housing. The permanent magnet pole 121 is arranged adjacent to the outside of the magnetic pole 132, and the outer rotor housing is arranged to wrap around the permanent magnet pole 121.

[0030] For further details, please refer to... Figure 5 As shown, the oxygenation component 3 includes a fixed plate 31, a rotating wheel 32, and blades 33. The upper end of the fixed plate 31 is connected to the transmission mechanism 2, and the lower end is equipped with the rotating wheel 32. The blades 33 are evenly arranged around the outer wall of the rotating wheel 32. The outer side of the blades 33 is bent, and the inner side is obliquely arranged on the outer wall of the rotating wheel 32.

[0031] Furthermore, the outer bending angle of the blade 33 can be adaptively adjusted according to the usage scenario.

[0032] Furthermore, the working steps of a fishpond aerator include:

[0033] Step S1: Power On: The user connects the aerator to the power supply via the control switch, providing electrical energy to the drive system 1. At this time, the entire system's circuitry begins to operate, preparing to start the motor.

[0034] Step S2: Generating a rotating magnetic field: The inner stator assembly 13 in the drive system 1 starts to work, and the excitation winding 134 generates a rotating magnetic field on the inner stator core 133 after being energized.

[0035] The rotating magnetic field is generated by the current flowing in the excitation coil and interacting with the inner stator core 133.

[0036] Step S3: Rotation of outer rotor assembly 12

[0037] The generated rotating magnetic field interacts with the permanent magnet poles 121 on the outer rotor assembly 12, causing the outer rotor assembly 12 to start rotating.

[0038] Step S4: Power is transferred to oxygenation component 3

[0039] The rotational motion of the outer rotor assembly 12 is transmitted to the oxygenation assembly 3 through the transmission mechanism 2.

[0040] The transmission mechanism 2 ensures efficient and stable power transmission from the drive system 1 to the oxygenation component 3, enabling the oxygenation component 3 to operate at the designed speed and torque.

[0041] Step S5: Oxygenation component 3 begins operation.

[0042] The fixed plate 31 in the oxygenation assembly 3 transmits the power of the transmission mechanism 2 to the rotor 32, causing the rotor 32 to start rotating at high speed. The blades 33 mounted on the outer wall of the rotor 32 then move rapidly.

[0043] The outer side of blade 33 is bent, which helps to effectively agitate the water when rotating and increase the contact area between the water and the air.

[0044] The slanted design on the inner side of the blade 33 optimizes the direction of water flow, causing the water to be lifted and thrown out, promoting oxygen dissolution in the water, and driving water circulation.

[0045] Step S6: Achieve water oxygenation and circulation

[0046] The high-speed rotating blades 33 continuously bring oxygen-deficient water from the bottom to the surface, allowing it to fully contact the air and thus increasing the dissolved oxygen content in the water. At the same time, the movement of the blades 33 also promotes the mixing and circulation of the water throughout the fishpond, preventing water stratification and ensuring that oxygen is evenly distributed throughout the fishpond.

[0047] Step S7: Continuous monitoring and adjustment

[0048] Equipped with sensors to monitor water quality parameters such as dissolved oxygen in real time, and automatically adjust the working status of the aerator to maintain optimal water quality conditions, the specific sensor model and function configuration can be adaptively selected.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
