Technical Field

[0001] The utility model relates to the technical field of oxygenators, in particular to an automatic speed-regulating variable-frequency oxygenator. Background Art

[0002] Aerator is a machine commonly used in fish farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be deprived of oxygen. It can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pond water from threatening the living environment of the fish. Aerators generally rely on their own air pump to pump air into the water to achieve the purpose of increasing the oxygen content in the water.

[0003] The gears of aerators currently on the market are generally divided into three gears, which are switched by continuously turning the power switch on and off. Manual operation is required when switching the gears, and it cannot adapt to more oxygenation environments. When more aerators are set up, users are required to operate them one by one, and the operation efficiency is low. Based on this, a variable frequency aerator with automatic speed regulation is proposed to solve the above problems. Utility Model Content

A connecting rope 6 is installed at the bottom end of the barrel 9, and a counterweight 7 is installed at the bottom end of the three. The control module 13 includes multiple IGBT modules, which are electrically connected to the three dissolved oxygen meters 8 respectively. The dissolved oxygen meter 8 measures the decrease in the dissolved oxygen content in the water and sends a signal to the corresponding IGBT module, thereby controlling the number of the three IGBT modules working, thereby increasing the output power, increasing the speed of the motor inside the aerator body 1, and realizing automatic control of the speed. At the same time, the control module 13 also includes an ARM processor for signal processing, a circuit board with a power supply circuit and a control circuit, the ARM processor is used to process and convert data, the power supply circuit provides power support for the ARM processor, and the control circuit controls the IGBT module, the reduction motor 3 and the drive motor 14 respectively.

[0023] The annular rod 2 is arranged at a circumferential position of the aerator body 1, and fixed frames 10 are installed on three sides of the annular rod 2 away from the mounting rod 11. The bottom walls of the three fixed frames 10 are installed with reduction motors 3, and the output ends of the three are respectively fixedly connected to the three guide pipes 4. As an optional technical solution of the utility model, it is convenient to install the three guide pipes 4 circumferentially around the aerator body 1. By energizing the reduction motor 3, the three guide pipes 4 are driven to swing at a certain angle respectively, so as to push the water with high dissolved oxygen to a distant place, so as to increase the overall dissolved oxygen content of the fish pond.

[0024] The three reduction motors 3 are electrically connected to the control module 13 through wires. As an optional technical solution of the present invention, the three reduction motors 3 are integrated with a reduction gear structure to reduce the rotation speed of the guide tube 4 and increase the output torque, so as to drive the guide tube 4 to oscillate in a certain angle and adjust the direction of water outflow.

[0029] 2) When the dissolved oxygen content is low, a control signal is sent to the control module 13;

[0030] 3) The control module 13 increases the output power and speeds up the rotation speed of the aerator body 1 .

[0031] In summary, when the user uses it, the aerator body 1 is arranged to float on the water surface, and the three dissolved oxygen meters 8 are respectively arranged around the aerator body 1 and electrically connected to the control module 13 through wires. At the same time, the annular rod 2 is installed around the aerator body 1, and the three sides of its outer wall are equipped with a reduction motor 3, a guide tube 4, a drive motor 14 and a rotating blade 12. The drive motor 14 is powered on to drive the rotating blade 12 to rotate, so that the water around the aerator body 1 is sent to a distant place. At the same time, the dissolved oxygen meter 8 measures the dissolved oxygen in the water. When the dissolved oxygen is low, it sends a signal to the control module 13. Block 13 sends a control signal, and the control module increases the output power, which is used to control the aerator body 1 to rotate faster, thereby controlling the speed of the aerator body 1, realizing automatic adaptive adjustment, saving the user's labor, and facilitating promotion and use. Then, three fixed frames 10 are set, and reduction motors 3 are installed inside the three frames.
