Description

Technical Field

[0001] The utility model relates to the technical field of spoiler equipment, in particular to a spoiler equipment with non-contact power output. Background Art

[0002] Turbulence refers to the random fluctuation of particles in the fluid caused by the continuous generation and destruction of eddies during unsteady flow. Turbulence can increase the turbulence intensity and turbulence energy in the fluid, improve the distribution of fluid components, and thus promote the convection and diffusion of substances. Turbulence can also push suspended materials to the surface of the fluid, making it easier for them to transfer and react with the surrounding environment.

[0003] Existing flow disturbance devices generally include a casing, a motor, a rotating shaft and blades. The motor drives the rotating shaft to rotate, and the blades are fixed on the rotating shaft. The rotation of the blades causes disturbances to the fluid. The existing motor is directly connected to the rotating shaft, and the flow disturbance device as a whole needs to be fixed inside the fluid container. Since the motor is prone to heat up during operation and may have risks such as leakage, it is easy to have adverse effects on the fluid. Utility Model Content

[0008] Furthermore, the spoiler unit also includes a plurality of bearings, and the first permanent magnet is rotatably connected to the rotating shaft through the plurality of bearings.

[0009] Furthermore, the power generation unit also includes a fixing frame, which is fixed to the inner side of the upper cover, and the edge of the fixing frame is located outside the second permanent magnet to limit the second permanent magnet.

[0010] The beneficial effects of this solution are as follows: (1) This solution includes two parts, a spoiler unit and a power generating unit, which are coupled by two permanent magnets. The spoiler unit is placed inside the fluid container to perform spoiler flow, and the power generating unit provides power to the spoiler unit outside the fluid container through two coupled permanent magnets, thereby realizing non-contact power output.

That is, this solution does not require a magnetic coupling, has significantly fewer components, a simpler structure, a smaller size, and a lower cost. BRIEF DESCRIPTION OF THE DRAWINGS

The second permanent magnet 12 is rotatably connected in the annular groove 15 through the three bearings 5, wherein the two bearings 5 ​​located at the upper end and the lower end of the second permanent magnet 12 are deep groove ball flange bearings 5, and the fixing frame 13 is fixed on the inner side of the upper cover, and the edge of the fixing frame 13 is located on the outer side of the second permanent magnet 12 to limit the second permanent magnet 12, and the second permanent magnet 12 is radially magnetized (cross magnetization, 4-pole magnetization or multi-stage magnetization can also be used), and six coil grooves 16 that are evenly arranged and symmetrical in the circumferential direction are provided on the outer side of the annular groove 15, and six coil windings 11 are placed in the coil grooves 16, and every two symmetrical coil windings 1 1 is a group, 3 groups of coil windings 11 are driven by 3 MOS half-bridge circuits, 3 groups of coil windings 11 are connected to the controller and controlled by the controller, the magnetic field intensity sensor is installed on the fixed frame 13, and the line connecting the two magnetic field intensity sensors and the center point of the annular groove 15 is perpendicular to each other, the magnetic field intensity sensor uses the HX6659-D chip or the same type of linear Hall intensity sensor, because the N pole and S pole of the permanent magnet are distributed on both sides of the radial direction of the second permanent magnet 12, the magnetic field intensity is large at the point where N and S are distributed, and the magnetic field intensity at the point where N and S intersect is about 0; when the second permanent magnet 12 rotates, for a fixed position, the change of its magnetic field intensity is a sinusoidal change, and the period of the waveform is equal to the period of rotation of the magnet. The function of the linear Hall intensity sensor is to detect the magnetic field intensity and convert the magnetic field intensity into a voltage amplitude, so the voltage output by the two linear Hall intensity sensors with respect to time should be two orthogonal sinusoidal function waveforms. After normalizing the two orthogonal sinusoidal function waveforms, the inverse sine function is used to take the solution when the inverse sine function angle values ​​of the two sinusoidal functions differ by π / 2, and the current rotor phase can be obtained. The upper cover 14 is fixed to the base 10, and the first permanent magnet and the second permanent magnet 12 are coupled.
