The main shaft 30 passes through the seal cavity 80 in a sealing way, namely, after the main shaft 30 passes through the seal cavity 80, the seal cavity 80 still keeps sealing.
The embodiment of the present invention has the beneficial effect that, compared with the prior art, the high magnetic energy ac/dc generator 100 with multiple sets of series-connected power generation mechanisms provided in the embodiment of the present invention includes at least two sets of power generation mechanisms 40 which are connected in series and then accommodated in a sealed cavity 80, the main shaft 30 passes through the sealed cavity 80 in a sealed manner, and when the main shaft 30 is driven by the driving mechanism 20 to rotate, the power generation mechanisms 40 are driven by the main shaft 30 to rotate relative to the sealed cavity 80, so as to generate power by the power generation mechanisms 40. The axial design of the power generation mechanism 40 along the main shaft 30 is equivalent, the volume occupied in the radial direction of the main shaft 30 is reduced, the structure is simpler, the production cost is saved, and the output power of the high-magnetic-energy alternating current and direct current generator 100 with multiple groups of power generation mechanisms connected in series and the same diameter is improved. The power generation mechanism 40 comprises a power generation magnetic block formed by embedding the magnet into the iron rare earth silicon block, and the power generation magnetic block formed by embedding the magnet into the iron rare earth silicon block can improve the electric energy output of the electromagnetic reaction of the power generation mechanism 40 by utilizing the high magnetic energy characteristic of the power generation magnetic block.
The drive mechanism 20 may be designed as an inner stator and outer rotor configuration, such as with the stator and coils of the drive mechanism 20 on the inside and the rotor and drive magnet blocks 26 on the outside. Alternatively, the stator of the driving mechanism 20 is the driving magnet block 26 and is disposed outside, and the coil is the rotor outside the driving mechanism 20.
The power generating mechanism 40 may be designed as an inner rotor outer stator, for example, the stator and the coil of the power generating mechanism 40 are on the outside, and the power generating rotor 41 is a power generating magnetic block on the inside. Or the stator of the power generation mechanism 40 is a magnetic block and is arranged on the outer side, the coil is used as the power generation rotor 41 and is arranged on the inner side of the power generation mechanism 40, the main shaft 30 rotates to drive the coil to rotate, and the wire of the coil can be arranged in the main shaft 30.
In another embodiment, as shown in fig. 1, a high magnetic energy ac/dc generator 100 with multiple sets of series-connected generating mechanisms comprises a support 10, a driving mechanism 20, a main shaft 30 and at least two sets of generating mechanisms 40.
The driving mechanism 10 comprises a driving stator 22, a driving coil 24, a driving magnetic block 26 consisting of iron-rare earth-silicon blocks embedded with magnets and a driving rotor 28; the driving stator 22 is fixed on the bracket 10; the driving coils 24 are sleeved at two ends of the driving stator 22 and fixed with the driving stator 22; the driving magnetic block 26 is rotatably connected with the bracket 10, and the driving magnetic block 26 is positioned on one side of the driving stator 22 far away from the driving coil 24; the driving rotor 28 is sleeved on the outer side of the driving magnetic block 26 and fixed with the driving magnetic block 26.
The main shaft 30 is rotatably connected with the bracket 10; in particular, the main shaft 30 is rotatably connected with the stand 10 by means of a bearing 31 or a collar. Further, one end of the main shaft 30 protrudes out of the connection portion 32 to be fixed to the driving rotor 28.
The power generation mechanism 40 comprises a power generation rotor 41 consisting of a magnet embedded iron rare earth silicon block, a power generation stator 43 and a power generation coil 45; the power generation rotor 41 is fixed on the main shaft 30; the power generation stator 43 is fixed on the bracket 10 and positioned outside the power generation rotor 41; the generating coil 45 is sleeved on two ends of the generating stator 43 and fixed with the generating stator 43. The driving rotor 28 of the driving mechanism 20 drives the main shaft 30 to rotate, the main shaft 30 drives the power generation rotor 41 of the power generation mechanism 40 to rotate, the power generation rotor 41 is installed on the same axial direction of the main shaft 30, which is equivalent to designing the main magnetic field generated by the power generation rotor 41 in the radial direction of the main shaft, and the influence of the diamagnetic field generated in the power generation process of the power generation coil 45 of the power generation mechanism 40 on the main magnetic field can be reduced.
Specifically, the power generation rotor 41 includes a plurality of first magnetic blocks arranged at intervals in the radial direction of the main shaft 30, and the first magnetic blocks are composed of iron-rare earth-silicon blocks with magnets embedded therein. Of course, the first magnetic blocks arranged at intervals may also be arranged uniformly or non-uniformly in the radial direction of the main shaft 30.

Of course, the second magnetic blocks arranged at intervals may also be arranged uniformly or non-uniformly in the radial direction of the main shaft 30. The first magnetic blocks and the second magnetic blocks are arranged in a staggered mode, so that mutual influence of magnetic fields between adjacent power generation mechanisms 40 can be reduced and even avoided. For example, the number of the first magnetic blocks is four, and the four first magnetic blocks are respectively arranged between 0-45 degrees, 90-135 degrees, 180-315 degrees and 270-135 degrees of the outer cylindrical surface of the main shaft 30; the number of the second magnetic blocks is four, and the four second magnetic blocks are respectively arranged between the outer cylindrical surface of the main shaft 30 at 45-90 degrees, 135-180 degrees, 225-270 degrees and 315-360 degrees. Of course, other numbers and arrangements of the first magnetic blocks and the second magnetic blocks can be designed, as long as the first magnetic blocks and the second magnetic blocks are arranged in a staggered manner. Regardless of whether the first magnetic block and the second magnetic block have like magnetic poles adjacent to each other or opposite magnetic poles adjacent to each other, the first magnetic block and the second magnetic block are arranged in a staggered manner and are uniformly distributed on the outer cylindrical surface of the spindle 30, but the first magnetic block and the second magnetic block are not overlapped on the outer cylindrical surface of the spindle 30 in the axial direction of the spindle, so that magnetic fields between adjacent power generation mechanisms 40 cannot influence each other, and thus a plurality of groups of power generation mechanisms 40 can be arranged in the axial direction of the spindle 30. Also, since the magnetic fields between adjacent power generation mechanisms 40 do not affect each other, compared with the resistance of like-pole repulsion or opposite-pole attraction between the magnetic fields between adjacent power generation mechanisms in the related art, it is difficult to drive the rotors of the power generation mechanisms, in the embodiment of the present invention, the power generation rotors of multiple sets of power generation mechanisms 40 can be driven to rotate without too much driving force, and the power generation efficiency of the high magnetic energy ac/dc generator 100 with multiple sets of power generation mechanisms connected in series is improved.

Specifically, the surface of the magnetic shield layer 48 may be coated with a magnetic shield material. The gap between two adjacent sets of power generation mechanisms 40 can also be enlarged. For example, a magnetism isolating layer 48 is provided between two adjacent sets of generating coils 45, or two adjacent sets of generating coils 45 have a predetermined gap; a magnetism isolating layer 48 is provided between the adjacent two sets of the power generating rotors 43, or the adjacent two sets of the power generating rotors 43 have a predetermined gap.

Specifically, in order to prevent the adjacent power generation mechanisms 40 from interfering with each other, a first gap 42 or a first magnetism isolating sheet (not shown) is provided between the adjacent power generation rotors 41, and a second gap 44 or a second magnetism isolating sheet (not shown) is provided between the adjacent power generation coils 45.
Further, one or more of the driving stator 22, the driving magnet block 26, the driving rotor 28, the generating rotor 41 and the generating stator 43 is composed of a magnet embedded in a ferro rare earth silicon block, and the magnet and the ferro rare earth silicon block are combined according to a certain proportion. For example, at least the driving magnet block 26 and the power generating rotor 41 are each designed to be composed of a magnet-embedded iron rare earth silicon block, and in the present embodiment, the power generating rotor 41 is also a power generating magnet block.

The power generation rotor 41 utilizes the characteristics of a permanent magnet magnetic material made of iron, rare earth and silicon, and according to the attraction torque generated by the permanent magnetic field of the power generation rotor 41 and the electromagnetic torque generated by the electromagnetic field of the power generation coil 45, the attraction force of the permanent magnetic field at a certain position is overcome by utilizing the permanent magnetic field to reduce the resistance required to be overcome by the electromagnetic field, so as to achieve magnetic balance, and meanwhile, the electromagnetic field and the permanent magnetic field generate electric energy under the action of different torques through the electric control system 50.

As shown in fig. 3, the heat absorbing blind holes 46 are disposed in the holder 10 in the most part and in the power generating stator 43 in a small part to avoid occupying too much the volume of the power generating stator 43. When the high-magnetic-energy alternating current-direct current generator 100 with multiple sets of series-connected generating mechanisms is in use, the temperature of the generating stator 43 rises, and the heat absorption blind holes 46 also help to reduce the temperature of the generating stator 43.

The air duct 11 can assist the heat sink blind holes 46 in dissipating heat. The intermittent motion mechanism can be set as one of a ratchet mechanism, a geneva mechanism, a link mechanism or an incomplete gear mechanism, and is also connected with a servo motor which controls the intermittent motion mechanism to drive the third magnetism isolating sheet 112 to open or close periodically. The electric control system 50 controls the servo motor through a Programmable Logic Controller (PLC), and the power supply portion 60 supplies power to the servo motor.
Preferably, in order to provide a better heat dissipation effect, the outer surface of the power generation stator 43 may be covered with a heat conductive paste, which may further improve the sensitivity during power generation.
As shown in fig. 1, when the driving magnetic block 26 at the upper position is close to the top driving coil 24, the direction of the magnetic field generated by energizing the driving coil 24 is opposite to the direction of the magnetic field generated by the driving magnetic block 26 (for example, the N-level of the driving coil 24 faces the center of a circle and the N-level of the driving magnetic block 26 faces the outside of the circle, or the N-level of the driving coil 24 faces the outside of the circle and the N-level of the driving magnetic block 26 faces the center of the circle), so that a repulsive force exists between the driving magnetic block 26 and the driving coil 24, and the driving coil 24 pushes the driving magnetic block 26 to rotate. When the driving magnetic block 26 rotates to a certain angle, for example, in this embodiment, after approaching 180 degrees, when the same driving magnetic block 26 is close to the next driving coil 24, the repulsive force between the same poles becomes the resistance to the rotation of the driving magnetic block 26, at this time, the driving coil 24 needs to be powered off, because of the power off, the magnetic field of the driving coil 24 will disappear, the driving magnetic block 26 continues to move due to inertia, when the same driving magnetic block 26 passes through another driving coil 24, the driving coil 24 continues to be powered on, at this time, the repulsive force between the same poles existing between the driving coil 24 and the driving magnetic block 26 will actuate the driving magnetic block 26 to continue to rotate, and thus, the purpose of driving the spindle to rotate is achieved.
