Accompanying drawing explanation
Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail, wherein:
Fig. 1 is wind power generation plant electric generator structure schematic diagram of the present invention;
Fig. 2 is wind power generation device structure schematic diagram of the present invention.
Embodiment
Refer to Fig. 1, the generator of wind power generation plant of the present invention comprises stator 1 and rotor 2, and wherein, stator 1 comprises main shaft 11 and is fixed on stator frame 12 formations on main shaft, is provided with the stator coil 121 that is planar alignment on stator frame 12.In this specific embodiment, stator coil 121 is embedded in stator frame 12.Stator frame 12 consists of the plastic cement of the parcel stator coil both sides that form at stator coil both sides casting plastic cement, and it adopts stator coil 12 is placed in to stator frame mould, and then in mould, the method for the both sides of stator coil casting plastic cement is made.Rotor 2 comprise on rotor, coil 21, rotor lower wall 22, rotor distance collar 23 and permanent magnet 24.On rotor, coil 21, rotor lower wall 22 and the common rotor disk that forms rotor of rotor distance collar 23.On stator coil 121, rotor, coil 21, rotor lower wall 22, rotor distance collar 23 and permanent magnet 24 all arrange axisymmetricly about main shaft 11.On rotor, coil 21 and rotor lower wall 22 by bearing 3, be rotatably connected on main shaft 11, and be positioned at the both sides of stator coil, thereby make stator coil be held on the inner side of described rotor.On rotor 2, be connected with fan blade, thereby fan blade rotates and drives described rotor under wind action.Rotor distance collar 23 is for determining the spacing between dish and rotor lower wall on rotor, and it is connected on rotor between dish and rotor lower wall and is positioned at the periphery of dish and rotor lower wall on rotor.Permanent magnet 24 is fixed on rotor the inner side of dish and rotor lower wall, and to clamp stator coil, thereby when rotor, permanent magnet rotation makes stator coil cutting magnetic line generation electric energy.For preventing that bearing and rotor are in the motion of main shaft axial direction, bearing 3 is clamped on main shaft 11 by clamp nut 4.
For reducing the loss of copper cash under high frequency, stator coil 121 adopts the mode of parallel winding of multiple coils to make, and it is different from the coil of traditional solid wire coiling.The stator coil that adopts parallel winding of multiple coils of the present invention to make, can be under same cross-sectional be long-pending, greatly reduce the loss of copper cash under high frequency, thereby by reducing the copper loss (high frequency skin effect) of coil, reach the temperature of reduction stator coil, the object of raising generating efficiency.The stator coil that adopts parallel winding of multiple coils of the present invention to make is compared the stator coil of traditional solid wire coiling, under equal rotating speed, cutting magnetic field conductor number is maximum, and induced electromotive force is maximum, is therefore more suitable for slow-speed of revolution Blast Furnace Top Gas Recovery Turbine Unit (TRT) (or breeze generating set).
For rotor can also can be rotated in the situation that being subject to low-force, in the situation of gentle breeze, spy adopts bearing unlubricated, nonmagnetic, low inertia by bearing 3, to realize less rotation friction, is conducive to realize breeze start-up and improves generating efficiency.
In order to explain more intuitively the present invention, adopt the advantage of the coil of the relatively traditional single line coiling of parallel winding of multiple coils stator coil, special being listed as follows:
| Coil modes of emplacement | Stator disc thickness | Designated diameter lower coil is placed number | Magnetic flux density | Cutting magnetic field conductor number |
| Vertical pile | Thick | More | Low | Many |
| Keep flat | Thin | Few | High | Few |
| Parallel winding of multiple coils | Thin | At most | High | At most |
Refer to Fig. 2, wind power generation plant 8 of the present invention comprises generator 81 and is connected in the fan blade 82 on generator amature 2, and fan blade 82 rotates under wind-force effect, thereby drives the rotor 2 of generator 81 to rotate, and stator coil cutting magnetic line produces electric energy.For strengthening the startup ability of fan blade 82 under gentle breeze environment, fan blade 82 is designed to comprise three blades 821 and three cup type fan blades 822 that are interspersed with three blades 821, three cup type fan blades 822 are designed to along same clockwise opening, as are counterclockwise or clockwise direction opening.Owing to having increased by three cup type fan blades 822 on the basis of traditional fan blade, when having wind, the design of cup type fan blade is more easily gone for a drive, thereby make whole fan blade compare traditional fan blade under same wind-force effect, more easily rotates, and is more conducive to the rotation of starter-generator mover.Fan blade area when increasing by three cup type fan blades 822 simultaneously and also having increased normal rotation, makes under same wind-force effect, and fan blade 82 is stressed larger, and rotary speed is faster, thereby generating efficiency is higher.
Please also refer to Fig. 1 and Fig. 2, wind power generation plant specific works principle of the present invention is as follows: owing to accepting the fan blade 82 of rotational energy, be arranged on by coiling 21 on rotor, on the rotor 2 that rotor lower wall 22 and rotor distance collar 23 form, fan blade 82 rotates under wind action, thereby rotor driven disc spins, be fixed on the N utmost point on rotor disk, the extremely staggered permanent magnet 24 of S rotates with rotor disk, because stator coil 121 and main shaft 11 maintain static, thereby between stator and rotor, produce the relative motion of cutting magnetic line, finally in electronic coil, produce electromotive force.
Wind power generation plant of the present invention can apply to the Blast Furnace Top Gas Recovery Turbine Unit (TRT) below power 3000W, innovative design due to structure, realized breeze start-up (wind speed of 1 meter per second), field of employment than traditional wind-driven generator is wider, can also be used in the occasion of the multiple gentle breezes such as various families roof, urban road.
