DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Now, the present invention will be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
Firstly, with reference to FIG. 1 through FIG. 4 illustrating preferred embodiments of an environmental energy-saving power generator 100 according to this invention, the environmental energy-saving power generator 100 is connected to several loads 200, supplies power to the loads 200, and lengthen the operation time of the loads 200, and can also be connected to an external AC power 300 for charging. The environmental energy-saving power generator 100 mainly comprises a power generation module 10, a control module 20, a power module 30, a power generator housing 40, and an I/O module 50.
The power generation module 10 comprises two generator units 11 and a drive unit 12. Each power generator unit 11 further comprises a power generation stator 111, a housing 112, and a power generation rotor 113. The power generation stator 111 is formed with silicon steel plates that are superimposed, outside which several power generation magnetic poles 114 are formed. Several power generation magnetic-pole coils 115 are formed wrapping around the power generation magnetic poles 114. A shaft 13 is provided axially pivoting around the center of power generation stator 111. The power generation rotor 113 is concentrically mounted onto the shaft 13, the power generation stator 111 is housed in the power generation rotor 113, and when running, the power generation rotor 113 structured with a multi-pole permanent magnet 113 can cut the magnetic lines of force caused by the power generation magnetic-pole coils of the power generation stator 111 to generate power, and thus the power generator unit 11 is made to convert magnetic energy into electric energy. The power generator units 11 are separately provided at two sides of the shaft 13 and, with reference to FIG. 3, the power generation rotor 113 is provided with several axial heat dissipation holes 116. Heat dissipation blades 117 are each formed between the heat dissipation holes 116 each of which stretches. The heat dissipation blades 117 are combined with the power generation rotor 113 in one. Further, the circumference of power generation rotor 113 is covered by the housing 112. The housing 112 is axially formed with several thru holes 118. The thru holes 118 are opposite to the heat dissipation holes 116 and the heat dissipation blades 117. Thus, heat energy generated by the operating power generator unit 11 is vented out. With reference to FIG. 2, the drive unit 12 coaxially pivots on the shaft 13 and lies between the power generator units 11. The drive unit 12 further comprises a housing 121, a multi-pole drive rotor 122, and a drive stator 124 provided with several drive magnetic-pole coils 123. The multi-pole drive rotor 122 is coaxially mounted onto the shaft 13 of the power generator unit 11. The drive stator 124 co-axially pivots around the outer circumference of multi-pole drive rotor 122, making the drive stator 124 drive the multi-pole drive rotor 124 by means of the magnetic lines of force that are caused by the drive magnetic-pole coils 123. The housing 121 wraps around the outer circumference of drive stator 124 for tight fixing. In a preferred embodiment of this invention, the drive unit 12 is further a DC brushless motor and a drive controller driving the DC brushless motor. The drive unit can be connected to an AC motor.
Again with reference to FIGS. 1 and 4, the control module 20 is connected to the power generation module 10 for operation control and is further electrically connected through a power management unit 21 to a processor unit 22, a charging unit 23, and a protective unit 24. The processor unit 22 is used to mainly control the power management unit 21, driving the power management unit 21 to manage the electric energy consumed and generated by the environmental energy-saving power generator 100. The processor unit 22 is connected to control an alarm unit 25 so that the processor unit 22 can send an alarm signal when receiving an abnormal signal transmitted by the power management unit 21. In the preferred embodiment of this invention, the alarm unit 25 is an annunciator that is a warning lamp or a buzzer. Further, the protective unit 24 is used to detect whether the electrical loop of environmental energy-saving power generator 100, when operating, is abnormal, and send the detection result back to the power management unit 21. In the preferred embodiment of this invention, the protective unit 24 is a temperature sensor.
The power module 30 comprises a battery 31. The power module 30 is connected to the power management unit 21 of control module 20 to supply electric power to the power management unit 21, and to the charging unit 23 to store the electric power allocated and supplied by the power management unit 21 in the power module 30.
The power generator housing 40 can house the power module 30, the control module 20, and the power module 10.
The I/O module 50 is provided in the power generator housing 40 and is made up with an output unit 51 and an input unit 52 that are electrically connected to the power management unit 21, in which the output unit 51 is connected to the loads 200 and the input unit 52 is connected to an input terminal of another external AC power 300.
With reference to FIGS. 1 and 2, in the environmental energy-saving power generator 100, the power module 30 supplies power to the drive unit 12 of power generation module 10 so as to make the drive unit 12 drive the connected power generator unit 11; thus, the drive magnetic-pole coils 123 on the drive stator 124 of drive unit 12 is made to generate the magnetic lines of force, and with the variation of sine-wave frequency, the polarity caused by the drive magnetic-pole coils 123 varies to make the multi-polarity drive rotor 122 sense the variation of magnetic lines of force of drive stator 124, thereby the multi-polarity drive rotor 122 being made to correspondingly run. The multi-polarity drive rotor 122 synchronously has the shaft 13 run arranged in the central axis. The shaft 13 turns the power generation rotors 113 of the power generator unit 11 that are arranged at two sides of the drive unit 12. When the power generation rotors 113 run, because the magnetic lines of force cut the power generation stators 111, the power generation magnetic-pole coils 115 of the power generation stators 111 are made to generate induction current; thus, the power generator units 11 are made to supply the power to the load 200 of power generator unit 11. When the power generator unit 11 supplies excessive power, the power management unit 21 of control module 20 re-charges the battery 31 of power module 30 with the surplus power through the charging unit 23. Further, with reference to FIG. 1, when the power of power module 30 of the environmental energy-saving power generator 100 is not enough, an external AC power 300 can be connected, and the power management unit 21 re-charges the battery 31 of power module 30 with the power supplied by the AC power source 300 through the charging unit 23.
With reference to FIG. 5 illustrating another embodiment of this invention, the major structure and effect of environmental energy-saving power generator 100 is the same as that in the previous preferred embodiment, so unnecessary details are not given here. The drive unit 12 is further connected to a speed change device 400. The speed change device 400 is connected to a power wheel 401 driving the power wheel 401 to turn the drive rotor 122 and the shaft 13 and driving the power generation rotor 113 to run. Thus, when the power wheel 401 runs, the power generator unit 11 may be driven to generate power.
