Embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates by reference to the accompanying drawings.
The power-actuated digital frequency conversion double-generator of single action of the present invention group comprises double-generator main machine frame, frequency converter, unit frame, as shown in Figure 1, the double-generator main machine frame comprises combustion power machine 4, left generator 5, right generator 2, left wind scooper 6, right wind scooper 3 and right cooling fan 1, left side generator 5 and left wind scooper 6 are positioned at the left side of combustion power machine 4, and right cooling fan 1, right generator 2 and right wind scooper 3 are positioned at the right side of combustion power machine 4.Right wind scooper 3 is connected with combustion power machine 4 with the seam ways of connecting, and right generator 2 and right cooling fan 1 are installed in the cavity of right wind scooper 3, and left generator 5 is positioned at a cavity of left wind scooper 6.Right generator 2 comprises right generator amature 21 and right generator unit stator 22, and right wind scooper 3 comprises right wind scooper sidewall air outlet 31, and combustion power machine 4 comprises bent axle 41 and combustion power machine body 42.Left side generator 5 comprises flywheel rotor 52 and stator 51.Stator 51 links to each other with combustion power machine body 42 with the seam ways of connecting, and flywheel rotor 52 is fixed on the bent axle 41 and with bent axle 41 in the mode of taper fit and rotates synchronously.As shown in Figure 2, flywheel rotor 52 is made up of flywheel body 7, magnet steel skeleton 8, rotor magnetic steel 9 and triggering magnet steel 10, and the wheel rotor is not only made flywheel but also play the rotor effect, so just makes the compact conformation of the power-actuated digital frequency conversion double-generator of single action group.Rotor magnetic steel 9 comprises eight pairs of magnetic poles (two corresponding a pair of magnetic poles of magnet steel, 2 * 8=16 sheet magnet steel), bonding a pair of magnetic pole in each draw-in groove of magnet steel skeleton 8 (two magnet steel just).Magnet steel skeleton 8 is assemblied in the intracavity bottom of flywheel rotor 52, and the outer wall of rotor magnetic steel 9 is close to the inwall of flywheel body 7, triggers the outer wall that magnet steel 10 is fixedly installed in flywheel body 7.
As shown in Figure 3, the structure of right wind scooper 3 is the off-centre operation structure.As shown in Figure 4 and Figure 5, frequency converter comprises the first frequency converter split 11 and the second frequency converter split 12.When right generator amature 21 rotates with bent axle 41, right cooling fan 1 stirs air-flow and moves counterclockwise, under the guiding of right wind scooper 3 eccentric object lines, A-A section in Fig. 3 begins to occur draught head, draught head causes that gas flow increases in the counterclockwise direction gradually between the folder chamber of right generator amature 21 and right wind scooper 3, thereby make right wind scooper sidewall air outlet 31 have enough air outputs to cool off the first frequency converter split 11, i.e. the first frequency converter split 11 is relative with right wind scooper sidewall air outlet 31.The first frequency converter split 11 is fixed on the unit frame 13, and makes the windward side of the first frequency converter split 11 become non-parallel angle to install with the plane of right wind scooper sidewall air outlet 31.The first frequency converter split 11 has radiating ribs, radiating ribs be shaped as herringbone, radiating ribs is towards right wind scooper sidewall air outlet 31, like this when right cooling fan 1 stirs air-flow and blows to the first frequency converter split 11 from the sidewall of right wind scooper 3, air-flow is (as shown in Figure 6) under the water conservancy diversion of radiating ribs, the fully cooling first frequency converter split 11 makes the first frequency converter split 11 be able to reliable and stable work.One end of the second frequency converter split 12 directly links to each other with combustion power machine body 42 by bolt, and the other end links to each other with right wind scooper 3 by contiguous block, so just the second frequency converter split 12 is fixed on the top of combustion power machine body 42.When 4 runnings of combustion power machine, the flywheel rotor 52 of band flabellum is with bent axle 4 rotations, the air stream that stirs cools off right generator 2 by the air-vent of flywheel rotor 52 ends on the one hand, another part is via the folder chamber of 52 of left wind scooper 6 and flywheel rotors, blow to the cylinder head of the second frequency converter split 12 and combustion power machine 4, the second frequency converter split 12 is sufficiently cooled.
As shown in Figure 7, double-generator digital frequency conversion device among the present invention is imported electric regulation and control system processed simultaneously with the signal of telecommunication of a plurality of motors, utilize electric regulation and control system processed to make voltage, frequency, electric current, the power of each motor synchronous, utilize control circuit that each motor is independent of each other then, and make each motor not influenced by output voltage, frequency, electric current, power etc.Control circuit makes the in parallel and independent control of a plurality of motor rectifications, the signal such as voltage, circuit of getting each motor compares, detects, and make the controllable silicon phase shifting control, make output equate in parallel, and by electricity regulation and control system processed each motor be can work independently, each is unaffected, and guarantees that the output of each motor reaches maximum.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these execution modes.Therefore, protection scope of the present invention is limited by appended claims.
