Description
The invention belongs to the dynamic power machine field:
Piston-engined power transmission mode has at present:
1, the mechanical way of output, generally with the connecting rod outputting power, minority directly with the piston outputting power, as pile driver, tamper etc. and the rotary piston engine of widespread usage not as yet.
2, with the way of output of gas medium, as free piston type gas compression unit etc.
3, with liquid be the way of output of medium, as Humphrey gas pump, free-piston oil hydraulic pump unit.
4, be converted to the electric power way of output, be " double-action free-piston---the generator set " among the patent ZL9122478.9, this patent gives " double-action free-piston---air compressor unit and gas turbine group ", this patent is higher more than 1 times than the frequency of okperation and the output power of common free piston installation, compacter gently little, but adjusting, starting, the complicated defective of injection system such as common free piston installation still exist, simultaneously, its air valve system has limited the further high speed of free piston installation high powerization.
The objective of the invention is: create a kind of band turbosupercharging opposed pistons device, promote the rocking arm reciprocally swinging, with gas, liquid or form of power outputting power, abundant advantage in conjunction with common opposed piston engine and free piston installation, overcome the two shortcoming, become the novel swing type power of class set.
The total feature of the present invention is: opposed pistons swing type power unit is made up of opposed pistons oscillating engine, swing type generator and turbine device.Fig. 1 is the mechanism of opposed pistons oscillating engine and turbine device among the present invention.Among the figure: 1-rocking arm, 2-piston rod, 3-power piston, 4-1-lower cylinder group, 4-2-upper cylinder group, 5-cylinder intake duct, the 6-wrist pin, 7-air inlet pipeline, 8-oil injecting nozzle, 9 bent axles, 10-turbosupercharger, 11-inblock cylinder air flue, the 12-turbine, 13-body, 14-rocking arm Xiao, the 15-connecting rod, 16-pitman arm shaft, 17-connecting rod Xiao.
The entire mechanism symmetric arrangement is characterized in that motor tandem plurality of rows, every row's twin-tub, and promptly the 4-1 upper cylinder is parallel with the 4-2 lower cylinder.Two opposed pistonss 3 link to each other with piston Xiao 6, piston rod 2, rocking arm Xiao 14, rocking arm 1 connecting rod 15, bent axle 9 respectively in every cylinder.Form the piston lazy-tongs, and drive each annex of motor and be used for ato unit.
The piston lazy-tongs of above-mentioned symmetry make two relative reversing motions of piston in every cylinder.The power of combustion gas expansion on power piston 3 in the cylinder is by rocking arm 1 swing on piston Xiao 6, piston rod 2, drive both sides.The reciprocally swinging of rocking arm promotes bent axle 9 rotations by connecting rod Xiao 17 connecting rods 15 on the one hand.During running, two cylinder alternate combustion expansion workings.When one cylinder oil injecting nozzle, 8 oil jetting combustions expanded, another cylinder was taken a breath.Realize direct current two stroke ventilation cycle, its working procedure is identical with common opposed pistons with principle.
Fig. 2 is the connecting of turbine device and opposed pistons oscillating engine cylinder block in the power unit of the present invention, i.e. A-A section among Fig. 1.Part is identical with label among Fig. 1 among the figure.It is characterized in that turbine device is right after cylinder block, waste gas is from cylinder 4-1, and the vent 11 of 4-2 directly enters the turbine of turbosupercharger 10.Realize (what common two-stroke engine was difficult to realize) pure turbosupercharging, pressurized air enters cylinder (Fig. 1) by air inlet pipeline 7, cylinder intake duct 5, thereby improves its power character and Economy.
Fig. 3 is the mechanism of swing type generator in the power unit of the present invention.Identical among the figure with the part of same label among Fig. 1, the part of other labels: 18-inner stator, 19-rotor, the 20-external stator, 21-stator yoke field winding, 22-inner stator jib, the drive sleeve of 23-tape insulation, the 24-generator body, 25-brush, 26-collector ring, the 27-generator shaft, the 28-rotor disk, 29-coupling, 30-rotor jib.The reciprocal pivot angle of α-rocking arm and generator amature.
The swing type generator is positioned at a side of opposed pistons oscillating engine, and feature is that each rocking arm 1 links with generator shaft 27 by its pitman arm shaft 16, coupling 29.When rocking arm promotes bent axle by connecting rod, directly drive generator by pitman arm shaft, coupling again and do same oscillating motion, change the kinetic energy of swinging into electric energy.
Swing type generator another feature is among the present invention: rotor 19 is the thin walled cylinder shape, between inner stator 18 external stators 20.The two arranged concentric, two ends of rotor have collector ring 16 to be contained on the rotating sleeve 23 of generator shaft 27 tape insulations.Wherein near the collector ring of rocking arm one side directly and rotor disk 28 rotors 19 be integral.The opposite side collector ring then connects the rotor jib 30 of rotor.Inner stator is interted therebetween fixedly inner stator by 22, is around with corresponding stator yoke field winding 21 in the groove of inside and outside stator.
Fig. 4 is the generator circuit principle.When voltage is U
BThe dc magnetizing electric current I
BDuring by yoke field winding 21, produce the magnetic flux distribution in magnetic field between inside and outside stator shown in the dotted line among Fig. 3 (similar conventional DC single-stage motor magnetic flux distribution), when rotor reciprocally swinging cutting magnetic field magnetic flux, induction produces alternating current by 25 outputs of two ends collector ring 26 brushes.The frequency of alternating current equals the reciprocally swinging frequency of rocking arm and rotor.Near sinusoidal waveform.The size of output voltage U electric current I then depends on the size of reciprocating frequence and amplitude alpha.
