Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Embodiment 1, consults Fig. 4 and Figure 10, and the present invention mainly comprises suction force pendulous device 1, torsion spring elastic potential energy TRT 2, time-setting mechanism 3 and street lamp illuminating part 4.
The critical piece suction plate 11 of suction force pendulous device 1 is located at the position (referring to Fig. 1 to Fig. 4) near train and railway, every row train is through the suction force of out-of-date generation, suction plate 11 is swung towards train directions, its power is that torsion spring elastic potential energy TRT 2 accumulates elastic potential energy, and by the regulation and control of time-setting mechanism 3, make torsion spring slowly discharge elastic potential energy, drive dc generator generating.
Referring to Fig. 3, Fig. 4 and Fig. 5, suction force pendulous device 1 comprises the suction plate 11 and the support 12 that are located at street lamp column 41 front portions, two chains on street lamp column top 13, two sprocket wheels 14, counterweight block 15, transverse axis 16, the first bevel gear 17, the second bevel gear 18, the longitudinal axis 19 and longitudinal axis support plates 191; Support 12 one end and suction plate 11 are connected, the other end and street lamp column 41 lower hinge. When train is through out-of-date, suction plate 11 obtains suction force, and these two parts that are fixed together can swing towards train directions around described hinged place. The amplitude swinging, is controlled by the upper limit bar 91 and the lower limit bar 92 that are located on street lamp column. The size of suction force is directly proportional to the area of suction plate 11, that is to say, suction plate 11 is larger, and the suction force of acquisition is also larger. After train passes through, suction force disappears, and the weight of counterweight block 15, by chain 13, returns to initial position by suction plate 11, in order to swing next time. Transverse axis 16 is through street lamp column 41 tops, and the both ends that transverse axis 16 stretches out in outside street lamp column 41 are provided with respectively a sprocket wheel 14. On each sprocket wheel 14, all engage a chain 13, one end of every chain 13 is connected in suction plate 11 tops, and the other end is connected in counterweight block 15; In sprocket wheel 14, be provided with ratchet, this sprocket wheel is similar to the sprocket wheel that contains ratchet in bicycle rear. Referring to Fig. 3, in the time that chain 13 is with movable sprocket 14 counterclockwise to rotate, transverse axis 16 rotates together; In the time that sprocket wheel 14 rotates clockwise, due to the anti-reverse function of ratchet, transverse axis 16 does not rotate with sprocket wheel 14. Thereby ensure that 23 of torsion springs are tightened, can not be back-outed. If but torsion spring 23 tightened excessively, the elastic force that likely there will be torsion spring 23 upper ends 232 to discharge rotates backward the second bevel gear 18, causes transverse axis 16 to clockwise rotate, thereby does not reach the result that tightens torsion spring 23. So, be provided with non-return ratchet mechanism 5(referring to Fig. 3, Fig. 5, Figure 12 and Figure 16). This non-return ratchet mechanism 5 is by the ratchet 51 being located on transverse axis 16, and the ratchet 52, detent pin 53 and the ratchet torsion spring 54 that are located on street lamp column 41 form; Ratchet torsion spring 54 forces ratchet 52 to engage with ratchet 51 all the time, clockwise rotates thereby can prevent transverse axis 16. Be positioned on the transverse axis 16 of street lamp column 41 the first bevel gear 17 is set, be positioned at and on the longitudinal axis 19 of street lamp column 41, the second bevel gear 18, the first bevel gears 17 be set and engage with the second bevel gear 18, the longitudinal axis 19 is articulated with street lamp column 41 by longitudinal axis support plate 191; In the time that transverse axis 16 rotates, the first bevel gear 17 being connected on transverse axis 16 drives the second bevel gear 18, the longitudinal axis 19 to rotate together, then the longitudinal axis 19 tightens power for the torsion spring in elastic potential energy TRT 2 provides, and also tightens power for the clockwork spring in time-setting mechanism 3 provides simultaneously. The number of turns that torsion spring is tightened is more, and the elastic force of release is also larger. The quantity of the number of turns that torsion spring is tightened, can recently determine with the number of teeth of the first bevel gear 17 and the second bevel gear 18. In addition, can also between sprocket wheel 14 and the first bevel gear 17, speed changer be set, to improve the rotating speed of the first bevel gear 17, this is also a kind of method that torsion spring is tightened the number of turns and increases.
Referring to Fig. 4, Fig. 5, Fig. 7, Figure 11, Figure 13 and Figure 14, torsion spring elastic potential energy TRT 2, be located in street lamp column 41, it comprises the first overload-release clutch 21, upper torsion spring set 22, torsion spring 23, lower torsion spring set 24, gear wheel 25, pinion 26, gripper shoe 20, speed changer 27, speed regulator 28, dc generator 29 and prevention dish 291 thereof; The longitudinal axis 19 in suction force pendulous device 1 connects the first overload-release clutch 21, the first overload-release clutches 21, upper torsion spring set 22, torsion spring 23, lower torsion spring set 24, gear wheel 25 and is linked in sequence; Gear wheel 25 is connected to the bottom of lower torsion spring set 24, and lower torsion spring set 24 is hinged by lower supporting plate 241 and street lamp column 41, and its bottom is connected with the bearing 43 that is positioned at street lamp column 41 bottoms; Speed changer 27 is fixed on street lamp column 41 inside by gripper shoe 20, and its output is connected with speed regulator 28, and speed regulator 28 is connected with dc generator 29, and the output of dc generator 29 arranges arresting disc 291; The input of speed changer 27 arranges pinion 26, and pinion 26 engages with gear wheel 25; When in the jammed situation of arresting disc 291, dc generator 29, speed regulator 28, speed changer 27, pinion 26, gear wheel 25, lower torsion spring set 24 are all stopped. Because the bottom 231 of torsion spring 23 and lower torsion spring set 24 link together, therefore the bottom of torsion spring 23 is also transfixion. And upper torsion spring set 22 rotates together with the longitudinal axis 19 with the first overload-release clutch 21, because the upper end 232 of torsion spring 23 links together with upper torsion spring set 22, thus the also rotation thereupon of the upper end 232 of torsion spring 23, like this, torsion spring 23 is constantly tightened, accumulation elastic potential energy. But turned round to obtain tension when torsion spring 23, may be caused the damage of related components, so adopted the overload protection function (referring to Figure 14) of overload-release clutch. When namely the first overload-release clutch 21 has exceeded its braking moment, the rotation of skidding of the first overload-release clutch 21, thus no longer tighten torsion spring 23. This overload-release clutch can adopt known overload-release clutch, for example, and castellated overload-release clutch as shown in figure 14. After arresting disc 291 is released, the elastic potential energy that torsion spring 23 starts slowly to discharge accumulation, the bottom 231 of torsion spring 23 starts to rotate, and drives gear wheel 25, pinion 26, speed changer 27, speed regulator 28 and dc generator 29 to rotate generating. The effect of speed changer 27 is that the rotating speed that pinion 24 is obtained further brings up to the rated speed that dc generator 29 generates electricity. This speed changer can adopt known speed changer. The effect of speed regulator 28 is to stablize the rotating speed that speed changer 27 is exported, because the elastic potential energy that torsion spring discharges is weak after normally first strong, can cause speed changer 27 to export rotating speed first quick and back slow, is unfavorable for the normal work of dc generator. This speed regulator can adopt known mechanical centrifugal formula speed regulator. The blocking and unclamp by time-setting mechanism 3 of described arresting disc 291. This torsion spring elastic potential energy TRT provides electric power for street lamp illuminating part 4.
Referring to Fig. 8 to Figure 13, time-setting mechanism 3, is located in street lamp column 41, and it mainly forms (referring to Fig. 8, Fig. 9) by clockwork 7 and control lever mechanism 8. Control lever mechanism 8 is mainly used for blocking the rotation of the arresting disc 291 on dc generator, and clockwork 7 is responsible for determining when control lever mechanism 8 blocks arresting disc 291. Control lever mechanism 8 mainly comprises control lever support 81, elasticity control lever 82, two stand spring 83; Control lever support 81 is fixed on street lamp column 41 inside. Elasticity control lever 82 is located in the square hole 811 of control lever support, can in square hole 811, slide; Two stand spring 83 are located at respectively in the spring eye 812 of control lever support, its one end withstands in spring eye, the other end withstands on elasticity control lever 82, its effect is to force elasticity control lever afterbody 821 to contact with cam 74, arresting disc 291 discontinuous connections on elasticity control lever head 822 and described dc generator; Namely, when the chimb of cam 74 withstands elasticity control lever afterbody 821, by control lever spring 823, force elasticity control lever head 822 to snap in arresting disc 291, arresting disc 291 is by stall, and dc generator 29 just stops generating; Otherwise the concave edge of cam 74 contacts with elasticity control lever afterbody 821, elasticity control lever head 822 just leaves arresting disc 291, and dc generator 29 just starts generating. The elastic force of control lever spring 823 should be greater than two stand spring 83 sums, and should effectively block arresting disc 291. The effect of control lever spring 823 is the wear extenies that compensate at any time elasticity control lever head 822 and arresting disc 291, and extended its service life. (referring to Figure 11 to Figure 13) clockwork 7 mainly comprises that it is clock 73 and the cam 74 of 24 hours that first gear 79, the second plate gears 78, time rotating shaft 77, the second overload-release clutch 71, clock support 72, hour hand axle turn around; First gear is arranged on the longitudinal axis 19 of suction force pendulous device, and it engages with the second plate gear 78 being arranged in time rotating shaft 77; Time rotating shaft 77 is articulated with street lamp column 41 inside by rotating shaft support plate 771, and is connected with the second overload-release clutch 71, and the second overload-release clutch 71 tightens axle (not shown) with the clockwork spring of clock 73 and is connected; Clock 73 is fixed on described street lamp column 41 inside by clock support 72, the wherein said described cam 74 of hour hand axle 75 coaxial connection; Clock 73 can adopt known hour hand axle to turn around to be the timing topology of 24 hours. Like this, to turn around be also 24 hours to cam 74. The arc length of the chimb of cam 74 is the time that daytime, street lamp extinguished, and the arc length of the concave edge of cam 74 is the time that night, street lamp was lighted. The effect of the second overload-release clutch 71, prevents that clock clockwork spring and associated mechanisms from being transshipped damage and arranging, and its internal structure is also identical with the first overload-release clutch, also can adopt known overload-release clutch. This time-setting mechanism timing controlled starts torsion spring elastic potential energy TRT 2 and starts generating.
Street lamp illuminating part 4, it is contained in street lamp column 41 tops, and is electrically connected with dc generator 29, the electric energy luminous lighting that this street lamp illuminating part 4 was produced by described torsion spring elastic potential energy TRT 2 at night;
In sum, use the method for said apparatus to be: on daytime, the chimb of the cam 74 always rotating pushes up elasticity control lever 8 to arresting disc 291 all the time, and arresting disc 291 is stuck, and dc generator 29 can not rotate generating, and street lamp illuminating part 4 is not luminous; In the time of train process street lamp, the air-flow between train and suction plate 11 is accelerated, and pressure reduces, thereby suction plate 11 is produced to suction force, and suction plate 11, support 12 are swung to train; Suction plate 11 tops pull chain 13, and rotate the upper end 232 with this with movable sprocket 14, the first bevel gear 17, the second bevel gear 18, the longitudinal axis 19, the first safety clutch 21, upper torsion spring set 22 and torsion spring, store the elastic potential energy of torsion spring; Meanwhile, the first gear 79 being located on the longitudinal axis 19 drives the second plate gear 78, time rotating shaft 77, the second overload-release clutch 71, twists the clockwork spring of clock 73 by the second overload-release clutch 71, gives the hour hand axle 75 of clock 73 and the rotation of cam 74 with power;
After train passes through, suction force disappears, and the gravity of counterweight block 15 pulls chain 13, makes suction plate 11 be returned to original state; Repeatedly train passes through, and sprocket wheel is rotated for more than 14 time, and torsion spring 23 is accumulation elastic potential energy constantly, and meanwhile, the clockwork spring of clock 73 is also constantly tightened; When tightening the moment of torsion of torsion spring 23 and exceed the braking moment of the first overload-release clutch 21, the first overload-release clutch 21 skids, thereby avoids torsion spring elastic potential energy TRT 2 to transship and damage; On the other hand, when tightening the moment of torsion of clockwork spring and exceed the braking moment of the second overload-release clutch 71, the second overload-release clutch 71 skids, thereby avoids clockwork overload and damage;
To night, elasticity control lever afterbody 821 drops on the concave edge of the cam 74 in rotation, arresting disc 291 on dc generator 29 is released, dc generator 29 rotates, and torsion spring 23 slowly discharges elastic potential energy, and the elastic force of torsion spring 23 is by the engaged transmission of gear wheel 25 and pinion 24, improve rotating speed through speed changer 27, through speed regulator 28 automatic stabilisation rotating speeds, drive dc generator 29 to rotate generating, for street lamp illuminating part 4 luminous lightings.
To daytime, the chimb of the cam 74 that elasticity control lever 82 is being rotated again pushes up to arresting disc 291, and arresting disc 291 is stuck, and dc generator 29 stops operating, no longer generating, and street lamp illuminating part 4 extinguishes;
So go round and begin again, the suction force that street lamp illuminating part 4 relies on train to produce, at noctilucence, extinguishes by day.
