Description

A kind of street lamp from moving lamp

Technical field

Traffic lighting technical field under the utility model, particularly a kind of street lamp from moving lamp.

Technical background

Known, traffic is now extended in all direction, and various street lamps emerge in an endless stream, and feature is different, gives people's night traffic, and life is provided convenience, and becomes the indispensable part of modern city.But all street lamps have a shortcoming, change exactly lamp trouble, and lamp is spoilt and has randomness, each maintenance also needs huge expense.General light pole is all more than 5 meters, when the lamp maintain and replace that is spoilt very inconvenient, some street light lamp bulb life-span is about 4000 hours at present, almost every about half a year, just need to change once, need to spend huge manpower and materials like this, and some street lamp, near high voltage transmission line, has certain potential safety hazard if Multiple through then out instrument climbs up to change.Therefore how to allow street lamp change and become easier, even reducing common replacing number of times is a very considerable problem.

Summary of the invention

Problem for above-mentioned middle existence, the utility model proposes the method for solution, its technical scheme is: design a kind of street lamp, with reference to electric fan operation principle, a stepping motor is installed on top at light pole, a columniform syndeton (the inside is Control center, can synchronously rotate with stepping motor rotating shaft) is installed on stepping motor axle head, the bulb of some is installed above.Lampshade of outer mask, is used for waterproof, and solar panel is installed in lampshade top, by solar electrical energy generation, electrical power storage is got up and is powered to single chip machine controlling circuit, stepper motor.When wherein alight bubble breaks down, just can press gauge tap, by Single-chip Controlling stepper motor, rotate certain angle the bulb breaking down is changed, Single-chip Controlling relay makes corresponding bulb live wire switch closed simultaneously, this bulb circuit is connected luminous.Realize the object automatically more changing the bulb.When all bulbs, all use after breaking down and just lampshade can be taken off, all bulbs are changed once.

The beneficial effects of the utility model are: realized the automatic replacing of bulb, having solved people needs a repeatedly difficult problem for repairing by climbing bulb.If 6 bulbs are for example installed in the above, adopt the good lampshade of humidity resistance just can guarantee about 3 years the replacing of can not employment getting on, when a common cleaner cleans, press the replacing that switch can be realized trouble light, maintenance cost reduces greatly.Therefore this novel street lamp is changed street lamp and just can be replaced the original lamp that changes many times, and use for a long time, has been saved a large amount of manpower and materials.And on the street lamp of road, solar panel is installed, by solar electrical energy generation, can be given the power supply of street lamp stepper motor on the one hand, can also provide part electric power to traffic lighting, realized the extensive utilization of regenerative resource, be conducive to social sustainable development.

The specific embodiment

The selection of motor: exemplify in this programme 6 bulbs (other quantity bulbs also can similar designs) are installed in lampshade, lamp is once changed in 60 ° of realizations of stepper motor rotation.It is 35BY38S03 permanent magnetism stepper motor that this programme adopts model, often gives pulse of stepper motor, and stepper motor rotates 7.5 °.While changing lamp, by a switch, 60 ° of stepper motor rotations, have realized and have once changed lamp at every turn.Select TA8435H as the driver of stepper motor, as shown in figure 11,2,3,4 pin of J1 do not connect P1.1,1.2, the p1.3 mouth of single-chip microcomputer, 1 pin of J1, ground and the VCC of 5 pin single-chip microcomputers.VCC selects 5V power supply.1,2,3,4 of J2 joins with A, A, B, the B of stepper motor respectively, and 5 pin of J2 and the GND of stepper motor join.Single-chip microcomputer P1.1 mouth control step motor rotary speed and pulse number, P1.2 mouth control step motor positive and inverse, P1.3 mouth enables control end.This programme 1/8 segmentation working method, single-chip microcomputer P1.1 pin each second is to pulse of stepper motor, 0.9375 ° of stepper motor rotation, often, by once changing lamp switch, single-chip microcomputer produces 64 pulses, 60 ° of stepper motor rotations, realize and once change lamp, approximately 64 seconds time.

The selection of control program: 6 relays by single-chip microcomputer P1.0 to six IO mouth centralized Control of P1.5, selected successively according to the order of changing lamp, as shown in Figure 7, single-chip microcomputer P1.0 mouth control relay, connect the live wire that this bulb is corresponding, bulb is luminous, and relay adds fly-wheel diode, the reciprocal inductance that while preventing triode cut-off, relay coil forms; As shown in flow chart 6, often by a switch (6), stepper motor rotation 60 is spent, relay corresponding to single-chip microcomputer P1 mouth gating makes this bulb luminous simultaneously, after changing lamp 5 times, single-chip microcomputer enters wait state, presses and changes button stepper motor not in rotation, now just need to take off lampshade and again change 6 bulbs, press hand-reset button and make monolithic processor resetting, from newly starting working.

Structure mounting portion: stepper motor (9) is installed on lamp stand (2) top, stepper motor rotates required electric energy and is provided by solar panel (8) or external power supply on outer lampshade (1), outer lampshade (1) has the function of waterproof and generating, lampshade orlop is partly transparent part, convenient illumination, whole lampshade is hermetically-sealed construction.Stepper motor (9) sends pulse signal control step electric machine rotation by switch (6) control single chip computer, in stepping motor rotating shaft end, there are one and motor coaxle slewing circle tubular coupling part (4), on cylinder, leave some bulbs and groove is installed for bulb mounting; It is upper that the live wire on bulb grooves as all in Fig. 8 top is all connected to firewire electrode (15) in control integration part (4) inside by relay controller switch (10), and bulb groove zero line is directly connected on zero wire electrode (11); The zero live wire of power supply (not drawing in Fig. 9 structure) is connected on static fixing brush (13), brush and with cylindrical electrode (12) close contact of machine shaft synchronous rotary, electrode (12) is with contacting well with static brush all the time in the process of electric machine rotation, and frictional force is less, electric conductivity good (the brush-commutated structure in similar direct current generator), cylinder electrode (12) is drawn zero live wire (14) and is connected on respectively on electrode (11), (15), so far just completed the connection circuit figure of bulb, and wire can not be wound around when rotated, can guarantee the conducting of line related.

During normal operation, single-chip microcomputer choose corresponding relay make under bulb live wire connect, this bulb can be normally luminous.When bulb breaks down (as filament blow), just need to more change the bulb.Source for street light maintenance person is by a control button (6), single-chip microcomputer response button signal, producing 60 ° of pulse signal control step motor rotations stops, with contiguous bulb, replace the bulb breaking down, while single-chip microcomputer is chosen corresponding relay, and (single-chip microcomputer look-up table is easy to realize the selection of corresponding relay, here just repeat no more), new bulb is connected just can be luminous, changes lamp process and finish.Because stepper motor can be stablized a certain fixed angle of accurate rotation, performance is very stable, and when street lamp is normally worked, single-chip microcomputer chooses a certain relay to continue conducting, bulb continues luminous, when this bulb is changed, and the corresponding relay of Single-chip Controlling, this bulb and live wire are disconnected, so far just completed the automatic Renewal process of bulb.Whole process only needs operation-control switch (6), changes lamp process very easy.
