Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 12, when the cleaning cycle preset by the timer built in the microcontroller 130 is reached, the microcontroller 130 moves the stepping motor 102 through the motor driving unit 136. Drive to reverse the serration shafts 82, 83, 84 and the cleaning pads 92, 93, 94 so that the lamp units 50a, 50b, 50c can be rotated horizontally. do.

That is, when the pinion 104 installed on the motor shaft of the stepping motor 102 is rotated in the counterclockwise direction (CCW), the rack 105 engaged with the pinion 104 is retracted and the slip coupler 106 is rotated. Is linearly moved to the rear side, and the serration shafts 82, 83, 84, which are connected to the slip coupler 106, are reversed, and the cleaning pads 92, 93, 94 are reversed at the same time.

At this time, the serration shafts 82, 83, 84 are linearly guided by the serration holes 72a formed in the electric pulleys 72, 73, 74, and the electric pulleys 72, 73 ( 74 is maintained by the bracket (70) 71 does not move in place and stopped, the rack 105 is prevented from sagging by the guide roller 107 located on the lower side.

Afterwards, the microcontroller 130 drives the inverting motor 66 through the driving unit 132 to form the vertical hollow shaft 60 through the worm 67, the worm wheel 68, the electric gear 69b, and the driven gear 69a. The vertical hollow shaft 60 is rotated horizontally by transmitting power, and the lamp units 50a, 50b, 50c installed on the vertical hollow shaft 60 are horizontally rotated together with the vertical hollow shaft 60. When it is rotated 180 degrees, the lamp cover 56 positioned in the floodlight holes 42, 44 and 46 formed in the signal lamp body 40 is positioned inside and the lamp cover 56 positioned inside. 58 is exposed to the outside through the light transmission holes 42, 44, 46.

At this time, since the vertical hollow shaft 60 is supported by the traffic light main body 40 by the shaft support plates 62 and 64 at the upper and lower ends, only the horizontal rotational movement is possible on the spot, and the lamp units 50a and 50b ( The power and the signal supplied to 50c) are made possible by the wire 400 installed to pass through the center of the vertical hollow shaft 60.

In addition, when the vertical hollow shaft 60 is rotated, the rotary encoder 34 installed at the upper end of the vertical hollow shaft 60 detects the rotation angle of the vertical hollow shaft 60 to the input port of the microcontroller 130. When the microcontroller 130 determines that the vertical hollow shaft 60 is rotated 180 °, the microcontroller 130 stops the inversion motor 66 to rotate the lamp units 50a, 50b and 50c by 180 °. Will be maintained.

In addition, the vertical hollow shaft 60 and the lamp units 50a, 50b and 50c are prevented from reversing by the worm 67 and the worm wheel 68 installed in the inverting motor 66 so that the inverting motor 66 is stopped.

At this time, the cleaning pads 92, 93 and 94 are brought into close contact with the lamp covers 56 and 58 located inside the traffic light main body 40.

In addition, after the cleaning pads 92, 93, 94 are in close contact with each other, the microcontroller 130 stops the driving of the stepping motor 102 and then drives the piezoelectric vibrator 30 through the ultrasonic driver 32 to clean the cleaning pad 92. The lamp cover 56, 58 by rotating the cleaning pads 92, 93, 94 by driving the cleaning motor 110 through the motor driving unit 134 while giving vibration to the (93) (94). Remove dust 31 attached to the.

At this time, the dust 31 dropped from the lamp covers 56 and 58 is collected by falling into the dust collectors 150, 152 and 154 installed inside the signal lamp body 40 and the lamp covers 56 and 58. ) Is cleaned by the brush 92b implanted into the cleaning pads 92, 93, and 94.

That is, when the cleaning motor 110 is rotated, from the driving pulley 114 installed on the motor shaft 112 of the cleaning motor 110 to the electric pulley 72 located on the uppermost side through the driving belt 116. Power is transmitted, and the remaining electric pulleys 72, 73 and 74 are connected to each other by the electric belt 118, so that the power transmitted to the upper electric pulley 72 is transferred by the electric belt 118. All the electric pulleys 72, 73 and 74 are rotated at the same time as they are transmitted to the electric pulleys 73 and 74, and lamp covers 56 and 58 respectively installed in the lamp units 50a, 50b and 50c. ) Polished.

Thereafter, the microcontroller 130 continues the driving of the cleaning motor 110 for a predetermined time and then stops the driving.

On the other hand, in the case of removing the dust 31 accumulated in the dust collectors 150, 152 and 154 installed inside the traffic light body 40, the doors 160 and 162 installed on the rear of the traffic light body 40. When the dust (31) accumulated in the dust collector (150, 152, 154) using a cleaning tool such as a vacuum cleaner in the state that the) (164) is opened, the dust collector (150) (152) (154) The dust 31 accumulated in the can be easily removed, and the doors 160, 162 and 164 are closed again after cleaning.

As described above, the lamp units 50a, 50b, and 50c installed in the signal lamp body 40 are periodically inverted according to a cleaning cycle set in advance, and cleaning pads 92 and 93 installed inside the signal lamp body 40 are provided. 94, and cleaning pad 92 (before rotating the lamp units 50a, 50b, 50c to prevent interference during rotation of the lamp units 50a, 50b, 50c). 93, 94 are reversed by the stepping motor 102, and then, when the lamp units 50a, 50b, 50c are reversed, they are advanced again and returned.

As described above, the present invention is configured to automatically clean the lamp cover by repeating automatically every predetermined cleaning cycle, so that the brightness of the signal lamp can be always maintained in an optimal state, and the light transmission power of the lamp cover is improved. It has the effect of saving power, and two lamp covers are installed on the front and back of the lamp unit, and the lamp unit is configured to reverse 180 ° in the horizontal direction when cleaning the lamp cover. It is possible to use continuously without stopping the traffic light, and since the cleaning pad is configured to retreat by the stepping motor when the lamp unit rotates, there is an effect of avoiding interference between the lamp unit and the cleaning pad.

Furthermore, in the present invention, since the vertical hollow shaft connected to the lamp unit is formed in a hollow shape, it is possible to insert an electric wire for supplying power to the lamp unit or an electric wire for communication, so that the wiring is simple and prevents twisting of the electric wire. In addition, the lamp unit rotates by external force due to the reverse action of the worm and the worm wheel because it is designed to transmit the power generated from the reversing motor for the rotation of the vertical hollow shaft to the vertical hollow shaft through the worm and the worm wheel. It has the effect of preventing a plurality of electric pulleys, and since the electric pulley is structured to be interlocked by an electric belt, it is possible to drive a plurality of cleaning pads using one cleaning motor, thereby simplifying the configuration. It is effective and removes dust falling from the cleaning pad by the dust collector installed inside the signal lamp body. Because it is designed to be collected and collected, the inside of the traffic light main body can be kept more clean, and the dust collector is configured to periodically remove dust accumulated in the dust collector through the openings and doors installed at the rear of the traffic light main body. There is an effect that the collection of dust collected in a more convenient, and the dust removal operation is made more quickly because it is configured to impart ultrasonic vibration to the cleaning pad by the piezoelectric vibrator when rotating the cleaning pad.
