이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 내지 도7에 도시된 바와 같이 마이컴(72)에 미리 기억되어 있는 청소주기가 되면, 마이컴(72)의 출력포트를 통해 모터구동부(74)로 반전신호가 출력되며, 모터구동부(74)의 출력단에 접속되어 있는 감속모터(60)의 모터축(62)과 피니언(64)이 회전된다.As shown in FIGS. 1 to 7, when the cleaning cycle is stored in advance in the microcomputer 72, an inverted signal is output to the motor driving unit 74 through the output port of the microcomputer 72, and the motor driving unit ( The motor shaft 62 and the pinion 64 of the reduction motor 60 connected to the output terminal of 74 are rotated.

이때 회전링(40)의 내주면에 형성되어 있는 내접기어(44)가 피니언(64)과 치합되어 있으므로, 감속모터(60)로부터 발생된 회전력은 피니언(64)을 통해 내접기어(44)로 전달되면서 회전링(40)이 브이롤러(34)의 안내를 받으면서 회전되며, 고무댐퍼(50)에 의해 회전링(40)과 결합되어 있는 램프커버(52)도 동시에 회전된다.At this time, since the internal gear 44 formed on the inner circumferential surface of the rotary ring 40 is engaged with the pinion 64, the rotational force generated from the reduction motor 60 is transmitted to the internal gear 44 through the pinion 64. The rotary ring 40 is rotated while being guided by the v-roller 34, and the lamp cover 52 coupled to the rotary ring 40 by the rubber damper 50 is also rotated at the same time.

위와 같이 회전링(40)이 회전하는 동안 광센서(82)에 구비되어 있는 발광소자(D1)로부터 방사되는 빛이 회전링(40)의 단면에 형성되어 있는 각도패턴(80)에서 반사되면서 광센서(82)의 수광소자(PT)에 입사되어 회전링(40)의 회전각도가 검출되어 마이컴(72)의 입력포트를 통해 입력되며, 이때 마이컴(72)은 회전링(40)이 180° 회전된 위치로 판정되면, 모터정지신호를 모터구동부(74)로 출력하여 감속모터(60)를 즉시 정지시키게 된다.While the rotary ring 40 rotates as described above, the light emitted from the light emitting device D1 provided in the optical sensor 82 is reflected by the angle pattern 80 formed on the end surface of the rotary ring 40. The rotation angle of the rotation ring 40 is detected by entering the light receiving element PT of the sensor 82 and is input through the input port of the microcomputer 72. In this case, the rotation ring 40 of the microcomputer 72 is 180 °. If it is determined that the rotated position, the motor stop signal is output to the motor driving unit 74 to immediately stop the reduction motor 60.

이때 램프커버(52)가 180° 반전되었기 때문에 상하가 반전되어 상측에 쌓여 있던 먼지와 이물질이 자중에 의해 밑으로 일부 떨어지게 된다.At this time, since the lamp cover 52 is inverted by 180 °, the upper and lower sides are reversed, and dust and foreign matter accumulated on the upper side are partially dropped by self weight.

이후 마이컴(72)은 또 다른 출력포트에 접속되어 있는 초음파구동부(76)를 구동하여 초음파구동부(76)의 출력단에 접속되어 있는 압전진동자(70)를 구동하게 되며, 압전진동자(70)로부터 발생된 초음파진동은 램프커버(52)에 직접 전달되어 램프커버(52)의 표면에 쌓인 먼지나 타이어분진을 제거하게 된다.Thereafter, the microcomputer 72 drives the ultrasonic drive unit 76 connected to another output port to drive the piezoelectric vibrator 70 connected to the output terminal of the ultrasonic drive unit 76 and is generated from the piezoelectric vibrator 70. The ultrasonic vibration is transmitted directly to the lamp cover 52 to remove the dust or tire dust accumulated on the surface of the lamp cover 52.

이때 램프커버(52)는 고무댐퍼(50)를 통해 회전링(40)에 결합되어 있기 때문에 램프커버(52)로 전달된 진동은 고무댐퍼(50)에 의해 대부분 차단되어 회전링(40)이 진동에 의해 손상되는 것이 방지된다.At this time, since the lamp cover 52 is coupled to the rotary ring 40 through the rubber damper 50, most of the vibration transmitted to the lamp cover 52 is blocked by the rubber damper 50 so that the rotary ring 40 is closed. It is prevented from being damaged by vibration.

이후 마이컴(72)은 일정시간 동안 압전진동자(70)를 구동한 다음 시간이 경과되면, 구동을 중단한 다음 청소주기가 될 때까지 정지된 상태를 유지하게 된다.Thereafter, the microcomputer 72 drives the piezoelectric vibrator 70 for a predetermined time, and when the time elapses, the microcomputer 72 stops the driving and maintains the stopped state until the cleaning cycle is reached.

이상에서 설명한 바와 같은 본 발명은 램프커버를 반전시킬 수 있는 반전장치와 초음파진동자에 의해 교통신호등의 램프커버를 주기적으로 청소해 주도록 구성되어 있기 때문에 램프커버를 항상 깨끗한 상태로 유지할 수 있어 신호등의 밝기를 지속적으로 유지할 수 있는 효과가 있으며, 특히 초음파진동 전에 램프커버가 반전되어 상하가 뒤바뀌도록 구성되어 있기 때문에 램프커버에 쌓인 먼지나 타이어분진의 청소가 효율적으로 되는 효과가 있다.As described above, the present invention is configured to periodically clean the lamp cover such as a traffic signal by an inverter capable of inverting the lamp cover and an ultrasonic vibrator, so that the lamp cover can be always kept in a clean state, and thus the brightness of the signal lamp can be maintained. It is effective to maintain the continuous, especially since the lamp cover is inverted before the ultrasonic vibration is configured to reverse the upper and lower dust and tire dust accumulated on the lamp cover is effective to be effective.

더 나아가서 본 발명은 마이컴(마이크로 콘트롤러)에 의해 미리 설정된 주기에 따라 자동으로 청소하도록 구성되어 있기 때문에 신호등의 청소비용을 크게 절감할 수 있는 효과도 기대할 수 있다.Furthermore, since the present invention is configured to automatically clean according to a preset cycle by a microcomputer (microcontroller), the effect of greatly reducing the cleaning cost of a traffic light can be expected.
