본 발명은 표지판 및 금속판에 먼지나 이물질을 제거하는 방법에 관한 것이다. 더욱 상세하게는, 표지판이나 금속판에 먼지나 이물질등을 초음파 진동자로 제거함으로써 건물 및 표지판의 청결을 유지하고, 도로 표지판 청소시 차량 정체 및 차량 사고를 미연에 방지하도록 도와주는 기술이다. The present invention relates to a method for removing dust and foreign matter on the sign and the metal plate. More specifically, it is a technology that helps to maintain the cleanliness of buildings and signs by removing dust or foreign matter on the signs or metal plates with ultrasonic vibrators, and to prevent traffic jams and vehicle accidents.

일반적으로 건물에 부착되어 있는 금속판이나 유리등은 일정한 주기로 사람이 건물 옥상에서 줄을 타고 내려오며 청소를 하는 경우가 많다. 하지만 이는 간혹 청소하는 사람의 컨디션이나 안전 부주의에 의하여 생명의 위협을 받는 경우도 간혹 있으며, 용역을 주고 사용하는 경우에도 상당량의 비용과 청소시 사용하는 물이 건물 주위를 지나가는 사람들에게 튀는 경우 민원이 들어오는 경우도 있다. In general, metal plates or glass, etc. attached to a building are often cleaned by people descending from the roof of the building at regular intervals. However, this is sometimes a life-threatening condition due to the condition of the cleaner or the carelessness of the cleaner, and even if the service is used for a considerable amount of money and the water used for cleaning splashes on people passing around the building, It may come in.

또한 표지판의 경우 청소해야 하는 표지판의 수는 많지 않지만 도로의 특성상 사고의 위험을 가지고 있으며, 청소시 다른 차량의 교통을 방해 교통체증의 원인을 제공하기도 한다. 또한 근래에는 청소용 차량등 고가의 장비를 사용하여 청소를 함으로써 고가 장비의 비용 및 유지 등에 상당히 많은 비용이 지출되고 있는 것으로 알고 있다. In the case of signs, the number of signs that need to be cleaned is not high, but there is a risk of an accident due to the nature of the road, and when cleaning, it may cause traffic jams that obstruct other traffic. In recent years, cleaning by using expensive equipment such as a cleaning vehicle is known that a lot of money is being spent on the cost and maintenance of expensive equipment.

이외에 최근에는 표지판이나 금속표면에 먼지나 이물질이 부착되지 않도록 특수 코팅 방법을 사용하고는 있으나 코팅 비용이 많이 들고 환경적인 제약(코팅 사이즈, 사용온도등)이 많아 아직 실용화가 되지 않고 있다. In addition, recently, special coating methods are used to prevent dust or foreign matter from adhering to signs or metal surfaces. However, the coating is expensive and environmental constraints (coating size, operating temperature, etc.) have not been put to practical use.

본 발명은 이러한 점들을 감안하여 안출된 것으로, 표지판의 경우 먼지 및 이물질에 의한 표지판의 기능저하, 표지판 청소를 위한 교통정체 및 교통사고의 위험율 증대등을 미연에 방지 할 수 있으며, 건물 외벽에 붙어있는 금속판등에 설치하여 건물의 청결 및 청소자의 안전율을 높여주는 것이다. The present invention has been made in view of these points, in the case of the sign can prevent the deterioration of the sign due to dust and foreign matter, traffic congestion for the sign cleaning and increase the risk of traffic accidents in advance, It is installed on a metal plate, etc., to increase the cleanliness of the building and the safety rate of the cleaner.

이하, 본 발명의 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 과 도 2 는 본 발명 표지판 자동 세척장치의 제1실시예를 보인 것으로서, 표지판 위에 방향 지시를 알리기 위해 도장한 면을 가지고 있으며, 이 도장면은 절연성(10)을 가지고 있으며, 표지판 상하부에 끝을 피복 벗긴 전선을 절연면에 통전스위치(51) 부착시킨다. 이후 진동 완충제인 고무판(70)을 연결하고, 평소에는 초음파 진동자(60)를 작동 시킬 수 있는 통전 스위치(51)가 통전이 되지 않아, 작동하지 않다가 비나 기타 도장면에 물기가 촉촉이 묻어 통전이 되어 통전스위치(51)가 작동되면, 표지판(10) 뒤쪽에 일정한 간격으로 부착되어 있는 초음파 진동자(60)로 초음파 발진기(50)에서 신호를 보내주어 표지판(10) 표면에 초음파를 형성시킨다. 이에 의해 표지판(10) 표면에 묻은 먼지나 이물질이 물과 함께 바닦으로 흘러 떨어지도록 한다. 1 and 2 show a first embodiment of the automatic sign cleaning device of the present invention, and has a surface painted to indicate a direction indication on the sign, this painted surface has an insulating (10), the upper and lower signs Attach the bare wire to the insulation switch 51 on the insulating surface. Then, the rubber buffer 70 is connected to the vibration buffer, and the energization switch 51 capable of operating the ultrasonic vibrator 60 is not energized normally. When the energization switch 51 is operated, by sending a signal from the ultrasonic oscillator 50 to the ultrasonic vibrator 60 is attached to the back of the sign 10 at regular intervals to form an ultrasonic wave on the sign 10 surface. Thereby, the dust or foreign matter on the surface of the sign 10 flows to the floor with water.

이에 표지판(10) 상부에 솔라셀(30)를 각 표지판(10)에 공급하고, 솔라셀(30)은 충전기(40)에 항시 전원을 충전시키며, DC 충전기(40)는 통전 스위치(51) 가 작동될시 DC 충전기(40)에서 발진기(50)를 통해 초음파 진동자(60)를 작동시키며, 이때 DC전원은 Hz가 없어 초음파 진동자(60)가 작동되지 않는다. 이에 발진기(50)내에 DC 인버터를 장착하여 변위가 있는 전원을 초음파에 인가시켜 초음파 진동자(60)를 작동시키도록 구성하며, 발진기(50)를 통해 초음파 진동자(60)를 작동하도록 한다. Thus, the solar cell 30 is supplied to each of the signs 10 on the top of the sign 10, the cell 30 charges the power to the charger 40 at all times, and the DC charger 40 is the energization switch 51. When is operated when the ultrasonic vibrator 60 is operated through the oscillator 50 in the DC charger 40, at this time, the DC power source is not Hz because the ultrasonic vibrator 60 does not operate.

이에 표지판은 사계절 외부에 노출되어 대기의 온도변화에 민감하게 된다. 반면에 초음파 세척의 중요한 요소중의 하나는 피조물의 온도이다. 적절한 온도 범위내에 있어야만 캐비테이션의 강도가 좋아지고, 세척효과가 향상된다. 이에 표지판 전체 면적에 균일하게 열선(90)을 부착 초음파 효율을 높이도록 한다. As a result, the signs are exposed to the outside of the four seasons, making them sensitive to changes in the temperature of the atmosphere. On the other hand, one of the important elements of ultrasonic cleaning is the temperature of the creation. Only within the proper temperature range, the cavitation strength is improved and the cleaning effect is improved. In this way, the heating wire 90 is uniformly attached to the entire area of the sign to increase the ultrasonic efficiency.

또한, 초음파 진동자(50)를 설치 시, 비나 또는 새등에 의해 초음파 진동자(50) 연결부 등에 부하가 걸려 고장의 위험이 있다. 이에 표지판 커버(91)를 만들어 외부 노출에 의한 고장이나 위험성을 줄이도록 한다. In addition, when the ultrasonic vibrator 50 is installed, a load may be applied to the connection portion of the ultrasonic vibrator 50 due to rain or leaking, which may cause a failure. This is to create a sign cover 91 to reduce the risk or failure caused by external exposure.

도 3 과 도 4 는 본 발명 표지판 자동 세척장치의 제2실시예를 보인 것으로서, 표지판 위에 방향 지시를 알리기 위해 도장한 면을 가지고 있으며, 이 도장면은 절연성(10)을 가지고 있으며, 표지판 상하부에 끝을 피복 벗긴 전선을 절연면에 통전스위치(51) 부착시킨다. 이후 진동 완충제인 고무판(70)을 연결하고, 평소에는 초음파 진동자(60)를 작동 시킬 수 있는 통전 스위치(51)가 통전이 되지 않아, 작동하지 않다가 비나 기타 도장면에 물기가 촉촉이 졌어 통전이 되어 통전스위치(51)가 작동되면, 표지판(10) 뒤쪽에 일정한 간격으로 부착되어 있는 초음파 진동자(60)로 초음파 발진기(50)에서 신호를 보내주어 표지판(10) 표면에 초음파를 형성시킨다. 이에 의해 표지판(10) 표면에 묻은 먼지나 이물질이 물과 함께 바닦으로 흘러 떨어지도록 한다. 3 and 4 shows a second embodiment of the automatic sign cleaning device of the present invention, and has a surface painted to indicate a direction indication on the sign, this painted surface has an insulating (10), the upper and lower signs Attach the bare wire to the insulation switch 51 on the insulating surface. After the rubber buffer 70 is connected to the vibration buffer, and the energization switch 51 that can operate the ultrasonic vibrator 60 is usually not energized, the water does not work, but the moisture on the rain or other painted surface is energized When the energization switch 51 is operated, by sending a signal from the ultrasonic oscillator 50 to the ultrasonic vibrator 60 is attached to the back of the sign 10 at regular intervals to form an ultrasonic wave on the sign 10 surface. Thereby, the dust or foreign matter on the surface of the sign 10 flows to the floor with water.

이에 표지판(10)에 AC전원(80)을 각 표지판(10)에 공급하고, AC전원(80) 공급시 AC전원(80)을 DC 전원(82)으로 변환하여 발진기(50)를 통해 초음파을 작동하도록 한다. In this case, the AC power supply 80 is supplied to each sign 10 at the sign 10, and when the AC power 80 is supplied, the AC power 80 is converted into the DC power 82 to operate the ultrasonic wave through the oscillator 50. Do it.
