Description

유리세척 기능을 갖는 ＣＣＴＶ 카메라 하우징{A Housing For CCTV Camera Having Function of Cleaning Glass}CCTV Camera Having Function of Cleaning Glass

본 발명은 유리세척 기능을 갖는 CCTV 카메라 하우징에 관한 것으로서, 보다 상세하게는 하우징 본체의 전면에 설치되는 유리의 굴곡을 보상하도록 코팅층을 형성하고, 유리의 적어도 일측면에 진동수단을 설치하여 유리면에 주기적으로 진동을 가함으로써 유리면을 세척할 수 있도록 하는 CCTV 카메라 하우징에 관한 것이다.The present invention relates to a CCTV camera housing having a glass cleaning function, and more particularly, to form a coating layer to compensate for the curvature of the glass installed on the front of the housing main body, by installing a vibration means on at least one side of the glass to the glass surface The present invention relates to a CCTV camera housing capable of cleaning the glass surface by periodically applying vibration.

CCTV 카메라는 도로상의 불법 주차, 방범 등의 목적으로 광범위하게 사용되고 있다.CCTV cameras are widely used for illegal parking and crime prevention on roads.

일반적으로 CCTV 카메라는 장치를 보호하기 위한 목적으로 별도의 하우징 내부에 부착되어 필요한 위치에 설치되나 도로나 제철소, 시멘트공장, 화학공장 등과 같은 장소에서는 다량의 먼지나 유분과 같은 분진들이 공기 중에 부유하며 이러한 분진들은 시간이 경과됨에 따라 카메라 하우징 전면 유리부위에 안착하게 되어 카메라의 시야를 흐리게 하는 문제점을 갖게 된다.In general, CCTV cameras are installed inside a separate housing for the purpose of protecting the device and installed at the required location, but in places such as roads, steel mills, cement plants, chemical plants, etc., a large amount of dust or oil dust floats in the air. These dusts are settled on the front glass portion of the camera housing over time has a problem that obscure the view of the camera.

종래 CCTV 카메라 하우징의 유리를 세척하기 위한 기술에는 윈도우 브러쉬와 물 공급 장치를 소형으로 제작하여 부착한 경우가 있으나, 윈도우 브러쉬의 고무부분의 열화 또는 물 공급 장치에 물이 없을 때 브러쉬를 작동할 경우 유리면에 부착된 먼지나 유분으로 오염상태가 더욱 심해지는 경향이 있으며 물 공급을 위해 주기적으로 점검을 해야하고 물이 부족할 경우 물 보충을 해야하며 온도가 낮은 겨울에는 동파방지를 해야하는 등의 대책이 필요한 문제점이 있다.Conventional techniques for cleaning the glass of CCTV camera housings may be made by attaching a small sized window brush and water supply device. However, when the brush is operated when the rubber part of the window brush is deteriorated or there is no water in the water supply device. Dust or oil attached to the glass surface tends to be more contaminated and requires regular checks for water supply, replenishment when water is scarce, and measures to prevent freezing during low temperature winters. There is a problem.

한편, 국내등록특허 제10-0189288호에 따른 기류를 이용한 카메라 하우징 먼지 제거장치의 구조가 도 1에 도시되어 있다.On the other hand, the structure of the camera housing dust removing apparatus using the airflow according to the registered domestic patent No. 10-0189288 is shown in FIG.

도 1에 도시된 바와 같이, 상기 기류를 이용한 카메라 하우징 먼지 제거장치는 카메라 하우징(1)을 내벽(1a)과 외벽(1b)으로 된 2중벽으로 형성하여 내외벽(1a), (1b)사이에 공기공급로(4)가 구성되도록 형성하고, 공기공급로(4)의 선후 양단부에 내측에 필터(7)를 장착한 공기공급구(5)와 유리창(3)의 표면부에 도입된 공기분사구(6)를 각각 형성하며, 공기공급구(5)에 타이머(9)와 연결시킨 송풍팬(8)을 설치하여 송풍팬에서 공급된 기류에 의해 유리창의 전면의 먼지를 제거하도록 하는 기술이 제시되어 있다.As shown in FIG. 1, the camera housing dust removing apparatus using the airflow forms the camera housing 1 as a double wall consisting of an inner wall 1a and an outer wall 1b, thereby forming a gap between the inner and outer walls 1a and 1b. Air introduced into the surface of the glass window (3) and the air supply port (5) having the filter (7) mounted on both sides of the rear end of the air supply path (4). Forming the injection holes (6), the air supply port (5) is installed in the blowing fan (8) connected to the timer (9) to remove the dust on the front of the window by the air flow supplied from the blowing fan Presented.

그러나, 상기 기술은 구조가 복잡하고 설치비용이 많이 소요될 뿐 아니라 기류에 의한 먼지 세척에는 한계가 있다.However, the technique is complicated in structure and expensive to install, and there is a limit to cleaning dust by airflow.

또한, 국내특허공개 제2003-0083544호에 따른 종래 필름을 이용한 카메라 및 센서 하우징의 윈도우 클리닝 장치의 구조가 도 2에 도시되어 있다.In addition, the structure of the window cleaning apparatus of the camera and the sensor housing using a conventional film according to Korean Patent Publication No. 2003-0083544 is shown in FIG.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 일 실시예를 상세하게 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도 3은 본 발명에 따른 유리세척 기능을 갖는 CCTV 카메라 하우징의 구조를 도시한 단면도이다.3 is a cross-sectional view showing the structure of a CCTV camera housing having a glass cleaning function according to the present invention.

도 3에 도시된 바와 같이, 본 발명에 따른 유리세척 기능을 갖는 CCTV 카메라 하우징은 하우징 본체(10)의 내부에 카메라(20)가 설치되고 하우징 본체(10)의 전면에 유리부재(40)가 설치되어 있다.As shown in Figure 3, CCTV camera housing having a glass cleaning function according to the present invention, the camera 20 is installed inside the housing body 10 and the glass member 40 on the front of the housing body 10 It is installed.

하우징 본체(10)와 유리부재(40) 간에는 방수 고무 커버(30)가 개재되어 외부의 이물질이 하우징 본체(10) 내부로 침투하는 것을 방지하도록 되어 있다.A waterproof rubber cover 30 is interposed between the housing body 10 and the glass member 40 to prevent foreign substances from penetrating into the housing body 10.

유리부재(40)는 전면(외부를 향하는 면)의 표면이 편평하도록 투명재질의 코팅막(60)이 형성되어 있다. 코팅막(60)은 유리부재(40)의 표면이 평탄하지 않고 굴곡이 많은 점을 감안하여 표면을 평탄화하기 위한 것으로서, 일본 ACE사의 불소 수지 코팅제인 T-LON 또는 무기질 유리코팅제인 GS-600 등의 특수 코팅제가 사용될 수 있다.The glass member 40 is formed with a transparent coating film 60 so that the surface of the front surface (the surface facing outward) is flat. The coating film 60 is for flattening the surface in consideration of the fact that the surface of the glass member 40 is not flat and has a lot of bends. Special coatings may be used.

실험결과, 코팅막(60)이 없는 경우에는 유리부재(40)의 굴곡으로 인해 유리부재(40)에 진동을 가하더라도 유리부재(40)에 부착된 먼지나 수분 등이 제대로 탈거되지 않았으나, 코팅막(60)이 형성된 경우에는 먼지나 수분 등의 탈거율이 현저하게 상승됨을 알 수 있었다.As a result of the experiment, in the absence of the coating film 60, even if the glass member 40 is vibrated due to the bending of the glass member 40, dust or moisture attached to the glass member 40 was not properly removed, but the coating film ( When 60) was formed, it was found that the removal rate of dust, moisture, etc. was significantly increased.

진동수단(50)은 유리부재(40)의 후면 일측에 적어도 하나 이상 설치되며, 유리부재(40)에 진동을 가하여 유리부재(40)에 부착된 먼지 등의 이물질을 탈거시키는 기능을 수행한다. 본 실시예에서는 진동수단(50)으로서 브러쉬리스직류모터 2개를 유리부재(40)의 후면 상단 및 하단에 각각 설치하였으며, 이물질의 탈거력을 높이기 위해 브러쉬리스직류모터에 초음파가 인가되도록 하였다.Vibration means 50 is installed at least one side of the rear side of the glass member 40, and performs a function of removing the foreign matter such as dust attached to the glass member 40 by applying a vibration to the glass member (40). In this embodiment, two brushless direct current motors were installed at the upper and lower rear surfaces of the glass member 40 as the vibration means 50, and ultrasonic waves were applied to the brushless direct current motor in order to increase the detachment force of foreign substances.

도 4는 유리면에 진동을 인가하기 위한 회로 구성을 도시한 블록도이다.4 is a block diagram showing a circuit configuration for applying vibration to a glass surface.

도 4에 도시된 바와 같이, 진동회로는 초음파 펄스를 발생시키는 초음파 발생기(70)와 타이머(80), 타이머(80)에 동작 주기 및 동작시간을 설정하기 위한 시간설정 스위치(90)를 포함하여 구성된다.As shown in FIG. 4, the vibration circuit includes an ultrasonic generator 70 for generating ultrasonic pulses, a timer 80, and a time setting switch 90 for setting an operation cycle and an operation time in the timer 80. It is composed.

타이머(80)는 설정된 주기마다 동작하여 초음파 발생기(70)에서 발생된 초음파 펄스를 진동수단(50)에 인가하여 진동수단(50)이 동작시간 동안 진동하면서 유리부재(40)에 부착되어 있는 먼지, 수분 등의 이물질을 탈거시키게 된다.The timer 80 operates every set period to apply the ultrasonic pulse generated from the ultrasonic generator 70 to the vibrating means 50 so that the vibrating means 50 vibrates during the operation time and is attached to the glass member 40. , Foreign substances such as moisture are removed.

상기 실시예에서 하우징 본체(10)의 전면에 유리부재(40)가 설치된 경우를 예시하였으나 그 외에 투명재질의 합성수지가 사용될 수 있음은 물론이다.Although the glass member 40 is installed on the front surface of the housing main body 10 in the above embodiment, the synthetic resin of transparent material may be used.

또한, 본 실시예에서 코팅막(60)이 유리부재(40)의 전면에 형성되도록 하였으나, 후면에도 설치할 수 있음은 물론이다.In addition, although the coating film 60 is formed on the front surface of the glass member 40 in the present embodiment, it can be installed on the rear surface.

비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정이나 변형을 하는 것이 가능하다. 따라서 첨부된 특허청구의 범위는 본 발명의 요지에서 속하는 이러한 수정이나 변형을 포함할 것이다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention.
