Description
본 고안은 위성안테나의 반사판크기 조정장치에 관한 것으로, 보다 상세하게는 인공위성으로부터 전송되는 위성방송전파를 수신하는 위성안테나에 대한 반사판의 크기를 최적의 전파수신이 가능하도록 조정할 수 있도록 하는 위성안테나의 반사판크기 조정장치에 관한 것이다.The present invention relates to a reflecting plate size adjusting device of a satellite antenna, and more particularly, to a satellite antenna for adjusting the size of a reflecting plate for a satellite antenna receiving satellite broadcasting waves transmitted from a satellite to enable an optimal radio wave reception. It relates to a reflector plate size adjusting device.
주지된 바와 같이, 텔레비전방송국으로부터 전송된 텔레비전방송전파를 인공위성을 중계국으로 하여 지상에 전송시키도록 함에 의해 그 수신적용범위를 보다 더 광범위화한 위성방송방식이 채용되고 있는 바, 이러한 위성방송방식에 따라 전송되는 텔레비전방송전파를 선국하여 재생하기 위한 위성방송텔레비전에서는 해당 인공위성으로부터 전송되는 GHz단위의 위성방송전파에 대해 최적의 수신감도를 갖추고서 수신받기 위한 위성안테나가 설치된다.As is well known, a satellite broadcasting method is adopted in which a wider coverage range is adopted by transmitting a television broadcast signal transmitted from a television broadcasting station to the ground as a relay station. In satellite broadcasting television for reproducing and reproducing television broadcast waves transmitted accordingly, a satellite antenna for receiving reception with optimal reception sensitivity is provided for satellite broadcasting waves transmitted in the GHz unit.
이러한 위성방송텔레비전에 적용된 위성안테나는 도 1에 도시된 바와 같이, 그 설치장소에 따라 길이의 조정이 가능한 폴(2)에 접속된 원형상의 반사판(4)이 설치되고, 그 반사판(4)의 하단으로부터 연장되어 해당 반사판(4)의 정면과 대면하도록 설치된 전파수신부(6)가 설치된다.As shown in FIG. 1, a satellite antenna applied to such a satellite broadcasting television is provided with a circular reflector 4 connected to a pole 2 whose length can be adjusted according to its installation location. An electric wave receiver 6 is provided which extends from the lower end to face the front of the reflector 4.
동 도면에 따르면, 상기 원형상의 반사판(4)이 인공위성을 중계국으로 하여 전송하는 위성방송전파를 유기하여 반사시키게 되면, 그 반사판(4)과 대향하는 상기 전파수신부(6)측에서 반사되는 위성방송전파를 수신받아 LNB측으로 인가할 수 있도록 되어 있다.According to the figure, when the circular reflecting plate 4 induces and reflects the satellite broadcasting electric wave transmitting the satellite to the relay station, the satellite broadcasting reflected by the radio wave receiving unit 6 facing the reflecting plate 4 is reflected. It receives radio waves and can apply them to the LNB side.
하지만, 이러한 위성방송텔레비전에 채용되는 위성안테나에 있어서는 인공위성과의 수신거리가 상대적으로 멀거나 미약한 위성방송전파를 정상적으로 수신받고자 하는 경우에, 폴(2)의 길이조정이 가능하도록 되어 있지만 원형상으로 이루어진 반사판(4)의 구경이 고정적이기 때문에, 최적의 수신효율을 달성하기가 어렵게 된다는 단점이 있다.However, in the satellite antenna employed in such a satellite broadcasting television, the length of the pole (2) can be adjusted in the case of receiving a satellite broadcasting radio wave having a relatively long distance or a weak reception distance from the satellite. Since the aperture of the reflector plate 4 is fixed, it is difficult to achieve an optimal reception efficiency.
따라서, 본 고안은 상기한 사정을 감안하여 이루어진 것으로, 위성방송텔레비전에 채용되는 위성안테나에서 반사판의 크기를 방송전파에 대한 최적의 수신범위에 적당하게 용이한 조정이 가능하도록 하는 위성안테나의 반사판크기 조정장치를 제공하는데 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and the reflector plate size of the satellite antenna enables the antenna antenna employed in the satellite broadcasting television to easily adjust the size of the reflector to an optimal reception range for broadcast waves.

The pinion gear 14 is engaged.
이어, 상기한 바와 같이 이루어진 본 고안의 동작에 대해 도 3을 참조하여 상세히 설명한다.Next, the operation of the present invention made as described above will be described in detail with reference to FIG. 3.
먼저, 위성방송텔레비전의 방송전파 수신용으로 채용되는 위성안테나에서 전파수신부(6)를 통해 인공위성으로부터 전송되는 위성방송전파를 수신받는 경우에, 모터구동수단(도시되지 않음)의 구동에 의해 모터(16)가 정회전하게 되면 피니언기어(14)와 상호 치합된 제 1 및 제 2랙기어(12A,12B)가 상호 반대방향으로 기어조작되면서 제 1 및 2이동부재(10A,10B)를 상호 반대방향으로 이동시킴에 따라, 그 제 1 및 2이동부재(10A,10B)와 결합된 제 1 및 제 2이동반사판(8A,8B)이 펼쳐지게 되면서 반사판의 전체적인 크기가 증가된다.First, in the case of receiving satellite broadcast waves transmitted from the satellite through the radio receiver 6 in the satellite antenna employed for receiving broadcast waves of the satellite broadcast television, the motor may be driven by driving the motor driving means (not shown). When 16) rotates forward, the first and second rack gears 12A and 12B meshed with the pinion gear 14 are geared in opposite directions, and the first and second moving members 10A and 10B are opposite to each other. By moving to the first and second movable reflector plates 8A and 8B coupled with the first and second movable members 10A and 10B, the entire size of the reflector is increased.
