The present invention relates to automatic heat-retaining water supply equipment for a ranch, configured to receive supply of water by a water supply means. The automatic heat-retaining water supply equipment for a ranch comprises: a hollow housing which is formed in a hexahedral shape with an upper side opened a water tank which is formed in a shape to receive water with an opened upper portion, and is inserted and coupled to the inner side of the housing, in which a water inlet pipe and a drainpipe connected to the water supply means are vertically connected to selectively supply or drain water from the inner bottom surface of the water tank by a user, in a lower portion thereof and a control means which is installed on an outer wall of the housing, and electrically controls water to be supplied or drained from the water inlet pipe and the drainpipe of the water tank. The purpose of the present invention is to provide the automatic heat-retaining water supply equipment for a ranch with excellent durability, which automatically supplies fresh water to a barn for livestock at all times and, in particular, smoothly supplies warm water in winter, prevents freezing, and suppresses corrosion.COPYRIGHT KIPO 2016본 발명은 목장용 자동 보온 급수기에 관한 것이다.본 발명은 급수 수단에 의해 물을 공급받도록 구성된 목장용 자동 보온 급수기에 있어서, 내부가 중공되며, 상측이 개방된 육면체 형상으로 이루어진 하우징 상부가 개방된 수용형태로 이루어지며, 상기 하우징의 내측에 삽입 결합되고, 하부에는 사용자의 선택적으로 내측 바닥면으로부터 물을 공급 또는 배수하도록 상기 급수 수단과 연결된 입수관과, 배수관이 각각 수직하게 연결된 수조 및 상기 하우징의 외벽측에 설치되고, 상기 수조의 입수관 및 배수관으로부터 물이 공급 또는 배수되도록 전기적으로 제어하는 제어 수단을 포함하여 이루어진 목장용 자동 보온 급수기를 제공한다.
