The invention provides an automatic constant-temperature internal circulation artificial incubation device which comprises an incubation pond, a
water treatment tank is arranged on one side of the incubation pond, a water suction header
pipe is arranged in the
water treatment tank, and a plurality of suction pipes communicated with the water suction header
pipe are arranged at the bottom of the incubation pond. A water filtering device, a disinfection box and a heating box which are sequentially communicated are arranged in the
water treatment tank, the water suction header
pipe is communicated with the inlet end of the water filtering device, a plurality of
ultraviolet disinfection lamp tubes are arranged in the disinfection box, and an
electric heating tube is arranged in the heating box; a circulating water pump is arranged in the water treatment tank, the inlet end of the circulating water pump is communicated with the outlet end of the heating box, the outlet end of the circulating water pump is communicated with a circulating header pipe, the upper end of the
hatching pond is slidably connected with a plurality of water spraying pipes with holes in the lower portions, and each water spraying pipe is communicated with the circulating header pipe through a connecting hose.
Hatching is conducted in a constant-temperature internal circulation mode, the
water temperature can be accurately and evenly controlled,
water quality can be effectively purified in the circulation process, and fry are prevented from getting ill.
