The invention relates to the technical field of animal feeding equipment, in particular to an automatic water replenishing and metering
system for a zoo, which is mainly composed of a drawing type drinking water box main body, a protective shell, a weighing module, a
control unit and a water adding device. The drinking water box main body is designed to be of a drawable structure, so that a user can quickly take out the drinking water box to thoroughly clean the drinking water box, and drinking water
sanitation is ensured; the protective shell is arranged on the outer side of the pull-out type
water drinking box body, the pull-out type
water drinking box body can be effectively prevented from being damaged or polluted by animals, and then the service life of the
water drinking equipment is prolonged; through mutual cooperation of the weighing module and the
control unit, an automatic water adding function can be realized, so that manual intervention is reduced, and the feeding efficiency is improved; by arranging the weighing module, the
water volume in the pull-out type drinking water box body can be monitored in real time, it is ensured that the
water volume in the pull-out type drinking water box body is always kept within the set
water volume threshold value range, and then the situation that the water volume is insufficient or wasted is avoided.
