The invention aims to solve the problem that existing
irrigation is not energy-saving enough, and discloses an energy-saving
irrigation device for water conservancy projects. The energy-saving
irrigation device comprises a first fastening screw, a first ejector rod, a first supporting frame, a first bottom plate, a first rocking
handle, a first
lantern ring, a first rotating shaft, a first
rotating disc, a positioning frame, a liquid outlet
pipe, a sleeve, a supporting plate, a rack, a first motor, a
rotating disc, a first rack, a second rack, a sliding rod, a guide groove, a spiral spring, afirst connecting ring, a mounting plate, a connecting bag, a second connecting ring, a pull
rope, a second
rotating disc, a second
lantern ring, a second rotating shaft, a second rocking
handle, a second supporting frame, a second fastening screw, a second ejector rod, a second bottom plate, a hammer block, a second motor, a first roller, teeth, a chain and a fourth rotating shaft. By moving a watering pipeline and detecting the
hardness of the ground, the
staying time of the device can be conveniently controlled according to terrains with different
hardness, the watering amount is controlled,and therefore reasonable irrigation is conducted, and more energy is saved.
