The invention discloses an intelligent
water supply device for
ecological agriculture. The intelligent
water supply device comprises a water tank, an
illuminance sensor, a PLC (
programmable logic controller), a first water pump, an
electromagnetic valve, a soil layer and flow guide cylinders, wherein a water inlet is formed in the upper part of the exterior of the water tank, a temperature sensoris arranged on the left side of the exterior of the water tank, the PLC (
programmable logic controller) is arranged on the left side of the exterior of the water tank, a water outlet
pipe is arrangedon the upper right side of the exterior of the water tank, the first water pump is arranged under the end part of the water outlet
pipe, the
electromagnetic valve is arranged on the water outlet
pipe,inclined plates are arranged on the right sides of the exteriors of enclosing walls, the flow guide cylinders are arranged at the upper part of the interior of the soil layer, and connecting pipes are arranged under the end parts of the flow guide cylinders and communicate with the water tank through a water inlet pipe. According to the intelligent
water supply device, the water tank, the
illuminance sensor, the temperature sensor, the PLC (
programmable logic controller), slopes, the flow guide cylinders and the water inlet pipe are arranged, so that the problems that intelligent water supplycannot be realized, rainwater cannot be collected when it rains, and then resources are wasted can be solved.
