Abstract
The utility model discloses a device for controlling the automatic periodic work of the sprinkling irrigation system. A solenoid valve, a frequency change oscillator and a counting control circuit are added on the water supplying pipeline of the existing sprinkling irrigation system. The frequency change oscillator is used as the clock pulse source of a counter, and forms an ultra long period oscillator together with the counter, and the output signal of the counter is also the controlling signal outputted by the ultra long period oscillator; the signal drives a relay, and the relay controls the solenoid valve of the water supplying pipeline of the sprinkling irrigation system; the solenoid valve is opened when the counter outputs high level, the water supplying pipeline is opened, and the sprinkling irrigation system begins to work; the solenoid valve is closed when the counter outputs low level, the water supplying pipeline is closed, and the sprinkling irrigation system is stopped.
Description
The utility model relates to a kind of device of controlling the unlatching of sprinkling irrigation system automatic cycle and stopping, being particularly useful for green house flowers and vegetables in short-term, the batch (-type) automatic sprinkling system controller that replenishes of moisture repeatedly.
At present, known sprinkling irrigation system is a continuous schedule, in case open, promptly keeps the sprinkling irrigation duty, and its advantage is stable, lasting, need not manual intervention, be suitable for the big crop of water requirement.But little to water requirement and must constantly keep the skin wet crop, as the flowers " poinsettia " of green house cultivation, the cultivation initial stage requires every interval sprinkling irrigation in 5 minutes 10 seconds, then feels very inconvenient, even is difficult to realize.
The purpose of this utility model provides a kind of controller, and it can open and close automatically sprinkling irrigation system according to setting cycle, realizes the batch (-type) automatic irrigation.And sprinkling irrigation and intermittent time can be regulated respectively, are independent of each other.
The purpose of this utility model is achieved in that the clock source of making counter with a variable frequency oscillator, a common composition oscillator ultra-long period, the output signal of counter drives relay after driving, the magnetic valve on the relay control sprinkling irrigation system water supply line.Magnetic valve is opened when counter output high level, and water supply line is open-minded, the work of sprinkling irrigation system water spray; Solenoid closure when the counter output low level, water supply line is closed, and stops sprinkling irrigation.
Adopt such scheme, only need on former water supply line, set up a magnetic valve, outside join a vibration counter controling circuit and can realize the batch (-type) automatic irrigation, therefore simple in structure.
Describe the working condition of the utility model device in detail below in conjunction with drawings and Examples.
Fig. 1 is the circuit theory diagrams of batch (-type) automatic sprinkling system controller.
