Automated irrigation system with low-pressure sprinkler machines circular steps is as follows.
Before the beginning of the growing season operator sets on cranes-setting device 31 of the speed of sprinkling machines, the CPU 14 will say sprinkling machines that will pour the relevant areas, the initial water content in the soil in the irrigated areas, biological factors irrigated crops and their irrigation.
During the growing period of the automatic weather station 15 calculates potential evapotranspiration of crops cultivated and transmits these readings of the CPU 14, which calculates evapotranspiration grown in the irrigated areas of agricultural crops. When reducing the calculated water content in the soil in the irrigated areas to the lower threshold of the optimum soil moisture, the CPU 14 sends a signal about the beginning of irrigation.
The operator engages the turbine 4, to the which rotates in the low-pressure pump 6, high-pressure pump 5, the generator 7 and then switches the CPU 14 in the automatic mode. The CPU 14 generates a package of short voltage pulses and pulse with more duration on the inclusion of DM, which serves to drive the three-way valve 12. The number of the pulse of long duration corresponds to the number of the first selected sprinkler (selected first irrigated land).
When applying voltage pulses to the coil of a three-way valve 12 switches and generates a pause interrupts the supply of high pressure water in the high pressure pipe 13. At each pause in the work management systems and hydraulic protection against accidents sprinkling machines 11 diaphragm actuator 19 switches the ratchet mechanism 17 one step. While long pause interrupts the supply water pressure in the high pressure pipe 13 to the selected pivot the pusher 18 ratcheting mechanism 17 off the first three-way valve 16 for a time sufficient for flushing water from the membrane actuator 21 through the orifice 20 and the first three-way valve 16. When this diaphragm actuator acts on the dip switch 22, which includes a second three-way valve 23, through which the water from the high pressure pipe 13 is fed into the line hydronamic 28 DM from accidents and power line 25 hydraulic actuators 26 sprinkling the machine.
With proper pivot Executive valves 29 line hydronamic 28 DM from accidents are closed, and the pressure of water supplied to the membrane actuator shut-off valve 24 and diaphragm actuator, hydrocele 30. The shutoff valve 24 is opened and water is supplied to the power line 25 hydraulic actuators 26. Sprinkling machine 11 starts to move.
At the same time, hydrocele 30 switches the hydraulic valve 10 at the input of the pivot opening. The valve 10 is opened, and water is fed into the feeding zone of the pivot 11. Sprinkling machine begins to water. Thus, the CPU 14 monitors the readings of the flow meter 8, the increase of water flow in low-pressure pipe 9 and secures the inclusion of the pivot.
At the approach to the "corner" sector, which also is watering the "corners"that are not captured by sprinkling machine, the sensor 39 can start to work through DM angular sector impact mechanism 38 connect impulse sprinkler apparatus 33 to the supply line of the hydraulic actuator 25, which includes a third three-way valve 32. The water from the supply line 25 of the hydraulic actuators is fed into the upper cavity hydropneumoaccumulator 34, the lower cavity which is filled with compressed air. After filling with water the upper cavity hydropneumoaccumulator his diaphragm 34 35 affects the dip is echanism switch 36, which opens the valve 37, and sprinkler unit 33 under the action of the energy of compressed air generates a pulse irrigation. After that, the membrane affects the two-position switching mechanism 36, which closes the valve 37, and the process of accumulation of water in hydropneumoaccumulator repeats, etc.
After passing through the angular sector sensor 40 interacts with the mechanism 38, which turns off the third three-way valve 32, the flow of water in impulse sprinkler apparatus 33 and watering "angle" stops and sprinkling machine continues watering of the site in normal mode.
In case of emergency (invalid bending water conveyance belt sprinkler) on the failed anchor trolley offers Executive valve 29, the water pressure in the line 28 hydronamic falls, shut-off valve 24 is closed, the water supply to the hydraulic actuators 26 and further bending water conveyance belt pivot stops. Hydrocele 30 switches the drive of the valve 10 to close the flow of water in water conveyance belt is stopped. The water flow in low-pressure pipe 9 is reduced, the CPU 14 detects the change of the readings of the flow meter 8 off sprinkler and gives an alarm to the operators who are going to repair the DM, and the CPU 14 at this time connects to stabilize R the vanishing water backup DM.
For inclusion in the next sprinkler CPU 14 calculates and submits the following package pulses with one pulse of long duration, the number of which corresponds to the number of the selected sprinkler, or the pulse of long duration, if DM connected serially to each other.
After issuance of irrigation on the plot (with the passage of DM circle irrigation and mining of time watering) CPU reapplies for the selected DM 11 in the high-pressure piping package pulses to interrupt the supply of pressure water. Reenabling the switching device 22 turns off the second three-way valve 23. Water supply in line hydronamic 28 from accidents and power line 25 of the hydraulic actuator 26 is terminated, sprinkling machine 11 stops, watering is stopped.
