Description

The invention relates to irrigated agriculture and can be used in closed agricultural structures, such as greenhouses, greenhouses and greenhouses.

The aim of the invention is to improve the reliability of operation and to save water by providing a predetermined irrigation mode.

Fig. 1 shows the general scheme of the device; in fig. 2 - additionally a device locking device with a fault indicator in FIG. 3-5 — a storage device in the filled, intermediate, and empty states, respectively.

The device for automatically supplying water to the irrigation system 1 comprises a supply line 2 connected by pipelines 3 to 5 with a shut-off member 6, a storage tank 7 and an expansion tank 8. The pipeline A at the outlet to the storage tank 7 is provided with a water supply limiter 9. In the accumulator 7, a locking member 10 is installed in the form of a self-closing valve 11, made, for example, in the form of a rubber bulb and mated to the seat 12. The valve has a stem 13 with an emphasis 14 located inside the guide sleeve 15, which in the lower part has an opening free passage of the rod 13, and in the upper - the flange 16, and connected to the rod 17 of the float 18 by the sleeve 19. The guide sleeve 15 freely moves in the support tube 20. The limiter 9 is made in the form of a valve with a handle 21 for regulating the water supply to the accumulator 7 ( figure 1) or in the form of a jet with an adjustable hole (Fig. 2).

The proposed device is equipped with

in the upper part of the accumulator 7, an opening 22 with a groove 23 connected to one shoulder of the U-shaped tube 24. In the second arm of this tube 24 a floating signal rod 25 is placed. The groove 23 is hydraulically connected to a vertically movable cup 26, with a drain cock 27. The same drain cranes 27 have a U-shaped tube 24. The cup 26 is mechanically connected by a pull 28 to a locking member 6, spring loaded 29 and provided with a lock 30. The device is equipped with a scale 31 of the critical water level in the accumulator.

The scale is applied on a separate probe or on the guide rod of the float 18.

The convenience center is located on the outer wall of the accumulator; there is a table or

the corresponding reset schedule

water in the reservoir, depending on the critical level of water in the reservoir.

The device works as follows.

in a way.

In the initial positions, the locking body 6 in the supply line 2 is closed, the water supply restrictor 9 is closed, the valve 11 under the action of its weight. Pushed to the seat 12, the sleeve 15 with the float 18 also under the action of its own weight by the collar 16 rests on the support tube 20.

To bring the device into working condition, it is necessary to set the float 18 to the position corresponding to the specified critical water level in the accumulator 7, according to the specified water supply cycle for irrigation, use the table to determine the water flow from the supply limiter 9. For example, for one irrigation it is necessary to feed 80 l of water into the irrigation system and water it once, then through the restrictor water flows to the reservoir 55.5 ml / min. The flow rate is checked by the measuring tank and the stopwatch, then when filling the accumulator 7 to the level when the float 18 begins to sink into

WATER} float 18 with the guide sleeve 15 against the stop 14 of the rod 13 will lift the valve 11. Through the gap between the valve 11 and the cross, 12 (Fig. 3), water rushes into the pipeline 5, an ejector valve 11 is generated (Fig. 6) and valve 11 is freely raised upwards. After the accumulator is emptied, the valve 11 freely lowers onto the saddle 12 (Fig. 5), the sleeve

15 does not oppose the lowering of the valve 11, since as the water level in the accumulator 7 drops, the float 18 goes down and the sleeve 15 takes the lower position, In the accumulator 7

water again accumulates for the next irrigation.

In the event of a malfunction of the device, for example, a loss of buoyancy of the float 18, when the water level reaches the opening 22 (Fig. 2), water passes through the chute 23 to the tube 24 and the signal rod 25 rises up due to its rise.

Noah forces, and then water begins to enter the cup 26, When the weight of the stack at 26 overcomes the opposing force of the spring 29, the latch 30 and the locking member 6, the latch 30 of the opera beats, and the glass sharply closes the frontal organ 6. If the long time failure , a portion of the water in the glass evaporates, the spring 29 again lifts the glass

 26 and the locking member 6 is opened only for the time required to replenish the cup 26. The signal rod 25 can be combined with a 5 point device to transmit a malfunction signal to the central repair center. After elimination of the malfunction, water from the U-shaped tube 24 and from the glass 26 is drained through the drain cocks 27.
