Description

The invention relates to irrigation systems and can be used, in particular, for automatic watering of plants in garden plots and gardens.

A device for automatic watering of plants is known, containing a tank with a siphon installed in it, a launching tank with a drive to return it to its original position and an evaporation tray (RU 2187927 C2, 08.28.2002). The evaporation tray is mounted on a hinge and is equipped with a lever controlling the latch of the starting capacity and an overflow nozzle with an adjustable overflow height. A magnetic latch is installed at one end of the evaporation tray, and a counterweight with adjustable position is installed at the other. The device is also equipped with a supply line, on which the valves for supplying water to the supply tank and the starting tank are installed, and a shut-off float valve. The invention allows for the inclusion of irrigation depending on weather conditions.

The disadvantages of the device are the complexity of the siphon charging mechanism and the dependence of the irrigation rhythm on the rate of water evaporation in the evaporation tray.

The technical result achieved by the implementation of this invention is to ensure the rational use of water for watering plants.

The specified technical result is achieved by the fact that the device for automatic watering of plants, including a feed tank with a siphon installed in it at the trigger point, a starting tank and an evaporation tray, according to the invention is equipped with a locking lever valve and overflow tube, the starting tank has the shape of a bucket and is made with the possibility free rotational-vibrational movement around the hinge axis between the two stops, the evaporation tray is mounted on springs worn on pins fixed On the upper edge of the wall of the supply tank, on the evaporation tray, a pusher is fixedly connected pivotally to the lever of the shut-off valve, a valve regulating the flow of water is installed at the inlet to the shut-off valve, and the overflow pipe is connected to the irrigation network.

The drawing schematically shows the proposed device for automatic watering of plants.

A device for automatic watering of plants contains a supply tank 1, in which a siphon 2 is installed at the activation mark, the output 3 of which from the supply tank is connected to the irrigation system. On the supply tank 1, a starting container 7 is also installed, freely rotating around the hinge axis 8, a shut-off valve 10 connected via a lever system 5 and 6 with an evaporation tray — a cover 4 mounted on springs 12 worn on pins 13 and an overflow pipe 14 Between the shut-off valve 10 and the supply line, a valve 11 for controlled supply of water to the supply tank is installed. The launch container is a bucket, the side walls of which are triangular in shape.

The device operates as follows. Water required for watering the plants enters the device from the supply line. First, water accumulates in the supply tank 1, where it is heated to ambient temperature, which is important for creating comfortable conditions for heat-loving vegetable crops.

The rate of water accumulation is determined by the frequency of irrigation and is set by the control valve 11. The process of water accumulation in the tank proceeds as follows. Water from the control valve 11 first enters the shut-off valve 10, which is always open during normal operation, and then into the starting tank 7. The center of gravity and the axis of the suspension 8 of the starting tank 7 are selected in such a way that after each filling with water it automatically caps and empties , after which it automatically returns to its original state to receive the next portion of water. This continues until the water level in the supply tank 1 reaches the upper level of the siphon 2. As soon as this level is reached, the siphon is charged and started with the last portion of water. Water through a siphon enters the distribution network 3 and the plants are irrigated.

When the water level in the tank reaches the lower end of the siphon, the siphon is discharged and watering stops. A new cycle of filling the tank with water begins.

To ensure reliable operation of the starting capacitance 7, its cyclic rotational-vibrational movement occurs only between the limiters 9.

Device operation during and after rain. During rain, rainwater accumulates in the evaporation tray lid 4. The mass of this water through the pusher 5 puts pressure on the lever 6 of the shut-off valve 10, which closes the access of water from the supply line.

After the rain stops after a certain time, which is achieved by choosing the depth of the tank lid, the rainwater evaporates. Under the action of the springs 12, the cover of the supply tank rises and pulls the pusher 5, lever 6 and valve 10, opening the way for the flow of water into the supply tank 1.

Thus, the rhythmic watering of plants during rain automatically stops, and after the rain stops again automatically resumes.

In case of emergency, the device has an overflow pipe 14, through which water enters the irrigation network.
