Description

The invention relates to irrigated agriculture and can be used in irrigation systems, which do not require the consumption of additional energy to control the irrigation regime.

The aim of the invention is to improve the conditions for the development of plants by providing watering plants with heated solar energy water.

The drawing is shown. the proposed device, a General view.

A device for automatically supplying water to an irrigation system comprises a supply tank 1 with a water supply 2, a shutoff member 3 and an exhaust pipe 4, a storage device 5 and a rocker 6, at the ends of which an evaporator 7 and a control load are placed 8. The rocker 6 swings on an axis 9, reinforced on the base 10, it is equipped with a latch consisting of a spring-loaded stop 11 and a fixing groove 12, and is connected to the locking element 3 using a system of levers 13. The accumulator 5 is the receiving tank of the irrigation system 14. The evaporator 7 is hydraulically connected dinene with the upper part of the horizontal section of the exhaust pipe 4 using the tube 15.

The supply tank 1 is equipped with an additional tank 16 located below the shut-off element 3 and hydraulically connected to the evaporator 7 by an output channel 17 with a valve 18, which is mechanically connected to a temperature-sensitive element 19, for example a bellows, through a buffer spring 20 and a valve 21 with a control handle 22. The heat-sensitive element 19 is mounted on the bracket 23, and the handle 22 of the crane 21 is connected to one of the levers 13 through a forked lever 24, rotating on the axis 25.

Thermosensitive element. can be made in the form of a bimetallic diaphragm.

The established mode of supplying water to the irrigation system 14 is supported by periodically changing the amount of water in the evaporator 7 by entering a given portion of water from the supply tank 1 and its natural evaporation to a predetermined level.

When filling the supply tank 1 with water 2, the temperature of which is lower than the set value, for example below 15–20 ° C, the water does not enter the irrigation system immediately, but after it has time to heat up with the energy of sunlight or due to the heat of the surrounding air.

The device operates as follows.

In the initial position, the supply tank 1 and the evaporator 7 are empty. The locking ₅ body 3 and the valve 21 are open. The bellows 19 (or bimetallic diaphragm) under the influence of ambient temperature maintain the valve 18 in a closed state.

When filling the supply tank 1 'θ with warm water through an open shut-off element 3, the water enters the exhaust pipe 4 and then into the irrigation system 14 for watering the plants. At the same time, part of the water through the tube 15 enters the evaporator 7. Water, having filled the evaporator 7 to a predetermined level, overcomes the force of the control load 8, the rocker 6 turns, the stop 11 enters the fixing groove 12, the locking element 3 is tightly pressed against the saddle and ²⁰ is terminating access of water to the irrigation system 14. The next water supply to the irrigation system occurs upon evaporation of water in the evaporator 7 to a predetermined value.

When filling the supply tank 1 25 with cold water, water · first enters the tank 16, the bellows 19 opens the valve 18, and the water quickly fills the evaporator 7 through the open valve 21 and the channel 17, before it even gets into the irrigation system. The water-filled evaporator 7 overcomes the force of the control load 8, the rocker 6 rotates and the shut-off element 3 closes. When moving the levers 13, the forked lever 24 also rotates around the axis 25, and the lever 21 closes the lever 21, the access of water to the evaporator 7 is stopped. 35 In most cases, there is enough time before the next supply of water to the irrigation system so that the water in the supply tank is sufficiently heated. While the water is heating, bellows 19 remains compressed, valve 18 is open. When the water in the evaporator 7 evaporates to a predetermined level, the control load 8 turns the rocker 6, the shut-off element 3 and valve 18 open. But since the diameter of the channel 17 is much larger than the diameter of the tube 15, ⁴⁵ , the evaporator 7 again quickly fills with water through the tube 17, the shut-off element 3 closes.

When heating the water in the supply tank 1 due to solar energy, the valve 18 5Q closes under the influence of bellows evaporator 7 is filled only through the tube 15 at the next water supply to the irrigation system.
