Device for automatic water supply in the irrigation system

 

(57) Abstract:

Usage: water supply to the irrigation system or watering gardens. The inventive device includes a reservoir for water, drain and inlet pipes installed in the tank shut-off body and the rocker with the evaporator and managing cargo at the ends. Managing cargo placed in the upper part of the tank and the shut-off body provides a floating labyrinth chamber cavity through which the input channel connected to the cavity of the tank, and through the output channel from the drain pipe, while the labyrinth camera has the ability to swing the height of the tank and communicating with the managing cargo. The invention will provide relief device service, as well as greater sensitivity to the need for watering. 1 C.p. f-crystals, 1 Il.

The invention relates to agriculture and can be used to supply water to the irrigation system and watering gardens.

As a prototype of the selected device to automatically supply water to the irrigation system that contains a water tank with a drain pipe, a closed tube is connected via a lever mechanism with karamitroglou is the need for much effort to open the drain plug, as it requires to overcome the pressure of a column of water equal to the height of the water level in the tank.

To obtain sufficient strength of the opening of the tube must evaporation of large amounts of water from the evaporation tray, resulting in large time intervals between two irrigations.

In addition, when the opening of the tube simultaneously with the release of water in the irrigation system starts at a special tube to fill the evaporation tray, which, in turn, will lead to a gradual closing of the tube, i.e., the consumption of water during the irrigation constantly decreasing.

This complicates the control device reduces the sensitivity to the need of irrigation, i.e., reduces its operational capabilities.

The aim of the invention is to facilitate maintenance of the device and increased sensitivity to the need for watering.

This goal is achieved by the fact that the device containing the water tank with overflow pipe, a stop valve installed in the tank, and a yoke, the ends of which is placed the evaporator and managing the cargo, according to the invention, managing cargo placed in the upper part of the tank and the shut-off body is made in in the tank and communicating with the managing cargo in its upper position, when this cavity labyrinth of chambers are connected through the input channel with the cavity of the tank, and through the output channel from the drain pipe. The evaporator is equipped with a tray for collecting rainwater.

If the labyrinth chamber is filled with water, it is afloat and doesn't let water out of the tank, and if water gets in the labyrinth the camera, it loses buoyancy and sinks and does not prevent water from siphoning out of the tank. The buoyancy of the labyrinth chamber can be adjusted so that enough will be a small effort on the part of the control of the load so that it is exposed to water.

The drawing shows a General view of the device.

The device comprises a reservoir 1 for a water inlet 2 and the drain 3 nozzles mounted inside the tank shut-off body. On the side wall of the tank in the upper part of the hinge is mounted to the yoke 4, one end of which is mounted managing the load 5, and the other evaporator.

The evaporator consists of the evaporation chamber 6 is mounted in its side walls of the crossbar 7, on which are fixed Batiste wicks 8.

The locking body 8 is a labyrinth chamber 11, imaus, thanks to the locking body has the ability to swing in a vertical plane with extreme positions on the tank bottom and in the upper part, where the labyrinth chamber 11 is in contact with the managing cargo 5.

On the intake pipe 2 has a valve-float 13. From the bottom of the discharge pipe 3 is allocated tube 14 to fill the evaporator.

The evaporator has a tray 15 for collecting rainwater, which flows into it. In the side wall of the evaporation chamber 6 has openings 16 for draining the excess water.

In the upper part of the tank 1 has a stopper 17 of the regulations governing cargo 5.

The device operates as follows. In the initial position the tank 1 is empty, the labyrinth, the camera 11 is in its lower position (shown dotted), evaporation chamber 6 is filled with water to the specified level and outweighs the load 5, which in the initial position abuts against the stopper 17.

When filling the water tank 1 with water through the inlet pipe 2 and the valve-float 13 cavity "and" labyrinth chamber 11 water will not be filled due to the fact that its buoyancy is adjusted so that the upper part of the inlet channel 9 was higher than the level "ptx2">

Stopping water supply to the tank 1 is provided with valve-float 13 which can be adjusted so that the water level with a sufficient degree of accuracy was the way in which the labyrinth chamber 11 will be in the area of reach of the steering cargo 5.

As the evaporation of water from the evaporation chamber 6, its weight decreases. As a result, the rocker arm 4 is rotated, the load 5, acting on the labyrinth chamber 11, forcibly utaplivaet it so that the upper part of the inlet channel 9 will be below the water level in the tank 1. Water flows into the cavity "a" labyrinth chamber 11, under the action of its weight off the body loses buoyancy and sinks to the bottom position. Under the action of the water pressure in the tank will begin its outflow through the labyrinth chamber 11, the output of the channel 10 and the connecting flexible hose 12 to the drain pipe 3. Drain all water from the tank 1, for example, in irrigation, or any other distribution system 18. The air trapped between the remnants of water in the irrigation system and a new portion merging water is discharged through the tube 14. As the upper part of this tube is below the top water level in the tank 1, at the beginning of discharge of the water on neeley chamber is removed through the holes 16.

After draining the water from the tank 1, its remains are removed from the cavity "a" labyrinth chamber 11 due to the siphon effect created by a drain pipe 3.

After lowering the water level in the tank 1 valve-float opens and begins to feed the next portion of water. To ensure that there is a complete draining of the water from the tank 1, the flow of water going to drain through the pipe 3, should be significantly greater than the inflowing water flow through the valve is a float 13.

After emptying the labyrinth chamber 11, the system comes to its original position, and the cycle repeats.

The inclusion of the water drain may be blocked by increasing the evaporation chamber 6 rain water collected in the tray 15.

Because the effort of embedding labyrinth chamber 11 is adjusted by changing its buoyancy, it can be set according to the value of much lower value than that required to lift the drain plug in the prototype, where necessary to overcome the pressure of a water column in the tank.

The system has the ability to control the time interval between drops of water from the reservoir due to changes in shoulder application weight evaporation chamber.

The same is Bladet greater compared to the prototype sensitivity to the need for irrigation, which is required, for example, during the growth of water-loving crops.

FIELD: irrigation systems for automatic irrigation of plants on restricted areas.

SUBSTANCE: apparatus has accumulation reservoir with bottom opening closed with valve, auxiliary reservoir, two float valves, one of said valves being designed for feeding water to accumulation reservoir and other valve serving for cutting-off said feeding process. Valve floats are positioned within auxiliary reservoir positioned lower than bottom of accumulating reservoir and connected through flexible pipelines to hermetically sealed reservoirs having porous bottoms and embedded in soil. Drawing of water by soil through said bottoms results in reduction of water level within auxiliary reservoir. Float valves are opened and water is delivered through one of said valves into accumulating reservoir. On reaching of predetermined water filling level, discharge opening valve is opened and water is delivered into low-pressure irrigation system and through other float valve into auxiliary reservoir. Increase in water level within accumulation reservoir cuts-off feeding of water into this reservoir. During operation of high-pressure irrigation system, functioning of apparatus is regulated by filling of accumulation reservoir to certain small volume and stabilized by means of detachable reservoir adapted to be mounted on accumulation reservoir and having horizontal partition walls.

EFFECT: increased efficiency and enhanced reliability in operation of apparatus.
