Abstract

Autonomous irrigation system The object of the invention is a system formed by a duct (2) in the form of a Gaussian bell, a buoy-shaped receptacle (4) being inserted in the highest part of the bell, in which the interior is placed a small duct (4a) also bell-shaped and has the same drain functions. The system is fixed to the upper and lower part of the tank by means of rope (6) or similar (irrigation activation axis). The tank (1) slowly fills up and when the water exceeds the level of the container (4), water enters the tank and a sudden subsidence that completely submerges the bell, allowing water to escape from the tank with little resistance. The system allows water to be driven at predetermined intervals and quantities, without the need for any other source of energy than the water entering the tank itself (1).

Description

Autonomous irrigation system (Dosing).

The state of the art in this regard, is what advanced enough to dose not only water, but Any product at any level or features. All modalities that exist in the current market have something in common (regardless of their purpose) and they need energy electrical or other energy systems that involve auxiliary installations with greater or lesser degree of complexity and maintenance.

The object of the invention of the autonomous irrigation system, formed by a conduit (2) - of adequate diameter to the flow rate - and a container (4) located inside the reservoir (1), is to allow the water to flow, without the need from another energy source other than the water entrance to the reservoir or reservoir (1). Therefore, its use is intended for hard-to-reach areas, where there are no energy sources and irrigation capacity is needed at intervals in a completely autonomous way.

Its great application is afforestation, where there are areas with small water uses (nascent) and only with the placement of a small reservoir to collect runoff (sometimes a few drops though constants) and the system described here achieves irrigation at preset intervals and quantities, throughout a geographical area of lower level to which the reservoir is placed.

The procedure is the next:

A water reservoir (1) of any capacity.

This is filled as a result of small existing runoff in the area, which results in an entry water constant (9) with irregular amounts, depending Even the time of day.

A bell-shaped duct (2) is placed Gauss inside, so that one end (2a) is the reservoir water outlet - in connection with irrigation pipes later- and the other end (2b) is free in the water.

To this last one some sieve or Pre-filter (3) to avoid clogging problems.

In the highest part of the bell is sandwiched a receptacle (4) as a buoy such that it is capable of house water inside, that is to say open on your part higher.

In this receptacle a small tube is immersed (4a) in the shape of Gauss's bell, with one end in the inside and the other in the air. The weight of the container must be enough to favor the sudden collapse of it, in the moment of activation of the irrigation.

The container and its components have joined by means of a rope (6) both at the bottom and at the deck in the case of closed reservoirs. If it is open reservoirs, enable a stem or similar to be able to fix higher.

The function of this axis of activation is that of make the movement stop (7A, 7B) and be able to ensure total verticality of the receptacle, since otherwise the balance dynamic forces would behave improperly.

The reservoir (1) slowly fills when the water level reaches the base of the receptacle (4), this at be empty, experience a flotation up to a stop (7A) that It will be marked by the length of the lower clamping rope (6i).

Water continues to rise along the length of the container (4), which is submerging slowly and when the water exceeds the level of the container (4), the entry occurs of water to it and a sudden subsidence of the submerging vessel completely the bell, allowing water to escape from deposit with hardly any resistance. The sudden collapse is produces up to a stop (7B) that is defined by the length of the upper clamping rope (6s)

As a result of this movement, the reservoir (1) it allows the water height between the point to exit highest in the receptacle (7A) - before sinking - to the end water level (2b). This way we can program the irrigation depending on this distance and the input flow to the reservoir.

The tube (4A) that pierces the container (4), has the same drain function as the duct (2), but its purpose is to bring the system to "rest" (empty container) to Be able to repeat the process.

To avoid unwanted resistance at the exit from the reservoir (outside the reservoir and in connection with the irrigation) install an air purge valve (8) in diameter equal to that of exit.

Once the water is evacuated it begins to fill the tank (1) again and the bell rises again a little little bit.

Dimensions (bell diameter, height, dimensions and weight of the receptacle) will be appropriate depending on of the volume of water to be used and the time between irrigation.

The pressure and flow variables are regulated downstream with commercial dropper devices self-compensating, sprinklers etc. or even with the right choice of a plantation level.

Claims (1)

1. Autonomous irrigation system that allows water supply at intervals and pre-set quantities, without need for another energy source than the water entrance itself to the deposit. It is based on a quantity of water that constantly enters a reservoir (1) in which the autonomous irrigation system is installed, characterized by a Gauss bell-shaped duct (2) inside, so that one end ( 2a) is the water outlet to the reservoir - in connection with the rear irrigation pipes - and the other end (2b), is free in the water and incorporates a sieve or filter (3) to avoid clogging problems. In the highest part of the bell formed by the duct (2), a vessel (4) is inserted as a buoy, which it incorporates another conduit (4a) in the form of a bell of Gauss, with the same drain functions as the duct (2), the end being which pierces the container at its base, which allows the exit of the water, and the other end is inside the container (4). The system is fixed by rope or similar to the deposit. The length of the lower restraint rope (6i) mark the buoyancy stop (7A) of the container (4), while the length of the upper restraint rope (6s) marks the top of sinking (7B) of the container (4).
