Description

Telecontrolled irrigation hydrant.

Object of the invention

The present invention relates to a hydrant Telecontrol of those used in irrigation systems.

The object of the invention is to provide a device that besides allowing to control the opening and closing of water connections in remote irrigators, have the power to record and control the flow of water that circulates through these sockets, without the need to install expensive meters, and all It automatically.

Background of the invention

In modern irrigation the need is imposed to control the water intakes of each irrigator, the flows provided and the opening and closing moments of the water intakes from offices, usually all under the control of the Administration.

For this it is necessary that the opening and closing of the sockets or valves that provide irrigation to each zone is made of remotely using radio or telephone systems.

Due to the shortage of irrigation water is done it is necessary that the billing is carried out according to the flows used, (much more precise system) instead of depending on the opening time of each shot.

The installation of individual counters assumes additional problems regarding impurities in irrigation water, resulting in an excessively expensive practice.

Also, when water is provided by ditches and not by piped and pressurized lines, the installation of Physical counters is unfeasible.

The applicant himself owns the patent of invention P9900911 in which an irrigation method is described automated with prior authorization, based on a system of remote management of hydrants or gates controlled by an Agency that authorizes openings.

However, these types of systems are based on valves that open or close completely at the time of irrigation, together with meters responsible for reading the flow contributed to invoice, presenting problems such as breakdowns that may occur in the counters due to impurities present in irrigated water, the high cost of installation or the inability to change from the remote center the hydrant flow rate, since the sockets open or close completely, providing preset flows through adjustments manuals on the valve.

When opening or closing the valve or gate completely, the limitation of irrigation at that flow rate can only be carry out by controlling the irrigation time, which means limit the possibilities of use of the farmer or user.

Description of the invention

The hydrant for telecontrolled irrigation that the proposed invention resolves in a fully satisfactory manner the problematic previously exposed in the different aspects commented, allowing the regulation of flows as well as the registration of such flows, being able to be implemented both in irrigation systems fed through piped lines and pressurized as through channels or ditches, without the need for having to install expensive water meters.

For this, the hydrant consists of a valve or motorized drive gate through which it is connected to the irrigation system, so that if irrigation water is contributed to through channels it will incorporate a gate, and if it's pipes a valve, in any case both motorized, the which are associated to a control circuit or system and remote management that allows its controlled opening both locally as at a distance, said valve or parameterized gate of  way that the opening control circuit of it based on that parameterization automatically calculates the step surface of water depending on the degree of opening of it.

According to another of the characteristics of the invention, the hydrant incorporates a measurement system of the pressure at the entrance and exit thereof, so that set the pressure difference, the control circuit allows to calculate through this information and the surface of water flow, automatically the irrigation flow that passes to through the hydrant.

In the case of irrigation through piped lines the pressure measurement system will materialize in two pressure sensors at the inlet and outlet of the hydrant, while if the irrigation is channeled said system will it will materialize in two water level sensors, obtaining the difference of pressures for difference of heights at the entrance and Hydrant outlet.

As is evident, the control circuit of the hydrant will be assisted by the corresponding battery of feeding.

Thus, through the structuring described, allows to count individual consumptions without installing physical counters, which means strict irrigation control in large areas, by remote management, avoiding breakdowns in counters and to costs assumed by the bodies responsible for the supply.

A compact device is thus obtained by being the different elements that form it related to each other.

For optimal operation of the device is it is necessary that the water flow regime where the average is carried out of pressure is laminar, so the distance to the Last element that can create turbulence. In this sense it is important that the regulating valve creates the minimum of turbulence so that the parameterization of the elements that they intervene and the distance between them is correct.

The control circuit is programmed to In addition to counting consumption, provide different flows through remote control in the way you want, that is to say through flow constant, constant pressure at the inlet or constant pressure at the exit.

Finally, it should be noted that the device can incorporate a pre-authorized solenoid valve, which It is also assisted by the control circuit, but whose opening will only be possible by prior authorization of the Control body, so that the virtual counter is only will start when the irrigator requests the irrigation and the center of control authorize it.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a single plan where illustrative and non-limiting nature, a view has been represented in perspective of a telecontrolled irrigation hydrant made of according to the object of the invention.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as in the hydrant that is recommended participates a motorized actuation valve (1) through which communicates with the irrigation system (2), which in the example of practical embodiment shown in the figures is a line piped and pressurized, but that could also be a irrigation system by channels, in which case said valve is would materialize in a drive gate likewise motorized, drive that is governed by a circuit or control and remote management system (3), which incorporates means for its remote control via radio or telephone systems, said circuit (3) can also be operated locally, by means of a control panel (4), being fed through the corresponding electric battery (5).

Well, the opening of the valve (1) or in its case of the gate, it is previously parameterized and preprogrammed in said circuit or control and remote management system (3), of so that it can calculate and control at all times the surface or section of water passage through the valve (1) in function of the degree of opening of the same.

The structure described above is complements with a system for measuring the difference of pressures also associated with said control circuit (3), of so that said circuit calculates through the information parameterized and associated with the degree of opening of the valve (1) and of the pressure difference at the inlet (2) and at the outlet (6) of the system the flow of water through the hydrant, said system of measuring the difference of pressures in the case of a piped and pressurized irrigation line in a pressure sensor (7) upstream and a pressure sensor (8) located downstream.

If irrigation is channeled, said system will it will materialize in two water level sensors, obtaining the difference of pressures for difference of heights at the entrance and Hydrant outlet.

The control circuit (3) may provide different flows by remote control in the mode that want, both by constant flow, constant pressure to the constant inlet or pressure at the outlet.

The structure described above may optionally incorporate a pre-authorized solenoid valve (9), assisted by the control circuit (3), but whose order of opening may only be issued by the Control Body, of so that the virtual counter will only be launched when the watering request the irrigation and the control center authorizes it.
