The invention refers to a spiral facility which, by rotating movements, takes over and transports liquids and mixtures of liquids and solids in an inclined plane, storing them until their distribution to beneficiaries; it is usable in both small households and for irrigation facilities or other industrial equipment.

Worldwide, there are different spiral conveyors that transport water on an inclined plane, that consist of a vat, a trough or a cylinder in which a worm screw, with or without an axle, takes over the water and transports it on an inclined plane; such devices are used to satisfy communitary needs or in agriculture, case in which they are manipulated with the help of conventional, traditional energies.

The most relevant solution in the state of art is represented by patent R0100563, in which the spiral conveyor is made of a cylinder inside which , fixed by means of continuous weld, there is a worm screw or a spiral, without an axle or a central shaft; the inferior end of the cylinder being supported on the foundation of a basin by an axial end bearing, and on the outside being supported on rollers, or axial-radial roller bearings; at the superior end, it is connected, by means of a coupling, to a direct drive or a geared motor which engages it in the rotational motion.

Another relevant document in the state of art, identified in the research process is patent FR2253690 which describes a spiral conveyor engaged by an electric motor.

The disadvantages of the known solutions are as follows: they have a limited transport length, a limited utility height and a slow functioning; the maintenance of these facilities is costly and, more than that, they cannot fully utilise the available water area. Another disadvantage is the fact that these solutions use conventional energy, which is not ecological, and the prices are too high for the water consumers. On top of that, all known solutions can only take over and transport water.

The technical problem that the invention is meant to solve is to manage the absorption and transport of water from flowing and standing water bodies, surface and ground water at long distance, and to provide water storage in reservoirs, canals, basins, water towers, etc., and to manage its distribution to beneficiaries without using conventional energy, therefore with smaller exploitation costs, by means of ecological, reliable sources such as the power of surface waters, wind or solar power.

The spiral facility, according to the invention, annihilates the disadvantages of prior solutions and solves the technical problem because it is made of a spiral conveyor, equipped with a shaft, with or without an axle, tightly fixed by an inside cylinder and supported, at the lower end by a bearing on the concreted bottom of a surface flowing water. On the outside the cylinder rests, from place to place on rollers, or on axial-radial roller bearings that are fixed in the supports. By engaging in the rotational motion, the water is assimilated from the source at the lower end, it is transported on the inclined plane and stored in a reservoir, canal, basin, water tower or other recipient for the storage and distribution of water placed at the superior end of the facility, until it is distributed, according to needs.

The spiral facility, according to the invention, has the following advantages:

- as it uses the regenerating water, wind or solar power, which is inexhaustible and free, the facility is not costly and it does not pollute, i.e. it is ecological.

- the facility can use, in theory, any volume of water, at any distance and at any high, depending on the dimensions and characteristics of the water source or wind.

- being technically uncomplicated and easy to use, it does not involve significant assembling investments , which is beneficial for water regulation and flood protection.

- being a simple and light device, the facility implies low maintenance costs and it can be adapted for transportation on wheels to the needed place and it can also be adapted as a floating device for water sources.

- when not used, the facility can be stored and, when needed, it can be transported, for instance, for periodical irrigations or in periods of drought in any area where water or wind is available.

- the maintenance costs are lower than the ones for any other facility that is used for periodical irrigations as well as in cases of drought, or for any other purpose.

- the water that gets to the consumers through this facility is much cheaper because of the low maintenance costs and the competitively of the work of the water beneficiaries is higher.

- the electric power that is produced can be directly used by the beneficiaries or it can be stored in batteries, together with the solar power, to repump the water from the reservoirs, basins or water towers to the higher levels of watering (irrigation).

Further on, we give an example of a practical application of the spiral facility, according to the invention, related to Figure 1, 2 and 3, which represent: - Fig. 1 : Section of the spiral facility with a vertical hydraulic wheel in the same body;

- Fig. 2: Section of the spiral facility moved by an independent vertical hydraulic wheel;

- Fig. 3: Section of the spiral facility moved by wind turbine;

The spiral facility (Figure 1) consists of a spiral conveyor 1, equipped with a hydraulic wheel 2, provided with blades, which is supported at the lower end by an end bearing 3, fixed in a concrete support 4, this being fixed, in its turn, on a concreted riverbed 5 and, on the outside the cylinder rests, form place to place, on rollers, or on axial-radial roller bearings 6 that are fixed in the supports 7.

The hydraulic wheel 2 has the function to absorb the regenerating water power to the purpose of rotating the spiral conveyor 1; this will take the water from the river by a winding movement, transporting it on an inclined plane to the reservoir 8, where it is stored, and from where it is further transported to the beneficiaries, by free fall.

On the outside, the cylinder of the spiral conveyor 1 has an electric generator 9 that is powered by the rotational motion of the spiral conveyor 1.

In another version of practical application, the spiral facility (Figure 2) consists of a spiral conveyor 1 supported, at the lower end, by a bearing 3, fixed on a concrete support 4 directly on the riverbed 5 of a surface flowing water body.

On the outside, the spiral conveyor 1 rests, from place to place, on rollers, or on axial- radial roller bearings 6 that are fixed in the supports 7. On the outside, on the cylinder, the spiral conveyor 1 has a mechanism 10 connected through an axle 11 to a hydraulic wheel 2 with blades, fixed in some concrete supports that are either all in the river, or on either sides of the river. The blades of the hydraulic wheel 2 are moved by the flowing water that rotates due to the mechanism of the spiral conveyor 1 which takes the water from the river at its lower end, transports it on an inclined plane and stores it in a reservoir 8 at its superior extremity. The cylinder of the spiral conveyor 1 is also provided with an electric generator 9 that is started by the rotational motion of the spiral conveyor.

In a third example of a practical application, the spiral facility (Figure 3), consists of a spiral conveyor 1 supported at the lower end by a bearing 3, on the concreted riverbed 5 of a ground flowing water, or in the concreted riverbed 5 of a flowing water with a high flow and low velocity or at the bottom 5 of a lake, sea or ocean. On the outside, the spiral conveyor 1 rests, from place to place, from place to place, on rollers, or on axial-radial roller bearings 6 that are fixed in some supports 7 and 4. On the outside, on its cylinder, the spiral conveyor 1 has a mechanism 10 connected to a wind turbine 12 that may or may not produce electric power, which, by a rotating motion, also starts the spiral conveyor 1 that absorbs, at its lower end, the water from the river, sea or ocean, which it transports, on an inclined plane, and stores in a reservoir 8 placed at its superior end. The cylinder of the spiral conveyor 1 is also provided with an electric generator 9 that is started by the rotational motion of the spiral conveyor 1.
