Description

Intercuencas transfer provision underwater

Object of the invention

The invention relates, as expressed by the set forth herein, at the disposal of intercuencas submarine transfer that contributes to the function to which allocates a number of advantages and features, in addition to the inherent in its organization and constitution, which will be described in detail later, and that suppose an innovative improvement to what already known in this field.

More specifically, the object of the invention consists of an arrangement that allows to take advantage of surplus flows from the surplus watersheds, for transfer them to basins and coastal areas deficit through an underwater pipeline that interconnects them taking advantage of the principle of communicating vessels to be the mouths from the rivers to the same level (sea level).

Field of the Invention

The field of application of the present invention it is the infrastructure building and more specifically the of the construction and realization of transfers between basins Hydrographic

Background of the invention

The classic intercuencas transfers have been been carrying out the construction of transport channels on land, whose water flows are achieved by slopes generated by losses of geometric dimensions or by drives through forced pipes, crossing lands that  they must be expropriated and carrying out clearing and other works of great ecological impact.

This type of construction implies that the flows of water are always unidirectional, in the sense of loss of dimension. As with the transfer Tajo-Segura of all known.

The creation of alternative systems that, for the purpose here concerned, solve the problem indicated, such as the provision of Intercuencas submarine transfer that advocates this invention, the petitioner of which he declares, that on the other hand, ignores the existence of any other that presents some similar technical, structural and constitutive characteristics and whose purpose is precisely to solve the inconveniences previously described presenting known systems currently.

Explanation of the invention.

Thus, the intercuencas transfer provision that the invention proposes, constitutes by itself an obvious new within its field of application, since according to its application is achieved in a taxable way a means that allows said transfer, not unidirectionally, but in any way, without requiring the expropriation of land from anyone and avoiding also any environmental impact on the landscape, since manages to collect the flow rates in one or several underwater pipelines leftover river basins just before being dumped at sea, taking advantage of the circumstances that all of them They lead to the same level.

Specifically, the system consists of taking the surplus waters of each basin by means of azudes, located at a dimension (preferably + 10 m) above sea level, and join them through 8 meter diameter pipes taking advantage of the principle of the communicating vessels.

Said pipe or pipes run advantageously submerged under the sea and near the coast, deriving from it radial sockets that supply some arches, conveniently distributed along the coast and located in dry land at the same height as the aforementioned azudes (+10 m), from which, by means of suction motor pumps, the flows to demand points.

Water flow is created by unevenness hydraulics when the water is sucked by the described ones motor pumps provided in the intake boxes.

It should be noted that when water flows are important, it is necessary to accelerate the water to compensate for transport load losses, by pumping towers arranged as a rosary along the pipe principal.

These pumping towers have a partition central where two groups of motor pumps placed one are placed versus another axial flow, which can accelerate at will the water flow in any direction, thus allowing match the direction of the demand.

These axial flow motor pumps work at variable speed creating a maximum slope of 6 m a.c. so that the pipes always work with pressure difference positive (higher inside than outside) avoiding collapse problems as well as pollution problems by seawater intrusion, since if a leak occurs, it will go from the inside out, to have more pressure inside, when taking the shots in blue at +10 m above the level of the sea.

These pumping towers, on the other hand, they have in their aerial part a helipad that allows advantageously air access to them.

In times of low demand, the invention provides water storage in overexploited coastal aquifers by artificial recharge through wells.

The main pipe is made with stainless material by helical welding procedure continue on ship, adapted for this purpose, placing in the seabed on the mark, from the material coil stainless (preferably AIS316L or higher), depending on the distance from the coast to be installed, from the marine profile particular of each zone, guaranteeing at all times a depth that allows the transit of ships of greater draft.

The new intercuencas transfer provision submarine therefore represents an innovative structure of structural and constitutive characteristics unknown until now for that purpose, reasons that together with its practical utility, the provide sufficient grounds to obtain the privilege of exclusivity requested.

Description of the drawings

To fill in the description that is being performing and in order to help a better understanding of the characteristics of the invention, is attached herein descriptive, as an integral part of it, of a game of planes, in which with an illustrative and non-limiting nature, represented the following:

Thus, as seen in the aforementioned figures and according to the numbering adopted in them, the provision of transfer in question, which as mentioned is based on the principle of communicating vessels, is essentially constituted from at least one main pipe (1), which will be performed by helical welding procedure continuous and whose diameter will be 8 meters, given the flow that can get to contain, to which the remaining flows of the Watersheds that interest, by means of azudes to take surplus water from the basin (2) located before its mouths (preferably at a level of 10 m above sea level), said main pipe (1) running, as seen in the Figure 1, submerged in the seabed parallel to the coast, and of the that flow from radial pipes (3) that feed the vaults of takes level (4) located on the firm ground and at the same level as the aforementioned azudes (2), logically located in the zones of the coastline more likely to require water contributions.

Spread every 70 km as a rosary, there are on the main pipe (1) a series of towers of pumping (5), which as shown in figure 2, have in its aerial part of the necessary services for its access and use by maintenance personnel, such as a helipad (6), navigation lighthouse (7), zone offices and homes (8), machine room (9), warehouse fuel (10), and suction and exhaust ports (11), which crown the hydraulic or submerged part of the tower (5), which serves as interconnection of the main pipe (1), by corresponding expansion joints (12), this being also main pipe (1), provided with corresponding boxes of inspection (13).

For its part, the submerged area is constituted by a structure or housing (14), and has a intermediate partition (15) in which motor pumps are housed (16) flow accelerators, which are responsible for causing the hydraulic slope that will produce the flow.

Said motor pumps (16) are found arranged in two groups facing each other, which they push one to the right and another to the left, being of a system by communicating vessels, thus allowing select the flow in the direction of interest with respect to the contribution point, which may vary depending on the availability of leftover flows.

On the other hand, Figure 3 shows how the various radial pipes (3) grafted into the pipe main (1), feed fresh water to the intake boxes (4), on which a suction pump is installed (17) responsible for pumping the flow to the different points of demand.

Describe sufficiently the nature of the invention, as well as how to put it into practice, is not considers it necessary to broaden his explanation so that any subject matter expert understands its scope and advantages that derive from it, stating that, within its essentiality, may be implemented in other forms of embodiment that differ in detail from that indicated by way of example, and which will also achieve the protection that collects as long as it does not alter, change or modify its principle fundamental.
