Definitions

  • the present invention relates to the generation of electrical energy in hydroelectric plants. More particularly, it refers to improvements in the collection of endorheic currents to take advantage of them in the generation of electrical energy.
  • the concept on which the improvement provided by this application is based is that of not waiting until the endorheic waters reach their lowest level, forming river currents that already leave the basin, and then build, on the adequate sites, dams that allow the use of these waters for various purposes, such as irrigation and electricity generation.
  • the present application proposes to form, in a given basin, a plurality of polygonal openings arranged to form transient reservoirs in continuous river current.
  • These polygonal openings would be arranged at convenient altitude levels, and would be located in what is known as a "cascade" arrangement, where the exit of a first polygonal opening formed at the highest altitude would serve to fill r a polygonal opening arranged at a second altitude, lower than the first and whose exit would serve to feed a third polygonal opening, formed at a third altitude, lower than the first two, and so on, until reaching the lowest level, in which the traditional dam would be found.
  • the improvement of the present also contemplates the formation of a series of perpendicular channels, diagonally inclined, arranged at convenient altitudes. These pipes would be arranged laterally below the polygonal openings and staggered on both sides of the pipes, in order to take advantage of several times the same volume of water, at different altitude levels, before it reaches the main dam or leaves. of the basin.
  • Figure 1 is a flow chart that illustrates the way in which the same volume of water can be used several times for the generation of electrical energy.
  • the improvements made by the present application can be considered directed to the use of the same volume of water for the generation of electricity, in generators operated by your rains moved by said volume of water; said generators being arranged at different levels of altitude, so that the water leaving a first turbine located at a first altitude level, come to move a second turbine located at a second altitude level lower than the first one and , in turn, that same water, when leaving the second turbine, can move a third turbine located at a third altitude elevation, lower than the first two, and so on, until it reaches the level where it is either a traditional dam, with its bank of electricity generators, or a simple river current that leaves the basin.
  • An additional step provided by the present application consists in capturing the water that left the first turbine, temporarily retaining it in order to again form a body of water sufficient for the second time to be used, and conduct it properly again until a new site, where it can be used to move a second turbine which, in turn, drives a second generator in a known way.
  • This arrangement would be located at an altitude level, lower than the first.
  • This additional step can be repeated several times, in similar arrangements, successively, at lower levels, so that a "cascade" system is formed, whereby the same volume of dammed water temporarily at the highest level, it is used repeatedly to generate electricity.
  • the advantage is obtained, on the one hand, of generating more electricity with less water; at a lower cost per kilowatt / hour and without the volume of water dammed in a normal dam, used for electricity generation, increasing with the consequent decrease in other uses of water, such as irrigation.
  • a river current leaving the basin there are naturally low levels, following the uneven terrain, to the lowest point, where various runoffs meet, which may have formed, incl., Streams, thus forming a A river current leaving the basin.
  • These spills become more abundant in the rainy season, where not only the humidity of the fog and low clouds is deposited on the rocks, trees and other surfaces, from where their runoff begins, but also rainwater that can form streams is added. These can reach very high speeds which can mean danger to the populations located in the low points, as often happens.
  • a collateral advantage of the improvements provided by the present is the network of the possibility of the formation of these streams, by capturing the runoff, of whatever type, and by fitting them properly for its use. This is achieved through the provision of a series of drainage collection arrangements, consisting of C 1 A, C2A pipes, arranged adequately to a first level, which will be called level A, and which will be the highest altitude.
  • each of the pipes is provided with a suitable pipeline 10, 11, respectively.
  • the C1A and C2A pipes will be extended to the extent necessary to capture most of the runoff.
  • the pipelines 10, 11 will have a sufficient inclination to drive the water to the first ETA temporary reservoir.
  • the first ETA temporary reservoir will be discharged through a second duct 12, which flows into the DA turbine, which will move the turbine and this, in turn, will drive the generator (not shown).
  • a second C1B channel located at a second altitude level (level B), lower than level A of the first channels, gathers, in addition to the runoff produced in the area, which could not be captured by channels C1A and C2A, the water stream from the first DA turbine, and leads them to the second ETB temporary reservoir.
  • the second ETB temporary reservoir has the same purpose as the first ETA temporary reservoir; but its situation is located at a lower level (level B).
  • the second ETB reservoir When the volume of water temporarily retained in the second ETB reservoir is sufficient to be used, it is allowed to leave the second ETB reservoir through the duct 13, which flows into a second DB turbine, to move it.
  • the DB turbine in turn, is connected to a generator (not shown) that generates electric current. It is appropriate to point out that the outputs of the electric current generators can be connected to each other selectively, so that a common output of the generator system is produced, which can be fed separately to service lines, or that can be added to the generator output or generators powered by water from a conventional dam.
  • turbogenerators is conceived, conceived as a unitary mixed element, or any other types of elements capable of transforming the mechanical energy of the water to electrical energy.
  • Said third stage would be fed from a third reservoir (not shown), in which the water coming from the second turbine would be accumulated plus the water of the deposits captured between level B and level C in the that said third stage would be located.
  • the accumulated water would be passed to a third turbine (not shown) that would move a third generator (not shown) to produce more electric current, with basically the same volume of water plus the spikes captured in each successive stage, which of otherwise they would be lost or go to the main EP reservoir.
  • the output of the DB turbine is passed r, through the pipeline 1 4, to the main reservoir EP.
  • pipeline 14 could selectively flow into a river current out of the basin, if there is no main reservoir.
  • the pipeline 14 in any of the two modalities mentioned above, may originate at the exit of a third, a fourth or nth tenth of your winding, instead of the second one your DB winding, which is Illustrated in the drawings.
  • the number of the Turbine at whose exit the pipeline 14 would originate, will depend on the orographic characteristics, the extension and the conditions of the hydrological basin in which the concept of the present application is put into practice.

Abstract

La présente invention concerne la formation d'une pluralité d'ouvertures polygonales conçues pour former des bassins de retenue transitoires dans un courant fluvial continu. Lesdites ouvertures polygonales sont disposées à des cotes d'altitude adéquates et sont localisées du fait qu'elles présentent une disposition "en cascade", où la sortie d'une première ouverture polygonale formée à l'altitude la plus élevée sert à remplir une ouverture polygonale située à une seconde altitude, plus basse que la première et dont la sortie sert à alimenter une troisième ouverture polygonale, formée à une troisième altitude, inférieure aux deux premières, et ainsi de suite, jusqu'à atteindre le niveau le plus bas. L'amélioration apportée par la présente invention concerne aussi la formation d'une série de canalisations perpendiculaires, inclinées en diagonal, disposées à des altitudes adéquates. Ces canalisations sont disposées latéralement en-dessous des ouvertures polygonales et en étages sur les deux côtés des canalisations, pour profiter plusieurs fois du même volume d'eau, à des cotes d'altitude distinctes, avant qu'il arrive à la retenue principale ou à la sortie du bassin.
