Description

Hydroelectric generation plant.

Object of the invention

The present invention relates, as expresses the statement of the present specification, to a industrial plant or facility specially designed for electric power generation by harnessing water resources of any kind, characterized by self-supply of said water and return it to the pond, lagoon, river, stream, sea, or similar water resource, from which it takes and in which it has been installed.

Field of the Invention

This invention has its application within the electric power generation industry aimed at all Possible uses

Background of the invention

The growing need for electric power production both from the relentless expansion experiencing the industrialized world and the increase every day of its demand, as for the most remote regions of the planet in which for obvious reasons the infrastructures are completely insufficient

The problems are also known derived from the scarcity of resources to obtain it, and the pollution problems and environmental deterioration caused by obtaining it uncontrollably.

Among the different methods of obtaining electrical energy, which is obtained through resources water, mostly produced by hydraulic plants, which, as is known, need the existence of courses of sufficient flow and of waterfalls and therefore of reservoirs to Move the turbines using their energy.

The primary objective of the present invention it consists precisely in obtaining hydroelectric power without the need to take advantage of leaps or strong currents of water, obtaining it in any place where it can be stored water or where a water resource of any kind.

It should be noted that the petitioner is unaware of the existence of a hydroelectric power plant that presents technical, structural and constitutive characteristics similar to those advocated by the present invention.

Explanation of the invention.

Thus, as mentioned previously, with the present invention a installation that applied to an electricity generator, it self-supply and return the water to the pond, lagoon, river, stream, sea, or similar water resource (hereinafter only pond for abbreviate) in which it is installed, so that such water is not Loses in the process.

In particular, the invention comprises following elements:

A main conduit or primary pipe, with the appropriate diameter and length dimensions and calculated for the projected load to be generated is placed vertically incorporating at its lower end located below the water level a check valve, and whose upper end is connected to another descending conduction or secondary pipe through a tube folded or siphon.

Said secondary pipe, found connected as mentioned to the lower end of the siphon, it will have a diameter at least 50% larger than that of the primary pipe, and a length at least six times longer. These dimensions may be increased in order to create a greater potential difference able to increase the suction on the primary pipe and therefore of the water flow of the project to be generated.

The lower end of the above pipe secondary, meanwhile, will connect with the turbine, reducing here its diameter of entrance to the measure of the diameter that has the primary spout

The turbine, meanwhile, will be provided with a drain, through which water is returned to the pond from which the socket, incorporating a valve or gate that will allow its closure to prime the system.

This operation is carried out before commissioning the installation with the help of a pump aspirant / impeller connected to the primary pipe.

Both the turbine and the electric generator connected to it will obviously be suitable for calculating determined flow for each specific load project, being also equipped with the corresponding regulatory equipment for frequency maintenance.

Finally, from the highest part of the siphon that splices the primary pipe with the secondary one, descends a drain pipe at the end of which, at an accessible height for a operator, incorporates a stopcock or valve, which, will remain open during the priming operation by ejecting the air and being closed when you start to expel water, which will be indicative of the operability of the system, given then opening to the turbine drain gate, causing water circulation and therefore operating the equipment generator.

For projects where the distance between the water intake through the primary pipe to the turbine, located in the end of the secondary spout, be long, as in the case of installations carried out on the coast of lagoons, tajamares, or on coasts of a conventional dam, etc., the invention it allows the projects of greater loads, however, for projects located in spaces whose size is smaller, such as short ponds, etc., where you cannot increase the water flow through spout lengthening calculations secondary for the maintenance of suction and constant flow, the invention provides an alternative embodiment in which the spout primary, after connection to the siphon, is coupled to a tank or intermediate deposit and this to the secondary pipe.

The alternative installation of said deposit, whose capacity must be at least three times greater than the sum of the capacity of the primary pipe and the siphon, will allow the secondary spout length can only be three times longer at the height of the primary pipe, thus reducing the dimensions of the set.

It should be noted that the pipe system of the installation will be supported by the appropriate structure, preferably consisting of iron or steel towers, capable of resist the weight of the pipes plus the water contained by them, being also sufficiently resistant to vibration produced by the circulation of water.

Moreover, optionally, depending on the orography of the land and the place of installation is expected realization of channels on the shore for both water intake by part of the primary pipe as for the discharge discharge of the turbine.

It is therefore manifest the innovative utility of the hydroelectric power plant advocated by the invention, which allows obtaining electrical energy in anywhere, with the sole condition of having a pond of water, which, once full, since it can also be treated as an artificial pond, you will not have to replace more than what you can lost by evaporation, for which a pond can be provided assistant.

On the other hand, given that the fuel that used for its operation is water, it will only cause expenses of maintenance of the equipment, being totally harmless to the environment, since it does not produce combustion gases as it happens with other types of plants such as thermal or diesel, being absolutely impossible any kind of accidental contamination by oil spills, hydrocarbons, etc.

Due to its characteristics, the installation, neither does it modify the chemical or physical conditions of the water, but which, on the contrary, enriches it in oxygen through its continuous circulation, thereby favoring the biological conditions for life in the ecosystem in which it is functioning.

The new hydroelectric power plant represents, therefore, an innovative structure of structural and constitutive characteristics unknown up to now for that purpose, reasons that together with its practical utility, the provide sufficient grounds to obtain the privilege of exclusivity requested.
