    [0001]
    [0002] Hydroelectric power station.
    [0003]
    [0004] TECHNICAL SECTOR
    [0005]
    [0006] The present invention refers to a hydroelectric power station, whose obvious purpose is to transform the kinetic energy of water into electrical energy, all with a closed circuit.
    [0007]
    [0008] The invention is therefore located in the field of renewable and clean energies, without the generation of pollutants during the entire transformation process, and not requiring any type of fuel and allowing the generation of electrical energy 24 hours a day.
    [0009]
    [0010] The object of the invention is to provide an electrical energy generation installation with minimal costs in said energy generation once the installation is obtained, which is not affected by adverse weather conditions.
    [0011]
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] In the field of practical application of the invention, that of clean and renewable energies, there is a common denominator for this type of energy, and that is the problem of dependence on weather conditions for its operation, so that these systems can stop working due to lack of wind (wind turbines), sunlight (photovoltaic installations), or insufficient water collected in reservoirs (hydroelectric plants).
    [0015]
    [0016] EXPLANATION OF THE INVENTION
    [0017]
    [0018] The hydroelectric power plant that is being advocated solves the aforementioned problem in a fully satisfactory way, being totally independent of the existing weather conditions, being able to generate energy 24 hours a day, 365 days a year. year.
    [0019]
    [0020] For this, and more specifically, the plant of the invention is constituted from one or more modules, constituted from a vertical structure of considerable height, at whose upper end a cargo tank is established through which feeds a spiral line that runs vertically through the structure to a turbine area where the line is topped by a series of nozzles that eject pressurized water onto the propeller blades of a turbine whose shaft drives a generator electric.
    [0021]
    [0022] Under this set, a discharge tank is established, to which a pumping equipment is connected that lifts the water to the loading tank.
    [0023]
    [0024] For this function, it has been planned that the pumping equipment be divided into two parallel installations, one, which will pump 70% of the flow, will be implemented from hydraulic ram pumps, while the second installation, which will redirect 30% of the flow, it will do it through one or more electric pumps.
    [0025]
    [0026] In this way, a balance of the descending and ascending water volume is achieved in order that the installation can operate continuously, without stops.
    [0027]
    [0028] In accordance with another of the characteristics of the invention, the discharge tank will be arranged at a certain height from the ground or zero level, at least three meters high, establishing under it a cabin for pumping systems, which will be located by below the ground level, the ram pumps at a depth of at least 6 meters with respect to the bottom of the discharge tank, while the electric pump or pumps will be arranged at a greater depth, in order that there is a gap between this group of bombs and ram pumps.
    [0029]
    [0030] In this way, an installation is achieved that allows the kinetic energy of the water flow circulating through the vertical helical pipe to be transformed into electrical energy, in a closed circuit, in which there are hardly any losses.
    [0031] DESCRIPTION OF THE DRAWINGS
    [0032]
    [0033] To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical embodiment thereof, a set of drawings is included as an integral part of said description. where, by way of illustration and not limitation, the following has been represented:
    [0034]
    [0035] Figure 1.- Shows a schematic perspective view of a hydroelectric power station made in accordance with the object of the present invention.
    [0036]
    [0037] Figure 2.- Shows an enlarged detail of the installation at the level of the pressurized water impeller nozzles on the corresponding propeller of the electric power generating turbine.
    [0038]
    [0039] PREFERRED EMBODIMENT OF THE INVENTION
    [0040]
    [0041] In view of the figures outlined, it can be seen how the power station of the invention is constituted from at least one module in which a vertical structure (12) of reinforced concrete and steel participates, in whose upper area a tank of load (1), which will be filled with 45 m to 55 m of clean water, a tank that will be covered on the top to prevent dirt from entering it.
    [0042]
    [0043] The tank discharges inferiorly through a main stopcock (13) and regulator of the water flow, through which the circulation of water and the greater or lesser flow to a spiral downpipe (11) can be controlled. of water, made of non-oxidizing material, such as stainless steel, PVC or others. The pipe will be anchored and fixed in the interior pavements of each of the floors of the vertical structure (12), redirecting the water from the cargo tank (1) to the turbine area, so that the spiral configuration of this conduction makes the water circulate downwards for a longer time, achieving greater acceleration of the water and therefore more pressure and impact power of the water on the blades of the turbine propeller (5), achieving an efficiency of the order of three times greater compared to straight driving.
    [0044] As can be seen in greater detail in Figure 2, the spiral pipe (11) is internally finished off in an annular conduit in which a series of nozzles (14) of smaller diameter than the spiral pipe (11) are distributed, that direct the flow of water towards the blades of the turbine (5), reducing the flow of water, having a much smaller outlet diameter, thus increasing the outlet pressure, being able to install 4, 6 or as many nozzles as necessary, depending on the type of turbine (5).
    [0045]
    [0046] As for the turbine (5), a hydraulic turbine with technical characteristics will be installed, which are the most appropriate, with respect to the pressure and flow rate of the water that impacts its blades or propellers.
    [0047]
    [0048] The turbine shaft (5) will be connected to a mechanical generator (6), and may include a speed multiplier.
    [0049]
    [0050] Under the turbine (5) a discharge tank (2) is established, on which the turbinated water is stored.
    [0051]
    [0052] Initially, the loading tank (1) is completely filled with water, while the discharge tank (2) is filled to a third of its capacity, so that once the loading tank (1) is filled, the cut (8) and water flow regulator, lowering it through the spiral pipe (13), leaving the liquid through the nozzles (14) and impacting the blades or propellers of the turbine (5), which will drive the mechanical generator (6) thus generating electrical energy.
    [0053]
    [0054] Returning again to figure 1, the discharge tank (2) will be associated with a group (3) of hydraulic ram pumps (9), which, being hydraulic, do not consume electrical energy, so it is necessary to calculate the water flow that descends through the spiral pipe (13) to balance the recirculation of the turbined water towards the load tank (1), recirculation which, as mentioned, will be done through the aforementioned group of hydraulic ram pumps (3) as well as by means of one or more electric water pumps (4).
    [0055]
    [0056] More specifically, of the 100% of the water that reaches the hydraulic ram pumps (9), 70% is pumped through them, discharging 30% of said volume of water to a tank with an electric water pump (4), a pump in charge of recirculating that 30% of water flow to the loading tank (1).
    [0057]
    [0058] It is worth noting the fact that non-return water valves (7) will be installed in the vertical conduits to redirect the water flow to the load tank (1) in order that the water columns never back down.
    [0059]
    [0060] Individual cut-off valves (8) will also be installed for each hydraulic ram pump (9), being convenient to install a water filter in each ram pump for possible impurities, small solid bodies, etc.
