For this, it includes means for the temporary storage of the water necessary for the production of hydroelectric energy, and means that, solely in function of the electrical needs, allow the conduction of this water to a generator. Means for activation are also provided of the means of conducting water, fed by an autonomous and ecological energy source.
    [0018] The object of the present invention is now to propose a solution aimed at improving the general efficiency of the installation described in document FR 2949516, fulfilling the technical, budgetary and environmental criteria currently in force.
    [0020] To this end, the present invention refers to a mini hydroelectric power station comprising a water collection tank and a water storage tank, the bottom of which is located in a horizontal plane lower than that in which the bottom of the water tank extends. water collection, said water collection and storage tanks are interconnected by a conduit, intended to allow the flow of the water contained in the water collection tank to the water storage tank, and in which a turbine is housed of an electricity generator, said mini-central also comprising a device to raise the water contained in the water storage tank to the water collection tank, said water lifting device comprises a wheel with an axis parallel to the bottoms of the tanks , in whose circumference a plurality of buckets are distributed, said bucket wheel being driven in rotation around of its shaft by an input wheel driven by a motor, and to which it is connected by a shaft passing through their respective centers, characterized in that the toothed wheel comprises a counterweight system, the total mass of which is equal to the mass of the whole formed by the sprocket wheel and the bucket wheel when carrying water.
    [0022] According to an advantageous embodiment of the invention, the counterweight system comprises a plurality of spokes that extend between the center of the sprocket and its circumference, each carrying at least one block of a material.
    [0024] In this case, the counterweight system may preferably include eight spokes each forming a 45 ° angle with an adjacent spoke, while the blocks of material are arranged at the wheel-connected end of their respective spokes and are shaped to match. with the inner circumference of the sprocket.
    [0026] The advantages resulting from the present invention will become apparent when reading the following description relating to an embodiment example illustrated in the attached drawings in which: [Fig.1] is a block diagram of the operation of a mini hydroelectric power station according to the invention, and
    [0028] [Fig.2] is a detailed view of an alternative embodiment of the water lifting device comprising the mini-plant according to the invention, seen from the observation direction A shown schematically in Figure 1.
    [0030] With reference to the figures, the present invention refers to a mini hydroelectric plant 100 comprising a water collection tank 1 and a water storage tank 3, the bottom 30 of which is located in a horizontal plane, lower than that in the extending the bottom 10 of the water collection tank 1.
    [0032] The two tanks 1, 3 are connected to each other by a conduit 2, designed to allow the passage of the water contained in the water collection tank 1 towards the water storage tank 3, and in which a turbine 4 of an electricity generator 5.
    [0034] The opening and closing of conduit 2 are controlled by a solenoid valve (not shown) that allows or interrupts the flow of water to turbine 4, and therefore to produce or not produce electricity in generator 5. This generator supplies, for example , a home network such as a single-family home.
    [0036] Furthermore, a device is provided to raise the water contained in the water storage tank 3 towards the water collection tank 1, which advantageously allows a closed-loop use of the water intended for the production of electricity by the mini power plant. 100.
    [0038] As illustrated in figure 2, this water lifting device comprises a wheel 6, with an X axis parallel to the bottoms 10, 30 of the tanks 1, 3, and on the circumference of which eight buckets 7 are distributed, by For example, cylindrical in shape. The latter are intended to extract water from the storage tank 3 and then empty it into the collection tank 1 during the rotational movement of the wheel 6. Therefore, the latter is partially submerged in the storage tank 3 and has a diameter d, adapted as a function of the distance separating the two water collection and storage tanks 1, 3, and which makes it possible to ensure that the water contained in the buckets 7 flow into the collection tank 1 when they reach the height of the inlet opening thereof.
    [0040] Conventionally, the bucket wheel 6 is driven in rotation around its axis X by a toothed wheel 8 of diameter D greater than d, and to which it is connected by an axis 11 through their respective centers 12, 13.
