Definitions
- the present invention relates to the technological field of hydroelectric power plants, in other words power plants which exploit a difference in levels between the point at which the water is taken in and the point at which the potential energy of the water is converted, usually by means of turbines, into mechanical energy which moves one or more generators of electrical current.
- a power plant of this type comprises a dam which creates a reservoir into which flows the water of a river whose course is interrupted by the dam.
- the water reaches a specified level in the reservoir, and its potential energy is used at the base of the dam, by making the water pass out of the reservoir through penstock tubes.
- This type of hydroelectric power plant is, in the first place, very expensive because of the cost of constructing the dam, and furthermore it can only be built in mountainous districts or at least in a district having a sufficiently narrow valley to ensure that the water which fills the artificial reservoir created by a dam can accumulate to a specified level without occupying an excessively large surface area. This is one of the reasons why it is impossible to build hydroelectric power plants with sufficient power to meet local energy requirements in flat regions.
- hydroelectric reservoirs can be formed by means of dams, they spoil the appearance of the landscape and disrupt the ecological balance of the areas which they occupy.
- the inventor of the present invention has devised a new power plant, which is simple to construct, and which exploits the difference in levels between two points located along the bed of a river by positioning one or more penstock tubes which connect the aforesaid two points on the river bed, or immediately beneath it.
- Figures 1 and 2 show how a hydroelectric power plant 1 according to the invention comprises a penstock tube 3, installed on the bed 4 of a river 5 over a total length L, and provided with an intake aperture 3i located at the upstream end and an outlet aperture 3u located at the downstream end.
- the difference in levels between the centres A, B of these apertures 3i, 3u has a specific height H, and the water passing through the penstock tube 3 can transfer its corresponding potential energy to a mechanical device of a known type, located at the said outlet aperture 3u, which drives one or more generators of electrical current (a single generator, indicated by the number 2, in the present case).
- This generator which is integral with the mechanical device (not shown separately in the drawings), can be located, as shown in Figure 2, immediately above the bed of the river 5, still at the level of the said point B of the outlet aperture 3u.
- the inventor proposes the construction of a tank 7, with its base 7e positioned essentially at the same level as the said outlet aperture 3u, into which the excess water can be made to flow before it reaches the outlet aperture 3u, by means of a number of ducts 6 provided with shut-off valves 6t which are preferably remotely controlled.
- the said excess water, reaching a desired level K in the said tank 7 thus forms a reserve to be used for the said generator 2 or for another supplementary generator of electrical current at times of peak energy demand.
- hydroelectric power plant 1 which is versatile, and less expensive and more environmentally friendly than power plants which use reservoirs created by dams, is produced.
- the declared object of the inventor is achieved.
