ECOLOGICAL MICRO-HYDROELECTRIC POWER PLANT WITHOUT WATER FALL FOR THE PLAIN AREAS OF RIVERS

摘要

The invention relates to an ecological micro-hydroelectric power plant without water fall for the plain areas of rivers which uses the energy of water and natural and artificial water vortices, in order to increase the efficiency thereof in relation to the extant micro-hydroelectric power plants. According to the invention, the micro-hydroelectric power plant comprises a support (17) equipped with two hydro turbines (9), a weir (4) for starting and stopping the hydro turbines (9) and for regulating the speed of some generators (10), a guard fence (19) for service operations, a confuser (2, 3) for protecting the hydro turbines (9) or for protecting and increasing the speed of the water flow, some floats (20), some guidings (21) for fixing the support (17) in the river bed, and also some generators (10), the hydro turbines (9) having two shafts (17) each, with some blades (5) arranged in two rows at 45°, the blades of the first row being arranged at 90° in relation to the blades of the other row, allowing the water (1) to flow as naturally as possible and taking over, at the same time, the mechanical energy of the water, and the blades (5) of the hydro turbines (9) are fixed only by some transmission chains (6), using the force of the water flow (1), the stoppers (11) and the guide rollers (13) both for locking the blades in the 45° position and for rotating the same, the two shafts (7) of the hydro turbines (9) being independent and thereby allowing the chains (6) to be mounted and tightened by means of left-hand and right-hand bolts (23), respectively.
