FR2462585A1 - Combined pump and turbine electrical generator - has closed loop of three vertically spaced reservoirs and vacuum pumps driven by pressurised water in upper reservoir - Google Patents

Abstract

The electrical energy generator is based on atmospheric and water pressure, and is esp. useful in areas remote from conventional installations. The system consists of a closed loop formed by a hydroelectric turbine (9) and vacuum pumps (4) between a group of three water reservoirs (1,7,5) arranged in three vertical steps the overall height being less than ten meters. Water from the base tank is drawn alternately to two small upper tanks (2) by the vacuum pumps and tank pressure via an automatic valve (3). The tanks are released alternately into the highest reservoir and then the second via and driving the vacuum pumps. The water finally flows to the lowest reservoir driving the turbine generator, the return path to the upper tanks being assisted by the air pressure built up within it.

Description

 The object is to produce constant hydroelectric power, by a simultaneous pumped storage system of the same volume of water distributed in three superimposed basins q. lower levels q. 10 meters between the level of the upper basin and the level of the lower basin.

The use of the gravitational force in the form of a waterfall for the production of hydroelectric power, does not exclude the possibility of using a second natural force such as atmospheric pressure, together with the first at l using an appropriate pumping system to create a continuous hydraulic circuit producing energy
The method used comprises according to ri. i, FIG.I, a production unit formed by three basins of identical content located at different levels, lower than IO metros between the upper basin and the lower basin The upper basin.T is surmounted by two watertight tanks, connected by a automatic operating valve, PL. II, Fig.2, connected itself to the pumping device, the latter according to PL.III, Fig. 3 and 4, is constituted by a bundle of air fluid powered air potatoes, using the water of the upper basin as pressurized fluid to drive in rotation a drum provided with fins rotating freely in a sealed chamber, to ensure th air soup in each of the tanks including alternative filling. is supplied by two separate pipes plunging through a foot valve into the lower basin 5, The separate emptying of each tank is carried out automatically using a known device of automatic tank 6. water from the hunts feeds the upper tank 1, which in turn feeds the intermediate tank 1, with water from the air pumps,
On the latter is engaged the force pipe 8 supplying the turbine 9, coupled to the current generator. the water from the turbine suffocates in free fall in the lower basin =,
T. 'it can be seen that the hydraulic circuit is thus made without the intervention without the intervention of an external motor element supplying the basins, thus ensuring the functioning of the turbine continuously.

 I1 goes without saying that the atmospheric pressure used as a driving organ for the ascent of the water, being essentially variable, the pumping system with multiple beams according to PL.IV, w; g.5 allows the regulation of supply of the basins whose the level must remain more or less constant by automatic intervention of the pumping beams as required.

 the adoption of a production system composed of several pumping units supplying, as required, a turbo group of determined power constitutes an economical solution, moreover allowing the construction of mass production units, their transport of elements and their assembly on the spot.

Your applications of this energy-producing device are
numerous, in particular in the electrical equipment of sites
or isolated agglomerations whose equipment by trans lines
port would be too expensive, due to losses by the Joule effect.
