PROCEDURE FOR ENERGY PRODUCTION IN POWER PLANTS INSTALLED IN A ROOM UNDER THE WATER SURFACE OF A HEAD STORE

Abstract: The invention concerns a procedure for pushing aside water and for energy production in connection with conventional power plants (4) erected in rooms beside head store (1) and under the water surface of head store. Water from the head store (1) is led in tunnel (3) to and through power plant (4) for gathering in a return store (5) dimensioned for more than normal operation, thus making it possible to operate power plant (4) also when arrangement for pushing aside water is shut off or has lower capacity than the feeder stream, and from there forward in tunnel (6) to store (7) located in direct connection to the head store (1). Pushing aside water from store (5) and to head store (1) will be done by arrangements and by auxiliary energy from wind, waves, tide-water, nuclear fuel, hydrogen, electric current and conventional explosive substance. The space in return store (4) which is not filled with water constitutes a form of energy storage, and auxiliary energy from the power sources mentioned above can effectively be utilized and plants located where there are favourable conditions for utilizing auxiliary energy for operation of arrangement for pushing aside water and where there is a market for produced energy.

Description: Procedure for energy production in power plants installed in a room under the water surface of a head store . The invention "SVEVOZ Power Plant" concerns a procedure for energy production in power plants installed in a room under the water surface of a head store. Energy production in conventional v/ater power plants demands running water from higher to lower level, and the running water quantity together with the difference of height decide at different periods the quantity of the produced energy. According to the known method the water is pumped back to a new level height when there is surplus energy and consequently no need to supply electric energy at that time. Energy production in water power plants in combination with the back pumping of water has not got any larger extent yet, due to the fact that, among other things, the energy available for the back pumping has been too expensive. Energy from wind, waves and tide-water is cheap and suitable energy for back pumping of water, but places where these kinds of energy are available and where power plants are placed seldom coincide. Energy production and energy storing according to the proceeding of the invention can be localized to places independent of supply of running water and differences in height for storing of back pumped water and where desirable supply and conditions exist to utilize wanted energy for operation of arrangement for the pushing aside of water and where there is a market for produced energy. The present invention comprises a system for energy production with effective arrangements for the pushing aside of water operated by energy from wind, waves, tide¬ water, nuclear fuel, hydrogen, electric current and conventional explosives. Within the frame of the system, conventional centrifugal pumps can, as an alternative, also be used. The effect of the energy storing in the return store, dimensioned for more than normal operation, constitutes a part component in the system, and arrangements in alterna¬ tive models, using varying kinds of energy for operation of these arrangements give the characteristics of the system stated in the claims where, among other things, the level height of the water also can be utilized without claims for running water or embankments, i.e. differences in level. The characteristics and details of the invention are clear from the following descrip¬ tion with reference to enclosed drawings, in which figure 1 is showing a plant for accomplish¬ ment of the proceeding in vertical plane at which pump piston operates by wind energy and/or by electric energy; figure 2 is showing a plant for accomplishment of the proceeding in vertical plane at which pump piston operates by wave energy and/or by electric energy, figure 3 is showing a plant for accomplishment of the proceeding in vertical plane at which pump piston operates by l id e-watcr, wind , waves and/or by electric eneigy; figure 4 is show ing a plant for accomplishment of the proceeding in vertical plane at w hich activated explosive lifts water in the store; figure 5 is showing a plant for accomplishment of the proceeding in vertical plane at which activated explosive presses water out of the store; figure 6 is showing a plant for accomplishment of the proceeding at which activated explo¬ sive lifts pump piston. According to figure 1 water is led from head store 1 in a tunnel 3 to and through a power plant 4 for gathering in a return store 5. .From the return store 5 water is led in a tunnel 6 to a secondary store7. Wind energy — earlier known method — generated by arrangement 13 lifts or wrings up a pump piston 8. Water from the store 7 will then fill up the released space. At return the pump piston 8 presses water from pit 9, situated under the pump piston 8 through back valves 10 and back to the head store 1. As an alternative, the pump piston 8 is screw formed for transport of water from the store 7 and back to hea store 1. In pump house 14 there is equipment for an alternative operation of pump piston 8 with or without a combination with wind energy. According to figure 2 water is led from head store 1 in a tunnel 3 to and through power plant 4 for gathering in a return store 5. From the return store 5 water is led in tunnel 6 to a secondary store 7. Wave energy — earlier known method — generated b arrangement 13 operates a pump piston 8, at which water from store 7 will be presse through back valves 10 and back to the head store 1. In pump house 11 there is equip ment for an alternative operation of pump piston 8 with or without a combination wit wave energy. According to figure 3 water is led from head store 1 in a tunnel 3 to and through power plant 4 for gathering in a return store 5. From the return store 5 water is led in tw tunnels 6 mounted side by side in two pump pistons 8 and in a tunnel 7 to a pump store 12 The two tunnels 6, which are attached at their ends, are surrounded by pump pistons 8 wit upper and lower chambers with intermediate bottom and moveable valves 9. Tide-water wind and/or wave energy — earlier known methods — generated by arrangement 16 operat the two pump pistons 8, which are coupled together in pump house 14. The two pum pistons 8 have working moments in pairs at which water from the lower chamber "of th pump piston is pressed out through back valves 10 and back to the head store 1 at the sam time as water from the upper chamber of the pump piston is pressed through back valves 1 and back to head store 1. Water from pump store 12 establishes overpressure and wate from the two. tunnels 6 establishes negative pressure. In pump house 1 there is equipmen for alternative operation of the two pump pistons 8 with or without a combination wit tide-water, wind and/or wave energy. According to figure 4 water is led from head store 1 in a tunnel 3 to and through power plant 4 for. gathering in a return store 5. From the return store 5 water is led in tunnel 6 to a secondary store 7. When bursting an explosive or rapidly burnable substanc rran ed in a it 8 s eciall and suitabl modelled for this wate a e t m as the gate 12 falls down, allowing water from secondary store 7 to stream down into spa released after bursting. The gases from bursting are carried off in pipe 14 to the gatheri arrangement 15. Before the pressure, developed at the bursting, has stopped working, t gate 9 falls down, preventing the water from head store 1 to be pressed back into retur store 5. The elevator 1 1 at first lifts gate 12 and after that gate 9, and the arrangement adjusted for repeated bursting. According to figure 5 water is led from head store 1 in a tunnel 3 to and through power plant-4 or gathering in a return store 5. From return store 5 water is led in a tunnel to a secondary store 7. When bursting an explosive or rapidly burnable substance arranged i a pit 8, specially and suitably modelled for this, water is pressed out from the store 7 at th same time as the gate 9 falls down, preventing water from the head store 1 to be presse back into the return store 5. Gases from the bursting are carried off in pipe 14 to gatherin arrangement 15. A gate 12 is closed at the bursting. The elevator 1 1 lifts gate 9 and gate 1 is opened and the arrangement is adjusted for repeated bursting. According to figure 6 water is led from head store 1 in a tunnel 3 to and through power plant 4 for gathering in a return store 5. From the return store 5 water is led in tunnel 6 to a secondary store 7. When bursting an explosive or rapidly burnable substanc arranged in a pit 9, specially and suitably modelled for this, piston 8 is lifted, at the sam time as water from the store 7 is streaming down into the space released after bursting Gases from bursting are carried off in pipe 14 to gathering arrangement 15. The piston sinks by its own weight, thus pressing water through back valves 10 and via pipe back int the head store 1. Within the frame of the invention it is possible, of course, to vary the plants and th means to push aside the water; also, a secondary store 7 is not always needed. The retur store 5 and the secondary store 7 can, of course, also form a single, common store.
