Definitions

  • the present invention relates to a water-machine for the production of electrical energy with deformable piston.
  • Ecological water propulsion systems are known such as mills or systems adapted to convert the energy of water into electrical energy as occurs in hydroelectric power stations often located at waterfalls along rivers.
  • Said systems have the limit of being located along waterways and of requiring very complex plant engineering systems.
  • the object of the present invention is to make an ecological machine having limited dimensions, which is capable of producing energy from renewable source, which is simple to make and which can be used by users also with limited energy needs.
  • a cap suitable to superiorly close the first tank generating a second dry ambient communicating with the outside by means of a compensation chamber
  • crankshaft rotatably supporting a plurality of hollow pistons suitable to contain water
  • each piston providing an inlet pipe of the water whose flow is regulated by at least a charging valve, a discharge valve of the water, and at least a pressure changing pipe with associated a pressure changing valve suitable to selectively put the internal ambient of the piston in communication with said second dry ambient in a phase of water charging and with said first dry ambient in a phase of water discharging,
  • said piston being selectively deformable by means of actuating means between an expanded configuration wherein the volume of the internal space of the piston is maximal, and a squeezing configuration wherein the volume of the internal space of the piston is minimal.
  • figure 1 shows a side view of the machine according to the present invention
  • figure 2 shows a front view of the crankshaft
  • figure 3 shows a front view of a rigid piston
  • figure 4 shows a side view of the piston in figure 3;
  • figure 5 shows a side view of a transmission
  • figure 6 shows a side view of a deformable piston
  • figure 7 shows a diagrammatic, top plane view of the deformable piston in open expanded position
  • figure 8 shows a diagrammatic, plane view of the deformable piston in closed squeezed position.
  • a machine 100 for generating electrical energy comprises a supporting structure 9 adapted to support a crankshaft 8, a chain drive 12 and an electrogenerator 10.
  • the crankshaft 8 rotatably supports hollow rigid pistons
  • a bell-shaped tank 15 is lowered upside down from above thus generating, by means of known physical phenomena, a dry ambient 18 pressurized at pressure P2.
  • Bell 15 is completely surrounded by water 161 , above the free surface of which a dry ambient 17 is provided which is pressurized at pressure PI less than P2.
  • Said ambient 17 is closed by a sealing cap 3 and arranged in communication with the external ambient at atmospheric pressure by means of a compensation chamber 2 with compensation valves 1 and internal ambient at pressure P3.
  • P3 is equal to PI ; during the process the variations of PI shall require compensating as it will become more apparent below.
  • All pistons 5 are in communication with the watery ambient above by means of flexible inlet pipes 14 with flow controlled by charging valves 13.
  • the pressure inside the pistons 5 is controlled by three-way pressure changing valves 6 adapted to put the inside of piston 5 alternatively in communication with ambient 17 by means of flexible pipes 61 and with ambient 18.
  • An external compressor 200 permits to compensate the loss of pressure of ambient 18 by possibly removing pressure from ambient 17 if arranged in communication therewith.
  • machine 100 operates in the following way.
  • a computerized control unit 300 (not shown) controls the opening of valve 13 and consequently piston 5 is progressively filled hence determining the lowering by weight force and thus the rotation of shaft 8.
  • the flow induced by valve 13 is such as to determine the filling well before reaching the lower dead point PMI, substantially after approximately 90° of rotation.
  • valve 13 closes and the pressure changing valve 6 switches thus putting the internal piston 5 in communication with ambient 18; hence valve 4 discharges the water of piston 5 into the watery ambient below bell 16.
  • the switching of valve 6 determines the increase from PI to P2 of the pressure inside piston 5; otherwise the water would not be discharged.
  • the compensation chamber 2 intervenes to compensate this variation, which removes pressure from ambient 17 thus bringing it back to pressure PI equal to P3.
  • the excess pressure is discharged into the atmosphere by means of the valves 1.
  • PI is preferably less than the outside atmospheric pressure.
  • compressor 200 intervenes to compensate for the decreasing pressure in ambient 18, which eventually removes pressure from ambient 17 by emitting it into ambient 18 thus reintegrating the air volume inside piston 5 to pressure P2 which was previously discharged at PMS into ambient 17. Hence ambient 18 returns to the initial P2. Without compressor 200, water 161 would invade the inside of bell 15 at a certain point.
  • Transmission 12 connects crankshaft 8 to electrogenerator 10.
  • the above-described operating logic is managed by the control unit 300 and permits to keep the level of water 161 constant thus generating a natural flow of the water discharged from the pistons 5 from the bottom upwards thus always ensuring the presence of water 161 over bell 15 which is required to supply the pistons 5.
  • the control unit 300 monitors, at all moments, by means of suitable sensors, the position of the pistons 5, their level of filling, the pressure in all ambients, the rotation speed of shaft 8, the temperature in the different ambients, the status of the valves, obviously in addition to the electrical energy output.
  • Machine 100 depicted in the figures merely by way of example provides a single crankshaft 8 with four pistons 5; the logic of the procedure is also applicable to more complex systems with two or more parallel shafts 8 with a variable number of pistons 5 for each shaft 8.
  • Figure 6 shows a hollow deformable piston 50 formed by four rigid side surfaces 70 joined by soft deformable junctions 71. Said piston 50 is carried by a rigid structure 53 comprising two threaded vertical pillars 54.
  • figure 6 shows the inlet pipe of the water 14, pipes 61 for the communication with ambient 17, three-way pressure changing valves 6, a discharge valve 4 of the water, in addition to an additional charging valve 51 of the water immediately upstream of the piston.
  • the internal ambient 500 of piston 50 intended to house water 161 is connected to the inlet pipe 14 by means of a flange made with elastic material 52, for example rubber, which is also present between piston 50 and the discharge valve 4; it serves to adapt the tubular shape of the pipes 14 to the polygonal shape of piston 50.
  • elastic material 52 for example rubber
  • the three-way valve 6 comprises an opening 61 connected to the internal ambient 500 of piston 50, an opening 63 connected to ambient 18, and an opening 62 connected to ambient 17 by means of the pipes 61.
  • An actuator 64 controls said valve according to a logic which will be more apparent below.
  • a pair of actuators 65 controls the expansion and the squeezing of the internal space 500 of piston 50 by means of arms 66 associated to the side surfaces 70 of piston 50.
  • piston 50 mounted on crankshaft 8 comes after the following phases.
  • valves 13 and 51 are open thus allowing piston 50, which is in the expanded configuration in figure 7, to be charged; valve 6 puts the internal ambient 500 of piston 50 in communication with ambient 17 at pressure PI .
  • Piston 50 begins its lowering stroke stressed by the increasing weight of the water therein.
  • suitable level sensors control the closing of valves 13 and 51 ; valve 13 serves to prevent water from remaining in the inlet pipe 4; valve 51 ensures that pressure PI is kept inside the empty pipe 14 even after the switching of the three-way valve 6.
  • the control unit 300 controls the switching of valve 6 thus bringing the pressure within the internal ambient 500 of piston 50 to P2 to then discharge the water by opening valve 4.
  • valve 4 is closed and valve 6 (internal ambient 500 of piston 50 at pressure PI again) is switched.
  • Piston 50 in squeezed configuration raises pushed by the other pistons 50 mounted on shaft 8, and once at the PMS, is re-expanded to allow a new charging of water. And the cycle resumes as described above.
  • the squeezing of piston 50 permits to limit the dispersion of the air in ambient 18, towards ambient 17, i.e. limits the reintegrating work of compressor 200.
  • the energy used for the actuators 65 is less than the one used for compressor 200 in case of rigid piston.
  • piston 50 the expansion of piston 50 at the PMS before charging of the water generates a depression in the internal ambient 500 of piston 50 which promotes the charging of the water itself thus creating a kind of "suction" effect.
  • the motive thrust of piston 50 is hence increased because it is charged faster.
