Definitions

  • the invention relates to an internal axis rotary piston device for water energy power generation according to claim 1, the use of the internal axis rotary piston device and a method for operating an internal axis rotary piston device.
  • Turbines for power generation are well known, with Francis or Kaplan turbines being well suited for large volume flows from a storage height of approx. 3m and Pelton turbines for very great heights.
  • the demand for more sustainable energy that is also available as band energy opens up a market for turbines that would also work efficiently at lower pressures or volume flows.
  • Such turbines are already known and used in a variety of forms and configurations.
  • a turbine is shown in CH 702 901 A2.
  • DE 4015984 A1 discloses a rotary piston pump with eccentric control.
  • DE 2 258 712 A discloses a fluid operated device for performing a slow continuous rotation.
  • the object of the present invention is to provide an inner-axis rotary piston device which, when generating electricity from hydroelectric power, requires only a slight gradient in the water and can be flowed through bidirectionally by the water and in turn can be produced and operated cost-effectively. In addition, the usual major interventions in nature should be avoided.
  • the turbine according to the invention is used to generate electricity from water by means of a rotary piston device.
  • the advantage here is that the turbine according to the invention even uses drinking water lines to generate electricity.
  • low dammed riverbeds can also be used for winter use, for example, when other power generators such as photovoltaics or the like deliver less energy.
  • the inner-axis rotary piston device according to the invention supplies high-frequency revolutions, which in turn are well suited for operating generators.
  • Inner-axis rotary piston devices for power generation are well known, with Francis or Kaplan turbines being well suited for large volume flows from a water level of about 3 m and Pelton turbines for very large fleas.
  • the object of this invention is that the machine does not convert the energy of the flow velocity into rotation by deflection, but primarily uses the pressure for this purpose. It will use the principle of hydraulics, which uses the pressure via the difference in height between the water inlet and the inner-axle rotary piston device and is therefore more efficient than a classic, single-stage turbomachine even at low volume flow or pressure.
  • Piston machines are particularly well suited for the said area of application, because the fluid can only leave the piston chamber after the movement work has been carried out and the fluid flow is fed as completely as possible to the generator via the piston.
  • the Pelton, Francis, Kaplan or Ossberger turbines the very good level of efficiency decreases extremely if you are not working at the ideal operating point or is reduced to zero if the fluid flows too slowly and thus flows past the turbine blades that are under load.
  • the object of this invention is to present a machine that is particularly well suited for the use of water power and that works with a rotary piston.
  • the basic principle comes from the Wankel engine, with a particularly good variant being when the rotor is designed as a hypotrochoid and the housing as an epitrochoid.
  • the design with 4 piston chambers and 5 piston surfaces is particularly well suited and specifically the subject of this invention, especially for small volume flows and with a large gradient.
  • the advantage of this design is a good ratio of the outlet slots to the inlet opening and relatively sharp-edged piston corners that scrape away any dirt, e.g. algae.
  • Variants with several piston chambers make sense in river power plants with low pressure and high volume flow. Expressed in numbers, a design with a 1m diameter at the inlet and 5cm stroke results in 20 piston chambers. If the engine is elongated along the axis of rotation by 1 m, the result is a piston surface area approximately 4 times larger than the area normal to the flow from the inlet, with half the piston surface area being in the power stroke. If the flow rate through the machine is 1 m/sec. Spins the shaft at around 10Hz and the piston itself spins around around 180 seconds.
  • the length along the axis of rotation can be increased or decreased, which generates more or less power and a lower or higher number of revolutions.
  • the stroke can also be changed, e.g. reduced, which also increases the speed but also reduces the torque.
  • the object of this invention is, above all, to present the fluid flow in more detail for the best possible design.
  • the fluid is referred to as water, which is under pressure via a drop in height and thus serves as the drive medium of the inner-axle rotary piston device.
  • the water inlet takes place on the opposite side of the shaft for the power transmission to the generator, which is designed at least on this side as a pipe for the inflowing water or fluid.
  • the piston chamber is filled with water and pressure is applied to the piston, causing the piston to rotate.
  • the water then leaves the machine through slots in the housing.
  • the object of the invention is that by covering flow openings on the jacket of the second shaft and openings through the flow of fluid through the piston is controlled so that the majority of water only flows when the piston chamber enlarges, but not when it reduces again.
  • seals can be dispensed with.
  • seals can make sense, e.g. to compensate for manufacturing tolerances.
  • a further object of the invention is that instead of using a disc as the piston, as in the case of Wankel combustion, a piston and housing that are elongated along the axes of rotation are used.
  • the subject matter of the invention is that, as a result of the lengthening of the piston, fluid or water has sufficient energy, even with a slight gradient, to set the piston in rotation.
  • the flow slots and the piston surface can be designed in the desired size. For example, if these are larger than the inlet opening for the water on the front side, there is more surface area and therefore more power as a plan to the inflow surface. For this, the inflow speed slows down, or the speed.
  • the aim is to run as far as possible through the entire machine to the outlet, which can be even larger with the same flow cross-sections, so that a constant speed of the fluid is achieved and there are as few losses as possible due to acceleration and deceleration.
  • the object of this invention is that, for power generation, the rotational speed of the piston is not so high that too little water can flow and this creates a negative pressure in the piston chamber, which reduces the output.
  • a variant and object of this invention is that the cohesive forces are taken into account in general, but particularly at the outlet, for example by making the outlet thin-walled or opening more widely.
  • the performance can be optimized.
  • the elongated construction with inflow over the front side and the outlet at the side after the work has been done behind the piston has the advantage that a larger piston surface can be generated than the inlet cross-section, as the opening is large normal to the flow. By distributing and using the energy over a larger area, there is less back pressure. This property makes it possible to efficiently generate electricity even at low storage height and pressure.
  • the object of the invention is that the outlet slits from the housing are larger than the feed slits in order to build up as little resistance as possible during ejection and/or even to allow air to penetrate.
  • the object of the invention is that, in contrast to the known Wankel, the drive shaft from the generator has a smaller diameter than the opposite hollow shaft, which also serves as a pivot bearing.
  • the object of the invention is that the shaft, which is designed as a bearing in the motor, is also used in the machine as a tube for supplying fluid.
  • An advantage and object of this invention is that the rotary piston machine itself closes the connection from the storage area to the drain by braking or blocking it. As a result, only as many machines can be operated as are optimal, adjusted to the respective level. This makes it possible to keep the level as high as possible, which results in the maximum output per working machine.
  • Another object of this invention is that by controlling the speed, the level is always kept as high as possible despite the fluctuating amount of water, which ensures the maximum possible power.
  • the control can be done with pressure sensors, for example, whereby the level fluctuations during electricity production should not exceed 10%.
  • the relatively tight system which works as a pump by reversing the direction of rotation under power, removes any contamination from the inlet strainer.
  • a particularly favorable design for large machines is when they are made of sheet metal and, for example, the housing is filled with concrete.
  • the socket is advantageously protected with a stable metal grid and the water is cleaned before the pipe inlet with a filter or close-meshed steel grid to prevent the piston from jamming.
  • a concrete slab placed transversely in front of the inlet with a side inlet also forms a good protection option
  • a particular advantage compared to the turbines according to the state of the art is that a backwater is generated independently of the natural flow, and the residual water thus drains off faster than the service water.
  • algae especially filamentous algae
  • the subject of this invention is that the sharpest possible edges are provided, which separate the algae build-up.
  • One variant is the blades that cut up the algae that form.
  • Another object of this invention is that intentional algal growth is allowed to fill in manufacturing tolerances.
  • the excess algae growth is cut off with the sharp edges and/or the rotation.
  • the subject of this invention and the advantage of this Wankel technology, which works with low pressure and a flea gradient, is that the water is dammed up in the course of the river within the Flochiganschutzdamme and the dam wall can be folded down at Flochigan.
  • the damming elements are raised using a rope that is tightened. When high water is imminent, the rope is relaxed a little in order to lower the water and level through the resulting gaps between the elements without causing a surge that is harmful to the environment.
  • the rotary piston device is constructed in such a way that it has a cover plate and the cover plate has an embedded multi-chamber receptacle on the one hand and a rotational energy consumer on the other.
  • the rotary energy consumer can be designed as a generator or clutch or gear to transfer the energy to a generator.
  • an eccentric shaft is arranged to rotate in the multi-chamber receptacle.
  • the multi-chamber recording has x epitrochoid or hypotrochoid bulges, where the number x is greater than 1. Furthermore, a corner edge of a rotary piston is arranged in a rotating manner in the x epitrochoid or hypotrochoid bulges or expansion chambers. The corner edges slide along the contour of the epitrochoid or hypotrochoid bulge. The number of corner edges is related to the number of epitrochoid or hypotrochoid bulges. The number of corner edges is x+1. The corner edges of the rotary piston are arranged to rotate eccentrically. Another design is an x-1 variant in which the rotary piston has one edge, less has than the housing has epitrochoidal or hypotrochoidal bulges.
  • the edge of the rotary piston can actually be designed as a sharp corner or as a flattened corner.
  • the eccentric shaft has an eccentric base at one end and an inlet opening at the other end.

  • the eccentric shaft is rotatably accommodated in a piston.
  • the bulb represents a multi-sided prism. The corner edges form the edges of the prism.
  • an outflow slot In one area of the corner edges there is an outflow slot, with the piston being arranged to rotate in a housing and an inner wall of the housing taking up the shape of the multi-chamber receptacle, so that the inner wall is flush with the multi-chamber receptacle.

  • the fluid outlet opening can be interrupted by outlet slots. The same applies to the fact that the fluid outlet opening has a water outlet edge.
  • the axis of rotation transmits a rotational force to the rotary energy consumer via a transmission ratio of 1:1+y. This means that, for example, one revolution of the piston results in nine revolutions of the axis of rotation.
  • the axis of rotation can be a generator shaft, for example.
