Definitions

  • the invention relates to a drive device having a turbine which is fixedly arranged on a rotatable shaft and which can be acted upon by a liquid, in particular water, and can thus be set into a rotary movement together with the shaft.
  • Such drive devices in which a rotatably mounted shaft carries a turbine are known. Water is applied to the turbine, causing it to rotate together with the shaft. The rotating shaft can then drive an assembly, for example a generator for generating electricity.
  • a disadvantage of this known drive device is that its efficiency is comparatively low, since relatively large losses occur, for example, due to bearing friction and air pollution. In addition, the residual energy of the water is no longer used after leaving the turbine.
  • the invention has for its object to provide a structurally novel drive device using a turbine acted upon by a liquid, in particular water.
  • the invention proposes that the Shaft is arranged vertically, that on the shaft concentrically surrounding an upwardly flared tube is firmly arranged, in the bottom region of which the turbine is arranged and which has an overflow in the upper edge region with a fixed collecting container for overflowing liquid arranged underneath , and that the turbine can be acted upon from below with the liquid via at least one downpipe starting from the collecting container.
  • a drive device designed according to this technical teaching is characterized by a very high degree of efficiency, since, due to the special design of the drive device, the liquid responsible for driving the turbine, which is preferably water, passes through a closed circuit so that the Energy from the water is used very well and converted into a rotary motion of the shaft.
  • the basic idea of the drive device is that - after starting the drive device after it has come to a standstill, the shaft and thus the tube has been brought to a certain speed of rotation, for example by an electric motor - the water from the upper collecting container through the preferably two to three downpipes is directed downwards so that the blades of the turbine are illuminated from below, thereby driving the turbine.
  • the tubes are closed at the bottom by a fixed base, into which aligned nozzles of the downpipes open.
  • a fixed base can be, for example, a sheet that fulfills the function of a drip tray that collects the water spray from the turbine blades.
  • the outlet nozzles of the downpipes are installed and aligned in this sheet.
  • a preferred development of the invention proposes that the downpipes guide the liquid to the blades of the turbine in such a way that the blades of the turbine are set in such a way that the liquid can be largely reflected by the blades with a radial component.
  • This training has the advantage that the waste water from the turbine directly strikes the inner wall of the tube and is thus transported directly upwards without it hitting the fixed floor, for example, as splash water. This further reduces losses.
  • the turbine is preferably a Pelton-like turbine. This is particularly suitable for the drive device.
  • the height of the tube is preferably approximately 10 to 12 m and the height of the downpipe approximately 8 to 10 m.
  • the height of the tube is approximately 2 m above the drop. This minimum head of approximately 8 to 10 m ensures that the turbine and thus the tube are driven at the required speed to exert the necessary centrifugal force on the turbine waste water and shoot the waste water up along the inner wall of the tube to the overflow allow.
  • a further development of the drive device according to the invention proposes that three downpipes are provided. These are to be arranged evenly around the circumference of the shaft. Of course, less or more than the three downpipes can also be used.
  • a preferred development of the drive device according to the invention proposes that helical baffles arranged radially upward at an angle are arranged within the tube with the shaft as the axis. These baffles give the tube additional torque, as the water presses against these baffles on its way upwards, thus generating the additional torque.
  • the baffles are firmly connected to the shaft and thus firmly to the tube.
  • the angle of the guide plates with respect to the vertical is preferably approximately 45 °.
  • the tube and / or the baffles be covered with a material that reduces air friction. This reduces friction losses to a minimum.
  • a second preferred development of the drive device proposes that the overflow of the tube has nozzles directed in this way, in particular nozzles curved in opposite directions to the direction of rotation of the shaft, through which the overflowing liquid flows so that the tube experiences an additional torque.
  • the rotating water at the upper end of the tube in the area of the overflow is used again for additional torque.
  • the water, which is forced outwards by the centrifugal force, is pressed through the correspondingly aligned nozzles with the formation of a dynamic pressure, so that a further thrust occurs.
  • the overflow preferably has an annular basin in which the liquid can be stowed and in which the nozzles are embedded.
  • This ring basin is firmly connected to the tube and rotates with it.
  • the drive device initially has a vertically aligned shaft 1, which is rotatably mounted in schematically indicated bearings 2.
  • the shaft 1 is surrounded by a tube 3, in the central axis of which the shaft 1 lies and which is firmly connected to the shaft 1, so that the tube 3 also rotates when the shaft 1 rotates.
  • the tube 3 widens conically towards the top, this conical widening at the bottom being larger in the bottom area for a short distance than in the area above it.
  • the upper edge of the tube 3 is essentially horizontally bent radially outwards and defines an overflow 4 with an annular basin 5, which is firmly connected to the tube 3 and defines the upper edge region of this tube 3. Curved nozzles 6 are embedded in the ring basin 5.
  • a Pelton-like turbine 7 with blades 8 is located in the lower region of the tube 3. This turbine 7 is also fixed on the shaft 1.
  • baffles 9 In the area above the turbine 7 and below the overflow 4 of the tube 3 there are helical baffles 9, which are also firmly connected to the shaft 1 and to the tube 3 and therefore also when the shaft 1 rotates together with the tube 3 and Rotate turbine 7. These baffles 9 are set at an angle to the vertical of approximately 45 °. In the drawing, the helical baffles 9 are only shown in sections. However, they preferably extend from the bottom of the turbine 7 to the overflow 4.
  • the tube 3 is closed on the underside below the turbine 7 by a fixed base 11 which does not co-rotate with the shaft 1.
  • This bottom 11 is formed, for example, by a sheet metal and is inclined downwards in the radial direction.
  • nozzles 12 of three downpipes 13 open. These downpipes 13 are guided upwards in the direction of the overflow 4 of the tube 3 and connected to an annular collecting container 14 which, like the downpipes 13 and the floor 11, is fixed together with the nozzles 12 is.
  • the height of the downpipes 13 is approximately 8 to 10 m, while the height of the tube 3 is approximately 10 to 12 m.
  • the drive device works as follows: As already mentioned, there is liquid 15, in particular water, in the upper, stationary collecting container 14. The supply line to the connected downpipes 13 is closed before starting the drive device by valves, not shown. To start up the drive device, the shaft 1 is first brought to a certain rotational speed, for example by means of an electric motor. As a result, the turbine 4 and the tube 3 together with the guide plates 9 rotate identically, since only the collecting container 14, the downpipes 13 and the base 11 are fixed as the only parts.
  • the valves in the downpipes 13 are opened and the liquid 15 falls from the collecting container 14 through the downpipes 13 down and passes through the inlets 11 in the bottom 11 such that the blades 8 of the turbine 7 are acted upon by the liquid 15 and thus the turbine 7 is driven. Since the unit is in a rotational movement in addition to the stationary parts, the liquid 15, which has acted on the blades 8 of the turbine 7, is subjected to a centrifugal force and is therefore thrown radially outward in the direction of the inner wall 16 of the tube 3.
  • the liquid 15 Due to the rotational movement of the tube 3 and due to the conical configuration, the liquid 15 experiences a force component upwards and therefore shoots in the direction of the overflow 4 in the vertical direction upwards along the inner wall 16 of the tube 3. Any splash water from the blades 8 of the turbine 7 is through the floor 11 caught. Due to the inclination of this base 11 downwards, the spray water is radially discharged and reaches the effective area of the tube 3. It is accelerated immediately and shoots upwards equally.
  • the liquid 15 collects in the area of the overflow 4 in the ring basin 5 and accumulates there with the formation of a dynamic pressure. Since 5 obliquely extending nozzles 6 are embedded in the ring basin, the liquid 15 is pressed through these nozzles 6, so that a third and last thrust occurs.
  • the liquid 15 is collected in the annular, fixed collecting container 14. After completion of this first circuit, the electric motor for driving the shaft 1 is switched off. At the same time, the liquid 15 is fed again via the downpipes 13 to the turbine 7 so that the whole process begins again in the form of a closed circuit.
  • the tube 3 is dispensed with entirely.
  • a turbine 7 with blades 8 is also fixedly arranged on a rotatable shaft 1. These blades 8 of the turbine 7 are acted upon either from one side or from the other, in particular from below or from above, with a liquid 15, in particular in the form of water, and set in rotation.
  • annular basin 5 In the radial area to the blades 8 of the turbine 7 there is an annular basin 5 in which inclined nozzles 6 are let in, the unit consisting of the annular basin 5 and the nozzles 6 also being arranged firmly on the shaft 1.
  • the nozzles 6 of the ring basin 5 also have an oblique course, as was the case in the first embodiment.
  • the blades 8 of the turbine 7 are acted upon by the liquid 15 in the form of water. After this exposure, the liquid 15 is flung radially away and collects in the radially arranged annular basin 5 and generates a dynamic pressure there. Through the inclined nozzles 6, through which the liquid 15 emerges due to the dynamic pressure, an additional torque is exerted on the shaft 1, which supports the torque exerted by the turbine 7, so that a second, additional thrust arises, which increases the efficiency of the Turbine 7 increased.
  • This alternative, second embodiment represents a separate invention independently of the first embodiment.
