Definitions
- the invention relates to an air turbine for exploiting ocean energy and for converting the energy into electrical energy.
- Such systems have become known, for example, from EP 0 000 441 A1 and GB 2 250 321 A. It is therefore a facility that exploits sea-level motion due to surface waves.
- Systems of this type are constructed as follows: They comprise a chamber which is open at its lower end and with this open end immersed in the sea. At its upper end, it also has an opening. There is further provided a pipe which serves to guide an air flow.
- the tube is connected with its one open end to the upper opening of the chamber. In the tube is an enclosed by this and coaxial with the tube arranged energy unit with a turbine rotor and possibly with a standing in driving connection with the rotor electrical generator.
- the mirror of the sea water within the chamber constantly rises and falls according to the waves of the sea; the wave motion thus acts into the chamber. With each lifting of the water level, a displacement of the air quantum in the chamber is contained. The air is displaced when lifting the water level and flows through the upper opening of the chamber and thus also through the pipeline in which the turbine is located.
- the turbine is thus an air turbine. It has a rotor with a
- the rotor disk carries a number of blades.
- One Housing together with the rotor flows through a space. This space has an axially flowed through channel and a radially flowed channel. See GB 2 125 113 A.
- the turbine is flowed through in two directions, corresponding to the raising and lowering of the seawater level.
- the invention has for its object to design a turbine according to the preamble of claim 1 such that the efficiency over the
- FIG. 1 The figures show a known air turbine in a schematic representation, namely Figure 1 in an axis-parallel section, and Figure 2 in an axial section.
- a rotor 1 comprises a rotor disk 2. This is rotatably with a shaft 3.
- the rotor disk 2 carries a plurality of rotor blades 4.
- a housing 6 forms an axial together with the Stromleittude 5
- the housing forms a radially flowed through channel section 9. This is followed by a cranked channel section 10, which flows in the radial direction, but has a small axial component (hereinafter referred to as "inclined Channel ").
- channel section 7 In the axially flowed through channel section 7 is a variety of
- Vanes 11 These are supported by the housing 6.
- Peak area 5.2 is a multiple of the axial extent of
- the Stromleit stresses 5 is about four times as long as the blade is wide. It should be at least twice as long as the blade is wide. The ratio may be, for example, 3: 1, 4: 1, 5: 1, 6: 1, 7: 1 or more. As can be seen, the entire area through which it flows comprises the following
- Channel sections An axially flowed through channel section 7, a manifold 8, a purely radially flowed through channel section 9, and an inclined
- Channel section 10 The flow is there predominantly radially, with a small axial component.
- the vane 11 provides a firm connection between the housing 6 and
- Stromleit Equity 5 reduces or avoids turbulence of the flow in the axial region. It reduces the cross section in the channel section 7 and therefore increases the flow rate. This reduces the occurrence of so-called dead water.
- the stator also contributes to this.
- the design of the sloped channel avoids backflow, which in turn reduces flow losses.
- FIGS. 4 to 11 show further embodiments.
- the embodiment according to FIG. 4 in turn has a guide blade 11 in the axially through-flowed channel section 7, but no guide blade radially outside the moving blade 4.
- the embodiment according to FIG. 5 also has a guide blade 12 in the channel section 9 through which it flows radially.
- the embodiment according to FIG. 6 has a guide blade 13 in the region of the bend 8.
- the embodiment according to FIG. 7 in turn has a guide blade 13 in the region of the bend. Further, a guide vane 12 in the radially flowed through channel section. 9
- the embodiment according to FIG. 8 has a guide blade 13 in the region of the bend, but close to the moving blade 4.
- the embodiment according to FIG. 9 has a guide blade analogous to that in FIG. 8, as well as a guide blade 12 in the radial channel.
- the embodiment according to FIG. 10 has a guide blade 11 in the channel section 7, which flows through axially.
- the axial channel section 7 is curved approximately S-shaped.
- the embodiment according to FIG. 11 has the same structure as that according to FIG. 10. However, in this case, in the radial channel section 9 there is again a guide blade 12.
- He have, which differ from a cylindrical contour. He can be club-shaped. He may have constrictions and extensions. He may even have a waveform as a contour - not shown here.
- FIGS. 12 to 15 serve above all to illustrate embodiments of the radially through-flowed channel region.
- the housing 6 and a housing wall 6.1 is bent.
- the bend is located directly radially outside the rotor blades 4, in the illustration according to FIG. 13 somewhat further radially outwards.
- the inclined channel section 10 is illustrated, starting immediately radially outside the blade 4 in FIG. 14, and slightly radially outside in the embodiment according to FIG.
- contour A of the rotor disk and the contour B of the housing or the contour of a cover disk C are designed such that the width X of the radial
- contour A of the rotor disk and the contour B of the housing or the contour of a cover disk C are designed such that the width X of the radial
