Description

The present invention relates to an energy converter according to the preamble of claim 1.

From the DE 199 07 180 C2 is a buoyant energy converter out, which has a liquid flow around a cylinder in the center of a wave with force-absorbing profiles is arranged. The cylinder can be positioned in a river with the help of floats and a variable height anchorage. The shaft is rotated by the flow in the cylinder.

From the publication EP 1 916 415 A1 an energy converter with a supply channel for a medium and a turbine downstream of the supply channel is known, wherein the turbine wheel, a transducer wheel is connected downstream such that the offset by the medium in rotation torque converter wheel for rotation of the turbine wheel is accelerated.

The object of the present invention is to provide an energy converter which operates efficiently and, in a relatively simple and compact construction, can convert the energy of a fluid flowing in a pipe part into energy.

This object is achieved by an energy converter having a supply channel for a medium and a turbine shaft connected downstream of the supply channel, wherein the turbine wheel is followed by a converter wheel, such that the medium can be accelerated by the rotated converter wheel for rotation of the turbine wheel.

In the invention, the transducer wheel is rotatably mounted on a rotatably mounted on the turbine shaft hollow shaft. The transducer wheel preferably has between two congruently arranged and spaced circular disks from its center outwardly extending and outwardly opening channels, in which the medium is guided in a rotation of the transducer wheel to the outside. The channels preferably each comprise a first region extending radially outwards from a central prechamber assigned to all channels and a second region angled radially outward relative to the first region approximately in the circumferential direction of the transducer wheel and opening outwards.

The channels are expediently formed in each case particularly by baffles arranged between the circular disks.

Characterized in that the speed of the transducer wheel is increased differentiated by a drive motor according to an embodiment of the invention, the pressure difference is increased, which is between the pressure of the medium in the supply channel and the pressure in the region of the turbine wheel. This advantageously results in a much greater flow velocity of the medium in the feed channel, d. H. a much greater kinetic energy of the medium. If one assumes the same output of a conventional wind turbine, the diameter of the turbine wheel of the energy converter according to the invention can advantageously be comparatively small. Furthermore, because of the large number of blade parts of the turbine wheel combined with the corresponding number of stator blade parts of the guide blade ring of the molded part, the efficiency over the conventional wind turbine is substantially increased. For the same power of a wind turbine and the present energy converter, the construction of the present energy converter can be relatively small. Advantageously, a shutdown of the present energy converter at high flow velocities of the medium in the supply channel is not required. Conventional wind turbines, however, have to be switched off at high wind speeds. By enclosing the present energy converter can be harmful to the environment influences such. As noise or, for example, occurring in low sunshine shadow strike can be avoided. Injuries to birds, such as wind turbines, can be ruled out in the operation of the present energy converter.

Advantageously, the present energy converter can be relatively inexpensively manufactured, transported and mounted because of its compactness and small size. Since all components of the present energy converter can be arranged near the ground, the structural design can be relatively simple. The present energy converter is preferably relatively insensitive to lightning. In the case of sudden gusts of wind no damage is to be feared.

With the generator driven by the turbine wheel of the present energy converter, constant power generation can be achieved by adjusting the speed of the converter wheel to set a constant volume velocity of the medium in the supply passage. The hereby with increased inflow velocity flowing medium, in which it is z. B. is air, additionally sets the torque converter in rotation and drives an additional gear on an additional generator. Depending on the flow speed, a differentiated speed increase is optionally output to the converter wheel with the drive motor in order to change the inflow speed in such a way that the turbine wheel flows around optimally. This is one Changing the angle of attack of the blade parts and the vane parts not necessary.

In a preferred embodiment of the energy converter according to the invention, the supply channel is formed by a pipe part attached to a machine frame, wherein on the side facing the turbine wheel side of the pipe part in the end portion of the pipe part projecting into a molded part and is fixed to the machine frame. The molded part is designed such that it directs the medium from the longitudinal axis of the tubular part in the direction of the inner wall of the tubular part. Appropriately, the molding is conical and arranged concentrically to the pipe part. The molded part of a preferred embodiment of the energy converter according to the invention has on its outer periphery Leitschaufelteile, each extending in the direction of the longitudinal axis of the tubular member and the same uniformly spaced on the outer periphery thereof. In this way, between each two adjacent stator blade parts, a corresponding region of the outer periphery of the molded part and a corresponding region of the inner wall of the tubular member, a flow channel is formed which leads to the blade parts of the turbine wheel.

In a preferred energy converter, the blade parts of the turbine wheel are evenly spaced about a circumference of the turbine wheel. They extend from the molding away to the side of the transducer wheel and are inclined in the circumferential direction of the turbine wheel. The number of blade parts may correspond to the number of blade parts or may differ slightly to avoid noise.

The turbine wheel is preferably connected to a turbine shaft, which is rotatably mounted in the machine frame. The side facing away from the turbine wheel of the turbine shaft may be rotatably connected to generate electricity with a generator. Between the side of the turbine shaft facing the generator and the generator, a transmission can be arranged, the transmission of which can be expediently changed. In order to enable the generator to be uncoupled from the turbine wheel, a coupling part for coupling and uncoupling the generator can be arranged between the gearbox and the generator.

In a preferred development of the energy converter according to the invention, a funnel-shaped inlet channel part is arranged on the side of the supply channel facing away from the turbine wheel, by means of which an additional medium flowing outside the energy converter can be introduced into the supply channel. The longitudinal axis of the inlet channel part may be inclined with respect to the longitudinal axis of the feed channel, preferably at a right angle. In a preferred application, the additional medium may be a wind trapped by the inlet channel part. The inlet channel part can be rotated relative to the longitudinal axis of the feed channel.

The medium used is particularly preferably air. In a further preferred embodiment of the invention, an atomizer unit is arranged in the feed channel, preferably on the side remote from the turbine wheel, through which a liquid or vapor medium can be introduced into the feed channel, which is preferably water, atomized water droplets or atomized Oil is trading.

8th to 11 Further developments of the invention.

According to 1 comprises a preferred embodiment of the energy converter according to the invention 1 a machine frame 10 to which a transducer wheel 50 and one with 80 designated turbine wheel are rotatably mounted. More specifically, the turbine wheel 80 with a turbine shaft 81 rotatably connected, in one in the machine frame 10 mounted bearing flange 56 is rotatably mounted. At the turbine wheel 80 opposite side of the turbine shaft 81 is a generator 85 rotatably at the turbine shaft 81 mounted, which upon rotation of the turbine shaft 81 generates electrical energy. The generator 85 is on console parts 83 and 86 attached to the machine part 10 are connected.

With the machine frame 10 is also a drive motor 57 connected, its output 58 a first pulley 51 wearing. The first pulley 51 is over a belt part 59 with a second pulley 60 connected, the rotation with a hollow shaft 55 connected is. In this way, the rotation of the drive motor 57 over the first pulley 51 , the belt part 59 , the second pulley 60 and the hollow shaft 55 on the transducer wheel 50 transfer. The hollow shaft 55 is with the help of a bearing flange 56 on the machine frame 10 stored.

The bearing flange 56 encloses a first bearing part 53 for the storage of the hollow shaft 55 , From the first storage part 53 is a second storage part 52 for the storage of the hollow shaft 55 axially spaced, wherein the second bearing part 52 in one, preferably in one piece with the bearing flange 56 formed, axially extending extension part 49 is stored.

It should be noted that the transmission of the rotation of the drive motor 57 on the transducer wheel 50 can also be done in a different way.

With the machine frame 10 is a serving as a supply channel pipe part 100 connected. This will be the machine frame 10 facing the end of the pipe part 100 preferably in a receiving ring 92 held on the machine frame 10 is mounted.

In the machine frame 10 facing end portion of the pipe part 100 there is a molding 90 , the rotation on the receiving ring 92 is attached and a to the machine frame 10 has conically widening shape, wherein at the bottom or on the machine frame 10 facing end of the conical molding 90 in the circumferential direction preferably uniformly spaced guide blade parts 91 are fixed, extending from the molding 90 from radially outward to the inner wall of the pipe part 100 extend. The vane parts 91 form a vane ring. The part facing away from the molding, lower areas 94 the vane parts 91 are preferable, as is clear from the 3 particularly clear, compared to the upper, axially extending portions 95 the vane parts 91 in the circumferential direction of the molded part 90 angled.

Below the pipe part 100 and also below the vane ring 93 is the turbine wheel 80 that with the turbine shaft 81 rotatably connected.

The scoop parts 87 of the turbine wheel 80 run from the molding 90 off to the side of the generator 82 towards and are in the circumferential direction of the turbine wheel 80 opposite to the areas 94 the vane parts 91 inclined. In this way, a particularly effective rotation of the turbine wheel 80 reached.

Below the hollow shaft 55 of the turbine wheel 80 is the transducer wheel 50 arranged and non-rotatable with the hollow shaft 55 connected.

According to 4b includes the transducer wheel 50 between two circular disks 51a and 51b in the circumferential direction evenly spaced channels 48 , each from the center 47 the transducer wheel 50 extend radially outward and just before the outer diameter of the transducer wheel 50 at an angle, which is preferably 90 °, against the direction of rotation of the transducer wheel 50 run. The channels open up 52 radially inward in a common annular antechamber 46 that the annular hub part 54 the transducer wheel 50 surrounds. The hub part 54 expediently runs with his, the disc 51a facing area 54a arcuate from the longitudinal axis of the transducer wheel 50 outward. This is a particularly good and vortex-free flow of the medium from the antechamber 46 into the channels 48 ensured. Above the arched area 54a can the hub part 54 with his area 54b concentric with the longitudinal axis of the transducer wheel 50 and to the annular channel spaced therefrom 41 the circular disk 51b run. It is also conceivable that the annular channel 41 the circular disk 51b according to 8th one to the longitudinal axis of the transducer wheel 50 directed constriction 41a has a higher flow rate of the fluid in the antechamber 46 to achieve.

The individual channels 48 are each through baffles 44 and 45 formed in the in the 4a shown way starting from the annular pre-chamber 46 each straight outwards and to form the channels 48 are angled so that in the straight line between two adjacent baffles 44 and 45 the approximately radially outward region 43 of the canal 48 and between the angled end portions of the baffles 44 and 45 at a preferably right angle to the radially outwardly extending region 43 extending area 42 is formed.

Upon rotation of the transducer wheel 50 through the drive motor 57 in the in the 4a shown direction of rotation undergoes a in the channels 48 medium located by the rotational movement at a speed n a centrifugal force Fz1. This centrifugal force Fz1 is determined by the peripheral speed v1 at the radius r1 and the mass m of the medium. The formula for centrifugal force is:

The formula for the peripheral speed is: v1 = 2 * r1 * π * n

The centrifugal force Fz1 pushes the medium in the channels 48 outward. At the radius r2, just before the right-angled curvature of the channels 48 applies to centrifugal force:

The centrifugal force Fz2 accelerates the mass m of the medium to a speed v3, taking into account the friction loss. At this point, ie just before the curvature of the channels 48 is the kinetic energy for the mass m of the medium:

The medium is characterized by the curvature of the channels 48 deflected counter to the direction of rotation and experiences after the curvature of a speed v4, which is smaller than the speed v3 due to the friction losses. This results in the kinetic energy:

The medium leaves the transducer wheel 50 with a kinetic energy W4. This creates a recoil with the same energy. This energy helps the transducer wheel 50 drive.

In the illustrated process arises in the antechamber 46 a negative pressure that causes the atmospheric external pressure 62 causes the medium in front of the transducer wheel 50 accelerated and through with 41 designated annular channel ( 4b ) the transducer wheel 50 is supplied. By a speed increase by the drive motor 57 driven transducer wheel 50 the pressure difference ΔP can be increased.

When the transducer wheel 50 through the drive motor 57 is set in rotation, the medium in the in connection with 4a way described in the channels 43 the transducer wheel 50 pushed outward, which is why in the area below the turbine wheel 80 that in the ring channel 41 is rotatably arranged, a negative pressure arises. This has the consequence that the medium from the pipe part 100 through between the vane parts 91 formed channels because of the mentioned negative pressure and because in the pipe part 100 prevailing atmospheric pressure 62 towards the blade parts 87 flows. This is the turbine wheel 80 rotated and transmits its rotation through the turbine shaft to the generator 85 which generates an electrical energy corresponding to the rotation. The named volume flow 40 is particularly good from the 6 seen.

The vane parts 91 are preferably according to 3 curved so that they are down in the direction of rotation of the turbine wheel 80 point. The molding 90 and the vane parts 91 be, as already mentioned, by the receiving ring 92 on the machine frame 10 held.

Through the molding 90 becomes the volume flow 40 so deflected that on the blade parts 87 of the turbine wheel 80 an optimal pressure is applied. About the conical molding 90 becomes the volume flow 40 to the ring channel 41 between the molding 90 and the recording ring 92 directed. As a result, the speed of the medium is further increased, which also a further increase in the pressure on the turbine wheel 80 entails.

According to 7 it is conceivable, a funnel-shaped inlet channel part 103 provide, the longitudinal axis, for example, perpendicular to the longitudinal axis of the pipe part 100 runs and that via an arcuate channel part 104 swiveling in a turntable 102 is mounted, with the upper end of the pipe part 100 connected is. In this way it is possible, the funnel-shaped inlet channel part 103 around the longitudinal axis of the pipe part 100 to turn it, for example, into a with 105 designated wind direction can be pivoted. For example, thereby the wind of a ship can be collected when the energy converter according to the invention 1 is arranged on a ship. The case by the Wandlerrad 50 generated pressure difference ΔP is then by the wind 105 reinforced dynamic pressure. This pressure accelerates the mass m of the medium to a speed v5. This results in a turbine wheel 80 acting kinetic energy:

To further increase the kinetic energy can in the pipe part 100 an atomizer unit 101 be provided over that in the pipe part 100 located medium, which is preferably the ambient air, a liquid, for. As water or a vapor-like medium can be supplied. This additional medium is due to the aforementioned volume flow 40 entrained and also accelerated to the speed v5. It plays the length 6 of the pipe part 100 ie the distance between the atomizer unit 101 and the turbine wheel 80 a crucial role.

The kinetic energy of the turbine wheel 80 is with high efficiency on the turbine shaft 81 transfer ( 2 ). For example, the high speed of the turbine shaft 81 via a gearbox 82 reduced, wherein the corresponding torque is increased. The gear 82 is according to 2 preferably with the already mentioned console part 83 connected. With 84 is in 2 denotes a coupling part through which the transmission 82 with the input of the generator 85 can be connected.

It should be noted that the present energy converter 1 can be mounted in different positions depending on requirements. The longitudinal axis of the energy converter 1 may preferably be oriented vertically or horizontally. The shape and the number of channels 48 the transducer wheel 50 , the axial dimension of the transducer wheel 50 as well as the dimensions of the pipe part 100 can in terms of the effectiveness of the energy converter 1 be determined and optimized.

In connection with the 9 to 11 a further embodiment of the energy converter according to the invention will be explained. This embodiment is particularly well suited for mounting on roofs of skyscrapers or the like. Details of 9 to 11 already related to 1 to 8th are explained in the appropriate way. In the apparent manner, the energy converter is preferably on a mast 123 or the like mounted.

At the outwardly opening pipe part 100 ( 9 ) is an inner profile part 112 attached, with a profile area 113 the pipe part 100 surrounds. The profile area 113 extends in the direction of the transducer wheel 50 , Furthermore, the profile part comprises 112 another profile area 114 , starting from the transducer wheel 50 to the profile area 113 leads away from the side and at the same time serves to cover the generator and the drive space.

The profile part 112 is coaxial with the preferably horizontally extending longitudinal axis or to the center 47 arranged. The profile part 112 is preferably a round molding, which is profiled so that the flow 106 is accelerated on the profile contour, being similar to the airfoil profile of an aircraft at the top of the profile part 112 a negative pressure is created.

One on the profile part 112 centrically mounted outer profile ring 115 experiences on its outside a flow around 108 and on its inside a flow 107 , The flow around 107 strengthens the flow 106 and thus increases their speed. The flows around 106 . 107 . 108 all lead in the direction of the "expiring" wind flow 111 , The wind direction of the incoming wind flow is with 105 designated.

The flow 106 with the increased speed that breaks out of the transducer wheel 50 escaping air and thus accelerates the outflow 109 at the transducer wheel 50 , This in turn causes a negative pressure in the transducer wheel 50 and thus a further increase in the pressure difference Δp after the turbine wheel 80 , This will cause the inflow velocity 110 on the pipe part 100 increased.

The outflow 109 at the transducer wheel 50 causes a recoil at the transducer wheel 50 as already explained above, and sets the transducer wheel 50 in rotation. This energy can z. B. via a transmission 117 ( 11 ) an additional generator 116 be fed and converted into electrical energy.

By the drive motor 57 is preferably differentiated a certain speed at the transducer wheel 50 generated. This differentiated speed influences the inflow 110 in front of the turbine wheel 80 and serves at different fluid velocities, e.g. As wind speeds to drive in the optimum range of the turbine. This means that an adjustment of vanes and an adjustment of the turbine blade is not required. The energy of the turbine wheel 80 is about the gearbox 82 the generator 85 fed, as already explained above.

A part of the generated energy (eg electrical energy) can according to 11 for driving a pump 120a to be used from a water store 118 For example, a lake or a sea, water over a pipe 120b a high lying pool of water 119 supplies. This supply always takes place when there is a so-called surplus of, for example, electrical power. If power surges are suddenly required in the electrical network, the supply line is used 121b and an adjustable throttle 121 the sprayer shown schematically 101 Supplied with water. Here, the feed pressure is dependent on the height of the water column 122 , The additionally injected, atomized water is entrained by the wind and thus the incoming mass is increased, whereby the energy generated is increased, as already explained above.

The benefit of relating to the 9 to 11 explained embodiment of the energy converter according to the invention is that it can also be used as a so-called pumped storage plant. The additional power required does not have to be generated exclusively by the power plant operators.
