Abstract

The invention relates to wind power plants, wherein an airfoil, using side rudders bringing about independent alignment of the airfoil to the wind direction, periodically slides upward or downward due to the wind force in an upward or downward direction, wherein the direction of motion of the airfoil is changed by tipping or rotating at the reversal points at the ends of the mast equipped with appropriate technical means. The airfoil thus generates kinetic energy in both phases of motion, which can be converted into electrical energy directly by means of a linear generator, or into mechanical energy by means of ropes, chains, or the like and optionally into electrical energy by means of a generator. Existing chimneys, ship and other types of masts, and trees can be used as the mast.

Description

Wind power plant with adjustable missile guided on a mast

Technical field of the invention:

The invention relates to wind power plants such as equipped with propellers or impellers windmills, the Darrieus rotor, the Savonius rotor and the classic windmills According to the invention slides a missile in the form of a wing or a tread wing with the aid of side elevators, which the self-alignment of the missile in the Wind direction cause periodically on a mast by the wind-induced buoyancy or downwards or downwards, wherein the direction of movement of the missile is changed by tilting or rotation at the equipped with appropriate technical means reversal points at the ends of the mast. The missile thus generates kinetic energy in both phases of motion, which can be converted into electrical energy in the mast or via ropes, chains or the like and a generator. The adjusting mechanism according to the invention is simpler, more responsive and the wind-effective surface slightly larger and aerodynamically favorable than conventional wind turbines, whereby the wind is used more efficiently.

State of the art

The depleting reserves of oil, natural gas and coal, including uranium, in the foreseeable future are increasingly forcing people to tap alternative and best-in-class sources of energy. This is primarily the sun, directly used by solar stoves, solar panels, photovoltaic cells or secondary products such as hydro, waves, tides, wind, thermal updraft and the like. The widespread use of the wind for power generation is currently wind turbines, which are found in the form of freestanding, built on heavy foundations towers with swiveling propellers and coupled generators in many places. In wind turbines, the area of the vanes exposed to the wind in terms of driving force is small, compared with the claimed area, the rotor surface. Since the wind increases with the distance to the ground and he steadies, you build the towers as high as possible, they must with considerable technical effort to catch the considerable, acting as buckling force on the tower wind pressure, which makes the equipment alone very expensive. High mechanical demands are placed on the very fast running rotors. The adjustment to the wind speed and direction is very complex and sluggish and leads to losses the exploitation of wind energy. The generator in the nacelle at the top further increases the cost of construction and maintenance.

Solutions are also found in the literature where useful energy is to be generated by dragons hanging free on ropes, cables and chains. Some of these solutions already offer the possibility to set up the generator on the ground and to use the stronger winds at higher altitudes, but they require a very complex control system and many safety measures for wind changes, in particular calm, use the wind energy only when climbing the kite the air traffic and have a large space requirement.

The kite-like solutions known from [5 -9, 12, 13] generate energy only in the ascent phase, while they consume energy in the sink phase, which in [13] e.g. must be applied by an additional wind turbine. The previously known kite-like devices also require a wide airspace, since they are carried by the winds in all directions.

The horizontal structures known from [10,11] have the disadvantage that they have to work in the area of low ground-level wind force and turbulent air and the entire plant has to be turned very laboriously in the wind direction. If the latter is not possible because they are also installed on or between mountain summits, as suggested in [11], only a limited use of a wind component is possible. Also, the technical solutions are not comparable to those for vertical solutions. The solution proposed in [14] describes a streamlined body oscillating in the flow, which draws energy from the flow, similar to a fish.

Task:

It was therefore the object to provide alternative wind power devices which do not have the disadvantages of the technical solutions described in the prior art.

The object has been characterized by what follows and in the claims

Devices and methods solved. The new plants according to the invention, which the

Expose wind energy through a buoyancy / missile, represent advantageous alternatives to the above-mentioned solutions of the prior art, including the earth-bound wind turbines. The advantages over the wind turbines of the prior Above all, technology can be seen in the significantly lower technical effort, which is ultimately reflected in the lower acquisition and operating costs.

In particular, these advantages can be summarized as follows:

(a) The area from which the flow energy of the wind can be withdrawn is the width of the buoyant body times its lifting height. It can be greater than that of simple means

Wind turbines are designed;

(b) the devices according to the invention can cost significantly better use the higher, wind stronger, turbulence poorer air layers by the use of guyed high masts. The starting wind speeds are lower, the upper limit speeds higher than with wind turbines. They can be easily secured against storms (c) the wind energy can be used much more efficiently because the buoyancy bodies used are self-contained, i. without (sluggish and expensive) mechanisms to rapidly changing wind direction and strength, so also gusts, set or the energy of gusts can be stored in the system;

(d) the device of the invention is largely freely scalable in size, i. it is also very large feasible, and there is thus less need of several plants (parks) side by side;

(e) the device according to the invention is also optically and acoustically more acceptable, because it is higher build, less visible and can be designed without significant wind turbine noise by propellers and without danger to birds;

(f) some variants according to the invention are to be produced and maintained by the simplest technical means. Therefore, they are especially suitable for the decentralized energy supply in the underserved regions of the earth as well as for direct generation of mechanical and thermal energy (without the detour via electricity).

(g) In addition to the high-flying structures they offer additional advantages in such a way that they occupy the airspace only very limited and locally defined and are easier to implement and approve. Summary of the invention

The invention relates to a device operating as a wind power plant essentially comprising a mast (72) and a missile (42) which is movably connected to the mast and at this periodically by wind power up and down is able to slip, by using in some embodiments movable vertical vanes (42c) and corresponding technical means (51-58), which accomplish the corresponding necessary alignment of the missile to the wind, not only in the buoyancy phase of the missile but also in the output phase vertical kinetic energy is generated, optionally by other technical means and Devices (6, R2-R5) can be converted into usable kinetic-mechanical or electrical energy.

The missile (42) according to the invention is constructed as a buoyant body and is suspended directly or indirectly on the mast (72) so that it can be driven upwards with an adjustable positive angle of attack driven by the wind and with a negative downward.

The missile (42) according to the invention is attached to a trolley (60), the latter may also be an integral part of the missile. The trolley (40) preferably has a correspondingly shaped and large opening or a correspondingly shaped profile for fitting the mast cross section or mast profile. Thus, the trolley or the missile (42) is guided along the mast.

The trolley (60) is held in most embodiments of the invention by holding and conveying means (61), which are preferably looped over rollers. In these cases, the trolley (60) and thus the missile is attached to one side of the looped holding means. In a particular embodiment of the invention may be mounted on the opposite side of a counterweight, which compensates for the weight of the missile including the holding devices, so that the missile can be moved by the least attacking wind forces.

In a further particular embodiment, which requires no further holding and conveying means, the trolley (60) is held by magnetic means on the mast (72) and in this case, as shown in Fig. 4, together with suitable means on or in Mast act as a linear generator. The said holding and conveying means (61) according to the invention can be endless ropes, belts, bands or chains, which are stretched over at least one upper and at least one lower deflection roller (51, 52) which are mounted on the top and bottom of the mast. When the missile moved by wind power moves, the conveyor rotates the rollers. On at least one of the axes mechanical equipment such as pumps, mills, saws, threshing machines are coupled, or an electric generator.

At the upper and lower turning point of the missile, so in the upper and lower part of the mast Umstellmittel (53 - 55) are mounted, which mechanically engage in the preferably vertical missile movement and change the buoyancy or downforce, preferably so that up a positive , down a negative buoyancy (downforce) is created, which adds to the weight of the body. Thus, energy is generated practically continuously in both directions of movement.

In some embodiments according to the invention, the trolley (60) or the missile (42) attached to it is fixedly connected to the holding and conveying means (61), whereby these and the deflection rollers (51, 52) the running or rotational direction when approaching and go down, the direction of rotation of the rollers can be rectified by means of a gearbox by freewheels.

In another embodiment according to the invention, means (57) are provided in or on the trolley (60) which engage in the respective opposite cable, belt, belt or chain strand (61) when the missile is moved up and down along the mast , so that no change in the direction of the deflection rollers (51, 52) and the holding and conveying means (61) must be made. This reduces the losses that can result from slowing down and re-accelerating roles and transport when changing the direction of up and down when this braking energy is not used elsewhere as described below. If the direction of travel does not change, the rollers and the alternator continue to move through the inertia of the movement of the rotor during the motion reversal and thus cause a continuous power output. The inertia can be increased, for example by a flywheel on the generator. In the embodiments with change of direction of the rollers, and in the other also, the inertia can be increased by a flywheel on the generator. The change between up and down can be on be done by changing the angle of attack of the missile (42), which by tilting about the tilt axis (80) of the missile, for example, triggered by mechanical Umwerfmittel (53, 54) or by electronic sensors (53a, 54a) and actuators in the Runners can be done. The tilting axis (80) of the missile is preferably arranged in its center of gravity.

The change between the up and down drive of the missile, or up and down sliding desselbigen along the mast can also be done according to the invention by rotating the missile by 180 ° about the mast axis. This is done in turn by mast mounted devices (stops) mechanically, electromechanically or electronically.

On the missile (42) according to the invention rudder (42c) are mounted on the lee side of the wing or wing, which cause the missile is automatically in the wind direction. This rudder can also have a pivot bearing (80a), preferably in the force-center of gravity of the missile, and thereby fold in the respective reversal points on the other end of the aircraft surface (windward side) or tilt, bringing the missile by the wind forces on the rudder automatically rotated and thus its angle of attack is changed, as shown by way of example in Fig. 3.

The holding and conveying means (61-63) run over turning points (51-55), which are essentially formed by reversing rollers (51, 52), deflecting means (53, 54) and mechanical or electro-mechanical stops (53a, 54a, 55). be formed near the reversing rollers.

The trolley (60) can be braked above and below resiliently or electromechanically when approaching the running ends, while at the same time the attached to the trolley missile (42) is changed for the movement in the opposite direction. Advantageously, the braking energy occurring in this case can also be used. When using springs, this is done by elastic reflection of the missile, for the recovery of electrical energy, this is done in the generator or in an additional electrical device.

The missile (42) is an airfoil, which is in the wind direction with the aid of side elevators. The angle of attack is preferably adjustable and fixed, or it may also change with the wind force. It is usually between 0 and 60 °, preferably between 10 and 45 °. The missile can be constructed in various ways. In the simplest case it consists of a canvas or a foil, which in one But it can also be realized as a flat plate or in a preferred embodiment as a flow-optimized profile-wing (42 B).

Other devices on the missile can adapt its properties to the wind speed, in particular, this can reduce the forces during storms and thus help secure. These means may be in the simple case elastic members (springs, elastic bands). Such means can also serve to store the energy of gusts, so they are not lost to energy use.

The mast (72) is advantageously braced at least above with ropes (71), whereby a multiple bracing at different heights is possible. In this case, the trolley (60) can then move either between two braces or by a special design of the guide on the mast even over several braces. For this purpose, it is then provided over its circumference with gaps for the passage of tensioning cable mounts on the mast and is held together magnetically.

Due to the possibility of bracing (s), the masts can cost much higher build than those for wind turbines. As a result, higher wind speeds can be used. Due to the fast, technically simple adaptation of the system according to the invention to the wind direction and speed, the wind energy is used more efficiently and by moving the generator to the ground there are further cost advantages. Buoyancy bodies, since they do not have to be exposed to different wind speeds and cantilevers like the propeller / impeller from inside to outside, can be made larger, safer (no centrifugal forces) and much cheaper in their wind-effective surface. The area from which the flow energy of the wind can be extracted corresponds to the width of the buoyant body multiplied by its lifting height. It can easily be made much larger than the rotor area of a wind turbine. The buoyancy bodies of the invention

Plants pose no danger to birds, they do not shred, as occasionally reported. Since you can build the masts higher, you can also better escape the field of view. As a mast, existing structures such as electric masts, chimneys, houses, ship masts or trees can be used.

Details of the invention

For all the embodiments according to the invention, a trolley (60), to which a missile is attached, runs up and down a mast (72), the missile is switched up and down between buoyancy and downforce and turned with a rudder in the wind direction ,

In Figs. 1, 4 and 6, the mast is fixed and the trolley (60) is running and rotating. In Fig. 2, 3 and 5, the mast rotates with the trolley, and in Figs. 1 to 3, 5 and 6, the linear movement of the trolley by rope, belt, chain or belt (61) and rollers (51, 52) in converted a rotational movement. In Fig. 4, the kinetic energy of the trolley (60) is converted directly into electrical energy with a linear generator. The masts are guyed with ropes (71) and fixed in ground anchors (44).

The ground anchors for the upper ropes are not shown.

The drivers (57), which put on the transport means (61) or grip, for example in the form of a slip clutch or clamp, or engagement in a chain make the connection between (60) and (61) ago. In Fig. 1 she attacks when climbing in the front, the Going down in the rear cable strand, in Fig. 2, 3 and 5 respectively in the right and left. The direction of rotation of the rollers (51, 52) remains the same in Fig. 1 -3, at 5 and 6 it changes.

The tilting axis of the missile (80) is set to be close to the center of buoyancy, with forces slightly greater on the windward side than on the leeward side, thus keeping the angle of attack positively positive or negative in the respective phase of motion, i. upwards upwind, downwards pointing downwards. The layer can be fixed by clicking or e.g. Magnetic couplings are further secured in the two end positions.

The missile and its axis extend in both directions perpendicular to

Plane. He has a recess or opening (42e) at the location of the cat (60) - see example Figure 5b. Its sides are braced for (weight-saving) stabilization with ropes. He has rudder (42c) on the leeward side. It can be designed in various ways, e.g. as a flat disc as in Figs. 1 and 3, or in a frame loosely clamped cloth (42a) as shown in Fig. 2, 5 and 6, which inflates like a sail when rising upwards, when descending down and thus better Buoyancy values than the disc generated and lighter. Or, as in FIG. 4, it is a flow-optimized profile (such as an aircraft wing) that generates maximum lift.

The angle of attack can be fixed in each case (stall) or motorized via a mechanism in the cat depending on the wind speed or more easily adjusted by elastic elements (pitch).

When the missile, driven by the wind, arrives at the upper derailleur (53), it is tilted about the axis (80). This can be done for example by the motion impulse itself and the wind power or electromechanically supported. The body now experiences negative buoyancy (= downforce), its windward side protrudes downwards, it slides wind-driven and down through its weight. There he is turned back to the climbing position, he rises again, etc. For safety, the cat meets up and down on sprung stops (53) and (54) and is elastic, so reflected as possible without loss of kinetic energy. Likewise, the "stops" can be realized electronically (as described in FIGS. 4 and 5). A dynamo may be coupled to the upper roller (51), firstly to assist electromechanically in shifting the kite above, or to provide power for firing the mast.

For maintenance or in the event of a storm, the missiles are fixed by interrupting the movement at the lower reversal point. The mast can also be folded by loosening a tether. The masts can be at one or more high points or not at all exhausted. As masts can also existing buildings, especially factory chimneys, but also higher houses, ship masts, electricity pylons or down knot-free trees are used.

In the following, the embodiments or examples are described in more detail:

FIG. 1:

A round mast is guyed at the lower and upper reversal point of the trolley with each

3 ropes. The linear ball bearing in the cat allows its up and down movement and rotation around the mast.

An endless belt runs over the rollers (51, 52), deflected over (52b and 52c), (in the image behind rollers) and connects the trolley (60) with the drive for the utility (6). The belt strands run one behind the other, the front always up, the back down. The ball bearing (51a) sits on the mast and carries the holder for the roller (51). The rotation of the roller (52) is transmitted via a gear and the vertical axis of rotation (61a) to the generator. (52e) is a ball bearing that sits on the mast and carries the rollers (52b, 52c). The sprocket (52f) is connected to (52) and engages the pinion (61b) which is fitted on (61a).

Since the missile (42) rotates with the wind around the mast axis, also the upper and lower cable holder must join in this movement. This is done by the rope itself when running up and down the trolley (60) and can be supported at high masts by wind vanes (not shown) on the upper and lower deflector. Alternatively, the upper and lower deflectors (51 and 52) can be tracked by the motor according to the position of the missile. FIG. 2:

The mast is rotatably mounted in a respective bearing (72c) above and below. These are installed at the top of the cable holders (73), at the bottom of the mast base (74). Solutions are possible with one to several combined masts. In a single mast in Fig. 2, the right system, the sprockets (61c) and the chain (6Id) would be missing. Here is a double system shown in tandem operation. Both are essentially the same, except that the device is needed only in one system, (which could also be installed separately from the mast and operated by more than these two missiles). The left missile runs up, the right down, then the right up and down the left. The weights of both thus compensate each other, and they can thus start even at lowest wind speeds. In such a system fewer guy ropes are needed. Such multiple combinations are possible in principle in the other embodiments. The rod (61a), which transmits the rotation to the utility device (6), is located in the center of rotation of the mast. The pinion (61b) engages through a wall opening of the mast in the sprocket (62).

FIG. 3:

Shown is the section of the upper part, built below as Fig. 2 left as

Single asset. In Fig. 1 and 2, the missile was tilted at the turning points and so switched from up to down. In Fig. 3, the missile remains fixed to the

Trolley connected, both are rotated, here by way of example, by the rudder (42c) about an axis (80a) on the stop (53) on the other, the windward side of the body is tilted. Fig. 3a shows the position when approaching the upper stop. There, the lever (42d) abuts the derailleur (53) and tilts the coupled rudder (42c). The result is shown in FIG. 3b. The structure stops at the springs (55), the wind detects the windward rudder and rotates trolley and missile together with the mast by 180 °, then it stands as in Fig. 3c. The wind pushes trolley and missile down, where the process reverses. The rudder, preferably for reasons of symmetry in duplicate, is attached laterally from the recess for the cat on the missile.

FIG. 4:

In Fig. 4a, the rotor and mast contents, so the linear generator drawn on an enlarged scale. The missile (42B) is designed as a wing profile. The round mast is fixed, the cat is guided by linear ball bearings (58) on the mast. Near the Reverse (53 a and 54 a), (inductively) a mechanism (42 k) is activated in the rotor, which tilts the missile in the direction of countermovement and possibly the inclination to the wind speed adapts (pitch). At the same time, the trolley (60) is electrically braked - via the generator. The linear generator consists of permanent magnets in the rotor and a segmented wire winding (6Of) and, to strengthen the magnetic field, stacked soft iron (60g) in the mast (72). In the Windungssegmenten (6Of) voltage is induced when passing the rotor, which is still rectified at the segments and via a common cable (60h) to an electrical station (6a) is passed. Or, of all segments, the voltage is derived separately and processed in (6a) (rectified, smoothed, etc.). If you choose a rotatable mast as shown in Fig. 2 and 3, the field magnet (permanent or electric) can be housed in the mast, and the voltage is induced in a coil in the trolley and brush with brushes transferred to the mast (no drawing) , To facilitate start-up at low wind speeds, the weight of trolley and missile can be compensated for by a counterweight (81) guided over an upper roller or by tandem operation described in FIG.

The regulation of the speed and thus the optimization of the performance can be done in all solutions shown on the extracted power. By the electric braking of the missile and trolley at the reversal points the impact can be prevented and the braking energy can also be used.

FIG. 5:

Fig. 5 shows a solution according to the invention, in which the trolley remains firmly connected to the rope, rope and rollers thus run back and forth. Advantage consists in a simpler mechanism in or on the trolley (no encompassing the clutches (57), Fig. 1). (5a) shows in detail the transmission mounted on the rear of the mast, (5b) the buoyant body. The roller (52) is connected to the sprocket (R2) via an axle passing through the mast. Both turn alternately left and right around the up and down running missile. (53a) and (54a) are sensors for the position of the trolley, which enable the electrical braking of the trolley via the alternator. (53, 54) represent rods that tilt the sail-like missile (as described in Fig. 2). (61 a) represents a spring mechanism that connects the trolley elastically with the belt (61) (or any equivalent means) and, for example Temperature variations occurring changes in length, compensates. The belt (61) runs up and down, rotating the rollers (51, 52) back and forth.

Fig. 5a illustrates a chain transmission which rectifies the direction of rotation of (R2) and translates the speed. The chain (6c) runs over (R3a) at the bottom, over (R3b) at the top; (R3a) and (R3b) rotate differently. The chain (6d) passes over (R4a, R4b and R5) in the same direction and drives the alternator. (R3) and (R4) sit on the same axis, but in each case with a freewheel (analogous to a bicycle rear axle) with the effect that the wheels (R4a, R4b, R5), as shown in Fig. 5a, turn in the same direction. An alternative solution would be two alternators with two freewheels. From the alternator, a cable leads to the electronics and consumers. The bottom plate (74) is secured with floor anchors against lateral displacement.

In Fig. 5b, the missile is formed by a cloth or film (42a) stretched in a double frame (42) and (42h) which inflates up and down when exposed to wind. The frame can be moved to holders on the mast in order to store it as possible in the center of gravity. The holders on the mast tilt when reaching the reversal points by a predetermined or dependent on the wind force angle. To stabilize the frame vertical rods are placed at the frame corners and in the center of the frame structure down and up, where tensioning cables can be attached. The cloth is lashed to the side frame so that it bulges in the desired, flow-optimal manner. A weight (81) is mounted on the trolley opposite rope and to compensate for the weight of trolley and missile, so that the system starts at lowest wind speeds. This can be achieved similar to in Fig. 2 by tandem operation of two systems.

FIG. 6:

Rollers and chain are shifted inside the fixed round mast tube and are thus protected against external influences. At the top left in Fig. 6, the rotor is shown enlarged. The coupling between inside and outside takes place via the magnetically coupled inner and outer runners (60b) and (60a). Both run on linear bearings (58) on the pipe wall. The outer part of the trolley rings around the mast, the inner can also be built. Rollers and rope do not rotate around the longitudinal axis with the missile in the Wind. The lower roller (52) is fixedly connected to the utilization device in the ground station (41). The inner part of the trolley is connected on one side with the chain, the band or the rope (61). On the other chain strand a counterweight (81) is mounted to compensate for the weight of the trolley and the buoyancy or missile. At the reversal points of the parts of the trolley can be mounted inside and / or outside stops with springs (as shown in the other figures).

This also results in the possibility that the outer cat part is divided over the circumference into several segments, which are held together magnetically with gaps between them, so that when going up and down the cat obstacles, such as guying of the mast can happen. Thus, the multiple guyed mast can thus have a lower flexural rigidity and can thus be built high at low cost.
