The object of the invention is to provide a device for converting energy from an oscillatory movement into electrical energy, with which a more efficient energy conversion is possible.

This object is achieved by a device for converting energy from an oscillatory movement into electrical energy, in particular from an oscillatory motion caused by water waves, according to the independent claim 1. Furthermore, an arrangement with several such devices according to the independent claim 22 is provided. Advantageous embodiments of the invention are the subject of dependent subclaims. The invention encompasses the idea of a device for converting energy from an oscillatory movement into electrical energy, in particular from an oscillatory movement caused by water waves, comprising:

a base body configured to perform an oscillatory movement due to an external oscillatory force acting on the base body, a conversion mechanism configured to convert the oscillatory motion of the base body into a rotary motion of a conversion element about an axis of rotation, wherein a major axis of the conversion mechanism, is formed substantially upright regardless of the inclination state of the base body in the oscillatory motion, and

a generator unit that is configured to convert energy from the rotational movement of the conversion element about the axis of rotation into electrical energy.

The device enables efficient energy generation by converting the oscillatory movement which the base body receives and which is caused, for example, by a wave movement of a water surface, into loss of electrical energy by means of a conversion mechanism and a generator unit. In the process of energy generation, the oscillatory motion executed by the base body is first converted into a rotary motion of a conversion element about a rotation axis, a main axis of the conversion mechanism being substantially upright in parallel motion (parallel to weight force) regardless of the inclination state of the base body in the oscillatory motion. Gravity) is formed. The conversion mechanism is pivotally mounted on a suspension in the top of the base body. Regardless of the inclination state or inclination angle of the base body, during the oscillatory movement, gravity keeps the conversion mechanism substantially in the vertical. The inertial mass of this "pendulum system" ensures that the conversion mechanism is essentially always aligned parallel to gravity.Also, this "pendulum system" can also be stabilized with the spin of a gyro or a rotating mass disk. Driven by the oscillatory movement of the device, for example by a wave motion of a water surface, the base body of the device performs a wobble / tumble motion, which by means of Conversion mechanism is converted into a rotational movement of a conversion element about a rotation axis. The conversion element is a component of the conversion device, for example a shaft / drive shaft, which is configured to transmit a force of the rotary movement. The conversion element is coupled to a generator unit which is configured to convert energy from the rotational movement of the conversion element about an axis of rotation into electrical energy.

A preferred embodiment of the invention provides that a further conversion mechanism is formed, which is configured to convert a vertical movement (oscillatory lifting movement) of the base body into a rotational movement of a further conversion element about a further axis of rotation or amplify. The further conversion mechanism is pivotally mounted on a further suspension (suspension point, pivot point) / arranged. The further suspension point is preferably arranged on the underside of the base body. Alternatively, however, the further suspension point can also be arranged at another point of the base body, for example on a side wall of the base body. The further conversion mechanism is configured to convert a vertical movement of the base body into a rotary movement of a further conversion element about a further axis of rotation. Alternatively, however, the further conversion mechanism can also be coupled to the conversion element of the conversion mechanism. At the other suspension point one end of a rigid arm (lever arm) is coupled. The other end of the rigid arm is attached to a fixed suspension point (outside the device). As a suspension point, for example, an anchorage in the seabed or a submerged under water network structure can be used. Here, the base body of the device, during the oscillatory movement, moves on a circular path with a radius of the length of the lever arm. Depending on the angle of inclination of the arm, the center of gravity of the base body (along the circular path) moves up and down. The up and down movement (oscillatory lifting movement) of the base body can be converted by means of the further conversion mechanism into a rotary movement of the further conversion element about the further axis of rotation (see also FIG. 2). In an expedient embodiment of the invention can be provided that the conversion mechanism and / or the further conversion mechanism is / are formed with at least one push rod assembly which is / are configured to transmit a force from the base body to the conversion mechanism and / or the further conversion mechanism. The push rod assembly is configured to transmit the oscillatory force of the oscillatory movement of the base body, from the base body to the conversion mechanism and / or the further conversion mechanism. While the base body performs an oscillatory movement, the conversion mechanism and / or the further conversion mechanism remains substantially at rest relative to the base body. The relative movement between the two coordinate systems, that of the base body and that of the conversion mechanism and / or the further conversion mechanism, is transmitted between the two systems by means of the push rod arrangement. In this case, the conversion mechanism and / or the further conversion mechanism can be formed with one or more push rod arrangement (s) in different orientation directions.

A further development of the invention can provide that the at least one push rod arrangement is formed with at least two push rods, preferably with at least three push rods. A push rod assembly having two opposing push rods may transmit an oscillatory force or motion of the base body in one direction (in one dimension) to the conversion mechanism and / or the further conversion mechanism. In order to completely transfer all components of the motion of the oscillatory movement of the base body to the conversion mechanism and / or the further conversion mechanism, two push rod arrangement can be used, each with two opposing push rods. The two push rod assemblies are then (crosswise) arranged at an angle of 90 ° to each other, so that the full range of motion of the oscillatory movement of the base body is covered. Such a push rod arrangement is independent of the direction of the oscillatory movement of the base body. In a push rod assembly with three push rods, the push rods are each arranged at an angle of 120 ° degrees (star shape in the horizontal plane) to each other. Here, the complete, two-dimensional, oscillatory motion of Basic bodies covered (three-dimensional movement space of the pitching / tumbling motion is projected onto a two-dimensional plane).

In an advantageous embodiment of the invention can be provided that at least one push rod coupled to a gear rod and / or a hydraulic piston. The transmitted by means of the push rod oscillatory force or movement of the base body can be transmitted by means of a coupling to a gear rod and / or a hydraulic piston. The gear rod and / or the hydraulic piston are part of the conversion mechanism and / or the further conversion mechanism and serve the purpose of redirecting the transmitted force or movement and / or convert into a rotational movement of the conversion element and / or the further conversion element. In a hydraulic embodiment of the invention, the individual push rods couple to one or more hydraulic pressure piston. In the hydraulic pressure piston, the transmitted oscillatory force or movement of the base body is converted into a hydraulic pressure (in pressure energy). The at least one hydraulic pressure piston is coupled, for example via a hydraulic pressure line to a pressure vessel, which is configured to temporarily store the energy of the hydraulic pressure and then release it again. With the energy stored in the pressure vessel can be driven by a substantially constant pressure delivery, a hydraulic motor or a hydraulic turbine (eg Pelton turbine). In the hydraulic motor / hydraulic turbine, the hydraulic pressure is converted into a rotational movement, wherein from the hydraulic pressure, a torque is generated, which is converted into a rotational movement in the hydraulic motor / hydraulic tines. The hydraulic motor / hydraulic turbine is coupled to the conversion element and / or the further conversion element and puts them into rotation. The energy of the rotational movement of the conversion element and / or the further conversion element about the axis of rotation and / or about the further axis of rotation is then converted by means of the generator unit into electrical energy (A / C or D / C - AC or DC). A hydraulic embodiment of the invention may comprise one or more of the following components: hydraulic pistons, pressure lines, pressure vessels, hydraulic motors, hydraulic tines, and / or shafts. A development of the invention may provide that the conversion mechanism and / or the further conversion mechanism is formed with a transmission. The transmission can be used to change a force or a torque of the rotational movement of the conversion element and / or the further conversion element about the axis of rotation and / or about the further axis of rotation. The transmission may in this case be selected from the following group of transmissions: gear transmission, friction gear, traction mechanism, helical gear, coupling gear, planetary gear and / or cam gear. For example, a relatively slow rotary motion can be converted into a fast rotary motion with the transmission.

In an expedient embodiment of the invention can be provided that the conversion mechanism and / or the further conversion mechanism is configured to rotate the conversion element and / or the further conversion element with a substantially constant frequency. A substantially constant frequency rotation is achieved, for example, in that the conversion mechanism and / or the further conversion mechanism is formed with a centrifugal governor or a spring force mechanism. As centrifugal force, for example, a so-called Wattscher controller or a Porterscher controller can be used. A development of the invention may provide that the conversion mechanism and / or the further conversion mechanism is stabilized. A stabilization of the conversion mechanism and / or the further conversion mechanism can be realized by a rotating flywheel. A rotating flywheel is on the one hand in a position to store part of the energy of the rotational movement of the conversion element and / or the further conversion element about the axis of rotation and / or about the further axis of rotation and on the other to effect a swirl stabilization on the "pendulum system" The flywheel is used here as a momentum store, which temporarily absorb the torque of the rotational movement of the conversion element and / or the further conversion element about the axis of rotation and / or about the further axis of rotation and then back to the At the same time, the rotating flywheel generates a spin on the "pendulum system", which also has a stabilizing effect. there The flywheel can be designed as a slow-rotating or as fast-rotating, heavy disc. As a stabilization of the axis of rotation and / or the further axis of rotation and the inertial mass of the "pendulum system" itself or serve a resting, heavy mass.

A preferred embodiment of the invention provides that the device is formed with a further generator unit which is configured to convert energy from the rotational movement of the further conversion element into electrical energy. The further generator unit is coupled to the further conversion element and designed to emit the energy the rotational movement of the other conversion element to convert the further axis of rotation into electrical energy.

In an expedient embodiment of the invention can be provided that in addition a rigid arm is formed, which couples to the other conversion mechanism. The further conversion mechanism is pivotally arranged about a further suspension point (pivot point), wherein the further suspension point is preferably arranged at the bottom of the base body. At the other suspension point movably coupled one end of a rigid arm (lever arm / moment arm), wherein the other end of the arm is connected via a rotary joint with a fixed suspension point. The fixed suspension point is in relative calm to the device or to the base body. This arrangement forces the base body into a circular path during the oscillatory movement. Depending on the angle of inclination of the rigid arm, the center of gravity of the base body moves up and down. The potential energy from this oscillatory up and down movement (lifting movement) of the base body is converted into electrical energy by means of the further conversion mechanism and the generator unit and / or the further generator unit

A preferred embodiment of the invention provides that the generator unit and / or the further generator unit are formed with at least one dynamo and / or a gyro generator. The at least one dynamo and / or gyro generator are designed to convert the kinetic energy or the mechanical energy of the rotational movement of the conversion element and / or the further conversion element about the axis of rotation and / or about the further axis of rotation into electrical energy. An advantageous embodiment of the invention provides that the at least one gyro generator is formed with a gyro which is configured to perform a rotational movement about a gyro axis of rotation.

A preferred development of the invention provides that the conversion mechanism and / or the further conversion mechanism is / are configured to rotate the conversion element and / or the further conversion element with a frequency that causes the rotation of the gyro around the gyro rotation axis at a system natural frequency , A substantially constant frequency rotation is achieved, for example, by forming the conversion mechanism with a centrifugal governor or a spring force mechanism. As centrifugal force, for example, a so-called Wattscher controller or a Porterscher controller can be used. An advantageous embodiment of the invention provides a starting mechanism, which is configured, the gyroscope in a start-up phase - in mechanical or electrical design, wherein in the electrical version of the generator is operated as a motor - to put in an initial rotation. In this way, the respective rotary mass of the multiple centrifugal generators at the beginning of the operation for generating energy is set in rotation, so that subsequently caused by the rotational movement of a support system Zwangspräzession the individual gyros takes place. The rotational movement of the carrying system serves continuously to drive the centrifugal movement, from which the electrical energy is obtained according to the dynamo principle. Preferably, a further development of the invention provides that the starting mechanism is configured, by utilizing a part of the driving force for the rotational movement of the conversion element and / or the further conversion element in the starting phase, to put the gyro compound in the initial rotation. The starting mechanism is formed, for example, with a centrifugally driven drive ring, which is preferably inclined axially, radially, or otherwise, with the drive ring coupled to transmit the drive force to the gyroscope to effect the initial rotation. In an advantageous embodiment of the invention can be provided that the conversion mechanism and / or the further conversion mechanism and the starting mechanism are formed cooperatively, such that a support system for the at least one gyro generator, during the start phase at least temporarily by the driving force for the rotational movement of the conversion element and / or the further conversion element decoupled and at the latest after completion of the start phase is again coupled thereto.

On the support system several centrifugal generators are arranged. Your storage on the support system allows a rotational movement of the gyro generators each associated gyro around a precessing gyro rotation axis. The dynamo principle is used to obtain electrical energy from the rotational movement of the gyro around the gyro axis of rotation. The efficiency of energy generation is substantially assisted by the fact that the relatively slow rotational movement of the conversion element about the axis of rotation, for example about the major axis of the conversion mechanism caused by the oscillatory movement of the base body, is translated into rapid rotation of the gyroscopes in the gyro precession can also be understood as a forced precession. The centrifugal generators rotate with the carrying system or with the conversion element about the axis of rotation and in each case (in addition) perform a precessing centrifugal movement. The rotational movement of the support system eventually leads to continuously triggering the rotation of the rotary mass, in which case a substantial increase in the rotational frequency takes place, namely the frequency of rotation of the support system to the frequency of rotation of the rotary mass of the centrifugal generators.

A preferred embodiment of the invention provides that the at least one centrifugal generators are formed with a coil device and a magnetic device which is arranged on the associated centrifugal mass. The magnetic device is preferably formed by means of permanent magnets. Their arrangement on the gyroscopic leads in operation to the fact that the magnetic device rotates in the coil field, so that according to the dynamo principle electrical energy is obtained. In an expedient embodiment of the invention can be provided that in the coil means coils are arranged distributed on a spherical shell.

An advantageous embodiment of the invention provides that the plurality of centrifugal generators are arranged on a support platform of the support system. On the support platform, the individual centrifugal generators are each freely rotatable about at least two axes of rotation, wherein the two axes of rotation need not necessarily be formed at right angles to each other. As a result, the Zwangspräzession the gyroscope is possible, which in turn is made possible by the rotational movement of the support system and the corresponding storage of the centrifugal generators on the support system. It may be provided that the plurality of centrifugal generators are mounted on the support platform of the support system so that upon rotation of the support platform, a respective housing of the centrifugal generators maintains its absolute orientation. In one embodiment, a current decrease of the centrifugal generators is formed free of electrical sliding contacts.

Preferably, a development of the invention provides that the base body is formed with a float. With the aid of this embodiment, the device is designed for a conversion of the oscillatory movement of water waves into electrical energy. The oscillatory motion received by the float is transmitted to the base body, which in one embodiment can itself form the float, followed by the described energy conversion chain.

An embodiment of the invention can provide that the base body is formed with an outer and an inner base body, wherein the inner base body is mounted in the interior of the outer base body by means of a floating mounting. The floating bearing is formed in an embodiment in which the inner base body floats in a liquid accommodated in the outer base body. The inner and the outer base body are movably connected in one embodiment via at least one lever arm. The carrying system with the several centrifugal generators is arranged in the inner base body. A training may provide that, alternatively or additionally, the outer and the inner base body connected to each other via at least one mechanical coupling are, so that a relative movement between the outer and the inner base body can take place.

In connection with the arrangement with a plurality of devices in one of the aforementioned embodiments, it can be provided that the network structure formed is designed as a star-shaped network structure. For example, the arrangement of the nodes and the edges connecting the nodes of the network structure in the manner of a spider web is possible. This circular shape significantly reduces the anchoring, logistics, supply and grid stability issues. Alternatively, however, the network structure can also be combined with other forms, e.g. Rectangles, diamonds, etc. may be formed.

If a floating network structure is formed, anchoring elements are arranged in an embodiment on the network structure, preferably at the edge, with which the network structure is fixed locally in the water.

In an advantageous embodiment of the arrangement can be provided that the floating network structure is anchored under water, wherein the plurality of devices are each coupled with a rigid arm to the floating network structure. An anchoring of the network structure, such that the network structure is completely floating below the water surface, allows the installation of the network structure within offshore wind farms. By installing the network structure below the water surface, free access, navigability and traversal of the system with ships / boats is still possible. In addition, the coupling of the multiple devices to the floating network structure by means of an arm or a cable, which can be converted into electrical energy even in deep waters, the potential energy from the lifting movement of the multiple devices. Anchoring of the multiple devices in the seabed is not necessary.

The several devices, which are preferably designed according to one of the previously described embodiments, float on the water surface. Anchor 54 are formed on the edge, with which the network structure 51 is localized. Via an electrical line 55, the energy obtained is tapped.

6 shows a device for converting energy from an oscillatory movement into electrical energy, in which a base body having an inner base body 60 and an outer base body 61 is formed. The inner base body 60 is floatingly supported in a liquid 62 received by the outer base body 61. The outer base body 61 is formed with a buoy shape. The inner base body 60 and the outer base body 61 are connected via a lever arm 63 which is connected to a mechanism 64 coupled, which is shown in Fig. 7 in detail. In operation, the outer base body 61 executes a rocking motion shown schematically in FIG. 6 by means of an arrow A.

In the mechanism shown in Fig. 7, a pendulum movement of a lever arm 70 via two auxiliary shafts 71, 72 and two freewheel gears 73, 74 and an idler gear 75 is converted into a same direction rotational movement. The two freewheel wheels 73, 74 transmit moments which are transmitted via the lever arm to a drive wheel 70a. The idler gear 75 serves to change direction. The two auxiliary shafts 71, 72 in addition to the freewheel gears 73, 74 still each have a fixed gear 76, 77. The fixedly mounted on the auxiliary shafts 71, 72 gears 76, 77 simultaneously engage a main gear 79, which on a main shaft 80th sitting.

The main shaft 80 can be connected to the carrying system in two ways:

Direct Connection: The main shaft 80 corresponds to the shaft 6 in FIG. 3.

Indirect connection: The rotational energy is first stored by the main shaft 80 in a flywheel. By means of a gear ratio, a part of the rotational energy is then transferred from the flywheel to the main axis 6 (FIG. 3).

According to Fig. 8, the lever arm is connected to the drive shaft via a hinge 90, which allows a second degree of freedom for the movement of the outer base body. As a result, wave movements from different directions can be taken up by the device for energy conversion and made usable.

The amount of rotational energy absorption depends on the relative movement of the outer base body to the inner base body. The resulting bearing forces, which act on the inner base body from the outer base body, are compensated by the inert mass and by the floating support of the inner base body. The mass of the inner base body including flywheel is designed accordingly. The mechanical energy that is absorbed by the direction-dependent rocking movement of the outer base body can thus be transferred to the conversion mechanism 9 shows a schematic representation of a further embodiment of a device for converting energy from an oscillatory movement into electrical energy. FIG. 9 shows, in particular, a schematic illustration of an embodiment of a conversion mechanism 91 for converting an oscillatory rocking movement of the outer base body 1 into a rotary movement of a conversion element about an axis of rotation, here about a main axis 6. The illustrated conversion mechanism 91 is pivotable about a suspension 92, executed, wherein the main axis 6 of the conversion mechanism 91 is formed substantially upright. Regardless of the inclination state or the inclination angle of the base body 1, during the oscillatory movement, the gravity G or the inertial mass of this "pendulum system" holds the conversion mechanism 91 essentially in the vertical (parallel to the gravitational force G) This is converted by means of the conversion mechanism 91 into a rotation / rotation of the conversion element about an axis of rotation (here about the main axis 6. The conversion mechanism 91 is formed with a push rod assembly 93 consisting of three push rods 94. The three push rods 94 The angle between the respective push rods is substantially 120 degrees (in the horizontal plane) Each push rod 93 is coupled to an associated rack 95. The respective rack 95 is disposed in a guide and in turn is associated with an associated one tooth wheel 96 in engagement, so that a forward or backward movement of the rack 95 is converted into a rotation of the gear 96. The gear 96 is connected via a shaft 97 with another gear 98. The gears 96, 98 always perform the same rotational movement. Furthermore, the gear 98 engages in a further gear 99, which couples to the conversion element which rotates about the main axis 6. By means of the illustrated mechanism, the oscillatory movement of the base body 1 is converted into a rotating movement of the gear wheel 99 or in a rotational movement of the conversion element about the main axis 6. The conversion element (for example a shaft) couples to a generator unit 100. In the generator unit 100, the energy of the rotary movement is converted into electrical energy. The generator unit 100 may be formed, for example, with at least one dynamo or a gyro generator. The rotational energy of the rotary motion can additionally in a rotational energy storage / flywheel / momentum storage (torque storage) 101 are stored. The rotational energy storage (torque storage) 101 may, for example, be a heavy mass disc or alternatively a plate on which one or more gyros are arranged (not shown).

Fig. 10 shows a schematic representation of the further embodiment of Fig. 9 from above. Gravity G acts vertically in the image plane. The illustrated conversion mechanism 91 is formed with a push rod assembly 93 consisting of three push rods 94. The individual push rods are arranged in a star shape in the horizontal plane (here image plane) at an angle of substantially 120 ° degrees. The push rods 93 are each coupled to an associated rack 95. Alternatively, the push rods 93 may also couple to a hydraulic piston (not shown). Each rack 95 is in turn engaged with a gear 96, so that a forward or backward movement of the rack 95 is converted into a rotation of the associated gear 96. The gear 96 is connected via a shaft with another gear 98. The gears 96, 98 always perform the same rotational movement. Furthermore, the respective gears 98 engage in a further gear 99. The further gear 99 in turn couples to the conversion element, so that the conversion element performs a rotational movement about the main axis 6.

The oscillatory movement is caused by a wave motion of a water surface 2. In Fig. 11, the device is shown in two different positions. The device is formed with a conversion mechanism 91, wherein the conversion mechanism 91 is configured to convert the oscillatory movement of the base body 1 into a rotational movement of a conversion element about an axis of rotation. The conversion mechanism 91 is pivotally mounted on a suspension point 92 (pivot point) on the ceiling of the base body 1. Regardless of the inclination state or of the inclination angle α of the base body 1, during the oscillatory movement, the main axis 6 of the conversion mechanism is substantially perpendicular, ie parallel to Gravity G. The conversion mechanism 91 is formed with a hydraulic piston assembly 93a consisting of three hydraulic pistons 94a. The hydraulic pistons 94a are each arranged in a star shape at an angle of 120 ° degrees (three-star arrangement). As a result, the oscillatory movement of the base body 1 is divided into three components of movement, wherein in each case a hydraulic piston receives a movement component. By means of a hydraulic motor (not shown) a rotational movement of a conversion element about a rotation axis (in this case the main axis) is effected. Also, the device may additionally be formed with a stabilizing gyroscope. In the generator unit, the energy of the rotational movement of the conversion element about the axis of rotation (here main axis) can then be converted into electrical energy.

Fig. 12 shows a schematic representation of another embodiment of a device for converting potential energy from an oscillatory movement into electrical energy. The oscillatory movement is caused, for example, by a wave motion of a water surface 2. In Fig. 12, the device is shown in two different height positions. The device is formed with a conversion mechanism (not shown) and a further conversion mechanism 121, wherein the further conversion mechanism is configured to convert a vertical movement (height movement or lifting movement) of the base body 1 into a rotational movement of another conversion element about a further rotation axis 125. The further conversion mechanism is pivotally mounted about a further suspension point 122 (pivot point) by means of a ball joint. The further suspension point 122 is arranged at the bottom of the base body 1. At the other suspension point 122 couples one end of a rigid arm 123 (Momentarm). The other end of the rigid arm 123 is fixed by means of a hinge at a fixed suspension point 124, so that the base body 1, during the oscillatory movement, moves in a circular path. Depending on the inclination angle ß of the rigid arm 123, the device or the base body 1 moves up and down (lifting movement along the circular path). The potential energy from this lifting movement of the base body 1 is converted into electrical energy by means of the further conversion mechanism 121 and a generator unit and / or a further generator unit. The features of the invention disclosed in the foregoing description, in the claims and in the drawing may be of importance both individually and in any combination for the realization of the invention in its various embodiments.
