[0002] Positioning device, positioning system and positioning arrangement for aligning at least one solar module carrier

[0003] The present disclosure relates to a positioning device, a positioning system and a positioning arrangement for aligning at least one solar module carrier in a plurality of predetermined spatial positions.

[0004] Solar modules, also called photovoltaic modules, convert solar radiation into electrical energy. For optimal use, solar modules are tracked to follow the sun, maximizing the amount of incoming radiation and thus the electrical energy generated. This is achieved by mounting solar modules on a mounting frame, which is attached to a positioning device driven by a shaft. This allows the solar modules to change their orientation and ensure perpendicular sunlight is directed onto the modules, regardless of the sun's position.

[0005] Due to their outdoor use, solar modules and positioning systems are frequently subjected to disruptive forces. These forces can be caused, for example, by wind or precipitation. When such forces act on the solar module and its positioning system, the module's orientation can be undesirably altered, leading to a loss of generated solar energy. Furthermore, these forces can induce unwanted vibrations in the solar modules and / or positioning systems, potentially causing damage. Particularly critical are excitations at the natural frequency of the positioning system with the mounted solar module carrier and module. Such excitation can lead to resonance, significantly increasing the vibration amplitude, which can result in higher stress on the positioning system and ultimately damage.

[0006] To counteract these disruptive forces, and in particular the excitation of vibrations, known positioning devices for solar modules incorporate damping systems that dampen unwanted movement of the solar modules. Such damping systems typically have many components and are therefore comparatively complex, which increases the cost of the corresponding positioning devices. Furthermore, these damping systems SUNOTEC Mounting Systems GmbH - 2 - 30A-165439

[0007] They require regular maintenance, for example, to change operating fluids. Furthermore, as a system's complexity increases, so does its susceptibility to malfunctions. Maintenance and troubleshooting also increase operating costs, require trained maintenance personnel, and, if not performed correctly, can lead to damage or total failure of the positioning equipment and / or the solar modules mounted on it.

[0008] There is a need for an improved positioning system. This system should overcome the problems mentioned above, as well as others, and in particular enable the safe and reliable alignment of solar modules, while also requiring little maintenance and exhibiting low complexity.

[0009] According to a first aspect of the invention, a positioning device is provided for aligning a solar module carrier in a plurality of predetermined spatial orientations. The positioning device comprises an adjusting arc provided with recesses, which is designed to be coupled to the solar module carrier in such a way that the adjusting arc and the solar module carrier can be rotated together about a rotational axis and that each of the plurality of predetermined spatial orientations of the solar module carrier is assigned exactly one predetermined rotational position of the adjusting arc.

[0010] Solar module support structures are also known as frame assemblies and are designed for mounting solar modules. The coupling between the solar module support structure and the frame assembly is a simple process.

[0011] The frame assembly and the positioning arch can be connected, for example, by a force-fit, material-fit, or form-fit connection. In particular, the solar module support can be screwed or otherwise fixed to the positioning arch. The positioning arch is designed to connect to a frame assembly or a solar module support. If, for example, a screw connection is provided between the positioning arch and the frame assembly, the frame assembly and the positioning arch can have corresponding recesses for screw connection. If the connection between the two elements is material-fit, e.g., by welding, the solar module support and the positioning arch should be made of weldable material in the area of ​​the weld. The positioning device serves to align the solar module support in a variety of predetermined spatial positions.Each spatial position can result in a different orientation of the solar module carrier in relation to a direction of gravity. SUNOTEC Mounting Systems GmbH - 3 - 30A-165439.

[0012] This corresponds to the spatial orientation of the solar module support. For example, the spatial orientation of the solar module support can be defined by a first angle around the axis of rotation between a vertical line on a ground / substrate and a surface of the frame arrangement intended for receiving solar modules.

[0013] The positioning arc can describe a segment of a circular arc, e.g., a segment extending from 90° to 180°, preferably from 120° to 180°, and is rotatable between predetermined rotational positions. The positioning arc and a solar module support coupled to it are rotatable together about the axis of rotation. In other words, the coupling of both components causes the solar module support to rotate in the same direction when the positioning arc rotates in a first direction. The movement of both elements occurs about the common axis of rotation, which can be defined by a common suspension, a common mandrel, a common pin, or a common shaft. Thus, there can be a fixed relationship between the spatial orientation of the solar module support and the rotational position of the positioning arc.The rotational position of the mounting bracket can be defined, for example, by a second angle around the axis of rotation between a vertical line on the ground and a side face of the mounting bracket. The second angle and the first angle can be identical or have a constant angular offset. For instance, the solar module support can be positioned in a spatial orientation where the first angle corresponds to 90°, meaning the solar module support forms a right angle with the vertical line, while the mounting bracket coupled to the solar module support can be positioned in a rotational orientation where the second angle is less than 90°.

[0014] The positioning device comprises a drive element rotatably mounted about a drive axis, with at least one engagement section. The engagement section is designed to engage in one of the recesses of the positioning arc when the drive element rotates about the drive axis, thus rotating the positioning arc about the axis of rotation.

[0015] The drive element is specifically designed to transmit a driving force to the adjusting arc. In particular, the drive element is driven and then transmits its own movement to the adjusting arc. The drive axis here refers to the (e.g., only) axis around which the drive element can be driven or rotated, for example, by a motor. To transmit a rotation of the drive element to the adjusting arc, the drive element has the following characteristics: SUNOTEC Mounting Systems GmbH - 4 - 30A-165439

[0016] at least one engagement section is present. When an engagement section of the drive element engages in a recess of the positioning arc, an interaction occurs between the engagement section and the recess, creating a force-fit connection between the positioning arc and the drive element. This allows the positioning arc to be set into rotation by the drive element. Thus, rotation of the drive element enables rotation of the positioning arc, allowing it to be moved into one of the predetermined rotational positions. As a result of rotation of the drive element, a solar module carrier coupled to the positioning arc can be moved from a first spatial orientation, corresponding to a first rotational position of the positioning arc, to a second spatial orientation, corresponding to a second rotational position of the positioning arc.The drive element thus enables a change between the individual rotation positions and therefore a rotation of a solar module carrier coupled to the positioning arch between different spatial orientations. In this way, solar modules, when mounted on a solar module carrier coupled to the positioning arch, can be tracked to follow the sun.

[0017] The positioning device comprises a locking element movably arranged relative to the drive element. The locking element is movable between a locking position and a release position, wherein in the locking position the positioning arc is fixed in one of the rotation positions and in the release position it releases the positioning arc for rotation about the axis of rotation. The positioning device is designed such that a rotation of the drive element causes the locking element to move from the release position to the locking position and / or from the locking position to the release position.

[0018] The locking element is specifically designed to lock the adjusting arm when it is in one of the predetermined rotation positions. The locking element is therefore designed to prevent, at least temporarily, further rotation of the adjusting arm around its axis of rotation into the next rotation position, namely when the locking element is in its locking position. In other words, the adjusting arm can only continue to rotate around its axis of rotation when the locking element is not in its locking position. Further rotation within the range of mechanical play may still be possible, although this is significantly less (e.g., by a factor of 10 or more) than rotation to the next rotation position. This prevents unwanted rotation of the adjusting arm. SUNOTEC Mounting Systems GmbH - 5 - 30A-165439

[0019] This ensures that even external disturbances, such as wind, do not cause a change in the spatial orientation of a solar module carrier coupled to the positioning arch. Since unwanted rotation of the positioning arch is prevented, unwanted vibration excitation is also avoided. The physical separation of the locking element and the drive element improves the reliability of the positioning device. This design also allows the locking element to rotate independently of the drive element. Thus, the rotational movement of the drive element can induce movement of the locking element, although this movement may occur in a different direction or plane than the rotational movement of the drive element itself.

[0020] The positioning device can be designed such that the drive element remains rotatable about the drive axis when the locking element is in the locking position. The possibility of movement of the drive element is then independent of whether the locking element is in the locking position or not. Thus, it is possible that the locking position only prevents unintended rotations of the positioning arc, e.g., due to external forces such as wind, but not an intended rotation of the drive element.

[0021] The drive element can be assigned at least one predetermined first angle of rotation or range of angles of rotation relative to the drive axis, wherein the positioning device is designed such that the locking element is only in the locking position when the drive element is aligned within one of the at least one predetermined first angle of rotation or range of angles of rotation. This is particularly the case when the drive element is aligned such that a part of the drive element located at the first angle of rotation or range of angles of rotation is closest to a fixed reference point and / or the positioning arc and / or the axis of rotation and / or the substrate. For example, none of the at least one engagement section engages in a recess of the positioning arc when the drive element is aligned within one of the at least one predetermined first angle of rotation or range of angles of rotation.The first rotation angle or range of rotation refers to a rotation around the drive axis. Therefore, if the drive element rotates around the drive axis, the locking element only assumes the locking position at one or more predetermined first rotation angles or ranges of rotation of the drive element and prevents unwanted further rotation of the adjusting arc into another rotation position at these first rotation angles or ranges of rotation. SUNOTEC Mounting Systems GmbH - ß - 30A-165439.

[0022] external disruptive forces. For example, initial rotation angles of 0°, 90°, 180° and 270° can be provided, and / or initial rotation angle ranges of 355°-5°, 85°-95°, 175°-185° and 265°-275° can be provided.

[0023] In a first variant, the drive element is assigned exactly one predetermined initial rotation angle or range of rotation angles, such that the locking element assumes the locking position exactly once during each complete rotation of the drive element around the drive axis, i.e., during each 360° rotation of the drive element around the drive axis. In this way, a periodic movement of the locking element into the locking position is ensured at a constant rotational speed of the drive element, with each period corresponding to a full rotation of the drive element.

[0024] In an alternative variant, the drive element is assigned several predetermined first rotation angles or rotation angle ranges, so that the blocking element assumes the blocking position several times during each complete rotation of the drive element around the drive axis, i.e., during each 360° rotation of the drive element around the drive axis.

[0025] It can be said that a suitable design of the first rotation angles or rotation angle ranges makes it possible to provide a desired period, frequency, and total number of locking positions per 360° rotation of the drive element. For example, the first rotation angle or rotation angle range can be designed so that the locking element assumes the locking position every 90°, i.e., 4 times per revolution of the drive element around the drive axis, thereby preventing unwanted further rotation of the actuator due to external disturbances.

[0026] If the drive element of the positioning device is assigned several predetermined first rotation angles or rotation angle ranges, adjacent first rotation angles or rotation angle ranges can be spaced apart from each other by a uniform rotation angle offset of the drive element around the drive axis. For example, the first rotation angles or rotation angle ranges can be evenly distributed over 360°. In this way, at a constant rotational speed of the drive element, a multiple periodic movement of the locking element into the locking position is provided during each complete revolution of the drive element, whereby the SUNOTEC Mounting Systems GmbH - 7 - 30A-165439

[0027] The number of periods per complete revolution of the drive element corresponds to the number of predetermined first rotation angles or rotation angle ranges.

[0028] The drive element can be assigned at least one predetermined second angle of rotation or range of rotation relative to the drive axis. The positioning device can be designed such that the locking element is only in the release position when the drive element is aligned within one of the at least one predetermined second angle of rotation or range of rotation. This is particularly the case when the drive element is aligned such that a portion of the drive element located at the second angle of rotation or range of rotation is closest to a fixed reference point and / or the positioning arc and / or the axis of rotation and / or the substrate. For example, one or more of the engagement sections will engage in one or more of the recesses of the positioning arc when the drive element is aligned within one of the at least one predetermined second angle of rotation or range of rotation.Therefore, if the drive element rotates around its axis of rotation, the locking element only assumes the release position at the second rotation angle(s) or range(s) of rotation. For example, the second rotation angle(s) can be 45°, 135°, 225°, and 315°, and / or the second rotation angle ranges can be 40°–50°, 130°–140°, 220°–230°, and 310°–320°.

[0029] The drive element can be assigned exactly one predetermined second rotation angle or range of rotation angles, such that the locking element assumes the release position exactly once during each complete rotation of the drive element around the drive axis, i.e., during each 360° rotation of the drive element around the drive axis. In this way, a periodic movement of the locking element into the release position is ensured at a constant rotational speed of the drive element, with each period corresponding to a full rotation of the drive element.

[0030] Alternatively, the drive element can be assigned several predetermined second rotation angles or rotation angle ranges, so that the locking element assumes the release position several times with each complete rotation of the drive element around the drive axis, i.e., with each 360° rotation of the drive element around the drive axis. SUNOTEC Mounting Systems GmbH - 8 - 30A-165439

[0031] By appropriately designing the second rotation angle or range of rotation angles, it is possible to provide a desired period, frequency, and total number of release positions per 360° rotation of the drive element. For example, the second rotation angle or range of rotation angles can be configured so that the locking element reaches the release position every 90°, i.e., 4 times per revolution of the drive element, thus enabling further rotation of the actuating arc 4 times per revolution of the drive element.

[0032] If the drive element is assigned several predetermined second rotation angles or rotation angle ranges, adjacent second rotation angles or rotation angle ranges can be spaced apart from each other by a uniform rotation angle offset of the drive element around the drive axis. For example, the second rotation angles or rotation angle ranges can be evenly distributed over 360°. In this way, at a constant rotational speed of the drive element, multiple periodic movements of the locking element into the release position are ensured during each complete revolution of the drive element, with the number of periods per complete revolution of the drive element corresponding to the number of predetermined second rotation angles or rotation angle ranges.

[0033] Each first rotation angle or range of rotation angles can be adjacent to or connected to a second rotation angle or range of rotation angles. This ensures, in particular, that the locking element moves back and forth between the locked and unlocked positions while the drive element rotates around the drive axis.

[0034] For example, the locking element is directly coupled to the drive element. The drive element can be designed, in particular, for direct contact with the locking element to exert a force on the locking element, which moves the locking element from the release position to the locking position and / or from the locking position to the release position. The locking element can have a holding section, and the drive element can have a guide section, wherein the holding section and the guide section interact such that, when the drive element rotates about the drive axis, the movement of the locking element from the release position to the locking position and / or the movement of the locking element from the locking position to the release position is effected. The holding section and the guide section can interact by direct contact. SUNOTEC Mounting Systems GmbH - 9 - 30A-165439

[0035] The holding section can be guided by the guide section as the drive element rotates. The guide section can define a guide curve for the holding section, so that the holding section moves along the guide curve as the drive element rotates. In other words, the guide curve defines the position of the holding section depending on the rotational position of the drive element. In particular, the guide curve can be designed to ensure periodic movement of the holding section during a constant rotation of the drive element.

[0036] The guide curve can be based on the total number of engagement sections of the drive element, the geometry of the engagement sections of the drive element, the geometry of the locking element, the geometry of the recesses of the actuator bow into which the locking element can engage, the first rotation angles or ranges of rotation, and / or the second rotation angles or ranges of rotation. The guide curve can define at which rotational position of the drive element the locking element is in the locked or released position. In other words, the design of the guide curve can determine at which rotational positions of the drive element the actuator bow can be moved by external forces, such as wind, and when such movement is blocked by the locking element.

[0037] The distance between the guide curve and the drive shaft can vary along the guide curve. A section of the guide curve with a varying distance to the drive shaft can induce movement of the locking element. Conversely, a section of the guide curve with a constant distance to the drive shaft can leave the position of the locking element unchanged and, in particular, not move the locking element. The guide curve can have at least one first section with a first distance to the drive shaft, and at least one second section with a different (e.g., larger or smaller) second distance to the drive shaft. Each of the at least one first section can be located at or within one of the first angles of rotation. Each of the at least one second section can be located at or within one of the second angles of rotation.

[0038] The guide curve can run in a plane perpendicular to the drive axis. In this case, the guide curve can be two-dimensional. SUNOTEC Mounting Systems GmbH - 10 - 30A-165439

[0039] For example, the distance between the guide cam and the drive shaft along the guide cam. For example, the guide cam is mirror-symmetric. The guide cam can have a single axis of symmetry. The guide cam can be composed of a multitude of mirror-symmetric sections. A number of the mirror-symmetric sections of the guide cam can correspond to a number of the first or second sections of the guide cam and / or a number of the first or second rotation angles or rotation angle ranges of the drive element. In particular, the guide cam is non-circular, can be substantially oval, and in one example is an ellipse.

[0040] The guide curve can oscillate axially relative to the drive axis. The guide curve does not lie in a plane perpendicular to the drive axis, but rather intersects such a plane. It can oscillate between two parallel planes, each perpendicular to the drive axis. Alternatively or additionally, the guide curve can lie on the surface of a virtual cylinder, which, for example, extends around the drive axis. Such a guide curve configuration is particularly suitable when the locking element is intended to move axially relative to the drive axis.

[0041] The drive element can have two axial end faces relative to the drive axis, and the guide section can be provided on at least one of the end faces or between the two end faces. The drive element can have a cylindrical section, on the circumferential surface of which the guide section can be provided. An axis of the cylindrical section preferably lies on the drive axis.

[0042] The guide curve can be continuous and / or smooth (e.g., relative to the drive axis in the circumferential direction), meaning it has no corners or interruptions. This prevents sudden changes in the movement of the locking element and minimizes wear on the guide and retaining elements. It also prevents the locking element from jamming unintentionally.

[0043] The guide section can be designed as a recess, in particular a groove or depression, or as a protrusion, in particular a rail or projection. If the guide section is designed as a recess, the holding section of the SUNOTEC Mounting Systems GmbH - 11 - 30A-165439

[0044] The blocking element should be provided as a complementary protrusion, and vice versa. This ensures reliable interaction between the guide section and the holding section.

[0045] The positioning device can be designed such that the movement of the locking element from the locking position to the release position and / or the movement of the locking element from the release position to the locking position is a linear movement, radial or axial with respect to the axis of rotation. Axial movements are those that run parallel to the axis of rotation, and radial movements are those that run radially away from or towards the axis of rotation.

[0046] The positioning device can include a linear bearing. The linear bearing is fixed relative to the axis of rotation and / or the drive axis and supports the locking element in a linearly movable manner. In other words, the linear bearing prevents movement of the locking element in spatial directions other than those defined by the linear bearing. For example, the linear bearing may only allow movement of the locking element in the radial direction relative to the drive axis and prevent any other movement of the locking element.

[0047] In some embodiments, the positioning device can be designed such that at least a portion of the locking element moves along a circular path when the locking element moves from the locking position to the release position and / or when the locking element moves from the release position to the locking position. This portion of the locking element can be the holding section or a locking section of the locking element. The circular path can lie in a plane with the axis of rotation or in a plane parallel to the axis of rotation. Alternatively or additionally, the circular path can lie in a plane with the drive axis or in a plane parallel to the drive axis. Alternatively, it is conceivable that the circular path lies in a plane that is inclined, in particular perpendicular to the drive axis and / or the axis of rotation.To enable the locking element to perform such a movement, it can be pivoted about a pivot axis. The movement of this part of the locking element relative to the axis of rotation and / or the drive axis has both a radial and an axial component. SUNOTEC Mounting Systems GmbH - 12 - 30A-165439.

[0048] The positioning device can include a rotary bearing fixed relative to the axis of rotation and / or the drive axis. This rotary bearing supports the locking element in such a way that it can pivot about a center point of the circular path and / or about the pivot axis. In other words, the rotary bearing prevents movement of the locking element in spatial directions other than those defined by the rotary bearing. For example, the rotary bearing may allow movement of the locking element only along the circular path and prevent movement out of the plane of the circular path.

[0049] The positioning device can be designed such that, particularly when the drive element is stationary, {a} at least in the locked position a force acts on the locking element that pushes the locking element towards the release position, or {b} at least in the release position a force acts on the locking element that pushes the locking element towards the locked position. This design applies in particular to the case where at least one of the movements of the locking element, i.e., the movement from the release position to the locked position and / or the movement from the locked position to the released position, is assisted by a force acting on the locking element or even exclusively induced by such a force. Such a force can be provided, for example, by a spring element, gravity, or an actuator.The force can therefore correspond to the weight force acting on the locking element, or to a spring force acting on the locking element. The locking element can be pre-tensioned, particularly in the direction of the locking position, for example by means of the spring force.

[0050] The positioning device can be designed such that a rotation of the drive element by a predetermined angular offset causes the locking element to move in the opposite direction to this force. For example, rotating the drive element by the predetermined angular offset causes the locking element, pre-tensioned in the direction of the locking position, to move towards the release position. The predetermined angular offset can correspond to an angular offset between the first predetermined angle or range of rotation and an adjacent angle or range of rotation of the second predetermined angle or range. The predetermined angular offset can separate the first section of the guide curve from the second section of the guide curve. SUNOTEC Mounting Systems GmbH - 13 - 30A-165439

[0051] One, several, or each of the engagement sections of the drive element can be configured as a finger or tooth. The respective engagement section can extend radially with respect to the drive axis. The respective engagement section can be formed as a projection that extends radially outward from a central (e.g., essentially cylindrical) section of the drive element. Each engagement section can, for example, be configured as a tooth of an involute gear or a pinion gear.

[0052] For example, the drive element has exactly one engagement section, i.e., only a single engagement section and not several engagement sections designed to engage in one of the recesses of the actuating arc when the drive element rotates around the drive axis. Alternatively, the drive element can have several engagement sections. In this case, the engagement sections can be arranged circumferentially around the drive axis. The engagement sections can be arranged in several groups. This means that the engagement sections of each group are closer together circumferentially than one or more adjacent engagement sections and / or closer together circumferentially than the groups of engagement sections are to each other. Each group can be assigned to one of the two rotation angles or rotation angle ranges.In other words, the engagement sections of a group can be arranged at one and the same second angle of rotation or range of angles of rotation, such that at least one of the engagement sections of this group is engaged with one of the recesses of the adjusting arc while the blocking element is in the release position. The second range of angles of rotation can correspond to an angular range over which the engagement sections of a group are distributed.

[0053] If the positioning device has several groups, an area lying between adjacent groups can be free of engagement sections. Each of these areas can be assigned to one of the first rotation angles or rotation angle ranges. For example, each area of ​​the drive element that is free of engagement sections extends over one of the first rotation angle ranges. When the drive element rotates about the drive axis, the locking element preferably remains in the locking position as long as there is no engagement between an engagement element of the drive element and a recess of the adjusting arc. As long as no engagement element of the drive element is in engagement with a recess of the adjusting arc, the adjusting arc cannot be moved by the drive element. SUNOTEC Mounting Systems GmbH - 14 - 30A-165439

[0054] rotate. In this case, the drive element must first be rotated further around the area that is free of engagement sections until at least one engagement element of the drive element engages in a recess of the adjusting arc and can effect a desired movement of the adjusting arc.

[0055] The engagement sections can be arranged and designed such that, during rotation of the drive element around the drive axis, they successively engage at least some of the recesses of the adjusting arc. These recesses can be spaced apart circumferentially around the axis of rotation and / or adjacent to each other. It is also conceivable that at least some of the engagement sections engage simultaneously in recesses (e.g., recesses spaced axially apart with respect to the axis of rotation).

[0056] The blocking element can include a blocking section. The blocking section is designed to engage in one of the recesses of the adjusting bow when the blocking element is in the blocking position. The blocking section of the blocking element establishes a force-fit or positive-locking connection with the adjusting bow to prevent rotation of the adjusting bow.

[0057] The recesses of the adjusting arc can comprise first and second recesses, wherein the at least one engagement section of the drive element engages in at least one of the first recesses of the adjusting arc when the drive element is rotated about the drive axis, and wherein the blocking section of the blocking element engages in one of the second recesses of the adjusting arc when the blocking element is in the blocking position.

[0058] The first and / or second recesses can each be designed as a recess extending along the axis of rotation or as a through hole extending along the axis of rotation. Through holes are defined as recesses that extend from one side of the mounting bracket along a hole axis to the opposite side of the mounting bracket, are enclosed radially by the mounting bracket to the hole axis, and are accessible from both sides of the mounting bracket. Recesses are defined as recesses that extend into the mounting bracket from one side and are accessible only from that side. The first and / or second recesses can be incorporated into an end face of the mounting bracket. For example, the end faces of the mounting bracket are (e.g., flat) [SUNOTEC Mounting Systems GmbH - 15 - 30A-165439]

[0059] to understand the surfaces of the arch that are spaced apart from the axis of rotation and, in particular, perpendicular to it.

[0060] Each of the second recesses can be assigned to one of the predetermined rotation positions. The second recesses and / or the first recesses can be located on a radial inside or a radial outside of the adjusting arc. The radial inside of the adjusting arc is located further radially inward than the radial outside of the adjusting arc with respect to the axis of rotation. The radial inside and the radial outside of the adjusting arc can define the inner and outer radii of the adjusting arc with respect to the axis of rotation. The second recesses and / or the first recesses can form an internal and / or external toothing of the adjusting arc, or a portion thereof. The internal toothing can be, for example, an involute toothing or a pinion toothing. The external toothing can be, for example, an involute toothing or a pinion toothing.In these cases, the corresponding recess can be a gap in the internal or external teeth.

[0061] It is therefore conceivable that each first recess is part of a radial internal toothing of the adjusting arc and that each second recess is part of a radial external toothing of the adjusting arc, or vice versa. Alternatively, it is conceivable that both the first and second recesses are part of an internal toothing of the adjusting arc, or that both the first and second recesses are part of an external toothing of the adjusting arc. As a further variant, it is conceivable that only the first recesses are part of an internal or external toothing, while the second recesses are each designed as cutouts or through holes extending along the axis of rotation, or vice versa.

[0062] The total number of first recesses can differ from the total number of second recesses. In particular, the total number of first recesses can be greater than the total number of second recesses. For example, the positioning device can be designed such that, during rotation of the drive element around the drive axis, several engagements of engagement sections into first recesses occur successively before the locking section of the locking element engages in one of the second recesses. A ratio of the total number of first recesses to the total number of SUNOTEC Mounting Systems GmbH - 16 - 30A-165439

[0063] The number of second recesses can correspond to (i) a ratio of the total number of second rotation angles or rotation angle ranges to the total number of first rotation angles or rotation angle ranges, (ii) a total number of engagement sections of the drive element, or (iii) a number of engagement sections per group of engagement sections of the drive element. For example, 100 first recesses and 25 second recesses are provided, wherein the drive element has four engagement sections that are assigned to the same first rotation angle range.

[0064] The first set of recesses can be shaped differently from the second set of recesses. For example, the geometry (e.g., cross-section or longitudinal section) of the first set of recesses can differ from that of the second set of recesses. For instance, the first set of recesses might be designed as gaps in an involute or pinion gear, while the second set of recesses, viewed from above along the axis of rotation, might have a rectangular or square cross-section, at least in some sections. This allows the first and second set of recesses to be adapted to the shape of the engagement section and the locking section, respectively, to ensure reliable engagement. While the tooth geometries of an involute or pinion gear ensure good rotational transmission with low wear, a square cross-section of the second set of recesses can provide a reliable locking effect.

[0065] The first and / or second recesses can each have a circular segment-shaped contour in a top view along the axis of rotation. For example, contours can be provided that correspond to a circular segment smaller than a semicircle, thus extending, for example, over an angular range of 160° or 175°. It is possible that the individual circular segment-shaped contours merge into one another in the top view, i.e., that they are not separated from each other by areas of constant radius.

[0066] According to a second aspect of the invention, a positioning system for aligning a solar module carrier is provided. The positioning system comprises the positioning device according to the first aspect of the invention and the solar module carrier. The solar module carrier is coupled to the positioning arch in such a way that the positioning arch and the solar module carrier can be rotated together about the axis of rotation and that each of the plurality of predetermined SUNOTEC Mounting Systems GmbH - 17 - 30A-165439

[0067] Each spatial position of the solar module carrier is assigned exactly one of the predetermined rotation positions of the positioning arc.

[0068] The positioning system can also include the solar module, which is then connected to the solar module support structure. The solar module support structure can be made of metal beams. These metal beams can be made of weather-resistant stainless steel or more cost-effective corrosion-protected steel, but also of other coated and uncoated metals or alloys. The coupling between the solar module support structure and the solar module support structure is achieved through a flexible connection.

[0069] The frame assembly and the support arch can be connected via a force-fit, material-fit, or form-fit connection. In particular, the solar module support can be screwed or otherwise fixed to the support arch. By coupling the solar module support or the frame assembly to the support arch, a fixed angular relationship between the solar module support and the support arch can also be established, i.e., a fixed difference between the first angle and the second angle. In other words, an angular relationship between the rotational position of the support arch and the predetermined spatial positions of the solar module support can be ensured by appropriately coupling the two components.

[0070] The positioning system may further include a support element that carries the positioning device and is attached to or embedded in the substrate. The support element may consist of a single support pillar or of several support pillars connected together (e.g., in the shape of an "A"). The positioning device may be attached to the support element. The axis of rotation and / or the drive axis and / or the pivot axis may be defined relative to the support element. For example, the positioning system includes a first pivot bearing fixed to the support element, which defines the axis of rotation, and a second pivot bearing fixed to the support element, which defines the drive axis. The positioning arc may be rotatably attached to the support element about the first pivot bearing. The drive element may be rotatably attached to the support element about the second pivot bearing. The rotary or linear bearing of the locking element may also be fixed to the support element.

[0071] For example, the positioning system includes a drive shaft. The drive shaft can be rotatably mounted to the support element around the second rotary bearing. The drive shaft can be coupled to the positioning device in such a way that rotation of the drive shaft drives the drive element. Here, the coupling can be SUNOTEC Mounting Systems GmbH - 18 - 30A-165439

[0072] The connection between the drive shaft and the drive element can be direct or indirect. In other words, the drive shaft can either be directly connected to the drive element, or various components can be arranged between the drive shaft and the drive element to transmit rotation from the drive shaft to the drive element. The coupling between the drive shaft and the drive element can be achieved via a rigid connection. Examples of rigid connections include force-fit, material-fit, or form-fit connections. For instance, the drive shaft can be bolted to the drive element or welded to it. The drive shaft can be a single piece or comprise multiple sections. In particular, the drive shaft can consist of several drive shaft sections that are rigidly connected to one another.In this case, the drive shaft sections can be located in different planes and the drive element can be non-rotatably connected to one of the drive shaft sections that extends along the drive axis about which the drive element is rotatable.

[0073] The positioning system can include a motor for driving the drive shaft. The motor is specifically designed and arranged to drive the drive shaft. The motor can be an electric motor, particularly a DC motor. The motor can include a motor shaft driven by the motor, which is coupled to the drive shaft in a rotationally transmitting, and in particular rotationally fixed, manner, or it can drive the drive shaft directly. The positioning system can include a gearbox designed to translate a rotation of the motor shaft into a rotation of the drive shaft. In this case, the motor and gearbox together form a drive unit.

[0074] According to a third aspect of the invention, a positioning arrangement for aligning multiple solar module carriers is provided. The positioning arrangement comprises a first positioning device according to the first aspect of the invention or a first positioning system according to the second aspect of the invention. Furthermore, the positioning arrangement comprises at least one second positioning device according to the first aspect of the invention or at least one second positioning system according to the second aspect of the invention. Additionally, the positioning arrangement comprises a drive shaft (e.g., the drive shaft of the positioning system) that is coupled to several positioning devices of the positioning arrangement such that rotation of the drive shaft drives the drive elements of these positioning devices. The positioning arrangement particularly comprises a combination of several SUNOTEC Mounting Systems GmbH - 19 - 30A-165439

[0075] Positioning devices and / or positioning systems connected via a single drive shaft. This makes it possible to rotate many solar module carriers simultaneously around their respective (e.g., identical or different) axes of rotation using the same drive shaft. It is conceivable that the positioning arrangement includes a single motor to drive the drive shaft, which can then drive all the positioning devices or positioning systems of the arrangement via the drive shaft.

[0090] Figures 17a to 17b are side views of a section of the positioning device from Fig. 15.

[0091] Figure 1 shows a schematic representation of an exemplary positioning arrangement 1000 according to the present disclosure. The positioning arrangement 1000 comprises a first positioning system 800. The first positioning system 800 comprises a positioning device 100 and a solar module support 200, wherein the positioning device 100 is connected to the ground or substrate B via a support element 400 of the positioning system 800.

[0092] The first positioning system 800 is connected to at least one other positioning system 800, which is designed like the first positioning system 800, via a drive shaft 300. The drive shaft 300 can be manufactured in one piece, or it can comprise several drive shaft sections 310 that are coupled to each other for rotational transmission. The drive shaft sections 310 can be located in different planes. A separate drive shaft section 310 can be provided for each positioning system 800, running along a drive axis of that positioning system 800. The drive axes can differ between the positioning systems 800, i.e., be parallel, inclined, or skew to each other. This enables the positioning systems 800 to be driven by the drive shaft 300, even if the positioning systems 800 are installed on uneven ground.

[0093] Furthermore, the positioning arrangement 1000 comprises a drive 500 with a motor 510 and a gearbox 520 coupled to it, which is coupled to and drives the drive shaft 300. The motor 510 is specifically designed as an electric motor. The drive 500 is shown in dashed lines in Figure 1. SUNOTEC Mounting Systems GmbH - 21 - 30A-165439

[0094] Alternatively, it can be located on the other side, i.e., directly on the first positioning system 800, or between the positioning systems 800.

[0095] Figure 2 shows a schematic representation of the positioning system 800. The positioning system 800 comprises the positioning device 100, which is connected to the ground or the substrate B via the support element 400. Figure 2 shows that the solar module carrier 200, which supports a solar module 220, includes a frame assembly 210 that is connected to the positioning device 100. The frame assembly 210 is arranged on the positioning device 100 so that the solar module 220 is oriented upwards, i.e., in the direction of the incident sunlight. The orientation of the solar module carrier 200 is defined by its spatial orientation. This spatial orientation is defined, in particular, by a first angle α about the axis of rotation RA between a vertical spatial orientation axis RLA perpendicular to the ground B and a surface of the solar module 220 that can be mounted on the frame assembly.The spatial orientation of the solar module carrier 200 is determined by the rotational position of an adjusting arc 10 of the positioning device 100. This rotational position is defined by a second angle b about the rotational axis RA between the spatial orientation axis RLA and the adjusting arc 10. The angle difference c = b - a can be constant. The positioning device 100 can change the spatial orientation of the solar module carrier 200 by rotating the solar module carrier 200 about a rotational axis RA. The rotational axis RA is defined relative to the support element 400.

[0096] Figure 3 shows a frontal view of a positioning device 100 according to a first embodiment, and Figure 4 shows a detailed view of this positioning device 100. The positioning device 100 comprises an adjusting arc 10. The adjusting arc 10 is designed as an arc-shaped element which, in the example shown, describes a semicircle, i.e., spans an angle of 180°. However, angles other than 180° are also possible. The center of the arc-shaped element lies on the axis of rotation RA. With respect to the axis of rotation RA, the adjusting arc 10 has a radial outer surface 11 and a radial inner surface 13, which, in a top view along the axis of rotation RA, define two substantially parallel edges of the arc-shaped element. The adjusting arc 10 has a plurality of recesses 14, 16 spaced apart circumferentially around the axis of rotation RA.On the radial outer side 11, first recesses 14 are provided, forming an involute toothing; on the radial inner side 13, second recesses 16 are provided, which have circular segment-shaped contours. At the circular arc end of the adjusting arc is SUNOTEC Mounting Systems GmbH - 22 - 30A-165439.

[0097] A crossbeam 17 is provided which connects the two ends of the semicircular element and is designed for coupling to the frame arrangement 210.

[0098] The positioning device 100 comprises a drive element 20, which is rotatably mounted about a drive axis AA. This drive axis AA is fixed relative to the support element 400. The drive element 20 is, in particular, rotationally fixed to the drive shaft 300, i.e., for example, to the drive shaft section 310 associated with this positioning device 100. The drive element 20 has an engagement section 22 designed as an involute tooth, which extends away from the drive axis AA and is moved along a circular path about the drive axis AA when the drive element 20 rotates. The engagement section 22 engages in one of the first recesses 14 of the positioning arc whenever the drive element 20 is aligned at a first predetermined angle of rotation. Thus, the positioning arc 10 can be iteratively rotated about the axis of rotation RA by the drive element 20.

[0099] The positioning device 100 further comprises a locking element 30, which is mounted radially displaceable about the axis of rotation RA by a linear bearing 36. The positioning device 100 is designed such that the rotation of the drive element 20 about the drive axis AA causes the locking element 30 to move from a release position, in which the locking element 30 permits rotation of the adjusting arc 10, to a locking position, in which the locking element 30 engages with one of the second recesses 16, and likewise causes an opposite movement of the locking element 30. During continuous rotation of the drive element 20, the locking element 30 moves periodically up and down radially to the axis of rotation RA along a first direction of movement Bl. The locking element 30 is always in the locking position when the engagement section 22 is not engaged with a first recess 14.This prevents unwanted rotation of the adjusting arc 10 caused by disruptive forces. Furthermore, this blocking of the adjusting arc 10 by the blocking element 30 ensures that disruptive forces acting on the solar module carrier are not transmitted to the drive element 20 and thus to the drive shaft 300.

[0100] Figures 5 and 6 show a sectional view and a perspective rear view of the positioning device 100 according to the first embodiment. Figures 7a to 7f show the movement sequence of the positioning device 100 when the drive element 20 is rotated clockwise. The locking element 30 comprises SUNOTEC Mounting Systems GmbH - 23 - 30A-165439

[0101] Accordingly, a holding section 32 is directly coupled to the drive element 20 and guided by a guide section 24 of the drive element 20. The guide section 24 is formed as a groove in an axial end face 23 of the drive element 20 and defines a guide curve 25 that lies in a plane El orthogonal to the drive axis AA and dictates the movement of the holding section 32. The holding section 32 of the locking element 30 is designed as a cylindrical projection complementary to the groove and arranged in the groove. This holding section 32 of the linearly movable locking element 30 interacts with the guide section 24 of the rotatably mounted drive element 20 such that, when the drive element 20 rotates, it moves along the guide curve and is thereby displaced up and down along the first direction of movement Bl.The guide curve 25 has a non-circular, essentially oval shape, with different sections 27, 29 of the guide curve 25 having different distances Al, A2 to the drive axis AA. When the drive element 20 rotates about the drive axis AA, the holding section 32 moves along the first direction of movement Bl due to the variation in the distances Al, A2. Section 29 is assigned to a first rotation angle range 33 of 180°, whereby the locking element 30 is in the locking position when the drive element 20 is aligned within this rotation angle range, i.e., when section 29 is oriented upwards and / or is closest to the rotation axis RA.Section 27 is assigned to a second rotation angle 31, whereby the locking element 30 is in the release position when the drive element 20 is aligned in this rotation angle 31, i.e. when the section 27 of the drive element 20 located at this rotation angle 31 is oriented upwards and / or is closest to the rotation axis RA.

[0102] In Fig. 7a, the drive element is aligned in the first rotation angle range 33, so that the locking element 30 is in the locking position and engages in one of the second recesses 16. In the state according to Fig. 7b, the drive element 20 is also just aligned in the first rotation angle range 33, so the locking element 30 remains in the locking position. The guide curve 25 runs with a constant radius relative to the drive axis AA in the region of the second rotation angle range 33, so that the position of the locking element 30 is maintained. The distance between the guide curve 25 and the drive axis AA increases alongside the second rotation angle range 33 up to the first rotation angle 31. Thus, as soon as the drive element 20, starting from the state in Fig.7b is rotated further so that it is no longer aligned in the second rotation angle range 33, the holding section 32 of the blocking element 30 is moved upwards along the SUNOTEC Mounting Systems GmbH - 24 - 30A-165439.

[0103] The direction of movement Bl is shifted while the engagement section 22 moves into one of the first recesses 14. As soon as the locking element 30 has left the second recess 16, the adjusting arc 10 is further rotated about the axis of rotation RA by the engagement section 22 engaging in the first recess 14. In Fig. 7d, the drive element is aligned in the second rotation angle, the locking element 30 is in the release position, and the engagement section 22 is engaged with the first recess 14. As shown in Fig. 7e, the locking element 30 is then moved again towards the locking position, engaging in an adjacent second recess 16. During this movement, the engagement section 22 moves out of the first recess 14. In Fig. 7f, the drive element 20 is again aligned in the first rotation angle range 33, and the sequence then begins again from Fig. 7a.In this way, the adjusting arc can be rotated 10 times in succession, i.e., one second recess after the other, whereby, when the blocking position is present, neither a rotational transfer from the adjusting arc to the drive element nor a further rotation of the adjusting arc is possible due to the blocking element.

[0104] Figure 8 shows a second embodiment of the positioning device 100. In this case, the drive element 20 has not just one, but several engagement sections 22. In the example shown, a total of three engagement sections 22 are provided. The engagement sections 22 are not formed as part of an involute gear. Instead, the three engagement sections 22 represent individual projections that extend radially outwards from the drive element 20 with respect to the drive axis AA and are circularly rounded at one radially outer end. The engagement sections 22 can be formed as teeth of a pinion gear. The three engagement sections 22 together form a first group 28 of engagement sections 22.In other words, the three engagement sections 22 are grouped together such that the angular distance between the central engagement section 22 and the outer engagement sections 22 is significantly smaller than the angular distance between the outer engagement sections 22 and each other along the remaining circumference of the drive element 20. Apart from the three engagement sections 22 located in the second rotation angular range 35, the remaining circumference of the drive element 20, which also includes the first rotation angular range 33, is free of engagement sections. When the drive element 20 is aligned in the second rotation angular range 35, at least one of the engagement sections 22 engages with one of the first recesses 14. When the drive element is aligned in the first rotation angular range 33, the locking element 30 is in the locking position. SUNOTEC Mounting Systems GmbH - 25 - 30A-165439.

[0105] In this second embodiment, the second recesses 16 on the radial inner side of the adjusting arc 10 are spaced at a larger angular offset in the circumferential direction than the first recesses 14. The distance between adjacent second recesses 16 is such that the engagement sections 22 can successively engage three adjacent first recesses 14 and rotate the adjusting arc 10 further before the locking element 30 engages the next of the second recesses 16. Thus, the radial inner side of the adjusting arc 10 has fewer second recesses 16 than the radial outer side of the adjusting arc 10 has first recesses 14. In the example shown, three times as many first recesses 14 are provided as second recesses 16, since the group 28 consists of three engagement sections 22.

[0106] Figures 9 and 10 show a third embodiment of the positioning device 100, in which the drive element 20 has exactly two engagement sections 22, which together form a group 28. Here, twice as many first recesses 14 are provided as second recesses 16, since the group 28 consists of two engagement sections 22. Furthermore, the engagement sections 22 each have a substantially circular contour at their radially outer end and are designed as teeth forming a rack-and-pinion gear, which is complementary to the external gearing of the adjusting arc with the first recesses 14.

[0107] While the first recesses 14 in the first and second embodiments of the positioning device 100 are located next to each other and are separated from each other by arc sections with a uniform radius to the axis of rotation RA, this is not the case in the third embodiment. As shown in Fig. 9, the first recesses 14 are arranged here in groups, each group being designed to correspond to the group 28 of engagement sections 22. The first recesses 14 of each group are spaced apart by arc sections with a smaller radius than the recesses 14 of adjacent groups.

[0108] Figures 11 to 13 and Figures 14a and 14b show a fourth embodiment of the positioning device 100. In contrast to the first to third embodiments, the locking element 30 moves in a second direction of movement B2, which is not radial to the axis of rotation RA, but parallel to the axis of rotation RA. To ensure that a rotation of the drive element 20 about the drive axis AA causes a movement of the locking element 30 along the second direction of movement B2, the guide section 24 and the SUNOTEC Mounting Systems GmbH - 26 - 30A-165439

[0109] In the fourth embodiment, the guide curve 25 is designed differently than in the first to third embodiments. The guide curve 25 does not lie in the first plane El, but rather runs circumferentially around the drive axis AA at a constant distance from the drive axis AA, oscillating between the first plane El and a parallel second plane E2. The guide section 24 is formed as a groove in a substantially cylindrical outer circumferential wall 37 of a cylindrical section 39 of the drive element 20, so that the guide curve 25 lies, so to speak, in a cylindrical surface and runs axially up and down with respect to the drive axis AA. The distance traveled by the locking element 30 along the second direction of movement B2 between the locking and release positions corresponds to the distance A3 between the first plane El and the second plane E2.The locking section 34 engages not radially, but axially into one of the second recesses 16 when the locking element 30 is in the locking position. In this case, the bearing 37 ensures that the locking element can only move axially.

[0110] Figures 15 and 16, as well as Figures 17a and 17b, show a fifth embodiment of the positioning device 100. Here, the bearing 43 is a pivot bearing with a pivot axis SA fixed to the support element 400, about which the locking element 30 pivots when the drive element 20 rotates about the drive axis AA. Thus, the movement of the locking element 30 is not an axial or radial linear movement, but a pivoting movement. The locking section 34 moves along a circular path when the locking element 30 is moved from the release position to the locking position and vice versa, with the circular path extending around the pivot axis SA. In this example as well, the guide section 24 is formed as a groove in an outer circumferential surface 37 of the drive element 20, the groove extending axially up and down or back and forth with respect to the drive axis AA, and the retaining section 32 of the locking element 30 being guided in the groove.In the example shown, the second recesses 16 have a rectangular cross-section in plan view along the axis of rotation RA, while the blocking section 34 is essentially truncated pyramid-shaped.

[0111] The embodiments described with reference to the figures are not to be considered limiting. Thus, the features of the first to fifth embodiments can also be combined or substituted for one another. For example, the number and shape of the engagement sections 22, the number and shape of the recesses 14, 16, the direction of movement Bl, B2 of the locking element can be changed. SUNOTEC Mounting Systems GmbH - 27 - 30A-165439

[0112] 30 and the design of the guide section 24 and the guide curve 25 of the respective embodiments may be adapted. It is also conceivable to couple several of the positioning units described herein to one and the same solar module carrier or to provide several of the positioning units described herein per solar module carrier. Further modifications are also conceivable, for example, based on the features described for the individual aspects of the invention.
