Description

[0001] SWIVEL MODULE FOR SOLAR ENERGY GENERATION

[0002] Field of the invention

[0003] The invention relates to a pivoting module comprising at least one connecting flange body and a pivoting flange body, a system comprising the pivoting module according to the invention and a solar system comprising the system according to the invention.

[0004] Description of the invention

[0005] The subject matter of the invention is an overall unit, here referred to as a pivoting module, consisting, among other things, of two rotatably connected receiving bodies that can be rotated relative to one another via a gear unit. The receiving bodies have flange connections. A distinction is made between a receiving body, here referred to as a connecting flange body, which is mounted on a boom, and a pivoting flange body, which is rotatably mounted on the receiving flange body. The entire device serves to move solar collectors from the open state to the closed state and vice versa. In the open state, four collector units, each consisting of a collector and a holding arm, are arranged, for example, in a star shape. The pivoting module now makes it possible to close an inner collector pair with an outer collector pair. This is achieved by pivoting the outer collector pair through 180° from the open to the closed state.The inner collector pair comprises a first and a third energy module, which are fixedly attached to the connecting flange body. The outer collector pair comprises a second and a third energy module, which are mounted on the pivoting flange body.

[0006] One object of the invention is, in addition to the friction-locked assembly of the collector units, to connect the electrical cables and hydraulic lines from the boom and the support arms. Further objects of the invention will become apparent from the following explanations.

[0007] For the outer collectors, the pipes and electrical cables can be routed via a pivot axis according to the invention. In addition to the supply and return lines for the heat transfer medium, a line for the cleaning water flow is also provided. Here, too, a connection of the piping from the boom to the support arms of the inner collector pair is required. Mechanical stops should precisely specify the end positions, open and closed. Expansion compensators can compensate for the thermal expansion of the piping from the boom and the support arms. The piping in the pivoting module can be thermally insulated. Thermal bridges should be prevented. The entire mechanical system can be completely sealed, thus protecting against any harmful environmental influences.

[0008] A further objective is to create a compact delivery unit. This should minimize assembly work in the field and make incorrect assembly technically impossible (e.g., different plugs and terminal connections). When assembling the collector units, there is no distinction made between left, right, inner, or outer collector units. These are identical parts, and the flow direction will always be correct. The system is modular in its use. In the full version, cooled PV (photovoltaics) can be connected. This will primarily be for concentrating PV systems, although the heat should still be usable for industrial purposes or thermal power generation. All hydraulic and electrical cable feedthroughs are required in this case.Alternatively, purely thermal collectors can be used, preferably concentrator systems for high temperatures or for direct steam generation. The installation of electrical systems is not necessary here. Mixed operation is also conceivable, so that, for example, the outer collectors are uncooled PV panels, while the inner collectors are purely thermal energy generators. These systems are particularly easy to implement and are of interest for individual households, but less so for industrial use. Depending on the requirements, certain components can be omitted. With the full version, it is possible to switch from purely thermal heaters to hybrid systems with PV at an advanced stage of development.

[0009] Another aspect of modularity relates to the technical design. The idea is to use as many identical parts as possible, which condenses the parts list and consequently reduces development and manufacturing costs.

[0010] All the above criteria can be met, as can be seen from the following description and figures.

[0011] One object of the invention is achieved by a pivoting module comprising at least one connecting flange body and a pivoting flange body, wherein the connecting flange body comprises at least one fastening section with at least one first flange receptacle for receiving a boom of a solar system and a second flange receptacle for receiving a holding arm of a first energy module, such as a (mirror-concentrating) solar collector or a PV module, wherein the pivoting flange body comprises at least one fastening section with at least one third flange receptacle for receiving a holding arm of a second energy module, such as a (mirror-concentrating) solar collector or a PV module, wherein the pivoting flange body is rotatably mounted on the connecting flange body in order to transfer the second energy module from an operating position into a closed position,in which closed position the first energy module is closed by the second energy module.,

[0012] The rotatable mounting of the swivel flange body on the connecting flange body provides a particularly simple way to move the second energy module into the closed position. Furthermore, the rotatable mounting of the swivel flange body on the connecting flange body creates the prerequisite for establishing a simple and reliable connection of electrical and / or hydraulic lines of the boom, the first energy module, and / or the second energy module to electrical and / or hydraulic lines of the boom, the first energy module, and / or the second energy module.

[0013] It is preferably provided that the fastening section of the connection flange body comprises a fourth flange receptacle for receiving a holding arm of a third energy module, for example a (mirror-concentrating) solar collector or a PV module, and the fastening section of the pivoting flange body comprises a fifth flange receptacle for receiving a holding arm of a fourth energy module, for example a (mirror-concentrating) solar collector or a PV module, so that the fourth energy module can be transferred together with the second energy module from an operating position into a closed position, in which closed position the third energy module is closed by the fourth energy module.

[0014] This allows for a star-shaped arrangement of the energy modules in the operating position and a particularly space-saving, compact, and protected closed position. In particular, this preferred embodiment of the pivoting module according to the invention allows four energy modules to be attached to the boom of the solar system. The rotational movement of the pivoting flange body allows these four energy modules to be reduced to two compact units, each consisting of an inner energy module and an outer energy module. This outer energy module closes the inner energy module in the closed position.

[0015] It is preferably provided that the fastening section of the connecting flange body and / or the fastening section of the swivel flange body is / are designed in the shape of a spherical segment.

[0016] This gives the swivel module particularly high stability. Furthermore, the volume enclosed by the two ball segments provides an area for accommodating additional components, especially connectors, couplings, etc.

[0017] It is preferably provided that the fastening section of the connecting flange body, preferably the connecting flange body, and / or the fastening section of the pivoting flange body, preferably the pivoting flange body, is / are designed as a die-cast part or injection-molded part.

[0018] This simplifies the production of the swivel module and keeps the manufacturing costs of the swivel module according to the invention low. Furthermore, the structural integrity of the swivel module is increased.

[0019] Preferably, the fastening section of the connecting flange body, preferably the connecting flange body, and the fastening section of the swivel flange body, preferably the swivel flange body, are manufactured as identical parts or are identical parts in the raw production. This has the advantage that only one tool is required, which in turn reduces manufacturing costs.

[0020] It is preferably provided that the fastening section of the swivel flange body contacts the fastening section of the connecting flange body in the operating position of the second energy module, preferably at end stops.

[0021] In this preferred embodiment, the fastening sections of the connecting flange body and the pivoting flange body contact each other when the pivoting flange body (or the second and optionally also the fourth energy module) is in the operating position. This allows the pivoting flange body and the energy modules attached to it to be mounted particularly stably on the boom of the solar system in the operating state. Particularly when the fastening sections are spherical segment-shaped, the contact between the fastening sections—or more generally: between the pivoting flange body and the connecting flange body—enables particularly favorable force dissipation via the connecting flange body to the boom of the solar system. This increases the operational reliability of the solar system in which the pivoting module according to the invention is used.In addition to the operating position (open state), there can also be at least one other position in which the two flange bodies (i.e., the connecting flange body and the pivoting flange body) or their fastening sections contact each other. There can also be an additional end stop on the pivoting module that fixes the closed state (locked position), although this can also be achieved via the energy modules, for example, via the mirror ends of the collectors or the edges of the PV modules.

[0022] Even when the collectors are removed, an end stop should be present. As explained below, it can also be provided that the motors that drive the swivel movement detect that the gearbox is at its stop via the load sensor.

[0023] It is preferably provided that the first energy module and / or the second energy module and / or the third energy module and / or the fourth energy module is / are designed as a solar collector, in particular a thermal one.

[0024] The pivoting module proves particularly advantageous here, as the pivoting connection ensures particularly reliable protection of the sensitive components of the solar collectors in the closed position. In particular, the solar collectors can be protected from physical damage in this way.

[0025] It is preferably provided that the first energy module and / or the second energy module and / or the third energy module and / or the fourth energy module is designed as a photovoltaic module.

[0026] In connection with photovoltaic modules (PV modules), the swivel module also offers particularly reliable protection for sensitive components of the PV modules, which components remain exposed in conventional solar systems - even when the solar system is not in operation.

[0027] It is preferably provided that the first energy module and the third energy module are each formed by a solar collector, in particular a thermal one, and the second energy module and the fourth energy module are each formed by a photovoltaic module.

[0028] This combination of solar collectors (connected to the connecting flange body) and photovoltaic modules (connected to the pivoting flange body) enables a particularly compact and space-saving design of the solar system in the closed position, especially since the generally less space-consuming photovoltaic modules can serve as covers for the generally larger solar collectors. Preferably, the first energy module and the third energy module are each formed by a solar collector, in particular a thermal one, and the second energy module is formed by a cover for closing the first energy module, and the fourth energy module is formed by a cover for closing the third solar collector.

[0029] This deliberately compromises the functionality of the solar system equipped with the pivoting module in order to ensure the simplest and most reliable protection possible for the two energy modules attached to the connecting flange body. It also makes it possible to adapt the cover(s) specifically to the energy module being connected.

[0030] It is preferably provided that the connecting flange body and the swivel flange body are fluidically connected to one another via at least one rotary feedthrough.

[0031] The at least one rotary union enables the fluidic connection of the connecting flange body and the swivel flange body or their flange receptacles, and simultaneously allows the swivel flange body to be transferred into the closed position (or the rotational movement of the swivel flange body, which rotational movement transfers the second and, if applicable, the fourth energy module from the operating position to the closed position). This creates a particularly simple and reliable connection between the lines of the boom and the holding arms of the energy modules.

[0032] It is preferably provided that connection modules for hydraulic and / or electrical lines of the holding arms and / or the boom are provided at through-openings of the flange receptacles, wherein the connection modules are preferably designed such that the hydraulic and / or electrical lines can be inserted into the connection modules during assembly.

[0033] This allows for particularly simple installation of the support arms and / or the boom on the connecting flange body and / or the swivel flange body. Because the connecting modules are located directly on the flange mounts, the respective hydraulic and / or electrical connections can be made directly at the mounting sections of the connecting and swivel flange bodies, which are easily accessible from the outside, eliminating the need for laborious work inside the connecting and / or swivel flange bodies. This significantly simplifies handling of the swivel module—particularly during installation in a corresponding solar system.

[0034] It is preferably provided that the connection flange body and / or the swivel flange body comprises / comprises pipes for electrical cables in order to guide these cables to at least one terminal box of the swivel module.

[0035] In other words, the connecting flange body and / or the swivel flange body can have pipes that lead to at least one terminal box. This allows electrical cables, especially those of the support arms and / or the boom, to be routed to or into the terminal box in a particularly simple and reliable manner, without the need for complex cabling when mounting the swivel module to the boom or the support arms to the swivel module.

[0036] It is preferably provided that the connecting flange body and / or the swivel flange body has / have receptacles for adapters and / or retaining plates.

[0037] This makes it possible to accommodate a mechanical unit, such as a gear unit, that mediates relative movement between the connecting flange body and the swivel flange body in a particularly simple and compact manner with precise dimensions in or on the swivel module. This enables a simple and reliable transfer of the swivel flange body from the operating position (the position in which the second energy module is in the operating position) to the closed position (the position in which the second energy module is in the closed position).

[0038] It is preferably provided that the swivel module comprises at least one gear, which gear is preferably arranged between a first holding plate connected to the connecting flange body and a second holding plate connected to the swivel flange body, in particular connected to these holding plates.

[0039] The force can thus be transmitted directly via the retaining plates, which in turn are connected to the swivel flange body or - via the adapters - to the connecting flange body. In particular, the first retaining plate can be connected to the connecting flange body via a (first) adapter. The gearbox can then be mounted on this first retaining plate. An output of the gearbox can then be connected to the second retaining plate, which second retaining plate is itself mounted on the swivel flange body. By using adapters and retaining plates, different gearboxes (e.g. gearboxes of different sizes) can be used with the swivel module, whereby the swivel module can be easily adapted to different requirements.

[0040] It is preferably provided that the pivot module comprises at least one bearing, which bearing is preferably arranged between a third retaining plate connected to the connecting flange body and a fourth retaining plate connected to the pivot flange body, in particular connected to these retaining plates.

[0041] The use of such a bearing (also called a bearing module or bearing unit) ensures the rotatable mounting of the swivel flange body on the connecting flange body on the side opposite the gearbox. The bearing can also - analogous to the gearbox - be arranged between two retaining plates, in particular the third retaining plate, which is attached to the connecting flange body via a (second) adapter, and the fourth retaining plate, which is mounted on the swivel flange body, and connected to these retaining plates. This can provide a rotating mounting of the two retaining plates to one another, and thus also of the swivel flange body on the connecting flange body. By using adapters and retaining plates, different bearings can be used in the swivel module, which means the swivel module can be easily adapted to different requirements.

[0042] It is preferably provided that a first hydraulic unit is arranged within the connecting flange body, which first hydraulic unit is preferably connected to the flange receptacles of the connecting flange body via a respective support plate, wherein the support plates of the first hydraulic unit are particularly preferably connected to one another via rigid lines.

[0043] The first hydraulic unit initially serves to connect hydraulic lines of the boom, the holding arm of the first energy module and, if applicable, the holding arm of the third energy module. Accordingly, the first hydraulic unit can comprise a first carrier plate, which first carrier plate is connected to the first flange receptacle, a second carrier plate, which second carrier plate is connected to the second flange receptacle, and, if applicable, a third carrier plate, which third carrier plate is connected to the fourth flange receptacle. Connections for the corresponding hydraulic lines can be fixed in or on the respective carrier plates, so that the establishment of the hydraulic connections between the swivel module, boom and holding arm(s) is particularly simple. The connections in orThe hydraulic lines on the support plates of the first hydraulic unit can be connected to each other via rigid lines, since although the swivel flange body is movable (in particular, rotatable) relative to the connecting flange body, the individual components of the first hydraulic unit do not have to perform any (rotational) movements relative to each other. This allows the hydraulic lines to be routed particularly stably and well protected in the connecting flange body, significantly reducing the susceptibility of the swivel module to failure. The rigid routing of the hydraulic lines in the connecting flange body also offers the possibility of particularly reliable and effective insulation, which can increase the efficiency of the solar system in which the swivel module is used.

[0044] It is preferably provided that a second hydraulic unit is arranged within the swivel flange body, which second hydraulic unit is preferably connected to the flange receptacles of the swivel flange body via a respective support plate, wherein the support plates of the second hydraulic unit are particularly preferably connected to one another via rigid lines.

[0045] The second hydraulic unit initially serves to connect hydraulic lines of the holding arm of the second energy module and, if applicable, the holding arm of the fourth energy module. Accordingly, the second hydraulic unit can comprise a fourth carrier plate, which fourth carrier plate is connected to the third flange receptacle, and, if applicable, a fifth carrier plate, which fifth carrier plate is connected to the fifth flange receptacle. Connections for the corresponding hydraulic lines can be fixed in or on the respective carrier plates, so that the establishment of the hydraulic connections between the swivel module and the holding arm(s) is particularly simple. The connections in oron the support plates of the second hydraulic unit can be connected to one another via rigid lines, since although the swivel flange body is movable (in particular rotatable) relative to the connecting flange body, the individual components of the second hydraulic unit do not have to perform any (rotational) movements relative to one another. This allows the hydraulic lines to be guided in the swivel flange body in a particularly stable and well-protected manner, which significantly reduces the susceptibility to failure of the swivel module. The rigid routing of the hydraulic lines in the swivel flange body also offers the possibility of particularly reliable and effective insulation, which can increase the efficiency of the solar system in which the swivel module is used. It is preferably provided that the first hydraulic unit and / or the second hydraulic unit is / are each formed by a welded construction.

[0046] This enables particularly simple, stable and cost-effective production of the first hydraulic unit and / or the second hydraulic unit.

[0047] It is preferably provided that the connecting flange body and / or the pivoting flange body each comprise / comprise a cover, which cover closes an interior space formed between the respective fastening section and the cover, preferably except for openings for hydraulic lines and / or further openings for electrical lines, on the inside.

[0048] The term "inside" refers to the side of the connecting flange body or the swivel flange body that, in the operating position, faces the swivel flange body or the connecting flange body and thus, in a sense, lies inside the swivel module. The cover enables the formation of a protected and sealed interior space between the fastening section and the cover. In the case of a spherical segment-shaped fastening section, the cover can, for example, serve to cover the open area of ​​the spherical segment. The openings can include pipe outlets for the passage of cable harnesses from the support arms and pipe outlets for the passage of a main cable harness from the boom. The cable harnesses can be routed to the distribution box via these pipe outlets. This distribution box can provide clamp and / or plug connections and can also be used to connect a motor to operate the gearbox.The cover may have an opening that can be used to pass through hydraulic lines, in particular connecting the first hydraulic unit to the second hydraulic unit. Accordingly, the cover allows for the definition of passage points for hydraulic and / or electrical lines and cables from the interior of the connection and / or swivel flange body. This facilitates the connection of these lines and cables to other components of the swivel module or solar system, as well as the installation of the swivel module.

[0049] It is preferably provided that the interior is closed on the outside by means of positioning covers, which positioning covers cover through openings of the flange receptacles and preferably serve to fix the pipes.

[0050] The term "external" refers to the side of the connecting flange body or the swivel flange body that faces away from the swivel flange body or the connecting flange body in the operating position. Similar to the blanking plates, the positioning covers can be used to define the passage points for hydraulic and / or electrical lines and cables from the interior of the connecting flange body and / or the swivel flange body. This facilitates the connection of these lines and cables to other components of the swivel module or solar system, as well as the installation of the swivel module. If the connecting flange body and / or the swivel flange body includes / include pipes for electrical cables, these pipes can be attached to the positioning covers and thus connected to external cables and lines (of the boom and / or the support arms) via the positioning covers.It is preferably provided that the support plates have connection modules in order to be able to fluidly connect the first hydraulic unit and / or the second hydraulic unit to the support arms (holding arms) and / or the boom.

[0051] If the connection modules are provided directly on the support plates, this simplifies the connection of the hydraulic lines of the boom and / or the support arms due to the locally predefined or fixed connection options. This creates the prerequisite for particularly simple and time-saving installation of the swivel module on the boom or the support arms.

[0052] It is preferably provided that the connection modules are of modular construction, and in particular all connection modules comprise a connection body, wherein the connection bodies of the individual connection modules differ from one another at most by bores for pipe branches.

[0053] Different sealing sets can be used, resulting in different variants of connection modules. However, the connecting body or a welded part can always be designed the same. This reduces manufacturing costs and production logistics in mass production.

[0054] It is preferably provided that the connection modules comprise sliding sleeves and preferably O-rings.

[0055] Connection modules designed in this way enable a sufficiently sealed connection of all fluid-carrying lines of the support arms and / or the boom to the swivel module. In particular, the connection modules according to this preferred embodiment can absorb temperature-induced material expansion particularly well, thereby preventing leaks. Overall, the design of the swivel module can be kept simple and production costs low by using the connection modules according to this preferred embodiment.

[0056] Preferably, bores are provided or introduced into the ball heads of the connecting bodies. These bores can point toward the center of the ball heads, aligned with the axial direction of the rigid lines of the respective hydraulic unit or the hydraulic pipes (to be welded). In other words, the bores can be directed from the center of the ball heads toward a longitudinal axis of a section of the respective rigid line adjoining the ball head.

[0057] Each individual ball head can be drilled differently, in particular, the individual holes can differ from one another in their respective orientation. CNC machining allows these holes to be created particularly cost-effectively in the ball head. By drilling a suitable hole in the ball head of the respective connector body and subsequently welding the corresponding rigid line, a particularly advantageous line routing in the respective hydraulic unit can be achieved. In particular, this makes it possible to design the rigid lines of the hydraulic unit with virtually no bends.For example, the two hydraulic units of the connecting flange body and the swivel flange body can have a total of 12 rigid lines if the swivel module is to be connected to the boom and four support arms as intended. Of these 12 weldable pipes, only two pipes need to be designed with bends or bent sections due to the design described above. This reduces manufacturing costs.

[0058] It is preferably provided that connecting bodies are provided at the openings of the veneer, to which connecting bodies the piping for the rotary union is connected.

[0059] This creates a particularly simple connection between the first hydraulic unit of the connecting flange body and the second hydraulic unit of the swivel flange body.

[0060] Preferably, the rotary union is positioned axially centered between the connecting flange body and the swivel flange body.

[0061] As a result, a pivoting movement performed by the pivot flange body to transfer the second energy module from the operating position to the closed position can be followed by the rotary union without any forces acting on the rotary union which would lead to a deflection of the rotary union from its axis-centered position.

[0062] It is preferably provided that the rotary feedthrough is formed by two connecting bodies, which are preferably mutually fixed by a two-part holding fork.

[0063] In this way, the rotary union can be implemented particularly easily and at the same time a reliable connection can be created between the rigid lines of the two hydraulic units.

[0064] Preferably, at least one terminal box is provided which is mounted on the cladding.

[0065] By accommodating the terminal box on the panel, particularly on a side of the panel facing away from the respective interior space, a particularly simple connection of the electrical cables of the boom, the first and second support arms, and optionally also the third and fourth support arms is possible. In particular, the two terminal boxes, namely a first terminal box mounted on the panel of the connecting flange body and a second terminal box mounted on the panel of the pivoting flange body, can be connected to one another by a flexible cable or a cable with a flexible section, which cable is positioned outside the two flange bodies. This represents a particularly compact and space-saving, yet also extremely maintenance-friendly connection option.

[0066] Preferably, the terminal box includes a conduit for electrical cables and / or a plug-in connector. This facilitates the connection of electrical cables from the boom and / or the support arms to the swivel module. A (flexible) electrical connection between the terminal boxes of the swivel module is sufficient to connect these electrical cables.

[0067] Preferably, the terminal box provides a plug connection for the motor electrical system.

[0068] This makes it particularly easy to supply and control the motor, which transmits the swivel movement via the gearbox.

[0069] It is preferably provided that the connecting flange body and the pivoting flange body are arranged mirror-symmetrically to one another in a pivoting position, in which pivoting position the second energy module and / or the fourth energy module is / are arranged in the operating position, relative to a vertical plane, in which vertical plane a rotation axis of the rotatable mounting of the pivoting flange body on the connecting flange body lies.

[0070] This allows a particularly compact and space-saving design of the swivel module to be realized, especially with flange bodies shaped like spherical segments.

[0071] An object of the invention is also achieved by a system comprising the swivel module in one of the embodiments described above and the first energy module, which first energy module is fastened via its holding arm to the second flange receptacle of the connecting flange body, the second energy module, which second energy module is fastened via its holding arm to the third flange receptacle of the swivel flange body, the third energy module, which third energy module is fastened via its holding arm to the fourth flange receptacle of the connecting flange body, and the fourth energy module, which fourth energy module is fastened via its holding arm to the fifth flange receptacle of the swivel flange body, wherein the energy modules are positioned in the operating position at corner points of a square or rectangle, in the center of which the swivel module is positioned.

[0072] This system allows all of the above-mentioned advantages to be achieved; the above statements therefore also apply analogously to the system according to the invention. The arrangement of the energy modules allows solar systems that incorporate the system according to the invention to be operated particularly energy-efficiently.

[0073] An object of the invention is also achieved by a solar system comprising the system described above, wherein the connection flange body is fastened to a first boom of the solar system.

[0074] All of the above-mentioned advantages can be achieved with this solar system; the above statements therefore also apply analogously to the solar system according to the invention.

[0075] The solar system preferably comprises a further embodiment of the system described above, wherein the connecting flange body of the further system is attached to a second bracket of the solar system. This allows for a solar system with a total of eight energy modules to be provided, which can be folded onto one another in pairs in the closed position to form four sealed units.

[0076] It is preferably provided that a leakage chamber is formed between the positioning cover of the connecting flange body or the swivel flange body and an insert pot of the boom or the support arm (holding arm), from which leakage chamber a line is led to the outside.

[0077] The positioning cover and insert pot can form a gap called a leakage chamber, in which fluid collects in the event of a leak in the boom and / or the support arms. A line with a cap leads from this space. When the energy modules are in the operating position, the fluid can drain (downward). During routine inspections or to search for a leak, opening the cap can determine whether there are any leaks. This improves the user-friendliness and maintenance of the solar system.

[0078] Pipe outlets leading to a terminal box are provided at the respective flange mounts for the electrical cables from the support arms (holding arms) and the boom. The pipes lead to a terminal box. The connection modules are part of a hydraulic distribution system in the swivel module. When the holding arms and the boom are assembled, the piping from these components is automatically pushed into the connection modules and sealed with the hydraulic distribution system of the swivel module. The entire installation is completed by threading the electrical cables through, tightening the flange screw connection, plugging in the electrical system, and closing the terminal box. Incorrect installation is impossible, as care is taken to ensure that only the correct plug-in or clamp connections fit. Installation can be carried out by two people. Specialist personnel are not required for the installation work. Should a connection module develop a leak, the flange connection can be exposed by removing the holding arm.A new seal kit can now be installed from the outside. There's nothing to do with the hydraulic distribution system. This is a welded construction, so leaks aren't expected. Maintenance of this system isn't planned. It's foam-encased behind a panel and can't be opened.

[0106] Ways to implement the invention

[0107] Fig. 1 illustrates the task for mounting the collectors (mirror collectors, energy modules). The collectors are attached to support arms 1, which have flanges for fastening. Since four collectors are arranged spherically symmetrically, positioned at 90° to each other in a star shape when viewed from above, corresponding counterflanges, also arranged in this configuration, are provided for mounting on a preferably spherical body, the flange unit (swivel module). A further counterflange on this flange unit is provided for the boom 2, which has a flange identical to that of the support arms.

[0108] Fig. 2 shows the peripheral connections for hydraulics and electrical systems. Electrical cable harnesses 3, 4 and hydraulic lines 5.1, 5.2 extend from the support arms 1 and the boom 2. The main cable harness 3 is routed in the boom 2, while line 4 for the power electrical system (PV power) and, if applicable, sensor cables are routed in the support arms 1. During assembly, the electrical cable harnesses 3, 4 must be routed to a distribution box with clamp and / or plug connections by providing appropriate pipe openings. The hydraulic lines 5, supply and return 5.1, and the cleaning line 5.2 are to be connected by sealed insert connections to a hydraulic distribution unit (hydraulic unit), which connects the hydraulics 5 from the boom to the individual collectors. The connection is to be established automatically during assembly of the flanges of the support arms 1 and the boom 2.

[0109] Fig. 3 shows the specifications for how the collectors are to be opened and closed. Thus, the hydraulic pipes and cable harnesses from the pivoting support arms must be routed over the pivot axis.

[0110] Fig. 4 shows the connecting flange body 6 for receiving the support arms 1 of the collectors and the boom 2 in two views. This is preferably a solid die-cast part with mechanical machining. The flange receptacles for the support arms and the boom have threaded holes. Assembly should only be carried out from the outside, as the interior will be paneled and no access is provided for screw nuts. To reinforce the threads, it is conceivable to cast steel inserts with threaded holes. The spherical shape ensures high rigidity against bending and torsion. The flange bodies 6, 7 have flat surfaces 38 with threaded holes for receiving adapters 8, 9 and retaining plates 12 (see Fig. 7).

[0111] Fig. 5 shows the pivoting flange body 7 for accommodating the support arms 1 of the pivoting collectors. Both flange bodies (connecting flange body 6, pivoting flange body 7) can be manufactured using the same tool. The parts are easy to demold and can be manufactured using a two-part tool. Examples of suitable materials include aluminum die-casting or injection molding with metal inserts. The difference from the connecting flange body 6 lies solely in the covering of the connecting flange.

[0112] Fig. 6 shows the geometric position of both flange bodies 6, 7 in the open and closed state. Open means that when the collectors are connected they are open and in an operating position. When the pivoting flange body 7 pivots through 180°, the collectors move into the closed state (closed position). Since the collector surfaces must close precisely, mechanical machining of the flat surfaces of the flange receivers is advantageous. It is also advisable to provide locating pins (not shown here). This also applies to the flanges of the support arms 1 (holding arms 1) and the boom 2. As can be seen, the flange bodies 6, 7 are at a stop in both positions. This guarantees exact positioning at the end positions, particularly in the operating position and in the closed position.At the stop, the gear is preloaded, ensuring a backlash-free power connection and preventing damage from vibrations (gusts of wind). The motors can no longer rotate and therefore consume more power. The load change from tension to compression is detected by the control system, and a signal is sent to deactivate the actuators. Limit switches and the associated cabling can be eliminated.

[0113] Fig. 7 shows the rotatable connection of both flange bodies 6, 7. The swivel flange body 7 is stably mounted via the gearbox 10 and a bearing module 11 (bearing unit, bearing). Two adapters 8, 9 enable the precise installation of the gearbox unit 10 and bearing unit 11. Retaining plates 12, which hold the gearbox 10 and the bearing unit 11, are mounted together with the adapters 8, 9. The adapters 8, 9 can be die-cast or injection-molded parts. It is conceivable to use extruded aluminum profiles, which are available by the meter. This enables a modular design for the installation of different gearbox and bearing types, simply by adjusting the adapter depth via cutting. The bearing unit 11 is typical of a wheel bearing from the automotive sector and is therefore available ready-made with a seal and inexpensively as a mass product. The gearbox 10 is heavily geared and self-clamping.Ideally, a worm gear is used on the motor side and a planetary gear on the power side. Gearboxes of this type are very compact and can transmit high forces. Since these gearboxes are frequently used in industrial robots, a suitable gearbox should be found here without the need for special manufacturing.

[0114] Fig. 8 shows an internal cover 13 with the installation of through-pipes 28 for the electrical system in two views. For better illustration, the connecting flange body 6 is shown transparent. With the cover 13 and positioning covers 17, which are arranged on flange receptacles of the (shown transparent) connecting flange body 6, a protected and sealed interior is formed. The pipe outlets 14 serve to lead through the cable harnesses from the holding arms 1. The pipe outlet 15 serves to lead through the main cable harness from the boom 2. The cable harnesses lead into a distribution box that provides clamp and / or plug connections. The motor is also connected to this box. The cable from the motor 16 is preferably provided with a plug, as shown here.Visible are the pipes 28 for the electrical wiring, which are held by the positioning covers 17 and the cover 13. The cover 13 has a large opening 40, which serves as the hydraulic passage. If no hydraulic passage is provided, this opening is closed by a cover cap 37 (visible in Fig. 24).

[0115] Fig. 9 shows the hydraulic system (hydraulic unit) installed inside the two flange bodies 6, 7. These are two welded constructions. Connection modules 19 with hemispherical ends are welded (preferably spot-welded) or screwed into support plates 18. The ball heads have ball-centric holes in the axial direction of the individual connecting pipes. Each individual ball head is drilled differently. With precise positioning of the support plates 18, for example, by mounting them on the flange bodies 6, 7 or on a special fixture, CNC machining is a cost-effective method for manufacturing the holes. As can be seen, of the twelve pipes to be welded, only two with bends are necessary. The welding of all parts can be carried out fully automatically in series production. The connection modules 19.1 and 19.2 differ in the connection dimensions of the inserted pipes. The connection modules 19.3 and 19.4 are pipe connections that do not allow any axial displacement or rotation. As with 19.1 and 19.2, connection module 19.3 features a guide bushing for inserting a pipe socket. Further details can be found in Fig. 19.

[0116] Fig. 10 shows a detailed view of the connecting pipes to the axis-centered rotary unions or connection modules 19.1. The connection modules 19.1 assume the rotary movement and can also be referred to as "rotary unions" in this case. To prevent pressure loss due to the system pressure (up to 30 bar during operation), the two rotary unions or connection modules 19.1 are mutually secured by a two-part retaining fork 20.

[0117] Fig. 11 shows the entire hydraulic system inside the swivel module, consisting of the two welded parts (first hydraulic unit inside the connecting flange body 6, second hydraulic unit inside the swivel flange body 7) with the support plates 18 and the connecting pipes to the rotary union (19.1, 20). The hydraulic "internal assembly" of the flange bodies 6, 7 is achieved by mounting both welded modules on the support plates 18. The welded modules can be easily and precisely inserted and secured with nine and six screw connections, respectively. Insulating blocks are provided at the screw connections to prevent thermal bridges.This is a one-time assembly, as there will be no access to the finished part, as the interior of the flange body 6, 7 (the space enclosed by the fastening section of the respective flange body 6, 7, on the inside additionally by the facing 13, and on the outside additionally by the positioning covers 17) is filled with foam. The pipes into which the rotary unions 19.1 are inserted support each other in the bent area against the ejection pressure. It is conceivable to use a spot weld connection or another type of fastening.

[0118] Fig. 12 shows two views of protective insulation sealing the facings. There is a T-shaped insulation shell 22 and a fork-shaped insulation shell 21. Both insulation shells are split in two to facilitate assembly. Two-part sealing rings 24 are attached to the pivot points of the insulation shells 21, 22, which can be removed or installed using spring locks 23. This makes it possible to check for leaks in just a few steps. The two-part insulation shells 21, 22 are held together by sealing rings 24 and seals 25 on the facings. Cable ties can also be attached. These can be quickly replaced.

[0119] Fig. 13 shows the complete installation for the electrical and hydraulic systems on the connecting flange body 6. It shows a front and rear view, as well as a view of the interior (the cover is transparent). As can be seen, this is a compact unit that will not be opened again. The heat pipes (hydraulic unit) can be insulated and / or the entire interior can be filled with foam. With careful welding of the pipes, no leaks are to be expected.

[0120] Fig. 14 shows the overall electrical and hydraulic installation on the swivel flange body 7. The same applies here as already described in Fig. 13. Lines for cleaning and the passage for the main cable harness to the boom 2 are omitted or are not present here, since only the two support arms 1 of the energy modules need to be connected. Fig. 15 shows the electrical terminal box 26 with connection 16.1 for a motor cable 16. If the collectors are designed purely for thermal purposes, no electrical lines lead to them. The openings provided in the terminal box are closed by plugs 27. The terminal box 26 is mounted in a sealed manner on the cover 13.

[0121] Fig. 16 shows the entire installation with two terminal boxes 26, including all electrical conduits, in two views. The pipes 28, which are supported by the positioning covers 17 and the cover 13, are clearly visible. Pipes 28.1 are connected to the terminal boxes 26, which carry the electrical system (via flexible electrical cables 30) close to the rotation axis. The electrical cables 30 are enclosed in grommets 29 at the outlets of these pipes 28.1, thus ensuring a seal. The cables 30 are suitable for outdoor use and flexible, allowing them to move along the pivot axis.

[0122] Fig. 17 shows the complete swivel module in its delivered state in two views. All sealing sets (guide sleeve and O-ring) on ​​the flange mounts can be replaced from the outside (see Fig. 19 for details). To connect the electrical system, only the terminal boxes 26 need to be opened. Ideally, different plug connections are provided so that incorrect connection is not possible. The complete setup of the collector system and also the assembly with the swivel module presented here should not require any specialist personnel. The collector unit with holding arm always has the same design (no mirror-symmetrical parts, but identical parts). The hydraulic circuitry is designed so that the flow always has the correct flow through the supply and return lines. This is particularly important for steam-generating heaters. The line cross-sections are dimensioned so that the lines can be carried by both liquid and saturated steam.A subsequent replacement of a liquid-flow solar heater with a steam generator would be possible.

[0123] Fig. 18 shows details of the flange ends of the support arms 1 and the boom 2. The positioning cover 17 and the insert pot 31 form a gap. Water or liquid collects here in the event of a leak. A line 32 leads out of this space and is fitted with a cap 33. If the collectors are open or the energy modules are in the operating position, the water or liquid can drain downward from the gap. During routine inspections or when searching for a leak, opening the cap can determine whether everything is OK.

[0124] Fig. 19 shows individual components for the modular installation. There are five support plates 18 in the entire installation. These are attached to the flange bodies on the inside of the flange mounts via insulating washers 34. A corresponding recess 35 is provided to prevent heat conduction from the hot pipes to the suspensions and the cleaning line. The recess 36 also prevents heat conduction and serves as an opening for the electrical piping. The connection modules 19 are available in four versions (which are also referred to below with reference numerals 19.1, 19.2, 19.3 and 19.4). These differ only in the sealing sets. The first version of the connection modules 19.1 is available eight times for the supply and return flow from the collector arms, three times for the cleaning line and twice for the rotary union. The second version of the connection modules 19.2 is available two times for the supply and return flow from the boom.There are two versions of the third variant of connection modules 19.3 and the fourth variant of connection modules 19.4 each. The union nuts 41 in the third and fourth variants of connection modules 19.3 and 19.4 are used to tighten a seal, which in this case is a sliding sleeve 42. In the first and second variants of connection modules 19.1 and 19.2, the union nuts are provided to prevent the sliding sleeve 42 from being pushed out by the system pressure. This allows axial displacement of the pipes 44. The actual sealing is achieved via the O-ring 43. With the right material selection and precise manufacturing, leaks in the connection modules 19.1, 19.2, 19.3 and 19.4 can be ruled out. Designing for an operating pressure of 30 bar and a steam temperature of 235°C should not be a technical challenge. If a leak occurs at the flange mounts, the sealing set 42, 43 can be replaced by opening the union nut.

[0125] Fig. 20 shows a PV module attached to the support arm 1. This is modular because it is the same support arm 1 as the one intended for holding the mirrors (mirror collectors). In other words, various energy modules, such as a mirror collector or a PV module, can be attached and connected to the support arm 1. The PV panel or PV module can be quickly mounted and removed using a snap-on fastener (e.g., a bayonet lock).

[0126] Fig. 21 shows a concentrator system with mirrors (mirror-concentrating collectors) for power generation in a slightly open state - the second and fourth energy modules are between the operating and closed positions. The heat from the cooling can still be used for heating purposes. This technology shows great future potential for the development of corresponding solar cells. These should have a high efficiency (>25%) and only a slight drop in output at a temperature of 150°C. In this case, the heat could still be used for air conditioning and cooking purposes. It would be conceivable to use a steam engine for a second stage of power generation. The power could also be generated with a time delay using a two-phase storage system. This would provide a cost-effective method for indirect power storage. To ensure even cooling of the solar cells, direct evaporators (e.g.Heat pipes) are used. Direct steam generation also increases the efficiency of the process for further power generation. The swivel module requires full equipment (hydraulics, cleaning, and electrical systems), as shown in Fig. 17.

[0127] Fig. 22 shows another view of Fig. 21 with a better view of the swivel module. The seamless thermal insulation and encapsulation of the hydraulic system are clearly visible. Harmful environmental influences are completely blocked. In particular, the hydraulic units are concealed behind the panels or are completely housed within the interior of the connecting flange body 6 and the swivel flange body 7. The two hydraulic units are connected to each other via the rotary union surrounded by the insulating shells 21, 22 (see Figs. 11 and 12).

[0128] Fig. 23 shows a hybrid system. The outer collectors, or the second and fourth energy modules, generate electricity using commercially available PV panels with convective air cooling. The hydraulics are thus eliminated for the outer collectors (the second hydraulic unit and rotary union can be omitted). The inner collectors, or the first and third energy modules, generate high-temperature heat using water-flowing heating coils 38. The pivoting mechanism allows the PV modules (second and fourth energy modules) to be moved over the mirrors (first and third energy modules), creating an enclosed space when the second and fourth energy modules have reached the closed position. This also offers the possibility of providing automatic cleaning. The system is easy to implement. The heat can be used for cooling, heating, and cooking purposes. This could be an interesting variant for domestic use in single-family homes.In certain regions, this can achieve a virtually self-sufficient energy supply. The heat can also be used for seawater desalination and water treatment processes.

[0129] Fig. 24 shows another view of Fig. 23 with a better view of the pivoting module. The hydraulic outlet for the outer collectors is closed by a cover cap 37. If the PV module is removed, for example, due to a forecast of extremely high wind forces, the electrical system must be disconnected in the terminal box 26. The cables can then be pulled out via the through-pipes in the support arms 1 and in the pivoting module.

[0130] In summary, the swivel module is characterized by the rotatable connection of the two flange bodies 6, 7. The swivel flange body 7 is securely mounted on the connecting flange body 6 via the gear unit 10 and the bearing module 11. The two adapters 8, 9 enable the precise installation of the gear and bearing units 10, 11. The retaining plates 12, which hold the gear unit 10 and the bearing unit 11, are mounted together with the adapters 8, 9. The adapters 8, 9 can be die-cast or injection-molded parts. It is conceivable to use extruded aluminum profiles, which are available by the meter. This enables a modular design for the installation of different gear and bearing types, simply by adjusting the adapter depth via cutting. The bearing unit 11 is typical of a wheel bearing from the automotive sector and is therefore available inexpensively as a mass product, ready-made with a seal. The gear unit 10 is highly geared and self-clamping.Ideally, a worm drive is provided on the motor side and a planetary drive on the power side.
