Definitions

  • the invention relates to a photovoltaic system with posts arranged in at least one row at a mutual distance on an agricultural area, with solar modules provided between the posts, which are mounted on partial shafts of a common shaft, which run between two posts and are connected to one another in an articulated manner, and with two bearings each, which support the partial shafts at the end and which are held on a head of the associated post so that they can be pivoted about a horizontal pivot axis perpendicular to the partial shaft.
  • the course of the rows of solar modules is determined by the common corrugations on which the solar modules are fastened in rows, so that a section of land that is inclined in the longitudinal direction of the row causes a different overhead height along the row of solar modules due to the essentially horizontal course of the corrugation provided for each row of solar modules.
  • WO 2017/210432 A1 discloses a photovoltaic system with spaced-apart posts arranged in a row, which in pairs each have a support frame for solar modules that is pivotably mounted on the posts. These support frames can be pivoted using planetary gears provided in a common drive train, the support frames being attached to the rotatable housing sections of which.
  • the output side of the epicyclic gear on the input side in the course of the drive train of the two epicyclic gears each assigned to a support frame is connected to the input of the planetary gear on the outlet side by a partial shaft connected, while the outlet-side planetary gear is connected to the input of the input-side planetary gear of the following support frame in the series by a cardan shaft.
  • a photovoltaic system is known (WO 2018/075368 A1) in which the solar modules are provided on supports running between two uprights, which are mounted rotatably about a longitudinal axis and are drive-connected to one another by a cardan joint.
  • the two stub shafts of the cardan joint are each guided between the legs of a U-shaped bearing body, which is pivotably mounted in two side cheeks provided on the uprights, so that the two bearing bodies and with the bearing bodies the stub shafts of the cardan joint can be aligned in the direction of the partial shafts and can be fixed in the aligned swivel position relative to the side cheeks.
  • the cardan joints result in a common drive train for the successive solar module carriers.
  • the disadvantage is that, with the exception of a pivoted position of the solar modules, a torque load on the drive train must be expected in the respective pivoted positions of the solar modules due to the pivot arms receiving the solar module carrier, and that the cardan joint increases the angle of inclination between two consecutive solar module carriers.
  • the bearing arrangement is unsuitable for absorbing larger bearing forces, which are to be expected above all in gusts of wind.
  • the invention is therefore based on the object of designing a photovoltaic system with rows of solar modules that can be pivoted together in such a way that simple adaptation to the terrain can be ensured with a largely constant overhead height of the solar modules.
  • the invention solves the task in that the bearings have support rollers that are parallel to the partial shafts and receive the partial shafts between them in a load-dissipating manner, that the heads of the uprights comprise two supports for the end bearings of the partial shafts connected in the respective head area by cardan shafts, and that the supports are rotatably mounted about an axis forming the pivot axis for the bearings and rest at a distance from this axis on a pivot support that can be adjusted in height compared to the head (8).
  • the shaft accommodating the solar modules in a solar module row is divided into partial shafts that each extend between two adjacent uprights and are drive-connected in the joint area by a cardan shaft, offers an advantageous prerequisite for being able to move the uprights of a solar module row along a terrain profile that has a different elevation, so that the preferably uniform uprights are offset in height according to the terrain profile.
  • the connection of the partial shafts by cardan shafts allows a larger angle of inclination between the partial shafts because this angle of inclination is divided between two cardan joints.
  • the partial shafts run at an incline, axial forces must be expected, which must be taken into account when mounting the partial shafts.
  • the partial shafts can have radially protruding stop rings in the area of the end bearings, which are supported axially on support rollers aligned radially with respect to the respective partial shaft. The axial forces acting on the partial shafts are thus transferred by the support rollers to the carriers and from these to the uprights. In order to take temperature-related length changes of the partial shafts into account, this axial support of the partial shafts is only provided in the area of one of the two end bearings of the partial shafts.
  • FIG. 1 shows a detail of a photovoltaic system according to the invention in a schematic side view
  • FIG. 2 shows the mounting of two partial shaft ends connected to one another by a cardan shaft on the head of a post in a schematic side view on a larger scale
  • Fig. 4 shows a larger-scale section according to line IV-IV of Fig. 2, and
  • Fig. 5 shows a section according to line V-V of Fig. 2, also on a larger scale.
  • a photovoltaic system comprises at least one row of spaced apart uprights 2 on an agricultural area 1 and solar modules 3 arranged between these uprights 2, which are provided on partial shafts 5 that extend between the uprights 2 and are drive-connected to one another by cardan shafts 4.
  • the partial shafts 5 are provided with arms 6 distributed over their length, which accommodate a support frame 7 for the solar modules 3 .
  • the uprights 2 have an attached head 8 on which the bearings 9 for the ends of the two mutually facing ends of the two partial shafts 5 connected to one another in the upright area by the cardan shafts 4 are arranged.
  • the bearings 9 are each mounted so that they can be pivoted relative to the head 8 about a horizontal pivot axis perpendicular to the partial shaft 9.
  • a carrier 10 is provided which is mounted on an axis 11 which forms the pivot axis for the bearings 9 and is arranged in the head 8 .
  • the two carriers 10 for the bearings 9 of the partial shafts 5, which are opposite one another with regard to the cardan shaft 4, are pivotably mounted on a common axis 11, which, however, is not mandatory.
  • the pivoting adjustment of the carrier 10 and thus of the bearings 9 provided on the carriers 10 is carried out with the aid of a pivoting support 12 provided at a distance from the axis 11 for the respective carrier 10.
  • This pivoting support 12 is formed in the exemplary embodiment by a link guide 13 in which the carrier 10 is held in the adjusted inclined position by clamping screws 14.
  • bearings 9 for the partial shafts 5 are provided with support rollers 15 parallel to the partial shafts 5 and accommodating the partial shafts 5 between them in a load-distributing manner, as can be seen in particular from FIGS. 2 and 4, simple assembly conditions result despite good load transfer, because the partial shafts 5 only have to be placed on the support rollers 15 of the bearings 9.
  • Support rollers 15 in the lower half of the bearing are sufficient for load transfer.
  • guide rollers 16 can of course also be provided in the upper half of the bearing.
  • the arrangement of the support rollers 15 and the guide rollers 16 results in simple structural conditions if these support and guide rollers 15, 16 are mounted on bars 17 which connect the two bearing end walls 18 enclosing the partial shafts 5 with radial play.
  • the uprights 2 are first anchored in a row one behind the other at a mutual distance adapted to the length of the partial waves 5 in the ground of the agricultural area 1, before the inclination of the supports 10 with the bearings 9 corresponds to the straight line connecting the heads 8 of adjacent uprights 2, using the height-adjustable swivel supports 11.
  • the individual partial shafts 5 with the mounted solar modules 3 can then be inserted into the opened bearings 9 before the individual partial shafts 5 are connected to one another by the cardan shafts 4 .
  • the partial shafts 5 are joined by the cardan shafts 4 to form a common shaft which can be actuated from one end by an actuator 21, as indicated in FIG.
  • the solar modules 3 arranged in a row one behind the other between the uprights 2 can thus be pivoted together to take account of the position of the sun, but also to take account of wind loads and other requirements.
  • the agricultural area 1 also remains accessible in the area of the solar modules 3 for appropriate processing.
