Definitions

  • the present invention relates to a method and a system for stowing a kite-like wind-engaging element designed for flying out.
  • the windage element is connected via a catchable Werner-Inshizadassatusky-Inshizadastowment element designed for flying out.
  • the windage element is connected via a catchable Werner-Inshizadastunization technique with a breakpoint and docking with obtaining the Switzerlandseilitati to a holding device.
  • a trained for flying and held on a catchable Switzerlandseilitati windage element is known from the prior art.
  • the pull rope can be wound, for example, on a winch cable.
  • Such Windangriffsetti be used for example for propulsion of ships or, after connection of the cable winch with a generator to generate energy.
  • the breakpoint constitutes in the context of the invention a point at which the Glasseilitati is held, so that a power transmission from the windage element to the breakpoint is possible.
  • the breakpoint is formed in the region of a cable winch, which is designed for catching and Fieren the Glasseilitati.
  • the term traction cable connection is to be understood widely.
  • the traction cable connection can only consist of one or more traction cables, which are directly connected to the wind engagement element.
  • the traction cable connection usually has a traction cable, which fans out into a plurality of control lines, wherein the control lines for controlling the wind engagement element are connected to the wind engagement element at a plurality of connection points.
  • a control pod is usually arranged between the traction cable and the control lines, which serves to shorten (fetch) or extend (fire) at least some of the control lines for controlling the windfall element.
  • Such a control is for example from the WO 2005/100150 A1 or from the WO 2008/031446 A2 known.
  • the docking of the wind engaging element to the holding device can for example take place via a windage element arranged on the docking adapter, such as in the WO 2005/100150 A1 or the WO 2008/019700 A1 disclosed.
  • a tension cable tension in process step c. exists when the hauling cable connection between a fixed portion of the hauling cable connection (hereinafter called holding section) and the wind engaging element is stretched when So a clamping force on the Ceiseilitati is transferred from the holding section to the wind engaging element. Since the wind engaging element is docked to the holding device, the tension cable tension is thus transferred from the holding section to the holding device.
  • the holding section can be formed by the breakpoint and in particular in the region of a cable winch.
  • the clamping force is preferably a defined force, which is preferably less than 20% and more preferably less than 10% of the rated load of the Switzerlandseilitati. In a preferred embodiment, the clamping force is in the range between 1% and 15%, more preferably in the range between 2% and 10% of the nominal load of the pull cable connection. The clamping force should be sufficient in the context of the invention to reduce slack in the cable connection and to minimize possible.
  • the hauling cable connection has a hauling rope and a plurality of control lines and in the context of the invention, the hauling or tensioning of the hauling cable connection is mentioned, then this means that the hauling rope is hauled in or that one or more control lines are hauled in or out or that both the traction cable and one or more control lines are caught or gefiert.
  • the towing cable connection is preferably obtained from the out-of-plane condition until the wind engagement element reaches an altitude which allows docking with the holding device. Preference is given to the wind engagement element during the retrieval and usually also at the beginning of the docking under a sufficient wind action, so that the Glasseiltagen between the breakpoint and the flying windage element is substantially stretched.
  • the traction cable tension is maintained or - if necessary - restored, it is ensured that the traction cable connection remains in a defined position and orientation after docking.
  • the tension cable tension is maintained even in the stowed state, so that the position and orientation of the Buchseilitati remains until unpacking and re-setting (or starting) of the windage element.
  • the wind engagement element is docked to the holding device during the period of stowage. More preferably, the docking connection between windage element and holding device is retained even in the stowed state. It has been shown that the Glasseilschreib can be safely maintained by this. If the docking connection remains, the process of stowing and a subsequent setting process can also be done much faster.
  • the traction cable tension is established or maintained by retrieving the traction cable connection.
  • the pull cable connection has a pull rope and at least one control line, which can be obtained and secured independently of the pull rope, it can be provided according to the invention that the pull rope and / or the Control line for establishing or maintaining the Ceilland is obtained.
  • An independent catching and fering of the control line is - as already mentioned above - possible, for example via a control cable arranged between the control cable and traction cable.
  • the wind engagement element is connected to a guide line, wherein the tension cable tension is established or maintained by retrieving the guide line.
  • the guide line is preferably designed to guide the wind engaging element by retrieving the guide line to the holding device.
  • the guide line can preferably be fetched and gefung independently of the Ceiseilitati. By retrieving the guide line, the tension cable according to the invention can be produced in this way and the wind engagement element can be simultaneously docked to the holding device.
  • the wind engagement element can basically have a fixed framework, which is connected at at least one connection point with the pull cable connection.
  • the tension cable tension can in this case be transferred from the connection point via the stationary frame to the holding device.
  • the wind engaging element is adapted to be brought into a reefed state.
  • a reefed state is a state in which the volume or outer dimensions of the wind engaging element is reduced by deformation of the flexible material of the wind engaging element. The process of refining is for example in the WHERE 2005/100150 or in the WO 2013/164443 described. When reefed, less space is required for subsequent stowage.
  • the wind-engaging element is connected to a reefing line, which is designed to bring the wind-engaging element into a reefed state by retrieving the reefing line.
  • the Reffleine can be fetched and gefung independently of the Glasseilitati. According to the invention, it can further be provided that the tension cable tension is produced or maintained by retrieving the reefing line.
  • connection points in addition to or alternatively to the recovery of the hawser connection
  • this movement of the connection points can be used to tension the control lines (and thereby the hauling cable connection) or to maintain an already existing tension.
  • the guide line and the reef lines are formed by a single line, such as in the WO 2008/019700 is described.
  • the wind-engaging element is first guided to the holding device, without the reefing taking place, with reefing taking place when the catching is continued.
  • the "docking" of the windage element to the holding device can be done by obtaining the guide line and / or the Reffleine. As explained above, by retrieving the guide line and / or the reefing line, a traction cable tension can be established between the wind engaging element and a holding section of the traction cable connection, whereby the wind engaging element is fixed and thus "docked".
  • the term “docking” is to be understood in the context of the invention insofar.
  • the holding device may have a catching device (in particular a cable winch) for retrieving the guide or refleccs.
  • the holding device may also have a deflection point for the guide / Reffleine on which the guide and / or Reffleine is deflected to allow a pick-up of the wind engaging element to the holding device.
  • the towing cable connection has a plurality of control lines for controlling the wind engagement element, which are connected to the wind engagement element at a plurality of connection points, it is basically not necessary for all the control lines to be tensioned after the tension cable tension has been established.
  • a proportion of at least 20% of the control lines, preferably at least 50% of the control lines, more preferably substantially all control lines are tensioned during the production or maintenance of the tension cable tension.
  • the windage element is preferably reefed before stowage. It is advantageous if the windage element so is formed so that in the reefed state, the distance of the connection points to the respective fanning points substantially coincides with the respective length of the control lines associated with the connection points. This condition is also called “Kugelreff" and is in the WO 2013/164443 explained.
  • the connection points are thus brought by the reefing in an optimal position, so that a tensioning of the control lines to minimize the slack is possible.
  • the control lines influence as little as possible and remain in the desired position and orientation. The Bergen, stowing and the subsequent setting of the windage element is thereby significantly simplified.
  • the traction cable connection is gripped in the region of a holding section, wherein the traction cable tension is established or maintained between the holding section and the wind engaging element. After the hauling tension has been established, it is possible for the hauling cable connection to be separated at a point located below the holding section. This can simplify the subsequent stowage.
  • the gripping of the Switzerlandseilitati can be done for example in the area of a control pod.
  • the wind-engaging element for stowing in step d. stowed within a protective cover wherein the wind engaging element is preferably enclosed by a movement of the wind engaging element relative to the protective cover thereof.
  • a movement of the wind engaging element relative to the protective cover may mean in the present case that the wind engaging element is at rest and moves the protective cover is that the wind engaging element is moved and the protective cover is at rest or that both are moved.
  • the holding device and the holding point or the holding portion may be arranged on a movable relative to the protective cover platform, wherein the platform for stowage of the wind engaging element is moved relative to the protective cover.

  • the mast can be tilted around the joint to stow the windage element.
  • the joint can connect to a floor element.
  • the joint can also be arranged between an upper mast section and another lower mast section arranged underneath. The tilting is preferably carried out so that the over the holding device is docked to the mast windage element is moved at the beginning of the tilting in a direction away from the holding section direction.

  • step d the holding section of the pull cable connection arranged between the breakpoint and the wind engagement element is moved laterally in a direction away from the holding device. Due to the lateral movement of the holding section, the wind engaging element, which is still docked to the holding device, are rotated and thereby stowed easier. A rotation can be achieved even easier if the holding device at the same time, as already described above, is moved downwards in the vertical direction.
