Definitions

  • a parabolic trough collector with at least one loop with at least one tube for pumping heat ther ⁇ mal fluid trough the tube.
  • the parabolic trough collector comprises at least one a loop fixing element for fixing the loop and at least one a counter weight for reduc ⁇ ing a probability for moving of the loop out of a rotation plane.
  • the loop fixing element and the loop are connect ⁇ ed via at least one rope.
  • the intention of the invention is to keep SBJ (single ball joint) assembly within or near the rotation plane.
  • the single ball joint assembly tends to move outwards its ro ⁇ tation plane due to frictions within the system.
  • the solution is to avoid this outwards movement using counter weights.
  • a rope is attached to the piping via a clamp near the middle ball joint or a other adequate place of the assem ⁇ bly.
  • the rope is guided via a ring or similar facility at ⁇ tached to a nearby placed fix installed structure, e.g. the end column of the respective Solar Collector Element.
  • Weights are attached to the other vertical end of the rope.
  • the weight shall be defined in a way that the ball joint as ⁇ sembly is kept within its rotation plan.
  • the weights are de ⁇ signed in a way that it can be reduced or increased as the friction within the Ball Joint Assembly can change e.g. by repacking of the ball joints.
  • the solution is very simple and easy to implement. No cutting of the system is necessary. As it is foreseen that the weights can be changed it is easy to react on changes of friction within the assembly and the ball joints can be kept in or near the rotation plane and with that the fiction of the assembly can be kept at a possible minimum.
  • One of the alternatives is to change the design of the ball joints in a way that the degree of freedom is reduced.
  • the figure shows a solar field 1 with a parabolic trough col lector 2.
  • the trough collector comprises a loop 21 with at least one tube 22 for pumping heat thermal fluid trough the tube .
  • a loop fixing element 23 for fixing the loop and at least one a counter weight 24 for reducing a probability for moving of the loop out of a rota ⁇ tion plane.
  • the loop fixing element and the loop are connect ed via at least on rope 25 which is guided by guided means 26.
  • the fixing element 23 comprises a clamp with which the rope is fixed an the tube 22 of the loop 21.
