Abstract

A connecting system is accordingly provided for a line tube, which can be pivoted about a rotation axis of a solar-thermal installation, which line tube is filled with a carrier fluid, wherein the line tube extends between two ends and is connected, for transportation of the carrier fluid, at a first end via a flexible tube connection to a fixed-position fixed line and at its second end via at least one connection means to a further line tube. According to the invention, the line tube is supported such that the flexible tube connection experiences only forces acting at right angles to the rotation axis, and the connection means experiences only forces acting parallel to the rotation axis.

Abstract

A connecting system is accordingly provided for a line tube (4), which can be pivoted about a rotation axis (A) of a solar-thermal installation, which line tube (4) is filled with a carrier fluid, wherein the line tube (4) extends between two ends (4a, 4b) and is connected, for transportation of the carrier fluid, at a first end (4a) via a flexible tube connection (13) to a fixed-position fixed line (15) and at its second end (4b) via at least one connection means (11, 14, 16*) to a further line tube (4). According to the invention, the line tube (4) is supported such that the flexible tube connection (13) experiences only forces acting at right angles to the rotation axis (A), and the connection means (11, 14, 16*) experiences only forces acting parallel to the rotation axis (A).

Abstract

The invention relates to a device for connecting a fixed line to an absorber pipe of a solar-thermal power plant, at least one solar collector being able to perform a pivot motion about the absorber pipe, characterized by a) a flexible pipe connection (1) between the fixed line (4) and the absorber pipe (3) and a b) means for connecting the flexible pipeline (1) to the absorber pipe (3) with zero torque and/or zero force. Acceptable mobility of the solar collectors is thus ensured even at high temperatures and/or pressures.
