| 摘要 |
<p>The present invention provides a stretcher system suitable for use in preventing the sagging of a transfer tube (P), through which a cold and/or hot fluid is transferred in solar trough field systems, due to the expansion resulting from temperature alterations, characterized by comprising at least one cord (2) which is in connection with said transfer tube (P); at least one support member (4) on which the cord (2) is guided so as to perform a sliding motion, and at least one counterweight (5) disposed at the end of the cord (2) extending from the support member (4). By virtue of the stretcher system developed according to the present invention, the transfer tube (P) is prevented from sagging under expansion, without having to increase the wall thickness thereof.</p> |
