With the double nut 48 tightened to shorten the length of the compression spring 45, the side wall 52 is sandwiched by the pair of sandwiching portions 12 and 13, and then the double nut 48 is loosened to release the compression spring 45. The side wall 52 is sandwiched by the restoring force of the compression spring 45.
  • the fixing tool 4E is not divided into the inner fixing body 14 and the outer fixing body 15, the number of parts can be reduced. Further, since the pair of sandwiching portions 12 and 13 sandwich the side wall 52 only by the restoring force of the compression spring 45, the portion sandwiching the sidewall 52 and the portion generating the sandwiching force are located on the same straight line. For this reason, the fixture 4E can be fixed to the side wall 52 without generating an extra moment.

Abstract

L'invention concerne un dispositif de production d'énergie hydraulique qui peut être installé facilement et de manière peu coûteuse sur un canal d'eau sans nécessiter d'aménagement sur le canal d'eau ou autour du canal d'eau. Le dispositif de production d'énergie hydraulique (1) comprend : une unité principale de dispositif de production d'énergie hydraulique (2) ayant une roue (5) et un générateur électrique (6); un cadre de support (3) qui supporte l'unité principale de dispositif de production d'énergie hydraulique (2); et une pluralité d'outils de fixation (4A) qui fixent le cadre de support (3) à des parois latérales (52) sur les deux côtés du canal d'eau (50). Chacun des accessoires de fixation (4A) comporte une partie de positionnement de cadre (11) qui est disposée sur une surface supérieure de la paroi latérale correspondante (52) du canal d'eau (50), et une paire de parties de serrage (12, 13) qui s'étendent vers le bas à partir des deux extrémités de la partie de positionnement de cadre (11). Lorsque le dispositif de production d'énergie hydraulique (1) est installé sur le canal d'eau (50), des extrémités latérales du cadre de support (3) sont placées sur les parties de positionnement de cadre (11) et fixées à celles-ci. Ensuite, les accessoires de fixation (4A) sont fixés aux parois latérales (52) par serrage de la surface interne et de la surface externe de chacune des parois latérales (52) avec les paires de parties de serrage (12, 13).
