Title
(EN) SLIDING CONNECTION FOR COMPRESSED AIR STORAGE TANK MADE OF PRESTRESSED CONCRETE
(FR) CONNEXION COULISSANTE POUR RESERVOIR DE STOCKAGE D'AIR COMPRIME EN BETON PRECONTRAINT
Abstract
(EN)
The present invention relates to a pressure tank comprising at least two sections including a bottom (3). The junctions between the different sections may be of different types but comprise at least one sliding connection (2), preferably at least one sliding connection (2), the sliding axis being the longitudinal axis of a section of a substantially cylindrical portion (1) of the pressure tank. The sliding connections (2) allow the reduction or even elimination of the longitudinal stresses on the section of the substantially cylindrical portion (1), induced by the end-cap effect due to the internal pressure of the tank. The invention also relates to a means for storing and releasing energy comprising at least one compression means, at least one expansion means, at least one heat storage means, and at least one pressure tank as described above.
(FR)
La présente invention concerne un réservoir de pression comprenant au moins deux tronçons dont un fond (3). Les jonctions entre les différents tronçons peut être de différents types mais comporte au moins une connexion coulissante (2), de préférence au moins une connexion coulissante (2), l'axe de coulissement étant l'axe longitudinal d'un tronçon de section sensiblement cylindrique (1) du réservoir de pression. Les connexions coulissantes (2) permettent de réduire voir d'annuler les contraintes longitudinales sur le tronçon de section sensiblement cylindrique (1), induites par l'effet de fond due à la pression interne du réservoir. L'invention concerne aussi un moyen de stockage et de restitution d'énergie comprenant au moins un moyen de compression, au moins un moyen de détente, au moins un moyen de stockage de la chaleur et au moins un réservoir de pression tel que décrit précédemment.
