Abstract

A tank, in particular for a liquid hydrogen reservoir, provided with internal rails for putting an equipment module in place, includes
a central portion provided with a wall, and at least one rail and preferably a plurality of rails, each of the rails being integrated in the wall of the central portion of the tank so as to be accessible from inside the tank, such rails allowing easier integration and fastening of a module comprising equipment inside the tank, so as to simplify the manufacture and assembly of the tank.

First claim

The invention claimed is:

1 . A tank for a liquid hydrogen reservoir, said tank comprising:
a central portion having a wall, the wall comprising at least a first elongate panel and a second elongate panel, at least one rail integrated in the wall between the first elongate panel and the second elongate panel of the central portion of the tank so as to be accessible from inside the tank, said rail arranged on an internal face with a slideway configured to receive at least one connecting element, said slideway allowing a translational movement of the one or more connecting elements, wherein each of the first and second elongate panels comprise a curved shape in cross section, wherein the at least one rail comprises:
an elongate base, the elongate base connected to and between the first elongate panel and the second elongate panel; and
first and second brackets extending from the base, wherein each of the first and second brackets comprises a first branch extending from the base and a second branch perpendicular to the first branch, wherein the second branches delimit a recess between the first branches and the base, and define an opening to the recess,
wherein the elongate base comprises a curved shape in cross-section, and wherein the first and second elongate panels and the elongate base have a same radius of curvature.

2 . The tank as claimed in claim 1 ,
wherein the rail is welded to the wall of the central portion of the tank.

3 . The tank as claimed in claim 1 , wherein the at least one rail comprises:
a plurality of longitudinal rails integrated in the wall of the central portion and oriented so as to have mutually parallel directions.

4 . The tank as claimed in claim 1 , further comprising:
at least one frame provided with passage openings, configured to be arranged transversely in the tank, by being mounted on the rails.

5 . The tank as claimed in claim 4 , further comprising:
a plurality of connecting elements, each of said connecting elements fastened to the frame via one of first and second ends thereof and having at other of the first and second ends a head configured to slide by cooperating with the rail and to be fastened to the rail.

6 . The tank as claimed in claim 4 , wherein at least one frame comprises a plurality of frames, the tank further comprising:
a module formed of the plurality of frames connected together via equipment, said module configured to be arranged in the tank, by being mounted on the rails.

7 . A liquid hydrogen reservoir, comprising:
a tank as claimed in claim 1 .

8 . A method for manufacturing and assembling a tank as claimed in claim 6 , comprising:
a manufacturing step (E 1 ) including manufacturing a tank provided with a central portion, said central portion having a wall in which a plurality of rails are integrated; a mounting step (E 2 ) including mounting equipment in a plurality of frames disposed side by side and provided with connecting elements, so as to form a module; an insertion step (E 3 ) including inserting the module into the tank by sliding heads of the connecting elements in the rails; and a fastening step (E 4 ) including, in a position in which the module is mounted in the tank, holding the module in position.

9 . The method as claimed in claim 8 ,
wherein the fastening step (E 4 ) includes, so as to hold the module in position, fastening the heads of the connecting elements to the rails.
