  • the horizontal double wall may be constituted by two circular flat strips 19 sealed with the vertical walls.
  • This rigid pipe can be of large section for the passage of high flows to feed the means 10 for projecting a fluid.
  • This pipe will, according to one embodiment, a water supply under a pressure of about 20 bar. The flow can be significant, about 20 m 3 / hour.
  • the rigid pipe 17 has an upper edge 20 on which is formed an inlet opening 21 for a fluid.
  • the support 1 further has a connecting element 22 for a tubular pipe, in particular flexible.
  • the connecting element 22 comes to bear around the opening 21, at least on the upper edge 20.
  • the tubular pipe, in particular flexible can rise from the connecting element, in particular passing through the passage 16 of the ring element 12, and a corresponding opening 60 on the upper part of the housing element 3.
  • the bore 23 is formed on an upper face of the connecting element 22.
  • the rear face of the element 22 is open on the inner recess 25.
  • the two lateral sides 26, 27 of the element are generally of trapezoidal rectangle shape and have two free edges 28, 29, at the rear face of the element, intended to be welded in a sealed manner to the inner wall of the cylindrical housing element 3.
  • the lower face of the connecting element 22 in which the outlet is formed has a U-shaped edge 30 intended to be welded in leaktight manner to the upper edge 20 of the rigid pipe 17.
  • the support also allows the attachment of a temperature measuring probe, in particular concrete.
  • this probe is, for example, secured to the lower end of an arm 31 projecting downwards in the tank.
  • the upper end of the arm 31 is secured, directly or indirectly, to the inner face 8 of the rectangular plate 7.
  • the fixing plate 7 may have several holes for the passage of fixing screws.
  • the fixing plate may also have blind holes, in particular oblong holes provided to cooperate with bands 2 of corresponding shape for the positioning of the accessories.
