Definitions

  • the invention relates to the winding and / or unwinding of a sheet such as a cover for a basin filled with liquid, in particular for a swimming pool. It also relates more particularly to the hydraulic drive drum for winding or unwinding such a cover, or any other tarpaulin.
  • the present invention aims to remedy these drawbacks, and relates to a drive drum for covering a pool filled with liquid (pool), comprising a cylinder which can rotate between the side walls of a pool with an internal hydraulic device.
  • rotary drive which comprises a sealed drive housing provided with a piston determining two chambers and means for supplying or discharging the fluid from each of these chambers alternately, drum characterized in that the housing is arranged to slide without rotating parallel to the cylinder wall, that it is provided externally with at least one helical rib, cooperating with at least one roller provided on the internal wall of the cylinder, so that the sliding of the housing causes the rotation of the cylinder, and the winding or unwinding of the basin cover, or any other covering.
  • the piston is fixed at the end of a hollow rod passing through one of the bottoms of the housing. In this rod passes two fluid lines opening one in the chamber located beyond the piston, the other in the chamber below the piston.
  • the piston being fixed the sending of fluid in one chamber with evacuation of the fluid from the other chamber (and vice versa) obliges the housing to slide along its axial supports, in particular on the hollow rod and its piston. Due to the presence of ribs, the sliding of the housing is only possible by driving the cylinder in rotation.
  • the horizontal roller or drum is immersed transversely in the basin, and can pivot between the vertical walls using the parts which support it references 12 and 13.
  • the drum is formed externally by the cylinder 1 closed at its ends by plates 14 and 15.
  • Inside the cylinder 1 is a hydraulic cylinder comprising a cylindrical box 2 closed in a sealed manner using a solid plate 16 on one side, and a plate 17 pierced in its center for the passage of the axial rod 3, using one or more O-rings 18 or not.
  • the end of the rod 3, outside the box 2 is secured by the cylindrical support 19 on the closing plate 15 of the cylinder 1 so that the latter can rotate independently of the rod 3
  • the pipes d 'fluid supply have not been shown in the figure, but they pass inside the hollow rod 3.
  • the rod 3 ends with a piston 4 perforated by a hole 10 for supplying or discharging fluid into the chamber 8.
  • a hole 10 for supplying or discharging fluid into the chamber 8.
  • another hole 11 enabling the fluid to be brought into or discharging into the chamber 9.
  • Seals 20 allowing 'prevent any circulation of the fluid from chamber 8 to chamber 9 and vice versa.
  • a helical rib 21 which cooperates with rollers 6, 7 provided inside the cylinder 1.
  • the rib can be obtained by any known means, or be constituted by an insert, but in in all cases, it has well-defined side walls, preferably perpendicular to the axis of the drum. One of these walls contits the raceway of the roller 6, while the other walls cooperates with the roller 7.
  • each roller is perpendicular to the drum and therefore to the wall of the cylinder 1.
  • a larger window is cut in the cylinder than the said roller.
  • the roller is fixed to a support sheet having the cylinder curve and dimensions greater than those of the window. Then, the roller is introduced through the window and the support is fixed to the cylinder.
  • the edge of the window and the edge of the support are sliced, so that said support is embedded in the cylinder.
  • the rotational drive can be obtained by a single roller and a single rib, but with non-negligible risk of play. You can also use a single roller between two ribs. It is also possible to combine several rollers with several ribs.
  • the axis 3 can pass through the partition 15 and be secured directly on a support integral with the wall of the basin.
  • the drum described above can rotate under ordinary water delivery pressure, but preferably this, to maneuver large blankets, a fluid pressure of the order of ten to twenty bars is used.
  • the cylinder can also withstand high pressures, which makes the drum adaptable for many applications, and the operation of tarpaulins other than pool covers.
