Definitions

  • Ventilation device for a liquid-filled pool
  • the invention relates to a ventilation device for a liquid-filled basin, with an air supply line which opens into an air distributor, to which distribution lines for the air supply into the basin are connected, the passage gaps between the distribution lines being arranged in the vertical direction and the distribution lines at their opposite ends are fastened to a rear cross member and the distributor and the rear cross member are connected to one another by connecting members so that they form a frame for the ventilation device.
  • Aeration devices for liquid-filled pools have distribution lines, for example in the form of perforated hoses, through which the air is supplied to the pools.
  • the distribution lines are fastened in the frame of the ventilation device and run side by side over the bottom of the basin.
  • the frame is formed by a horizontally guided air distributor, into which an air supply duct opens, the rear cross member and by longitudinal connecting members fastened on one side to the air distributor and on the opposite side to the rear cross member.
  • the inner space of the air distributor in the form of the cylindrical tube is connected to the inner space of the individual distribution lines.
  • the distribution lines are attached to the opposite end on the rear cross member.
  • the benefit lines are perforated over their entire length. This leads to a relatively intensive ventilation of the liquid not only above the ventilation device, but also in the area of the pelvic floor if the distribution lines are arranged at a certain height above the floor. This is ensured by foot frames that are attached to the frame of the device.
  • Aeration devices are used pull cables for lowering and lifting the device in or out of the pool. With the help of the pull cables, the ventilation devices are pressed to the bottom of the pool by means of the foot frames, the guides of the pull cables contributing to the stabilization of the ventilation devices. These measures only contribute to stabilization in one direction, while they are relatively ineffective in the other direction, which can be the water flow direction.
  • the essence of the invention is that the connecting beam forming part of the frame is at least one rigid strut located between the distribution lines.
  • the connecting carrier is a tube with a cylindrical cross section and passes symmetrically between connecting lines, the inner space of the connecting carrier being separated from inner spaces of the rear cross member and air distributor.
  • a stiffening element is arranged in the interior of the connection carrier, the outer edges of which bear against the inner surface of the connection carrier.
  • the air distributor and the rear cross member have a cylindrical cross section and their interiors are connected by means of the connecting lines. Crossbars are fastened to the connecting support, through which the distribution lines pass.
  • the frame is provided with the upper part of at least one stabilizer, the lower part of which is attached to the pelvic floor.
  • the basic rigidity of the ventilation device can be increased by inserting the stiffening element 11 into the inner space of the connection carrier 1 without adversely affecting the water circulation around the device.
  • the stiffening element 11 lies against the inner surface of the connection carrier by means of its outer edges.
  • the distribution lines 4 pass between the distributor 2 and the rear cross member 3 through the openings in the cross beam ⁇ fastened to the connecting member 1.
  • the crossbeams 6 are advantageously produced by spraying, their rounded shape and smooth surface contributing to the improved water flow of the device.
  • the frame is provided with pedestals 7 which are attached to the end faces of the air divider 2 and the rear cross member 3 and are used to set up the device on the pool floor.
  • connection carrier 1 in the form of the cylindrical Rohres can be used ideally for the connection with the pull rope 8 / Fig.4 / and for the installation of the device to the pool floor, whereby its mass together with material that can be inserted into its interior serves to load or raise the device.
  • the upper part 12 ′′ of the stabilizer 12 is fastened to the air distributor 2, the lower part 12 ′ of which is fastened to the pelvic floor.
  • the upper part 12 ′′ of the stabilizer 12 consists of two side parts 14 which are connected perpendicular to the axis of the air distributor 2 and to one another by means of the connecting bridge 15.
  • the connecting bridge 15 lies above the lower part 12 ' and is used by means of a screw connection for fastening the lower end of the pulling rope 8.
  • the pulling rope 8 serves to lower and raise the device in and out of the basin, whereby it is
  • ERSATZBL ⁇ (RULE 26) Part 12 'of the stabilizer 12 arranged guide goes through and is directed upwards after exiting the guide.
  • the side parts 14 are provided with support surfaces 16 arranged against the support surfaces of the lower part 12 ′ of the stabilizer 12. This arrangement stabilizes the ventilation device in the direction perpendicular to the axes of the distribution lines 4. Depending on the direction of the liquid flow, a pair of opposing support surfaces always lie on top of each other. It is also possible for all the support surfaces to lie on one another.
  • the traction cable 8 is provided with a protective tube 13 after it emerges from the stabilizer 12.
  • the protective tube 13 prevents the deposits of foreign matter on the pull cable 8 and thereby improves the passage of the pull cable 8 through the lower part 12 'of the stabilizer 12.
  • the protective tube 13 extends over the liquid level in the basin and by means of its movement in the direction of the pull cable 8 can be loosened Foreign substances are loosened.
  • the stabilizer 12 is arranged in the region of the connection carrier 1, and its upper part 12 ′′ is welded perpendicular to the connection carrier 1 and parallel or perpendicular to the distribution lines 4.

Abstract

Dispositif d'aération pour un bassin rempli de liquide comportant une conduite d'entrée d'air (5) débouchant dans un distributeur (2) auquel sont raccordées des conduites de distribution (4) pour l'amenée d'air dans le bassin, des fentes de passage étant disposées verticalement entre les conduites de distribution (4), ces dernières étant fixées à leurs extrémités opposées à une traverse arrière (3), le distributeur d'air (2) et la traverse arrière (3)étant reliés par une traverse de liaison (1) formant un tuyau creux disposé entre les conduites de distribution (4). La traverse de liaison (1) est disposée symétriquement contre les conduites de distribution (4), son intérieur étant isolé de l'intérieur du distributeur (2) et de celui de la traverse arrière (3). L'intérieur du distributeur d'air (2) est relié par les conduites de distribution (4) à l'intérieur de la traverse arrière (3). Le cadre du dispositif avec la partie supérieure (12'') comporte au moins un stabilisateur (12) dont la partie inférieure est reliée au fond du bassin.
