Definitions

  • the present invention relates to an installation hydraulic animation generating flow patterns two-dimensional.
  • the invention has great flexibility in terms of dimensions and shapes and offers great mobility at manufacturing and maintenance costs reduced.
  • One of the objectives of the invention is to achieve a hydraulic animation system which allows training a thin veil of water on a translucent wall, offering a flow on the two opposite faces of said wall, with two-dimensional flow patterns, while minimizing water flow.
  • the collection device according to the invention can be simply placed on the ground or introduced into a pit dug into the ground.
  • the mesh wall used in the invention is of preferably made of a Nylon® (polyamide-6,6) net, such as fishing nets or the like.
  • Nylon® polyamide-6,6
  • the dimensions and the configuration of the net mesh, as well as the title of the thread constituting the net, will vary with flow patterns that one wishes to obtain and depending on the height of the installation.
  • a thread with a titer between approximately 100 and approximately 435 tex (10,000 to 2,300 linear meters per kilogram), without this being limiting.
  • the net is advantageously fixed to the tank by a bar threaded through the meshes of said net, at the level from one end of said net, which bar is in abutment against two flat sections hinged to each other and taking said pinch net, one of said profiles being fixed to said tank, for example by a weld.
  • the net can be fixed to said tank by any other suitable means of attachment.
  • the net can be freely suspended from said tank, and thus having a draped, pleated or wavy appearance, but will be preferably also fixed at its opposite end and stretched between said ends.
  • the tank according to the invention can have a profile and variable length, depending on configuration that we want to give to the animation installation hydraulic. It can thus take the form of an arc of circle, a straight line or a polygon and have a circular, rectangular, square or trapezoid, for example.
  • the reservoir has at least one flow edge, along a part by means of which the liquid is poured on the net, via a spout.
  • surface filter foam including the density is close to that of the water after filling pores that constitute it, has the effect of coating the water before his fall.
  • Said filter foam is one aspect determinant of the invention because it has the effect of allow to minimize the flow and consequently reduce the volume of the tanks as well as their weight, this which also authorizes adjustments by the gallows even during operation.
  • obtaining a veil of liquid of a thickness as small as 0.8 to 2.7 mm, on a net about 6 m in height, for example, requires using liquid flow as low as 5 to 16 liters per minute and per linear meter of net. Variations, even light, such a low flow rate can lead to variations in thickness of the liquid veil which result in an undesirable heterogeneity of the patterns created by the net.
  • the homogeneity of the flow is further improved by the vertical mobility of the reservoir under the effect of adjustment means, since it offers an adjustment micrometric horizontality of the spout, by example in the event of ground movements, irregularities or deformation of materials.
  • the hydraulic animation installation according to the invention can be used in a variety of applications, and in particular as a separating partition and / or decorative element outside or in any type of premises.
  • Weir 1 which will be described in more detail by reference to Figure 3, includes a tank 2 and a beam 3, resting on the posts 6, the tank 2 and the beam 3 can have a length of several meters in depending on the configuration you want to give installation.
  • the tank 2 has a trapezoidal profile in section transverse, which is extended by a pouring spout 10, while that the beam 3 has a hollow parallelipiped structure made of a metal, such as aluminum or steel galvanized for example.
  • the tank 2 and the beam 3 are held together by 4 spaced jibs about 1.5 m from each other, the whole being covered with a cover 5.
  • the net 8 is fixed, by one of its ends, to the tank 2 from which it projects by marrying the shape of the spout 10 and, by its opposite end, in the collecting device 9. Said net is stretched between said tank 2 and said collection device 9, thanks ballast tube 37.
  • the collection device 9 which will be described in more detail detail with reference to Figure 2, is mounted in a pit (not shown) built into the ground, substantially directly above the pouring spout 10, in order to collect the liquid spilled from weir 1 onto net 8 and recycle this liquid, after filtration, to tank 2, by means of a suction pump 12, via line 7.
  • the filter foam 17 is for example a foam polyurethane-polyester.
  • the tank 2 is provided along its edge opposite the spout 10, with a flange 18 which projects towards the interior of the tank and on which are mounted first fixing means.
  • the first fixing means comprise profiles plates 21, extending over the entire length of installation.
  • the flat sections 21 are articulated one to the other by hinges 19, and adapted to pinch between them a first end of the net 8.
  • the first means net attachment also include a bar metallic 55 which is threaded through the meshes of said net 8, in the vicinity of said end, and rests in abutment against flat profiles 21.
  • the horizontal adjustment of the pouring spout 10 can even when the installation is assembled, simply acting on the adjusting screw 26.
  • the screw 29 thus allows a slight "clearance" between the tank 2 and the bracket 4.
  • the collection 9 comprises a tank 11 on which are pivotally mounted, at 31, two rows of gratings 32 defining between them a longitudinal space intended to receive the lower part of the net 8 and the liquid flowing over said net.
  • the second end 33 of net 8 is immobilized by fixing means made up of angle profiles, such that 22, in which the profiles are articulated one to the other by two hinges, such as 19 ', and adapted to pinch said second end 33 between them, so similar to the first means of fixing the net 8.
  • a means of tensioning the net which consists of a ballast tube 37, by example in galvanized steel supported by thread 8 at near its second end 33.
  • the tube 37 can by example apply a load of approximately 15 kg per net linear meter. It is intended to prevent any distension of the net 8, its use is particularly interesting to manage the lengthening and narrowing of the net as shown in dotted lines in Figure 4.
  • the collection device 9 also contains a 38 mesh filter, having a mesh of about 1 mm.
  • the mesh filter 38 is stretched between a first anchoring means 39 and a second anchoring means 45 to which it is respectively fixed by each of its ends as shown in figure 2.
  • the invention provides a simple and inexpensive way to form a thin continuous film of a liquid, having two-dimensional flow patterns, over the entire surface a flexible wall.
