Definitions

  • the present invention concerns a noise-reducing device for water run-off channels and in particular for water run-off channels of swimming pools with a sluice or overflow at the edge.
  • swimming pools with a sluice at the edge work based upon a scheme that foresees a water pumping/treatment plant that picks up water from a so-called refill tank and injects it into the pool.
  • the pool is equipped with a perimetric channel, total or partial, into which the water spills, in other words into which the water pours, passing over the outer edge of the pool itself.
  • the water that spills into the perimetric channel flows by gravity towards drains or run-off holes, usually arranged at the bottom or in any case in a low position in the channel. From the run-off drains through piping, connected to the drains, and suitable collectors, the water arrives in the refill tank.
  • the refill tank in addition to containing the water reserve necessary for feeding the pumps when there are no users in the tank, is also used to store the volume of water corresponding, amongst other things, to that which spills into the perimetric channel as a consequence of the entry of possible users into the water.
  • the purpose of the present invention is that of solving the problems of the prior art by providing a noise-reducing device that allows the sucking effect to be reduced and the noises of falling to be cut down.
  • Another purpose of the present invention is that of providing a noise-reducing device that is easy to install and cost-effective to make.
  • a noise-reducing device is characterised in that it comprises a floating plate, suitable for being inserted into the run-off channel, in turn comprising means for staying in engagement with the run-off drain as the water level in the channel varies and spacer means for providing a water passage section, also with zero water level in the channel.
  • Such run-off channels are usually provided at the bottom, or in any case in a low position, with run-off drains connected, in a known way, by means of piping, not shown, to at least one refill tank.
  • the noise-reducing device comprises at least one floating plate 2 of a size such as to allow it to be inserted into the run-off channel 13 and to allow all of the area involved in the falling of the water into the drain to be covered.
  • the floating plate 2 is in turn equipped with engagement means 3 for the run-off drain 14 and with spacer means 4 suitable for providing a passage section for the water, irrespective of the water level in the run-off channel 13.
  • the means 3 that allow the floating plate to stay engaged with the drain 14 irrespective of the water level that spills over the edge 15 of the pool and pours into the channel 13, are represented by a projecting tooth 5 arranged centrally in the lower portion of the floating plate 2.
  • the projecting tooth 5 is of a size such as to be inserted in the drain 14 and not significant block the water passage section in the run-off drain.
  • the tooth 5 also has the function of centring the plate 2 with respect to the drain 14.
  • the projecting tooth 5 is of a suitable length that allows it, and consequently allows the floating plate 2, to always remain engaged with the drain 14, irrespective of the amount of water that enters into the run-off channel 13.
  • the projecting tooth 5 is of a length equal to the maximum at the depth h of the run-off channel 13.
  • the spacer means 4 comprise at least three shaped projections 6 suitable for resting upon the bottom of the channel 13 in minimum or zero water level conditions to make water passage sections, towards the drain 14, as shown in figure 3.
  • six shaped projections 6 are foreseen three of which are arranged at an end of the plate 2, suitably spaced apart to create the water passage sections, and three, again spaced apart, at the opposite end with respect to the tooth 5.
  • the floating plate 2 is made from flexible floating material, such as an expanded foam, but it could, however, be made from any other floating material without departing from the scope of protection of the present invention.
  • the plate 2 remains rested at the water surface not allowing the passage of air into the drain 14.
  • At least two structural rigidifying elements 9 are foreseen, arranged centrally, suitable for avoiding the inflection of the plate 2 itself caused, for example, by sucking phenomena.
  • the rigidifying elements 9 consist, as shall be shown more clearly in figure 1, of further projections, suitably shaped, bound at the bottom to the floating plate and arranged transversally to the middle line of the plate 2.
  • rigidifying elements 9 are equipped with bevelled edges so as not to significantly reduce the water passage.
  • the device 10 Inserted in the run-off channel 13, with the tooth 5 engaged in the run-off drain 14, the device 10 according to the present invention constitutes a sort of floating plug that covers the possible left opening of the water in the drain 14 in minimum water level conditions in the channel 13, in such a way preventing sucking and cutting down the noise of falling.
  • the noise-reducing device, object of the present invention could, indeed, be used to cut down or reduce the noises in any run-off channel of a fluid provided with holes or drains at the bottom or, in any case, low down in the channel.
