Definitions

  • the present finding refers to improvements made to sets for generating current in generals, be they fixed or mobile.
  • generator sets a typical use of which is in emergencies, for example to provide electrical energy to the essential apparatuses of a hospital in the case of a black-out, briefly comprise an electrical machine, like an alternator, which is driven by a combustion engine, generally a Diesel-cycle internal combustion engine, all being installed on a suitable platform.
  • a combustion engine generally a Diesel-cycle internal combustion engine
  • the internal combustion engine is generally cooled by water, which flows in a radiator that is crossed by a flow of air driven by a fan controlled by the engine, and intended to cool down both the engine and the alternator.
  • generator sets are generally rather noisy and therefore there is a requirement to cut out or reduce as much as possible its noisiness, without of course altering the characteristics of the overall cooling system for obvious reasons.
  • the main purpose of the finding is, indeed, that of providing a silencing system for such generator sets that is able to fulfil the quoted requirement.
  • Another purpose of the finding is that of making a sound-proofing system that, as well as having excellent silencing properties, allows access to the various parts of the generator set, for example for control and maintenance interventions, both general and specific, in a particularly simple, quick and easy manner.
  • a further purpose consists of making a sound-proofing system capable of achieving the quoted goals in the context of a simple, rational, functional, strong and cost-effective constructive solution.
  • said generator set is of the type outlined in the preamble, or rather it comprises an internal combustion engine that is fitted onto a platform, and at the opposite axial ends of which are associated a current generator and a cooling fan suitable for creating a flow of fresh air that flows generally according to the direction taken up by the axis of the engine, typically in the direction that goes from the current generator to the cooling fan.
  • said platform is provided with an overlying generally parallelepiped sound-proofing shell that provides, at the bottom, a surrounding case that contains the engine and its additional parts, and takes care of channelling the cooling air flow, and at the top, a service chamber that provides two manifolds for fresh air and exhaust air, respectively, the first of which places the outside in communication with the underlying area of the case intended for the current generator, and the second of which places the underlying area of the case intended for the fan in communication with the outside.
  • the flow of air between case and manifolds takes lace through a horizontal wall that separates case and chamber.
  • Said horizontal wall preferably consists of a sound-absorbing baffle.
  • the set is practically completely surrounded by a sound-proofed jacket, obviously apart from the ports for the passage of fresh air coming in and exhaust air going out, respectively, which allows a drastic reduction in noise as has been able to be seen following specific tests carried out on various types of generator sets, obviously tested with and without the silencing system according to the finding.
  • said sound-proofed shell preferably consists of a box-shaped body that is open at the bottom suitable for resting on the engine-carrying platform, and removably fixed there through threaded members so as to totally uncover the engine in a short space of time.
  • said box-shaped body has hatches and removable panels intended for localised interventions.
  • the platform 1 can be of the type intended to be fixed to the floor, or of the type suitable for being arranged on a mobile, self-propelled or dragged means.
  • the generator set is of the known type and comprises, in short, an internal combustion engine 2, generally with Diesel-cycle, which on one side (on the left in fig. 3) is kinematically coupled with a current generator 3, typically an alternator, and on the other side (on the right in the same figure) is kinematically connected to a fan 4 with a radiator 5 in front for circulating the cooling water for the engine 2.
  • the fan 4 creates a flow of air that generally runs parallel to its axis in the direction that goes from the alternator 3 to the radiator 5 (see fig. 3).
  • the fresh air that reaches the generator set from the outside is indicated with A in the figures, whereas the exhaust air that leaves the generator set and discharges to the outside is indicated with B.
  • the elements making up the quoted generator set are received in the bottom part of a generally parallelepiped insulated shell 6 with a rectangular plan (figs. 1, 2 and 4).
  • the shell 6 is open at the bottom so as to be able to be slotted from above onto the platform 1, and be removably fixed there.
  • the same shell 6 is equipped with a horizontal separator baffle 9 (figs. 3 and 4) that divides it into a bottom case 60 and a top chamber 66 communicating with each other, where the first 60 encloses the generator set and the second 66 acts as a passage for the respective flows of fresh air A and exhaust air B.
  • a horizontal separator baffle 9 (figs. 3 and 4) that divides it into a bottom case 60 and a top chamber 66 communicating with each other, where the first 60 encloses the generator set and the second 66 acts as a passage for the respective flows of fresh air A and exhaust air B.
  • a vertical dividing wall 10 consisting of sheets of metal plate and sound-absorbing panels is arranged, which in plan (fig. 4) has a sinuate extension developing substantially according to a diagonal of the shape in plan of said chamber 66.
  • the chamber 66 is divided into two areas that in plan have substantially the shape of an elongated right-angled triangle extending generally parallel to the axis of the underlying engine 2 (fig. 4).
  • One of said areas acts as a manifold for fresh air A, and the other area, in the bottom right of the same figure, acts as a manifold for exhaust air B.
  • the manifold for fresh air A communicates with the area of the case 60 intended for the alternator 3 (fig. 3) through a generally trapezium-shaped horizontal opening 61 that is formed on the baffle 9 (fig. 4), and with the outside through a vertical window 161 equipped with a grate (fig. 1).
  • Said horizontal opening 61 and said vertical window 161 are arranged in substantially opposite positions with respect to the longitudinal development of the manifold for fresh air A (fig. 3).
  • the manifold for exhaust air B communicates with the area of the case 60 intended for the alternator 3 (fig. 3) through a rectangular-shaped horizontal opening 62 that is formed on the baffle 9 (fig. 4), and with the outside through a vertical window 162 equipped with a grate (figs. 2 and 3).
  • Said horizontal opening 62 and the respective vertical window 162 are arranged in substantially opposite positions with respect to the longitudinal development of the manifold for exhaust air B (fig. 3).
  • the fuel tank indicated with 20 in fig. 3, is removably arranged in a suitable side space formed on the platform 1.
