According to an external acoustic resistant device, a vacuum circle cover approach to the surface of a railway is made for a train wheel, the middle of the circle cover is filled with metal sponge or other fillings, and an inner layer is fixed through a mesh screen; vacuum walls are arranged on the two sides of each rail of the railway, the vacuum walls are provided with fillings, and the height of the vacuum walls is a half of that of the train wheel.
Description
Technical field
The present invention relates to a kind of sound waves diffraction and block utensil, be called for short acoustic resistance, belong to field of Environment Protection.
Background technique
The ability to bear that sound wave sound surpasses people claims noise, and current manufacture noise is mainly the train of railway, is secondly vehicle on highway etc., and noise is divided into two classes: one, interior noise, as the waste pipe sound last person's gas of holding concurrently, gear-box sound etc.; Two, external noise: the sound that railway and train wheel hit mutually, form noise, the sound that hit mutually on the wheel on highway and road surface, forms noise, and has airborne dust effect; Interior noise must be digested and assimilated in engine exhaust pipe, external noise must absorb and control in the sealing of noise procephalon, current train wheel and railway, wheel of vehicle on highway beats road surface sound, just as tolling, appoint sound waves diffraction everywhere, the dust of rolling drifts everywhere, without any control measures.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of acoustic resistance, have the harmful components of removing tail gas concurrently, and can collect dust; Acoustic resistance has two kinds, and one, interior acoustic resistance; Two, outer acoustic resistance; Its technological scheme is: one, interior acoustic resistance 1, outlet pipe skin is made with vacuum double, inside is also that double-layer vacuum material makes, and interior acoustic resistance is set up in outlet pipe middle and lower part, and a roller cylinder is laid in centre, roller cylinder upper end is sealed, in the middle of roller cylinder, be round-hole mesh shape, added metal sponge in roller cylinder, or other filler, roller cylinder lower end is porose, the outer sieve-mesh that is of roller cylinder; Interior acoustic resistance 2 is contrary with interior acoustic resistance 1, that is: roller cylinder lower end is sealed, and surrounding is round-hole mesh shape, and roller cylinder upper end is unlimited, the outer added metal sponge of roller cylinder, or other filler.See Fig. 1.Two, outer acoustic resistance: train wheel is done a vacuum dome that approaches railway face, added metal sponge in the middle of dome, or other filler, internal layer tightens up with mesh screen; On railway line bar rail both sides, respectively lay vacuum wall, vacuum wall, with filler, is highly half of wheel; Railway cement pillow, with vacuum cover, cover, same vacuum wall in structure, due to the hub cap of train, the vacuum wall of railway, cement sleeper vacuum cover, hits railway sound waves by vacuum sound insulation by train wheel, and filler are digested and assimilated, sound waves has changed diffraction direction, extend earthward, the noise of train reduces or disappears, and sees Fig. 2.The wheel of highway, except settling vacuum cart wheel cap, also at hub cap, set up by grey box, after railway carriage, do one with the wide four sides casing equating of railway carriage, in casing, lay hairbrush in a row, outlet pipe afterbody is placed in the middle of hairbrush, below casing, be equipped with tank, feed tank is set up in railway carriage top, above feed tank, be equipped with intake pipe, be equipped with outflow box below, outlet pipe is connected with the weep pipe of traverse on casing, open conduit switch, water droplet is slipped into tank in hairbrush, in tank, be equipped with water pump, be connected with intake pipe, when tank water reaches water level, water pump starts automatically, when water level does not reach water level, close voluntarily, circulation and so forth, the hairbrush of four sides casing washes away by water, diluted the tail gas harmful gas of outlet pipe, wash away and washed dust, pollution can control environment, see Fig. 3.
Beneficial effect of the present invention is:
Control noise, airborne dust, the pollution of tail gas.

Embodiment
Interior acoustic resistance 1, outlet pipe skin is made with vacuum double, inside is also that double-layer vacuum material makes, and interior acoustic resistance is set up in outlet pipe middle and lower part, and a roller cylinder is laid in centre, roller cylinder upper end is sealed, in the middle of roller cylinder, be round-hole mesh shape, added metal sponge in roller cylinder, or other filler, roller cylinder lower end is porose, the outer sieve-mesh that is of roller cylinder; Interior acoustic resistance 2 is contrary with interior acoustic resistance 1, that is: roller cylinder lower end is sealed, and surrounding is round-hole mesh shape, and roller cylinder upper end is unlimited, the outer added metal sponge of roller cylinder, or other filler.See Fig. 1.Outer acoustic resistance: train wheel is done a vacuum dome that approaches railway face, added metal sponge in the middle of dome, or other filler, internal layer tightens up with mesh screen; On railway line bar rail both sides, respectively lay vacuum wall, vacuum wall, with filler, is highly half of wheel; Railway cement pillow, with vacuum cover, cover, same vacuum wall in structure, due to the hub cap of train, the vacuum wall of railway, cement sleeper vacuum cover, hits railway sound waves by vacuum sound insulation by train wheel, and filler are digested and assimilated, sound waves has changed diffraction direction, extend earthward, the noise of train reduces or disappears, and sees Fig. 2.The wheel of highway, except settling vacuum cart wheel cap, also at hub cap, set up by grey box, after railway carriage, do one with the wide four sides casing equating of railway carriage, in casing, lay hairbrush in a row, outlet pipe afterbody is placed in the middle of hairbrush, below casing, be equipped with tank, feed tank is set up in railway carriage top, above feed tank, be equipped with intake pipe, be equipped with outflow box below, outlet pipe is connected with the weep pipe of traverse on casing, open conduit switch, water droplet is slipped into tank in hairbrush, in tank, be equipped with water pump, be connected with intake pipe, when tank water reaches water level, water pump starts automatically, when water level does not reach water level, close voluntarily, circulation and so forth, the hairbrush of four sides casing washes away by water, diluted the tail gas harmful gas of outlet pipe, wash away and washed dust, pollution can control environment, see Fig. 3.
