Description

Hospital indoor drain pipe noise reduction device

Technical Field

The utility model relates to a hospital's interior decoration field especially relates to a device of making an uproar falls in hospital's indoor drain pipe.

Background

Life in a sound world, peripheral sound too big just becomes the noise, and family household has drainage pipe, and the drainage pipe is in the use, and the sound that sends when striking the drainage pipe when rivers flow is exactly one of the noise source, and the noise makes people's mood in disorder and impatient irascibility. Hospitals are one of the essential places in our daily life, and the noise generated by the drainage pipe is a common and headache problem for hospitals needing to be cleaner. Therefore, it is necessary to design a noise reduction device for the drainage pipe in the hospital room.

Disclosure of Invention

The utility model aims at overcoming the defect that prior art exists, providing a device of making an uproar falls of indoor drain pipe of hospital.

Realize the utility model discloses the technical scheme of purpose is: a noise reduction device for an indoor drain pipe of a hospital is provided with a noise reduction unit; the noise reduction unit is coated on the periphery of the pipeline; the noise reduction unit is sequentially provided with a polymer damping felt layer, an elastic base layer and an outer thin aluminum plate layer from inside to outside; the polymer damping felt layer, the elastic base layer and the outer thin aluminum plate layer are arranged in a clinging mode.

Furthermore, the thickness of the macromolecular damping felt layer is 3-5 mm.

Further, the thickness of the elastic base layer is 10 mm-20 mm.

Further, the elastic base layer comprises a sound passing plate and a base body which are arranged from inside to outside; a plurality of circular sound passing holes are uniformly formed in the sound passing plate; a plurality of sound absorption grooves are uniformly formed in the base body.

Further, the sound passing holes correspond to the sound absorption grooves in position.

Further, the substrate is an elastic substrate.

Further, the sound absorption groove is U-shaped.

Furthermore, a plurality of sound absorption channels extend from the inner wall of the sound absorption groove to the base body.

The thickness of the thin aluminum plate layer is 0.5 mm-1.0 mm.

After the technical scheme is adopted, the utility model discloses following positive effect has: the polymer damping felt layer mainly plays the effect of making an uproar of falling, and sound absorption groove 34 and sound absorption channel 35 in the elastic basic unit further absorb the weakening to the noise, and outermost thin aluminium sheet layer then is as the puigging, synthesizes its noise reduction effect of above-mentioned structure better.

Drawings

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of the local part a of the present invention.

The reference numbers in the drawings are as follows: the pipe 00, the noise reduction unit 10, the polymer damping felt layer 20, the elastic base layer 30, the sound passing plate 31, the base body 32, the sound passing holes 33, the sound absorbing grooves 34, the sound absorbing channel 35 and the outer thin aluminum plate layer 40.

Detailed Description

Referring to fig. 1 and 2, the utility model provides a noise reduction device for hospital indoor drainage pipe, which comprises a noise reduction unit 10; the noise reduction unit 10 is coated on the periphery of the pipeline 00; the noise reduction unit 10 comprises a polymer damping felt layer 20, an elastic base layer 30 and an outer thin aluminum plate layer 40 from inside to outside in sequence; the polymer damping felt layer 20, the elastic base layer 30 and the outer thin aluminum plate layer 40 are arranged in a clinging manner; the polymer damping felt layer 20 mainly plays a role of noise reduction, the elastic base layer 30 further absorbs and weakens noise, and the thin aluminum plate layer 40 serves as a sound insulation layer.

In this embodiment, more specifically, the thickness of the polymer damping felt layer 20 is 3mm to 5 mm.

More specifically in this embodiment, the thickness of the elastic base layer 30 is 10mm to 20 mm; the elastic base layer 30 comprises a sound passing plate 31 and a base 32 which are arranged from inside to outside, wherein the sound passing plate 31 is connected with the base 32 in an adhesive manner; a plurality of circular sound passing holes 33 are uniformly formed in the sound passing plate 31; a plurality of sound absorption grooves 34 are uniformly formed in the base body 32; the sound through holes 33 correspond to the sound absorption grooves 34.

More specifically, in the present embodiment, the base 32 is an elastic base, and the elastic base is preferably made of rubber, resin or polycarbonate, so that the sound absorption performance is further improved by using the good damping characteristic.

More specifically, in this embodiment, the sound absorbing groove 34 is U-shaped.

More specifically in this embodiment, the inner walls of the sound absorbing grooves 34 also extend into the base 32 to form a plurality of sound absorbing channels 35.

More specifically, in the present embodiment, the thickness of the thin aluminum plate layer 40 is 0.5mm to 1.0 mm.

The utility model discloses a theory of operation does: the noise that the inside rivers of drain pipe produced falls the back of making an uproar through polymer damping felt layer 40, and the noise of weakening passes through in sound hole 33 reachs sound absorption groove 34, under sound absorption groove 34 and sound absorption channel 35's further weakening, the noise reduction effect is better, and the cladding is also played syllable-dividing effect at outermost thin aluminum plate layer 40 at last to realize better noise reduction effect.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
