Abstract
The utility model discloses a sound insulation cover, comprising a cover body arranged outside a sound source device and composed of a shell and a sound absorption layer connected to the inner wall of the shell, wherein the cover body is connected with the sound source device by a vibration isolator, a through hole is opened on the cover body, a muffling structure is mounted on the through hole and is a muffling pipe with a muffling material lined on the inner wall, characterized in that: a ventilation muffler is mounted on the top of the sound insulation cover, a muffling heat-radiation hole is arranged on one side surface of the sound insulation cover and in a rectangular bent shape. The sound insulation cover has the advantages: the nose is effectively reduced, the sound insulation cover is easily assembled and disassembled and its practicality is strong.
Description
Technical field
The utility model relates to a kind of sound insulation equipment, relates in particular to acoustic hood.
Background technology
The well-known effective measures that reduce noise shield machine with acoustic hood exactly, and the noise during some pressurized equipment operations is very big, can reach 99-104dB; Operating personnel's execute-in-place and near the environment the equipment have been had a strong impact on; Traditional acoustic hood structure is single, is not easy to the dismounting repair apparatus, and the ventilation of acoustic hood and sound insulation contradict; All the time influence the development of acoustic hood, therefore be badly in need of providing a kind of new technical scheme to address the above problem.
The utility model content
[purpose of the utility model is: to above-mentioned deficiency, provide a kind of and can effectively reduce noise, and be easy to dismounting, practical acoustic hood.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
Acoustic hood comprises and is located at the outside cover body of sonic source device that said cover body comprises shell and is connected in the absorbent treatment on the outer casing inner wall; Said cover body is connected on the sonic source device through vibration isolator, offers through hole on the said cover body, and said through hole is equipped with noise elimination structure; Said noise elimination structure is the hush tube that inwall is lined with deadener; The top of said acoustic hood is equipped with ventilation silencer, and a side of said acoustic hood is provided with the noise elimination louvre, and said noise elimination louvre is the rectangle bending.
Said cover body is a split-type structural, and said each several part jointing positions is provided with the sound absorption pad.
The bottom of said cover body is provided with universal wheel.
The shape of said cover body and the shape of sonic source device are complementary.
The acoustic hood of the utility model for preventing solid-borne sound transmission, is provided with vibration isolator between cover body and sonic source device; In order to guarantee that sonic source device can normally move and safeguard, on cover body, offer through hole, in the through hole noise elimination structure is installed; Noise elimination structure is the hush tube that inwall is lined with deadener; So neither reduce the integral body noise elimination effect of sound proof housing, can reach the ventilation cooling purpose again, in order to overhaul and to monitor conveniently; Cover body is a split-type structural, and said each several part jointing positions is provided with the sound absorption pad.Top at acoustic hood is equipped with ventilation silencer, can satisfy the air-conditioning requirement of sonic source device, and performance of ventilating is good; Side at acoustic hood is provided with the noise elimination louvre; The noise elimination louvre is the rectangle bending, can effectively dispel the heat, and guarantees the serviceable life of sonic source device.Bottom at cover body is provided with universal wheel, and it can make things convenient for moving of acoustic hood, has very strong practicality.
The utility model has the advantages that: can effectively reduce noise, be easy to dismounting, practical.
