Abstract
The utility model relates to a cover plate type louver silencer. Herringbone folding pieces are arranged on the inner side of the silence at intervals to form an air flue, a silencing hopper is arranged on the outer side of the air flue and is structured in a way that the silencing hopper comprises a triangular plate, one set of triangular plate is symmetrically arranged on the outer side of the air flue, the silencing hopper further comprises a cover plate covering the triangular plate, and the upper end of the cover plate is connected with the outer side of the air flue through a hinge. As the silencing hopper is arranged on the outer side of the louver silencing air flue, the air intake area and the air exhaust area are large. The cover plate of the silencing hopper and the triangular plate are both connected with the outer side wall of the air flue in a hinged manner, so that the silencer is convenient to store and occupies a small area. The noise reduction effect during air intake and air exhaust can be improved and rain and sea waves can be prevented when the cover plate is opened, and the air flue is sealed when the cover plate is closed, so that the thermal insulation of the machine set can be carried out conveniently in a high and cold area.
Description
Technical field
The utility model relates to the denoising device of generator set, relates in particular to the cover-plate type blinds silencing apparatus for the advancing of generator set, air draft.
Background technique
Baffler is to stop sound transmission and a kind of device of allowing air-flow to pass through, is the important measures of eliminating air power noise.Baffler is mounted in the low noise device that falls on the air-flow path of aerodynamic force equipment (such as larger equipment of relief opening noise such as blower, air compressor, boiler exhaust mouth, generator, water pumps) or in the inlet and exhaust system.
Modern society is more and more stronger to the dependence of electric power, and various electric equipments need to have the stable power supply that continues, and is especially commercial, bank, hospital facility.But because energy scarcity and peak of power consumption undersupply often have and stop powering-off state.Generator set this moment power supply has in support guaranteed the normal operation of equipment.But it is very large to produce noise during generator set work, has directly affected people's work and life, and market is in the urgent need to the as far as possible little generator set of noise.Advance, the exhaust port silencing apparatus is the important device of improving generator set silencing case anti-acoustic capability.
The intake grill silencing apparatus of generator set silencing case of the prior art, the noise on its top leaks larger, noise reduction is not good, a kind of " compound air-inlet sound eliminator " disclosed such as practical new patent 200920041893.9, overcome the not good defective of top noise reduction of intake grill silencing apparatus, but its application has narrow limitation, can't be applied to ventilation and the noise reduction of exhaust port, without anti-wave function.
The model utility content
The applicant has narrow limitation for silencing apparatus in the above-mentioned existing production technology, without shortcomings such as anti-wave functions, provides a kind of rational in infrastructure, easy to operate cover-plate type blinds baffler, thereby the raising noise reduction, effectively rainproof and anti-wave function, and incoming air area maximization.
The technological scheme that the utility model adopts is as follows:
A kind of cover-plate type blinds baffler, described baffler inboard is spaced by the man type tabs and forms the air channel, the outside in described air channel is equipped with the noise reduction bucket, the structure of described noise reduction bucket is: comprise set square triangle, one group of set square triangle symmetry is installed on the outside, air channel, also comprise the cover plate that is placed on the set square triangle, described cover plate upper end is connected with the outside in air channel by hinge.
As further improvement in the technical proposal:
Described cover plate adopts sheet metal to consist of, and is provided with flanging around it, and the inner side surface of described cover plate posts acoustical cotton;
The sidewall butt of the flanging of cover plate and set square triangle, and be bolted;
Described set square triangle is connected by hinge structure with the outside, air channel;
The outside, described air channel can be equipped with a plurality of noise reduction buckets, the unlatching by cover plate and closed the advancing of air channel, the exhaust air rate regulated.
The beneficial effects of the utility model are as follows:
The utility model is installed the noise reduction bucket by the outside, blinds noise elimination air channel, and it advances, the air draft area is large.The cover plate of noise reduction bucket and set square triangle all adopt hinge type to be connected with the air channel outer side wall, and folding and unfolding is convenient, and floor space is little.Can improve when cover plate is opened into, air draft noise reduction, and have rainproof and anti-wave function, and regulate the advancing of air channel, exhaust air rate by the open and close of cover plate, can seal the air channel when cover plate is closed, be convenient to the insulation of unit equipment at severe cold areas.
The utility model is mixed flange and can be installed on the generator set silencing case, or on the power machine room wall, has the function of rainproof, ventilation, insulation, noise reduction.By test and actual the use, can drop to below the 75db complete environmentally acceptable requirement for the intake grill noise of Generator Set.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the cover-plate type blinds baffler of present embodiment, the baffler inboard is spaced by man type tabs 2 and forms the air channel, the outside in air channel is equipped with the noise reduction bucket, the structure of noise reduction bucket is: comprise set square triangle 4, one group of set square triangle 4 symmetry is installed on the outside, air channel, and set square triangle 4 is connected by hinge structure with the outside, air channel, and one group of set square triangle 4 can be around the one sidewall upset of the outside, air channel; Also comprise the cover plate 3 that is placed on the set square triangle 4, cover plate 3 upper ends are connected with the outside in air channel by hinge 1, cover plate 3 adopts sheet metal to consist of, be provided with flanging around it, the inner side surface of cover plate 3 posts acoustical cotton, after cover plate 3 lids place on the set square triangle 4, the sidewall butt of the flanging of cover plate 3 and set square triangle 4, and fixing by bolt 5.The air channel outside can be equipped with a plurality of noise reduction buckets, the unlatching by cover plate 3 and closed the advancing of air channel, the exhaust air rate regulated.
