Abstract
The utility model relates to an ultra-quiet power source vehicle noise-elimination carriage, which is characterized in that: two sides of the generator units inside the carriage are provided with a wind noise-reduction grid which is positioned at the wind inlet on the two sides of the carriage. An exhaust guide noise-reduction grid is positioned between back of the generator units and the back wall of the carriage; The smoke exhaust outlet of the generator units is provided with a smoke exhaust noise-reduction device connected by a smoke exhaust pipe and positioned in the carriage groove arranged at the top of the carriage. The utility model can fulfill the radiation, ventilation and noise reduction produced by the generator units and smoke exhaust as well as noise reduction to make the device is able to reduce the noise greatly when the generating units are in operation and enables the noise reduction meet the environmental-protection demands fully.
Description
Technical field
The utility model belongs to mobile power equipment supply technical field, is a kind of super-silent supply vehicle noise reduction noise elimination compartment.
Background technology
In technique known, overhaul as for open-air no electric field ground and outage the time or the supply vehicle of distribution use, generally in the compartment, all be fitted with diesel powerplant, when generator set was worked, noise was big especially, because the sound arrester imperfection in the compartment, and the air channel that is provided with is long, cause windage excessive, not only have influence on the unit noise reduction, and also be a kind of great noise pollution working environment.
The utility model content
The purpose of this utility model provides a kind of reasonable in design, can improve noise reduction, improves the super-silent supply vehicle noise reduction noise elimination compartment of working environment.
Realize that the technical scheme that the purpose of this utility model is taked is: this compartment has generator set, both sides at generator set, be provided with air intake noise reduction grid, this grid arrangement is at the ventilation inlet place of envelope both sides, compartment, between the exhaust outlet of the rear portion of generator set and envelope rear wall, be provided with air draft water conservancy diversion noise reduction grid, at the exhaust opening place of generator set, be connected with the smoke-discharging noise elimination device by smoke discharging pipe, this device is arranged in the envelope groove that car body top is provided with.
Described air intake noise reduction grid is formed by reaching the sticking sound absorption materials that applies of periphery on framework grid and the grid face, and air intake noise reduction grid is symmetrical installation in the two side, compartment, and is hinged with air door in the outside of grid.
Described air draft water conservancy diversion noise reduction grid is to be combined by sound absorbing layer and supporting layer, wherein, supporting layer is two-layer at least above tabular component, and an end is fixed on the generator set, the other end is communicated with exhaust outlet on the envelope rear wall, all is deposited with the sound absorbing layer that is made of sound absorption materials on supporting layer.
Described smoke-discharging noise elimination device is made up of the combination noise silencer of the noise silencer of a simply connected and parallel connection more than two at least, is communicated with by smoke exhaust pipe between the two, and constitutes two-stage smoke-discharging noise elimination device thus.
The super-silent supply vehicle noise reduction noise elimination compartment of making according to such scheme, be applicable to various portable supply vehicles, because denoising structure of the present utility model is rationally distributed, can solve vehicle-based generator set heat dissipation ventilation and smoke-discharging noise elimination effectively, the noise that makes generator set produce in the course of the work reduces greatly, noise in the compartment is reduced to about 60 decibels by original 100 decibels, meets the environmental demands of noise of equipment fully, has also reached the purpose of improving working environment thus.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the cutaway view in A-A cross section among Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, super-silent supply vehicle noise reduction noise elimination of the present utility model compartment, comprise a vehicle-based generator set 6, both sides at generator set 6, be provided with air intake noise reduction grid 2, this grid is arranged symmetrically in ventilation inlet 10 places of compartment envelope 1 both sides, form by reaching the sticking sound absorption materials that applies of periphery on framework grid and the grid face, and form the noise reduction ventilation inlet, be hinged with air door 9 in the outside of air intake noise reduction grid 2, when generator set 6 work, need to ventilate, air door 9 can be opened, when not working, air door 9 can be closed.Between the exhaust outlet 8 of the rear portion of generator set 6 and envelope rear wall, be provided with air draft water conservancy diversion noise reduction grid 7, this grid is to be combined by sound absorbing layer and supporting layer, wherein, supporting layer is two-layer at least above tabular component, and an end is fixed on the generator set 6, the other end is communicated with exhaust outlet 8 on envelope 1 rear wall, exhaust outlet 8 adopts shutter, can reduce the windage of ventilating, and is mainly used in windproof keeping off the rain.On supporting layer, all be deposited with the sound absorbing layer that constitutes by sound absorption materials.In this case, used sound absorption materials can adopt sponge or rock wool or glass fibre cotton or rigid foam etc. to have the material of hole.Exhaust opening place at generator set 6 is connected with smoke-discharging noise elimination device 4 by smoke discharging pipe 5, and this device is arranged in the envelope groove 3 that car body top is provided with.Combination noise silencer 4b by the noise silencer 4a of a simply connected and parallel connection more than at least two forms, and is communicated with by smoke exhaust pipe 4c between the two, and constitutes two-stage smoke-discharging noise elimination device thus.Like this, on the one hand can reduce watt loss, the noise that produces in can removing smoke effectively on the other hand obviously reduces the smoke evacuation noise of electrical generator, can also absorb vibration simultaneously, reaches sqouynd absorption lowering noise, improves the effect of working environment.
