Description
Technical field
The utility model relates to a kind of ventilation pressure leakage sound barrier module for high-speed railway, and concrete is a kind of by regulating noise elimination blade to regulate ventilation to reach the sound barrier module of best pressure release object.
Background technology
Sound barrier for railway is usual apart from track comparatively closely (general distance rail center line about 4m) for reaching good noise reduction.In high-speed railway (train speed per hour >=200km/h), when train passes through at a high speed, railway sound barrier, can be subject to the joint effect of natural wind load and train parting load simultaneously, and this train parting load is that the compression wave produced by the train crossed causes.Under the acting in conjunction of two kinds of loads, produce powerful pulsating force by circuit both sides sound barrier component surface, in order to bear consequent mechanical load for a long time, sound barrier component, particularly the housing of metallic sound barrier member must have larger thickness.According to the consideration of reliability and economy, the metal forming manufacturing procedure of multidimensional is only feasible to having certain thickness material, thus limit supporting capacity.So in order to ensure necessary mechanical load-bearing capability, the area of each partiting sound member of railway sound barrier, particularly accessible length are restricted.Noise barrier stand column must be spaced and install shortlyer, the partiting sound member that quantity is many and less must be adopted, the installation of railway sound barrier and the manufacturing cost of component higher, the conventional road sound barrier component particularly metallic sound barrier simultaneously made, the utilization on railway traffic Noise measarement is restricted.
Therefore, be necessary to design a kind of ventilation pressure leakage sound barrier module, solve noise problem.
Utility model content
A kind of ventilation pressure leakage sound barrier module that the utility model proposes, is combined with sound barrier partiting sound member, forms the sound absorbing-insulating barrier of noise reduction and ventilation and pressure release one.
The technical solution of the utility model is achieved in that a kind of ventilation and pressure release type barrier module, comprise ring-shaped rigid frame, in described ring-type rectangular frame, vertical direction is arranged with many rotary screws in parallel, described rotary screw is provided with noise elimination blade, described noise elimination blade and rotary screw are connected, one end of described rotary screw is fixed with driven gear, the spur rack matched with driven gear is provided with in described ring-shaped rigid frame, ring-type rectangular frame is also provided with the adjusting screw(rod) matched with spur rack, in described noise elimination blade, is provided with sound absorption construction.
Further, described sound absorption construction is space network.
Further, sound absorption unit is coated with in the mesh of described space network.
Further, described noise elimination blade surface is provided with sound-absorbing coating.
Further, described noise elimination blade is column structure, the cross section circle of described column structure, oval or polygon.
The beneficial effects of the utility model are: a kind of ventilation and pressure release type barrier module of the present utility model, adopt rotatable noise elimination blade, realize the unrestricted choice to difference noise elimination scope and ventilation by the Windward angle of adjustment noise elimination blade, reach best pressure release effect; Also change the directive property of noise radiation simultaneously; Spur rack and driven gear can be coordinated to realize regulating with overregulating screw rod, and the sound absorption construction of blade of eliminating the noise make noise reduction better.The utility model structure is simple, easy to use, is applicable to promoting.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of ventilation and pressure release type barrier module as shown in Figure 1, comprise ring-shaped rigid frame 1, in described ring-type rectangular frame, vertical direction is arranged with many rotary screws 2 in parallel, described rotary screw 2 is provided with noise elimination blade 3, described noise elimination blade 3 is connected with rotary screw 2, one end of described rotary screw 2 is fixed with driven gear 4, the spur rack 5 matched with driven gear 4 is provided with in described ring-shaped rigid frame 1, ring-type rectangular frame is also provided with the adjusting screw(rod) 6 matched with spur rack 5, in described noise elimination blade 3, is provided with sound absorption construction.
Described sound absorption construction is space network.Sound absorption unit is coated with in the mesh of described space network.Described noise elimination blade 3 surface is provided with sound-absorbing coating 21.
Described noise elimination blade 3 is column structure, the cross section circle of described column structure, oval or polygon.
In actual use, user can regulate the angle of noise elimination blade 3 according to the wind direction of reality, by rotating adjusting screw(rod) 6, adjusting screw(rod) 6 drives spur rack 5 to move, spur rack 5 moves and drives driven gear 4 to rotate, and driven gear 4 is connected with rotary screw 2, and then driven rotary screw rod 2 rotates, rotary screw 2 rotates and the angle of noise elimination blade 3 is changed, and reaches best pressure release effect; And the net structure of eliminating the noise in blade 3 and sound absorption unit can be good at playing noise reduction, and the sound-absorbing coating 21 on blade 3 surface of eliminating the noise makes noise reduction better.
The utility model is a kind of energy-conservation, reliable, economic, practical device, easy to use, is applicable to promoting.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
