Description
Technical field
The present invention relates to noise reduction technology fields, and in particular to a kind of clino-axis type muffler.
Background technology
Clino-axis type muffler is commonly used to be mounted on overpass and highway both sides, for highway and neighbouring resident
Area's noise reduction plays a role.By the path difference principle of ray acoustics, sound barrier is higher, and noise reduction is better.But sound-screen
Barrier is too high to bring many negative effects：1. as sound barrier itself highly increases, wind resistance area increases sharply, train pneumatic
Power and environment Wind effects greatly reinforce；2. with the increase of sound barrier height, foundation of road bed increasing, bridge static and dynamic loadings
It aggravates, to make project cost greatly increase.
Road construction personnel wish to design a kind of suction without increasing sound barrier height, can play good noise reduction
Sound silencer.Common suction muffler is designed to symmetrical structure, and often the effect of the side absorption noise of face road is much super
The effect for crossing the other side, undoubtedly generates huge waste.One kind that the present invention exactly designs in view of the above shortcomings of the prior art
It is obviously improved the suction muffler of noise absorption area.
Invention content
In order to solve the problems in the existing technology, the present invention provides a kind of clino-axis type mufflers.
Technical proposal that the invention solves the above-mentioned problems is：A kind of clino-axis type muffler, including shell, the first installation part,
Silencer mechanism, first installation part and the second installation part of second installation part and setting inside the shell are separately positioned on shell
Both sides, the shell are in integrally elliposoidal, and shell is arranged with 10 °~20 ° of angle tilt, and the shell includes outer layer ellipsoid
Face, middle level ellipsoid and internal layer ellipsoid, outer layer ellipsoid, middle level ellipsoid and internal layer ellipsoid are evenly distributed with several micropores, outside
It is equipped with the first cavity between layer ellipsoid and middle level ellipsoid, the second chamber is equipped between the middle level ellipsoid and internal layer ellipsoid
Body, first cavity is interior to be equipped with mineral wool, and sound-absorbing vacuolar membrane, first installation part, the second peace are equipped in second cavity
Piece installing is rack-mount by screw bolt and nut；
The noise-reducing structure includes connecting plate and is arranged in the concave-convex coarse glass epoxy in connecting plate upper surface, the connecting plate
It is arranged on the inner wall of internal layer ellipsoid, the glass epoxy is equipped with 7, and intermediate glass steel plate is vertically arranged, intermediate glass plates
The glass epoxy in left side is obliquely installed to the left and angle of inclination gradually increases from right to left, the fiberglass on the right side of intermediate glass plates
Plate is obliquely installed to the right and angle of inclination gradually increases from left to right；
Further, the outer layer ellipsoid and internal layer ellipsoid are made of galvanized sheet；
Further, the middle level ellipsoid is made of Foamed aluminum sound absorbing plate；
Further, the shell is obliquely installed to road direction, and the thickness of shell both sides is more than the thickness of cover top portion.
The present invention has advantageous effect：
The present invention uses three layers of shell, is equipped with micropore on the shell, and be equipped with sound-absorbing material between three layers of shell, noise is made to exist
Gradually decayed after cambered surface roundtrip in shell；The thickness of shell both sides is more than the thickness of cover top portion, can guarantee that noise passes through
The distance for crossing sound-absorbing material is longer, preferably absorbs the residual noise in cavity, and glass epoxy is arranged at each angle, can weaken each
The remaining noise in direction.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
In figure：The first installation parts of 1-, the second installation parts of 2-, 3- outer layer ellipsoids, the middle levels 4- ellipsoid, 5- internal layer ellipsoids, 6-
First cavity, the second cavitys of 7-, 8- connecting plates, 9- glass epoxies, 10- holders.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode the present invention is further illustrated.
As shown, a kind of clino-axis type muffler, including shell, the first installation part, the second installation part and setting are outside
Silencer mechanism, first installation part and the second installation part in shell are separately positioned on shell both sides, and the shell is in integrally ellipse
Spherical shape, shell are arranged with 10 °~20 ° of angle tilt, and the shell includes that outer layer ellipsoid, middle level ellipsoid and internal layer are ellipse
Spherical surface, outer layer ellipsoid, middle level ellipsoid and internal layer ellipsoid are evenly distributed with several micropores, between outer layer ellipsoid and middle level ellipsoid
Equipped with the first cavity, it is equipped with the second cavity between the middle level ellipsoid and internal layer ellipsoid, glass is equipped in first cavity
Glass cotton, second cavity is interior to be equipped with sound-absorbing vacuolar membrane, and first installation part, the second installation part are mounted on by screw bolt and nut
On holder；
The noise-reducing structure includes connecting plate and is arranged in the concave-convex coarse glass epoxy in connecting plate upper surface, the connecting plate
It is arranged on the inner wall of internal layer ellipsoid, the glass epoxy is equipped with 7, and intermediate glass steel plate is vertically arranged, intermediate glass plates
The glass epoxy in left side is obliquely installed to the left and angle of inclination gradually increases from right to left, the fiberglass on the right side of intermediate glass plates
