Abstract

A louvered noise reducer in umbrella shape has a plurality of umbrella stands aligned in rows, wherein the uniqueness is that the row arrangement is implemented after the umbrella stands are connected through the connection bars. A plurality of sockets are arranged on the upper surface of the umbrella stand. The arc-shaped louvers are arranged inside the sockets. The louvers are connected and overlapped in sequence from top to bottom, and the sound-absorbing slots are formed between the adjacent louvers. A sound-absorbing cotton is arranged inside the umbrella stent. The bottom hollow web plates are inserted inside the opposite latch notches vertically arranged on both ends of the lower part of the umbrella stent. The hollow web bottom plate, the umbrella stent, the louvers, the connection bar are all made of glass fibre reinforced materials. The advantages are that the utility model adopts the glass fibre reinforced materials which can be in one-step pulling and extruding molding. So the inertia is great and the anti-wind capacity is strong. With the assembled structure, the utility model can prevent rain, snow and dust. The noise reducing effect is obvious because of the high opening ratio and the multiple-angle refraction of sound waves through the overlapped louvers. The device with nice appearance is anti-aging and corrosion resistant.

Description

Umbrella louvered denoiser

Technical field

The utility model belongs to highway, railway denoising device, particularly a kind of umbrella louvered denoiser.

Background technology

Existing denoiser is made of the semicircle arcuation aluminium sheet of surface drilling and the sound absorption cotton that is installed in the aluminium sheet inner surface, and the problem of its existence is: 1, can not rainproof, snow defence and dustproof, and easily aging, corrosion resistance is poor; 2, the surface of aluminum plate percent opening is too much, and the intensity of aluminium sheet is reduced greatly, and the wind resistance loading capability does not reach 300 kilograms/meter ²3,, undesirable with the acoustically effective of the equipped gobo of denoiser because aluminium sheet is the semicircle arcuation.

Summary of the invention

The purpose of this utility model is to solve the weak point that prior art exists, and provides that a kind of wind resistance loading capability is strong, rainproof, snow defence, dustproof, ageing-resistant, anticorrosion, excellent noise reduction effect, ornamental strong, specious umbrella louvered denoiser.

The utility model is achieved in that it has a plurality of umbrella supports, its special character is: put by being to arrange after the dowel connection between the umbrella support, be equipped with several sockets at the umbrella rack upper surface, in socket, be fitted with the arcuation blinds, described blinds forms the sound absorption hole from top to bottom successively between overlap joint and the adjacent blinds, in the umbrella support, be provided with acoustical cotton, longitudinally be provided with bayonet socket respect to one another in the umbrella support bottom that is positioned at two ends, in bayonet socket respect to one another, be fitted with hollow abdomen base plate, described middle base plate on an empty stomach, the umbrella support, blinds, dowel is fiber glass reinforcement.

Above-mentioned umbrella louvered denoiser is provided with the carriage corresponding with dowel in middle empty stomach base plate upper end, and described dowel is sitting on the carriage, and corresponding cradle is provided with gap on the umbrella support in the middle of being positioned at.

Above-mentioned umbrella louvered denoiser is provided with fin on middle empty stomach sidewall of the bottom plate, be provided with the draw-in groove corresponding with fin on the umbrella support in the middle of being positioned at, and described fin is stuck in the draw-in groove, to strengthen the fastness that connects.

The utility model has the advantages that: adopt fiber glass reinforcement to make, can a pultrusion, so moment of inertia is big, the wind resistance loading capability is strong; Integral body is modular construction, can be rainproof, snow defence, dustproof, and percent opening is many, can be by the blinds of mutual overlap joint with the refraction of sound wave multi-angle, noise reduction is obvious; Specious, ageing-resistant, anticorrosive.
