Abstract

The utility model is a kind of acoustic barrier, its structure is that acoustic barrier body includes and the main part of horizontal plane and the rake being connected with main part top, rake tilts upward extension to close to noise source direction, angle between main part and rake is 110 °, convex contiguous block is set on the left surface of main part, coordinate convex contiguous block to set recessed link slot on the right flank of main part, hasp is set at the left and right edges of main part leading flank, two pairs of castors are set on four angles of the bottom of main part.The advantages of the utility model：Simple in structure effective, acoustic barrier tilts upward the diffraction angle and distance for being extended with rake to increase noise by main body, and noise is guided to the direction for not influencing factory's external environment or life, has preferable sound insulation effect；The setting of the concavo-convex connecting portion of acoustic barrier side makes the connection between acoustic barrier be more convenient accurately, and the setting of hasp makes connection more firm, and the setting of castor is more convenient the movement of acoustic barrier, is very suitable for promoting.

Description

A kind of acoustic barrier

Technical field

The utility model relates to a kind of acoustic barrier.

Background technology

There is the noise level in factory in country laws and regulations requirement, such as requirement and the critical outer edge portion of workshop, makes an uproar Sound level cannot disturb residents, and therefore, it is necessary to carry out noise control to some equipment in factory, avoid influencing or even jeopardizing outside factory Environment and resident living.Current noise control measure is generally realized using acoustic hood.

Because place limits, acoustic hood can not possibly be done very greatly, can not so be installed large-scale lifting machinery, be given overhaul of the equipments band Carry out very burden；And existing acoustic hood is generally isolated by the erect type main part installed on the ground into Row noise, is made an uproar When passing through main part diffraction can occur for the partial noise that source of sound is sent, on the ground nearby of the main part apart from acoustic barrier Still can be there are partial noise, so the sound insulation effect of this acoustic barrier is bad.

The content of the invention

The utility model proposes a kind of acoustic barrier, its purpose is intended to overcome drawbacks described above existing in the prior art, Realize effectively sound insulation.

The technical solution of the utility model：A kind of acoustic barrier, its structure includes acoustic barrier body, wherein insulating against sound Barrier body includes the main part with horizontal plane and the rake being connected with main part top, and rake is to close to noise source Direction tilts upward extension, and the angle between main part and rake is 110 °, and convex contiguous block is set on the left surface of main part, main Coordinate convex contiguous block to set recessed link slot on the right flank in body portion, hasp is set at the left and right edges of main part leading flank, main part Two pairs of castors are set on four angles of bottom.

The advantages of the utility model：Simple in structure effective, acoustic barrier is tilted upward by main body is extended with inclination Portion is guided noise to the direction for not influencing factory's external environment or life with to increase the diffraction angle and distance of noise, have compared with Good sound insulation effect；The setting of the concavo-convex connecting portion of acoustic barrier side makes the connection between acoustic barrier be more convenient accurately, to take The setting of button make it that connection is more firm, and the setting of castor causes the movement of acoustic barrier to be more convenient, and is very suitable for promoting.

Brief description of the drawings

Fig. 1 is the structure diagram of the utility model acoustic barrier.

Fig. 2 is the side view of Fig. 1.

1 in figure is that acoustic barrier body, 1-1 are that main part, 1-2 are that rake, 2-1 are that convex contiguous block, 2-2 are recessed companies Access slot, 3 be hasp, 4 be angles that castor, A are main part and rake.

Embodiment

The utility model is described in further detail with reference to embodiment and embodiment.

As shown in Figure 1, 2, a kind of acoustic barrier, its structure include acoustic barrier body 1, and wherein acoustic barrier body 1 wraps Include with the main part 1-1 of horizontal plane and the rake 1-2 being connected with main part 1-1 tops, rake 1-2 is to close to noise Source direction tilts upward extension, and the included angle A between main part 1-1 and rake 1-2 is 110 °, on the left surface of main part 1-1 If convex contiguous block 2-1, convex contiguous block 2-1 is coordinated to set recessed link slot 2-2, main part 1-1 leading flanks on the right flank of main part 1-1 Left and right edges at set hasp 3, set two pairs of castors 4 on four angles of the bottom of main part 1-1.

According to above structure, in use, according to requirements, the acoustic barrier of respective numbers is moved to by castor Position, adjacent acoustic barrier is clamped by convex contiguous block and recessed link slot, and, the inclination of acoustic barrier firm by hasp connection Portion is all tilted, it is necessary to then carry out inverse operation when dismantling to noise source direction.

Above-described is only the preferred embodiment of the utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to In the scope of protection of the utility model.
