Description

A kind of sound-deadening and noise-reducing container

Technical field

The utility model is related to goods traffic equipment field, and in particular to a kind of sound-deadening and noise-reducing container.

Background technology

Container is to specialize in the large-scale goods container being used in turn., can be directly in consignor using container transshipment goods Warehouse loading, transport to consignee warehouse unloading, midway more change trains, ship time, changed the outfit without goods is taken out out of case.It is existing Using vertical striped Wavy steel plate as packaging box outer wall more than container, to improve load-bearing and impact resistance.However, in handling During stacked containers or land transportation, existing container is easily jolted by impact, cause it is horizontal or it is oblique collide with, produce it Stress deformation.

During land transportation, because vertical striped air drag is strong, a large amount of noises, influence transport workman and nearby residents are also easy to produce Healthy living.And in jolting, loosely easily collision produces endogenous noise to goods, is reflected through tank wall because fixed, noise is by force not It is fugitive.More than prior art noise reduction is thermally shielded by the way of built-in foams plastic material.Its not only effect it is poor, and once because Overheat or electrostatic burning, easily catch fire and cause fire, bring the loss of the person and property.Therefore, existing transportation industry needs one badly Plant intensity high, safety durable, the good container of soundproof effect.

The content of the invention

In order to solve problem of the prior art, the utility model provides a kind of sound-deadening and noise-reducing container, and it can be effectively weak Change the noise source that impact is produced, weaken propagation of the acoustic wave energy in container, and it is safe, it is sturdy and durable, it is difficult stress Deformation.

A kind of sound-deadening and noise-reducing container, including casing and chamber door, it is characterised in that the tank wall of the casing includes thread plate With inner panel, it is provided between the thread plate and inner panel on the outside of noise reduction layer, the thread plate and is provided with thread groove, the screw thread is recessed The screw thread of groove is double thread.The thread groove can effectively guide the sound that container top layer air and the thread plate are propagated Sound energy wave.Promote the flow spiral produced during land transportation to propagate, reduce horizontal windage, so that shock wave is weakened, effective noise reduction.Two-wire Screw thread can promote air-flow to be flowed with the thread groove, it is to avoid the disturbance that single thread vertical line section is caused to air-flow.

It is preferred that, in the thread groove, two thread rotary orientations of the double thread are oppositely arranged.The institute being oppositely arranged State double thread and ensure that container uniform stressed in stacking；And oblique and transverse strength can be strengthened, prevent stress deformation.

Further, the ratio of the flight pitch of the thread groove and the thread plate width is (3-6):1, lead angle Angle is 15 ° -35 °.

Originally it is new to ensure that air-flow effectively retreat acquisition lateral torsion with the helical groove spiral, extend vertical wind Journey, the longitudinal windage of increase, the horizontal Mach number of reduction.

Further, gusseted plate group is provided with the noise reduction layer, the gusseted plate group includes multiple sound trap plates, The left and right sides of the sound trap plate, is fixedly connected with the thread plate and the inner panel respectively；The neighbour of the two adjacent sound trap plates While being fixedly connected in the thread plate or the inner panel junction, the cross section of the gusseted plate group is in a zigzag.

Preferential, multiple sound traps are provided with the sound trap plate, the sound trap includes first quarter moon hole and noise-damping bowl, the noise reduction Bowl is covered on the corresponding first quarter moon hole and is fixedly linked with the straight flange in the first quarter moon hole.

It is preferred that, the noise-damping bowl is in arc surfaced, and the protrusion direction of two adjacent noise-damping bowls is opposite.

Further, the outer indention of the noise-damping bowl.The utility model is under conditions of Mach number is low in noise reduction layer, Using the sawtooth of the noise-damping bowl, make to produce disturbance in propagation process of sound wave, form micro- whirlpool.Micro- whirlpool can be used as micro- sound Trap absorbs acoustic energy, has significantly contained the propagation of noise.

The sound trap can absorb the acoustic irradiation of casing air-flow external source and the endogenous generation of casing goods, eliminate sound wave anti- Caused superposition is penetrated, and avoids the generation of second order sound source.

Further, the noise reduction layer is in closed structure.It is in middle vacuum state that it is internal.Air pressure is preferably in the noise reduction layer 133Pa-1333Pa.Under the premise of this novel high-strength is distortion-free, using vacuum to a certain degree, the noise reduction layer is further enhanced Erasure effect.

The utility model brings resultant effect to include：

The utility model simple structure efficiently, the problem of solving existing container noise big oblique low intensity.And it makes Windage flow spiral during automotive is retreated, and effectively impact of the reduction air-flow to container wall, the horizontal windage of reduction, noise reduction disappears Sound.
