Description

Technical Field

[0001] The present invention relates to the field of sound-absorbing barrier devices used in rail transit, and specifically to a wedge-shaped detachable sound-absorbing barrier for rail transit. Background Art

[0002] In the prior art, the wedge-shaped sound-absorbing barrier is specifically composed of a tip and a base. In the prior art, the tip of the wedge-shaped sound-absorbing barrier is usually designed as a wedge shape, with a fiberglass cloth or plastic window screen covering the outer layer and a porous material (such as glass wool felt, slag wool or foam plastic) filled inside. Its tip design can effectively absorb sound energy, block and slow down the transmission of sound waves, and effectively improve the sound absorption effect, so it is widely used.

[0003] The structures of the wedge-shaped sound-absorbing barriers in the prior art are, for example: "A Sound-Absorbing Wedge" disclosed in Publication (Announcement) No.: CN201317983Y; for example: "A Composite Sound-Absorbing Wedge" disclosed in Publication (Announcement) No.: CN108487487A; for example: "An Easy-to-Install Sound-Absorbing Wedge" disclosed in Publication (Announcement) No.: CN206189630U.

[0004] The wedge-shaped sound-absorbing barriers in the prior art are basically designed as wedges, with the structure being too unique to cause inconvenience in installation. Moreover, the existing wedge-shaped sound barriers are all designed for integral installation, which is not convenient for installation and disassembly.

[0005] Especially, when the material of the sound-absorbing barrier is damaged or corroded, it cannot be conveniently replaced, or a whole piece of sound-absorbing material needs to be replaced after the material is corroded, wasting costs.

[0006] Moreover, there is another drawback of the sound-absorbing barriers installed on both sides of the track, that is, dust is easily accumulated at the end face position of the sound-absorbing barrier, resulting in the surface of the sound-absorbing material being covered by dust, making it difficult for sound waves to enter the sound-absorbing material to be absorbed, seriously affecting the sound absorption efficiency; and the existing wedge-shaped sound-absorbing barriers are more likely to accumulate dust due to the tip shape of the head, and due to the special shape, it is very troublesome to clean the dust, seriously affecting the sound absorption effect.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a wedge-shaped detachable sound-absorbing barrier for rail transit that is convenient to disassemble and can improve the sound absorption effect. Summary of the Invention

[0008] The purpose of the present invention is to provide a wedge-shaped detachable sound-absorbing barrier for rail transit in view of the deficiencies of the prior art; its technical solution is as follows:

[0009] A wedge-shaped detachable sound-absorbing barrier for rail transit, including a barrier housing. The right end of the barrier housing is set in an open form, and an installation partition is also arranged inside the barrier housing. The area between the installation partition and the left side wall of the barrier housing is set as the installation area, and the area on the right side of the installation partition is set as the barrier area. A planar sound-absorbing barrier is correspondingly installed in the barrier area. The planar sound-absorbing barrier is correspondingly fixed on the installation partition, and evenly spaced circular installation holes are arranged on the planar sound-absorbing barrier. Removable wedge-shaped sound-absorbing barriers are correspondingly arranged in the installation holes.

[0010] Furthermore, the wedge-shaped sound-absorbing barrier includes a cylindrical base and a conical tip. The cylindrical base is correspondingly arranged in the installation hole, and the conical tip extends out accordingly. The conical tip is located outside the planar sound-absorbing barrier.

[0011] Furthermore, installation holes are also arranged on the installation partition. The positions of the installation holes on the installation partition are the same as those of the installation holes on the planar sound-absorbing barrier. The cylindrical base of the wedge-shaped sound-absorbing barrier passes through the installation holes on the installation partition and extends into the installation area.

[0012] Furthermore, a driving motor is horizontally installed on the left side wall of the barrier housing. The main shaft of the driving motor extends into the installation area, and a rotating gear is installed at the shaft end. Another rotating gear is correspondingly meshed and installed on the rotating gear, and an integral rotating boss is correspondingly arranged on each rotating gear.

[0013] The rotating boss is concentric with the rotating gear. The outer diameter of the rotating boss is smaller than that of the rotating gear. The position of the rotating boss corresponds to the position of each installation hole on the installation partition, and the size of the rotating boss is adapted to the size of the installation hole. The rotating boss correspondingly extends into the installation hole on the installation partition. The wedge-shaped sound-absorbing barrier is correspondingly detachably installed on the rotating boss.

[0014] When the rotating motor is started, it drives the rotation of the rotating motor accordingly, and the other meshed and installed rotating motors are also driven to rotate, thereby driving the rotating boss and the wedge-shaped sound-absorbing barrier on the rotating boss to rotate in the installation hole.

[0015] Furthermore, a pin is horizontally installed on each rotating boss. The cylindrical base of the wedge-shaped sound-absorbing barrier is correspondingly inserted on the pin, so that the wedge-shaped sound-absorbing barrier can be correspondingly detached.

[0016] Furthermore, the cylindrical base of the wedge-shaped sound absorption barrier is of the same thickness as that of the planar sound absorption barrier, and the bottom of the conical tip is flush with the end face of the planar sound absorption barrier; and two symmetric vane plates are provided on the conical tip, and the bottom ends of the vane plates are correspondingly close to the end face of the planar sound absorption barrier; when the wedge-shaped sound absorption barrier rotates, the vane plates are correspondingly driven to rotate; and the vane plates on adjacent conical tips do not interfere with each other.

[0017] Furthermore, the mounting holes on the planar sound absorption barrier and the mounting partition are both arranged in five rows and five columns, and the position and number of the rotating gears are correspondingly set. Two adjacent rotating gears in each row and each column are meshed and installed to form a matrix gear, and at least one driving motor is provided.

[0018] Furthermore, the rotating gears are correspondingly installed on the inner wall of the barrier housing through bearing members, so as to fix the rotating gears in the installation area.

[0019] Beneficial effects: The present invention has the following beneficial effects:

[0020] 1) In the present invention, mounting holes are provided on the planar sound barrier, and wedge-shaped sound barriers are correspondingly arranged in the mounting holes. The wedge-shaped sound barrier is composed of a cylindrical base and a conical tip. The thickness of the cylindrical base is the same as that of the planar sound barrier. After being arranged in the mounting holes, the conical tips just correspondingly protrude. Then a matrix-type conical tip structure is formed on the planar sound barrier. When sound waves rush in, the sound waves are blocked and separated by the conical tips, and after collision and reflection, they are absorbed by the planar sound barrier and the character-shaped tips. Compared with the traditional planar sound absorption barrier, the sound absorption efficiency and quality can be significantly improved.

[0021] 2) In the present invention, the wedge-shaped sound barrier can be directly placed in the mounting holes, and the structure is reasonably arranged; and it is also convenient to disassemble and replace. When replacement is needed, it can be directly removed from the mounting holes, and then a new wedge-shaped sound barrier can be replaced.

[0022] 3) In the present invention, if there is a lot of dust on the conical tips, the wedge-shaped sound absorption barrier can be driven to rotate by the rotating gears, and the dust on the conical tips can be cleaned by rotation, so as to improve the sound absorption effect; and it does not affect the detachable installation of the wedge-shaped sound barrier, and it can also be conveniently disassembled for replacement, which is very convenient.

[0023] 4) Two symmetric vanes are also provided on the conical tip of the device. When the conical tip rotates, the vanes will also rotate simultaneously. The design of the vanes has two functions. One is that when rotating, it can drive the air flow and generate turbulent flow, so that the dust on the conical tip can be more easily cleaned off. The other is that the bottom of the vane is closely attached to the end face of the planar sound barrier. When the vane rotates, it will also clean the dust at the end face of the planar sound barrier. After cleaning the covered dust, the sound absorption effect can be effectively improved, and the structural setting is very reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS

[0031] The present invention will be further clarified below in conjunction with the drawings and specific embodiments. These embodiments are implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0032] Such as Figure 1 and Figure 2As shown in the figure, a wedge-shaped detachable sound-absorbing barrier for rail transit includes a barrier housing 1. The right end of the barrier housing 1 is open, and an installation partition 2 is also provided inside the barrier housing 1. The area between the installation partition 2 and the left side wall of the barrier housing 1 is set as an installation area 3, and the area on the right side of the installation partition 2 is set as a barrier area. A planar sound-absorbing barrier 4 is correspondingly installed in the barrier area. The planar sound-absorbing barrier 4 is fixedly installed on the installation partition 2, and evenly spaced circular installation holes 5 are provided on the planar sound-absorbing barrier 4. Removable wedge-shaped sound-absorbing barriers 6 are correspondingly arranged in the installation holes 5.

[0033] The wedge-shaped sound-absorbing barrier 6 includes a cylindrical base 61 and a conical tip 62. The cylindrical base 61 is correspondingly arranged in the installation hole 5, and the conical tip 62 extends out accordingly. The conical tip 62 is located outside the planar sound-absorbing barrier 4.

[0034] The installation partition 2 is also provided with installation holes 5, and the positions of the installation holes 5 on the installation partition 2 are the same as those of the installation holes 5 on the planar sound-absorbing barrier 4. The cylindrical base 61 of the wedge-shaped sound-absorbing barrier 6 passes through the installation holes 5 on the installation partition 2 and extends into the installation area 3.

[0035] As Figure 3 and Figure 4 shown in the figure, a driving motor 7 is also horizontally installed on the left side wall of the barrier housing 1. The main shaft of the driving motor 7 extends into the installation area 3, and a rotating gear 8 is installed at the shaft end. Another rotating gear 8 is correspondingly meshed and installed on the rotating gear 8, and an integral rotating boss 9 is correspondingly arranged on each rotating gear 8.

[0036] The rotating boss 9 and the rotating gear 8 are concentrically arranged. The outer diameter of the rotating boss 9 is smaller than the outer diameter of the rotating gear 8, and the position of the rotating boss 9 corresponds to the position of each installation hole 5 on the installation partition 2. The size of the rotating boss 9 is adapted to the size of the installation hole 5, and the rotating boss 9 correspondingly extends into the installation hole 5 on the installation partition 2. The wedge-shaped sound-absorbing barrier 6 is correspondingly detachably installed on the rotating boss 9.

[0037] When the rotating motor is started, it drives the rotation of the rotating motor accordingly, and the other meshed and installed rotating motors are also driven to rotate, thereby driving the rotating boss 9 and the wedge-shaped sound-absorbing barrier 6 on the rotating boss 9 to rotate in the installation hole 5.

[0038] As Figure 5 and Figure 6 shown in the figure, a pin 10 is horizontally installed on each rotating boss 9. The cylindrical base 61 of the wedge-shaped sound-absorbing barrier 6 is correspondingly inserted on the pin 10, so that the wedge-shaped sound-absorbing barrier 6 can be correspondingly detached.

[0039] The cylindrical base 61 of the wedge-shaped sound-absorbing barrier 6 is of the same thickness as the planar sound-absorbing barrier 4, and the bottom of the conical tip 62 is flush with the end face of the planar sound-absorbing barrier 4; moreover, two symmetrical vane plates 11 are provided on the conical tip 62, and the bottom ends of the vane plates 11 are correspondingly closely attached to the end face of the planar sound-absorbing barrier 4; when the wedge-shaped sound-absorbing barrier 6 rotates, the vane plates 11 are correspondingly driven to rotate; and the vane plates 11 on adjacent conical tips 62 will not interfere with each other.

[0040] The mounting holes 5 on the planar sound-absorbing barrier 4 and the mounting partition 2 are both arranged in five rows and five columns, and the positions and quantities of the rotating gears 8 are correspondingly set. Two adjacent rotating gears 8 in each row and each column are meshed and installed to form a matrix gear, and at least one driving motor 7 is provided.

[0041] The rotating gears 8 are correspondingly installed on the inner wall of the barrier housing 1 through bearing members 12, thereby fixing the rotating gears 8 in the installation area 3.

[0042] The specific working process and principle of this device are as follows: In this device, the planar sound barrier is normally fixed on the mounting partition and used as a sound-absorbing barrier. Mounting holes are provided on the planar sound barrier, and the wedge-shaped sound barrier of the present invention is provided with a cylindrical base and a conical tip. The thickness of the cylindrical base is the same as that of the planar sound barrier. After being arranged in the mounting holes, the conical tip just corresponds to protrude, so a matrix-type conical tip structure is formed on the planar sound barrier. When sound waves pour in, the sound waves are blocked and separated by the conical tips, and after collision and reflection, they are absorbed by the planar sound barrier and the character-shaped tips, which can significantly improve the sound absorption efficiency and quality compared with the traditional planar sound-absorbing barrier.

[0043] Moreover, in the present invention, the wedge-shaped sound barrier is placed in the mounting holes, which is very convenient for installation. After installing the planar sound barrier, the wedge-shaped sound barrier can be directly placed in the mounting holes, and the structure is reasonably arranged; and it is also convenient for disassembly and replacement. When replacement is needed, it can be directly removed from the mounting holes, and then a new wedge-shaped sound barrier can be replaced.

[0044] And because the conical tips are exposed outside and are in a tip shape, it is easier to accumulate dust; in the present invention, mounting holes are correspondingly provided on the mounting partition, and rotating gears are correspondingly provided in the installation area and rotating bosses are installed on the rotating gears. The rotating bosses extend into the mounting holes, and pins are provided. The cylindrical base of the wedge-shaped sound barrier itself can extend into the mounting holes, so it can be directly inserted on the pins; and each mounting hole corresponds to a rotating gear, and all the rotating gears are installed in a matrix-type meshing state, and a driving motor is provided to correspondingly drive all the rotating gears to rotate simultaneously.

[0045] Such as Figure 4As shown, after all the gears are meshed and installed, their rotation directions will not be affected and they can rotate simultaneously. Then, if there is a lot of dust on the conical tip, the rotating gears can drive the wedge-shaped sound barrier to rotate, and the dust on the conical tip can be removed by rotation, improving the sound absorption effect.

[0046] Moreover, the above design will not affect the detachable installation of the wedge-shaped sound barrier, and it can also be easily disassembled and replaced, which is very convenient.

[0047] In addition, two symmetric vane plates are provided on the conical tip of the device. When the conical tip rotates, the vane plates will also rotate simultaneously. The design of the vane plates has two functions. One is that when rotating, it can drive the air flow and generate turbulence, so that the dust on the conical tip will be more easily removed. The other is that the bottom of the vane plate is closely attached to the end face of the flat sound barrier. When the vane plate rotates, it will also clean the dust at the end face of the flat sound barrier. After the covered dust is removed, the sound absorption effect can be effectively improved, and the structural setting is very reasonable.

[0048] The rotation speed of the rotating gears in the device can be set according to the actual situation, and it should not be too fast and can be adjusted appropriately. At the same time, it can also rotate during sound absorption to increase the refraction of sound waves.

[0049] The above specific implementation manner is only a preferred embodiment of the present invention and is not used to limit the implementation and scope of the claims of the present invention. All equivalent changes and modifications made based on the content of the patent protection scope of the present invention should be included within the scope of the patent application of the present invention.
