Description

Technical Field

[0001] This utility model relates to the field of fully enclosed sound barrier technology, and in particular to a novel fully enclosed sound barrier capable of eliminating virtual sound sources at the top. Background Technology

[0002] Sound barriers are primarily used for noise reduction along highways, expressways, elevated roads, and other noise sources. They are divided into reflective sound barriers (purely for sound insulation) and composite sound barriers (combining sound absorption and insulation), the latter being a more effective sound insulation method. Sound barriers are wall-like structures erected alongside railways and highways to reduce the impact of traffic noise on nearby residents. They are also called sound barriers. A sound barrier is a structure inserted between a sound source and a receiver that significantly attenuates sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located.

[0003] A search revealed a novel fully enclosed sound barrier with publication number CN208701527U that can eliminate virtual sound sources at the top. The barrier includes a roadbed, two support plates, and sound-absorbing barrier panels fixedly installed on one side of each plate. Several first hanging rings are connected to several second hanging rings via connecting lines. Several top noise reduction devices are fixedly installed at the bottom of both the first and second top plates. Each noise reduction plate has a noise reduction cavity inside. Two sliding grooves are slidably connected to the sides of a sliding plate. This novel fully enclosed sound barrier eliminates virtual sound sources at the top by using hanging rods to support the first and second top plates. The installation angle of the first and second top plates can be changed by rotating the mounting plate. The top noise reduction devices eliminate virtual sound sources at the top, and the sliding plate position can be adjusted according to different installation environments, resulting in superior noise reduction performance.

[0004] When the device in the disclosed patent is in use, each top plate has multiple noise reduction plates, and each noise reduction plate has multiple sliding plates. Each noise reduction plate needs to slide its sliding plate individually to change the cavity structure. For long-distance sound barriers, adjusting the multiple sliding plates of multiple noise reduction plates one by one is time-consuming and labor-intensive. Utility Model Content

[0005] In response to the technical problems in existing patents, where each top plate has multiple noise reduction panels, each noise reduction panel has multiple sliding plates, and each noise reduction panel requires individual sliding of the sliding plate to change the cavity structure, making it time-consuming and labor-intensive to adjust multiple sliding plates of multiple noise reduction panels piece by piece for long-distance sound barriers, this utility model provides a novel fully enclosed sound barrier that can eliminate virtual sound sources at the top.

[0006] The technical solution adopted in this utility model is: a novel fully enclosed sound barrier capable of eliminating virtual sound sources at the top, comprising:

[0007] Multiple brackets, each bracket having a soundproof top plate inside;

[0008] Multiple noise reduction mechanisms are provided, with each noise reduction mechanism corresponding to one of the brackets. Each noise reduction mechanism includes two sets of noise reduction components fixed to the bottom end of the soundproof top plate. Each noise reduction component includes a mounting ring connected to the bottom end of the soundproof top plate, multiple first and second noise reduction plates arranged in a circular array on the side of the mounting ring, a sliding plate slidably engaged between the first and second noise reduction plates, a threaded rod threadedly engaged with the sliding plate, and a transmission rod rotatably engaged with the multiple threaded rods on the side of the mounting ring.

[0009] Furthermore, the transmission rod has a first bevel gear at one end extending into the mounting ring, and the threaded rod has a second bevel gear at one end extending into the mounting ring. The first bevel gear meshes with one of the second bevel gears. A first bearing corresponding to the threaded rod is embedded in the side of the mounting ring. A smooth surface is provided on one side of the threaded rod, and one end of the threaded rod is fixed in the first bearing. A second bearing corresponding to the transmission rod is embedded in the side of the threaded rod, and one end of the transmission rod is fixed in the second bearing.

[0010] Furthermore, the upper side of the mounting ring is provided with two connecting plates that are fixedly connected to the soundproof top plate. The bottom end of the soundproof top plate is provided with a drive mechanism for driving the transmission rod to rotate. The drive mechanism includes two transmission shafts fixed to the bottom end of the soundproof top plate, a third bevel gear on the transmission shaft and corresponding to the transmission rod, a fourth bevel gear on the upper end of the transmission rod, a fifth bevel gear on one end of the transmission shaft, and a servo motor on the bottom end of the soundproof top plate. The output end of the servo motor is fixedly connected to one of the transmission shafts. The third bevel gear meshes with the fourth bevel gear, and the two fifth bevel gears mesh with each other.

[0011] Furthermore, the two sets of noise reduction components correspond one-to-one with the two drive shafts. Each set of noise reduction components includes multiple noise reduction components fixed to the bottom end of the soundproof top plate. The threaded rods in the two sets of noise reduction components have opposite thread directions. The soundproof top plate has a V-shaped plate structure. A third bearing is embedded in the side of the connecting plate, and the drive shaft is fixed in the third bearing.

[0012] Furthermore, two sound-absorbing and sound-insulating barrier panels are provided between two adjacent supports, and there is a gap between the inner sides of the two sound-absorbing and sound-insulating barrier panels and the two sides of the sound-insulating top plate. The support is a U-shaped plate structure, and each inner side of the support is provided with a sound-insulating exhaust plate. There is a gap between the bottom surface of the sound-insulating exhaust plate and the sound-insulating top plate. The bottom end of the support is provided with a base.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a threaded rod, a first bevel gear, and a second bevel gear, it is easy to rotate the transmission rod, which drives the first bevel gear and the second bevel gear to mesh, thereby driving the threaded rod to rotate. This, in turn, adjusts the sliding plates of the noise reduction component, improving the convenience of adjusting the sliding plates and reducing the workload of workers. By setting up a drive mechanism, a servo motor drives the transmission shaft to rotate. Through the meshing of two fifth bevel gears, it is easy for the two transmission shafts to rotate synchronously. The transmission shaft drives the third bevel gear and the fourth bevel gear to mesh, which drives all the transmission rods at the bottom of the soundproof top plate to rotate synchronously, thereby driving all the sliding plates at the bottom of the soundproof top plate to slide, improving the efficiency of adjusting the sliding plates.

[0028] Furthermore, the transmission rod 206 extends into the mounting ring 201 and has a first bevel gear 208 at one end, and the threaded rod 205 extends into the mounting ring 201 and has a second bevel gear 209 at one end.
