Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, and in particular to a noise pollution barrier. Background Technology

[0002] Sound barriers are mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources. They are divided into reflective sound barriers that are purely sound-insulating and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. Sound barriers are wall-like structures set up beside railways and highways to reduce the impact of traffic noise on nearby residents. Sound barriers are also called noise walls. They are facilities inserted between the sound source and the receiver to give the sound wave propagation a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. Such facilities are called sound barriers.

[0003] For example, patent document CN216551639U discloses a noise pollution barrier, comprising multiple H-beams spaced apart on the ground. A limiting plate is connected to the top of each H-beam, and rubber blocks are connected to both ends of the bottom surface of the limiting plate. Installation openings are provided at both ends of the bottom side of one flange of each H-beam. Several sound-insulating panels are arranged vertically between every two H-beams, with each panel abutting against the others. A clamping plate is connected to both sides of each sound-insulating panel, the length of which is less than the height of the installation opening. The upper sound-insulating panel is slidably connected to the groove formed by the flange and web of the H-beam via the clamping plate, with the topmost clamping plate abutting against the rubber blocks. The clamping plate on the bottom sound-insulating panel is connected to the flange of the H-beam via screws and nuts. This utility model has a reasonable structural design and can effectively improve installation efficiency. In existing technologies, noise pollution barriers are mostly installed in open-air environments and are usually more than 2 meters high. This results in the noise pollution barriers bearing a lot of force in windy weather, which greatly reduces their service life over time. In addition, in existing technologies, the sound insulation panels are mostly fixed directly to the columns by sliding grooves, which makes installation and maintenance inconvenient. Therefore, a noise pollution barrier that is easy to install and maintain and is not afraid of strong winds is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a noise pollution barrier to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A noise pollution barrier includes two parallel support structures. Each support structure comprises several stacked support columns, with a base assembly at the bottom of each support column. Several assembly mechanisms are arranged between the two parallel support columns. Each assembly mechanism includes a fixing frame bolted to the support column. A bearing frame is rotatably connected to the bottom of the fixing frame, and a sound insulation plate is installed on the bearing frame. Two symmetrically arranged connecting rods are rotatably connected to both sides of the bearing frame. A lifting rod is slidably connected inside the support column, and the other end of the connecting rod is rotatably connected to the lifting rod. A power mechanism is fixedly connected to the top of the uppermost support column. The power mechanism includes an electric telescopic rod, the output end of which is fixedly connected to the lifting rod. A wind detection component is arranged above the electric telescopic rod.

[0007] Preferably, the upper and lower ends of the support column are fixedly connected to connecting plates, and several stacked support columns are connected by bolts to the connecting plates. The rear side of the support column is rotatably connected to an inclined support.

[0008] Preferably, the base assembly includes a bottom bracket placed on the ground, the bottom bracket being bolted to a connecting plate at the bottom of the lowest support column, and two support blocks being bolted to the front and rear sides of the support column. The support blocks are L-shaped, and the bottom of the support blocks are bolted to the bottom bracket. Several fixing nails are slidably connected to the bottom bracket.

[0009] Preferably, the inner side of the support frame is provided with a sliding groove, the sound insulation board is placed in the sliding groove of the support frame, and a limit plate is bolted to the support frame. One side of the limit plate can abut against the sound insulation board and limit the sound insulation board.

[0010] Preferably, the top of the uppermost support column is bolted to a top bracket, the top of the top bracket is fixedly connected to an integrated bracket, the integrated bracket is fixedly connected to an electric telescopic pole, the wind power detection component is installed on the integrated bracket, and a solar panel is fixedly connected to the top of the integrated bracket.

[0011] Preferably, the upper and lower lifting rods are fixedly connected by a connecting sleeve, and two springs are fixedly connected to the upper and lower ends of the lifting rods, with the other end of the springs fixedly connected to the inside of the support column.

[0012] The beneficial effects are as follows: by setting up the fixed frame and the support frame, the sound insulation panel can be tilted. When the wind force detection component senses that the wind force is strong, the electric telescopic rod is activated. The electric telescopic rod drives the lifting rod to rise and fall. The lifting rod drives the connecting rod to move. The connecting rod drives the support frame to open. In this way, the wind pressure on the sound barrier is reduced by tilting the sound insulation panel when the wind force is strong. In addition, the separate opening of the support frame makes it easier for staff to install and maintain the sound insulation panel.

Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a noise pollution barrier includes two parallel support structures. Each support structure comprises several stacked support columns 101, with a base assembly at the bottom of each column. Several assembly mechanisms are arranged between the two parallel support columns 101. Each assembly mechanism includes a fixing frame 201 bolted to the support column 101. A bearing frame 202 is rotatably connected to the bottom of the fixing frame 201, and a sound-insulating plate 203 is mounted on the bearing frame 202. Two symmetrically arranged connecting rods 205 are rotatably connected to both sides of the bearing frame 202. A lifting rod 206 is slidably connected inside each support column 101, and the other end of each connecting rod 205 is rotatably connected to the lifting rod 206. A power mechanism is fixedly connected to the top of the uppermost support column 101. The power mechanism includes an electric telescopic rod 303, the output end of which is connected to the lifting rod 206. A wind detection component 305 is installed above the electric telescopic pole 303. When the wind is strong, the wind detection component 305 senses the wind intensity and generates an electrical signal to activate the electric telescopic pole 303. The electric telescopic pole 303 drives the lifting rod 206 to rise and fall. The lifting rod 206 drives the connecting rod 205 to move, and the connecting rod 205 drives the support frame 202 to rotate. The support frame 202 drives the sound insulation panel 203 to open, allowing wind to pass through the gap between the support frame 202 and the fixed frame 201. This reduces the force on the sound barrier in windy weather, thereby extending the service life of the sound barrier. In addition, when the sound barrier is being maintained, the sound insulation panel 203 can also be opened by the electric telescopic pole 303, allowing staff to replace a single sound insulation panel 203, which greatly facilitates the maintenance of the sound barrier.

[0028] The upper and lower ends of the support column 101 are fixedly connected to the connecting plates 103. Several stacked support columns 101 are bolted together by the connecting plates 103. An inclined support 102 is rotatably connected to the rear side of the support column 101. The base assembly includes a bottom bracket 104 placed on the ground. The bottom bracket 104 is bolted to the connecting plate 103 at the bottom of the lowest support column 101. Two support blocks 105 are bolted to the front and rear sides of the support column 101. The support blocks 105 are L-shaped and their bottoms are bolted to the bottom bracket 104. Several fixing nails 106 are slidably connected to the bottom bracket 104. The workers placed the bottom bracket 104 in the predetermined installation position, and then used fixing nails 106 to fix the bottom bracket 104. The support column 101 was fixed to the bottom bracket 104 with bolts. The bottom bracket 104 was then fixed to the front and back of the support column 101 with bolts. The bottom bracket 104 can enhance the support strength of the support column 101. Then, another support column 101 was fixed to the support column 101 with bolts. The top bracket 301 was fixedly connected to the top of the other support column 101. Several fixing brackets 201 were placed between the two horizontally set support columns 101 and fixed with bolts.

[0029] The inner side of the support frame 202 is provided with a sliding groove. The sound insulation plate 203 is placed in the sliding groove of the support frame 202. A limiting plate 204 is bolted to the support frame 202. One side of the limiting plate 204 can abut against the sound insulation plate 203 and limit the sound insulation plate 203. The sound insulation plate 203 is placed in the support frame 202, and then the limiting plate 204 is placed on the support frame 202 to limit the sound insulation plate 203 and is fixed by bolts.

[0030] The top of the uppermost support column 101 is bolted to a top bracket 301. An integrated bracket 302 is welded to the top of the top bracket 301. The integrated bracket 302 is bolted to the electric telescopic pole 303. A wind detection component 305 is installed on the integrated bracket 302. A solar panel 304 is fixedly connected to the top of the integrated bracket 302. The solar panel 304 uses solar energy to generate electricity to power the electric telescopic pole 303.

[0031] The upper and lower lifting rods 206 are fixedly connected by a connecting sleeve 208. Two springs 207 are fixedly connected to the upper and lower ends of the lifting rods 206. The other end of the springs 207 is fixedly connected to the inside of the support column 101. The springs 207 ensure that the lifting rods 206 are reset inside the support column 101. The connecting sleeve 208 ensures that the upper and lower lifting rods 206 can move synchronously.

[0032] Working principle: The operator places the bottom bracket 104 in the predetermined installation position, and then uses fixing nails 106 to fix the bottom bracket 104. The support column 101 is fixed to the bottom bracket 104 with bolts. The bottom bracket 104 is then fixed to the front and rear of the support column 101 with bolts. The bottom bracket 104 can enhance the support strength of the support column 101. Then, another support column 101 is fixed to the support column 101 with bolts. The top bracket 301 is fixedly connected to the top of the other support column 101. Several fixing brackets 201 are placed between the two horizontally set support columns 101 and fixed with bolts. The sound insulation panel 203 is placed in the bearing frame 202. Then, the limiting plate 204 is placed on the bearing frame 202 to limit the sound insulation panel 203. The sound barrier is fixed in place with bolts. When the wind is strong, the wind detection component 305 senses the wind intensity and generates an electrical signal to activate the electric telescopic rod 303. The electric telescopic rod 303 drives the lifting rod 206 to rise and fall. The lifting rod 206 drives the connecting rod 205 to move, and the connecting rod 205 drives the support frame 202 to rotate. The support frame 202 drives the sound insulation panel 203 to open, and the wind passes through the gap between the support frame 202 and the fixed frame 201. This can reduce the force on the sound barrier in windy weather, thereby extending the service life of the sound barrier. In addition, when the sound barrier is being maintained, the sound insulation panel 203 is also opened by the electric telescopic rod 303, and the staff can replace a sound insulation panel 203 individually, which greatly facilitates the maintenance of the sound barrier.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
