Description

Technical Field

[0001] The present invention relates to a barrier used in road protection, and more specifically, to a municipal road barrier used in municipal road protection and having the functions of sound absorption and automobile exhaust absorption. Background Art

[0002] Existing isolation products are usually made of steel structures or cement piles when used for road protection. Their main function is to isolate and protect the left and right channels on a two-way road so that they can each drive on their own designated road, preventing vehicles from changing lanes or driving in the opposite direction at will and causing safety accidents.

[0003] It can be seen from this that the existing isolation barriers only have a protective function and do not have a sound-absorbing function. When vehicles are traveling on municipal roads, especially urban municipal roads, a lot of noise is usually generated due to the large number of vehicles. The existing isolation barriers with sound insulation effects used on highways or railways are relatively high and their structures are not suitable for installation in urban roads, and cannot be used on urban road isolation barriers.

[0004] The existing technology for sound-absorbing or sound-isolating barriers on municipal roads mainly includes columnar barriers from foreign companies, which cost about 1,800 euros per meter; and barrier structures used on some municipal roads in my country, which cost about 1,800 yuan per meter. Because the sound-absorbing effect of both can only reach about 50%, and the price is expensive, they cannot be promoted in the use of municipal roads, which leads to the fact that most of the existing municipal barriers still have only protective functions, and have no isolation or sound-absorbing effects. ; Summary of the invention

[0005] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages which will be described hereinafter.

[0006] Another object of the present invention is to provide a municipal road isolation fence with a sound-absorbing function, which can make its material structure loose and porous through the selection of materials, so that the hole walls can absorb or vibrate the noise respectively, increase the time that the noise stays inside the material, so as to absorb a certain amount of noise, thereby ensuring that the noise absorption effect can reach about 30%; at the same time, by arranging the multiple holes in the material to penetrate so that it is connected with the adjacent holes, thereby forming an integrally connected sound-absorbing hole or cavity inside the material, so that through the connected holes, the noise can be further transmitted and maintained to each other when it is absorbed or vibrated in the hole, and the noise stays in the hole is increased by 2-3.5 times, thereby making its sound absorption effect reach 80% or more; at the same time, due to the selection of materials, its price is controlled between 210-300 per meter, which greatly controls the installation cost and is conducive to promotion in municipal road construction.

[0007] In order to achieve these purposes and other advantages according to the present invention, a municipal road isolation fence with sound absorption function is provided, comprising:

[0008] Coordinated with the direction of travel of the city roads, multiple porous sound-absorbing panels are formed as sound-absorbing isolation barriers on both sides of the road;

[0009] Each of the porous sound-absorbing panels has a plurality of holes, and each hole is configured to be through-shaped to communicate with the adjacent holes, thereby forming a sound-absorbing cavity and a self-cleaning through hole of an integral structure in each of the porous sound-absorbing panels.

[0010] Preferably, in a two-way urban road, the isolation fence is configured as a double-layer structure in the middle of the road to match the extension direction of the road, and there is a predetermined distance between the two to form a sound-absorbing channel matching the two-way road.

[0011] Preferably, the porous sound absorbing panels on both sides of the sound absorbing channel are arranged to be staggered with respect to each other, so that the double-layered isolation fence is in a closed structure relative to the roads on both sides.

[0012] Preferably, the height of the porous sound absorbing board on one side of the sound absorbing channel is configured to be smaller than the height of the porous sound absorbing board on the other side, so as to form a plurality of air inlets between the lower porous sound absorbing board and the ground through the height difference;

[0013] The air inlets are staggered and arranged on both sides of the sound absorption channel, so that a two-way air passage that can move toward the end of the sound absorption channel is formed through the air inlets on the two-way road.

[0014] Preferably, the porous sound absorbing board is configured to have a plurality of longitudinal grooves perpendicular to the road surface on the surface facing the road side, so as to form a sound absorbing surface with longitudinal corrugations on the surface of the porous sound absorbing board, thereby greatly increasing the effective sound absorbing area.

[0015] Preferably, the porous sound absorbing board is configured to have a plurality of transverse grooves parallel to the road surface on the surface facing away from the road, so as to form an adsorption surface with transverse corrugations on the other surface of the porous sound absorbing board.

[0016] Preferably, it further comprises a column matched with each of the porous sound-absorbing panels;

[0017] Each of the porous sound-absorbing panels is provided with at least one steel belt that can extend in a predetermined direction on the side opposite to the road;

[0018] Each of the porous sound-absorbing panels is fixed on a column by a steel belt, thereby forming a barrier with a protective function on both sides of the road.

[0019] Preferably, the steel belt is configured as a corrugated or spiral structure.

[0020] Preferably, the two ends of the steel belt are configured to be curved to form a fixing ring that matches the column.

[0021] Preferably, each of the porous sound-absorbing panels is provided with a mounting groove matched with a steel belt, and the width of the steel belt is configured to be 10-20 cm.

[0022] The present invention includes at least the following beneficial effects: first, the present invention can make its material structure loose and porous through the selection of materials, so that the pore walls can absorb or vibrate the noise respectively, increase the time that the noise stays inside the material, so as to absorb a certain amount of noise, thereby ensuring that the noise absorption effect can reach about 30%; at the same time, by arranging the multiple holes in the material to penetrate so that it is connected with the adjacent holes, thereby forming an integrally connected sound-absorbing hole or cavity inside the material, so that through the connected holes, the noise can be further transmitted and maintained to each other when it is absorbed or vibrated in the hole, and the time that the noise stays in the hole is increased by 2-3.5 times, thereby making the sound absorption effect reach 80% or more; at the same time, due to the selection of materials, its price is controlled between 210 and 300 per meter, which greatly controls the installation cost and is conducive to its promotion in municipal road construction.

[0023] Secondly, the sound-absorbing holes of the present invention can absorb part of the dust or powder in the air while absorbing sound, and have a certain adsorption capacity. Moreover, because the sound-absorbing holes are through-holes, the dust or powder in the sound-absorbing holes can be taken away in real time by the fluidity of water on rainy days or when municipal workers sprinkle water or spray to clean municipal facilities. Therefore, the sound-absorbing holes have self-cleaning properties and can ensure that their sound absorption and adsorption effects are not affected.

[0024] Thirdly, the isolation fence of the present invention, due to the selection of materials, can be broken relatively promptly if it encounters a collision during isolation and protection, and its reaction force can be greatly reduced, and it will not rebound to the middle of the road to cause secondary damage.

[0025] Fourthly, the present invention provides a ductile steel belt on the isolation fence, so that after the isolation fence is broken, the steel belt can be used to intercept the vehicle to prevent it from running out of the road and causing a safety accident, thereby having higher safety.

[0026] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0032] It should be understood that terms such as “having”, “including” and “comprising” used herein do not specify the existence or addition of one or more other elements or combinations thereof.

[0033] Figure 1 The embodiment of a municipal road barrier with sound absorption function according to the present invention is shown, which includes:

[0034] In coordination with the direction of travel of the urban road, a plurality of porous sound-absorbing panels 1 are formed as sound-absorbing isolation barriers on both sides of the road. Cement-based sound-absorbing panels or lightweight high-strength cement sound-absorbing panels can be preferably selected. Through the setting of the material, it can absorb most of the volume when the sound is transmitted inside it through its loose and porous texture in the application, and the design of the material through which it passes can make it have the effect of absorbing 30% of the noise; at the same time, when a collision occurs, the selection of its structure can make it break in time to prevent the force it gives to the vehicle from pushing the vehicle back to the middle of the road and causing secondary damage;

[0035] Each of the porous sound-absorbing panels has a plurality of holes 2, and each of the holes is configured to be through-shaped to communicate with the adjacent holes, thereby forming a sound-absorbing cavity (not shown) and a self-cleaning through hole (not shown) of an integral structure in each of the porous sound-absorbing panels. The connection of the holes in this solution enables each hole to form a through hole in space, thereby connecting each hole to form a sound-absorbing hole or cavity. After receiving noise, the sound-absorbing cavity can absorb and transmit the noise through each section of the sound-absorbing cavity, while continuously attenuating the noise to achieve a sound-absorbing effect.

[0036] At the same time, by connecting the holes, a through hole can be formed in space for cleaning the holes, so that it can absorb dust and / or dust generated by vehicles or other mechanisms in the air while absorbing sound, and can be cleaned by flushing with rainwater or flushing with a clean water pipe in the hands of sanitation workers on rainy days. While having a good sound absorption effect, it also has adsorption and self-cleaning functions, and has the advantages of good adaptability and stronger functions. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0037] like Figure 1 As shown, in another example, in a two-way urban road, the isolation fence is configured as a double-layer structure in the middle of the road that matches the extension direction of the road, and there is a predetermined distance between the two, so as to form a sound-absorbing channel 3 that matches the two-way road. This scheme is used to set the isolation fence in the middle of the road into a double-layer structure, and the two are spaced a predetermined distance such as 5-15cm, preferably 10cm, so that when the volume passing through the sound-absorbing board is transmitted again, the sound-absorbing channel is formed by the gap between the two to absorb the noise for the second time, further reducing the noise level, so that it can absorb 70-80% of the noise generated by the vehicle, which has the advantages of good implementation effect, strong operability and strong adaptability. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacement and / or modification can be made according to user needs.

[0038] like Figure 1 As shown, in another example, the porous sound-absorbing panels on both sides of the sound-absorbing channel are configured to be staggered with each other, so that the double-layer isolation fence is in a closed structure relative to the roads on both sides. This solution can prevent the gap between the two horizontally arranged double-layer porous sound-absorbing panels due to installation on the columns, so the sound absorption effect is better, and it has the advantages of good implementation effect and good product sound absorption effect. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacement and / or modification can be made according to user needs.

[0039] like Figure 2As shown, in another example, the height of the porous sound-absorbing board on one side of the sound-absorbing channel is configured to be smaller than the height of the porous sound-absorbing board on the other side, so that a plurality of air inlets 4 are formed between the lower porous sound-absorbing board and the ground through the height difference. The height difference can be set to ensure that the tops of the porous sound-absorbing boards on both sides are flush after installation, and the height difference is also used to ensure that one of the sound-absorbing boards has a predetermined distance from the ground, so that the gas generated by the moving vehicle can smoothly enter the sound-absorbing channel, so as to absorb the dust and exhaust gas generated by the vehicle running in the air;

[0040] Among them, each of the air inlets is staggered and arranged on both sides of the sound absorption channel, and then a two-way airway (not shown) that can move toward the end of the sound absorption channel is formed through each air inlet on the two-way road, which can adapt to the use needs of the two-way road, so that the gas with relative pressure is generated during the movement of the car in the two-way road, so that under the action of positive and negative pressure, the gas mixed with dust or dust is pushed into the airway, and the porous material of the porous sound-absorbing board is used to actively push the dust or dust in the air into the hole through the action of air pressure, so as to achieve active adsorption of dust or dust in the air. Compared with the existing autonomous adsorption through materials, its adsorption effect can be enhanced by 2-3 times. This scheme has the advantages of good implementation effect, strong operability, good adaptability and strong stability. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0041] like Figure 3 As shown, in another example, the porous sound-absorbing board is configured to have a plurality of longitudinal grooves 5 perpendicular to the road surface on the surface facing the road, so as to form a sound-absorbing surface with longitudinal corrugations on the surface of the porous sound-absorbing board. This scheme is adopted to enhance its sound-absorbing surface through the design of its structure, thereby significantly enhancing its sound-absorbing effect, and has the advantages of good implementability, strong adaptability and good stability. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0042] like Figure 3As shown, in another example, the surface of the porous sound-absorbing board facing away from the road is configured to have a plurality of transverse grooves 6 parallel to the road surface, so as to form an adsorption surface with transverse corrugations on the other surface of the porous sound-absorbing board. This scheme is adopted to enhance its adsorption surface by designing its surface structure, and at the same time, through its wave-like structure, the adsorption effect can be significantly enhanced under the action of air pressure, which has the advantages of good implementation effect, strong adaptability and good stability. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacement and / or modification can be made according to user needs.

[0043] like Figure 1 , 4 As shown, in another example, it further includes a column 7 matched with each of the porous sound-absorbing panels, which is used to fix the porous sound-absorbing panels to form a separation fence;

[0044] Each of the porous sound-absorbing panels is provided with at least one steel belt 8 that can be extended in a predetermined direction on the side opposite to the road surface. By providing an extendable steel belt on the back of the porous sound-absorbing panel, when the porous sound-absorbing panel is broken, the steel belt is extended to form an arc-shaped structure to intercept the vehicle and prevent it from running off the road surface or running out of the road.

[0045] Each of the porous sound-absorbing panels is fixed on the pillars through steel belts, thereby forming a barrier with a protective function on both sides of the road. The barrier is fixed on the pillars through the cooperation of the steel belts. Compared with the steel structure barrier in the prior art, it does not need to set up a mounting seat or mounting groove. This scheme has the advantages of good implementation effect, strong operability, good stability and good adaptability. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0046] In another example, the steel belt is configured as a corrugated or spiral structure. This solution allows the steel belt to be extended through the corrugated structure or the elastic force of the spiral structure when the porous sound-absorbing board is broken. Under the force of the vehicle, an arc-shaped structure is formed to intercept the vehicle and prevent it from running off the road or out of the road. It has the advantages of good implementation effect, strong operability and good adaptability. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0047] like Figure 4As shown, in another example, the two ends of the steel belt are configured to be curved to form a fixing ring 9 that matches the column. This solution allows the fixing ring to have a gap, which is convenient for installation and adaptability to installation columns of different sizes, and has the advantages of good implementation effect, stability, and convenient installation. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0048] like Figure 4 As shown, in another example, each of the porous sound-absorbing panels is provided with a mounting groove that matches the steel belt, and the width of the steel belt is configured to be 10-20 cm. Each of the porous sound-absorbing panels is provided with a mounting groove 10 that matches the steel belt, and the width of the steel belt is configured to be 10-20 cm, which is used to ensure the stability of the matching with the porous sound-absorbing panel after installation, and at the same time ensure that the pulling force when intercepting the vehicle meets the requirements and will not break. The adoption of this solution makes the matching between the steel belt and the porous sound-absorbing panel more stable, and at the same time allows it to be assembled on site, which is convenient for transportation and management, and has the advantages of good stability and good adaptability. Moreover, this method is only an illustration of a preferred example, but is not limited to this. When implementing the present invention, appropriate replacements and / or modifications can be made according to user needs.

[0049] The number of devices and processing scales described here are used to simplify the description of the present invention. The application, modification and variation of the municipal road isolation fence with sound absorption function of the present invention will be obvious to those skilled in the art.

[0050] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
