Description

Technical Field

[0001] This invention relates to the field of urban road noise insulation technology, specifically a modular noise barrier for urban expressways. Background Technology

[0002] A sound barrier is a noise reduction facility primarily used to block direct sound between a sound source and a receiver. By inserting a barrier between the sound source and receiver, it significantly attenuates sound wave propagation, thereby reducing noise impact within a certain area where the receiver is located. Its working principle is mainly based on the reflection, absorption, and diffraction phenomena that occur when sound waves encounter obstacles during propagation. When a sound wave encounters a sound barrier, most of the sound energy is reflected, some is absorbed, and the remaining portion is diffracted, thus reducing the noise intensity at the receiving point. Sound barriers can significantly reduce noise intensity at the receiving point, improving the quality of life for residents. They are widely used on urban expressways and are currently used in urban areas. While existing noise barriers on expressways generally meet daily usage needs, they still have some shortcomings. Firstly, current urban expressway noise barriers require on-site assembly using tools, a cumbersome and complex process that increases labor costs. Secondly, the existing noise barriers have a simple overall structure and poor impact resistance, making them prone to deformation and damage from external impacts, thus affecting their lifespan. Thirdly, existing noise barriers have simple functions and monotonous designs, resulting in poor aesthetics when placed along urban expressways, thus impacting their practicality. Therefore, designing a modular noise barrier for urban expressways is essential. Summary of the Invention

[0010] As a further technical solution of the present invention, an adjusting plate is slidably connected in the buffer bracket, and a buffer spring is provided between the adjusting plate and the buffer bracket. An adjusting rod is rotatably connected to one side of the adjusting plate, and the adjusting rod is threadedly connected to the adjusting sleeve, which is fixedly sleeved in the buffer bracket.

[0011] As a further technical solution of the present invention, an extension frame of an extended energy collection component is fixedly installed on one side of the top of the barrier side plate. The extended energy collection component consists of a pusher ball, a support plate, a fixing frame, an extended power supply, a photovoltaic panel, an indicator light bar, an extension frame, and a pusher cylinder.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: This modular sound barrier for urban expressways utilizes a sliding groove on one side of the barrier base plate to support the docking frame. As the docking frame approaches the barrier base plate along the sliding groove, it presses against the unlocking frame. When the unlocking frame slides to the docking groove, it is pressed tightly into the docking groove under the elastic force of the support spring, thus fixing the docking frame to one side of the barrier base plate. During the laying of the barrier base plate, fixed anchor rods pass through the docking blocks and docking frames on two adjacent sets of barrier base plates to achieve the laying and fixing of the barrier base plate. Subsequently, the connecting plate is sleeved in the second bracket. During the pressing of the connecting plate, it squeezes the locking ball. When the locking ball moves to the locking groove, the locking groove is pressed into the locking groove under the action of the locking spring. Then, the sliding frame is pressed down along the sliding groove. When the limiting ring at one end of the guide rod is sleeved in the sliding frame, the barrier side plate is fixed, and the barrier side plate is then assembled and spliced ​​on the top of the barrier base plate. The splicing process is simple and convenient and does not require additional... Tools are used to reduce on-site installation labor costs. Support rails and buffer brackets provide support for the adjusting slider and the fourth bracket, respectively. The fourth bracket is elastically connected to the adjusting plate through a buffer spring, forming a buffer structure for the barrier. The support angle of the support rod is adjusted by adjusting the position of the adjusting slider and the adjusting plate. When the barrier is impacted by external force, it will rotate around the first bracket. At the same time, the support rod squeezes the buffer spring to buffer the pressure, preventing the barrier from deforming and being damaged by impact, thus extending the service life of the barrier. The set extension frame provides support for the push cylinder, the fixed frame and the photovoltaic panel, expanding the photovoltaic charging function of the barrier and improving space utilization. At the same time, the push cylinders on both sides drive the push steel balls to push the support plate to rotate on the fixed frame, adjusting the position of the photovoltaic panel and ensuring the energy utilization rate of the photovoltaic panel. At the same time, the extended power supply absorbs the energy converted by the photovoltaic panel to power the indicator light strip at night, improving the aesthetics of the barrier after its installation and improving the practicality of the product.

[0018] Working principle: During use, the sliding groove on one side of the barrier base plate 5 is used to support the docking frame 12. As the docking frame 12 moves along the sliding groove towards the barrier base plate 5, it will press against the unlocking frame 14. When the unlocking frame 14 slides to the docking slot 13, the unlocking frame 14 will be pressed tightly into the docking slot 13 under the elastic force of the support spring 15, thereby fixing the docking frame 12 on one side of the barrier base plate 5. During the laying of the barrier base plate 5, the fixed anchor rod 6 passes through the docking blocks 11 and docking frames 12 on the two adjacent sets of barrier base plates 5 to achieve the laying and fixing of the barrier base plate 5. The connecting plate 21 is then fitted into the second bracket 32. During the pressing process, the connecting plate 21 will compress the locking ball 24. When the locking ball 24 moves to the locking slot 27, the locking slot 27 will be pressed into the locking slot 27 under the action of the locking spring 20. Then, the sliding frame 23 is pressed down along the sliding slot 22. When the limiting ring 26 at one end of the guide rod 25 is fitted into the sliding frame 23, the barrier side plate 7 is fixed. Then, the barrier side plate 7 is assembled and spliced ​​on the top of the barrier base plate 5. The splicing process is simple and convenient and does not require the use of additional tools, thereby reducing the current cost. The manual labor cost of field installation; the support rail 33 and the buffer bracket 42 provide support for the adjusting slider 34 and the fourth bracket 37 respectively. The fourth bracket 37 is elastically connected to the adjusting plate 39 through the buffer spring 38 to form the buffer structure of the barrier. The support angle of the support rod 36 is adjusted by adjusting the position of the adjusting slider 34 and the adjusting plate 39. When the barrier is impacted by external force, it will rotate around the first bracket 31. At the same time, the pressure is buffered by the support rod 36 compressing the buffer spring 38, which prevents the barrier from being deformed and damaged by impact, thereby extending the service life of the barrier. Lifespan; The extended frame 49 provides support for the push cylinder 50, the fixed frame 45, and the photovoltaic panel 47, extending the photovoltaic charging function of the barrier and improving space utilization. At the same time, the push cylinders 50 on both sides drive the push steel balls 43 to push the support plate 44 to rotate on the fixed frame 45, adjusting the position of the photovoltaic panel 47 and ensuring the energy utilization rate of the photovoltaic panel 47. Meanwhile, the extended power supply 46 absorbs the energy converted by the photovoltaic panel 47 to power the indicator light strip 48 at night, improving the aesthetics of the barrier after its arrangement and enhancing the practicality of the product.
