Description

Technical Field

[0001] This utility model relates to the field of highway technology; more specifically, it relates to a sound barrier for highway sound insulation and noise reduction. Background Technology

[0002] Highways are the core arteries of modern transportation networks. They typically refer to two-way, multi-lane trunk roads with high design standards, full interchanges, and full enclosures. Their main characteristics are central median, strict access control, and complete elimination of at-grade intersections and interference from pedestrians and non-motorized vehicles.

[0003] Highway noise barriers are sound insulation structures specifically designed to reduce the impact of traffic noise on residents along the route. Their core mechanism lies in effectively blocking, isolating, or absorbing the sound wave energy generated by vehicles through specially designed barriers. These facilities significantly reduce noise pollution, improve the living environment around highways, and are an important measure in highway environmental protection infrastructure.

[0004] Currently, existing sound barriers for highway noise reduction face several challenges. Highways typically feature numerous curves, and the existing sound barrier panels are usually straight, making installation inflexible and time-consuming, potentially disrupting traffic and reducing the equipment's practicality. Furthermore, the installation height varies depending on the location and distance from residential areas, and current equipment often lacks the ability to quickly adjust this height, potentially impacting the noise reduction effect and reducing usability. Therefore, a new type of sound barrier for highway noise reduction is urgently needed to address these issues. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sound barrier for highway sound insulation and noise reduction, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a sound barrier for noise reduction on highways, comprising:

[0007] An adjustment structure is provided at its upper end with a splicing structure; the adjustment structure includes a first hinge seat, a second hinge seat, and a ground nail, and the first hinge seat and the second hinge seat are hinged to each other; the splicing structure includes a first hinge connecting block, and the first hinge connecting block is engaged inside the upper end of the first hinge seat.

[0008] Preferably, the ground nails are provided in two sets, and the two sets of ground nails are respectively fixedly connected to the outer surface of the lower end of the first hinge seat and the second hinge seat. This design allows the angle of the equipment to be adjusted through the first hinge seat and the second hinge seat.

[0009] Preferably, the ground nail is cone-shaped, wider at the top and narrower at the bottom. This design facilitates the driving of the ground nail into the ground.

[0010] Preferably, the second hinge connecting block is engaged inside the upper end of the second hinge seat. Multiple sets of insertion slots are provided, and these slots are respectively opened inside the upper outer surfaces of the first hinge seat, the second hinge seat, the first hinge connecting block, and the second hinge connecting block. Multiple sets of insertion blocks are provided, and these blocks are respectively opened on the lower outer surfaces of the first and second hinge connecting blocks. A first bolt is threaded into the inner surface of one side of the insertion slot. A sound barrier plate is engaged inside the outer surface of the outermost end of the first and second hinge connecting blocks. The engaging plate is fixedly connected to the upper outer surface of the sound barrier plate. The engaging slot is opened inside the lower outer surface of the sound barrier plate. Multiple sets of second bolts are provided, and all sets of second bolts are threaded into the inner surface of one side of the engaging slot. This design achieves sound insulation and noise reduction by installing the sound barrier plate.

[0011] Preferably, the internal dimensions of the insertion slot are adapted to the external dimensions of the insertion block, and a threaded groove is provided on the inner surface of one side of the outer surface of the insertion block. The position of the threaded groove corresponds to the position of the first bolt, and the inner wall surface of the threaded groove is adapted to the outer surface of the first bolt. This design allows multiple sets of first hinged connecting blocks and second hinged connecting blocks to be spliced ​​vertically by inserting the insertion block into the insertion slot.

[0012] Preferably, the outer surfaces of the first and second hinged connecting blocks are provided with T-shaped grooves, the outer surfaces of both ends of the sound barrier panel are provided with T-shaped blocks, and the external dimensions of the T-shaped blocks are adapted to the internal dimensions of the T-shaped grooves. The external dimensions of the locking plate are adapted to the internal dimensions of the locking grooves. The outer surface of the locking plate is provided with a connecting groove, and the position of the connecting groove corresponds to the position of the second bolt. The inner wall surface of the connecting groove is adapted to the outer surface of the second bolt. This design allows for the splicing of two sets of sound barrier panels by engaging the locking grooves at the lower end of one set of sound barrier panels with the outer surface of the locking plate at the upper end of another set of sound barrier panels.

[0013] The technical effects and advantages of this utility model are as follows: By hinged and rotating the first hinge seat and the second hinge seat, the angle between the first hinge seat and the second hinge seat can be adjusted according to the actual installation angle. Then, by nailing the first hinge seat and the second hinge seat into the ground with ground nails, the angle between the first hinge seat and the second hinge seat can be positioned. Thus, the angle of the sound barrier plate installed on it can be controlled by the first hinge seat and the second hinge seat, avoiding the inconvenience of installing the sound barrier plate on the curve of the highway, and improving the practicality of the equipment to a certain extent.

[0014] By inserting the lower end insertion blocks of the first and second hinge connecting blocks into the upper insertion slots of the first and second hinge seats respectively, and by rotating the first bolt into the threaded groove, the positions of the first and second hinge connecting blocks can be determined. Similarly, by inserting the lower end insertion blocks of one set of first and second hinge connecting blocks into the upper insertion slots of another set of first and second hinge connecting blocks, another set of first and second hinge connecting blocks can be spliced ​​onto the upper end of one set of first and second hinge connecting blocks. The second hinged connecting block allows for the installation of sound barrier panels by engaging the T-shaped block into the T-shaped groove. By engaging the lower end of one set of sound barrier panels with the outer surface of the upper end of another set of sound barrier panels, and simultaneously rotating the second bolt into the connecting groove, the two sets of sound barrier panels can be joined. Similarly, the number of sound barrier panels can be adjusted according to actual needs, allowing for relatively quick adjustment of the sound barrier height. This improves the ease of use of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The sound barrier for highway noise reduction involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1, as Figure 1 and Figure 2 As shown in the figure, this embodiment proposes a sound barrier for highway noise reduction, comprising:

[0022] Adjustment structure 1, with splicing structure 2 at the upper end of adjustment structure 1; adjustment structure 1 includes a first hinge seat 11, a second hinge seat 12 and ground nail 13, and the first hinge seat 11 and the second hinge seat 12 are hinged to each other, and there are two sets of ground nails 13, and the two sets of ground nails 13 are respectively fixedly connected to the outer surface of the lower end of the first hinge seat 11 and the second hinge seat 12, and the ground nail 13 is tapered with a larger upper part and a smaller lower part;

[0023] In this embodiment, the angle between the sound barrier panels 26 can be adjusted by adjusting the hinge angle between the first hinge seat 11 and the second hinge seat 12. At the same time, the angle between the first hinge seat 11 and the second hinge seat 12 can be positioned by driving the ground nail 13 into the ground. The conical design of the ground nail 13 can reduce the resistance when the ground nail 13 is driven into the ground.

[0024] Example 2, as Figure 3 and Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0025] The splicing structure 2 includes a first hinge connecting block 21, which engages with the interior of the upper end of the first hinge seat 11; a second hinge connecting block 22, which engages with the interior of the upper end of the second hinge seat 12; multiple sets of insertion slots 23 are provided, and these slots 23 are respectively opened inside the upper outer surfaces of the first hinge seat 11, the second hinge seat 12, the first hinge connecting block 21, and the second hinge connecting block 22; multiple sets of insertion blocks 24 are provided, and these blocks 24 are respectively opened on the lower outer surfaces of the first hinge connecting block 21 and the second hinge connecting block 22; a first bolt 25 is threaded into the interior of one side of the outer surface of the insertion slot 23; the internal dimensions of the insertion slot 23 are adapted to the external dimensions of the insertion block 24; and a threaded bolt is opened into the interior of one side of the outer surface of the insertion block 24. The groove is positioned to correspond to the position of the first bolt 25, and the inner surface of the groove is adapted to the outer surface of the first bolt 25. This design allows the insertion block 24 at the lower end of a set of first hinged connecting blocks 21 and second hinged connecting blocks 22 to be inserted into the insertion groove 23 at the upper end of another set of first hinged connecting blocks 21 and second hinged connecting blocks 22. The insertion block 24 is more stable when inserted into the insertion groove 23. Thus, the two sets of first hinged connecting blocks 21 and second hinged connecting blocks 22 can be spliced ​​vertically. At the same time, the first bolt 25 is rotated into the groove, and the first bolt 25 is more stable inside the groove. Thus, the splicing between the two sets of first hinged connecting blocks 21 and second hinged connecting blocks 22 is more stable.

[0026] A sound barrier plate 26 is internally engaged with the outermost surfaces of the first hinge connecting block 21 and the second hinge connecting block 22. A engaging plate 27 is fixedly connected to the upper outer surface of the sound barrier plate 26. An engaging groove 28 is formed inside the lower outer surface of the sound barrier plate 26. Multiple sets of second bolts 29 are provided, and all sets of second bolts 29 are threaded into the inner surface of one side of the engaging groove 28. T-slots are formed inside the outermost surfaces of the first hinge connecting block 21 and the second hinge connecting block 22. T-shaped blocks are formed on the outer surfaces of both ends of the sound barrier plate 26, and the external dimensions of the T-shaped blocks match the internal dimensions of the T-slots. The external dimensions of the engaging plate 27 match the internal dimensions of the engaging groove 28. A connecting groove is formed on the outer surface of the engaging plate 27. The position of the groove corresponds to the position of the second bolt 29, and the inner wall surface of the groove is adapted to the outer surface of the second bolt 29. This design allows the sound barrier panel 26 to be installed inside the first hinged connecting block 21 and the second hinged connecting block 22 by snapping the T-shaped block into the T-shaped groove, and the installation is more stable. By snapping the locking groove 28 at the lower end of one set of sound barrier panels 26 into the outer surface of the locking plate 27 at the upper end of another set of sound barrier panels 26, the locking groove 28 is more stable when it is on the outer surface of the locking plate 27. At the same time, the second bolt 29 is rotated into the groove, and the second bolt 29 is more stable when it is in the groove. Thus, the two sets of sound barrier panels 26 can be spliced ​​together, and the splicing is more stable.

[0027] The sound barrier panel 26 is a common sound barrier device used for noise reduction on highways, and it is a product that can be purchased directly on the market. Its principle, connection method and control method are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0028] The first hinge seat 11, the second hinge seat 12, the first hinge connecting block 21 and the second hinge connecting block 22 in this application, as well as all movable parts, need to be cleaned and maintained regularly, including but not limited to dust removal and lubrication.

[0029] Working principle: When using the equipment, firstly, adjust the first hinge seat 11 and the second hinge seat 12 to a suitable angle according to the required angle of the equipment's installation position. Then, drive the ground nail 13 into the ground to position the angle of the first hinge seat 11 and the second hinge seat 12. Next, insert a set of first hinge connecting blocks 21 and second hinge connecting blocks 22 into the upper end of the first hinge seat 11 and the second hinge connecting blocks 22 respectively, and position the first hinge connecting blocks 21 and the second hinge connecting blocks 22 by rotating the first bolt 25. Then, according to the actual required installation height, insert the insertion blocks 24 at the lower end of another set of first hinge connecting blocks 21 and second hinge connecting blocks 22 into the insertion slots 23 at the upper end of another set of first hinge connecting blocks 21 and second hinge connecting blocks 22 respectively, and position the new set by rotating the first bolt 25. Position the first hinge block 21 and the second hinge block 22. Similarly, based on the length of the sound barrier plate 26, install another set of first hinge seats 11 and second hinge seats 12 in appropriate positions and install the corresponding number of first hinge blocks 21 and second hinge blocks 22. Then, engage the T-shaped blocks at both ends of the sound barrier plate 26 into the T-shaped grooves to install one set of sound barrier plates 26. At the same time, engage the engagement groove 28 at the lower end of the other set of sound barrier plates 26 into the outer surface of the engagement plate 27 at the upper end of the first set of sound barrier plates 26. Position the two sets of sound barrier plates 26 by rotating the second bolt 29. Similarly, the number of sets and the height of the sound barrier plates 26 can be adjusted according to actual needs. This completes the installation of the sound barrier for highway noise reduction. The above is the entire working principle of this utility model.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
