Description

Technical Field

[0001] This utility model relates to the field of highway sound insulation, and in particular to a sound-absorbing panel for highway sound insulation. Background Technology

[0002] With the construction of highways and the increase in car ownership, traffic noise pollution has become increasingly serious, severely disrupting the normal lives of residents along highways. Installing sound-absorbing panels near residential areas along highways can improve the noise environment and reduce vehicle noise pollution. However, existing sound-absorbing panels typically have either straight or curved tops, resulting in limited functionality and making them unsuitable for the varying sound insulation requirements of different regions. Furthermore, in some coastal areas with heavy summer rainfall and frequent typhoons, the distance of rainwater on the panels affects their sound insulation performance. Moreover, strong typhoon winds can easily overturn the panels. Therefore, a new type of sound-absorbing panel for highway sound insulation is needed to address the problems of existing sound-absorbing panels' inability to adjust the top angle for noise reflection according to usage needs, poor drainage, and poor wind resistance. Utility Model Content

[0003] In response to the above situation and to overcome the shortcomings of the existing technology, this device provides a sound-absorbing panel for highway sound insulation. This device has good drainage effect and stability, and can also adjust the noise reflection angle of the top of the sound barrier sound-absorbing panel according to the usage requirements, thereby improving the practicality of the sound-absorbing panel.

[0004] The purpose of this utility model is to provide a sound-absorbing panel for highway sound insulation, including a sound-absorbing panel body, a base fixedly connected to the bottom end of the sound-absorbing panel body, a support mechanism provided at the rear end of the base to increase the stability of the sound-absorbing panel body after unfolding, an arc-shaped sound-absorbing panel hinged to the top end of the sound-absorbing panel, adjustment mechanisms for adjusting the angle of the arc-shaped sound-absorbing panel connected to both sides of the sound-absorbing panel body, a placement cavity for placing sound-absorbing cotton opened at the rear end of the sound-absorbing panel body, an installation plate fixedly connected to the outside of the placement cavity, a plurality of drainage holes opened at the bottom of the placement cavity, and a drainage pipe fixedly connected to the outlet end of the plurality of drainage holes.

[0005] Furthermore, the adjustment mechanism includes a fixed rod with a longitudinal groove at its top. A threaded rod is rotatably connected to the bottom of the longitudinal groove. A torsion block is coaxially fixed to the bottom of the threaded rod extending outside the longitudinal groove. A telescopic rod is vertically slidably connected inside the longitudinal groove. The bottom of the telescopic rod is threadedly connected to the threaded rod. A first rotating shaft and a second rotating shaft are fixedly connected to one side of the fixed rod and the telescopic rod, respectively. The fixed rod is rotatably connected to one side of the sound-absorbing plate body through the first rotating shaft, and the fixed rod is rotatably connected to one side of the arc-shaped sound-absorbing plate through the second rotating shaft.

[0006] Furthermore, the radial surface of the telescopic rod is symmetrically fixedly connected with limit blocks, and the inner wall of the longitudinal slide groove is provided with a limit groove that cooperates with the limit blocks, and the limit blocks and the limit grooves are slidably connected.

[0007] Furthermore, the support mechanism includes a storage slot, which is located at the bottom rear end of the base. A symmetrically arranged support rod is hinged to the top of the storage slot, and a positioning hole is provided at the front end of each support rod.

[0008] Furthermore, the sound-absorbing panel body and the front end of the arc-shaped sound-absorbing panel are fixedly connected with multiple protrusions.

[0009] Furthermore, a transparent plate is embedded at the front end of the sound-absorbing panel body.

[0010] Furthermore, multiple positioning pins for positioning the sound-absorbing cotton are fixedly connected inside the cavity.

[0011] The working principle and usage principle of this utility model are as follows: First, the device can adjust the tilt angle of the arc-shaped sound-absorbing panel at the top of the sound-absorbing panel body through the adjustment mechanism, so as to make it convenient to adjust the angle of sound reflection of the arc-shaped sound-absorbing panel according to the usage requirements. After the support mechanism is unfolded, it can increase the support effect of the sound-absorbing panel body and increase the wind resistance of the sound-absorbing panel body. Sound-absorbing cotton can be installed in the placement cavity opened at the rear end of the sound-absorbing panel body, which further increases the sound insulation effect of the sound-absorbing panel body. Multiple drainage outlets are opened at the bottom of the placement cavity, which can drain the water in the placement cavity through the drainage pipe during the rainy season or when the air is humid, thereby improving the drainage effect of the sound-absorbing panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Compared with the prior art, the present invention uses an arc-shaped sound-absorbing panel and an adjustment mechanism to adjust the angle of the sound-absorbing panel according to its position and needs, which makes it convenient for the sound-absorbing panel body to adjust the noise reflection angle according to the needs, thereby improving the sound insulation and sound absorption effect of the device.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0021] according to Figures 1 to 4 As shown, a sound-absorbing panel for highway sound insulation includes a sound-absorbing panel body 1, a base 2 fixedly connected to the bottom end of the sound-absorbing panel body 1, a support mechanism 6 provided at the rear end of the base 2 to increase the stability of the sound-absorbing panel body 1 after unfolding, an arc-shaped sound-absorbing panel 4 hinged to the top end of the sound-absorbing panel, and adjustment mechanisms 5 for adjusting the angle of the arc-shaped sound-absorbing panel 4 respectively connected to both sides of the sound-absorbing panel body 1, a placement cavity 8 for placing sound-absorbing cotton is opened at the rear end of the sound-absorbing panel body 1, an installation plate 7 is fixedly connected to the outside of the placement cavity 8, and multiple drainage holes 9 are opened at the bottom of the placement cavity 8, with drainage pipes 91 fixedly connected to the outlet ends of the multiple drainage holes 9.

[0022] In practical implementation, the sound-absorbing panel body 1 is installed at the required location via the base 2. The support mechanism 6 at the rear end of the base 2, when flipped open, increases the support for the sound-absorbing panel body 1, improving its wind resistance. Sound-absorbing cotton can be pre-installed in the placement cavity 8 at the rear end of the sound-absorbing panel body 1 to further process noise and improve its sound insulation and absorption effect. The arc-shaped sound-absorbing panel 4, rotatably connected to the top of the sound-absorbing panel body 1, can be adjusted forward or backward under the control of the adjustment mechanism 5, facilitating adjustments based on usage. The requirements are adjusted to adjust the sound absorption and reflection angle of the curved sound-absorbing panel 4. The drainage hole 9 in the placement cavity 8 can drain the water that accumulates in the placement cavity 8 in rainy or humid weather, avoiding the sound-absorbing cotton from getting wet and causing poor sound insulation and absorption. The water outlet is located at the bottom of the placement cavity 8 at the rear end of the sound-absorbing panel body 1. At the same time, the drainage pipe 91 is connected to the water outlet to facilitate water discharge and improve the drainage effect of the device. The mounting plate 7 can be connected to the sound-absorbing panel body 1 by bolts to seal the placement cavity 8.

[0023] Furthermore, the adjustment mechanism 5 includes a fixed rod 51, with a longitudinal groove 53 at the top end of the fixed rod 51. A threaded rod 54 is rotatably connected to the bottom end of the longitudinal groove 53. A torsion block 55 is coaxially fixedly connected to the bottom end of the threaded rod 54 extending to the outside of the longitudinal groove 53. A telescopic rod 56 is vertically slidably connected inside the longitudinal groove 53. The bottom end of the telescopic rod 56 is threadedly connected to the threaded rod 54. A first rotating shaft 52 and a second rotating shaft 67 are fixedly connected to one side of the fixed rod 51 and the telescopic rod 56, respectively. The fixed rod 51 is rotatably connected to one side of the sound-absorbing plate body 1 through the first rotating shaft 52, and the fixed rod 51 is rotatably connected to one side of the arc-shaped sound-absorbing plate 4 through the second rotating shaft 67.

[0024] In practical implementation, the fixed rod 51 and the telescopic rod 56 are rotatably connected to the sound-absorbing plate body 1 and the arc-shaped sound-absorbing plate 4 through the first rotating shaft 52 and the second rotating shaft 67, respectively. When the torsion block 55 is rotated, the threaded connection between the threaded hole at the bottom of the telescopic rod 56 and the threaded rod 54 causes the torsion block 55 to rotate axially, thereby causing the telescopic rod 56 to slide up and down in the longitudinal groove 53 of the fixed rod 51. When the telescopic rod 56 slides upward, the first rotating shaft 52 and the second rotating shaft 67 are used to flip the arc-shaped sound-absorbing plate 4 upward, thereby increasing the angle between the arc-shaped sound-absorbing plate 4 and the sound-absorbing plate body 1. Conversely, when the telescopic rod 56 slides into the longitudinal groove 53, the first rotating shaft 52 and the second rotating shaft 67 are used to flip the arc-shaped sound-absorbing plate 4 downward, thereby decreasing the angle between the arc-shaped sound-absorbing plate 4 and the sound-absorbing plate body 1, thereby adjusting the noise reflection angle.

[0025] Furthermore, the radial surface of the telescopic rod 56 is symmetrically fixedly connected with a limiting block 68, and the inner wall of the longitudinal slide groove 53 is provided with a limiting groove that cooperates with the limiting block 68, and the limiting block 68 is slidably connected with the limiting groove.

[0026] In practical implementation, the telescopic rod 56 can slide vertically within the longitudinal slide groove 53 through the cooperation of the limiting block 68 and the limiting groove, which facilitates the adjustment of the length of the telescopic rod 56.

[0027] Furthermore, the support mechanism 6 includes a storage groove 61, which is located at the bottom rear end of the base 2. A symmetrically arranged support rod 62 is hinged to the top of the storage groove 61, and a positioning hole 63 is provided at the front end of each support rod 62.

[0028] In practical implementation, after the support rod 62 is unfolded, the positioning pin 81 is embedded in the positioning hole 63 to fix the support rod 62 to the ground, so that the two support rods 62 in the storage groove 61 can increase the wind resistance of the sound-absorbing panel body 1. When it is not necessary to improve the wind resistance of the sound-absorbing panel body 1, storing the two support rods 62 in the storage groove 61 can facilitate the use of the sound-absorbing panel body 1 and reduce the floor space occupied.

[0029] Furthermore, multiple protrusions 11 are fixedly connected to the front ends of the sound-absorbing panel body 1 and the arc-shaped sound-absorbing panel 4.

[0030] In practical implementation, the multiple protrusions 11 provided at the front end of the sound-absorbing panel body 1 and the arc-shaped sound-absorbing panel 4 can increase the noise reflection effect and further improve the sound insulation and sound absorption effect of the device.

[0031] Furthermore, a transparent plate 3 is embedded at the front end of the sound-absorbing panel body 1.

[0032] In practical implementation, the transparent plate 3 can increase the light transmission effect of the device and improve its aesthetics.

[0033] Furthermore, multiple positioning pins 81 for positioning the sound-absorbing cotton are fixedly connected inside the placement cavity 8.

[0034] In practice, the sound-absorbing cotton inside the placement cavity 8 is fixed by the positioning pin 81, which improves the installation efficiency and fixing effect of the sound-absorbing cotton and prevents the sound-absorbing cotton from deforming after being soaked by rainwater, thus affecting the sound absorption effect of the sound-absorbing cotton.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
