[0003] Patent CN 111395218 A discloses a metal sound barrier unit panel, including a shell, a panel opening, and a sound absorbing material. The shell is a rectangular parallelepiped structure, and the shell includes a front and rear panel and a back panel, an upper connecting plate, and a lower connecting plate. The panel opening is located on the panel, and the upper edge of the panel is folded toward the back panel to form an upper flange, and the upper edge of the back panel is folded toward the panel to form an upper flange.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The purpose of the utility model is to provide a waterproof self-closing metal sound barrier with a detection function to solve the problems existing in the prior art. It can detect the sound-absorbing components, facilitate the inspection of the effectiveness of the sound barrier, and carry out timely maintenance. It also has a certain waterproof ability and can increase the service life of the sound-absorbing components.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1-Figure 12As shown, this embodiment provides a waterproof self-closing metal sound barrier with detection function, including a sound absorbing component 1, a protective shell 2, a lower main beam 3, an upper main beam 4 and an elastic damping buffer 5;

[0038] The sound absorbing component 1 is vertically arranged in the protective shell 2, and the sound absorbing component 1 includes a panel 6 and a back panel 7. The panel 6 and the back panel 7 are connected to each other and form a filling space therebetween. The filling space is filled with a sound absorbing material 8. The sound absorbing material 8 is embedded with a sound absorbing material detection component 9 for detecting the sound absorption effect of the sound barrier. The panel 6 is provided with a plurality of sound absorbing holes 10.

[0039] The lower main beam 3 is arranged between the sound absorbing component 1 and the protective shell 2, and is used to support the sound absorbing component 1. An elastic damping buffer 5 is respectively arranged between the lower ends of the panel 6 and the back plate 7 and the lower main beam 3. The upper end of the protective shell 2 is provided with two baffles 11 extending downward, and a first plug-in slot 12 is formed between the two baffles 11. The upper end of the sound absorbing component 1 is plugged into the first plug-in slot 12.

[0040] The upper main beam 4 is arranged at the upper end of the protective shell 2. The upper main beam 4 is an inverted I-shaped structure. The upper end of the protective shell 2 is plugged into the lower notch of the inverted I-shaped structure. The upper notch of the inverted I-shaped structure is used for plugging the lower end of the protective shell 2 of the sound barrier above it.

[0041] The side panel of the protective shell 2 opposite to the panel 6 is a sound-absorbing panel 13, on which a plurality of through holes 14 are provided, and a plurality of snap-fit ​​components 16 are riveted to the inner side of the sound-absorbing panel 13 through anchor nuts 15, and the anchor holes in the middle of each anchor nut 15 are connected to the inner and outer spaces of the protective shell 2, and a flap shaft 17 is rotatably connected between each snap-fit ​​component 16 and the protective shell 2, and a flap assembly 18 is fixedly connected to each flap shaft 17 for covering part of the through holes 14, and when subjected to wind pressure load, the flap assembly 18 can be flipped inward through the flap shaft 17 to open the through hole 14 covered by it.

[0042] When subjected to wind pressure load, the flap assembly 18 can be turned inwards through the flap rotating shaft 17 to open the through hole 14 blocked by it, and the wind pressure energy and noise can enter the protective shell 2 through the through holes 14 and the anchor hole in the middle of the anchor nut 15, and enter the sound absorbing assembly 1 through the sound absorbing hole 10 on the panel 6 of the sound absorbing assembly 1, and the noise is absorbed by the sound absorbing material 8. When not subjected to wind pressure load, the flap assembly 18 is freely turned over and falls under the action of gravity to block the through hole 14 corresponding to it. In bad weather such as rain and snow, since the flap assembly 18 can block part of the through holes 14, The water vapor entering the protective shell 2 is reduced, and the space between the protective shell 2 and the sound absorbing component 1 can buffer the water vapor entering, further reducing the amount of water vapor entering the sound absorbing component 1, thereby increasing the service life of the sound absorbing component 1. At the same time, the elastic damping buffer 5 can buffer the wind force on the sound absorbing component 1, reduce the force on the sound absorbing component 1, thereby increasing its service life; by embedding the sound absorbing material detection component 9 in the sound absorbing material 8, the sound absorption efficiency of the sound absorbing material 8 can be timely detected, which is convenient for checking the effectiveness of the sound barrier and timely maintenance. The anchor hole in the anchor nut 15 can also connect the inner and outer spaces of the protective shell 2 by riveting the snap-fit ​​component 16, ensuring the opening rate of the sound absorbing panel 13, which is conducive to the entry of noise to be absorbed by the sound absorbing component 1.

[0043] In this embodiment, an end plate 19 is provided at each end of the protective shell 2 in the length direction, and a reserved hole 20 is provided on the end plate 19 for inserting a steel wire rope 21, which is used to be fixed on the sound barrier steel. Slots 22 are provided at both ends of the end plate 19, which are plugged and connected with the two side panels of the protective shell 2 and riveted by rivets. Two vertical baffles 23 extending inward are provided on the end plate 19, and a second plug-in groove 24 is formed between the two vertical baffles 23. The two ends of the sound absorbing component 1 in the length direction are respectively plugged into the two second plug-in grooves 24. The two vertical baffles 23 of the end plate 19 are used to limit the ends of the sound absorbing component 1 in the length direction to ensure the stability of the sound absorbing component 1.

[0044] In this embodiment, the lower main beam 3 is a U-shaped structure, and the bottom plate of the U-shaped structure of the lower main beam 3 is supported on the bottom plate of the protective shell 2. The two side plates of the U-shaped structure of the lower main beam 3 are respectively abutted against the two side plates of the protective shell 2. Two connecting plates 25 extending upward are fixedly provided on the bottom plate of the U-shaped structure of the lower main beam 3. A U-shaped groove 26 is formed between the side plates of the U-shaped structure of the lower main beam 3 and the connecting plates 25 on the same side thereof. The upper ends of the two connecting plates 25 are bent inward 180° to form a snap-fit ​​structure. The elastic damping buffer 5 includes a supporting bottom plate 27 and a serpentine damping plate 28 that are interconnected. The serpentine damping plate 28 is snap-fitted with the snap-fit ​​structure. The lower end of the sound absorbing assembly 1 is supported on the two supporting bottom plates 27 on both sides and is located between the two serpentine damping plates 28 on both sides. When the sound absorbing component 1 is subjected to force, the kinetic energy is converted into elastic potential energy through the buffering of the buckle structure and the elastic damping buffer 5, and the kinetic energy is converted into thermal potential energy through high and low frequency vibrations and then consumed, thereby reducing the force on the sound absorbing component 1, thereby increasing its service life. The U-shaped groove 26 can be used as a water guide groove, and rain, snow or water vapor entering the protective shell 2 through the through hole or anchor hole on the protective shell 2 can be collected in the U-shaped groove 26, and the water flow is guided out from the gap on one side through the U-shaped groove 26.

[0045] In this embodiment, the first plug-in slot 12 is connected to the outside world upward and to the inside of the protective shell 2 downward. Two plug-in plates 29 extending downward are fixedly provided at the bottom of the inverted I-shaped intermediate connecting plate. The two plug-in plates 29 are inserted into the first plug-in slot 12 and respectively abut against the sides of the two baffles 11. A third plug-in slot 30 is formed between the two plug-in plates 29. The upper end of the sound absorbing component 1 is inserted into the third plug-in slot 30 through the first plug-in slot 12. By inserting the two plug-in plates 29 into the first plug-in slot 12 and respectively abutting against the sides of the two baffles 11, the stability of the structure can be improved, and the wind pressure resistance of the sound barrier can be improved. During installation, after the sound absorbing component 1 is installed in the protective shell 2, the upper main beam 4 is installed at the upper end of the protective shell 2, so that the two plug-in plates 29 are inserted into the first plug-in slot 12 and respectively abut against the sides of the two baffles 11, and the upper end of the sound absorbing component 1 extends into the third plug-in slot 30, which is convenient for installation.

[0046] In this embodiment, a U-shaped rubber strip 31 is further provided in the upper notch of the inverted I-shaped structure, which is used to seal and connect with the lower end of the protective shell 2 of the sound barrier above it, and the inner surface of the U-shaped rubber strip 31 has a serrated structure. When multiple sound barriers are arranged in sequence in the height direction, the upper protective shell 2 can be sealed and connected with the upper main beam 4 through the U-shaped rubber strip 31 to prevent noise from passing between two adjacent protective shells 2, thereby improving the overall acoustic performance of the sound barrier. The U-shaped rubber strip 31 is EPDM rubber, and the serrated structure of the EPDM rubber can further isolate part of the sound and improve the acoustic performance.

[0047] In this embodiment, a filling hole 32 extending in the height direction is provided in the sound absorbing material 8, and the sound absorbing material detection component 9 is filled in the filling hole 32, and polyurethane foam 33 is filled between the upper and lower ends of the filling space and the sound absorbing material 8. The sound absorbing material 8 includes rock wool and glass wool, and the sound absorbing material detection component 9 includes colored foam and gel toner. After the sound absorbing material 8 collapses, the colored foam or gel toner will float out, and the maintenance personnel can check whether the sound barrier has the effect of continued use through inspection.

[0048] In this embodiment, the protective housing 2 is an aluminum alloy housing, the elastic damping buffer 5 is an aluminum alloy profile, the buckle assembly 16 is an aluminum alloy material, and the end plate 19 is an aluminum alloy profile. Aluminum alloy materials have the advantages of light weight and corrosion resistance.

[0049] The panels in the sound barrier adopt integrated bending technology, which can effectively avoid the risk of fatigue fracture at the joints of the sound barrier during use.

[0050] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
