Description

Technical Field

[0001] The present invention relates to the technical field of urban traffic noise elimination and reduction, and specifically to a multifunctional fully enclosed sound barrier system that can intelligently control the exhaust area. Background Art

[0002] With the acceleration of urbanization, public transportation facilities such as urban expressways and rail transit have rapidly developed. While these facilities promote economic development and improve people's living standards, they also generate increasingly prominent traffic noise pollution. Traffic noise has become a major source of pollution for sensitive residential areas. Addressing environmental noise pollution is an inevitable requirement for building an ecologically civilized society, and constructing sound barriers is an important technical means of controlling traffic noise pollution.

[0003] A sound barrier is an acoustic baffle standing between the noise source and the sound receiving point, separating the sound source from the protected target, causing significant additional attenuation of sound wave propagation, thereby reducing the impact of noise in the area where the protected target is located.

[0004] Fully enclosed sound barriers, with their enclosed structure, block noise transmission, achieving far greater noise reduction than conventional upright sound barriers. Widely used in noise-sensitive areas such as highways, railways, and industrial facilities, they significantly improve the surrounding acoustic environment while also balancing aesthetics and space utilization. However, due to fire protection requirements, fully enclosed sound barriers typically require sufficient ventilation area at the top (2%-5% of the total area). This exhaust area creates an acoustic leakage channel, reducing noise reduction by 3-5dB(A), thereby lowering the noise reduction efficiency of fully enclosed sound barriers.

[0005] Therefore, a multifunctional fully enclosed sound barrier system with intelligent control of exhaust area is proposed to solve the above problems. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a multifunctional fully enclosed sound barrier system with intelligent control of the exhaust area. The fully enclosed sound barrier can switch between open exhaust and closed sound insulation states according to needs. It can exhaust a large area in times of fire and other times, and maintain the complete noise reduction function of the fully enclosed sound barrier in daily operation, solving the problem that it is difficult to achieve both exhaust and sound insulation with a fully enclosed sound barrier.

[0007] To achieve the above object, the present invention provides the following technical solutions: A multifunctional fully enclosed sound barrier system with intelligent ventilation area control includes steel columns, each provided with a sound-absorbing barrier, fixedly connected to a main steel beam, to which an umbrella-shaped steel frame is fixedly connected; a translationally openable sound barrier device is provided on the main steel beam; the translationally openable sound barrier device includes a guide rail, provided on the main steel beam, with a roller slidably connected to the guide rail, the top of the roller fixedly connected to an aluminum alloy frame, and a polycarbonate plate fixedly connected to the aluminum alloy frame; a control device is provided on the main steel beam, and an internal temperature sensor and a smoke sensor are integrated into the control device; The sealing compensation system includes: the mortise and tenon joints are used between the horizontal sliding opening sound barrier devices; Use rubber strips between the bottom of the sliding openable sound barrier device and the main steel beam; The longitudinal overlapping area of the sliding and opening sound barrier device is provided with an acoustic damping coating.

[0008] Preferably, the bottom of the main steel beam is located below the translational opening sound barrier device and is fixedly connected to a matching component; The mating component includes a mouth-shaped frame, which is fixedly connected to the bottom of the main steel beam. A guide fan is provided on the mouth-shaped frame. A guide pipe is connected to the bottom area of the mouth-shaped frame. A first valve is provided in the area inside the mouth-shaped frame. The bottom of the mouth-shaped frame is fixedly connected to the upper end of the upper shielding bag.

[0009] Preferably, the mouth-shaped frame is hollowed out to form an embedding groove, the embedding groove is a mouth-shaped structure, and the embedding groove is rotatably connected with driving wheels around it. The center of a group of driving wheels is fixedly connected to the output shaft of the driving motor, and multiple groups of driving wheels are connected through belt transmission. The four corners of the bottom of the mouth-shaped frame are rotatably connected with guide frames.

[0010] Preferably, the center of the guide frame is fixedly connected to the driving wheel, and a pulling wire is wound on the side of the winding wheel. One end of the pulling wire slides through the guide frame and is fixedly connected to one end of the counterweight frame, and the surface of the counterweight frame is fixedly connected to the shielding telescopic bag.

[0011] Preferably, the upper end of the shielding telescopic bag is communicated with the bottom of the upper shielding bag, a contact rope is connected to the shielding telescopic bag, and the contact rope is stacked in parallel with the shielding telescopic bag in multiple layers or cross-stacked with each other.

[0012] Preferably, the side wall of the mouth-shaped frame is fixedly connected with a connecting plate, and the side wall of the connecting plate is bolted to a servo motor.

[0013] Preferably, the output shaft of the servo motor is fixedly connected to the center of the incomplete gear, and the incomplete gear is rotatably connected to the connecting plate.

[0014] Preferably, the connecting plate is rotatably connected to the gear via a torsion spring, and the center of the gear is fixedly connected to the side wall of the spray pipe.

[0015] Preferably, a plurality of groups of illumination lamps are equidistantly provided on both ends of the surface of the spray pipe, the upper end of the spray pipe is connected to a bellows, and the upper end of the bellows is connected to the guide pipe through a first valve.

[0016] Compared with the existing technology, the present invention provides a multifunctional fully enclosed sound barrier system with intelligent control of exhaust area, which has the following beneficial effects: 1. The present invention can switch between open exhaust and closed sound insulation states according to needs through a fully enclosed sound barrier. It can exhaust air on a large scale in times of fire and other situations, and maintain the complete noise reduction function of the fully enclosed sound barrier in daily operation, solving the problem that it is difficult to achieve both exhaust and sound insulation with a fully enclosed sound barrier.

[0017] 2. In the event of a fire, the present invention quickly deploys the shielding telescopic bag through the driving system, so that it is located above the fire source or wraps the fire source. This is equivalent to quickly building a temporary "smoke hood" or "chimney" above the fire area. At the same time, the guide fan is started to forcefully discharge the smoke gathered in the shielding telescopic bag through the sound barrier opening opened above the main steel beam, effectively controlling the direction of smoke spread, preventing smoke from spreading disorderly in the road space, improving visibility, and creating favorable conditions for personnel evacuation and fire fighting.

[0018] 3. In this invention, as smoke rises, it collides with the numerous contact ropes suspended within the shielding and telescopic bag. Solid particles in the smoke (such as smoke dust and incomplete combustion) adhere to the contact ropes. Liquid can then be poured directly from below the device to the precise area of the fire below, achieving targeted fire extinguishing. A servo motor drives the spray pipe to swing back and forth, spraying the liquid in the form of a fan-shaped water curtain, expanding the coverage area of a single point, more effectively suppressing the fire and cooling the surrounding area. As the spray pipe swings, the light projects a fan-shaped, dynamically oscillating light band on the ground or the sidewalls of the steel columns. This dynamic, directional light signal can more quickly and intuitively warn passing vehicles to avoid the fire lane (the left or right end area) in a noisy and chaotic fire scene than static signs or sound alarms, greatly improving driving safety. The servo motor drives the spray pipe to rotate back and forth to beat the surface of the telescopic bag. The vibration generated by the beating loosens and falls off the particles adhering to the surface of the contact rope, and drops to the bottom area of the counterweight frame below, which greatly facilitates subsequent manual or automatic cleaning work.

[0019] 4. The present invention pulls the counterweight frame and the shielding telescopic bag back to their original position by pulling the steel wire. The shielding telescopic bag is refolded and compressed. Multiple groups of contact ropes form a sound absorption area. The tightly overlapping contact ropes form a dense area with porous sound absorption characteristics under the sliding and opening sound barrier device. This area effectively absorbs road noise, allowing the sound barrier to restore its core noise reduction function. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Further, such as Figures 1-9 As shown, the bottom of the main steel beam 2 is located below the translational opening sound barrier device 4 and is fixedly connected with a matching component 9; The matching component 9 includes a mouth-shaped frame 91, which is fixedly connected to the bottom of the main steel beam 2. The mouth-shaped frame 91 is provided with a guide fan 92. The bottom area of the mouth-shaped frame 91 is connected to a guide pipe 93. The guide pipe 93 is located in the inner area of the mouth-shaped frame 91 and is provided with a first valve 94. The bottom of the mouth-shaped frame 91 is fixedly connected to the upper end of the upper shielding bag 95. At the same time, if Figures 1-9 As shown, the mouth-shaped frame 91 is hollowed out to form an embedding groove 911, the embedding groove 911 is a mouth-shaped structure, and the embedding groove 911 is rotatably connected to the driving wheel 913 around it. The center of a group of driving wheels 913 is fixedly connected to the output shaft of the driving motor 912, and multiple groups of driving wheels 913 are connected through belt transmission. The four corners of the bottom of the mouth-shaped frame 91 are rotatably connected to the guide frame 915, and the center of the guide frame 915 is fixedly connected to the driving wheel 913. The side of the winding wheel 914 is wound Pull the steel wire 916, and slide one end of the steel wire 916 through the guide frame 915 and fixedly connected to one end of the counterweight frame 918. The surface of the counterweight frame 918 is fixedly connected to the shielding telescopic bag 917. The upper end of the shielding telescopic bag 917 is connected to the bottom of the upper shielding bag 95. A contact rope 919 is connected to the shielding telescopic bag 917, and the contact rope 919 and the shielding telescopic bag 917 are stacked in parallel in multiple layers or cross-stacked with each other; the contact rope 919 is specifically a ceramic fiber strip.

[0028] Further, if Figures 1-9 As shown, the side wall of the mouth-shaped frame 91 is fixedly connected to a connecting plate 931, and the side wall of the connecting plate 931 is bolted to a servo motor 932. The output shaft of the servo motor 932 is fixedly connected to the center of the incomplete gear 933. The incomplete gear 933 is rotatably connected to the connecting plate 931. The connecting plate 931 is rotatably connected to the gear 934 through a torsion spring. The center of the gear 934 is fixedly connected to the side wall of the spray pipe 935.

The upper end of the bellows 936 is connected to the guide pipe 93 through the first valve 94.

[0029] like Figures 1-9 As shown, the principle of the multifunctional fully enclosed sound barrier system with intelligent control of exhaust area provided in this embodiment is as follows: When a fire occurs, the translational opening sound barrier device 4 is opened to expand the opening above the main steel beam 2. The driving motor 912 can be controlled to drive a set of driving wheels 913 to rotate, and then the driving wheels 913 and the belts simultaneously drive multiple sets of winding wheels 914 to rotate, and the winding wheels 914 release the winding of the pulling wire 916. The pulling wire 916 drives the counterweight frame 918 to move downward, and the counterweight frame 918 drives the shielding telescopic bag 917 to move downward and expand to a suitable height in the steel column 1. Then, the guide fan 92 is turned on to drive the air in the shielding telescopic bag 917 to be transmitted upward and discharged outward through the opening above the main steel beam; The shielding telescopic bag 917 and the counterweight frame 918 can be located at the upper end of the fire source or wrap the fire source inside, and then the smoke enters the shielding telescopic bag 917, and then through the contact with the contact rope 919, the particles on the smoke adhere to the upper surface of the contact rope 919, and then the smoke rises and is discharged outward through the opening. After the fire is extinguished, the translational openable sound barrier device 4 is closed, and the servo motor 932 is turned on to drive the incomplete gear 933 to rotate, and the incomplete gear 933 engages to drive the gear 934 to rotate, and the gear 934 drives the spray pipe 935 to rotate back and forth, and the spray pipe 935 can also slap the surface of the shielding telescopic bag 917, the contact rope 919 in the shielding telescopic bag 917, and the particles adhered to the surface fall to the bottom of the counterweight frame 918, so that the particles can be easily cleaned; In case of fire, the two groups of first valves 94 can be opened. One group of first valves 94 can deliver liquid to the mouth frame 91 and the shielding telescopic bag 917, and can accurately deliver water to the fire area below. The swinging spray pipe 935 can spray the liquid outward in a fan shape to the area below. By turning on the irradiation lamp 937 on the side wall of the spray pipe 935, the ray emitted by the irradiation lamp 937 swings in a fan shape and irradiates the side wall of the steel column 1. When the left lane is on fire, the left illumination light 937 is turned on; when the right lane is on fire, the right illumination light 937 is turned on, thereby quickly and clearly reminding the outside vehicles that the left or right end area of the road is on fire; After the fire is extinguished, the sliding and opening sound barrier device 4 is closed, and the driving motor 912 is controlled to indirectly pull the counterweight frame 918 upward by pulling the steel wire 916 to reset it to contact with the steel column 1, and the counterweight frame 918 drives the shielding telescopic bag 917 to fold and make the contact ropes 919 in the shielding telescopic bag 917 overlap with each other, so that multiple groups of contact ropes 919 form a sound absorption area and are located in the lower area of the sliding and opening sound barrier device 4.
