Description

Technical Field

[0001] The present invention relates to the technical field of road sound barriers, and in particular to a ventilation and heat dissipation type fully enclosed sound barrier. Background Art

[0002] A sound barrier is a structure used to isolate and reduce noise transmission. It is usually installed around busy roads, railways or industrial areas to reduce the impact of traffic noise on the surrounding environment and residents' lives. The height, thickness and material selection of the sound barrier will be adjusted according to the specific noise control needs and environmental conditions. The working principle of the sound barrier is mainly to reduce the noise level by reflecting and absorbing sound waves. After the sound barrier is set up, the sound will be blocked during the transmission process, thereby reducing the noise entering the residential area or other places where a quiet environment is required.

[0003] Referring to the Chinese patent document with the authorization announcement number CN102182152B, a full-shadow sound barrier for urban express lanes and tunnel entrances is disclosed, which is composed of a main frame of the sound barrier formed by a portal arc-shaped steel arch frame arranged in the upper space of the road surface, rigid tie rods connecting adjacent arch frames and cross support rods, and purlins are arranged on the main frame. At the same time, with the purlins arranged on the main frame as support, sound absorbers, ventilation and smoke exhaust parts, sound absorbers, lighting parts, sound absorbers and lighting parts are arranged at intervals along the central axis of the sound barrier symmetrically to the left and right sides until the contact surface of the crash wall arranged on the road surface, thereby forming a full-shadow sound barrier structure that is fully or semi-enclosed to the road and can completely isolate direct sound.

[0004] In response to the above-mentioned related technologies, this patent has a ventilation and smoke exhaust section on the upper part of the sound barrier, which discharges the smoke and dust inside the sound barrier by natural ventilation, and this opening is also the outlet for the sound inside the sound barrier to leak out. The noise reduction performance of the sound barrier may be reduced. At the same time, if the sound barrier is long and the temperature of the external environment is high due to direct sunlight, it is easy to cause the temperature inside the sound barrier to be high. Summary of the invention

[0005] In view of this, the present invention provides a ventilation and heat dissipation type fully enclosed sound barrier, which aims to solve the problem that it is difficult to dissipate heat from the sound barrier and that the noise reduction of the sound barrier is affected when the sound barrier is ventilated and heat is dissipated.

[0006] In order to solve the above technical problems, the present invention provides a ventilation and heat dissipation type fully enclosed sound barrier, comprising a plurality of groups of partitions arranged at intervals vertically and a plurality of cover plates fixedly connected to the top of a group of partitions, wherein the cover plates are arranged in a herringbone shape, a plurality of connection shells are arranged at intervals above the cover plates, the bottom of the connection shells is communicated with the space below the cover plates, an air outlet chamber is arranged on the left and right sides of the interior of the connection shells, and an air outlet is arranged on the top of the air outlet chamber;

[0007] An exhaust pipe is fixedly arranged on the cover plate, and the exhaust pipe extends from the bottom of the cover plate to the top of the cover plate and extends into the lower part of the air outlet chamber. An air inlet is provided at the highest point of the exhaust pipe located at the lower part of the cover plate, a sound absorbing layer is provided on the inner side wall connecting the front and rear sides of the shell, and an air inlet hole is provided on the front and rear side walls connecting the shell, and a heat absorbing material is provided on the upper surface of the exhaust pipe located above the cover plate.

[0008] By adopting the above technical scheme, when the sound barrier is directly exposed to the sun, the heat can be absorbed by the heat-absorbing material on the exhaust pipe, thereby reducing the heat transferred to the sound barrier, so as to reduce the temperature inside the sound barrier. At the same time, the temperature of the exhaust pipe increases, causing the air in the exhaust pipe to expand, thereby accelerating the flow of gas in the exhaust pipe, so that the hot air flow under the cover plate enters the exhaust pipe from the air inlet, and enters the air outlet chamber along the exhaust pipe and is discharged from the air outlet. At this time, the gas in the sound barrier is supplemented by entering the connecting shell through the air inlet and then entering the sound barrier, which is conducive to discharging the high-temperature airflow in the sound barrier and reducing the temperature in the sound barrier. The sound-absorbing layer is arranged close to the air inlet to absorb the sound, thereby reducing the temperature in the sound barrier while ensuring the noise reduction effect.

[0009] Optionally, guide pipes are fixedly provided on the front and rear sides of the lower surface of the cover plate respectively. The guide pipes are arranged obliquely, the highest end of the guide pipes is located at the bottom of the connecting shell, the lowest end of the guide pipes is arranged close to the partition, and a fan is arranged in the guide pipes.

[0010] By adopting the above technical solution, the setting of the guide pipe can guide and disperse the airflow entering the sound barrier. The forward and reverse rotation of the fan can accelerate the speed of air intake into the sound barrier on the one hand, and on the other hand, it can accelerate the discharge of smoke when a large amount of smoke is generated when an accident occurs on the road.

[0011] Optionally, venetian blinds are respectively provided between the opposite inner sides of the two sound absorbing layers, the venetian blinds located on the front side extend downward from front to back, and the venetian blinds located on the rear side extend upward from front to back.

[0012] By adopting the above technical solution, the arrangement of the venetian blind can guide the airflow entering the connection shell.

[0013] Optionally, a heat absorbing material is provided on the outer side wall of the connecting shell close to the air outlet chamber.

[0014] By adopting the above technical solution, the setting of the heat-absorbing material on the outer wall of the air outlet chamber can increase the temperature of the air outlet chamber, thereby accelerating the flow of air in the air outlet chamber, so as to discharge the high-temperature gas and reduce the temperature in the sound barrier.

[0015] Optionally, a plurality of smoke exhaust mechanisms are provided above the cover plate for exhausting smoke when an accident occurs in the sound barrier.

[0016] By adopting the above technical solution, when a large amount of smoke is generated due to an accident on the road, the setting of the smoke exhaust mechanism can speed up the exhaust of the smoke, thereby ensuring the air quality within the sound barrier to a certain extent.

[0017] Optionally, each of the smoke exhaust mechanisms includes a supporting shell, a smoke exhaust fan, a connecting rod, a sliding rod, two rotating plates and two connecting plates. The supporting shell is fixedly connected to the connecting shell, the smoke exhaust fan is installed in the supporting shell, the connecting rod is fixedly connected to the top center of the smoke exhaust fan and extends in the up and down directions, the sliding rod is threadedly connected to the connecting rod and the sliding rod extends in the front and back directions, the rotating plate is hinged to the front and back sides of the upper surface of the connecting shell, and the sliding rod is slidably connected between the relative inner sides of the two rotating plates, the connecting plate is fixedly connected to the left and right sides of the upper surface of the connecting shell, the two rotating plates and the two connecting plates form a triangular prism and are connected to the inside of the connecting shell.

[0018] By adopting the above technical solution, when it is necessary to speed up the discharge of smoke in the sound barrier, the smoke exhaust fan is started to make the smoke flow upward. When the smoke exhaust fan rotates, it drives the connecting rod to rotate. Since the connecting rod is threadedly connected to the sliding rod, the connecting rod drives the sliding rod to move upward when it rotates. As the sliding rod moves, the sliding rod pushes the rotating plates on both sides to open, thereby increasing the smoke exhaust port, which is beneficial to the discharge of smoke in the sound barrier.

[0019] Optionally, a pull rope is provided between the rotating plate and the venetian blind.

[0020] By adopting the above technical solution, the rotating plate can pull the blind to rotate through the pull rope when it is opened, thereby shielding the sound absorbing layer on one side of the blind, reducing smoke pollution to the sound absorbing layer, and extending the service life of the sound absorbing layer.

[0021] Optionally, a light-transmitting area and a light-shielding area are provided on the partition.

[0022] By adopting the above technical solution, the setting of the light-transmitting area and the light-shielding area is conducive to reducing light pollution while ensuring the light within the sound barrier, thereby improving road safety.

[0023] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects:

[0024] 1. When the sound barrier is directly exposed to the sun, the heat absorbing material on the exhaust pipe can absorb the heat, thereby reducing the heat transferred to the sound barrier, so as to reduce the temperature inside the sound barrier. At the same time, the temperature of the exhaust pipe increases, causing the air in the exhaust pipe to expand, thereby accelerating the flow of gas in the exhaust pipe, so that the hot air flow under the cover plate enters the exhaust pipe from the air inlet, and enters the exhaust chamber along the exhaust pipe and is discharged from the outlet.

[0025] 2. When smoke is generated in the event of a road accident, the smoke exhaust port is enlarged by rotating the rotating plate so that the smoke can be discharged quickly. At the same time, the rotating plate rotates to drive the pull rope to drive the blinds to rotate, thereby protecting the sound-absorbing layer and extending the service life of the sound-absorbing layer;

[0026] 3. The setting of the fan in the guide duct can speed up the air supply when supplying air to the sound barrier, and can also speed up the smoke exhaust when exhausting smoke. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 5 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0034] Reference Figure 1A ventilation and heat dissipation type fully enclosed sound barrier comprises a plurality of baffles 1, a plurality of cover plates 11 fixedly connected to a group of baffles 1, a support rod 111, a connection shell 12 fixedly connected to the upper surface of the cover plate 11, an exhaust pipe 15 fixedly connected to the cover plate 11, and an exhaust chamber 13 arranged on the left and right sides of the connection shell 12. In this embodiment, for the convenience of description, the length direction of the baffle 1 is defined as the left-right direction, the width direction is the front-back direction, and the height direction is the up-down direction.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , the partitions 1 are vertically arranged on a horizontal plane, each group of partitions 1 are arranged at intervals, and multiple groups of partitions 1 are connected to each other and arranged on both sides of the road. The partitions 1 on each side are reinforced by support rods 111. In this embodiment, two support rods 111 are provided on the partition 1, and the partition 1 between the two support rods 111 is a shading area 61. The partitions 1 on the upper and lower sides of the shading area 61 are set as light-transmitting areas 6. The upper surface of each group of partitions 1 is fixedly connected with a herringbone cover plate 11, and the multiple cover plates 11 are also reinforced by support rods 111. The connecting shell 12 is spaced in the middle of the upper surface of the cover plate 11, and the front and rear sides of the connecting shell 12 are respectively provided with sound-absorbing layers 17, and the front and rear side walls of the connecting shell 12 are respectively provided with sound-absorbing layers 17. An air inlet 16 is provided, and the connecting shell 12 is connected with the space below the cover plate 11. The exhaust pipe 15 extends from the lower surface of the cover plate 11 to the upper surface of the cover plate 11 and extends into the air outlet chamber 13. The top wall of the exhaust pipe 15 located on the upper surface of the cover plate 11 is coated with heat-absorbing material, and the left and right walls of the connecting shell 12 are coated with heat-absorbing material to accelerate the flow of air in the exhaust pipe 15 and the air outlet chamber 13. The exhaust pipe 15 located on the lower surface of the cover plate 11 is provided with an air inlet 16 at the highest position of the cover plate 11 to facilitate the entry of high-temperature airflow. The top of the air outlet chamber 13 is provided with an air outlet 14, and a baffle 141 fixedly connected to the connecting shell 12 is provided above the air outlet 14 to improve the noise reduction effect of the sound barrier.

[0036] When it is necessary to discharge the high-temperature airflow in the sound barrier, the sun shines directly on the exhaust pipe 15, and the heat-absorbing material on the exhaust pipe 15 begins to absorb heat, thereby reducing the heat to the inside of the sound barrier. At the same time, the temperature rises, which increases the air temperature in the exhaust pipe 15, thereby accelerating the flow of gas in the exhaust pipe 15. The high-temperature airflow comes under the cover plate 11, enters from the air inlet 16 and quickly flows into the air outlet chamber 13, and then is discharged to the outside from the air outlet 14. The outside air enters from the air inlet 18 to realize ventilation of the sound barrier, so as to reduce the temperature in the sound barrier. At the same time, the sound-absorbing layer 17 is arranged at the air inlet 18, and the arrangement of the baffle 141 above the air outlet 14 is conducive to improving the noise reduction function of the sound barrier.

[0037] Reference Figure 3 and Figure 4 , Venetian blinds 3 are respectively provided on the front and rear sides of the connecting shell 12, and the relatively inner sides of the two Venetian blinds 3 are heavier than the opposite outer sides of the two Venetian blinds 3, thereby realizing the inclined setting of the Venetian blinds 3. After entering from the air inlet 18, the air passes downward through the Venetian blinds 3 to the bottom of the cover plate 11. Two guide pipes 2 are provided at the connecting point between each connecting shell 12 and the bottom of the cover plate 11. The guide pipes 2 are fixedly connected to the lower surface of the cover plate 11, and the guide pipes 2 extend from the middle of the cover plate 11 to the front and rear sides of the cover plate 11 so as to evenly disperse the incoming air. A fan 21 is installed in the guide pipe 2. The direction of the airflow can be changed by the forward and reverse rotation of the fan 21. When replenishing air into the sound barrier, the speed can be accelerated by the fan 21. If an accident occurs in the sound barrier and a large amount of smoke is generated, the speed of smoke discharge can be accelerated by the fan 21.

[0038] Reference Figure 2 , Figure 4 and Figure 5 , a plurality of smoke exhaust mechanisms 4 for exhausting smoke are arranged above the cover plate 11, and the smoke exhaust mechanisms 4 are arranged at the connection shell 12. When an accident occurs in the sound barrier and a large amount of smoke is generated, the smoke in the sound barrier can be quickly discharged through the smoke exhaust mechanisms 4. Each smoke exhaust mechanism 4 includes a support shell 41, a smoke exhaust fan 42, a connecting rod 43, a sliding rod 44, two rotating plates 45 and two connecting plates 46. The support shell 41 is fixedly connected to the inner side wall of the connection shell 12, and the smoke exhaust fan 42 is installed inside the connection shell 12. The connecting rod 43 is fixedly connected to the center of the upper surface of the smoke exhaust fan 42 and extends in the up-down direction, so that the connecting rod 43 rotates together with the smoke exhaust fan 42. A thread is provided on the connecting rod 43, and the sliding rod 44 is threadedly connected to the connecting rod 43 and extends in the front-back direction. The two rotating plates 45 and the two connecting plates 46 form a triangular prism shape, and the cavity formed by them is connected to the inside of the connecting shell 12. The two rotating plates 45 are hinged to the front and rear sides of the upper surface of the connecting shell 12 and are arranged obliquely. The connecting plates 46 are fixedly connected to the left and right sides of the connecting shell 12. The relative inner walls of the two rotating plates 45 are provided with sliding grooves 451 for the sliding rod 44 to slide. When the sliding rod 44 moves upward, it can push the two rotating plates 45 to rotate so that the connecting shell 12 is connected to the outside world, thereby increasing the smoke exhaust port to facilitate the rapid discharge of smoke.

[0039] If an accident occurs and rapid smoke exhaust is required, the smoke exhaust fan 42 is first started to draw the smoke upward. As the smoke exhaust fan 42 rotates, the smoke exhaust fan 42 drives the connecting rod 43 to rotate. The connecting rod 43 causes the sliding rod 44 to move upward during the rotation. The sliding rod 44 pushes the rotating plates 45 at both ends of the sliding rod 44 to rotate during the upward movement. Then the smoke can be quickly discharged from the space created by the rotation of the rotating plates 45. After the sliding rod 44 moves to disengage from the thread on the connecting rod 43, the rotating plates 45 stop rotating. After the smoke is discharged, the smoke exhaust fan 42 is reversed. Under the action of the sliding rod 44's own gravity, the sliding rod 44 moves downward along the thread on the connecting rod 43 and rotates with the rotating plate 45, so that the rotating plate 45 re-shields the interior of the connecting shell 12.

[0040] Reference Figure 4 A pull cord 5 is connected between the rotating plate 45 and the venetian blind 3. When the rotating plate 45 rotates, the pull cord 5 can pull the venetian blind 3 to change the angle of the venetian blind 3, so as to shield the sound absorbing layer 17, thereby reducing the adverse effect of smoke on the sound absorbing layer 17 during smoke exhaust, so as to extend the service life of the sound absorbing layer 17.

[0041] The implementation principle of a ventilation and heat dissipation type fully enclosed sound barrier in an embodiment of the present invention is:

[0042] When the external sunlight directly shines on the sound barrier and causes the temperature inside the sound barrier to rise, the heat is absorbed by the heat-absorbing material on the exhaust pipe 15, thereby reducing the heat transferred to the inside of the sound barrier. At the same time, the high-temperature airflow inside the sound barrier gathers at the upper part of the sound barrier and enters the exhaust pipe 15 from the air inlet 16. The heat-absorbing material increases the temperature inside the exhaust pipe 15, thereby accelerating the flow of air. The high-temperature airflow enters the air outlet cavity and is discharged from the air outlet 14. At the same time, the airflow enters from the air inlet 18, passes through the louver 3, and then enters the sound barrier, and is evenly dispersed to the inside of the sound barrier through the guide pipe 2, thereby realizing air circulation.

[0043] When an accident occurs on the road and a large amount of smoke is generated, the smoke exhaust fan 42 is started to exhaust the smoke. The smoke exhaust fan 42 drives the connecting rod 43 to rotate, thereby causing the sliding rod 44 to move upward. The upward movement of the sliding rod 44 drives the rotating plate 45 to rotate, thereby forming a smoke exhaust channel to allow the smoke to be discharged quickly. When the rotating plate 45 rotates, it drives the pull rope 5 to rotate the blinds 3, thereby protecting the sound absorbing layer 17.

[0044] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
