[0001] The present invention relates to the technical field of enclosures, and in particular to a lightweight composite sandwich panel enclosure. Background Art

[0002] At present, with the acceleration of urbanization, highways and viaducts play an important role in urban transportation.

In order to solve this problem, sound insulation enclosures are widely used in the prior art. These enclosures are usually made of metal, glass, concrete or composite materials, and the impact of traffic noise on the surrounding environment is reduced by the application of sound-absorbing and sound-insulating materials.

[0003] Coastal cities often face seasonal typhoons every year. Most existing soundproof enclosures have an arc-shaped top design, which can indeed reflect and absorb noise more effectively. However, due to the large windward area of ​​such enclosures, the aluminum alloy material on its surface is very easy to deform under the action of strong typhoons, thus damaging the sound-absorbing material filled inside and possibly shortening the service life of the soundproof enclosure.

[0007] Preferably, the slide rail device comprises: Two sets of slide rails, the slide rails are fixedly connected to the inner wall of the I-shaped support member; Four groups of pulleys are slidably connected to the slide rails, two groups of pulleys are fixedly connected to the third surface of the sound absorbing screen, and the other two groups of pulleys are fixedly connected to the second surface of the sound absorbing screen.

[0008] Preferably, a fixing rod is provided at the bottom of the wind plate member, and the two ends of the fixing rod are respectively fixedly connected to the bottom of the wind plate member and the three upper surfaces of the sound absorbing screen, the I-shaped support member is provided with a groove on one side of the sound insulation board, and the side walls at both ends of the top of the sound insulation board are fixedly connected with connecting ears, and the connecting ears are slidably connected to the groove.

[0009] Preferably, the path of the channel includes an arc path and a straight path.

[0010] Preferably, the buffer assembly includes a movable rod, buffer grooves for sliding of the movable rod are provided on both sides of the sound-absorbing screen, a trapezoidal block is slidably connected to the sound-absorbing screen at the outlet of the buffer groove, grooves for sliding of the trapezoidal block are provided on both sides of the sound-absorbing screen, a guide rod is fixedly connected to the sound-absorbing screen in the groove, a spring is provided on the outside of the guide rod, the spring is elastically connected to the trapezoidal block, and trapezoidal grooves are provided on the upper and lower sides of the movable rod.

[0011] Preferably, the buffer assembly further comprises: The sealing ring is fixedly sleeved on the bottom of the movable rod, and an air hole is opened at the bottom of the sound-absorbing screen.

[0012] Preferably, the groove is in a sickle shape, and an elastic component is provided between the sound insulation board and the fixing rod, and the elastic component is used to apply external force to the sound insulation board.

[0013] The present invention has at least the following beneficial effects: When encountering strong wind weather, the airflow passes through the upper and lower sides of the wind plate, and the wind plate generates downward pressure under the action of wind force. When the pressure reaches the rated value of the buffer component, the sound absorbing screen 3 and the sound absorbing screen 2 move downward with the slide rail device, thereby reducing the windward area and increasing the overall stability of the device. Under the flow of airflow, the wind plate generates continuous downward pressure, thereby increasing the stability between the I-shaped support and the guardrail; When the downward pressure generated by the wind plate under the action of the typhoon is large enough, the inclined surface of the trapezoidal groove on the movable rod at the bottom of the sound-absorbing screen three cooperates with the inclined surface of the trapezoidal block to make the trapezoidal block move along the groove direction. At this time, the spring will be compressed, and the sound-absorbing screen three will continue to move downward under the push of the wind plate until the trapezoidal groove on the upper side of the movable rod re-engages with the trapezoidal block. At this time, the sound-absorbing screen three and the sound-absorbing screen two are folded. This method can reduce the windward surface of the entire sound-absorbing assembly while cooperating with the downward pressure continuously generated by the wind plate under the typhoon to increase the stability of the entire device; When the downward pressure generated by the wind plate when the air flows through exceeds the rated value of the buffer assembly, the wind plate drives the sound absorbing screen 3 to move downward along the I-shaped support, and the sound insulation board connected to it in rotation also moves downward. The connecting ears on both sides of the sound insulation board move along the arc path and the straight path under the guidance of the groove. Therefore, the sound insulation board will first approach the bottom of the wind plate. As the sound insulation board gradually approaches the bottom of the wind plate, the airflow channel at the bottom of the wind plate becomes narrower, and the airflow will be squeezed, thereby accelerating to flow through the bottom of the wind plate. The airflow path on the arc structure at the top of the wind plate is longer, the airflow speed is higher, and the pressure is lower, while the plane airflow path at the bottom is shorter, the airflow speed is slower, and the sound insulation board approaches the bottom to further accelerate the airflow, resulting in a further reduction in pressure. Therefore, the pressure difference between the top and the bottom increases. Due to the increase in the pressure difference between the top and the bottom, a greater downward force will be generated on the structure, which helps to increase the stability of the entire structure. By designing the channel path to be sickle-shaped, when the wind blows toward the concave surface of the sound insulation board and the wind force reaches a certain value, the sound insulation board will be driven to rotate along the channel. As the sound insulation board approaches the bottom of the wind plate member, the downward pressure generated by the wind plate member under the action of the wind force gradually increases until the sound insulation board reaches the turning point of the sickle-shaped channel. At this time, the wind plate member cooperates with the sound insulation board to generate a strong downward pressure and cooperates with the buffer component to drive the sound absorbing screen three and the sound absorbing screen two to move downward along the I-shaped support member. With this design, it is possible to avoid a smaller wind force driving the wind plate member to press down the sound absorbing screen three to complete the folding action. Instead, when the wind force is at a larger value, the sound insulation board is first driven to rotate, and then the wind plate member is cooperated to drive the sound absorbing screen three and the sound absorbing screen two to fold.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In order to better understand the lightweight composite sandwich panel enclosure provided by the embodiment of the present application, the following first briefly introduces the existing lightweight composite sandwich panel enclosure. The outer layer of the existing sound-absorbing panel is mostly galvanized sheet, aluminum alloy sheet, color steel sheet, pinhole composite aluminum sheet, foam aluminum sheet, aluminum fiber, etc., and the interior is filled with sound insulation materials such as glass wool. When installing this type of sound-absorbing screen, a saddle plate is installed on the crash barrier, and the saddle plates are spaced about two and a half meters apart. Columns are installed on the saddle plates, and finally the sound-absorbing screens for sound insulation are inserted one by one in sequence between the columns, and the sound-absorbing screens are fixed, and an arc-shaped sound-absorbing screen is installed at the top to increase the sound absorption effect. After this type of sound-absorbing screen is assembled, if typhoon weather occurs, it is mainly the columns that cooperate with the saddle plates to play a wind-resistant role. In order to meet the sound insulation standard after assembly, the current sound-absorbing screen is generally more than two meters high. Therefore, such a large windward surface is extremely easy to deform under the action of a strong typhoon, thereby damaging the sound-absorbing material filled inside; The following is a brief overview of the present application scheme. The present application scheme designs the sound-absorbing screen to be foldable, and installs a wind plate member 30 on the top of the top-layer sound-absorbing screen. By utilizing aerodynamics, the wind plate member 30 will generate a downward pressure during typhoon weather. When the downward pressure reaches the rated value, the sound-absorbing screen will fold together, thereby reducing the windward surface, thereby avoiding damage to the sound-absorbing screen under the action of the typhoon. At the same time, the downward pressure generated by the wind plate member 30 can increase the stability of the column, thereby minimizing the shaking of the column under the action of wind.

[0018] Example 1: Please refer to Figure 1 The present invention provides a technical solution: a lightweight composite sandwich panel enclosure, comprising: An I-shaped support member 10, wherein an L-shaped member 11 for connecting to a foundation is provided at the bottom of the I-shaped support member 10; The sound absorbing component 12 is arranged on the I-shaped support member 10, and the sound absorbing component 12 includes: A sound-absorbing screen 121, the sound-absorbing screen 121 is fixedly connected to the lower inner wall of the I-shaped support 10, a sound-absorbing screen 2 122 and a sound-absorbing screen 3 123 are arranged on the top of the sound-absorbing screen 121, a slide rail device 20 is arranged on the I-shaped support 10, the sound-absorbing screen 2 122 and the sound-absorbing screen 3 123 are slidably connected to the I-shaped support 10 through the slide rail device 20, the sound-absorbing screen 1 121, the sound-absorbing screen 2 122 and the sound-absorbing screen 3 123 are arranged in sequence from bottom to top, the top of the sound-absorbing screen 3 123 is rotatably connected with a sound insulation board 124, the sound insulation board 124 is arc-shaped, the top of the sound-absorbing screen 3 123 is provided with a wind plate 30, the wind plate 30 can generate downward pressure when air flows through, and a buffer component 40 is arranged between the sound-absorbing screen 3 123 and the sound-absorbing screen 1 121; It should be noted that when encountering strong winds, the airflow passes through the upper and lower sides of the wind plate member 30, and the wind plate member 30 generates downward pressure under the action of wind. When the pressure reaches the rated value of the buffer assembly 40, the sound absorbing screen three 123 and the sound absorbing screen two 122 cooperate with the slide rail device 20 to move downward, thereby reducing the windward area and increasing the overall stability of the device. Under the flow of air, the wind plate member 30 generates continuous downward pressure, thereby increasing the stability between the I-beam support member 10 and the guardrail.

[0019] Further as Figure 4 and Figure 5As shown, it is worth specifically explaining that the two sides of the second sound-absorbing screen 122 are symmetrically provided with a slide groove 51, and the driving member includes a gear 52, and the gear 52 is rotatably connected to the second sound-absorbing screen 122 located in the middle of the slide groove 51, and the two sides of the gear 52 are respectively meshed with a gear rod 1 53 and a gear rod 2 54, and the top of the gear rod 1 53 is fixedly connected to the surface of the third sound-absorbing screen 123, and the bottom of the gear rod 2 54 is fixedly connected to the surface of the first sound-absorbing screen 121; It should be noted that when the sound-absorbing screen three 123 moves downward, the gear rod one 53 fixedly connected to the surface of the sound-absorbing screen three 123 will push the gear 52 to rotate, and the gear 52 drives the gear rod two 54 to rotate. Since the sound-absorbing screen one 121 is fixedly connected to the I-shaped support 10, the sound-absorbing screen one 121 and the sound-absorbing screen three 123 make a synchronous inward movement with the sound-absorbing screen two 122 as a reference. This design allows the sound-absorbing screen three 123 and the sound-absorbing screen two 122 to move downward at the same time.

[0020] Further as Figure 6 As shown, it is worth to explain in detail that the slide rail device 20 includes: Two sets of slide rails 21, the slide rails 21 are fixedly connected to the inner wall of the I-shaped support member 10; Four groups of pulley members 22, wherein the pulley members 22 are slidably connected to the slide rails 21, wherein two groups of pulley members 22 are fixedly connected to the surface of the third sound absorbing screen 123, and the other two groups of pulley members 22 are fixedly connected to the surface of the second sound absorbing screen 122; It should be noted that by arranging pulley members 22 on the surfaces of the sound absorbing screen three 123 and the sound absorbing screen two 122, when the sound absorbing screen three 123 and the sound absorbing screen two 122 move along the direction of the I-beam support 10, the pulley members 22 cooperate with the slide rails 21 to enable the sound absorbing screen three 123 and the sound absorbing screen two 122 to slide stably and avoid deviation.

[0021] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the cross-sectional shape of the wind plate member 30 includes a top arc surface and a bottom linear surface, a fixing rod 31 is provided at the bottom of the wind plate member 30, the top of the fixing rod 31 is fixedly connected to the wind plate member 30, the bottom of the fixing rod 31 is fixedly connected to the upper surface of the sound absorbing screen 123, the I-shaped support member 10 is provided with a groove 61 on one side of the sound insulation board 124, and the side walls at both ends of the top of the sound insulation board 124 are fixedly connected with connecting ears 62, and the connecting ears 62 are slidably connected to the groove 61; It should be noted that when it is in typhoon weather, the wind plate member 30 with an arc-shaped top and a straight bottom has a lower pressure where the wind speed is faster when wind passes through. At the top of the wind plate member 30, that is, the semicircular arc part, the wind speed is faster and the pressure is lower, while at the bottom, that is, the straight part, the wind speed is slower and the pressure is higher. In this way, since the wind speed is faster and the pressure is lower at the top, and the wind speed is slower and the pressure is higher at the bottom, a pressure difference from top to bottom will be generated as a whole, thereby forming a downward pressure. Therefore, the wind plate member 30 will apply a downward pressure to the sound absorbing screen three 123 through the fixing rod 31 fixedly connected thereto during typhoon weather. When the pressure on the sound absorbing screen three 123 reaches a certain value of the buffer assembly 40, the sound absorbing screen three 123 will move downward along the I-shaped support member 10, thereby completing the folding. At the same time, the sound insulation board 124 rotatably connected to the sound absorbing screen three 123 will also move accordingly, and the fixedly connected connecting ears 62 on both sides of the sound insulation board 124 can change the moving trajectory of the sound insulation board 124 along the path of the groove 61.

[0022] Further as Figure 7 , Figure 8 and Fig. 9 As shown, it is worth specifically explaining that the buffer assembly 40 includes a movable rod 41, the movable rod 41 is fixedly connected to the bottom of the sound-absorbing screen three 123, the sound-absorbing screen one 121 is provided with buffer grooves 42 on both sides for the movable rod 41 to slide, the sound-absorbing screen one 121 is slidably connected with a trapezoidal block 43 at the exit of the buffer groove 42, the sound-absorbing screen one 121 is provided with grooves on both sides for the trapezoidal block 43 to slide, the sound-absorbing screen one 121 is located in the groove and is fixedly connected with a guide rod 44, a spring 45 is arranged on the outside of the guide rod 44, one end of the spring 45 is fixedly connected to the trapezoidal block 43, and the other end of the spring 45 is fixedly connected to the sound-absorbing screen one 121, and the movable rod 41 is provided with trapezoidal grooves 46 on the upper and lower sides; It should be noted that when the downward pressure generated by the wind plate member 30 under the action of a typhoon is large enough, the inclined surface of the trapezoidal groove 46 on the movable rod 41 at the bottom of the sound-absorbing screen three 123 cooperates with the inclined surface of the trapezoidal block 43 to make the trapezoidal block 43 move along the direction of the groove. At this time, the spring 45 will be compressed, and the sound-absorbing screen three 123 continues to move downward under the push of the wind plate member 30 until the trapezoidal groove 46 on the upper side of the movable rod 41 re-engages with the trapezoidal block 43. At this time, the sound-absorbing screen three 123 and the sound-absorbing screen two 122 are folded. This method can reduce the windward surface of the entire sound-absorbing assembly 12 while cooperating with the downward pressure continuously generated by the wind plate member 30 under the typhoon to increase the stability of the entire device.

[0023] Further as Fig. 9 As shown, it is worth to explain in detail that the buffer component 40 also includes: A sealing ring 47, wherein the sealing ring 47 is fixedly sleeved on the bottom of the movable rod 41, and an air hole 48 is opened at the bottom of the sound absorbing screen 121; It should be noted that when the movable rod 41 moves downward along the buffer groove 42 in the sound-absorbing screen 1 121, the sealing ring 47 at the bottom of the movable rod 41 can discharge the air in the buffer groove 42 through the air hole 48 at the bottom of the sound-absorbing screen 1 121. The movable rod 41 cooperates with the sealing ring 47 and the air hole 48 to prevent the movable rod 41 from falling quickly, thereby preventing the sound-absorbing screen 3 123 and the sound-absorbing screen 2 122 from being damaged due to excessive speed during the falling process.

[0024] Further as Figure 1 As shown, it is worth explaining in detail that a connecting piece 81 is provided at the bottom of the I-beam support 10, and the connecting piece 81 is fixedly connected to the L-shaped piece 11 by bolts. By fixing the connecting piece 81 at the bottom of the I-beam support 10, the connecting piece 81 cooperates with the L-shaped piece 11 to increase the stability between the I-beam support 10 and the crash barrier.

[0025] According to the above embodiment, this solution also has a second embodiment: further as Fig.10 and Fig.12 As shown, it is worth to explain in detail that the path of the groove 61 includes an arc path and a straight path; It should be noted that, by designing the path of the groove 61 as a combination of an arc path and a straight path, when the downward pressure generated by the wind plate member 30 when the airflow passes through exceeds the rated value of the buffer assembly 40, the wind plate member 30 drives the sound absorbing screen 3 123 to move downward along the I-shaped support member 10, and at the same time, the sound insulation board 124 rotatably connected thereto also moves downward, and the connecting ears 62 on both sides of the sound insulation board 124 move along the arc path and the straight path under the guidance of the groove 61, so the sound insulation board 124 will first approach the bottom of the wind plate member 30, and as the sound insulation board 124 gradually approaches the wind plate At the bottom of the wind plate member 30, the air flow channel at the bottom of the wind plate member 30 becomes narrower, and the air flow will be squeezed, thereby accelerating to flow through the bottom of the wind plate member 30. The air flow path on the arc structure on the top of the wind plate member 30 is longer, the air flow speed is higher, and the pressure is lower, while the plane air flow path at the bottom is shorter, and the air flow speed is slower. In addition, the sound insulation board 124 is close to the bottom to further accelerate the air flow, resulting in a further decrease in pressure. Therefore, the pressure difference between the top and the bottom increases. Due to the increase in the pressure difference between the top and the bottom, a greater downward force is generated on the structure, which helps to increase the stability of the entire structure.

[0026] According to the above embodiment, this solution also has embodiment 3: further as follows Fig.11 As shown, it is worth to explain in detail that the groove 61 is in a sickle shape, and an elastic component 70 is arranged between the sound insulation board 124 and the fixing rod 31; It should be noted that, by designing the path of the groove 61 to be sickle-shaped, when the wind blows towards the concave surface of the sound insulation board 124 and the wind force reaches a certain value, the sound insulation board 124 will be driven to rotate along the groove 61. As the sound insulation board 124 approaches the bottom of the wind plate member 30, the downward pressure generated by the wind plate member 30 under the action of the wind force gradually increases until the sound insulation board 124 reaches the turning point of the sickle-shaped groove 61. At this time, the wind plate member 30 cooperates with the sound insulation board 124 to generate a strong downward pressure and cooperates with the buffer assembly 40 to drive the sound absorbing screen three 123 and the sound absorbing screen two 122 to move downward along the I-beam support member 10. With this design, it is possible to avoid a smaller wind force driving the wind plate member 30 to press down the sound absorbing screen three 123 to complete the folding action. Instead, when the wind force is at a larger value, the sound insulation board 124 is first driven to rotate, and then the wind plate member 30 is cooperated to drive the sound absorbing screen three 123 and the sound absorbing screen two 122 to fold.

[0027] Further as Fig.11 As shown, it is worth to explain in detail that the elastic component 70 includes: An arc-shaped round rod 71, the end of which is fixedly connected to the convex surface of the sound insulation board 124, the arc-shaped round rod 71 is slidably connected to the fixed rod 31, a vortex spring 72 is sleeved on the arc-shaped round rod 71, one end of the vortex spring 72 is fixedly connected to the convex surface of the sound insulation board 124, and the other end of the vortex spring 72 is fixedly connected to the surface of the fixed rod 31; It should be noted that when the wind force increases and continues to blow from the concave surface of the sound insulation board 124, the arc-shaped round rod 71 on the sound insulation board 124 will compress the vortex spring 72. As the wind force increases, the vortex spring 72 is continuously compressed until the connecting ears 62 on both sides of the sound insulation board 124 reach the inflection point of the groove 61.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, all of which fall within the scope of protection of the present invention.
