Abstract
Description
Technical Field
[0001] This invention relates to the field of sound insulation equipment technology, and more specifically, to a fully enclosed sound barrier based on building energy-saving sound insulation material panels. Background Technology
[0002] Building energy-saving sound insulation material panels are a new type of material with excellent sound insulation performance and energy-saving characteristics. They can be widely used in various sound insulation and noise reduction equipment. However, existing fully enclosed sound barriers do not widely use building energy-saving sound insulation material panels at the material level. Traditional sound barrier panels often have single functions or focus on sound insulation while neglecting heat insulation, making it difficult to balance structural and weather resistance performance. In addition, existing fully enclosed sound barrier structures also face many technical challenges. To meet fire protection and ventilation requirements, fully enclosed structures must be equipped with smoke exhaust vents, but the opening of the smoke exhaust vents inevitably causes "sound leakage," greatly weakening the overall sound insulation effect. Currently, the smoke exhaust vent design in existing technology is simple and open, lacking effective noise reduction design, becoming a key weakness in noise leakage. Therefore, how to reasonably install building energy-saving sound insulation material panels inside the fully enclosed sound barrier and its smoke exhaust vents is a very important technical issue.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:
[0016] This invention discloses a fully enclosed sound barrier based on building energy-saving and sound-insulating material panels. The panels are combined with a portal steel frame structure as the enclosure, reducing traffic noise, conforming to green building principles, and achieving a balance between environmental protection and energy conservation. A self-opening smoke exhaust structure is installed at the normally closed smoke exhaust outlet of the portal steel frame structure. Under normal conditions, the self-opening smoke exhaust structure keeps the normally closed smoke exhaust outlet sealed, thereby improving the building's energy-saving and sound-insulating effect. In the event of a fire inside the fully enclosed sound barrier generating significant smoke, the self-opening smoke exhaust structure releases the seal on the normally closed smoke exhaust outlet, allowing the smoke to escape through it, effectively ensuring safety in emergency situations. Furthermore, a normally open smoke exhaust outlet can be optionally installed at the top of the portal steel frame structure, depending on actual needs, to meet the safety requirements of different environments. When a normally open smoke exhaust outlet is installed, a ventilation and noise reduction structure is connected to it.

Detailed Implementation
[0034] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.
[0036] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.
[0037] The following is in conjunction with the appendix Figure 1-14 The present invention will be described in further detail below.
[0038] Example 1: As Figures 1-14As shown, a fully enclosed sound barrier based on building energy-saving sound insulation material panels includes: building energy-saving sound insulation material panels 110, a portal steel frame structure 130, and a self-opening smoke exhaust structure 140. Multiple building energy-saving sound insulation material panels 110 are provided, and these panels are respectively installed on the sides and top of the portal steel frame structure 130. The self-opening smoke exhaust structure 140 is installed in the normally closed smoke exhaust port of the portal steel frame structure 130. When a fire occurs inside the fully enclosed sound barrier and generates a large amount of smoke, the self-opening smoke exhaust structure 140 releases the seal on the normally closed smoke exhaust port or auxiliary smoke exhaust port, allowing the smoke to be discharged through the normally closed smoke exhaust port or auxiliary smoke exhaust port. The number and installation location of the self-opening smoke exhaust structure 140 can be selected according to the actual environment.
[0039] The working principle and technical effects of the above scheme are as follows:
[0040] In a fully enclosed sound barrier based on building energy-saving sound insulation material panels of the present invention, building energy-saving sound insulation material panels 110 are installed on the sides and top of a portal steel frame structure 130, forming a fully enclosed spatial structure. When noise is generated and propagates to the outside of the sound barrier, the noise first comes into contact with the building energy-saving sound insulation material panels 110 on the sides and top. Due to its special structure and material properties, the building energy-saving sound insulation material panels 110 cause the sound waves to continuously change their propagation direction inside the material panel, and rub against the pore walls and fibers of the material, gradually converting sound energy into heat energy. Thus, most of the noise is consumed inside the material panel, effectively reducing the noise transmitted outside the sound barrier. This invention reduces noise intensity and the propagation of noise to the outside, achieving the sound insulation function of a fully enclosed sound barrier. Multiple energy-saving sound insulation material panels 110 are installed on the sides and top of the portal steel frame structure 130, forming a comprehensive sound barrier. The fully enclosed design significantly improves sound insulation compared to traditional semi-enclosed or open sound barriers. The portal steel frame structure 130 provides a stable support frame for the energy-saving sound insulation material panels 110, possessing high strength and rigidity, capable of withstanding the weight of the panels and the effects of external environmental factors (such as wind and earthquake forces), ensuring the overall stability of the sound barrier structure.
[0041] This invention discloses a fully enclosed sound barrier based on building energy-saving and sound-insulating material panels. Under normal conditions, the fully enclosed sound barrier functions normally. In the absence of emergencies such as fires, the self-opening smoke exhaust structure 140 is in a closed state, tightly installed at the normally closed smoke exhaust port of the portal steel frame structure 130 or the auxiliary smoke exhaust port of the support plate 123, preventing uncontrolled entry of outside air into the sound barrier while ensuring that the sound insulation and energy-saving performance of the sound barrier are not affected. In the event of a fire, when a fire occurs inside the fully enclosed sound barrier and generates a large amount of smoke, the self-opening smoke exhaust structure 140 will receive a corresponding trigger signal. Upon receiving the signal, the self-opening smoke exhaust structure 140 will initiate the unblocking action, opening the normally closed smoke exhaust port or the auxiliary smoke exhaust port. Due to the high temperature and rising characteristics of smoke generated by a fire, the smoke will quickly be discharged to the outside of the sound barrier through the opened normally closed smoke exhaust port or the auxiliary smoke exhaust port, thereby timely reducing the smoke concentration inside the sound barrier and creating favorable conditions for rescue and personnel evacuation.
[0042] In this invention, a fully enclosed sound barrier based on building energy-saving and sound-insulating material panels features a self-opening smoke exhaust structure 140. This structure provides an effective smoke extraction pathway in emergencies such as fires. During a fire, it rapidly exhausts large amounts of smoke, preventing smoke accumulation inside the sound barrier and reducing the risk of smoke asphyxiation, thus ensuring the safety of personnel inside. Under normal conditions, the self-opening smoke exhaust structure 140 seals the normally closed smoke outlets or auxiliary smoke outlets, ensuring the integrity and airtightness of the overall sound barrier structure. Additional openings do not affect the sound insulation or energy-saving performance of the sound barrier. In special circumstances such as fires, it can reliably open to achieve smoke extraction, enhancing the overall reliability of the sound barrier structure through stable performance under different operating conditions. The self-opening smoke exhaust structure 140 provides a dedicated smoke extraction function for emergencies such as fires. The presence of the self-opening smoke exhaust structure 140 ensures that the sound barrier not only meets the requirements of sound insulation and energy saving but also protects the safety of personnel and equipment in emergencies such as fires, improving the applicability and overall performance of the sound barrier.
[0043] Example 2: Figures 1-14As shown, the self-opening smoke outlet structure 140 includes: an assembly frame plate 141 fixedly connected to a normally closed smoke outlet or an auxiliary smoke outlet; two longitudinal smoke outlets 142 extending through the assembly frame plate 141 are opened opposite each other; one end of a normally closed cover plate 143 is movably connected to each of the two longitudinal smoke outlets 142; the upper inner side of the two normally closed cover plates 143 is connected to a self-opening actuator 144 connected in the middle of the assembly frame plate 141, so that the closure of the two longitudinal smoke outlets 142 can be released under the control of the self-opening actuator 144. A retaining ridge is fixedly connected to the longitudinal smoke outlet 142; when the normally closed cover plate 143 blocks the longitudinal smoke outlet 142, the lower surface of the normally closed cover plate 143 abuts against the retaining ridge. A transverse sliding shaft 145 is fixedly connected to the outer end of each of the two normally closed cover plates 143; the two transverse sliding shafts 145 are slidably fitted in the transverse sliding grooves within the two longitudinal smoke outlets 142. The self-starting actuator 144 includes: a heating cylinder 1 that is open at the top and closed at the bottom. The heating cylinder 1 is fixed to the middle of the lower surface of the mounting plate 141 by a support frame. A piston disc 2 is slidably connected inside the heating cylinder 1. The heated area formed between the piston disc 2 and the bottom surface of the heating cylinder 1 is filled with a low-boiling-point liquid or solid paraffin. The top of the piston disc 2 is connected to the lower end of the drive shaft 3. The middle part of the drive shaft 3 is slidably fitted in the center hole of the top limiting frame of the heating cylinder 1 and the center hole of the mounting plate 141. The upper end of the drive shaft 3 is connected to the lifting drive plate 4. A linkage frame 5 is rotatably connected to each end of the lifting drive plate 4. The two linkage frames 5 are rotatably connected to the upper ends of the inner side of the two normally closed cover plates 143.
[0044] The working principle and technical effects of the above scheme are as follows:
[0045] This invention discloses a fully enclosed sound barrier based on building energy-saving sound insulation material panels. Under normal conditions, the fully enclosed sound barrier is in normal use. In the absence of emergencies such as fire, the self-opening smoke exhaust structure 140 is completely closed. The normally closed cover plate 143 seals the longitudinal smoke exhaust port 142, and the lower surface of the normally closed cover plate 143 abuts against the retaining rib fixed inside the longitudinal smoke exhaust port 142, ensuring the stability of the seal and preventing outside air from freely entering the sound barrier, thus maintaining the sound insulation and energy-saving performance of the sound barrier. The sliding engagement of the transverse sliding shaft 145 and the transverse sliding groove ensures that the normally closed cover plate 143 is stable in the closed state. At this time, in the heating cylinder 1 of the self-opening actuator 144, the piston disc 2 is in a lower position because the low-boiling-point liquid or solid paraffin filled in the heated zone is at room temperature and no phase change has occurred. The drive shaft 3, lifting drive plate 4, linkage frame 5, and other components are also in a stationary state and do not drive the normally closed cover plate 143.
[0046] In the event of a fire, when a fire occurs inside the fully enclosed sound barrier, the ambient temperature rises sharply. The low-boiling-point liquid or solid paraffin inside the heating cylinder 1 absorbs heat, the low-boiling-point liquid begins to vaporize, and the solid paraffin begins to melt and expand. Since the heating cylinder 1 has an open top, closed bottom, and sealed interior structure, the pressure in the heated area increases, pushing the piston disc 2 to slide upward. The piston disc 2 slides upward, causing the drive shaft 3 connected to it to move upward. The middle part of the drive shaft 3 slides in the center hole of the top limit bracket of the heating cylinder 1 and the center hole of the assembly bracket plate 141, which plays a guiding role. The lifting drive plate 4 connected to the upper end of the drive shaft 3 moves upward accordingly. The linkage frame 5 connected to both ends of the lifting drive plate 4 also moves. The linkage frame 5 is rotatably connected to the upper end of the inner side of the normally closed cover plate 143. As the linkage frame 5 moves, it causes one end of the normally closed cover plate 143 to move upward. The transverse sliding shaft 145 at the other end of the normally closed cover plate 143 slides along the transverse sliding groove, thereby releasing the normally closed cover plate 143 from the longitudinal smoke outlet 142. The smoke generated by the fire can be quickly discharged outside the sound barrier through the longitudinal smoke outlet 142.
[0047] This invention discloses a fully enclosed sound barrier based on building energy-saving sound insulation material panels. In the event of a fire, it does not require additional electrical equipment or power sources for operation. The self-starting actuator 144 utilizes the natural phenomenon of increased ambient temperature during a fire, generating driving force through the phase change of low-boiling-point liquids or solid paraffin to automatically open the normally closed cover 143. This method is unaffected by electrical faults or power source interruptions, significantly improving the system's reliability in emergencies such as fires. For example, even if a fire causes a power system failure, the device can still operate normally, ensuring smoke extraction, and eliminating the need for additional power equipment and related control systems, thus reducing equipment procurement and installation costs. It also reduces the workload and costs of routine maintenance and repair, as there is no need for regular inspection and maintenance of complex power systems. Furthermore, once a fire occurs, the increased ambient temperature causes the low-boiling-point liquids or solid paraffin to rapidly undergo a phase change, generating driving force to open the normally closed cover 143. Compared to systems requiring additional power equipment, this device can respond to fire situations more quickly, promptly expelling smoke and buying more time for rescue and evacuation. The self-opening smoke exhaust structure 140 works in conjunction with the ventilation and noise reduction structure 120 to improve the ventilation and smoke exhaust system of the fully enclosed sound barrier. The self-opening smoke exhaust structure 140, through its ingenious design, achieves the function of automatically opening without additional power in the event of a fire. It has the advantages of high reliability, low cost, and rapid response. At the same time, the overall structure is stable and reasonable, providing effective safety protection and functional improvement measures for the fully enclosed sound barrier.
[0048] Example 3: As Figures 1-14As shown, the heating cylinder 1 is a metal cylinder, and a limiting ring for limiting the lowest position of the piston disc 2 is fixed inside the metal cylinder. Multiple heat-conducting fins 6 are uniformly and fixedly connected around the outer wall of the heating cylinder 1. A conical flow-concentrating ring 18 is also fixedly connected to the outer wall of the heating cylinder 1. The conical flow-concentrating ring 18 covers the outside of the multiple heat-conducting fins 6, and multiple outlet holes are opened longitudinally on the conical flow-concentrating ring 18.
[0049] The working principle and technical effects of the above scheme are as follows:
[0050] In a fully enclosed sound barrier based on building energy-saving sound insulation material panels of the present invention, a limiting ring fixed inside the heating cylinder 1 is used to limit the lowest position of the piston disc 2. Under normal conditions, the limiting ring provides a stable initial position for the piston disc 2, ensuring that all components of the self-starting actuator 144 are in the correct assembly state. The limiting ring can prevent the piston disc 2 from moving excessively downward, avoiding the abnormal position of the piston disc 2 from affecting the normal operation of the self-starting actuator 144, thereby ensuring the stability and reliability of the entire self-starting smoke exhaust structure 140. The heating cylinder 1 is a metal cylinder, and metal itself has good thermal conductivity. Multiple heat-conducting fins 6 are uniformly and fixedly connected around the outer wall of the heating cylinder 1, further increasing the heat dissipation area of the heating cylinder 1. When a fire occurs, the ambient temperature rises, and the heat-conducting fins 6 can quickly absorb the surrounding heat and transfer the heat to the low-boiling-point liquid or solid paraffin inside the heating cylinder 1. Compared to the absence of heat-conducting fins 6, heat transfer is more rapid, allowing low-boiling-point liquids or solid paraffins to undergo phase changes more quickly. This accelerates the response speed of the self-starting actuator 144, enabling the normally closed cover 143 to open more quickly and expel smoke promptly. A conical concentrator ring 18, fixed to the outer wall of the heating cylinder 1, covers the outside of multiple heat-conducting fins 6. During a fire, the rising heat flow is guided by the conical concentrator ring 18, concentrating the heat flow more effectively onto the heat-conducting fins 6. This improves the heat absorption efficiency of the heat-conducting fins 6 and further accelerates the phase change rate of low-boiling-point liquids or solid paraffins inside the heating cylinder 1, shortening the response time of the self-starting actuator 144. Multiple longitudinally formed outlet holes on the conical concentrator ring 18 guide the heat flow to the heat-conducting fins 6 while also ensuring adequate ventilation. The outlet hole allows some heat to be discharged in an orderly manner, and ventilation helps to maintain air circulation around the heating cylinder 1, ensuring that heat can be continuously and effectively transferred to the interior of the heating cylinder 1, so that the self-starting drive 144 can work stably and reliably.
[0051] Example 4: Figures 1-14As shown, the portal steel frame structure 130 has a normally open smoke exhaust vent at its top, which is connected to a ventilation and noise reduction structure 120. This ventilation and noise reduction structure 120 reduces the noise emitted from the smoke exhaust vent. The ventilation and noise reduction structure 120 is primarily responsible for the daily ventilation and noise reduction functions of the sound barrier. The two work together to perfect the ventilation and smoke exhaust system of the fully enclosed sound barrier, enabling it to function effectively in different usage scenarios and meeting various needs in both normal use and emergency situations. For locations with high safety requirements, such as sound barriers around airports and train stations, the ventilation and noise reduction structure 120 handles daily ventilation, while the self-opening smoke exhaust structure 140 provides rapid smoke exhaust during a fire, ensuring the sound barrier functions effectively under various conditions.
[0052] The working principle and technical effects of the above scheme are as follows:
[0053] In this invention, a fully enclosed sound barrier based on building energy-saving sound insulation material panels features a normally open smoke exhaust vent at the top of the portal steel frame structure 130. This vent improves airflow within the sound barrier and facilitates smoke extraction in emergencies. However, airflow noise is generated when air enters or exits the sound barrier through the normally open smoke exhaust vent. A ventilation and noise reduction structure 120 is connected to the normally open smoke exhaust vent. The airflow entering the ventilation and noise reduction structure 120 is continuously consumed, thereby reducing the noise output from the normally open smoke exhaust vent. This ensures ventilation while minimizing noise impact on the surrounding environment. The combination of the ventilation and noise reduction structure 120 and the normally open smoke exhaust vent solves the problem of noise generated during ventilation. By ensuring normal airflow within the sound barrier while reducing ventilation noise, the entire sound barrier system achieves a good balance between ventilation and sound insulation, further enhancing the sound insulation performance of the sound barrier. This sound barrier not only possesses the main functions of sound insulation and energy saving, but also achieves ventilation and smoke exhaust functions through the ventilation and noise reduction structure 120 and normally open smoke exhaust vents. This makes the sound barrier suitable for a variety of different scenarios, such as sound insulation and noise reduction along highways and railways, improving the practicality and applicability of the sound barrier and meeting the diverse needs of different users.
[0054] Example 5: Figures 1-14As shown, the ventilation and noise reduction structure 120 includes: a sound-absorbing component 121, a sound-damping component 122, and a support plate 123; the auxiliary smoke outlet of the support plate 123 can be equipped with a self-opening smoke outlet structure 140; the portal steel frame structure 130 is an inverted U-shaped structure, with a normally open smoke outlet located in the middle of the top of the portal steel frame structure 130; two sound-absorbing components 121 are arranged opposite each other on both sides of the top of the smoke outlet, and the support plate 123 is fixedly connected to the top of the two sound-absorbing components 121, forming a through-type ventilation channel along the length of the portal steel frame structure 130 between the support plate 123 and the two sound-absorbing components 121; multiple sound-damping components 122 are installed in the through-type ventilation channel. The building energy-saving sound insulation material board 110, the sound-absorbing component 121, the sound-damping component 122, and the support plate 123 are all one or a combination of aluminum honeycomb perforated sound-absorbing panels, flame-retardant foam aluminum sound-absorbing panels, or mineral wool sound-absorbing panels. Multiple sound-damping elements 122 are staggered and arranged on the lower surface of the support plate 123 and the upper surface of the normally open exhaust port, so that abrupt interfaces are formed between the multiple sound-damping elements 122. Each sound-damping element 122 has a first air guide surface, and the first air guide surfaces of the multiple sound-damping elements 122 are staggered. The sound-absorbing element 121 is a louver structure with multiple blades, and the multiple blades of the sound-absorbing element 121 have second air guide surfaces, with an angle between the second air guide surfaces and the first air guide surfaces. Multiple silencing holes are provided on the sound-damping elements 122, and the multiple silencing holes are staggered to allow the gas to flow upwards in an S-shape within the through-type ventilation channel.
[0055] The working principle and technical effects of the above scheme are as follows:
[0056] In a fully enclosed sound barrier based on building energy-saving sound insulation material panels of the present invention, the ventilation and noise reduction structure 120 achieves efficient suppression of broadband noise by organically combining resistive and reactive noise reduction while ensuring ventilation and smoke exhaust functions. In the present invention, the sound-absorbing component 121, the sound-damping component 122, and the support plate 123 together form a through-type ventilation channel to achieve the ventilation function. The noisy gas enters from the normally open smoke exhaust port at the top of the portal steel frame structure 130, is forced through this channel, and is finally discharged by the sound-absorbing components 121 on both sides; multiple sound-damping components 122 are staggered on the lower surface of the support plate 123 and the upper surface of the smoke exhaust port, forming an acoustically abrupt interface. When sound waves propagate within the channel, they undergo multiple reflections and interferences at these interfaces due to sudden changes in the cross-sectional area (i.e., impedance mismatch), thus consuming sound energy. The staggered sound-absorbing elements 122 and their first air guide surfaces, along with the staggered silencing holes on the sound-absorbing elements 122, collectively guide the gas to flow in an S-shape within the channel. This not only prolongs the propagation path and time of noise within the ventilation and noise reduction structure 120 but also forces the sound waves to undergo more reflections, diffractions, and collisions, further exacerbating the attenuation of sound energy. Sound absorption... Component 121 is designed as a louver structure, with the second air guiding surface on its multiple blades forming an angle with the first air guiding surface, which not only helps to guide the airflow, but also guides the sound waves to the surface of the sound-absorbing material. The building energy-saving sound insulation material board 110, sound-absorbing component 121, sound-damping component 122 and support plate 123 all use porous sound-absorbing materials such as aluminum honeycomb perforated sound-absorbing board, flame-retardant foam aluminum sound-absorbing board or mineral wool sound-absorbing board. When the sound waves enter the micropores of these materials, the sound energy will be converted into heat energy due to air friction and viscous resistance, and thus be efficiently absorbed.
[0057] The ventilation and noise reduction structure 120 of this invention innovatively integrates two classic principles—resistive noise reduction (handling low and mid-frequency noise through the abrupt interface and S-shaped path formed by the sound-absorbing component 122) and resistive noise reduction (handling mid and high frequencies through the porous materials of components such as the sound-absorbing component 121)—into a compact ventilation duct. This composite design overcomes the frequency band limitations of single noise reduction technologies, achieving full-band, efficient control of broadband noise generated by rail transit and significantly improving the overall insertion loss value of the fully enclosed sound barrier. This invention successfully solves the core contradiction that fully enclosed sound barriers must have smoke exhaust vents, and that openings inevitably lead to "sound leakage." Physically, it forms an "acoustic filter" that allows air to pass smoothly but effectively blocks noise propagation, fundamentally compensating for the key shortcoming of noise leakage at the smoke exhaust vent.
[0058] Example 6: As Figures 1-14As shown, the bottom of the lifting drive plate 4 is fixedly connected to the upper end of the rectangular vertical rod 7. The middle part of the rectangular vertical rod 7 is slidably fitted in the rectangular longitudinal hole of the assembly frame plate 141. The lower end of the rectangular vertical rod 7 is fixedly connected to the spring seat 8. The spring seat 8 and the assembly frame plate 141 are connected by a tension spring 9 sleeved on the rectangular vertical rod 7. The upper surface of the assembly frame plate 141 is fixedly connected to the fixed support 10. The fixed support 10 is slidably connected to the guide slide shaft 11. The two ends of the guide slide shaft 11 are fixedly connected to the top pressure plate 12 and the limiting block, respectively. The top pressure plate 12 and the fixed support 10 are connected by a reset compression spring 13 sleeved on the guide slide shaft 11. The top pressure plug 14 fixed on the top pressure plate 12 is inserted into the limiting plug on the side of the rectangular vertical rod 7. The lower inner side of the top pressure plate 12 A pressure-bearing inclined surface 15 is provided; the upper end of the drive shaft 3 is fixedly connected to a first limiting cone ring 16 and a second limiting cone ring 17, the distance between the first limiting cone ring 16 and the second limiting cone ring 17 is greater than the height of the lifting drive plate 4, and the upper end of the drive shaft 3 is slidably fitted in the longitudinal through hole of the lifting drive plate 4; the first limiting cone ring 16 abuts against the upper surface of the lifting drive plate 4, and the second limiting cone ring 17 abuts against the upper surface of the assembly frame plate 141; the top-pressing inclined surface of the second limiting cone ring 17 is slidably fitted with the pressure-bearing inclined surface 15 of the top pressure plate 12, and when the drive shaft 3 drives the second limiting cone ring 17 to move upward until the second limiting cone ring 17 contacts the lower surface of the lifting drive plate 4, the top-pressing inclined surface of the second limiting cone ring 17 separates from the pressure-bearing inclined surface 15 of the top pressure plate 12.
[0059] The working principle and technical effects of the above scheme are as follows:
[0060] In normal operation, the top pressure block 14 fixed on the top pressure plate 12 is inserted into the limiting slot on the side of the rectangular vertical rod 7. This structural design effectively prevents the tension spring 9, which is in a stretched state between the spring seat 8 and the assembly frame plate 141, from resetting. The stretched state of the tension spring 9 is maintained, thus fixing the position of the lifting drive plate 4 connected to the top of the rectangular vertical rod 7. This ensures that the normally closed cover plate 143 can effectively seal the longitudinal smoke outlet 142. The stable sealing structure ensures the sound insulation and energy-saving performance of the fully enclosed sound barrier during normal use, and also prevents outside air from entering the sound barrier at will. The middle part of the rectangular vertical rod 7 slides within the rectangular longitudinal hole of the assembly frame plate 141, providing stable guidance for the movement of the lifting drive plate 4. Meanwhile, the upper end of the drive shaft 3 slides within the longitudinal through hole of the lifting drive plate 4, and the first limiting cone ring 16 abuts against the upper surface of the lifting drive plate 4, while the second limiting cone ring 17 abuts against the upper surface of the assembly frame plate 141. These structures work together to ensure that the positions of each component of the entire system are accurate and the connections are tight under normal conditions, further enhancing the stability of the normally closed cover plate 143 in sealing the longitudinal smoke outlet 142.
[0061] When a fire occurs, the pressure in the heated zone of the heating cylinder 1 increases, pushing the piston disc 2 upward. This causes the drive shaft 3 to move the second limiting cone ring 17 upward. Because the distance between the first limiting cone ring 16 and the second limiting cone ring 17 is greater than the height of the lifting drive plate 4, the drive shaft 3 first moves the second limiting cone ring 17 upward a certain distance. This design divides the system's opening process into two steps: first, the restriction on the return of the tension spring 9 is released, and then the lifting drive plate 4 is pushed upward. This avoids the significant resistance and potential jamming caused by direct pushing, improving the reliability of the system's operation. When the top-pressing inclined surface and the bearing inclined surface cooperate, and the second limiting cone ring 17 moves upward, its top-pressing inclined surface pushes the bearing inclined surface 15 of the top-pressing plate 12 to move outward. By using the inclined surface cooperation, the longitudinal movement of the drive shaft 3 is converted into the lateral movement of the top-pressing plate 12, which cleverly realizes the function of the top-pressing insert 14 disengaging from the side limiting insertion port of the rectangular vertical rod 7. Through the sliding cooperation of the inclined surfaces, a large lateral component force can be generated under a small longitudinal force, so that the top-pressing plate 12 can smoothly compress the reset spring 13 and drive the top-pressing insert 14 to disengage from the limiting insertion port, creating conditions for the reset of the tension spring 9; when the drive shaft 3 drives the second limiting cone ring 17 When the lifting drive plate 4 moves upward and contacts its lower surface, the top pressure slope of the second limiting cone ring 17 separates from the bearing slope 15 of the top pressure plate 12. At this time, on the one hand, the drive shaft 3 and the second limiting cone ring 17 continue to push the lifting drive plate 4 upward; on the other hand, the spring seat 8 at the lower end of the rectangular vertical rod 7 moves towards the assembly frame plate 141 under the elastic force of the tension spring 9, causing the top of the rectangular vertical rod 7 to drive the lifting drive plate 4 upward. This dual-drive method greatly accelerates the rising speed of the lifting drive plate 4, so that the normally closed cover plate 143 can quickly release the seal on the longitudinal smoke outlet 142 and promptly discharge the smoke generated by the fire. For example, in the event of a fire, quickly opening the longitudinal smoke outlet can effectively reduce the smoke concentration inside the sound barrier, buying valuable time for personnel evacuation and rescue work.
[0062] In this invention, the first limiting cone ring 16 and the second limiting cone ring 17 not only restrict the position of the lifting drive plate 4 and the assembly frame plate 141, but also ensure the accurate relative position of each component during system movement. During the rising and falling of the drive shaft 3, the cooperation of the first limiting cone ring 16 and the second limiting cone ring 17 prevents the lifting drive plate 4 from rising or falling excessively, avoiding damage due to component collisions or improper positioning, and further extending the service life of the system. Through ingenious structural design, this invention ensures the stable closure of the normally closed cover plate 143 to the longitudinal smoke outlet 142 under normal conditions, and achieves automatic and rapid opening in a fire, while simultaneously improving the reliability and durability of the system, demonstrating significant technical effects and practical application value.
