Description

Technical Field

[0001] The invention relates to the technical field of railway passenger stations, in particular to a clamshell type vibration and noise reduction structure used in large railway passenger stations. Background Art

[0002] With the continuous development of modern transportation, the construction of large-scale railway passenger stations is increasing. However, the dense crowds, frequent vehicle traffic and the operation of various equipment in the passenger stations cause a lot of noise and vibration in the stations. These noise and vibrations will not only affect the passengers' riding experience and make the station environment noisy and uncomfortable, but long-term exposure to such an environment may also have an adverse effect on the service life of the facilities and equipment in the station.

[0003] When faced with these problems, traditional building structures often lack effective means of vibration and noise reduction, and it is difficult to meet the needs of large railway passenger stations for a comfortable and quiet environment. For example, it is difficult to fully cope with complex sound wave propagation and vibration transmission by relying solely on simple sound insulation materials, and the dust adsorbed on the surface of the sound insulation material will affect the overall sound insulation and vibration reduction effect. The sound insulation material located on the top of the station has many inconveniences in daily maintenance, especially in dust cleaning, which is inconvenient to operate. At the same time, as a place with a large number of people, the hot air exhaled by people and the steam generated by their own heat will naturally rise upwards and then gather in the top area of ​​the station. Although the station is equipped with a ventilation system, this type of ventilation system is usually mostly located in the middle position.

[0016] Beneficial Effects

[0017] The present invention provides a clamshell type vibration and noise reduction structure for large railway passenger stations. Compared with the prior art, it has the following beneficial effects:

[0018] 1. The clamshell-type vibration-damping and noise-reducing structure used in large railway passenger stations has a protective layer as the first line of defense for vibration buffering. It can initially absorb and reflect high-frequency, low-amplitude tiny vibrations through its own elastic deformation. The internal rubber vibration isolation pad can buffer and isolate medium and low-frequency vibrations, and consume vibration energy through the elastic strain of the rubber molecular chain. When vibration occurs, the second shock absorber can rely on the spring to provide elastic support and deformation buffering, and the damping element consumes vibration energy, suppresses the free vibration of the spring, and reduces the vibration transmission rate. The air spring layer relies on the variable stiffness characteristics to adaptively adjust the stiffness according to the vibration conditions and adapt to complex and changeable vibrations. The combination of various structures can effectively disperse the vibration energy, block the vibration propagation of sound waves, and achieve good vibration-damping and noise-reduction effects.

[0019] 2. The clamshell-type vibration and noise reduction structure used in large railway passenger stations, the sound-absorbing panel in the auxiliary component can absorb the vibration sound waves that are still transmitted downward after vibration reduction, and due to its mobility, it can convert high-frequency and low-amplitude vibrations into large-amplitude and low-frequency vibrations, effectively reducing the sound generated by the sound-absorbing panel after receiving the sound waves, and further blocking the reflection of sound waves. At the same time, the vibration of the sound-absorbing panel can be transmitted through structures such as connecting rods and moving rods, absorbed by the spring, and then buffered by the compression and release of the air through the piston plate, ensuring that the sound waves and vibrations will not be transmitted downward in large quantities, further improving the overall noise reduction effect.

[0020] 3. The clamshell-type vibration-damping and noise-reducing structure used in large railway passenger stations has a cleaning component that can use the piston plate to move up and down to inhale and exhaust air, allowing the air to enter the storage box for storage, and monitor the air pressure in the storage box through an air pressure sensor. When the air pressure reaches a certain level, the pressure relief valve is activated to blow the compressed air in the storage box out through a wind knife to clean the dust attached to the bottom of the building roof. In this way, the building roof can be cleaned every once in a while, reducing the impact of dust attachment on the sound absorption and vibration reduction effect of the building roof, ensuring that the vibration-damping and noise reduction functions can function stably and for a long time, and reducing maintenance costs.

[0021] 4. The clamshell-type vibration-damping and noise-reducing structure used in large railway passenger stations can clean and store the steam accumulated on the top during the gas absorption process. The gas containing a certain amount of moisture can better combine with it when cleaning the dust, thereby improving the cleaning effect. At the same time, it ensures that the mass of the dust and moisture increases after combining and can float downward to avoid accumulation on the top of the station again, thereby reducing the influence of the attached dust on the sound absorption and vibration reduction effect of the building roof, and continuously ensuring the effective performance of the sound absorption and vibration reduction function.

[0033] The present application is further described in detail below through drawings and examples.

[0034] Reference Figures 1 to 8The embodiment of the present application provides a clamshell-type vibration reduction and noise reduction structure for a large railway passenger station, including a main body block 1 and a main body support column 6, a frame 5 is fixedly installed on the outer side of the main body block 1, a vibration reduction and noise reduction component 2 is arranged between the frames 5, a cleaning component 4 is arranged at the bottom of the main body block 1, and an auxiliary component 3 is arranged at the bottom of the cleaning component 4, the vibration reduction and noise reduction component 2 includes a building roof 21 and an external support column 22, the building roof 21 is fixedly installed on the outer side of the main body block 1 and is located between adjacent frames 5, the building roof 21 includes a protective layer 211, the protective layer 211 is an arc-shaped clamshell, a rubber vibration isolation pad 212 and an air spring layer 213 are fixedly installed inside the protective layer 211, the rubber vibration isolation pad 212 is located on the inner wall of the protective layer 211 near the bottom, the air spring layer 213 is located on the inner wall of the protective layer 211 near the top, and a second vibration absorber 214 is fixedly installed between the rubber vibration isolation pad 212 and the air spring layer 213. The protective layer 211 is made of a high-strength, corrosion-resistant metal alloy material, and is shaped like a clam shell with good sealing performance. The rubber vibration isolation pad 212 is made of a highly elastic, fatigue-resistant rubber material. The air spring layer 213 uses a sealed rubber airbag as an air spring, which is filled with gas. The second shock absorber 214 is composed of a plurality of independent spring and damping assembly components, which are evenly distributed between the rubber vibration isolation pad 212 and the air spring layer 213. A top plate 23 is fixedly installed on the top of the external support column 22, a connecting block 24 is fixedly installed on the top of the top plate 23, a bottom block 25 is fixedly installed on the bottom of the outer end of the skeleton 5, a first shock absorber 26 is fixedly installed between the connecting block 24 and the bottom block 25, and the main support column 6 and the external support column 22 are both fixedly installed on the ground.

[0035] In this embodiment, the skeleton 5 and the building roof 21 constitute the roof of the entire passenger station hall, and the overall roof is supported by the main support column 6 and the external support column 22. When the sound waves inside the hall are transmitted to the top of the roof, the vibration generated by the roof can be absorbed and buffered by the first vibration absorber 26. The first vibration absorber 26 can reduce part of the vibration generated by the roof, and the vibration propagation of the sound wave is blocked by reducing the vibration. When the sound wave is transmitted to the roof, the sound wave is further processed by the building roof 21, as follows: the protective layer 211 is used as the first vibration buffering line of defense, and some high-frequency, low-amplitude tiny vibrations are preliminarily absorbed and reflected through its own elastic deformation to prevent them from being directly transmitted to the internal structure. The internal rubber vibration isolation pad 212 can preliminarily buffer and isolate medium and low frequency vibrations. The elastic strain of the sub-chain during the compression and recovery process converts part of the vibration energy into heat energy and consumes it. When vibration occurs, the spring is responsible for providing elastic support and deformation buffering through the second shock absorber 214. The damping element plays a role at the same time, consuming vibration energy, suppressing the free vibration of the spring, and effectively reducing the vibration transmission rate. The air spring layer 213 has variable stiffness characteristics. According to the changes in vibration amplitude and frequency, the compression and relaxation of the internal gas can adaptively adjust the stiffness, and it has excellent adaptability to complex and changeable vibration conditions. Through the above-mentioned vibration reduction scheme and the clamshell-shaped protective layer 211, part of the vibration energy can be dispersed, so that the vibration will not be concentrated and transmitted to a certain place, but the energy is dispersed and buffered through the overall structure of the protective layer 211, thereby realizing the absorption and buffering of vibration, thereby realizing the vibration reduction and noise reduction function.

[0036] Reference Figures 1 to 8 In one aspect of the present embodiment, the auxiliary component 3 includes a sound absorbing panel 31, which is hinged on the outer side of the main support column 6, and a gas cylinder 34 is fixedly installed on the outer side of the main support column 6. A piston plate 35 is slidably connected inside the gas cylinder 34, and a moving rod 33 is fixedly installed on the top of the piston plate 35. A connecting rod 32 is hinged between the top of the moving rod 33 and the corresponding sound absorbing panel 31, and a baffle 8 is fixedly installed on the outer side of the main support column 6, and the baffle 8 is located below the gas cylinder 34.

[0037] A spring 36 is fixedly installed between the bottom of the piston plate 35 and the inner bottom of the gas cylinder 34, a connecting pipe 39 is fixedly installed at the bottom of the gas cylinder 34, a second one-way valve 38 is fixedly installed at the connection point between the connecting pipe 39 and the gas cylinder 34, and a first one-way valve 37 is fixedly installed inside the piston plate 35. The second one-way valve 38 is connected in a direction from the inside of the gas cylinder 34 to the inside of the connecting pipe 39, and the first one-way valve 37 is connected in a direction from the outside to the inside of the gas cylinder 34.

[0038] In this embodiment, after the vibration reduction is completed by the vibration reduction and noise reduction component 2, a part of the vibration sound waves will be transmitted downward. At this time, the sound wave vibration is absorbed by the sound absorbing plate 31 arranged below, and during absorption, due to the mobility of the sound absorbing plate 31, the vibration transmitted to the sound absorbing plate 31 will not generate high-frequency and low-amplitude vibrations with the sound waves, but will be converted into large-amplitude and low-frequency vibrations, thereby effectively reducing the sound generated by the sound absorbing plate 31 after receiving the sound waves, and further achieving the goal of blocking the reflection of the sound waves, and the up and down vibrations generated by the sound absorbing plate 31 will be transmitted to the connecting rod 32 below, and the connecting rod 32 can drive the moving rod 33 and the piston plate 35 to move downward, and the generated vibrations can be absorbed by the internal spring 36. After absorption, the piston plate 35 can compress and release air up and down to buffer the vibration absorbed by the spring 36, thereby achieving the goal of absorbing sound waves while reducing the vibrations generated by the sound absorbing plate 31 as a whole, thereby further reducing the downward transmission of sound waves and vibrations.

[0039] Reference Figures 1 to 8 In one aspect of the present embodiment, the cleaning assembly 4 includes a storage box 41, which is fixedly mounted on the bottom of the main block 1, and the main support column 6 is fixedly mounted on the bottom of the storage box 41. An internal groove 7 is opened inside the main support column 6, and a connecting pipe 39 passes through the interior of the internal groove 7. The outer end face of the connecting pipe 39 is fixedly mounted on the bottom of the storage box 41.

[0040] A third one-way valve 310 is fixedly installed at the connection point between the connecting pipe 39 and the storage box 41, and the connection direction of the third one-way valve 310 is from the inside of the connecting pipe 39 to the inside of the storage box 41. An air outlet pipe 42 is fixedly installed on the outside of the storage box 41, a connecting block 44 is fixedly installed on the outside of the air outlet pipe 42, and an air knife 45 is fixedly installed on the outside of the connecting block 44. The air knife 45 is connected to the inside of the air outlet pipe 42 through the connecting block 44, and the air knife 45 is located below the corresponding building top plate 21. A pressure relief valve 43 is fixedly installed at the connection point between the air outlet pipe 42 and the storage box 41, and an air pressure sensor is fixedly installed inside the storage box 41. The air pressure sensor is electrically connected to the pressure relief valve 43 through a controller.

[0041] In this embodiment, when the piston plate 35 moves up and down, air can be sucked in from the outside through the first one-way valve 37 and discharged into the connecting pipe 39 through the second one-way valve 38. The air enters the storage box 41 through the connecting pipe 39 for storage. The air pressure inside the storage box 41 gradually increases as the air gradually enters the storage box 41, and the third one-way valve 310 is used to ensure that the internal air does not flow back. The internal pressure is detected by the air pressure sensor inside the storage box 41. When the pressure reaches a certain level, the pressure relief valve 43 is activated by the controller, and the air outlet pipe 43 is activated. 42 is connected with the storage box 41. After the connection, the internal compressed air enters the wind knife 45 through the air outlet pipe 42, and is blown out through the wind knife 45 and blown to the bottom of the building roof 21. The high-pressure gas blown out by the wind knife 45 cleans the dust attached to the bottom of the building roof 21. The storage box 41 releases air once every period of time, so that the building roof 21 can be cleaned once every period of time. By cleaning the bottom of the building roof 21, the influence of the attached dust on the sound absorption and vibration reduction effect of the building roof 21 is reduced, and the sound absorption and vibration reduction effect is further ensured.

[0042] During the whole working process, the gas absorption operation is realized by means of the up and down movement of the piston plate 35. When the piston plate 35 moves upward, the steam accumulated on the top will be smoothly sucked into the interior of the gas cylinder 34 through the first one-way valve 37 connected thereto under the action of the pressure difference (at the same time, as a place with dense personnel, the hot air exhaled by people and the steam generated by the heat emitted by themselves will naturally rise upward and then gather in the top area of ​​the station. Although the station is equipped with a ventilation system, such ventilation systems are usually mostly arranged in the middle, making it difficult to effectively discharge the steam on the top of the station, and it is easy to accumulate on the top of the station). Then, as the first piston plate 35 moves downward, the gas in the gas cylinder 34 will be transported to the interior of the storage box 41 for storage under the pressure, which can effectively store and clean the steam accumulated on the top to avoid its adverse effects caused by long-term accumulation;

[0043] Moreover, at regular intervals, when the wind knife 45 is used to clean the dust on the building roof 21, since the gas involved in the cleaning contains a certain amount of moisture, this characteristic enables the gas to better combine with the dust. After the two are fully combined, not only the cleaning effect of the dust on the building roof 21 is significantly improved, but also during the cleaning process, the dust will merge with the moisture inside the gas, causing its overall mass to increase. After being sprayed out, the dust and moisture mixture with increased mass can float downward due to gravity, thereby effectively preventing them from accumulating on the top of the station again, thereby ensuring the cleanliness of the environment on the top of the station.

[0044] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] Working principle: the skeleton 5 and the building roof 21 form the roof of the entire passenger station hall, and the main support column 6 and the external support column 22 support the entire roof. When the sound waves inside the hall are transmitted to the top of the roof, the vibration generated by the roof can be absorbed and buffered by the first vibration absorber 26. The first vibration absorber 26 can reduce part of the vibration generated by the roof, and the vibration propagation of the sound wave can be blocked by reducing the vibration. When the sound wave is transmitted to the roof, the sound wave is further processed by the building roof 21, as follows: the protective layer 211 is used as the first vibration buffering line of defense, and some high-frequency, low-amplitude tiny vibrations are preliminarily absorbed and reflected through its own elastic deformation to prevent them from being directly transmitted to the internal structure. The internal rubber vibration isolation pad 212 can preliminarily buffer and isolate medium and low-frequency vibrations, and the rubber molecules The elastic strain of the chain during the compression and recovery process converts part of the vibration energy into heat energy and consumes it. When vibration occurs, the spring is responsible for providing elastic support and deformation buffering through the second shock absorber 214. The damping element plays a role at the same time, consuming vibration energy, suppressing the free vibration of the spring, and effectively reducing the vibration transmission rate. The air spring layer 213 has variable stiffness characteristics. According to the changes in vibration amplitude and frequency, the compression and relaxation of the internal gas can adaptively adjust the stiffness, and it has excellent adaptability to complex and changeable vibration conditions. Through the above-mentioned vibration reduction scheme and the clamshell-shaped protective layer 211, part of the vibration energy can be dispersed, so that the vibration will not be concentrated and transmitted to a certain place, but the energy is dispersed and buffered through the overall structure of the protective layer 211, thereby realizing the absorption and buffering of vibration, thereby realizing the vibration reduction and noise reduction function;

[0046] After the vibration reduction is completed by the vibration reduction and noise reduction component 2, a part of the vibration sound waves will be transmitted downward. At this time, the sound wave vibration is absorbed by the sound absorbing plate 31 arranged below. During the absorption, due to the mobility of the sound absorbing plate 31, the vibration transmitted to the sound absorbing plate 31 will not generate high-frequency and low-amplitude vibrations along with the sound waves, but will be converted into large-amplitude and low-frequency vibrations, thereby effectively reducing the sound generated by the sound absorbing plate 31 after receiving the sound waves, further achieving the goal of blocking the reflection of the sound waves, and the up and down vibrations generated by the sound absorbing plate 31 will be transmitted to the connecting rod 32 below, and the connecting rod 32 can drive the moving rod 33 and the piston plate 35 to move downward, and the internal spring 36 can absorb the generated vibrations. After absorption, the piston plate 35 can compress and release air up and down to buffer the vibrations absorbed by the spring 36, thereby achieving the goal of absorbing sound waves while reducing the vibrations generated by the sound absorbing plate 31 as a whole, thereby further reducing the downward transmission of sound waves and vibrations;

[0047] When the piston plate 35 moves up and down, air can be sucked in from the outside through the first one-way valve 37 and discharged into the connecting pipe 39 through the second one-way valve 38. The air enters the storage box 41 through the connecting pipe 39 for storage. The air pressure inside the storage box 41 gradually increases as the air gradually enters. The third one-way valve 310 ensures that the internal air does not flow back. The internal pressure is detected by the air pressure sensor inside the storage box 41. When the pressure reaches a certain level, the pressure relief valve 43 is activated by the controller. After activation, the air outlet pipe 42 and The storage box 41 is connected, and after the connection, the internal compressed air enters the air knife 45 through the air outlet pipe 42, and is blown out through the air knife 45 and blown to the bottom of the building roof 21. The high-pressure gas blown out by the air knife 45 cleans the dust attached to the bottom of the building roof 21. The storage box 41 releases air once every period of time, so that the building roof 21 can be cleaned once every period of time. By cleaning the bottom of the building roof 21, the influence of the attached dust on the sound absorption and vibration reduction effect of the building roof 21 is reduced, and the sound absorption and vibration reduction effect is further ensured;

[0048] During the whole working process, the gas absorption operation is realized by means of the up and down movement of the piston plate 35. When the piston plate 35 moves upward, the steam accumulated on the top is smoothly sucked into the inside of the gas cylinder 34 through the first one-way valve 37 connected thereto under the action of the pressure difference. Then, as the first piston plate 35 moves downward, the gas in the gas cylinder 34 is transported to the inside of the storage box 41 for storage under the pressure, which can effectively store and clean the steam accumulated on the top to avoid its long-term accumulation and cause adverse effects.

[0049] Moreover, at regular intervals, when the wind knife 45 is used to clean the dust on the building roof 21, since the gas involved in the cleaning contains a certain amount of moisture, this characteristic enables the gas to better combine with the dust. After the two are fully combined, not only the cleaning effect of the dust on the building roof 21 is significantly improved, but also during the cleaning process, the dust will merge with the moisture inside the gas, causing its overall mass to increase. After being sprayed out, the dust and moisture mixture with increased mass can float downward due to gravity, thereby effectively preventing them from accumulating on the top of the station again, thereby ensuring the cleanliness of the environment on the top of the station.
