Description

Technical Field

[0001] The invention relates to the technical field of green buildings, and in particular to an energy-saving and noise-reducing wall structure of a green building. Background Art

[0002] The hazards of noise pollution include interference with people's rest, study and work, as well as adverse effects on people's hearing, vision, nervous system, etc. Long-term exposure to noise pollution may cause eye damage such as eye fatigue, eye pain, blurred vision and tearing, and may also lead to disorders of excitement and inhibition of the cerebral cortex, resulting in symptoms such as dizziness, headache, tinnitus, and in severe cases, mental disorder. In addition, noise can accelerate heart aging and increase the incidence of myocardial infarction.

[0003] Noise pollution at construction sites is a common problem that can have a negative impact on the health and lives of nearby residents. On construction sites, noise usually comes from mechanical equipment, such as excavators, steel shears, and concrete mixers. Manual operations can also cause a certain degree of noise pollution. In order to reduce noise pollution at construction sites, the following measures are generally taken: choose mechanical equipment with low noise, or soundproof the mechanical equipment when necessary; set up sound barriers around the construction site to reduce the spread of noise; inform residents around the construction site before construction, inform them of the construction time and noise conditions, and try to reduce construction noise at night or on weekends; reasonably design the layout of the construction site, properly arrange the time and location of the use of mechanical equipment, and avoid using multiple noisy mechanical equipment at the same time. Noise at construction sites is usually transmitted through vibration. The noise source that generates vibration (such as mechanical equipment, tools, etc.) will cause the surrounding solid structures to vibrate, and then transmit the vibration to the building and the surrounding environment, thereby generating noise.

[0004] In response to the problem of vibration-transmitted noise at construction sites, the existing technology can reduce the spread of noise vibration and reduce the impact on the surrounding environment by setting up sound barriers and sound insulation facilities around the construction site to affect the propagation path and attenuation of noise vibration. However, the interior of the existing sound insulation walls is mostly filled with fixed sound-absorbing and sound-insulating materials. Due to the vibration of the construction site, the structure inside the wall generates vibration noise that propagates across the wall, so a large amount of shock-absorbing and sound-absorbing materials are required to achieve a good noise reduction effect. In addition, when sound waves enter the sound-absorbing material, they are absorbed by the micropores and fibers in the material. When the sound-absorbing material remains in a state for a long time, the micropore structure and fiber material of the sound-absorbing material may be gradually blocked or destroyed over time, resulting in a decrease in its sound absorption performance. Its physical properties and acoustic properties may be affected, making the sound absorption effect worse, resulting in increased construction costs, building costs and maintenance costs.

[0005] The present invention designs a green building energy-saving and noise-reducing wall structure to solve the above-mentioned technical problems. Summary of the invention

[0006] The technical purpose to be achieved by the present invention is: when the construction site transmits noise due to the vibration of the construction ground, the setting of the noise reduction wall can change the distribution of the sound-absorbing material inside the wall according to the amplitude and time of the vibration, thereby affecting the propagation path and attenuation degree of the noise vibration, so that the noise is absorbed layer by layer inside the noise reduction wall, and the internal structure of the noise reduction wall is distributed at intervals to interrupt the sound wave transmission sound bridge inside the noise reduction wall, thereby reducing the propagation of noise across the wall.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0008] A green building energy-saving and noise-reducing wall structure comprises an original wall and an outer wall, wherein the original wall is arranged at a construction site, and the outer wall is arranged at one side of the original wall, and further comprises a vibration-starting mechanism and a noise-reduction mechanism, wherein the vibration-starting mechanism is installed inside the original wall, and the noise-reduction mechanism is installed above the vibration-starting mechanism, and the vibration-transmitting rack in the vibration-starting mechanism moves upward under the vibration of the ground, driving the half-tooth gear of the meshing auxiliary gear on one side to rotate while the full-tooth gear rotates, the center rotating block is driven to rotate by the full-tooth gear of the auxiliary gear, and the full-tooth gear on the other side is driven to rotate by the center rotating block so that the gear surface of the half-tooth gear meshes with the vibration-transmitting rack, the embedded ratchet in the center rotating block rotates, and the linkage gear of the linkage rotating block rotates through the coordinated rotation of the ratchet pawl, the transmission rack is driven to move upward by the linkage gear while driving the push block to move upward, and the contraction blocks distributed in a linear array are limited from sparse to At the same time, the sound-absorbing blocks are densely distributed with equal spacing on both sides, and the sound-absorbing blocks are densely distributed in the middle, so that the sound-absorbing blocks with dense spacing on both sides and in the middle will be transformed into dense distribution in the middle of the gaps on both sides when the vibration noise is too large. The sound-absorbing blocks with gaps on both sides can absorb the noise generated by the vibration, and the sound-absorbing blocks with dense distribution in the middle absorb the noise layer by layer, thereby effectively absorbing the incoming noise and reducing the propagation of noise in the noise reduction wall. The rear spring is continuously energy stored by the rotation of the linked gear. Under the unidirectional transmission action of the ratchet pawl, the rear spring makes the linked gear rotate in the opposite direction and drives the transmission rack to move downward, and the contraction blocks restore the original spacing from dense to sparse, and the sound-absorbing blocks are densely distributed in the middle on both sides. In the original state, the sound-absorbing blocks are densely distributed on both sides of the noise reduction wall, and are spaced inside the noise reduction wall, so that the noise is concentratedly attenuated on the outermost part and filtered and attenuated layer by layer after passing through the densely distributed sound-absorbing cotton on the outside.

[0009] The vibration-starting mechanism includes a vibration-transmitting rack, an auxiliary gear, a center rotating block, a linkage rotating block and a transmission rack; the vibration-transmitting rack is arranged inside the outer wall, and the upper and lower ends of the vibration-transmitting rack are symmetrical truncated cones. The truncated cone structure is relatively stable and has good load-bearing capacity and pressure resistance. It can provide better support when the vibration-transmitting rack is transmitted up and down. Compared with structures of some other shapes, the truncated cone shape is more able to maintain balance and stability, and reduce the possibility of abnormal movement and shaking. When the truncated cone shape is transmitted up and down, its own weight can be evenly distributed through the structure, which is beneficial for maintaining stability and reducing the pressure of load concentrated on a single point, and is helpful for deformation and damage caused by uneven stress distribution of the vibration-transmitting rack during vibration. When the truncated cone structure is transmitted up and down, the lower height can increase the overall rigidity of the structure compared to the larger bottom, and can reduce the deformation and vibration of the vibration-transmitting rack structure. The left and right sides of the vibration transmission rack are symmetrically distributed racks. The symmetrical racks make the vibration transmission rack moving up and down evenly disperse the stress from both sides, thereby enhancing the stability of the vibration start mechanism. The auxiliary gears are symmetrically installed on both sides of the vibration transmission rack, one end of the central rotating block is installed at the symmetry axis position of the two auxiliary gears, and the linkage rotating block is vertically installed at the other end of the central rotating block. By symmetrically installing the auxiliary gears on both sides of the vibration transmission rack and vertically installing the linkage rotating block at the other end of the central rotating block, the vibration start mechanism can be subjected to more balanced force during operation, thereby reducing the wear and fatigue of system components. The transmission rack is installed on the side of the linkage rotating block.

[0010] The auxiliary gear has a "double-layer tooth" structure, and the double-layer teeth are coaxially fixedly connected. The layer of gear that meshes with the auxiliary gear and the vibration transmission rack is a half-tooth gear. The half-tooth gear has a certain smooth surface due to the small number of teeth. When one end of the vibration transmission rack meshes with the half-tooth gear, the other end of the vibration transmission rack moves parallel to the smooth surface of the half-tooth gear, so that when the vibration transmission rack reciprocates up and down, the transmission of the half-tooth gears on the left and right sides does not interfere with each other, and the layer that meshes with the driving gear and the center rotating block is a full-tooth gear.

[0011] The center rotating block includes a center gear, a center rotating shaft and an embedded ratchet. The center gear is installed at one end of the center rotating block, one end of the center rotating shaft is fixedly installed at the center axis position of the center gear, and the embedded ratchet is fixedly installed at the other end of the center rotating shaft. The center gear and the embedded ratchet are parallel to each other and rotate coaxially. Since the two are on the same axis, the load distribution of the center rotating block is more uniform, and the transmission error is reduced, thereby improving the accuracy and stability of the center rotating block transmission.

[0012] The linkage rotating block includes a linkage gear, an embedded pawl and a rear spring. The linkage gear is installed at one end of the linkage rotating block. The embedded pawl is installed in a circular array inside the linkage gear with the central axis of the linkage gear as the center. During the transmission process, when the embedded ratchet rotates, the embedded pawl installed in the circular array engages with the embedded ratchet to transmit torque. Since the embedded pawl can only move in one direction, the pawl can only achieve one-way transmission. The pawls distributed in the circular array can provide better support and balance, thereby reducing the wear and deformation of the shock-starting mechanism. The center of the rear spring is fixedly installed at the central axis position of the linkage gear.

[0013] The upper end of the transmission rack is shaped like an isosceles trapezoid. The structural design of the isosceles trapezoid, which is narrow at the top and wide at the bottom, concentrates the force of the upward movement of the transmission rack on the upper end, and the inclined two sides make the transmission rack bear the load more evenly when transmitting up and down. The lower end of the transmission rack is connected to a tooth through a spring, so that after the transmission rack moves to the extreme position, the transmission rack and the linkage gear are elastically meshed.

[0014] The noise reduction mechanism includes a fixing frame, a shrinkage block, a pushing block and a sound-absorbing block. The fixing frame is installed inside the outer wall, one side of the shrinkage block is installed with a linear array on one side of the fixing frame, and the pushing block is installed on the other side of the shrinkage block. The shrinkage blocks are evenly spaced and distributed under the restriction of the pushing block. Stability: the shrinkage blocks installed in the linear array can enhance the stability of the internal structure of the wall, and the shrinkage blocks installed in the linear array can reduce the impact of external vibration interference on the inside of the wall. The stability of the bracket helps to reduce the interference of vibration and noise. The sound-absorbing blocks are installed at intervals between the fixing frame and the shrinking block. Common sound-absorbing materials include mineral wool sound-absorbing board: mineral wool sound-absorbing board is a common sound-absorbing material, which has the advantages of sound absorption, fire resistance, heat insulation, environmental protection, easy processing, etc., and is widely used in interior decoration; polyester fiber sound-absorbing board: polyester fiber sound-absorbing board is an ideal indoor sound insulation material. Its raw material is 100% polyester fiber, which has the advantages of sound absorption, flame retardancy, heat insulation, heat preservation, moisture resistance, mildew resistance, high cost performance, etc.; wooden sound-absorbing board: wooden sound-absorbing board is a high-efficiency sound-absorbing material, which has the advantages of high density, high sound absorption, environmental protection, etc., and is widely used in Concert halls, theaters and other places that require high-quality sound effects; soft-pack sound-absorbing panels: soft-pack sound-absorbing panels are a common sound-absorbing material, which has the advantages of sound absorption, flame retardancy, heat insulation, environmental protection, etc., and is widely used in interior decoration; diatom mud: diatom mud is a sound-absorbing material with the advantages of sound absorption, environmental protection, and easy processing, and is widely used in interior decoration; sound insulation felt: glass wool uses a kind of man-made inorganic fiber with a tight structure, high sound absorption rate, not easy to deform, and high cost performance. It is a common sound insulation material, which has the advantages of sound insulation, flame retardancy, and heat insulation. The sound-absorbing blocks installed at intervals can reduce the vibration connection between the fixed frame and the shrinkage block, thereby reducing the path of solid noise transmission.

[0015] The fixing frame is a bilaterally symmetrical structure. The bilaterally symmetrical design makes the fixing frame more balanced when subjected to force, reduces deformation and damage caused by eccentric load or asymmetry, improves the stability of the structure, and the symmetrical design can better maintain the accuracy. In the process of processing and manufacturing, the bilaterally symmetrical mechanism can reduce the error caused by stress concentration or asymmetry, thereby ensuring the accuracy and quality of the fixing frame. The bilaterally symmetrical fixing frame can better distribute the load, making the force more uniform, which helps to reduce the stress concentration and local fatigue inside the sound reduction wall, and improves the life and reliability of the fixing frame. The symmetrical design makes the fixing frame more convenient and quick when installed. Only by determining the position of the center line and the positioning hole, the fixing frame can be easily installed inside the outer wall. The thickness of the fixed keel at both ends of the fixing frame is greater than the fixed keel in the middle position. Since the sound-absorbing cotton and the fixed push block need to be installed at both ends of the fixing frame, the thickness of the fixed keel at both ends of the fixing block is greater than that in the middle position. The two ends of the fixing frame are symmetrically provided with push plate slides, and the middle position of the fixing frame is fixed with two parallel push rod slides.

[0016] The shrink block includes a moving keel and a sliding knob. One side of the moving keel is slidably mounted on one side of the fixing frame. The upper end of the moving keel is "beveled". The beveled design can reduce the contact area between the moving keel and the noise reduction wall, thereby reducing friction. Due to the reduction in contact area, the friction torque between each other will also be reduced accordingly. The beveled design can disperse the pressure on the contact surface to avoid excessive local pressure. In this way, the wear and deformation of the surface of the object can be reduced, thereby reducing the friction resistance. The beveled design can increase the fluidity of the lubricant between the contact surfaces, so that the lubricant is better distributed on the friction surface, thereby reducing the friction coefficient, achieving the purpose of reducing friction, thereby reducing the noise transmission inside the wall. The sliding knob is fixedly mounted at the lower position of the moving keel, so that when the push block is below the moving keel, the sliding knob is stable at the upper end of the shrinking slide rail with a larger gap. When the push plate rises, the sliding knob is at the lower end of the shrinking slide rail with a smaller gap, thereby realizing the equal spacing distribution of the moving keel from sparse to dense, and a sound absorbing block is still installed below the moving keel.

[0017] The pushing block includes a sliding push plate, a push plate slider, a retractable slide rail and a transmission push groove. The sliding push plate is slidably installed on one side of the retractable block, and the push plate slider is installed at both ends of one side of the sliding push plate. The retractable slide rail is opened on the sliding push plate, and the spacing of the retractable slide rail in the horizontal cross-sectional direction of the sliding push plate increases successively. The structure of the spacing increasing successively in the horizontal cross-sectional direction allows the retractable block to become sparse or densely distributed with equal spacing from the middle to both sides, and the spacing in the cross-sectional direction of the retractable slide rail is equal. The shape of the transmission push groove is an isosceles trapezoid that matches the transmission rack. Under the sliding cooperation of the two waists of the isosceles trapezoid, accidental contact or collision between the upper end of the transmission rack and the lower end of the pushing slide plate can be prevented.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention sets a vibration-starting mechanism and a noise reduction mechanism on the noise reduction wall. When vibration is generated during construction at the building site, the vibration-starting mechanism transmits the vibration to the noise reduction mechanism through a transmission rack, so that the sound-absorbing blocks densely distributed at both sides and spaced in the middle are transformed into densely distributed in the middle with gaps on both sides when the vibration noise is relatively large. The sound-absorbing blocks distributed in the gaps on both sides can absorb the noise generated by the vibration, and the sound-absorbing blocks densely distributed in the middle absorb the noise layer by layer, thereby effectively absorbing the incoming noise and reducing the propagation of noise in the noise reduction wall. The variable gap distribution of the sound-absorbing blocks can also reduce the reflection and propagation of noise and the blockage or damage of the microporous structure and the fiber material, thereby reducing the maintenance cost and improving the sound insulation and noise reduction effect of the noise reduction wall.

[0020] 2. The present invention arranges a vibration-transmitting rack of a vibration-starting mechanism to generate up and down reciprocating motion due to ground vibration. The central rotating block keeps rotating when the construction site continues to vibrate and generate noise, so that the transmission rack maintains stable transmission under vibration. The rear spring stores energy, and the transmission rack is reset when the vibration is severe and lasts for a long time, which saves energy while ensuring the stability of the noise reduction wall mechanism.

[0021] 3. The present invention provides a sliding push plate of the noise reduction mechanism so that when the linearly distributed moving keels are limited by the retracted slide rail and the ground continues to vibrate, the moving keels gather toward the middle and are evenly spaced, thereby increasing the distance between the moving keels and the fixed keels on both sides, thereby interrupting the solid-propagation sound bridge and reducing the noise propagation path.

DETAILED DESCRIPTION

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figures 1 to 14As shown, a green building energy-saving and noise-reducing wall structure includes an original wall 1 and an outer wall 2. The outer wall 2 can be installed on one side of the original wall at the construction site by pasting or manually. The outer layer of the outer wall 2 is sprayed with a sound insulation coating, such as relatively thin polyester fiber and sound insulation foam. These materials have high sound absorption performance and can effectively absorb and isolate noise. The original wall 1 is a wall of a construction site, and the outer wall 2 is arranged on one side of the original wall 1, and also includes a vibration-starting mechanism 3 and a noise reduction mechanism 4. The vibration-starting mechanism 3 is installed inside the outer wall 2, and the noise reduction mechanism 4 is installed above the vibration-starting mechanism 3. The vibration-transmitting rack 31 in the vibration-starting mechanism 3 moves upward under the vibration of the ground, driving the half-tooth gear 321 of the meshing auxiliary gear 32 on one side to rotate, and the full-tooth gear 322 rotates at the same time. The central rotating block 33 is driven to rotate by the full-tooth gear 322 of the auxiliary gear 32, and the full-tooth gear 322 on the other side is driven to rotate by the central rotating block 33 so that the gear surface of the half-tooth gear 321 meshes with the vibration-transmitting rack 31. The embedded ratchet 333 in the central rotating block 33 rotates, and the linkage gear 341 of the linkage rotating block 34 rotates through the coordinated rotation of the ratchet pawl. The transmission rack 35 is driven upward by the linkage gear 341 and drives the push block 43 to move upward at the same time. The contraction blocks 42 distributed in the linear array are limited from sparse to The sound absorbing blocks 44 are densely distributed with equal spacing on both sides and densely distributed in the middle, so that the sound absorbing blocks 44 with dense spacing on both sides and dense distribution in the middle will be transformed into the gaps on both sides and dense distribution in the middle when the vibration noise is too large. The sound absorbing blocks 44 with gaps on both sides can absorb the noise generated by the vibration, and the sound absorbing blocks 44 with dense distribution in the middle absorb the noise layer by layer, thereby effectively absorbing the incoming noise and reducing the propagation of the noise in the noise reduction wall. The rear spring 343 is continuously energy stored by the rotation of the linkage gear 341. Under the unidirectional transmission action of the ratchet pawl, the rear spring 343 makes the linkage gear 341 rotate in the opposite direction to drive the transmission rack 35 to move downward, and the contraction block 42 recovers the original spacing from dense to sparse. The sound absorbing blocks 44 are densely distributed on both sides and densely distributed in the middle. In the original state, the sound absorbing blocks 44 are densely distributed on both sides of the noise reduction wall and are spaced inside the noise reduction wall, so that the noise is concentratedly attenuated in the outermost part, and is filtered and attenuated layer by layer after passing through the densely distributed sound-absorbing cotton on the outside, thereby reducing the propagation of noise.

[0041] like Figure 3As shown, the vibration-starting mechanism 3 includes a vibration-transmitting rack 31, an auxiliary gear 32, a center rotating block 33, a linkage rotating block 34 and a transmission rack 35; the vibration-transmitting rack 31 is arranged in the outer wall 2, and the upper and lower ends of the vibration-transmitting rack 31 are symmetrical truncated cones. The truncated cone structure is relatively stable, has good bearing capacity and pressure resistance, and can provide better support when the vibration-transmitting rack 31 is transmitted up and down. Compared with structures of some other shapes, the truncated cone shape is more able to maintain balance and stability, and reduce the possibility of abnormal movement and shaking. When the truncated cone shape is transmitted up and down, its own weight can be evenly distributed through the structure, which is beneficial for maintaining stability and reducing the pressure of load concentrated on a single point, and is helpful for deformation and damage caused by uneven stress distribution of the vibration-transmitting rack 31 during vibration. When the truncated cone structure is transmitted up and down, the lower height can increase the overall rigidity of the structure compared to the larger bottom, and can reduce the deformation and vibration of the vibration-transmitting rack 31 structure. The left and right sides of the vibration transmission rack 31 are symmetrically distributed racks. The symmetrical racks enable the vibration transmission rack 31 that moves up and down to evenly disperse the stress on both sides, thereby enhancing the stability of the vibration start mechanism 3. The auxiliary gears 32 are symmetrically installed on both sides of the vibration transmission rack 31, one end of the center turn block 33 is installed at the symmetry axis position of the two auxiliary gears 32, and the linkage turn block 34 is vertically installed at the other end of the center turn block 33. By symmetrically installing the auxiliary gears 32 on both sides of the vibration transmission rack 31 and vertically installing the linkage turn block 34 at the other end of the center turn block 33, the vibration start mechanism 3 can be subjected to more balanced force during operation, thereby reducing the wear and fatigue of system components. The transmission rack 35 is installed on the side of the linkage turn block 34. The vibration start mechanism 3 can transmit vibration according to the degree and duration of vibration, thereby combining with the noise reduction mechanism 4 to achieve energy saving and noise reduction of the noise reduction wall.

[0042] like Figure 4 As shown, the auxiliary gear 32 is a "double-layer tooth" structure, and the double-layer teeth are coaxially fixedly connected. The layer of gears that meshes with the auxiliary gear 32 and the vibration transmission rack 31 is a half-tooth gear 321. The half-tooth gear 321 has a certain smooth surface due to the small number of teeth. When one end of the vibration transmission rack 31 meshes with the half-tooth gear 321, the other end of the vibration transmission rack 31 moves parallel to the smooth surface of the half-tooth gear 321, so that when the vibration transmission rack 31 reciprocates up and down, the transmission of the half-tooth gears 321 on the left and right sides does not interfere with each other, and the layer of the driving gear that meshes with the center rotating block 33 is a full-tooth gear 322. The design of the half-tooth gear 321 and the full-tooth gear 322 in the auxiliary gear 32 converts the vibration of the uncertain direction of the ground into continuous and stable rotation of the center gear 331, making the transmission of the vibration start mechanism 3 more stable.

[0043] like Figure 6As shown, the center rotating block 33 includes a center gear 331, a center rotating shaft 332 and an embedded ratchet 333. The center gear 331 is installed at one end of the center rotating block 33, one end of the center rotating shaft 332 is fixedly installed at the center axis position of the center gear 331, and the embedded ratchet 333 is fixedly installed at the other end of the center rotating shaft 332. The center gear 331 and the embedded ratchet 333 are parallel to each other and rotate coaxially. Since the two are on the same axis, the load distribution of the center rotating block 33 is more uniform, and the transmission error is reduced, thereby improving the transmission accuracy and stability of the center rotating block 33.

[0044] When the center gear 331 rotates, it drives the coaxially mounted embedded ratchet 333 to rotate in the same direction. The embedded ratchet 333 is embedded in the linkage gear 341 and engages with the embedded pawl 342, thereby driving the linkage gear 341 to rotate in the same direction. Due to the unidirectional transmission of the ratchet wheel and pawl, when the reverse rotation of the linkage gear 341 drives the embedded pawl 342 and the embedded ratchet 333 to reverse, the embedded ratchet 333 and the linkage gear 341 rotate in opposite directions.

[0045] like Figure 7 As shown, the linkage rotating block 34 includes a linkage gear 341, an embedded pawl 342 and a rear spring 343. The linkage gear 341 is installed at one end of the linkage rotating block 34. The embedded pawl 342 is installed in a circular array inside the linkage gear 341 with the central axis of the linkage gear 341 as the center. The embedded pawl 342 can rotate in the opposite direction around the embedded ratchet 333. During the transmission process, when the embedded ratchet 333 rotates, the embedded pawl 342 installed in the circular array engages with the embedded ratchet 333, thereby transmitting the transmission. Torque, since the embedded pawl 342 can only move in one direction, the pawl can only realize one-way transmission, and the pawls distributed in a ring array can provide better support and balance, thereby reducing the wear and deformation of the shock-starting mechanism 3, and the center of the rear spring 343 is fixedly installed on the central axis position of the linkage gear 341, and the linkage gear 341 and the embedded ratchet 333 The springs that rotate in the same direction are continuously energized. When the rear spring 343 is fully energized, a reverse force is applied to the linkage gear 341, thereby restoring the mechanism to its original state.

[0046] like Figure 8As shown, the upper end of the transmission rack 35 is in the shape of an isosceles trapezoidal booster block 351. The isosceles trapezoidal structure design is narrow at the top and wide at the bottom, so that the force of the transmission rack 35 moving upward is concentrated at the upper end, and the inclined waists make the transmission rack 35 bear the load more evenly when transmitting up and down. The upper end of the transmission rack 35 is the isosceles trapezoidal booster block 351, and the lower end of the booster block 351 is installed with the single-sided rack 352, one end of the connecting spring 353 is installed with the lower end of the single-sided rack 352, and the independent tooth installation 354 is connected with the other end of the connecting spring 353. The lower end of the transmission rack 35 is connected with a tooth through a spring, so that after the transmission rack 35 moves to the extreme position, the transmission rack 35 and the linkage gear 341 are elastically meshed, thereby preventing the transmission stability of the transmission rack 35 to the noise reduction mechanism 4 from being affected by the continuous rotation of the linkage gear 341 after the transmission rack 35 moves upward to the extreme position.

[0047] like Fig. 9 As shown, the noise reduction mechanism 4 includes a fixing frame 41, a shrinking block 42, a pushing block 43 and a sound absorbing block 44. The fixing frame 41 is installed inside the outer wall 2, one side of the shrinking block 42 is linearly arrayed with one side of the fixing frame 41, and the pushing block 43 is installed on the other side of the shrinking block 42. The shrinking blocks 42 are evenly spaced and distributed under the restriction of the pushing block 43. Stability: the shrinking blocks 42 installed in a linear array can enhance the stability of the internal structure of the wall, and the shrinking blocks 42 installed in a linear array can reduce the impact of external vibration interference on the inside of the wall. The stability of the bracket helps to reduce the interference of vibration and noise. The present invention takes into account factors such as construction site cost, energy saving and toughness, and adopts glass wool fiber as the main material of the sound-absorbing block 44. The sound-absorbing block 44 is installed at intervals between the fixed frame 41 and the shrinkage block 42. The sound-absorbing blocks 44 installed at intervals can reduce the vibration connection between the fixed frame 41 and the shrinkage block 42, thereby reducing the path of solid noise transmission. The sound-absorbing block 44 made of glass wool fiber material has excellent anti-aging, corrosion resistance, fire resistance and sound absorption performance. The distance between the movable keels 421 is measured, the size of the required sound-absorbing block 44 is designed, and the sound-absorbing block 44 is fixed by pasting glass cloth. Pay attention to the gap fit between the sound-absorbing blocks 44 to ensure the sound absorption and noise reduction effect inside the wall.

[0048] like Fig.10As shown, the fixing frame 41 is a bilaterally symmetrical structure. The bilaterally symmetrical design makes the fixing frame 41 more balanced when subjected to force, reduces deformation and damage caused by eccentric loading or asymmetry, improves the stability of the structure, and the symmetrical design can better maintain accuracy. During the processing and manufacturing process, the bilaterally symmetrical structure can reduce the error caused by stress concentration or asymmetry, thereby ensuring the accuracy and quality of the fixing frame 41. The bilaterally symmetrical fixing frame 41 can better distribute the load and make the force more uniform, which helps to reduce stress concentration and local fatigue inside the sound reduction wall, and improves the life and reliability of the fixing frame 41. The symmetrical design makes the fixing frame 41 more convenient and quick to install. Only by determining the position of the center line and the positioning hole, the fixing frame 41 can be easily installed inside the outer wall 2. The thickness of the fixed keels 411 at both ends of the fixing frame 41 is greater than that of the fixed keel 411 in the middle position. Since sound-absorbing cotton and fixed push blocks 43 need to be installed at both ends of the fixing frame 41, the thickness of the fixed keels 411 at both ends of the fixing block is greater than that in the middle position. Push plate grooves 412 are symmetrically provided at both ends of the fixing frame 41. The push plate slider 432 slides in the push plate groove 412 to limit the movement path of the sliding push plate 431 and provide stability support. Two parallel push rod grooves 413 are fixed in the middle position of the fixing frame 41. The movable keel 421 moves in the parallel push rod grooves 413 through rollers or sliders, so that the movable keel 421 maintains stable and equidistant movement.

[0049] like Fig.11 As shown, the shrinkage block 42 includes a movable keel 421 and a sliding knob. One side of the movable keel 421 is slidably installed on one side of the fixed frame 41. The upper end of the movable keel 421 is "beveled". The beveled design can reduce the contact area between the movable keel 421 and the noise reduction wall, thereby reducing friction. Due to the reduction in contact area, the friction torque between each other will also be reduced accordingly. The beveled design can disperse the pressure on the contact surface to avoid excessive local pressure. This can reduce the wear and deformation of the surface of the object, thereby reducing the frictional resistance. The beveled design can increase the fluidity of the lubricant between the contact surfaces and make the lubricant better distributed on the friction surface, thereby reducing the friction coefficient and achieving the purpose of reducing friction, thereby reducing the noise transmission inside the wall. The sliding knob 422 is fixedly installed at the lower position of the movable keel 421, so that when the push block 43 is below the movable keel 421, the sliding knob 422 is stable at the upper end of the contraction slide rail 433 with a larger gap. When the push plate rises, the sliding knob 422 is at the lower end of the contraction slide rail 433 with a smaller gap, thereby realizing the equal spacing distribution of the movable keel 421 from sparse to dense. A sound-absorbing block 44 is still installed below the movable keel 421 to achieve full absorption of noise inside the noise reduction wall.

[0050] like Fig.12As shown, the pushing block 43 includes a sliding push plate 431, a push plate slider 432, a retracting slide rail 433 and a transmission push groove 434. The sliding push plate 431 is slidably installed on one side of the retracting block 42, and the push plate slider 432 is installed at both ends of one side of the sliding push plate 431. The retracting slide rail 433 is opened on the sliding push plate 431, and the retracting slide rail 433 increases in spacing in the horizontal cross-sectional direction of the sliding push plate 431. The structure of increasing spacing in the horizontal cross-sectional direction allows the retracting block 42 to become sparse or densely distributed with equal spacing from the middle to both sides, and the retracting slide rail 433 has equal spacing in the cross-sectional direction. The shape of the transmission push groove 434 is an isosceles trapezoid that matches the transmission rack 35. Under the sliding cooperation of the two waists of the isosceles trapezoid, the upper end of the transmission rack 35 can be prevented from accidentally contacting or colliding with the lower end of the pushing slide plate, thereby increasing the stability of the linkage between the vibration start mechanism 3 and the noise reduction mechanism 4.

[0051] like Fig.13 and Fig.14 As shown, when the vibration of the construction site is weak and the noise is small, the vibration-starting mechanism 3 maintains a balanced and stable state, and the sound-absorbing blocks 44 in the noise reduction mechanism 4 are densely distributed on both sides and spaced in the middle, so that the smaller noise is absorbed by the sound-absorbing blocks 44 at the outermost side of the noise reduction wall, and the sound waves penetrating the outermost sound-absorbing blocks 44 enter the sound-absorbing blocks 44 distributed in the inner layer and are filtered layer by layer; when the vibration of the construction site is strong and the noise is large, the vibration transmission rack 31 moves up and down due to the vibration of the ground, and the central rotating block 33 keeps rotating under the drive of the auxiliary gear 32 during continuous vibration, and the transmission rack 35 moves upward to push the pushing block 43 moves upward, so that the movable keel 421, under the limitation of the retracting slide rail 433, is gathered from a loose and evenly spaced distribution to an evenly spaced distribution in the middle, thereby increasing the distance between the push plate and the lower end of the wall and the movable keel 421 and the two sides of the wall, thereby interrupting the propagation sound bridge of the noise through the solid structure inside the wall to a certain extent. At the same time, the sound-absorbing blocks 44 are driven by the movable keel 421 to be distributed twice in the noise reduction wall at intervals on both sides to the middle. Therefore, after the noise is sucked from the interval, it is attenuated by the sound absorption of the layers of sound-absorbing blocks 44, thereby achieving the effect of sound insulation and noise reduction of the noise reduction wall.

[0052] During the working process of the present invention, the construction site generates noise transmission due to the construction vibration, and the vibration transmission rack 31 in the vibration start mechanism 3 moves upward due to the ground vibration, so that the half-toothed gear 321 on one side of the auxiliary gear 32 that meshes with the vibration transmission rack 31 rotates, and at the same time, the central gear 331 is driven to rotate, and the full-toothed gear 322 symmetrically installed on the other side is driven to rotate by the central gear 331, so that the half-toothed gear 321 coaxially fixedly installed with the full-toothed gear 322 rotates until the tooth surface meshes with the vibration transmission rack 31, so that when the ground maintains a certain amplitude and vibration, the up and down movement of the vibration transmission rack 31 is converted into the central gear The rotating central gear 331 drives the coaxially mounted embedded ratchet 333 to rotate, and the one-way transmission of the embedded ratchet 333 and the embedded pawl 342 drives the linkage gear 341 to rotate in the same direction. At the same time, the transmission rack 35 is driven to move upward and the rear spring 343 is continuously energized by the continuous rotation of the linkage gear 341, so that the transmission rack 35 is upwardly connected to the noise reduction mechanism 4 and maintained for a period of time, and then the linkage gear 341 drives the embedded pawl 342 and the embedded ratchet 333 to rotate in the opposite direction, so that the transmission rack 35 drives the pushing block 43 in the noise reduction mechanism 4 to move downward and return to its original position.

[0053] When the vibration-starting mechanism 3 detects a certain amplitude and continuous vibration of the ground, the pushing block 43 moves upward. The contraction block 42 distributed in a linear array is restricted by the contraction slide rail 433, and the movable keels 421 in the contraction block 42 move from both sides to the middle and are evenly spaced, so that the sound-absorbing blocks 44 installed on both sides of the contraction block 42 are distributed at intervals, and the sound-absorbing blocks 44 installed between the movable keels 421 in the contraction block 42 are densely distributed. When the construction vibration stops, the pushing block 43 is driven downward by the transmission rack 35 in the vibration-starting mechanism 3 to return to its original position. Under the restriction of the contraction slide rail 433, the movable keels 421 of the contraction block 42 are evacuated from the middle position to both sides at equal intervals. At this time, the sound-absorbing blocks 44 on both sides of the contraction block 42 are densely distributed, and the sound-absorbing blocks 44 between the movable keels 421 in the contraction block 42 are distributed at intervals.
