[0029] Embodiment: Please refer to Figures 1 to 10 as shown:

[0030] The present invention provides a sound insulation wall for buildings, which includes a main sound insulation wall 1. An upper worm 101 is rotatably arranged on the upper part of the main sound insulation wall 1. The main sound insulation wall 1 is in a plate-like structure. A first one-way valve 102 is arranged at the front of the main sound insulation wall 1. The first one-way valve 102 becomes in a conducting state by pushing open the check valve and closing the air valve needle by an external force. A second one-way valve 103 is arranged at the back of the main sound insulation wall 1. The second one-way valve 103 is a valve body for one-way air outlet. Outer pipe bodies 104 are arranged at intervals on the back of the main sound insulation wall 1. The water liquid inside the outer pipe bodies 104 can keep the temperature of the upper sound insulation wall 2 stable, reduce the influence of thermal expansion and contraction, and reduce the temperature difference influence on the inner support capsule 4 and the main sound insulation wall 1. The outer pipe bodies 104 are hollow tubular structures with sealed bottoms. An outer baffle 105 is slidably arranged inside the outer pipe bodies 104. The outer baffle 105 can be in an arc structure. The outer baffle 105 moves vertically along the inside of the outer pipe bodies 104. An inner cavity 106 is arranged inside the main sound insulation wall 1. An upper sound insulation wall 2 is arranged at the top of the main sound insulation wall 1. The upper sound insulation wall 2 is in a plate-like structure. A middle worm gear shaft 201 is fixed at the head end of the upper sound insulation wall 2. A back support strip 202 is fixed at the back of the upper sound insulation wall 2. The tail end of the back support strip 202 is rotatably connected to the head end of a connecting rotating strip 203. By rotating the upper worm 101, the upper worm 101 meshes with and drives the middle worm gear shaft 201 to rotate. The middle worm gear shaft 201 and the upper sound insulation wall 2 rotate synchronously around the middle worm gear shaft 201 as the center to adjust the inclination angle, so that the upper sound insulation wall 2 performs sound insulation adjustment at different inclination angles. The upper sound insulation wall 2 and the main sound insulation wall 1 cooperate to form a flat wall structure or are converted into a wall structure with a curved top, improving compatibility, meeting the sound insulation requirements of different municipal sections, reducing the spare part cost of sound insulation walls of different bending types, and making it more convenient to replace a single type of sound insulation wall in case of later damage. The tail end of the connecting rotating strip 203 is rotatably connected to the upper end of the outer baffle 105. The middle worm gear shaft 201 is rotatably connected to the upper part of the main sound insulation wall 1. The worm gear at the head end of the middle worm gear shaft 201 is meshed and connected with the upper worm 101. The upper worm 101 drives the middle worm gear shaft 201 to rotate. The middle worm gear shaft 201 and the upper sound insulation wall 2 rotate synchronously to adjust the inclination angle. The upper sound insulation wall 2 pulls the outer baffle 105 to move upward through the back support strip 202 and the connecting rotating strip 203. The outer baffle 105 moves upward to the outside of the upper part of the outer pipe body 104. The outer pipe body 104 guides the water flow of the inclined upper sound insulation wall 2 into the outer pipe body 104;

[0031] On both sides of the main sound insulation wall 1, side fixing frames 3 are provided. Outer fixing plates 301 are arranged at the front and rear of the side fixing frames 3, and lower fixing plates 302 are arranged on both sides of the bottom of the side fixing frames 3. The side fixing frames 3 and the outer fixing plates 301 form an H-shaped structure. The outer fixing plates 301 are located at the front and rear of the main sound insulation wall 1. The side fixing frames 3 are bolt-fixed to the municipal elevated road surface through the lower fixing plates 302. The upper sound insulation wall 2 is hoisted and inserted between the two outer fixing plates 301 of the side fixing frames 3 by upper sliding. The two sides of the upper sound insulation wall 2 are fixed by the side fixing frames 3. An inner support bladder 4 is arranged inside the main sound insulation wall 1. Support cylindrical bladders 401 are arranged at intervals in an array in the inner support bladder 4. The tail ends of the support cylindrical bladders 401 are fixedly connected to the rear sliding plate 402. The front part of the inner support bladder 4 is fixed to the inner cavity 106. The support cylindrical bladders 401 expand to support the movement of the rear sliding plate 402. The inner support bladder 4, the support cylindrical bladders 401 and the rear sliding plate 402 are all located inside the inner cavity 106. The inner support bladder 4 and the support cylindrical bladders 401 are connected in a through manner. The rear sliding plate 402 slides horizontally inside the inner cavity 106. A sealing strip is arranged around the outside of the rear sliding plate 402. The sealing strip around the outside of the rear sliding plate 402 is in sliding seal with the inner cavity 106. The rear sliding plate 402 partitions the front and rear inner cavities 106 into two non-connected areas. The first one-way valve 102 is connected to the inner support bladder 4 in a through manner. The second one-way valve 103 is connected to the rear part of the inner cavity 106 in a through manner. The second one-way valve 103 is located at the rear of the rear sliding plate 402. When the rear sliding plate 402 slides, the air in the inner cavity 106 is squeezed to the outside through the second one-way valve 103.

[0032] Among them, when the upper worm 101 rotates, the middle worm gear shaft 201 and the upper sound insulation wall 2 rotate synchronously to the front side of the main sound insulation wall 1. The outer baffle 105 moves up to the upper part of the outer tube 104, and the outer baffle 105 moves up to the rear of the upper sound insulation wall 2. When the outer baffle 105 moves up, the rainwater after tilting the upper sound insulation wall 2 is guided into the outer tube 104. The accumulated water inside the outer tube 104 can increase the weight and stability of the upper sound insulation wall 2.

[0033] Among them, when the inner support bladder 4 is filled with liquid and expands through the first one-way valve 102, the inner support bladder 4 and the support cylindrical bladders 401 support the rear sliding plate 402 to move towards the side of the second one-way valve 103. When the rear sliding plate 402 slides, the air in the inner cavity 106 is squeezed to the outside through the second one-way valve 103. The support cylindrical bladders 401 support the rear sliding plate 402 to expand the distance from the front part of the inner cavity 106. The distance between the rear sliding plate 402 and the front part of the inner cavity 106 expands, but the air inside remains unchanged, so that a low-pressure area similar to a vacuum is formed between the rear sliding plate 402 and the front part of the inner cavity 106. This area can reduce the transmission of sound and improve the sound insulation effect. When the inner support bladder 4 is in a contracted state, the rear sliding plate 402 moves towards the side of the inner support bladder 4. When the inner support bladder 4 is in a contracted and unfilled state, it can reduce the weight and facilitate transportation and installation.

[0034] Specific usage and functions of this embodiment: The side fixing frame 3 is bolt-fixed to the municipal elevated road surface through the lower fixing plate 302. The upper sound insulation wall 2 is hoisted and inserted between the two outer fixing plates 301 of the side fixing frame 3 by sliding upwards. The two sides of the upper sound insulation wall 2 are fixed by the side fixing frame 3. The main sound insulation wall 1 and the upper sound insulation wall 2 are arranged on both sides of buildings such as municipal roads or elevated roads. The main sound insulation wall 1 and the upper sound insulation wall 2 block the transmission of vehicle driving noise to both sides, reducing the noise of the surrounding residential buildings. Rotate the upper worm 101, and the upper worm 101 drives the middle worm gear shaft 201 to rotate through meshing. The middle worm gear shaft 201 and the upper sound insulation wall 2 rotate synchronously around the middle worm gear shaft 201 as the center to adjust the inclination angle, so that the upper sound insulation wall 2 can perform sound insulation adjustment at different inclination angles. The upper sound insulation wall 2 and the main sound insulation wall 1 cooperate to form a flat wall structure or be converted into a wall structure with a curved top, improving compatibility, meeting the building sound insulation requirements of different municipal sections, enhancing the versatility of components, reducing the spare part cost for different types of curved sound insulation walls, and making it more convenient to replace damaged parts of a single type of sound insulation wall in the later stage;

[0035] When the upper sound insulation wall 2 rotates, the upper sound insulation wall 2 and the back support bar 202 rotate synchronously. The back support bar 202 pulls the outer baffle 105 to move upwards synchronously through the connecting rotating bar 203. The upward movement of the outer baffle 105 guides the rainwater after the upper sound insulation wall 2 is tilted into the outer pipe body 104. The accumulated water inside the outer pipe body 104 can increase the weight and stability of the upper sound insulation wall 2. At the same time, the liquid inside the outer pipe body 104 can keep the temperature of the upper sound insulation wall 2 stable, reducing the influence of thermal expansion and contraction, and reducing the temperature difference influence on the inner support bladder 4 and the main sound insulation wall 1;

[0036] When the inner support bladder 4 is filled with liquid through the first one-way valve 102 and enters the expanded state, the inner support bladder 4 and the support cylindrical bladder 401 support the rear sliding plate 402 to move towards the side of the second one-way valve 103. The sliding of the rear sliding plate 402 squeezes the air in the inner cavity 106 to the outside through the second one-way valve 103. The support cylindrical bladder 401 supports the rear sliding plate 402 to expand the distance between the front part of the inner cavity 106. The distance between the rear sliding plate 402 and the front part of the inner cavity 106 expands, but the air inside remains unchanged, forming a low-pressure area similar to a vacuum between the rear sliding plate 402 and the front part of the inner cavity 106. This area can reduce the transmission of sound and improve the sound insulation effect; Oil or air can be filled inside the inner support bladder 4 and the support cylindrical bladder 401, and different substances can be filled according to different cost budgets. After the inner support bladder 4 and the support cylindrical bladder 401 expand, they form multiple sound insulation layers with the main sound insulation wall 1 and the rear sliding plate 402, improving the sound insulation effect. When the inner support bladder 4 contracts without filling, it can reduce the weight and facilitate transportation and installation.

[0037] In another embodiment, the rear slide plate 402 can also be slidably sleeved on the main sound insulation wall 1. The rear slide plate 402 and the main sound insulation wall 1 are supported by the inner support bladder 4 and the support cylindrical bladder 401 to slide and expand the distance, forming a low-pressure area similar to a vacuum. At the same time, when the inner support bladder 4 and the support cylindrical bladder 401 contract, the distance between the rear slide plate 402 and the main sound insulation wall 1 can be reduced, reducing the overall thickness. A lower thickness can transport a larger quantity, improving the transportation efficiency.
