Description

Technical Field

[0001] The technical field involved in the present invention particularly relates to a single-opening sound-absorbing window with micro-hole resonance cavity ventilation. Background Art

[0002] In recent years, urban transportation has developed rapidly, and the resulting traffic noise pollution has become increasingly serious. At the same time, good indoor ventilation is a necessary requirement for daily life. For this reason, the technology of ventilation sound-absorbing windows has become a commonly used indoor noise reduction measure for buildings in noise pollution areas. Generally, ventilation sound-absorbing windows can be divided into two types according to their ventilation characteristics: mechanical ventilation and natural ventilation.

[0003] Well-known industrial and civil ordinary windows have functions of lighting, ventilation and heat preservation, but their sound insulation effect is poor. Especially when the window is opened for ventilation, it does not have the function of sound insulation. Outdoor environmental noise can directly enter the room and cause indoor noise pollution. When there are high-noise sources indoors, they also directly radiate to the outdoor environment and pollute it. Summary of the Invention

[0032] Embodiment 1

[0033] Refer to Figures 1-4, a schematic diagram of the overall structure of a microporous resonance cavity ventilation single-opening soundproof window is provided, including a window body 100, which includes a window frame 101, an external opening window 102 arranged on the outer side of the window frame 101 near the boundary of the window frame 101, an internal opening window 103 arranged on the inner side of the window frame 101 near the boundary of the window frame 101, and a soundproof window 104 arranged in the middle section on the inner and outer sides of the window frame 101. A light-transmitting window 105 is arranged at the upper end of the window frame 101, and a ventilation duct 106 is formed between the external opening window 102 and the internal opening window 103; a driving assembly 200 for driving the external opening window 102 to open is arranged at the lower end of the window frame 101; and a soundproof assembly 300, the soundproof assembly 300 is arranged in the soundproof window 104. The external opening window 102 includes a first externally rotating window 102a arranged near the left side of the window frame 101 and a second externally rotating window 102b arranged near the right side of the window frame 101. The internal opening window 103 includes a first internally rotating window 103a arranged near the left side of the window frame 101 and a second internally rotating window 103b arranged near the right side of the window frame 101. Among them, the driving assembly 200 is arranged between the first externally rotating window 102a and the second internally rotating window 103b and between the second externally rotating window 102b and the first internally rotating window 103a.

[0034] Specifically, the main structure of the present invention includes a window body 100. The window body 100 includes a window frame 101. The window frame 101 is a square structure as a whole, and the window frame 101 is divided into two layers inside and outside. Then, an external opening window 102 is also rotatably connected near the boundary of the window frame 101 on the outer side of the window frame 101. In this embodiment, the external opening window 102 includes a first externally rotating window 102a rotatably connected to the left side of the window frame 101 and a second externally rotating window 102b rotatably connected to the right side of the window frame 101. The rotation planes of the first externally rotating window 102a and the second externally rotating window 102b are both horizontally arranged. The external opening window 102 can be opened outward. At the same time, the thickness of the external opening window 102 is 2 mm thicker than the thickness of the internal opening window 103. The purpose of this setting is to block sound waves of different frequencies according to the different sound insulation effects of glass with different thicknesses.

[0035] Furthermore, an internal opening window 103 is also arranged on the inner side of the window frame 101 and near the boundary of the window frame 101. In this embodiment, the internal opening window 103 includes a first internally rotating window 103a rotatably connected to the left side inside the window frame 101 and a second internally rotating window 103b rotatably connected to the right side inside the window frame 101. The rotation planes of the first internally rotating window 103a and the second internally rotating window 103b are horizontally arranged. The first internally rotating window 103a and the second internally rotating window 103b are manually opened or closed by the operator. And soundproof windows 104 are also arranged in the middle sections on the inner and outer sides of the window frame 101, and a soundproof assembly 300 is also arranged in the soundproof window 104. Then, a ventilation duct 106 is formed between the external opening window 102 and the internal opening window 103 inside the window frame 101. When the first externally rotating window 102a and the second internally rotating

[0036] After the window 103b is opened or the second outward-rotating window 102b and the first inward-rotating window 103a are opened, the outside wind enters the ventilation duct 106 and passes through

[0037] the sound-absorbing window 104, and then enters the room through the inward-opening window 103. At the same time, in order to ensure light transmission, a light-transmitting window 105 is also provided at the upper end of the window frame 101. The light-transmitting window 105 is divided into three parts and is respectively arranged at the upper end of the window frame 101.

[0038] It should be noted that in the present invention, the micro-perforated resonance cavity ventilation single-opening type sound-absorbing window 104 can only achieve sound absorption while ventilating when the first outward-rotating window 102a and the second inward-rotating window 103b are opened or the second outward-rotating window 102b and the first inward-rotating window 103a are opened. The outside sound passes through the ventilation duct 106 and the sound-absorbing window 104. After the outward-opening window 102 and the inward-opening window 103 are jointly closed, only the sealing and sound insulation operation is performed.

[0039] Furthermore, in order to enable the corresponding outward-opening window 102 to be opened after the operator opens the inward-opening window 103, a driving assembly 200 is also provided at the lower end of the window frame 101, thereby facilitating the operator's use.

[0040] Operation process: When the operator needs to open the window for ventilation, the operator opens the first inward-rotating window 103a or the second inward-rotating window 103b, and drives the opening of the second outward-rotating window 102b or the first outward-rotating window 102a through the driving assembly 200. At this time, the outside air flow and sound enter the ventilation duct 106 through the first outward-rotating window 102a or the second outward-rotating window 102b, and then pass through the sound-absorbing window 104 and the sound-absorbing assembly 300 to achieve sound absorption, and then flow into the room through the first inward-rotating window 103a or the second inward-rotating window 103b, thereby achieving sound absorption while ensuring ventilation.

[0041] Embodiment 2

[0042] Refer to Figure 2 and Figure 4, what is different from the first embodiment in this embodiment is that the sound-absorbing window 104 includes an outer window 104a provided on the outer side of the window frame 101 and an inner window 104b provided on the inner side of the window frame 101. The sound-absorbing component 300 includes a micro-perforated plate 301 provided at the position of the window frame 101 near the middle between the inner window 104b and the outer window 104a. Sound-absorbing holes 302 are formed in the micro-perforated plate 301. The shape of the sound-absorbing holes 302 is circular. Both sides of each micro-perforated plate 301 are respectively connected to both sides of the inner window 104b and both sides of the outer window 104a. The micro-perforated plate 301 is a transparent plate. The first outer rotating window 102a and the second outer rotating window 102b are both inclined at one end close to the outer window 104a. The angle between the vertical plane where the first outer rotating window 102a or the second outer rotating window 102b is located and the vertical plane where the outer window 104a is located is 3°-5°.

[0043] Specifically, in this embodiment, the sound-absorbing window 104 includes an outer window 104a provided near the outer side of the window frame 101 and an inner window 104b provided near the inner side of the window frame 101. Neither the inner window 104b nor the outer window 104a can be opened, and the sound-absorbing component 300 is provided between the inner window 104b and the outer window 104a. In this embodiment, the sound-absorbing component 300 includes micro-perforated plates 301. There are two micro-perforated plates 301 and they are transparent plates. The materials are transparent materials with a certain strength such as plexiglass, tempered glass, and PVC. They are respectively provided on one side of the outer window 104a close to the inner window 104b and on one side of the inner window 104b provided on the outer window 104a. The micro-perforated plates 301 are arranged parallel to the inner window 104b or the outer window 104a, and the distance between them is 30 mm - 80 mm. The peripheries of the micro-perforated plates 301 are fixed and sealed with the peripheries of the inner window 104b or the outer window 104a. Thus, a resonance cavity is formed between the micro-perforated plates 301 and the inner window 104b or the outer window 104a. A number of sound-absorbing holes 302 are also formed in the micro-perforated plates 301. The aperture of the sound-absorbing holes 302 is less than 1 mm, and the perforation rate is less than 5%. The sound-absorbing holes 302 penetrate through the micro-perforated plates 301 and the shape is circular. When external sound waves enter the ventilation duct 106, they are incident on the air mass block in the sound-absorbing holes 302. The energy of the sound waves will drive the air mass block to rub back and forth with the hole wall of the sound-absorbing holes 302 to convert the sound energy into heat energy and dissipate it. Then the sound waves enter the resonance cavity. The resonance frequency of the absorption peak is controlled by the cavity depth, the absorption coefficient ≥ 0.9, and the absorption frequency bandwidth is 4 - 5 octaves. Then the sound waves are continuously reflected between the micro-perforated plates 301 and the inner window 104b or the outer window 104a, thereby realizing the energy consumption of the sound waves, and thus achieving the purpose of sound attenuation. At the same time, the larger the areas of the inner window 104b and the outer window 104a are, the more the sound-absorbing holes 302 are provided, and thus the better the sound-absorbing effect is.

[0044] Furthermore, the first outward-rotating window 102a, the outer window 104a, and the second outward-rotating window 102b are all inclined at one end close to the outer window 104a. That is, the angle between the vertical planes where the first outward-rotating window 102a, the second outward-rotating window 102b, and the outer window 104a are located and the vertical plane of the outer surface of the window frame 101 is 3°-5°. If the outer window 104a and the inner window 104b are arranged in parallel, a standing wave phenomenon will occur between them, which will reduce the noise reduction effect. The inclined setting will prevent a standing wave phenomenon from occurring between the outer window 104a and the inner window 104b. Moreover, this setting can reduce sound and improve the overall noise reduction efficiency of the window. At the same time, the inclined setting of the first outward-rotating window 102a and the second outward-rotating window 102b can make the glass protrude outward, so that it will not be blocked by the external window frame 101 or the wall, thereby enhancing the lighting and light transmission effect of the glass.

[0045] A standing wave phenomenon will be formed, which will reduce the noise reduction effect. The inclined setting will prevent a standing wave phenomenon from occurring between the outer window 104a and the inner window 104b.

[0046] Moreover, this setting can reduce sound and improve the overall noise reduction efficiency of the window. At the same time, the inclined setting of the first outward-rotating window 102a and the second outward-rotating window 102b can make the glass protrude outward, so that it will not be blocked by the external window frame 101 or the wall, thereby enhancing the lighting and light transmission effect of the glass.

[0047] Preferably, sound-absorbing materials are also pasted around the inside of the window frame 101. In this embodiment, the sound-absorbing materials are selected as sound-absorbing felts or externally pressed perforated aluminum plates, which can cooperate with the sound-absorbing window 104 to play a sound-absorbing role and also have a certain sealing effect, sealing the small gaps between the window frame 101 and the outward-opening window 102 and the inward-opening window 103.

[0048] The remaining structures are the same as those in Embodiment 1.

[0049] Specifically, after the sound wave enters the ventilation duct 106 from the outside, it is first preliminarily sound-insulated by the sound-absorbing materials in the window frame 101. And the sound wave is first reflected between the outward-opening window 102 and the inward-opening window 103 for preliminary noise reduction, and then it is incident on the air mass block in the sound-absorbing hole 302, driving the air mass block to rub back and forth with the hole wall to convert the sound energy into heat energy and dissipate it. Then the sound wave is continuously reflected in the resonance cavity, and the energy of the sound wave will gradually decrease, thereby achieving the noise reduction effect.

The rotation planes of the first guide wheel 201 and the second guide wheel 202 are both horizontal. Then, a transmission belt 203 is further connected between the first guide wheel 201 and the second guide wheel 202. The rotation between the first guide wheel 201 or the second guide wheel 202 can be transmitted by the transmission belt 203, and the rotation directions of the first guide wheel 201 and the second guide wheel 202 are the same due to the transmission belt 203. At the same time, a rotating shaft 204 is also provided at the central rotation of the first guide wheel 201 and the second guide wheel 202. The rotating shaft 204 is vertically arranged, the upper end is rotatably connected to the upper edge of the window frame 101, the lower end is rotatably connected to the lower edge of the window frame 101, and the rotating shaft 204 can rotate together with the rotation of the first guide wheel 201 or the second guide wheel 202.

[0053] Further, a first snap ring 205 is fixed to the rear ends of the first outer rotating window 102a and the second outer rotating window 102b, and a second snap ring 206 is fixed to the rear ends of the first inner rotating window 103a and the second inner rotating window 103b. Both the first snap ring 205 and the second snap ring 206 are sleeved on the rotating shaft 204, and the first snap ring 205 is positioned above the second snap ring 206. Then, a connecting ring 400 is slidably connected to the middle section of the rotating shaft 204 in the vertical direction. A key 401 is fixed to the upper surface of the connecting ring 400, and a key 401 is also fixed to the lower surface of the connecting ring 400.

After the connecting ring 400 slides

[0054] back and forth, the key 401 will be connected to the first keyway 402 or the second keyway 403, and thus the rotation of the connecting ring 400 will drive the rotation of the first

[0055] snap ring 205 or the second snap ring 206.

[0056] Further, a sliding member 500 for driving the sliding of the connecting ring 400 is provided on the window frame 101. In this embodiment, the sliding member 500 includes a gear 501 rotatably connected to the lower end of the window frame 101.

Then, a rod 503 is fixed to the side wall of each rack 502. The rod 503 is L-shaped, and the end of the rod 503 close to the rack 502 is perpendicular to the length direction of the rack 502. Then, the other end of the rod 503 is inserted into the inside of the rotating shaft 204 and is slidably connected to the inside of the rotating shaft 204 in the vertical direction. Then, the upper end of the rod 503 is also rotatably connected to a connecting rod. The rotation plane of the connecting rod is horizontally arranged, and after the connecting rod extends horizontally out of the rotating shaft 204, it is connected to the connecting ring 400.

[0057] Preferably, a spring 504 is also connected between the gear 501 and the window frame 101. When the gear 501 is not rotated by an external force, the gear 501 is in the initial position. At this time, the spring 504 will pull one of the racks 502, causing the rack 502 to drive the sliding of the rod 503, causing the rod 503 to drive the sliding of the connecting ring 400, and making the connecting ring 400 located between the first snap ring 205 and the second snap ring 206. At this time, the key 401 does not cooperate with the first keyway 402 or the second keyway 403.

[0058] The rest of the structure is the same as that in Embodiment 3.

[0059] Operation process: When it is necessary to open the first inner rotating window 103a or the second outer rotating window 102b, the operator rotates the gear 501 to make the gear 501 rotate forward. Then, the rack 502 on the left side of the gear 501 moves downward, and then the rack 502 on the right side of the gear 501 moves upward. Then, the left rack bar 503 is pulled to drive the connecting ring 400 to move downward by the left rack bar 503, so that the key 401 on the connecting ring 400 is engaged with the second key groove 403. At this time, the second snap ring 206 on the first inner rotating window 103a is connected to the rotating shaft 204. At the same time, the rack 502 on the right side of the gear 501 moves upward, so that the right rack bar 503 drives the connecting ring 400 to move upward, and the key 401 on the right connecting ring 400 is engaged with the first key groove 402. At this time, the first snap ring 205 on the right second outer rotating window 102b is connected to the rotating shaft 204. At this time, the operator manually opens the first inner rotating window 103a, and the first inner rotating window 103a rotates, driving the rotation of the rotating shaft 204. At this time, the first guide wheel 201 rotates, and then drives the second guide wheel 202 to rotate through the transmission belt 203. Because the first guide wheel 201 and the second guide wheel 202 rotate in the same direction, the second outer rotating window 102b is driven to rotate outwards at this time, and the window opening action is completed at this time; when opening the second inner rotating window 103b or the first outer rotating window 102a, only need to reverse the gear 501, and then it can be opened. The operation process is similar to the above method and will not be elaborated.

[0060] Embodiment 4

[0061] Refer to Figure 2 and Figure 8 This embodiment is different from the above embodiments in that: an operating rod 506 is provided on the rotating shaft 204 of the gear 501 extending outwards from the window frame 101. A lock groove 600 is formed on the operating rod 506. A lock block 601 is slidably connected in the lock groove 600. An elastic member 602 is connected between the lock block 601 and the lock groove 600. Among them, a locking groove 603 matching the lock block 601 is formed at the lower end of the window frame 101. The number of the locking grooves 603 is two, and they are symmetrically arranged with respect to the center line of the window frame 101 respectively. A rubber pad 604 is provided on the lock block 601.

[0062] Specifically, an operating rod 506 is provided on the rotating shaft 204 of the gear 501 extending outwards from the window frame 101. Thus, the operator can rotate the gear 501 by controlling the operating rod 506. At the same time, a lock groove 600 is also formed on the operating rod 506. The lock groove 600 is formed on the side wall. Then, a lock block 601 is also slidably connected in the lock groove 600. After the lock block 601 slides, it will extend out of the lock groove 600, and it can also completely retract into the lock groove 600 after sliding. Then, an elastic member 602 is also connected between the lock block 601 and the lock groove 600. In this embodiment, the elastic member 602 is a tension spring 504, which drives the lock block 601 to pop out of the lock groove 600.

[0063] Further, locking grooves 603 cooperating with the lock block 601 are also provided at the lower end of the window frame 101. There are two locking grooves 603, which are respectively arranged on both sides of the rotating shaft 204 of the gear 501. The two locking grooves 603 are symmetrically arranged with respect to the center line of the window frame 101, and the locking grooves 603 are all arranged in the horizontal direction. Then, a rubber pad 604 is also attached to the outer side of the lock block 601, and the rubber pad 604 can make

[0064] the cooperation between the lock block 601 and the locking groove 603 more stable.

[0065] The rest of the structure is the same as that of Embodiment 3.

[0066] Operation process: When the operator rotates the gear 501, the operator rotates the operating rod 506, rotates it to the left or right. After rotating to the left, it will cause the gear 501 to rotate forward and reverse, causing the left rack 502 to move downward and the right rack 502 to move upward; after rotating to the right, it will cause the gear 501 to rotate in the reverse direction, causing the left rack 502 to move upward and the right rack 502 to move downward. At the same time, when moving to the locking groove 603, the lock block 601 pops out outward, so that the lock block 601 cooperates with the locking groove 603 to lock the position of the gear 501. Furthermore, at this time, the connecting ring 400 driven by the support rod 503 cooperates with the first snap ring 205 or the second snap ring 206. When unlocking is required, the operator presses the lock block 601 in the reverse direction to make the lock block 601 retract into the lock groove 600. At this time, the rotating shaft 204 of the gear 501 can be rotated.
