Description

Technical Field

[0001] The utility model relates to the technical field of acoustics, in particular to a perforated sound-absorbing wedge plate structure. Background Art

[0002] Porous materials are filled with narrow gaps, and the propagation of sound in them causes the vibration of air molecules. The viscosity effect of the air in the narrow gaps can greatly convert sound energy into heat energy, achieving the purpose of efficient and broadband sound absorption. Porous materials have the advantages of excellent sound absorption and low production cost. They are commonly used sound absorption materials in hall design, rail transportation and manufacturing. When using porous materials to construct sound absorbers, in order to adjust the surface acoustic impedance of the sound absorber to ensure that the sound waves can enter the sound absorber more "smoothly" to achieve full energy dissipation, the shape of the sound absorber is usually designed into a "wedge" shape.

[0003] For example, Chinese patent publication number CN103452199A discloses a sound-absorbing wedge, which includes a base and a tip connected to the base, and a sound-absorbing board is installed on the surface of the base and the tip, and the sound-absorbing board is made of polyester fiber material and has multiple evenly arranged perforations. Since polyester fiber is a material with many micropores, the sound-absorbing board has a good sound-absorbing effect, and the perforations are arranged on the surface of the sound-absorbing board. Therefore, the improved sound-absorbing wedge reduces the reflection of noise, and compared with the metal wedge, the noise absorption rate is increased by at least 20%.

[0004] The existing technology has the following problems:

[0005] The rear side of the sound-absorbing wedge is fixedly connected to the base. When the perforated sound-absorbing wedge is placed and used for a long time, dust and debris will accumulate inside the sound-absorbing hole to a greater or lesser extent. At the same time, the wedge is not conducive to disassembly or internal cleaning, resulting in the inside of the hole being filled, which becomes conducive to the transmission of sound, thereby failing to achieve the original intention of using effective sound absorption.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1 , Figure 2 As shown, a perforated sound-absorbing wedge plate structure comprises a wedge body 1, an outer side of the wedge body 1 near the rear side is fixedly connected to a surrounding plate 2, an outer side of the surrounding plate 2 is movably sleeved with a mounting frame 3, and inner sides of left and right walls of the mounting frame 3 are movably sleeved with a fixing mechanism 4, a lower surface of the wedge body 1 is provided with a water-permeable hole 5 at a rear side near the left and right sides, and the front side of the wedge body 1 is movably sleeved with two left-right symmetrical placement mechanisms 6.

[0029] It should be noted that the wedge body 1 adopts a double-wedge structure, and each placement mechanism 6 corresponds to a separate wedge on the wedge body 1 .

[0030] like Figure 2 , Figure 3 As shown, the fixing mechanism 4 includes a block 42, the outer side of the block 42 is movably sleeved in the inner cavity near the upper end of the left and right walls of the installation frame 3, the lower surface of the block 42 is overlapped on the upper side of the enclosure 2, and two blocks 42 are symmetrically distributed on the left and right sides, two first limit rods 41 are movably sleeved on both sides of the upper sides of the two blocks 42, and the left and right ends of the first limit rods 41 are fixedly connected to the left and right sides of the inner sides of the left and right walls of the installation frame 3, the outer walls of the four first limit rods 41 are movably sleeved with first springs 43, and the first springs 43 are located on the side of the block 42 away from the wedge body 1, and the front sides of the two blocks 42 are fixedly connected with push buttons 44, and the push buttons 44 are located on the front side of the installation frame 3.

[0031] It should be noted that the stopper 42 is located on the upper side of the enclosure 2, so that the upper side of the enclosure 2 is blocked, and the wedge body 1 cannot drive the enclosure 2 to be pulled out from the inner side of the installation frame 3. Pushing the push button 44 to the side away from the wedge body 1 causes the stopper 42 to be detached from the upper side of the enclosure 2. At this time, the wedge body 1 can drive the enclosure 2 to be pulled out from the inner side of the installation frame 3.

[0032] like Figure 2 , Figure 3As shown, the shape of the stopper 42 is a right-angled trapezoid, and the inclined surface of the stopper 42 is located at the upper side close to one side of the wedge body 1.

[0033] It should be noted that the shape of the stopper 42 is such that when the enclosure 2 is placed in, the lower left and right edges of the enclosure 2 can push the stopper 42 so that the stopper 42 enters the inner side of the left and right walls of the installation frame 3, until the enclosure 2 is completely placed in the inner side of the installation frame 3, and the first spring 43 pushes the stopper 42 to return to its original position.

[0034] like Figure 2 , Figure 4 As shown, a pop-up assembly 45 is fixedly connected to the inner side of the lower wall of the mounting frame 3, and the pop-up assembly 45 includes a second limiting rod 451, and both ends of the upper ends of the second limiting rod 451 are fixedly connected to the upper and lower surfaces of the inner side of the lower wall of the mounting frame 3, and two second limiting rods 451 are symmetrically distributed on the left and right, and a top block 452 is movably sleeved on the outer side of the second limiting rod 451, and the upper surface of the top block 452 is attached to the lower surface of the enclosure 2, and the outer walls of the two second limiting rods 451 are movably sleeved with a second spring 453, and the second spring 453 is located on the lower side of the top block 452.

[0035] It should be noted that when the stop block 42 is separated from the upper side of the enclosure 2, the second spring 453 pushes the top block 452 upward, and the top block 452 pushes the enclosure 2 upward. At this time, the side of the enclosure 2 supports the stop block 42 to prevent the stop block 42 from moving back to the upper side of the enclosure 2 when the first spring 43 pushes the stop block 42 to return to its original position.

[0036] like Figure 2 , Figure 5 As shown, the placement mechanism 6 includes a sealing plate 61, the outer wall of the sealing plate 61 is movably sleeved on the front wall of the wedge body 1 near the left and right sides, the rear side of the sealing plate 61 near the bottom is fixedly connected with a placement box 62, the lower side of the placement box 62 is slidably connected to the inner lower surface of the wedge body 1, and the inner side of the placement box 62 is movably sleeved with a moisture absorption plate 63.

[0037] It should be noted that the moisture absorbing plate 63 absorbs the water vapor inside the wedge body 1 to keep the inside of the wedge body 1 dry. The sealing plate 61 can drive the placement box 62 to pull out the moisture absorbing plate 63, so as to facilitate the replacement of the moisture absorbing plate 63.

[0038] like Figure 2 , Figure 5 and Figure 7As shown, a fixing component 64 is fixedly connected in the lower inner cavity of the sealing plate 61, and the fixing component 64 includes a third limiting rod 641, and the upper and lower ends of the third limiting rod 641 are fixedly connected to the upper and lower surfaces of the lower inner cavity of the sealing plate 61, and two third limiting rods 641 are symmetrically distributed on the left and right, and the outer side of the third limiting rod 641 is movably sleeved with an insert block 642, and the outer side of the insert block 642 is movably sleeved near the bottom in a slot opened at the bottom of the front wall of the wedge body 1, and the outer walls of the two third limiting rods 641 are movably sleeved with a third spring 643, and the third spring 643 is located on the upper side of the insert block 642, and the front side of the insert block 642 is fixedly connected with a pull block 644 near the upper side, and the pull block 644 is located on the front side of the wedge body 1.

[0039] It should be noted that when the lower side of the insert block 642 is located inside the slot, the sealing plate 61 cannot be pulled out, and the pull block 644 is pushed upward so that the pull block 644 drives the insert block 642 to move upward, causing the insert block 642 to disengage from the slot. At this time, the pull block 644 can be pulled forward to pull the sealing plate 61 out of the inner side of the wedge body 1.

[0040] like Figure 2 , Figure 6 As shown, a drainage hole 65 is opened at the rear side of the placement box 62 near the bottom, and a guide plate 66 is fixedly connected to the rear side of the placement box 62 near the bottom, and the drainage hole 65 is located on the upper side of the guide plate 66, and the lower end of the guide plate 66 is located directly above the water permeable hole 5.

[0041] It should be noted that after the desiccant plate 63 absorbs water vapor, the water moves downward due to the influence of gravity, and a large amount of water accumulates at the bottom of the desiccant plate 63, causing the bottom of the desiccant plate 63 to reach a saturated state ahead of time, and the excess water is discharged from the drainage hole 65, and the guide plate 66 guides the discharged water to the water-permeable hole 5, and finally discharged from the inner side of the wedge body 1.

[0042] like Figure 1 As shown, a plurality of evenly distributed screw holes are provided on the front side of the installation frame 3 near the edge.

[0043] It should be noted that the screw holes are used to fix the installation frame 3 on the rear vertical wall, thereby fixing the whole.

[0044] The working principle of the utility model is as follows: first, the stopper 42 is located on the upper side of the enclosure 2, so that the upper side of the enclosure 2 is blocked, so that the wedge body 1 cannot drive the enclosure 2 to be pulled out from the inner side of the installation frame 3, and the push button 44 is pushed to the side away from the wedge body 1, so that the stopper 42 is separated from the upper side of the enclosure 2. At this time, the wedge body 1 can drive the enclosure 2 to be pulled out from the inner side of the installation frame 3. The shape of the stopper 42 is such that when the enclosure 2 is placed, the left and right edges of the lower side of the enclosure 2 can push the stopper 42, so that the stopper 42 enters the installation frame 3. The inner side of the left and right walls, until the enclosure 2 is completely placed inside the installation frame 3, the first spring 43 pushes the stopper 42 to return to its original position. When the stopper 42 is separated from the upper side of the enclosure 2, the second spring 453 pushes the top block 452 to move upward, and the top block 452 pushes the enclosure 2 to move upward. At this time, the side of the enclosure 2 resists the stopper 42 to prevent the stopper 42 from moving back to the upper side of the enclosure 2 when the first spring 43 pushes the stopper 42 to return to its original position. By pushing the push button 44 to the side away from the wedge body 1, the wedge body 1 is pushed out as a whole by the top block 452, causing the wedge body 1 to be pushed out ... The split body 1 can be easily removed, which is convenient for the user to remove the sharp split body 1 from the wall. It is easy to disassemble and install, which is convenient for the user to maintain it, and avoids the problem that the sound absorption holes thereon are blocked due to long-term use. At the same time, the sharp split body 1 is difficult to disassemble, resulting in a decrease in the overall sound absorption capacity. Finally, the moisture absorption plate 63 absorbs the water vapor inside the sharp split body 1, so that the inside of the sharp split body 1 remains dry. The sealing plate 61 can drive the placement box 62 to pull out the moisture absorption plate 63, which is convenient for replacing the moisture absorption plate 63. After the moisture absorption plate 63 absorbs the water vapor Affected by gravity, the moisture moves downward, and a large amount of moisture accumulates at the bottom of the moisture absorbing plate 63, causing the bottom of the moisture absorbing plate 63 to reach a saturated state in advance, and the excess moisture is discharged from the drainage hole 65, and the guide plate 66 guides the discharged water to the water-permeable hole 5, and finally discharged to the inner side of the wedge body 1, through the closed cavity formed between the wedge body 1 and the phase surface, the moisture absorbing plate 63 absorbs the water vapor retained in the cavity to prevent the water vapor from eroding the wall, and at the same time, the excess moisture is discharged from the drainage hole 65 and the water-permeable hole 5, so that the inside of the wedge body 1 is dry.
