Description

Technical Field

[0001] This application relates to the field of sound insulation and noise reduction walls, and more specifically, to an air-source sound insulation and noise reduction device. Background Technology

[0002] Generally, soundproof walls are installed on the side of noisy roads such as railways, highways, and urban expressways near schools and residential areas to reduce the transmission of airborne noise. However, the soundproof walls used in these cases are often thin and are installed as a whole without any airtightness. In strong winds, these walls are often blown down or damaged, which reduces their lifespan. Utility Model Content

[0003] To overcome the above shortcomings, this application provides an air-source sound insulation and noise reduction device, which aims to improve the problem that sound insulation and noise reduction walls are often blown down or damaged by strong winds in windy weather, thus reducing the service life of the sound insulation and noise reduction walls.

[0004] This application provides an air source sound insulation and noise reduction device, including a fixed frame and a sound insulation component. The sound insulation component includes a first lifting plate, a second lifting plate, a connecting frame, a rotating frame, a connecting rod, and a blade. The first lifting plate and the second lifting plate are both provided with through holes spaced apart. The first lifting plate and the second lifting plate are slidably fitted together. The first lifting plate and the second lifting plate are both disposed inside the fixed frame. The connecting rods are symmetrically arranged. The connecting frame is fixedly inserted into the upper part of the fixed frame. The rotating frame is rotatably connected to the middle part of the connecting frame. One side of the rotating frame is slidably connected to one of the connecting rods, and the other side of the rotating frame is slidably connected to another connecting rod. One end of one connecting rod is rotatably connected to the first lifting plate, and one end of the other connecting rod is rotatably connected to the second lifting plate. The blade is fixedly connected to the rotating frame.

[0005] In one specific implementation, the fixing frame includes a base frame and a vertical frame, and multiple vertical frames are provided, with a first lifting plate and a second lifting plate inserted between two adjacent vertical frames.

[0006] In one specific implementation, the vertical frame is provided with a sliding groove, and both the first lifting plate and the second lifting plate are provided with pulleys, and there are multiple pulleys, which move inside the sliding groove.

[0007] In one specific implementation, both the first lifting plate and the second lifting plate are made of sound-insulating material.

[0008] In one specific implementation, a refractive plate is provided on one side of the first lifting plate, and multiple refractive plates are spaced apart.

[0009] In one specific implementation, the connecting frame includes a insert and a crossbar. The inserts are symmetrically arranged at both ends of the crossbar, and the inserts are inserted into the upper part of the vertical frame. The inserts are fixedly connected to the crossbar, and the rotating frame is rotatably connected to the crossbar.

[0010] In one specific implementation, the rotating frame is symmetrically provided with shift forks, and one end of each shift fork is provided with a round rod that passes through the interior of the connecting rod.

[0011] In one specific implementation, the connecting rod has a through groove, and the round rod is located inside the through groove.

[0012] Beneficial Effects: This application provides an air-source sound insulation and noise reduction device. During use, the first and second lifting plates are inserted into the inner side of the fixed frame, and the connecting frame is inserted into the upper part of the fixed frame. The rotating frame and the connecting frame are rotatably connected, and the blade is fixedly connected to the upper part of the rotating frame. When the crosswind is small, the weight of the first and second lifting plates will pull the connecting rod, preventing the blade from tilting. However, when the crosswind is strong, the blade will be blown over, i.e., tilted, when the crosswind blows to one side. At this time, the blade drives the rotating frame to rotate, and the rotating frame will... Lifting one connecting rod causes either the first or second lifting plate to rise, as one connecting rod is rotatably connected to the first lifting plate and the other to the second lifting plate. As the first or second lifting plate rises, the through holes in them gradually overlap, allowing crosswinds to pass through. This reduces the impact of crosswinds on the first and second lifting plates, minimizing the risk of the soundproof wall being blown down or damaged by strong winds, and extending the lifespan of the soundproof wall.

Detailed Implementation

[0020] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0021] Please see Figure 1 This application provides an air source sound insulation and noise reduction device, including a mounting frame 100 and a sound insulation component 200.

[0022] Please see Figures 1-5 The sound insulation component 200 includes a first lifting plate 210, a second lifting plate 220, a connecting frame 230, a rotating frame 240, a connecting rod 250, and a blade 260. The first lifting plate 210 and the second lifting plate 220 are both provided with through holes 211 spaced apart. The first lifting plate 210 and the second lifting plate 220 are slidably fitted together. The first lifting plate 210 and the second lifting plate 220 are both located inside the fixed frame 100. The connecting rods 250 are symmetrically arranged. The connecting frame 230 is fixedly inserted into the upper part of the fixed frame 100. The rotating frame 240 rotates relative to the middle of the connecting frame 230. The rotating frame 240 is slidably connected to a connecting rod 250 on one side and to another connecting rod 250 on the other side. One end of the connecting rod 250 is rotatably connected to the first lifting plate 210, and one end of the other connecting rod 250 is rotatably connected to the second lifting plate 220. The blade plate 260 is fixedly connected to the rotating frame 240. The fixed frame 100 includes a base frame 110 and a vertical frame 120. Multiple vertical frame bodies 120 are provided. A first lifting plate 210 and a second lifting plate 220 are inserted between two adjacent vertical frame bodies 120.

[0023] The vertical frame 120 has a sliding groove 121. Both the first lifting plate 210 and the second lifting plate 220 are equipped with pulleys 212, and multiple pulleys 212 are provided. The pulleys 212 move within the sliding groove 121. Both the first lifting plate 210 and the second lifting plate 220 are made of sound-insulating material. A refraction plate 213 is provided on one side of the first lifting plate 210, and multiple refraction plates 213 are spaced apart. The connecting frame 230 includes a bracket 231 and a crossbar 23. 2. Insert brackets 231 are symmetrically arranged at both ends of the horizontal bar 232. Insert brackets 231 are inserted into the upper part of the vertical frame 120. Insert brackets 231 are fixedly connected to the horizontal bar 232. Rotating frame 240 is rotatably connected to the horizontal bar 232. Rotating frame 240 is symmetrically arranged with forks 241. One end of fork 241 is provided with a round rod 242. The round rod 242 passes through the interior of connecting rod 250. Connecting rod 250 has a through groove 251. The round rod 242 is located inside the through groove 251.

[0024] The working principle of this air source sound insulation and noise reduction device is as follows: During use, the first lifting plate 210 and the second lifting plate 220 are inserted between two adjacent vertical frames 120, and the connecting frame 230 is inserted into the upper part of the vertical frame 120. The rotating frame 240 is rotatably connected to the connecting frame 230, and the blade 260 is fixedly connected to the upper part of the rotating frame 240. When the crosswind is small, when it blows on one side of the blade 260, the weight of the first lifting plate 210 and the second lifting plate 220 will pull the connecting rod 250, so that the blade 260 will not tilt. However, when the crosswind is strong, when it blows on one side of the blade 260, it will blow the blade 260 over, that is, tilt it. At this time, the blade 260 drives the rotating frame 240 to rotate. The lifting of rod 40 will cause one connecting rod 250 to rise. Since one connecting rod 250 is rotatably connected to the first lifting plate 210 and the other connecting rod 250 is rotatably connected to the second lifting plate 220, when one connecting rod 250 rises, it will inevitably cause either the first lifting plate 210 or the second lifting plate 220 to rise. After the first lifting plate 210 or the second lifting plate 220 rises, the through holes 211 opened in the first lifting plate 210 and the second lifting plate 220 will gradually overlap. Therefore, crosswinds can blow through the through holes 211, reducing the impact of crosswinds on the first lifting plate 210 and the second lifting plate 220, reducing the occurrence of sound insulation and noise reduction walls being blown down or damaged by strong winds, and improving the service life of the sound insulation and noise reduction walls.
