[0002] Construction engineering refers to the process of building, renovating, and expanding buildings, structures, and ancillary facilities in accordance with design drawings and relevant technical specifications through a series of technical means and construction procedures. It covers multiple stages such as earthwork excavation, infrastructure, main structure construction, and decoration. The operation of various large-scale machinery and equipment, as well as the processing and installation of components, will generate a large amount of continuous and high-intensity noise. This noise will not only seriously interfere with the daily life and rest of residents around the construction site and affect their physical and mental health, but also fail to meet the requirements of environmental protection laws and regulations on regional environmental noise limits. Therefore, noise reduction devices must be used in construction engineering to control noise propagation and reduce the impact of noise on the surrounding environment.
[0003] Currently, noise reduction devices commonly used in construction projects mainly achieve noise reduction by setting up sound barriers, installing sound-absorbing materials, or using noise reduction covers. However, when used in harsh environments such as sun exposure and rain, these devices can be damaged, affecting the smoothness of construction. Utility Model Content

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a noise reduction device for construction engineering, including a handle 1, a threaded rod 2 fixedly connected inside the handle 1, a limit bracket 3 rotatably connected to the outer wall of the threaded rod 2, a slide rail 4 fixedly connected to the outer wall of the limit bracket 3, a slider 5 slidably connected inside the slide rail 4, a fixed bracket 6 fixedly connected to the outer wall of the slider 5, a sunshade cloth 7 fixedly connected inside the fixed bracket 6, a slider 8 fixedly connected to the outer wall of the fixed bracket 6, a fixed block 9 fixedly connected to the outer wall of the slide rail 4, and a support component fixedly connected to the outer wall of the fixed block 9, the support component being used to support the fixed block 9; Specifically, rotating the handle 1 causes the threaded rod 2 to rotate. The limiting bracket 3 supports and restricts the threaded rod 2, ensuring that its position remains unchanged and it can only rotate on its own axis when rotated by the handle 1. This, in turn, moves the slider 8 along the outer wall of the threaded rod 2. Consequently, the slider 5 and the fixed bracket 6 move linearly along the inner and outer walls of the slide rail 4, respectively. Simultaneously, the slider 8 and the fixed bracket 6 are fixed together and constrained by the slide rail 4, ensuring that the slider 8 always moves linearly when rotated by the threaded rod 2 and does not undergo any changes in position. As the sunshade cloth 7 rotates, it is stretched or contracted by the linear motion of the fixed bracket 6. During operation, the limiting bracket 3, the slide rail 4, and the noise reduction plate 11 ensure that the sunshade cloth 7 is always below the threaded rod 2 and never touches it, so that the sunshade cloth 7 will not get stuck when it stretches or contracts. At the same time, the support component supports the fixed block 9, ensuring that the positions of the limiting bracket 3 and the slide rail 4 do not change. This achieves the effect of preventing the equipment from overheating and being damaged when the temperature is too high, and reducing the interference of rainwater on the progress of the project when it rains, thus achieving the effects of reducing temperature and improving work efficiency.
[0019] Reference Figure 1 and Figure 2 The support assembly includes a second fixed bracket 10, the outer wall of the first fixed block 9 is fixedly connected to the second fixed bracket 10, and the outer wall of the second fixed bracket 10 is fixedly connected to a noise reduction plate 11. Specifically, after the construction equipment is protected from the sun or rain, the fixing block is fixed and supported by the fixing bracket 2 10 to ensure that the limiting bracket 3 and the slide rail 4 will not fall off the outer wall of the noise reduction plate 11 during operation, so that the device will not collapse during operation and cause injury to personnel, thereby improving work safety and the stability of the operation order.
[0020] Reference Figure 1 and Figure 2 The outer wall of the fixed bracket 6 is fixedly connected to the outer wall of the limiting bracket 3, and the internal thread of the slider 8 is connected to the outer wall of the threaded rod 2. Specifically, by fixing the fixed bracket 6 with the limiting bracket 3, the fixed bracket 6 connected to the limiting bracket 3 is prevented from detaching as a whole when the sunshade cloth 7 moves. During operation, the threaded rod 2 and the fixed bracket 6 are always restricted to slide on the outer wall of the slide rail 4, thereby ensuring that the slider 5 always performs linear motion.
[0021] Reference Figure 1 and Figure 2 The outer wall of the slide rail 4 is fixedly connected to the outer wall of the noise reduction plate 11, and the outer wall of the fixed bracket 6 is slidably connected to the outer wall of the slide rail 4. Specifically, the sunscreen cloth 7 is supported by the noise reduction plate 11 and the slide rail 4, ensuring that it always extends or retracts in the middle section between the limiting bracket 3 and the noise reduction plate 11. At the same time, it is restricted by the slide rail 4, so that the sunscreen cloth 7 inside the fixed bracket 6 will not flip or fall off when it extends or retracts.
[0022] Reference Figure 1 and Figure 2 The outer wall of the threaded rod 2 is rotatably connected to the inside of the noise reduction plate 11; Specifically, the support of the noise reduction plate 11 and the limiting bracket 3 ensures that the position of the threaded rod 2 does not change during rotation, thus driving the slider 8 to move in a straight line.
[0023] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The noise reduction plate 11 is internally connected to a threaded rod 13, the outer wall of the threaded rod 13 is fixedly connected to a handle 12, the outer wall of the threaded rod 13 is rotatably connected to a limit block 15, the outer wall of the threaded rod 13 is threadedly connected to a slider 14, the inner wall of the slider 14 is fixedly connected to a fixing post 16, the outer wall of the fixing post 16 is rotatably connected to a rotating bracket 17, the inner wall of the rotating bracket 17 is rotatably connected to a fixing post 19, the outer wall of the fixing post 16 is rotatably connected to a rotating bracket 18, the outer wall of the fixing post 19 is rotatably connected to a fixing block 20, and the outer wall of the fixing block 20 is fixedly connected to a perforated aluminum plate 21. Specifically, rotating handle 12 causes threaded rod 13 to rotate. Noise-reducing plate 11 supports and restricts threaded rod 13, ensuring that its position remains unchanged and it can only rotate on its own axis when rotated by handle 12. This, in turn, moves slider 14. Limiting block 15 prevents sliders 14 on both sides of threaded rod 13 from colliding and being damaged. Simultaneously, the force generated by the movement of slider 14 causes rotating bracket 17 and rotating bracket 28 to rotate to both sides around the axis of fixed column 16. The restriction of the fixed column 16 ensures that the positions of the rotating bracket 17 and the rotating bracket 28 do not change when they are flipped. This causes the rotating bracket 17 and the rotating bracket 28 to flip on the fixed column 29, and the force generated is converted into pushing or dragging the perforated aluminum plate 21 on the outer wall of the fixed block 20. The spacing between the perforated aluminum plates 21 on both sides can be adjusted according to the frequency of the noise, thereby adjusting the cavity resonance frequency and achieving noise reduction. Moreover, there is no need to replace the fixed cavity sound insulation board for different noise scenarios, thus achieving the effect of improving noise reduction performance and reducing costs.
[0024] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 Handle 2 12 is rotatably connected to the outer wall of noise reduction plate 11, and the outer wall of rotating bracket 2 18 is rotatably connected to the outer wall of rotating bracket 1 17. Specifically, the noise reduction plate 11 restricts and supports the handle 12 to prevent the position of the handle 12 from changing when the threaded rod 13 rotates. At the same time, the rotating bracket 17 and the rotating bracket 28 flip on the outer wall of the fixed column 16, ensuring that the rotating bracket 17 and the rotating bracket 28 flip in opposite directions when the slider 3 14 moves, thereby pushing the perforated aluminum plates 21 on both sides to move, thus achieving the effect of adjusting the cavity frequency.
[0025] Reference Figure 4 , Figure 5 and Figure 6 The outer wall of the perforated aluminum plate 21 is slidably connected to the inside of the noise reduction plate 11, and the inside of the rotating bracket 2 18 is rotatably connected to the outer wall of the fixed column 2 19. Specifically, the noise reduction plate 11 restricts and supports the perforated aluminum plate 21. The slider 3 14 drives the noise reduction plate 11 to move to both sides. At the same time, it is restricted by the sliding of the noise reduction plate 11 inside the perforated aluminum plate 21, ensuring that the slider 3 14 always makes linear motion. Meanwhile, the rotating bracket 1 17 and the rotating bracket 2 18 rotate on the outer wall of the fixed column 2 19, making the pushing or dragging of the perforated aluminum plate 21 more stable when sliding inside the noise reduction plate 11.
[0026] Working principle: When the device is needed, the noise reduction plate 11 is first placed on one side of the construction equipment. Then, by turning the handle 1, the threaded rod 2 is rotated inside the limiting bracket 3 and the noise reduction plate 11. As the threaded rod 2 rotates, the slider 8 moves. At the same time, the slider 8 and the fixed bracket 6 slide on the slide rail 4. When the fixed bracket 6 moves, it causes the sunshade cloth 7 to extend or retract. When the temperature is too high, it prevents the equipment from overheating and being damaged. When it rains, it reduces the rainwater from interfering with the progress of the project, thus achieving the effects of reducing temperature and improving work efficiency. After the noise reduction plate 11 is placed, the handle 12 drives the threaded rod 13 to rotate within the limit block 15, thereby moving the slider 14. This causes the rotating bracket 17 and rotating bracket 28 to rotate to both sides around the axis of the fixed column 16. The rotating bracket 17 and rotating bracket 28 then push or drag the perforated aluminum plate 21 fixed by the fixed block 20 to move inside the noise reduction plate 11. This allows for the adjustment of the cavity resonance frequency when the noise frequency is too high or too low, achieving a more stable and comprehensive noise reduction effect. Furthermore, it eliminates the need to purchase multiple specifications of fixed cavity sound insulation panels for different noise scenarios, thus improving noise reduction performance and reducing costs. This device not only prevents equipment from overheating and being damaged when the temperature is too high, but also reduces the impact of rain on the project progress when it rains. It can also lower the temperature and improve work efficiency. At the same time, it can adjust the cavity resonance frequency when the noise frequency is too high or too low, achieving a more stable and comprehensive noise reduction effect. It also eliminates the need to purchase fixed cavity sound insulation panels of different specifications for different noise scenarios, thus improving noise reduction performance and reducing costs.
