Description

Technical Field

[0001] This utility model relates to the field of generator fairing technology, specifically a foldable noise-absorbing fairing. Background Technology

[0002] Generator sets generate high-temperature flue gas during operation, which needs to be efficiently discharged through a deflector. The deflector adopts a corrugated pipe structure, giving it excellent flexibility, extensibility, compensation capability, sealing performance, pressure resistance, and corrosion resistance, making it irreplaceable in terms of installation adaptability. Existing patent application number: CN202121813088.0 A novel high-temperature resistant corrugated pipe includes a corrugated pipe body and a corrugated pipe inner groove. The corrugated pipe body has an inner groove that extends through one side. A high-temperature resistant layer is provided inside the corrugated pipe body to improve the high-temperature resistance of the corrugated pipe body. An anti-fracture layer is provided inside the corrugated pipe body and inside the high-temperature resistant layer to prevent the corrugated pipe body from breaking.

[0003] The aforementioned patent describes a corrugated pipe structure. The corrugated pipe can be freely bent by stretching and folding, which greatly improves the installation adaptability. However, in the prior art, there are no additional reinforcement measures for the bent part of the corrugated pipe. When the internal airflow passes through the bend, it is easy to cause vibration and generate noise, which is not conducive to noise control. Therefore, we propose a foldable sound-absorbing guide hood to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a foldable noise-absorbing hood to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable noise-absorbing hood, comprising a hood and a reinforcing structure, wherein the reinforcing structure is fitted on the outer surface of the hood, and the reinforcing structure comprises an upper hoop, a lower hoop, a support rod and an elastic clamping mechanism, wherein the upper hoop and the lower hoop are respectively fitted and installed on the upper and lower sides of the outer surface of the hood, wherein the outer edges of the upper hoop and the lower hoop are connected by the support rod, and an elastic clamping mechanism is provided on the inner side of the upper hoop.

[0006] Preferably, the support rod adopts a gooseneck tube structure.

[0007] Preferably, the number of support rods is not less than three, and all support rods are equidistantly arranged around the outer edge of the upper hoop.

[0008] Preferably, the elastic clamping mechanism includes a clamp and an elastic folding member. The clamp is located at the inner edge of the upper hoop, and the elastic folding member is bonded to both ends of the clamp. The elastic folding member is bonded and fixed to the inner wall of the upper hoop, so that the clamp and the upper hoop are elastically connected. The upper hoop is elastically clamped to the outside of the guide shield by the clamp.

[0009] Preferably, the upper and lower hoops have the same size and specifications, and both the upper and lower hoops are provided with elastic clamping mechanisms inside.

[0010] Preferably, a screw is connected to the bottom end of the support rod, and a nut is rotatably installed on the outer edge of the lower hoop. The nut is threaded onto the surface of the support rod, so that the lower hoop and the support rod are threaded together.

[0011] Preferably, mounting plates are welded to both the outer sides of the upper and lower hoop rings.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a reinforcing structure on the outer surface of the fairing. The installation is completed by attaching the upper and lower hoops to both ends of the fairing's bend and adjusting the support rod to the corresponding bending angle. The support rod provides external support for the fairing's bend, improving the stability of the bend and preventing the airflow from swaying or resonating when passing through it, thus effectively controlling noise.

[0013] This utility model features a screw at the bottom of the support rod. When adjusting the spacing, the screw is moved by turning the nut, thereby adjusting the installation spacing between the upper and lower hoops to better fit the reinforcement structure with the fairing.

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1 This utility model provides a foldable noise-absorbing fairing, including a fairing 1 and a reinforcing structure 2. The reinforcing structure 2 is fitted on the outer surface of the fairing 1. The reinforcing structure 2 includes an upper hoop 21, a lower hoop 22, a support rod 23 and an elastic clamping mechanism 24. The upper hoop 21 and the lower hoop 22 are respectively fitted and installed on the upper and lower sides of the outer surface of the fairing 1. The outer edges of the upper hoop 21 and the lower hoop 22 are connected by the support rod 23. The elastic clamping mechanism 24 is provided on the inner side of the upper hoop 21.

[0018] To further explain, the support rod 23 adopts a gooseneck tube structure. The gooseneck tube can bend freely and be shaped for support, and is flexible in adjustment. This allows the support rod 23 to bend synchronously with the fairing 1 and provide external support for it without affecting the adjustment flexibility of the fairing 1. The number of support rods 23 is not less than 3. All support rods 23 are equidistantly arranged around the outer edge of the upper hoop 21 to ensure the support firmness in all directions.

[0019] Specifically, the fairing 1 can be freely bent by telescopic folding, but the internal airflow is prone to vibration and noise when passing through the bend. By setting a reinforcement structure 2 on the outer surface of the fairing 1, the upper hoop 21 and the lower hoop 22 are first fitted and installed on both ends of the bend of the fairing 1, and the support rod 23 is adjusted to the corresponding bending angle to complete the installation. The support rod 23 provides external support for the bend of the fairing 1, improves the support stability of the bend, and makes it less likely for the airflow to shake and resonate when passing through the bend, thereby effectively controlling noise.

[0020] Please see Figure 2-4 This utility model provides a foldable noise-absorbing guide hood. The elastic clamping mechanism 24 includes a clamp 241 and an elastic folding member 242. The clamp 241 is located at the inner edge of the upper hoop 21. The elastic folding member 242 is bonded to both ends of the clamp 241. The elastic folding member 242 is bonded and fixed to the inner wall of the upper hoop 21, so that the clamp 241 and the upper hoop 21 are elastically connected. The upper hoop 21 is elastically clamped to the outside of the guide hood 1 by the clamp 241, so as to better adapt to the sleeve installation of pipes of different diameters.

[0021] To further explain, the upper hoop 21 and the lower hoop 22 have the same size and specifications, and both the upper hoop 21 and the lower hoop 22 are equipped with an elastic clamping mechanism 24 inside.

[0022] Among them, mounting plates 27 are welded on both sides of the upper hoop 21 and the lower hoop 22. The upper hoop 21 and the lower hoop 22 can establish a support structure with the wall through the mounting plates 27, providing a more stable support for the fairing 1.

[0023] Please see Figure 5 This utility model provides a folding noise-absorbing guide cover. A screw 25 is connected to the bottom end of the support rod 23, and a nut 26 is rotatably installed on the outer edge of the lower hoop 22. The nut 26 is threadedly sleeved on the surface of the support rod 23, so that the lower hoop 22 and the support rod 23 are threadedly connected.

[0024] Specifically, when adjusting the spacing, the screw 25 is moved by turning the nut 26, thereby adjusting the installation spacing between the upper hoop 21 and the lower hoop 22, so as to better install and adapt the reinforcing structure 2 and the guide shield 1.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
