Description

Technical Field

[0001] This utility model relates to the field of wind turbine silencers, specifically a hydrophobic silencer. Background Technology

[0002] In the wind turbine industry, silencers are commonly used. When the medium contains water, the internal sound-absorbing cotton of the silencer plate is easily soaked, which affects the noise reduction effect, makes the silencer heavier, and reduces the service life of the silencer because the internal sound-absorbing cotton deteriorates when soaked in water. Existing silencers are prone to water damage and weight increase when used with media containing moisture, and the cleanliness of the medium is also affected. Furthermore, since the silencer plate is welded into the silencer frame structure, it is impossible to efficiently remove moisture through high-temperature drying or other methods, making maintenance difficult.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0014] Please refer to 1-2. One embodiment of this utility model is provided: a hydrophobic silencer, including an outer frame 1, a side door 2 on one side of the outer frame 1, a plurality of upper top plates 3 on the upper surface of the outer frame 1, a slide rail 4 on the lower surface of the upper top plates 3 and the bottom surface of the inner surface of the outer frame 1, and a sound-absorbing plate structure 5 slidably connected on the slide rail 4. The sound-absorbing plate structure 5 is slid into the outer frame 1, which facilitates the adjustment of the number of sound-absorbing plate structures 5, and also facilitates the cleaning and replacement of the sound-absorbing plate structures 5, which is convenient for later maintenance.

[0015] The sound-absorbing sheet structure 5 includes a sound-absorbing sheet frame 51. Fiberglass cloth 52 is provided on both sides of the sound-absorbing sheet frame 51. A twill-woven wire mesh 53 is provided on the side of the fiberglass cloth 52 away from the sound-absorbing sheet frame 51. A welded wire mesh 54 is provided on the side of the twill-woven wire mesh 53. A perforated mesh plate 55 is provided on the side of the welded wire mesh 54. Drainage holes 56 are provided on the lower surface of the sound-absorbing sheet frame 51. Before water vapor enters the sound-absorbing sheet frame 51, it needs to pass through the perforated mesh plate 55 and the twill-woven wire mesh 53. Water droplets are blocked by the perforated mesh plate 55 and the twill-woven wire mesh 53, reducing the amount of water entering the interior of the sound-absorbing sheet frame 51. The welded wire mesh 54 acts as a support and isolation, preventing the twill-woven wire mesh 53 from becoming too close to the perforated mesh plate 55 and losing its function. Drainage holes are provided on the bottom surface of the sound-absorbing sheet frame 51 to drain away some of the water that has permeated the hydrophobic layer.

[0016] The sound-absorbing frame 51 is filled with sound-absorbing cotton to reduce noise. The upper and lower sides of the sound-absorbing frame 51 are provided with slide rail grooves, which correspond to the slide rail 4, so as to facilitate the installation and disassembly of the sound-absorbing structure 5.

[0017] The top plate 3 has an inverted V-shaped structure. The inverted V-shaped structure can divert water into the interior of the outer frame 1, preventing water droplets from concentrating in a sound-absorbing plate frame 51. The top plate 3 and the sound-absorbing plate structure 5 correspond one-to-one.

[0018] A hydrophobic layer is formed by twill woven wire mesh 53, welded wire mesh 54 and perforated mesh plate 55. The four sides of the inner frame 1 are equipped with hydrophobic layers. The twill woven wire mesh 53 and perforated mesh plate 55 are used to block water droplets, reduce water droplets from entering the sound-absorbing cotton, and thus extend the life of the sound-absorbing cotton.

[0019] Working principle: When air containing water droplets enters the outer frame 1, the water droplets in the air will first hit the perforated mesh plate 55, and after the first obstruction, the water droplets will be dispersed. Some of the dispersed water droplets will move downward along the perforated mesh plate 55, and some will enter between the perforated mesh plate 55 and the twill woven wire mesh 53. This part of the water droplets will be further dispersed by the twill woven wire mesh 53, so that even less water droplets will enter the sound-absorbing plate frame 51. Then, the water will move towards the drain hole 56 due to its own gravity and be discharged. The other water droplets that do not enter the sound-absorbing plate frame 51 will be discharged from the outer frame 1.
