Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a soundproof cover for a low-noise cooling tower. Background Technology

[0002] Cooling towers are widely used in numerous fields, including industrial production, commercial buildings, and civil facilities. Their function is to cool circulating water through heat exchange between air and water, ensuring the normal operation of various systems. However, during operation, cooling towers generate significant noise from fan operation, water flow impact, and equipment vibration. This noise not only pollutes the surrounding environment and interferes with the normal lives and work of nearby residents, but may also affect noise-sensitive locations such as hospitals and schools. Long-term exposure to high-noise environments can have adverse effects on human health, such as causing hearing loss, cardiovascular disease, and impaired sleep quality.

[0003] Traditional sound insulation equipment used for cooling towers often does not take into account the heat dissipation requirements of the cooling tower during operation. It may focus on sound insulation while neglecting heat dissipation, which will affect the normal operation of the cooling tower and reduce its working efficiency.

[0004] To address this issue, the present invention provides a soundproof cover for a low-noise cooling tower. By installing easily removable guide plates inside the soundproof cover, the airflow inside the cover is stably guided, forming a sound barrier on one side, thereby further enhancing the soundproofing effect of the cover and solving the aforementioned problems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-4 A soundproof cover for a low-noise cooling tower includes a soundproof cover body 1, a soundproof plate 2 fixedly connected to the upper end of the soundproof cover body 1, a ventilation mechanism 3 provided inside the soundproof cover body 1, the ventilation mechanism 3 includes an air inlet window 31 and a guide plate 33, an umbrella-shaped pin 34 fixedly connected to the bottom left side of the guide plate 33, a bolt 35 threadedly connected to the bottom right side of the guide plate 33, the bolt 35 extending into the interior of the umbrella-shaped pin 34 and threadedly connected to the umbrella-shaped pin 34, and the interior of the guide plate 33 is filled with sound-absorbing glass wool 36.

[0024] The air inlet window 31 is fixedly installed at the bottom of both sides of the soundproof cover 1, and a filter screen 32 is connected to one side of the air inlet window 31 by a hinge.

[0025] In this embodiment, by providing air inlet windows 31 on both sides of the soundproof enclosure 1, external airflow can enter the interior of the soundproof enclosure 1. Combined with the cooling tower's cooling fan, this allows hot airflow inside the soundproof enclosure 1 to be exhausted, while cold airflow enters the interior of the soundproof enclosure 1 through the air inlet windows 31, forming an air circulation and accelerating heat dissipation inside the soundproof enclosure 1. The guide plate 33, in conjunction with its placement, ensures that external airflow flows smoothly towards the air outlet 14, guaranteeing unobstructed airflow within the soundproof enclosure 1 and enhancing heat dissipation. By providing umbrella-shaped pins 34 and bolts 35 at the bottom of the guide plate 33, it can be inserted into the soundproof enclosure 1. During installation of the guide plate 33, the umbrella-shaped pins 34 are aligned with a pre-set... The hole at the installation location inside the soundproof cover 1 is inserted, and the bolt 35 is rotated to allow the bolt 35 to enter the interior of the umbrella-shaped pin 34. The umbrella-shaped part of the umbrella-shaped pin 34 is pushed open from the inside to the outside, so that the umbrella-shaped part firmly abuts against the inner wall of the hole, thereby enhancing the fixing effect between the guide plate 33 and the soundproof cover 1. When disassembling the guide plate 33, simply rotate the bolt 35 in the opposite direction to release the fixing between the guide plate 33 and the soundproof cover 1. By setting sound-absorbing glass wool 36 inside the guide plate 33, a sound-absorbing barrier can be formed inside the soundproof cover 1, enhancing the sound insulation effect of the soundproof cover 1. By setting a filter screen 32 on the surface of the air inlet window 31, it is possible to prevent debris from entering the interior of the soundproof cover 1.

[0026] Example 2:

[0027] Please see Figure 2-5 This embodiment provides a technical solution based on embodiment one: the bottom front side of the soundproof cover 1 is connected to an inspection door 11 via a hinge, and the interior of the soundproof cover 1 is fixedly connected to the two sides of the cooling tower with mounting columns 12.

[0028] The surface of the mounting column 12 is evenly provided with insertion holes 13. The inner diameter of the insertion hole 13 matches the outer diameter of the umbrella-shaped pin 34. The guide plate 33 is inserted into the mounting column 12 through the insertion hole 13.

[0029] The top of the soundproof cover 1 has an air outlet 14, and the inside of the air outlet 14 is equipped with a grid-type silencer 15 that is fixedly connected to the soundproof cover 1. The top of the air outlet 14 is equipped with a rainproof canopy 16 that is fixedly connected to the soundproof cover 1.

[0030] The inner bottom layer of the sound insulation board 2 is fixedly connected with sound-absorbing cotton 21, the inner middle layer of the sound insulation board 2 is fixedly connected with butyl rubber layer 22, and the outermost layer of the sound insulation board 2 is fixedly connected with high-density fiberboard 23.

[0031] In this embodiment, by providing mounting columns 12 inside the soundproof enclosure 1 and providing insertion holes 13 on the surface of the mounting columns 12, the installation and disassembly of the guide plate 33 and the soundproof enclosure 1 are facilitated. By providing an air outlet 14 at the top of the soundproof enclosure 1, the hot air inside the soundproof enclosure 1 is easily discharged, enhancing the heat dissipation effect of the soundproof enclosure 1. By providing a grille-type silencer 15 inside the air outlet 14, and filling the inside of the grille-type silencer 15 with sound-absorbing cotton, the noise escaping through the air outlet 14 can be absorbed, further enhancing the sound insulation effect. By installing a rainproof canopy 16 at the top of the air outlet 14, rainwater can be prevented from entering the interior of the soundproof cover 1. By covering the surface of the soundproof cover 1 with soundproof panels 2, the noise emitted by the cooling tower can be effectively insulated. Sound-absorbing cotton 21 is installed on the innermost side of the soundproof panel 2, which can effectively absorb mid-to-high frequency noise. By installing a butyl rubber layer 22 in the middle layer of the soundproof panel 2, vibration can be suppressed and the propagation of low-frequency noise can be reduced. By installing a high-density fiberboard 23 on the outermost layer of the soundproof panel 2, sound penetration can be further blocked. These three layers work together to form an effective barrier against broadband noise.
