Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction equipment, in particular to a noise reduction device with a high-temperature fusing function. Background Art

[0002] Common technical measures used in noise control projects include sound absorption, sound insulation, noise reduction, and vibration reduction. The corresponding equipment includes sound absorbers, sound insulation panels, silencers, and vibration dampers. An acoustic system consists of a sound source, a sound propagation path, and a receiver. Sound originates from the sound source and reaches the receiver's ears through a specific transmission medium or path. Noise control measures can be implemented at three levels: the source, the propagation path, and the receiver. A soundproof enclosure is a commonly used technical measure in noise control projects to control noise within the propagation path. Its primary function is to place noise-generating equipment within the enclosure and, using noise reduction products such as sound insulation panels, soundproof doors and windows, and silencers, reduce the transmission of equipment noise outside the enclosure, thereby reducing environmental noise.

[0003] In noise control projects, soundproof enclosures are often used for noise control of various equipment. In order to obtain better sound insulation performance, the sound insulation panels are usually firmly connected to the structure, well sealed, and have certain rainproof and heat insulation functions.

[0004] However, when a fire occurs in the equipment inside the soundproof enclosure, due to the presence of the soundproof enclosure, the fire-fighting facilities cannot directly and effectively extinguish the fire source, which increases the difficulty of controlling the fire. The equipment inside the enclosure is difficult to rescue in time, resulting in serious damage to the equipment and huge economic losses. Utility Model Content

[0005] In view of the above problems, the present invention provides a noise reduction device with a high-temperature fusing function.

[0006] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is as follows:

[0007] Provided is a noise reduction device with a high-temperature fusing function, comprising a sound insulation enclosure, a frame, and a sound absorbing and insulating plate. The frame is disposed on an end of the sound insulation enclosure away from a sound source. Both ends of the sound absorbing and insulating plate are connected to an eccentric rotating shaft. The sound absorbing and insulating plate is rotatably connected to the frame via the eccentric rotating shaft. A fastener for limiting the rotation of the sound absorbing and insulating plate is disposed within the frame on a side of the sound absorbing and insulating plate close to the sound insulation enclosure. The fastener is used to limit the sound absorbing and insulating plate in a closed frame state. The melting point of the fastener is lower than that of the frame, the sound absorbing and insulating plate, and the eccentric rotating shaft.

[0008] Furthermore, the fastener is made of plastic or nylon material.

[0009] Furthermore, a first sealing fin and a second sealing fin are provided at the edge of the sound absorbing and insulating plate. The first sealing fin is provided on the heavier sound absorbing and insulating plate on the side of the eccentric rotating shaft, and is used to abut against the inner wall of the frame. The second sealing fin is provided on the lighter sound absorbing and insulating plate on the side of the eccentric rotating shaft, and is used to abut against the outer wall of the frame.

[0010] Furthermore, the fastener includes a fastening bolt and a fastening nut, and the fastening bolt passes through the frame and the first sealing fin plate and is threadedly connected to the fastening nut.

[0011] Furthermore, sealing gaskets are provided on the surfaces of the first sealing fin and the second sealing fin for contacting the frame.

[0012] Further, the frame is arranged horizontally.

[0013] Furthermore, a plurality of installation channels are arranged in an array on the frame, and a sound absorbing and insulating panel is provided in each installation channel.

[0014] The beneficial effects of the present invention are as follows: when a fire occurs in the soundproof enclosure, the fasteners used to fix the frame and the sound-absorbing and insulating panels will be damaged under high temperature conditions, and only the eccentric shaft will remain to connect the frame and the sound-absorbing and insulating panels. Since the eccentric shaft is eccentrically arranged, the heavier side of the sound-absorbing and insulating panels rotates downward under the action of gravity, thereby automatically opening the top of the soundproof enclosure and preventing damage to the equipment inside the enclosure due to falling. At this time, the fire extinguishing agent can enter the interior of the soundproof enclosure from the top of the soundproof enclosure to extinguish the fire, thereby controlling the fire in the early stages and reducing losses.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] The embodiment of the present application discloses a noise reduction device with a high-temperature fusing function, referring to Figure 1 、 Figure 2 and Figure 3 , comprising a soundproof enclosure 1, a frame 2, and sound-absorbing and insulating panels 3. The soundproof enclosure 1 is installed vertically, and a vertical channel is provided inside the soundproof enclosure 1. The frame 2 is installed horizontally at the end of the soundproof enclosure 1 away from the sound source. A plurality of mounting channels 21 are arranged in an array on the frame 2, and a sound-absorbing and insulating panel 3 is provided in each mounting channel 21.

[0023] An eccentric shaft 4 is integrally fixedly connected to each end of the sound-absorbing and insulating panel 3. The eccentric shafts 4 are coaxially connected, with their axes parallel to and offset from the centerline of the panel 3. The eccentric shafts 4 are rotatably connected to the inner wall of the mounting channel 21 on the frame 2. As the sound-absorbing and insulating panel 3 rotates, it seals the mounting channel 21, providing sound insulation and noise reduction.

[0024] A fastener 5 is provided within the frame 2 to secure the sound-absorbing and insulating panel 3 in the closed frame 2 state. This fastener 5 is located on the side of the panel 3 closest to the soundproof enclosure 1, restricting its rotation. The fastener 5 is made of a high-temperature fusible material, with a melting point lower than that of the frame 2, the panel 3, and the eccentric shaft 4. If a fire breaks out at the source, the high temperature will melt the fastener 5 within the soundproof enclosure 1. Once melted, gravity will cause the heavier end of the panel 3, located on the eccentric shaft 4, to rotate downward, opening the mounting channel 21. This allows fire extinguishing agents to enter the enclosure 1 from the top and directly impact the fire source. This allows for rapid fire control and minimized damage in the event of a fire.

[0025] Reference Figure 4 and Figure 5The sound-absorbing and insulating panel 3 has a sound-isolating function. The gap between the panel 3 and the mounting channel 21 reduces the sound insulation of the device. Therefore, a first sealing fin 6 and a second sealing fin 7 are provided along the circumference of the edge of the sound-absorbing and insulating panel 3. The first sealing fin 6 is positioned on the heavier side of the sound-absorbing and insulating panel 3 on the eccentric rotating shaft 4. When the sound-absorbing and insulating panel 3 closes the mounting channel 21, the first sealing fin 6 abuts the inner wall of the frame 2. The second sealing fin 7 is positioned on the lighter side of the sound-absorbing and insulating panel 3 on the eccentric rotating shaft 4. When the sound-absorbing and insulating panel 3 closes the mounting channel 21, the second sealing fin 7 abuts the outer wall of the frame 2. With this arrangement, when the sound-absorbing and insulating panel 3 rotates, the first sealing fin 6 and the second sealing fin 7 can smoothly rotate with the panel 3 to close the mounting channel 21, sealing the gap between the panel 3 and the mounting channel 21.

[0026] In the embodiment of the present application, fastener 5 comprises a fastening bolt and a fastening nut. The fastening bolt passes through the frame 2 and the first sealing fin 6 and is then threadedly connected to the fastening nut. In other embodiments, fastener 5 may also be a pin and a buckle. The pin passes through the frame 2 and the first sealing fin 6 and is then buckled and connected to the buckle. Fastener 5 can be made of plastic or nylon, which has a low melting point. If a fire occurs at the sound source, the flames will burn and melt fastener 5.

[0027] Furthermore, a sealing gasket 8 is provided on each of the first sealing fin 6 and the second sealing fin 7 on one side thereof that is in contact with the frame 2. When the sound absorbing and insulating panel 3 closes the installation passage 21, the sealing gaskets 8 on the first sealing fin 6 and the second sealing fin 7 are in sealing contact with the frame 2, thereby improving the sealing between the sound absorbing and insulating panel 3 and the installation frame.

Therefore, the appended claims are intended to be interpreted as encompassing the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Clearly, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
