However, as noise reduction devices used outdoors, it is difficult to avoid damage to the polyester fiberboard from external forces. Furthermore, prolonged exposure to sunlight will increase the internal temperature of the polyester fiberboard, reducing its service life and significantly decreasing the durability of the noise reduction device. Therefore, this application proposes a noise reduction device for polyester fiberboard that can improve the service life of the polyester fiberboard. Utility Model Content

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] Example
[0030] like Figure 1 and Figure 2 As shown, this utility model proposes a polyester fiberboard noise reduction device, including a support plate 1. Two support plates 2 are bolted to the top of the support plate 1, and pressure plates 3 are bolted to the top of the two support plates 2. The support plate 1, support plates 2, and pressure plates 3 are assembled into a support frame. Two perforated sound-absorbing panels 4 and two polyester fiberboards 6 are inserted between the two support plates 2. The two polyester fiberboards 6 are positioned between the two perforated sound-absorbing panels 4, and the polyester fiberboards 6 are tightly fitted to the matching perforated sound-absorbing panels 4, thus... The polyester fiber board 6 can be stably installed in the enclosed space formed by the support frame and the porous sound-absorbing board 4, which improves the protection of the polyester fiber board 6 and prevents it from being damaged by external forces. A water collection area 5 is provided between the two polyester fiber boards 6. The water collection area 5 is located inside the support frame. Rainwater can be collected and stored through the water collection area 5. The rainwater in this area can not only block the transmission of noise and improve the noise reduction effect, but also cool down the polyester fiber board 6 in hot weather and improve the service life of the polyester fiber board 6.
[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in order to improve the stability of the polyester fiberboard 6 after installation, two slots 21 are chiseled on the inner side wall of the support plate 2. The ends of the porous sound-absorbing board 4 and the polyester fiberboard 6, which are attached as a whole, are inserted into the matching slots 21 and tightly locked with them. At this time, the bottom of the polyester fiberboard 6 is covered by the support plate 1 and the top of the polyester fiberboard 6 is covered by the pressure plate 3, ensuring that the polyester fiberboard 6 can be stably installed inside the support frame, effectively improving its stability after installation.
[0032] Furthermore, to prevent rainwater in the water collection area 5 from soaking the polyester fiberboard 6, a waterproof membrane 7 is attached to the side of the polyester fiberboard 6 closest to the water collection area 5. The waterproof membrane 7 prevents the polyester fiberboard 6 from directly contacting the rainwater in the water collection area 5, avoiding prolonged immersion in water and effectively reducing the chance of damage to the polyester fiberboard 6. To prevent water leakage in the water collection area 5, waterproof adhesive is applied to the parts where the waterproof membrane 7 contacts the slot 21 for fixation, and waterproof adhesive is also applied to the parts where the waterproof membrane 7 contacts the first board 11 and the second board 31 for fixation, effectively preventing water leakage in the water collection area 5.
[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in order to facilitate the collection of rainwater in the water collection zone 5, a water collection trough 32 is carved on the top of the pressure plate 3. Several drainage holes 33 are carved at the bottom of the water collection trough 32, which are connected to the inside of the water collection zone 5. When rainwater falls into the water collection trough 32, it can then pass through the drainage holes 33 and enter the inside of the water collection zone 5, which facilitates the collection of rainwater.
[0034] Furthermore, in order to prevent the rainwater collected inside the water collection zone 5 from freezing in cold environments, it is necessary to discharge the rainwater collected inside the water collection zone 5. A drain hole 12 is drilled on the tray 1 to communicate with the inside of the water collection zone 5. When it is necessary to discharge rainwater, the sealing plug installed at the drain hole 12 is pulled out, and then the water in the water collection zone 5 is discharged from the drain hole 12 to avoid the formation of ice inside the water collection zone 5.
[0035] Secondly, in order to prevent the drain holes 33 from being blocked, a grid plate 34 is installed inside the water collection tank 32. The grid plate 34 is installed above several drain holes 33. The grid plate 34 can intercept garbage such as leaves and plastic bags that fall on the top of the pressure plate 3, thus preventing the drain holes 33 from being blocked.
[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in order to improve the stability of the support frame formed by the assembly of the support plate 1, the support plate 2, and the pressure plate 3, two first plates 11 are fixedly installed on the top of the support plate 1, and two second plates 31 are fixedly installed on the bottom of the pressure plate 3. After the support plate 1 and the pressure plate 3 are spliced with the support plate 2, the ends of the first plates 11 and the second plates 31 are embedded in the matching slots 21, ensuring that the support plate 1 and the pressure plate 3 can be more tightly connected with the support plate 2, effectively improving the stability of the assembled support frame.
[0037] It is worth noting that when installing the porous sound-absorbing panel 4 and the polyester fiber board 6, waterproof adhesive is applied in advance to the side of the first board 11 and the second board 31 near the waterproof membrane 7. After the porous sound-absorbing panel 4 and the polyester fiber board 6 are installed inside the support frame, this waterproof adhesive can make the four edges of the waterproof membrane 7 tightly bonded to the corresponding connecting structure, preventing water leakage in the water collection area 5. At the same time, applying waterproof adhesive to the contact end face of the porous sound-absorbing panel 4 and the slot 21, as well as the top and bottom of the porous sound-absorbing panel 4, can reinforce and seal the connection between the porous sound-absorbing panel 4 and the support frame, preventing rainwater from seeping from one side of the porous sound-absorbing panel 4 into the installation area of the polyester fiber board 6, effectively improving the waterproof effect of the polyester fiber board 6.
[0038] like Figure 2 and Figure 3 As shown, to ensure the sound absorption and rainwater penetration prevention effects of the porous sound-absorbing panel 4, several staggered bidirectional holes 42 are drilled on the porous sound-absorbing panel 4. Each bidirectional hole 42 consists of two opposing channels, one facing the polyester fiber board 6 and the other facing away from the polyester fiber board 6. The two channels are arranged in an up-down configuration, which reduces the probability of rainwater passing through the bidirectional holes 42 and contacting the polyester fiber board 6. Furthermore, micropores are drilled between the two channels, making the bidirectional holes 42 more effective. 2 is presented as a bent structure, which can increase the number of sound wave reflections in the hole, extend the sound energy dissipation path, and improve the sound absorption effect; a front frame 41 is fixedly installed on the side of the porous sound-absorbing panel 4 away from the polyester fiber board 6. After the porous sound-absorbing panel 4 is installed on the support frame, waterproof glue is injected into the gap between the front frame 41 and the inner wall of the support plate 2, the gap between the top of the support plate 1, and the gap between the bottom of the pressure plate 3. This can prevent rainwater from seeping in from the gap and effectively prevent the polyester fiber board 6 from contacting rainwater.
[0039] In this embodiment, the positioning plate 13 is first fixed to the support structure with bolts to ensure that the support plate 1 can be firmly connected to the support structure as one unit, thereby improving the stability of the noise reduction device after installation. Then, the two support plates 2 are fixedly installed on the top of the support plate 1 with bolts. After the support plates 2 are installed, the ends of the overlapping porous sound-absorbing plate 4 and polyester fiber plate 6 are inserted into the slot 21 to ensure that the porous sound-absorbing plate 4 and polyester fiber plate 6 can be stably installed between the two support plates 2. Then, the pressure plate 3 is fixedly assembled on the top of the two support plates 2 with bolts. At this time, the support plate 1, support plate 2 and pressure plate 3 form a support frame. The polyester fiber plate 6 is installed inside the support frame, and the outside of the polyester fiber plate 6 is protected by the porous sound-absorbing plate 4 to prevent the polyester fiber plate 6 from being damaged by external forces.
[0040] When the noise reduction device is used outdoors, rainwater falls into the water collection trough 32 on the top of the pressure plate 3 during rainy weather, and then enters the water collection zone 5 through the drain hole 33. The water collection zone 5 collects and stores some of the rainwater. In hot weather, since the noise reduction device is placed outdoors and is easily exposed to the sun, the rainwater collected in the water collection zone 5 can cool down the polyester fiber board 6, reducing the chance of the polyester fiber board 6 being damaged by high temperature. Therefore, it can extend the service life of the polyester fiber board 6 and effectively improve the durability of the noise reduction device.
[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
