Abstract
Description
Technical Field
[0001] This utility model relates to the field of noise reduction and vibration damping structure technology, and in particular to a noise reduction and vibration damping device for ventilation equipment in underground garages. Background Technology
[0002] When the fans in the underground garage are running, they are prone to vibration and noise. Long-term vibration will not only affect the service life of the fans, but also cause the floor slab to vibrate. Prolonged vibration of the fans can cause the support and hanging components to loosen, creating safety hazards for the fans. The noise will also affect the daily life of residents.
[0003] Chinese patent CN215000356U discloses a heavy-duty support bracket for subway station fans, which uses a stepped columnar shock-absorbing base to reduce the impact of vibration. Chinese patent CN211623833U discloses a fan vibration damping device, which uses an elastic bracket to reduce the impact of fan vibration on the floor. However, the fans of the above two devices are fixed to the bracket with bolts. When the fan vibrates, the bolts are easy to loosen, which may cause the fan to fall. Furthermore, there are no fan noise reduction measures, which affect people's lives. Utility Model Content

Figure 4 for Figure 1 Enlarged view of section A in the middle; Figure 5 for Figure 2 Enlarged view of section B in the middle. (See image below.) Figure 1-Figure 5As shown, in this embodiment, the noise reduction and vibration damping device for the ventilation equipment in the underground parking garage includes a base plate 1, on which a hoisting assembly 2 is provided. Multiple sets of hoisting assemblies are fixedly connected at their top ends to the ceiling 3. A fan 100 is installed on the base plate 1, and an elastic limiting assembly is provided on the base plate 1. The fan 100 can be fixed or detached from the base plate 1 through the elastic limiting assembly, allowing the fan 100 to be detachably installed on the base plate 1. Furthermore, as... Figure 1 As shown, a noise-reducing telescopic enclosure 4 is installed between adjacent hoisting components 2. The noise-reducing telescopic enclosure 4 can surround the fan 100, thereby blocking the noise generated by the fan 100 when it is working.
[0032] Furthermore, in this embodiment, since the noise-reducing telescopic enclosure 4 cannot be installed at the air inlet and outlet of the fan, a fan silencer is installed at the air inlet and outlet of the fan. This arrangement can further reduce the noise generated by the fan.
[0033] Furthermore, in this embodiment, the inner wall of the noise-reducing telescopic enclosure 4 is lined with porous sound-absorbing material. This arrangement can further enhance the sound absorption effect of the noise-reducing telescopic enclosure 4 and ensure the effect of noise reduction.
[0034] Furthermore, according to one embodiment of this utility model, the hoisting assembly 2 includes a lower rod 21, a shock absorber 22, an upper rod 23, a hoisting plate 24, and an anti-seismic support rod 25. The lower rod 21 is fixedly connected to the shock absorber 22 via a connecting block 232. The shock absorber 22 is fixedly connected to the upper rod 23 via the connecting block 232. The hoisting plate 24 is fixedly connected to the end of the upper rod 23. The anti-seismic support rod 25 is hinged to the hoisting plate 24, and the top end of the anti-seismic support rod 25 is hinged to the ceiling. This configuration enables the hoisting assembly 2 to have shock absorption and anti-seismic functions, effectively reducing the vibration of the fan and improving equipment stability.
[0035] Furthermore, in this embodiment, the upper rod 23 and the lower rod 21 are provided with a plurality of hook holes 231, and the noise-reducing telescopic enclosure 4 is provided with a plurality of hooks 41 that cooperate with the hook holes 231. This arrangement can ensure the installation stability of the noise-reducing telescopic enclosure 4 and guarantee its positional accuracy.
[0036] Furthermore, in this embodiment, the hoisting plate is provided with a hinge seat 241, and an anti-seismic support rod 25 is hinged to the hinge seat.
[0037] Furthermore, according to one embodiment of this utility model, a lower groove 11 is provided on the base plate 1, and a positioning hole 12 is provided in the lower groove 11. A support plate 101 is provided below the fan, and the support plate 101 is installed in the lower groove 11. Bolts 14 are installed on the support plate 101, and the bolts 14 pass through the support plate 101 and the positioning hole 12 and are locked and fixed by nuts 15. This arrangement allows the fan 100 to be stably supported on the base plate 1 and will not detach from the base plate 1.
[0038] Furthermore, in this embodiment, a shock-absorbing rubber pad 13 is provided between the lower groove 11 and the support plate 101. This arrangement can further and effectively reduce the vibration of the fan through the shock-absorbing rubber pad 13, thereby improving the stability of the equipment.
[0039] Furthermore, such as Figure 5 As shown, the elastic limiting assembly includes a rotating shaft 16 and an elastic limiting member 17. The elastic limiting member 17 is mounted on the rotating shaft 16 and can rotate above the bolt 14 to prevent the bolt 14 from disengaging from the support plate 101. This configuration allows the fan 100 to be fixed in place by the elastic limiting assembly, ensuring that the fan 100 is stably and reliably supported on the base plate 1, preventing positional displacement and disengagement, and further effectively reducing noise generation.
[0040] Further, such as Figure 6 As shown, the elastic limiting member 17 includes an elastic plate 171 and a limiting plate 173. The elastic plate 171 has a rotating shaft hole 172 that mates with the rotating shaft 16. The elastic plate is connected to the limiting plate 173, which has two lower plates 174. When the elastic limiting member is directly above the bolt 14, the bolt 14 is positioned between the two lower plates 174. This arrangement effectively limits the bolt 14 by the two lower plates 174, ensuring that the elastic limiting member 17 provides stable and reliable support for the support plate 101 and prevents it from detaching.
[0041] According to the above-mentioned solution of this utility model, the vibration of the fan equipment can be reduced and the stability of the equipment can be improved by using the hoisting components and shock-absorbing rubber pads. The fan can be prevented from detaching by using the elastic limiting components, thus eliminating safety hazards. The operating noise can be reduced by using the noise-reducing telescopic enclosure and the fan silencer, thereby reducing the impact of noise and vibration on people's lives.
[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
