Abstract

The utility model discloses a noise reduction installation structure of a generator set. The noise reduction installation structure comprises a bottom plate, an installation plate and a connecting assembly. A plurality of containing grooves are formed in the top of the bottom plate, and rubber cushion blocks with anti-corrosion coatings are fixed in the grooves. The bottom of the mounting plate is inserted into the positioning holes of the rubber cushion blocks through the positioning columns to form a primary damping layer. Screws penetrate through the four corners of the mounting plate, the bottom ends of the screws extend to the bottom positioning grooves through the bottom plate receding holes and are in threaded connection with threaded holes of the rubber blocks in the grooves, the top ends of the screws press the mounting plate through rubber gaskets, and a damping system for limiting displacement is formed. Clamping grooves are formed in the periphery of the mounting plate and used for fixing the honeycomb-shaped silencing partition plate, and air noise transmission is blocked; and the sealing strips cover gaps between the plates, so that the sound insulation integrity is improved. The bottom of the bottom plate is provided with a drainage groove communicated with the containing groove to ensure rapid drainage of rainwater. Through the rubber cushion block and screw-rubber block two-stage damping design, vibration conduction is efficiently isolated; the honeycomb noise reduction partition board weakens combustion noise in a targeted mode, and the noise reduction reliability is remarkably improved by combining an anti-corrosion and drainage structure.

Description

Technical Field

[0001] This utility model relates to the field of generator set equipment technology, and in particular to a generator set noise reduction installation structure. Background Technology

[0002] Generator sets, as important backup or main power sources, are widely used in industrial production, construction sites, medical facilities, and data centers. However, the noise pollution they generate during operation has become a pressing issue. During traditional generator set operation, mechanical vibrations are directly transmitted to the foundation through rigid supports, causing structural resonance and radiating low-to-mid-frequency noise into the surrounding environment. Simultaneously, high-pressure gas pulsations in the combustion chamber and exhaust gas flow generate high-frequency aerodynamic noise, with sound pressure levels exceeding 100 dB, severely interfering with the surrounding environment and violating increasingly stringent environmental regulations. Current common noise reduction solutions have the following limitations: Limited vibration damping design: Most installation structures only use basic rubber pads to isolate vibration, but rubber is prone to aging and has poor deformation recovery, resulting in a significant decrease in damping effect after long-term load, leading to secondary transmission of vibration energy. Incomplete noise control: Existing technologies struggle to simultaneously address both vibration-transmitted noise and airborne noise. For example, while mounting frames reduce mechanical vibration through spring dampers, they lack effective blocking of high-frequency sound waves such as combustion noise, requiring additional soundproof enclosures, increasing cost and space requirements. Poor modular compatibility: Generator sets are typically composed of independent modules such as engines, generators, and fuel tanks, with significant differences in vibration frequencies among the components. Traditional integrated bases are prone to coupled vibrations, exacerbating noise radiation; while separate installations lack reliable displacement limiting mechanisms, posing a risk of equipment displacement. Insufficient environmental adaptability: When used outdoors, rainwater can easily seep into the gaps in the shock-absorbing structure, accelerating rubber corrosion, and water accumulation may alter the system's damping characteristics, affecting shock absorption stability.

[0003] Therefore, there is an urgent need for an installation structure that integrates multi-level noise reduction, displacement constraint and environmental protection, which can suppress vibration transmission, specifically block the propagation path of air noise, and improve the long-term reliability of equipment under complex working conditions. Utility Model Content

[0004] The purpose of this invention is to provide a noise reduction installation structure for generator sets to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A noise reduction mounting structure for a generator set includes a base plate. Multiple receiving slots are evenly distributed on the top of the base plate. A rubber pad is fixedly installed inside each receiving slot. Multiple positioning holes are provided on the top of each rubber pad. A mounting plate is fixedly installed on the top of each rubber pad. Positioning posts corresponding to the positioning holes are fixedly installed on the bottom of the mounting plate. Through holes are provided at the four corners of the top of the mounting plate, and screws are inserted into each through hole from top to bottom. Clearance holes are provided at the four corners of the top of the base plate. Positioning grooves corresponding to the clearance holes are provided on the bottom of the base plate. Rubber blocks are engaged in the positioning grooves. A connecting plate is fixedly installed on the bottom of each rubber block. A threaded hole corresponding to the screw is provided on the top of the connecting plate. The bottom end of the screw passes through the clearance hole and extends into the positioning groove, where it is screwed. A washer made of rubber is provided at the top of the screw, located between the screw head and the mounting plate.

[0007] By adopting the above technical solution, different parts of the generator set are installed on different mounting plates. Because rubber pads are set between the mounting plates and the base plate, the vibration will not be transmitted to the base plate when different modules of the generator set drive the mounting plates to vibrate, thus reducing some vibration noise. At the same time, the position of the mounting plate on the rubber pads is restricted by the cooperation of the screw, rubber blocks and washers, which prevents the entire mounting plate from shifting due to excessive amplitude. In actual use, the washers need to be replaced regularly to avoid device failure.

[0008] In a further embodiment, the surface of the rubber pad is coated with an anti-corrosion coating.

[0009] By adopting the above technical solution, since the rubber block is in long-term contact with the base plate (ground), it is necessary to carry out anti-corrosion treatment to extend the service life of the rubber pad block.

[0010] In a further embodiment, the top periphery of the mounting plate is provided with multiple slots, and a sound-absorbing baffle is fixedly installed in the slots.

[0011] By adopting the above technical solution, the noise emitted by different modules of the generator set is different. Therefore, in order to avoid some modules being too noisy (not vibration noise of mechanical parts, but combustion noise, which cannot be eliminated by vibration reduction), sound-absorbing baffles can be installed around the mounting plate of these modules to eliminate combustion noise.

[0012] In a further embodiment, the periphery of the mounting plate is covered with a sealing strip.

[0013] By adopting the above technical solution, the sealing strip is used to seal the gap between two adjacent mounting plates.

[0014] In a further embodiment, a drainage groove is provided at the bottom end of the base plate, and the drainage groove is connected to each receiving groove.

[0015] By adopting the above technical solution, this device can be used outdoors, allowing rainwater to be drained quickly.

[0016] In a further embodiment, the sound-absorbing baffle has a honeycomb structure.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By mounting different parts of the generator set on different mounting plates, and because rubber pads are placed between the mounting plates and the base plate, the vibration of the mounting plates driven by different modules of the generator set will not be transmitted to the base plate, thus reducing some vibration noise. At the same time, the position of the mounting plate on the rubber pads is restricted by the cooperation of screws, rubber blocks and washers, preventing the entire mounting plate from shifting due to excessive amplitude. In actual use, the washers need to be replaced regularly to avoid device failure. Attached Figure Description
