Description

Technical Field

[0001] This utility model relates to the field of oilfield well site noise reduction technology, and in particular to a mobile well site noise reduction device. Background Technology

[0002] With the acceleration of urbanization, more and more oil well sites within oilfield production areas are being incorporated into residential areas, schools, hospitals, office buildings, and other similar locations. The components of the pumping units, booster pumps, and other equipment within these well sites are rigidly connected without any vibration damping or buffering measures, making them highly susceptible to resonance and radiating multi-frequency noise, such as impact noise, friction noise, and noise caused by vibrations in rotating systems. This results in noise pollution of the surrounding environment, and many well sites have received complaints from residents due to excessive noise levels.

[0003] The motors of the field equipment are prominent noise sources, primarily radiating electromagnetic noise and cooling aerodynamic noise. The magnitude of electromagnetic noise is closely related to the motor's power and speed. High-power motors account for a significant portion of electromagnetic noise, reaching 89.6 dB(A) in operating noise, with a frequency range of 100-400Hz. The rotating system mainly consists of bearings, belts, and flywheels, generating noise primarily from gears and bearings. When gears reach a certain speed, their forced vibration frequency coincides with the natural frequency of the gearbox and gear carrier, resulting in resonance and a dramatic increase in radiated noise. The rotating system noise reaches 82.1 dB(A), with a frequency range of 400-2000Hz. In addition, there is noise caused by vibration and friction between relatively moving components within the pumping unit. Therefore, reducing the noise of motors and rotating systems is an effective measure to reduce the noise of well site equipment. Utility Model Content

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example 1, referring to Figures 1-9 This utility model discloses a mobile well site noise reduction device, comprising a noise reduction housing 2, an exhaust silencer 4, an intake silencer 5, and a turbine exhaust fan 6. The bottom of the noise reduction housing 2 is mounted on the pumping unit base 3. An air inlet is installed on one side of the noise reduction housing 2, and an intake silencer 5 is installed outside the air inlet. The turbine exhaust fan 6 and an air outlet are installed on the top of the noise reduction housing 2, and an exhaust silencer 4 is installed outside the air outlet. The noise reduction housing 2 includes a steel frame body 2. 1. Sound insulation panel 2.2 and sound insulation door 2.3: Sound insulation panel 2.2 and sound insulation door 2.3 are installed on the outside of the main steel frame 2.1. The sound insulation panel 2.2 and sound insulation door 2.3 have a hollow layer 2.2.1 in the middle. The inner wall of the sound insulation panel 2.2 and sound insulation door 2.3 is pasted with a damping sound insulation felt layer 7. The damping sound insulation felt layer 7 is a sound insulation material with environmentally friendly polyvinyl chloride as the main material. It has the best sound insulation effect for low frequency noise, which can reach 20dB(A).

[0027] The hollow layer 2.2.1 of the sound insulation panel 2.2 is provided with polyester fiber sound-absorbing cotton layers 2.2.2 on both sides, and the thickness of the sound insulation panel 2.2 is 100 mm or 120 mm, wherein the hollow layer 2.2.1 is 20 mm thick, and the polyester fiber sound-absorbing cotton layers 2.2.2 on both sides are 40 mm or 50 mm thick respectively.

[0028] The aforementioned air intake silencer 5 has a cuboid structure, including rainproof louvers 5.1, silencer housing 5.2, and sound-absorbing blades 5.3. Multiple rainproof louvers 5.1 are provided at the front inlet of the silencer housing 5.2, and longitudinally installed sound-absorbing blades 5.3 are distributed in the inner cavity of the silencer housing 5.2.

[0029] The aforementioned sound-absorbing blade 5.3 has a 135° angled structure.

[0030] The aforementioned soundproof door 2.3 is connected to the adjacent soundproof panel 2.2 via a hinge 2.5. The adjacent soundproof panels 2.2 are connected by a snap fastener and have internal latches.

[0031] The aforementioned soundproof door 2.3 is equipped with a soundproof window 2.7 and a door handle 2.6, and at least one soundproof panel 2.2 is equipped with a soundproof window 2.7.

[0032] The exhaust silencer 4 is a cuboid structure, similar to the intake silencer 5. This structure does not have a rainproof top. Since the device is placed outdoors and the oil pump does not need to be rainproof, it only needs to reduce noise.

[0033] In use, the steel frame body 2.1, which houses the soundproof panel 2.2 and the soundproof door 2.3, is hoisted onto the pumping unit base 3 on one side of the pumping unit balance box 1. The base 2.4 is then bolted to the pumping unit base 3. Seams on the soundproof panel 2.2 and the soundproof door 2.3 are sealed with sealing strips. The soundproof panel is externally connected by snap fasteners and internally fitted with latches, achieving sealing, anti-theft, and detachable functionality. The mother-and-child soundproof door 2.3 serves as the ladder entrance for the pumping unit. In summer, the soundproof window 2.7 and the soundproof door 2.3 can be opened for ventilation and heat dissipation. A 3mm thick damping sound insulation felt 7 is laid on the inner wall of the soundproof panel 2.2 and the soundproof door 2.3. This environmentally friendly polyvinyl chloride-based sound insulation material provides the best sound insulation effect for low-frequency noise, reaching 20dB(A). The soundproof panel 2.2 and the soundproof door 2.3 are designed to be 4 cm + 2 cm + 4 cm thick. The hollow structure of 5cm+2cm+5cm enhances sound absorption and insulation performance. The polyester fiber sound-absorbing cotton on both sides not only meets safety and environmental protection requirements but also improves the sound absorption effect of the noise reduction device on low and mid-frequency noise. A turbine exhaust fan 6 and an exhaust silencer 4 are added to the top of the noise reduction enclosure 2, while an intake silencer 5 is installed at the bottom. This ensures both heat dissipation and noise reduction. The intake and exhaust silencers are 800*800*600mm in size, and the internal sound-absorbing blades are 135° angled to increase the sound wave contact area and maximize sound absorption. All soundproof panels and doors are removable, allowing for repositioning and repeated use.
