Description

Technical Field

[0001] This application relates to the field of generator sets, specifically to a corrosion-resistant and noise-reducing containerized generator set. Background Technology

[0002] Generator sets are commonly used in infrastructure construction, communication stations, and disaster relief. They are characterized by their ease of use and high efficiency. However, because generator sets generate significant noise and hot air due to engine radiation, which can cause discomfort and annoyance to nearby residents, silencers are necessary to reduce noise and exhaust heat.

[0003] Chinese patent document CN220395833U discloses a containerized generator set with a built-in muffler, specifically disclosing a container, generator set, base fuel tank, and muffler. An installation space is reserved between the generator set and the top wall of the container, and the muffler is installed in this space. The muffler is connected to an exhaust pipe that passes through the top wall of the container and extends above it, forming a structure for exhausting smoke from above the container. This utility model, by installing the muffler inside the container, not only allows for overall shipment, reducing transportation costs and subsequent installation and commissioning labor costs, but also improves the overall reliability of the equipment, results in a cleaner appearance, better noise reduction, and reduces the muffler's susceptibility to damage, thus eliminating the risk of muffler theft.

[0004] However, the aforementioned patents rely solely on silencers on the top wall of the container for noise reduction, resulting in poor overall noise reduction and failing to meet practical usage requirements. Utility Model Content

[0005] In order to overcome the problem of poor noise reduction effect of existing containerized generator sets, this application provides a corrosion-resistant and noise-reducing containerized generator set.

[0006] This application adopts the following technical solution: a corrosion-resistant and noise-reducing containerized generator set, including a container and a generator set body disposed in the container. The generator set body is assembled along the length direction of the container. The container has air inlets on two side walls along the length direction. The air inlets are close to the front side of the generator set body.

[0007] An air intake silencing assembly is provided on the inner side of the housing and on the front side of the generator set body. The air intake silencing assembly includes several L-shaped first silencing plates, and an air intake channel is formed between two adjacent first silencing plates.

[0008] An exhaust silencing assembly is provided on the inner side of the housing and at the rear of the generator set body. The exhaust silencing assembly includes an exhaust pipe and several inverted V-shaped second silencing plates. An air outlet channel is formed between two adjacent second silencing plates and the air outlet channel is connected to the exhaust pipe.

[0009] Optionally, the air inlet silencing assembly is disposed between the two air inlets and located on the front side of the housing, and the air exhaust silencing assembly is disposed on the rear side of the housing.

[0010] Optionally, the air intake silencing assembly consists of two air intake silencing modules, each of which consists of at least four first silencing plates. The two silencing modules and the two air inlets are respectively and corresponding to each other. A plurality of the first silencing plates in the same silencing module are equidistantly spaced along the length of the housing.

[0011] Optionally, the dimensions of several first sound-absorbing plates within the same sound-absorbing module gradually decrease along the length of the enclosure.

[0012] Optionally, the exhaust silencing assembly further includes a housing, which is through-shaped along the length of the box, and a plurality of second silencing plates are laid inside the housing.

[0013] Optionally, a primary silencer and a secondary silencer are sequentially provided on the exhaust duct. The primary silencer and the secondary silencer are spaced apart along the width direction of the housing, and both the primary silencer and the secondary silencer are located inside the housing.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. The installation of air intake silencer and air exhaust silencer can effectively reduce the noise generated from the air intake and exhaust when the generator set is working, improve the overall noise reduction effect, and solve the problem of discomfort such as irritability caused by noise to nearby people.

[0016] 2. The design of the air intake channel of the air intake silencer and the air outlet channel of the air exhaust silencer can guide the orderly flow of air, which helps to improve ventilation efficiency;

[0023] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] like Figure 1-4 As shown, the corrosion-resistant and noise-reducing containerized generator set includes a container 1 and a generator set body 2 housed within the container 1. The generator set body 2 is assembled along the length of the container 1. The container 1 has air inlets 10 on two side walls along its length, with the air inlets 10 located near the front of the generator set body 2. An air intake silencer 3 is located inside the container 1 and at the front of the generator set body 2, and an exhaust silencer 4 is located inside the container 1 and at the rear of the generator set body 2. This layout allows air to enter and exit the container 1 in an orderly manner. During the air intake and exhaust process, the air intake silencer 3 and the exhaust silencer 4 reduce noise. At the same time, it can better cope with the hot air generated when the generator set is working, that is, effectively guide the hot air out, thereby achieving the effect of reducing noise and improving the surrounding environment.

[0025] The air intake silencing assembly 3 includes several L-shaped first silencing plates 31. An air intake channel 32 is formed between two adjacent first silencing plates 31, through which air enters the housing 1. The first silencing plates 31 are fixed to the inner wall of the housing 1 by bolts or welding to ensure stability. The air intake silencing assembly 3 is located between two air inlets 10 and at the front of the housing 1. The air intake silencing assembly 3 consists of two air intake silencing modules, each composed of at least four first silencing plates 31. The two silencing modules are respectively and one-to-one with the two air inlets 10. Several first silencing plates 31 within the same silencing module are equidistantly spaced along the length of the housing 1. This arrangement makes the air intake more uniform and better reduces intake noise. The dimensions of the several first silencing plates 31 within the same silencing module gradually decrease along the length of the housing 1, allowing for more targeted elimination of noise at different frequencies based on the characteristics of the intake air.

[0026] The exhaust silencing assembly 4 includes an exhaust duct 41 and several inverted V-shaped second silencing plates 42. The exhaust duct 41 is used to exhaust the hot air and exhaust gas generated by the generator set. Several inverted V-shaped second silencing plates 42 are laid between the exhaust duct 41 and the generator set body 2, and an air outlet channel 43 is formed between two adjacent second silencing plates 42, which is connected to the exhaust duct 41. The exhaust silencing assembly 4 also includes a housing 44, which is through-type along the length of the housing 1, and several second silencing plates 42 are laid inside the housing 44. The housing 44 can protect the second silencing plates 42 and also better guide the airflow. A primary silencer 411 and a secondary silencer 412 are sequentially installed on the exhaust duct 41. The primary silencer 411 and the secondary silencer 412 are spaced apart along the width of the housing 1, and both the primary silencer 411 and the secondary silencer 412 are located inside the housing 1. The primary silencer 411 and the secondary silencer 412 can selectively use either reactive or resistive silencers, depending on the situation, to further reduce exhaust noise through two-stage silencing. Meanwhile, the first and second sound-absorbing panels 31 and 42 are generally made of materials with good sound absorption properties, such as sound-absorbing cotton panels or porous metal panels. Sound-absorbing cotton panels are lightweight and have good sound absorption effects, effectively absorbing noise generated during air intake; porous metal panels have the advantages of high strength and corrosion resistance, making them suitable for use in harsher environments. The appropriate panel can be flexibly selected based on the installation and usage environment.

[0027] The implementation principle of this embodiment is as follows: through a reasonable layout and the setting of the air intake silencer assembly 3 and the exhaust silencer assembly 4, the noise and hot air generated by the generator set during operation are effectively reduced to minimize their impact on the surrounding environment. The air intake silencer assembly 3 absorbs noise during the air intake process through the L-shaped first silencer plate 31 and the air intake channel 32; the exhaust silencer assembly 4 further reduces noise during the exhaust process through the inverted V-shaped second silencer plate 42, the air outlet channel 43, and the primary silencer 411 and the secondary silencer 412. Meanwhile, the entire structure is integrated within the housing 1, offering advantages such as corrosion resistance, convenient overall shipping, and reduced transportation and installation costs.

[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
