Description

Technical Field

[0001] This utility model relates to the field of generator equipment technology, specifically a silent cover for a self-cleaning, low-resistance, quiet generator set. Background Technology

[0002] Currently, generator sets generate significant noise and heat during operation. Existing soundproof enclosures generally suffer from the following defects: insufficient self-cleaning ability: after prolonged use, dust, oil, and other contaminants easily accumulate on the surface of the soundproof enclosure, requiring regular manual cleaning and resulting in high maintenance costs; high wind resistance: the traditional intake and exhaust duct designs are unreasonable, leading to high airflow resistance and affecting the unit's heat dissipation efficiency; and limited noise reduction effect: the sound insulation structure is simple and cannot simultaneously meet the requirements of low wind resistance and efficient noise reduction.

[0003] In summary, these technical deficiencies make it difficult for existing soundproof enclosures to meet the stringent requirements of high-end scenarios such as new energy power plants and data centers in terms of overall performance. There is an urgent need for an innovative solution that integrates self-cleaning, low wind resistance, and efficient noise reduction. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A self-cleaning, low-resistance, quiet generator set noise enclosure includes a base, a housing on the upper part of the base, the housing having a double-layer hollow structure, an internal mounting cavity for placing the generator set, an air inlet pipe on the top outer surface of the housing, an exhaust pipe on the rear side of the air inlet pipe, the inlets of the air inlet pipe and the exhaust pipe facing opposite directions, both the air inlet pipe and the exhaust pipe adopt a semi-buried design, the top of the housing has two air ducts for the air inlet pipe and the exhaust pipe respectively, an air intake duct and an air outlet duct, an intake fan is provided at the junction of the air inlet duct and the air outlet duct, the outer surface of the housing and the outer walls of the air inlet pipe and the exhaust pipe are all coated with a photocatalytic coating, and the inner wall of the housing is provided with a sound-absorbing cotton layer.

[0006] Preferably, the cavity inside the housing is a vacuum cavity.

[0007] Preferably, the edge of the housing on the side facing the air inlet of the air duct has a streamlined, low-resistance structure.

[0008] Preferably, the upper part of the air inlet pipe has a thickened arc-shaped structure.

[0009] Preferably, a clamshell-shaped air guide plate is provided on the top surface of the housing and inside the air inlet pipe.

[0010] Preferably, the bottom edge of the clamshell-shaped air guide plate is rotatably provided with a telescopic rod, and the other end of the telescopic rod is rotatably connected to the top surface of the shell.

[0012] Preferably, the inner wall of the inner layer of the shell is provided with an arc-shaped chamfer at the bend.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes a photocatalytic coating that can catalytically decompose surface pollutants under light, and forms a water film that carries away dust when washed by rainwater, thus reducing maintenance costs and achieving a self-cleaning effect.

[0015] This invention optimizes the airflow path by using a streamlined structure on the windward side, an arc-shaped pipe opening, and a clamshell-shaped air guide plate, thereby reducing wind resistance and wind noise.

[0016] This utility model features a double-layer shell combined with a sound-absorbing cotton layer, a vacuum environment cavity, and an arc-shaped chamfer design on the inner layer of the shell, thereby achieving a noise reduction effect.

[0017] This utility model adopts a semi-buried air duct design to reduce wind resistance, and at the same time uses a liftable clamshell air guide plate to adjust the opening and closing size according to the air intake volume, thereby dynamically adjusting the impact of air on the air intake duct and improving the overall quiet performance.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] like Figure 1-3 As shown, a self-cleaning, low-resistance, quiet generator set enclosure includes a base 1, with a housing 2 mounted on top of the base 1. The housing 2 has a double-layer hollow structure, with an outer layer of stainless steel and an inner layer of galvanized steel sheet. An installation cavity 21 is provided inside the housing for placing the generator set. An air inlet pipe 3 is provided on the top outer surface of the housing 2, and an exhaust pipe 4 is provided on the rear side. The openings of both pipes face opposite directions and are both semi-recessed. The top of the housing divides it into an air inlet duct and an air outlet duct. An intake fan 31 is provided at the junction of the air inlet and exhaust ducts of the air inlet pipe 3.

[0026] The outer surface of the housing 2 and the outer walls of the air inlet pipe 3 and the air outlet pipe 4 are coated with a TiO2 photocatalytic coating 5, and a sound-absorbing cotton layer 6 is provided on the inner wall. The inner wall of the housing has an arc-shaped chamfer 23 at the bend, and the edge of the housing on one side of the air inlet pipe 3 has a streamlined low-resistance structure 23, such as a teardrop or bullet shape, with a thickened arc-shaped structure 32 at the upper opening. A clamshell-shaped air guide plate 33 that can be driven to rotate by a telescopic rod 34 is provided inside. Preferably, the cavity inside the housing can be set as a vacuum environment 22 to enhance the sound insulation effect. In this embodiment, the telescopic rod 34 is an electrically controlled telescopic rod.

[0027] The working principle of the above technical solution is as follows:

[0028] When the generator set is running, air enters the mounting cavity 21 through the air inlet duct 31 of the air inlet pipe 3. The clamshell air guide plate 33 is linked to the opening and closing of the generator set's throttle valve, and the controller adjusts the extension and retraction of the telescopic rod 34 to adjust the opening and closing angle of the clamshell air guide plate 33, so that the airflow flows evenly through the unit for heat dissipation. The hot air is discharged through the air outlet duct 41 of the exhaust pipe 4. The photocatalytic coating 5 decomposes surface pollutants under light and achieves self-cleaning when washed by rainwater. The double-layer shell and the sound-absorbing cotton layer 6, together with the vacuum layer 22, effectively block noise transmission. In the air intake direction, the streamlined low wind resistance structure 23 can effectively reduce wind resistance, thereby reducing wind noise and improving air intake efficiency.

[0029] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
