Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction and heat dissipation of diesel generators, in particular to a diesel generator with a noise reduction function. Background Art

[0002] A diesel generator is a power generation device that uses diesel as fuel. The diesel engine drives the generator, converting mechanical energy into electrical energy. Interceptor plates with heat dissipation holes are installed on both sides of the diesel generator body, primarily for heat dissipation and protection. The heat dissipation holes help dissipate heat generated during operation, preventing overheating; while the interceptor plates prevent external debris from entering the generator, providing protection. This design ensures stable operation and long-term use of the diesel generator.

[0003] However, in the prior art, the intercepting plates with heat dissipation holes on both sides of the diesel generator are mostly single-layered. When the heat dissipation holes are severely blocked by dust, debris, etc. and cannot be effectively cleared using conventional cleaning tools, it is necessary to remove the intercepting mesh plates for more thorough cleaning. The intercepting plates need to be removed from both sides of the diesel generator. At this time, the diesel generator continues to work, and its internal cooling fan will introduce a large amount of dust into the diesel generator shell. The dust adheres to the heat dissipation components inside the generator, which will reduce the heat dissipation efficiency, cause the generator to overheat, and affect its performance and life. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem that in the prior art, the intercepting plates with heat dissipation holes on both sides of the diesel generator are mostly single-layered. When the heat dissipation holes are seriously blocked by dust, debris, etc. and cannot be effectively cleared using conventional cleaning tools, it is necessary to remove the intercepting mesh plates for more thorough cleaning. The intercepting plates need to be removed from both sides of the diesel generator. At this time, the diesel generator continues to work, and the cooling fan inside it will introduce a large amount of dust into the diesel generator shell. The dust adheres to the heat dissipation components inside the generator, which will reduce the heat dissipation efficiency, cause the generator to overheat, and affect its performance and life. A diesel generator with noise reduction function is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A diesel generator with a noise reduction function includes a diesel generator body and a noise reduction plate. A mounting groove is provided on the side of the diesel generator body. A vertical plate is symmetrically fixed to the top of the mounting groove on the side of the diesel generator body with bolts. A horizontal plate is vertically fixed to the bottom of the side of the vertical plate. An inner intercepting plate is fixed to the bottom of the horizontal plate with fixing bolts. A substitute component for intercepting waste dust from the diesel generator body is provided at the top edge of the horizontal plate.

[0007] Optionally, the replacement component includes an outer intercepting plate, a limiting plug rod, and an auxiliary column, wherein the top of one of the horizontal plates is rotatably connected to the auxiliary column, and the bottom of the auxiliary column is fixedly provided with the outer intercepting plate.

[0008] Optionally, a limiting rod is movably inserted into the top of the other horizontal plate, and an anti-breakage plate is fixedly provided on the top of the limiting rod of the horizontal plate.

[0009] Optionally, the outer intercepting plate is provided with a limiting hole away from the top of the auxiliary column, and the diameter of the limiting hole is the same as the diameter of the limiting rod.

[0010] Optionally, a noise reduction plate is fixedly installed inside the installation groove, and rectangular grooves are equidistantly arranged on the side of the noise reduction plate along the vertical direction.

[0011] Optionally, heat dissipation holes are equidistantly arranged on the sides of the outer interception plate and the inner interception plate, the positions of the heat dissipation holes arranged on the sides of the outer interception plate and the inner interception plate correspond one to one, and the sides of the outer interception plate are all arranged to be arc-shaped surfaces.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The utility model is provided with inner interception plates inside the mounting grooves on both sides of the diesel generator body, and a replacement component based on the outer interception plate is provided on the side of the inner interception plate. The outer interception plate is responsible for the heat dissipation and dust blocking function of the diesel generator body when the diesel generator body is working normally. When the outer interception plate needs to be cleaned, the outer interception plate can be turned away from the side of the inner interception plate. The inner interception plate can temporarily replace the outer interception plate to undertake the heat dissipation and dust blocking function of the diesel generator body, avoiding the need to remove the interception plate from both sides of the diesel generator. At this time, the diesel generator continues to work, and the internal cooling fan will introduce a large amount of dust into the diesel generator shell. The dust adheres to the heat dissipation components inside the generator, which will reduce the heat dissipation efficiency and cause the generator to overheat, affecting its performance and life.

[0020] Reference Figure 1-3 A diesel generator with noise reduction function includes a diesel generator body 1 and a noise reduction plate 4. A mounting groove 2 is opened on the side of the diesel generator body 1. A vertical plate 6 is symmetrically fixed to the top of the mounting groove 2 on the side of the diesel generator body 1 by bolts. A horizontal plate 9 is vertically fixed to the bottom of the side of the vertical plate 6. An inner intercepting plate 5 is fixed to the bottom of the horizontal plate 9 by fixing bolts 10. A substitute component for intercepting waste dust for the diesel generator body 1 is provided at the top edge of the horizontal plate 9. The substitute component includes an outer intercepting plate 3, a limiting plug rod 8, and an auxiliary column 11. The cross-sectional dimensions of the inner intercepting plate 5 and the outer intercepting plate 3 are the same as those of the mounting groove 2.

[0021] The top of one of the horizontal plates 9 is rotatably connected to an auxiliary column 11, and an outer intercepting plate 3 is fixedly provided at the bottom of the auxiliary column 11. The top of the other horizontal plate 9 is movably inserted into a limiting rod 8, and the horizontal plate 9 is fixedly provided with an anti-slip plate 7 on the top of the limiting rod 8. A limiting hole 32 is provided on the outer intercepting plate 3 away from the top of the auxiliary column 11. The diameter of the limiting hole 32 is the same as the diameter of the limiting rod 8. The anti-slip plate 7 prevents the limiting rod 8 from being lost after being pulled out from the top of the horizontal plate 9.
