Description

Technical Field

[0001] The invention relates to the technical field of engines, and in particular to a silent cover of a diesel generator set. Background Art

[0002] Diesel generator sets have always had the disadvantages of large vibration and noise. From the causes and locations of the noise, the noise of diesel generator sets mainly includes the exhaust noise of the diesel engine, the exhaust noise of the cooling fan, and the working noise of the diesel engine and the generator. The original diesel generator sets are all scattered, loosely structured, occupy a large area, and have poor noise reduction effects. The silent covers of diesel generator sets on the current market are generally made as a whole. In order to reduce the noise of the diesel generator set during operation, sound insulation materials and noise reduction structures are often designed inside the cover. For example, a sound insulation layer is set on the side wall or top of the cover, or a muffler is installed at the air inlet and exhaust port to reduce the spread of noise. However, the diesel generator set will generate a lot of heat during operation, so the cover must have good ventilation and heat dissipation performance and dustproof structure. The cover currently used is usually bolted to the generator base, which is inconvenient to disassemble through bolt connection. In the later use process, the bolt disassembly will be cumbersome when the diesel generator set is repaired, which will reduce the maintenance efficiency of the staff.

[0003] Therefore, we have made improvements to this and proposed a silent cover for diesel generator sets. Summary of the invention

[0004] The object of the present invention is to provide a silent cover for a diesel generator set to solve the problems raised in the above-mentioned background technology.

[0028] The support seat 3 includes a first climbing platform 31 and a second climbing platform 31. The first climbing platform 31 and the second climbing platform 32 are both U-shaped, and both ends of the first climbing platform 31 and the second climbing platform 32 are provided with slopes 33. A hydraulic push rod 4 is connected in the middle of the first climbing platform 31 and the second climbing platform 32. The first climbing platform 31 is fixed to one side of the base 22, and the second climbing platform 32 is fixed to one side of the base 1. The first climbing platform 31 and the second climbing platform 32 are respectively installed on the base 1 and the base 22. As the base 1 and the base 22 open and close to both sides, the engine bracket 5 slides along the first climbing platform 31 and the second climbing platform 32, and the engine bracket 5 is lifted or lowered, which is convenient for installing the engine group.

[0029] The engine bracket 5 includes a mounting frame 51, a roller 52 is installed at the bottom of the mounting frame 51, a connecting groove 53 is opened in the middle of the roller 52, and various components of the engine group are installed on the mounting frame 51 through the connecting groove 53 to ensure the stability of the engine group.

[0030] The cover assembly 6 includes a plurality of first frames 61 and a plurality of second frames 62 in a trapezoidal shape, and connecting members 64 are fixedly installed at the upper and lower ends of the first frames 61 and the second frames 62. A movable door panel 63 is provided in the middle of the first frame 61 and the second frame 62, and the upper and lower ends of the movable door panel 63 are hinged to the connecting member 64. A limiting slot 65 and an inspection window 66 are provided in the middle of the movable door panel 63, and an inspection door 7 is installed inside the inspection window 66. The plurality of movable door panels 63 connected in series are convenient for the storage and use of the cover assembly 6 as a whole when folded in a W shape, and when the movable door panel 63 is unfolded and installed on the base 1 and the base 2, the inspection door 7 is fixedly installed.
