[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Depend on Figure 1 and Figure 2 As shown, it is a structural schematic diagram of the diesel generator set in this embodiment, including a protective shell 1, a diesel generator body 2 and an exhaust pipe 3. The diesel generator body 2 is additionally provided with a protective shell 1, and an exhaust pipe 3 is fixedly installed on the top of the protective shell 1. The exhaust pipe 3 is communicated with the exhaust port of the diesel generator body 2. A noise reduction mechanism 4 for absorbing noise is installed at the side opening of the protective shell 1. The noise reduction mechanism 4 includes an opening and closing plate 41, a rotating frame 42, a locking assembly 43 and a sound-absorbing layer 44. The rotating frame 42 is rotatably installed at the side opening of the protective shell 1, the opening and closing plate 41 is fixedly installed on the side of the rotating frame 42, the locking assembly 43 is installed on the inner side of the opening and closing plate 41, and the sound-absorbing layer 44 is symmetrically installed on the side of the opening and closing plate 41 close to the diesel generator body 2.

[0029] During use, the device is placed at the target location, and then the diesel generator body 2 is operated to provide power to the connected device. When the diesel generator body 2 is running, the diesel generator body 2 itself will generate certain noise due to the operation of internal components. At this time, with the cooperation of the sound-absorbing layer 44 and the protective shell 1, the noise emitted by the diesel generator body 2 is absorbed, the decibel of the noise is reduced, and the impact of the equipment on the surrounding environment during operation is reduced.

[0030] By the attached Figure 3 As shown, it is a structural diagram of the noise reduction mechanism 4 in this embodiment. The sound-absorbing layer 44 is made of sound-absorbing cotton, and hemispherical sound-absorbing grooves are equidistantly provided in the sound-absorbing layer 44. During use, the sound-absorbing layer 44 can absorb and silence the noise generated during the operation of the diesel generator body 2, thereby reducing the decibel of the noise. The sound-absorbing grooves of the sound-absorbing layer 44 itself are provided so that sound waves enter the sound-absorbing grooves, collide with the inner wall of the sound-absorbing grooves, and are then absorbed by the sound-absorbing layer 44, thereby extending the path of sound wave conduction and facilitating more stable noise reduction processing of the subsequent sound-absorbing layer 44.

[0031] By the attached Figure 3As shown, it is a structural diagram of the noise reduction mechanism 4 in this embodiment. The noise reduction mechanism 4 also includes a noise reduction strip 45. The noise reduction strip 45 is installed at the side edge of the opening and closing plate 41. During use, the installation of the noise reduction strip 45 allows the opening and closing plate 41 to be more stable when closing the side opening of the protective shell 1. When the diesel generator body 2 is subsequently running, it will drive the protective shell 1 to vibrate as a whole, and the installation of the noise reduction strip 45 can reduce the noise generated by the collision between the opening and closing plate 41 and the protective shell 1, thereby achieving noise reduction operation.

[0032] By the attached Figure 4 The figure shows the structure of the filter mechanism 5 in this embodiment. The diesel generator set also includes a filter mechanism 5, which includes an air intake window 51, a fixed frame 52, and a filter plate 53. The air intake window 51 is installed on the side of the protective housing 1 near the air intake end of the diesel generator body 2. The fixed frame 52 is arranged on the side of the air intake window 51, and the filter plate 53 is fixedly installed within the fixed frame 52. During use, the air intake window 51 cooperates with the air intake end of the diesel generator body 2 to collect gas required for equipment operation. The fixed frame 52 and the filter plate 53 cooperate to prevent dust and impurities in the air from entering the diesel generator body 2 through the air intake end, affecting the stability of the diesel generator body 2 during operation. Moreover, excessive internal impurities during operation of the diesel generator body 2 can affect the normal coordination and operation of the internal components of the diesel generator body 2, resulting in increased noise generated by the components during operation.

[0033] By the attached Figure 5 As shown, reinforcement grooves are equidistantly provided inside the protective shell 1 on the side of the fixed frame 52, and the reinforcement rods pass through the fixed frame 52 and are threadedly connected to the reinforcement grooves. During use, the fixed frame 52 is installed to the side of the protective shell 1 to block the entire air intake window 51. Then, the installation and positioning of the fixed frame 52 are quickly completed by using the reinforcement rods.

[0034] By the attached Figure 6 As shown, it is a structural diagram of the shock absorbing mechanism 6 in this embodiment. The diesel generator set also includes a shock absorbing mechanism 6, which includes a matching frame 61, a connecting frame 62, a conveying wheel 63 and a shock absorbing assembly 64. The matching frame 61 is symmetrically fixedly installed on the lower surface of the protective shell 1, the connecting frame 62 is rotatably installed on the side of the matching frame 61, the conveying wheel 63 is installed on the side of the connecting frame 62, and the shock absorbing assembly 64 is rotatably installed between the connecting frame 62 and the protective shell 1.

[0035] During use, the use of the conveying wheel 63 assists the overall stable movement of the equipment, which facilitates the transportation of the equipment. When the diesel generator body 2 is in operation, the protective shell 1 is in a vibrating state as a whole. At this time, the matching frame 61 will change the overall angle of the connecting frame 62 due to the overall vibration and up and down shaking of the protective shell 1. At this time, the shock absorbing component 64 will dampen the frequency of the connecting frame 62's own shaking, reduce the frequency of the overall shaking of the equipment, and reduce the noise generated by the collision of various components during the overall shaking of the equipment.

[0036] By the attached Figure 6 As shown, the shock absorbing assembly 64 consists of two groups of rotating seats and shock absorbers. The ends of the rotating seats are fixedly connected to the surface of the connecting frame 62 and the lower surface of the protective shell 1 respectively. The rotating seats are symmetrically installed at both ends of the shock absorber. During use, the shock absorber can stably provide a shock absorbing effect to the entire equipment and reduce the noise generated during the operation of the equipment.

[0037] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
