Description

Technical Field

[0001] The utility model belongs to the technical field of diesel generator sets, and in particular relates to a box-type silent diesel generator set. Background Art

[0002] A diesel generator set is a small power generation device that uses diesel as fuel and a diesel engine as the prime mover to drive the generator to generate electricity. Compared with an open generator set, a silent generator set adds a device on its basis, uses an outer shell to enclose the open generator set, and adheres sound insulation material to the inner wall of the outer shell to make the generator set soundproof and rainproof.

[0003] In the prior art, a Chinese utility model patent with authorization announcement number CN220452034U discloses "a portable diesel generator set", including a shell, a partition fixedly connected to the inside of the shell, and a generator, a diesel engine and a battery are arranged on the partition; the bottom of the shell is rotatably connected to a bidirectional screw rod, and two moving blocks are threadedly connected to the bidirectional screw rod, one end of the bidirectional screw rod is provided with a motor, the bottom of the moving block is rotatably connected to a first connecting rod and a second connecting rod, the bottom end of the first connecting rod is rotatably connected to a mounting plate, the bottom of the mounting plate is provided with casters, the bottom of the second connecting rod is rotatably connected to a stabilizing block, and the bottom of the stabilizing block is provided with a grip cone and a friction pad.

[0004] Although the silent diesel generator set in the prior art has the advantages of low noise and easy mobility, the noise reduction effect is not obvious.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Since the internal components of the diesel generator set body 1 and the working principle of the diesel generator set body 1 are existing technologies that have been disclosed on the market, they will not be described in detail in this article.

The cross section of the baffle frame 33 is wavy. Therefore, when in use, the diesel generator set body 1 can be ventilated and dissipated through the upper heat sink 31 and the lower heat sink 32 to ensure the reliability of the operation of the diesel generator set body 1. The lower heat sink 32, whose upper half is rectangular and whose lower half is an isosceles trapezoid, cooperates with the shielding frame 33 with a wavy cross section. The noise sound waves can be blocked and reflected by the lower heat sink 32 and the shielding frame 33, so that most of the noise sound waves can attenuate and offset each other, making it impossible for the sound waves to pass through the rectangular heat dissipation port 21, and the noise reduction effect is further improved.

[0028] Depend on Figure 1 and Figure 2 As shown, as an optional embodiment, in this embodiment, the shielding frame 33 is a rubber component, which has a certain flexibility and can absorb part of the noise sound waves.

[0030] Depend on Figure 1 and Figure 3As shown, as an optional embodiment, in this embodiment, the mobile support mechanism 5 includes a support frame 51, a lifting plate 52, a moving wheel 53, a moving seat 54, a bidirectional threaded rod 55, a servo motor 56 and a flip support arm 57. The support frame 51 is fixed to the bottom end of the diesel generator set body 1, the lifting plate 52 is located in the support frame 51, and the four moving wheels 53 are diagonally fixed to the bottom surface of the lifting plate 52. The two moving seats 54 are symmetrically distributed in the support frame 51, and the bidirectional threaded rod 55 is rotatably installed in the support frame 51, and the bidirectional threaded rod 55 passes through the moving seat 54 and is connected to the moving seat 54 by threaded engagement. The servo motor 56 is fixed on the support frame 51 to drive the bidirectional threaded rod 55 to rotate. The two groups of flip support arms 57 are symmetrically distributed, and the top of the flip support arm 57 is hinged to the lifting plate 52. The two ends are hinged with the corresponding moving seats 54. When the diesel generator set body 1 needs to be moved, the servo motor 56 is started to drive the bidirectional threaded rod 55 to rotate, so that the two moving seats 54 move away from the outside under the action of thread rotation, and at the same time, the flip support arm 57 is pushed to flip and move, and the flip support arm 57 is used to push the lifting plate 52 down until the four moving wheels 53 touch the ground and lift the diesel generator set body 1, which is convenient for movement; when working, the servo motor 56 is started to drive the bidirectional threaded rod 55 to rotate in the opposite direction, so that the two moving seats 54 move toward the inside under the action of thread rotation, and at the same time, the flip support arm 57 is pulled to flip and move, and the lifting plate 52 is pulled up by the flip support arm 57, so that the lifting plate 52 and the four moving wheels 53 are retracted into the support frame 51. At this time, the support frame 51 is used to stably support the diesel generator set body 1.

[0037] During operation, the servo motor 56 is started to drive the bidirectional threaded rod 55 to rotate in the opposite direction, so that the two moving seats 54 move closer to the inside under the action of the thread rotation, and at the same time, the flip support arm 57 is pulled to flip and move, and the flip support arm 57 is used to pull the lifting plate 52 up, so that the lifting plate 52 and the four moving wheels 53 are retracted into the support frame 51. At this time, the support frame 51 is used to stably support the diesel generator set body 1.

[0038] It should be noted that the servo motor 56 is a conventional device purchased on the market with a built-in power switch. Technicians in this field can make a conventional selection according to usage requirements.
