[0050] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0051] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0052] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0053] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0054] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs.

[0055] Existing generator sets cool their internal generators and engines by opening air inlets on the outer wall of the nacelle to introduce outside airflow, allowing outside air to enter the nacelle and cool the generator and engine exterior walls. However, due to the large variety of engine models and their varying sizes, the corresponding nacelle length will vary, making it difficult for the air inlets on the outer wall of the nacelle to meet the cooling needs of engines of different sizes.

[0056] Based on the above research, this disclosure provides a generator set and an internal heat dissipation device for the generator set. By providing an induced draft mechanism and an adjustment mechanism, the induced draft mechanism causes airflow inside the frame to dissipate heat from the engine. At the same time, the adjustment mechanism adjusts the distance between the two induced draft fans in the induced draft mechanism according to the length of the engine to meet the heat dissipation effect for engines of different sizes.

[0057] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0058] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0059] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0060] In some embodiments, such as Figures 1 to 2 As shown, the operator first installs the sliding guide plate 31 inside the frame 1 above the engine. Then, the T-shaped blocks 32 on the two support frames 30 slide into the sliding guide plate 31 from the sliding guide grooves 310 at both ends of the sliding guide plate 31. During this process, the axes of the drive shaft 40 and the driven shaft 41 are kept collinear. According to the volume of the engine 2 installed in the frame 1, the distance between the two support frames 30 is adjusted. At this time, the end of the drive shaft 40 slides in the through slide 411 in the driven shaft 41, and at the same time, each plug rod 42 slides in the corresponding insertion sleeve 44.

[0061] In some embodiments, such as Figure 3 As shown, after the distance between the two support frames 30 is adjusted, the motor 50 is started, and its output end drives the drive gear 51 to rotate. Through the meshing of the drive gear 51 and the driven gear 52, the drive shaft 40 connected to the driven gear 52 is driven to rotate. A driven member 431 is provided on the outer wall of one end of the drive shaft 40 located inside the through slide 411. The driven member 431 is engaged with the slot 432 in the through slide 411. Therefore, the drive shaft 40 can synchronously drive the driven shaft 41 to rotate during the rotation process. The airflow direction of the two exhaust fans 301 is the same (each exhaust fan 301 is connected to the corresponding support frame 30. This connection method is existing technology and will not be described in detail here). Therefore, airflow can be realized inside the frame 1 to cool the engine 2.

[0062] In some embodiments, protective plates are provided on the exterior of the driving gear 51 and the driven gear 52 to prevent dust carried by long-term airflow from affecting their transmission meshing. The protective plates are not shown in the figure. This is prior art and will not be described in detail here.

[0063] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.

[0064] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0065] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0066] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0067] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
