Description

Technical Field

[0001] This utility model belongs to the field of generator set technology, specifically relating to generator sets and induced draft devices for generator sets. Background Technology

[0002] 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, the air guides at the air inlets are usually fixed, causing the air entering the nacelle to flow in a fixed direction. Fixed air guides result in a single airflow direction, which is difficult to cover the complex curved surface structure of the engine exterior, leading to insufficient cooling in some areas.

[0003] Therefore, an exhaust fan for motor sets and generator sets is designed to solve the technical problem in the prior art where the fixed-direction airflow is difficult to cover the complex curved surface structure of the engine's outer wall, resulting in insufficient heat dissipation in local areas.

[0029] Research has revealed that existing generator sets cool their internal generators and engines by opening air inlets on the outer wall of the nacelle to introduce external airflow, allowing outside air to enter the nacelle and cool the generator and engine exterior. However, the air guides at the air inlets are usually fixed, causing the air entering the nacelle to flow in a fixed direction. The fixed air guides result in a single airflow direction, which is difficult to cover the complex curved surface structure of the engine exterior, leading to insufficient cooling in some areas.

[0030] Based on the above research, this disclosure provides an exhaust fan for a motor set and a generator set. The exhaust fan mechanism introduces air from outside the frame into the frame, and a drive mechanism drives an adjustment mechanism to change the direction of the airflow passing through the air guide plate. By using a reciprocating deflection method, the airflow direction is changed periodically, so that the airflow alternately covers different areas, thereby improving the uniformity of heat dissipation.

[0031] 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.

[0032] 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.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] In some embodiments, such as Figure 1 and Figure 2As shown, the induced draft box 20 is fixed on the frame 1 and located on one side of the engine 5 (several removable protective plates are provided on the outer wall of the frame 1, and each protective plate is not shown in the figure). During the operation of the engine 5, the motor 22 suspended in the induced draft box 20 is started, and its output end drives the rotating shaft 23 to rotate, which in turn drives the induced draft fan 24 connected to the rotating shaft 23 to rotate, introducing air from outside the frame 1 into the interior of the frame 1. The airflow direction is adjusted by each air guide plate 21 to dissipate heat from the outer wall of the engine 5.

[0035] In some embodiments, such as Figure 3 As shown, during the rotation of the rotating shaft 23, it drives the active bevel gear 30 on its outer wall to rotate. At this time, the active bevel gear 30 meshes with the driven bevel gear 32 (the active and driven bevel gears are equipped with a protective mechanism to prevent them from being affected by external dust, which is prior art and is not shown in this figure), driving the driven shaft 31 to rotate (the driven shaft 31 is suspended inside the induced draft box 20 by a fixing rod 35, and the driven shaft 31 and the fixing rod 35 are connected by a bearing). At this time, the drive disk 33 rotates accordingly, driving the driven rod 34, which is connected to the drive disk 33 by a bearing, to move. As shown in the figure, one end of the driven rod 34 is connected to the surface of the drive disk 33 by a bearing and is located in an eccentric position. The other end of the driven rod 34... One end is connected to the bearing of the adjusting rod 40. As the drive disc 33 rotates, the driven plate 34 drives the adjusting rod 40 to move up and down reciprocally under the limit of the limiting member 41. Since the adjusting rod 40 is connected to the rack 42, the rack 42 follows the adjusting rod 40 to move up and down reciprocally, driving each adjusting gear 43 meshing with the rack 42 to rotate back and forth. Each adjusting gear 43 is fixed to the corresponding rotating shaft 210, and each air guide plate 21 is fixed on the corresponding rotating shaft 210. At this time, each air guide plate 21 is driven to reciprocate around the axis of the rotating shaft 210 to change the direction of the airflow passing through each air guide plate 21. By periodically changing the direction of the airflow, the airflow alternately covers different areas, improving the uniformity of heat dissipation.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.
