Abstract
Description
Technical Field
[0001] This utility model belongs to the field of generator set technology, specifically relating to generator sets and induced draft dust removal devices. Background Technology
[0002] Existing generator sets cool their 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. To prevent outside dust from entering the cabinet, filters are usually installed at the air inlets to intercept dust. However, this method requires regular cleaning of the filter surface; otherwise, it will affect the entry of outside air into the cabinet, resulting in untimely heat dissipation inside the cabinet.
[0003] Therefore, a generator set and an induced draft dust removal device are designed to solve the technical problem that the filter screen at the air inlet needs to be cleaned manually and regularly in the existing technology.

[0055] Research has found that existing generator sets cool their 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. To prevent outside dust from entering the cabinet, filters are usually installed at the air inlets to intercept dust. However, this method requires regular cleaning of the filter surface; otherwise, it will affect the entry of outside air into the cabinet, resulting in untimely heat dissipation inside the cabinet.
[0056] Based on the above research, this disclosure provides a generator set and a dust removal device. By providing a dust removal device, during the operation of the generator and engine inside the cabinet, the air outside the cabinet is introduced into the cabinet by the air removal mechanism to dissipate heat from the generator and engine. At the same time, the dust removal mechanism intercepts dust. When it is necessary to clean the dust filter, the air removal mechanism is simply reversed, and the dust removal brush removes the dust adhering to the dust filter. The dust is then blown away from the cabinet by the reversed air removal mechanism.
[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 protective plate on the surface of cabinet 1 is not shown), when the generator 3 and engine 4 inside cabinet 1 start working, the motor 230 is started, and its output end drives the exhaust fan 232 to rotate. Due to the presence of the one-way bearing 240, the rotating shaft 241 is stationary at this time. The exhaust fan 232 introduces the air outside cabinet 1 into the interior of cabinet 1 and blows it toward the generator 3 and engine 4 to cool them down. The cooled air is discharged through the exhaust port 10. The outside air is filtered by the dust filter 22, and the dust in the air is intercepted and stays on the surface of the dust filter 22.
[0061] When the motor 230 has been working for a period of time and it is necessary to clean the dust on the surface of the dust filter 22, the motor 230 is reversed. Its output end drives the exhaust fan 232 to reverse. The exhaust fan 232 drives the rotating shaft 241 to rotate through the one-way bearing 240. The rotating shaft 241 and the fixed part 242 are connected by the bearing so that the rotating shaft 241 can drive the cleaning brush 243 to rotate normally. During the rotation, the cleaning brush 243 removes the dust adhering to the surface of the dust filter 22 and scrapes it off the surface of the dust filter 22. At this time, because the exhaust fan 232 is reversed, the air outlet direction is towards the outside of the cabinet 1. That is, at this time, the exhaust fan 232 blows the scraped dust away from the cabinet 1.
[0062] 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.
[0063] 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.
[0064] 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.
[0065] 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.
[0066] 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.
