[0002] Active filter cabinet is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power. It can compensate for harmonics with varying magnitude and frequency as well as varying reactive power. In the field of DC switch cabinets, it is very common to use active filters as components of switch cabinets.

[0003] At present, when the existing active filter cabinet is in use, the electrical components inside it will generate heat, and long-term operation in a hot environment will easily damage the electrical components inside. In order to reduce the damage to the electrical components caused by heat, heat dissipation is generally achieved through heat dissipation windows, and dust and mosquitoes are blocked through dustproof nets. However, after long-term use, a lot of dust will adhere to and accumulate on the dustproof net, which makes the ventilation effect of the dustproof net worse, thereby making the heat dissipation effect worse. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an active filter cabinet with a dust cleaning structure to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an active filter cabinet with a cleaning structure, comprising an active filter cabinet body and a dustproof net, both sides of the active filter cabinet body are provided with a cleaning mechanism, the cleaning mechanism is composed of a driving motor, a support shaft, a gear, a gear ring and a cleaning brush, the support shaft is rotatably connected to both sides of the active filter cabinet body through a bearing, the gear sleeve is arranged on the outer surface of the support shaft, both sides of the active filter cabinet body are welded with a support frame, the gear ring is movably connected to the inner side of the support frame, the cleaning brush is welded and connected to the inside of the gear ring, and dustproof nets are provided in the heat dissipation windows on both sides of the active filter cabinet body.

[0006] Preferably, a driving motor connected to the support shaft via a coupling is mounted on the mounting plate at one end of the support frame, and the gear is meshingly connected with the ring gear.

[0007] Preferably, both ends of the gear ring are provided with support grooves, and the outer surface of the active filter cabinet and the inner surface of the support frame are both welded with support columns.

[0008] Preferably, the support groove is configured as an annular structure, and the gear ring and the support frame form a sliding structure through the support groove and the support column.

[0009] Preferably, a connection mechanism extending to the inside of the dustproof net is arranged inside the active filter cabinet, and the connection mechanism consists of a supporting spring, a movable column, a connection plate and a connection groove.

[0010] Preferably, the support spring is welded and connected to a groove inside the active filter cabinet, the movable column is welded and connected to one side of the support spring, the connecting plate is movably connected to one side of the movable column, and the connecting groove is opened on one side of the dustproof net.

[0011] Preferably, the connecting plate and the movable column form a rotating structure through a rotating shaft, the dust screen and the active filter cabinet form a snap-fit ​​structure through the connecting plate and the connecting groove, and the connecting plate is arranged as an inverted "L"-shaped structure.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. The existing active filter cabinet uses a dustproof net to block dust and mosquitoes, but a lot of dust will adhere to and accumulate on the dustproof net, which makes the ventilation effect and heat dissipation effect of the dustproof net worse. The utility model is provided with a dust cleaning mechanism. When the driving motor is working, the output end of the driving motor drives the support shaft and the gear to rotate. Since the gear is meshed with the gear ring, and the gear ring is slidably connected with the support frame through the support column and the support groove, the gear ring and the dust cleaning brush rotate together, so that the dust on the dustproof net can be cleaned by the dust cleaning brush, thereby preventing the dust from adhering and accumulating on the dustproof net, resulting in poor ventilation effect and heat dissipation effect.

[0014] 2. The existing active filter cabinet installs the dust screen by screws, which makes the installation and removal of the dust screen inconvenient. The utility model is provided with a connecting mechanism. Since the connecting plate and the movable column are rotatably connected by a rotating shaft, and the movable column is elastically connected to the active filter cabinet body by a supporting spring, after the dust screen is placed in the ventilation window, it can be aligned with the connecting groove by rotating the connecting plate. After loosening the connecting plate, the connecting plate will be reset and stuck into the connecting groove under the action of the supporting spring, thereby facilitating the installation of the dust screen in the heat dissipation window. The above operation can be repeated in reverse to realize the removal of the dust screen. The operation process is simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS
