Description

Technical Field

[0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a dustproof mechanism of a power distribution cabinet. Background Art

[0002] A power distribution cabinet is a device used to distribute power resources, protect circuits, and control the operation of electrical equipment. It is equipped with various electrical components, such as circuit breakers, contactors, relays, and instruments, to achieve the normal operation and fault protection of the power system. In order to prevent external dust from entering the power distribution cabinet and affecting the normal operation of electrical components, a filter dust screen is usually installed at the air inlet of the power distribution cabinet. The function of the filter dust screen is to intercept dust in the external air and ensure that the air entering the power distribution cabinet is relatively clean.

[0003] When the electrical components inside the existing power distribution cabinet are running for a long time, it is inevitable that a lot of heat will be generated. Usually, a heat dissipation fan is set to dissipate heat. In order to prevent the heat dissipation fan impeller from blowing the dusty air outside into the power distribution cabinet to damage the electrical components, a filter dust net is set to filter and intercept the dust in the air and blow it into the inside of the power distribution cabinet, thereby realizing dust prevention for the power distribution cabinet. Although the filter dust net can effectively block dust, as time goes by, a lot of dust will inevitably accumulate on the filter dust net. If it is not cleaned in time, the blockage of the filter dust net will hinder the air circulation and reduce the air flow entering the power distribution cabinet, thereby affecting the heat dissipation effect and causing the internal electrical components to overheat. The heat dissipation fan needs a larger power to overcome the resistance of the blockage, which will increase energy consumption and increase operating costs. In order to avoid the above situation, personnel need to regularly disassemble and clean the filter dust net, which takes a lot of time and manpower, and increases maintenance costs. During the disassembly and cleaning process, the power distribution cabinet needs to be temporarily shut down, affecting the continuous operation of the power system. Summary of the invention

DETAILED DESCRIPTION

[0026] like Figure 1 , 2As shown in 3 and 6, the scraping and cleaning mechanism includes a slide rail 204 arranged on the left and right sides of the mounting shell 208, a sliding frame plate 202 is slidably arranged between the two slide rails 204, and two sliding posts 209 corresponding to the left and right positions are slidably arranged on the inner rear side of the sliding frame plate 202, and a rotating frame 203 is arranged on the opposite inner ends of the two sliding posts 209, and a connecting frame 211 is rotatably arranged inside the two rotating frames 203, and the middle parts of the two connecting frames 211 are rotatably connected by a pin shaft, and the two connecting frames 203 are connected to each other by a pin shaft. 11 are rotatably provided with a rotating seat 212 on the front side, a mounting frame 210 is provided between the front sides of the two rotating seats 212, a cleaning brush plate 215 is slidably provided inside the mounting frame 210, the front side of the cleaning brush plate 215 contacts the rear side of the filter dustproof net 107, an elastic compensation unit is provided between the rotating frame 203 and the sliding frame plate 202, a quick disassembly mechanism for quickly disassembling and assembling the cleaning brush plate 215 is provided inside the mounting frame 210, and a driving sliding frame plate 204 is provided inside the left slide rail 204. 2, the elastic compensation unit includes a spring 216 arranged between the rotating frame 203 and the sliding frame plate 202, and the plurality of springs 216 are respectively sleeved on the outer arc surface of the corresponding sliding column 209, the quick disassembly mechanism includes two locking columns 213 slidably arranged inside the installation frame 210, and the cleaning brush plate 215 is provided with two locking holes inside, and the two locking columns 213 are respectively plugged into the adjacent locking holes, and a pull plate 214 is arranged between the upper ends of the two locking columns 213, and the pull plate 214 An elastic driving unit is arranged between the pull plate 214 and the mounting frame 210, and the elastic driving unit includes a plurality of springs 217 arranged between the pull plate 214 and the mounting frame 210. The plurality of springs 217 are respectively sleeved on the outer arc surfaces of the corresponding locking columns 213. The driving unit includes a screw rod 207 arranged inside the left slide rail 204, and the sliding frame plate 202 is threadedly connected to the screw rod 207. A motor 201 is arranged at the upper end of the left slide rail 204, and the output shaft of the motor 201 is connected to the upper end of the screw rod 207 through a coupling.

[0027] like Figure 1 As shown, a control panel 103 is disposed on the front side of the cabinet door 102 , and the motor 201 , the cooling fan 106 and the electric push rod 301 are all electrically connected to the control panel 103 .

[0028] The cabinet door 102 is opened by handle 1, and the electrical device is placed on the bottom wall of the cabinet 101 so that it is located between the two clamping fixing plates 302. The control panel 103 is then used to control the electric push rod 301 to open and operate. The telescopic end drives the clamping fixing plates 302 on both sides to approach each other to fix the electrical device. The cable connected to the electrical device is connected from the line inlet, and then the cabinet door 102 is closed by handle 1. The control panel 103 is then used to control the cooling fan 106 to open and operate. The impeller rotates to blow external air into the interior of the cabinet 101 through the filter dustproof net 107, and the heat generated when the electrical device is running is discharged from the heat dissipation slot 105, thereby achieving heat dissipation of the electrical device inside the cabinet 101. At the same time, dust resistance is also taken into account, and personnel can observe the operating status of the internal electrical device through the glass observation window.

[0029] When too much dust accumulates on the filter dust screen 107, the control panel 103 is used to control the motor 201 to start running, and the output shaft drives the screw rod 207 to rotate, thereby driving the cleaning brush plate 215 on the sliding frame plate 202 to move downward to scrape off the dust accumulated on the rear side of the filter dust screen 107 to clean the filter dust screen 107. When the cleaning brush is in contact with the filter dust screen 107 for a long time, the cleaning brush plate 215 will inevitably wear out, resulting in a gap between the dust filter and the cleaning brush plate 215. The elastic force of the springs 216 on both sides can drive the rotating frames 203 on both sides to approach each other, and drive the internal connecting frame 211 to rotate and contract around the pin shaft, thereby driving the mounting frame 210 on the rotating seats 212 on both sides and the internal cleaning brush plate 215 to be close to the filter dust screen 107, thereby increasing the life of the cleaning brush plate 215.

[0030] When cleaning and scraping the filter dustproof net 107, the scraped dust can fall into the inside of the collection box 205 on the placement plate 206 to collect the dust. Then, the staff can handle the dust inside the collection box 205 through the handle.

[0031] When the cleaning brush plate 215 is worn out and needs to be replaced, by pulling the pull plate 214, the locking columns 213 on both sides can be driven to leave the locking holes of the cleaning brush plate 215. At this time, the spring 217 is in a stretched state. Then the old cleaning brush plate 215 is taken out, and then the new cleaning brush plate 215 is slid into the interior of the installation frame 210 so that the locking holes correspond to the positions of the locking columns 213. Then the pull plate 214 is released. At this time, the spring rebounds quickly and drives the locking columns 213 to be inserted into the locking holes on the cleaning brush plate 215, thereby realizing the quick disassembly and installation of the cleaning brush plate 215.

[0032] According to another embodiment of the present invention, Figure 1As shown, a support mounting frame 104 is provided at the lower end of the cabinet 101, and a plurality of mounting holes are opened inside the support mounting frame 104. The support mounting frame 104 is used to stably support the cabinet 101, and the mounting holes inside the support mounting frame 104 can be used to install the cabinet 101 by bolts, thereby ensuring that the internal dustproof mechanism operates more stably.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
