Description

Technical Field

[0001] The utility model relates to a power distribution cabinet with convenient replacement of dustproof nets. Background Art

[0002] At present, many distribution cabinets will install dust screens at the vents to prevent dust from entering the cabinet through the vents and prevent dust from affecting the normal operation of electrical components in the cabinet; after the dust screen has been used for a period of time, the dust attached to it will gradually accumulate and affect ventilation, so the dust screen needs to be replaced regularly; the dust screens of many existing distribution cabinets are usually installed close to the vents with bolts. When replacing, it is necessary to use a screwdriver to unscrew the bolts, and at the same time, it is necessary to prevent the dust shaken off the dust screen from falling into the distribution cabinet from the vents, which makes the replacement of the dust screen of the distribution cabinet inconvenient; therefore, it is necessary to develop a distribution cabinet with easy replacement of dust screens to solve the above problems. Utility Model Content

[0005] A power distribution cabinet for convenient replacement of dust screens, comprising a cabinet body, a connecting port being provided on the top wall of the cabinet body, a ventilation assembly being provided on the top of the cabinet body, the ventilation assembly comprising a ventilator fixed to the top of the cabinet body, a plurality of ventilation holes being provided on the side walls of the ventilator, a cover plate being provided on the top of the ventilator, a mounting ring being provided on the inner wall of the ventilator, a mounting rod corresponding to the mounting ring being provided at the bottom of the cover plate, the mounting rod passing through the mounting ring, a spring being provided between the mounting ring and the cover plate, an annular seat being provided on the top of the cabinet body and the bottom of the cover plate, a dust screen being provided between the two annular seats.

[0006] Preferably, both of the two annular seats are provided with an annular slot, and the upper and lower side edges of the dustproof net are respectively inserted into the two annular slots.

[0007] Preferably, a sealing ring is fixedly provided on the bottom of the cover plate, and the sealing ring is in contact with the inner wall of the ventilator.

[0008] Preferably, the edge of the top of the cabinet is in a bevel shape.

[0009] Preferably, there are four mounting rods and four mounting rings, each mounting ring corresponds to a mounting rod, and the four mounting rings are arranged in an X shape on the inner wall of the ventilator.

[0010] The beneficial effect of the utility model is that when replacing the dustproof net, one only needs to pull the cover plate upwards so that the annular seat at the bottom of the cover plate is separated from the dustproof net by a certain distance, and then the dustproof net can be taken out from the annular seat on the top of the cabinet for replacement. The operation is simple and convenient. During the replacement process, the dust shaken off the dustproof net will fall on the top of the cabinet. There is no need to worry about the shaken dust entering the cabinet. This part of the dust can be wiped off during replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figures 1 to 5A power distribution cabinet for convenient replacement of dust screens shown in the figure comprises a cabinet body 11, a connecting port 12 is provided on the top wall of the cabinet body 11, a ventilation assembly 13 is provided on the top of the cabinet body 11, the ventilation assembly 13 comprises a ventilating tube 14, the ventilating tube 14 is fixed on the top of the cabinet body 11, a plurality of ventilation holes 15 are provided on the side wall of the ventilating tube 14, a cover plate 16 is provided on the top of the ventilating tube 14, a mounting ring 22 is provided on the inner wall of the ventilating tube 14, a mounting rod 21 corresponding to the mounting ring 22 is provided at the bottom of the cover plate 16, the mounting rod 21 passes through the mounting ring 22, and the mounting ring 22 is provided. 2 and the cover plate 16 are provided with a spring, the top of the cabinet 11 and the bottom of the cover plate 16 are provided with an annular seat 18, and a dust net 19 is provided between the two annular seats 18; the cover plate 16 is pulled upward to separate the annular seat 18 at the bottom of the cover plate 16 from the dust net 19 by a certain distance, and then the dust net 19 can be taken out from the annular seat 18 at the top of the cabinet 11 for replacement, which is simple and convenient to operate. During the replacement process, the dust shaken off the dust net 19 will fall on the top of the cabinet 11, and there is no need to worry about the shaken dust entering the cabinet 11. This part of the dust can be wiped off during replacement.

[0019] Furthermore, an annular slot 20 is provided on the two annular seats 18, and the upper and lower side edges of the dustproof net 19 are respectively inserted into the two annular slots 20; the dustproof net 19 is inserted between the two annular slots 20, so that the dustproof net 19 is stably installed, and when the cover plate 16 is lifted to move the annular seat 18 upward, the dustproof net 19 can also be quickly separated from the annular seat 18.

[0020] Furthermore, a sealing ring 17 is fixedly provided at the bottom of the cover plate 16 , and the sealing ring 17 is in contact with the inner wall of the ventilating tube 14 ; the sealing ring 17 can enhance the sealing performance of the connection between the cover plate 16 and the ventilating tube 14 .

[0021] Furthermore, the edge of the top of the cabinet 11 is in a sloped shape; when it rains, rainwater falling on the top of the cabinet 11 can quickly flow away along the slope at the top edge of the cabinet 11 to avoid accumulation of water.

[0022] Furthermore, there are four mounting rods 21 and four mounting rings 22, each mounting ring 22 corresponds to a mounting rod 21, and the four mounting rings 22 are arranged in an X shape on the inner wall of the ventilator 14; when the cover plate 16 is lifted upward, the springs on the four mounting rods 21 jointly pull the cover plate 16, and the mounting rods 21 are also restricted by the mounting rings 22 and can only move vertically, so that the cover plate 16 will not be offset when it is lifted, and the cover plate 16 can be reset by loosening the cover plate 16 under the action of the spring.

[0023] According to the working principle of the utility model, ventilation can be achieved in the distribution cabinet through the ventilation holes 15 on the ventilation tube 14, and the dustproof net 19 can block the dust in the external environment to prevent dust from entering the cabinet 11; when the dust on the dustproof net 19 gradually accumulates and needs to be replaced, the cover plate 16 is pulled upward, so that the annular seat 18 at the bottom of the sealing ring 17 moves up and is separated from the dustproof net 19 by a certain distance. At this time, the dustproof net 19 is taken out from the annular seat 18 at the top of the cabinet 11. The dust shaken off during the removal of the dustproof net 19 will fall on the top of the cabinet 11. This part of the dust is wiped off, and then a new dustproof net 19 is inserted into the annular seat 18 at the top of the cabinet 11, and the cover plate 16 is loosened. The spring between the mounting ring 22 and the cover plate 16 causes the cover plate 16 to move down and reset, and the top of the dustproof net 19 is inserted into the annular seat 18 at the bottom of the cover plate 16, thereby completing the replacement of the dustproof net 19.

[0024] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
