Description
Technical Field
The utility model relates to the technical field of electrical equipment manufacturing, in particular to an air filtering structure for a power distribution cabinet.
Background
The switch board is distribution system's last-stage equipment, switch board internally mounted has a lot of electrical components, in order to guarantee electrical components's heat dissipation, generally all can set up the louvre on the switch board, in order to guarantee the circulation of air, avoid electrical components overheated phenomenon that can not normally work to take place, and in order to avoid the dust in the air to enter into the inside of switch board from the louvre department, generally all can install the filter screen in the louvre department, will accumulate more dust on the long filter screen of time, lead to the jam of filter screen, will influence the normal heat dissipation of switch board inside like this, so need in time change the filter screen, however when operational environment's cleanliness factor is relatively poor, the frequency of changing the filter screen is high, the waste time.
Disclosure of Invention
The utility model aims to solve the technical defects and provides an air filtering structure for a power distribution cabinet, which can reduce the frequency of replacing a filter screen.
The utility model discloses an air filtering structure for a power distribution cabinet, which comprises the power distribution cabinet, wherein a heat dissipation hole is formed in the power distribution cabinet, a filtering device is arranged on the heat dissipation hole, the filtering device comprises a rectangular box body, a filter screen, a fan, a pressure release block and rectangular mounting plates, an air inlet is formed in one of two opposite side surfaces of the rectangular box body, an air outlet is formed in the other side surface of the rectangular box body, one side of the fan is arranged on the air outlet, the other side of the fan is arranged on the heat dissipation hole, the rectangular mounting plates are arranged in the rectangular box body at intervals along the direction from the air inlet to the air outlet, the periphery of the rectangular mounting plates are bonded and sealed with the inner wall of the rectangular box body, the rectangular mounting plates are provided with mounting holes and pressure release holes, the filter screen is arranged on the mounting holes, and the pressure release block is arranged in the pressure release holes.
When the technical scheme is used, the fan is turned on, air in the working environment passes through the air inlet on the rectangular box body, then is filtered through the filter screen, passes through the air outlet on the rectangular box body, finally enters the power distribution cabinet through the radiating hole, impurities are firstly trapped on the filter screen on the first rectangular mounting plate at the air inlet, when the impurities trapped by the filter screen on the first rectangular mounting plate are too much to cause the air to be difficult to pass through, the negative pressure enables the pressure relief block on the first rectangular mounting plate to be separated from the pressure relief hole, air is subjected to air inlet through the pressure relief hole on the first rectangular mounting plate, then the impurities in the air are trapped by the filter screen on the second rectangular mounting plate, and so on.
Furthermore, the rectangular box body is made of transparent materials, so that the use condition of the filter screen can be conveniently observed.
Further, the upper end of the rectangular mounting plate is fixed with the top of the rectangular box body, the top of the rectangular box body and the rectangular box body are detachably arranged, the top of the rectangular box body is detached, and the rectangular mounting plate and a filter screen on the rectangular mounting plate can be taken out for replacement, so that the rectangular mounting plate is convenient to replace.
The beneficial effects of the utility model are as follows: through setting up polylith rectangle mounting panel, be provided with filter screen, pressure release hole and pressure release piece on every rectangle mounting panel, when the front end filter screen was plugged up by impurity, the pressure release piece was broken away from in the pressure release hole, made the air still pass through, then used subsequent filter screen to filter in proper order, can reduce the change frequency of filter screen.
