At present, there are various power cabinet designs on the market, but most of them have obvious deficiencies in dust prevention. Traditional power cabinet adopts simple ventilation hole or gap for heat dissipation. Although this design meets the basic heat dissipation requirement, it is easy for dust, particulate matter and other impurities in the air to enter the cabinet body. Long-term accumulation will cause poor heat dissipation of electrical equipment, insulation performance degradation, and even cause short circuit, failure and other safety problems. In addition, frequent cabinet cleaning and maintenance not only increases operation and maintenance cost, but also affects the continuity and stability of power supply. SUMMARY

[0003] The utility model aims at providing a kind of power cabinet with dustproof function to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a kind of power cabinet with dustproof function, including power cabinet body, dustproof screen and limiting mechanism, the both sides of the power cabinet body are provided with heat dissipation hole, the both sides of the outer portion of the power cabinet body are provided with limiting mechanism, the limiting mechanism includes mounting bracket, rubber limiting strip and clamping strip, the other side of the mounting bracket is provided with mounting bracket, the mounting bracket and rubber limiting strip are provided with clamping strip, the inside of the power cabinet body is provided with damping roller, the outer portion of the damping roller is wound with dustproof screen, the dustproof screen one end penetrates power cabinet body, and dustproof screen bottom is clamped by rubber limiting strip and clamping strip.

[0005] When the power cabinet body is used, the heat dissipation gas enters the power cabinet body to dissipate heat for electronic components through the heat dissipation hole. The dust can be intercepted and filtered through the dustproof screen. When the dustproof screen reaches saturation state after being used for a period of time, the dustproof screen bottom is slightly clamped by the rubber limiting strip and the clamping strip, so that the staff can pull down the dustproof screen with force. Because the dustproof screen adopts easy-to-tear design, the easy-to-tear length covers the heat dissipation hole area. After pulling down the dustproof screen, tear off the saturated section, and the dustproof screen section not contaminated by dust covers the heat dissipation hole again. This design is convenient and fast for cleaning dust, realizes non-stop maintenance, is convenient for staff maintenance, effectively blocks dust particles in the air, greatly reduces the dust accumulation speed in the cabinet, prolongs the equipment maintenance period, reduces the risk of equipment failure caused by dust accumulation, improves the operation stability and reliability of the power cabinet body and its internal equipment, and ensures the continuous power supply capacity of the power system.

[0006] Preferably, the dustproof gauze is arranged outside the heat dissipation hole, and the dustproof gauze is in a segmented form.

[0007] By arranging the dustproof gauze outside the heat dissipation hole, the gas entering the inside of the heat dissipation hole can be filtered to intercept dust.

[0008] Preferably, the clamping strip is fixed on the mounting frame, and one side of the mounting frame is fixed outside the power cabinet body.

[0009] The power cabinet body can provide a mounting position for the mounting frame, and the mounting frame can provide a mounting position for the rubber limiting strip, so that the clamping strip and the rubber limiting strip can clamp the dustproof gauze.

[0010] Preferably, one side of the damping rotating roller is fixed to one side inside the power cabinet body.

[0011] The damping rotating roller can provide a mounting position for the dustproof gauze, and because one side of the damping rotating roller is fixed to one side inside the power cabinet body and the damping rotating roller has a certain damping force, the damping rotating roller can straighten the dustproof gauze by cooperating with the limiting mechanism.

[0012] In summary, the present application has the following beneficial technical effects:

[0013] The dustproof gauze is designed to be easy to tear, and the length of each easy-to-tear section covers the heat dissipation hole area. After the dustproof gauze is pulled down and the saturated section is torn off, the section of the dustproof gauze that is not contaminated by dust covers the heat dissipation hole again. This design is convenient and fast for cleaning dust, realizes maintenance without stopping, is convenient for maintenance by workers, effectively blocks dust particles in the air, greatly reduces the dust accumulation speed in the cabinet, prolongs the equipment maintenance period, and the dustproof gauze is wound on the damping rotating roller, which has good continuity.
