An outdoor power distribution cabinet that uses air as power to reduce airflow vibration

Abstract

The invention relates to the technical field of power distribution cabinets, an outdoor power distribution cabinet that uses air as power to reduce airflow vibration, including a cabinet body, the inner bottom wall of the cabinet body is fixedly connected with a drainage mechanism, and the upper part of the drainage mechanism is fixedly connected with a support The upper part of the support plate is fixedly connected with a vibration-absorbing mechanism, and the drainage mechanism includes a cover body. Both side walls of the cover body are provided with suction ports, and the inner bottom wall of the cover body is fixedly connected with a deflector plate. A vibrating ring is fixedly connected above the flow plate, and a vibration cavity is formed between the vibrating ring and the deflector plate, and a magnetic sheet is fixedly connected above the vibrating ring, because the principle of noise generation inside the power distribution cabinet is that between components Therefore, the vibration law of the vibrating film can be changed by adjusting the tightness between the magnetic sheet and the washer. When the vibration law of the vibrating film is adjusted to be opposite to that of the cabinet, vibration and sound can be eliminated. Effect.

[0002] The most commonly used type of power distribution cabinet is the box-type power distribution cabinet, which includes a box body and a power distribution cabinet body. The box body provides protection, installation and heat dissipation functions; specifically, louvers or convection holes are set on the box body to achieve heat dissipation. Function, prefabricated foundations such as raft boards are set inside the box to fix the main body of the power distribution cabinet; after a long period of use, we found that the design efficiency of the existing convection holes in the box is very low, and the heat inside the box rises and is concentrated in the At the top, the convection holes on the side of the box are difficult to completely replace the internal hot air; if the cooling holes are set on the top of the box cover, although the hot air can be discharged quickly, a large part of the box-type power distribution cabinets are set in Outdoors, this structure greatly increases the possibility of water entering the interior, causing damage to the device

[0003] In the process of researching the heat dissipation technology of the box-type power distribution cabinet, we found that inside the box, the heat sink is installed on the surface of the power distribution cabinet to improve the heat dissipation capacity, but a large amount of heat emitted by the heat sink is accumulated inside the box. It is difficult to dissipate heat immediately. Even if a fan is installed to extract the internal hot air, the heat dissipation effect is poor due to the single direction of the fan. There are too many internal dead angles to achieve the effect of heat dissipation. Very annoying buzzing noise accompanied by vibration, this noise will not only affect people's work and rest in daily life, more seriously, it will cause neurasthenia of residents living nearby, so a kind of air is used as power to reduce Airflow Vibration Outdoor Distribution Cabinet
