Dustproof heat dissipation power distribution cabinet for expressway

Abstract

The invention discloses a dustproof heat dissipation power distribution cabinet for the expressway, which comprises a hollow power distribution cabinet shell, wherein a first mounting cavity is formedin the top wall of the power distribution cabinet shell, an air collection chamber is welded to the inner bottom wall of the power distribution cabinet shell, a plurality of air inlet holes are formed in the bottom wall of the air collection chamber, the power distribution cabinet shell is rotatably connected with a rotating shaft through a bearing in a penetrating mode, the end, which is locatedoutside the power distribution cabinet shell, of the rotating shaft is in interference fit with a wind wheel, a rotating disc is glued to the end, which is located in the first mounting cavity, of the rotating shaft, the power distribution cabinet shell and the air collection chamber are jointly and fixedly connected with a plurality of conductive pins in a penetrating mode, and the ends, which are located in the air collection chamber, of the conductive pins are sharp ends. The power distribution cabinet has the advantages that ventilation can be performed in the power distribution cabinet forcibly, a better heat dissipation effect is achieved, dust can be prevented from entering the power distribution cabinet, damage to components of the power distribution cabinet caused by the dust isavoided, and meanwhile, the temperature of the power distribution cabinet can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a dust-proof and heat-dissipating power distribution cabinet for expressways. Background technique [0002] With the continuous development of the economy, the number of highways is also increasing. Street lights, speed measuring equipment, warning equipment, monitoring equipment, etc. are generally installed on the highway. These equipment need power supply, in order to facilitate management and subsequent troubleshooting, etc. Yes, many power distribution cabinets are often installed on expressways, and the power distribution cabinets are connected to provide unified power supply to ensure the normal use of high-speed equipment. [0003] In the prior art, the heat dissipation of existing power distribution cabinets often relies on natural wind to ventilate and dissipate heat through the through holes in the side walls of the power distribution cabinet. The heat dissipat...
