Display screens are installed on highways to display warning information, lane information, speed limit information, etc. However, due to the particularity of the highway environment, there is a lot of dust. When the display screen is dissipating heat, the outside air passes through the dustproof net and enters the shell of the display screen for ventilation and heat dissipation. Dust is easy to accumulate on the surface of the dustproof net. After a long time, the dustproof net will be blocked, which greatly reduces the heat dissipation performance. The inside of the display screen shell rises abnormally, causing damage to the display screen. The dustproof net needs to be cleaned regularly to avoid clogging.
