Many people find it difficult to understand why sprinklers need to play music . Moreover, it is always far enough to hear those familiar songs, such as "Good Life, Peace", "Happy Birthday," "Only Mom is Good," and so on. But in fact, this music is indeed indispensable. When sanitation sprinklers passed, they could often see pedestrians escaping from the streets and dodging as soon as they were not washed. If this is even worse on a rainy day, it is not just a “cool shower†but it is directly a clay figurine. When a sprinkler is sprinkling water in the city center, it is inevitable that pedestrians will be spilled on the road because of high traffic. When passing through pedestrian-intensive areas, the sprinkler driver turns the water down so that the amount of water sprinkling is not as great as possible. Avoid spilling to pedestrians as much as possible. Sprinklers spray high pressure water aside, clear the dust on the road, sprinkler music sound is used to remind everyone to hide to avoid being sprayed. Sometimes, many people think that the music of the sprinkler can sometimes cause noise and seriously affect everyone's life, such as listening to the high school entrance examination. When Xiaobian thinks it is important, we must set a reminder on the road. The sprinkler will definitely go around. There are now two yellow arrow warning lights installed behind the sprinkler. Use the flashing warning light to remind the vehicle behind and pass the message “Sprinkler in front, please pay attention to avoidanceâ€. As for the vehicles in front, because the sprinklers are large and easy to find, and the speed of the sprinklers is only 15 kilometers per hour, it is not a problem. The warning is still in the testing stage. Before the popularity, Xiaobian thought that the music of the sprinkler was still necessary.
