[0002] Municipal sprinkler trucks refer to special vehicles used for watering and cleaning urban roads, squares, parks, etc. It is usually equipped with a large-capacity water tank that can carry several cubic meters of water to meet the needs of long-term operation. The high-pressure water spraying system of the sprinkler truck can effectively clean the garbage, dust and dirt left by large vehicles on the road, so that the urban roads are kept clean and tidy. The sprinkler truck can transport water to green areas such as flower beds, parks, and road green spaces, contributing to the beautification of the city and environmental protection. The high-pressure water spraying system carried by the sprinkler truck can quickly extinguish fires and prevent the spread of fires. At the same time, it can also provide sufficient water to meet the needs of front-line fire rescue personnel. When the sprinkler truck is operating, the existing fixed nozzle only sprays water in a single direction of the road section where the sprinkler truck is traveling, and at a single fixed height in some areas, it affects the range in which the nozzle can spray water.
