[0030] In this embodiment, a ladder 21 is fixedly connected to the tail of the water tank 2, and the ladder 21 is used to climb to the top of the water tank 2.

[0036] In this embodiment, the spray gun 4 is connected to the water tank 2 via a water pump 5 .

[0037] To sum up, the water level intelligent control system of the sprinkler truck is equipped with a water tank. When in use, water is first poured into the water tank through the water inlet pipe. When the water level line reaches the position of the topmost conductive electrode tube, all the conductive electrode tubes will be connected through the water resistor. At this time, each output end presents a high potential, which is transmitted to the circuit board through the electrical signal, and the water full state is displayed on the display screen. After spraying for a certain period of time, the water level line drops. When the water level line reaches the height of different conductive electrode tubes, the input end voltage is higher than the inverting input end, so that the output end presents a high potential, which is transmitted to the circuit board through the electrical signal, and different water level states can be displayed on the display screen, thereby achieving the purpose of displaying the remaining water amount in the water tank, solving the problem in the prior art that when the sprinkler truck is working, it is difficult to control the working distance, resulting in the water often running out halfway through the spraying, or a lot of water remaining in the water tank after the spraying work is completed.

[0038] The intelligent water level control system of the sprinkler truck is equipped with a first electric push rod. By adjusting the working parameters of the first electric push rod during operation, the height of the spray pipe from the ground can be adjusted through the scissor frame, and then the water pressure of the spray pipe on the road surface can be adjusted. By setting a second electric push rod, the second electric push rod is extended to drive the two auxiliary spray pipes to extend to both sides of the vehicle body, thereby increasing the spraying area and improving work efficiency.

[0039] In practice, water is first poured into the tank through the inlet pipe. When the water level reaches the topmost conductive electrode tube, all conductive electrode tubes become connected through the water resistor. At this point, all output terminals exhibit a high potential, which is transmitted via an electrical signal to the circuit board, indicating a full state on the display. After a certain period of spraying, the water level drops. When the water level reaches the height of different conductive electrode tubes, the input terminal voltage becomes higher than the inverting input terminal, causing the output terminal to exhibit a high potential. This electrical signal is transmitted to the circuit board, indicating different water level states on the display. For example, when the water level drops to the middle conductive electrode tube, the display reads "Medium"; when the water level drops to the lowest conductive electrode tube, the display reads "Low." This real-time monitoring and display function enables operators to accurately assess the remaining water level in the tank and effectively plan watering operations.

[0040] During sprinkler operations, the height of the sprinkler pipe from the ground can be adjusted via the scissor frame by adjusting the length of the first electric push rod. For example, when high-pressure road washing is required, the first push rod can be shortened to bring the sprinkler pipe closer to the ground, thereby increasing water pressure. Conversely, when evenly spraying a wider road surface, the first push rod can be extended to move the sprinkler pipe away from the ground, thereby reducing water pressure and expanding the spraying range. This flexible height adjustment function allows the sprinkler truck to adapt to different road surfaces and environmental requirements.

[0041] Example 2: Based on the sprinkler truck water level intelligent control system of Example 1, the present invention is further illustrated and described below.
