A watering control device of a watering cart comprises a magnet, a proximity switch, a pressure switch, a power supply, an electromagnetic water valve and a support. A water inlet P of the electromagnetic water valve is communicated with a water tank, a first water outlet A of the electromagnetic water valve is communicated with a water inlet of a manual ball valve, and a second water outlet B ofthe electromagnetic water valve and a water outlet of the manual ball valve are both communicated with a water inlet of the water pump through a water pump water inlet pipe; the proximity switch, thepressure switch, the power supply and the wiring end K of the electromagnetic water valve are electrically connected in sequence to form a loop; when the wiring end K of the electromagnetic water valve is electrified, the water inlet P of the electromagnetic water valve is communicated with the second water outlet B; when the wiring end K of the electromagnetic water valve loses power, the water inlet P of the electromagnetic water valve is communicated with the first water outlet A; the magnet is fixedly connected to a handle of the manual ball valve; and the proximity switch corresponds to the magnet. After the water pump is maintained, even if a driver forgets to open the manual ball valve, the water pump cannot suck water during working.
一种洒水车的洒水控制装置，包括、磁体、接近开关、压力开关、电源、电磁水阀、支架；所述电磁水阀的进水口P与水箱连通，电磁水阀的第一出水口A与手动球阀的进水口连通，电磁水阀的第二出水口B和手动球阀的出水口均通过水泵进水管与水泵的进水口连通；所述接近开关、压力开关、电源和电磁水阀的接线端K依次电连接并形成回路；当电磁水阀的接线端K得电时，电磁水阀的进水口P与第二出水口B连通；当电磁水阀的接线端K失电时，电磁水阀的进水口P与第一出水口A连通；所述磁体固定连接在手动球阀的手柄上；所述接近开关与磁体相对应。本发明能实现维修水泵结束后即使驾驶员忘记打开手动球阀也不会使水泵工作时吸不到水。
