Sewage suction truck with intelligent anti-overflow system and control method of sewage suction truck
The invention relates to a sewage suction truck with an intelligent anti-overflow system and a control method of the sewage suction truck. The sewage suction truck comprises an electric control system, a second-stage chassis, a tank, a vacuumizing system, the intelligent anti-overflow system, a sewage suction pipe and a sewage discharging pipe. The liquid level height of media in the tank is monitored in real time. When the tank full calibration value is achieved, an on-off signal is triggered through a liquid level monitor device, a tank top door pump air cylinder is connected to control a four-way valve to achieve reversing, automatic unloading is achieved, and an alarm is given out to achieve prompting. The defects that an existing anti-overflow system of a sewage suction truck can onlysealed mechanically, vacuum suction force cannot be turned off in time, liquid sewage is prone to being sucked into a pipeline assembly, a filter system and a power system, consequently, the maintenance cost is high, and even the systems are damaged are overcome. The sewage suction truck has the tank full automatic unloading function and the tank full alarm function, operators are liberated fully, and the labor intensity is greatly reduced.
本发明涉及一种具有智能防溢系统的吸污车及其控制方法，该吸污车包括电控系统、二类底盘、罐体、抽真空系统、智能防溢系统、吸污管和卸污管，实时监测罐内介质液位高度，当达到罐满标定值时，通过液位监测装置触发开关信号，接通罐顶门泵气缸控制四通阀换向，实现自动卸荷，并报警提醒，解决现有吸污车防溢系统只能依靠机械密封，不能及时关断真空吸力，易将液态污物吸入管路总成、过滤系统、动力系统中，导致维修费用高，甚至损坏系统的弊病。本发明具有罐满自动卸荷功能和罐满报警功能，充分解放了操作人员，大幅降低劳动强度。
