Description

Technical Field

[0001] The utility model relates to the technical field of sewage suction vehicles, in particular to a real-time water volume metering device for sewage suction vehicles. Background Art

[0002] The sewage suction truck uses a vacuum pump to discharge or inhale air to create a positive or negative pressure environment to achieve normal operation such as suction and discharge of sewage. Due to its sealing characteristics during operation, it is necessary to install a liquid level meter on the outside of the tank to measure the real-time water volume of the sewage suction truck, so as to remind the operator to turn off the vacuum pump in time when the tank is full to avoid danger. After searching: Patent No. CN111350266A is a sewage suction truck with an intelligent overflow prevention system and its control method. The sewage suction truck includes an electronic control system, a second-class chassis, a tank body, a vacuum system, an intelligent overflow prevention system, a sewage suction pipe and a sewage discharge pipe. The height of the medium liquid level in the tank is monitored in real time. When the tank reaches the full calibration value, the switch signal is triggered by the liquid level monitoring device, the tank top door pump cylinder is connected to control the four-way valve reversing, automatic unloading is achieved, and an alarm is sounded to remind, so as to solve the problem that the existing sewage suction truck overflow prevention system can only rely on mechanical seals, and the vacuum suction force cannot be turned off in time, and liquid sewage is easily sucked into the pipeline assembly, the filtration system, and the power system, resulting in high maintenance costs and even damage to the system.

[0003] However, in actual use, the liquid absorbed by the sewage suction truck is relatively dirty and the sewage is relatively viscous, so that sewage, sludge and other debris are easily attached to the inner surface of the liquid level meter or block the liquid level meter, making the measurement function of the liquid level meter invalid, and unable to accurately and real-time measure the water volume of the sewage suction truck, and overflow is prone to occur. At the same time, after long-term use, a large amount of dust will adhere to the surface of the liquid level meter display panel used to display the scale. If it is not cleaned in time, it will easily affect the accurate viewing of personnel. Therefore, we propose a real-time water volume metering device for sewage suction trucks to solve the above problems. Utility Model Content

At the same time, the surface of the display panel can be cleaned to ensure the cleanliness of the display panel surface, which is conducive to accurate viewing by personnel.
