Description

Technical Field

[0001] This utility model relates to the technical field of de-icing fluid filling process for aircraft de-icing trucks, specifically to a de-icing fluid and anti-icing fluid filling system for aircraft de-icing trucks. Background Technology

[0002] Aircraft de-icing trucks are essential equipment for removing ice and snow from aircraft surfaces. In winter or low-temperature environments, ice or snow may accumulate on aircraft surfaces, affecting their aerodynamic performance and even jeopardizing flight safety. Therefore, the role of aircraft de-icing trucks is crucial. Currently, aircraft de-icing trucks manufactured domestically and internationally are equipped with de-icing fluid reservoirs (Type I liquid ethylene glycol) and anti-icing fluid reservoirs (Type II propylene glycol). At domestic airports, de-icing fluid and anti-icing fluid are typically added through the filling ports on the top of these reservoirs. When adding de-icing fluid and anti-icing fluid via the top-mounted filler port, depending on the vehicle model, it is necessary to either pour the fluid into or drive into the filling area of ​​the refueling station. Ensure the top-mounted filler port is below the water condenser outlet of the refueling station. Two workers (one operator and one support staff) then climb a ladder along the side of the vehicle to the top, open the filler cap, and place the water condenser outlet pipe into the filler port to add fluid. The support staff, following instructions from the other operator, manually controls the refueling station's gear pump by operating the start / stop button on the electrical panel. This raises the following issues: Operators face significant safety risks working at heights in winter rain and snow; the support staff's manual operation of the gear pump's start / stop button on the electrical panel, based on operator instructions, affects the timeliness of communication and coordination between the two parties, impacting the accuracy of pump shutdown and fluid addition. This results in fluid spillage during de-icing fluid addition, causing waste and environmental pollution. Utility Model Content
