Description

Technical Field

[0001] This invention relates to the field of general aviation ground support equipment technology, specifically to a smart refueling skid-mounted device and system for general aviation aircraft. Background Technology

[0002] The intelligent refueling skid-mounted equipment and system for general aviation aircraft is an integrated refueling equipment in the field of general aviation ground support. Its main function is to provide safe, fast, accurate and traceable aviation fuel refueling services for general aviation aircraft.

[0003] Existing intelligent refueling skid-mounted equipment and systems for general aviation aircraft mainly involve filtering and stabilizing the fuel, then accurately metering it using a metering module, and finally refueling it through an explosion-proof refueling nozzle. The system collects data such as flow rate, pressure, temperature, and liquid level in real time and uploads it to a management platform for traceability and monitoring.

[0004] However, the above-mentioned equipment has certain shortcomings in use. Traditional small mobile refueling skid-mounted tanks are mostly single-cavity structures without damping and buffer structures. During the movement, start-up, and turning of the equipment, the fuel liquid sloshes violently, which can easily cause the center of gravity to shift and the vehicle body to sway and tilt. This not only results in poor driving stability but also easily causes fuel to impact the tank wall and violent fluctuations in oil and gas, posing safety hazards such as leakage and deflagration. In view of this, we propose an intelligent refueling skid-mounted equipment and system for general aviation aircraft. Summary of the Invention

[0005] The purpose of this invention is to provide a smart refueling skid-mounted device and system for general aviation aircraft to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A smart refueling skid-mounted device for general aviation aircraft includes a smart traveling chassis with casters at the bottom and a refueling assembly on the chassis.

[0014] In a further embodiment, the vertical rod and multiple sets of stirring paddles are arranged between multiple sets of long rods, the auger plate is arranged inside the guide tube, the circular hole is arranged above the guide tube, the guide groove is arranged below the guide tube, and the connection between the drain pipe and the oil tank is arranged inside the guide tube.

[0015] A smart refueling skid-mounted system for general aviation aircraft includes the aforementioned smart refueling skid-mounted equipment and a central control and coordination system. The central control and coordination system comprises a smart follow-up control module, a smart robotic arm control module, an explosion-proof pump control module, a safety protection module, and an automatic return and recharge module.

A servo motor 54 is fixedly installed on the oil tank 33, and a vertical rod 55 is fixedly installed at the output end of the servo motor 54. A stirring paddle 56 is fixedly installed on the vertical rod 55. A guide tube 57 is fixedly installed inside the oil tank 33. The guide tube 57 has a circular hole 58 and a guide groove 59. The vertical rod 55... The device is equipped with a fixed auger plate 510, a power motor 51, a long rod 52, a spherical paddle 53 and a stirring paddle 56 in multiple sets. The multiple sets of spherical paddles 53 are arranged in a cross pattern.

[0030] In this embodiment, before cleaning, the residual fuel in the oil tank 33 is emptied, and cleaning fluid is injected. The power motor 51 is started, driving the long rod 52 and the cross-arranged spherical paddles 53 to rotate at high speed, strongly disturbing the liquid in the tank, so that the sediment, impurities, and water at the bottom and dead corners of the tank are fully suspended and dispersed. At the same time, the servo motor 54 is started, driving the vertical rod 55, the stirring paddle 56 and the auger plate 510 to operate synchronously.

After the impurities are evenly dispersed, they are quickly discharged through the drain pipe 38, completing the thorough cleaning.

[0031] In an embodiment of the present invention, a smart refueling skid system for general aviation aircraft is also disclosed. This system includes the aforementioned smart refueling skid equipment for general aviation aircraft and a central control and coordination system. The central control and coordination system is composed of a smart follow-up control module, a smart robotic arm control module, an explosion-proof pump control module, a safety protection module, an automatic return and recharge module, and a tank 33 status monitoring module. The smart follow-up control module is equipped with an artificial intelligence recognition unit, used to automatically match authorized refueling personnel through biometrics. After receiving the start command from the refueling personnel, it drives the smart follow-up chassis 1 to automatically follow the refueling personnel at a safe distance of 2 meters, maintaining the same walking speed as the refueling personnel. Upon reaching the predetermined refueling position, it automatically recognizes the refueling personnel's hand gestures and controls the smart follow-up chassis 1 to stop walking, while simultaneously locking the bottom moving wheels 2. The smart robotic arm control module, after the equipment reaches the designated refueling position, controls the filling robotic arm to smoothly lift to a height of 1.2 meters above the ground according to the refueling personnel's hand gestures, providing assistance for the refueling personnel in completing the refueling process. The fuel refueling docking operation is completed. After refueling, the filling robot arm retracts and the equipment returns to its initial state according to the reset command. The explosion-proof pump oil control module is used to independently control the start and stop of the filling pump 310 and the opening and closing of the oil outlet electric valve. It collects and outputs fuel refueling flow data in real time through the flow meter to achieve accurate measurement and display of fuel refueling amount. The safety protection module integrates a self-sealing control unit, an electrostatic conduction unit, and a pressure regulation unit. It is used to trigger the automatic flow cut-off of the refueling nozzle when the aircraft fuel tank is full, through continuous electrostatic conduction. The line achieves equipotential connection between the fuel tank 33, the refueling nozzle, and the general aviation aircraft. At the same time, the breather valve and flame arrester on the top of the fuel tank 33 achieve pressure balance and fire and explosion protection inside the tank. The automatic return and refueling module is used to drive the intelligent accompanying chassis 1 back to the fuel dispensing position of the mother skid-mounted tank to refuel the fuel tank 33 according to gesture commands or automatic commands after the refueling operation is completed. After the small skid-mounted fuel tank 33 is filled with fuel, the intelligent accompanying chassis 1 is controlled to automatically travel to the predetermined charging point according to the preset path to realize the automatic docking and charging of the intelligent power supply system 35.

[0032] In this embodiment, the overall control and coordination system consists of six highly integrated modules: intelligent follow-up control, intelligent robotic arm control, explosion-proof pump control, safety protection, automatic return and recharging, and tank 33 status monitoring. Through an artificial intelligence recognition unit, it completes biometric matching verification of authorized personnel, driving the intelligent follow-up chassis 1 to automatically follow the operator while maintaining a 2-meter safe distance, enabling gesture-based start / stop and automatic locking of the moving wheels 2. Upon reaching the filling position, it controls the filling robotic arm to precisely lift to a 1.2-meter working height to provide lifting assistance, working in conjunction with the explosion-proof pump control module to achieve filling... The pump 310 features start / stop control, precise fuel metering, and data output. Simultaneously, through a safety protection module, it achieves self-sealing and flow interruption when full, electrostatic equipotential conduction, internal pressure balancing, and fire and explosion protection. After the refueling operation is completed, the chassis automatically returns to the mother skid-mounted tank position for refueling and travels to the designated area to complete the automatic docking and charging of the power supply system 35. Throughout the process, it works in conjunction with the oil tank 33 status monitoring module to achieve real-time monitoring and abnormal alarms for parameters such as oil level, temperature, and pressure. This enables intelligent, automated, and unmanned management of the entire equipment from following, refueling, safety protection to return to the site for recharging.

The smart follow-up control module is used to match the refueling personnel by biometrics, control the smart follow-up chassis (1) to maintain a safe distance and automatically follow the vehicle, and stop and lock the casters according to gesture commands. The smart robotic arm control module is used to control the lifting of the filling robotic arm according to gesture commands, and control the filling robotic arm to retract and reset after refueling. The explosion-proof pump control module is used to control the start and stop of the filling pump (310), the opening and closing of the oil outlet electric valve, and to measure the refueling amount through a flow meter. The safety protection module is used to achieve self-sealing when full, electrostatic equipotential connection, tank pressure regulation and spill protection. The automatic return and recharge module is used to control the smart follow-up chassis (1) to return to the mother skid-mounted tank for refueling after refueling, and automatically go to the charging point for automatic charging after refueling.
