Description

Technical Field

[0001] This invention relates to the field of aviation training technology, specifically to a training device for an aviation fuel pipeline system. Background Technology

[0002] Aviation fuel refers to a type of fuel specifically designed for aircraft. Its quality is higher than that used in heating systems and automobiles, and it typically contains various additives to reduce the risk of icing and explosion due to high temperatures. Aviation fuel is divided into two main categories: aviation gasoline, used in reciprocating engines, and aviation kerosene, used in aviation gas turbine engines and ramjet engines. Aviation fuel processing equipment is primarily aviation piston engines. Aviation piston engines operate on the same principle as regular automobile engines, only with higher power and lighter weight. Therefore, their quality requirements for aviation gasoline are similar to those for automotive gasoline. Currently, these engines are only used in some auxiliary aircraft, such as helicopters, communication aircraft, and weather aircraft, so the corresponding amount of aviation gasoline used has been greatly reduced.

[0003] Aviation fuel is usually transported by tanker trucks to parked aircraft or helicopters, but some airports have refueling stations where aircraft need to taxi to refuel, while some large airports have underground fuel pipelines connecting to each parking space, so aircraft only need to refuel via pump trucks.

[0004] There are two refueling methods: overwing and underwing. Overwing refueling is used on small aircraft, helicopters, and all reciprocating engine aircraft. One or more fuel tanks are opened and refueling is done using a conventional fuel pump, similar to refueling a car. Underwing refueling, also known as single-point refueling, is used on large aircraft that use aviation kerosene. A high-pressure hose is connected to the refueling port, and a fuel pump is used to pump the fuel into the tank at a pressure of 50 PSI. Since there is only one refueling point, the fuel distribution between the tanks is controlled by the refueling point control panel or the cockpit.

[0005] Currently, the skill requirements for aviation ground staff include targeted practical training to maintain their proficiency and improve their ability to handle emergencies, thereby enhancing their work capabilities. It is also necessary to standardize the actual refueling operations of ground staff. Most training methods rely on video tutorials and equipment models for demonstration and explanation. This teaching method slows down the learning progress of trainees. Furthermore, existing practical equipment lacks comprehensive testing functions during connection processes and cannot adequately meet user needs. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a training device for aviation fuel pipeline transportation systems. This solves the problem mentioned in the background that most general training methods rely on video illustrations and equipment models for demonstration and explanation, which reduces the learning progress of trainees. Furthermore, existing training equipment lacks comprehensive testing capabilities during the connection process.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a training device for an aviation fuel pipeline transportation system, including a training support frame, a training signal control box fixedly connected to the top of the training support frame, a pipeline socket fixedly connected to the bottom of the training signal control box, and a fuel pipeline connection mechanism fixedly connected to the training support frame located below the training signal control box.

[0008] The training signal control box includes a training signal box fixedly connected to the front end of the training bracket. The front of the training signal box is embedded with a timing screen, a buzzer, an alarm signal light group and an on / off signal light group. The buzzer is located below the timing screen. An alarm signal light group is arranged vertically on one side of the timing screen. An on / off signal light group is provided on the side of the alarm signal light group away from the timing screen.

[0009] Optionally, the alarm signal light group consists of multiple signal lights connected in parallel, wherein each signal light is electrically connected in series with an independent pressure sensor.

[0010] Optionally, the pressure sensors are located inside the training bracket, the oil pipeline connection mechanism, and the pipeline socket, respectively.

[0011] Optionally, the turn signal light group is composed of a green light and a red light, and both the green light and the red light are electrically connected in series with the timing screen.

[0012] Optionally, the timing screen, buzzer, and alarm signal light group are electrically connected in series.

[0013] Optionally, the training support includes a support plate, with both ends of the support plate fixedly connected to one side of the support plate, a pressure-bearing frame fixedly connected between the bottom ends of the support plate, the front of the support plate fixedly connected to one side of the angle iron, and a support buckle fixedly connected to the other side of the angle iron.

[0014] Optionally, the oil transfer connector mechanism includes a fixed insert tube inserted into the connector socket, a snap-fit ​​frame fixedly connected to the top end of the fixed insert tube, a connecting tube fixedly connected to the bottom end of the fixed insert tube, and a push handle sleeved on the outside of the connecting tube.

[0015] The bottom end of the connecting pipe is connected to a lifting frame by a thread. The inside of the lifting frame is provided with an oil delivery pipe that passes through the inside of the connecting pipe. Both sides of the lifting frame are movably connected to the lifting arm by hinge seats. The top of the lifting arm is provided with a limiting plate that is fixedly connected to the lifting frame. One end of the lifting arm is hinged to both sides of the lifting ring, and the lifting ring is fixedly sleeved on the outside of the oil delivery pipe.

[0016] Optionally, the edge of the buckle frame is provided with a positioning groove that matches the inside of the connector socket, and the buckle frame and the fixed insertion tube are designed as an integral structure.

[0017] Optionally, the oil delivery tube passes through the interior of the lifting ring, lifting frame, push handle, connecting tube, and fixed tube from bottom to top, and the central axes of the fixed tube, connecting tube, and push handle are aligned.

[0018] Optionally, the lifting arm and the limiting plate are symmetrically distributed about the central axis of the lifting frame.

[0019] This invention provides a training device for an aviation fuel pipeline transportation system, which has the following beneficial effects:

[0020] 1. This aviation fuel pipeline transportation system training equipment uses pressure sensors to monitor various points on the fuel pipeline connection mechanism in real time during training operations. When the pressure sensor is under insufficient pressure, it sends an electrical signal directly to the alarm signal light group. Multiple signal lights are connected in series with multiple pressure sensors, and the pressure status of each pressure sensor is indicated by the light of the signal lights, thereby judging the degree of closure of the fuel pipeline connection mechanism during training operations. At the same time as the signal light alarm, a buzzer also prompts the trainee to operate. The timing screen is connected in series with the opening and closing signal light group. When the green signal light is on, the timing screen starts timing, and when the red signal light is on, the timing screen stops timing, thereby timing and evaluating the training operation process.

[0021] 2. This aviation fuel pipeline transportation system training equipment uses a fixed insertion tube to achieve a fixed connection between the fuel pipeline mechanism and the pipeline socket through a snap-fit ​​rotation between the snap-fit ​​frame and the inside of the pipeline socket. The connection method is relatively convenient and quick, minimizing the time spent in the aviation fuel pipeline connection operation. The fuel pipeline is inserted into the inside of the pipeline socket by mechanical lifting. The lifting arm uses the hinge seat in the middle as a fulcrum. When the lifting arm rotates downward, it can raise the horizontal height of the lifting frame and the fuel pipeline. Attached Figure Description

[0046] Example 2

[0047] Please see Figures 1 to 7 The present invention provides a technical solution: a training device for an aviation fuel pipeline transportation system, including a training bracket 1, a training signal control box 2 fixedly connected to the top of the training bracket 1, a pipe socket 4 fixedly connected to the bottom of the training signal control box 2, and a fuel pipeline connection mechanism 3 fixedly connected to the training bracket 1 below the training signal control box 2.

[0049] Pressure sensors can monitor the oil pipeline connection mechanism 3 at various points in real time during the training operation. When the pressure sensor is under insufficient force, it will send an electrical signal directly to the alarm signal light group 204. Multiple signal lights are connected in series with multiple pressure sensors. The pressure status of each pressure sensor is indicated by the light of the signal lights, thereby judging the degree of closure of the oil pipeline connection mechanism 3 during the training operation. At the same time as the signal light alarm, the buzzer 203 will also prompt the trainee to operate. The timing screen 202 is connected in series with the opening and closing signal light group 205. When the green signal light is on, the timing screen 202 starts timing. When the red signal light is on, the timing screen 202 stops timing, thereby judging the timing of the training operation process.

[0050] The training support 1 includes a support plate 101. Both ends of the support plate 101 are fixedly connected to one side of the support plate 102. A pressure-bearing frame 103 is fixedly connected between the bottom ends of the support plate 102. The front of the support plate 101 is fixedly connected to one side of the angle iron 104.

[0051] The oil transfer connector mechanism 3 includes a fixed tube 301 inserted into the connector socket 4. A snap-fit ​​frame 302 is fixedly connected to the top of the fixed tube 301, and a connecting tube 303 is fixedly connected to the bottom of the fixed tube 301. A push handle 304 is sleeved on the outside of the connecting tube 303. A lifting frame 305 is threaded to the bottom of the connecting tube 303. An oil transfer tube 308 is provided inside the lifting frame 305 and passes through the inside of the connecting tube 303. Both sides of the lifting frame 305 are movably connected to the lifting arm 306 through hinge seats. A limiting plate 307 is fixedly connected to the top of the lifting arm 306 and is fixedly connected to the lifting frame 305. One end of the lifting arm 306 is hinged to both sides of the lifting ring 309, and the lifting ring 309 is fixedly sleeved on the outside of the oil transfer tube 308.

[0052] The edge of the snap-fit ​​frame 302 is provided with a positioning groove that matches the inside of the connector socket 4. The snap-fit ​​frame 302 and the fixed insertion tube 301 are integrated into one structure. The oil delivery tube 308 passes through the interior of the lifting ring 309, the lifting frame 305, the push handle 304, the connecting tube 303, and the fixed insertion tube 301 from bottom to top. The central axes of the fixed insertion tube 301, the connecting tube 303, and the push handle 304 are aligned.

When the lifting arm 306 rotates downward, it can raise the horizontal height of the lifting frame 305 and the fuel delivery tube 308.

[0054] In summary, when using this aviation fuel pipeline transportation system training equipment, the timing screen 202 is first reset to zero. During the trainee's training operation, the timing screen 202 is connected in series with the start / stop signal light group 205. When the green signal light is on, the timing screen 202 starts timing, and when the red signal light is on, the timing screen 202 stops timing. During the trainee's operation of connecting the fuel pipeline mechanism 3 and the pipeline socket 4, the pressure sensors at each position point are monitored in real time. When the pressure sensor is under insufficient pressure, an electrical signal is sent directly to the alarm signal light group 204. Multiple signal lights and multiple pressure sensors are connected in series and cooperate to realize the pressure status of each pressure sensor through the light indication of the signal lights. This allows the trainee to judge the degree of closure of the fuel pipeline mechanism 3 during the training operation. At the same time as the signal light alarm, the buzzer 203 will also prompt the trainee to operate.

[0055] The fixed insertion tube 301 achieves a fixed connection between the fuel delivery connection mechanism 3 and the connection socket 4 through the snap-fit ​​rotation between the snap-fit ​​frame 302 and the inside of the connection socket 4. The connection method is relatively convenient and quick, minimizing the time spent in the aviation fuel delivery connection operation. The fuel delivery tube 308 is inserted into the inside of the connection socket 4 by mechanical lifting. The lifting arm 306 uses the hinge seat in its middle as a fulcrum. When the lifting arm 306 rotates downward, it can raise the horizontal height of the lifting frame 305 and the fuel delivery tube 308.
