[0002] Timely and accurate refueling of aircraft is an important part of ensuring flight safety. The role of refueling trucks is indispensable. Aircraft refueling trucks often move on the apron to refuel aircraft, but during refueling, the engine will generate huge heat and evaporate the substances in the engine into the air. Under air cooling, the oil gas re-condenses into oil droplets and finally falls on the apron.

[0003] In the prior art, the exhaust gas is usually discharged through the exhaust gas vent of the engine, and then allowed to cool with the air to eventually form oil droplets that fall on the apron.

[0013] The utility model proposes that the air hole is surrounded by the first slide groove of the air intake cylinder and the second slide groove on the card cover, and all the gas coming out of the air hole is introduced into the exchange ball through the air intake cylinder.

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 The utility model provides a technical solution: an aircraft refueling vehicle engine waste liquid collector, comprising: an exhaust pipe 1 and an air vent 2, the air vent 2 is arranged on the upper surface of the exhaust pipe 1, the air vent 2 is used to discharge the exhaust gas from the exhaust pipe 1, an air intake cylinder 5 is arranged on the upper surface of the exhaust pipe 1, the air intake cylinder 5 is the air inlet of the collecting device, one side of the air intake cylinder 5 is fixedly connected with an exchange ball 11, the exchange ball 11 is used to connect the collecting pipe 12, the exhaust pipe 1 and the heat dissipation cylinder 8, so that the gas between the three can be freely exchanged, and all the liquids in the three pipes will fall and be collected by the collecting barrel 13 In summary, a heat dissipation tube 8 and a collecting tube 12 are provided on one side of the heat exchange ball 11. Since the heat exchange tube and the collecting tube 12 are relatively inclined upward, the liquid inside them will flow into the collecting barrel 13 through the heat exchange ball 11. A heat dissipation head 9 is provided on the upper surface of the heat dissipation tube 8. The heat dissipation head 9 is used to plug in a plurality of heat dissipation micro-tubes 10. A plurality of heat dissipation micro-tubes 10 are provided on the upper surface of the heat dissipation head 9. The heat dissipation micro-tubes 10 can dissipate heat faster and more efficiently. The heat dissipation tube 8 and the air intake tube 5 are respectively inclined upward, and the lower end of the collecting tube 12 is fixedly connected to the collecting barrel 13, and the collecting barrel 13 is at the lowest end of all devices.

[0022] When in use, the exhaust gas is first input from the exhaust pipe 1 through the air vent 2 to the air inlet cylinder 5, and then the exhaust gas will enter the exchange ball 11. After passing through the exchange ball 11, the hot air will rise into the heat dissipation cylinder, and part of the gas after heat dissipation in the heat dissipation cylinder will cool into liquid and flow into the collection barrel 13 along the equipment.

[0023] Embodiment 2

[0024] See also Figure 2-Figure 3 On the basis of the first embodiment, a plurality of heat dissipation micro-tubes 10 are arranged at an angle. When the gas is sprayed from the micro-tube, due to the principle of action and reaction force, the heat dissipation head 9 will rotate under the action of the reaction force. The rotation of the heat dissipation head 9 will drive the heat dissipation tube 8 to rotate. A limiting ring 21 is fixedly installed at the bottom of the heat dissipation tube 8. A limiting groove 22 is arranged on the top of the exchange ball 11. The limiting ring 21 and the limiting groove 22 are rotatably connected. In this way, when the gas is sprayed from the heat dissipation micro-tube 10, the limiting ring 21 will rotate in the limiting groove 22. A plurality of heat dissipation copper sheets 7 are arranged on one side of the heat dissipation tube 8. The heat dissipation copper sheets 7 will be rapidly cooled by the surrounding air when rotating, so that the heat can be further dissipated.

[0025] When the gas is ejected from the heat dissipation micro-tube 10, the heat dissipation head 9 will drive the heat dissipation tube 8 to rotate under the reaction force, and the rotation of the heat dissipation tube 8 will drive the copper sheet on the heat dissipation tube 8 to rotate. At this time, the rotation of the copper sheet will further dissipate heat, effectively improving the heat dissipation efficiency of the heat dissipation tube 8, and the liquid generated by the heat dissipation of the heat dissipation tube 8 will flow back into the collection barrel 13, and the gas that still flies out of the device after dissipating heat through the heat dissipation tube 8 is not easily liquefied.

[0026] Embodiment 3

[0027] See also Figure 3-Figure 4 On the basis of the second embodiment, a symmetrical first through hole 6 is provided on one side of the air intake cylinder 5, and the first through hole 6 runs through the entire air intake cylinder 5. A symmetrical second through hole 15 is provided on one side of the air intake cylinder 5, and similarly, the second through hole 15 also runs through the entire air intake cylinder 5. A vertical cylinder 17 is fixedly installed between every two symmetrical first through holes 6, and the vertical cylinder 17 is installed between the through holes. A horizontal cylinder 16 is fixedly installed between every two symmetrical second through holes 15, and the horizontal cylinder 16 is also installed between the two second through holes 15. A plurality of vertical cylinders 17 and a plurality of horizontal cylinders 16 are vertically alternated in the air intake cylinder 5 to form a cooling net, and the mesh size thereof is relatively large, but has a better cooling effect. The vertical cylinder 17 and the horizontal cylinder 16 are fixedly installed between the two second through holes 15. The cylinders 16 are all configured to have a hollow structure, so that air can enter the horizontal cylinder 16 or the vertical cylinder 17 through the first through hole 6 and the second through hole 15. A first slide groove 18 is provided at one end of the air inlet cylinder 5, and an air vent 2 is slidably arranged in the first slide groove 18. A card cover 4 is provided at one end of the air inlet cylinder 5, and the card cover 4 is slidably connected to the air vent 2. A second slide groove 19 is provided at one end of the card cover 4, and the second slide groove 19 is slidably connected to the air vent 2. The first slide groove 18 and the second slide groove 19 can completely surround the air vent 2 together. A plurality of screws 3 are provided on the air inlet cylinder 5, and the card cover 4 is fixedly connected to the air inlet cylinder 5 by screws 3, and can be removed by screws 3 when cleaning is required.

[0028] In actual use, first, the exhaust gas is input from the exhaust pipe 1 to the air intake cylinder 5 through the air vent 2. At the bottom of the air intake cylinder 5, it will pass through a mesh heat dissipation structure composed of a relatively poor horizontal cylinder 16 and a vertical cylinder 17. In this process, part of the high-temperature gas is cooled and becomes liquid, and will flow into the exchange ball 11 along the equipment, and finally flow into the collecting barrel 13 for collection. Then the exhaust gas will enter the exchange ball 11. After passing through the exchange ball 11, the hot air will rise into the heat dissipation cylinder 8. After the gas is ejected from the heat dissipation microtube 10, the heat dissipation head 9 will drive the heat dissipation cylinder 8 to rotate under the reaction force, and the rotation of the heat dissipation cylinder 8 will drive the heat dissipation copper plate 7 on the heat dissipation cylinder 8 to rotate. At this time, the rotation of the heat dissipation copper plate 7 will further dissipate heat, effectively improving the heat dissipation efficiency of the heat dissipation cylinder 8, and the liquid generated by the heat dissipation of the heat dissipation cylinder 8 will flow back into the collecting barrel 13. The gas that still flies out of the device after heat dissipation through the heat dissipation cylinder 8 is not easy to be liquefied. Part of the gas after heat dissipation in the heat dissipation cylinder 8 will be cooled and become liquid and flow into the collecting barrel 13 along the equipment.
