Technical Field
[0001] This utility model relates to an oil temperature sensing and regulating device for aircraft refueling trucks, belonging to the technical field of temperature sensing and regulating devices. Background Technology
[0002] In the field of air transport, aircraft refueling trucks are core special vehicles ensuring aircraft fuel supply, and their stable operation is directly related to the normal takeoff and landing and flight safety. Among them, tank refueling trucks, with their large-capacity storage tanks, can achieve independent storage and efficient transportation of aviation fuel, becoming a key link in the airport ground fuel support system.
[0003] However, due to the design limitations of large-capacity fuel tanks, current aircraft refueling trucks are generally bulky. In open-air parking environments at airports, especially during the high temperatures of summer, these trucks are exposed to direct sunlight for extended periods. The black metal tanks of the fuel tanks act as efficient heat absorbers, rapidly absorbing large amounts of solar radiation. Actual measurements show that after four hours of continuous sunlight exposure, the surface temperature of the fuel tank can soar to over 65°C, and the internal fuel temperature also rises accordingly. This high-temperature environment significantly increases the volatility of aviation fuel. Studies indicate that for every 10°C increase in fuel temperature, the evaporation rate can increase by 20%-30%. This not only causes unnecessary waste of fuel resources, but more seriously, the accumulation of evaporating fuel vapors inside the sealed tank can cause a rapid increase in pressure. When the pressure exceeds the tank's tolerance limit, it can easily lead to major safety accidents such as tank deformation, rupture, or even explosion, posing a significant threat to airport facilities, personnel safety, and air transport order.
[0004] To mitigate the aforementioned risks, the industry currently employs a common strategy of manual, timed cooling, such as manually spraying cooling water and laying insulating mats. However, this traditional manual intervention method has several drawbacks: First, it requires a significant investment of manpower for periodic inspections and cooling operations, substantially increasing operating costs. Second, manual inspections are time-sensitive, making it difficult to respond promptly to sudden high-temperature anomalies, often resulting in delayed cooling measures and ineffective control of the tank's temperature. Third, manual operations lack standardized procedures and precise control methods, and the cooling effect is greatly affected by factors such as operator experience and weather conditions, making it difficult to guarantee the stability and continuity of the cooling process. With increasingly stringent requirements for the efficiency and safety of ground support operations in the aviation transportation industry, traditional manual cooling methods are no longer sufficient to meet the operational needs of modern aviation support systems. There is an urgent need to develop intelligent and automated oil tank cooling technologies to improve the safety and reliability of aircraft refueling truck operations. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4As shown, an aircraft refueling truck oil temperature sensing and regulating device includes a mounting rail 1. Clamping structures 2 are provided at both ends of the mounting rail 1 to securely install the entire aircraft refueling truck oil temperature sensing and regulating device at specific positions on the aircraft refueling truck. Temperature sensor controllers 3 are installed on the lower surfaces of both ends of the mounting rail 1 to sense the ambient temperature around the aircraft refueling truck's fuel tank or fuel line in real time. An electric retractor 4 is designed at one end of the mounting rail 1 to control the raising and lowering of a shade cloth 5. The shade cloth 5 is fitted onto the outside of the electric retractor 4, and its main function is to block direct sunlight from hitting the aircraft refueling truck's fuel tank or fuel line, reducing solar radiation. The heat generated by the radiation reduces the rate of oil temperature rise, thus providing some protection for the oil tank and oil circuit. Tension structures 6 are installed inside both sides of the mounting rail 1, primarily to provide space for the shading cloth 5 to extend and retract. Connecting sleeves 7 are fitted onto the outer side of the tension structure 6, connecting the shading cloth 5 to the tension structure 6 as a whole, allowing the shading cloth 5 to extend or retract with the movement of the tension structure 6, ensuring the normal operation of the shading cloth 5. The connecting sleeves 7 and the shading cloth 5 are fixedly connected to each other. A cooling guide pipe 8 is rotatably installed inside the tension structure 6, its function being to transport the cooling medium.
[0020] The clamping structure 2 includes a clamping fixing plate 201. A rotating connection hole is provided on one side of the clamping fixing plate 201, and an adjusting threaded rod 202 is rotatably engaged inside the rotating connection hole. A limit sliding rod 203 is fixedly welded to the other side of the clamping fixing plate 201. Both ends of the mounting guide rail 1 are designed with connecting operation blocks. An adjusting threaded hole is provided on one side of the connecting operation block, and the adjusting threaded rod 202 is threadedly connected to the adjusting threaded hole. A connecting limit hole is provided on the other side of the connecting operation block, and the limit sliding rod 203 is slidably engaged with the connecting limit hole, thereby clamping... The clamping plate 201 is placed on the mounting part of the aircraft refueling truck, so that one side of the clamping plate 201 is in contact with the mounting part. The adjusting thread rod 202 is rotated using a wrench or other tools. The adjusting thread rod 202 rotates in the adjusting thread hole, which at the same time drives the clamping plate 201 to move. When the clamping plate 201 is in close contact with the mounting part and the appropriate clamping force is achieved, the rotation of the adjusting thread rod 202 is stopped. At this time, the clamping structure 2 is fixedly connected to the mounting guide rail 1, and the entire aircraft refueling truck oil temperature sensing and adjustment device is stably installed on the aircraft refueling truck.
[0021] The stretching structure 6 includes a positioning rack 601, which is fixedly installed on both sides of the mounting guide rail 1. A translation limit block 602 is slidably engaged inside the mounting guide rail 1. A translation gear 603 is rotatably engaged inside the translation limit block 602. The translation gear 603 meshes with the positioning rack 601. A stretching motor 604 is fixedly installed on the outside of the translation limit block 602. The output end of the stretching motor 604 is fixedly connected to the translation gear 603. A linkage stretching tube 605 is fixedly welded between the translation gears 603. Output communication holes are evenly opened on the outside of the linkage stretching tube 605. When the stretching structure 6 needs to be unfolded to cool the fuel tank or fuel line of the aircraft refueling truck, the stretching motor 604 is started. The stretching motor 604 outputs torque to drive the translation gear 603 to rotate. The translation gear 603 meshes with the positioning rack 601, converting the rotational motion into translational motion. This causes the translation limit block 602 and the linkage stretching tube 605 to move on the mounting guide rail 1. As the translation gear 603 rotates, the linkage stretching tube 605 gradually unfolds, and the output connecting hole gradually approaches the part that needs to be cooled. When the linkage stretching tube 605 is stretched to the appropriate position, the rotation of the stretching motor 604 stops. At this time, the output connecting hole is in close contact with the part that needs to be cooled, and the cooling medium can be output through the output connecting hole for heat exchange and cooling.
[0022] The connecting sleeve 7 is rotatably fitted onto the outside of the linkage stretching tube 605. A material output hole is provided on the lower side of the connecting sleeve 7. The cooling guide tube 8 is rotatably snapped into the inside of the linkage stretching tube 605. A cooling discharge hole is designed on the lower side of the cooling guide tube 8. One end of the cooling guide tube 8 is fixedly connected to the external input structure. The connecting sleeve 7 is rotatably fitted onto the outside of the linkage stretching tube 605, ensuring that the connecting sleeve 7 can rotate flexibly. Simultaneously, the cooling guide tube 8 is rotatably snapped into the inside of the linkage stretching tube 605, and one end of the cooling guide tube 8 is... The device is fixedly connected to the external input structure to complete the basic installation of the entire device. The external input structure is opened to input the cooling medium into the cooling guide pipe 8. The cooling medium flows in the cooling guide pipe 8 and flows out through the cooling discharge hole, where it exchanges heat with the fuel tank or fuel line of the aircraft refueling truck to reduce the oil temperature. When it is necessary to adjust the cooling range, the linkage tension pipe 605 can be moved by the tension structure 6. The connecting sleeve 7 and the cooling guide pipe 8 will also move accordingly, thereby changing the position of the cooling discharge hole and the material output hole to achieve the adjustment of the cooling range.
