Description

Technical Field

[0001] This utility model belongs to the technical field of aviation equipment, specifically relating to an oil receiving probe rod protected against lightning. Background Technology

[0002] The refueling probe is an indispensable component of an aerial refueling system, its primary function being to facilitate fuel transfer between the tanker and receiver aircraft during aerial refueling. Refueling probes are typically made of high-strength, corrosion-resistant materials to ensure they can withstand various complex environments and high-intensity operations. Structurally, refueling probes may be available in fixed, telescopic, or folding types to adapt to different aircraft models and operational requirements. Telescopic and folding refueling probes are particularly common in modern fighter jets; they can be retracted or folded when not in use to reduce wind resistance and radar cross-section, thus better maintaining the aircraft's stealth capabilities. To ensure the proper functioning and extend the service life of the refueling probe, regular maintenance and upkeep are required, including checking its structural integrity, cleanliness, and lubrication.

[0003] For example, existing Chinese patent CN214397268U discloses a lightning-proof refueling probe, which adopts a structure combining a composite reinforcing layer and a metal inner tube, reducing the weight of the metal while retaining high strength; at the same time, by setting up a lightning protection layer, it avoids the impact of lightning on in-flight refueling. However, the above solution only protects the refueling probe from lightning through the lightning protection layer, which is a single function and cannot provide other benefits to the refueling probe. During in-flight refueling, existing refueling probes inevitably experience friction when docking with the refueling cone sleeve, which easily generates static electricity. Static electricity is more likely to attract lightning, and since the refueling probe is made of metal, water vapor easily condenses on its outer surface at high altitudes, making it more conductive. Utility Model Content

[0004] The purpose of this invention is to provide an oil receiving probe rod that is protected against lightning strikes. It aims to reduce the generation of static electricity by setting up a pressing bladder and to achieve waterproof treatment of the oil receiving probe rod body by using a sliding mounting ring.

[0005] An oil receiving probe for lightning protection includes a mounting ring, an oil receiving probe body, and a limiting sleeve. The mounting ring is slidably fitted onto one end of the oil receiving probe body, and the limiting sleeve is fixedly fitted onto the other end. A cleaning mechanism is provided around the periphery of the mounting ring, comprising a liquid storage mechanism and a wiping ring. The wiping ring is installed on the inner side wall of the mounting ring for wiping the oil receiving probe body. A receiving groove is provided on the side of the mounting ring near the limiting sleeve, and the liquid storage mechanism is embedded inside the receiving groove, with its outlet located near the wiping ring. A liquid supply tank is provided on the other side of the mounting ring, and the liquid storage mechanism is connected to the liquid supply tank via a pipe. An inflatable bladder is provided around the periphery of the end of the oil receiving probe body near the limiting sleeve to reduce static electricity generation when the oil receiving probe body docks with the refueling cone sleeve, and to secure the docking of the oil receiving probe body with the refueling cone sleeve.

[0006] To better realize this utility model, the liquid storage mechanism further includes a liquid storage tank, a piston plate, and a wiping ring. A pressing bladder is provided on the side wall of the receiving groove, and a liquid storage tank is installed inside the receiving groove. A piston plate is slidably arranged inside the liquid storage tank. The pressing bladder is connected to one end of the liquid storage tank through a pipe and is used to drive the piston plate to slide by squeezing the pressing bladder. An outlet is provided at the other end of the liquid storage tank near the wiping ring. The liquid storage tank is connected to a liquid supply tank through a pipe.

[0007] To better realize this utility model, the liquid storage mechanism further includes a liquid storage tank, which is a flexible structure. The liquid outlet of the liquid storage tank is located near the wiping ring, so as to squeeze the liquid storage tank when the limiting sleeve slides into the receiving groove, so that the liquid inside the liquid storage tank overflows and soaks into the wiping ring.

[0008] To better realize this utility model, the mounting ring is further described as a heat-conducting ring.

[0009] To better realize this utility model, the liquid supply tank is further provided with lubricating oil.

[0010] To better realize this utility model, the outer side of the oil receiving probe body is further coated with a lightning protection coating.

[0011] The beneficial effects of this utility model are as follows: (1) This invention reduces static electricity generated when the oil receiving probe body docks with the refueling cone sleeve by using an inflatable bladder. Simultaneously, the inflatable bladder's internal compression makes the docking of the oil receiving probe body with the refueling cone sleeve more stable. This invention also utilizes a cleaning mechanism to remove moisture from the outer end of the oil receiving probe body, thereby effectively improving the lightning protection effect of the oil receiving probe body. Preferably, the outer end of the inflatable bladder is a smooth plane. The smooth plane design reduces friction on the outer surface of the inflatable bladder, thus reducing static electricity generation.

[0012] (2) The liquid storage tank of this utility model is fixedly connected inside the receiving tank, and a piston plate is slidably connected inside the liquid storage tank. A wiping ring is fixedly connected to the liquid outlet of the liquid storage tank, and the wiping ring is located on the outside of the oil receiving probe body. This utility model achieves better waterproofing by pushing the piston plate to squeeze out the liquid in the liquid storage tank, so that the liquid flows to the wiping ring and is evenly spread and coated on the outside of the oil receiving probe body, thus achieving better waterproofing and having better practicality.

[0013] (3) The mounting ring of this utility model is a heat-conducting ring, and the wiping ring abuts against the side wall of the mounting ring. The mounting ring can not only dissipate some heat, but also heat and dry the wiping ring by heating the mounting ring, so that the wiping ring can be used continuously and has good practicality. Preferably, the liquid supply tank of this utility model is filled with lubricating oil. The lubricating oil can not only facilitate the extension and sliding of the oil receiving probe body, but also form an oil film on the outer surface of the oil receiving probe body when the lubricating oil is applied to the outer end of the oil receiving probe body, which can greatly reduce the generation of water vapor. Secondly, the outer end of the oil receiving probe body of this utility model is coated with a lightning protection coating, which can directly and effectively protect the entire oil receiving probe body.

[0016] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Furthermore, the use of terms such as "horizontal" or "vertical" in the description of this utility model does not imply that the component is required to be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Example 1: An oil receiving probe for lightning protection includes an mounting ring 1, an oil receiving probe body 2, and a limiting sleeve 3. The mounting ring 1 is slidably fitted onto one end of the oil receiving probe body 2, and the limiting sleeve 3 is fixedly fitted onto the other end. A cleaning mechanism 6 is provided around the periphery of the mounting ring 1. The cleaning mechanism 6 includes a liquid storage mechanism and a wiping ring 63. The wiping ring 63 is installed on the inner side wall of the mounting ring 1 for wiping the oil receiving probe body 2. A receiving groove 4 is provided on the side of the mounting ring 1 near the limiting sleeve 3. The liquid storage mechanism is embedded inside the receiving groove 4, and its outlet is located near the wiping ring 63. A liquid supply tank 7 is provided on the other side of the mounting ring 1, and the liquid storage mechanism is connected to the liquid supply tank 7 via a pipe. An inflatable bladder 5 is provided around the end of the oil receiving probe body 2 near the limiting sleeve 3 to reduce static electricity generation when the oil receiving probe body 2 is connected to the refueling cone sleeve, and to stabilize the connection between the oil receiving probe body 2 and the refueling cone sleeve.

[0020] Preferably, the liquid storage mechanism includes a liquid storage tank 61, which is a flexible structure. The liquid outlet of the liquid storage tank 61 is located near the wiping ring 63, so as to squeeze the liquid storage tank 61 when the limiting sleeve 3 slides into the receiving groove 4, so that the liquid inside the liquid storage tank 61 overflows and soaks into the wiping ring 63.

[0021] This invention reduces static electricity generated when the oil receiving probe body 2 connects with the refueling cone sleeve via an inflatable bladder 5. The inflatable bladder 5 also provides internal compression to ensure a more stable connection between the oil receiving probe body 2 and the refueling cone sleeve. Furthermore, the cleaning mechanism 6 removes moisture from the outer end of the oil receiving probe body 2, effectively improving its lightning protection. Preferably, the outer end of the inflatable bladder 5 is a smooth plane. This smooth surface reduces friction on the outer surface of the inflatable bladder 5, thereby minimizing static electricity generation.

[0022] Example 2: A lightning-proof oil receiving probe, such as Figures 1-3 As shown, the device includes an installation ring 1, with an oil receiving probe body 2 slidably connected to the middle of the installation ring 1. A limiting sleeve 3 is fixedly connected to the outer end of the oil receiving probe body 2 away from the installation ring 1. A receiving groove 4 is opened at the end of the installation ring 1 near the limiting sleeve 3, and an inflatable bladder 5 is fixedly connected to the outer end of the oil receiving probe body 2 near the limiting sleeve 3. A cleaning mechanism 6 is fixedly connected inside the receiving groove 4. A liquid supply tank 7 is embedded at the end of the installation ring 1 away from the limiting sleeve 3. A pressing bladder 8 is fixedly connected to the inner wall of the receiving groove 4. Both the pressing bladder 8 and the liquid supply tank 7 are connected to the cleaning mechanism 6 through pipes. The liquid supply tank 7 provides liquid to the cleaning mechanism 6. When the oil receiving probe body 2 is docked with the refueling cone sleeve by the inflatable bladder 5, static electricity generation is reduced. At the same time, the inflation of the inflatable bladder 5 can also make the docking of the oil receiving probe body 2 more stable by internal compression when it docks with the refueling cone sleeve. Furthermore, the cleaning mechanism 6 can remove moisture from the outer end of the oil receiving probe body 2, thereby effectively improving the lightning protection effect of the oil receiving probe body 2.

[0023] Preferably, the cleaning mechanism 6 includes a liquid storage tank 61, a piston plate 62, and a wiping ring 63. The liquid storage tank 61 is fixedly connected to the inside of the receiving groove 4. The piston plate 62 is slidably connected inside the liquid storage tank 61. The wiping ring 63 is fixedly connected to the lower end of the liquid storage tank 61 and is located on the outside of the oil receiving probe body 2. The piston plate 62 pushes the liquid in the liquid storage tank 61 to be squeezed out, so that the liquid flows to the wiping ring 63 and spreads evenly, so that the wiping ring 63 applies the liquid to the outer end of the oil receiving probe body 2.

[0024] Preferably, the mounting ring 1 is a heat-conducting ring, and the wiping ring 63 abuts against the side wall of the mounting ring 1. The mounting ring 1 can not only dissipate some heat, but also heat and dry the wiping ring 63 by heating the heated mounting ring 1, so that the wiping ring 63 can be used continuously.

[0025] Preferably, the outer end of the oil receiving probe body 2 is coated with a lightning protection coating, which can directly and effectively protect the entire oil receiving probe body 2.

[0026] Preferably, the outer end of the airbag 5 is a smooth plane. By setting the smooth plane, less friction is generated on the outer surface of the airbag 5, thereby reducing the generation of static electricity.

[0027] Preferably, the liquid supply tank 7 is filled with lubricating oil. The lubricating oil not only facilitates the extension and sliding of the oil receiving probe body 2, but also forms an oil film on the outer surface of the oil receiving probe body 2 when the lubricating oil is applied to the outer end, which can greatly reduce the generation of water vapor.

[0028] During use, when the oil receiving probe body 2 is connected to the oiling cone sleeve, the air bladder 5 is inflated and inserted into the oiling cone sleeve. The inflated air bladder 5 makes the connection more stable. After oiling, when the oil receiving probe body 2 is retracted, the wiping ring 63 is used to wipe away the moisture on the outer end face of the oil receiving probe body 2. The limiting sleeve 3 enters the receiving groove 4 to squeeze the pressing bladder 8, so that the gas in the pressing bladder 8 enters the liquid storage tank 61 and pushes the piston plate 62. In this way, the piston plate 62 squeezes out the lubricating oil in the liquid storage tank 61 and absorbs it into the wiping ring 63. When the oil receiving probe body 2 extends again, the wiping ring 63 coats the outer end of the oil receiving probe body 2, which not only has a lubricating effect, but also forms an oil film on the outer end of the oil receiving probe body 2 to reduce the adhesion of water vapor. Compared with traditional lightning-proof oil receiving probes, this invention can reduce static electricity generation when the oil receiving probe body 2 is connected to the refueling cone sleeve via the inflatable bladder 5. At the same time, the inflation of the inflatable bladder 5 can also make the connection between the oil receiving probe body 2 and the refueling cone sleeve more stable by the internal compression. Furthermore, the cleaning mechanism 6 can remove moisture from the outer end of the oil receiving probe body 2, thereby effectively improving the lightning protection effect of the oil receiving probe body 2.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
