Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV refueling device. Background Technology

[0002] With the rapid development and widespread application of drone technology, it is playing an increasingly important role in various fields such as agricultural plant protection, power line inspection, geographic surveying, and emergency rescue. When drones perform long-duration, long-distance missions, they often need to refuel en route. To ensure operational efficiency, convenient and safe refueling equipment is needed that can be quickly deployed to the vicinity of the drone's take-off and landing point or the operation site to complete the refueling operation. Therefore, specialized drone refueling equipment with good mobility has emerged to meet the need for flexible and mobile support.

[0003] However, existing mobile drone refueling equipment still has some shortcomings in practical use. On the one hand, casters are usually installed at the bottom of the platform to facilitate equipment movement. However, during actual refueling operations, the equipment needs to remain stable to avoid shaking or even tipping over due to slight external forces or uneven ground, which would affect the safety of the refueling operation. On the other hand, to ensure operational stability, some equipment is equipped with fixing devices, but these fixing devices are often cumbersome to operate (such as requiring the use of additional pads or complex locking mechanisms), or require the casters to be fully retracted to contact the support surface, making the switching between mobile and fixed states inconvenient and inefficient. Utility Model Content

[0004] This invention provides a solution that can easily, quickly, and reliably switch between mobility and operational stability, especially during refueling operations, effectively avoiding the shaking problem caused by the casters contacting the ground.

[0005] The technical solution adopted by this utility model is as follows: a drone refueling device, including a mobile platform, a pusher fixedly connected to one end of the mobile platform, a side plate fixedly connected to the bottom of the pusher, an oil tank located on one side of the side plate on the mobile platform, an oil gun holder fixedly connected to one side of the oil tank, an opening at the top of the oil tank with an oil tank cover, a pump body located on one side of the oil tank on the mobile platform, an oil suction pipe connected to the oil outlet of the oil tank at the suction end of the pump body, a refueling pipe at the discharge end of the pump body, a refueling gun located in the oil gun holder at one end of the refueling pipe, and adjustable moving mechanisms at all four corners of the mobile platform.

[0006] As a further improvement of this utility model, two reinforcing rods located on one side of the push frame are fixedly connected to the mobile platform, and the two reinforcing rods are respectively located on both sides of the oil storage tank.

[0007] As a further improvement of this utility model, a transparent connecting pipe is provided on one side of the oil storage tank and the transparent connecting pipe is connected to the oil storage tank.

[0008] As a further improvement of this utility model, the adjustable moving mechanism includes a fixed base fixedly connected to the moving platform, a fixed plate fixedly connected inside the fixed base, a screw threadedly connected to the fixed plate, a knob fixedly connected to the top of the screw, a movable plate rotatably connected to the bottom of the screw and slidably connected to the fixed base, and a movable caster rotatably connected to the bottom of the movable plate.

[0009] As a further improvement of this utility model, the bottom end of the screw is rotatably connected to the movable plate via a bearing.

[0010] As a further improvement of this utility model, sliders are fixedly connected to both sides of the movable plate, and grooves for sliding sliders are provided on both sides of the fixed base.

[0011] The beneficial effects of this utility model are as follows: This utility model allows for easy, quick, and reliable adjustment of the height of the movable casters by rotating the knob, enabling free switching between the moving state (casters on the ground) and the stable working state (casters lifted off the ground, platform firmly supported).

Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0019] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This utility model provides the following: Figure 1-5 The unmanned aerial vehicle (UAV) refueling equipment shown includes a mobile platform (1), a pusher (2) fixedly connected to one end of the mobile platform (1), a side plate (3) fixedly connected to the bottom of the pusher (2), an oil tank (4) on one side of the side plate (3) on the mobile platform (1), an oil gun seat (5) fixedly connected to one side of the oil tank (4), an opening on the top of the oil tank (4) and an oil tank cover (6) at the opening, a pump body (7) on one side of the oil tank (4) on the mobile platform (1), an oil suction pipe (8) connected to the oil outlet of the oil tank (4) at the suction end of the pump body (7), a refueling pipe (9) at the discharge end of the pump body (7), a refueling gun (10) located in the oil gun seat (5) at one end of the refueling pipe (9), and an adjustable moving mechanism (11) at each of the four corners of the mobile platform (1).

[0022] like Figure 1-3As shown, the mobile platform (1) of this utility model is fixedly connected to two reinforcing rods (12) located on one side of the push frame (2), and the two reinforcing rods (12) are respectively located on both sides of the oil storage tank (4). The reinforcing rods (12) can enhance the connection strength between the push frame (2) and the mobile platform (1), so that the push frame (2) is more stable and less prone to shaking or deformation during the process of pushing the equipment to move. At the same time, the reinforcing rods (12) on both sides play a certain protective role for the oil storage tank (4) to prevent it from slipping.

[0023] like Figure 1 and Figure 3 As shown, the oil tank (4) in this utility model is provided with a transparent connecting pipe (13) on one side and the transparent connecting pipe (13) is connected to the oil tank (4). The oil level in the oil tank (4) can be observed intuitively through the transparent connecting pipe (13), which makes it convenient for operators to grasp the oil quantity information in a timely manner. When the oil level is low, it can be replenished in time to avoid insufficient fuel during the refueling operation and ensure the smooth progress of the drone refueling operation.

[0024] like Figure 5 As shown, the adjustable moving mechanism (11) of this utility model includes a fixed base (1101) fixedly connected to the moving platform (1), a fixed plate (1102) fixedly connected inside the fixed base (1101), a screw (1103) threadedly connected to the fixed plate (1102), a knob (1104) fixedly connected to the top of the screw (1103), a movable plate (1105) rotatably connected to the bottom of the screw (1103) and slidably connected to the fixed base (1101), a movable caster (1106) rotatably connected to the bottom of the movable plate (1105), a screw (1103) rotatably connected to the bottom of the screw (1103) through a bearing (1107), a slider (1108) fixedly connected to both sides of the movable plate (1105), and a sliding groove (1109) for the slider (1108) to slide on both sides of the fixed base (1101).

[0025] When the equipment needs to be moved, the operator simply turns the knob (1104) to rotate the screw (1103) on the fixed plate (1102), causing the movable plate (1105) to slide down along the slide groove (1109) until the movable caster (1106) contacts the ground and supports the mobile platform (1), at which point the equipment can be moved easily. When refueling is required at the work site, the knob (1104) is turned in the opposite direction, the screw (1103) rotates in the opposite direction, the movable plate (1105) slides upward, and the movable caster (1106) gradually lifts off the ground, so that the mobile platform (1) directly contacts the ground, achieving stable support and ensuring that the equipment will not be affected by the shaking of the caster (1106) during the refueling operation. This operation method is simple and fast. The operator does not need complicated tools or extra steps to complete the equipment status switching in a short time, which greatly improves work efficiency. Meanwhile, the rotating connection between the movable casters (1106) and the movable plate (1105) allows the equipment to steer flexibly during movement, further enhancing its mobility. Furthermore, during refueling operations, the movable casters (1106) are completely lifted off the ground, avoiding the impact of uneven ground or minor external forces on the equipment's stability. This provides a stable and reliable operating platform for drone refueling, ensuring the safety and smooth progress of the refueling operation.

[0026] Working Principle: In practical implementation, the operator first adjusts the adjustable moving mechanism by turning the knob, allowing the casters to contact the ground and lift the moving platform. This allows the operator to push the pusher to move the equipment to the drone refueling location. Upon arrival, the knob is turned again to lift the casters off the ground, ensuring the moving platform is in direct contact with the ground and the equipment is stable. Next, the fuel tank cap is opened to add fuel to the tank, and the fuel level is observed through the transparent connecting pipe. The pump is then started, drawing fuel from the tank through the suction pipe and delivering it to the refueling nozzle. The operator removes the refueling nozzle from its holder to refuel the drone. After refueling, the nozzle is returned to its holder, and the pump is turned off. To move the equipment to another location, the above steps of adjusting the adjustable moving mechanism are repeated, allowing the casters to contact the ground and lift the moving platform, then pushing the equipment to the new work site.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
