Description

Technical Field

[0001] This utility model relates to the field of refueling device technology, and in particular to a portable helicopter refueling device. Background Technology

[0002] A helicopter is an aircraft that relies on an engine to drive a rotor, generating lift and thrust to achieve vertical takeoff and landing, hovering, and various maneuvers. It possesses unique flight characteristics and a wide range of applications, playing a vital role in military, rescue, transportation, tourism, and many other fields. Refueling helicopters in the field or under unsupported conditions serves several purposes. First, it ensures the helicopter's continuous flight capability, enabling it to successfully complete missions such as reconnaissance, patrol, and transportation in military operations, as well as rapid arrival at disaster sites and extended operations during rescue operations. Second, it ensures that helicopters have a sufficient fuel supply even in remote areas far from fixed refueling facilities or in emergency situations, maintaining normal flight functions and flight safety. Through refueling devices that interface with external fuel sources, helicopters can be refueled promptly and effectively, ensuring efficient operation and mission execution in various complex environments.

[0003] However, existing helicopter refueling devices often have low refueling efficiency, with a limited amount of fuel that can be refueled per unit time, resulting in excessively long refueling times. Simultaneously, fuel loss is a significant issue; leaks and evaporation occur during refueling, wasting valuable fuel and increasing operating costs and resource consumption. Furthermore, these refueling devices are quite cumbersome to operate. From connecting to the external fuel source and setting fuel delivery parameters to the actual refueling operation and post-refueling cleanup and inspection, all require strict adherence to complex procedures. This series of complex operations greatly increases the workload of personnel, requiring prolonged concentration and careful operation, easily leading to fatigue and negatively impacting the quality and safety of refueling. Therefore, to address these shortcomings, a portable helicopter refueling device is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable helicopter refueling device, which aims to improve the problems of low refueling efficiency and complicated operation procedures of some existing helicopter refueling devices.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A portable helicopter refueling device includes a support frame, a diesel engine pump assembly installed inside the support frame, a filter fixedly connected to the rear side of the inside of the support frame, a top frame detachably connected to the top of the support frame, a hose reel fixedly connected to the front side of the top frame, a self-sealing fuel gun fixedly connected to the front right end of the support frame, an oil inlet on the right side of the support frame, and an oil outlet on the top of the support frame.

[0007] As a further description of the above technical solution:

[0008] The top frame is fixedly connected to two folding handles, the support frame is fixedly connected to two folding handles, and the bottom four corners of the support frame are fixedly connected to casters.

[0009] As a further description of the above technical solution:

[0010] A hose is provided on the outside of the hose reel, and an oil receiving device is connected to the output end of the self-sealing oil gun.

[0011] As a further description of the above technical solution:

[0012] The support frame is equipped with an electrostatic grounding clamp, and the hose is 6 meters long.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the entire device is compact and small in structure. After the upper and lower parts are combined and fixed, it can be pushed by a single person on solid ground. This refueling device can be manually lifted onto or unloaded from a helicopter and carried to the refueling location. The refueling device is easy to operate, and the refueling process can be automatically controlled by a self-sealing nozzle and feedback system—when the nozzle is fully open, the engine automatically increases speed and maintains its rated speed; when the nozzle is closed (or the nozzle is filled to the brim and self-sealed), the engine automatically drops to idle speed, and the fuel pump stops. The device has its own battery and electric starter, allowing the engine to start normally in low temperatures. The device is small and lightweight, has no special requirements for the operating site, and is highly adaptable to various environments. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1 to 3 This utility model provides an embodiment of a portable helicopter refueling device, including a support frame (1), which provides a stable mounting position and support for other structures. A diesel engine pump assembly (2) is installed inside the support frame (1), which is the power core of the refueling device. It generates power by consuming diesel fuel to drive the pump, thereby providing the necessary pressure for oil delivery. A filter (3) is fixedly connected to the rear side of the inside of the support frame (1). The filter (3) can effectively remove impurities, particles, and other foreign matter from the oil, ensuring that the purity of the oil entering the helicopter meets the requirements. The top of the support frame (1) is detachably connected to a top frame (4). A hose reel (5) is fixedly connected to the front side of the top frame (4). A hose with a length of 6 meters is installed on the outside of the hose reel (5). A self-sealing oil gun (6) is fixedly connected to the front right end of the support frame (1). The output end of the self-sealing oil gun (6) is connected to an oil receiving device. When refueling, the hose reel (5) is opened, and the hose can be smoothly released from the reel and then connected to the pump inlet and the self-sealing oil gun (6) to form a complete oil delivery path. After refueling, the hose can be put back into the hose reel (5). This retractable function of the hose reel (5) ensures the orderly use of the hose and proper storage when not in use, avoiding wear and compression of the hose due to random placement.

[0022] Reference Figures 1 to 3The support frame (1) has an oil inlet (7) on its right side, which provides oil to the refueling device. The support frame (1) has an oil outlet (8) on its top. When the diesel engine pump set (2) is working, the oil enters the hose through the oil outlet (8) under pressure, and then is delivered to the receiving equipment through the hose and the self-sealing oil gun (6). The top frame (4) has two fixed folding handles (9) on its exterior, and the support frame (1) has two fixed folding handles (10) on its exterior. When the refueling device needs to be moved to a suitable refueling position, the operator can push or pull the device by holding the folding handles (10). With the help of the casters (11) at the bottom, the device can move smoothly on the ground. When not in use, the folding handles (10) can be folded up to make the device look neater. The support frame (1) is fixedly connected to four corners of its bottom with casters (11). An electrostatic grounding clamp is installed inside the support frame (1). During refueling, static electricity is generated when the oil flows within the device and is transferred between the hose and the receiving equipment. If this static electricity is not promptly dissipated, it can accumulate to a certain level and cause serious safety accidents such as fires or explosions. The electrostatic grounding clamp, through a good conductive connection with the ground, can promptly conduct the static electricity generated during refueling to the ground, eliminating the potential for static electricity hazards and ensuring that the entire refueling process is carried out in a safe environment, thereby protecting the safety of the helicopter, the refueling device, and the surrounding environment.

[0023] Working principle: During refueling, move the device to a suitable position using the casters 11, open the hose reel 5 and connect the pump inlet hose, insert the fuel nozzle into the receiving equipment port, connect the static grounding clamp, manually start the engine, and turn on the fuel nozzle switch. The diesel engine pump unit 2 will operate, and fuel will enter through the inlet 7, be filtered by the filter 3, and then be delivered to the receiving equipment through the outlet 8, hose, and fuel nozzle. After refueling, turn off the engine and fuel nozzle, retract the fuel nozzle and hose into the hose reel 5, disconnect the pump inlet hose, retract the static grounding clamp, and return the refueling reel to its original position.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
