Abstract
Description
Technical Field
[0001] This application relates to the field of target drone fuel tanks, and more particularly to a target drone inverted flight fuel supply device. Background Technology
[0002] Target drones are unmanned aerial vehicles used for military shooting training. By controlling the flight path of the target drone, complex enemy aircraft flight trajectories can be simulated for shooting training. During flight, target drones typically perform various high-difficulty maneuvers, thereby increasing the difficulty for pilots when aiming and achieving the training objective.
[0003] The existing target drone's fuel tank is connected to the engine via a fuel line, and the engine draws fuel from the tank through the fuel line. The fuel line is connected to the bottom of the fuel tank, and during flight, fuel flows into the engine through a fuel filler hole at the bottom of the tank, enabling the engine to provide thrust to the target drone.
[0004] The aforementioned technical solutions have the following drawbacks: during the flight of the target drone, when it flies upside down, the fuel in the fuel tank is located at the top of the fuel tank, making it difficult for the fuel line to draw fuel from the tank. Utility Model Content
[0005] In order to enable the target drone to stably draw fuel from the fuel tank when flying inverted, this application provides a fuel supply device for target drones flying inverted.
[0006] The target drone inverted flight fuel supply device provided in this application adopts the following technical solution:
[0007] A target drone inverted flight fuel supply device includes a fuel tank, a fuel outlet pipe, two connecting mechanisms, a sliding mechanism, and a fuel supply pipe. The two ends of the fuel outlet pipe are respectively connected to the opposite side walls of the fuel tank. The two connecting mechanisms are respectively installed on opposite sides of the fuel outlet pipe. The sliding mechanism is connected to the end of the fuel supply pipe and is used to drive the fuel supply pipe to slide and connect with the two connecting mechanisms respectively.
[0008] By adopting the above technical solution, and by setting a fuel outlet pipe on the fuel tank, the fuel in the fuel tank can flow out from the bottom and top of the fuel tank respectively when the target drone is flying forward and backward. By setting two connecting mechanisms on the fuel outlet pipe, the fuel in the fuel outlet pipe can flow out from the two connecting mechanisms respectively. The fuel supply pipe slides through a sliding mechanism. When the target drone is flying backward, the fuel in the fuel tank is located at the top of the fuel tank. At this time, the fuel supply pipe can slide through the sliding mechanism to connect with the connecting mechanism located at the top of the fuel tank. At this time, the engine can draw fuel from the top of the fuel tank, thereby stabilizing the power of the target drone during flight.
[0009] Optionally, the oil outlet pipe includes two connecting parts and a vertical part, with both ends of the vertical part connected to the two connecting parts respectively, and the end of the connecting part away from the vertical part connected to the oil tank.
[0010] By adopting the above technical solution, by setting connecting parts at both ends of the vertical part, the fuel in the tank can flow out through the connecting parts, thereby making the cross-section of the connecting parts smaller. When fuel enters the connecting parts, the air in the connecting parts can be quickly squeezed out, so that the engine can quickly draw fuel and reduce the chance of engine stalling.
[0011] Optionally, the connecting part is configured as an inclined tube, and the angle between the connecting part and the vertical part is an acute angle.
[0012] By adopting the above technical solution, and by setting the connecting part as an inclined tube, when there is fuel in the oil outlet pipe and the oil supply pipe has not yet been connected to the connecting mechanism that needs to be connected, the fuel can accumulate at the connection between the connecting part and the vertical part, reducing the probability of the fuel in the oil outlet pipe flowing out from the connecting mechanism, thereby reducing the probability of fuel leaking from the oil outlet pipe into the target machine.
[0013] Optionally, the connecting mechanism includes a connecting pipe and a solenoid valve. One end of the connecting pipe is connected to the oil outlet pipe, and the solenoid valve is installed on the connecting pipe. The solenoid valve is used to control the opening and closing of the connecting pipe.
[0014] By adopting the above technical solution, and by installing a solenoid valve on the connecting pipe, the solenoid valve can control the opening and closing of the connecting pipe, thereby reducing the probability of fuel leakage in the fuel tank. When the target drone is flying forward and backward, the solenoid valves at the lower and upper ends of the fuel tank will be activated respectively, so that fuel can always flow into the fuel supply pipe through the connecting mechanism.
[0015] Optionally, the sliding mechanism includes a slide rail and a slider. The slide rail is vertically fixed to the outside of the oil outlet pipe, and the slider is slidably connected in the slide rail. A connecting hole is provided on the slider, and one end of the oil supply pipe is connected to the connecting hole. When the slider slides to the end of the slide rail, it is connected to the connecting pipe.
[0016] By adopting the above technical solution, the slider is slidably connected to the slide rail, allowing the slider to slide on the slide rail under the action of gravity. Thus, when the target drone is flying forward and backward, the slider can slide to the same side as the fuel in the fuel tank under the action of gravity. At this time, the slider drives the fuel supply pipe to move, thereby connecting the fuel supply pipe with different communication mechanisms in the fuel tank.
[0017] Optionally, a contact switch is provided at the end of the slide rail, and the slider is used to slide in the slide rail and contact the contact switch, which is used to control the on / off state of the solenoid valve.
[0018] By adopting the above technical solution, a contact switch is set at the end of the slide rail, which can control the opening and closing of the solenoid valve. When the slider moves to the end of the slide rail, the slider contacts the contact switch at the end of the slide rail. At this time, the solenoid valve on the same side as the slider opens, and fuel can flow into the fuel supply pipe through the connecting pipe, further reducing the probability of fuel leakage from the connecting pipe.
[0019] Optionally, electromagnets are provided at both ends of the slide rail, and the electromagnets are used to magnetically connect with the slider.
[0020] By adopting the above technical solution, an electromagnet is installed at the end of the slide rail, which can be magnetically connected to the slider. When the slider slides in the middle of the slide rail, the electromagnet can apply a magnetic force to the slider, thereby increasing the probability of the slider sliding to the end of the slide rail. When the slider slides to the end of the slide rail, the slider and the electromagnet contact and connect with each other, thereby improving the stability of the connection between the slider and the connecting pipe, reducing the probability of slider vibration and fuel leakage.
[0021] Optionally, a controller is connected to the electromagnet, and a gravity sensor is connected to the input terminal of the controller. The gravity sensor is used to detect the acceleration direction of the target machine, and the controller is used to control the operation and power-off of the electromagnet.
[0022] By adopting the above technical solution, by setting a controller on the electromagnet, the controller can receive the electrical signal of the gravity sensor in real time. The gravity sensor can detect the direction of the gravitational acceleration of the target machine. When the acceleration direction is upward, the fuel in the tank and the slider both move upward. At this time, the controller can control the electromagnet located above the slide rail to be energized, so that the slider can quickly slide to the top of the slide rail and connect with the communication mechanism on the upper side of the tank.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By installing a fuel outlet pipe on the fuel tank, the fuel in the tank can flow out from the bottom and top of the tank respectively when the target drone is flying forward and backward. By installing two connecting mechanisms on the fuel outlet pipe, the fuel in the fuel outlet pipe can flow out from the two connecting mechanisms respectively. The fuel supply pipe slides through a sliding mechanism. When the target drone is flying backward, the fuel in the tank is located at the top of the tank. At this time, the fuel supply pipe can slide through the sliding mechanism to connect with the connecting mechanism located at the top of the tank. At this time, the engine can draw fuel from the top of the tank, thereby stabilizing the power of the target drone during flight.
[0025] 2. By installing a solenoid valve on the connecting pipe, the solenoid valve can control the opening and closing of the connecting pipe, thereby reducing the probability of fuel leakage in the fuel tank. When the target drone is flying forward and backward, the solenoid valves at the lower and upper ends of the fuel tank will be activated respectively, so that fuel can always flow into the fuel supply pipe through the connecting mechanism.
[0026] 3. By setting a controller on the electromagnet, the controller can receive the electrical signal from the gravity sensor in real time. The gravity sensor can detect the direction of the gravitational acceleration of the target machine. When the acceleration direction is upward, the fuel in the tank and the slider both move upward. At this time, the controller can control the electromagnet located above the slide rail to be energized, so that the slider can quickly slide to the top of the slide rail and connect with the communication mechanism on the upper side of the tank.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.
[0033] This application discloses a target drone inverted flight fuel supply device, referring to... Figure 1 and Figure 2 The system includes a fuel tank 1, a fuel outlet pipe 2, two connecting mechanisms 3, a sliding mechanism 4, and a fuel supply pipe 5. The fuel tank 1 stores fuel. The fuel outlet pipe 2 is connected to the top and bottom of the fuel tank 1, respectively. The connecting mechanisms 3 are connected to the fuel outlet pipe 2, and the two connecting mechanisms 3 are located at the upper and lower ends of the fuel outlet pipe 2, respectively. The sliding mechanism 4 is connected to the fuel supply pipe 5, which is a flexible hose. The sliding mechanism 4 drives the fuel supply pipe 5 to slide back and forth in the vertical direction, so that the fuel supply pipe 5 can connect to the two connecting mechanisms 3 and draw fuel from the fuel tank 1. During the flight of the target drone, the engine draws fuel from the bottom of the fuel tank 1 through the fuel supply pipe 5. When the target drone flies upside down, the fuel in the fuel tank 1 accumulates at the top of the fuel tank 1 due to gravity. At this time, the sliding mechanism 4 can drive the end of the fuel supply pipe 5 to slide, so that the fuel supply pipe 5 can connect to the connecting mechanism 3 located at the top of the fuel tank 1. At this time, the engine can draw fuel from the top of the fuel tank 1, thus stabilizing the power of the target drone during flight.
[0034] Reference Figure 1 The oil outlet pipe 2 includes two connecting parts 21 and a vertical part 22. The two connecting parts 21 are horizontally arranged, and the vertical part 22 is vertically arranged. Both ends of the vertical part 22 are connected to the ends of the connecting parts 21, respectively. The oil outlet pipe 2 can be made of a bent square tube. The two connecting parts 21 are respectively connected to the top and bottom of the oil tank 1. Two oil holes 23 are opened on the vertical part 22, which are respectively opened at the bottom and top of the oil outlet pipe 2. Each oil hole 23 is connected to a connecting mechanism 3.
[0035] Reference Figure 1 and Figure 2 The connecting mechanism 3 includes a connecting pipe 31 and a solenoid valve 32. One end of the connecting pipe 31 is connected to the oil hole 23, and the solenoid valve 32 is installed on the connecting pipe 31. The solenoid valve 32 is used to control the opening and closing of the connecting pipe 31.
[0036] Reference Figure 3 The sliding mechanism 4 includes a slide rail 41 and a slider 42. The slide rail 41 is vertically fixed to one side of the oil outlet pipe 2, and the slider 42 is slidably connected in the slide rail 41. A connecting hole 421 is provided on the slider 42. One end of the oil supply pipe 5 is connected to the slider 42, and the other end is connected to the engine. The slider 42 can slide to the end of the connecting pipe 31, thereby connecting the oil supply pipe 5 to the connecting pipe 31 through the connecting hole 421. When the slider 42 moves and connects with the connecting pipe 31, the solenoid valve 32 is energized, allowing fuel to flow out of the fuel tank 1, thus enabling the engine to draw fuel through the fuel supply pipe 5.
[0037] Reference Figure 3 Contact switches 43 are installed at both ends of the slide rail 41. The sliding of the slider 42 triggers the contact switches 43. When the slider 42 slides to the position connecting to the connecting pipe 31, it triggers one of the contact switches 43, causing the solenoid valve 32 to actuate via the contact switch 43, thus opening the connecting pipe 31. When the slider 42 slides to the middle of the oil outlet pipe 2, it disengages from both contact switches 43. At this time, both solenoid valves 32 remain closed, thereby reducing the probability of fuel leakage from the fuel tank 1.
[0038] Reference Figure 3 An electromagnet is installed at the end of the slide rail 41, and the electromagnet is magnetically connected to the slider 42. When the slider 42 slides and approaches the electromagnet, the electromagnet applies a magnetic force to the slider 42, thereby enabling the slider 42 to move quickly to the end of the oil outlet pipe 2 and connect with the corresponding connecting mechanism 3. When the slider 42 is connected to the connecting pipe 31, the electromagnet is magnetically connected to the slider 42, thereby reducing the probability of the slider 42 vibrating and disengaging from the connecting pipe 31. A controller is connected to the electromagnet, and a gravity sensor is connected to the controller. The gravity sensor is used to detect the acceleration direction of the target drone. When the target drone is flying upright, the gravity sensor detects that the overall acceleration direction of the target drone is downward. The gravity sensor transmits the signal to the controller, which controls the electromagnet below the slide rail 41 to work, so that the electromagnet below the slide rail 41 is magnetically connected to the slider 42, thereby enabling the slider 42 to slide quickly to the bottom of the slide rail 41 and connect with the connecting mechanism 3 below the fuel tank 1. When the target drone is flying backward, the gravity sensor detects that the target drone is accelerating upward. At this time, the controller controls the electromagnet on the upper side of the slide rail 41 to be energized, thereby enabling the slider 42 to slide quickly on the slide rail 41 and connect with another connecting mechanism 3.
[0039] Reference Figure 4 In other embodiments, the connecting part 21 is configured as an inclined tube, and the connecting part 21 is set at an acute angle relative to the vertical part 22. When there is a small amount of leaked fuel in the oil outlet pipe 2, the fuel can accumulate at the connection between the connecting part 21 and the vertical part 22, thereby reducing the probability of fuel in the oil outlet pipe 2 flowing out of the connecting mechanism 3 and reducing the probability of fuel leakage in the target machine.
[0040] The implementation principle of this application embodiment is as follows: by setting an oil outlet pipe 2 outside the oil tank 1, and setting two connecting mechanisms 3 on the oil outlet pipe 2, the oil supply pipe 5 can be connected to the two connecting mechanisms 3 respectively through the sliding mechanism 4. When the target drone is flying forward and backward, the fuel in the oil tank 1 is located at the bottom and top respectively, and the engine can draw fuel from the bottom and top of the oil tank 1 respectively through the oil supply pipe 5, so as to stabilize the power of the target drone flight.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
