Description

Technical Field

[0001] The utility model belongs to the technical field of power supply for unmanned aerial vehicles, and in particular relates to a power pod for unmanned aerial vehicles with an auxiliary fuel tank. Background Art

[0002] UAV technology is increasingly used in modern military and civilian fields, and its power system is one of the key factors to ensure that UAVs can perform tasks for a long time and with high efficiency. For UAVs that require long flight time, traditional fuel engines have the disadvantages of low energy efficiency and limited flight time. Therefore, people have begun to explore the use of auxiliary power pods combined with micro-generators to charge UAV batteries, thereby improving their flight time.

[0003] A feasible solution to improve the endurance of drones is to mount an auxiliary power pod with a micro-power generation function on the bottom of the drone to charge the battery. This solution requires the pod design to have the characteristics of efficient energy conversion, stable attitude control, modularity and environmental adaptability. At the same time, the weight, size and imaging navigation capabilities of the pod also need to be considered to ensure that it will not affect the flight performance and mission execution of the drone. When implementing it, factors such as the drone's load capacity, flight dynamics characteristics and maintenance reliability need to be comprehensively considered to achieve the best results.

[0004] The micro generator is set in the power pod, and the power pod is also equipped with a fuel tank, which supplies fuel to the micro generator to power the drone. Since the volume of the fuel tank in the power pod is fixed, if the drone's endurance needs to be further increased, the fuel tank needs to be enlarged. However, the internal space of the power pod is limited, which affects the size design of the fuel tank. If the overall size and structure of the power pod are redesigned, the design and production costs will increase significantly. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to provide a UAV power pod with an auxiliary fuel tank, aiming to solve the above technical problems.

[0006] The utility model adopts the following technical solutions:

[0007] The UAV power pod with auxiliary fuel tanks includes a cabin body, in which a main fuel tank and a micro-generator are arranged, and a plurality of auxiliary fuel tanks are installed on the outside of the cabin body through a connecting component, the lowest position of the auxiliary fuel tank is connected to the main fuel tank through an oil supply branch pipe, and the main fuel tank is connected to the micro-generator through an oil supply main pipe.

[0008] Furthermore, there is a pair of auxiliary fuel tanks, which are symmetrically installed on both sides of the cabin top, and the cross-section of the auxiliary fuel tanks is triangular.

[0009] Furthermore, the connecting assembly includes a mounting seat, the bottom surface of the mounting seat is an arc that matches the surface of the cabin, and the top surface is a groove that matches the auxiliary fuel tank. The mounting seat fixes the auxiliary fuel tank through a steel belt.

[0010] Furthermore, both ends of the mounting seat are weight-reducing holes.

[0011] Furthermore, a support frame is arranged in the cabin along the length direction, and the main oil tank is arranged in the middle of the support frame.

[0012] Furthermore, the support frame includes a plurality of support rings, and reinforcing plates are connected between adjacent support rings, and the main oil tank is installed on the middle support ring.

[0013] The beneficial effect of the utility model is that the power pod is provided with two auxiliary fuel tanks on the outside of the pod body, and the auxiliary fuel tanks are connected to the main fuel tank through oil delivery branch pipes. When the fuel in the main fuel tank is insufficient, the fuel in the auxiliary fuel tanks can be pumped into the main fuel tank, thereby realizing the expansion of the fuel tank volume in an external manner, without the need to redesign the power pod, with low modification cost and increased endurance of the UAV.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0020] like Figure 1-4As shown, the UAV power pod with auxiliary fuel tanks provided in this embodiment includes a cabin body 1, in which a main fuel tank 2 and a micro generator 3 are arranged, and a plurality of auxiliary fuel tanks 5 are installed on the outside of the cabin body 1 through a connecting component 4, and the lowest position of the auxiliary fuel tank 5 is connected to the main fuel tank 2 through an oil supply branch pipe 51, and the main fuel tank 2 is connected to the micro generator 3 through an oil supply main pipe 21.

[0021] The power pod is cylindrical as a whole, with a flat top surface. A hanging plate 7 is generally provided, and the power pod is installed at the bottom of the UAV through the hanging plate. There is a pair of auxiliary fuel tanks, which are symmetrically installed on both sides of the top of the cabin body. The cross-section of the auxiliary fuel tank is triangular. In the figure, since the two sides of the top of the cabin body are arc-shaped, space can be formed to install the auxiliary fuel tank. The auxiliary fuel tank is also close to the bottom of the UAV, which is also convenient for the oil in the auxiliary fuel tank to be pumped into the main fuel tank. In specific implementation, a micro oil pump is installed on the pipeline of the oil delivery branch pipe of the auxiliary fuel tank. This embodiment does not limit the specific installation position. For example, it is set at the oil outlet of the auxiliary fuel tank, or at the inlet position of the main fuel tank.

[0022] The auxiliary fuel tank is a triangular prism with three curved sides. Its bottom side is at the lowest position, which is conducive to oil discharge. The top of the auxiliary fuel tank is flat and does not interfere with the bottom of the drone. Therefore, this structural design makes full use of the appearance characteristics of the existing power pod, reasonably designs the structure of the auxiliary fuel tank, ensures compact installation, does not affect other components, and is convenient for oil discharge.

[0023] The auxiliary fuel tank is installed on the cabin through the connecting assembly 4, combined with Figure 3 , 4 As shown, the connection assembly 4 includes a mounting seat 41, the bottom surface of the mounting seat 41 is an arc that matches the surface of the cabin 1, and the top surface is a groove that matches the auxiliary fuel tank 5. The mounting seat 41 fixes the auxiliary fuel tank 5 through a steel belt 42. After fixation, the groove of the mounting seat matches the auxiliary fuel tank, and the bottom of the mounting seat matches the shape of the cabin surface, ensuring the firmness of the installation and preventing shaking. In addition, the two ends of the mounting seat 41 are weight-reducing holes 43, which reduce the weight while ensuring strength.

[0024] The main oil tank 2 is installed inside the cabin 1. A support frame 6 is arranged in the cabin 1 along the length direction. The main oil tank is arranged in the middle of the support frame 6. The support frame 6 includes a plurality of support rings 61. Reinforcement plates 62 are connected between adjacent support rings 61 to ensure the mechanical strength of the cabin. The main oil tank 2 is installed on the middle support ring 61. In the figure, the top of the cabin is a hanging plate 7, which is installed between two reinforcement plates 62 located at the top.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
