Description

Technical Field

[0001] The utility model belongs to the field of auxiliary power pods, and particularly relates to a fuel tank installation module for a power pod. Background Art

[0002] With the rapid development of unmanned aerial vehicle (UAV) technology, UAVs need to carry more power-consuming devices, resulting in a significant increase in the power supply demand of UAVs.

[0003] There are various types of UAV power. For long-endurance UAVs, a fuel engine is generally used to provide flight power, and a small battery is carried on the UAV, but its power supply is limited. Although the fuel engine can also charge the battery, the conversion efficiency is low, which will also affect the endurance of the UAV. In order to provide sufficient power to the UAV without significantly affecting its endurance, an aviation auxiliary power pod can be mounted at the bottom of the UAV, and the pod uses a micro-generator to generate electricity to charge the battery.

[0004] The micro-generator in the pod uses fuel as an energy source and can be directly connected to the fuel tank of the UAV through a conduit to provide energy for the micro-generator through the fuel of the UAV. However, the endurance of the UAV is determined by the amount of fuel in the fuel tank, and this method will significantly reduce the endurance of the UAV. Therefore, in order to minimize the impact of mounting the aviation auxiliary power pod on the UAV's endurance, it can be considered to set a fuel tank in the pod. However, issues such as the size setting of the fuel tank, lightweight design, and installation firmness design need to be considered. Content of the Utility Model

[0005] In view of the above problems, the purpose of the utility model is to provide a fuel tank installation module for a power pod, aiming to solve the above technical problems.

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

[0007] The fuel tank installation module for a power pod includes a housing. There is a suspension member at the top of the housing. The housing includes front and rear square frames, and a chassis with a frame structure is fixed between the bottoms of the front and rear square frames. Multiple fixing rods are connected between the tops of the front and rear square frames. A fuel tank is placed on the chassis. There are ear blocks at the four corners of the bottom of the fuel tank. 7-shaped seats are fixed on the left and right sides of the bottoms of the front and rear square frames. The 7-shaped seats press the ear blocks on the same side and are locked to the chassis through bolts, and the ear blocks are locked to the chassis through screws.

[0008] Further, the suspension member includes a top cover that is clamped between the middle two fixing rods. The two sides of the top cover are L-shaped plates, and the middle is a circular ring opening. A fixing block is detachably installed in the circular ring opening, and there is a lifting lug at the top of the fixing block.

[0009] Further, triangular plates are fixed between the fixing rods on the left and right sides and the front and rear square frames.

[0011] Further, a liquid level gauge and a breather valve are also provided on the fuel tank, and a reinforcing rod is provided around the outer periphery of the fuel tank.

[0012] The beneficial effects of the present utility model are as follows: In this structure, the fuel tank installation module as a whole is a frame structure with a relatively light weight. The chassis for carrying the fuel tank also adopts a frame structure. The chassis not only serves as a carrier for the fuel tank, but also as a part of the casing to connect the bottoms of the front and rear square frames, minimizing the structure to reduce the weight. Moreover, the fuel tank is fixedly installed with the chassis and the front and rear square frames as a whole, with high installation firmness and being convenient for disassembly, installation and maintenance.

[0017] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.

[0019] As Figures 1-3As shown in the figure, the fuel tank installation module for a power pod provided in this embodiment includes a housing 1. There is a suspension member 2 at the top of the housing 1. The housing 1 includes front and rear square frames 3, and a chassis 4 with a frame structure is fixed between the bottoms of the front and rear square frames 3. A plurality of fixing rods 31 are connected between the tops of the front and rear square frames 3. A fuel tank 5 is placed on the chassis 4. There are ear blocks 61 at the four corners of the bottom of the fuel tank 5. At the left and right sides of the bottom of the front and rear square frames 3, 7-shaped seats 62 are fixed. The 7-shaped seats 62 press the ear blocks 61 on the same side and are locked to the chassis 4 through bolts, and the ear blocks 61 are locked to the chassis 4 through screws.

[0020] The installation method of the fuel tank in this structure is simple and firm. The ear blocks of the fuel tank are installed and fixed integrally with the chassis and the front and rear square frames, with high installation firmness and being convenient for disassembly, assembly and maintenance. In addition, since the ear blocks have a certain thickness, multiple convex plates can be formed at different positions on the chassis to support the bottom of the fuel tank, ensuring the bearing stability.

[0021] In addition, the housing includes front and rear square frames. The outside of the housing is a cover plate. The overall fuel tank installation module is a frame structure with a relatively light weight. The chassis for carrying the fuel tank also adopts a frame structure, which not only serves as a carrier for the fuel tank, but also as a part of the housing to connect the bottoms of the front and rear square frames, minimizing the structure and reducing the weight, with a lightweight structural design. In addition, triangular plates 32 are fixed between the fixing rods on the left and right sides and the front and rear square frames to improve the firmness.

[0022] There is also a suspension member 2 at the top of this fuel tank installation module for hanging to the bottom of the unmanned aerial vehicle. As Figure 4 shown, the suspension member 2 includes a top cover 21 that is clamped between the middle two fixing rods. The two sides of the top cover 21 are L-shaped plates 22, and the middle is a circular ring opening 23. A fixing block 24 is detachably installed in the circular ring opening 23, and there is a lifting lug 25 at the top of the fixing block 24. In this structure, the top cover is limited between the middle two fixing rods and the front and rear square frames and cannot move up and down. Welding is not required, and the structure installation is simple.

[0023] In the figure, there is also a liquid level gauge 51 and a breather valve 52 on the fuel tank 5, and there is a circle of reinforcing bars 53 around the fuel tank. The reinforcing bars can increase the firmness of the fuel tank. The liquid level gauge can indicate the fuel level, and the breather valve allows one-way intake of air without affecting the fuel output.

[0024] Furthermore, ventilation meshes 11 are provided on both sides of the suspension member at the top of the housing 1. The ventilation meshes 11 are to prevent accidental gas overflow from the fuel tank, which may cause the cabin to be filled with fuel gas and pose a safety hazard. The ventilation meshes are designed at the top. When the pod is installed, the ventilation meshes are exactly below the unmanned aerial vehicle, playing a shielding role.

[0025] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
