Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of UAV power pods, and particularly relates to a UAV power pod provided with a wind guide cover. Background Technique
[0002] The application of UAV technology in modern military and civilian fields is becoming increasingly widespread, 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 endurance, traditional fuel engines have the disadvantages of low energy efficiency and limited endurance time. Therefore, people have begun to explore auxiliary power pods combined with micro generators to charge the batteries of UAVs, thereby improving their endurance.
[0003] To improve endurance, the fuel tank volume can be increased. In addition, it is also necessary to further improve the power generation efficiency of the micro generator. The micro generator uses fuel as fuel, and the fuel burns to generate electricity. In the current structure, an air inlet is opened at the side wall of the cabin body where the micro generator is located. The air inlet is generally a vertical strip-shaped opening, which is a passive air inlet. The turbine of the micro generator rotates to draw air into the internal part of the micro engine to burn with the atomized fuel. Since UAVs generally fly at high altitudes and the air is relatively thinner than that on the ground, the current air intake volume of the micro generator does not meet the requirements, resulting in incomplete fuel combustion and reduced oil-electricity conversion efficiency. Content of the Utility Model
[0004] In view of the above problems, the purpose of the utility model is to provide a UAV power pod provided with a wind guide cover, aiming to solve the above technical problems.
[0005] The utility model adopts the following technical scheme:
[0006] The UAV power pod provided with a wind guide cover includes a cabin body. A micro generator is arranged at the tail inside the cabin body. There is a circle of air inlets in the middle section of the micro generator. At least one air inlet hood protruding outward is arranged on the cabin body at the position of the micro generator. The front end of the air inlet hood is an air inlet. The air inlet of the micro generator is also connected with a wind guide cover, and the wind guide cover is communicated with the air inlet of the air inlet hood.
[0007] Further, the air inlet hood is a conical inclined plane.
[0008] Further, there are two air inlet hoods and wind guide covers, and they are arranged symmetrically left and right. The inner side of the tail of the wind guide cover is a semi-circular wind groove, and the bottom position between the two wind guide covers is an avoidance area.
[0009] Further, there are screw holes at the front edges of the two semi-circular wind grooves, and the rear edges are turned outwards and clamped into the hanging bracket of the micro generator.
[0010] The beneficial effects of the present utility model are as follows: For the drone power pod of the present utility model, the vertical strip-shaped air inlet on the side wall of the pod body is redesigned as an air inlet cover. The air inlet cover gradually tapers inward, and a wind guide cover is arranged at the air inlet position of the micro generator. The wind guide cover is communicated with the air inlet cover. This power pod has an active air intake structure. When the drone is flying, the air inlet cover at the bottom power pod faces the flying direction, and the air flow actively enters the micro generator through the air inlet cover and the wind guide cover to provide oxygen. Therefore, compared with the existing passive air intake method, the air intake volume can significantly improve the oxygen supply of the micro generator, ensure the fuel combustion efficiency, and reduce the energy consumption of the equipment.

[0017] In order to make the objectives, technical solutions, and advantages of the present utility model more clearly understood, the following further elaborates on the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely used to explain the present utility model and are not intended to limit the present utility model.
[0018] To illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.
[0019] As Figure 1-4 shown, the drone power pod with a wind guide cover provided in this embodiment includes a pod body 1. A micro generator 2 is arranged at the tail inside the pod body 1. There is a circle of air inlets 3 in the middle section of the micro generator 2. The pod body 1 is provided with at least one outwardly protruding air inlet cover 4 at the position of the micro generator. The front end of the air inlet cover 4 is the air inlet. The air inlet of the micro generator 2 is also connected with a wind guide cover 5, and the wind guide cover 5 is communicated with the air inlet of the air inlet cover 4.
[0020] In this structure, the air inlet of the air inlet hood is set forward, and the air inlet hood is arranged at the rear part of the cabin near the micro generator. In the figure, the air inlet hood is a conical inclined plane, that is, the air inlet hood gradually tapers inwards. A wind guide hood is also arranged in the cabin, and the wind guide hood is communicated with the air inlet hood. The tail of the wind guide hood is communicated with a circle of air inlets of the micro generator. The power nacelle is hoisted at the bottom of the UAV, and the installation direction is the same as the length direction of the UAV. When the UAV is flying, the air inlet hood of the bottom power nacelle faces the flying direction. Therefore, the air flow will actively enter the micro generator through the air inlet hood and the wind guide hood to provide oxygen. In the prior art, the air inlets on both sides of the cabin are generally vertical strip-shaped openings, and the air is pumped in by means of turbine air extraction. This method is an active air intake method. Therefore, in the present utility model, the vertical strip-shaped air inlets on the side wall of the cabin are designed and adjusted into air inlet hoods. Compared with the existing passive air intake method, the air intake volume of the power nacelle can significantly improve the oxygen supply of the micro generator, ensure the fuel combustion efficiency, and reduce the equipment energy consumption.
[0021] As a specific structure, in the figure, there are two air inlet hoods 4 and wind guide hoods 5, and they are arranged symmetrically left and right. The air inlet hoods are located on the left and right of the cabin and at the lower position. As Figure 4 shown, the inner side of the tail of the wind guide hood 5 is a semi-circular wind groove 50, and the two semi-circular wind grooves can be spliced into a complete annular air intake groove. Since the two wind guide hoods are independent, it is convenient for the installation between the wind guide hood and the micro generator. The position at the bottom between the two wind guide hoods is an avoidance area for accommodating the control components of the micro generator. Even if the wind guide hood is added, the overall volume of the power nacelle will not be increased.
[0022] Finally, in combination with Figure 5 、 6 shown, there are screw holes at the front edge 51 of the two semi-circular wind grooves 50, and the rear edge 52 is turned outwards and clamped into the hanger of the micro generator. As Figure 2 shown, the air inlet of the micro generator is a circle of brackets, and there is a circle of small flanges on the front side, and the rear side is a hanger for fixing the micro generator. The hanger includes a lower hoop 31 and an upper bracket 32, and there is a rubber pad 33 inside the lower hoop 31 and the upper bracket 32. When the wind guide hood is installed, the front edge 51 of its semi-circular wind groove can be locked to the small flange, and there is a turned-out edge around the rear edge 52, and the turned-out edge is clamped between the lower hoop 31 and the upper bracket 32 of the hanger, specifically inside the rubber pad 33, so that the installation and fixation of the wind guide hood can be well realized.
[0023] 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 replacements, and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
