[0001] The utility model relates to the field of unmanned aerial vehicle radar installation structures, in particular to a microwave rain radar installation mechanism for an unmanned aerial vehicle. Background Art

[0002] In actual use, airborne microwave rain radar uses the microwave signal attenuation during the propagation of microwaves in rainy areas, which is referred to as microwave rain attenuation. By collecting the transmission power and received signal strength at the transmitting and receiving ends of the microwave link, the total attenuation of microwave propagation is calculated by differential calculation, and the microwave rain attenuation can be obtained by adopting a specific rain attenuation extraction algorithm. Then, the relationship between microwave rain attenuation and rain intensity is used to invert the path rain intensity.

[0028] 1. The utility model provides a sealing block, a card slot, a through hole, and a protective mechanism, wherein the sealing block with a circular structure can better cooperate with the card slot, provide a larger contact area, and thus enhance the sealing effect. Moreover, the card connection design makes the installation process simpler and faster, while ensuring the accuracy and stability of the installation position. At the same time, the engineering plastic material is light and low in cost, suitable for non-load-bearing or secondary structural components, which helps to reduce the weight of the entire installation mechanism. In addition, the protective shell and the inner bin in the protective mechanism are designed to cover and protect the key connection point between the bolt head and the external nut. This protection can prevent the connection point from being affected by bad weather, dust, dirt or other external factors, thereby ensuring the stability and safety of the connection. Through the meshing design of the threaded ring and the threaded groove, the protective shell can be easily installed and disassembled, which is very beneficial for daily maintenance and overhaul. Maintenance personnel can easily access the bolt head and nut for inspection, tightening or replacement. In addition, by reducing the exposure and corrosion of key components such as the bolt head and nut, the protective mechanism helps to extend the service life of these components.

[0029] 2. The utility model provides an umbrella-shaped block, and such a structure can better fit the main frame and fill any tiny gaps that may exist, thereby preventing moisture, dust or other contaminants from penetrating into the installation mechanism through these gaps. This is particularly important when the UAV performs tasks in harsh environments, and can ensure that the radar mechanism and other components of the UAV are protected from damage by the external environment. Moreover, the close fit between the umbrella-shaped block and the main frame can also help reduce noise and mechanical wear caused by vibration during flight. This design can reduce the dynamic stress at the installation interface, thereby improving the reliability and durability of the entire installation mechanism. In addition, the umbrella-shaped block may have a certain degree of elasticity, which helps to provide additional pre-tightening force during the installation process, so that the radar mechanism can be more firmly installed on the main frame.
