Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) experimental equipment technology, and in particular to a UAV spraying experimental device. Background Technology

[0002] In recent years, drones have become an important part of the agricultural industry, which has developed rapidly. Rotary-wing drones are widely used in agricultural plant protection, and they have greatly improved agricultural production efficiency by accurately spraying pesticides and monitoring crop growth.

[0003] As drones are an emerging industry, there are many gaps in drone testing, especially for agricultural drones, where testing equipment is almost non-existent. Existing agricultural drones mainly consist of the drone itself, a pesticide tank, and a nozzle. The drone carries the pesticide tank, and the pesticide solution inside is sprayed downwards through the nozzle to spray crops. However, accurately detecting and judging the impact of different types of drone rotors on the spraying effect, as well as the impact of the drone's flight altitude, flight speed, ambient wind speed, and wind direction on the spraying effect, is a challenge for existing agricultural drones. Utility Model Content

[0004] In view of this, the present invention provides a drone spraying experimental device, the main purpose of which is to provide a drone spraying experimental device that can simulate and detect the spraying effect of drones.

[0005] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0006] This utility model embodiment provides a drone spraying experimental device, the device comprising:

[0007] A wind wall component, comprising a connecting frame and multiple single fan components, each single fan component being mounted on the connecting frame, each single fan component comprising a housing, a fan body, and a honeycomb rectifier, the fan body being disposed at one end of the housing, and the honeycomb rectifier being disposed at the other end of the housing;

[0008] The support component includes a support body, a cantilever component, and a motor. One end of the cantilever component is mounted on the upper part of the support body, and the other end is connected to the rotor blade of the UAV. The motor is mounted on the cantilever component and is used to drive the rotor blade to rotate. The wind wall component is disposed on the side of the support body.

[0009] Furthermore, the housing includes a first mounting section, a second mounting section, and a shrinking and pressurizing section. The two ends of the shrinking and pressurizing section are respectively connected to the first mounting section and the second mounting section. The fan body is disposed in the first mounting section, and the cellular rectifier is disposed in the second mounting section.

[0010] Furthermore, the shrinking and pressurizing section includes a first connecting housing, a second connecting housing, and an extension housing. The two ends of the first connecting housing are respectively connected to the first mounting section and the extension housing, and the two ends of the second connecting housing are respectively connected to the extension housing and the second mounting section.

[0011] Furthermore, the first connecting housing and the second connecting housing have a square cross-sectional shape at one end and a circular cross-sectional shape at the other end.

[0012] Furthermore, the cantilever component includes a first connecting rod and a second connecting rod. The first connecting rod is detachably connected to the bracket body, and the other end is detachably connected to the second connecting rod. The motor is mounted on the second connecting rod.

[0013] Furthermore, a nozzle is mounted on the lower part of the rotor blade.

The motor is mounted on the cantilever component to drive the rotor blades to rotate. The wind wall component is located on the side of the support body. Compared to existing technologies, conventional agricultural drones mainly include a drone body, a pesticide tank, and... The spray nozzle, carried by the drone itself, sprays the pesticide solution downwards onto crops. However, accurately detecting and judging the impact of different types of drone rotors on the spraying effect, as well as the influence of the drone's flight altitude, flight speed, ambient wind speed, and wind direction, is a challenge for existing agricultural drones.

Compared with existing technologies... Existing agricultural drones mainly consist of the drone body, a pesticide tank, and a nozzle. The drone body carries the pesticide tank, and the pesticide solution inside is sprayed downwards through the nozzle to spray crops. However, accurately detecting and judging the impact of different types of drone rotors on the spraying effect, as well as the impact of the drone's flight altitude, flight speed, ambient wind speed, and wind direction on the spraying effect, is a challenge for existing agricultural drones.
