Multi-rotor hybrid power plant protection unmanned aerial vehicle

Abstract

The invention provides a multi-rotor hybrid power plant protection unmanned aerial vehicle, which comprises a gasoline engine rotor, an engine, a battery, aircraft frames, a foot support frame, a pesticide box, a spray rod, a spray head and a remote controller, wherein the gasoline engine rotor is a single wing; the number of the aircraft frames is an even number, and the aircraft frames are uniformly and horizontally arranged on the periphery of a fixing plate arranged in the middle of the aircraft frames; the end part of each aircraft frame is provided with a small rotor, and each small rotor is driven by a small motor; two spoilers are arranged on the aircraft frame arranged under the single gasoline engine rotor. The multi-rotor hybrid power plant protection unmanned aerial vehicle has the advantages that the structure is simple, the self weight is light, the manufacturing cost is low, the load capacity is great, the duration time is long, the flight is stable, no pollution is caused, the repair is simple, and the like. The repair and the flight training are very simple, the long-time maintenance-free effect can be realized, and the after-sales service intensity is greatly reduced; the operation and control simplicity and stability of the unmanned aerial vehicle are greatly improved; the maintenance simplicity is realized; the time cost is reduced; the use efficiency of a battery is greatly improved.

Description

technical field [0001] The invention relates to a multi-rotor unmanned aircraft used for agricultural and forestry plant protection operations, in particular to an oil-electric hybrid multi-rotor aircraft. Background technique [0002] At present, the domestic industry-leading UAV manufacturers such as Zhuhai Yuren, Zhuhai Yintong, Anyang Quanfeng, Xi'an Wade, Shenyang Jinfengchun, Wuxi Hanhe, and North Tiantu are mainly divided into two types of plant protection drones. Animal and plant protection drones and electric plant protection drones, the comparison between the two is as follows: [0003] Oil plant protection UAV: [0004] Its advantages are: 1. Large load, 10-30L is more common; 2. Long battery life, 30-120 minutes, and a wide range of operations per unit price; 3. Gasoline and engine oil are used as fuel, and the fuel is easy to obtain. [0005] The disadvantages are: 1. Since the fuel is mixed with gasoline and engine oil, the incompletely burned waste oil will...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages are: 1. Since the fuel is mixed with gasoline and engine oil, the incompletely burned waste oil will be sprayed on the crops, causing crop pollution; 2. The price is high. The general price of high-power plant protection drones is 15-200 3. The overall maintenance is relatively difficult, because gasoline is used as power, and its failure rate is higher than that of the motor; 4. The engine wears a lot, and the life span is 300-500 hours

Since the part of the gasoline engine that provides the main lift is a dual-rotor structure, the biggest problem is that the structure is complex and heavy, which occupies the most precious weight and space resources of the UAV.
