Non-time-limit ground power and pesticide supply plant protection unmanned aerial vehicle

Abstract

The invention relates to a non-time-limit ground power and pesticide supply plant protection unmanned aerial vehicle. The non-time-limit ground power and pesticide supply plant protection unmanned aerial vehicle comprises a power supply module, a pesticide supply module, a power transmission and pesticide conveying cable, a movable lifting platform, a tension induction line reeling and unreeling device and a plant protection unmanned aerial vehicle body. The power supply module converts the alternating current of an electric generator into the high-voltage direct current through an alternating and direct current electric transducer and transmits the high-voltage direct current to a high-voltage direct current line. The pesticide supply module uses an anti-corrosive high-pressure pump for pumping pesticide in a pesticide matching barrel into a pesticide conveying pipe. The power transmission and pesticide conveying cable is composed of the high-voltage direct current line and the pesticide conveying pipe and connected with the plant protection unmanned aerial vehicle body through the tension induction line reeling and unreeling device. The non-time-limit ground power and pesticide supply plant protection unmanned aerial vehicle is flexible in control and convenient to operate, and the working time is not limited.

Description

Technical field [0001] The invention relates to the technical application field of a plant protection drone, in particular to a plant protection drone with no time limit for ground power supply and medicine. Background technique [0002] At present, there have been ground-powered drones, some directly use low-voltage DC power generation, some use AC to convert to low-voltage DC, and some use high-voltage AC power supply. However, the excessive diameter of the transmission cable increases the weight of the cable. , The transmission distance is too small and other issues. Plant protection UAV is a new product of modern agriculture and forestry technology and equipment development. It is an unmanned aircraft specially used for agriculture, forestry and plant protection operations. Compared with the original plant protection technology, UAV plant protection has the advantages of high efficiency, flexibility, environmental protection and safety. In recent years, the agricultural plan...

AI Technical Summary

Problems solved by technology

Frequent battery replacement greatly affects work efficiency and increases workload

And the replaced battery generally needs to be charged quickly to ensure the operation of the drone. Every fast charge will basically cause damage to the lithium battery.

result in an indirect increase in operating costs

[0004] 2. The drug load is too small: the current plant protection drones generally have a full load of about 5 kg to 15 kg

Every time after spraying the medicine, the drone must return to refill the medicine, which wastes battery power and operation time, seriously affecting the work efficiency

[0005] 3. The nozzle is easy to block: due to the restriction of the battery power supply, the pressure of the spraying hydraulic pump is limited. When spraying powder and liquid mixed pesticides, the nozzle and nozzle are easily blocked, which seriously affects the normal operation.

[0006] 4. Frequent dosing of drones increases the risk of human injury, and is time-consuming and labor-intensive, increasing labor costs
