AI Technical Summary

Technical Problem

Existing high-altitude cleaning drones rely on rotor tilt angle adjustments to counteract the recoil force of the jet water flow, resulting in shortened flight time and accelerated airframe fatigue. Traditional spring buffering has limited effectiveness and cannot effectively utilize external energy for buffering.

Method used

The system employs a spiral-patterned telescopic tube and a buffer cylinder system for multi-stage buffering, combined with a ground-based high-pressure water pump to provide kinetic energy. It utilizes Bernoulli's principle to achieve precise addition and fluid control of the cleaning fluid, and uses high-pressure water flow for active buffering to reduce the direct transmission of recoil force to the drone body.

Benefits of technology

It significantly extends the single-operation endurance of drones, reduces fatigue damage to the airframe structure, improves the operational stability and reliability of the cleaning system, and avoids the increased energy consumption and structural damage of traditional solutions.

Abstract

The invention relates to the technical field of unmanned aerial vehicles with special purposes, in particular to an autonomous cruise type intelligent high-altitude cleaning unmanned aerial vehicle device which comprises an unmanned aerial vehicle body and a temporary storage part arranged below the unmanned aerial vehicle body, a spraying assembly is arranged at the front end of the temporary storage part, and the bottom of the temporary storage part communicates with a water pump. A buffering assembly is further arranged at the front end of the temporary storage part, and the spraying assembly is connected with the temporary storage part through the buffering assembly. A multi-shaft adjusting part is arranged at the bottom of the unmanned aerial vehicle body, the temporary storage part is connected with the unmanned aerial vehicle body through the multi-shaft adjusting part, and a plurality of rotors are arranged on the unmanned aerial vehicle body; through the synergistic effect of primary buffering of the telescopic pipe and multi-stage buffering of the buffering cylinder system, a set of complete external energy buffering system is constructed, and reverse impact force generated when the spray gun works is effectively counteracted through kinetic energy provided by the ground high-pressure water pump; the limitation that a traditional high-altitude cleaning unmanned aerial vehicle depends on rotor wing adjustment or internal spring buffering is changed, and the cruising ability of the unmanned aerial vehicle is remarkably improved.
