Autonomous flight pesticide spraying unmanned aerial vehicle controlled precisely

The invention provides an autonomous flight pesticide spraying unmanned aerial vehicle controlled precisely and a plant protection method using the autonomous flight pesticide spraying unmanned aerialvehicle controlled precisely. The autonomous flight pesticide spraying unmanned aerial vehicle comprises a fuselage, four or more rotor wings, an undercarriage, a mounting plate, an externally-hung pesticide box, a control device and a power source. The control device of the unmanned aerial vehicle collects environment data in real time, and comprehensive dynamic adjustment is conducted accordingto the environment data, specifically, the expansion amount of expansion joints is adjusted according to the deviation angle, a wind speed empirical value is added on the basis of the expansion amount, and thus spraying precision is improved; and PWM is adjusted according to the wind speed, the spraying amount is increased, and the unmanned aerial vehicle plans a path automatically and makes a return flight automatically under the situation that the wind speed is too large. According to the autonomous flight pesticide spraying unmanned aerial vehicle controlled precisely, the spraying precision can be effectively improved, and the using safety of the unmanned aerial vehicle is improved.

Dust removal system and dust removal method of air-conditioner outdoor unit

The invention relates to air-conditioners in the field of household appliances, and discloses a dust removal system of an air-conditioner outdoor unit. The dust removal system of the air-conditioner outdoor unit resolves the problems that a manual dust removal method in the traditional technology wastes labor power and is dangerous, and due to the fact a reverse rotation mode of an outdoor motor is adopted for dust removal, the service life of a fan is shortened, and the dust removal effect is poor. The dust removal system of the air-conditioner outdoor unit comprises a water discharge pipe and an externally connected pipe, wherein the water discharge pipe is connected with a water outlet of an indoor unit through a water inlet end and is used for discharging condensate water produced by heat exchange of the indoor unit, a water discharge structure is arranged at a water outlet end of the externally connected pipe, and the water discharge structure is located in a space between a top cover of the outdoor unit and the upper surface of a heat exchanger, is provided with water outlet holes, and is used for discharging water to the heat exchanger of the outdoor unit for dust removal. Besides, the invention further discloses a corresponding dust removal method which is suitable for dust removal of household air-conditioner outdoor units.
