Description

Technology Field

[0001] The present invention relates to a battery charging device for a drone, and more specifically, to a battery charging device for a drone that enables the charging device for charging a pest control drone to be stably fixed to a vehicle, thereby facilitating the charging of the battery of the pest control drone. Background Technology

[0003] Generally, when the area to be sprayed with pesticides is small to protect crops from various pests and diseases, the worker carries the sprayer on their back and performs the pesticide spraying work manually. However, when spraying pesticides over a relatively large area such as a paddy field or a dry field, a cargo box equipped with a pesticide spraying device and a hose winding device is attached to a tractor, and the pesticide spraying device and hose winding device are driven by hydraulic pressure generated while driving the tractor to spray pesticides over a large area of ​​farmland in a short period of time.

[0005] However, the method of spraying pesticides by carrying a sprayer on the shoulder or spraying using a pesticide spraying device involves the inconvenience of having to move while spraying pesticides, and requires a significant amount of labor and time.

[0007] To address these issues, a flight spraying method capable of spraying pesticides using an unmanned drone has recently been disclosed in Korean Registered Utility Model No. 20-0479365.

[0009] Pesticide spraying drones using such flight spraying types consume a large amount of battery power to operate the internal control unit during long flights. Therefore, after completing a certain amount of flight time, the drone is guided to a station to recharge the battery via wireless charging methods.

[0011] However, the aforementioned pesticide spraying drone had a problem of reduced operational efficiency because it could not perform work while the battery was charging.

[0013] Meanwhile, in order to maintain the continuity of operations, a separate battery charging device is often carried in the vehicle. However, when loading the charging device into the vehicle's cargo compartment, there was an inconvenience in that it required a lot of effort to lift it from the ground into the vehicle's cargo compartment after separating the battery from the drone.

[0015] In addition, as the agricultural population ages, the age of drone users is also increasing, and recently, drones are trending toward larger sizes, with the battery alone required for operation weighing more than 12 kg. As a result, the inventor has developed a drone battery charging device that can assist users with insufficient muscle strength and help prevent musculoskeletal disorders. Prior art literature
