Title:
UNMANNED-AERIAL-VEHICLE-BASED MOVABLE CRUISE ILLUMINATION DEVICE FOR OCEAN PORT
Document Type and Number:
WIPO Patent Application WO/2022/036561
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of cruise illumination devices, and particularly relates to an unmanned-aerial-vehicle-based movable cruise illumination device for an ocean port. As for the problems that an existing cruise illumination device for an ocean port needs to be artificially driven to perform navigation illumination on ships such as passing warships, and that a searchlight can only expand a searchlight range by means of rotation, and has limited practicability, the solution of the present invention is provided. The movable cruise illumination device of the present invention comprises a lifting platform, wherein an annular groove is provided in the top of the lifting platform; a movable illumination apparatus is arranged in the annular groove in a sliding manner; the bottom of the movable illumination apparatus is provided with two first clamping grooves, in which the same first rotating shaft is rotatably connected; and two ends of the first rotating shaft are fixedly sleeved with rollers. When a first rolling shaft rotates, a first bevel gear and the first rotating shaft can be rotated by means of a second bevel gear, such that rolling shafts can roll on annular sliding rails, and therefore, the movable illumination apparatus can be pushed to move cyclically, thereby increasing an illumination coverage area.
