Anti-skid device for multi-rotor UAV landing on water

Abstract

The invention relates to an anti-skid device for multi-rotor UAV landing on water. The device includes: an anti-skid landing platform: installed on a ship on the surface of the water, and a plurality of holes with tapers on the top and bottom are densely arranged on it, for Insert and fix the UAV locator; UAV locator: there are multiple and installed at the bottom of the UAV landing bracket, and its shape, size, taper and hole match. Compared with the prior art, the present invention has the advantages of being suitable for landing on water, moving and swinging, smooth insertion, not easy to slide, and simple structure.

[0002] In the past ten years, UAV technology has developed rapidly, especially multi-rotor UAVs have been widely used in terrain mapping, disaster relief, battlefield reconnaissance, agricultural spraying, film and television aerial photography and consumer entertainment. The advantages of multi-rotor UAVs are low cost, no risk of casualties, diverse functions, and ease of use. It is especially suitable for use in scenes with strict cost restrictions or in dangerous scenes. The impact is not obvious when flying over land, because drones can land at any time to replenish energy, but when flying over water, it will cause big problems, and it needs to be used in conjunction with unmanned boats or manned ships with long endurance to obtain continuous energy supply

[0003] The prerequisite for multi-rotor drones to obtain continuous energy supply is to land on the platform and no longer slide. However, multi-rotor drones may be affected by multiple factors when they land on the platform on water. "Turn over", first of all, the multi-rotor UAV has a relatively large wind surface, and if the ambient wind is strong, it will make it slide. This causes the UAV to slide when it lands. Finally, the unmanned boat is affected by the wind, waves and currents on the water, and its position and attitude are constantly changing, which causes the UAV to slide when it lands, and finally makes the UAV unable to effectively supply energy.

[0004] The existing multi-rotor UAV landing technology can be roughly divided into two categories: one is to use an active mechanical structure to locate the UAV, and its disadvantage is that the mechanism is more complicated; the other is to use a passive structure to locate the UAV. Positioning varies in complexity. The common feature of these inventions is that they are proposed for fixed-point landing on the ground for multi-rotor UAVs, and cannot be applied to landing applications on water, moving or swinging
