Embodiment 1

[0035] A self-stable multi-UAV landing device based on a parallel four-bar linkage mechanism for an unmanned boat platform, its structure is as follows Figure 1-Figure 9 As shown, including the unmanned boat 1, the unmanned boat 1 is provided with a six-degree-of-freedom parallel platform 2, and the six-degree-of-freedom parallel platform 2 is provided with a multi-layer rotating platform 5 matched with the six-degree-of-freedom parallel platform 2. Any platform on the rotating platform 5 is provided with a UAV fixing device 4, and the UAV fixing device 4 is provided with a UAV 3; the unmanned boat 1 is provided with a control system.

[0036]The six-degree-of-freedom parallel platform 2 includes a base 201, the base 201 is provided with a hydraulic cylinder 202, the hydraulic cylinder 202 is connected with an upper platform 204, and the upper platform 204 is provided with a level sensor; the hydraulic cylinder 202 is movably connected with the base 201 and the upper platform ...

Embodiment 2

[0041] A self-stable multi-unmanned aerial vehicle landing device based on a parallel four-bar linkage mechanism for an unmanned boat platform is different from Embodiment 1 in that: each claw platform 403 is provided with a claw.

[0042] When the unmanned aerial vehicle 3 needs to land, the rotating motor on the rotating shaft 506 drives the rotating shaft 506 to rotate, so that the fixed plate 505 of the unmanned aerial vehicle 3 that does not stay on the multi-layer rotating platform 5 is rotated, so that the vacant fixed plate 505 is in a multi-layer At the top of the rotating platform 5, at this time, the vacancy fixing plate 505 is in an unobstructed state, so as to avoid collisions when the UAV 3 lands. The UAV 3 recognizes the long-distance positioning mark on the carrying platform 401 on the vacancy fixing plate 505 through the onboard camera 301, and the UAV 3 calculates the relative position between itself and the carrying platform 401 on the unmanned boat 1, contin...

Abstract

The invention belongs to the technical field of unmanned aerial vehicle auxiliary equipment, and particularly discloses a self-stabilized multi-unmanned aerial vehicle landing device based on a parallel four-bar mechanism for an unmanned boat platform. The self-stabilized multi-unmanned aerial vehicle landing device comprises an unmanned boat, a six-degree-of-freedom parallel platform is arranged on the unmanned boat, a multi-layer rotating platform matched with the six-degree-of-freedom parallel platform is arranged on the six-degree-of-freedom parallel platform, unmanned aerial vehicle fixing devices are correspondingly arranged on any platform of the multi-layer rotating platform, and unmanned aerial vehicles are arranged on the unmanned aerial vehicle fixing devices. According to the self-stabilized multi-unmanned aerial vehicle landing device, through matching of the six-degree-of-freedom parallel platform and the multi-layer rotating platform on the unmanned boat, the multi-layer rotating platform can be ensured to be always in a horizontal state, a plurality of unmanned aerial vehicles can be stared and stopped, then the unmanned aerial vehicles and the unmanned aerial vehicle fixing devices are matched, the action of quickly and smoothly taking off and landing on of the unmanned aerial vehicles on the unmanned boat is achieved, and unmanned aerial vehicle landing gears on the unmanned aerial vehicles play a role of increasing of unmanned aerial vehicles fixing.

Description

technical field [0001] The invention belongs to the technical field of UAV auxiliary equipment, and in particular relates to a self-stable multi-UAV landing device based on a parallel four-bar linkage mechanism for an unmanned boat platform. Background technique [0002] With the rapid development of unmanned boat technology and UAV technology, they each play an important role in different fields, and they can all help us complete high-risk and high-intensity tasks to ensure the safety of human life to the greatest extent. . At present, a major research direction is to combine unmanned boat technology with UAV technology, which can greatly expand the functionality of the two. Exploration, while UAVs often have insufficient battery life. When the power of the UAV is low, it can fly back to the unmanned boat for charging, and multiple UAVs can perform tasks simultaneously or alternately. However, one of the difficulties in the cooperation of unmanned boats and drones is how ...
