Problems solved by technology

Due to the use requirements of the recovery site, the wide use of small UAVs is greatly limited, especially in the field of surveying and mapping aerial photography. After the task is completed in the surveyed area, it is necessary to ensure sufficient fuel or power to meet the needs of small UAVs to return to the landing site. This greatly affects the work efficiency of small drones
Moreover, the traditional UAV landing method has low positioning accuracy and low reliability.

Embodiment 1

[0029] Such as Figure 1-8 A UAV recovery and charging device based on an extended parallel mechanism is shown, and the schematic diagram of the UAV recovery and charging device mounted on an unmanned boat is shown in Fig. figure 1 As shown, among them, the structure of the UAV recovery charging device is as follows figure 2 As shown, it includes a lifting mechanism 1, an extending parallel mechanism 2 and a UAV landing mechanism 3 arranged in sequence from bottom to top.

[0030] The lifting mechanism 1 lifts the stretching parallel mechanism 2 and the UAV landing mechanism 3. When not in use, the lifting mechanism 1 lowers the device of the present invention to the lowest state, so that the device of the present invention can be placed inside the unmanned boat, effectively avoiding The depreciation and aging of the device of the present invention, when in use, the replica on the unmanned boat is opened, and the lifting mechanism 1 lifts the device of the present invention,...

Embodiment 2

[0045] A method of utilizing the unmanned aerial vehicle described in embodiment 1 to reclaim the charging device for work, comprising the following steps:

[0046] (1) When receiving the UAV landing signal, open the hull flap, start the hydraulic cylinder motor of the lifting mechanism 1, the lifting mechanism 1 rises with the movement of the piston rod of the hydraulic cylinder, and push the stretching parallel mechanism 2 to rise;

[0047] (2) Start the lifting motor 54 of the drone landing mechanism 3, and drive the charging tube 56 through the lifting screw 55 to move upward;

[0048] (3) The angle sensor installed on the extension parallel mechanism 2 detects the inclination angle of the top plate 22, and the angle sensor outputs the change of the inclination angle of the top plate 22 as a voltage signal change. A control instruction is issued to control the three linear driver modules 27 of the stretching parallel mechanism 2 to perform angle adjustment actions to adjus...

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and specifically relates to a reclaiming and charging device for unmanned aerial vehicles based on a stretching parallel mechanism, which includes a lifting mechanism, a stretching parallel mechanism and a drone landing mechanism arranged in sequence from bottom to top; the drone landing mechanism There is a charging positioning device on the top of the top, and a lifting charging device inside, and the lifting and grabbing devices are symmetrically arranged on both sides of the lifting and charging device, and an infrared beacon is arranged on the lifting and grabbing device; , a top plate is vertically arranged on the base plate, and three extension structures are arranged between the base plate and the top plate, and the three extension structures are distributed in an equilateral triangle on the base plate, and the bottom and top ends of the extension structures are respectively fixedly connected to the base plate and the top plate; the present invention Utilizing the leveling characteristics of the stretching parallel mechanism, the top plate of the stretching parallel mechanism is always in a horizontal state, which is conducive to the precise recovery and charging of the drone by the drone landing mechanism.

Description

technical field [0001] The invention belongs to the technical field of drones, and in particular relates to a recovery and charging device for drones based on an extension parallel mechanism. Background technique [0002] In recent years, drone technology has developed very rapidly. UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. Compared with manned aircraft, unmanned aerial vehicles have the advantages of small size, low cost, convenient use, low requirements on the combat environment, and strong battlefield survivability. They have been widely used in military and civilian fields. [0003] Since there is no human control in the drone, the recovery technology of the drone is particularly important. Due to the use requirements of the recovery site, the wide use of small UAVs is greatly limited, especially in the field of surveying and mapping aerial photography. After the task is completed in the surveyed a...
