Problems solved by technology

[0003] In order to overcome the deficiencies in existing high-power laser applications and UAV load capacity, the present invention proposes a UAV laser relay redirection energy transmission device with simple structure, cost saving and wide application range. The UAV platform realizes the energy transmission and redirection functions of broken lines and complex optical paths, which solves the problem of straight-line propagation and continuous divergence of laser light during long-distance transmission and the problem that the load of the UAV platform cannot meet the weight of high-power lasers

Embodiment 1

[0033] as attached figure 1As shown, a UAV laser relay redirection energy transmission device, the UAV 1 flies to the vicinity of the action target and hovers, the UAV 1 provides a platform close to the action target, and the redirector 2 is installed on the unmanned In the lower part of the machine 1, the redirector 2 transmits the light that was originally transmitted in a straight line along a specific broken line optical path, and establishes the system observation optical path of the target-redirector 2-transmitter 3, and the redirector 2 will act on the image of the target The information is transmitted to the emitter 3 along the optical path of the system observation. According to the reversible principle of the optical path, the emitter 3 emits laser light to form the laser emission path of the emitter 3—the redirector 2—the target. The laser emitted by the emitter 3 is emitted along the laser The optical path is transmitted to the target. In the case of pre-adjusting ...

Embodiment 2

[0059] as attached Image 6 As shown, a UAV laser relay redirection energy transmission device differs from Embodiment 1 in that the redirector 2 adopts a concave full-reflection mirror, which is used to reflect the optical path and focus the laser, and pass through the concave surface The attitude adjustment of the total reflection mirror makes the system observation optical path and the laser emission optical path coaxial, and the transmitter 3 transmits the received laser light emitted by the laser 5 to the concave total reflection mirror, and reflects the laser light to the target through the concave surface total reflection mirror , so that the laser bypasses obstacles to process the target.

Embodiment 3

[0061] as attached Figure 7 As shown, an unmanned aerial vehicle laser relay redirection energy transmission device differs from Embodiment 1-2 in that: the unmanned aerial vehicle 1 is provided with multiple planes, and the redirector 2 of each unmanned aerial vehicle 1 is aligned Different targets or different angles of the same target, when it is necessary to process different targets, it may take time to temporarily adjust the angle of the redirector 2, and switch directly through the attitude of the launcher 3. The redirection has been adjusted The UAV 1 with the angle of the device 2 can more efficiently process different action targets or different angles of the same action target.

Abstract

The invention provides an unmanned aerial vehicle laser relay redirection energy transmission device, and belongs to the technical field of laser assisted machining. The unmanned aerial vehicle laserrelay redirection energy transmission device comprises an unmanned aerial vehicle provided with a redirector and a laser device provided with a master control system and an emitter. Communication signals are established between the unmanned aerial vehicle and the master control system. The master control system is used for controlling the laser device to generate lasers with different power. The laser device is connected with the emitter capable of steering by optical fibers. The emitter is used for tracking and aiming the redirector capable of steering. The redirector is used for reflecting and focusing the laser onto a target. Through adjusting the steering of the emitter and the redirector, a systematic observation optical path being coaxial with a laser emission path is achieved. The unmanned aerial vehicle is not necessarily provided with the heavy laser device, through adjusting the redirector to aim at the target and adjusting the emitter to track and aim the redirector, bypassing an obstacle can be effectively achieved through reflection, and the laser can be transmitted and focused onto the target.

Description

technical field [0001] The invention belongs to the technical field of laser-assisted processing, and in particular relates to an unmanned aerial vehicle laser relay redirection energy transmission device. Background technique [0002] High-power lasers can be widely used in industrial processing, national defense, scientific research and other fields. Especially in the industrial field, mature laser cutting, laser coating, laser welding and other devices have appeared, which have played an important role in promoting the development of my country's industry. In the process of long-distance transmission, high-power lasers propagate along a straight line and diverge continuously during the propagation process. Therefore, most of the current high-power laser processing equipment is used in the indoor environment of the factory building, and the robotic arm is close to the target for construction. However, in the wild, forest land In complex terrain operation requirements or ov...
