Cable paying-off device and cable laying device of unmanned aerial vehicle

Abstract

The invention provides a cable paying-off device and a cable laying device of an unmanned aerial vehicle, belonging to the technical field of cable laying. The cable paying-off device comprises a mainframe, a cable winding reel and a driver, wherein the driver and the cable winding reel are connected with the main frame, and the driver is drivingly connected with the cable winding reel are connected with the main frame, and the driver is in transmission connection with the cable winding reel. The cable laying device of the unmanned aerial vehicle (UAV) comprises the UAV and the cable paying-off device, wherein the cable paying-off device is connected with the UAV. The invention provides the cable paying-off device and the cable laying device of the unmanned aerial vehicle, which can actively pay off the cable through the cable paying-off device provided with the driver and the cable winding reel, thereby reducing the pulling force of the cable and further guaranteeing the signal transmission performance of the optical fiber which can be damaged by an external force inside the cable.

Description

technical field [0001] The invention relates to the technical field of cable laying, in particular to a cable pay-off device and a cable laying device for an unmanned aerial vehicle. Background technique [0002] In recent years, the high-altitude laying technology of aerial cables and ADSS optical cables (non-metallic aerial optical cables) using drones has basically taken shape. One way is that before take-off, the construction personnel hang the lightweight and high-strength primary guide rope on the UAV, hang the primary guide rope on the guide wheel at the top of the tower through the UAV, and manipulate the UAV to fly to the UAV. For the guide wheel of the next tower pole, hang the primary guide rope on the guide wheel and throw it down, and then manually drag the primary guide rope to lay the secondary guide rope and cable connected to it between the two tower poles. Another way is to directly connect the UAV to the payoff, rely on gravity to passively pay off the ca...

[0003] However, when the above two methods use drones for construction, it is inevitable that there will be a certain pull on the cables, especially the way of combining drones with payoffs. During the laying process of drones, there will be If the cable is directly dragged, it is easy to cause the optical fiber inside the cable to be damaged by external force and affect its signal transmission performance
