Description

Active closed pulley for hanging power transmission overhead line through unmanned aerial vehicle Technical Field The utility model relates to the technical field of unmanned aerial vehicles, in particular to an active closed pulley for hanging a transmission overhead line through an unmanned aerial vehicle. Background At present, unmanned aerial vehicles are widely applied to various fields such as power inspection. The unmanned aerial vehicle has various types such as the flight control system is open, the flight control system is not open, there is hanging point and no hanging point. The control of unmanned aerial vehicle is realized through unmanned aerial vehicle's flight control system, and the unmanned aerial vehicle's flight control system is externally open, has set up corresponding interface on unmanned aerial vehicle's the flight control for connect the peripheral hardware, say throw and hang the device, can directly control unmanned aerial vehicle and throw and hang the device through unmanned aerial vehicle's remote controller, but just can't control through flight control system to unmanned aerial vehicle that flight control system is unopened and throw and hang the device, have received very big restriction to the application range of unmanned aerial vehicle that does not have the hanging point or flight control is unopened, and current throwing is hung the commonality of device too poor, can not adapt to the operation requirement of various types of unmanned aerial vehicle. During the operation of the transmission line, problems such as broken or loose strands of the lead and the ground wire, failure or missing of bolts and pins, deformation or damage of accessory facilities, displacement or abrasion of hardware fittings, loosening or disconnection of connecting points and the like often occur due to the influence of external environment. In order to ensure safe and stable operation and uninterrupted continuous power supply of the power transmission line, a live working mode is generally adopted to overhaul defects of the power transmission line. In order to change the heavy and high-strength working state of the power transmission line maintenance work, reduce the labor intensity and improve the maintenance efficiency, the live working is made to be an intelligent and portable age of tools. The unmanned aerial vehicle is fully utilized to combine the electric lifting device, and the energy efficiency of the electric lifting device is further improved. The method can avoid high-intensity operations such as rope climbing, climbing towers and the like of operators, reduce the labor intensity of the operators to the greatest extent, improve the overhaul efficiency, shorten the overhaul time, reduce the power failure time, improve the economic benefit of a power grid and realize the purposes of reducing the labor intensity and realizing the intellectualization and portability of tools. The disadvantage of the hanging point setting mechanism in the prior art is that the structure is complex, when the unmanned aerial vehicle hangs the unmanned aerial vehicle on a wire, the unmanned aerial vehicle can move relative to the wire under the action of the travelling pulley, and the mechanism is not applicable to the field where the fixed point is required to be set. Disclosure of utility model The utility model provides an active sealing pulley for hanging a power transmission overhead line through an unmanned aerial vehicle, which overcomes the defects in the prior art, adopts a pure mechanical structure, so that after the unmanned aerial vehicle is hung on the power transmission overhead line, the pulley can be actively sealed by loading a certain load, the uncertainty that other pulley structures form a sealing space by means of gravity is overcome, the unexpected falling of a lifting point mechanism from the power transmission overhead line is effectively avoided, and the safety of personnel is ensured. After the use is finished, the unmanned aerial vehicle lifting hook hangs the hoisting point mechanism through the unmanned aerial vehicle lifting ring structure, and the overturning piece is automatically opened under the action of the torsion spring, so that the power transmission overhead line is separated. No extra operation is needed in the process, and the reliability is high. In view of the above problems, the technical scheme provided by the utility model is as follows: The utility model provides a get transmission of electricity overhead line initiative closure coaster through unmanned aerial vehicle hanging, includes unmanned aerial vehicle rings, upset piece and rope hoisting point, the bottom rigid connection of unmanned aerial vehicle rings has frame construction, take shoulder hinge pin is installed to the one end of upset piece, the upset piece through take shoulder hinge pin with frame construction's bottom rotates to be connected, take shoulder hinge pin's both ends to overlap respec
