The climbing device 10 of the present solution can use a dedicated micro-payoff drone for assisting in suspending the climbing belt 400 of the climbing device 10 onto a high-altitude power transmission line.
This unmanned aerial vehicle is accomplished by artifical handheld interface operation box. Firstly, a set of micro unmanned aerial vehicle suitable for flying across a power transmission line wire is built through research on technical requirements of a flight control system in the aspects of control precision and stability, load capacity, anti-interference capacity, endurance time, whole machine size, remote control distance and the like. Combine the visual technique of FPV, supplementary aerial position of unmanned aerial vehicle of observing, guarantee operation security. The pay-off device is arranged below the flight platform, the remote controller controls the PWM duty ratio of a steering engine channel of the receiver, the duty ratio is increased or reduced through adjustment, so that the steering engine is controlled to rotate, and the throwing function of the device is formed through mechanism design.
Miniature unwrapping wire unmanned aerial vehicle combines together by miniature unmanned aerial vehicle and pay-off. Can put in the back with insulating haulage rope through miniature unwrapping wire unmanned aerial vehicle and take on the target conductor to can let ground end personnel use this insulating haulage rope to pull the climbing area through 1 level line, realize climbing area and walk around from cable a top.
At this point, the placement of the climbing band 400 is achieved. The ends of the climbing band 400 hang freely. In order to prevent the cable from being damaged when the climbing belt 400 works, a wire hanging bracket 410 may be provided on the cable a.
At this time, both ends of the climbing belt 400 are wound into the belt drum 330 of the belt winding machine 300. Simultaneously, still be equipped with the gyroscope on climbing device 10's the base, still include automatic control system simultaneously, monitor behind the inclination of climbing device by the gyroscope and send data to microprocessor, then opening of microprocessor control each coiling machine's motor stops and speed to the realization is steadily climbed to the high-voltage line with climbing device 10. Preferably, the traction mechanism 200 has two groups, and the two groups of traction mechanisms 200 have four belt winding machines in total, and the two groups of traction mechanisms 200 are used for being more stable when the driving base 100 is lifted.
The workflow of the climbing device 10 is as follows:
firstly, after the ground is prepared, personnel send a hanging instruction to a climbing device through a remote control box at a place far away from a machine, and climbing starts to be automatically on line;
secondly, in the rising process, the microcomputer obtains compensation quantity through comparison and calculation according to attitude information returned by the gyroscope, and the rotation speed of the motor of each tape winder is automatically adjusted, so that the platform is kept in a relatively balanced state all the time in the rising process;
when the automatic balance rises to the fast-approaching cable a, one end of the machine approaching the cable a triggers the limit sensor, the microcomputer automatically controls the climbing motors on two sides of the end to stop after receiving the signal, the other end continues climbing until the climbing motors also trigger the limit sensor to stop, and the grooved wheel 520 of the wire hanging mechanism 500 is slightly higher than the cable a; then the telescopic rod 530 acts to turn the movable seat 510 forward, so that the grooved wheel 520 is opposite to the cable a;
after the movable seat 510 is in place, the software controls the motors of all the climbing belt winding machines to synchronously rotate reversely to form a climbing belt with a certain length, so that the groove of the grooved pulley 520 can be clamped into the cable a. At this time, the climbing operation can be completed.
The wire hanging frame 410 is hung on the ground or taken down through different combination modes of pulling the climbing belts on two sides on the cable a penetrating through the climbing belts. The specific wire hanging rack mounting mode is as follows:
firstly, designing a wire hanging frame 410 into a structural shape with a clamping groove;
secondly, after the climbing belt 400 penetrates into the wire hanging frame 410 according to a specific sequence, a specific side is pulled to the climbing belt by a traction rope to cross a cable (for example, an unmanned aerial vehicle is adopted);
thirdly, pulling the climbing belt on one side of the wire hanging frame 410 in the rising direction, releasing the wire hanging frame 410, allowing the wire hanging frame to rise to the height of the cable along with the climbing belt, then crossing the un-pulled side on the ground, and continuously pulling the climbing belt 400 on the rising direction, so that the wire hanging frame can be buckled into the cable a;
fourthly, in the operation process, the two ends of the climbing belt 400 are simultaneously stressed, so that the wire hanging rack 410 is ensured not to be separated from the cable;
after the operation is finished, the climbing belt is pulled reversely, so that the wire hanging frame can be pulled away from the cable, and therefore, the personnel can hang the wire hanging frame without going to the tower.
Meanwhile, the mechanism is also provided with a driving mechanism 540, and the mechanism capable of walking is arranged on the wire hanging mechanism 500, so that the mechanism can stably walk on different wire diameters of the overhead transmission line, has certain climbing capability and good cruising capability, and has good mechanical performance and low failure rate.
In addition, when the ionization of surrounding air by ultrahigh voltage enters an ionization range in the process of being on line and does not reach the equipotential state with a high-voltage transmission line, the high-voltage transmission line can carry out arc discharge on the conduction in the ionosphere range. In the arc discharge process, the generated high-voltage impact can directly damage electronic circuit components, and multiple harmonics generated by the high-voltage impact can interfere with the normal operation of a circuit and a power supply.
For this reason, the system also adopts the following structure: when the electric control equipment fast enters the high-voltage electric field range, the equipotential rod b is additionally arranged at the upper end of the device and is rapidly contacted with a high-voltage line, so that equipotential between the equipment and the high-voltage line is realized. At the moment, the device enters the electric field again, and the electric field can not discharge electric control equipment in the device, so that the normal operation of the electronic circuit is ensured. Alternatively, by ensuring good insulation between the circuit board and the wire and reducing the number of soldering points and branch points, the insulation protection must be enhanced at the positions where soldering or dimensional separation is necessary. The circuit board adopts multiple insulation measures, and after the circuit board is welded, the circuit board is packaged by epoxy resin, so that the electrostatic influence caused by dust adhesion can be reduced while the insulation performance is ensured. The metal aluminum shell with good conductivity is wrapped and shielded on the using space around the circuit board and the wires, so that the static potential difference of the wires and the periphery of the circuit board is eliminated, and the possibility of discharging of external metal bodies to the wires and the circuit board is reduced.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention as set forth in the claims appended hereto.
