[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for maintaining and inspecting existing overhead wires, particularly overhead ground wires (GW).

0002

[Prior Art] Conventionally, damage caused by disconnected wires on overhead power transmission lines, etc.
Judgments are made by visual inspection while looking directly at the track, recording by a self-propelled video camera, and automatic detectors using electromagnetic induction.

[0003] Current methods of dealing with accident points discovered using these methods include winding armor grips by hoisting the vehicle after the inspection is completed, or, in the worst case, replacing overhead wires.

0004

[Problem to be solved by the invention] Conventional maintenance of power transmission lines,
The problems with inspection work are as follows. As mentioned above, various devices have been proposed for determining damaged parts of power transmission lines, but none of them have the ability to only detect damaged parts and repair the power lines at the same time based on the inspection results. Ta. As a result, the series of tasks of inspecting overhead power lines and then repairing them was extremely time-consuming.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an apparatus that solves the above-mentioned drawbacks of inspection work and automatically performs consistent work from damage detection to repair.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the automatic damage detection/repair device for overhead electric wires of the present invention is provided with a self-propelled body running along the overhead electric wires. It is necessary to repair the damage detection device that detects damage, the video camera that takes pictures of the damage situation when damage is detected by the damage detection device, and the image transmitter that sends images of the damage situation to the ground station. The radio device receives the repair command sent from the ground station when the repair command is determined, and when the repair command is received, the damage detected by the damage detection device is applied with reinforcing means such as armor rods to repair the overhead power line. The structure is equipped with a damage repair device.

[0007]

[Operation] When damage to an overhead power line is detected by the damage detection device, the damage situation is photographed by a video camera and sent to the ground station by an image transmitter. When the ground station determines that repairs are necessary, it transmits a repair command by radio. A repair command sent from the ground station is received by a radio, and a damage repair device is activated to apply reinforcing means such as an armor rod to the detected damaged area and repair the overhead power line. Therefore, the work from detection of damaged parts to repair can be performed consistently, and the efficiency of overhead electric wire maintenance is greatly improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

In FIGS. 1 and 2, an overhead power transmission line 1
A self-propelled body 20 is suspended by a pair of pulleys of a drive unit 3 and runs along an overhead power transmission line 1. This self-propelled body 20 includes a damage detection device 4 that detects damage such as a broken wire portion 2 in the middle of the span of the overhead power transmission line 1, and a damage detection device 4 that detects damage such as a broken wire portion 2 of the electric wire 1 in conjunction with this. It is equipped with a damage repair device 5 for repair, and further includes a control CPU 6, a power source 7, an image transmitter 8, a video camera 10,
11 (monitor device) and a radio device 12 are also installed.

[0010] The damage detection device 4 applies light to the surface of the overhead power transmission line 1 and uses the property of diffuse reflection when there is a change in shape to estimate the presence or absence of a wire breakage. However, other known detection devices can also be used.

Although not shown, the damage repair device 5 includes an armor rod magazine and a winding mechanism that automatically winds the armor rod in the magazine around the broken wire.

Of the two video cameras 10 and 11, the video camera 10, which is installed in front of the detection coil of the damage detection device 4 when viewed in the direction of travel, is for photographing the state of damage to the overhead power transmission line 1. is sent to the ground station by the image transmitter 8 and reproduced on a television monitor (not shown). Also, a video camera 11 installed behind the winding mechanism of the damage repair device 5 is used for monitoring the state after repair, and similarly, the image is sent to the ground station by the image transmitter 8 and played back on a television monitor. .

The radio device 12 is for wirelessly operating the drive section 3 and damage repair device 5 of the self-propelled body 20 from the ground station, and is capable of moving the self-propelled body 20 forward, marching, stopping, and repairing damage by wireless communication. The operation of the winding mechanism of the device 5 is controlled.

Next, the operation of the above configuration will be explained. Here, FIG. 1 shows the situation before operation, and FIG. 2 shows the situation after operation.

First, in FIG. 1, the self-propelled body 20 is self-propelled by the drive unit 3 along the overhead power transmission line 1 from the left hand to the right hand in the figure. If there is a broken wire portion 2 on the overhead power transmission line 1 at this time, the damage detection device 4 detects this, and the CPU 6 temporarily stops the traveling of the self-propelled body 20 based on the detection signal. Here, the CPU 6 monitors the damage situation of the broken wire section 2 using a video camera 10.
The image is sent to the ground station by the image transmitter 8 and reproduced on a television monitor.

[0016] Here, the worker monitoring the television monitor at the ground station determines whether or not repairs are necessary based on the damage situation. When it is determined that there is no need for repair, the worker sends a wireless operation signal and continues to run the self-propelled body 20. On the other hand, when repair is necessary, a repair command to operate the repair device 5 by wireless operation is sent to the radio device 12 of the self-propelled body 20.
send to When receiving this repair command, the CPU 6 operates the damage repair device 5. Thereby, the damage repair device 5 takes out the armor rod from the magazine, automatically wraps it around the broken wire portion 2 using the winding mechanism, and automatically repairs the damaged portion.

The state of the repair is captured by a video camera 11 and checked on a television monitor at the ground station. After the repair is completed, the worker again issues a forward command using a wireless operation signal, causes the self-propelled body 20 to start traveling, and continues to inspect the overhead power transmission line 1.

[0018] In this way, everything from detecting damaged parts of electric wires to repairing them can be carried out consistently with one device, which is safer and has better workability than inspection and repair work using conventional spacecraft. .

[0019] In the above embodiments, the repair device was only described as wrapping around the armor rod, but the repair device may also be constructed by reinforcing means such as compression using a sleeve or hardening strong adhesive to wrap around the entire damaged area. You can also apply In addition, although two video cameras 10 and 11 are installed, only one video camera 10 is installed, and the video camera 11 is installed.
This function can also be used by the video camera 10 by backing up the self-propelled body 20 after repairing damage.

[0020]

[Effects of the Invention] In summary, according to the present invention, one device consistently performs everything from detecting damaged parts of overhead power lines to repairing them, which improves workability and greatly improves the efficiency of overhead power line maintenance. be able to. In addition, safety is improved because there is no need for inspections and repairs by workers riding in the air, which was conventionally done.
