Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line operation and inspection, and more specifically, to an external damage early warning device utilizing a machine nest unmanned aerial vehicle for inspection. Background Art

[0002] In recent years, with the widespread application of technologies such as drone power inspection and mobile Internet, the difficulties of large manpower investment, high safety risks and low efficiency in power grid line operation and maintenance inspection have been solved to a certain extent. However, drones and mobile applications also have the following shortcomings: a lot of manpower is required for field inspection operations, the inspection cost is high, the inspection cycle is long, there is a shortage of personnel, and the equipment operation and maintenance management tasks are heavy.

[0003] Through further statistical analysis of transmission line faults, it was found that the direct causes of the faults can be summarized into the following two categories: external damage and equipment failure. More than half of the faults were caused by external damage, and the direct causes of frequent external force damage caused by external damage can be summarized into the following five categories: foreign body short circuit, mechanical construction, illegal construction, forest fire, and smoke short circuit. Since mechanical construction and illegal construction have overlapping intersections, the two are collectively referred to as construction-related external force damage. Tripping caused by construction-related external force damage and foreign body short circuit has accounted for 90% of external damage tripping, which is the main cause of external damage tripping.

[0004] At present, the monitoring system and early warning method for preventing power transmission line from external force damage mainly detects the on-site conditions through monitoring methods such as laser beam, infrared detection or ultrasonic detection. When an abnormal situation is detected, the video image monitoring equipment is activated to record the on-site activities and activate the on-site sound and light alarm device. However, since the distance between the two towers of the power transmission line is hundreds of meters, the existing monitoring methods have problems such as limited detection area and poor working reliability. For example, the laser beam method can only detect machinery approaching the line from a certain direction, and the monitoring range of infrared detection and ultrasonic detection is only tens of meters. Such monitoring methods cannot meet the requirements of wide-area detection. In addition, the alarm unit of the existing system is set on the tower, which is far away from the on-site construction vehicles, resulting in the warning effect of its sound and light alarm effect is not ideal. Summary of the invention

Through the equipment and algorithms carried by the inspection drone, high-quality image acquisition and processing can be performed on the scene, and accurate and timely warning information can be provided to relevant personnel, thereby improving the monitoring, warning and emergency response capabilities of external damage incidents, thereby protecting personnel safety, reducing losses, and improving the level of social security, thereby solving the problems raised in the above-mentioned background technology.

[0037] Second embodiment As attached Figure 1-4 ,6 is an embodiment of the present invention. By setting up the detection component 3, the unmanned aerial vehicle 21 can detect the cables on site. The detection component 3 is lifted by starting the unmanned aerial vehicle 21, and the detection frame 31 is placed on the surface of the cable so that the support wheels 34 on both sides of the detection frame 31 are located above the cable.

[0039] Among them, both ends of the bottom of the detection frame 31 are fixedly connected with water tanks 35, wherein the water tanks 35 not only store the marking solution, but also are arranged on both sides of the detection frame 31, so that the detection component 3 can move more smoothly on the cable, and a ring frame 37 is fixedly connected to one side of the water tank 35, and a nozzle 38 is arranged inside the ring frame 37, and the nozzle 38 is connected to the water tank 35 through a connecting pipe. By setting the nozzle 38, the marking solution inside the water tank 35 passes through the connecting pipe and is sprayed out from the nozzle 38. When the laser diameter gauge 36 detects that the outer surface of the cable is damaged, the marking solution inside the water tank 35 is sprayed through the nozzle 38 to mark the damaged part of the cable.

[0040] Third embodiment As attached Figure 1-6As one embodiment of the present invention, by setting a pushing cylinder 25 and a laser diameter gauge 36, when there is no need to inspect the cable, the pushing cylinder 25 is retracted, and the ring 28 pulls the connecting cable 24 to be clamped in the inside of the engaging groove 26, so that the detection frame 31 is close to the bottom of the drone body 21, and the electromagnet 27 adsorbs the magnet block 32 to make the detection component 3 fit to the bottom of the inspection drone 2, thereby maintaining the stability of the inspection drone 2 in flight.

At this time, the location information of the external damage scene is located through the visual monitoring device 41 and the three-dimensional point cloud ranging device.

At the same time, in order to facilitate the detection of the cable, the unmanned aerial vehicle 21 flies above the cable, the electromagnet 27 loses its magnetism, the mobile camera 23 is separated from the electromagnet 27, and the connecting cable 24 is drooped by pushing the cylinder 25 to extend, so that the detection component 3 is affected by gravity and droops and unfolds, and the detection frame 31 is placed on the surface of the cable, so that the support wheels 34 on both sides of the detection frame 31 are located above the cable, and the inspection drone 2 pulls the detection component 3 to move, so that the detection component 3 detects the outer surface of the cable and marks it, which is convenient for the inspection personnel to repair it, and at the same time, the inspection position is known at the first time, and the detection frame 31 is pulled by the movement of the unmanned aerial vehicle 21, so that the support wheels 34 rotate on the outer surface of the cable, and the integrity of the outer surface of the cable is detected by the laser diameter meter 36 to determine whether the cable is in a damaged state; When the laser diameter gauge 36 detects that the cable is damaged, the marking solution inside the water tank 35 is sprayed out from the nozzle 38 through the connecting pipe to mark the damaged part of the cable, so that the inspection personnel can quickly find the location of the damaged cable.
