Description

Technical Field

[0001] This utility model relates to the field of cable condition monitoring, and in particular to a cable condition monitoring device. Background Technology

[0002] As a critical carrier of electrical energy transmission in power systems, the operating status of cables directly determines the reliability and security of the power grid. With the expansion of power grid scale, the increase in service life, and the improvement of load density, problems such as cable aging, insulation defects, and external damage are becoming increasingly prominent, potentially leading to faults such as short circuits and breakdowns, causing large-scale power outages. Cable condition monitoring, by collecting cable operating data in real time or periodically and analyzing its health status, realizes "condition-based maintenance" to replace traditional "periodic maintenance," and is a core means of preventing faults, extending cable life, and reducing operation and maintenance costs.

[0003] Currently, high-altitude cables need to be monitored in a timely manner after prolonged use. The monitoring often involves people climbing to a high place and then visually observing the surface of the cable. This method is often accompanied by significant risks and cannot be carried out in strong winds or heavy rain. Due to the limitations imposed by weather conditions, a cable condition monitoring device is proposed to address the above problems. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a cable condition monitoring device, which integrates a lighting lamp, a monitoring camera and a marking pen in a movable frame. The lighting lamp provides supplementary lighting, the monitoring camera monitors the cable surface and transmits the image to a ground display screen for easy viewing. Once a defect is observed, the telescopic mechanism is controlled to move, which in turn moves the fixed cylinder, allowing the marking pen to mark the cable surface for timely and targeted maintenance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cable condition monitoring device, comprising a cable and a monitoring mechanism; The cable is equipped with a monitoring mechanism on its outer side for monitoring the cable surface; The monitoring mechanism includes movable frames arranged vertically, with the two sets of movable frames connected by a hinge assembly. Each movable frame is equipped with a telescopic mechanism, lighting, and a monitoring camera. The free end of the telescopic mechanism is fixedly connected to a fixed cylinder, and a marking pen is fixedly connected inside the fixed cylinder.

[0006] Furthermore, each of the movable frames is fixedly connected to a symmetrically arranged fixed shaft, and each of the fixed shafts is fixedly connected to a first guide wheel, the outer side of which is in contact with the cable.

[0007] Furthermore, a connecting plate is fixedly connected to the front side of the upper movable frame, and a fixing screw is provided below the connecting plate. The fixing screw passes through the connecting plate and is spirally connected to the movable frame.

[0008] Currently, high-altitude cables require timely monitoring after prolonged use. Inspections often involve manual climbing to a high point and visually inspecting the cable surface. This method is inherently risky and cannot be performed in strong winds or heavy rain. To address this limitation, a new approach is to install movable frames distributed vertically around the cable. These frames integrate lighting, monitoring cameras, and marking pens. The lighting provides supplemental illumination, while the cameras monitor the cable surface and transmit the images to a ground display screen for easy viewing. Once defects are detected, a telescopic mechanism moves, causing a fixed cylinder to move, allowing the marking pen to mark the cable surface for timely, targeted repairs.

[0009] A horizontal plate is fixedly connected to one side of the movable frame, and a connecting frame is fixedly connected to the other end of the horizontal plate. A motor is fixedly connected to the outside of the connecting frame, and a second guide wheel is fixedly connected to the end of the motor's main shaft.

[0010] Furthermore, there are two sets of horizontal panels, and each horizontal panel is fixedly connected by a connecting strap.

[0011] Furthermore, a connecting rod is fixedly connected to the bottom of the lower horizontal plate, and a counterweight is fixedly connected to the bottom of the connecting rod.

[0012] Furthermore, a second guide wheel that contacts the cable is provided on the opposite side of the horizontal plate. The device can move on the cable surface by rotating the second guide wheel driven by the motor. At the same time, the connecting rod and counterweight block are provided to provide counterweight and ensure stable movement of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By installing movable frames arranged vertically on the outside of the cable, and integrating lighting, monitoring cameras, and marking pens into the movable frames, supplementary lighting is provided, and the monitoring cameras monitor the cable surface and transmit the images to a ground display screen for easy viewing by personnel. Once a defect is observed, the telescopic mechanism is controlled to move, which in turn moves the fixed cylinder, allowing the marking pen to mark the cable surface for timely and targeted repairs. Furthermore, a second guide wheel that contacts the cable is provided on the opposite side of the horizontal plate. The device can move on the cable surface by rotating the second guide wheel driven by the motor. At the same time, the connecting rod and counterweight block are provided to provide counterweight and ensure stable movement of the device. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] Example A cable condition monitoring device, such as Figure 1-3 As shown, Includes cable 1 and monitoring unit 2; A monitoring mechanism 2 for monitoring the surface of cable 1 is provided on the outside of cable 1; Monitoring mechanism 2 includes movable frames 201 arranged vertically. The two sets of movable frames 201 are rotatably connected by a hinge assembly. Each movable frame 201 is equipped with a telescopic mechanism 202, a lighting lamp 203, and a monitoring camera 204. The free end of the telescopic mechanism 202 is fixedly connected to a fixed cylinder 207, and a marker pen 208 is fixedly connected inside the fixed cylinder 207.

[0018] The movable frame 201 is fixedly connected to symmetrically arranged fixed shafts 205 inside each frame, and the outer side of each fixed shaft 205 is fixedly connected to a first guide wheel 206. The outer side of the first guide wheel 206 is in contact with the cable 1.

[0019] A connecting plate 209 is fixedly connected to the front side of the upper movable frame 201. A fixing screw 210 is provided below the connecting plate 209. The fixing screw 210 passes through the connecting plate 209 and is spirally connected to the movable frame 201.

[0020] Currently, high-altitude cables require timely monitoring after prolonged use. Inspections often involve manual climbing to a high point and visually observing the cable's surface. This method is inherently risky and cannot be performed in strong winds or heavy rain. To address this limitation, a movable frame 201, arranged vertically, is installed on the outside of the cable 1. This frame integrates a lighting fixture 203, a monitoring camera 204, and a marking pen 208. The lighting fixture 203 provides supplementary illumination, while the monitoring camera 204 monitors the cable 1 surface and transmits the image to a ground display screen for easy viewing. The display screen integrates a control unit for controlling the device's movement and marking actions, and is wirelessly connected to the equipment. When a defect is observed, the telescopic mechanism 202 is moved, causing the fixed cylinder 207 to move, facilitating marking of the cable 1 surface with the marking pen 208. This allows for timely and targeted repairs. Also includes the following: The telescopic mechanism 202 uses an electric telescopic rod to drive the fixed cylinder 207 to move, while the first guide wheel 206 is in contact with the cable 1 to ensure stable movement of the device. When the movable frame 201 rotates, it can be easily fixed on the upper and lower sides of the movable frame 201 by the cooperation of the connecting plate 209 and the fixing screw 210.

[0021] A horizontal plate 3 is fixedly connected to one side of the movable frame 201, and a connecting frame 7 is fixedly connected to the other end of the horizontal plate 3. A motor 8 is fixedly connected to the outside of the connecting frame 7, and a second guide wheel 9 is fixedly connected to the end of the main shaft of the motor 8.

[0022] There are two sets of horizontal plates 3, and each horizontal plate 3 is fixedly connected by a connecting strap 4.

[0023] A connecting rod 5 is fixedly connected to the bottom of the horizontal plate 3 below, and a counterweight 6 is fixedly connected to the bottom of the connecting rod 5.

[0024] Furthermore, a second guide wheel 9 is provided on the opposite side of the transverse plate 3 to contact the cable 1. The device can move on the surface of the cable 1 by rotating the second guide wheel 9 driven by the motor 8. At the same time, the connecting rod 5 and the counterweight 6 serve as counterweights to ensure the stable movement of the device. The connecting strap 4 can fix the horizontal plate 3, preventing it from deforming during long-term use and causing the second guide wheel 9 to fail to contact the cable 1, thus affecting the movement of the equipment. In addition, a friction layer is provided on the inner side of the second guide wheel 9 to increase the friction with the cable 1 and ensure that the equipment moves smoothly. The control circuits between the devices are existing technology, so they will not be described in detail here.

[0025] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
