[0002] In high-voltage transmission networks, ice can pose a significant threat to transmission lines. Thick ice can, at best, cause the lines to snap, leading to power outages, or even rip the power rails, causing even greater damage. Therefore, measuring the thickness of ice on transmission lines is essential to support overall power grid monitoring.

This device has the same shortcomings as the existing ice thickness detection device when in use: the device needs to be fixed with bolts, and the detection of ice requires high-altitude work, which makes the installation of the device more troublesome and prone to bolts falling, and is not quick and convenient to use; secondly, the device can only detect the ice thickness at a single position on the wire surface. If you want to detect another place, you need to disassemble the device and change the position.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figures 1-4 The utility model provides an embodiment: a device for detecting the thickness of ice coating on electric wires, comprising a base 1 and a top base 2, an arc-shaped slot 3 for passing the electric wires is provided on the lower surface of the top base 2, a vertical plate 4 is fixed to one side of the upper surface of the base 1, and a movable slot 41 is provided at the middle part of the top of the vertical plate 4, a connecting component 5 is fixed between the inside of the movable slot 41 and the lower surface of the top base 2, a plurality of rolling components 6 are provided on the inner side wall of the arc-shaped slot 3, a cavity 7 is provided inside the base 1, a laser rangefinder 8 is passed through and fixedly connected to the top wall of the base 1, a battery module 10 and a data storage module 9 are fixedly installed inside the cavity 7, the laser rangefinder 8 is electrically connected to the data storage module 9, an inspection cover 11 is fixed to one side of the cavity 7 by bolts, and a traction component 12 is installed on the lower surface of the base 1.

[0028] The connecting assembly 5 includes a tension spring 51 fixed to the inner bottom wall of the movable groove 41 , the top of the tension spring 51 is fixedly connected to a movable rod 52 , and the movable rod 52 is slidably connected to the movable groove 41 , and the top of the movable rod 52 is fixedly connected to the lower surface of the top seat 2 .

[0029] A locking bolt 53 passes through and is threadedly connected to the top side wall of the movable groove 41 .

[0030] In this embodiment, the base 1 and top 2 are elastically connected via the connecting assembly 5. Therefore, when installing the device, the base 1 and top 2 are first pulled in opposite directions, at which point the tension spring 51 is in a stretched state. The arc-shaped slot 3 is then engaged with the surface of the ice-covered wire. The base 1 and top 2 are then released. Under the tension of the tension spring 51, the top 2 re-aligns with the vertical plate 4 on the surface of the base 1. The locking bolt 53 is then tightened to secure the movable rod 52, thereby securing the device to the wire. This makes installation of the device simple and quick.

[0031] A charging data port is installed on the surface of the inspection cover 11 , the battery module 10 and the data storage module 9 are both electrically connected to the charging data port, and the laser rangefinder 8 and the data storage module 9 are both electrically connected to the battery module 10 .

[0032] In this embodiment, laser rangefinder 8 measures the distance from itself to the lower surface of the ice-covered wire, which is set to h. Data storage module 9 stores the data measured by laser rangefinder 8 at specified intervals. The data stored in data storage module 9 can be subsequently downloaded via a USB flash drive connected to the charging data port. Furthermore, the charging data port charges battery module 10, which in turn provides power to laser rangefinder 8 and data storage module 9.

[0033] When the top seat 2 is completely in contact with the vertical plate 4, the laser rangefinder 8 measures the distance from itself to the top of the arc slot 3 as d. When the device is installed on the surface of the wire, the laser rangefinder 8 measures the distance from itself to the bottom of the ice on the wire surface as h. Assuming the diameter of the wire is a, the formula for calculating the ice thickness is: k (ice thickness) = (dha) / 2.

[0034] The traction assembly 12 includes a triangular rod 121 hinged to the lower surface of the base 1 , and a pull rope 122 is fixedly connected to the bottom end of the triangular rod 121 .

[0035] Since the device is not directly fixed on the surface of the wire, the device can be pulled along the surface of the wire by the pull rope 122, which is conducive to measuring more data and facilitating subsequent analysis.

[0036] The rolling assembly 6 includes a groove 61 formed on the inner wall of the arc-shaped slot 3 , and a ball 62 is rotatably connected inside the groove 61 .

[0037] By setting the ball 62, the ball 62 can fit the ice on the surface of the wire, and because the ball 62 can rotate, the friction between the arc-shaped slot 3 and the surface of the wire can be reduced, and the pulling device moves more smoothly along the surface of the wire.

[0038] Working principle: First, pull the base 1 and the top seat 2 in opposite directions. At this time, the tension spring 51 is in a stretched state. Then, clamp the arc-shaped slot 3 on the surface of the wire with ice. Then, loosen the base 1 and the top seat 2. Under the tension of the tension spring 51, the top seat 2 and the vertical plate 4 on the surface of the base 1 are re-fitted. Then, tighten the locking bolt 53 to fix the movable rod 52, thereby fixing the device on the wire. Then turn on the laser rangefinder 8 to measure the data. Then, pull the device to move by pulling the rope 122 to measure more data. After the data measurement is completed, loosen the locking bolt 53 and pull away from the base 1 and the top seat 2 to remove the device from the surface of the wire. After downloading the data, the thickness of ice at different positions on the wire can be calculated using the above formula.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
