Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable de-icing technology, and more specifically, to a de-icing device for power transmission cables in power engineering. Background Technology
[0002] In power engineering, transmission cables are susceptible to ice and snow in winter and cold regions. Ice accumulation increases the load on cables, affects transmission safety, and can even lead to line faults. Therefore, the design and application of de-icing devices are particularly important. During the de-icing process, cable de-icing devices are used to remove ice from the cable surface. The de-icing device moves on the cable surface to remove the ice from the cable surface. Since the configuration of the de-icing device directly affects its working stability, it is necessary to perform de-icing counterweight operation on the de-icing device.
[0003] In related technologies, during the use of de-icing devices, the de-icing device is generally driven by a motor or small motor to move on the surface of the cable and drive the de-icing components to work, thereby removing the ice covering the cable surface for use.
[0004] However, in the current use of de-icing devices, because the cables are cylindrical and flexible, while the counterweight of the de-icing device is fixed, the counterweight is often insufficient during de-icing. This causes the de-icing device to swing on the cable surface, or even swing excessively and separate from the cable and fall off, affecting the counterweight adaptability and working stability of the de-icing device.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Reference Figures 1-4This utility model provides a technical solution: a de-icing device for power transmission cables, including a de-icing machine body 1 and a de-icing counterweight mechanism. A de-icing shaft 2 is installed on the left side of the de-icing machine body 1, and a de-icing disc 3 is installed on the left side of the de-icing shaft 2. This provides a medium for users to install counterweights on the outside of the de-icing machine body 1, and facilitates users to adjust the counterweight according to the actual working conditions of the de-icing machine body 1. This avoids the situation where it is difficult to adjust the counterweight during use, resulting in insufficient counterweight force and unstable operation of the de-icing machine body 1. Therefore, it improves the counterweight adaptability and working stability of the de-icing machine body 1.
[0031] Reference Figures 1-4 In a preferred embodiment, the de-icing counterweight mechanism includes a counterweight base 4, which is movably connected to both sides of the de-icing machine body 1. Counterweight frames 5 are movably connected to both sides of the interior of the counterweight base 4. A counterweight hook 6 is fixedly connected to the bottom of the counterweight base 4, and a counterweight rod 7 is movably connected to the outer side of the counterweight hook 6. A counterweight ring 8 is movably connected to the surface of the counterweight rod 7, and a counterweight blocking mechanism is movably connected to the bottom of the counterweight rod 7. The counterweight base 4, in conjunction with the counterweight frames 5 and the counterweight hook 6, allows the counterweight rod 7 to be installed on both sides of the de-icing machine body 1. The number of counterweight rings 8 installed is adjusted according to the actual working counterweight requirements of the de-icing machine body 1, so that the counterweight rings 8 cooperate with the counterweight rod 7. The de-icing machine body 1 is counterweighted to ensure its stability when working with the de-icing disc 3. The counterweight blocking mechanism includes a blocking plate 9, a blocking hole 10, and a blocking frame 11. The blocking plate 9 is movably connected to the bottom of the counterweight rod 7, the blocking hole 10 is opened at the bottom of the blocking plate 9, and the blocking frame 11 is movably connected inside the blocking hole 10. The top of the blocking frame 11 is fixedly connected to the bottom of the counterweight rod 7. This mechanism can prevent the counterweight ring 8, which is adjusted and installed on the outside of the counterweight rod 7, from detaching from the counterweight rod 7, thus avoiding the difficulty in installing the counterweight ring 8 after adjustment and installation. This improves the stability and convenience of installing the counterweight ring 8.
[0032] Reference Figures 2-4 In a preferred embodiment, by embedding a disk 12 at the top of the barrier plate 9 and embedding a magnetic chuck 13 at the bottom of the counterweight rod 7, which is magnetically connected to the disk 12, magnetic positioning can be achieved between the barrier plate 9 and the counterweight rod 7, avoiding the difficulty of positioning the barrier plate 9 during use. This improves the ease of positioning the barrier plate 9. A positioning cylinder 14 is fixedly connected to the inner side of the counterweight hook 6, and a positioning post 15 that penetrates the counterweight hook 6 is movably connected inside the positioning cylinder 14. This provides the user with a medium for positioning the counterweight rod 7 and the counterweight hook 6, thus improving the ease of fixing the counterweight rod 7 and the counterweight hook 6.
[0033] Reference Figures 2-4In a preferred embodiment, a positioning groove 16 is provided at the top of the inner side of the counterweight rod 7, and a positioning hole 17 communicating with the positioning groove 16 is provided inside the counterweight hook 6. The positioning post 15 is located inside the positioning hole 17 and the positioning groove 16, which can provide space for the positioning post 15 to perform insertion and positioning between the counterweight rod 7 and the counterweight hook 6, thus improving the positioning effect of the positioning post 15. A magnetic ring 18 is embedded and connected to the inner wall of the positioning hole 17, and a magnetic cylinder 19 magnetically connected to the magnetic ring 18 is embedded and connected to the surface of the positioning post 15, which can perform magnetic attraction positioning and anti-separation work between the positioning post 15 and the positioning groove 16, thus improving the insertion and positioning stability of the positioning post 15.
[0034] Reference Figures 2-4 In a preferred embodiment, a screw groove 20 is provided on the outer side of the counterweight hook 6, and a bolt 21 located on the outer side of the counterweight rod 7 is connected to the screw groove 20 internally. This can stabilize the connection between the counterweight rod 7 and the counterweight hook 6, thus improving the connection stability between the counterweight rod 7 and the counterweight hook 6. A screw cavity 22 is provided on the inner side of the counterweight frame 5, and a double-ended stud 23 is connected to the screw cavity 22 internally. This can provide the user with a medium for synchronously moving the counterweight frame 5 for clamping, thus improving the convenience of clamping operation of the counterweight frame 5.
[0035] Specifically, the working process or working principle of this power transmission cable de-icing device is as follows: During use, the counterweight base 4 is moved to the outside of the de-icing machine body 1, and the counterweight frame 5 is positioned on the outside of the de-icing machine body 1. Then, the double-ended stud 23, in conjunction with the screw cavity 22, applies a synchronously moving threaded thrust to the counterweight frame 5 on both sides inside the counterweight base 4, causing the inner side of the counterweight frame 5 to contact and press firmly against the surface of the de-icing machine body 1. This clamps and installs the counterweight base 4 and the de-icing machine body 1, causing the counterweight base 4, in conjunction with the counterweight hook 6, to install the counterweight rod 7 on the de-icing machine body. On the outside of the machine body 1, bolt 21 engages with screw groove 20 to connect and stabilize the counterweight rod 7 and counterweight hook 6. Then, according to the actual counterweight requirements of the de-icing machine body 1, the counterweight ring 8 is aligned with the counterweight rod 7 and moved upwards to fit over the outside of the counterweight rod 7, adjusting the counterweight of the counterweight ring 8. After the counterweight ring 8 is fitted over the counterweight rod 7, the barrier plate 9 is rotated to offset the through holes inside the counterweight ring 8, preventing separation between the counterweight ring 8 and the counterweight rod 7. At this time, the barrier frame 11 is in the barrier hole 10. Internal rotation allows for direct rotational connection between the baffle plate 9 and the counterweight rod 7. Simultaneously, the disk 12, in conjunction with the magnetic chuck 13, magnetically positions and stabilizes the baffle plate 9 and counterweight rod 7 after rotation. When the de-icing machine body 1, after the counterweight rod 7 and counterweight ring 8 have engaged, requires positioning of the counterweight rod 7, the handheld positioning post 15 is moved outwards, passing through the positioning hole 17, penetrating the counterweight hook 6, and entering the positioning groove 16. This allows for the insertion and positioning of the counterweight rod 7 and counterweight hook 6. When the de-icing machine body 1, after the counterweight rod 7 and counterweight ring 8 have engaged, requires... When the counterweight rod 7 swings, the hand-held positioning column 15 moves inward through the positioning hole 17 and disengages from the positioning groove 16, so that the matching rod and the counterweight hook 6 are in a rotating and swinging state. During this process, the magnetic ring 18 and the magnetic cylinder 19 perform magnetic attraction positioning and stabilization work between the moved positioning column 15 and the counterweight hook 6. When the de-icing machine body 1 drives the de-icing disc 3 to rotate through the de-icing shaft 2 to remove the ice on the surface of the cable, the counterweight rod 7 and the counterweight ring 8 perform de-icing counterweight stabilization work for the de-icing machine body 1 through the counterweight hook 6 and the counterweight seat 4.
[0036] It should be noted that the de-icing machine body 1, the de-icing shaft 2, and the de-icing disc 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail here.
