[0021] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] To address the issues of complex and costly DC de-icing technology, which often necessitates manual de-icing with low efficiency, this invention provides a high-voltage transmission tower with de-icing functionality. The tower features a first mounting frame and a drive motor. A second mounting frame is mounted on the first frame, comprising a vertically arranged cable mounting section and a winch mounting section. A cable is mounted on the winch and positioned between adjacent towers, perpendicularly aligned with the corresponding cable. A de-icing device is fixedly mounted on the cable and movably fitted onto the corresponding cable. When de-icing is required, the drive motor activates the winch, which in turn moves the cable, causing the de-icing device to move along the cable, thus achieving de-icing. This mechanical de-icing method eliminates the need for power outages, is simple and effective, and ensures continuous power supply.

[0026] The drive motor can draw power from the mains power grid, or the high-voltage tower can also be equipped with mains power transmission cables. The drive motor can draw power directly from the mains power transmission cables on the tower, and the simultaneous installation of mains power transmission cables on the high-voltage tower can also improve the economic efficiency of the power system.

[0027] Specifically, please refer to Figure 1 and Figure 2 In this embodiment, a first mounting bracket 21 is provided on the tower 10. The first mounting bracket 21 extends laterally out of the tower 10 to facilitate the arrangement of the cable 101. A drive motor (not shown in the figure) is provided on the first mounting bracket 21. The drive motor is located inside the protective shell 241. The protective shell 241 is fixed on the tower 10 or fixed on the first mounting bracket 21.

[0028] A second mounting frame is provided on the extension of the first mounting frame 21. The second mounting frame includes a vertically arranged cable mounting part 231 and a winch mounting part 232. The cable 101 is mounted on the cable mounting part 231, and a winch 230 is provided on the winch mounting part 232. The winch 230 is connected to a drive motor. A cable 201 is provided on the winch 230. The cable 201 is arranged between the winches 230 of adjacent towers 10 so as to be aligned and vertically arranged with the corresponding cable 101.

[0029] A de-icing device 22 is fixedly installed on the cable 201, and the de-icing device 22 is also movably sleeved on the corresponding cable 101. When the winch 230 rotates, the cable 201 is dragged, which can drive the de-icing device 22 to slide on the cable 101, thereby removing the ice layer on the cable 101. The drive motors on each tower 10 operate synchronously so that the winches 230 at both ends of the cable 201 rotate synchronously. The transmission from the drive motor to the winch can be achieved through bevel gears.

[0030] When the cable 201 is driven by the pull, it can be coiled and released on the winch 230. The coiling and releasing actions can remove the ice layer on the cable 201 simultaneously.

[0031] To further improve the de-icing effect, in this embodiment, the first mounting bracket 21 is also provided with a sliding groove along the extension direction of the first mounting bracket 21. The second mounting bracket is slidably disposed in the sliding groove. The second mounting bracket is also connected to the drive motor through a crank-connecting rod mechanism 25. When the cable 201 is dragged, the second mounting bracket can also be driven to move laterally through the crank-connecting rod mechanism 25, which can drive the cable 101 fixed on the second mounting bracket to shake. The shaking action can break the solidified ice layer on the cable 101 into small pieces, avoiding the whole ice layer from hindering the movement of the de-icer 22, improving the mobility of the de-icer 22, and ensuring the reliability of de-icing.

[0032] To ensure the effectiveness of the swaying cable 101, the tower includes alternating first-class and second-class towers. A first mounting bracket with a groove, a crank connecting rod mechanism, and a corresponding second mounting bracket are set in the first-class tower. That is, the movable second mounting bracket and the fixed second mounting bracket are alternately set so that one end of each section of cable 101 is fixed and the other end is movable, thereby realizing the swaying action.

[0033] To ensure the stability of the cable 101, it is generally fixed at multiple points on the tower. Correspondingly, in this embodiment, fixing rings are provided at both ends of the cable mounting part 231, and the cable is fixed at two points.

[0034] To achieve de-icing of both the front and rear cable sections, in practical applications, one winch 230 is installed at the front and one at the rear along the arrangement direction of the cable 101, respectively, for dragging the front and rear cable sections. This avoids the impact of fixing a single cable section on other areas and improves reliability.

[0035] In an optional embodiment, the cable 201 can be led out from both ends of the winch 230 and led out forward and backward respectively, so that each section of the cable 201 can be connected as a whole, which facilitates the synchronous reciprocating drive of the entire line cable during de-icing.

[0036] To ensure the reliability of cable 201 coiling and releasing on winch 230 and to avoid misalignment, in this embodiment, a limiting frame 234 is also provided on the second mounting frame. The limiting frame 234 is spaced apart from the winch 230, and cable 201 is set through the limiting frame 234. A limiting section can be formed between the limiting frame 234 and the winch 230 to prevent cable 201 from deviating from the position of the winch 230 and winding on the side shaft, thereby improving the reliability of cable 201 coiling and releasing.

[0037] To facilitate the installation of the de-icer 22, in this embodiment, as follows: Figure 3 As shown, the de-icing device 22 includes a fixed block 221 and an insulating sleeve 222 that are fixedly connected. The fixed block 221 is fixedly mounted on the cable 201. The insulating sleeve 222 is a split sleeve so that it can be molded and installed on the cable 101. After molding, it can be fixed with screws.

[0038] The high-voltage transmission tower with de-icing function provided by this utility model is equipped with a first mounting frame and a drive motor on the tower. A second mounting frame is installed on the first mounting frame. The second mounting frame includes a vertically arranged cable mounting part and a winch mounting part. A cable is installed on the winch and is arranged between adjacent towers, perpendicularly aligned with the corresponding cable. A de-icing device is fixedly installed on the cable and is movably sleeved on the corresponding cable. When de-icing is required, the drive motor is controlled to drive the winch, which moves the cable and thus moves the de-icing device on the cable to achieve de-icing. This can effectively achieve automatic de-icing of the cable and improve de-icing efficiency. The mechanical de-icing does not require power outages, is simple and effective to operate, and can ensure the continuity of power supply.
