Description

Technical Field

[0001] The present invention belongs to the technical field of protection for electric power construction, and in particular relates to a safety protection structure for an electric power tower and an operating method thereof. Background Art

[0002] With the development of the electric power industry, high-altitude high-voltage transmission lines have become indispensable equipment. High-voltage transmission lines are mainly erected in the air through power towers to keep a specified safe distance from the ground or crossing objects. The height is mostly 15-20 meters. The voltage of the transmission lines is mostly 110KV, 220KV, 330KV, and 500KV. my country has built more than 50,000 kilometers of 300KV and 500KV transmission lines.

[0003] High-altitude high-voltage transmission lines can operate normally at 5-50℃. In special climatic conditions, sudden snowstorms or rain and snow, the temperature fluctuates between 0 and -40℃, and ice often forms on the transmission cables. The ice will accumulate more and more, greatly endangering the operation safety of the high-voltage lines. The diameter of high-voltage cables is mostly 10-30mm. The accumulation of ice will make the cables overwhelmed and even pull the power tower to topple, causing major and extremely serious power outages, and even causing the entire transmission line to be paralyzed. Deicing of high-altitude high-voltage cables in cold zones or winter has become a very important research topic.

[0004] Based on this problem, a Chinese invention patent with publication number: CN101420110A discloses a percussion de-icer for power transmission cables. The left and right running wheels are connected by pulleys and belts. The left and right running wheels are provided with left and right percussion arms and percussion hammers. A left and right reversing switch is provided in the middle of the main board, which can simultaneously drive the left and right percussion hammers to perform cross-circular percussion actions. The percussion hammers mainly percuss one side of the cable to remove the accumulated ice cones. However, in actual operation, we found that it is difficult to completely remove ice by percussing one side of the cable. The residual ice debris can easily re-freeze and may also form ice cones, posing a potential safety hazard. Summary of the invention

In this way, the forces on both sides of the fixing frame 1 are more balanced during the de-icing process, and the connection between the fixing frame 1 and the power tower is more stable. At the same time, the two groups of de-icing components de-ice the cables on both sides of the power tower at the same time, thereby improving the de-icing efficiency.

[0137] Example 9

[0138] This embodiment discloses an operation method of a safety protection structure for a power tower, which is applicable to the safety protection structure for a power tower in the above-mentioned embodiment, and includes the following steps:

[0139] X1. Installation: Install the fixing frame 1 on the power tower, place the de-icing assembly close to the cable, put the ring sleeve 4 on the outside of the cable, and keep the extension unit 2 in the original position;

[0140] X2. Deployment of the crushing element 5: Start the adjusting motor 907 to drive the adjusting gear 904 to rotate, and the adjusting gear 904 drives the locking rod 905 to move so that the second end of the locking rod 905 withdraws from the locking groove 9012, and start the auxiliary motor 802 to drive the transmission gear 902 to rotate, and the transmission gear 902 drives the transmission gear ring 901 to rotate, and the transmission gear ring 901 drives the auxiliary gear ring 801 to rotate, thereby driving the adjusting ring 601 to rotate so that the adjusting rod 602 moves from the first end to the second end of the crushing element 5, and then the second end of the crushing element 5 swings toward the inner side of the ring sleeve 4 until it contacts the surface of the ice layer;

[0141] X3. De-icing: Start the main drive unit 7 to drive the ring sleeve 4 to rotate, so that the crushing piece 5 breaks the ice layer on the surface around the circumference of the cable. During the crushing process, start the extension unit 2 to extend, so that the mounting frame 3 moves with the ring sleeve 4 away from the power tower, so that the ring sleeve 4 can move along the length direction of the cable, and the surface of the cable is de-iced in turn. During this process, the locking rod 905 is inserted into the locking groove 9012 to limit the rotation of the transmission gear ring 901. When the extension unit 2 reaches the longest position, start the adjustment motor 907 to make the locking rod 905 withdraw from the locking groove 9012, start the auxiliary motor 802 to make the second end of the crushing piece 5 swing toward the inside of the ring sleeve 4 again, increase the thickness of the de-icing, and then start the extension unit 2 to shorten, so that the mounting frame 3 moves with the ring sleeve 4 towards the power tower, and de-ices the cable more deeply;

[0142] X4. Storage: After de-icing is completed, adjust the extension unit 2 to the shortest length, start the auxiliary motor 802 to move the adjustment ring 601 from the second end of the crushing member 5 to the first end, and then swing the second end of the crushing member 5 to the outside of the ring sleeve 4 to separate the crushing member 5 from the cable. At this time, start the adjustment motor 907 to clamp the locking rod 905 into the locking groove 9012 to limit the rotation of the transmission gear ring 901.

[0143] In this embodiment, in step X1, the ring sleeve 4 can be designed to be a splicable structure, which is convenient for the first time to connect the ring sleeve 4 to the outside of the cable. The original position of the extension unit 2 can be understood as the position where the length of the extension unit 2 is the smallest. During the entire installation process of the safety protection structure, the locking rod 905 is stuck in the locking groove 9012 to limit the position change of the crushing member 5 and ensure the safety of the workers; in step X2, the second end of the crushing member 5 contacts the surface of the ice layer, which is actually the crushing blade at the second end of the crushing member 5 contacts the surface of the ice layer, and the crushing blade may also partially penetrate the ice layer; in step X3, a single-stroke or reciprocating movement of the extension unit 2 to extend and shorten is used as a deicing operation. After a deicing operation, the radial position of the crushing member 5 in the ring sleeve 4 can be adjusted by the adjustment unit 6, so as to perform deeper deicing, and the ice layer on the cable surface is completely removed by reciprocating in this way.

[0144] In this embodiment, the maximum radial adjustment distance of the second end of the crushing member 5 and the distance of each adjustment are preset by the operator. The ring sleeve 4 has a certain length, and the cable can be positioned first to ensure that the cable surface will not be damaged when the ring sleeve 4 drives the crushing member 5 to move.
