A resistance-type transmission line wind-proof iron tower

Abstract

A resistance-type transmission line wind-proof iron tower relates to a wind-proof iron tower. In order to solve the problem that the existing transmission iron tower is a rigid tower and cannot effectively reduce the wind-proof energy, a resistance-type transmission line wind-proof iron tower is proposed. In the resistance-type transmission line wind-proof iron tower of the present invention, a resistance mechanism is provided between the tower head and the tower body, and the tower head and the tower body can rotate relative to each other. The resistance connecting piece provided in the resistance mechanism is a spring or a hydraulic connecting rod. The resistance connecting piece is symmetrically arranged to restore the relative rotation to the original position. When wind-proof occurs, the transmission line will cause the tower head and the tower body to rotate relative to each other after swinging, and the resistance connecting piece can offset the relative rotation torque. The relative rotation of the tower head and the tower body reduces the tension on the transmission line caused by wind-proof phenomenon, avoids the simultaneous resonance of the tower and the transmission line when wind-proof occurs, effectively reduces the wind-proof energy, and further ensures the safety of power supply.

Description

Technical Field

[0001] The invention relates to a windproof iron tower. Background Art

[0002] Ice-covered transmission lines often experience wind-driven galloping in weather conditions such as freezing and high winds. This galloping of ice-covered conductors poses a serious threat to the safe operation of transmission lines, easily causing phase-to-phase flashover, hardware damage, line tripping, power outages, or serious accidents such as conductor burns, tower downfalls, and conductor breakage, resulting in significant economic losses. Extensive research has been conducted domestically and internationally on the mechanisms and protections for ice-covered conductor galloping. Conductor galloping trajectories are simulated based on conductor galloping acceleration, and a transmission line conductor galloping monitoring system and a multi-point transmission line conductor galloping monitoring system based on wireless sensor networks have been studied. The optimal solution, a wind-driven galloping monitoring system for transmission line conductors, was developed. This system utilizes the principles of object movement and acceleration to monitor conductor galloping. Using digital signal processing, remote control, and wireless communication technologies, wireless sensor networks are deployed along the transmission lines to enable remote qualitative and quantitative analysis of conductor galloping. The galloping mechanism of transmission lines, along with relevant previous data, provides a basis for decision-making by power operators during critical periods. However, the above analysis or detection can only obtain real-time data and cannot fundamentally solve the problem of wind deviation of transmission lines.

[0003] Existing transmission towers primarily include angle steel towers, steel tube towers, steel tube and angle steel combination towers, and steel tube poles. Transmission towers include wine glass, cat head, up-shaped, dry-shaped, and barrel-shaped towers. However, these towers are mostly rigid, with a fixed vibration frequency, providing only support. When wind deflects a transmission line, they are prone to simultaneous resonance with the transmission line, failing to effectively mitigate wind deflection energy. Summary of the Invention

[0004] In order to solve the problem that the existing transmission tower is a rigid tower and cannot effectively reduce the wind deflection energy, the present invention proposes a resistance-type transmission line wind deflection-proof iron tower.

[0005] The resistance-type transmission line wind-proof iron tower of the present invention comprises a tower base (1), tower legs (2), a tower body (3), a tower head (4), a conductor (6), an insulator (5) and a resistance mechanism (14); the resistance mechanism (14) is arranged between the tower head (4) and the tower body (3); the resistance mechanism (14) is composed of an upper disc (7), a lower disc (8) and a rotating shaft (9); two arc-shaped holes (11) are arranged on the upper disc (7), and upper disc fixing columns (10) are respectively arranged on the upper surface of the upper disc (7) at both ends of the arc-shaped holes (11); two lower disc fixing columns (12) are arranged on the lower disc (8), and the two lower disc fixing columns (12) are respectively arranged in the arc-shaped holes (11); and a resistance connecting piece (13) is arranged between the lower disc fixing column (12) and the two upper disc fixing columns (10).

[0006] The principles and beneficial effects of the present invention are:

[0007] In the resistance-type transmission line wind-proof iron tower of the present invention, a resistance mechanism (14) is provided between a tower head (4) and a tower body (3); an upper disc (7) in the resistance mechanism (14) is fixedly connected to the tower head (4), and a lower disc (8) is fixedly connected to the tower body (3); therefore, the tower head (4) and the tower body (3) can rotate relative to each other; and a resistance connecting member (13) provided in the resistance mechanism (14) is a spring or a hydraulic connecting rod. The symmetrical arrangement of the resistance connecting members (13) can restore the relative rotation to the original position. When wind deviation occurs, the transmission line swings, causing the tower head (4) and the tower body (3) to rotate relative to each other. The resistance connecting member (13) can offset the torque of the relative rotation, further stopping the swing and causing the tower head (4) to return to its initial position under the restoring force of the resistance connecting member (13). The tower head (4) and the tower body (3) can rotate relative to each other, reducing the pulling force of the wind deviation on the transmission line, avoiding the simultaneous resonance of the iron tower and the transmission line when the transmission line is wind deflected, effectively reducing the wind deviation energy, and further ensuring the safety of power supply.
