Description

Technical Field

[0001] The utility model relates to the technical field of safety monitoring of power transmission towers, in particular to an installation and adjustment device for a power transmission tower toppling monitoring system. Background Art

[0002] Transmission towers are the supporting structures for high-voltage power lines and are a key component of overhead transmission lines. Like bridges for power transmission, they not only support conductors and insulators but also carry other electrical equipment, ensuring they maintain a safe distance from the ground and other structures. Therefore, the stability of transmission towers is directly related to the safety of transmission lines, which in turn impacts the stability and economic efficiency of the entire power grid system. Due to the variable geological and climatic conditions along overhead transmission line corridors, some towers are located in mined-out areas, on slopes, or in areas prone to erosion. These towers are frequently affected by factors such as directional winds, surrounding excavation activities, heavy ice coating on conductors, geological disasters, and human sabotage. These factors can lead to serious power outages such as tower tilt, collapse, or line breakage.

[0003] Traditional safety maintenance of transmission towers relies on regular inspections and manual observations. However, these methods are subjective, difficult to measure certain parameters, and may not identify problems in a timely manner, making it difficult to meet the real-time monitoring needs of the towers. In order to eliminate the safety hazards of transmission towers and prevent accidents such as tilting or collapse that may affect the safety of the power grid and the surrounding environment, it is necessary to adopt advanced toppling monitoring technologies and equipment to achieve continuous safety monitoring of transmission towers. Currently, there are many related technologies for tower toppling monitoring. For example, patent CN103487026A discloses a transmission line tower tilt monitoring system. The tilt angle information of the tower is collected by a tilt sensor, and the tilt angle information is transmitted to the host computer through a wireless transmission module and a line monitoring base station to monitor the tilt of the tower. Patent CN202956104U also discloses a transmission line tower tilt monitoring system. The tower tilt monitoring device includes a tilt sensor, a single-chip microcomputer, and a battery, etc., which realizes real-time online monitoring of the tilt of the transmission line tower.

[0004] At present, the real-time online monitoring technology for transmission tower toppling monitoring is relatively mature. However, when installing the toppling monitoring system, the toppling monitoring system is often fixed directly to the transmission tower with bolts. When manual work is carried out at high altitude, workers need to carry parts such as bolts and tightening tools, which is inconvenient to carry. In addition, parts are more likely to fall from high altitude during the installation process. Summary of the Invention

[0005] The utility model provides an installation and adjustment device for a transmission tower toppling monitoring system. The installation and adjustment device installs the toppling monitoring system on the transmission tower by means of an adjustment bracket and a fixed bracket clamped on the angle steel crossbeam of the transmission tower. During the high-altitude installation process, no other tools or parts need to be carried, the installation is convenient, the installation action is minimal, and the problem of tools or parts falling from a high altitude can be avoided.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings.

[0028] The tilting monitoring system 2 of the present invention is installed on the transmission tower 1 by installing an adjustment device, and performs real-time online monitoring of the tilting state of the transmission tower. Figure 1 and Figure 2 Specifically, the toppling monitoring system includes at least a battery-powered unit 21 and a monitoring unit 22 mounted on the transmission tower. The monitoring unit monitors the tower's tilt data. The battery-powered unit is connected to the monitoring unit to provide power. Specifically, the toppling monitoring system is mounted on a horizontally mounted angle steel beam 11 on the transmission tower.

[0029] In this embodiment, the installation and adjustment device includes an adjustment bracket 31, a fixing bracket 32 ​​and a clamping mechanism. Figure 3 and Figure 4 As shown. The overall L-shaped adjustment bracket includes a connected horizontal adjustment plate 311 and a vertical adjustment plate 312. The adjustment bracket is inverted and fastened to the outer corner of the angle steel beam. Specifically, the horizontal and vertical adjustment plates of the adjustment bracket are in contact with the two beam surfaces of the angle steel beam. In this embodiment, the tipping monitoring system is fixed to the horizontal adjustment plate. When the installation adjustment device is then installed on the transmission tower, the tipping monitoring system can be bolted to the horizontal adjustment plate beforehand, eliminating the need for high-altitude installation and avoiding the problem of carrying tools and parts falling.

[0030] The fixing bracket is also L-shaped as a whole, including a horizontal fixing plate 321 and a vertical fixing plate 322 connected to each other, and the fixing bracket is buckled on the inner corner of the angle steel beam; specifically, the fixing bracket is formed by bending an N-shaped plate, including a horizontal fixing plate and two vertical fixing plates in a C-shaped structure, as shown in FIG. Figure 3 .

[0031] The adjustable bracket and the fixed bracket are clamped to the angle steel crossbeam via a clamping mechanism, thereby securing the tilt monitoring system on the adjustable bracket. In this embodiment, two sets of clamping mechanisms are provided to ensure the clamping stability of the adjustable bracket and the fixed bracket. Each set of clamping mechanisms includes a first ratchet bar 33, a second ratchet bar 34, a horizontal compression spring 35, a vertical compression spring 36, a guide pin 37, and a clamping bolt 38. The first ratchet bar is abutted against the horizontal adjustment plate, with the ratchet teeth on the first ratchet bar facing the fixed adjustment plate. The second ratchet bar is connected to the horizontal fixed plate via a vertical compression spring and meshes with the first ratchet bar. The horizontal compression spring is connected between the second ratchet bar and the horizontal adjustment plate, thereby pressing the second ratchet bar against the first ratchet bar via the horizontal and vertical compression springs, thereby achieving horizontal press-fitting and clamping of the adjustable bracket and the fixed bracket. Specifically, a mounting block 4 is fixed to the horizontal adjustment plate, and the horizontal compression spring is connected between the second ratchet bar and the mounting block. It should be noted that after installation, both the horizontal compression spring and the vertical compression spring are in a compressed state, thereby ensuring that the first ratchet bar and the second ratchet bar are clamped.

[0032] The guide pin is fixedly connected to the vertical adjustment plate and faces the vertical fixing plate. The vertical fixing plate is provided with a guide hole, through which the guide pin extends and slides in position. The guide pin serves as an alignment mechanism, ensuring rapid alignment of the adjustment bracket and the fixing bracket, thereby ensuring rapid alignment of the first and second ratchet bars. During installation and tightening of the first and second ratchet bars, the fixing pin slides in position within the guide hole, assisting in the rapid tightening of the first and second ratchet bars.

[0033] The clamping bolt passes through the mounting hole provided on the horizontal fixing plate and is pressed against the angle steel beam, thereby compressing the fixing bracket in the vertical direction. Specifically, a tension spring 39 is sleeved on the clamping bolt, one end of the tension spring is fixedly connected to the clamping bolt, and the other end of the tension spring is fixedly connected to the bottom of the horizontal fixing plate. Since the tension spring is in a stretched state, the clamping bolt is always pulled upward to ensure that the clamping bolt is always pressed against the angle steel beam. Specifically, symmetrically arranged clamping blocks 310 are fixed along the axis of the mounting holes. The clamping bolt passes through the mounting hole and the clamping block and is clamped by the clamping block. Before installation, the clamping bolt can be clamped in a relatively lower position by rotating it and pulling it down. When the horizontal installation clamping is completed, the clamping bolt is rotated to press the angle steel beam upward.

[0034] In this embodiment, the tilt monitoring system is installed on the transmission tower by installing an adjustment device. The specific installation method is as follows: the tilt monitoring system is fixed to the adjustment bracket in advance, and the clamping mechanism on the adjustment bracket and the fixed bracket is installed in advance. At this time, the clamping bolt is pulled down and clamped at the bottom of the clamping block. During the high-altitude installation operation, no tools are required. The adjustment bracket is simply placed on the outer corner of the angle steel beam, and the horizontal adjustment plate and vertical adjustment plate of the adjustment bracket are both in contact with the two beam surfaces of the angle steel beam. Then, the fixed bracket is pushed under the inner corner of the angle steel beam. The positioning of the guide pin ensures that the first ratchet bar and the second ratchet bar are quickly aligned, and the first ratchet bar and the second ratchet bar are clamped under the compression rebound force of the horizontal compression spring and the vertical compression spring. Then, the clamping bolt is screwed up to tighten the angle steel beam, and the installation of the tilt monitoring system is completed.
