Description

Technical Field

[0001] The invention patent relates to the technical field of detection devices, specifically a wire tension detection device for transmission lines and a method of using the same. Background Art

[0002] The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines.

[0003] Overhead transmission lines are composed of line towers, conductors, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. According to the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. DC transmission was first successfully realized in the 1880s. However, since the voltage of DC transmission was difficult to continue to increase under the technical conditions at the time, the transmission capacity and benefits were limited. At the end of the 19th century, DC transmission was gradually replaced by AC transmission. The success of AC transmission ushered in a new era of electrified society in the 20th century.

[0004] Transmission lines are facilities used to transmit electric energy in power systems. They connect the power generation site and the power consumption site, and are responsible for efficiently transmitting electric energy from power stations to substations or end users. The design and application of transmission lines need to consider a variety of factors to ensure the efficiency and safety of electric energy during transmission. Wire tension detection of transmission lines is crucial to ensure the safe and stable operation of transmission lines. The magnitude of wire tension directly affects the mechanical properties and structural safety of transmission towers. If the tension exceeds the design range, it may cause damage, tilting or even collapse of the tower. Such structural failure will not only interrupt the power supply, but may also cause serious safety accidents.

[0005] Since transmission lines are erected on higher towers, inspectors need to use special climbing equipment and other means to reach the corresponding height, which not only increases the complexity of inspection, but also increases costs and safety risks. Summary of the invention

[0112] Step 8, the connecting rod 6 drives the movable wheel 5 to squeeze the wire;

[0113] Step 9: Detect the tension by using the first detection probe, the second detection probe 25 and the detector 8.

[0114] Working principle:

[0115] like Figure 1 As shown:

[0116] Move the device to the working area, adjust the insulated telescopic rod 10 according to the height of the wire, and lift the top shell 1 close to the wire through the insulated telescopic rod 10.

[0117] Use the display control screen 13 and the camera 16 to observe the position of the top shell 1, and clamp the two fixing wheels 4 on the outside of the upper end of the wire.

[0118] like Figure 2 As shown:

[0119] The display control screen 13 is used to control the start of the driving motor 18, and the driving screw 19 rotates. The driving plate 20 and the driving screw 19 are threadedly matched and the sliding connection between the slider 22 and the slide groove 23 converts the rotational motion of the driving screw 19 into the linear motion of the driving plate 20, so that the driving plate 20 drives the pulley 21 to move and push the push rod 7.

[0122] like Figure 4 As shown:

[0123] When the first detection probe moves up to the limit position along the first placement groove, the first detection probe is squeezed, and the detector 8 converts the pressure on the first detection probe into a numerical value. When the second detection probe 25 moves up to the limit position along the second placement groove 24, the second detection probe 25 is squeezed, and the detector 8 converts the pressure on the second detection probe 25 into a numerical value.

[0124] The detector 8 transmits the numerical value to the display control screen 13 , and the inspector can check the tension of the wire by means of the display control screen 13 .

[0125] The beneficial effect of the present invention is that, compared with the prior art,

[0126] The patent of the present invention adds an insulating telescopic rod to the tension detection equipment, cooperates with the driving screw to drive the driving plate and the pulley at one end to move the push rod so that the movable wheel squeezes the wire, thereby performing tension detection on the wires of the high-altitude power transmission line.
