Embodiment 1

[0026] Embodiment one, see Figure 1~4 As shown, a linear pole tower overhead line sag measurement device includes an image acquisition module, a wireless transmission module, and a handheld control terminal. The handheld control terminal includes a wireless transceiver module. The terminal phase signal connection, the image acquisition module is set on the straight pole tower that needs to measure the sag of the overhead line, the image acquisition module includes an adjustable zoom lens module, a measurement scale module, a turntable unit, a sensor module, a power supply module, and an analog-to-digital conversion module , a motor drive module, a voltage stabilizing module and a control module, an adjustable zoom lens module, and a measurement ruler module are respectively arranged on two adjacent linear pole towers, and the adjustable zoom lens module is fixed on the linear pole towers through a turntable unit, wireless transmission The module is connected to the adjustable...

Embodiment 2

[0027] Embodiment 2 is basically the same as Embodiment 1, the difference is that the turntable unit includes a support plate, a fixed plate and a rotating plate, support legs are arranged on the support plate, the support legs are hinged and fixed to the linear tower, and the fixed plate includes a fixed plate. Ring, central rotating disc, ball group, a ball groove is arranged between the fixed ring and the central rotating disc, the balls are arranged in the ball groove, the fixed ring is fixed by the fastener and the supporting disc, and the central rotating disc and the rotating disc pass through the shaft It is hinged and fixed, and the rotating shaft is connected with a driving motor, and the driving motor is connected with the control module, so that the measurement is more convenient and reliable.

Embodiment 3

[0028]Embodiment 3 is basically the same as Embodiment 1, except that the handheld control terminal also includes a display module connected to the wireless transceiver module and a remote control terminal with a remote control operation interface. The module, the wireless transmission module and the control module are connected by signal. The remote control terminal remotely controls the turntable unit, the U-shaped rotating bracket and the adjustable zoom lens through the control module, and completes the focusing of the adjustable zoom lens and the pitch angle of the lens angle through the remote control terminal. The adjustment of the adjustment and the adjustment of the horizontal rotation angle of the lens through the turntable can timely and effectively measure the sag condition of the tension section of the overhead line of the power network, overcome many shortcomings in the existing measurement equipment, and use wireless transmission technology to enable the The oper...

Abstract

The invention relates to an intermediate support overhead line sag measurement device comprising an image acquisition module, a wireless transmission module, and a hand-held control end. The image acquisition module comprises an adjustable zoom lens module, a measuring scale module, a turntable unit, a sensor module, a power module, an analog-to-digital conversion module, a motor drive module, a voltage regulator module, and a control module. The control module is connected with a 360-degree steering engine module. The adjustable zoom lens module is fixed to the 360-degree steering engine module through a U-shaped rotary bracket. The U-shaped rotary bracket is rotationally connected with the control module through the motor drive module. According to the invention, remote control is carried out through the control module and the handheld control end, observation and measurement are convenient, and the sag of a strain section needing measurement can be measured by a single person. The human cost is reduced, and operation is easy. The efficiency and precision of overhead line sag measurement can be improved effectively, and the installation efficiency and measurement precision of the sag measurement device are improved.

Description

technical field [0001] The invention relates to the technical field of electric power operation measurement, in particular to a sag measurement device for a straight pole tower overhead line suitable for sag measurement in a power transmission line. Background technique [0002] The overhead line erected on the straight tower should have the stress according to the design, which is controlled by the sag of the overhead line. Sag refers to the vertical distance from any point on the suspension curve of the wire to the two suspension lines. The vertical distance to the lowest point of the wire is called the maximum sag. The sag we usually refer to refers to the maximum sag. If the sag is too small during construction work, the overhead line must bear excessive tension, greatly reducing the safety of the overhead line during operation; It will threaten the normal and safe operation of overhead lines. Therefore, the sag should be correctly calculated and observed during constr...
