Embodiment Construction

[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0031] Such as figure 1 As shown, the present invention provides a synchronous rotation mechanism of a dancing calibration device, which includes a turntable 1, a central gear 10, an instrument mounting bracket 9, a bracket end gear 8 and a gear transmission. The synchronous rotating mechanism is set vertically when in use, that is, the turntable 1 rotates in a vertical plane, and the turntable 1 is generally in the shape of a disc, and can also be in other forms. In this embodiment, it is in the shape of a disc. The center of rotation of the turntable 1 is fixed with a drive shaft 12, the drive shaft 12 is connected to the motor and driven by the motor to rotate at a certain speed and direction, the turntable 1 is driven by the ...

Abstract

The present invention provides a synchronous rotation mechanism of a galloping calibration device. The synchronous rotation mechanism comprises a rotary table, a central gear, an instrument installation support, a support end gear and a gear transmission device. A driving shaft is fixed at the center of the rotary table, the central gear is fixed on the pedestal, and the driving shaft is rotated relative to the central gear. The instrument installation support is arranged on the rotation table along a radial direction and is rotated relative to the rotary table; and the rotation shaft of the instrument installation support is arranged in parallel to the driving shaft. The support end gear and the rotation shaft of the instrument installation support are coaxially arranged and are synchronously rotated. The gear transmission device is engaged with the central gear and the support end gear to transmit rotation of the driving shaft to the instrument installation support to allow the instrument installation support to be the same as the driving shaft about a rotation speed and to be opposite to the driving shaft about a rotation direction. The synchronous rotation mechanism of a galloping calibration device can realize effective detection and calibration of data accuracy collected by a monitoring instrument through adoption of the galloping calibration device to ensure data outputsynchronization, accurately monitoring a galloping condition, timely publish early warning signals and effectively improve line operation safety.

Description

technical field [0001] The invention relates to the technical field of status monitoring of power transmission equipment, in particular to a synchronous rotation mechanism of a galloping calibration device. Background technique [0002] In recent years, the problem of climate change in our country has become increasingly prominent, and galloping accidents of high-voltage overhead transmission lines have occurred frequently, which has caused serious harm to the safe and reliable operation of the power grid. Galloping of transmission lines has the characteristics of complex mechanism, difficult treatment and strong destructive power, and has become an internationally recognized problem in the field of transmission lines. Monitoring the galloping of the transmission line can effectively complete the galloping early warning so that the staff can take timely countermeasures, reduce the economic loss caused by the galloping of the line, and provide valuable on-site data for the ac...
