Background technique
Tension wire is generally located in the observation gallery of water conservancy project dam, is made of observation point, survey line and measuring box, by regular
Measurement observation point survey line measures the horizontal displacement of observation point to the distance between reference line.Current measuring box is generally by floating
Rest device and CCD tensile-line instrument are constituted, by alloing pontoon to survey line across pontoon in sink, and by tension wire pontoon
It is lifted, guarantee the height and position of survey line and survey line can be made freely to move horizontally, and drawn when survey line is moved horizontally by CCD
Bracing cable instrument can carry out dynamic measurement to the position of survey line, to obtain required deviant.
But since spring and autumn is moister, having moisture content and entering pontoon causes the liquid level in sink to increase, and is rising pontoon
The top of survey line collision CCD tensile-line instrument is caused after rising；And in summer then can because of temperature it is excessively high cause it is antifreeze in sink
Liquid evaporation, so that pontoon be made to cause the bottom of survey line collision CCD tensile-line instrument in lower backwardness, both of which, which will lead to draw, opens
Line wire body can not move freely, and cause the acquisition abnormity of data.Therefore, it is necessary to one kind to be monitored to the height of tension wire
And the device alarmed, so that the height and position of tension wire is maintained in the suitable measurement altitude range of CCD tensile-line instrument in real time.
