Title: Device for detecting shape of snow accretion on electric cable
Inventor: KAGAMI ATSUSHI
IPC: G01B11/24
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a device for detecting shape of snow accretion on electric cable which can detect the shape of snow accretion on an electric cable in real time and can be made compact in constitution. SOLUTION: A device for detecting shape of snow accretion on electric cables uses a sample electric cable having windows 8 for measurement as an electric cable 7 and, when the device is used, many reflection type red sensors are radially positioned in the cable 7 on the cross section of the cable 7 so that rays of light may be emitted to the outside from the windows 8. The red sensors are positioned in the same arrangement on a plurality of cross sections in the length direction of the cable 7 and the three-dimensional shape of snow 2 accretion on the cable 7 is detected by processing the output of each sensor by means of a signal processing section 9. Since no measuring section is housed in the cable 7, the device can be made compact in constitution and, in addition, the device can detect the three-dimensional shape of the snow 2 in real time without using any moving mechanism.
