Abstract:
1. A telescopic probe monitoring system for riverbed elevation monitoring at bridge piers comprising: a measurement module arranged at a bridge pier under the water for measuring elevation of a riverbed under water; the measurement module having a housing, a multi-layer tube mounted in the housing, a driving member that is attached with a plurality of scales, mounted in the housing and used for pushing the multi-layer tube to extend and contact the riverbed; a photographic unit mounted in the housing for taking pictures of the driving member and producing images; and a sensing unit disposed on bottom of the multi-layer tube; a control module coupled to the driving member and the photographic unit; the measurement module and the control module separated with each other; wherein the control module controls the driving member to push the multi-layer tube for extension of the multi-layer tube; while the sensing unit on bottom of the multi-layer tube contacts the riverbed under the water, the sensing unit sends a sensing signal to the control module for control of the driving member to stop pushing the multi-layer tube; the photographic unit shoots the driving member to generate the image; the control module gets the elevation of the riverbed according to the image and sends the elevation to a remote monitor unit.
