Probe type monitoring system for bed height of bridge pier

Abstract

The invention relates to a probe type monitoring system for the bed height of a bridge pier. The probe type monitoring system comprises a shell, a measuring rod, a shifter, a control module, a photographing unit and a sensing unit, wherein the shell is fixed on the bridge pier; the shifter is arranged in the shell and drives the measuring rod to move; the control module is arranged in the shell for controlling the shifter to move the measuring rod; the sensing unit is arranged at the bottom of the measuring rod; when the control module controls the measuring rod to move, and the sensing unit is contacted with a bed under water, the sensing unit can transmit a sensing signal to the control module, so that the shifter is controlled to stop moving the measuring rod, and the photographing unit is controlled to photograph the measuring rod to generate an image; and the control module acquires the height of the bridge pier bed according to the image or the actuating state of the shifter, and transmits the height of the bridge pier bed to a remote monitor unit. Therefore, the height of the bed can be monitored in real time.

Description

technical field [0001] The invention relates to a monitoring system for the elevation of the pier bottom bed, in particular to a probe type monitoring system for the elevation of the pier bottom bed. Background technique [0002] In recent years, there have been frequent wind and flood disasters in countries all over the world. Whenever disasters come, rivers and streams often swell, causing serious erosion of bridge pier foundations, leaving the foundation piles of bridge piers exposed, which will lead to insufficient lateral bearing capacity of the bridge. As a result, tilting or breaking occurs. If the flood is too large, it will directly break the bridge piers, and then cause the bridge to suddenly fall directly into the water, endangering traffic safety. The above situation not only leads to the interruption of traffic communication, but also often causes the loss of people's lives, public property and local construction in a short period of time. Therefore, in order ...

Problems solved by technology

The disadvantage is that the optical fiber must be buried in the bed and directly attached to the water or sand surface, and the optical fiber is fragile and easily damaged

[0012] From the above description of the commonly used monitoring methods today, it can be known that there are certain limitations and inconveniences in their use. The general monitoring system is either to be excavated and buried in the bed, or it only has one-time measurement, and the excavation The process consumes manpower and cost, and will cause changes in the environment and thus affect the safety of the bridge pier
