Electronic bathymeter

Abstract

The invention relates to an electronic bathymeter, which is characterized by comprising a pole and a data collector, wherein the lower end of the pole is shaped like a sharp angle; two soil pressure measurement units and an infiltration pressure measurement unit are arranged on the side wall of the pole at intervals; after being connected in parallel by a cable, the output ends of the two soil pressure measurement units and the infiltration pressure measurement unit are connected to the input end of the data collector; and the data collector is used for measuring the pressure acting on each pressure measurement unit, thus not only realizing real-time monitoring of the scour depth and the maximum scour depth of the measured seabed and riverbed, but also measuring the back siltation process. The electronic bathymeter can be extensively applied to measuring the scouring conditions of the riverbeds or seabeds around various building structures.

Description

technical field [0001] The invention relates to a surveying instrument, in particular to an electronic depth sounder for measuring scour conditions such as the scour depth of underwater seabeds or riverbeds around various buildings in oceans or rivers. Background technique [0002] At present, when monitoring the erosion of underwater soil layers around bridge piers, artificial islands, ports, docks, spurs, etc. in oceans or rivers, the commonly used sounding devices include sounding rods, sounding hammers, echo sounders, laser sounders, etc. Depth gauge or electromagnetic slip ring depth sounder, etc. Among them, manual sounding devices represented by sounding rods and sounding hammers have low measurement efficiency and are easily affected by many factors such as water depth, flow velocity, gravel and ice, and are inconvenient to use; echo sounders and The laser depth sounder has a high measurement accuracy, but when the water flow has a large sediment concentration or th...

Among them, manual sounding devices represented by sounding rods and sounding hammers have low measurement efficiency and are easily affected by many factors such as water depth, flow velocity, gravel and ice, and are inconvenient to use; echo sounders and The laser depth sounder has a high measurement accuracy, but when the water flow has a large sediment concentration or there are icicles and floating objects, its measurement accuracy will be significantly affected, and the echo sounder and the laser depth sounder are relatively expensive. Higher; while the electromagnetic slip ring depth sounder can only record the maximum value of erosion, and cannot measure the process of sediment back-silting
