Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the present invention includes a long rod 1 and a data collector 2, the long rod 1 adopts a solid structure or a hollow structure, and the lower end of the long rod 1 is set as a pointed shape 3, so as to facilitate construction and drive into the measured sea bed or river bed. Two earth pressure measurement units 4 and one osmotic pressure measurement unit 5 are also arranged at intervals on the side wall of the long pole 1. After the output ends of the two earth pressure measurement units 4 and osmotic pressure measurement unit 5 are connected in parallel via a cable 6, they are connected to the data The input end of the collector 2, and then realize the measurement of the scour depth of the measured seabed or riverbed.

[0017] In the above embodiment, the two earth pressure measurement units 4 and the osmotic pr...

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...
