Description

Technical Field

[0002] Depth measuring instruments generally use ultrasonic level meters to measure liquid levels. In some deep wells, due to the presence of liquid levels, the depth of the deep well can also be indirectly measured by using ultrasonic level meters installed on the deep well. The disadvantage of existing depth measuring instruments in actual use is that, since ultrasonic level meters are a relatively mature existing technology, they need to be used with corresponding brackets or directly installed on some structural parts during actual installation and use. However, when measuring multiple boreholes or deep wells, it is necessary to transfer the ultrasonic level meter to different locations for measurement. However, the installation and disassembly of existing ultrasonic level meters are relatively cumbersome and very inconvenient. People have conducted a lot of research on this. Utility Model Content

The utility model is a depth measuring instrument, including an ultrasonic level meter 11. The ultrasonic level meter 11 is a prior art. Electrical components are arranged inside it and can measure the depth by ultrasonic waves. The outer surface is covered with a shell. The shell can be individually designed and installed according to actual conditions. The ultrasonic level meter 11 is installed in the mounting plate 12 during actual use. The transmitting end of the ultrasonic level meter 11 faces downward. The mounting plate 12 generally needs to be installed above the deep well or borehole to be measured. The installation method can be installed using a more common bracket or other method.

[0022] Advantageously, a sleeve assembly for inserting and clamping the ultrasonic level meter 11 is provided in the mounting plate 12 , and a clamping assembly for conveniently clamping the sleeve assembly is provided on the ultrasonic level meter 11 .
