Description

Water depth measuring device with underwater protection function Technical Field The utility model relates to the technical field of underwater measurement, in particular to a water depth measuring device with an underwater protection function. Background In various fields such as mapping field and bridge construction field, it is necessary to measure the water depth of a river channel and the topography data of a river bed. In order to achieve water depth measurements as well as measurements of the topography of the river bed, it is often necessary to extend an ultrasonic probe under water. After the ultrasonic probe stretches into the water, the probe and the bracket for installing the probe are impacted by water flow, and for environments with higher water flow speeds, the impact of the water flow can damage the precise probe directly or twist the bracket for installing the probe, so that the underwater measurement of the ultrasonic probe is affected. Disclosure of utility model The utility model provides a water depth measuring device with an underwater protection function, which is used for reducing the impact of water flow on a probe and a mounting bracket during measurement and better protecting the probe. The utility model provides a water depth measuring device with an underwater protection function, which comprises: The main body is used for being placed on a measuring platform above a river bed; A first connecting piece connected with the main body, the lower end of the first connecting piece stretches into the water and is connected with a first probe, and The second connecting piece, the second connecting piece with the main part links to each other, the second connecting piece with first connecting piece is spaced, the lower extreme of second connecting piece stretches into under water and is connected with the vortex piece, the vortex piece is located the inflow side of first probe, the vortex piece is used for interfering the rivers that flow to first probe to reduce the impact of rivers to first connecting piece and first probe.
