Description

Technical Field

[0001] The invention relates to the field of marine detection, and in particular to a water depth detection mechanism. Background Art

[0002] At present, water depth measurement is to determine the plane position of each point on the bottom of the water and its depth below the water surface. It is a basic means of measuring seaways and seabed topography. Sounding instruments usually use sounding rods, water sluices, echo sounders, multi-beam echo sounder systems and seabed topography detectors. The measured instantaneous depth below the water surface can be converted to the depth calculated from the depth reference plane after correction by the depth sounder and the water level. The echo sounder uses the reflection of sound on the seabed to measure the depth of the ocean, just like the echo we hear in the valley. When detecting the depth of the seabed in a certain sea area, you must first use an echo sounder to send ultrasonic waves to the seabed. This ultrasonic wave is inaudible to human ears. After the ultrasonic wave is sent out, it will be reflected back when it reaches the seabed. After the echo sounder receives the signal, it calculates the time taken from the emission to the reception of the ultrasonic wave. According to the speed of the ultrasonic wave in the seawater of 1500 meters per second, the depth of the seabed can be known.

[0003] However, the existing water depth test has the following defects:
