Water depth detection mechanism

Abstract

The invention discloses a water depth detection mechanism. The mechanism comprises a signal transmitter, an upper mounting base, a waterproof sleeve, a lower mounting base, a connecting rod, an analogmatching board, a circuit board, an ultrasonic transmitter, a plurality of fixing screws and a plurality of waterproof sealing rings, the upper mounting base is provided with a plurality of upper mounting holes and a plurality of upper sealing grooves; the lower mounting base is provided with a plurality of lower mounting holes and a plurality of lower sealing grooves, the signal transmitter andthe ultrasonic transmitter are in communication with the circuit board, a fixed distance is formed between the simulation matching board and the lower mounting base, and the signal transmitter is in communication with a remote terminal. On one hand, the waterproof sleeve is a standard pipe fitting, the waterproof sleeve, the upper mounting base, the lower mounting base and the waterproof sealing ring are mounted in a matched mode, manufacturing is easy and convenient, efficiency is high, on the other hand, the sound velocity value of actual water quality is measured by simulating a matching plate to form a fixed distance, then deep testing is conducted, and testing accuracy is high.

Description

technical field [0001] The invention relates to the field of marine detection, in particular to a water depth detection mechanism. Background technique [0002] At present, bathymetry is to determine the plane position of each point on the bottom of the water and its depth below the water surface. It is the basic means of hydrographic survey and seabed topographic survey. Depth sounding system and seabed geomorphology detector, etc. The measured instantaneous depth under the water surface can be reduced to the depth calculated from the depth datum after being corrected by the depth sounder and the water level. The echo sounder uses the reflection of sound on the seabed to The ones that measure the depth of the ocean are like the echoes we hear in valleys. When detecting the depth of the seabed in a certain sea area, an echo sounder is first used to send ultrasonic waves to the seabed, which cannot be heard by human ears. After the ultrasonic wave is sent out, it will be re...
