An Ultrasonic Range Finder for Ocean Depth Measurement

Abstract

The invention relates to the technical field of ultrasonic distance measurement, and discloses an ultrasonic rangefinder for ocean depth measurement, comprising a caisson, the inside of the caisson is provided with a slide bar, and the surface of the slide bar is slidably connected with gravity The side of the gravity block is provided with a pressure-sensitive switch, the side of the gravity block is rotated and connected with a screw, the upper part of the meshing wheel is provided with a tapered shaft, and the opposite sides of the two tapered shafts rotate A fan is connected, the bottom of the water baffle is slidably connected with a magnetic tooth plate, the bottom of the magnetic tooth plate is engaged with a cam, the inner wheel surface of the cam is slidably connected with a push rod, and the side of the push rod slides An extruding tooth bar is connected, and the side of the extruding tooth bar is meshed with a water wheel. The ultrasonic range finder used for ocean depth measurement achieves the effect of preventing the ultrasonic transmitter from moving away from the original position when the undercurrent appears through the cooperation of the sliding bar and the gravity block.

Description

technical field [0001] The invention relates to the technical field of ultrasonic ranging, in particular to an ultrasonic ranging instrument for ocean depth measurement. Background technique [0002] Measuring distance through ultrasonic waves has strong directivity, slow energy consumption, and a long distance in the medium, so ultrasonic waves are often used for distance measurement, such as range finders and level range finders, etc. can be realized by ultrasonic waves. The use of ultrasonic detection is often relatively fast, convenient, simple to calculate, easy to achieve real-time control, and can meet the requirements of industrial practicality in terms of measurement accuracy, so it has also been widely used in the development of mobile robots. [0003] When measuring the depth of the ocean by ultrasonic waves, since the propagation of ultrasonic waves will be consumed with the increase of distance, in order to reduce the measurement error, it is necessary to put th...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an ultrasonic range finder for ocean depth measurement, which has the advantages of preventing the ultrasonic transmitter from moving away from its original position when an undercurrent appears, and solves the problem that the existing ultrasonic range finder cannot When the dark current appears, prevent the ultrasonic transmitter from moving away from the original position, making it difficult for the reflected super wave to be received, affecting the measurement of the distance
