Ultrasonic range finder for ocean depth measurement

Abstract

The invention relates to the technical field of ultrasonic ranging. The invention further discloses an ultrasonic range finder for ocean depth measurement. The ultrasonic range finder comprises a caisson; a sliding rod is arranged in the caisson; the surface of the sliding rod is slidably connected with a gravity block; a pressure-sensitive switch is arranged on the side surface of the gravity block; the side surface of the gravity block is rotationally connected with a screw rod; conical shafts are arranged above a meshing wheel; fans are rotationally connected with the opposite sides of thetwo conical shafts; a magnetic toothed plate is slidably connected with the bottom of a water baffle; a cam is connected with the bottom of the magnetic toothed plate in a meshed mode; an ejector rodis slidably connected with the surface of an inner wheel of the cam; an extrusion toothed rod is slidably connected to the side face of the ejector rod; and a water passing wheel is connected with theside face of the extrusion toothed rod in a meshed mode. According to the ultrasonic range finder for ocean depth measurement, through cooperative use of the sliding rod and the gravity block, the effect of preventing an ultrasonic transmitter from moving away from the original position when undercurrent occurs is achieved.

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
