Ultrasonic probe stabilizing device and method used for water depth tester

Abstract

The invention discloses an ultrasonic probe stabilizing device used for a water depth tester, comprising an ultrasonic probe body, a speed measurement propeller, a sealed chamber and an empennage, wherein the speed measurement propeller is arranged at the front end of the sealed chamber, and the ultrasonic probe body, a rotary encoder, a driving motor and a control box are arranged in the sealed chamber; a controller is arranged in the control box; a rotating shaft of the driving motor penetrates through the sealed chamber and then is connected with a rotating sleeve in a driving manner; and adriving propeller is fixed on the outer wall, far away from the sealed chamber, of the rotating sleeve. The invention also provides an ultrasonic probe stabilizing method used for a water depth tester, comprising the following steps: the speed measurement propeller rotates, the rotary encoder converts rotating information of the speed measurement propeller into a Z phase signal which is sent to the controller; the controller processes the Z phase signal to obtain the flow velocity of water and the acting force of water flow; on and off of mercury switches SK1 and SK2 are judged; the driving motor is operated, and the operating speed of the driving motor is adjusted. According to the device and the method disclosed by the invention, the testing accuracy of the water depth tester for waterdepth can be improved.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to an ultrasonic probe stabilizing device and method for a water depth tester. Background technique [0002] The water depth wave sounder is a water depth measurement instrument suitable for rivers and lakes, reservoir channels, ports, coastal and deep sea underwater sections and underwater terrain surveys, navigation, underwater geophysical prospecting and many other water areas. The water depth sounder is designed according to the principle that its own ultrasonic probe emits ultrasonic waves. Ultrasonic waves can propagate in a straight line at a uniform speed in a homogeneous medium, and are designed according to the principle of reflection when encountering different medium surfaces; when measuring depth, place the ultrasonic transducer underwater for a certain time The position, the depth from the transducer to the bottom of the water can be calculated according to the prop...

AI Technical Summary

Problems solved by technology

For the ultrasonic probe for measuring still water depth, the position of the probe is fixed, but when measuring the flowing water depth, the position of the ultrasonic probe will have different position offsets with the flow velocity of the water, and the signal line of the ultrasonic probe is fixed. In the case of , the detected value will be biased
