An intelligent high-precision ultrasonic interface instrument

Abstract

An intelligent high-precision ultrasonic interface instrument, including a controller, an ultrasonic measuring probe A, an ultrasonic measuring probe B, a mounting block and at least one ultrasonic generator, the ultrasonic measuring probe A and the ultrasonic measuring probe B are fixed on the mounting block, the The ultrasonic measuring probe A is used to measure the thickness of the mud layer in the vertical direction. The ultrasonic generator is arranged on the surface of the installation block, and the ultrasonic generator is connected with the controller; There are two electric telescopic rods, and the two electric telescopic rods are connected to the controller. Half of the isolation cover is fixed on each of the two electric telescopic rods. The ultrasonic measuring probe B transmits and receives ultrasonic waves to the inner wall of one isolation cover, and Used to measure the horizontal mud layer concentration. The present invention adopts an integrated design, which can realize the cleaning of the measuring probe and the measurement of the mud layer concentration without frequently pulling up and lowering the probe, and without laying additional pipelines.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and in particular relates to an intelligent high-precision ultrasonic interface instrument. Background technique [0002] The measurement of the ultrasonic mud-water interface instrument is to use the ultrasonic sensor installed in the water to transmit a beam of ultrasonic pulses to the surface of the mud under the water. The pulse signal is reflected back after encountering the mud surface and can be received by the sensor again. The solid content of the slurry The larger the value, the greater the ultrasonic attenuation value, and the real-time ultrasonic attenuation is used to distinguish different layers in the liquid. [0003] The main reasons for the inaccurate measurement of the ultrasonic mud-water interface instrument in actual use are: 1. The dirt attached to the surface of the ultrasonic measuring probe affects the transmission and reception of ultrasonic waves; 2. Some...

Problems solved by technology

[0003] The main reasons for the inaccurate measurement of the ultrasonic mud-water interface instrument in actual use are: 1. The dirt attached to the surface of the ultrasonic measuring probe affects the transmission and reception of ultrasonic waves; 2. Some mud layers gradually transition from low concentration to high concentration, and the interface is not clear

[0004] For the first reason above, it is necessary to clean the ultrasonic measuring probe regularly. Many ultrasonic mud-water interface instruments on the market are equipped with a self-cleaning system, that is, the probe is regularly pulled up to rinse above the water surface. It is inconvenient and costly to install water pipes, sprinkler heads and other components; (2) Pulling up and down the probe frequently will pull the connecting cable and reduce the service life of the cable

[0005] For the second reason above, the compensation calculation is adopted at the software level. Although the error is getting smaller and smaller with the progress of the algorithm and the increase of the computing power of the processor, there is a certain error after all, and the high-precision instrument components are controlled by foreign countries. Restrictions, high purchase cost
