Building ultrasonic measuring instrument for automatically acquiring data by using crank structure

Abstract

The invention relates to the technical field of ultrasonic measurement. The invention provides a building ultrasonic measuring instrument capable of automatically collecting data by utilizing a crankstructure. The instrument comprises a measuring instrument support and a sounding box, according to the building ultrasonic measuring instrument which automatically collects data through the crank structure, a fifth gear 9 rotates to drive a seventh gear to rotate; the seventh gear drives a sixth gear to rotate through gear engagement; the sixth gear drives a first connecting rod to rotate; the first connecting rod drives a rotating plate to do rotary closing motion; the sounding box approaches a measurement wall surface through a sliding groove; a surface grabbing rod abuts against the wall surface; the bottom of the surface grabbing rod is made of elastic cotton; the wall surface is extruded, the sounding box is kept in a horizontal measurement state, an ultrasonic sounder emits ultrasonic waves, the ultrasonic waves penetrate through the rotating plate, the ultrasonic waves are released in a centralized manner and are not easy to scatter in a propagation process so that the ultrasonic waves cannot be dispersed to influence surrounding personnel during measurement, the measurement effect of sound wave measurement is better, and repeated measurement at the same place is not needed.

Description

technical field [0001] The invention relates to the technical field of ultrasonic measurement, in particular to an ultrasonic measurement instrument for buildings that uses a crank structure to automatically collect data. Background technique [0002] Ultrasound refers to sound waves with a frequency higher than 20KHZ. It is widely used because of its small wavelength and high directionality of emission. Therefore, the ultrasonic propagation velocity can be accurately measured. It is mainly used to test indoor rock specimens. In terms of building measurement, the thickness and internal conditions of the wall are generally measured indoors by the staff holding the measuring instrument. If the measurement accuracy is high in high-rise buildings, the wall and wall External data collection requires high-altitude operations, which is more dangerous for workers. [0003] The commonly used ultrasonic measurement method for the wall needs to be manually operated, and the ultrasoni...

Problems solved by technology

[0003] The commonly used ultrasonic measurement method for the wall needs to be manually operated, and the ultrasonic wave used for a long time and at a high frequency is harmful to the human body. It can damage human cells and cause cancer. Uneven, in order to collect a variety of data, it is necessary for the staff to carry out high-altitude operations, which has a certain degree of danger, and because the ultrasonic waves are easy to diverge, it is difficult to receive accurate data, making the measurement efficiency low
