This application discloses a carrier device for an ultrasonic flow meter, used to connect a pipeline and an ultrasonic flow meter. The carrier device includes an integrally formed mounting part and a carrier part. The mounting part is fixedly connected to an opening in the pipe wall to install the carrier device on the pipeline, and the ultrasonic flow meter is installed through the carrier part.

The invention provides a test fixture for testing an image sensor chip, and aims to solve the problems of poor imaging consistency, limited site layout and the like caused by stray light generated by reflection and refraction of light on the surface of a structural member in an existing structure. The through straight hole is formed in the structure between the light source and the lens, and the transparent light guide piece is embedded in the straight hole, so that illumination light is transmitted in a unique and stable path. The material and the shape of the light guide piece can be freely selected according to requirements so as to adapt to different spectral characteristics and light source positions. The light enters the dodging part and the lens system after being directionally transmitted by the light guide part, and the middle does not contact the surface of a surrounding structure, so that stray light is effectively prevented from being generated, and the illumination uniformity and imaging consistency of each test position are remarkably improved. Due to the fact that the light path is strictly limited, the scheme is not limited by the field angle of the lens any more, the site distance can be reduced, a plurality of test positions can be flexibly arranged, the number of testable points in unit area is increased, and therefore the test efficiency and the throughput capacity of a production line are improved.

After fracturing, the changes in the amplitude parameters of the waveform information are measured again by rotating the device by a certain angle each time. The location of the fracturing can be determined based on the received waveform signals at different angles, and the presence or absence of rock mass fracturing can be determined by the changes in the waveform signal amplitude.
