A mounting structure of a hollowed-out ceramic brick curtain wall
This invention discloses an installation structure for a perforated terracotta brick curtain wall, relating to the field of terracotta brick curtain wall technology. Its key technical points are: Firstly, a T-shaped connector is used to engage with a T-shaped groove on the back of the terracotta brick, allowing the brick to be directly hung on the connector while also adjusting the spacing of the bricks. Secondly, a central cylinder and a connecting column are interlocked on the connector, with a locking pin on the central cylinder corresponding to a spiral groove on the outside of the connecting column. Therefore, when the connecting column is pressed, the locking pin, guided by the spiral groove, drives the connecting column to rotate. Based on this, a middle plate is placed on the connecting column. Thus, during terracotta brick installation, the brick can be hooked by flipping the middle plate. This effectively solves the technical problem of existing terracotta brick curtain walls being difficult to replace and easily affecting load-bearing capacity, thereby achieving rapid installation of terracotta bricks, eliminating the need for extensive installation time and reducing the time and difficulty of high-altitude operations.

The invention relates to the technical field of sewage treatment, and discloses a sewage biochemical treatment process abnormity intelligent early warning method and system based on image recognition, and the method comprises the steps: periodically collecting a sludge image and water quality sensing data; extracting floc form, bubble distribution and color texture features of the image, and performing space-time alignment fusion with the sensing data to construct a multi-source fusion feature matrix; inputting the matrix into a pre-trained digital twin evaluation model, calculating a dynamic deviation degree between a current state and a normal working condition, and identifying an abnormal mode; and generating a graded early warning signal according to the deviation degree and the abnormal mode and pushing the graded early warning signal. The system comprises an online image acquisition unit and a water quality sensor array which are used for data acquisition, and a feature processing module used for feature processing and fusion. According to the scheme, early-stage, accurate and intelligent early warning of abnormality in the sewage biochemical treatment process is realized, the false report and missing report rate is reduced, and the accuracy and the reliability of the system are improved. And the operation stability and the regulation and control efficiency of the system are improved.
