Abstract

The invention relates to a stress detection flange which comprises a flange body and is characterized in that flange reserved grooves and a reserved wiring groove connected with the flange reserved groove are reserved in the surface of the flange body, a piezoresistive sensor is buried in each flange reserved groove, and a power supply and acquisition unit and a transmission module are mounted ina flange hole. The piezoresistive sensor is connected with the power supply and acquisition unit through a line arranged in the reserved wiring groove, and the power supply and acquisition unit is further connected with the transmission module. The piezoresistive sensors are buried in empty grooves reserved in advance in a flange, the power supply and acquisition unit detects stress data of the piezoresistive sensors in real time, and the data is collected and then transmitted to a unified cloud management platform through a transmission unit. The alarm value of the stress at the flange connection part is set through a cloud platform, so that the real-time state of a flange connection system can be remotely mastered for analysis and use of a management department.

Description

technical field [0001] The invention relates to the field of new infrastructure facilities, in particular to a force detection flange, which uses a piezoresistive sensor to detect force in real time, thereby judging the connection performance or airtight performance of the flange in real time. Background technique [0002] The flange connection system is commonly used in detachable and connected steel structure components. It is an important content in the fields of municipal, electric power, communication, and public pipelines. The stress of the flange is an indispensable link in the analysis of steel structures. Flange connection The failure of the system will lead to the loss of reliable connection or sealing ability of steel structural members. [0003] Therefore, timely understanding of the force process of the flange connection system, and real-time collection of relevant data on the force of the flange connection system through the communication network will enable th...
