Description

Mounting device for pipeline joint deformation monitoring instrument Technical Field The utility model belongs to the technical field of water pipeline monitoring, and particularly relates to a mounting device for a pipeline joint deformation monitoring instrument. Background In long-distance water transfer engineering, a large-caliber water conveying pipeline plays a crucial role. Common water pipe types include cast iron pipes, steel pipes, glass reinforced plastic pipes, concrete pipes, prestressed steel cylinder concrete pipes, and the like. The pipelines are connected in various modes, including welding, socket joint, bonding, flange connection and the like. In these connection, welded, socket and adhesive-bonded pipe joints are critical parts of the overall pipe system. Due to pressure fluctuations, temperature changes, changes in geological conditions, and other factors, the pipe joint may deform, thereby causing leakage. The stability of the pipe joint is therefore decisive for the safe operation of the entire pipe system. In order to ensure the stability of the pipeline joint, the joint deformation is particularly critical to monitor. Permanent joint deformation monitoring is currently mainly achieved through sensors such as displacement meters or seam gauges, but pipes of different materials face many challenges in the sensor installation process. For example, cast iron pipes and steel pipes require removal of an external rust-proof coating and fixing of the sensor holder by welding, whereas glass steel pipes and concrete pipes usually use bonding after cleaning the surface to fix the sensor holder. The former breaks the integrity of the rust inhibitive coating and the latter places higher demands on the durability of the binding material. Through the above analysis, the problems and defects existing in the prior art are as follows: the traditional sensor base is installed on a cast iron or steel pipeline, an antirust coating is required to be destroyed, and the traditional sensor base is not firmly bonded on a glass reinforced plastic pipe and a concrete pipe and has poor durability. Disclosure of utility model Aiming at the problems existing in the prior art, the utility model provides a mounting device for a pipeline joint deformation monitoring instrument.
