Technical Field

The invention relates to the technical field of pipeline detection, in particular to an embedded water supply pipe network infrared flaw detection camera.

Background

The water supply pipe network is a pipeline system for delivering water and distributing water to users in water supply engineering and consists of pipelines, accessories and accessory facilities; common water supply pipe materials include cast iron pipes, steel pipes, and prestressed concrete pipes. With the rapid development of modern cities, the population number of the cities is rapidly increased, and the operation of water supply pipelines brings great pressure. At present, the demand asymmetry of water supply and water use in cities is severe, and water conservation becomes a point which must be considered in the environmental development of China. Therefore, municipal water supply network leakage and flaw detection are urgently needed.

Aiming at the existing detection of a water supply pipe network, a pipeline detection robot is mostly used for pipeline detection and flaw detection. But the pipeline robot is only suitable for running in pipelines with larger pipe diameters because of the limitation of the structure of the pipeline robot. The water supply pipe network is complicated, and the pipe diameters of the pipe sections are changed frequently, so that the pipeline detection robot is not suitable for detection of the water supply pipe network. In addition, the water supply pipe network is used for water delivery, and the internal environment is humid and is not suitable for electronic equipment to enter.

Embedding is the process of encapsulating a powder or other bulk structure of a material to be embedded with an embedding agent (which may be an organic plastic, metal, etc.) to provide performance support or chemical protection. If can utilize the embedding technique directly to get up the camera parcel and put in to the water supply pipe network and detect, will realize the optimization to municipal water supply pipe network effectively.
