Safety monitoring method for heat supply pipeline

Abstract

The invention discloses a safety monitoring method for a heat supply pipeline. The method comprises the steps: enabling a temperature-sensing optical cable to sequentially pass through a first through groove and a second through groove of a protection plate, enabling the temperature-sensing optical cable to be wound on an outer sleeve in a spiral manner, enabling a connection plate on the outer sleeve to be correspondingly inserted into a connection groove of the protection plate until a fixing groove is aligned with an insertion groove, and enabling a bolt to be inserted into the fixing groove and the insertion groove to form threaded connection among the bolt, the fixing groove and the insertion groove. The temperature-sensing optical cable penetrates through the protection plate and is protected and fixed through the outer sleeve, the temperature-sensing optical cable can make full contact with the outer sleeve effectively, the temperature sensing optical cable is spirally wound around the outer sleeve, the contact area of the temperature sensing optical cable and the outer sleeve can be increased, and then the temperature of the surface of the outer sleeve can be monitored more comprehensively; therefore, the monitoring range is wider, the monitoring is more accurate, and the situation that the heat supply pipeline is broken and is not known due to the fact that monitoring is not in place due to the fact that the contact area of the temperature-sensing optical cable is too limited in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of heating pipeline safety monitoring, in particular to a heating pipeline safety monitoring method. Background technique [0002] In the prior art, a thermal pipeline is a pipeline for transporting thermal energy medium such as steam or superheated water. After years of urban transformation, thermal pipelines in large and medium-sized cities mostly adopt underground laying, including pipe trench laying and direct burial laying. Thermal pipelines will be subjected to high temperature, wear, physical and chemical effects during use, coupled with the disturbance of surrounding underground engineering construction and ground traffic dynamic loads, thermal pipelines will gradually produce defects such as cracks, deformation, and joint damage, and then evolve into fractures, Accidents such as water leakage. During the heating period, if a large amount of water leaks or even breaks in the pipeline, due to the hi...

Problems solved by technology

For the complex structure of pipeline laying process or the change of operating conditions when adjusting pumps and valves, abnormal image features may appear in the case of no leakage, resulting in false alarms, excessive positioning accuracy errors, resulting in difficult maintenance, and It is difficult to estimate the size of the leak and make a maintenance plan, so it can only be dealt with according to the actual situation after excavation, which greatly prolongs the maintenance time and increases the maintenance cost. Therefore, the present invention provides a heating pipeline safety monitoring method, which can accurately monitor the heating Real-time monitoring of pipeline safety
