Description

Technical Field

[0001] The invention relates to the technical field of pressure pipeline monitoring, and in particular to a monitoring device for a civil construction pressure pipeline of a hydropower plant. Background Art

[0002] The monitoring of civil engineering pressure pipelines in hydropower plants is to ensure the safe operation of the civil engineering structures and pressure pipelines in hydropower plants. As an important energy production facility, the safety of its civil engineering structures and pressure pipelines is directly related to the stable operation of the facilities and the safety of life and property of personnel. Therefore, it is of great significance to monitor the civil engineering pressure pipelines in hydropower plants. The civil engineering pressure pipelines in hydropower plants undertake the important tasks of conveying water flow and bearing water pressure. Once they rupture or leak, they will have a serious impact on the surrounding environment and facilities. Therefore, monitoring the civil engineering structures and pressure pipelines is an important measure to ensure the safe operation of hydropower plants. At the same time, timely discovery and repair of problems in civil engineering structures and pressure pipelines can reduce maintenance costs, extend equipment life, and improve production efficiency, thereby bringing economic benefits. With the advancement of science and technology, monitoring technology is constantly updated and improved, which can more accurately monitor the status of civil engineering pressure pipelines and provide reliable guarantees for the safe operation of hydropower plants.

[0003] After searching, the invention with Chinese patent publication number CN213686252U discloses a pressure data monitoring device for pressure pipelines, which relates to the field of pressure pipeline monitoring technology. It includes a first air pressure sensor, a second air pressure sensor and a monitoring box. The first air pressure sensor and the second air pressure sensor are both fixed on the pressure pipeline body. A mounting pipe is fixed on the pressure pipeline body. A pressure gauge is fixed on the upper end of the mounting pipe. A pressure relief pipe is fixed on the lower end of the pressure pipeline body. Electric valves are fixed on both pressure relief pipes. An audible and visual alarm is fixed on the upper end of the monitoring box. A wireless transceiver module and a controller are placed in sequence from top to bottom inside the monitoring box. The air pressure at two locations can be detected by the first air pressure sensor and the second air pressure sensor, and the air pressure can also be detected by the pressure gauge to improve accuracy. The pressure data monitoring device for pressure pipelines in the above invention has the following shortcomings:

[0004] Although the support rod of the above device is fixedly connected to the pressure pipe body by bolts, and the support rod is connected to the block fixed on the upper end of the pressure pipe body by a slot, the cooperation of the slot and the block facilitates the quick installation of the monitoring box, saving time and effort.
