Embodiment Construction
[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0022] Such as figure 1 The cold source sea area detection and early warning system for nuclear power plants shown mainly includes a smart buoy detection component 1 , a data processing platform 2 and an early warning support component 3 .
[0023] Among them, the intelligent buoy detection component 1 includes a buoy frame body 11 and a buoy detection mechanism 10 installed on the buoy frame body 11. Its technical research and development first considers its technical indicators such as electricity, communication, and signal, and it has an open carrying capacity and can be compatible with The equipment involved, and can provide a reliable operating platform. The buoy frame body 11 is used to carry monitoring equipment, such as Figure 4 As shown, it includes a main floating body 111, a bracket body 115 fixed on the bottom of the main floating body 111, a ballast 11...

The invention relates to a detection and early warning system of a cold-source marine site of a nuclear power plant. The system comprises an intelligent buoy detection assembly, a data processing platform and an early warning support assembly; the intelligent buoy detection assembly comprises a buoy frame and a buoy detection mechanism mounted on the buoy frame, and the buoy detection mechanism comprises a buoy master-control unit, and a data collection processing unit, a GPS module, a wireless transmission module, a remote monitoring interface, a power management module and a buoy state monitoring module all connected to the buoy master-control unit; the data processing platform communicates with the intelligent buoy detection assembly; and the early-warning support assembly communicates with the data processing platform. Support is provided for improving the reliability of the cold source of the nuclear power plant comprehensively.
Description
technical field [0001] The invention belongs to the safety field of nuclear power plants, and relates to an early warning system, in particular to a cold source sea area detection and early warning system for nuclear power plants. Background technique [0002] In recent years, with the changes in the global environment, there have been more and more incidents of blockage of water intakes in nuclear power plants. From 2004 to 2008, 61 incidents occurred, most of which caused the power reduction of units, and some of them caused shutdowns. heap. Some events even directly affect the safety-related systems of nuclear power plants. In 2009, unit 4 of the French CRUAS nuclear power plant was invaded by a large number of aquatic plants. Weeds clogged the filter system of the pumping station, causing the No. 4 unit to lose its cooling source, and the operator reduced the power of the unit by 20%. According to the statistics of EDF Company, from the 1980s to the present, there hav...
