Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 , figure 2 , image 3 As shown, a deep-sea deployment method of sinkers for buoys, the deployment method includes preparation work, release work after the completion of the preparation work, measurement and positioning of the actual in-position point of the sinker after the release (so that it can be judged The actual placement point of the sinker is consistent with the scheduled placement point, and whether to make corrections is determined according to the specific distance difference); the preparation includes the following steps: ① Determine the scheduled placement of the sinker in the sea area of ​​the water intake of the nuclear power plant ② Conduct a thorough survey of sea temperature, salinity, currents, and conditions in the area where the scheduled location is located; ③ Calculate the horizontal d...

Abstract

The invention relates to a deep-sea laying method for a sinker used for a buoy. The laying method comprises preparation work and placing work after the preparation work is completed. The preparation work comprises the following steps: (1) determining a predetermined location of the sinker in a sea area of a water intake of a nuclear power plant; (2) thoroughly investigating temperature, salinity,sea currents and conditions of the sea area in the area of the predetermined location; (3) calculating a horizontal distance value between a sea surface placing point of the sinker and the seabed predetermined location of the sinker so as to determine the sea surface placing point of the sinker. The deep-sea laying method for the sinker used for the buoy is capable of determining the predeterminedlocation of the sinker by measuring on-site hydrological data, calculating a displacement value of the sinker after the sinker sinks into the water according to corresponding measurement parameters,and compensating and correcting the sea surface placing point of the sinker, thereby realizing the rapid and accurate placement of the sinker to the seabed predetermined location, supporting the accurate fixing of a buoy carrier, and reducing the occurrence of cold source security incidents at the water intake of the nuclear power plant.

Description

technical field [0001] The invention relates to the safety field of nuclear power plants, in particular to a method for laying sinkers in deep sea for buoys. Background technique [0002] In recent years, with the increasing number of cold source safety incidents at water intakes of nuclear power plants, a total of 61 incidents occurred between 2004 and 2008, most of which caused the power reduction of the unit, and some even caused the shutdown of the unit. Some events even have a direct impact on safety-related systems of nuclear power plants. Therefore, as the front-end part of detection and early warning, buoys and other facilities equipped with a large number of detection equipment are arranged in the extension section of the water intake; It is complicated, and the direction and velocity of the bottom water flow are not fixed, which has a great influence on the placement of sinkers; therefore, it is an urgent problem to be solved by those skilled in the art to find a ...
