Description

TECHNICAL FIELD

[0001] The utility model relates to nuclear power plant operation and maintenance field especially underwater foreign matter multifunctional salvage device. BACKGROUND

[0002] During the operation of the nuclear power plant, foreign matters such as damaged equipment components, solid or dust blown by the unclean ventilation system, shed equipment structural parts, pipeline equipment surface corrosion products and oxide layers, impurity sediments generated during maintenance, and foreign falling impurities generated during inspection and production may be produced in the reactor pool, component pool, spent fuel pool, and waste water collection pit, etc. These foreign matters must be cleaned during routine and overhaul periods, otherwise water quality may be degraded, and the primary loop equipment, reactor components, and pool, pit transmission facility pipelines and pump sets may be damaged, and even the primary loop pressure boundary and equipment may be destroyed. The existing underwater foreign matter salvage is generally performed by mechanical hand grabbing, and the loose impurities at the bottom of the water are filtered by pumping, and the surface floating impurities are salvaged by net. The mechanical grabbing method is used to grab the large volume static foreign matters under the water, and the disadvantages are that the volume of the foreign matter and the grabbing device are not matched, and it is difficult to grab the foreign matters of different volumes due to the complex and narrow underwater environment of the reactor pool, component pool, and spent fuel pool. For the impurities at the bottom of the water, such as the sediments, metal oxides, and condensates at the bottom of the waste water collection pit, the grabbing may cause damage, and the condensate sediments and oxides are difficult to be sucked by the pumping device, and the cross use of various devices makes the efficiency low. Moreover, the foreign matters may be displaced during the salvage process, and the direction of the foreign matters cannot be tracked in real time to ensure that the foreign matters are completely taken out.

[0003] The existing underwater foreign matter suction device improves the salvage and suction efficiency of the foreign matters, can save cost, and increase efficiency, but does not have the multifunctional salvage function of different volumes of foreign matters in different forms, cannot break, disperse, collect, and process the large volume condensates, sediments, and oxides under the water, causes certain difficulty in the suction process, reduces the foreign matter salvage work efficiency, and may cause the foreign matters to be accidentally displaced and lost during the salvage process.
