Specific embodiment
As shown in Figure 1,2,3, 4, it is a kind of to receive stress-strain optical fiber test apparatus for external floating roof tank floating plate column, including outer
Floating top oil tank 1, interior floating plate 2, column 3, Fibre Optical Sensor 4, optical fiber 5, in the external floating roof tank, upper end is provided with connecting rod 6, even
Floating plate 2 in the connection of 6 one end of extension bar, interior floating plate 2 are symmetrically arranged on two with column 3, are provided with some Fibre Optical Sensors 4, optical fiber in column 3
Sensor 4 is connected with each other by optical fiber 5, and 1 outer ledge of the external floating roof tank is provided with some protective covers 7, placement in protective cover 7
There is Fibre Optical Sensor 4,3 upper end of the column is provided with aperture, and the optical fiber 5 on Fibre Optical Sensor 4 is connected by aperture, optical fiber 5 one
Towards control room, the interior floating plate 2 is provided with some arc grooves at end, interior floating plate 2 be provided with it is some be spaced reinforcement, it is described
Until tank bottoms, top is connected to tank deck to 3 bottom of column, and column side is fixed in external floating roof tank, and 3 opposite side of column is floating with interior
Arc groove connection on disk 2,3 surface of the column are provided with corrosion-resistant finishes, and the corrosion-resistant finishes is by following component and weight
Part composition：5 parts～10 parts of HfC, ZrB255 parts～70 parts, Sc2O310 parts～15 parts of 8 parts～10 parts SiC, TiB27 parts～
10 parts, 0.001 part～0.002 part of ammonium heptamolybdate, 1 ~ 3 part of methylglyoxal, 6 points of the connecting rod are that some sections of centres pass through removable pin
Axle is connected.Ammonium heptamolybdate and methylglyoxal can couple the reliable antiseptic property of generation with coated substance, and safety also has very big
Improve.During real work, two root posts 3 are symmetrically housed in external floating roof tank 1, uprights vertical is in 1 bottom of external floating roof tank, bottom
Until tank bottoms, top is connected to tank deck, and two on interior floating plate 2 arc groove is contacted respectively at two root posts 3, is interior floating plate 2
Play a part of guiding, interior floating plate 2 can fluctuate with the height change of oil loading height, during 6 points of connecting rod is some sections
