INCLINATION MEASURING DEVICE OF WATER SEALED GAS HOLDER, AND INCLINATION MEASURING METHOD OF WATER SEALED GAS HOLDER

摘要

PROBLEM TO BE SOLVED: To provide an inclination measuring device of a water sealed gas holder capable of measuring inclination of a gas tank stably without depending on an external environment by using an inexpensive measuring device.;SOLUTION: This inclination measuring device 10 of the water sealed gas holder is equipped with a water tank, first to third base columns, and the gas tank 41 provided movably up and down. The inclination measuring device 10 includes first to third detection bodies connected at the same relative height to the gas tank 41; the first sensor 11A arranged at the first height of the first base column, for detecting passage of the first detection body; the second to fourth sensors 11B-11D arranged respectively on the second height of the first to third base columns, for detecting passage of the corresponding first to third detection bodies; and an inclination calculation means 13 for calculating inclination of the gas tank 41 based on a time difference of each detection timing between the first sensor 11A and the second sensor 11B, and on each detection timing by the second to fourth sensors 11B-11D, when the gas tank 41 is moved up or down.;COPYRIGHT: (C)2008,JPO&INPIT
