Title:
PIPE MAPPING PROBE DEVICE FOR IDENTIFYING PIPE PATH POSITION
Document Type and Number:
WIPO Patent Application WO/2016/159434
Kind Code:
A1
Abstract:
A pipe mapping probe device for identifying a pipe path position, of the present invention, comprises a first pig having: a sensor unit, which has three acceleration sensors and three gyro-sensors, provided inside of an internal body unit of a first pig; a control board unit, which has a control unit, formed on one side of the sensor unit, the control unit controlling acceleration information, of a three-dimensional angular axis, generated from the three acceleration sensors to be generated and stored in a memory unit, angular speed information, of a three-dimensional angular axis, generated from the three gyro-sensors to be generated and stored in the memory unit, and moving distance information received from an encoder of a second pig to be received and stored in the memory unit; and an outer body unit, which has a battery unit, for supplying power to the acceleration sensors, the gyro-sensors, and the control board unit, provided on one side of the control board unit, and encompasses the internal body unit, and the pipe mapping probe device comprises: a cable connected so as to supply power from the battery unit to the acceleration sensors, the gyro-sensors, the control board unit, and the encoder, and to receive information generated from the acceleration sensors, the gyro-sensors, and the encoder; an elastic member having a plurality of springs for connecting the first pig and the second pig; and the second pig having a reel unit coupled to the elastic member and in which a steel wire is wound and unwound inside the internal body unit, and having the encoder for calculating a moving distance of the mapping probe device within a pipe on the basis of an unwound length of the steel wire in the reel unit and for transmitting the calculated result to a control board. The pipe mapping probe device of the present invention is configured such that: a steel wire is fixed to a launcher at the origin point of a pipe, and the pipe mapping probe device moves within the pipe when water pressure is applied to the pipe after the pipe mapping probe device is inserted into the pipe; and while moving, acceleration information of a three-dimensional angular axis, angular speed information of the three-dimensional angular axis, and moving distance information of the pipe mapping probe device are stored in the memory unit itself.
