Installation structure of injection pressure type water level gauge

摘要

PROBLEM TO BE SOLVED: To provide an installation structure for an immersion pressure type water gauge which can be fixed in a place where water flow is rapid, and is easy to pull up and re-install and allows the work time for inspection or the like to be reduced.SOLUTION: An installation structure 10 for an immersion pressure type water gauge used to detect a water level in a treatment tank of a sewage treatment plant comprises: a guide rail 18 which is fixed to an inner wall surface 16 of a treatment tank 12 and is stood in the treatment tank 12 in the sewage treatment plant; a protection pipe 22 being a protector which is attached to the guide rail 18 and has an immersion pressure type water gauge 14 inserted thereinto to protect it in the vicinity of a bottom 20 of the treatment tank 12 and has both ends opened; and a guide chain 26 which is fixed to the protection pipe 22 and is appended to a water gauge cable 24 for transmitting a signal detected by the immersion pressure type water gauge 14 to the outside of the treatment tank 12. The protection pipe 22 has an attachment member 28 provided on an outer peripheral surface thereof, and the protection pipe 22 can be slid in a vertical direction with respect to the guide rail 18 by the attachment member 28.SELECTED DRAWING: Figure 1
