Device for guiding water level measuring equipment in wells.

摘要

The invention refers to a device for guiding the measuring equipment for the water level in wells, designed for inserting and guiding the equipment for measuring the level of water in the working drillings, primarily for those in which the water level line is very deep. The device for guiding the measuring equipment of the water level in wells is mounted on a suction column (B), made of suction segments (C) and fitted at the lower end with a submersible pump (5), and the upper end rests against a breechblock (16). According to the invention, the device consists of a guide column (A) made of pipe segments (1) ending with inner threads (a), the first one at the lower end presenting apertures (b) along the entire surface. The pipe segments (1) are linked to each other by means of connecting nipples (2) and the fitting to the suction column (B) is performed by means of fixed semi-clips (9 and 10) and removable semi-clips (3), fastened by screws (4). The close placement to the above mentioned suction column (B) is due to the placement of column (A) inside circular millings (c and d) performed in the connection flanges (7 and 8) of the segments (C) and positioned on the same generators by means of props (11 and 12) to which the fixed semi-clips (9 and 10) are attached.
