[0002] In-hole non-metallic water pumping pipe positioning and cutting is an engineering technology operation for the precise positioning and cutting of non-metallic pipes in underground boreholes. Its core objective is to achieve the positioning, fixing and clamping of pipes and non-destructive cutting in narrow and closed borehole environments using specialized equipment, so as to meet the engineering needs of fields such as geological exploration, groundwater monitoring, and abandoned well treatment.

[0003] The existing positioning and shearing devices for non-metallic water pumping pipes inside boreholes still have the following areas for improvement during use:

[0032] Working principle: The operator holds handle 3 and lowers the device into the borehole. Using the external laser rangefinder as needed, once the target depth is reached, cylinder 4 is activated to push the positioning component to unfold, causing connecting rod 1 7 and connecting rod 3 9 to swing. Then, through the symmetrical linkage of connecting rod 2 8 and connecting rod 4 10, adjusting rod 1 11 and adjusting rod 2 12 are driven to move. Fixed frame 1 13 and fixed frame 2 14 slide, realizing the radial unfolding or retraction of the positioning component to adapt to boreholes of different diameters. Rubber pad 17 presses against the inner wall of the water pump pipe to realize the adjustment of the diameter of the annular support. Holding handle 3 upward, the water pump pipe is lifted off the ground. As needed, an external cutter is used to facilitate the operator to cut the water pump pipe.
