Reel assembly for dewatering apparatus

Apparatus for removing water or other liquid from a bore or the like, said apparatus including a reel assembly, flexible discharge conduit means wound about said reel assembly, said conduit means being connected at its free end to submersible pump means, means for mounting said reel assembly for rotation so that said pump means and conduit means may be lowered into said bore hole or raised therefrom, and there being provided a roller assembly operatively engaged with said conduit means and adapted to guide said conduit means between said reel asembly and said bore hole, said roller assembly including a plurality of pairs of diametrically opposed rollers, the rollers of each said pair having a concave outer surface conforming substantially to the outer surface conforming substantially to the outer surface of said conduit means, the rollers in each said pair cooperating to substantially surround said conduit means so as to circumferentially support said conduit means, said pairs of rollers being arranged along an arc to deflect said conduit means from said reel assembly and align said conduit means with said said bore hole, drive means coupled to at least some of said rollers to cause rotation thereof in a direction to assist in unwinding said conduit means from said reel assembly, hydraulic motor means operatively coupled to said pump means to drive said pump means so that water or other liquid in said bore hole may be delivered by said pump means into said conduit means for passage therealong and discharge, and there being provided hydraulic fluid supply and exhaust pipes coupled to said hydraulic motor means, said pipes being arranged within said discharge conduit means and extending therealong so that hydraulic fluid in said supply and exhaust pipes is subject to the cooling effect of water or other liquid flowing through said conduit means.
