Underground water pumping pipe assembly for underground water motor pump

Abstract

There is provided an underground water pumping pipe assembly, comprising: a first pipe coupled to an underground water motor pump; second to n-th pipes wherein the second pipe is coupled to the first pipe; a packing configured to wrap the first pipe; clamping bands, each band coupled to each first securing portion to fix the packing to the first pipe; and first coupling members to receive therein the first pipe and be coupled to the top and bottom of the packing respectively, wherein each first coupling member has a first member body and first and second guides formed on the body to be vertically arranged to be alternated with each other to define spaces therebetween, wherein an electrical wire and a wire rope for the motor pump extend through the spaces respectively.

1 . An underground water pumping pipe assembly, comprising:
 a first pipe coupled to an underground water motor pump (M);   second to n-th pipes (P 2 , P 3 , . . . , and Pn) wherein the second pipe is coupled to the first pipe, wherein the first to n-th pipes are coupled to each other in series;   a packing configured to wrap the first pipe (P 1 ), wherein the packing includes first securing portions at a top and bottom thereof, an extension extending between the first securing portions, and vertically elongate cut-away portions formed in the extension;   clamping bands, each band coupled to each first securing portion to fix the packing to the first pipe (P 1 ); and   first coupling members to receive therein the first pipe (P 1 ) and be coupled to the top and bottom of the packing respectively, wherein each first coupling member has a first member body and first and second guides formed on the body to be vertically arranged to be alternated with each other to define spaces therebetween, wherein an electrical wire (E) and wire rope (W) for the motor pump (M) extend through the spaces respectively.   
     
     
         2 . The assembly of  claim 1 , wherein one of the first and second guides has a protrusion formed thereon, wherein each first coupling member is secured to each clamping band with the protrusion being fitted with the clamping band. 
     
     
         3 . The assembly of  claim 1 , wherein the packing has a plurality of extensions vertically arranged to be spaced from each other, wherein the packing has a second securing portion between adjacent extensions. 
     
     
         4 . The assembly of  claim 1 , further comprising: second coupling members coupled to tops of the first to n-th pipes (P 1 , . . . , and Pn) respectively, wherein each second coupling member has a second member body and third and fourth guides formed on the body to be vertically arranged to be alternated with each other to define further spaces therebetween, wherein the electrical wire (E) and wire rope (W) for the motor pump (M) extend through the further spaces respectively; and
 coupling tubes coupled to bottoms of the first to n-th pipes (P 1  . . . Pn) respectively, wherein each coupling tube is screw-coupled to each second coupling member adjacent thereto.   
     
     
         5 . The assembly of  claim 4 , wherein each second coupling member has an inwardly stepped portion formed at a vertical middle thereof to define an inner space of each second coupling member into upper and lower space portions, wherein the upper space portion receives a corresponding pipe (P 1 , P 2 , . . . , or Pn) and the lower space portion receives a corresponding coupling tube via a screw coupling.
