A sealing device for preventing pollution of underground water in a underground water well is provided to maintain a heat pump system feeding underground water as heat source through a plurality of pipes by allowing a user to disassemble an intake pipe and a drain pipe easily. A sealing device for preventing pollution of underground water in an underground water well comprises a assembly body(2), a pressing drum(5), a upper fastener(3), a lower fastener(4), an intake pipe(10) and a drain pipe(15). The assembly body is linked to a bottom pipe(1) forming a underground well. The pressing drum is linked to the assembly body by the pressing plate. The upper fastener is interposed between the assembly body and the pressing drum and provided with a connection pipe(13) therein. The lower fastener is interposed between the assembly body and the pressing drum and provided a connection pipe(14) having extra path therein. The intake pipe and the drain pipe connect with the connection pipes and links to the assembly body. |
