[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a long-distance water supply tunnel sealing device, comprising a device body, a slide rail is provided on the side wall of the device body, and a lock hole is connected to one side of the slide rail, a sealing colloid is distributed on one side of the device body, and a clamping strip is provided on the inner side wall of the sealing colloid, a locking rod is passed through the inner side of the clamping strip, and an auxiliary slide is sleeved on the outer side of one end of the locking rod, a return spring is fixedly connected to the surface of one end of the auxiliary slide, a sealing head is distributed on one end of the device body, and a sealing ring is sleeved on the outer surface of the sealing head, a threaded sleeve is fixedly installed on one end surface of the sealing ring, and a guide structure is distributed on one side of the threaded sleeve.

[0006] As an optimal technical solution of the present invention, the guide structure includes a guide rod, a limit block and a threaded groove. The guide rod is distributed on one side of the threaded sleeve, and a limit block is fixedly installed on one end of the guide rod. A threaded groove is provided on the inner side of one end of the threaded sleeve.

[0007] As an optimal technical solution of the present invention, a support rod is fixedly installed at one end of the device body away from the sealing head, and a fixing seat is welded to the other end of the support rod, a motor is fixedly installed at one end of the fixing seat away from the support rod, and a threaded rod is connected to the output end of the motor.
