Description

Technical Field

[0001] The invention relates to the technical field of maintenance, and in particular to a water-stopping structure with water-swelling glue for maintenance. Background Art

[0002] The pipeline is long and may be damaged by man-made and natural disasters at any time. Therefore, line inspection and maintenance work must be carried out regularly. In addition, there is a special pipeline maintenance team equipped with necessary mobile equipment, earthwork construction machinery, welding and sealing equipment, and communication tools, so as to be ready for emergency repairs at any time.

[0003] Water supply pipes and drainage pipes have been buried underground for a long time. After a long period of erosion by microorganisms and plant roots, the pipes are prone to rupture during use. Once ruptured, water will seep out of the pipes. If inspection and maintenance are carried out immediately, the valves need to be closed to stop the operation of the pipes. If the water supply is stopped during a period of intensive water use, people's normal lives will be affected to a certain extent. If the water supply is not stopped, the pipes will continue to seep, resulting in a waste of water resources. Therefore, in order to solve such problems, we have proposed a water-stopping structure with water-swelling glue for maintenance. Summary of the invention

[0004] The invention provides a water-stop structure with water-swelling glue for maintenance, which solves the problem that water outage during water-intensive period during pipeline maintenance affects people's normal life and that failure to stop water leads to waste of water resources.

[0007] Preferably, a telescopic spring is sleeved on the circumferential side wall of the connecting shaft, one end of the telescopic spring is fixedly connected to the fixed plate, and one end of the telescopic spring away from the fixed plate is fixedly connected to the movable plate.

[0008] Preferably, a threaded rod is provided at the top end of the mounting plate, the threaded rod passes through the mounting plate and extends to the outside, and a nut is provided at the bottom end of the mounting plate, the nut matches the threaded rod.

[0009] Preferably, a buckle is fixedly mounted on the bottom end of one side of the limiting ring, and inner walls of the movable plate and the fixed plate are provided with a slot, and the slot matches the buckle.

[0010] Preferably, a connecting shaft is fixedly mounted on the end of the limiting ring, the connecting shaft is symmetrically arranged with respect to the central axis of the limiting ring, and the connecting shaft is rotatably connected to the movable plate and the fixed plate.

[0011] Preferably, an expansion rubber body is arranged at the top of the placement plate, and a limiting plate is arranged at the top of the inner wall of the limiting ring, and the limiting plate matches the expansion rubber body.

[0012] The beneficial effects of the present invention are:

[0013] 1. Place the expansion rubber body on the placement plate, then move the limit ring, the limit ring drives the connecting shaft to rotate in the moving plate, and then the expansion rubber body is limited in the moving plate by the limit plate, and then the limit ring is fixed in the moving plate by inserting the buckle into the slot, so that the expansion rubber body can be effectively fixed, and the expansion rubber body can be replaced more conveniently.

[0014] 2. By pulling the installation plate, the installation plate drives the movable plate to move, and then the movable plate drives the placement plate to move, and the placement plate drives the expansion rubber body to move, and then the expansion rubber body is aligned with the leakage of the water pipe, and then the expansion rubber body will expand when it meets water, thereby effectively preventing the leakage of the water pipe.

[0015] 3. The elastic force of the telescopic spring drives the movable plate to move, and then the movable plate drives the mounting plate to move, and then the movable plate and the fixed plate are fixed to the water pipe through the threaded rod, so that the pipeline can be repaired when water use is not intensive, and the waste of water resources is reduced.

[0016] In summary, the device can effectively prevent leakage of water pipes, and can repair pipes when water usage is not intensive, while reducing the waste of water resources. The expansion rubber body is also relatively easy to replace and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
