Description
Technical Field
[0001] The utility model relates to the technical field of pipeline pressure plugging, and more specifically, to a temporary leak plugging device for a hydropower station pipeline. Background Art
[0002] A temporary leak-stopping device for hydropower station pipelines is a technical device that can quickly and effectively stop leaks in the technical water supply pipelines of a hydropower station, ensuring the normal operation of the hydropower station equipment. Pipeline pressure plugging technology is particularly important for temporarily stopping leaks in technical water supply pipelines in hydropower stations. This technology can quickly and effectively seal leaks without shutting down the plant, ensuring the normal operation of the hydropower station.
[0003] When a pipeline leak occurs at a hydropower station, the technical water supply must be temporarily shut off while the pipe is repaired and welded to ensure the welding process proceeds normally. However, the generator set needs to continue generating electricity, and the technical water supply cannot be immediately stopped, otherwise it could easily cause the generator set to malfunction. Therefore, repair work must be performed in an environment with a continuous leak. However, conventional temporary pipeline leak-proofing devices are inconvenient to use. When a pipeline leaks, the high water pressure makes it difficult to tighten the plugging pipe. Therefore, a temporary leak-proofing device for hydropower station pipelines has been developed to address this problem. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a temporary leak-proof device for a hydropower station pipeline. The technical problem to be solved by the present invention is: when welding the pipeline of a hydropower station, since the unit needs to generate electricity continuously, it is necessary to repair the leak in an environment of continuous leakage. The common temporary leak-proof device for pipelines has the problem that when a leak occurs in the pipeline, the water pressure is high and the common leak-proof pipe is difficult to lock.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a temporary leak-proof device for a hydropower station pipeline, comprising a pipeline body, a sleeve assembly being sleeved on the outer surface of the pipeline body, and a sealing assembly being provided in the inner cavity of the sleeve assembly;
[0006] The socket assembly includes a first half ring, a second half ring is provided on one side of the first half ring, a hinge is provided between the first half ring and the second half ring, the inner walls of the first half ring and the second half ring are both provided with sealing ring grooves, the inner walls of the first half ring and the second half ring are provided with multiple strip ring grooves, the outer side of the end of the second half ring away from the hinge is fixedly connected to the first connecting frame, the outer side of the end of the first half ring away from the hinge is fixedly connected to the second connecting frame, a rotating column is provided on the inner side of the first connecting frame, the top of the rotating column is fixedly connected to a threaded column, the outer surface of the threaded column is rotatably connected to the rotating column, and the top of the rotating column is fixedly connected to a rotating handle.
[0007] In a preferred embodiment, the sealing assembly includes a sealing ring plate, strip sealing rings are provided on both sides of the sealing ring plate, a sealing sheet is fixedly connected to one side of the strip sealing ring, a plurality of silicone protrusions are fixedly connected to the outer surface of the sealing ring plate, a nut column is fixedly connected to the outer side of the silicone protrusion, and a screw is provided on the inner side of the nut column.
[0008] In a preferred embodiment, the sealing ring plate is arranged in the sealing ring groove, and the screw rod penetrates the surfaces of the first half ring and the second half ring and is rotatably connected to the nut column on the surface of the sealing ring plate.
[0009] In a preferred embodiment, the inner wall surfaces of the first half ring and the second half ring are provided with two strip-shaped annular grooves, both sides of the rotating column are fixedly connected with rotating rods, and the rotating rods on both sides of the rotating column pass through the first connecting frame.
[0010] In a preferred embodiment, the strip sealing rings are all arranged in strip ring grooves, and the sealing sheets are all in contact with the inner walls of the first half ring and the second half ring.
[0011] In a preferred embodiment, the sealing ring plate, the strip sealing ring, the sealing sheet and the silicone protrusion are all made of silicone.
[0012] The technical effects and advantages of this utility model are:
[0013] 1. The utility model is provided with a sleeve assembly. When used in the later stage, one side of the first connecting frame and the second connecting frame can lengthen the distance between the rotating column and the threaded column after rotation by rotating the rotating handle. After lengthening, the first half ring and the second half ring are rotatably connected to each other. Due to the high-pressure water sprayed at the pipeline, the first half ring and the second half ring are not so easy to close. At this time, by rotating the rotating column, the threaded column and the rotating column, the threaded column drives the rotating column to be stuck on the inner side of the second connecting frame. By rotating the rotating handle, the rotating column and the threaded column are contracted and rotated. In this way, the first half ring and the second half ring can be easily closed even in a high-pressure environment. After closing, the surfaces of the first half ring and the second half ring are fixed by bolts, which solves the problem that the common temporary leak-proof device for pipelines is difficult to lock due to the high water pressure when the pipeline leaks.

When used in the later stage, the sealing ring plate can be fitted with the inner walls of the first half ring and the second half ring by a screw, and then the sealing ring plate can be tightly fitted with the inner walls of the first half ring and the second half ring by rotating the screw on the outer surfaces of the first half ring and the second half ring, and then the strip sealing ring can be inserted into the strip ring groove. In this way, the sealing performance can be guaranteed in the later stage, and the sealing ring plate, the strip sealing ring and the sealing sheet can be replaced in the later stage, thereby improving the sealing performance in the later stage.
