Description

Technical Field

[0001] This utility model relates to the field of water conservancy maintenance technology, and in particular to a steel pipe welding and maintenance water blocking and diversion device. Background Technology

[0002] Currently, most of the steel pipes used by water companies are roadside pipelines or cable tray pipes. Due to the difficulty of repairing by breaking roads and the excessive load on vehicles, water leakage is serious. During the repair process, due to the aging and damage of the gates and their improper opening and closing, water leakage often occurs, requiring maintenance work to be carried out by opening the gates. Generally, water companies use one method: one is to put sand and soil into woven bags and build a cofferdam outside the welding point to block the water and weld it. However, when the water level in the pipeline rises and overflows the cofferdam, the water needs to be pumped out and the cofferdam needs to be rebuilt, which seriously affects the repair progress, repair quality, poses significant safety hazards, and causes water pollution.

[0003] Another method is to use airbags to block water, but when the water level in the pipe rises and the pressure increases, the airbags are easily pushed out, posing a great safety hazard to the welding process. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a steel pipe welded repair water blocking and diversion device to solve the issue.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0027] Example

[0028] Reference Figures 1-3 The present invention discloses a steel pipe welding repair water blocking guide, comprising a first circular plate 1 and a second circular plate 2 arranged concentrically, and a hollow rubber ring 3 sandwiched between the first circular plate 1 and the second circular plate 2. An air valve core for inflation is provided at the hollow rubber ring 3, and an inflation conduit 4 is connected to the air valve core. A through hole 5 is provided at the first circular plate 1 for the inflation conduit 4 to pass through. A water passage hole 6 is provided at the center of the first circular plate 1 and the second circular plate 2. A water passage pipe 7 is connected between the two water passage holes 6, and a drain hose can be connected between the water passage pipes 7.

[0029] The inflation conduit 4 serves as a channel connecting the air source and the hollow rubber ring 3, allowing compressed air from the outside to smoothly enter the hollow rubber ring 3 and inflate it. During use, the hollow rubber ring 3 tightly adheres to the inner wall of the pipe to achieve the purpose of blocking water. When the maintenance work is completed and air needs to be released, the inflation conduit 4 also serves as a channel for gas discharge, allowing for convenient and quick release of the gas inside the hollow rubber ring 3. This is existing technology and will not be described in detail here.

[0030] Furthermore, a circular ring 8 is provided between the first circular plate 1 and the second circular plate 2, and is concentrically arranged with the two. The circular ring 8 is welded to the second circular plate 2. The inner diameter of the hollow rubber ring 3 abuts against the outer diameter of the circular ring 8 and is fitted on the circular ring 8. The circular ring 8 can enhance the stability of the hollow rubber ring 3, so that it fits the inner wall of the pipe more evenly when it is inflated and expands, and prevents the hollow rubber ring 3 from falling off under the clamping of the first circular plate 1 and the second circular plate 2.

[0031] A plurality of connecting rods 9 are arranged in a uniform array about their center between the first circular plate 1 and the second circular plate 2. The connecting rods 9 are arranged horizontally, with one end passing through the first circular plate 1 and having an external thread and a connecting nut 10 at the external thread, and the other end being welded to the second circular plate 2.

[0032] The connection between the first circular plate 1 and the second circular plate 2 is easily disassembled and assembled by the external thread of the connecting rod 9 and the connecting nut 10, which facilitates the quick disassembly of the guide tube during maintenance or replacement of parts.

[0033] Furthermore, the rods of multiple connecting rods 9 are located on the inner wall of the ring 8. This arrangement allows the connecting rods 9 to support the ring 8, enabling it to maintain its shape stability and reduce deformation when subjected to pressure from the expansion of the hollow rubber ring 3.

[0034] On the side of the first circular plate 1 opposite to the second circular plate 2, a plurality of locking components 11 are arranged in a uniform array around the first circular plate 1, and the locking components 11 are located at the edge of the first circular plate 1. The uniform array distribution of the multiple locking components 11 can make the guide more stable in the pipeline, ensuring that the guide is subjected to uniform support force in all directions in the pipeline, and preventing the guide from shifting or loosening during maintenance. Setting the locking components 11 at the edge of the first circular plate 1 makes it convenient for workers to install and adjust. After the guide is put into the pipeline, workers can easily perform operations such as rotating the screw 14, so that the guide can be quickly and accurately fixed in the pipeline.

[0035] Specifically, the clamping assembly 11 includes an angle steel 12 fixed on the first circular plate 1, an additional component 13 fixed on the outside of the angle steel 12, and a screw 14 that is horizontally threaded to the angle steel 12 and the additional component 13. The multiple screws 14 are all arranged on the diameter of the first circular plate 1. By means of threaded connection, the screw 14 can be tightened against the inner wall of the pipe by adjusting the extension length of the screw 14, thus completing the clamping and fixing of the entire flow guide.

[0036] Furthermore, two handles are provided on the outer side of the first circular plate 1. The handles provide convenient gripping points, making it easier for workers to install or remove the flow guide into or from the pipe. In narrow or hard-to-reach places, the handles provide better control and ease of operation.

[0037] The working principle and beneficial effects of this utility model are as follows:

[0038] When welding is required on the pipe, the workers use the handle to clamp the entire flow guide into the pipe, and then connect the air source through the air inflator 4 to inflate the hollow rubber ring 3; during the inflation process, the hollow rubber ring 3 gradually expands until its outer wall tightly abuts against the inner wall of the pipe, thus achieving the water blocking function.

[0039] By rotating the screw 14, the screw 14 is moved outward until one end of the screw 14 is against the inner wall of the pipe, thus completing the fixation of the entire flow guide.

[0040] In this embodiment, the hollow rubber ring 3 can fit tightly against the inner wall of the pipe after inflation, effectively preventing water from entering the welding and maintenance area. Through effective water blocking and stable fixation, the guide can ensure the smooth progress of maintenance work. When the water level in the pipe gradually rises, a drain hose can be connected between the water pipes 7.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
