DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Such asFigures 1 to 6 As shown in the figure, a repair structure for a leaking hole inside a steel pipe includes a repair rod 1. On the outer side of the rod body of the repair rod 1, two groups of symmetrically arranged rotating grooves 11 are provided. The rotating grooves 11 are through grooves. A connecting plate 2 is hinged to the non-through end of the rotating groove 11. The connecting plates 2 are arranged opposite to each other in pairs. On the outer side of one end of the repair rod 1 away from the connecting plate 2, a water-stop rubber pad 3 and a steel washer 7 are sequentially sleeved. A threaded groove 13 is opened in the middle of the repair rod 1. A threaded rod 6 is threadedly connected in the threaded groove 13. A T-shaped sleeve 5 is fixedly connected to the outer side of the threaded rod 6. The bottom surface of the T-shaped sleeve 5 abuts against the steel washer 7.

[0023] As Figures 1 to 6 shown, when the repair structure for the leaking hole inside the steel pipe in the present utility model is in use, the user can rotate the T-shaped sleeve 5 to drive the threaded rod 6 to separate from the threaded groove 13 in the repair rod 1. Then, the steel washer 7 and the water-stop rubber pad 3 are sequentially taken out from the rod body of the repair rod 1.

[0024] Then, the end of the repair rod 1 can be passed through the hole in the pipeline 9, and the connecting plate 2 can be rotated or the connecting plate 2 can be rotated out of the rotating groove 11 by gravity. At this time, it is not necessary to rotate the connecting plate 2 completely to 90 degrees. By pulling the repair rod 1, the connecting plate 2 can be made to completely fit the outer wall of the pipeline 9. The hinged end of the connecting plate 2 is restricted by the rotating groove 11 and can only be rotated from the vertical state to the perpendicular state.

[0025] Then, the water-stop rubber pad 3 and the steel washer 7 are sequentially sleeved on the outer side of the repair rod 1, so that the water-stop rubber pad 3 completely seals the hole.

[0026] Then, the T-shaped sleeve 5 is sleeved on the outer side of the repair rod 1, and at the same time, the T-shaped sleeve 5 is rotated, so that the threaded rod 6 rotates in the threaded groove 13, the threaded rod 6 is threadedly connected in the threaded groove 13, and the bottom surface of the T-shaped sleeve 5 abuts against the steel washer 7. As the threaded rod 6 rotates in the threaded groove 13, the T-shaped sleeve 5 can be made to squeeze the steel washer 7 tighter and tighter, and further the steel washer 7 squeezes the water-stop rubber pad 3 tighter, so that the water-stop rubber pad 3 can seal the leaking part.

[0027] Through the mutual cooperation of the repair rod 1, the rotating connecting plate 2, the water-stop rubber pad 3, the steel washer 7, the T-shaped sleeve 5 and the threaded rod 6, the connecting plate 2 can fix the repair rod 1 at the hole of the pipeline 9, the water-stop rubber pad 3 can seal, and the repair is realized. The steel washer 7 squeezes the water-stop rubber pad 3 to strengthen the sealing force, and in cooperation with the threaded rod 6, the repair rod 1 is tightened to improve the sealing effect.

[0028] As Figure 1 , Figure 3 and Figure 4 shown, a plurality of annular rubber grooves 31 are opened on one side of the water-stop rubber pad 3 away from the steel washer 7, and glue injection holes 33 are penetrated through the annular rubber grooves 31.

[0029] Specifically, after the water-stop rubber gasket 3 is sleeved on the outside of the repair rod 1, an adhesive can be injected through the glue injection hole 33 so that the annular glue groove 31 is filled with the adhesive, enabling the water-stop rubber gasket 3 to be bonded to the inner wall of the pipeline 9. Furthermore, an isolation is formed between the annular glue groove 31 and the leak point, resulting in a better water leakage prevention effect. The multiple annular glue grooves 31 can not only achieve multiple reinforcement effects but also facilitate bonding at leak points with different diameters, improving the scope of application and flexibility of use.

[0030] As Figure 1 、 Figure 3 and Figure 4 shown, a plug 71 corresponding to the position of the glue injection hole 33 is fixedly connected to one side of the steel gasket 7 close to the water-stop rubber gasket 3.

[0031] Specifically, when the steel gasket 7 is sleeved on the outside of the repair rod 1, the plug 71 will just insert into the glue injection hole 33 to block the glue injection hole 33, effectively preventing the glue from being extruded from the glue injection hole 33 due to the extrusion of the steel gasket 7, which may reduce the sealing effect of the water-stop rubber gasket 3.

[0032] As Figure 1 、 Figure 3 and Figure 4 shown, two groups of symmetrically arranged sealing strips 32 are fixedly connected to the inner wall of the water-stop rubber gasket 3, and the sealing strips 32 are correspondingly arranged with the rotating grooves 11.

[0033] Specifically, when the water-stop rubber gasket 3 is sleeved on the outside of the repair rod 1, multiple sealing strips 32 in the inner ring of the water-stop rubber gasket 3 will correspondingly plug into the rotating grooves 11. The sealing strips 32 are made of the same material as the water-stop rubber gasket 3, and thus can be extruded in the rotating grooves 11 to effectively seal the rotating grooves 11.

[0034] As Figure 1 、 Figure 3 and Figure 4 shown, a finger ring 51 is fixedly connected to the outer wall end of the T-shaped sleeve 5. The provision of the finger ring 51 facilitates the rotation operation of the T-shaped sleeve 5 and the threaded rod 6.

[0035] As Figure 1 、 Figure 3 and Figure 4 shown, a sleeve 8 is sleeved on the outer wall of the T-shaped sleeve 5. A U-shaped cover 81 is fixedly connected to the bottom of the sleeve 8, and the annular inner wall of the U-shaped cover 81 is threadedly connected to the outer wall of the T-shaped sleeve 5.

[0036] Specifically, after the T-shaped sleeve 5 is fixed to the repair rod 1, the sleeve 8 and the U-shaped cover 81 can be threadedly connected to the outer wall of the T-shaped sleeve 5. With the arrangements of the sleeve 8 and the U-shaped cover 81, it is convenient to sleeve the T-shaped sleeve 5 and the repair rod 1, providing a certain protective effect, reducing the corrosion of the liquid in the pipeline 9 on the T-shaped sleeve 5, and extending the service life of the repair structure.

[0037] As Figure 1 , Figure 3 and Figure 4 shown, a sealing gasket 4 sleeving the outside of the repair rod 1 is connected to the bottom surface of the T-shaped sleeve 5. A U-shaped sealing ring 41 is fixedly connected to the outside of the sealing gasket 4, and the U-shaped sealing ring 41 abuts against the bottom surface of the inner wall of the U-shaped cover 81.

[0038] Specifically, when the sealing gasket 4 is sleeved on the bottom surface of the T-shaped sleeve 5, when the threaded rod 6 is gradually squeezed, the T-shaped sleeve 5 can be more tightly squeezed against the steel gasket 7 through the elasticity of the sealing gasket 4. At the same time, the sealing gasket 4 also plays a role in re-sealing the outside of the repair rod 1.

[0039] With the arrangement of the U-shaped sealing ring 41, when the U-shaped cover 81 is threadedly connected to the T-shaped sleeve 5, the U-shaped cover 81 can squeeze the U-shaped sealing ring 41, enabling the U-shaped cover 81 to form an effective seal inside.

[0040] As Figure 1 , Figure 3 and Figure 4 shown, a top block 12 is fixedly connected to the top of the repair rod 1, and the top of the top block 12 is conical. The setting of the top block 12 can facilitate the repair rod 1 to play a certain guiding role when entering the hole in the pipeline 9.

[0041] The repair structure in this solution can produce repair structures suitable for different diameters of leakage holes according to actual production, thereby facilitating the repair of different diameters of leakage holes in the pipeline 9.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
