[0002] During the industrial production process, equipment such as pipelines and containers often leak due to various reasons (such as corrosion, wear, material aging, improper operation, etc.). These leaks not only cause waste of resources, but may also pollute the production environment and even trigger safety accidents. Traditional leak - handling methods often require stopping the vehicle and reducing pressure, which not only interrupts the production process, causes economic losses, but may also increase safety risks due to medium release, temperature and pressure changes, etc.

[0003] With the continuous progress of industrial technology, the pressure - retaining leak plugging technology has emerged as the times require and has become an important means to solve the leakage problems of production devices. The pressure - retaining leak plugging technology can quickly plug and repair the leakage part without stopping the vehicle and reducing pressure, thus effectively ensuring the continuity and safety of production.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a new type of pressure plugging device for leaks, as Figures 1-6 shown, which includes a support assembly 1, a force-bearing assembly 2 and a sealing plate 3. The support assembly 1 includes a vertical rod 11 and a horizontal rod 12. One end of the horizontal rod 12 is provided with a welding end 13, and the welding end 13 is welded above the leak point 41 of the tank body 4. The other end of the horizontal rod 12 is provided with a nut 15. The force-bearing assembly 2 includes a threaded rod 21. The threaded rod 21 is horizontally arranged and is threadedly connected to the nut 15. One end of the threaded rod 21 is provided with a tapered thimble 22. A thimble groove 31 is arranged in the middle of the sealing plate 3. The tapered thimble 22 abuts against the thimble groove 31. A sealing groove 32 is arranged at the bottom of the sealing plate 3. An O-ring 33 is arranged in the sealing groove 32. The sealing plate 3 fits on the outside of the leak point 41 of the tank body 4. This device can quickly respond to leakage problems of various tanks, tank bodies, and large-diameter pipelines, and is not restricted by their planar or curved shapes, showing strong adaptability and flexibility. The support assembly is composed of a vertical rod and a horizontal rod, forming a 90° angle and being fixed by welding, enhancing the overall stability.

[0026] The addition of the support frame reinforcing rib further improves the tensile strength and durability of the device, ensuring a stable plugging effect even in a high-pressure environment. The threaded rod of the force-bearing assembly is closely matched with the nut on the support frame. By rotating the threaded rod, the pressure on the sealing plate can be precisely controlled, achieving effective plugging of the leak point. The design of the tapered thimble enables the pressure to be more evenly distributed on the sealing plate, improving the reliability and efficiency of plugging.

[0027] An O-ring is embedded in the specially designed sealing groove at the bottom of the sealing plate. When installed, the O-ring fits tightly with the sealing groove and deforms when the stress rod is tightened, thus forming a tight contact with the leakage surface and effectively preventing further penetration of the leakage medium. This multiple-sealing structure significantly improves the sealing effect and durability of the device. The cross-shaped handle design at one end of the stress rod facilitates the operator to quickly rotate the threaded rod, and the sealing plate is tightly attached to the leakage point through the conical thimble, realizing a quick and effective leak plugging operation and reducing the impact on the production process.

[0028] In this embodiment, the vertical rod 11 and the horizontal rod 12 are welded and fixed at a 90° angle, and the vertical rod 11 and the horizontal rod 12 are supported and fixed by the diagonal brace 14 to improve the overall strength of the support assembly 1.

[0029] Specifically, the other end of the threaded rod 21 is welded with a cross-shaped handle 23 to facilitate the screwing operation of the threaded rod 21.

[0030] Furthermore, the conical thimble 22 is of a conical structure, and the thimble groove 31 is adapted to the structure of the conical thimble 22. The depth of the thimble groove 31 is greater than the length of the conical thimble 22 to prevent the conical thimble 22 from coming out during screwing.

[0031] Furthermore, the surface shape of the sealing plate 3 is adapted to the outer wall shape of the groove body 4 to ensure good sealing.

[0032] Furthermore, convex rings 331 are installed on both the inner side and the outer top of the O-ring 33, and the shape of the sealing groove 32 is adapted to the convex rings 331 to improve the sealing effect between the O-ring 33 and the sealing groove 32.

[0033] Furthermore, both the O-ring 33 and the convex rings 331 are made of silicone material and can deform when being squeezed.

[0034] Furthermore, the cross-shaped handle 23 is of a cross structure and is provided with anti-slip patterns on the surface to improve the anti-slip effect.

[0035] When the novel pressure-bearing leak plugging device of the present utility model is in use, first, according to the specific position of the leakage point, the welded end 13 of the support assembly 1 is firmly welded to the upper side of the leakage point 41 of the groove body 4. In this way, the support assembly 1 is stably fixed on the groove body 4, providing a solid foundation for the subsequent leak plugging operation.

[0036] Then, the threaded rod 21 of the stress component 2 is horizontally passed through the nut 15 on the support assembly 1 and tightly cooperates with the nut 15. At this time, the conical thimble 22 at one end of the threaded rod 21 just abuts against the thimble groove 31 in the middle of the sealing plate 3. Since the depth of the thimble groove 31 is greater than the length of the conical thimble 22, the conical thimble 22 will not come out of the thimble groove 31 when the threaded rod 21 is screwed, ensuring the smooth progress of the leak plugging operation.

[0037] Then, start to turn the cross handle 23 at the other end of the threaded rod 21. Since the cross handle 23 has a cross structure and anti-slip lines are provided on its surface, the operator can easily turn the threaded rod 21 to gradually tighten it. During the turning process, the conical thimble 22 will exert a downward pressure on the sealing plate 3, causing the sealing plate 3 to closely fit outside the leakage point 41 of the tank body 4.

[0038] At the same time, the O-ring 33 in the sealing groove 32 at the bottom of the sealing plate 3 will also be squeezed and deformed. Since convex rings 331 are installed on both the inner side and the outer top of the O-ring 33, and the shape of the sealing groove 32 is adapted to the convex rings 331, the O-ring 33 can better fill the sealing groove 32 and form a tight contact with the leakage surface when being squeezed. In this way, the further penetration of the leakage medium is effectively blocked.

[0039] Finally, when the threaded rod 21 is tightened to a certain extent, the sealing plate 3 and the O-ring 33 together form a multi-sealing structure to completely block the leakage point 41. At this time, the pressure plugging device has successfully achieved a rapid and effective plugging of the leakage point of the tank body 4.

[0040] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
