[0002] In modern production, there are various pipelines for water, oil and gas, and in living facilities, there are water pipes, gas pipes and heating pipes. Due to various reasons such as foundation sinking, external impact and human damage, pipelines are broken, especially weld cracks, which cause oil, gas and water leakage. They must be repaired in time, otherwise it will not only waste resources and affect production and life, but also cause environmental pollution.

[0003] The existing emergency repair method for pipelines usually uses two curved plates to fit the surface of the pipeline, and then the two curved plates are locked and fixed by bolts. However, this remedial method is slow to implement and often requires multiple people to operate. It cannot achieve a quick leak plugging effect. Moreover, the curved plates used in the above-mentioned equipment cannot change the curvature according to the actual size of the pipeline. Therefore, secondary leakage is prone to occur after plugging, and the applicability is poor. Utility Model Content

[0022] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0024] Combination Figure 1-4 As shown, a glass fiber reinforced plastic pipeline leak plugging device comprises:

[0025] The self-locking device 1 comprises a rectangular housing 11, a side wall of which is provided with an opening that penetrates the housing 11, a locking wheel 12 is rotatably mounted inside the housing 11, and different tooth blocks are respectively provided at both ends of the locking wheel 12;

[0026] The flexible belt 2 is in the shape of a long strip, one end of which is fixedly connected to the bottom of the self-locking device 1, and the other end is inserted into the interior of the self-locking device 1 along the opening to form a circular ring. A water blocking pad 3 is also provided on the flexible belt 2, and the water blocking pad 3 is tightly fitted to the pipe wall through the self-locking device 1 to complete the sealing.

[0027] Specifically, the locking wheel 12 is disposed in the housing 11 through a rotating shaft, and one end is arranged above the opening and is provided with a gear-shaped tooth block, and the other end is provided with a ratchet-shaped tooth block. The two different sets of tooth blocks are integrally formed with the locking wheel 12.

[0028] In this embodiment, the surface of the flexible belt 2 should also be provided with a mounting groove, which extends along the flexible belt 2 into a long strip, and a rack 21 is embedded in the mounting groove. The rack 21 is meshed with the gear-shaped tooth block on the locking wheel 12. Therefore, when the flexible belt 2 passes through the inside of the opening, the rack 21 can drive the locking wheel 12 to rotate, thereby reducing the inner diameter of the ring formed by the flexible belt 2, which is convenient for use in sealing pipes of various sizes.

[0029] In order to prevent the flexible belt 2 from slipping out and ensure the tight fit between the water blocking pad 3 on the flexible belt 2 and the pipe wall, a pawl 13 should be provided inside the shell 11 at one end close to the ratchet gear, and the rotation direction of the entire locking wheel 12 is limited by the pawl 13. Therefore, after the flexible belt 2 is pulled until the water blocking pad 3 fits the pipe wall, the flexible belt 2 will be automatically locked due to the ratchet structure, thereby completing the fixation. The entire operation process only requires one person to complete, and it is very convenient to use.

[0030] In this embodiment, the loosening of the ratchet structure should also be considered to facilitate disassembly by the staff. Therefore, a slide groove 16 is provided on the inner top of the shell 11, and a mounting seat 14 is provided at the end of the pawl 13. The top surface of the mounting seat 14 is slidably inserted into the slide groove 16 through an insertion strip 15, and the top surface of the insertion strip 15 is provided with a cylindrical protrusion. The top surface of the shell 11 is provided with a strip groove 17, which extends downward and is connected to the slide groove 16. Therefore, the protrusion extends upward into the strip groove 17. The staff can drive the mounting seat 14 to slide left and right by toggling the protrusion, so that the ratchet-shaped tooth block and the pawl 13 are separated, the limiting effect is lost, and the disassembly is completed.

[0031] In the above structure, in order to prevent the mounting seat 14 of the pawl 13 from sliding randomly, a spring should be installed in the slide groove 16. The spring is mainly used to squeeze the insertion strip 15 on the mounting seat 14 toward one end. When the manual removal is completed, the pawl 13 will also return to its original position through the spring and limit the ratchet-shaped gear again.

[0032] In order to further enhance the fitting effect between the shell 11 and the pipe wall, an elastic layer should be provided on the bottom surface of the shell 11. The elastic layer and the water blocking pad 3 are made of the same rubber material, and the surface is provided with anti-slip patterns and a number of small suction nozzles. When squeezed, the elastic pad will move completely along the shape of the pipe wall, and the suction nozzle will discharge the internal air, thereby fitting tightly with the pipe wall, which can not only avoid the rigid structure of the outer shell from being squeezed and deformed, but also make the connection between the shell 11 and the pipe wall closer.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
