Description

Technical Field

[0001] This utility model relates to the field of oil pipeline technology, specifically to an oil pipeline crack sealing device. Background Technology

[0002] Oil pipelines consist of oil pipes and their accessories, and are equipped with corresponding oil pump units according to the needs of the process flow. They are designed and installed into a complete pipeline system to complete the tasks of oil unloading and transportation. Oil pipelines often crack due to external forces or internal air pressure, resulting in oil leakage and unnecessary losses. Cracks in oil pipelines cannot be directly repaired by welding, and disassembling the oil pipeline, cleaning it, and then welding to repair the crack is very troublesome, time-consuming, and affects oil transportation. In order to repair cracks in oil pipelines, pipeline maintenance personnel will use pipeline plugs to seal the cracks.

[0003] Chinese patent application number 202420431098.5 discloses an oil pipeline crack sealing device, including a fixing pipe that can be fitted onto the outside of an oil pipeline. The fixing pipe has two sets of fixing bolts at both its upper and lower ends for fixed connection to the oil pipeline. It also includes a through groove at the front middle end of the fixing pipe, within which a sealing plate for sealing the crack is provided. Each of the upper and lower ends of the through groove has a pressing mechanism one for pressing the sealing plate, and the outer middle end of the through groove has a pressing mechanism two for pressing the sealing plate. The device features a through-groove at the front end of a fixed pipe, within which a sealing plate is installed to seal and repair pipe cracks. Pressing mechanisms one and two are located at the upper, lower, and middle ends of the through-groove, respectively. These mechanisms work together to press the sealing plate tightly against the oil pipeline crack, effectively sealing and repairing it. Furthermore, the sealing plate contains a filling groove and filling blocks, which, when used together, allow adjustment of the sealing area according to the crack size, preventing waste. The device is simple to use, highly flexible, and practical.

[0004] The oil pipeline crack plugging device requires the oil pipeline to be disassembled before the fixing pipe can be attached to the outside of the oil pipeline, which is cumbersome and reduces its usability. Therefore, we propose an oil pipeline crack plugging device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an oil pipeline crack sealing device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil pipeline crack sealing device, comprising an upper ring pipe, the interior of which has two corresponding second insertion slots, the interior of which has a second insertion block inserted, and a lower ring pipe fixedly connected between the two second insertion blocks. Both the upper and lower ring pipes are fixedly connected to two corresponding first sealing gaskets. The upper ring pipe has two corresponding upper sealing gaskets fixedly connected to its interior, and the outer side of each upper sealing gasket is fixedly connected to two corresponding first retaining pads. The lower ring pipe has two corresponding lower sealing gaskets fixedly connected to its interior, and the interior of each lower sealing gasket has two corresponding first retaining grooves, into which the first retaining pads are inserted.

[0007] Preferably, the lower ring tube has two corresponding first insertion slots inside, and the upper ring tube has two corresponding first insertion blocks fixedly connected to the outside, with the first insertion blocks inserted into the inside of the first insertion slots.

[0008] Preferably, two corresponding first connecting blocks are fixedly connected to the outer side of the upper ring tube, and a plug rod is fixedly connected to the bottom of the first connecting block. Two corresponding second connecting blocks are fixedly connected to the outer side of the lower ring tube, and a slot is opened inside the second connecting block, into which the plug rod is inserted.

[0009] Preferably, the second connecting block has a fixing bolt inside.

[0010] Preferably, the upper ring tube has an injection groove inside.

[0011] Preferably, the outer sides of the upper and lower ring tubes are provided with epoxy powder primer, adhesive layer, and polyethylene outer protective layer.

[0012] This utility model provides a crack sealing device for oil pipelines, which has the following beneficial effects: 1. This oil pipeline crack sealing device involves encircling the oil pipeline with an upper and lower ring pipe, inserting a rod into the slot, and securing it with bolts. Simultaneously, a first gasket is inserted into a first groove. Through the cooperation of the first sealing gasket, lower sealing gasket, first groove, upper sealing gasket, and first gasket, both ends of the upper and lower ring pipes are sealed, ensuring a tight seal. Oil-resistant silicone rubber, polyglycolic acid-based rubber, or nanoparticle-based rubber is then injected into the cavities inside the upper and lower ring pipes through an injection groove to seal the crack. This device is easy to install on the outside of the oil pipeline, improving its practicality. Attached Figure Description
