In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0036] like Figure 1 and Figure 2As shown, the present application provides an easy-to-use crack repair device for an oil pipeline 40, the crack repair device includes a plurality of arc-shaped sealing blocks 10, adjacent arc-shaped sealing blocks 10 are detachably connected, and a plurality of arc-shaped sealing blocks 10 are connected end to end to form a repair ring, a storage box 20 is provided on the outer side of the arc-shaped sealing block 10, a drainage port 11 is provided on the inner side of the arc-shaped sealing block 10 close to the oil pipeline 40, a guide tube 21 is provided between the drainage port 11 and the storage box 20, the guide tube 21 is provided inside the arc-shaped sealing block 10, and a drainage channel 31 connected to the drainage port 11 is provided on the inner wall of the arc-shaped sealing block 10.

[0037] Among them, Figure 1 As shown, the arc-shaped sealing block 10 is an arc-shaped strip structure. In an optional embodiment, the crack repair device can be composed of four arc-shaped sealing blocks 10. The four arc-shaped sealing blocks 10 are connected end to end to form an annular repair device. If there is a crack in the oil pipeline 40, one of the arc-shaped sealing blocks 10 repairs the crack, and other structures assist the arc-shaped sealing block 10 to seal. The end-to-end connection improves the tightness of the connection, thereby improving the extrusion of the arc-shaped sealing block 10 on the cylindrical oil pipeline 40, thereby improving the sealing effect.

[0038] The storage box 20 may store leak-proof glue or sealant inside, which are viscous substances used to fill cracks and can form a strong seal after solidification, thereby filling the gap between the arc-shaped sealing block 10 and the oil pipeline 40 during repair, thereby improving the sealing effect.

[0039] Furthermore, if Figure 2 As shown, the crack repair device also includes a plugging layer 30, which is arranged on the inner wall of the arc-shaped blocking block 10, and a drainage channel 31 is arranged around the plugging layer 30.

[0040] For the plugging layer 30, it can adopt a plugging bag or plugging ball structure, which are flexible bags or balls specially designed to seal pipe cracks, usually made of oil-resistant and chemical-resistant materials. As an optional embodiment, the present application can adopt the structure of a plugging bag, which is a flexible bag usually made of high-strength, chemical-resistant materials such as rubber or silicone. The design of the bag allows it to be compressed to a very small size so that it can reach the leak point through a narrow space. Once in place, the bag can be inflated by compressed air or water to form a seal to prevent fluid flow.

[0041] In addition, the plugging layer 30 includes a compressed state and a relaxed state, and the surface area of ​​the plugging layer 30 in the compressed state is not greater than the surface area of ​​the arc-shaped plugging block 10 close to the oil pipeline 40 .

[0042] When in use, the arc-shaped sealing block 10 is first used to perform extrusion repair on the physical level, and then the structure of the leak-proof layer 30 is inflated to cause it to gradually collide between the arc-shaped sealing block 10 and the oil pipeline 40, further narrowing the gap between the two and improving the sealing effect.

[0043] For the structure for inflating the leak-proof layer 30, an inflation port may be provided on the side, and the inflation port is connected to the inflation device for inflation. The structure is convenient to operate and has a simple structure. The structure can be quickly installed to reduce leakage time and potential damage. The structure also has the property of being able to deform, and the structure can be adapted to various pipe diameters and shapes, as well as different types of fluids and gases.

[0044] As for its surface area, it is better to be slightly smaller than the surface area of ​​the arc-shaped blocking block 10, and a drainage channel 31 can be set around the plugging layer 30, so that while the plugging layer 30 is sealed, the sealing liquid flowing in the drainage channel 31 can further improve the fixing effect.

[0045] As a preferred implementation of the present application, Figure 1 As shown, the arc-shaped blocking block 10 includes a blocking portion 12 and a telescopic portion 13 , and the telescopic portion 13 is arranged on both sides of the blocking portion 12 .

[0046] The structure of the telescopic portion 13 can have the same bending angle as the sealing portion 12 to ensure that it can be tightly attached to the outer wall of the oil pipeline 40 during sealing. The telescopic portion 13 enables the arc-shaped sealing block 10 to further adapt to oil pipelines 40 of different sizes, and allows the device to be adjusted according to the actual situation of the crack while maintaining stability, further improving the repair effect.

[0047] Furthermore, the storage box 20 is arranged on the outer wall of the sealing part 12 near one end of the telescopic part 13, and the guide tube 21 is arranged inside the sealing part 12, so that the sealant guided by the guide tube 21 can further reinforce the repaired hole after the sealing part 12 is sealed.

[0048] In addition, if Figure 2 As shown, a telescopic opening 14 is provided on one side of the telescopic portion 13, and a guide rod 15 is provided at one end of the sealing block adjacent to the telescopic portion 13. The guide rod 15 is slidably connected to the telescopic opening 14. It can be understood that the guide rod 15 should be an arc-shaped rod structure, the telescopic opening 14 should have a certain depth, and the interior should also be an arc-shaped structure to ensure that the telescopic portion 13 can be telescoped on the arc-shaped structure of the arc-shaped sealing block 10 itself, thereby improving the sealing range of the entire crack repair device.

[0049] In a preferred embodiment, adjacent telescopic parts 13 are detachably connected, which facilitates fixing the entire repair device on the surface of the oil pipeline 40 on the one hand, and on the other hand, the detachable connection structure can make the equipment connection simpler and facilitate replacement and maintenance.

[0050] Specifically, the connection between two adjacent telescopic parts 13 is provided with an arc-shaped docking piece, and the arc-shaped docking piece is provided with a locking opening 16, and the locking opening 16 is detachably connected with a locking column 17, such as Figure 2 As shown, the locking port 16 can adopt a threaded structure, and the locking column 17 can adopt a bolt structure, and the threaded cooperation of the two facilitates disassembly and assembly.

[0051] As a preferred implementation of the present application, Figure 1 The crack repair device shown also includes an auxiliary rod 18, which is connected to the outer wall of the arc-shaped blocking block 10 and is connected to the storage box 20, wherein the auxiliary rod 18 can be a telescopic rod, and the auxiliary rod 18 is provided with a switch buckle at one end of the arc-shaped blocking block 10, and an opening and closing door is provided in the storage box 20, the switch buckle is linked to the opening and closing door, and the auxiliary rod 18 can be rotatably connected to the storage box 20, so that during use, the arc-shaped blocking block 10 can be penetrated into a gap that is difficult to install or a higher position through the auxiliary rod 18, and the auxiliary rod 18 can cooperate with other lifting structures or supporting structures to facilitate the support of the arc-shaped blocking block 10.

[0052] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0053] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
