Description

Technical Field

[0001] This utility model relates to the field of oil pipe perforation repair technology, specifically a portable oil pipe perforation repair device. Background Technology

[0002] In the petroleum, chemical, and energy industries, perforation and leakage of oil pipelines due to corrosion and mechanical damage are common failures. To reduce downtime losses, mechanical clamping repair devices are widely used for temporary pressurized leak sealing.

[0003] Existing devices mostly adopt a split rigid flange or arc-shaped pressure plate assembly structure. The curvature is prefabricated according to a fixed pipe diameter, which has poor applicability and insufficient portability. In addition, the installation is time-consuming due to the bolt fastening design. Utility Model Content

[0004] The purpose of this invention is to provide a portable oil pipe perforation repair device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable oil pipe perforation repair device includes an arc-shaped elastic stainless steel sheet, a sealing mechanism, and a fixing mechanism. Both ends of the arc-shaped elastic stainless steel sheet are connected to bases. The lower surface of the arc-shaped elastic stainless steel sheet is connected to the sealing mechanism, which includes a sponge rubber pad and a rubber gasket. The lower surface of the arc-shaped elastic stainless steel sheet is fixedly connected to the sponge rubber pad, and the lower surface of the sponge rubber pad is fixedly connected to the rubber gasket. The two bases are connected to the fixing mechanism, which includes an elastic stainless steel cable tie and a ratchet-type steel strap lock. The side of one base is fixedly connected to the elastic stainless steel cable tie, and the ratchet-type steel strap lock is rotatably connected to the other base.

[0007] As a further embodiment of this utility model: the upper surface of the arc-shaped elastic stainless steel sheet is provided with shallow ripples.

[0008] As a further embodiment of this utility model, a sealing adhesive layer is provided on the lower surface of the rubber gasket.

[0011] As a further embodiment of this utility model: two symmetrically arranged fluorescent identification strips are fixedly connected to the upper surface of the arc-shaped elastic stainless steel sheet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an arc-shaped elastic stainless steel sheet that can deform and conform to the pipeline, making it convenient for sealing oil pipes of different diameters and improving the applicability of the device. Through a double-layer sealing mechanism composed of a sponge rubber pad and a rubber gasket, a softer sponge rubber pad is placed on the rubber gasket to help compensate for minor unevenness and improve the sealing effect. Furthermore, the device has a compact and lightweight structure, making it easy to use and carry. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 In this embodiment of the utility model, a portable oil pipe perforation repair device includes an arc-shaped elastic stainless steel sheet 1, a sealing mechanism, and a fixing mechanism.

[0020] In the specific implementation process, such as Figure 1 and Figure 2 As shown, both ends of the arc-shaped elastic stainless steel sheet 1 are connected to a base 2. A sealing mechanism is connected to the lower surface of the arc-shaped elastic stainless steel sheet 1. The sealing mechanism includes a sponge rubber pad 6 and a rubber pad 7. The sponge rubber pad 6 is fixedly connected to the lower surface of the arc-shaped elastic stainless steel sheet 1, and the rubber pad 7 is fixedly connected to the lower surface of the sponge rubber pad 6. A fixing mechanism is connected to the two bases 2. The fixing mechanism includes an elastic stainless steel cable tie 4 and a ratchet-type steel band lock 3. The elastic stainless steel cable tie 4 is fixedly connected to the side of one base 2, and the ratchet-type steel band lock 3 is rotatably connected to the other base 2.

[0021] It should be noted that during use, the curved elastic stainless steel sheet 1 is placed at the perforation of the oil pipe. The pre-bent curved elastic stainless steel sheet 1 conforms to oil pipes of different diameters through its own deformation. Then, the elastic stainless steel cable tie 4 is tightened by the ratchet-type steel band locker 3 to generate radial pressure, which drives the double-layer sealing mechanism composed of sponge rubber pad 6 and rubber gasket 7 to compress and deform, fill the perforation and block leakage. In summary, this device can conform to the pipeline through the deformation of the curved elastic stainless steel sheet 1, which is convenient for sealing oil pipes of different diameters and improves the applicability of the device. The double-layer sealing mechanism composed of sponge rubber pad 6 and rubber gasket 7, with a softer sponge rubber pad 6 on the rubber gasket 7, helps to compensate for minor unevenness and improves the sealing effect. In addition, the device is small and lightweight, making it easy to use and carry.

[0022] refer to Figure 1 As shown, the upper surface of the arc-shaped elastic stainless steel sheet 1 is provided with shallow ripples, which improves the bending stiffness of the arc-shaped elastic stainless steel sheet 1 and suppresses high-pressure bulging deformation.

[0023] refer to Figure 3 As shown, the lower surface of the rubber gasket 7 is provided with a sealant layer 8. Through the provided sealant layer 8, this layer of adhesive can better fill the minor unevenness and corrosion on the surface of the pipe during installation, thereby improving the initial sealing performance.

[0024] refer to Figure 3 As shown, the lower surface of the sealant layer 8 is provided with an anti-stick release film 9. The anti-stick release film 9 isolates the sealant layer 8, and can be easily removed for use.

[0025] The lower surface of the elastic stainless steel cable tie 4 is provided with anti-slip texture. When in use, the lower surface of the elastic stainless steel cable tie 4 fits against the pipe, increasing friction and making the device more stable when fixed.

[0026] refer to Figure 1 As shown, two symmetrically arranged fluorescent marking strips 5 are fixedly connected to the upper surface of the arc-shaped elastic stainless steel sheet 1. The fluorescent marking strips 5 emit light in dark environments (night, underground) to mark the location of the device and facilitate timely location of the perforation repair point.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
