Technical Field

[0001] This utility model relates to the field of petroleum engineering technology, and in particular to a pipeline connector for a hydraulic perforation device for petroleum. Background Technology

[0002] Oil extraction refers to the act of digging and extracting oil from places where oil reserves exist. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well and then rise from the bottom of the well to the wellhead. In addition, perforation is an operation that uses special shaped charge equipment to enter the wellbore at a predetermined layer to make explosive openings, allowing fluids from the formation below the well to enter the hole. It is widely used in oil and gas fields and coal fields. Existing perforation equipment, especially modular perforation equipment, requires a connector for fixed connection when connecting cables. When installing a connector, both ends need to be fixed with sleeves. Most of the connection methods on the market are of this type. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for fixed sleeves at both ends during installation of a connector, and to provide a pipeline connector for a hydraulic perforation device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pipeline connector for a hydraulic perforation device for oil, comprising a sleeve, a first connecting pipe fixedly connected to the inner wall of the sleeve by threads, a second connecting pipe provided on the inner wall of the first connecting pipe, a cable pipe provided on the inner wall of the second connecting pipe, a limiting plate fixedly connected to the outer surface of the first connecting pipe, a movable frame provided on one side of the limiting plate, a movable frame movably connected to one side of the movable frame, a rotating structure provided on the outer surface of the movable frame, the rotating structure comprising a rotating plate, a retaining groove formed on the outer surface of the rotating plate, a rotating rod provided on the top of the rotating plate, a first rotating groove formed on the top of the rotating plate, a limiting groove formed on one side of the retaining groove, a movable slot formed on the outer surface of the movable frame, a second rotating groove formed on the outer surface of the second connecting pipe, and a retaining ring rotatably connected to the inner wall of the second rotating groove.

[0005] In a preferred embodiment, a connecting plate is engaged with the inner wall of the limiting groove, a movable plate is fixedly connected to the top of the connecting plate, a locking block is fixedly connected to the bottom of the connecting plate, and a spring is fixedly connected to the outer surface of the locking block.

[0006] In a preferred embodiment, the bottom of the limiting groove is provided with a telescopic groove, and one side of the telescopic groove is provided with a locking groove. The locking groove is opened into the inner wall of the movable groove, and the inner wall of the telescopic groove is fixedly connected to one end of the spring. Both the telescopic groove and the locking groove are engaged with the outer surface of the locking block.

[0007] In a preferred embodiment, the inner wall of the first connecting pipe is rotatably connected to the outer surface of the second connecting pipe via a second rotating groove.

[0008] In a preferred embodiment, the inner wall of the movable frame is fixedly connected to the outer surface of the first connecting tube, and the inner wall of the limiting frame is movably connected to the outer surface of the first connecting tube.

[0009] In a preferred embodiment, the two ends of the rotating rod are fixedly connected to the inner wall of the movable slot, and the inner wall of the first rotating slot is rotatably connected to the outer surface of the rotating rod.

[0010] In a preferred embodiment, the outer surface of the retaining ring is fixedly connected to the inner wall of the first connecting tube.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This utility model allows the two connecting parts to rotate simultaneously by setting opposite threads on the outer surfaces of the first and second connecting pipes. Since the limiting plate is fixedly connected to the movable frame, the limiting frame can be used as a rotation support point when the movable frame and its connection are rotated as a whole. In order to make the rotation of the first connecting pipe more stable, a second connecting pipe is set for support. By setting a second rotating groove and a retaining ring, the second connecting pipe will not detach from the whole. By setting a movable slot, it is easy to set a rotation structure that drives the movable frame to rotate with less effort, pulling the movable frame to rotate as a whole. With the above settings, as long as the connection does not become loose, only one tightening is needed to tighten and reinforce both ends at the same time. Attached Figure Description

[0020] 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. Example 1

[0021] like Figures 1-5 As shown, this utility model provides a technical solution: a pipeline connector for a hydraulic perforation device for oil, including a sleeve 1. A first connecting pipe 2 is threadedly fixed to the inner wall of the sleeve 1.

A second connecting pipe 3 is disposed on the inner wall of the first connecting pipe 2, and a cable conduit 4 is disposed on the inner wall of the second connecting pipe 3. A limiting plate 5 is fixedly connected to the outer surface of the first connecting pipe 2. A movable frame 6 is disposed on one side of the limiting plate 5, and the inner wall of the movable frame 6 is fixedly connected to the outer surface of the first connecting pipe 2. A limiting frame 7 is movably connected to one side of the movable frame 6, and the inner wall of the limiting frame 7 is movably connected to the outer surface of the first connecting pipe 2. The movable frame 6 has a rotating structure 8 on its outer surface. The rotating structure 8 includes a rotating plate 81 with a snap-fit ​​groove 82 on its outer surface. A rotating rod 83 is located on the top of the rotating plate 81, and both ends of the rotating rod 83 are fixedly connected to the inner wall of the movable slot 9. A first rotating groove 84 is located on the top of the rotating plate 81, and the inner wall of the first rotating groove 84 is rotatably connected to the outer surface of the rotating rod 83. A limit groove 85 is located on one side of the snap-fit ​​groove 82. The movable frame 6 has a movable slot 9 on its outer surface. The second connecting pipe 3 has a second rotating groove 10 on its outer surface, and a retaining ring 11 is rotatably connected to the inner wall of the second rotating groove 10. The outer surface of the retaining ring 11 is fixedly connected to the inner wall of the first connecting pipe 2.

[0022] In this embodiment, by setting a first connecting pipe 2 and a second connecting pipe 3, the connecting parts at both ends can rotate simultaneously. Two first connecting pipes 2 are symmetrically arranged, with the threads on the surfaces of the two first connecting pipes 2 in opposite directions. The sleeves 1 on both sides also have opposite threads. By setting a limiting plate 5, the translation of the limiting frame 7 is restricted. Since the limiting plate 5 is fixedly connected to the movable frame 6, the limiting frame 7 can be used as a rotation support point when the movable frame 6 and its connected components rotate. Two limiting plates 5 and two limiting frames 7 are also symmetrically arranged, located on both sides of the movable frame 6, engaging with but not fixed to the limiting frame 7. The movable frame 6... The limiting plate 5 and the first connecting pipe 2 are fixedly connected and can rotate simultaneously. To make the rotation of the first connecting pipe 2 more stable, a second connecting pipe 3 is provided for support. By setting the second rotating groove 10 and the retaining ring 11, the second connecting pipe 3 will not detach from the whole. By setting the movable groove 9, it is easy to set a rotating structure 8 that drives the movable frame 6 to rotate with less effort.

[0024] In this embodiment, in order to prevent the rotating structure 8 from detaching from the movable frame 6 during construction, a telescopic groove is opened at the bottom of the limiting groove 85, and a slot is opened at the opposite position of the telescopic groove. The locking block 13 can move back and forth in the telescopic groove and the slot through the moving plate 12, and the movement is restricted and supported by the spring 14 on the tail side of the locking block 13.

[0025] Working principle:

[0026] like Figures 1-5 As shown, during installation, after the cable pipes 4 connecting the two perforating guns are installed, the sleeves 1 on both sides are placed at the first connecting pipes 2 on both sides respectively. The moving plate 12 is pushed backward, and the locking block 13 is disengaged from the slot. Then, the locking slot 82 is engaged to lift the rotating plate 81. The rotating plate 81 is used as an auxiliary tool to tighten the connecting pipes on both sides. Since the threads on both sides are reversed, the first connecting pipes 2 on both sides can be tightened inside the sleeve 1 when rotated clockwise.
