Description

Technical Field

[0001] This utility model relates to the field of oilfield development technology, and in particular to a leak-sealing device for oilfield energy extraction pipelines. Background Technology

[0002] In the process of oilfield energy extraction, pipelines serve as crucial carriers for transporting crude oil, natural gas, and other media. Due to long-term exposure to complex geological environments and harsh working conditions, pipelines are prone to corrosion and wear, which can lead to leaks. Once a leak occurs, it not only wastes energy but can also cause environmental pollution and safety hazards.

[0003] Currently, existing leak-sealing devices on the market suffer from problems such as poor sealing effect, complex operation, and limited applicability when dealing with oilfield pipeline leaks. For example, some traditional leak-sealing devices require large-scale disassembly and installation of pipelines, consuming a lot of manpower, material resources, and time, and are difficult to achieve effective sealing under high pressure and high flow conditions.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: traditional leak-sealing devices require large-scale disassembly and installation of pipelines, which consumes a lot of manpower, material resources and time; on the other hand, to address the above problems, a leak-sealing device for oilfield energy extraction pipelines is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing leak-sealing devices, which require extensive disassembly and installation of pipelines, consuming a large amount of manpower, material resources, and time. Therefore, this invention proposes a leak-sealing device for oilfield energy extraction pipelines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a leak-sealing device for oilfield energy extraction pipelines, comprising a fixed plate, four buffer rods fixedly installed on the lower surface of the fixed plate, a base plate fixedly connected to one end of the four buffer rods, a support plate fixedly connected to the surface of the fixed plate, an adjusting plate slidably connected inside the support plate, a first arc-shaped plate fixedly connected to the surface of the adjusting plate, a second arc-shaped plate rotatably connected to the first arc-shaped plate, a bolt threaded into the second arc-shaped plate, two threaded rods threaded into the arc surfaces of both the first and second arc-shaped plates, a clamping plate rotatably connected to one end of the threaded rods, a sealing gasket fixedly connected to one side of the clamping plate, an L-shaped plate fixedly connected to the side wall of the support plate, a sliding rod slidably inserted inside the L-shaped plate, several adjusting grooves opened on the surface of the adjusting plate, a pull plate fixedly connected to one end of the sliding rod, and the size of the sliding rod matching the size of the adjusting groove of the adjusting plate.

[0007] The aforementioned components achieve the following effects: by setting a buffer rod and a base plate under the fixed plate, the impact force on the device during the leak sealing process can be effectively buffered, improving stability; the support plate cooperates with the slidingly adjustable adjustment plate to facilitate the adjustment of the position of the first arc plate according to pipes of different diameters, enhancing the applicability of the device; the first arc plate and the rotatably connected second arc plate are fixed by bolts, facilitating quick opening and closing to adapt to different operating scenarios; the setting of the threaded rod, clamping plate, and sealing gasket can flexibly adjust the clamping force and sealing effect on the pipe, ensuring good leak sealing performance.

[0008] Preferably, the arc surface of the sliding rod has a spring, and the two ends of the spring are fixedly connected to the pull plate and the L-shaped plate, respectively.

[0009] The effect achieved by the above components is that, under the action of the spring, the sliding rod is automatically sprung into the adjustment slot of the adjustment plate, thus improving the practicality of the device.

[0010] Preferably, the arc surface of the sliding rod is provided with a limiting groove, and a limiting rod is slidably inserted into the L-shaped plate, the size of the limiting rod being adapted to the size of the limiting groove of the sliding rod.

[0011] The effect achieved by the above components is as follows: by setting the limiting rod, the sliding rod after stretching is limited, which makes it easier for the staff to adjust the height of the adjusting plate to adapt to the sealing support of the mining pipeline at different heights, thus improving the practicality of the device.

[0012] Preferably, one end of the limiting rod is fixedly connected to a soft rope, and one end of the soft rope is fixedly connected to the L-shaped plate.

[0013] The effect achieved by the above components is to prevent the limit rod from being lost by setting up a soft rope, thereby improving the practicality of the device.

[0014] Preferably, one end of the threaded rod is fixedly connected to a handle, and the surface of the handle is provided with anti-slip protrusions.

[0015] The effect achieved by the above-mentioned components is that by setting handles, it is easier for workers to operate the threaded rod, which facilitates the plugging of leaks in the mining pipeline and improves the practicality of the device.

[0016] Preferably, two sliding rods are slidably inserted into both the first and second arc-shaped plates, and one end of each sliding rod is fixedly connected to the clamping plate.

[0017] The effect achieved by the above components is that by setting the sliding rod, the clamping plate is guided, thus improving the practicality of the device.

[0018] Preferably, the surface of the sealing pad is coated with an adhesive used to seal the mining pipe.

[0019] The effect achieved by the above-mentioned components is that by applying adhesive to the sealing gasket, the mining pipeline can be repaired, thus extending the service life of the mining pipeline.

[0020] In this invention, by setting a buffer rod and a base plate under the fixed plate, the impact force on the device during the leak-sealing process can be effectively buffered, improving stability. The support plate and the adjustable sliding plate cooperate to facilitate the adjustment of the position of the first arc plate according to pipes of different diameters, enhancing the applicability of the device. The first arc plate and the rotatably connected second arc plate are fixed by bolts, which facilitates quick opening and closing to adapt to different operating scenarios. The setting of the threaded rod, clamping plate and sealing gasket can flexibly adjust the clamping force and sealing effect on the pipe, ensuring good leak-sealing performance.

[0026] Reference Figure 1-4As shown, this utility model provides a technical solution: a leak-sealing device for oilfield energy extraction pipelines, including a fixed plate 1, four buffer rods 2 fixedly installed on the lower surface of the fixed plate 1, a base plate 3 fixedly connected to one end of the four buffer rods 2, a support plate 4 fixedly connected to the surface of the fixed plate 1, an adjusting plate 5 slidingly connected inside the support plate 4, a first arc-shaped plate 6 fixedly connected to the surface of the adjusting plate 5, a second arc-shaped plate 7 rotatably connected to the first arc-shaped plate 6, a bolt 8 threadedly inserted into the second arc-shaped plate 7, two threaded rods 9 threadedly inserted into the arc surfaces of both the first arc-shaped plate 6 and the second arc-shaped plate 7, a clamping plate 10 rotatably connected to one end of the threaded rod 9, and a sealing gasket 11 fixedly connected to one side of the clamping plate 10. An L-shaped plate 12 is fixedly connected to the side wall of the support plate 4. A sliding rod 13 is slidably inserted into the L-shaped plate 12. Several adjustment grooves are opened on the surface of the adjustment plate 5. A pull plate 14 is fixedly connected to one end of the sliding rod 13. The size of the sliding rod 13 is adapted to the size of the adjustment groove of the adjustment plate 5. By setting a buffer rod 2 and a bottom plate 3 under the fixed plate 1, the impact force on the device during the leak sealing process can be effectively buffered, improving stability. The support plate 4 and the slidably adjustable adjustment plate 5 cooperate to facilitate the adjustment of the position of the first arc plate 6 according to the pipe diameter, enhancing the applicability of the device. The first arc plate 6 and the second arc plate 7, which is rotatably connected, are fixed by bolts 8, which facilitates quick opening and closing to adapt to different operating scenarios.The threaded rod 9, clamping plate 10, and sealing gasket 11 allow for flexible adjustment of the clamping force and sealing effect on the pipeline, ensuring good leak-stopping performance. A spring 15 is located on the arc surface of the sliding rod 13, with both ends of the spring 15 fixedly connected to the pull plate 14 and the L-shaped plate 12, respectively. Under the force of the spring 15, the sliding rod 13 automatically springs into the adjusting groove of the adjusting plate 5, improving the practicality of the device. A limiting groove is provided on the arc surface of the sliding rod 13, and a limiting rod 16 is slidably inserted into the L-shaped plate 12. The size of the limiting rod 16 matches the size of the limiting groove of the sliding rod 13. By setting the limiting rod 16, the stretched sliding rod 13 is limited, facilitating the adjustment of the height of the adjusting plate 5 by the operator to adapt to different heights for pipeline leak-stopping support, thus improving the practicality of the device. A soft rope 17 is fixedly connected to one end of the limiting rod 16. One end of the soft rope 17 is fixedly connected to the L-shaped plate 12. The soft rope 17 prevents the limit rod 16 from being lost, improving the practicality of the device. One end of the threaded rod 9 is fixedly connected to a handle 19, the surface of which has anti-slip protrusions. The handle 19 facilitates operation of the threaded rod 9, making it easier to plug leaks in the mining pipeline and improving the practicality of the device. Two sliding rods 18 are slidably inserted into both the first arc-shaped plate 6 and the second arc-shaped plate 7. One end of the sliding rod 18 is fixedly connected to the clamping plate 10. The sliding rods 18 guide the clamping plate 10, improving the practicality of the device. The surface of the sealing pad 11 is coated with adhesive for sealing the mining pipeline. The adhesive on the sealing pad 11 repairs the mining pipeline, extending its service life.

[0027] Working principle: When facing a pipeline leak, first move the device to the leak location. Install the base plate 3 on the ground. The buffer rod 2 under the fixed plate 1 and the base plate 3 can buffer the impact force on the device during placement and leak sealing, ensuring overall stability. The operator can adjust the position of the first arc plate 6 according to the pipe diameter to fit the pipe. The first arc plate 6 and the rotatably connected second arc plate 7 are fixed by bolts 8, which can be quickly opened and closed, facilitating the installation of the device on the pipe. After installation, turn the handle 19 to drive the threaded rod 9 to rotate. The threaded rod 9 pushes the clamping plate 10 to move along the slide rod 18, adjusting the clamping force on the pipe. At the same time, it makes the sealing gasket 11 fit tightly against the leak in the pipe, cooperating with the surface of the sealing gasket 11. The applied adhesive effectively seals the pipeline. When the device height needs to be adjusted to accommodate pipelines at different heights, pulling the pull plate 14 causes the sliding rod 13 to overcome the force of the spring 15 and be pulled out of the adjustment groove of the adjustment plate 5. This pushes the limiting rod 16 to slide within the L-shaped plate 12 until the limiting rod 16 slides into the limiting groove of the sliding rod 13, thus limiting the sliding rod 13. The adjustment plate 5 can then slide within the support plate 4. After adjusting to the appropriate position, pulling the limiting rod 16 releases the limiting rod 16 from the sliding rod 13. Under the action of the spring 15, the sliding rod 13 automatically springs into the corresponding adjustment groove, fixing the position of the adjustment plate 5. This allows for convenient adjustment of the height of the adjustment plate 5, completing the leak-sealing support work for pipelines at different heights.
