Description

Technical Field

[0001] This utility model relates to the technical field of pipeline repair devices, specifically a rapid maintenance and repair device for high-pressure oil and gas pipelines. Background Technology

[0002] A pipeline is a device consisting of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations. Pipelines are classified by material into metallic and non-metallic pipelines. However, regardless of the material, pipelines inevitably suffer damage over time, leading to leaks of the transported medium. Timely repair is necessary. Existing pipeline repair equipment requires stopping the transport of the medium within the pipeline and treating the damaged area, resulting in a complex and costly repair process.

[0003] Currently, there are no successful rapid repair cases for high-pressure pipelines in China. For low-pressure pipeline leaks, sealing is generally done by injecting epoxy resin through a clamp, which involves making a hole in the clamp surface and then injecting epoxy resin through an injection pump. This results in low pipeline repair efficiency. Therefore, we have proposed a rapid repair and maintenance device for high-pressure oil and gas pipelines to solve the above-mentioned problems.

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.

[0024] like Figure 1-3 As shown:

[0025] A rapid maintenance and repair device for high-pressure oil and gas pipelines includes a first housing 101 and a second housing 102 installed on the pipeline.

[0026] A locking element 2 is installed between the first housing 101 and the second housing 102, and the locking element 2 is used to connect and lock the first housing 101 and the second housing 102.

[0027] The locking component 2 includes a first strip plate 201 fixed to the edge surface of the first housing 101 and symmetrically arranged, and a second strip plate 202 fixed to the edge surface of the second housing 102 and symmetrically arranged. A socket 203 is fixed on one side of the first strip plate 201. A locking plate 205 slides inside the socket 203. Multiple sets of springs 204 are fixed between the locking plate 205 and the socket 203. A strip groove adapted to the socket 203 is opened on the upper surface of the second strip plate 202. The second strip plate 202 is also opened with an insertion hole 207 adapted to the locking plate 205. The insertion hole 207 is connected to the strip groove.

[0028] A sliding groove adapted to the card plate 205 is provided on one side of the socket 203, and the card plate 205 can slide in the sliding groove provided in the socket 203;

[0029] The inner wall of the first housing 101 is provided with a limiting groove, and a sealing seat 103 is provided in the limiting groove;

[0030] One side of the surface of the sealing seat 103 is provided with an arc-shaped structure, and a sealing ring 104 is fixedly installed on the arc-shaped surface of the sealing seat 103;

[0031] Bolts 106 are provided on the first housing 101;

[0032] A connecting seat 105 is fixedly installed on the upper surface of the first housing 101 through an opening mounting hole. The connecting seat 105 is threadedly connected to the bolt 106 through an opening threaded hole. The mounting hole on the upper surface of the first housing 101 is connected to the limiting groove.

[0033] In this implementation plan: When the high-pressure oil and gas pipeline rapid maintenance and repair device is in use, if the pipeline (not shown in the figure) is damaged and needs rapid repair;

[0034] First, the first housing 101 and the second housing 102 are aligned, and the locking member 2 is used to lock the first housing 101 and the second housing 102 in relative contact, so that the first housing 101 and the second housing 102 are stuck on the surface of the pipe.

[0035] When the first housing 101 and the second housing 102 are fitted together, they form an annular sleeve, and the annular sleeve is adapted to the outer diameter of the pipe.

[0036] When the locking member 2 connects and locks the first housing 101 and the second housing 102, the first strip plate 201 and the second strip plate 202 are aligned. During this process, the socket 203 is inserted into the slot in the second strip plate 202. At this time, the retaining plate 205 is pressed by the second strip plate 202, which completely compresses the retaining plate 205 into the sliding groove inside the socket 203, and simultaneously compresses the spring 204. The card plate 205 has an inclined surface design on one side, which has a certain guiding function. When the card plate 205 is squeezed, it can automatically compress the card plate 205 into the socket 203. When the socket 203 is fully inserted into the slot, the card plate 205 and the socket 207 correspond. At this time, the spring 204, which is in a compressed state, rebounds and drives the card plate 205 to move, so that the card plate 205 is partially inserted into the socket 207, thereby connecting and locking the first housing 101 and the second housing 102.

[0037] When the first housing 101 and the second housing 102 are clamped onto the pipe, the second housing 102 and the first housing 101 are located to the side of the pipe breakage location. After the first housing 101 and the second housing 102 are clamped together, the first housing 101 and the second housing 102 are then pushed laterally so that the second housing 102 and the first housing 101 are located at the pipe breakage location, and the sealing seat 103 corresponds to the breakage location.

[0038] This operation allows the first housing 101 and the second housing 102 to be pre-attached to the pipe. By moving the device laterally to the location of the pipe rupture, the problem of large pressure relief at the pipe rupture location, which makes it inconvenient to install the device at the location of the pipe rupture, is solved.

[0039] When the sealing seat 103 is at the location of the pipe breakage, the staff uses a wrench to tighten the bolt 106. The bolt 106 is threadedly connected to the connecting seat 105. As the bolt 106 moves down, it squeezes the sealing seat 103. One side of the sealing seat 103 is arc-shaped, and the arc-shaped surface can better fit the pipe surface.

[0040] By squeezing the sealing seat 103, the sealing seat 103 squeezes the sealing ring 104. The sealing ring 104 increases the sealing between the sealing seat 103 and the pipeline, thereby sealing the damaged part of the pipeline.

[0041] This solution can address the issue of rapid pipeline repair, significantly reduce emergency response time for pipeline leaks, improve emergency response efficiency, reduce direct and indirect economic losses caused by pipeline failure, ensure the safe operation of pipelines, and meet actual usage requirements.

[0042] It should be noted that multiple sets of connecting seats 105 can be flexibly installed according to the length of the sealing seat 103, and bolts 106 are installed on each connecting seat 105. The stability of the compression of the sealing seat 103 is increased by multiple sets of bolts 106.

[0043] Furthermore;

[0044] In an optional embodiment, the upper surface of the sealing seat 103 is fixed with multiple sets of limiting pins 107, and the surface of the first housing 101 is provided with sliding holes adapted to the limiting pins 107, so that the limiting pins 107 can slide within the sliding holes provided in the first housing 101.

[0045] In this embodiment, the sealing seat 103 is connected to the first housing 101 through multiple sets of limiting pins 107. The limiting pins 107 can limit the sealing seat 103, preventing it from falling off or being lost.

[0046] Furthermore;

[0047] In an optional embodiment, the connector 105 is provided with a cap 108 to shield and protect the bolt 106, and the cap 108 is interference-fitted into the top outer side of the connector 105.

[0048] In this embodiment, the cap 108 can protect the bolt 106, preventing the threads on the surface of the bolt 106 from getting mud on them, which would affect the rotation of the bolt 106. The cap 108 ensures the cleanliness of the bolt 106.

[0049] Furthermore;

[0050] In an optional embodiment, a screw rod 206 is threadedly connected to one side of the second strip plate 202 through a threaded hole, and a through hole corresponding to the threaded hole is provided on the socket 203, which is connected to the sliding groove.

[0051] In this embodiment: as follows Figure 3 As shown: One end of the second strip plate 202 is threadedly connected to a screw rod 206. By rotating the screw rod 206, one end of the screw rod 206 can pass through the through hole of the socket 203 to press the clamping plate 205, which can flexibly lock the clamping plate 205. When the first housing 101 and the second housing 102 are large in size, it is difficult to press the clamping plates 205 on both sides with both hands. With the setting of the screw rod 206, the clamping plate 205 on one side can be pressed first and temporarily locked by the screw rod 206. Then the clamping plate 205 on the other side can be pressed to install the first housing 101 and the second housing 102.

[0052] The working principle and usage process of this utility model: When this high-pressure oil and gas pipeline rapid maintenance and repair device is in use, when the pipeline (not shown in the figure) is damaged and needs rapid repair;

[0053] First, align the first housing 101 and the second housing 102, and simultaneously use the locking element 2 to lock the first housing 101 and the second housing 102 into contact with each other, securing them to the pipe surface. When the first housing 101 and the second housing 102 are secured to the pipe, their positions are adjacent to the pipe breakage location. After the first housing 101 and the second housing 102 are engaged, push them laterally until they are positioned at the pipe breakage location, with the sealing seat 103 corresponding to the breakage location. When the sealing seat 103 is aligned with the pipe breakage location, the worker... Using a wrench, bolt 106 is tightened, and bolt 106 is threadedly connected to connecting seat 105. As bolt 106 moves downward, it compresses sealing seat 103. One side of sealing seat 103 is arc-shaped, and this arc shape better fits the pipe surface. By compressing sealing seat 103, sealing seat 103 compresses sealing ring 104. The sealing ring 104 increases the sealing between sealing seat 103 and the pipe, thereby sealing the damaged area of ​​the pipe. This solution can solve the problem of rapid pipe repair, significantly reduce the emergency response time for pipe leaks, improve emergency response efficiency, reduce direct and indirect economic losses caused by pipe failure, ensure the safe operation of the pipeline, and meet actual usage needs.

[0054] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
