Description

Technical Field

[0001] The invention belongs to the technical field of emergency repair of gas pipelines, and in particular relates to a quick plugging rod for a gas pipeline and an operating method thereof. Background Art

[0002] In the emergency repair of gas pipelines, especially when it comes to small-diameter auxiliary pipelines on gas pipelines (such as vent pipes, drain pipes, bypass pipes, etc.), traditional plugging methods face many challenges. These auxiliary pipelines are usually located in key positions of the gas pipeline system due to their small diameters. Once damaged or broken, gas will leak out quickly, which will not only seriously threaten the safety of on-site workers, but also may cause environmental pollution and greater safety accidents.

[0003] Traditional plugging methods often require on-site production of plugging materials, which is not only time-consuming but also difficult to ensure the plugging effect. During the emergency repair process, 2-3 operators are usually required to wear respiratory protection equipment to operate, which not only increases the difficulty of the operation but also limits the efficiency of the emergency repair. More importantly, due to the uncertainty of the production of plugging materials and the plugging process, the success and time of the plugging are difficult to control, resulting in continuous gas leakage, which is extremely risky. Summary of the invention

[0004] The purpose of the present invention is to provide a gas pipeline rapid plugging rod and an operating method thereof in view of the problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, the invention adopts the following technical scheme: a gas pipeline quick sealing rod, including a rod body, a sealing air bag is installed on the periphery of the rod body, a cavity structure is provided in the rod body, the bottom wall of the cavity structure is provided with an air flow channel, the side wall of the air flow channel is provided with a plurality of air holes connected with the sealing air bag, an air supply part is installed in the cavity structure, a connecting seat is installed on the upper end of the rod body, a degassing part is provided on the connecting seat, an auxiliary part used in conjunction with the air supply part is provided on the connecting seat, and an end cover for covering the auxiliary part is provided on the upper end of the connecting seat.

[0006] By adopting the above technical scheme, the core of this patent is to propose a gas pipeline rapid sealing rod, whose structure includes a rod body, a sealing airbag, a cavity structure, an air flow channel, an air hole, an air supply part, a connecting seat, an air release part, an auxiliary part and an end cover. This design enables the sealing rod to quickly and effectively seal the gas pipeline, especially in an emergency situation, and can respond quickly to reduce the risk of gas leakage. The use of the sealing airbag ensures the sealing and stability of the plugging, and the design of the cavity structure, air flow channel and air hole ensures that the gas can smoothly enter the sealing airbag and achieve rapid expansion.

[0007] Optionally, the lower end of the rod body is "pointed", and the outer periphery of the rod body is provided with anti-slip grooves.

[0008] By adopting the above technical solution, the lower end of the rod body is designed to be pointed, which is convenient for inserting the blocking rod into the gas pipeline, especially when the pipeline diameter is small or the position is difficult to reach. This design greatly improves the convenience of using the blocking rod. At the same time, the anti-slip pattern design on the periphery of the rod body increases the friction between the rod body and the hand, preventing slipping during use and ensuring the safety of operation.

[0009] Optionally, the gas supply component includes a high-pressure air bag or a high-pressure gas cylinder.

[0010] By adopting the above technical solution, the gas supply parts select high-pressure airbags or high-pressure gas cylinders. Both gas supply methods have high reliability and stability. The high-pressure airbags are light and easy to carry, suitable for quick response; and the high-pressure gas cylinders can provide a more lasting gas supply to meet the needs of long-term blocking. This design enables the blocking rod to maintain excellent performance in different application scenarios.

[0011] Optionally, the connecting seat is threadedly connected to the rod body, and a retaining plate for limiting the air supply component is respectively installed in the connecting seat and the cavity structure, and a pair of the retaining plates are respectively provided with a plurality of through holes on their surfaces.

[0012] By adopting the above technical solution, the connecting seat is threadedly connected to the rod body, which is convenient for disassembly and replacement of the air supply parts, while also ensuring the stability of the connection. The design of the positioning plate effectively limits the air supply parts to prevent them from moving or falling off during the sealing process, thereby ensuring the normal operation of the sealing rod. The setting of the through hole ensures that the gas can pass smoothly into the sealing airbag.

[0013] Optionally, the air venting member includes a movable groove opened at the lower end of the connecting seat, a mounting seat is provided on the inner side of the movable groove, a sealing gasket is provided on the outer side of the mounting seat, a connecting column penetrating through and extending to the outer side of the movable groove is installed at the upper end of the mounting seat, a connecting ring is provided at the upper end of the connecting column, a pull rope is tied to the connecting ring, a reset spring is installed between the mounting seat and the movable groove, and an exhaust channel is opened on the side wall of the movable groove.

[0014] By adopting the above technical solution and the design of the deflation part, when the blockage needs to be released, it is only necessary to pull the pull rope to quickly open the exhaust channel, so that the gas in the blocking airbag can flow back and be discharged, thereby achieving the contraction and detachment of the blocking airbag. This design greatly improves the convenience and flexibility of the operation of the blocking rod, while also reducing the difficulty and risk of operation.

[0015] Optionally, the auxiliary part includes a mounting hole opened on the surface of the connecting seat, a movable column is provided on the inner side of the mounting hole, a fixing plate is installed at the lower end of the movable column, a pair of ejector pins are installed at the lower end of the fixing plate, a pressing seat is installed at the upper end of the movable column, and a connecting spring is installed between the pressing seat and the connecting seat.

[0016] By adopting the above technical solution, when the air supply part is a high-pressure airbag, the design of the auxiliary part makes it possible to puncture the high-pressure airbag through the ejector pin by simply pressing down the pressing seat, releasing the gas into the sealing airbag. This design simplifies the operation process, improves the sealing efficiency, and also ensures the safety of the operation.

[0017] Optionally, the auxiliary component includes a threaded hole opened on the surface of the connecting seat, a threaded column is connected in the threaded hole, a pressure plate is installed at the lower end of the threaded column, and a rotating seat is installed at the upper end of the threaded column.

[0018] By adopting the above technical solution, when the gas supply part is a high-pressure gas cylinder, the design of the auxiliary part makes it possible to squeeze and deflate the high-pressure gas cylinder through the pressure plate only by rotating the rotating seat. This design also simplifies the operating process, improves the sealing efficiency, and also ensures the safety and stability of the operation.

[0019] Optionally, the end cover is threadedly connected to the connecting seat.

[0020] By adopting the above technical solution, the end cover is threadedly connected to the connecting seat, which is easy to disassemble and install, while also ensuring the covering and protection of the auxiliary parts by the end cover. This design allows the sealing rod to remain clean and intact when not in use, extending its service life.

[0021] Optionally, a method for operating a gas pipeline rapid plugging rod comprises the following steps:

[0022] Unscrew the end cover from the connecting seat, and insert the lower end of the plugging rod into the gas pipeline to be plugged;

[0023] When the high-pressure airbag is used as the air supply component, the push seat is pressed downward so that the ejector pin punctures the high-pressure airbag, and the gas in the high-pressure airbag enters the blocking airbag through the airflow channel and the air hole;

[0024] When the high-pressure gas cylinder is used as a gas supply component, the pressing plate is moved downward by the rotation of the rotating seat to squeeze and deflate the high-pressure gas cylinder, and the deflated gas enters the blocking airbag through the air flow channel and the air hole;

[0025] The expansion of the blocking airbag closely contacts the inner wall of the gas pipeline, thus achieving rapid blocking;

[0026] When the blockage needs to be released, the pull rope on the degassing member is pulled, and the pull rope drives the mounting seat to move upward, opening the exhaust channel, and the gas in the blocking airbag will flow back and be discharged through the airflow channel and the air hole, and the blocking airbag will gradually shrink;

[0027] After the blocking airbag is completely contracted and separated from the inner wall of the gas pipeline, the rod body is pulled out of the gas pipeline by the pull rope.

[0028] By adopting the above technical scheme, the operation method elaborates on the steps of using the blocking rod, including unscrewing the end cap, inserting the rod body, pressing down the pressing seat or rotating the rotating seat to release the gas, the blocking airbag expanding to fit tightly against the inner wall of the pipe to achieve blocking, pulling the pull rope to release the blockage and pulling out the rod body. This operation method is simple and clear, easy to master, and greatly improves the efficiency and success rate of using the blocking rod. At the same time, this operation method also fully considers safety and convenience, and reduces the difficulty and risk of operation.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention uses a high-pressure airbag or a high-pressure gas cylinder as a gas supply part, combined with the rapid expansion characteristics of the blocking airbag, to achieve the blocking of the auxiliary pipelines of the gas pipeline in a very short time, greatly improving the efficiency of emergency repairs; the blocking airbag can be close to the inner wall of the gas pipeline to form an effective seal, avoiding the risk of gas leakage, ensuring the safety of on-site workers, and also reducing the possibility of environmental pollution.

[0031] 2. The plugging rod of the present invention is reasonably designed and easy to operate, and can be mastered without complicated training and skills, thus reducing the difficulty of emergency repair work.

[0032] 3. The plugging rod is suitable for gas pipeline ancillary pipes of different diameters. It has strong adaptability and flexibility and can meet the needs of various emergency repair scenarios.

[0033] 4. The blockage can be easily released by pulling the drawstring on the venting piece. The blocking airbag shrinks and detaches from the inner wall of the pipe, making it easy to clean and handle without interfering with the normal operation of the pipe. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0044] like Figure 1—6, the specific scheme of the first embodiment is as follows: a gas pipeline rapid plugging rod, comprising a rod body 1, the rod body 1 is used as the main structure of the plugging rod, and is used to be inserted into the gas pipeline. The lower end of the rod body 1 is "pointed", and the outer periphery of the rod body 1 is provided with anti-slip grooves 101. The lower end of the rod body 1 is designed to be "pointed" to facilitate easy insertion into the pipeline. The anti-slip grooves 101 on the outer periphery increase the friction when holding, prevent slipping, and ensure safe operation. The rod body 1 can be made of metal material or plastic material. The outer periphery of the rod body 1 is installed with a plugging airbag 2. The plugging airbag 2 expands after being inflated and is close to the inner wall of the gas pipeline to achieve rapid plugging, which can effectively prevent gas leakage and ensure the safety of personnel and the environment;

[0045] A cavity structure 3 is provided in the rod body 1, and the cavity structure 3 provides installation space for the air supply part 6 and other internal components, optimizing the internal layout, making the sealing rod structure compact and easy to carry and use. The bottom wall of the cavity structure 3 is provided with an air flow channel 4, and the air flow channel 4 can transfer the gas in the air supply part 6 to the sealing airbag 2, ensuring that the gas can smoothly and quickly enter the sealing airbag 2 to achieve rapid blocking. The side wall of the air flow channel 4 is provided with a plurality of air holes 5 connected to the sealing airbag 2, and the air holes 5 can evenly distribute the gas in the air flow channel 4 to the sealing airbag 2, ensuring that the sealing airbag 2 can expand evenly when inflated, close to the inner wall of the pipeline, and improve the blocking effect.

[0046] The cavity structure 3 is provided with an air supply member 6, which is used to store and provide gas for inflating and plugging the airbag 2. The air supply member 6 is a high-pressure airbag 61, which stores compressed gas. The high-pressure airbag 61 is light and easy to carry, and suitable for quick response. A connecting seat 7 is provided on the upper end of the rod body 1, and the connecting seat 7 is threadedly connected to the rod body 1. The threaded connection design allows the cavity structure 3 to be opened conveniently, so that the air supply member 6 in the cavity structure 3 can be replaced. The replacement of the air supply member 6 allows the plugging rod to be used multiple times. The connecting seat 7 and the cavity structure 3 are respectively provided with a positioning plate 701 for limiting the air supply member 6. The positioning plate 701 can limit the air supply member 6 to prevent it from moving or falling off during the plugging process, thereby improving the reliability and stability of the plugging rod and ensuring the plugging effect. A pair of through holes 702 are respectively provided on the surfaces of the positioning plates 701, and the through holes 702 can provide channels for the circulation of gas.

[0047] The connecting seat 7 is provided with a deflation member 8, and the deflation member 8 includes a movable groove 81 opened at the lower end of the connecting seat 7, a mounting seat 82 is provided on the inner side of the movable groove 81, and a sealing gasket 83 is provided on the outer side of the mounting seat 82. The setting of the sealing gasket 83 can prevent gas leakage, and the upper end of the mounting seat 82 is provided with a connecting column 84 that penetrates and extends to the outer side of the movable groove 81, and the upper end of the connecting column 84 is provided with a connecting ring 85, and a pull rope 86 is tied to the connecting ring 85. The pull rope 86 can drive the mounting seat 82 to move up and open the exhaust channel 88 for exhaust. At the same time, the pull rope 86 can also push the deflated rod body 1 Pull out, a reset spring 87 is installed between the mounting seat 82 and the movable groove 81. When the air pressure in the cavity structure 3 is less than the elastic force of the reset spring 87, there is no need to set a limiting structure on the connecting column 84. When the air pressure in the cavity structure 3 is greater than the pressure of the reset spring 87, the outer periphery of the connecting column 84 is provided with a thread. Before deflation, it is necessary to release the limit of the thread, and then pull the pull rope 86 to deflate. The side wall of the movable groove 81 is provided with an exhaust channel 88. By pulling the pull rope 86, the exhaust channel 88 can be opened to allow the gas in the blocking airbag 2 to flow back and be discharged, thereby realizing the contraction and detachment of the blocking airbag 2, which is convenient for subsequent operations.

[0048] The connecting seat 7 is provided with an auxiliary member 9 used in conjunction with the air supply member 6, and the auxiliary member 9 includes a mounting hole 91 opened on the surface of the connecting seat 7, a sealing ring 911 is provided on the inner side of the mounting hole 91, and a movable column 92 is provided on the inner side of the mounting hole 91, and the movable column 92 is located on the inner periphery of a pair of the sealing rings 911, and a fixing plate 93 is installed at the lower end of the movable column 92, and a pair of ejector pins 94 are installed at the lower end of the fixing plate 93, and a pressing seat is installed at the upper end of the movable column 92. 95, a connecting spring 96 is installed between the pressing seat 95 and the connecting seat 7. By pressing the pressing seat 95, the ejector pin 94 punctures the high-pressure airbag 61 to release the gas, which simplifies the operation process and improves the blocking efficiency. The upper end of the connecting seat 7 is provided with an end cover 10 for covering the auxiliary part 9. The end cover 10 is threadedly connected to the connecting seat 7. The end cover 10 can cover and protect the auxiliary part 9 to prevent the auxiliary part 9 from being damaged during transportation or use, thereby extending the service life of the blocking rod;

[0049] The design of the pull rope 86 allows the plugging rod to deflate the gas supply member 6 by triggering the auxiliary member 9 after the end cover 10 is opened. During the deflation process, the plugging rod can be inserted into the gas pipeline, and the plugging airbag 2 expands and blocks the place that needs to be blocked. When inserted, one end of the pull rope 86 is left outside to facilitate the subsequent deflation and recovery of the plugging rod. The design of the pull rope 86 also gives the plugging rod higher flexibility. Whether in a narrow pipeline space or in an emergency, the operator can quickly complete the plugging and recovery operations by pulling the pull rope 86;

[0050] During the plugging process, the plugging rod does not need to rely on external equipment for gas supply. This feature greatly enhances its ability to work independently and the speed of emergency response. Through the high-pressure airbag 61 carried by itself, the plugging rod can quickly and stably provide sufficient gas for the plugging airbag 2 to ensure that it can cling to the inner wall of the gas pipeline to form an effective plug. The high-pressure airbag 61 is used as a gas supply component, and its design fully considers portability and durability. It can not only store enough gas to meet the plugging needs, but also has the characteristics of being light and easy to carry, so that the plugging rod can be quickly put into use in an emergency and can be used in It maintains stable performance in various harsh environments. During the plugging operation, the operator only needs to simply trigger the auxiliary part 9, and the gas in the high-pressure airbag 61 will quickly enter the plugging airbag 2 through the airflow channel 4 and a plurality of air holes 5, causing it to expand rapidly and fit tightly against the inner wall of the pipe. In this process, no external equipment is required to assist, which greatly simplifies the operation process and improves the plugging efficiency. After completing the plugging task, the plugging rod can also be quickly deflated and recovered by pulling the pull rope 86. This design not only facilitates subsequent operations, but also reduces the workload of operators and improves overall work efficiency.

[0051] like Figure 7 As shown, embodiment 2, on the basis of embodiment 1, embodiment 2 replaces the gas supply part 6 and the auxiliary part 9, the gas supply part 6 is a high-pressure gas cylinder 62, and the high-pressure gas cylinder 62 stores compressed gas, and the high-pressure gas cylinder 62 can provide a more lasting gas supply to meet the needs of long-term blocking, the auxiliary part 9 includes a threaded hole 97 opened on the surface of the connecting seat 7, a threaded column 98 is connected in the threaded hole 97, a pressure plate 99 is installed at the lower end of the threaded column 98, and a rotating seat 981 is installed at the upper end of the threaded column 98, by rotating the rotating seat 981, the pressure plate 99 is moved down, and the high-pressure gas cylinder 62 is squeezed and deflated, which also simplifies the operation process, but is suitable for the case where the high-pressure gas cylinder 62 is used as the gas supply part 6, and provides a more flexible blocking method.

[0052] A method for operating a gas pipeline rapid plugging rod, characterized in that the method comprises the following steps:

[0053] Before operation, ensure that the plugging rod and all accessories are intact and leak-free, and check whether the gas pressure of the high-pressure airbag 61 or the high-pressure gas cylinder 62 is sufficient to ensure the plugging effect;

[0054] Unscrew the end cover 10 from the connecting seat 7, and insert the lower end of the rod body 1 of the plugging rod into the gas pipeline to be plugged;

[0055] When the high-pressure airbag 61 is used as the air supply member 6, the push pin 94 punctures the high-pressure airbag 61 by pressing down the pressing seat 95, and the gas in the high-pressure airbag 61 enters the blocking airbag 2 through the air flow channel 4 and the air hole 5;

[0056] When the high-pressure gas cylinder 62 is used as the gas supply member 6, the pressing plate 99 moves downward by the rotation of the rotating seat 981 to squeeze and deflate the high-pressure gas cylinder 62, and the deflated gas enters the blocking airbag 2 through the air flow channel 4 and the air hole 5;

[0057] The expansion of the plugging airbag 2 is close to the inner wall of the gas pipeline to achieve rapid plugging. Observe the expansion of the plugging airbag 2 to ensure that it is close to the inner wall of the gas pipeline and there is no leakage. If leakage is found, stop the operation immediately and check the cause.

[0058] Install a control valve at the gas pipeline blockage;

[0059] When the blockage needs to be released, the control valve is opened, and the pull rope 86 on the degassing member 8 is pulled, and the pull rope 86 drives the connecting column 84 and the mounting seat 82 to move upward in the movable groove 81, thereby opening the exhaust channel 88. At this time, the gas in the blocking airbag 2 will flow back and be discharged through the airflow channel 4 and the air hole 5, so that the blocking airbag 2 gradually shrinks;

[0060] After the blocking airbag 2 is completely contracted and separated from the inner wall of the gas pipeline, the rod body 1 is pulled out of the gas pipeline by the pull rope 86 and the control valve is closed.
