Description

Technical Field

[0001] This utility model relates to the field of oil and gas pipeline leak sealing technology, specifically a leak sealing device for primary oil and gas leakage in power plant electrical systems. Background Technology

[0002] The electrical system of a power plant mainly consists of generators, transformers, switchgear, and cables. It is mainly used to convert the energy of fuels such as coal, oil, and natural gas into electrical energy to supply users. Due to the external environment of wind and sun, as well as the long-term use of pipelines, the operating equipment is prone to aging of seals and damage to pipelines, which can easily lead to oil and gas leakage. If the leaks are not plugged in time, it will affect the use and pose certain safety hazards.

[0003] For example, a leak sealing device for primary oil and gas leakage in a thermal power plant, as described in application number CN202420852404.2, includes a sealing component and a support component threaded onto the upper middle part of the sealing component. Clamping and fixing components are fixedly installed on both sides of the lower end of the support component. The operator moves the vertical support blocks at both ends of one side of the support component to engage the main clamping plate at both ends of one side of the pipeline. Then, the auxiliary clamping plate is connected to the main clamping plate from the other ends of the pipeline. This causes the square blocks at both ends of one side of the main clamping plate to engage with the triangular locking blocks, which in turn engage with the corresponding locking blocks. When it is necessary to adjust the tightness of the connection between the main clamping plate and the auxiliary clamping plate, the handle is pulled to move the extension block to one side, which in turn moves the corresponding locking block. After the triangular locking block loses its corresponding locking block's limit, the square blocks can be readjusted in height. This device is convenient to use.

[0004] In the aforementioned patent, a clamp-type structure is used to fix and seal the pipeline. However, due to the difficulty in accurately locating the leakage point, it is very easy for the sealing structure to not correspond to the leakage point during the initial installation. In this case, if the sealing position needs to be adjusted, the fastening bolts of the clamp must be completely loosened, the clamp must be removed, and the position repositioned and installed. The whole process requires repeated disassembly, calibration, and fixing, which is cumbersome and not only consumes a lot of time but also increases the workload of the operators.

[0005] Furthermore, during repeated disassembly and adjustment, the sealing performance of the clamps and pipes is easily affected, which may lead to a decrease in the stability of the device. In fact, improper operation during the adjustment process may even cause damage to the pipe surface or exacerbate leakage. At the same time, for scenarios such as power plants where the safety requirements for equipment operation are extremely high, this cumbersome adjustment process will prolong the leakage handling time and increase the risk of secondary disasters such as fires and equipment damage caused by oil and gas leaks, failing to meet the actual needs for rapid and efficient leak sealing.

[0006] Therefore, we propose a device for sealing primary oil and gas leaks in power plants to address the aforementioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a device for sealing primary oil and gas leaks in power plants, in order to solve the problems mentioned in the background art.

They cannot meet the actual needs of rapid and efficient leak sealing.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a power plant electrical primary oil and gas leakage sealing device, comprising a pipeline, wherein a retaining ring one and a retaining ring two are clamped around the outer ring of the pipeline, a screw is fixed on the retaining ring one, the retaining ring one is inserted into the screw, a nut is threaded onto the screw, two sets of retaining ring one and retaining ring two are symmetrically arranged, a connecting post is fixed on the two retaining ring two, a connecting block is fixed on both sides of the connecting post, a guide rod is fixed on the connecting block, a slider one slides around the outer ring of the guide rod, a mounting seat is fixed on one end of the slider one, a moving component is installed on the connecting post, a fixing rod is fixed on the mounting seat, an arc frame is slidably sleeved around the outer ring of the fixing rod, an adjusting component is installed on the mounting seat, an electric push rod is fixed on the bottom surface of the arc frame, and a sealing plate is fixed on the bottom surface of the electric push rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

[0022] 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.

[0023] Example 1: Please refer to Figure 1 - Figure 4 A leak-sealing device for oil and gas leakage in the primary electrical system of a power plant includes a pipe 1, which is a metal pipe 1 that transports oil and gas in the primary electrical system of the power plant and is the target of the leak-sealing device. A retaining ring 2 and a retaining ring 4 are clamped to the outer circumference of the pipe 1. A screw 3 is fixed to the retaining ring 2, and the retaining ring 2 is inserted into the screw 3. A nut 5 is threaded onto the screw 3. Two sets of retaining rings 2 and 4 are symmetrically arranged. The retaining rings 2 and 4 are made of high-strength alloy material, and their inner sides have arc-shaped grooves 131 that fit the outer circumference of the pipe 1. Anti-slip rubber pads can be attached to the inner wall of the grooves 131 to enhance friction with the pipe 1 and prevent the retaining rings from sliding on the pipe 1. The two sets of retaining rings 2 and 4 are symmetrically arranged and can be spliced ​​together to completely enclose the outer circumference of the pipe 1. The splicing points of each set of retaining rings are detachably connected with bolts for easy installation and disassembly. The second retaining ring 4 has a reserved hole. One end of the screw 3 is welded and fixed to the first retaining ring 2, and the other end passes through the reserved hole on the second retaining ring 4. The retaining ring 2 and the second retaining ring 4 are fastened by tightening the nut 5. The nut 5 is an anti-loosening nut, which can effectively prevent loosening in the equipment vibration environment and ensure the clamping stability of the retaining ring on the pipe 1.

[0024] Two retaining rings 4 are fixed with connecting posts 6. Connecting blocks 7 are fixed on both sides of the connecting posts 6. Guide rods 8 are fixed on the connecting blocks 7. Sliding sliders 9 slide on the outer ring of the guide rods 8. Mounting bases 10 are fixed on the end of the sliding sliders 9. Moving components 91 are installed on the connecting posts 6. Fixing rods 11 are fixed on the mounting bases 10. Arc-shaped frames 12 slide on the outer ring of the fixing rods 11. Adjusting components 13 are installed on the mounting bases 10. Electric push rods 14 are fixed on the bottom surface of the arc-shaped frames 12. Sealing plates 15 are fixed on the bottom surface of the electric push rods 14. Sealing plates 15 are made of corrosion-resistant and high-temperature resistant sealing materials (such as rubber and silicone composite materials). The specific material needs to be selected according to the actual situation. Its shape can be adapted to the shape of the leakage location of the pipe 1 to ensure the sealing effect.

[0025] The movable component 91 includes support blocks 911 fixedly connected to both sides of the connecting column 6. There are two support blocks 911 symmetrically arranged about the mounting base 10. A lead screw 912 is rotatably connected between the two support blocks 911. A rocker arm 913 is fixed to the end of the lead screw 912. A second slider 914 is threaded on the lead screw 912. The second slider 914 is fixedly connected to the mounting base 10. There are two mounting bases 10 symmetrically arranged. Both mounting bases 10 are fixedly connected to the first slider 914 and the second slider 914.

[0026] The adjusting assembly 13 includes a groove 131 formed on one of the mounting seats 10, a rotating shaft 132 rotatably connected within the groove 131, a worm gear 133 fixedly sleeved on the outer ring of the rotating shaft 132, a rotating rod 135 rotatably mounted between the two mounting seats 10, a worm wheel 134 fixedly sleeved on the outer ring of the rotating rod 135, the worm gear 133 and the worm wheel 134 meshing with each other, having a self-locking function to ensure stable position after adjustment, a gear 136 fixedly sleeved on the outer ring of the rotating rod 135, multiple toothed grooves 137 distributed in an arc-shaped array on the arc-shaped frame 12, the gear 136 meshing with the toothed grooves 137, an arc-shaped groove 121 formed within the arc-shaped frame 12, the arc-shaped frame 12 slidably connected to the fixed rod 11 through the arc-shaped groove 121. The fixed rod 11 guides and limits the movement of the arc-shaped frame 12.

[0027] In this embodiment: First, snap ring 2 and snap ring 4 are symmetrically snapped onto the outer ring near the leakage location of pipe 1. A screw 3 is then threaded through the pre-drilled holes of snap ring 2 and snap ring 4, and the nut 5 is tightened to secure the connection, thus stably fixing the entire device to pipe 1. The anti-slip rubber pad on the inner side of the snap ring significantly enhances the friction with the surface of pipe 1, effectively preventing the device from shifting during pipe 1 vibration or operation.

[0028] Based on the axial coordinate of the leakage location, the operator rotates the rocker arm 913, which drives the lead screw 912 to rotate smoothly between the two support blocks 911. Since the second slider 914 is threadedly connected to the lead screw 912, and the second slider 914 is rigidly fixed to the mounting base 10, while the mounting base 10 forms a sliding engagement with the guide rod 8 through the first slider 9, the rotational motion of the lead screw 912 is precisely converted into the axial linear motion of the second slider 914, thereby driving the mounting base 10 to move smoothly along the axial direction of the guide rod 8, and precisely adjusting the sealing plate 15 to the position corresponding to the axial direction of the leakage location.

[0029] Subsequently, the operator rotates the crank handle of the adjusting assembly 13's shaft 132. The shaft 132 drives the worm gear 133 to rotate synchronously. The worm gear 133 and the worm wheel 134 are driven by tooth surface meshing, driving the rotating rod 135 to rotate. The gear 136 on the outer ring of the rotating rod 135 rotates accordingly. The gear 136 meshes with the arc-shaped tooth groove 137 on the arc-shaped frame 12, causing the arc-shaped frame 12 to slide along the fixed rod 11 through the arc-shaped groove 121, realizing the fine adjustment of the angle of the arc-shaped frame 12, and finally adjusting the sealing plate 15 to an angle that perfectly matches the curvature of the leaking position of the pipe 1.

[0030] After completing the position and angle calibration, the electric actuator 14 is activated. The output end of the electric actuator 14 extends axially, pushing the sealing plate 15 closer to the leak location in pipe 1 until the sealing plate 15 is tightly fitted to the surface of the leak point. Utilizing the elastic sealing performance of the sealing plate 15, the oil and gas leakage path can be quickly blocked, preventing further leakage of the medium.

[0031] If it is necessary to adjust the sealing position or remove the device, the electric actuator 14 can be operated in reverse to detach the sealing plate 15 from the surface of the pipeline 1. The angle of the arc frame 12 can be adjusted in reverse by adjusting the component 13, and the axial position of the mounting base 10 can be changed by using the moving component 91. Alternatively, the nut 5 can be loosened to remove the retaining ring 2 and retaining ring 4, enabling flexible adjustment and reuse of the device. The entire device, through the precise transmission of the mechanical structure and the coordinated operation of the electric actuator, can achieve rapid and accurate sealing of oil and gas leaks in the pipeline 1, significantly improving the efficiency and reliability of the leak sealing operation.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
