A rapid emergency sealing device for oil and gas pipeline leaks Technical Field

[0001] This utility model relates to the field of oil and gas pipeline technology, and in particular to a rapid emergency sealing device for oil and gas pipeline leaks. Background Technology

[0002] Oil and gas pipelines are important structures in oil and natural gas transportation lines and are crucial factors in ensuring the safe transport of oil or natural gas. During long-term use, oil and gas pipelines are often affected by factors such as pipeline pressure changes and external environmental factors, which often lead to local leaks at pipeline joints. Sealing devices are needed to reduce the occurrence of accidents. In the current technology, when a local leak occurs at a pipeline joint, a metal clamp is used to wrap the leak point and the sealing gasket is tightened by bolts. However, tightening multiple bolts wastes a lot of time, cannot quickly stop the leak, and the sealing effect is poor. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies that rely on bolts to tighten the sealing gasket, which wastes a lot of time, fails to quickly stop leaks, and has a poor sealing effect. Therefore, this invention proposes a rapid emergency sealing device for oil and gas pipeline leaks.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rapid emergency sealing device for oil and gas pipeline leaks is designed, comprising a base frame, a movable frame slidably connected to the upper end of the base frame, an electric telescopic rod fixedly connected to the upper end of the base frame for moving the movable frame vertically, movable plates slidably connected to both sides of the upper end of the movable frame, a spacing adjustment component connected to the movable frame for adjusting the distance between the two movable plates, a connecting plate detachably connected to the upper end of each movable plate, an open mask connected to one end of each connecting plate, and a sealing ring connected to the opening of each open mask.

[0006] Preferably, the base frame is coated with an anti-corrosion layer.

[0007] Preferably, the spacing adjustment component includes a servo motor, which is fixedly connected to the movable frame. A first bevel gear is fixedly connected to the output end of the servo motor. A bidirectional screw is rotatably connected to the movable frame. A second bevel gear is connected to the bidirectional screw. The second bevel gear meshes with the first bevel gear. Each movable plate has a threaded hole, and each threaded hole cooperates with the bidirectional screw.

[0008] Preferably, the number of teeth of the second bevel gear is greater than the number of teeth of the first bevel gear.

[0009] Preferably, the sealing ring is a corrosion-resistant rubber sealing ring.

[0010] Preferably, a liquid guiding mechanism is fixedly connected to the upper end of the movable frame. The liquid guiding mechanism includes a collection box, which is fixedly connected to the upper end of the movable frame. The open mask is located above the collection box, and the bottom end of the open mask is connected to a discharge pipe, which is connected to a solenoid valve.

[0011] Preferably, the inner bottom of the open-face mask is connected to a splash-proof pad.

[0012] Preferably, the anti-splash pad is a modified polypropylene meltblown fabric pad.

[0013] The present invention provides a rapid emergency sealing device for oil and gas pipeline leaks, which has the following advantages:

[0014] After the spacing adjustment component is activated, the two movable plates move towards each other a set distance. Each movable plate moves the open mask a set distance through the connecting plate. After the two open masks move towards each other a set distance, they come into contact. The sealing ring seals the gap between the open mask and the pipe. After the two open masks come into contact and cooperate, they cover and block the connection of the pipe. There is no need to tighten the bolts. The sealing speed is fast and the sealing effect is good. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Referring to Figures 1-3, a rapid emergency sealing device for oil and gas pipeline leaks includes a base frame 1. The base frame 1 is coated with an anti-corrosion layer, which is a polyethylene anti-corrosion layer. The anti-corrosion layer protects the base frame 1 from corrosion, slows down the rate of corrosion, and extends the service life of the base frame 1. A movable frame 2 is slidably connected to the upper end of the base frame 1. An electric telescopic rod 3 for moving the movable frame 2 vertically is fixedly connected to the upper end of the base frame 1. Movable plates 4 are slidably connected to both sides of the upper end of the movable frame 2. A spacing adjustment component 5 for adjusting the distance between the two movable plates 4 is connected to the movable frame 2. A connecting plate 6 is detachably connected to the upper end of each movable plate 4. An open mask 7 is connected to one end of each connecting plate 6. A sealing ring 8, which is a corrosion-resistant rubber sealing ring, is connected to the opening of each open mask 7.

[0022] Work process:

[0023] Before use, the base frame 1 is set below the pipe connection. When a leak occurs at the pipe connection, the electric telescopic rod 3 is powered on and starts to move the movable frame 2 upward by a set distance. The movable frame 2 moves the movable plate 4 upward, the movable plate 4 moves the connecting plate 6, and the connecting plate 6 moves the open mask 7. The pipe connection is located between the two open masks 7.

[0024] After the spacing adjustment component 5 is activated, the two movable plates 4 move towards each other by a set distance. Each movable plate 4 drives the open mask 7 to move by a set distance through the connecting plate 6. After the open mask 7 moves by a set distance, it contacts the pipe through the sealing ring 8. After the two open masks 7 move towards each other by a set distance, they contact each other. The sealing ring 8 seals the gap between the open mask 7 and the pipe. After the two open masks 7 contact and cooperate, they cover and seal the connection of the pipe. There is no need to tighten the bolts. The sealing speed is fast and the sealing effect is good.

[0025] Example 2: When adjusting the distance between the two movable plates 4, the spacing cannot be precisely adjusted. Referring to Figure 2, as another preferred embodiment of this utility model, the difference from Example 1 is that the spacing adjustment component 5 includes a servo motor 51, which is fixedly connected to the movable frame 2. The output end of the servo motor 51 is fixedly connected to a first bevel gear 52. A bidirectional screw 53 is rotatably connected to the movable frame 2, and a second bevel gear 54 is connected to the bidirectional screw 53. The second bevel gear 54 meshes with the first bevel gear 52. The number of teeth of the second bevel gear 54 is greater than the number of teeth of the first bevel gear 52. Each movable plate 4 has a threaded hole, and each threaded hole cooperates with the bidirectional screw 53.

[0026] After the servo motor 51 starts, it drives the first bevel gear 52 to rotate. The first bevel gear 52 drives the second bevel gear 54 to rotate. Since the number of teeth of the second bevel gear 54 is greater than the number of teeth of the first bevel gear 52, the speed of the second bevel gear 54 is adjusted. The second bevel gear 54 drives the bidirectional screw 53 to rotate. After the bidirectional screw 53 rotates, the distance between the two movable plates 4 is adjusted, and the spacing can be precisely adjusted.

[0027] Example 3: In the event of a leak, oil falls onto the spacing adjustment component 5, causing it to become dirty and affecting its operation. Referring to Figure 4, as another preferred embodiment of this utility model, the difference from Example 1 is that a liquid guiding mechanism 9 is fixedly connected to the upper end of the movable frame 2. The liquid guiding mechanism 9 includes a collection box 91, which is fixedly connected to the upper end of the movable frame 2. An anti-splash pad, which is a modified polypropylene meltblown fabric pad, is connected to the bottom of the open mask 7. The open mask 7 is located above the collection box 91, and the bottom end of the open mask 7 is connected to a discharge pipe 92. A solenoid valve 93 is connected to the discharge pipe 92. The collection box 91 collects the fallen oil, preventing it from falling onto the spacing adjustment component 5 and affecting its operation. The anti-splash pad reduces the collision between the oil and the collection box 91, reducing oil splashing. After the solenoid valve 93 is opened, the oil in the collection box 91 is released from the discharge pipe 92.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
