Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas metal pipeline technology, specifically to an anti-static grounding device suitable for gas metal pipelines. Background Technology
[0002] Gas metal pipelines are key facilities for transporting gas. They are commonly made of materials such as steel, copper, and stainless steel, and their high strength, excellent sealing performance, and corrosion resistance ensure the safe and stable transmission of gas. They are widely used in urban gas transmission and distribution, industrial gas supply, and gas storage, continuously supplying energy from the gas source to end users for residential life, commercial activities, and industrial production. They are the "lifeline" of the modern gas supply system.
[0003] In ensuring the safety of gas metal pipelines against static electricity, the proper installation of drainage lines is crucial. Considering the flammable and explosive nature of the gas transported, drainage lines are typically installed on the pipeline surface. This installation method not only effectively avoids interference with the internal structure of the pipeline and the gas transport process, but also, through reliable electrical connections, promptly dissipates static electricity generated during pipeline operation due to friction and flow, minimizing the risk of safety accidents caused by static electricity accumulation and thus building a solid safety barrier for gas transport.

[0026] This utility model provides the following technical solution:
[0027] Example 1
[0028] Combination Figures 1-4 An anti-static grounding device suitable for gas metal pipelines includes a gas metal pipeline 1, a first metal ring 2 and a second metal ring 5. The first metal ring 2 and the second metal ring 5 are disposed on the surface of the gas metal pipeline 1. The first metal ring 2 and the second metal ring 5 are provided with a plug-in mechanism 4. The plug-in mechanism 4 is provided with a fixing mechanism 3. The inner rings of the first metal ring 2 and the second metal ring 5 are provided with plug-in slots 6.
[0029] The insertion mechanism 4 includes a slot 43, which is opened at the upper and lower ends of the back of the first metal ring 2. The upper and lower ends of the front of the second metal ring 5 are respectively fixedly connected to the insertion blocks 42. The outer side of the upper and lower insertion blocks 42 is provided with a long groove 41. The openings of the upper and lower long grooves 41 are corresponding to each other. A long block 44 is inserted into the long groove 41. A connecting plate 45 is fixedly connected to the outer side of the left and right long blocks 44. There are two connecting plates 45. The two connecting plates 45 are set at the top and bottom of the first metal ring 2. A fixing rod 46 is fixedly connected to the left and right sides of the connecting plate 45. A rotating plate 47 is rotatably connected to the surface of the fixing rod 46. A connecting seat 49 is fixedly connected to the left and right sides of the first metal ring 2. A rectangular groove 48 is opened inside the connecting seat 49.
[0030] There are four insert blocks 42 and four slots 43, which are in pairs. The back of the slot 43 is open. The surface of the insert block 42 and the inside of the slot 43 are inserted. There are four rectangular slots 48, which are in pairs. The outer side and front of the rectangular slots 48 on the upper and lower sides are open. The surface of the rotating plate 47 and the inside of the rectangular slot 48 are inserted. The top and bottom of the first metal ring 2 are provided with through slots. The surface of the long block 44 is inserted through the through slots provided at the top and bottom of the first metal ring 2.
[0031] Furthermore, the second metal ring 5 drives the insert block 42 to be inserted into the slot 43, the connecting plate 45 drives the long block 44 to be inserted into the long groove 41, and the rotating plate 47 is rotated on the surface of the fixed rod 46 so that the rotating plate 47 is inserted into the rectangular groove 48, which can initially restrict the first metal ring 2 and the second metal ring 5 when they are assembled on the surface of the gas metal pipeline 1.
[0032] Example 2
[0033] See Figures 1-6 Furthermore, based on Embodiment 1, the fixing mechanism 3 includes a T-shaped groove 301. The T-shaped groove 301 is opened on the left and right sides of the first metal ring 2. The T-shaped groove 301 is set at the top and bottom of the insertion slot 6. Mounting plates 38 are fixedly connected to the upper and lower surfaces of the first metal ring 2 respectively. Connecting rods 35 are fixedly connected to both ends of the back of the mounting plates 38 respectively. A T-shaped slider 37 is slidably connected inside the T-shaped groove 301. A movable seat 36 is fixedly connected to the outside of the T-shaped slider 37. A hinge plate 34 is hinged to the side of the movable seat 36 near the connecting seat 49. A T-shaped slide 33 is hinged to the other side of the hinge plate 34. A block 39 is fixedly connected to the other side of the T-shaped slide 33. A bolt 32 is threadedly connected to the block 39 and the connecting seat 49. A square groove 31 is opened on the front of the rotating plate 47.
[0034] The front of the square groove 31 is set to be open, and the inside of the square groove 31 is inserted into the surface of the block 39. There are four connecting rods 35, which are in pairs. Two connecting rods 35 are set on the outside of two connecting seats 49. The inside of the T-shaped slide seat 33 is slidably connected to the surface of the connecting rods 35.
[0035] Furthermore, the moving seat 36 drives the T-shaped slider 37 to slide within the T-shaped groove 301. When the moving seat 36 moves, the T-shaped slider 33 slides on the surface of the connecting rod 35. At the same time, the T-shaped slider 33 drives the block 39 to be inserted into the square groove 31. The block 39 is firmly inserted into the square groove 31 using the bolt 32, thus fixing the first metal ring 2 and the second metal ring 5 onto the surface of the gas metal pipeline 1.
[0036] In actual operation, when this device is used, longer or larger diameter gas metal pipes may generate more static electricity due to their large surface area, so it is generally necessary to increase the number of connecting wires. For example, for pipes longer than 50 meters or with a diameter greater than 200 millimeters, an anti-static connection line is usually installed every 20-30 meters to ensure that static electricity can be discharged in time. At intervals, the gas metal pipe 1 is connected to the building's lightning protection grounding terminal using a guide line, and one end of the guide line is welded to the surface of the gas metal pipe. This ensures that the static electricity generated on the pipe surface can be reliably conducted to the ground through the guide line, achieving the anti-static effect. When the first metal ring 2 and the second metal ring 5 are set on the surface of the gas metal pipe 1, the guide line is inserted into the insertion slot 6. At this time, the second metal ring 5 drives the insertion block 42 to be inserted into the slot 43, and the connecting plate 45 drives the long block 44 to be inserted into the long slot 41. The rotating plate 47 is rotated on the surface of the fixed rod 46, so that the rotating plate 47 is inserted into the rectangular slot 48. This can initially restrict the first metal ring 2 and the second metal ring 5 when they are assembled on the surface of the gas metal pipe 1.
[0037] The movable seat 36 is pushed to drive the T-shaped slider 37 to slide in the T-shaped groove 301. When the movable seat 36, the hinge plate 34 and the T-shaped slider 33 are hinged together, the movable seat 36 moves down and the T-shaped slider 33 can slide on the surface of the connecting rod 35. At the same time, the T-shaped slider 33 drives the block 39 to be inserted into the square groove 31. The block 39 is firmly inserted into the square groove 31 by using the bolt 32, so that the first metal ring 2 and the second metal ring 5 can be fixedly set on the surface of the gas metal pipe 1.
[0038] When gas flows inside a metal pipe, static electricity is generated due to friction and other reasons. If this static electricity cannot be discharged in time, it may accumulate to a certain level and cause electrostatic discharge, generating an electric spark, which could ignite the surrounding gas and cause serious safety accidents such as explosions. The connecting wire can quickly guide the static electricity on the pipe surface to the ground, so that the pipe is in a state of electrostatic equilibrium and eliminates the potential danger of static electricity.
