Description

Technical Field

[0001] This utility model relates to the field of electrostatic grounding technology, and in particular to a novel optimized connection device for anti-static grounding of oil and gas pipelines. Background Technology

[0002] During oil and gas pipeline transportation, factors such as friction between the oil / gas and the pipeline inner wall, collisions between impurities in the oil / gas and the pipeline, and the turbulence of the oil / gas itself can all lead to the separation and accumulation of electrical charges, thus generating static electricity. If this static electricity is not discharged in time, it can accumulate to a certain level and cause electrostatic discharge, the energy of which is sufficient to ignite the oil / gas mixture, thereby causing a fire or explosion. To remove static electricity and conduct it underground, a grounding device is required. However, due to the different diameters of the pipelines, the device cannot be used for pipelines of different diameters, affecting its applicability. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that cannot be used with pipes of different diameters, thus affecting the applicability of the device, and to propose a new type of optimized connection device for anti-static grounding of oil and gas pipelines.

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

[0005] A novel anti-static grounding optimization connection device for oil and gas pipelines is designed, comprising a conductive strip, one end of which is fixedly connected to a connector, the other end of which passes through the connector, a bolt threaded through the connector, a conductive wire connected to the conductive strip, and a grounding nail fixedly connected to the conductive wire.

[0006] Preferably, an abutment ring is fixedly connected to the bolt, and the diameter of the abutment ring is larger than the diameter of the bolt.

[0007] Preferably, the bolt is a stainless steel bolt.

[0008] Preferably, a fixing frame is fixedly connected to the connector head, a pull column is provided through the fixing frame, a fixing ring is fixedly connected to the pull column, the fixing ring abuts against the bolt, and an elastic element is fixedly connected between the fixing ring and the fixing frame.

[0009] Preferably, the lower end of the fixing ring is provided with anti-slip texture.

[0010] Preferably, the conductive strip is provided with multiple limiting parts.

[0011] Preferably, the elastic element is a spring, and the spring is sleeved on the pull column.

[0012] Preferably, the conductive wire is a flat steel wire.

[0013] The present invention proposes a novel optimized connection device for anti-static grounding of oil and gas pipelines. The beneficial effect is that by adjusting the position of the conductive strip on the connector, the conductive strip can be made to abut against pipelines of different diameters. Then, the abutment is fixed by bolts, and static electricity is conducted to the ground along the conductive line, thereby improving the applicability of the device. Attached Figure Description

[0018] 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.

[0019] Example 1: Refer to Figure 1-3 A novel anti-static grounding optimization connection device for oil and gas pipelines includes a conductive strip 1, one end of which is fixedly connected to a connector 9, and the other end of the conductive strip 1 passes through the connector 9. A bolt 8 is threaded through the connector 9. A conductive wire 2, which is made of flat steel, is connected to the conductive strip 1. A grounding nail 3 is fixedly connected to the conductive wire 2 and inserted into the ground. By adjusting the position of the conductive strip 1 on the connector 9, the conductive strip 1 can be brought into contact with pipelines of different diameters. The connection is then fixed by the bolt 8. Static electricity on the pipeline is conducted to the ground along the conductive strip 1 and through the conductive wire 2, thereby improving the applicability of the device.

[0020] A retaining ring 10 is fixedly connected to bolt 8. The diameter of the retaining ring 10 is larger than the diameter of bolt 8, which is a stainless steel bolt. The retaining ring 10 is used to prevent bolt 8 from coming out of the threaded hole.

[0021] Example 2: In Example 1, the gas flow within the pipe causes airflow pulsations, which lead to periodic pressure changes and pipe vibrations. This can loosen bolt 8, affecting the fixation of the conductive strip 1. (Refer to...) Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, a fixing frame 5 is fixedly connected to the connector 9, a pull post 6 is provided through the fixing frame 5, a fixing ring 11 is fixedly connected to the pull post 6, the fixing ring 11 abuts against the bolt 8, and an elastic element, a spring 7, is fixedly connected between the fixing ring 11 and the fixing frame 5. The spring 7 is sleeved on the pull post 6 and is in a compressed state. Through the restoring force of the spring 7, the fixing ring 11 abuts against the nut of the bolt 8, which plays a limiting role for the bolt 8, thereby preventing the bolt 8 from loosening due to the vibration of the pipeline, which would affect the fixing effect of the conductive strip 1.

[0022] The lower end of the fixing ring 11 is provided with anti-slip texture. The anti-slip texture increases the surface roughness, which is beneficial to the fixing effect. Multiple limiting parts 4 are provided on the conductive strip 1. By using the limiting parts 4, the excess conductive strip 1 can pass through the limiting parts 4 and the conductive strip 1 can be limited.

[0023] 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.
