Description

Technical Field

[0001] This invention relates to the field of non-metallic pipe technology, specifically to a static electricity discharge device for non-metallic pipes. Background Technology

[0002] Non-metallic pipelines possess excellent corrosion resistance, a certain degree of flexibility, ease of maintenance, and convenient leak detection. While typical metal pipelines buried underground will experience perforation and leakage within 10-15 years, some flexible underground pipelines can last up to 30 years. Therefore, they were used earlier for transporting oil. Non-metallic oil pipelines are longer, significantly reducing the need for bends and welding, and their laying speed is far faster than traditional metal pipelines. Static electricity is generally generated during oil transportation in non-metallic pipelines. However, the high resistance of the non-metallic pipe wall makes it difficult to discharge static electricity. Excessive accumulation of static charge can lead to electrostatic discharge. Therefore, copper wire is typically wrapped around the outside of non-metallic pipes, with both ends connected to the ground to shield against static electricity. However, this method still cannot completely eliminate the static charge inside the non-metallic pipeline, and the large amount of copper wire used for wrapping the pipe results in waste. Therefore, we propose a static electricity discharge device for non-metallic pipelines. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a non-metallic pipe static electricity discharge device.

The conductive device is used to discharge the static charge inside the non-metallic pipe to the outside of the non-metallic pipe. The conductive device includes a conductive metal wire. A plurality of internal metal wires are installed inside the conductive metal wire, and a plurality of external metal wires are installed outside the conductive metal wire.

[0006] The non-metallic pipe is provided with a conductive upper interface and a conductive lower interface at both ends. The conductive upper interface and the conductive lower interface correspond to each other and are made of conductive material. They are used to conduct static charge at both ends of the non-metallic pipe to the outside of the non-metallic pipe.

[0010] Preferably, a plurality of second fixing blocks are fixedly connected to the periphery of the upper inner ring, and a first bolt is arranged in each of the second fixing blocks.

[0011] Preferably, an interface inner ring is fixedly installed on the upper inner ring, and a first nut is arranged on the first bolt.

[0012] Preferably, the electrically-conductive lower interface comprises a lower inner ring, and the outer wall of the lower inner ring and the inner wall of the non-metal pipeline are in close contact with each other.

[0013] Preferably, a plurality of lower threaded holes are arranged on the lower inner ring, and an interface outer ring is fixedly installed on the lower inner ring.

[0014] Preferably, a plurality of arc-shaped blocks are fixedly installed on the periphery of the interface outer ring, an arc-shaped hole is arranged in each of the arc-shaped blocks, and the outer wall of the interface inner ring and the inner wall of the interface outer ring have the same radius.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] 1. The electrostatic charge generated in the non-metal pipeline can be discharged to the outside of the non-metal pipeline through the electrically-conductive device, and the electrostatic charge can be guided to the ground through the first fixing block and the electrically-conductive material, thereby preventing the accumulation of electrostatic charge in the non-metal pipeline and preventing electrostatic breakdown accidents.

[0018] 2. The electrostatic charge on the inner connecting metal wire in contact with the upper inner ring and the electrostatic charge on the oil passing through the electrically-conductive upper interface can be discharged to the ground through the electrically-conductive upper interface.

[0019] 3. The electrostatic charge on the inner connecting metal wire in contact with the lower inner ring and the electrostatic charge on the oil passing through the electrically-conductive lower interface can be discharged to the ground through the electrically-conductive upper interface.
