Description

A grounding device for petroleum engineering

Technical Field

The utility model belongs to the technical field of petroleum engineering, and specifically relates to a grounding device for petroleum engineering.

Background technique

Petroleum engineering is the general term for a series of engineering and process technologies implemented to establish suitable flow channels and optimize lifting methods based on the characteristics of oil, gas and reservoirs, so as to economically and efficiently extract deep underground oil and gas from oil and gas reservoirs to the ground. The grounding device used in petroleum engineering is a device buried in the soil that can conduct lightning current, fault current, static current, etc. and disperse it into the earth to ensure the normal operation of equipment and the safety of operators.

CN211376952U is retrieved and disclosed as a grounding device for petroleum engineering infrastructure, including an insulating box, a grounding wire inlet is arranged on the top of the insulating box, a fixing plate is installed on the bottom inner wall of the insulating box, and a fixing groove is arranged inside the fixing plate. The output shaft can be rotated by electrically connecting the input end of the motor with the output end of the external power supply, and further, the first rotating wheel is rotated by connecting the second rotating wheel with the belt, and the connecting rod, the threaded column and the drill bit are rotated quickly by rotating the first rotating wheel and the second rotating wheel, so that a large amount of earthwork can be avoided for landfill, and the grounding device can be driven into the deep ground through the rapid rotation of the drill bit, saving a lot of manpower and material resources. The active connection between the threaded joint and the threaded column can facilitate the staff to quickly replace the drill bit because the drill bit is easily corroded deep in the ground for a long time.

However, the inventors have discovered through exploration that the technical solution still has at least the following defects: in the above-mentioned device, the grounding wire is connected to the wiring piece through a provided grounding wire entrance, but when the grounding wire passes through the grounding wire entrance and extends into the insulation box, the wiring wire will be bent and entangled, and people are required to hold the end of the grounding wire by hand to avoid this phenomenon; when the grounding device goes deep into the earth's surface and the insulation box is stable, due to long-term work, the gaps in the grounding wire entrance will cause dust to float into the insulation box, polluting the working environment inside the insulation box, directly affecting the service life of the working components inside the insulation box.

In view of this, the present utility model is proposed.
