Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, specifically to a corrosion-resistant electrical wiring device for oil fields. Background Technology

[0002] Oil fields are often accompanied by media containing sulfur-containing oil and gas, brine, hydrogen sulfide, and carbon dioxide. These substances corrode metal components through electrochemical and chemical corrosion. Electrical wiring equipment is the nerve node of the oil field's power system, responsible for the stable connection of power transmission and signal links. The technological development of corrosion-resistant electrical wiring equipment for oil fields is driven by the extreme environment and core functional requirements of oil fields.

[0003] Existing devices primarily seal wiring through-holes using conduits. These devices are often similar to control junction boxes used in acidic environments. The structure of device CN214479356U includes a housing and a protective cover. A connecting ball groove is provided at the connection between the housing and the protective cover, and a sealing device is installed within the connecting groove. Multiple conduits are arranged around the housing, and sealing nuts are installed at the ends of the conduits. A spherical connecting strip adapted to the connecting groove is provided on the protective cover. This invention offers good sealing performance, is unaffected by external conditions, and the junction box housing is corrosion-resistant, effectively protecting the internal wiring. However, there are still areas for improvement in this device.

[0004] Existing equipment mainly uses fixed-specification conduits for sealed wiring, making it difficult to effectively seal and protect the plug terminals and terminals with covers in some devices. This leads to corrosion of electrical components by sulfur-containing oil and gas. Simultaneously, some devices cannot effectively seal unused channels with plungers or other components, allowing sulfur-containing oil and gas to enter the terminal block through these channels, reducing the equipment's efficiency and usability. Therefore, to address these issues, a corrosion-resistant electrical wiring device for oilfields is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant electrical wiring device for oilfields, addressing the problem mentioned in the background section that existing devices primarily use fixed-specification conduits for sealed wiring, making it difficult to effectively seal and protect the plug terminals and terminals with covers, thus leading to corrosion of electrical components by sulfur-containing oil and gas. Furthermore, some devices struggle to seal unused channels with plungers or other components, allowing sulfur-containing oil and gas to enter the terminal block through these channels.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant electrical wiring device for oil fields, comprising a connector, a wire fixedly connected to the top of the connector, a plug-in terminal fixedly connected to the top of the wire, a terminal block inserted into the outer wall of the plug-in terminal, a power supply line fixedly connected to the top center of the terminal block, a cover fitted onto the outer wall of the terminal block, a protective mechanism on the top of the cover, and a sealing mechanism on the upper part of the inside of the cover.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 One embodiment provided by this utility model: A corrosion-resistant electrical wiring device for oil fields includes a connector 11, a wire 12 fixedly connected to the top of the connector 11, a plug-in terminal 13 fixedly connected to the top of the wire 12, a terminal block 14 inserted into the outer wall of the plug-in terminal 13, a power supply line 15 fixedly connected to the middle of the top of the terminal block 14, a cover 16 sleeved on the outer wall of the terminal block 14, a protective mechanism 2 provided on the top of the cover 16, and a sealing mechanism 3 provided on the upper part of the inside of the cover 16.

[0020] The plug-in terminal 13 is J-shaped. The outer wall of the terminal block 14 has a corresponding groove, and the inner wall of the cover 16 also has a corresponding groove. This design ensures that the plug-in terminal 13 is tightly fitted between the terminal block 14 and the cover 16. The J-shaped plug-in terminal can be stably inserted into the terminal block, effectively preventing it from being pulled off by external forces.

[0021] The protective mechanism 2 includes a wire sleeve 21, the bottom of which is fixedly connected to the top center of the terminal block 14. A sealing ring 22 is fixedly connected to the middle of the outer wall of the wire sleeve 21, and a wire hole is opened on the top of the cover 16. This design ensures that the wire hole of the cover 16 is sealed onto the outer wall of the wire sleeve 21. A mounting thread 23 is opened on the upper part of the outer wall of the wire sleeve 21, and a threaded sleeve 24 is threaded onto the outer wall of the mounting thread 23. This design allows the threaded sleeve 24 to drive the cover 16 to be threaded onto the upper part of the outer wall of the wire sleeve 21. A limiting ring 25 is fixedly connected to the bottom of the threaded sleeve 24, and a limiting sleeve 26 is fitted onto the outer wall of the limiting ring 25. The bottom of the limiting sleeve 26 is fixedly connected to the top center of the cover 16. This design allows the threaded sleeve 24 to drive the limiting ring 25 to rotate within the limiting sleeve 26, thus allowing the threaded sleeve 24 to drive the cover 16 to be fitted onto the outside of the terminal block 14.

[0022] The sealing mechanism 3 includes a telescopic rod 31. The top end of the telescopic rod 31 is fixedly connected to the top of the inner wall of the cover 16, and the bottom end of the telescopic rod 31 is fixedly connected to a sliding frame 32. A plunger 33 is fixedly connected to the outer side of the sliding frame 32, and the outer wall of the plunger 33 is slidably disposed in a groove in the inner wall of the cover 16. This design allows the sliding frame 32 to drive the plunger 33 to rotate in a limited position, enabling the plunger 33 to be inserted into the groove between the terminal block 14 and the cover 16. A spring 34 is fixedly connected to the top of the inner wall of the cover 16, located on the outer ring of the telescopic rod 31. The bottom end of the spring 34 is fixedly connected to the top of the sliding frame 32. This design allows the spring 34 to drive the sliding frame 32 and the plunger 33 to slide downwards.

[0023] Working principle: When it is necessary to protect the terminal block 14, firstly, manually rotate the screw sleeve 24. The screw sleeve 24 is threaded onto the upper part of the outer wall of the sleeve 21. At the same time, the screw sleeve 24 drives the limiting ring 25 to rotate within the limiting sleeve 26, so that the limiting sleeve 26 drives the top of the inner wall of the cover 16 to be tightly pressed against the top of the sealing ring 22, thus realizing the protection operation of the terminal block 14.

[0024] When the slide needs to be sealed, the spring 34 in a compressed state first drives the sliding frame 32 to slide downward. The sliding frame 32 drives the plunger 33 to be inserted into the slide between the terminal block 14 and the cover 16, thus realizing the sealing operation of the slide. The operation ends here.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
