Description

Technical Field

[0001] This utility model relates to the field of perimeter security technology, specifically a perimeter security line device for oilfield production. Background Technology

[0002] In oilfield production operations, warning lines are a crucial safety measure to ensure safe production. These visual boundary markers are primarily used in three key scenarios: First, warning lines are erected around high-risk work areas involving high temperatures, high pressures, toxic or hazardous materials, or flammable and explosive substances, clearly delineating the danger zone through prominent signage. Second, as a personnel control measure, they effectively prevent unnecessary personnel from entering the work area, reducing human-caused accidents at their source. Finally, in emergency situations, warning lines can quickly establish on-site isolation zones, creating safe working space for accident response and preventing secondary disasters. This multi-layered safety protection system significantly improves the safety management level of oilfield production sites.

[0003] In oilfield production operations, warning lines are crucial facilities for ensuring safe production. Traditional warning devices typically consist of stainless steel pipes, a base, and telescopic straps. While simple in structure, they have significant shortcomings: large size and heavy weight, relying on manual handling and deployment, which is not only time-consuming and labor-intensive but also inefficient, and prone to theft due to a lack of anti-theft design. Existing portable and mobile warning devices, while easy to carry, are too lightweight to withstand strong winds, easily damaged or tipped over, severely affecting their effectiveness, and similarly lack anti-theft design. Therefore, how to improve the wind resistance and durability of the device while ensuring its portability and mobility, and also incorporate anti-theft functionality, has become a key technical challenge in the current research and development of oilfield warning devices.

[0004] To address this, we developed a new oilfield production perimeter warning line device. Utility Model Content

[0049] A mounting groove 15 is provided on one side of the outer surface of the column 2. A drive handwheel is installed between the mounting groove 15 and the column 2. The drive handwheel includes a drive ring 8, which is rotatably connected to the inner top and inner bottom of the mounting groove 15. A gear ring 14 is fixedly connected to the inner surface of the drive ring 8. A first gear 17 is meshed with the inner surface of the gear ring 14. A second gear 16 is meshed with the outer surface of the first gear 17. The mounting shaft of the second gear 16 extends through the inner bottom of the mounting groove 15 into the slot 18 and is rotatably connected to the column 2.

[0050] The bottom of the column 2 is provided with a slot 18. The outer wall of the column 2 is provided with a plurality of storage holes 20 that penetrate into the slot 18. The slot 18 is provided with a screw 19, and the mounting shaft of the second gear 16 is fixedly connected to the screw 19. The outer surface of the screw 19 is threaded with a movable seat 21. The movable seat 21 and the plurality of storage holes 20 are jointly installed with a support rod assembly. The plurality of support rod assemblies include a connecting block 22, and the connecting block 22 is fixedly connected to the movable seat 21. The outer surface of the connecting block 22 is rotatably connected to a connecting rod 26. The other end of the connecting rod 26 is rotatably connected to a fixing block 25. The bottom of the fixing block 25 is fixedly connected to a support rod 1, and the support rod 1 is rotatably connected to the inner walls on both sides of the adjacent storage hole 20. The bottom of the screw 19 is fixedly connected to a stop block 23. The support mechanism is made of high-strength aluminum alloy. The unique design of the connecting rod 26 allows it to withstand the impact of a level 7 wind when unfolded.

[0051] Working principle: During use, the column 2 is moved to the set position, and then the drive ring 8 is rotated. The drive ring 8 drives the gear ring 14, which in turn drives the second gear 16 through the first gear 17. The second gear 16 drives the movable seat 21 to descend. The movable seat 21 drives one end of the connecting rod 26 to descend through the connecting block 22. The connecting rod 26 drives the support rod 1 to swing around the pivot point of the support rod 1 and the storage hole 20 through the fixing block 25 until the support rod 1 and the column 2 are perpendicular. The stability of the column 2 is improved by the support rod 1 and the connecting rod 26. The above operation is repeated until the required column 2 is arranged. Pull the insertion rod body 13. The insertion rod body 13 drives one end of the two warning strips 3 away from the column 2. When the end of the warning strip 3 moves, it drives the rotating rod 30 to rotate. When the rotating rod 30 rotates, it drives the spiral spring 29 to undergo elastic deformation until the insertion rod body is lowered. Insert the rod 13 into the slot 5 on the other post 2, then press the locking bar. The locking bar passes through the buckle plate 12, and the connection between the rod body 13 and the slot 5 is completed by the mechanical combination lock 7. Then repeat the above operation until all the steps of the warning tape 3 are completed. When someone steals, the mechanical combination lock 7 can prevent the rod body 13 from separating from the slot 5, making the warning tape large and difficult to steal. When the two posts 2 are close to each other, the spiral spring 29 inside the post 2 drives the rotating rod 30 to rotate. The rotating rod 30 winds up the warning tape 3. During the winding process, the warning tape 3 drives the detection roller 33 to rotate. The encoder 10 detects that the rotation angle of the detection roller 33 exceeds the threshold and sends a signal to the controller 28. The controller 28 controls the sound and light alarm 9 to run and issue a sound and light alarm. At the same time, through its built-in communication module, the signal is sent to the receiving terminal (such as a computer or mobile phone) to issue an alarm.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
