Description

Technical Field

[0001] This utility model relates to the field of long-distance oil and gas pipeline technology, specifically to an internal detection device for long-distance oil and gas pipelines that facilitates later maintenance. Background Technology

[0002] Long-distance oil and gas pipelines are subject to various factors during operation, such as corrosion and cracks. These problems can lead to oil and gas leaks, causing not only economic losses but also serious harm to the environment and human health. Therefore, regular internal inspections of long-distance oil and gas pipelines are essential.

[0003] A search revealed an existing technology, such as CN218866123U, for a pipe detector, which includes an upper shell, a connecting plate, and an illumination mechanism. The lower surface edge of the upper shell has a first annular groove, and a lower shell is located below the upper shell. Ball bearings are placed inside the first and second annular grooves. Both the outer surfaces of the upper and lower shells are covered with a wear-resistant layer. Limiting posts are welded to the left and right sides of both the upper and lower shells. The connecting plate is located outside the limiting posts, and a cap is screwed onto the outer end of each limiting post. The illumination mechanism is located on the left and right sides of the upper surface of the upper shell. In this invention, the upper and lower shells are configured as two independent structures. The upper and lower shells are assembled through the cooperation of the limiting posts, limiting grooves, and connecting plate using a threaded connection. Therefore, the upper and lower shells are easy to disassemble, and the ball bearings can be replaced promptly when they are severely worn.

[0004] In summary, while existing pipeline detectors allow for timely replacement of ball bearings, the subsequent maintenance and replacement of cameras is inconvenient. Therefore, a new internal detection device for long-distance oil and gas pipelines that facilitates later maintenance is proposed. Utility Model Content

Under the action of the dual-head motor, the locking block moves. When the locking block completely disengages from the locking block groove opened in the connecting block, the wireless camera can be separated from the mounting slot, thereby allowing the wireless camera to be maintained or replaced.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: an internal detection device for long-distance oil and gas pipelines that is easy to maintain in the later stage. The wireless camera 1 has a connecting block 2 fixedly installed at the rear end, and the mounting groove 3 is provided with a limiting block 4 that works with the connecting block 2.

[0025] In a further embodiment, lighting lamps 301 are symmetrically arranged at one end of the mounting groove 3. The lighting lamps 301 facilitate the later illumination of the inside of the pipe, thereby making the wireless camera 1 capture clearer images. Both the lighting lamps 301 and the wireless camera 1 are located inside the transparent protective cover 302. The transparent protective cover 302 can provide a certain degree of protection for the lighting lamps 301 and the wireless camera 1.

[0026] In a further embodiment, positioning plates 303 are symmetrically arranged on the outer side of the mounting groove 3, and the positioning plates 303 are connected to the transparent protective cover 302 by bolts. The bolts can be removed later to remove the transparent protective cover 302.

[0027] Specifically, the limiting block 4 includes a dual-head motor 401, which can drive two sets of lead screw mechanisms 402 rotatably arranged inside the mounting slot 3 to rotate. The lead screw mechanism 402 is connected to the moving block 403. When the dual-head motor 401 drives the two sets of lead screw mechanisms 402 to rotate, it can drive the two sets of moving blocks 403 to move closer or further away from each other. The moving block 403 is connected to the moving plate 405 through the linkage rod 404. The moving plate 405 moves in the moving slot opened in the mounting slot 3. A locking block 406 is provided on one side of the moving plate 405. The connecting block 2 is provided with a locking block slot that cooperates with the locking block 406.

[0028] To further explain, the mounting groove 3 is symmetrically provided with limiting slide rods 4031 that are slidably connected to the moving block 403. The moving block 403 is slidably connected to the inside of the mounting groove 3. By setting the limiting slide rods 4031, the moving direction of the moving block 403 can be limited, thereby improving the stability of the moving block 403 when it moves.

[0029] When it is necessary to maintain or replace the wireless camera 1, remove the transparent protective cover 302. After the above operation is completed, turn on the dual-head motor 401. Under the action of the dual-head motor 401, the two sets of lead screw mechanisms 402 rotate, thereby driving the two sets of moving blocks 403 to move away. The moving blocks 403 drive the moving plate 405 and the locking block 406 to move through the linkage rod 404. When the two sets of locking blocks 406 are completely disengaged from the locking block slots opened in the connecting block 2, the wireless camera 1 can be separated from the mounting slot 3, thereby allowing the wireless camera 1 to be maintained or replaced.

[0030] Specifically, connecting sleeves 5 are symmetrically arranged on the outer side of the mounting groove 3, and connecting posts 6 are inserted inside the connecting sleeves 5. Telescopic round head locking blocks 7 that cooperate with connecting sleeves 5 are provided inside the connecting posts 6. One end of the connecting post 6 is connected to the arc-shaped contact plate 601, and several sets of ball bearings 602 are rotatably arranged on the outer side of the arc-shaped contact plate 601. When in use, the ball bearings 602 contact the inner wall of the pipe, thereby reducing the friction generated during contact. The telescopic round head locking blocks 7 facilitate the disassembly and installation of the connecting post 6 and the connecting sleeve 5, thereby facilitating the replacement of the arc-shaped contact plate 601 when the ball bearings 602 are damaged in the future.

[0031] Specifically, the telescopic round head block 7 includes four sets of round head blocks 701 symmetrically arranged, and one end of the round head block 701 is connected to the sliding plate 702. The sliding plate 702 is slidably connected to the sliding groove opened in the connecting column 6, and one side of the sliding plate 702 is connected to the inner wall of the sliding groove through a spring 703.

[0032] To further explain, the connecting sleeve 5 is provided with a movable through groove that works in conjunction with the round head locking block 701.

[0033] When the arc-shaped contact plate 601 needs to be replaced, pull the arc-shaped contact plate 601 outward. Under the action of the pulling force, the round head block 701 retracts inward. At this time, the sliding plate 702 moves and the spring 703 is in a compressed state. When the round head block 701 moves to a certain position, the connecting post 6 and the connecting sleeve 5 can be separated.

They are merely simplified descriptions for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
