[0026] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0027] Corrosion detection of oil pipes typically employs corrosion detection devices. However, existing corrosion detection devices have limited range for oil pipe inspection, only capable of intelligently detecting certain specific areas. Furthermore, these devices suffer from poor stability and adaptability; they are also difficult to operate and install; and adopting intelligent detection equipment increases economic costs.

[0028] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an oil pipe corrosion detection device, such as... Figure 1 As shown, it includes a threaded seat 1, a gate valve 2, a threaded sleeve 3, and a corrosion detection rod 4. One end of the threaded seat 1 is provided with a threaded sleeve 3, and the other end of the threaded seat 1 is provided with a gate valve 2. The threaded seat 1, the gate valve 2, and the threaded sleeve 3 form a receiving cavity, and the corrosion detection rod 4 is located in the receiving cavity.

[0029] The corrosion detection rod 4 includes a corrosion detection plate 4.1, a corrosion detection connecting rod 4.2, a washer 4.3, and a countersunk bolt 4.4. The corrosion detection plate 4.1 is provided at one end of the corrosion detection connecting rod 4.2, and the corrosion detection plate 4.1 and the corrosion detection connecting rod 4.2 are connected by the countersunk bolt 4.4.

[0030] Oil pipe corrosion detection is achieved through the cooperation of threaded seat 1, gate valve 2, threaded sleeve 3 and corrosion detection rod 4. The threaded seat 1 and threaded sleeve 3 at both ends are respectively provided with external threads, and the threaded sleeve 3 is also provided with internal threads. In addition, the corrosion detection connecting rod 4.2 is also provided with external threads, so that the internal and external threads can be better matched to ensure the stability of oil pipe corrosion detection.

[0031] This invention allows for the determination of the dimensions of the threaded seat 1, threaded sleeve 3, and corrosion detection rod 4 according to the application scenario, thus improving applicability. During use, the user passes the corrosion detection rod 4 through both ends of the threaded seat 1, threaded sleeve 3, and gate valve 2 until the corrosion detection piece 4.1 is fully inserted into the oil pipe. Periodic removal allows for observation of corrosion conditions, simplifying the corrosion detection process. Especially in terms of data output, the simple installation and arrangement greatly improve corrosion detection efficiency and effectively reduce economic costs.

[0032] like Figure 2 and Figure 3 As shown, the threaded seat 1 and the gate valve 2 are detachably connected, and the threaded sleeve 3 and the threaded seat 1 are also detachably connected. The detachable connections between the threaded seat 1, the gate valve 2, and the threaded sleeve 3 allow for individual replacement of any component when needed, without requiring the replacement of the entire assembly.

[0033] One end of the corrosion detection connecting rod 4.2 is inside the threaded seat 1, the other end is inside the threaded sleeve 3, and the middle part of the corrosion detection connecting rod 4.2 is inside the gate valve 2. The corrosion detection connecting rod 4.2 has a threaded hole, and the corrosion detection plate has a round hole. A countersunk bolt 4.4 passes sequentially through the threaded hole of the corrosion detection connecting rod 4.2 and the round hole on the corrosion detection plate, connecting the corrosion detection connecting rod 4.2 and the corrosion detection plate.

[0034] The threaded seat 1 and threaded sleeve 3 are made of 30mm diameter steel pipe and are respectively provided with internal and external threads. The threaded sleeve 3 has a channel for placing the corrosion detection connecting rod 4.2, and the connecting channel is arranged along the axial direction of the corrosion detection connecting rod 4.2. The upper cylindrical part of the corrosion detection connecting rod 4.2 is provided with external threads that match the internal threads of the threaded sleeve 3. At the same time, the cylindrical protrusion of the front part of the corrosion detection connecting rod 4.2 mates with the protrusion of the threaded sleeve 3. The corrosion detection rod 4 passes through the threaded sleeve 3, the gate valve 2 and the threaded seat 1 in sequence until the O-ring on the corrosion detection connecting rod 4.2 contacts and seals with the protrusion on the threaded sleeve 3, and the corrosion detection plate 4.1 is completely placed inside the oil pipe.

[0035] The corrosion detection connecting rod 4.2 has a cylindrical structure at one end with external threads. These external threads match the internal threads of the threaded sleeve 3. The cylindrical protrusion at the front of the corrosion detection connecting rod 4.2 also matches the protrusion of the threaded sleeve 3. The corrosion connecting rod enters the oil pipe through the sleeve to detect corrosion, significantly reducing the difficulty of operating the detector. Furthermore, periodically removing the detection piece to check the corrosion status provides convenience for corrosion detection and further reduces usage and manufacturing costs.

[0036] The corrosion detection connecting rod 4.2 has a groove on its surface, and a washer 4.3, which is an O-ring, is placed inside the groove. One end of the washer 4.3 is tightly fitted with a protrusion on the threaded sleeve 3, and the other end of the washer 4.3 is tightly fitted with the groove on the corrosion detection connecting rod 4.2. The O-ring embedded in the corrosion detection rod 4 provides a sealing function. The corrosion detection rod 4 is threadedly inserted into the threaded sleeve 3 and extends out to the threaded seat 1 to achieve the purpose of detecting corrosion inside the oil pipe.

[0037] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
