Description

Technical Field

[0001] This application relates to the technical field of submarine pipeline monitoring, and in particular to a submarine pipeline scour monitoring device. Background Technology

[0002] Submarine natural gas pipelines are vital channels for transporting marine oil, natural gas, and other mineral resources, and their safety and stability are crucial for ensuring global energy supply. Due to the unique environment in which submarine pipelines operate, they are affected by various factors during their service life, including ocean currents, waves, erosion, and corrosion, with erosion and corrosion being particularly serious problems.

[0003] Therefore, monitoring cameras are installed along the sides of subsea pipelines to monitor parameters such as stress, corrosion, displacement, and settlement in real time. This allows for the timely detection and early warning of potential risks, enabling appropriate preventative measures to be taken and reducing the risk of accidents. In practice, a single fixed monitoring camera is typically used to monitor the entire pipeline. However, the potential risk locations may differ for different parts of the pipeline, or there may be more than one location that needs monitoring. Therefore, the camera needs to be frequently adjusted according to the situation, as a single monitoring camera cannot meet such monitoring requirements. Utility Model Content

[0004] To facilitate multi-faceted monitoring of different pipelines, this application provides a subsea pipeline scour monitoring device.

[0005] This application provides a subsea pipeline scour monitoring device, which adopts the following technical solution: A subsea pipeline scour monitoring device includes a structural ring for fixing to the outside of the pipe body and a monitoring head. A fixed base is slidably disposed on the structural ring. Several mounting grooves are provided on the structural ring along the circumference. A drive column is rotatably connected in the mounting groove. The outer circumferential wall of the drive column has protruding teeth. The fixed base has a toothed groove for cooperating with the protruding teeth.

[0006] By adopting the above technical solution, the structural ring will be set on the outside of the pipeline as a fixed position. According to the actual monitoring position required, a corresponding number of fixed bases will be installed on the structural ring. At the same time, according to the corresponding monitoring situation, the drive column will be rotated to move the fixed bases along the ring surface of the structural ring, so as to fine-tune the position of the monitoring head and obtain better monitoring effect. Furthermore, multiple monitoring heads can be added as needed. In subsequent monitoring processes, the position of the monitoring heads can also be adjusted again as needed to facilitate monitoring.

[0007] Preferably, the two sides of the structural ring have concave sliding ring grooves, and the fixed base has a slide that is inserted into and slidably disposed in the sliding ring grooves.

[0008] Preferably, the edge of the structural ring has a notch, the notch allowing the slide to be radially inserted into the sliding ring groove.

[0009] Preferably, the drive column is rotatably connected to the mounting groove via a rotating shaft, a drive rod is inserted through the rotating shaft, the drive rod is circumferentially fixed and axially slidingly connected to the rotating shaft, and the end of the drive rod is threadedly connected to the structural ring.

[0010] Preferably, the drive rod includes a front section that is a hexagonal prism and a rear section that is a threaded column, the rotating shaft has a receiving groove adapted to the front section, and the cross-sectional area of ​​the rear section is smaller than that of the front section.

[0011] Preferably, the side of the fixed base is provided with an avoidance ring groove for inserting a tool and rotating the drive rod.

[0012] In summary, this application includes at least one of the following beneficial technical effects: the structural ring will be set on the outside of the pipeline as a fixed position. According to the actual monitoring position required, a corresponding number of fixed bases will be installed on the structural ring. At the same time, according to the corresponding monitoring situation, the drive column will be rotated to move the fixed bases along the ring surface of the structural ring, so as to achieve fine adjustment of the position of the monitoring head and obtain better monitoring effect. Furthermore, multiple monitoring heads can be added according to the actual situation. In subsequent monitoring processes, the position of the monitoring head can also be adjusted again as needed to facilitate monitoring. Attached Figure Description

Detailed Implementation

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] This application discloses a subsea pipeline scour monitoring device, referring to... Figure 1 It includes a structural ring 100 for fixing to the outside of the pipe body, a fixed base 110 slidably disposed on the structural ring 100, and a monitoring head 111 mounted on the fixed base 110. The position of the monitoring head 111 can be adjusted via the fixed base 110.

[0020] Reference Figure 1 , Figure 2 The structural ring 100 has concave sliding ring grooves 112 on both sides of its annular surface. The fixed base 110 has a slide 113 that is inserted into and slidably disposed within the sliding ring grooves 112. The edge of the structural ring 100 has a notch 114, which allows the slide 113 to be radially embedded into the sliding ring grooves 112 to slide on the structural ring 100. Multiple fixed bases 110 can also be installed through this notch 114.

[0021] Reference Figure 2 , Figure 3 The structural ring 100 has several mounting grooves 115 along its circumferential direction. A drive column 116 is rotatably connected within the mounting groove 115. The outer circumferential wall of the drive column 116 has protruding teeth 117. The fixed base 110 has a toothed groove 118 for engaging with the protruding teeth 117. The drive column 116 is rotatably connected to the mounting groove 115 via a rotating shaft 120. A drive rod 121 passes through the rotating shaft 120. The drive rod 121 is circumferentially fixed and axially slidingly connected to the rotating shaft 120, and its end is threaded to the structural ring 100.

[0022] Reference Figure 3 , Figure 4 The drive rod 121 includes a front section 122, which is a hexagonal prism, and a rear section 123, which is a threaded column. The rotating shaft 120 has a receiving groove 124 that fits the front section 122. The cross-sectional area of ​​the rear section 123 is smaller than that of the front section 122. When inserted, the rear section 123 will pass through the receiving groove 124 and be threaded onto the structural ring 100. The distance that the rear section 123 can be turned allows the drive column 116 to complete multiple rotations. During rotation, since the front section 122 can cooperate with the inner wall of the rotating shaft 120, the drive column 116 can rotate. The convex tooth 117 cooperates with the tooth groove 118, so that the fixed base 110 will move along the extension direction of the structural ring 100, achieving a fine adjustment effect.

[0023] Furthermore, a hexagonal groove is provided at the end of the front section 122 to facilitate the rotation of the drive rod 121 by the tool. At the same time, in order to avoid collision with the side of the fixed base 110 during rotation, an avoidance ring groove 125 is provided for the tool to insert and rotate the drive rod 121. In order to facilitate the sliding of the fixed base 110, the ends of the drive rod 121 and the rotating shaft 120 are not higher than the outer surface of the structural ring 100.

[0024] It is worth noting that the drive rod 121 is inserted into the rotating shaft 120 after the fixed base 110 is installed, depending on whether the fixed base 110 is installed, and the number of monitoring heads 111 is determined accordingly.

[0025] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
