Description

Technical Field

[0001] The utility model relates to the technical field of pipeline corrosion monitoring, in particular to a shale oil fracturing pipeline corrosion monitoring device. Background Art

[0002] Pipelines are widely used in the transportation of crude oil, natural gas, and refined oil and gas products, and are used in large quantities in the oil and gas transportation field. Since the media such as crude oil, natural gas, and refined oil and gas products transported in oil and gas pipelines are generally corrosive, the oil and gas pipelines are easily corroded and cracked after long-term use, thus leading to leakage.

[0003] The commonly used pipeline corrosion monitoring devices on the market require staff to hold the monitoring device and rotate it along the outer wall of the pipeline to detect the pipeline corrosion situation. This detection method can only perform irregular detection on local pipelines and cannot achieve comprehensive detection. At the same time, the detection method of holding the monitoring device is difficult to detect the bottom of the pipeline, very inconvenient to detect, and very labor-consuming for staff when the pipeline is long, reducing the work efficiency of the staff. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a shale oil fracturing pipeline corrosion monitoring device, which solves the problems of large detection difficulty and low efficiency of the existing pipeline corrosion detection equipment.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A shale oil fracturing pipeline corrosion monitoring device includes a right-angle block, and an arc-shaped groove and a gear cavity are opened at the bottom of the right-angle block. A first gear and a second gear are rotatably arranged inside the arc-shaped groove. The bottoms of the first gear and the second gear are respectively meshed with a first tooth ring and a second tooth ring, and both the first tooth ring and the second tooth ring are slidably arranged inside the arc-shaped groove. A plurality of corrosion detection heads are arranged on the inner sides of the first tooth ring and the second tooth ring.

[0007] A first bevel gear and a second bevel gear are arranged inside the gear cavity. The first bevel gear is connected to the first gear, and the second bevel gear is connected to the second gear. Both the first bevel gear and the second bevel gear are meshed with a third bevel gear arranged on the output shaft of the motor.

[0008] A pipeline corrosion detector body is further installed on the top of the right-angle block, and the pipeline corrosion detector body is connected to the corrosion detection heads.

[0009] In this solution, the motor drives the first bevel gear and the second bevel gear to rotate in opposite directions. The first bevel gear and the second bevel gear respectively drive the first gear and the second gear to transmit power. The first gear and the second gear respectively drive the first toothed ring and the second toothed ring to move in opposite directions until they wrap around the pipeline to be detected. Then, the corrosion detection heads inside the first toothed ring and the second toothed ring detect the pipeline, enabling a comprehensive detection of the entire circumference of the pipeline, with high detection efficiency. Moreover, it is also possible to detect pipelines at the bottom or pipelines installed in narrow spaces, reducing the working difficulty.

[0010] Further, a round rod is horizontally arranged at the bottom of the arc-shaped groove. Arc-shaped sliding grooves are respectively formed through the first toothed ring and the second toothed ring. The round rod passes through the arc-shaped sliding grooves and is slidably connected to the first toothed ring and the second toothed ring.

[0011] In this solution, the round rod is arranged through the arc-shaped sliding groove, which plays a limiting role for the first toothed ring and the second toothed ring, ensuring that they can move smoothly. At the same time, the design of the round rod can also prevent the first toothed ring and the second toothed ring from having too large a movement amplitude during forward or reverse movement, resulting in disconnection from the first gear and the second gear.

[0012] Further, T-shaped arc grooves are respectively formed on the sides of the first toothed ring and the second toothed ring. T-shaped arc blocks are arranged at positions corresponding to the T-shaped arc grooves on the inner wall of the arc-shaped groove. The T-shaped arc blocks are embedded in the T-shaped arc grooves.

[0013] In this solution, the T-shaped arc blocks are embedded in the T-shaped arc grooves to limit the movement paths of the first toothed ring and the second toothed ring, ensuring that they move along the two side walls of the arc-shaped groove respectively, and preventing them from coming into contact with each other and generating friction during movement.

[0014] Further, the first bevel gear is connected to the first gear through a cylinder, and the second bevel gear is connected to the second gear through a round cross bar, and the round cross bar is arranged inside the cylinder.

[0015] In this solution, the cylinder is used to drive the first bevel gear and the first gear to rotate synchronously, and the round cross bar is used to drive the second bevel gear and the second gear to rotate synchronously. The round cross bar is arranged inside the cylinder, and their rotation directions are opposite, realizing the reverse rotation of the first gear and the second gear.

[0016] Further, the motor is installed on the top of the right-angle block, and the output shaft of the motor penetrates through the gear cavity from the top of the right-angle block and is connected to the third bevel gear.

[0017] Further, a pair of L-shaped rods are respectively fixed on two opposite side faces of the right-angle block, and a roller is rotatably arranged between the two L-shaped rods on one side face.

[0018] In this solution, two rollers are designed. During the detection, the whole shale oil fracturing pipeline corrosion monitoring device can be moved along the pipeline to be detected. During the movement, the rollers are in direct contact with the pipeline and rotate, avoiding the direct contact and wear between the corrosion detection heads inside the first gear ring or the second gear ring and the pipeline to be detected.

[0019] Furthermore, handles are fixed on two opposite side surfaces of the right-angle block.

[0020] In this solution, the shale oil fracturing pipeline corrosion monitoring device can be moved through the handles, which is convenient to use.

[0021] The beneficial effects of the present utility model are as follows:

[0022] In the shale oil fracturing pipeline corrosion monitoring device provided by the present utility model, a first gear ring and a second gear ring are designed, and the first gear ring and the second gear ring are driven by a motor to rotate. When detecting the pipeline, the first gear ring and the second gear ring rotate around the pipeline to be detected for detection. All parts around the pipeline can be detected each time. After the detection of this part is completed, it can move along the pipeline to detect the next part of the pipeline, achieving comprehensive detection, high detection efficiency, and fast detection speed.

[0023] When the shale oil fracturing pipeline corrosion monitoring device provided by the present utility model detects the pipeline to be detected, the first gear ring and the second gear ring rotate around the pipeline. It can also detect the pipeline at the bottom of the pipeline or in narrow spaces close to the wall, etc. There is no need for the staff to hold the detection device and rotate it around the outer wall, which is convenient to use and reduces the detection difficulty.

[0032] As Figure 1 shown, this embodiment provides a shale oil fracturing pipeline corrosion monitoring device for detecting the corrosion degree of the pipeline. This shale oil fracturing pipeline corrosion monitoring device can comprehensively detect the pipeline, has high detection efficiency, and can also detect pipelines distributed in narrow spaces.

A plurality of corrosion detection heads 18 are arranged on the inner sides of the first tooth ring 14 and the second tooth ring 15. A first bevel gear 115 and a second bevel gear 116 are arranged inside the gear cavity 12. As Figure 3As shown, the first bevel gear 115 is connected to the first gear 111 through the cylinder 113, and the second bevel gear 116 is connected to the second gear 112 through the round cross bar 114. The round cross bar 114 is arranged inside the cylinder 113. Both the first bevel gear 115 and the second bevel gear 116 are meshed and connected to the third bevel gear 118 arranged on the output shaft of the motor 117; the motor 117 drives the first bevel gear 115 and the second bevel gear 116 to rotate in opposite directions, and the first bevel gear 115 and the second bevel gear 116 respectively drive the first gear 111 and the second gear 112 to rotate; the first gear 111 and the second gear 112 respectively drive the first toothed ring 14 and the second toothed ring 15 to move in opposite directions. A pipeline corrosion detector body 119 is also installed on the top of the right-angle block 1, and the pipeline corrosion detector body 119 is connected to the corrosion detection head 18.

[0036] T-shaped arc grooves 17 are respectively opened on the sides of the first toothed ring 14 and the second toothed ring 15; T-shaped arc blocks 19 are arranged at positions corresponding to the T-shaped arc grooves 17 on the inner wall of the arc-shaped groove 11; the T-shaped arc blocks 19 are embedded in the T-shaped arc grooves 17 to limit the movement paths of the first toothed ring 14 and the second toothed ring 15, ensuring that the two move along the two side walls of the arc-shaped groove 11 respectively to prevent friction caused by mutual contact during their movement.

A roller 22 is rotatably arranged between the two L-shaped rods 21 on one side surface, and this side surface is parallel to the plane where the first toothed ring 14 or the second toothed ring 15 is located; by designing two rollers 22, the shale oil fracturing pipeline corrosion monitoring device as a whole can be moved along the pipeline to be detected during detection.
