[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model embodiment provides an oilfield corrosion monitoring device, such as Figure 1-6 As shown, the oilfield corrosion monitoring equipment includes: a mounting shell 1; a plurality of first telescopic rods 2 fixedly mounted on the inner wall of the mounting shell 1, a walking mechanism 3 fixedly mounted on the output shaft of the first telescopic rod 2, and the walking mechanism 3 is used to drive the mounting shell 1 to move on the oilfield pipeline; a mounting ring 4 rotatably mounted on the inner wall of the mounting shell 1; an ultrasonic thickness gauge 5 arranged on the mounting ring 4, and the ultrasonic thickness gauge 5 is used to monitor the thickness of the oilfield pipeline, and the ultrasonic thickness gauge 5 includes a host 501 and a probe 502, and the probe 502 is arranged on the host 501, and a second telescopic rod 401 is arranged on the mounting ring 4, and the output shaft of the second telescopic rod 401 is fixedly connected to the probe 502; a rotating mechanism 6 arranged on the mounting shell 1 and the mounting ring 4, and the rotating mechanism 6 is used to drive the ultrasonic thickness gauge 5 on the mounting ring 4 to rotate; a coating mechanism 7 arranged on the mounting ring 4, and the coating mechanism 7 is used to coat the coupling agent on the outer wall of the oilfield pipeline.

[0025] In this embodiment, according to the size of the oil field pipeline to be monitored, the installation shell 1 is placed outside the oil field pipeline, and the first telescopic rod 2 drives the walking mechanism 3 to contact the outer wall of the oil field pipeline, so that the installation shell 1 is fixed on the outer wall of the oil field pipeline. When it is necessary to monitor the corrosion of the corresponding position of the outer wall of the oil field pipeline, the coating head 704 on the coating mechanism 7 is first adjusted to the top of the probe 502 through the adjustment mechanism 8, and then the coating mechanism 7 is started through the controller (the controller can be connected to the background computer equipment, and the setting and operation are performed through the controller. This is a prior art and will not be described in detail here). Coupling agent is applied to the outer wall of the oil field pipeline. After the coating is completed, After completion, the controller resets the coating head 704 to avoid obstruction to the probe 502. The coupling agent can eliminate the air layer between the probe 502 and the outer wall of the oilfield pipeline, so that the ultrasonic wave can be transmitted more effectively, thereby improving the accuracy of measuring the thickness of the oilfield pipeline, and then improving the accuracy of measuring the corrosion of the oilfield pipeline. Then, the second telescopic rod 401 drives the probe 502 to move and contact the outer wall of the oilfield pipeline coated with the coupling agent. Through the cooperation of the host 501 and the probe 502, the thickness of the oilfield pipeline can be measured. By comparing the measured data with the original wall thickness of the oilfield pipeline, the corrosion of the oilfield pipeline can be monitored.

[0026] At the same time, when it is necessary to perform corrosion measurement on different lateral positions of the oilfield pipeline, the controller starts the walking mechanism 3, thereby driving the ultrasonic thickness gauge 5 in the installation shell 1 to move on the outer wall of the oilfield pipeline. Similarly, the above steps are performed to facilitate corrosion measurement at different lateral positions of the oilfield pipeline. When it is necessary to perform corrosion monitoring on the longitudinal direction of the oilfield pipeline (that is, to perform corrosion monitoring on different positions of the oilfield pipeline in a circle), the controller starts the rotating mechanism 6 to drive the mounting ring 4 to rotate, thereby driving the ultrasonic thickness gauge 5 to rotate on the outer wall of the oilfield pipeline. Similarly, corrosion monitoring operations are performed on different longitudinal positions of the oilfield pipeline. The entire device can perform corrosion monitoring operations on the oilfield pipeline, and can perform flexible corrosion monitoring operations on different positions of the oilfield pipeline. Coupling agent can be applied to the position that needs to be monitored to eliminate the air layer between the probe 502 and the outer wall of the oilfield pipeline, so that the ultrasonic wave can be transmitted more effectively, thereby improving the accuracy of thickness measurement of the oilfield pipeline.

[0027] In a further preferred embodiment of the utility model, the walking mechanism 3 includes: a mounting frame 301 fixedly mounted on the output shaft of the first telescopic rod 2; a driving motor 302 fixedly mounted on the mounting frame 301; a mounting shaft 303 rotatably mounted on the mounting frame 301, one end of the mounting shaft 303 is fixedly connected to the output shaft of the driving motor 302; and a walking wheel 304 fixedly sleeved on the mounting shaft 303.

[0028] In this embodiment, when the walking mechanism 3 is used, the controller starts the driving motor 302 to drive the walking wheel 304 on the mounting shaft 303 to rotate, so that the ultrasonic thickness gauge 5 in the mounting shell 1 can be moved on the outer wall of the oilfield pipeline. Similarly, the above steps are performed to facilitate corrosion measurement at different lateral positions of the oilfield pipeline.

[0029] In a further preferred embodiment of the utility model, the rotating mechanism 6 includes: a servo motor 601 fixedly mounted on the inner wall of the mounting shell 1; a first circular gear 602 fixedly sleeved on the output shaft of the servo motor 601; and a second circular gear 603 fixedly sleeved on the mounting ring 4, and the second circular gear 603 and the first circular gear 602 are meshed with each other.

[0030] In this embodiment, when the rotating mechanism 6 is used, the servo motor 601 is started by the controller, and the interaction between the second circular gear 603 and the first circular gear 602 can drive the ultrasonic thickness gauge 5 on the mounting ring 4 to rotate on the outer wall of the oil field pipeline, thereby performing corrosion monitoring operations on different longitudinal positions of the oil field pipeline.

[0031] In a further preferred embodiment of the utility model, the coating mechanism 7 includes: a placement box 701 fixedly mounted on the mounting ring 4, the placement box 701 is used to place the coupling agent; a loading pump 702 fixedly mounted in the placement box 701, a hose 703 is provided on the discharge end of the loading pump 702, and a coating head 704 is provided on the hose 703.

[0032] In this embodiment, before the probe 502 is used to contact the outer wall of the oil field pipeline, the controller will first adjust the coating head 704 to the top of the probe 502 through the adjustment mechanism 8, and at the same time move the coating head 704 to contact the outer wall of the oil field pipeline. The controller starts the feeding pump 702, and the coupling agent enters the coating head 704 through the hose 703, so that the coupling agent is applied to the outer wall of the oil field pipeline. After the coating is completed, the controller starts the adjustment mechanism 8 to reset the coating head 704 to avoid obstruction to the probe 502. The coupling agent can eliminate the probe 502 and the oil field pipeline. The air layer between the outer wall of the oilfield pipeline enables ultrasonic waves to propagate more effectively, thereby improving the accuracy of measuring the thickness of the oilfield pipeline, and further improving the accuracy of measuring the corrosion of the oilfield pipeline. After the coupling agent is applied, the controller starts the second telescopic rod 401 to drive the probe 502 to move and contact the outer wall of the oilfield pipeline coated with the coupling agent. Through the cooperation of the host 501 and the probe 502, the thickness of the oilfield pipeline can be measured.

[0034] In this embodiment, before applying the coupling agent to the oil field pipeline, the controller will start the power motor 801 to drive the mounting plate 803 to rotate, thereby adjusting the coating head 704 to the top of the probe 502, and then the controller will start the third telescopic rod 804 to drive the coating head 704 to move and contact the outer wall of the oil field pipeline, and then the coupling agent is applied through the coating mechanism 7. After the coating is completed, the adjustment mechanism 8 resets the coating head 704 to avoid obstruction to the probe 502.
